An integrated platform for 2‐D and 3‐D optical and electrical mapping of arrhythmias in Langendorff‐perfused rabbit hearts

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Integrated multimodal platform for panoramic cardiac mapping in isolated heart experiments. On the left, an image of the experimental setup during data acquisition showing a Langendorff‐perfused rabbit heart surrounded by three optical cameras (CAM A, B and C) positioned 120° apart, each coupled with high‐power LEDs for panoramic

A Longitudinal Study of Children's Hippocampal Development: Investigating Maternal Physical Activity, Depression, and Education

open access: yesDevelopmental Neurobiology, Volume 86, Issue 2, April 2026.
ABSTRACT The developing hippocampus is particularly sensitive to early environmental influences, including during pregnancy. This longitudinal neuroimaging study examined associations between prenatal maternal physical activity and depression, maternal education, and hippocampal development from early childhood to early adolescence.

Suavizamiento de los vértices de un polígono por medio de un spline cónico

open access: yesRevista Integración, 1997
We prove that every irreducible conic can be parametrically represented by two rational quadratic functions. An algorithm for smoothing the vertices of a poligonal by a conic spline with continuous tangent is proposed.

Integration of Machine Learning With PBPK and QSAR Modeling Approaches to Facilitate Drug Discovery and Development

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 4, April 2026.
ABSTRACT This review examines the application of machine learning (ML) in physiologically based pharmacokinetic (PBPK) modeling through improved prediction of input parameters, particularly via quantitative structure–activity relationship (QSAR) models, for absorption, distribution, metabolism, and excretion (ADME) properties across drug development ...

Automatic Generation of T-Splines with Extraordinary Points Based on Domain Decomposition of Quadrilateral Patches

open access: yesMathematics
Isogeometric analysis (IGA) is a numerical methodology for solving differential equations by employing basis functions that preserve the exact geometry of the domain. This approach is based on a class of mathematical functions known as NURBS (Non-Uniform

Stability Thresholds of Atomically Dispersed Platinum Catalysts for Solar Hydrogen Production

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 10, 2 March 2026.
This work identifies a critical dispersion threshold for Pt single‐atom photocatalysts. Below this limit, isolated Pt sites remain stable under illumination and deliver up to 82‐fold higher hydrogen evolution reaction (HER) activity than Pt nanoparticles.
