Optimizing the Jiles-Atherton Model of Hysteresis by a genetic algorithm
, 2001 Modeling magnetic components for simulation in electric circuits requires an accurate model of the hysteresis loop of the core material used. It is important that the parameters extracted for the hysteresis model be optimized across the range of ...

History-Dependent Stress Relaxation of Liquids under High-Confinement: A Molecular Dynamics Study
Lubricants, 2022 When liquids are confined into a nanometer-scale slit, the induced layering-like film structure allows the liquid to sustain non-isotropic stresses and thus be load-bearing.

Architecture‐Driven Sensor Stability in Weft‐Knitted Engineering Textiles
Advanced Engineering Materials, EarlyView.Textile‐integrated sensor architectures are systematically compared to evaluate their electromechanical behavior under combined mechanical and environmental loading. Pocket‐based integration exhibits stable and reproducible signals, whereas tunnel‐based routing shows higher sensitivity accompanied by increased variability.

Handling Hysteresis in a Referral Marketing Campaign with Self-Information. Hints from Epidemics
Mathematics, 2021 In this study we show that concept of backward bifurcation, borrowed from epidemics, can be fruitfully exploited to shed light on the mechanism underlying the occurrence of hysteresis in marketing and for the strategic planning of adequate tools for its ...

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring
Advanced Engineering Materials, EarlyView.Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

Spontaneous unidirectional rotation of a symmetric gear driven by spherical active particles
National Science OpenTime reversal asymmetry and spatial anisotropy are considered two prerequisites for Brownian ratchet. An intriguing realization can be achieved by placing an asymmetric gear in the suspension of motile rod-like bacteria.
