Abstract: The objectives of NSTX-U research are to reinforce the advantages of STs while addressing the challenges. To extend confinement physics of low- A , high beta plasmas to lower collisionality levels, understanding of the transport mechanisms that set confinement performance and pedestal profiles is being advanced through gyrokinetic simulations, reduced model development, and comparison to NSTX experiment, as well as improved simulation of RF heating. To develop stable non-inductive scenarios needed for steady-state operation, various performance-limiting modes of instability were studied, including MHD, tearing modes, and energetic particle instabilities. Predictive tools were developed, covering disruptions, runaway electrons, equilibrium reconstruction, and control tools. To develop power and particle handling techniques to optimize plasma exhaust in high performance scenarios, innovative lithium-based solutions are being developed to handle the very high heat flux levels that the increased heating power and compact geometry of NSTX-U will produce, and will be seen in future STs. Predictive capabilities accounting for plasma phenomena, like edge harmonic oscillations, ELMs, and blobs, are being tested and improved. In these ways, NSTX-U researchers are advancing the physics understanding of ST plasmas to maximize the benefit that will be gained from further NSTX-U experiments and to increase confidence in projections to future devices.

2. Machine learning-enhanced model-based scenario optimization for DIII-D

Author: S. Morosohk, B. Leard, T. Rafiq, and E. Schuster
Subjects: tokamak control, scenario optimization, neural network surrogate model, Nuclear and particle physics. Atomic energy. Radioactivity, QC770-798
Abstract: Scenario development in tokamaks is an open area of investigation that can be approached in a variety of different ways. Experimental trial and error has been the traditional method, but this required a massive amount of experimental time and resources. As high fidelity predictive models have become available, offline development and testing of proposed scenarios has become an option to reduce the required experimental resources. The use of predictive models also offers the possibility of using a numerical optimization process to find the controllable inputs that most closely achieve the desired plasma state. However, this type of optimization can require as many as hundreds or thousands of predictive simulation cases to converge to a solution; many of the commonly used high fidelity models have high computational burdens, so it is only reasonable to run a handful of predictive simulations. In order to make use of numerical optimization approaches, a compromise needs to be found between model fidelity and computational burden. This compromise can be achieved using neural networks surrogates of high fidelity models that retain nearly the same level of accuracy as the models they are trained to replicate while reducing the computation time by orders of magnitude. In this work, a model-based numerical optimization tool for scenario development is described. The predictive model used by the optimizer includes neural network surrogate models integrated into the fast Control-Oriented Transport simulation framework. This optimization scheme is able to converge to the optimal values of the controllable inputs that produce the target plasma scenario by running thousands of predictive simulations in under an hour without sacrificing too much prediction accuracy.

3. Predictive modeling of NSTX discharges with the updated multi-mode anomalous transport module

Author: T. Rafiq, C. Wilson, C. Clauser, E. Schuster, J. Weiland, J. Anderson, S.M. Kaye, A. Pankin, B.P. LeBlanc, and R.E. Bell
Subjects: transport, NSTX, predictive simulation, tokamak, multi-mode module, Nuclear and particle physics. Atomic energy. Radioactivity, QC770-798
Abstract: The objective of this study is twofold: firstly, to demonstrate the consistency between the anomalous transport results produced by updated Multi-Mode Model (MMM) version 9.0.4 and those obtained through gyrokinetic simulations; and secondly, to showcase MMM’s ability to predict electron and ion temperature profiles in low aspect ratio, high beta NSTX discharges. MMM encompasses a range of transport mechanisms driven by electron and ion temperature gradients, trapped electrons, kinetic ballooning, peeling, microtearing, and drift resistive inertial ballooning modes. These modes within MMM are being verified through corresponding gyrokinetic results. The modes that potentially contribute to ion thermal transport are stable in MMM, aligning with both experimental data and findings from linear CGYRO simulations. The isotope effects on these modes are also studied and higher mass is found to be stabilizing, consistent with the experimental trend. The electron thermal power across the flux surface is computed within MMM and compared to experimental measurements and nonlinear CGYRO simulation results. Specifically, the electron temperature gradient modes (ETGM) within MMM account for 2.0 MW of thermal power, consistent with experimental findings. It is noteworthy that the ETGM model requires approximately 5.0 ms of computation time on a standard desktop, while nonlinear CGYRO simulations necessitate 8.0 h on 8 K cores. MMM proves to be highly computationally efficient, a crucial attribute for various applications, including real-time control, tokamak scenario optimization, and uncertainty quantification of experimental data.

4. Facility-scale inventory of dairy methane emissions in California: implications for mitigation

Author: A. R. Marklein, D. Meyer, M. L. Fischer, S. Jeong, T. Rafiq, M. Carr, and F. M. Hopkins
Subjects: Environmental sciences, GE1-350, Geology, QE1-996.5
Abstract: Dairies emit roughly half of total methane (CH4) emissions in California, generating CH4 from both enteric fermentation by ruminant gut microbes and anaerobic decomposition of manure. Representation of these emission processes is essential for management and mitigation of CH4 emissions and is typically done using standardized emission factors applied at large spatial scales (e.g., state level). However, CH4-emitting activities and management decisions vary across facilities, and current inventories do not have sufficiently high spatial resolution to capture changes at this scale. Here, we develop a spatially explicit database of dairies in California, with information from operating permits and California-specific reports detailing herd demographics and manure management at the facility scale. We calculated manure management and enteric fermentation CH4 emissions using two previously published bottom-up approaches and a new farm-specific calculation developed in this work. We also estimate the effect of mitigation strategies – the use of mechanical separators and installation of anaerobic digesters – on CH4 emissions. We predict that implementation of digesters at the 106 dairies that are existing or planned in California will reduce manure CH4 emissions from those facilities by an average of 26 % and total state CH4 emissions by 5 % (or ∼36.5 Gg CH4/yr). In addition to serving as a planning tool for mitigation, this database is useful as a prior for atmospheric observation-based emissions estimates, attribution of emissions to a specific facility, and validation of CH4 emissions reductions from management changes. Raster files of the datasets and associated metadata are available from the Oak Ridge National Laboratory Distributed Active Archive Center for Biogeochemical Dynamics (ORNL DAAC; Marklein and Hopkins, 2020; https://doi.org/10.3334/ORNLDAAC/1814).

5. Vista-LA: Mapping methane-emitting infrastructure in the Los Angeles megacity

Author: V. Carranza, T. Rafiq, I. Frausto-Vicencio, F. M. Hopkins, K. R. Verhulst, P. Rao, R. M. Duren, and C. E. Miller
Subjects: Environmental sciences, GE1-350, Geology, QE1-996.5
Abstract: Methane (CH4) is a potent greenhouse gas (GHG) and a critical target of climate mitigation efforts. However, actionable emission reduction efforts are complicated by large uncertainties in the methane budget on relevant scales. Here, we present Vista, a Geographic Information System (GIS)-based approach to map potential methane emissions sources in the South Coast Air Basin (SoCAB) that encompasses Los Angeles, an area with a dense, complex mixture of methane sources. The goal of this work is to provide a database that, together with atmospheric observations, improves methane emissions estimates in urban areas with complex infrastructure. We aggregated methane source location information into three sectors (energy, agriculture, and waste) following the frameworks used by the State of California GHG Inventory and the Intergovernmental Panel on Climate Change (IPCC) Guidelines for GHG Reporting. Geospatial modeling was applied to publicly available datasets to precisely geolocate facilities and infrastructure comprising major anthropogenic methane source sectors. The final database, Vista-Los Angeles (Vista-LA), is presented as maps of infrastructure known or expected to emit CH4. Vista-LA contains over 33 000 features concentrated on hotspot detection using regional observations. This study represents a first step towards developing an accurate, spatially resolved methane flux estimate for point sources in SoCAB, with the potential to address discrepancies between bottom–up and top–down methane emissions accounting in this region. The Vista-LA datasets and associated metadata are available from the Oak Ridge National Laboratory Distributed Active Archive Center for Biogeochemical Dynamics (ORNL DAAC; https://doi.org/10.3334/ORNLDAAC/1525).

