Abstract

Background: Social distancing has been essential in mitigating the spread of the SARS-CoV-2 virus. Evidence regarding the impact of reduced social contact on mental health during the pandemic has been mixed, however, with studies suggesting that enduring personality traits and affect regulation impairments may together increase risk for suicidal distress during periods of lockdown. The present study utilized experience sampling and longitudinal follow-up methods to evaluate intolerance of aloneness (IA) as a predictor of suicidal ideation (SI) during the pandemic Methods: A general adult sample (n = 184) recruited online completed an 8-week experience sampling protocol via smartphone between April and September 2020. A subset of n = 69 participants completed a follow-up assessment of SI six months after the initial study period Results: IA was associated with suicidal ideation both at baseline and prospectively during the experience sampling period. Individuals with greater IA were more likely to report SI in the short-term context of reduced daily in-person social contact. Higher IA at baseline furthermore prospectively predicted the occurrence of SI during the 6-month follow-up period Limitations: The sample was relatively homogenous in terms of demographic characteristics and excluded individuals with limited access to communication technology. While statistical models accounted for current mental health treatment status, other factors that were not assessed (such as adverse events or psychiatric symptoms in non-treatment-seeking subjects) may have contributed to the development of SI Conclusions: Findings enhance understanding of how personality-based factors may contribute to suicide risk during periods of social distancing, informing both clinical treatment, risk assessment, and public health intervention approaches.

Abstract

Abstract During lockdowns associated with the COVID-19 pandemic, individuals have experienced poor sleep quality and sleep regularity, changes in lifestyle behaviours, and heightened depression and anxiety. However, the inter-relationship and relative strength of those behaviours on mental health outcomes is still unknown. We collected data between 12 May and 15 June 2020 from 1048 South African adults (age: 32.76 ± 14.43 years; n = 767 female; n = 473 students) using an online questionnaire. Using structural equation modelling, we investigated how insomnia symptoms, sleep regularity, exercise intensity/frequency and sitting/screen-use (sedentary screen-use) interacted to predict depressive and anxiety-related symptoms before and during lockdown. We also controlled for the effects of sex and student status. Irrespective of lockdown, (a) more severe symptoms of insomnia and greater sedentary screen-use predicted greater symptoms of depression and anxiety and (b) the effects of sedentary screen-use on mental health outcomes were mediated by insomnia. The effects of physical activity on mental health outcomes, however, were only significant during lockdown. Low physical activity predicted greater insomnia symptom severity, which in turn predicted increased depressive and anxiety-related symptoms. Overall, relationships between the study variables and mental health outcomes were amplified during lockdown. The findings highlight the importance of maintaining physical activity and reducing sedentary screen-use to promote better sleep and mental health.

Abstract

Abstract Epilepsy can occur in individuals with Down syndrome (DS), with epileptic spasms representing the most frequent seizure type in this population. Epileptic spasms can have devastating consequences on the development of individuals with the condition. This review sought to explore the lifetime prevalence and underlying mechanism of epileptic spasms in this population. We also aimed to review the response rate to various treatments, the relapse rate, and the development of subsequent epilepsy or autism in this population. A comprehensive literature search was conducted for articles discussing the lifetime prevalence, diagnosis, treatment, outcomes, or underlying etiology of epileptic spasms in animal models or individuals with DS. According to available literature, the global clinic‐based lifetime prevalence of epilepsy in individuals with DS ranged from 1.6% to 23.1%, with epileptic spasms representing 6.7%‐66.7% of these cases. Response rate to treatment with adrenocorticotropic hormone/corticosteroids was highest (81%) and has the most literature supporting its use, with other regimens, including vigabatrin and other antiepileptic drugs, having lower response rates. Epileptic spasms occur more frequently in children with DS than in the general population, though more studies are needed to determine the true lifetime prevalence of epileptic spasms in this population. Generally, children with DS and epileptic spasms tend to be more responsive to treatment and have better outcomes than children with epileptic spasms of unknown etiology (ie, without DS), in terms of response and relapse rates as well as the development of intractable epilepsy (eg, Lennox‐Gastaut syndrome).

