A low-noise instrumentation amplifier with built-in anti-aliasing for hall sensors

, 2021
We present a compact, versatile Hall readout system with digital output, fully integrated in 180 nm technology. The core of the system is an instrumentation amplifier architecture that provides inherent anti-aliasing filtering, where the anti-aliasing ...

Angular‐Adaptive Reconfigurable Spin‐Locked Metasurface Retroreflector

Advanced Science, Volume 8, Issue 21, November 3, 2021., 2021
An angular‐adaptive spin‐locked retroreflector is realized using a reconfigurable metasurface composed of mechanically rotational meta‐atoms. The reflection phase of meta‐atoms can be controlled dynamically by altering the orientation states based on the Pancharatnam‐Berry phase.

Thermoregulation is not impaired in breast cancer survivors during moderate‐intensity exercise performed in warm and hot environments

Physiological Reports, Volume 9, Issue 14, July 2021., 2021
Thermoregulation was not disadvantaged in BCS compared to controls during moderate‐intensity exercise under heat stress. However, self‐paced exercise performance was reduced for BCS regardless of environmental temperature. Abstract This study aimed to assess how female breast cancer survivors (BCS) respond physiologically, hematologically, and ...

A Low Noise Multipath Chopper-Stabilized Operational Amplifier Using Dynamic Element Matching Gain-Boosting and Low Input Current Adaptive Clock-Boosting Chopper Switch

IEEE Access
This paper presents a low noise multipath operational amplifier with chopper-stabilized and gain-boosted low-frequency path (LFP) amplifier. The LFP amplifier adopts the gain-boosting using dynamic element matching (DEM) and buffered adaptive clock ...

Infrared‐Microwave Compatible Stealth Transparent Metasurface With Digital Camouflage and Hybrid Absorption‐Scattering

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Traditional metasurfaces suffer from the drawbacks of pure microwave absorption and low IR emissivity stealth, namely failing to match complex ambient backgrounds with varying IR emissivity and generating excess heat accumulation (enhanced IR thermal radiation).

Prognostic Implications of Sleep Architecture for Patients Admitted to the Intensive Care Unit With Status Epilepticus

Annals of Clinical and Translational Neurology, Volume 13, Issue 6, Page 1179-1185, June 2026.
ABSTRACT Objective Status epilepticus (SE) is associated with significant mortality. Sleep architecture may reflect normal brain function. Impaired sleep architecture is associated with poorer outcomes in numerous conditions. Here we investigate the association of sleep architecture in continuous EEG (cEEG) with survival in SE.

Copper Contact for Perovskite Solar Cells: Properties, Interfaces, and Scalable Integration

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
Copper electrodes, as low‐cost, scalable contacts for perovskite solar cells, offer several advantages over precious metals such as Au and Ag, including performance, cost, deposition methods, and interfacial engineering. Copper (Cu) electrodes are increasingly considered practical, sustainable alternatives to noble‐metal contacts in perovskite solar ...
