A review of saliency-based sensorless control methods for alternating current machines [PDF]
, 2014 Operation of model-based sensorless control of Alternating Current machines at low and zero speeds is unreliable and can fail. To overcome the limitations of sensorless control at low speeds, several alternative techniques have been developed to ...

Rotation of Crystal Seed During Early Stages of Growth Reveals the Anisotropy of Glass Matrix
Advanced Science, EarlyView.Molecular dynamics simulations reveal that crystal seeds can spontaneously rotate within glass at high temperatures due to anisotropic forces at the glass‐crystal interface. This rotation challenges the long‐held view of glass as an isotropic solid and highlights how atomic‐scale inhomogeneities can influence crystal growth and microstructure of LiNbO3‐

Spintronic Bayesian Hardware Driven by Stochastic Magnetic Domain Wall Dynamics
Advanced Science, EarlyView.Magnetic Probabilistic Computing (MPC) utilizes intrinsic stochastic dynamics in domain walls to establish a hardware foundation for uncertainty‐aware artificial intelligence. Thermally driven domain‐wall fluctuations, voltage‐controlled magnetic anisotropy, and TMR readout enable fully electrical, tunable probabilistic inference.

Advanced Science, EarlyView.ABSTRACT All‐solid‐state batteries (ASSBs) have attracted considerable attention as next‐generation energy storage systems owing to their high energy density and safety. However, their performance is critically limited by insufficient solid–solid interfacial contact and severe chemomechanical degradation, particularly for micro‐sized silicon (µSi ...

The Elephant Trunk Skin Inspires a Highly Sensitive and Deformable, Yet Robust, Armor Skin
Advanced Science, EarlyView.The study presents the elephant trunk‐inspired armor skin with tactile sensing (ETATS). The ETATS architecture stretches and compresses while resisting puncture and tear, and it enables optical detection of pressure and lateral strain. Morphology‐based decoupling of strain and pressure paves the way to sensitive and deformable, yet robust, soft‐robotic
