The Spinning Manny Indexed Overlay System for VMAT total body irradiation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Purpose While modern intensity‐modulated techniques for total body irradiation (TBI) offer superior organ sparing and improved dose coverage compared to conventional TBI, their complexity has limited widespread adoption. Specifically, when treating individuals with Volumetric Modulated Arc Therapy (VMAT‐TBI), a transition between the head ...

Cell Shuttling in Multifunctional Microsized Needles

Small Structures, Volume 7, Issue 1, January 2026.
We report the bottom‐up synthesis of microsized needles with high volume to area ratio where cells attach preferentially, being explored as a platform for cell delivery. Microsized platforms are crucial for injectable cell delivery systems acting as cell carriers to improve the delivery and retention efficacy at the injury site.

Design Solutions for Reducing the Cogging Torque of PMSM

Advances in Electrical and Computer Engineering, 2013
This paper analyzes design solutions able to reduce the Cogging Torque (CT) amplitude of Permanent Magnet Synchronous Machines (PMSMs). The common point of these solutions is the particular constructions of the stator magnetic core from two concentric steel lamination stacks that leads to a closed stator slots structure in the air-gap region.

Magnetic Field Analysis of Multi‐Segment Modulated Pole Motors Based on the Air Gap Domain Multi‐Harmonic Method

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
A subdomain analytical model for multi‐harmonic air‐gap subdomains is proposed to predict motor magnetic fields containing complex harmonic components. Theoretical analysis demonstrates that this model effectively reduces the matrix dimension during analytical computation, resulting in lower computational time costs for the same harmonic order while ...
