Integration of multiple perspectives to understand the left ventricular pressure–volume relationship
For more than a century, the pressure–volume loop has offered a simple and elegant way to show how the heart pumps blood. In one picture, it summarizes how the heart fills, contracts, and ejects blood. However, this simplicity has a limitation: the loop treats the heart as if it...

Current Advances in Liver-Targeted Drug Delivery: Synthetic, Biological, and Biomimetic Platforms
Liver-targeted drug delivery offers opportunities to increase therapeutic exposure at sites of hepatic disease while limiting systemic toxicity; however, successful targeting requires more than preferential accumulation of a carrier within the liver. This narrative review critica...

Can UV meet IR in the Swiss cheese?
Abstract We consider the embedding of regular black holes in an expanding universe and study how the ultraviolet modifications to the Schwarzschild geometry that regularize the black hole singularity affect the exterior universe’s expansion rate. We consider several proposals for...

TDNN-Based Ankle Angle Prediction from Lower-Limb Kinematics and Surface EMG
This study presents a Time Delay Neural Network (TDNN) framework for predicting sagittal-plane ankle angle from proximal lower-limb kinematics and surface electromyography (sEMG), with the long-term objective of supporting active ankle prosthesis control. Two TDNN configurations...