Abstract

AimsTo systematically review randomised control trials (RCT's) assessing the effectiveness and safety of surgical interventions in adults with plantar fasciopathy (PF).Materials and methodsWe searched MEDLINE, EMBASE, Web of Science, Google Scholar, the Cochrane Central Register of Controlled Trials, trial registries and references lists. RCT's comparing surgical interventions with non-surgical or surgical comparisons in adults with PF were included. Primary outcomes were changes in first step pain severity/intensity, and incidence/nature of adverse events. Secondary outcomes included foot and ankle related disability/function, health related quality of life, cost effectiveness, changes in other reported measures of pain and medication use. Data were extracted at short-term (≤3 months post-intervention), medium-term (>3months-≤6 months post-intervention) or long-term (>6 months-≤2 years post-treatment). Certainty of evidence was evaluated using the modified Grading of Recommendations Assessment, Development and Evaluation (GRADE).ResultsFrom 3620 screened records, we included 8 studies comprising 345 patients. Substantial variation across trials precluded meta-analysis, hence a narrative synthesis was conducted. We judged all studies to have high risk of bias. For all outcome comparisons our GRADE judgement for the certainty of the evidence was very low. Three studies compared one type of surgery with another largely showing little to no difference in outcomes for pain, function or quality of life. Five studies compared surgery with non-surgical interventions-three providing very low certainty evidence that surgery may improve pain and function at long-term follow-up compared to non-surgical comparisons, whereas two studies provided no long-term between-group differences. Reporting of adverse events were inadequate, inconsistent or absent across all studies.ConclusionThere is a paucity of high certainty evidence to support or refute the effectiveness and safety of surgical interventions in the management of PF. We make recommendations for improving the evidence base in this field.

Abstract

In the G0 experiment, performed at Jefferson Lab, the parity-violating elastic scattering of electrons from protons and quasi-elastic scattering from deuterons is measured in order to determine the neutral weak currents of the nucleon. Asymmetries as small as 1 part per million in the scattering of a polarized electron beam are determined using a dedicated apparatus. It consists of specialized beam-monitoring and control systems, a cryogenic hydrogen (or deuterium) target, and a superconducting, toroidal magnetic spectrometer equipped with plastic scintillation and aerogel Cerenkov detectors, as well as fast readout electronics for the measurement of individual events. The overall design and performance of this experimental system is discussed., Comment: Submitted to Nuclear Instruments and Methods

Abstract

Abstract Background Rett syndrome is a neurodevelopmental disorder caused by a mutation in the X-linked MECP2 gene. Individuals with Rett syndrome typically develop normally until around 18 months of age before undergoing a developmental regression, and the disorder can lead to cognitive, motor, sensory, and autonomic dysfunction. Understanding the mechanism of developmental regression represents a unique challenge when viewed through a neuroscience lens. Are circuits that were previously established erased, and are new ones built to supplant old ones? One way to examine circuit-level changes is with the use of electroencephalography (EEG). Previous studies of the EEG in individuals with Rett syndrome have focused on morphological characteristics, but few have explored spectral power, including power as an index of brain function or disease severity. This study sought to determine if EEG power differs in girls with Rett syndrome and typically developing girls and among girls with Rett syndrome based on various clinical characteristics in order to better understand neural connectivity and cortical organization in individuals with this disorder. Methods Resting state EEG data were acquired from girls with Rett syndrome (n = 57) and typically developing children without Rett syndrome (n = 37). Clinical data were also collected for girls with Rett syndrome. EEG power across several brain regions in numerous frequency bands was then compared between girls with Rett syndrome and typically developing children and power in girls with Rett syndrome was compared based on these clinical measures. 1/ƒ slope was also compared between groups. Results Girls with Rett syndrome demonstrate significantly lower power in the middle frequency bands across multiple brain regions. Additionally, girls with Rett syndrome that are postregression demonstrate significantly higher power in the lower frequency delta and theta bands and a significantly more negative slope of the power spectrum. Increased power in these bands, as well as a more negative 1/ƒ slope, trended with lower cognitive assessment scores. Conclusions Increased power in lower frequency bands is consistent with previous studies demonstrating a “slowing” of the background EEG in Rett syndrome. This increase, particularly in the delta band, could represent abnormal cortical inhibition due to dysfunctional GABAergic signaling and could potentially be used as a marker of severity due to associations with more severe Rett syndrome phenotypes.

Abstract

Objectives. To assess the effects of the electromagnetic field of a Wi-Fi system and the experimental gadget M4 developed by SAS “IRDT” (France) on wheat seed germination, growth and photosynthetic activity of juvenile plants. Material and methods. The test-plants were grown under controlled conditions of light, temperature and humidity for 8 days in a pot experiment modeling the following treatments: (1) the absence of electromagnetic field of Wi-Fi systems (control); (2) at a distance of 30 cm from the operating Wi-Fi router; (3) at a distance of 30 cm from operating Wi-Fi router and the experimental gadget M4. The test plant development and vitality were assessed using indices of seed germination, growth rates (shoot height, root length, number of lateral roots, shoot and root dry weights), photosynthetic pigment content in leaves and the number of chloroploplasts per a mesophyll cell in foliar tissues. Results. It was found that the electromagnetic field of Wi-Fi router initially stimulated, but then suppressed the germination of seeds, reduced the growth of shoots and roots, the content of photosynthetic pigments and chloroplastogenesis in the mesophyll tissues in leaves of wheat juvenile plants. The root length was the most sensitive morphometric parameter to the electromagnetic field of Wi-Fi router. The use of the gadget M4 completely compensated the negative impact of Wi-Fi router on the seed germination, shoots growth, and partially compensated for the suppression of root growth, chloroplastogenesis, chlorophyll a and b content in wheat leaves. Conclusion. The attenuation effect of gadget M4 against the damaging effect of electromagnetic fields of anthropogenic origin is promising and further investigations are required to observe the effects on long term, from sowing to maturity, including the next generation of seeds.

