Physiologically Constrained Musculoskeletal Neural Network for Multi-DoF Joint Kinematics Estimation from Partially Observed sEMG

arXiv:2606.07476v1 Announce Type: new Abstract: This paper investigates multi-degrees of freedom (DoF) joint kinematics estimation under partially observed surface electromyography (sEMG), where only a subset of task-relevant muscles can be measured due to anatomical inaccessibility or sensor constraints. A novel musculoskeletal neural network (MSK-NN) is proposed to estimate multi-DoF joint angles while simultaneously inferring activations for both measured and unmeasured muscles. MSK-NN...

Physics-Embedded Neural Networks for sEMG-based Continuous Motion Estimation

arXiv:2506.22459v1 Announce Type: cross Abstract: Accurately decoding human motion intentions from surface electromyography (sEMG) is essential for myoelectric control and has wide applications in rehabilitation robotics and assistive technologies. However, existing sEMG-based motion estimation methods often rely on subject-specific musculoskeletal (MSK) models that are difficult to calibrate, or purely data-driven models that lack physiological consistency. This paper introduces a novel...

Scientists uncover RNA's hidden role as protein chaperone

Scientists uncover RNA's hidden role as protein chaperone Gaby Clark Scientific Editor Andrew Zinin Lead Editor Proteins are how cells get work done. They carry out nearly every important cellular task, from ferrying messages to controlling which genes are turned on or off. And in order for proteins to perform their various roles, the strings of amino acids that make them up need to be folded into the correct shape.

OncoReason: Structuring Clinical Reasoning in LLMs for Robust and Interpretable Survival Prediction

Announce Type: replace Abstract: Predicting cancer treatment outcomes requires models that are both accurate and interpretable, particularly in the presence of heterogeneous clinical data. While large language models (LLMs) have shown strong performance in biomedical NLP, they often lack structured reasoning capabilities critical for high-stakes decision support. We present a unified, multi-task learning framework that aligns autoregressive LLMs with clinical reasoning for outcome prediction...

'People think I love to hit every ball, but ...': Sooryavanshi's answer to Ashwin

Young batting sensation Vaibhav Sooryavanshi was at his destructive best throughout IPL 2026, dispatching some of the world's leading bowlers into the stands with ease. Known for his fearless approach and explosive strokeplay, the teenager consistently kept the scoreboard moving at a breathtaking pace while leaving bowlers struggling to contain him. Sooryavanshi was named the Most Valuable Player of the tournament after finishing as the leading run-scorer with 776 runs from 16 innings at an...

SHERLOC: An interpretable deep learning model for longitudinal circulating tumor DNA data in survival analysis

Longitudinal circulating tumor DNA (ctDNA) measurements offer a noninvasive means to monitor treatment response, but clinical trial data present substantial methodological challenges due to high-dimensional short longitudinal ctDNA sequences and limited sample sizes. We introduce SHERLOC, a deep learning framework specifically designed for survival analysis using longitudinal on-treatment ctDNA data, which integrates shared temporal representations of gene-level variant allele frequencies,...
