Mechanics of Telson Ridges in Mantis Shrimp for Impact Analysis and Implications for Bioinspired Elastic Shell Designs

Advanced Functional Materials, EarlyView.
The mantis shrimp telson reveals how ridged biological shields control deformation under impact. Inspired by this architecture, telson‐inspired ridged curved shells transform ridge geometry and macroscopic curvature into bidirectional snap‐through, tunable stiffness, and enhanced hysteretic energy dissipation for multifunctional architected materials ...

Computed Tomography Confirms Increased Left Atrial Volume in Patients with Bayés Syndrome Referred for Catheter Ablation of Atrial Fibrillation

Diagnostics
Background: Bayés syndrome is a recently identified condition that is defined by the presence of an interatrial block on a surface electrocardiogram, in addition to atrial arrhythmias such as atrial fibrillation, tachycardia, or left atrial flutter. This

Comparison of P wave indices between ultramarathon athletes and general population

Physiological Reports
High‐intensity endurance exercise is linked to increased atrial fibrillation (AF) risk. P wave indices are established AF risk markers, but their role in ultramarathon athletes is unexplored.

The Effects of Trimetazidine on P-Wave Duration and Dispersion in Heart Failure Patients

, 2009
Background: P-wave duration and dispersion (PWD) have been shown to be noninvasive predictors for development of atrial fibrillation. Thus, it may be possible to attenuate atrial fibrillation risk through normalization of P-wave duration and dispersion ...

XTRUDE: A Process‐Informed Framework for High‐Fidelity Analysis of Hydrogel Extrusion

Advanced Functional Materials, EarlyView.
Extrusion performance emerges from the interplay between material properties and processing conditions. XTRUDE (eXTrusion Rheology for Understanding and Defining Extrudability) recreates the extrusion environment with in situ pressure and temperature sensing, enabling characteristic pressure signatures to quantify extrusion‐specific phenomena and ...

P-wave Duration and Dispersion in Patients with Peripheral Edema and its Amelioration

Indian Pacing and Electrophysiology Journal, 2007
Background: Attenuation of the P-wave amplitudes in patients with peripheral edema (PERED) has been recently reported, with P-waves regaining some of their amplitude in patients, who subsequently experienced amelioration of their PERED.

P-wave characteristics in Bayés syndrome predict feasibility of anterior mitral line ablation: The Left Anterior Bayés-Derived Mitral Linear Ablation Outcome and Conduction score

Heart Rhythm O2
Background: Bayés syndrome is characterized by a P-wave showing interatrial block (IAB) from impaired Bachmann bundle conduction. In patients without overt IAB, persistent epicardial conduction via the Bachmann bundle can hinder a successful completion ...
