A Compact Closed-Form Dynamic Hysteresis Model for Energy-Loss Prediction in Power Magnetic Components

Energies
Magnetic hysteresis strongly influences energy dissipation and efficiency in power magnetic components under time-varying excitation. This work proposes a compact dynamic hysteresis model using a Hammerstein structure, consisting of a closed-form ...

Hysteresis in Unemployment: Evidence from Norwegian Counties [PDF]

The paper tests hysteresis effects in unemployment using aggregate and panel data for Norway. While tests using aggregate or county— specific time series do not reject the null of unit root hysteresis, the panel tests firmly reject the null.

A Thermodynamic Model of Antiferroelectics and Its Application to Electric Field Induced Antiferroelectric‐Ferroelectric Transition in PbZrO3

Advanced Functional Materials, EarlyView.
A thermodynamic model that incorporates ferroelectric, antiferroelectric, and antiferrodistortive orders of PbZrO3${\rm PbZrO}_3$ is established and parameterized based on experimental measurements and first‐principles calculations. We derive a Clapeyron‐like equation for describing the temperature‐dependence of critical electric fields for the ...

Ferroelectric Polarization Enabled Threshold Voltage Modulation in High Electron Mobility Transistor

Advanced Functional Materials, EarlyView.
A comprehensive model is developed to capture the coupled electrostatics of a ferroelectric capacitor and a metal‐insulator‐semiconductor high electron mobility transistor (MISHEMT) connected in ferroelectric‐metal high electron mobility transistor (FeMHEMT) configuration.

Hysteresis vs. natural rate of unemployment: One, the other, or both? [PDF]

This paper re-examines the empirical validity of the hysteresis hypothesis in unemployment rates in terms of education level in 17 OECD countries. To this end for unbalanced panel, we employ Pesaran’s Cross Sectional Dependence (CD) and Cross-Sectionally

Atom Probe Tomography as an Emerging Tool for Understanding Defect‑Driven Mechanisms in HfO2‑Based Ferroelectrics

Advanced Functional Materials, EarlyView.
This Perspective highlights atom probe tomography as a powerful tool for understanding the atomic‐scale defect chemistry in HfO2‐based ferroelectrics. 3D mapping of dopants, point defects, and interface chemistry can provide new insight into defect‐driven mechanisms underpinning the ferroelectricity in the system and guide the design of more reliable ...

Noise‐Limited Bit Precision in Ferroelectric Synaptic Transistors for High‐Resolution Neuromorphic Computing

Advanced Functional Materials, EarlyView.
Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...

n‐Type Semiconductor Hydrogels for Tunable Organic Electrochemical Transistors Operation and Evaporation‐Driven Synergistic Energy Harvesting and Thermal Management

Advanced Functional Materials, EarlyView.
This study develops a tunable n‐OSC hydrogel (PBFDO‐PAAc) platform with a tunable porous network and thermoelectric properties. It demonstrates the first report of n‐OSC hydrogels for evaporation‐driven hydrovoltaic‐thermoelectric electricity generation as well as chemically dedoping‐mediated OECT working mode reconfiguration. This work expands n‐OSCs’
