Cogging Torque Reduction in Permanent Magnet Machines [PDF]
IEEE Transactions on Industry Applications, 2006 This paper examines two methods - magnet shifting and optimizing the magnet pole arc - for reducing cogging torque in permanent magnet machines. The methods were applied to existing machine designs and their performance was calculated using finite-element analysis (FEA).

Journal of Field Robotics, EarlyView.ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.

Clinical Case Reports, Volume 14, Issue 8, August 2026.ABSTRACT Paratesticular rhabdomyosarcoma is a rare malignancy in children and adolescents that frequently presents diagnostic challenges when mimicking benign inflammatory conditions. We report the case of a 14‐year‐old previously healthy male who presented with acute right scrotal pain and swelling initially diagnosed as epididymo‐orchitis.

Advanced Sensor Research, Volume 5, Issue 7, July 2026.A coil‐based soft sensor is presented for auto‐adaptive control of bioinspired dry adhesive robotic end‐effectors. The sensor enables misalignment detection during continuous motion and discriminates planar and convex surface geometries. Integrated into activated adhesive structures, the system achieves high angular accuracy and robust object ...

Embryonal Paratesticular Rhabdomyosarcoma Masquerading as an Inguinal Hernia: A Case Report
Clinical Case Reports, Volume 14, Issue 6, June 2026.ABSTRACT Embryonal paratesticular rhabdomyosarcoma can mimic benign inguinoscrotal conditions such as inguinal hernia. In children with persistent, painless scrotal masses, early cross‐sectional imaging and prompt radical inguinal orchiectomy with histopathological confirmation are essential.
