AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.

Gepta‐EX: a multi‐channel germanium detector for X‐ray absorption fine structure

open access: yesJournal of Synchrotron Radiation, EarlyView.
Gepta‐EX is a compact seven‐channel high‐purity germanium detector designed to deliver high‐resolution fluorescence X‐ray absorption fine‐structure measurements at photon energies where silicon detectors become effectively transparent. It provides excellent energy resolution across a broad energy range, avoids silicon escape‐peak artifacts, and offers ...

SiC resistive X‐ray beam monitor for intensity and position control of synchrotron light

open access: yesJournal of Synchrotron Radiation, EarlyView.
The characterization of a silicon carbide free‐standing membrane resistive detector for spot‐size‐independent X‐ray beam position monitoring in transmission is presented.A silicon carbide (SiC) X‐ray beam position monitor is presented, based on a resistive charge‐division principle derived from lateral‐effect photodiodes and specifically adapted for ...

Europium‐ and dysprosium‐modified strontium aluminate: A luminescent marker system for enhanced gunshot residue detection

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Forensic ballistics is essential in analyzing evidence from firearm use in criminal investigations, with gunshot residue (GSR) detection providing key information about the firearm and shooting conditions. Traditional methods like spectroscopy and scanning electron microscopy (SEM) have limitations in sensitivity, cost, and accessibility ...

Species‐Specific Genetic Patterns in Sympatric Freshwater Turtles Challenge a Generalized Multi‐Species Conservation Approach

open access: yesAnimal Conservation, EarlyView.
We compared genetic diversity and spatial genetic structure in the snapping turtle (Chelydra serpentina; left panel), Blanding's turtle (Emydoidea blandingii; bottom right), and spotted turtle (Clemmys guttata; top right) sampled in areas of co‐occurrence across ~49,160 km2.

Compartmentalisation in cAMP signalling: A phase separation perspective

open access: yesBritish Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.
