In this manuscript, the graphite/resin composite plates were prepared via a facile ball milling strategy. The needle coke (NC) as a conductive additive was studied on effects of treated by ball milling on the electrical conductivity, mechanical property of the composite plates. All the characterizations showed that after ball milling, the NC particles have smaller particle size, and more uniform particle size distribution, which enhanced the interfacial adhesion between particles and resin. Due to the difference in shape and size between the auxiliary conductive filler and flake graphite, the addition of NC particles can easily fill the gap between flake‐like graphite and phenolic resin. The uniform distribution of these fillers improves the cross‐linking density, and the conductive path was added between the flake‐like graphite and the resin, which improved the electric conductivity of composit plate from 26.32 S cm−1 to 149.23 S cm−1. Such a prominent performance was attributed to the synergistic effects between the uniformly incorporated NC and the graphite/resin composite adhesive system. [ABSTRACT FROM AUTHOR]

During transient process, it may take plenty of steps for PMSM to reach the reference torque and flux linkage. Multistep model predictive torque and flux control (MPTC) can select the best sequence of voltage vectors from the initial state to the reference state to achieve the fastest torque response. However, the computation burden is a significant challenge for real-time implementation. This paper proposes a novel fast-response MPTC strategy for PMSM drives. The reference torque is converted to flux linkage in d-axis and q-axis to eliminate the weighting factor in cost function. During the transient process, Pontryagin's maximum principle is used to design minimum-time flux linkage trajectories from the initial state to the reference state. In each control period, along the reference flux linkage trajectories, one-step MPTC is used to select the best voltage vector. The computational burden and dynamic performance of the proposed method are verified by experiments. [ABSTRACT FROM AUTHOR]

To achieve precise voltage value for modern model-based motor control strategies, an accurate voltage distortion compensation method for voltage source inverters is proposed in this paper. The voltage distortion principles of a mosfet-based inverter and an IGBT-based inverter are analyzed and compared. A graphical solution of compensating voltage error is proposed, all the voltage distortion factors are considered. A current observer is designed to overcome time delay, achieve precise current in each switching period for compensation. The proposed method is of high precision, intuitive, and easy to implement. The effectiveness of the proposed method is verified by experiments. [ABSTRACT FROM PUBLISHER]

This paper proposes an alternative strategy of finite-control-set model-predictive torque control (MPTC) to reduce the computational burden and the torque ripple and decouple the switching frequency from the controller sampling time. An improved discrete space-vector modulation (DSVM) technique is utilized to synthesize a large number of virtual voltage vectors. The deadbeat (DB) technique is used to optimize the voltage vector selection process, avoiding enumerating all the feasible voltage vectors. With this proposed method, only three voltage vectors are tested in each predictive step. Based on the improved DSVM method, the three candidate voltage vectors are calculated by using a novel algebraic way. This new strategy has the benefits of both the MPTC method and the DB method. The effectiveness of the proposed strategy is validated based on a test bench. [ABSTRACT FROM PUBLISHER]

This paper proposes a dynamic optimization strategy of finite control set-model predictive torque control for permanent magnet synchronous machines, which takes into account the inverter losses and machine losses simultaneously. In order to reduce the switching losses (or to optimize the switching sequence) of the inverter, a recognized and feasible constrain which considers the accumulated ON/OFF times of the switches is implemented. The machine losses are taken into account by utilizing an optimal stator flux reference. An alternative loss model control method is proposed to calculate the optimal stator flux reference, which combines the conventional maximum torque/ampere method and the conventional loss model control method. Furthermore, a discrete-time machine model is introduced, which can reduce the predictive error at relative low switching frequency. The key results are illustrated by a combination of simulation and prototype interior permanent magnet machine drive measurements. [ABSTRACT FROM AUTHOR]

This paper proposes a control strategy of finite-control-set model predictive torque control (FCS-MPTC) with a deadbeat (DB) solution for permanent-magnet synchronous motor drives. By using a DB solution, the process of selection of the best switching vector is optimized. The predicted DB voltage sector consisting of the desired voltage vector (VV) avoids the complete enumeration for testing all feasible VVs, which relieves the big calculation effort of the traditional FCS-MPTC method. The proposed system is experimentally carried out both in the steady state and in the transient state. [ABSTRACT FROM PUBLISHER]

This paper introduces two different novel designs of interior permanent-magnet synchronous machines with concentrated windings, which are attractive to a self-sensing control system. The new machines have some advantages: lower subharmonics of air-gap flux density and magnetomotive force and lower machine losses, including eddy current losses. The machines have been adapted for self-sensing applications by using a high-frequency (HF) injection method. The main machine parameters affecting the estimation accuracy are analyzed such as fundamental frequency saliencies, cross saturation, HF inductance, HF resistance, and harmonic distortion due to multisaliencies. The experimental results verify that the novel machines can reach very high performance with good self-sensing properties regarding the accuracy of the estimated position/speed of electric drives even without the multisaliency decoupling compensation method.