Abstract

Pikeperch (Sander lucioperca) is a highly valuable fish in Europe. However, development of aquaculture of pikeperch is highly limited due to seasonality of production. This can be overcome by the controlled reproduction of domesticated fish. The first steps of domestication process may induce changes at anatomical, physiological and molecular levels, thereby affecting a variety of biological functions. While there is abundant literature on their effects on stress and growth for example, these effects on reproduction received limited attention notably in pikeperch, a promising candidate for the development of aquaculture. To answer the question of this life-history effect on pikeperch’s reproduction, we compared two groups (weight: 1 kg) originated from Czech Republic and with the same domestication level (F0). The first group was a recirculating aquatic system cultured one (2 years, previously fed with artificial diet, never exposed to natural changes in temperature/photoperiod conditions) and the second one was a pond cultured group (3 to 4 years, bred under natural feeding and temperature/photoperiod). The wild group successfully spawned, while the farmed one did not spawn at all. During the program, gonadosomatic indexes of both males and females were significantly higher for the wild fish, as well as the sexual steroids. Gene expression analysis revealed significantly lower LH transcript levels at the pituitary level for the farmed females and lower FSH transcript levels at the pituitary level for the males. In conclusion this study showed that the previous rearing conditions (e.g. culture system, age, diet, etc.) alter the further progress of gametogenesis and the reproductive performances in response to controlled photothermal program for both sexes in pikeperch.

Abstract

In pikeperch, Sander lucioperca, aquaculture hormonal treatment is usually applied to synchronize ovulation. However, the effect of dopamine (DA) receptor antagonists, in particular those blocking the D1 DA receptors, remains unknown. Thus, the aim of the present study was to investigate and compare the effects of D1 and D2 DA receptor antagonists on the sex-steroid production and reproductive performance of the species. Two experiments were performed during which mature pikeperch females were injected with different molecules: NaCl 0.9% (negative control) or human chorionic gonadotropin 500 IU/kg (positive control) in both experiments, metoclopramide (a D2 receptor antagonist; 4 mg/kg or 20 mg/kg) or SCH23390 (a D1 receptor antagonist; 0.8 mg/kg or 4 mg/kg) alone (experiment 1) or in combination with a salmon gonadotropin-releasing hormone analogue (sGnRHa at 25 µg/kg; experiment 2). In experiment 2, fish were also injected with sGnRHa (25 µg/kg) as positive control. Samplings of oocytes and blood were performed on the day of injection and after 24 h (both experiments), after 48 h (experiment 2) and at the time of ovulation (both experiments). In non-ovulating fish, samplings were performed 7 days (experiment 1) or 14 days (experiment 2) after injection. In experiment 2, various zootechnical parameters of fertilized eggs were recorded (survival, hatching and malformation rates). The two antagonists alone were ineffective in inducing the final stages and regulating sex-steroid (testosterone, 11 ketotestosterone, 17β estradiol and 17,20β-dihydroxy-4-pregnen-3-one) production. When administered with sGnRHa, both SCH23390 and metoclopramide induced the final stages. However, only SCH23390 stimulated testosterone (4 mg/kg) and 17β estradiol (0.8 mg/kg) production compared with sGnRHa alone. None of the treatments affected the survival, hatching or malformation rates. This is the first report suggesting that in pikeperch the D1, but not the D2, DA receptor antagonist would be involved in the testosterone and 17β estradiol production as a potentiator of the sGnRHa effect.

Abstract

Concerns about the impact of the COVID-19 pandemic on mental health have led to efforts to understand how pandemic-specific factors, such as decreased social contact during periods of social distancing, may relate to suicide risk. The present study evaluated personality-based risk factors and frequency of social contact as prospective predictors of suicidal ideation (SI) during the pandemic.We tested a relational diathesis-stress model of suicide focusing on insecure attachment, trait loneliness, and social contact as predictors of SI, using twice-weekly survey data collected via smartphone from a community sample (n = 184) over 8 weeks.Multilevel modeling showed that both trait loneliness and anxious attachment predicted the prospective development of SI during the study period. Reduced in-person contact, but not remote contact, was proximally associated with increased SI. Participants with high attachment avoidance were more likely to develop SI in the context of reduced daily in-person contact compared to participants without these traits.Findings support a relational diathesis-stress model of suicide risk during the pandemic, showing that dispositional traits related to emotional connection with others predicted the relative salience of reduced social contact as a proximal risk factor for SI.

