A 40.68‐MHz Active Rectifier Using PLL and PWM Control of DC‐DC Converter for ON/OFF Delay Compensation

International Journal of Circuit Theory and Applications, EarlyView.
A ramp‐based phase‐locked loop (RPLL) active rectifier operating at 40.68 MHz compensates switching delay variations to improve phase alignment. The proposed architecture achieves 90.3% peak power conversion efficiency and 98.0% voltage conversion ratio for high‐frequency wireless power transfer in implantable medical devices.

An Ultra‐Low‐Power Biopotential Acquisition Analog Front‐End Chip for Wearable Devices

International Journal of Circuit Theory and Applications, EarlyView.
A 0.8‐V, 1.2‐μW biopotential AFE combines a chopper‐stabilized CCIA with dual‐time‐scale EDO management. The slow DSL preserves > 1 GΩ input impedance, whereas an event‐triggered fast‐recovery path shortens return to the linear range after abrupt electrode‐offset disturbances. ABSTRACT A 0.8‐V, 1.2‐μW biopotential analog front‐end (AFE) IC is presented

Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

Deep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

Reward Processing in Binge Eating and Harmful Drinking: A Systematic Review

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Binge eating and harmful drinking commonly co‐occur, which worsens the physical and psychological consequences associated with either behavior alone. Reward processing alterations have been demonstrated among individuals who engage in binge eating or harmful drinking alone; however, there is limited understanding of how different ...

Inhibitory Control Tells Only Part of the Story: Reward Sensitivity Moderates the Prospective Link Between the No‐Go P3 and Emerging Eating Pathology in Early Adolescents

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Early adolescence is characterized by the onset of mental health problems, including eating pathology (e.g., body image concerns, restrictive eating). Inhibitory control (IC) and reward sensitivity (RS) are two key traits that have been implicated in the development of eating problems.

Confined Hot Carrier Cooling Via Excited‐State Energy Gap Engineering in Graphyne Carbon Allotropes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The excited‐state energy gap (EEG), regulated by the concentration of sp‐hybridized carbon, provides an effective handle for tuning electron–phonon coupling behavior. This design enables long‐lived confinement of hot carriers near the top of the EEG with controllable energy levels.
