Design of PM Linear Synchronous Motor With Chamfered Teeth for Reduced Detent Force Considering Modular Connection

IEEE Access
This paper presents the design of the detent force reduction in the chamfered tooth permanent magnet linear synchronous motor (PMLSM). In PMLSMs, in addition to the cogging force characteristic, there is an additional end force at the longitudinal end ...

Skin Shade Discrimination Is Associated With Disordered Weight Control Behaviors in Hong Kong, Malaysia, Singapore, and Thailand

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Emerging evidence indicates that experiencing discrimination is associated with disordered eating. This study aimed to test the association between experiences of colorism (skin shade discrimination penalizing those with darker skin) and the prevalence of disordered weight control behaviors (DWCBs) in four Asian countries/regions ...

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, Volume 600, Issue 10, Page 1444-1474, May 2026.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Hierarchical Artificial Muscle with Nonlinear Elasticity for Antagonistic and Cyclic Robotics

Advanced Science, Volume 13, Issue 30, 28 May 2026.
We construct hierarchical muscles by plying nylon fibers around a heating wire. The hierarchical muscle shows a J‐shaped passive curve, which shows benefit in antagonistic muscle pair and work accumulation mechanism. We also develop a computational, first‐principle model to understand the physics of both active actuation stroke and passive J‐curve ...

Practitioner Review: Clinical insights from attachment theory and research for professionals working with young children and their families

Journal of Child Psychology and Psychiatry, Volume 67, Issue 5, Page 723-739, May 2026.
Attachment theory, with its core concepts, perspectives, and insights developed over the past five decades, is influential for professionals working with young children. However, practitioners face challenges translating attachment theory and research into practical applications.

Development of a Grasshopper‐Leg‐Inspired Back‐Type Exoskeleton for the Reduction of Muscle Activation During Stoop Activities

Journal of Field Robotics, Volume 43, Issue 2, Page 739-760, March 2026.
ABSTRACT Farmers frequently suffer from musculoskeletal disorders, particularly lower back pain (LBP), mainly due to occupational ergonomic factors such as repetitive stooping and lifting. This study proposes using an exoskeleton to reduce LBP risk by providing external torque to the hip joints.

Reversal‐Halbach PM Array Design to Suppress Thrust Ripple of a Linear Primary PM Vernier Machine

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel reverse Halbach array‐based LPPMVM (RH‐LPPMVM), which weakens the amplitudes of armature flux density harmonics in the air gap through reverse excitation of Halbach PMs and permeance phase shift, thereby reducing the thrust ripple. The dominant role of electromagnetic force fluctuations is determined, and the harmonic orders