Abstract

We report the first measurement of the (e,e′p) reaction cross-section ratios for Helium-3 (He3), Tritium (H3), and Deuterium (d). The measurement covered a missing momentum range of 40≤pmiss≤550MeV/c, at large momentum transfer (〈Q2〉≈1.9 (GeV/c)2) and xB>1, which minimized contributions from non quasi-elastic (QE) reaction mechanisms. The data is compared with plane-wave impulse approximation (PWIA) calculations using realistic spectral functions and momentum distributions. The measured and PWIA-calculated cross-section ratios for He3/d and H3/d extend to just above the typical nucleon Fermi-momentum (kF≈250 MeV/c) and differ from each other by ∼20%, while for He3/H3 they agree within the measurement accuracy of about 3%. At momenta above kF, the measured He3/H3 ratios differ from the calculation by 20%−50%. Final state interaction (FSI) calculations using the generalized Eikonal Approximation indicate that FSI should change the He3/H3 cross-section ratio for this measurement by less than 5%. If these calculations are correct, then the differences at large missing momenta between the He3/H3 experimental and calculated ratios could be due to the underlying NN interaction, and thus could provide new constraints on the previously loosely-constrained short-distance parts of the NN interaction.

The version of this article on this repository is an arXiv preprint (arXiv:2208.14575v2 [physics.ins-det] Mon, 6 Mar 2023 19:46:42 UTC (39,794 KB)) submitted to Elsevier and is not the final, peer reviewed, corrected article.

This article presents a collection of simulation studies using the ECCE detector concept in the context of the EIC's exclusive, diffractive, and tagging physics program, which aims to further explore the rich quark–gluon structure of nucleons and nuclei. To successfully execute the program, ECCE proposed to utilize the detector system close to the beamline to ensure exclusivity and tag ion beam/fragments for a particular reaction of interest. Preliminary studies confirm the proposed technology and design satisfy the requirements. The projected physics impact results are based on the projected detector performance from the simulation at 10 or 100 fb−1 of integrated luminosity. Additionally, insights related to a potential second EIC detector are documented, which could serve as a guidepost for future development.

Abstract

The Level of Personality Functioning Scale (LPFS) operationalizes Criterion A of the DSM-5 Alternative Model for Personality Disorders. Despite progress in LPFS measurement development and validation, there is a lack of research, and some disagreement, concerning structural, convergent, and incremental validity of LPFS self-report measures. The present study aimed to compare the LPFS Self-Report, LPFS Self-Report of Criterion A, and LPFS Brief Form. Internal structure was assessed through principal component analyses, factor analyses, and bifactor analyses of unidimensionality. Associations with both pathological and basic personality characteristics among the LPFS measures were explored. Incremental validity of LPFS severity in predicting pathological personality outcomes controlling for basic personality traits, and the reverse, were examined. Results suggest a unidimensional structure robustly associated with other pathological personality assessments. LPFS severity and basic personality traits mutually offered unique explanatory power. We discuss the implications of assessing personality pathology using LPFS self-report measures.

Abstract

Quantitative, empirical approaches to establishing the structure of psychopathology hold promise to improve on traditional psychiatric classification systems. The Hierarchical Taxonomy of Psychopathology (HiTOP) is a framework that summarizes the substantial and growing body of quantitative evidence on the structure of psychopathology. To achieve its aims, HiTOP must incorporate emerging research in a systematic, ongoing fashion. In this paper, we introduce the conceptual background, organizing principles, core assumptions, and procedures for revising the HiTOP framework. Informed by strengths and shortcomings of previous classification systems, the proposed revisions protocol is a formalized system focused around three pillars: 1) prioritizing systematic evaluation of quantitative evidence by a set of transparent criteria and processes, 2) balancing stability with flexibility, and 3) promoting inclusion over gatekeeping in all aspects of the process. We detail how the revisions protocol will be applied in practice, including the scientific and administrative aspects of the process. Additionally, we describe areas of the HiTOP structure that will be a focus of early revisions and outline challenges for the revisions protocol moving forward. The proposed revisions protocol will ensure that the HiTOP framework reflects the current state of scientific knowledge on the structure of psychopathology and fulfills its potential to advance clinical research and practice.