• One-dimensional vortex-arrays with singularity tuned from 1 to 4 have been achieved. • Four-singularity vortex-array with peak power of 5.56 kW has been achieved. • A method for developing pulsed one-dimensional vortex-array with tunable singularity. One-dimensional (1D) vortex-arrays with multiple-singularity aligning along a line are flexible for microparticle manipulation, high capacity storage, material processing. Moreover, a high peak power one-dimensional vortex-array with large singularity enables assemble processing. The development of a miniature laser to directly generate one-dimensional vortex-array with tunable singularity is of great value for practical applications. However, solid-state lasers for this purpose was limited by the low power, low efficiency and less singularity achieved. Here, we demonstrate a simple and robust method for directly generating one-dimensional vortex-array with singularity tunable upon to 4 in a tilted Nd:YAG/Cr4+:YAG composite crystal passively Q-switched (PQS) microchip laser, irradiated by a decentered annular beam (DAB). The singularity of one-dimensional vortex-array can be tuned from 1 to 4 by controlling the offset of collimating lens, Δ x. The average output power of one-dimensional vortex-array with 4 singularities is 0.76 W at P in = 5.66 W, the optical conversion efficiency is 13.4%. One-dimensional vortex-array with 4 singularities processes pulse width of 3.5 ns, peak power of 5.56 kW. The achieved results suggest the potential that DAB can be used a practical pump beam in PQS microchip laser for generating nanosecond, high peak power one-dimensional vortex-arrays with tunable singularity.

Highly active Pt‐based intermetallic nanoparticles (i‐NPs) loaded on stable supports have garnered considerable interest as promising oxygen reduction reaction (ORR) catalysts for proton‐exchange‐membrane fuel cells (PEMFCs). Herein, thermostable tellurium (Te) is vapor‐deposited onto commercial conductive carbon to anchor high‐temperature‐synthesized Pt3Co i‐NPs. Advanced characterization and density functional theory (DFT) calculations demonstrate that the binding energy of Pt 4f and Co 2p shift positively by 0.12 and 0.95 eV after the introduction of Te in carbon support, promoting the formation of Pt─Te bonds, which enhances the metal–support interactions (MSIs) in Pt3Co/Te‐C (with a more negative binding energy of −10.28 eV). The average size of well‐dispersed Pt3Co i‐NPs (≈3.9 nm) on Te─C is considerably smaller than that of Pt3Co i‐NPs (≈9.1 nm) on commercial carbon. The specific activity of Pt3Co/Te‐C decreases by only 1.5% after 100,000 ultra‐long voltage‐accelerated cycles, while the morphology remains almost unchanged. The membrane electrode assembly using Pt3Co/Te‐C as a cathode demonstrates impressive activity (power density of 2.32 W cm−2@4 A cm−2 and mass activity of 0.50 A mgPt−1@0.9 V) and robust durability (mass activity@0.9 V loss of 26% after 30,000 cycles with intact L12 ordered structure) in H2–O2 operation, significantly exceeding the DOE 2025 requirements.

This research aims to correlate the macroscopic fracture phenomenon with its microscopic fracture mechanism for an advanced high-strength steel (AHSS) TRIP 780 sheet by applying a combined experimental-numerical approach. Six specimens with different shapes were tensioned to fracture and the main deformation areas of specimens were subjected to stress states ranging from lower to higher stress triaxiality. The final fracture surface feature for each specimen was obtained to characterize the macroscopic fracture modes at different stress states. The scanning electron microscope (SEM) fractographies of fracture surfaces were detected to reveal the microscopic fracture mechanisms. The stress triaxiality evolution was applied to correlate of fracture mode and fracture mechanism by comparing the macroscopic fracture features as well as micro-defect changes. An increase of stress triaxiality leads to voids extension and then results in a voids-dominant fracture. The micro-shear-slip tends to appear in the stress triaxiality level lower than that of pure shear stress state. The fracture behavior of a practice deformation process was the result of interplay between shear-slip fracture and void-dominant fracture. The unified relationship between average void sizes and stress triaxiality was obtained. The void growth was predicted by the Rice–Tracey model with higher precision. [ABSTRACT FROM AUTHOR]

