Power Converter-Induced Current Harmonics- Based Mechanical Stress Estimation in a PMSG Wind Turbine
IEEE AccessVariable-speed type 4 wind turbines are largely based on Permanent Magnet Synchronous Generator architectures coupled with power converters. Although these systems operate over a wide speed range, they introduce current harmonics at the generator output,

Vectorial formalism for analysis and design of polyphase synchronous machines [PDF]
, 2003 A vectorial formalism for analysis and design of polyphase synchronous machines without reluctance and saturation effects is described. We prove the equivalence of such a machine with a set of magnetically independent machines, which are electrically and

Evolution of Physical Intelligence Across Scales
Advanced Intelligent Discovery, EarlyView.By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy
BMEMat, EarlyView.Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...
