Left bundle branch area vs biventricular pacing for cardiac resynchronization therapy: the LEFT-BUNDLE-CRT trial

Óscar Cano · Víctor Pérez-Roselló · Andrea Di Marco · Javier Ramos-Maqueda · y 8 más

Abstract Background and Aims Conduction system pacing has emerged as an alternative to biventricular pacing (BiVP) for cardiac resynchronization therapy (CRT). The left-bundle CRT trial evaluated whether left-bundle branch area pacing (LBBAP) is non-inferior to BiVP in patients eligible for CRT. Methods The left-bundle...

Structural Extension of the Radial Acceleration Relation: Evidence for a Two-Dimensional Dynamical Law in Galaxies

Desalvador Ontibon, Mauricio

We present an empirical extension of the Radial Acceleration Relation (RAR) by introducing a local structural parameter, Θ = d log g_bar / d log r, which encodes the radial variation of the baryonic gravitational field. Using a sample of 8580 data points from 143 galaxies, we show that Θ acts as an independent observab...

Transición Demográfica en Santander y su Impacto en el Sistema Educativo

Pérez Pulido, Miguel Oswaldo

Colombia atraviesa la transición demográfica más pronunciada de su historia reciente. En 2025, el país registró apenas 433.678 nacidos vivos, el valor más bajo de la última década, lo que representa una caída acumulada superior al 20% respecto a 2014. El departamento de Santander, con 294.964 nacimientos acumulados ent...

Combination and interpretation of differential Higgs boson production cross sections in proton-proton collisions at $$ \sqrt{s}=13 $$ TeV

Chekhovsky, Vladimir · Hayrapetyan, Aram · Makarenko, Vladimir · Tumasyan, Armen · y 196 más

A bstract Precision measurements of Higgs boson differential production cross sections are a key tool to probe the properties of the Higgs boson and test the standard model. New physics can affect both Higgs boson production and decay, leading to deviations from the distributions that are expected in the standard model...

Micromechanical modeling of the hierarchical elytral architecture of the diabolical ironclad beetle for predicting its exceptional compressive behavior

ROMERO SUAREZ, GERMAN ORLANDO · VILLEGAS, DIEGO · Pinto Hernández, William

This work presents a micromechanical modeling framework for predicting the compressive response of the hierarchical elytral architecture of the diabolical ironclad beetle (Phloeodes diabolicus). The proposed approach integrates inclusion-based theories (Eshelby, Mori–Tanaka, and differential schemes) with multiscale st...
