Prediction of the electromagnetic torque in synchronous machines through Maxwell stress harmonic filter (HFT) method [PDF]
, 2006 For the calculation of torque in synchronous motors a local method is analysed, based on the Maxwell stress theory and the filtered contributions due to the harmonics of the magnetic vector potential in the motor air-gap.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A lightweight hybrid backpack integrating SC‐TENGs and R‐EMGs harvests biomechanical energy during walking. With a low activation speed of 3 km h−1 and a high specific power of 0.18 W kg−1, it enables self‐powered field safety management. The power backpack refers to an energy‐harvesting solution engineered to mitigate battery reliance in wearable ...

Active cogging torque construction by the weld slot design in a positioning servo system
IET Electric Power ApplicationsThe cogging torque is usually considered as an adverse effect of the PM machine servo system. This paper presents a new perspective that the cogging torque can be exploited in many practical situations as long as the speed ripple can be suppressed.

Grassland Research, EarlyView.Plant species richness was greater in summer in both alpine and subalpine grassland ecosystems. Soil moisture demonstrates significant positive correlations with soil organic carbon and total nitrogen across seasonal periods. Microbial α‐diversity peaks during summer but maintains functional stability across seasons.

The importance of gene polymorphism in familial inheritance of endometriosis
International Journal of Gynecology &Obstetrics, EarlyView.Abstract Objective The study aimed to investigate familial transmission patterns in women with endometriosis by generating a customized single‐nucleotide polymorphism (SNP) array. Methods Patients aged 18–45 who were diagnosed histopathologically with endometriosis were included in the study.

Interdisciplinary Medicine, EarlyView.Integrated multi‐omics reveals that CD36‐mediated lipid overload in PBMCs drives T cell exhaustion via sub‐lethal ferroptotic stress and AKT suppression. This systemic metabolic signature serves as a robust predictor of immunotherapy response in HCC, suggesting that modulating lipid metabolism can rescue immune fitness.