Abstract

We performed feasibility studies for various single transverse spin measurements that are related to the Sivers effect, transversity and the tensor charge, and the Collins fragmentation function. The processes studied include semi-inclusive deep inelastic scattering (SIDIS) where single hadrons (pions and kaons) were detected in addition to the scattered DIS lepton. The data were obtained in {\sc pythia}6 and {\sc geant}4 simulated e+p collisions at 18 GeV on 275 GeV, 18 on 100, 10 on 100, and 5 on 41 that use the ECCE detector configuration. Typical DIS kinematics were selected, most notably $Q^2 > 1 $ GeV$^2$, and cover the $x$ range from $10^{-4}$ to $1$. The single spin asymmetries were extracted as a function of $x$ and $Q^2$, as well as the semi-inclusive variables $z$, and $P_T$. They are obtained in azimuthal moments in combinations of the azimuthal angles of the hadron transverse momentum and transverse spin of the nucleon relative to the lepton scattering plane. The initially unpolarized MonteCarlo was re-weighted in the true kinematic variables, hadron types and parton flavors based on global fits of fixed target SIDIS experiments and $e^+e^-$ annihilation data. The expected statistical precision of such measurements is extrapolated to 10 fb$^{-1}$ and potential systematic uncertainties are approximated given the deviations between true and reconstructed yields. The impact on the knowledge of the Sivers functions, transversity and tensor charges, and the Collins function has then been evaluated in the same phenomenological extractions as in the Yellow Report. The impact is found to be comparable to that obtained with the parameterized Yellow Report detector and shows that the ECCE detector configuration can fulfill the physics goals on these quantities., 22 pages, 22 figures, to be submitted to joint ECCE proposal NIM-A volume

21. Comparing Measures of Criterion A to Better Understand Incremental Validity in the Alternative Model of Personality Disorders

Abstract

The Alternative Model of Personality Disorders distinguishes between the severity of personality dysfunction (Criterion A) and individual differences in personality disorder expression (Criterion B). Several Criterion A measures exist, but few studies have compared these measures with each other. Moreover, debates about whether the constructs of Criteria A and B are redundant (i.e., weak incremental validity) should be framed around how different Criterion A measures perform relative to others. This study of 204 undergraduate students evaluated multiple measures of Criterion A. These measures were strongly correlated with Criterion B, but evidenced incremental validity (39% of outcomes, 5% average additional variance explained) with outcomes of psychopathology and interpersonal impairments, and less consistent incremental validity with suicidality, aggression, and mental health utilization. We discuss how these results inform the construct of Criterion A relative to Criterion B and evaluate strengths/weaknesses of Criterion A measures.

Abstract

We present a simple framework in which both the exchange rates disconnect and forward bias puzzles are simultaneously resolved. The flexible-price two-country monetary model is extended to include a consumption externality with habit persistence. Habit persistence is modeled using Campbell Cochrane preferences with „deep‟ habits. By deep habits, we mean habits defined over goods rather than countries. The model is simulated using the artificial economy methodology. It offers a neo-classical explanation of the Meese-Rogoff puzzle and mimics the failure of fundamentals to explain nominal exchange rates in a linear setting. Finally, the model naturally generates the negative slope in the standard forward market regression.

Abstract

Injuries to the triangular fibrocartilage complex (TFCC) and distal radioulnar joint (DRUJ) require careful consideration and management to ensure an optimal outcome. These complex injuries can be effectively managed by having a fundamental understanding of the anatomy of the structures involved in addition to an appreciation of the biomechanical modes of failure in the context of wrist trauma. The principles of managing these injuries are addressed in this article by focusing on the relevant anatomy and highlighting the key features of clinical and radiological assessment. An outline of the surgical treatment options is included to help the clinician select the most appropriate treatment ranging from soft tissue repair to salvage measures.

Abstract

To address gaps in knowledge and to tackle complex social–ecological problems, scientific research is moving toward studies that integrate multiple disciplines and ways of knowing to explore all parts of a system. Yet, how these efforts are being measured and how they are deemed successful is an up-and-coming and pertinent conversation within interdisciplinary research spheres. Using a grounded theory approach, this study addresses how members of a sustainability science-focused team at a Northeastern U.S. university funded by a large, National Science Foundation (NSF) grant contend with deeply normative dimensions of interdisciplinary research team success. Based on semi-structured interviews (N = 24) with researchers (e.g., faculty and graduate students) involved in this expansive, interdisciplinary team, this study uses participants’ narrative accounts to progress our understanding of success on sustainability science teams and addresses the tensions arising between differing visions of success present within the current literature, and perpetuated by U.S. funding agencies like NSF. Study findings reveal that team members are forming definitions of interdisciplinary success that both align with, and depart from, those appearing in the literature. More specifically, some respondents’ notions of team success appear to mirror currently recognized outcomes in traditional academic settings (i.e., purpose driven outcomes—citations, receipt of grant funding, etc.). At the same time, just as many other respondents describe success as involving elements of collaborative research not traditionally acknowledged as a forms of “success” in their own right (i.e., capacity building processes and outcomes—relationship formation, deep understandings of distinct epistemologies, etc.). Study results contribute to more open and informed discussions about how we gauge success within sustainability science collaborations, forming a foundation for appreciation and exploration of the disciplinary and normative dimensions of this work.

