Time‐Resolved Dynamics of Laser Ablation in Liquid with Gas‐Evolving Additives: Toward Molding the Atomic Structure of Nonequilibrium Nanoalloys

Advanced Science, EarlyView.
Laser ablation in liquid still holds great potential for the synthesis of multicomponent non‐equilibrium nanomaterials. Here, time‐resolved experiments reveal that gas‐evolving additives both have chemical effects and reduce shockwave pressure. This approach offers a strategy to control the atomic structure of the nanoalloys, easily switching from ...

Separation of the Aortic and Pulmonary Components of the Second Heart Sound via Alternating Optimization

IEEE Access
An algorithm for blind source separation (BSS) of the second heart sound (S2) into aortic and pulmonary components is proposed. It recovers aortic (A2) and pulmonary (P2) waveforms, as well as their relative delays, by solving an alternating optimization

Model-driven Heart Rate Estimation and Heart Murmur Detection based on Phonocardiogram [PDF]

arXiv
Acoustic signals are crucial for health monitoring, particularly heart sounds which provide essential data like heart rate and detect cardiac anomalies such as murmurs. This study utilizes a publicly available phonocardiogram (PCG) dataset to estimate heart rate using model-driven methods and extends the best-performing model to a multi-task learning ...

Post‐Translational Modifications in Cilia and Ciliopathies

Advanced Science, EarlyView.
This review synthesizes current understanding of post‐translational modifications (PTMs) in ciliary proteins and emphasizes their roles in ciliary formation, homeostasis, and signaling. This review also discusses the implication of PTM dysregulation in ciliopathies and explores therapeutic strategies targeting PTM‐modifying enzymes.
