A Modular AC-DC Power Converter with Zero Voltage Transition for Electric Vehicles
Energies, 2017 A study of the fundamental of operation of a three-phase AC-DC power converter that uses Zero-Voltage Transition (ZVT) together with Space Vector Pulse Width Modulation (SVPWM) is presented. The converter is basically an active rectifier divided into two

Resilient Biophysical Phenotype of Memory CD4 + T Cells in Long‐Lived Mice
Immunology, Volume 178, Issue 2, Page 363-374, June 2026.Aging is associated with increased stiffness and reduced migratory capacity of memory CD4+ T cells; however, these biophysical declines do not persist in exceptionally long‐lived mice. Instead, long‐lived individuals preserve T cell mechanics, migration and intracellular architecture, supporting mechanical resilience as a hallmark of successful immune ...

Engineering Reports, Volume 8, Issue 4, April 2026.Welding power and post‐weld heat treatment (PWHT) at 850°C influence phase transformations in S32205 duplex stainless steel, promoting sigma phase formation and reducing corrosion resistance. PWHT at 850°C also replicates HAZ‐like microstructures in base metal, enabling improved characterization of weld joint properties.

Design and Validation of a Passive Solar Tracking Sensor Based on Gnomon Shadow Analysis
International Journal of Photoenergy, Volume 2026, Issue 1, 2026.Solar tracking is essential for efficiency, yet current market solutions present a trade‐off: Active systems are precise but expensive and computationally demanding, while low‐cost passive systems (e.g., LDRs) often lack accuracy. To address this gap, this work presents the design and validation of a passive solar tracking sensor based on gnomon shadow