6. Fast particles in drift wave turbulence

Author: J. Weiland, T. Rafiq, and E. Schuster
Subjects: Condensed Matter Physics
Abstract: This study aims to incorporate the effects of fast particles into our present fluid model for tokamak transport. The parameter ε f = ω / ω f, where ω is the mode frequency and ω f is the typical frequency of the fast particles, which enters as a factor in front of the fast particle response. Thus, for trapped fast particles, where ω f = ω pres the precession frequency of the fast particles, this parameter is of order 10 − 2 for drift waves, and thus, the fast particle response can be neglected. However, ε f will be of order 1 for fast particle modes such as in the fishbone instability. An important turbulence property, affecting both these limits, is resonance broadening. Effects of resonance broadening have recently been considered for fast particle instabilities, often coupled directly to the linear growth rate, while we here consider the original Dupree formulation where the turbulence directly drives a nonlinear frequency shift. Resonance broadening has a general tendency to counteract dissipative wave particle resonances. This has been observed for fast particle instabilities. Here, there is a resonant external source for the fast particles, so the instability survives if this source is dominant over the resonance broadening. For drift waves, however, external sources are not resonant since ε f ≪ 1. Thus, the resonance broadening is able to remove the dissipative wave particle resonance completely.

7. Нелінійні ефекти у фізиці та демографії

Author: J. Weiland and T. Rafiq

Abstract: Nonlinearities appear in almost all systems. Earlier, we focused on those in plasmas, ionospheric scattering, and the world population. As turned out, the estimate of the population growth made in 1974 is in astonishing agreement with the United Nations estimates and agrees with our present data to within 2%. A particularly important role, both for the population evolution and wave interaction in plasmas, is played by non-Markovian effects (effects depending on the past time). For the population growth, this occurs due to a delay of one generation in the set of population limiting actions, while, for plasmas, it is caused by nonlinear frequency shifts., Нелiнiйностi з’являються майже в усiх системах. Ранiше ми розглядали нелiнiйностi в плазмi, розсiюваннi в iоносферi, свiтовiй популяцiї. З’ясувалося, що оцiнка приросту населення, яка була зроблена в 1974 роцi, чудово узгоджується з оцiнками ООН i спiвпадає з нашими даними з точнiстю 2%. Особливо важливими для еволюцiї населення та взаємодiї хвиль у плазмi є немарковськi ефекти (вони залежать вiд минулих часiв). Для приросту населення це пов’язано iз затримкою на одне поколiння впливу факторiв, що обмежують популяцiю, тодi як для плазми це викликано нелiнiйними зсувами частоти.

Abstract: Funding Information: This material is based upon work supported by the US Department of Energy, Office of Science, Office of Fusion Energy Sciences, using the DIII-D National Fusion Facility, a DOE Office of Science user facility, under Awards DE-FC02-04ER54698 and DE-AC52-07NA27344. Publisher Copyright: © 2022 IAEA, Vienna. DIII-D physics research addresses critical challenges for the operation of ITER and the next generation of fusion energy devices. This is done through a focus on innovations to provide solutions for high performance long pulse operation, coupled with fundamental plasma physics understanding and model validation, to drive scenario development by integrating high performance core and boundary plasmas. Substantial increases in off-axis current drive efficiency from an innovative top launch system for EC power, and in pressure broadening for Alfven eigenmode control from a co-/counter-I p steerable off-axis neutral beam, all improve the prospects for optimization of future long pulse/steady state high performance tokamak operation. Fundamental studies into the modes that drive the evolution of the pedestal pressure profile and electron vs ion heat flux validate predictive models of pedestal recovery after ELMs. Understanding the physics mechanisms of ELM control and density pumpout by 3D magnetic perturbation fields leads to confident predictions for ITER and future devices. Validated modeling of high-Z shattered pellet injection for disruption mitigation, runaway electron dissipation, and techniques for disruption prediction and avoidance including machine learning, give confidence in handling disruptivity for future devices. For the non-nuclear phase of ITER, two actuators are identified to lower the L-H threshold power in hydrogen plasmas. With this physics understanding and suite of capabilities, a high poloidal beta optimized-core scenario with an internal transport barrier that projects nearly to Q = 10 in ITER at ∼8 MA was coupled to a detached divertor, and a near super H-mode optimized-pedestal scenario with co-I p beam injection was coupled to a radiative divertor. The hybrid core scenario was achieved directly, without the need for anomalous current diffusion, using off-axis current drive actuators. Also, a controller to assess proximity to stability limits and regulate β N in the ITER baseline scenario, based on plasma response to probing 3D fields, was demonstrated. Finally, innovative tokamak operation using a negative triangularity shape showed many attractive features for future pilot plant operation.

11. Linear ion-scale microstability analysis of high and low-collisionality NSTX discharges and NSTX-U projections

Author: C. F. Clauser, W. Guttenfelder, T. Rafiq, and E. Schuster
Subjects: Condensed Matter Physics
Abstract: Linear gyrokinetic simulations were conducted to investigate ion-gyroradius-scale micro-instability predictions for high-beta NSTX discharges and NSTX-U projections that span over an order of magnitude variation in collisionality. A complex mix of microtearing modes and hybrid trapped electron modes/kinetic ballooning modes (TEM/KBM) is predicted for all experimental or projected conditions. Ion temperature gradient (ITG) instabilities are typically stable in the NSTX discharges investigated, consistent with the observed neoclassical ion thermal transport. ITG thresholds inferred from the simulations are typically much higher than the experimental NSTX gradients, as well as the projected gradients in the NSTX-U scenario, which assumed ion temperatures limited by neoclassical transport only. The analysis suggests ITG instabilities are unlikely to contribute significant anomalous thermal losses in high-beta, lower collisionality NSTX-U scenarios. On the other hand, the NSTX experimental profiles and NSTX-U projections are predicted to be very close to the predicted onset of unstable KBM at most radii investigated. The proximity of the various discharges to the KBM instability threshold implies it may play an important role in setting profile shapes and limiting global energy confinement. It remains to be understood and predicted how KBM contributes to multi-channel transport (thermal and particle transport, for both ions and electrons) in a way that is consistent with experimental inferences.

12. Electron temperature gradient driven transport model for tokamak plasmas

Author: T. Rafiq, C. Wilson, L. Luo, J. Weiland, E. Schuster, A. Y. Pankin, W. Guttenfelder, and S. Kaye
Subjects: Condensed Matter Physics
Abstract: A new model for electron temperature gradient (ETG) modes is developed as a component of the multi-mode anomalous transport module [Rafiq et al., Phys Plasmas 20, 032506 (2013)] to predict a time-dependent electron temperature profile in conventional and low aspect ratio tokamaks. This model is based on two-fluid equations that govern the dynamics of low-frequency short- and long-wavelength electromagnetic toroidal ETG driven drift modes. A low collisionality NSTX discharge is used to scan the plasma parameter dependence on the ETG real frequency, growth rate, and electron thermal diffusivity. Electron thermal transport is discovered in the deep core region where modes are more electromagnetic in nature. Several previously reported gyrokinetic trends are reproduced, including the dependencies of density gradients, magnetic shear, β and gradient of β [Formula: see text], collisionality, safety factor, and toroidicity, where β is the ratio of the plasma pressure to the magnetic pressure. The electron heat diffusivity associated with the ETG mode is discovered to be on a scale consistent with the experimental diffusivity determined by power balance analysis.

