Long-term Effects of the Anticholinesterases Sarin and Soman on Latencies of Muscle Action Potentials in Mouse Diaphragm Muscle

, 1993
In-vivo administration of the irreversible anticholinesterases sarin and soman has been shown to produce long-term effects on latency and variability of latency of muscle action potentials in in-vitro mouse diaphragm muscle preparations.

Physics‐Constrained Constitutive Learning of Rate‐Limiting Timescales for Efficient Hydrogen‐Based Direct Reduction for Green Steel Making

Advanced Science, EarlyView.
A conversion‐resolved constitutive framework is developed for the hydrogen‐based direct reduction of iron oxide pellets. Effective reaction and transport timescales are inferred directly from measured trajectories and mapped against operating conditions, pellet architecture, and composition. The analysis reveals how late‐stage transport control emerges

Synthesis of 14C Sarin

, 2003
Synthetic routes for the synthesis of [14C] sarin and related nerve agents are described. Triethyl phosphite and [14C] methyl iodide are reacted in the Michaelis-Arbusov reaction to produce diethyl methyl phosphonate which is converted to ...

Interpretable Machine Learning Framework for Nb─Si Based Alloy Design with Enhanced Fracture Toughness

Advanced Science, EarlyView.
An interpretable machine learning framework integrating SHAP and PDP analysis identifies critical design descriptors from 139 physicochemical features for Nb─Si alloys. The framework achieves <7% prediction error and guides the discovery of Nb38.5Ti38.5Si3Zr18V2 alloy with 22.791 MPa·m1/2 fracture toughness, breaking the 20 MPa·m1/2 barrier.

Detection of Sarin with a Fluorinated Polymer-coated Quartz Crystal Microbalance Sensor [PDF]

, 2015
A quartz crystal microbalance (QCM) modified with a thin layer of fluorinated polymer was utilized to  determine sarin. Determination was based on the frequency shifts due to the adsorption and desorption of the compound at the surface of a modified ...

Ultrasound‐Activatable Piezoelectric Hydrogel Reprograms Mitochondrial Epigenetics for Osteoarthritis Therapy via the mTOR/GATD3A Axis

Advanced Science, EarlyView.
An ultrasound‐activatable piezoelectric hydrogel reprograms chondrocyte mitochondrial epigenetics via the mTOR/GATD3A axis, clearing damaged mitochondria and alleviating osteoarthritis progression in both mouse models and human cartilage explants. ABSTRACT The avascular nature of cartilage hinders drug delivery for osteoarthritis (OA) therapy.

Physics‐Informed Neural Network‐Enabled Forward Prediction and Inverse Design of Ring Origami

Advanced Science, EarlyView.
This work presents a KRT‐PINN framework that integrates Kirchhoff rod theory with physics‐informed neural networks for the forward prediction and inverse design of ring origami consisting of closed‐loop rods. The framework predicts stable states of segmented rings with prescribed natural‐curvature profiles and determines the natural‐curvature profiles ...
