A model of β‐adrenergic stimulation in human ventricular cells for tissue‐scale simulations of sympathetically modulated tachycardias

The Journal of Physiology, EarlyView.
Abstract figure legend Modelling β‐adrenergic stimulation in sympathetically remodelled ventricular substrates. Myocardial infarction could result in sympathetic remodelling in ventricular tissues, which affects arrhythmia dynamics. However sympathetic remodelling is challenging to control experimentally; therefore we created an ionic model that ...

Influence of Acrylonitrile Content on Processing, Morphology, Thermal Behavior, and Mechanical Properties of PA/NBR Thermoplastic Vulcanizates

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Influence of acrylonitrile (ACN) content on the processing behavior and morphological development of PA/NBR thermoplastic vulcanizates. Torque‐time profiles, SEM, and SEM/AFM images show that an intermediate ACN level (38%) promotes improved phase dispersion and morphological uniformity, especially with increased processing time, resulting in the most ...

Model Predictive Path‐Following Control for a Quadrotor

PAMM, Volume 26, Issue 1, March 2026.
ABSTRACT Automating drone‐assisted processes is a complex task. Many solutions rely on trajectory generation and tracking, whereas in contrast, path‐following control is a particularly promising approach, offering an intuitive and natural approach to automate tasks for drones and other vehicles.

Segmented Gurney Flaps for Improved Wind Turbine Wake Recovery

Wind Energy, Volume 29, Issue 3, March 2026.
ABSTRACT When wind passes through the rotor of a wind turbine, the velocity is decreased while turbulence is increased. The region of decreased wind speed behind the rotor is known as the wind turbine wake and is bounded by a complex structure of helical vortices. This structure occurs to be more stable in low ambient turbulence and low tip speed ratio

Preclinical Evaluation of the Effect of Liquid Platelet–Rich Fibrin and a Volume‐Stable Collagen Matrix on Periodontal Regeneration

Journal of Clinical Periodontology, Volume 53, Issue 3, Page 424-435, March 2026.
ABSTRACT Aim To evaluate the regenerative potential of liquid platelet–rich fibrin (PRF), with and without a volume‐stable collagen matrix (VCMX), in periodontal intrabony defects using histological, histometric and micro‐CT analyses. Materials and Methods One‐wall intrabony defects were surgically created in six beagle dogs and treated with either ...

Auditory Hair Cell Mechanotransduction Channels Dynamically Shape the Mechanical Properties of Their Membrane Environment

Advanced Science, Volume 13, Issue 7, 3 February 2026.
This work shows, for the first time, that the stereocilia membrane in cochlear hair cells is dynamically regulated by the mechanotransduction channel to impact the membrane mechanical properties. This work provides direct evidence that the opening and closing associated with the MET channel is regulating the membrane viscosity suggesting that the MET ...