Abstract

Exclusive heavy quarkonium photoproduction is one of the most popular processes in EIC, which has a large cross section and a simple final state. Due to the gluonic nature of the exchange Pomeron, this process can be related to the gluon distributions in the nucleus. The momentum transfer dependence of this process is sensitive to the interaction sites, which provides a powerful tool to probe the spatial distribution of gluons in the nucleus. Recently the problem of the origin of hadron mass has received lots of attention in determining the anomaly contribution $M_{a}$. The trace anomaly is sensitive to the gluon condensate, and exclusive production of quarkonia such as J/$\psi$ and $\Upsilon$ can serve as a sensitive probe to constrain it. In this paper, we present the performance of the ECCE detector for exclusive J/$\psi$ detection and the capability of this process to investigate the above physics opportunities with ECCE., Comment: 11 pages, 14 figures, 1 table

Abstract

The Electron-Ion Collider (EIC) is a cutting-edge accelerator facility that will study the nature of the "glue" that binds the building blocks of the visible matter in the universe. The proposed experiment will be realized at Brookhaven National Laboratory in approximately 10 years from now, with detector design and R&D currently ongoing. Notably, EIC is one of the first large-scale facilities to leverage Artificial Intelligence (AI) already starting from the design and R&D phases. The EIC Comprehensive Chromodynamics Experiment (ECCE) is a consortium that proposed a detector design based on a 1.5T solenoid. The EIC detector proposal review concluded that the ECCE design will serve as the reference design for an EIC detector. Herein we describe a comprehensive optimization of the ECCE tracker using AI. The work required a complex parametrization of the simulated detector system. Our approach dealt with an optimization problem in a multidimensional design space driven by multiple objectives that encode the detector performance, while satisfying several mechanical constraints. We describe our strategy and show results obtained for the ECCE tracking system. The AI-assisted design is agnostic to the simulation framework and can be extended to other sub-detectors or to a system of sub-detectors to further optimize the performance of the EIC detector., 16 pages, 18 figures, 2 appendices, 3 tables

Abstract

Aims To systematically review randomised control trials (RCT’s) assessing the effectiveness and safety of surgical interventions in adults with plantar fasciopathy (PF). Materials and methods We searched MEDLINE, EMBASE, Web of Science, Google Scholar, the Cochrane Central Register of Controlled Trials, trial registries and references lists. RCT’s comparing surgical interventions with non-surgical or surgical comparisons in adults with PF were included. Primary outcomes were changes in first step pain severity/intensity, and incidence/nature of adverse events. Secondary outcomes included foot and ankle related disability/function, health related quality of life, cost effectiveness, changes in other reported measures of pain and medication use. Data were extracted at short-term (≤3 months post-intervention), medium-term (>3months—≤6 months post-intervention) or long-term (>6 months—≤2 years post-treatment). Certainty of evidence was evaluated using the modified Grading of Recommendations Assessment, Development and Evaluation (GRADE). Results From 3620 screened records, we included 8 studies comprising 345 patients. Substantial variation across trials precluded meta-analysis, hence a narrative synthesis was conducted. We judged all studies to have high risk of bias. For all outcome comparisons our GRADE judgement for the certainty of the evidence was very low. Three studies compared one type of surgery with another largely showing little to no difference in outcomes for pain, function or quality of life. Five studies compared surgery with non-surgical interventions—three providing very low certainty evidence that surgery may improve pain and function at long-term follow-up compared to non-surgical comparisons, whereas two studies provided no long-term between-group differences. Reporting of adverse events were inadequate, inconsistent or absent across all studies. Conclusion There is a paucity of high certainty evidence to support or refute the effectiveness and safety of surgical interventions in the management of PF. We make recommendations for improving the evidence base in this field.

Abstract

The impact of reduced social contact on mental health during the COVID-19 pandemic has been identified as a major public health concern. While personality factors such as attachment style have been associated with psychological distress during the pandemic, the longitudinal relevance of these factors and the role of daily social contact in mitigating distress remains poorly understood. This study evaluated the impact of social contact and attachment style on changes in loneliness over an 8-week experience sampling period during the COVID-19 pandemic. A general adult sample (n=184) recruited online completed measures of psychological distress, attachment, and loneliness via smartphone. Loneliness and daily social contact were assessed twice per week for eight weeks, yielding 1,124 unique observations. During the experience sampling period, proximal increases in loneliness were associated with decreased daily in-person contact. In contrast, participants who described themselves as having fewer interactions via text, phone, or videoconferencing, as well as those with higher anxious and avoidant attachment traits, reported greater experiences of loneliness over time. These findings suggest the relevance of both enduring personality characteristics and daily social behaviors as risk factors for loneliness during the pandemic, pointing to potential targets for clinical intervention and future empirical study.