Abstract: DIII-D research is addressing critical challenges in preparation for ITER and the next generation of fusion devices through focusing on plasma physics fundamentals that underpin key fusion goals, understanding the interaction of disparate core and boundary plasma physics, and developing integrated scenarios for achieving high performance fusion regimes. Fundamental investigations into fusion energy science find that anomalous dissipation of runaway electrons (RE) that arise following a disruption is likely due to interactions with RE-driven kinetic instabilities, some of which have been directly observed, opening a new avenue for RE energy dissipation using naturally excited waves. Dimensionless parameter scaling of intrinsic rotation and gyrokinetic simulations give a predicted ITER rotation profile with significant turbulence stabilization. Coherence imaging spectroscopy confirms near sonic flow throughout the divertor towards the target, which may account for the convection-dominated parallel heat flux. Core-boundary integration studies show that the small angle slot divertor achieves detachment at lower density and extends plasma cooling across the divertor target plate, which is essential for controlling heat flux and erosion. The Super H-mode regime has been extended to high plasma current (2.0 MA) and density to achieve very high pedestal pressures (~30 kPa) and stored energy (3.2 MJ) with H 98y2 ≈ 1.6–2.4. In scenario work, the ITER baseline Q = 10 scenario with zero injected torque is found to have a fusion gain metric independent of current between q 95 = 2.8–3.7, and a lower limit of pedestal rotation for RMP ELM suppression has been found. In the wide pedestal QH-mode regime that exhibits improved performance and no ELMs, the start-up counter torque has been eliminated so that the entire discharge uses ≈0 injected torque and the operating space is more ITER-relevant. Finally, the high- (⩽3.8) hybrid scenario has been extended to the high-density levels necessary for radiating divertor operation, achieving ~40% divertor heat flux reduction using either argon or neon with P tot up to 15 MW.

Abstract: DIII-D research is addressing critical challenges in preparation for ITER and the next generation of fusion devices through focusing on plasma physics fundamentals that underpin key fusion goals, understanding the interaction of disparate core and boundary plasma physics, and developing integrated scenarios for achieving high performance fusion regimes. Fundamental investigations into fusion energy science find that anomalous dissipation of runaway electrons (RE) that arise following a disruption is likely due to interactions with RE-driven kinetic instabilities, some of which have been directly observed, opening a new avenue for RE energy dissipation using naturally excited waves. Dimensionless parameter scaling of intrinsic rotation and gyrokinetic simulations give a predicted ITER rotation profile with significant turbulence stabilization. Coherence imaging spectroscopy confirms near sonic flow throughout the divertor towards the target, which may account for the convection-dominated parallel heat flux. Core-boundary integration studies show that the small angle slot divertor achieves detachment at lower density and extends plasma cooling across the divertor target plate, which is essential for controlling heat flux and erosion. The Super H-mode regime has been extended to high plasma current (2.0 MA) and density to achieve very high pedestal pressures (∼30 kPa) and stored energy (3.2 MJ) with H 98y2 ≈ 1.6-2.4. In scenario work, the ITER baseline Q = 10 scenario with zero injected torque is found to have a fusion gain metric independent of current between q 95 = 2.8-3.7, and a lower limit of pedestal rotation for RMP ELM suppression has been found. In the wide pedestal QH-mode regime that exhibits improved performance and no ELMs, the start-up counter torque has been eliminated so that the entire discharge uses ≈0 injected torque and the operating space is more ITER-relevant. Finally, the high- (3.8) hybrid scenario has been extended to the high-density levels ne

Subjects: Physics, Thermonuclear fusion, Tokamak, Plasma, Mechanics, Eigenfunction, Condensed Matter Physics, Instability, Atomic and Molecular Physics, and Optics, WKB approximation, Magnetic flux, Magnetic field, law.invention, Classical mechanics, law, Mathematical Physics
Abstract: The influence of details of an international thermonuclear experimental reactor (ITER)-like geometry on drift wave stability is studied. The eigenvalue problem for electrostatic electron drift waves is solved numerically by following the ballooning mode formalism and using a standard shooting technique. The real frequencies and growth rates of the most unstable modes and their eigenfunctions are calculated for two specific magnetic flux surfaces. For the equilibrium under investigation, the modes are found to be unstable for peak density profiles and their stability is found to be strongly affected by the local magnetic shear (LMS). The presence of positive LMS is found to be destabilizing on the magnetic surface where global magnetic shear is reverse. The stability behaviour is however different for a positive magnetic shear surface where the effect of large positive LMS is found to be stabilizing. The eigenfunctions are more localized in the regions where normal curvature is bad and magnetic field is weak.

17. Anomalous Heat Transport and Vortex Formation Due to Electron–Temperature–Gradient Driven Drift Waves In a Sheared Flow Plasma

Author: Ghulam Murtaza, Arshad M. Mirza, R. T. Faria, T Rafiq, Anisa Qamar, and Padma Kant Shukla
Subjects: Physics, Condensed matter physics, Plasma, Mechanics, Electron, Condensed Matter Physics, Electromagnetic radiation, Atomic and Molecular Physics, and Optics, Vortex, Nonlinear system, Dipole, Flow (mathematics), Electron temperature, Mathematical Physics
Abstract: By employing Braginskii transport equations for electrons, we derive a system of nonlinear equations which govern the dynamics of low-frequency short–wavelength electromagnetic waves in the presence of equilibrium density, temperature and magnetic field gradients. New electron-temperature-gradient driven electromagnetic drift–wave instabilities are shown to exist. Anomalous electron energy transport caused by nonthermal electromagnetic fluctuations is also derived. Furthermore, possible stationary solutions of the nonlinear system are obtained in the form of spatially bounded dipolar as well as chain of vortices. The results of our investigations should be helpful to understand the wave phenomena in space and laboratory plasmas.

18. Accumulation of chromium in pak choi ( L.) grown on representative chinese soils

Author: Wendan, Xiao, Xiaoe, Yang, Yibin, Zhang, M T, Rafiq, Zhenli, He, R, Aziz, and Tingqiang, Li
Subjects: Chromium, China, Soil, Vegetables, Humans, Soil Pollutants, Agriculture
Abstract: Anthropogenic chromium (Cr) pollution in soils poses a great threat to human health through the food chain. It is imperative to understand Cr accumulation properties in common vegetables because the proportion of vegetables consumed has increased with the improvement of living standards. This study investigated Cr accumulation in pak choi ( L.) grown on six representative agricultural soils in China. Chromium concentration in the edible parts of pak choi generally increased with soil Cr concentrations following the order: Ustic CambosolsPeriudic ArgosolsMollisolsCalcaric RegosolsStagnic AnthrosolsUdic Ferrisols. Simple correlation analysis indicated that Cr concentration in pak choi was significantly correlated with the total Cr, Mehlich-3-extractable Cr, and Cr(VI). Stepwise multiple regression analysis also demonstrated that the phytoavailability of Cr was strongly correlated with the extractable fraction by Mehlich-3, total Cr concentration, soil organic matter, and Fe(II). Critical Cr concentrations in these six soils were evaluated for pak choi based on the maximum safe level for daily intake of Cr. Total soil Cr can be used as Cr thresholds for potential dietary toxicity in pak choi. Mehlich-3-extractable Cr is most suitable to be used as Cr thresholds for Periudic Argosols, Udic Ferrisols, Mollisols, and Ustic Cambosols, with values of 20.7, 15.8, 21.2, and 20.4 mg kg, respectively, whereas Cr(VI) is most suitable for Calcaric Regosols and Stagnic Anthrosols, with values of 26.5 and 28.0 mg kg, respectively.

