An Active Knee–Ankle–Foot Orthosis With Torque‐Dense, Low‐Impedance Knee Actuation

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents the simulation, design, and clinical validation of a robotic active KAFO with torque‐sensitive actuation. By passively and continuously adapting the transmission ratio in response to the knee torque, the torque‐sensitive actuator overcomes the tradeoff between torque, weight, and impedance observed in conventional robot actuators,

On the Impact of Mechanical Constraint on Band Structure and Photo‐Elastic Effect in Photonic Resonators

open access: yesAdvanced Physics Research, EarlyView.
We computationally investigate the mechanical, electronic, and optical properties of strained GeSn microdisks on silicon substrates. By combining photo‐elasticity, strain‐dependent band‐structure calculations, and optical mode analysis, we study how strain distribution, structural configuration, and temperature affect the electronic band structure and ...

Motor Physiology Transcranial Magnetic Stimulation–Based Biomarkers and Associated Neurocognitive Profiles in Attention‐Deficit/Hyperactivity Disorder

open access: yesAnnals of the Child Neurology Society, EarlyView.
ABSTRACT Purpose Attention‐deficit/hyperactivity disorder (ADHD) is a highly prevalent and heterogeneous neurodevelopmental condition for which current diagnostic approaches rely on symptom‐based classifications that do not capture underlying neurobiology.

Sudden unexpected death in epilepsy: An Italian expert consensus statement on risk, mechanisms, prevention, and therapeutic strategies

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Sudden unexpected death in epilepsy (SUDEP) is a leading cause of premature mortality in people with epilepsy, particularly in those with tonic–clonic seizures (TCSs), developmental and epileptic encephalopathies (DEEs), and drug‐resistant epilepsy.

Study on Fluid Pressure in Tubing, Dynamic Stress in Reservoir, and Fracture Propagation Morphology During Variable‐Rate Hydraulic Fracturing

open access: yesEnergy Science &Engineering, EarlyView.
Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

RSM–ANFIS‐Based Process Optimization of Thermo‐Sonication of Amla Juice: Effect on Enzyme Inactivation, Physico‐Chemical, Phytochemical, Sensory, and Microbiological Quality

open access: yesFood Chemistry International, EarlyView.
Thermo‐sonication parameters were optimized to maximize PPO inactivation while maintaining overall juice quality. ANFIS demonstrated superior predictive accuracy with higher R2 and lower RMSE compared to RSM. Further, the quality assessment of treated juice highlighted the potential of thermo‐sonication as a sustainable alternative to conventional ...