Abstract

Introduction. Concerns about the impact of the COVID-19 pandemic on mental health have led to efforts to understand how pandemic-specific factors, such as decreased social contact during periods of social distancing, may relate to suicide risk. The present study evaluated personality-based risk factors and frequency of social contact as prospective predictors of suicidal ideation (SI) during the pandemic. Methods. We tested a relational diathesis-stress model of suicide focusing on insecure attachment, trait loneliness, and social contact as predictors of SI, using twice-weekly survey data collected via smartphone from a community sample (n=184) over eight weeks. Results. Multilevel modeling showed that both trait loneliness and anxious attachment predicted the prospective development of SI during the study period. Reduced in-person contact, but not remote contact, was proximally associated with increased SI. Participants with low attachment anxiety, high attachment avoidance, and high trait loneliness were more likely to develop SI in the context of reduced daily in-person contact compared to participants without these traits. Conclusion. Findings support a relational diathesis-stress model of suicide risk during the pandemic, showing that dispositional traits related to emotional connection with others predicted the relative salience of reduced social contact as a proximal risk factor for SI.

Abstract

The ratio of the nucleon F_{2} structure functions, F_{2}^{n}/F_{2}^{p}, is determined by the MARATHON experiment from measurements of deep inelastic scattering of electrons from ^{3}H and ^{3}He nuclei. The experiment was performed in the Hall A Facility of Jefferson Lab using two high-resolution spectrometers for electron detection, and a cryogenic target system which included a low-activity tritium cell. The data analysis used a novel technique exploiting the mirror symmetry of the two nuclei, which essentially eliminates many theoretical uncertainties in the extraction of the ratio. The results, which cover the Bjorken scaling variable range 0.19x0.83, represent a significant improvement compared to previous SLAC and Jefferson Lab measurements for the ratio. They are compared to recent theoretical calculations and empirical determinations of the F_{2}^{n}/F_{2}^{p} ratio.

Abstract

Anterior shoulder dislocation is a common condition that most orthopaedic surgeons will have to deal with in their practice. Nonoperative management of the initial traumatic anterior shoulder dislocation is likely to lead to a recurrent shoulder dislocation in more than 90% of cases in the younger active population. Recurrent anterior shoulder dislocation can persist even after instability surgery in certain cases. A detailed, accurate assessment of the patient is of paramount importance for successful treatment. This review aims to provide insight into key concepts to consider in the assessment of an anterior shoulder dislocation. Predisposing factors, clinical examination and the role of imaging in the assessment of an anterior shoulder dislocation will be reviewed. Level of evidence: Level 5

Abstract

When protons and neutrons (nucleons) are bound into atomic nuclei, they are close enough to feel significant attraction, or repulsion, from the strong, short-distance part of the nucleon-nucleon interaction. These strong interactions lead to hard collisions between nucleons, generating pairs of highly energetic nucleons referred to as short-range correlations (SRCs). SRCs are an important but relatively poorly understood part of nuclear structure

Abstract

We report measurements of the exclusive neutral pion electroproduction cross section off protons at large values of $x_B$ (0.36, 0.48 and 0.60) and $Q^2$ (3.1 to 8.4 GeV$^2$) obtained from Jefferson Lab Hall A experiment E12-06-014. The corresponding structure functions $d\sigma_L/dt+\epsilon d\sigma_T/dt$, $d\sigma_{TT}/dt$, $d\sigma_{LT}/dt$ and $d\sigma_{LT'}/dt$ are extracted as a function of the proton momentum transfer $t-t_{min}$. The results suggest the amplitude for transversely polarized virtual photons continues to dominate the cross-section throughout this kinematic range. The data are well described by calculations based on transversity Generalized Parton Distributions coupled to a helicity flip Distribution Amplitude of the pion, thus providing a unique way to probe the structure of the nucleon.