Abstract: ITER simulations, in which the temperatures, toroidal angular frequency and currents are evolved, are carried out using the PTRANSP code starting with initial profiles and boundary conditions obtained from TSC code studies. The dependence of heat deposition and current drive on ICRF frequency, number of poloidal modes, beam orientation, number of Monte Carlo particles and ECRH launch angles is studied in order to examine various possibilities and contingencies for ITER steady state and hybrid discharges. For the hybrid discharges, the fusion power production and fusion Q, computed using the Multi‐Mode MMM v7.1 anomalous transport model, are compared with those predicted using the GLF23 model. The simulations of the hybrid scenario indicate that the fusion power production at 1000 sec will be approximately 500 MW corresponding to a fusion Q = 10.0. The discharge scenarios simulated aid in understanding the conditions for optimizing fusion power production and in examining measures of plasma performance.

Abstract: Abstract Malakand region is an endemic area for cutaneous leishmaniasis (CL). However, there are limited number of studies of this disease in Pakistan. Therefore, a study was conducted to understand the level of awareness attitude and practice among the residents of Makaland towards CL and the disease vectors. This study adopted a cross-sectional approach with a total of 400 respondents (n=93 rural and n= 307 urban). Overall, the population in Malakand region (61.2%) were well-informed in the role of sand fly in transmitting diseases, but most lack knowledge on the vector’s behavior and almost a quarter (24.5%) were unable to provide knowledge on proper control measures. Alarmingly, the practice and attitudes of the general population was not satisfactory as close to half (49.8%) of the population did adopt any control method. This study calls for increase in awareness through health education campaign to reduce the risk of cutaneous leishmaniasis outbreaks in the future.

Abstract: Standard protocol following total hip arthroplasty dictates that the hip is kept in a position of abduction until soft tissue healing is sufficient to provide stability. This is maintained by use of an abduction pillow while in bed, meaning that the patient must sleep on their back. Many patients find this position uncomfortable and have significant difficulty in sleeping. Aims: To assess the impact of sleep deprivation on recovery of the patient and quality of life in the peri-operative period. Methods: Patient cohort consisted of elective admissions for total hip replacement. All were assessed using the Epworth sleep scale, SF-36 as well as the Hospital Anxiety and depression score. Body mass index and history of insomnia or obstructive sleep apnoea were recorded. Baseline oxygen saturation was compared with postoperative overnight saturation and request for night sedation. Results: 64 consecutive patients undergoing total hip arthroplasty surgery were eligible for inclusion in the study. Mean age 68 (43 to 85), 42 females, 22 males, 62 patients were satisfied with the result of surgery, 1 patient with hip dysplasia had a persistent leg length inequality and one complained of back pain. All patients were nursed according to standard protocol with abduction pillow while in hospital and instructions to sleep on their back while at home. 18 patients did not fully comply with this instruction while at home. There were no early dislocations with a mean follow up of 5.4 months. Mean hospital anxiety and depression scores were significantly increased following surgery mean pre-operatively (5.2), to highest level (3.4) at two weeks, (8.5) at six weeks, returning to normal levels after three months (4.2). Epworth sleep scores were similarly increased with sleep patterns returning to normal at the three month stage. Increasingly, body mass index correlated significantly with poor scores and low oxygen saturation readings. This group of patients had a predisposition to obstructive sleep apnoea, which was predicated by sleeping on their backs, they require more night sedation and analgesia. Conclusions: Standard precautions following total hip arthroplasty are not without morbidity. Sleep deprivation leading to increased anxiety and decreased satisfaction. Increased demand for night sedation and analgesia with their resultant costs and dependence. Sleeping in the supine position may also precipitate obstructive sleep apnoea in at risk patients.

Abstract: Since the last IAEA conference, the scientific programme of JET has focused on the qualification of the integrated operating scenarios for ITER and on physics issues essential for the consolidation of design choices and the efficient exploitation of ITER. Particular attention has been given to the characterization of the edge plasma, pedestal energy and edge localized modes (ELMs), and their impact on plasma facing components (PFCs). Various ELM mitigation techniques have been assessed for all ITER operating scenarios using active methods such as resonant magnetic field perturbation, rapid variation of the radial field and pellet pacing. In particular, the amplitude and frequency of type I ELMs have been actively controlled over a wide parameter range (q(95) = 3-4.8, beta(N)

23. Anomalous transport in the H-mode pedestal of Alcator C-Mod discharges.

Author: A.Y. Pankin, J.W. Hughes, M.J. Greenwald, A.H. Kritz, and T. Rafiq
Subjects: H-mode plasma confinement, COLLISIONS (Physics), BALLOONING, THERMAL diffusivity, SIMULATION methods & models
Abstract: Anomalous transport in the H-mode pedestal region of five Alcator C-Mod discharges, representing a collisionality scan is analyzed. The understanding of anomalous transport in the pedestal region is important for the development of a comprehensive model for the H-mode pedestal slope. In this research, a possible role of the drift resistive inertial ballooning modes (Rafiq et al 2010 Phys. Plasmas17 082511) in the edge of Alcator C-Mod discharges is analyzed. The stability analysis, carried out using the TRANSP code, indicates that the DRIBM modes are strongly unstable in Alcator C-Mod discharges with large electron collisionality. An improved interpretive analysis of H-mode pedestal experimental data is carried out utilizing the additive flux minimization technique (Pankin et al 2013 Phys. Plasmas20 102501) together with the guiding-center neoclassical kinetic XGC0 code. The neoclassical and neutral physics are simulated in the XGC0 code and the anomalous fluxes are computed using the additive flux minimization technique. The anomalous fluxes are reconstructed and compared with each other for the collisionality scan Alcator C-Mod discharges. It is found that the electron thermal anomalous diffusivities at the pedestal top increase with the electron collisionality. This dependence can also point to the drift resistive inertial ballooning modes as the modes that drive the anomalous transport in the plasma edge of highly collisional discharges.

