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

Reweighting Scheme for the Calculation of Grand‐Canonical Expectation Values in Quantum Monte Carlo Simulations With a Fermion Sign Problem

Contributions to Plasma Physics, EarlyView.
ABSTRACT Ab initio path integral Monte Carlo (PIMC) simulations constitute the gold standard for the estimation of a broad range of equilibrium properties of a host of interacting quantum many‐body systems spanning a broad range of conditions from ultracold atoms to warm dense quantum plasmas.

Implementation of the E×B and Grad‐B Drift in the EMC3 Code and Verification Using the Method of Manufactured Solutions

Contributions to Plasma Physics, EarlyView.
ABSTRACT Effective management of particle and power exhaust is essential for fusion reactor operation, requiring accurate 3D modeling of divertor physics. The EMC3 code is a well‐established Monte Carlo tool for plasma transport in stellarator edge regions, but until now lacked E×B$$ E\times B $$ and diamagnetic drifts.

Localized 3D acoustic streaming in microdroplets using high‐frequency micro‐beam IDTs

Droplet, EarlyView.
Miniaturized 160 MHz acoustic microbeam transducers, with a size much smaller than droplets, enable precise localized actuation, generating complex three‐dimensional streaming and tunable particle aggregation. This concept provides high‐resolution, non‐contact fluid manipulation for biosensing, lab‐on‐chip diagnostics, and targeted drug screening ...

Micro‐QuEChERS Extraction for Broad‐Spectrum LC‐QQQ‐MS Quantification of Nitazene Analogs in Plasma: A Validated Method With Casework Application

Drug Testing and Analysis, EarlyView.
Micro‐QuEChERS sample preparation coupled to LC‐QQQ‐MS enabled sensitive quantification of nitazene analogs in 100 μL of plasma. The validated method provided low detection limits and was successfully applied to an authentic intoxication case involving N‐pyrrolidino protonitazene, supporting clinical and forensic toxicology workflows.