Abstract

We report measurements of the parity-conserving beam-normal single-spin elastic scattering asymmetries $B_n$ on $^{12}$C and $^{27}$Al, obtained with an electron beam polarized transverse to its momentum direction. These measurements add an additional kinematic point to a series of previous measurements of $B_n$ on $^{12}$C and provide a first measurement on $^{27}$Al. The experiment utilized the Qweak apparatus at Jefferson Lab with a beam energy of 1.158 GeV. The average lab scattering angle for both targets was 7.7 degrees, and the average $Q^2$ for both targets was 0.02437 GeV$^2$ (Q=0.1561 GeV). The asymmetries are $B_n$ = -10.68 $\pm$ 0.90 stat) $\pm$ 0.57 (syst) ppm for $^{12}$C and $B_n$ = -12.16 $\pm$ 0.58 (stat) $\pm$ 0.62 (syst) ppm for $^{27}$Al. The results are consistent with theoretical predictions, and are compared to existing data. When scaled by Z/A, the Q-dependence of all the far-forward angle (theta < 10 degrees) data from $^{1}$H to $^{27}$Al can be described by the same slope out to $Q \approx 0.35$ GeV. Larger-angle data from other experiments in the same Q range are consistent with a slope about twice as steep.

Abstract

Determining optimal conditions for the production of well diffracting crystals is a key step in every biocrystallography project. Here, a microfluidic device is described that enables the production of crystals by counter-diffusion and their direct on-chip analysis by serial crystallography at room temperature. Nine 'non-model' and diverse biomacromolecules, including seven soluble proteins, a membrane protein and an RNA duplex, were crystallized and treated on-chip with a variety of standard techniques including micro-seeding, crystal soaking with ligands and crystal detection by fluorescence. Furthermore, the crystal structures of four proteins and an RNA were determined based on serial data collected on four synchrotron beamlines, demonstrating the general applicability of this multipurpose chip concept., The following funding is acknowledged: Agence Nationale de la Recherche (contract No. ANR-11-LABX-0057_MITOCROSS to Claude Sauter, Bernard Lorber; contract No. ANR-10-LABX-0036_NETRN to Claude Sauter, Bernard Lorber; contract No. ANR-13-BS07-0007-01 to Eric Girard, Sylvain Engilberge); Ministère des Affaires Etrangères (contract No. PROCOPE Hubert Curien to Claude Sauter, Mario Mörl); Deutsche Forschungsgemeinschaft (contract No. Mo 634/10-1 to Mario Mörl, Heike Betat); Université de Strasbourg [grant No. Initiative d'excellence (IDEX) to Claude Sauter, Raphaël de Wijn]; Centre National de la Recherche Scientifique (grant No. MRCT-2012_PTI_UPR9002 to Claude Sauter).

Abstract

The present research case sought to illustrate how self-regulatory patterns of interpersonal behavior manifest within a rejection sensitive individual at the daily level. Cross-sectional research has demonstrated negative relational outcomes associated with rejection sensitivity, but less attention has been paid to how this manifests in daily relational events. Expanding upon prior research evaluating the daily interpersonal functioning of those with high rejection sensitivity in a large sample, the research case study of Mary demonstrates how findings from research may manifest within a rejection sensitive individual who was asked to rate her interpersonal events over the course of a week. For Mary, covariations among her interpersonal perceptions suggest a negativity bias that may be basis of a self-fulfilling prophecy, in which her rejection expectancies come to be realized through her treating agency as unfriendly behavior. The implications for psychotherapy of interpersonal patterns typically observed in rejection sensitive clients are discussed.

Abstract

Introduction Dried blood spot (DBS) sample applications now encompass analytes related to clinical diagnosis, epidemiological studies, therapeutic drug monitoring, pharmacokinetic and toxicokinetic studies. Haematocrit (Hct) and haemoglobin (Hb) at very high or low concentrations may influence the accuracy of measurement quantification of the DBS sample. In this study, we aimed to predict the Hct of the punched DBS through primary spectrophotometric estimation of its haemoglobin-derivative (Hb-drv) content. Methods Formic acid solution was used to elute Hb-drv content of 3.2 mm spotted blood from its dry matrix. Direct spectrometry measurement was utilised to scan the extracted Hb-drv in the visible spectrum range of 520–600 nm. The linear relationship between an individual’s Hct percentage and Hb-drv concentration was applied to estimate the Hct level of the blood spot. De-identified whole blood samples were used for the method development and evaluation studies. Results The Hb-drv estimation is valid in samples >2 months old. Method validation experiments DBS demonstrate linearity between 82.5 and 207.5 g/L, average coefficient of variation of 3.6% (intra-assay) and 7.7% (inter-assay), analytical recovery of 84%, and a high positive correlation (r=0.88) between Hb-drv and the original whole blood Hct. The Bland-Altman difference plot demonstrates a mean difference of 2.4% between the calculated DBS Hct and the directly measured Hct from fresh whole bloods. Conclusions We have successfully developed a simple Hb-drv method to estimate Hct in aged DBS samples. This method can be incorporated into DBS analytical work-flow for the in-situ estimation of Hct and subsequent correction of the analyte of interest as required.