24. Van Neck-Odelberg Disease: A Systematic Review of Literature and Case Presentation.

Author: Sahu MA, Tahir A, Sahu MA, and Rafiq T
Abstract: Van Neck-Odelberg disease (VND) is a term used to describe ischiopubic osteochondritis, which typically presents with atraumatic unilateral groin pain. We performed a systematic review of the existing literature on reported cases of VND to collate what is already known. We also present a new case of VND to add to the relatively small body of literature on the topic. A systematic literature review was performed in July 2024 of PubMed, Medline, and Cochrane databases using the MeSH terms "van Neck Odelberg" to identify published articles. Inclusion criterion was defined as articles that provide individual details on cases of VND. Literature reviews without individual case details were excluded. Two authors independently screened titles and abstracts according to relevance and content. A total of 16 case reports and four case series were included in the final review, excluding our own case presentation. This review included 43 cases of VND (28 males and 15 females). There was no significant difference in average age of presentation between males and females. Majority of VND cases presented with unilateral pain (n=37), mainly in the groin (n=25) and typically non-radiating (n=18). Pain associated with VND most commonly occurred on the side of the non-dominant lower limb (n=8). Review findings demonstrated a common pattern of features associated with the presentation of VND, which included unilateral non-radiating groin pain occurring on the side of the non-dominant lower limb. Our case of a nine-year-old, left-foot dominant, boy who presented with atraumatic right-sided groin pain was in keeping with others reported from our review. MRI confirmed the diagnosis of VND in our case; repeat MRI after a period of activity modification and use of non-steroidal analgesics showed improvement in radiological appearance, and the patient showed improvement in function., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

25. Diet and Oral Health: An Investigation Into the Impact of Pakistani Dietary Habits on Oral Disease Prevalence.

Author: Rafiq T, Aqeel R, Javed M, Yousaf L, Bano S, and Akbar A
Abstract: Background Dietary habits play a significant role in the rising prevalence of oral health disorders, such as dental caries and periodontal diseases, particularly in regions like Pakistan with distinct dietary customs. Objective The primary objective of this research was to investigate the impact of Asian food on the prevalence of oral diseases, with a focus on identifying specific dietary factors that contribute to oral health issues. Methodology A cross-sectional study was carried out in Lahore between February and July 2024. The sample consisted of 384 adults aged 18 and above, selected based on specific inclusion and exclusion criteria. Data were collected through structured questionnaires assessing dietary habits and clinical examinations to diagnose oral diseases. Statistical analyses (SPSS version 26: (IBM Corp., Armonk, NY, USA), including correlation, regression, and Chi-Square, were used to evaluate the relationships between dietary patterns and oral health indicators. Results The study revealed significant correlations between dietary habits and oral disease prevalence. Among the 384 patients, 287 (74.74%) patients reported high sugar consumption, with a mean frequency of 3.26 times per week, correlating strongly with oral diseases (r=0.45, p<0.01). This group exhibited 179 patients (46.60%) with dental caries and 153 patients (39.58%) with periodontal conditions. Additionally, 262 patients (68.32%) with high carbohydrate intake, averaging 4.14 times per week, showed a moderate positive correlation with oral disease prevalence (r=0.32, p<0.05). Conversely, 193 patients (50.26%) who consumed fruits and vegetables with a mean frequency of 2.51 times per week demonstrated a significant negative correlation with oral disease prevalence (r=-0.40, p<0.01), indicating a protective effect. High sugar intake was associated with greater severity of oral diseases, with mean severity scores of 3.12 for dental caries and 3.20 for periodontal conditions. Conclusion The results show that although consuming more fruits and vegetables has a preventive effect, traditional Pakistani dietary practices, particularly excessive sugar and carbohydrate consumption, are associated with an increased incidence of oral illness., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

26. The Information Length Concept Applied to Plasma Turbulence.

Author: Anderson J, Imadera K, Moradi S, and Rafiq T
Abstract: A methodology to study statistical properties of anomalous transport in fusion plasma is investigated. Three time traces generated by the full-f gyrokinetic code GKNET are analyzed for this purpose. The time traces consist of heat flux as a function of the radial position, which is studied in a novel manner using statistical methods. The simulation data exhibit transport processes with both medium and long correlation length along the radius. A typical example of a phenomenon with long correlation length is avalanches. In order to investigate the evolution of the turbulent state, two basic configurations are studied, one flux-driven and one gradient-driven with decaying turbulence. The information length concept in tandem with Boltzmann-Gibbs and Tsallis entropy is used in the investigation. It is found that the dynamical states in both flux-driven and gradient-driven cases are surprisingly similar, but the Tsallis entropy reveals differences between them. This indicates that the types of probability distribution function are nevertheless quite different since the higher moments are significantly different.

Abstract: Objective: Red and processed meat is considered risk factors of gestational diabetes mellitus (GDM), but the evidence is inconclusive. We aimed to examine the association between red and processed meat intake and odds of GDM among South Asian and White European women living in Canada., Methods: This is a cross-sectional analysis of pregnant women from two birth cohorts: SouTh Asian biRth cohorT (START; n = 976) and Family Atherosclerosis Monitoring In earLY life (FAMILY; n = 581). Dietary intake was assessed using a validated 169-item semi-quantitative food-frequency questionnaire (FFQ). Multivariate logistic regression models were used to examine the associations between gestational diabetes and: 1) total red and processed meat; 2) unprocessed red meat; 3) processed meat and GDM after adjustment for potential confounders., Results: There were 241 GDM cases in START and 91 in FAMILY. The median total red and processed meat intake were 1.5 g/d (START) and 52.8 g/d (FAMILY). In START, the multivariable-adjusted odds ratio (OR) showed neither lower nor higher intakes of unprocessed red meat (p-trend = 0.68), processed meat (p-trend = 0.90), or total red and processed meat (p-trend = 0.44), were associated with increased odds of GDM, when compared with medium intake. Similar results were observed in FAMILY except for processed meat intake [OR = 0.94 (95% CI 0.47-1.91), for medium versus low and OR = 1.51 (95% CI 0.77-2.29) for medium versus high; p-trend = 0.18] after adjusting for additional dietary factors such as the diet quality score, total fiber, saturated fat and glycemic load., Conclusion: Medium compared with low or high red and processed meat intake is not associated with GDM in White Europeans and South Asians living in Canada., Competing Interests: Hertzel C.

Abstract: Objective: This study was conducted with the aim to establish standard technique of closed reduction (CR) and compare functional outcomes in patients of moderately displaced unilateral extracapsular condylar fractures., Material and Methods: This study is a retrospective randomized controlled trial, conducted at a tertiary care hospital setting from August, 2013 to November, 2018. Patients of unilateral extracapsular condylar fractures with ramus shortening < 7mm and deviation < 35° were divided in two groups by drawing lots and were treated by dynamic elastic therapy and maxillomandibular fixation (MMF). Mean and standard deviation were calculated for quantitative variables, and one way analysis of variance (ANOVA) and Pearson's Chi-square test were used to determine significance of outcomes between two modalities of CR. P value < 0.05 was taken as significant., Results: The numbers of patients treated by dynamic elastic therapy and MMF were 76 (38 in each group). Out of which 48 (63.15%) were male and 28 (36.84%) were female. The ratio of male to female was 1.7:1. The mean ± standard deviation (SD) of age was 32 ± 9.57 years. In patients treated by dynamic elastic therapy, the mean ± SD (at 6-month follow-up) of loss of ramus height (LRH), maximum incisal opening (MIO) and opening deviation were 4.6mm ± 1.08mm, 40.4mm ± 1.57mm and 1.1mm ± 0.87mm respectively. Whereas, LRH, MIO and opening deviation were 4.6mm ± 0.85mm, 40.4mm ± 2.37mm and 0.8mm ± 0.63mm respectively by MMF therapy. One-way ANOVA was statistically insignificant (P value > 0.05) for above mentioned outcomes. Pre-traumatic occlusion was achieved in 89.47% of patients by MMF and in 86.84% patients by dynamic elastic therapy. Pearson's Chi-square test was statistically insignificant (p value < 0.05) for occlusion., Conclusion: Parallel results were obtained for both modalities; thus, the technique as dynamic elastic therapy, which promotes early mobilization and functional rehabilitation, can be favored as standard technique of closed reduction for moderately displaced extracapsular condylar fractures. This technique eases patients' stress associated with MMF and prevents ankylosis., (© 2023. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