For salient-pole permanent magnet synchronous motor (PMSM), the amplitude of extended back electromotive force (EEMF) is determined by rotor speed, stator current and its derivative value. Theoretically, even at extremely low speed, the back EEMF can be detected if the current in q-axis is changing. However, it is difficult to detect the EEMF precisely due to the current at low speed. In this paper, novel full-order multi-input and multi-output discrete-time sliding mode observer (SMO) is built to detect the rotor position. With the proposed rotor position estimation technique, the motor can start up from standstill and reverse between positive and negative directions without a position sensor. The proposed method was evaluated by experiment. [ABSTRACT FROM AUTHOR]

In this work, a mesoporous zinc oxide containing different concentrations of oxygen vacancies (V O) was controlled synthesized via low temperature annealing. XPS, Raman spectroscopy and electron paramagnetic resonance spectroscopy were employed to investigate the changes of V O concentrations following the increase of annealing temperature. According to the experiment, the highest concentration of V O was obtained at the annealing temperature of 350 °C. The relationship between photoelectrochemical biosensor performance and V O concentration was discussed in detail in terms of electrochemical measurements and V O characterization. Results showed that increasing the V O could result in high carrier intensity, active sites and catalytic rate constant. In addition, the performance toward glucose detection could be improved by increasing V O. [ABSTRACT FROM AUTHOR]

Urban greenways (UGW) are increasingly recognized as vital components of urban green infrastructure (UGI). While existing research has provided empirical evidence on the positive impacts of UGW on physical health, studies focusing on the effects on mental health remain limited. Moreover, previous investigations predominantly compare UGW as a whole with other built environments, neglecting the influence of specific vegetation designs along UGW on mental health. To address this research gap, we conducted a randomized controlled experiment to examine the impact of vegetation design along UGW on stress reduction and attention restoration. A total of 94 participants were randomly assigned to one of four UGW conditions: grassland, shrubs, grassland and trees, or shrubs and trees. Utilizing immersive virtual reality (VR) technology, participants experienced UGW through a 5-min video presentation. We measured participants' subjective and objective stress levels and attentional functioning at three time-points: baseline, pre-video watching, and post-video watching. The experimental procedure lasted approximately 40 minutes. Results of the repeated-measures ANOVA revealed that participants experienced increased stress and mental fatigue after the stressor and decreased levels following the UGW intervention. Furthermore, between-group analyses demonstrated that the shrubs group and the grassland and trees group exhibited significantly greater stress reduction than the grassland group. However, there are no significant differences in attention restoration effects between the four groups. In conclusion, virtual exposure to UGW featuring vegetation on both sides positively affected stress reduction and attention restoration. It is recommended that future UGW construction incorporates diverse vegetation designs, including shrubs or trees, instead of solely relying on grassland. More research is needed to explore the combined effects of shrubs and trees on mental health outcomes., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Jiang, Wang, He, Gu, Wei, Xu and Sullivan.)

There is an ongoing debate concerning the performance of salvaged allogeneic hematopoietic stem cell transplantation (allo-HSCT) in pediatric patients with acute refractory leukemia, in whom the prognosis is quite dismal. Few studies have ever been conducted on this subject. This may be partly due to missed opportunities by majority of the patients in such situations. To investigate the feasibility, evaluate the efficiency, and identify the prognostic factors of allo-HSCT in this sub-setting, the authors performed a single institution-based retrospective analysis. A total of 44 patients, of whom 28 had acute myeloid leukemia (AML), 13 had acute lymphocytic leukemia (ALL), and 3 had mixed phenotype leukemia (MPL), were enrolled in this study. With a median follow-up of 19 months, the estimated 2-year overall survival (OS) and progression free survival (PFS) were 34.3% (95% CI, 17.9-51.4%) and 33.6% (95% CI, 18.0-50.1%), respectively. The estimated 2-year incidence rates of relapse and non-relapse mortality (NRM) were 43.8% (95% CI 26.4-60.0%) and 19.6% (95% CI 9.1-32.9%), respectively. The estimated 100-day cumulative incidence of acute graft versus host disease (aGvHD) was 43.6% (95% CI 28.7-57.5%), and the 1-year cumulative incidence of chronic GvHD (cGvHD) was 45.5% (95% CI 30.5-59.3%). Compared with the previous studies, the multivariate analysis in this study additionally identified that female donors and cGvHD were associated with lower relapse and better PFS and OS. Male recipients, age younger than 10 years, a diagnosis of ALL, and the intermediate-adverse cytogenetic risk group were associated with increased relapse. On the contrary, extramedullary disease (EMD) and aGvHD were only linked to worse PFS. These data suggested that although only one-third of the patients would obtain PFS over 2 years, salvaged allo-HSCT is still the most reliable and best therapeutic strategy for refractory pediatric acute leukemia. If probable, choosing a female donor, better management of aGvHD, and induction of cGvHD promotes patient survival., Competing Interests: CONFLICTS OF INTEREST The authors disclose no conflicts of interest.