29. First-World Care at Third-World Rates: Pakistan, an Attractive Destination for Bariatric Tourism.

Author: Bashir U, Siddiq G, Saleem N, Farooq H, Awais M, Ussama M, Iqbal H, Shabbir H, Rafiq T, and Banoori M
Abstract: Introduction Obesity, a complex and multifactorial disease, is defined by a body mass index (BMI) greater than 30 kg/m². When the BMI exceeds 40 kg/m², it is classified as morbid obesity. This condition leads to excessive fat accumulation, which impairs normal body function and metabolism. For individuals grappling with morbid obesity and those who have faced significant hurdles in their quest for substantial weight loss, bariatric surgery emerges as a vital option. Purpose The study aims to explore the dynamics of bariatric surgical tourism in Pakistan, shedding light on factors influencing the choice of Pakistan as a destination for bariatric tourism. Materials and methods A retrospective cross-sectional study design was adopted. Data were gathered from the medical records database, including all patients who had undergone bariatric surgery from 2018 until 2022. The data collection process involved comprehensive patient outreach, where investigators conducted phone interviews and collected patient satisfaction assessments. During these phone interviews, valuable information was gathered by posing questions. These inquiries encompassed various aspects, including the patient's overall satisfaction with the surgical experience, their countries of origin, the specific bariatric procedures they underwent, the motivating factors behind their decision to travel abroad for surgery, their postoperative follow-up routines, and any complications they may have encountered. Results One hundred and nine patients traveled to Pakistan for bariatric surgery from 2018 to 2022. Out of 109 patients, 78 responded to the questionnaire by phone or email. The proforma was filled by 41 (52.5%) males and 37 (47.5%) females. Forty-seven (60.2%) of these patients underwent Roux-en-Y gastric bypass and 31 (39.8%) patients underwent sleeve gastrectomy. Out of 78 bariatric patients, 72 (92.3%) were satisfied with their surgery, five patients (6.4%) were neutral in their response and one patient (1.3%) was dissatisfied with the surgery. Most of the patients (26, 33.3%) declared money as the main driving force for traveling, with long waiting times being the close second reason (19, 24.36%) patients. Conclusion At least 2% of worldwide bariatric procedures are provided for medical tourists. Countries such as Mexico, India, Lebanon, and Romania dominate as providers for patients mainly from the USA, UK, and Germany. The lack of affordable bariatric healthcare and long waiting lists are some of the reasons for patients choosing bariatric tourism. The 92.3% satisfaction rate of patients with the surgery and its outcomes is a significant finding, as it suggests that bariatric surgery services provided in Pakistan are meeting or exceeding the expectations of international patients. The exceptionally high level of patient satisfaction speaks to the quality of care provided by the medical institutions in Pakistan. The data and analysis presented in this study shed light on the motivations and experiences of international patients traveling to Pakistan for bariatric surgery. These insights are invaluable for healthcare providers, policymakers, and the medical tourism industry as they seek to enhance the accessibility, affordability, and quality of healthcare services for domestic and international patients., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Bashir et al.)

31. Integrative multiomics analysis of infant gut microbiome and serum metabolome reveals key molecular biomarkers of early onset childhood obesity.

Author: Rafiq T, Stearns JC, Shanmuganathan M, Azab SM, Anand SS, Thabane L, Beyene J, Williams NC, Morrison KM, Teo KK, Britz-McKibbin P, and de Souza RJ
Abstract: Evidence supports a complex interplay of gut microbiome and host metabolism as regulators of obesity. The metabolic phenotype and microbial metabolism of host diet may also contribute to greater obesity risk in children early in life. This study aimed to identify features that discriminated overweight/obese from normal weight infants by integrating gut microbiome and serum metabolome profiles. This prospective analysis included 50 South Asian children living in Canada, selected from the SouTh Asian biRth cohorT (START). Serum metabolites were measured by multisegment injection-capillary electrophoresis-mass spectrometry and the relative abundance of bacterial 16S rRNA gene amplicon sequence variant was evaluated at 1 year. Cumulative body mass index (BMI AUC ) and skinfold thickness (SSF AUC ) scores were calculated from birth to 3 years as the total area under the growth curve (AUC). BMI AUC and/or SSF AUC >85th percentile was used to define overweight/obesity. Data Integration Analysis for Biomarker discovery using Latent cOmponent (DIABLO) was used to identify discriminant features associated with childhood overweight/obesity. The associations between identified features and anthropometric measures were examined using logistic regression. Circulating metabolites including glutamic acid, acetylcarnitine, carnitine, and threonine were positively, whereas γ-aminobutyric acid (GABA), symmetric dimethylarginine (SDMA), and asymmetric dimethylarginine (ADMA) were negatively associated with childhood overweight/obesity. The abundance of the Pseudobutyrivibrio and Lactobacillus genera were positively, and Clostridium sensu stricto 1 and Akkermansia were negatively associated with childhood overweight/obesity. Integrative analysis revealed that Akkermansia was positively whereas Lactobacillus was inversely correlated with GABA and SDMA, and Pseudobutyrivibrio was inversely correlated with GABA. This study provides insights into metabolic and microbial signatures which may regulate satiety, energy metabolism, inflammatory processes, and/or gut barrier function, and therefore, obesity trajectories in childhood. Understanding the functional capacity of these molecular features and potentially modifiable risk factors such as dietary exposures early in life may offer a novel approach for preventing childhood obesity., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

Abstract: Lead-free ceramics are promising candidates for replacing lead-based piezoelectric materials such as lead-zirconate-titanate (PZT) if they can compete in dielectric and ferroelectric characteristics. In this work, for lead-free piezoelectric ceramic, 0.74(Bi 0.5 Na 0.5 TiO 3 )-0.26(SrTiO 3 ) (BNT-ST26) and niobium-substituted (Nb-BNT-ST26) ceramics were synthesized by solid-state reactions. The evolution of niobium substitution to the perovskite phase structure of BNT-ST26 ceramics was confirmed by X-ray diffraction (XRD) analysis and Raman spectra. Electromechanical properties of Nb-BNT-ST26 ceramics initially increased with the addition of niobium up to 0.5% and decreased with a further increase in Nb content. Temperature-dependent dielectric curves showed that the depolarization temperature (T d ) decreased below room temperature because of Nb substitution. The composition with 0.5% Nb yielded a maximum bipolar strain (S max ) of 0.265% and normalized strain of d 33 * ~ 576 pm/V under an electric field of 4.6 kV/mm at room temperature. At this critical concentration of 0.5% Nb, maximum saturation polarization of 26 μC/cm 2 was achieved. The dielectric constant with temperature peaks became more diffused and the depolarization temperature decreased with the increasing Nb content. The study concludes that Nb-doped BNT-ST26 is an excellent material for high-temperature, stable, frequency-dependent, lead-free piezoelectric devices.

33. Use of Sacubitril/Valsartan Prior to Primary Prevention Implantable Cardioverter Defibrillator Implantation.

Author: Ozier D, Rafiq T, de Souza RJ, and Singh SM
Abstract: Background: Implantable cardioverter defibrillators (ICDs) are an adjunct to guideline-directed medical therapy for heart failure with reduced ejection fraction. The uptake of sacubitril/valsartan in this population is not well described. We report the uptake and factors associated with sacubitril/valsartan use in patients with left ventricular dysfunction undergoing ICD implantation., Methods: A retrospective chart review was performed on all patients with left ventricular dysfunction who underwent de novo primary prevention ICD implantation between October 2015 and December 2021 (n = 422) at Sunnybrook Health Sciences Centre, Toronto, Ontario, Canada. Pre-procedure sacubitril/valsartan use was determined. Logistic regression analysis was performed to examine factors associated with sacubitril/valsartan use. A Bayesian estimator of abrupt change was employed to determine a time period in which a change in the rate of sacubitril/valsartan use occurred., Results: Loop diuretic use (odds ratio [OR] = 2.20) and higher severity of New York Heart Association class symptoms (OR = 1.62) were associated with sacubitril/valsartan use. Sacubitril/valsartan use increased during the study period, to 59% in December 2021. This increase was larger among those aged ≥ 65 years (OR = 1.09). A change in the rate of sacubitril/valsartan use occurred 3 years after drug approval, 1 year after provincial drug coverage became available, and 6 months after being strongly recommended in clinical guidelines., Conclusions: In a contemporary cohort of ICD patients, sacubitril/valsartan use increased between 2015 and 2021, notably in those aged ≥ 65 years and after government drug coverage became available. Understanding barriers to sacubitril/valsartan use in ICD patients is recommended to improve clinical outcomes and survival in this population., (© 2022 The Authors.)

Abstract: The extent to which variation in food-related metabolites are attributable to non-dietary factors remains unclear, which may explain inconsistent food-metabolite associations observed in population studies. This study examined the association between non-dietary factors and the serum concentrations of food-related biomarkers and quantified the amount of variability in metabolite concentrations explained by non-dietary factors. Pregnant women ( n = 600) from two Canadian birth cohorts completed a validated semi-quantitative food frequency questionnaire, and serum metabolites were measured by multisegment injection-capillary electrophoresis-mass spectrometry. Hierarchical linear modelling and principal component partial R-square (PC-PR2) were used for data analysis. For proline betaine and DHA (mainly exogenous), citrus foods and fish/fish oil intake, respectively, explained the highest proportion of variability relative to non-dietary factors. The unique contribution of dietary factors was similar (15:0, 17:0, hippuric acid, TMAO) or lower (14:0, tryptophan betaine, 3-methylhistidine, carnitine) compared to non-dietary factors (i.e., ethnicity, maternal age, gestational age, pre-pregnancy BMI, physical activity, and smoking) for metabolites that can either be produced endogenously, biotransformed by gut microbiota, and/or derived from multiple food sources. The results emphasize the importance of adjusting for non-dietary factors in future analyses to improve the accuracy and precision of the measures of food intake and their associations with health and disease.

35. Nutritional Metabolomics and the Classification of Dietary Biomarker Candidates: A Critical Review.

Author: Rafiq T, Azab SM, Teo KK, Thabane L, Anand SS, Morrison KM, de Souza RJ, and Britz-McKibbin P
Subjects: Biomarkers, Fruit, Humans, Vegetables, Diet, Metabolomics
Abstract: Recent advances in metabolomics allow for more objective assessment of contemporary food exposures, which have been proposed as an alternative or complement to self-reporting of food intake. However, the quality of evidence supporting the utility of dietary biomarkers as valid measures of habitual intake of foods or complex dietary patterns in diverse populations has not been systematically evaluated. We reviewed nutritional metabolomics studies reporting metabolites associated with specific foods or food groups; evaluated the interstudy repeatability of dietary biomarker candidates; and reported study design, metabolomic approach, analytical technique(s), and type of biofluid analyzed. A comprehensive literature search of 5 databases (PubMed, EMBASE, Web of Science, BIOSIS, and CINAHL) was conducted from inception through December 2020. This review included 244 studies, 169 (69%) of which were interventional studies (9 of these were replicated in free-living participants) and 151 (62%) of which measured the metabolomic profile of serum and/or plasma. Food-based metabolites identified in ≥1 study and/or biofluid were associated with 11 food-specific categories or dietary patterns: 1) fruits; 2) vegetables; 3) high-fiber foods (grain-rich); 4) meats; 5) seafood; 6) pulses, legumes, and nuts; 7) alcohol; 8) caffeinated beverages, teas, and cocoas; 9) dairy and soya; 10) sweet and sugary foods; and 11) complex dietary patterns and other foods. We conclude that 69 metabolites represent good candidate biomarkers of food intake. Quantitative measurement of these metabolites will advance our understanding of the relation between diet and chronic disease risk and support evidence-based dietary guidelines for global health., (© The Author(s) 2021.

Subjects: Developing Countries, Humans, Cardiovascular Diseases epidemiology, Cardiovascular Diseases prevention & control, Heart Disease Risk Factors
Abstract: By the beginning of the 21st century, cardiovascular disease (CVD) had become the leading cause of premature mortality and morbidity worldwide, with 80% originating from less developed lower-income countries in line with societal and economic developments. Extensive research on causes and risk factors have been carried out since the mid-20th century and have established individual factors such as smoking, hypertension, diabetes, and dyslipidemia as CVD risk factors, followed by others. Two recent major case-control studies have summarized the role of common major CVD risk factors in determining the risk of myocardial infarction (INTERHEART study) and stroke (INTERSTROKE study). They showed that 9 and 10 common risk factors accounted for > 90% of the risk of myocardial infarction and stroke, respectively, and established the focus in prevention of these common CVDs. The efficacy of lowering blood pressure, blood glucose, and lipid-lowering therapies has been shown to reduce subsequent morbidity and mortality. Leading international health organizations have published guidelines that are updated regularly to set the standards for providing guidance for implementation and management of risk factors. Interventions can also be costly and long-term adherence, essential to be effective in reducing risks, tends to decrease drastically with time. Dietary recommendations have been incorporated into national and professional guidelines for CVD prevention since the 1960s. On the basis of new research, some existing dietary recommendation might be outdated and should be reviewed, and revised, if necessary. A perspective of CVD prevention and treatment in developing countries is highlighted., (Copyright © 2021 The Authors. Published by Elsevier Inc. All rights reserved.)

37. Adverse Childhood Experiences (ACEs) Predict Increased Arterial Stiffness from Childhood to Early Adulthood: Pilot Analysis of the Niagara Longitudinal Heart Study.

Author: Rafiq T, O'Leary DD, Dempster KS, Cairney J, and Wade TJ
Abstract: An association among adults between adverse childhood experiences (ACEs) and arterial stiffness and between arterial stiffness and cardiovascular disease has been established. Recent cross-sectional evidence suggests that ACEs is linked to the development and progression of arterial stiffness, but it remains unclear when these changes begin to manifest. We examine the relationship between ACEs and changes in arterial stiffness from childhood into adulthood using population-based longitudinal data. The Niagara Longitudinal Heart Study (NLHS) pilot data included 76 young adults (females = 44), with an average age of 21 years ( SD = 1), and had a follow-up period of 9 years. Mixed effects modeling was used to examine the effect of ACEs on changes in arterial stiffness over time adjusting for sex, changes in heart rate, systolic blood pressure, body mass index, and physical activity. Individuals with four or more ACEs have a greater increase in arterial stiffness over time from childhood into young adulthood. This increase was similar for both males and females and independent of the effects of change in heart rate, systolic blood pressure, body mass index, and physical activity. Exposure to ACEs is associated with greater increase in arterial stiffness, a marker for cardiovascular disease among adults. This suggests that interventions targeted at individuals with high exposure to ACEs early on in life could lower the risk of arterial stiffness and in turn the cascade of events leading to cardiovascular disease., Competing Interests: Conflict of InterestThe authors declare that they have no conflict of interest., (© Springer Nature Switzerland AG 2020.)

Abstract: Methane is a powerful greenhouse gas and is targeted for emissions mitigation by the US state of California and other jurisdictions worldwide 1,2 . Unique opportunities for mitigation are presented by point-source emitters-surface features or infrastructure components that are typically less than 10 metres in diameter and emit plumes of highly concentrated methane 3 . However, data on point-source emissions are sparse and typically lack sufficient spatial and temporal resolution to guide their mitigation and to accurately assess their magnitude 4 . Here we survey more than 272,000 infrastructure elements in California using an airborne imaging spectrometer that can rapidly map methane plumes 5-7 . We conduct five campaigns over several months from 2016 to 2018, spanning the oil and gas, manure-management and waste-management sectors, resulting in the detection, geolocation and quantification of emissions from 564 strong methane point sources. Our remote sensing approach enables the rapid and repeated assessment of large areas at high spatial resolution for a poorly characterized population of methane emitters that often appear intermittently and stochastically. We estimate net methane point-source emissions in California to be 0.618 teragrams per year (95 per cent confidence interval 0.523-0.725), equivalent to 34-46 per cent of the state's methane inventory 8 for 2016. Methane 'super-emitter' activity occurs in every sector surveyed, with 10 per cent of point sources contributing roughly 60 per cent of point-source emissions-consistent with a study of the US Four Corners region that had a different sectoral mix 9 . The largest methane emitters in California are a subset of landfills, which exhibit persistent anomalous activity. Methane point-source emissions in California are dominated by landfills (41 per cent), followed by dairies (26 per cent) and the oil and gas sector (26 per cent). Our data have enabled the identification of the 0.2 per cent of California's infrastructure that is responsible for these emissions. Sharing these data with collaborating infrastructure operators has led to the mitigation of anomalous methane-emission activity 10 .

Abstract: Background: Childhood obesity is a world-wide concern due to its growing prevalence and association with cardiometabolic risk factors in childhood and subsequent adult cardiovascular disease. In young pre-school children, there is uncertainty regarding which of the commonly used anthropometric measures of childhood obesity is best associated with cardiometabolic risk factors. This study compared the utility of common measures used in identifying obesity in these young children., Methods: The four commonly used metrics for identifying obesity in children: body fat percentage ≥ 90th percentile, waist circumference ≥ 90th percentile, BMI z score > 2 SD and waist-to-height ratio (WHtR) ≥ 0.5, were measured in a cohort of children born singleton, at full term and followed from birth (n = 761) to 5 years of age (n = 513). The utility of each in identifying cardiometabolic risk factors (fasting lipid profile, fasting blood glucose and blood pressure) was examined., Results: At age 5 years, children with percent body fat ≥ 90th percentile or waist circumference ≥ 90th percentile, were associated with higher levels of triglycerides, glucose, and systolic and diastolic blood pressures than those < 90th percentile, respectively. Such differences were not obvious at age 3 years or at birth. A BMI z-score > 2 SD was associated with higher levels of triglycerides and systolic and diastolic blood pressure but not glucose at age 5 years. Differences in HDL cholesterol, fasting glucose and systolic blood pressure were observed in children with BMI z score > 2 SD at age 3 years but not with the other indices of obesity. As almost all children had WHtR ≥ 0.5 at birth, ages 1 and 3 years, this measure could not differentiate increased cardiometabolic risk. At age 5 years, the differences were much more obvious, with significant differences in triglycerides and systolic and diastolic blood pressures between those with WHtR ≥ 0.5 and those with < 0.5., Conclusion: Each of the four commonly used measures of childhood obesity shows moderate associations with cardiometabolic risk factors at 5 years, with no advantage of one measure over the other. These associations were less consistent at 3 years of age or younger. These observations have not been reported previously., Competing Interests: The authors have declared that no competing interests exist.

40. Non-Linear Langevin and Fractional Fokker-Planck Equations for Anomalous Diffusion by Lévy Stable Processes.

Author: Anderson J, Moradi S, and Rafiq T
Abstract: The numerical solutions to a non-linear Fractional Fokker-Planck (FFP) equation are studied estimating the generalized diffusion coefficients. The aim is to model anomalous diffusion using an FFP description with fractional velocity derivatives and Langevin dynamics where Lévy fluctuations are introduced to model the effect of non-local transport due to fractional diffusion in velocity space. Distribution functions are found using numerical means for varying degrees of fractionality of the stable Lévy distribution as solutions to the FFP equation. The statistical properties of the distribution functions are assessed by a generalized normalized expectation measure and entropy and modified transport coefficient. The transport coefficient significantly increases with decreasing fractality which is corroborated by analysis of experimental data.

Abstract: Willow species have been suggested for use in the remediation of contaminated soils due to their high biomass production, fast growth, and high accumulation of heavy metals. The tolerance and accumulation of metals may vary among willow species and varieties, and the assessment of this variability is vital for selecting willow species/varieties for phytoremediation applications. Here, we examined the variations in lead (Pb) tolerance and accumulation of three cultivated varieties of Salix integra (Weishanhu, Yizhibi and Dahongtou), a shrub willow native to northeastern China, using hydroponic culture in a greenhouse. In general, the tolerance and accumulation of Pb varied among the three willow varieties depending on the Pb concentration. All three varieties had a high tolerance index (TI) and EC50 value (the effective concentration of Pb in the nutrient solution that caused a 50% inhibition on biomass production), but a low translocation factor (TF), indicating that Pb sequestration is mainly restricted in the roots of S. integra. Among the three varieties, Dahogntou was more sensitive to the increased Pb concentration than the other two varieties, with the lowest EC50 and TI for root and above-ground tissues. In this respect, Weishanhu and Yizhibi were more suitable for phytostabilization of Pb-contaminated soils. However, our findings also indicated the importance of considering the toxicity symptoms when selecting willow varieties for the use of phytoremediation, since we also found that the three varieties revealed various toxicity symptoms of leaf wilting, chlorosis and inhibition of shoot and root growth under the higher Pb concentrations. Such symptoms could be considered as a supplementary index in screening tests.

42. Renal tubular acidosis type II associated with vitamin D deficiency presenting as chronic weakness.

Author: Ali Y, Parekh A, Baig M, Ali T, and Rafiq T
Abstract: Chronic vitamin D deficiency, though common in the elderly, is often under diagnosed and when progressing to renal tubular acidosis type II (RTA 2) can cause several simultaneous electrolyte imbalances that may present with weakness and pain as chief symptoms. We present such a case that after months of evaluation and symptomatic treatment did not lead to an effective establishment of the etiology causing chronic weakness and body pain in an elderly female patient. Eventually, after a careful review of the patient's history, repeat physical examinations, laboratory data evaluation, and diagnostic testing led to the establishment of the diagnosis of proximal RTA 2 associated with vitamin D deficiency, which caused the patient to develop several remarkable secondary electrolyte imbalances such as hypokalemia, hypocalcemia, hypophosphatemia, acidemia, hyperparathyroidism, with weakness and body pain.

Abstract: Object: This study was designed to investigate the effect of treatment with a novel composite material consisting of embryonic neurospheres and bone marrow-derived stromal cell spheres (NMSCSs) in a rat model of traumatic brain injury (TBI)., Methods: The NMSCS composite was injected into the TBI contusion site 24 hours after injury, and all rats were killed on Day 14 after the transplantation. The Rotarod test and the neurological severity score were used to evaluate neurological function. The transplanted NMSCS was analyzed in recipient rat brains by using histological staining and laser scanning confocal microscopy. The lesion volumes in the brains were also calculated using computer image analysis., Conclusions: Rats that received NMSCS transplants had reduced lesion volume and showed improved motor and neurological function when compared with control groups 14 days after the treatment. These results suggest that transplantation of this novel biological material (NMSCS) may be useful in the treatment of TBI.
