Population genomic diversity and regional structure of lima bean ( Phaseolus lunatus L.) germplasm in Brazil

Josieli Lima da Silva · Ana Flávia Francisconi · João Victor da Silva Rabelo‐Araujo · Caroline Bertocco Garcia · y 12 más

Abstract Lima bean ( Phaseolus lunatus L.) is a crop of substantial social and economic importance, particularly in Brazilian smallholder agriculture. However, key knowledge gaps remain regarding the genomic diversity and population structure of the germplasm cultivated in Brazil. Here, we characterised 46 representati...

A Robust Methodology to Elucidate Kinetics of Room Temperature Electrochemical Propane Adsorption on Platinum

Ashutosh Bhadouria · Durvesh Eknath Parab · Karen Dayana Gonzalez Morales · Chunge Li · y 4 más

Abstract Electrocatalytic activation of alkanes can further decarbonize chemical manufacturing by leveraging affordable renewable electricity and readily available shale gas reserves in the United States. Earlier works have identified the unique role of Pt in adsorbing and activating alkanes, like propane, at room temp...

DIAMETER RATIO EFFECTS ON GRANULAR JAMMING GRIPPER GRASPING FORCE

Jairo Rafael Cortes Lizarazo · Camilo Esteban Miranda Pulido · Fabian Leonardo Velasquez Ladino

Granular jamming grippers are a versatile and adaptable alternative for object manipulation in soft robotics, especially due to their ability to conform to objects with different geometries and generate grasping forces through the variable stiffness of granular media when vacuum pressure is applied (Amend et al., 2012;...

Propiedades psicométricas y validez estructural del Cuestionario de Ansiedad Estado-Rasgo (STAI) en universitarios de Medellín, Colombia

Bibiana A. Castro-Montoya · Carlos E. Arias-Castro · Jorge Emilio Salazar Flórez

Introducción: la ansiedad es una problemática creciente en el ámbito universitario que afecta la salud mental y el rendimiento académico. El objetivo de este estudio fue evaluar las propiedades psicométricas y la validez estructural del Cuestionario de Ansiedad Estado-Rasgo (STAI) en estudiantes universitarios, debido...

Discrepancies in office blood pressure measurement protocols across international guidelines: “Houston, we’ve got a problem.”

Vanildo S. Guimarães-Neto · Annelise M.G. Paiva · Rodrigo Bezerra · Audes D.M. Feitosa · y 9 más

Office blood pressure (OBP) remains a cornerstone of hypertension management. However, contemporary hypertension guidelines recommend different OBP measurement protocols, which vary in procedural details and analytical approaches, and the clinical implications of these differences remain unclear. We compared eight guid...

EFFECT OF BIMODAL GRAIN MIXTURES ON GRANULAR JAMMING GRIPPERS

Jairo Rafael Cortes Lizarazo · Camilo Esteban Miranda Pulido · Fabian Leonardo Velasquez Ladino

Granular jamming grippers have emerged as a promising solution in soft robotics due to their ability to conform to objects with different geometries and subsequently increase their stiffness through vacuum activation. However, their grasping performance depends strongly on the physical characteristics of the granular m...

Challenge-based ex vivo immune profiling reveals stimulus-dependent peripheral immune reprogramming in Alzheimer’s disease

Carlos A Naranjo-Galvis · Jovanny Zabaleta · Ney Alliey-Rodriguez · Luisa Matilde Salamanca-Duque

Abstract Altered immune function is increasingly recognized as a contributor to Alzheimer’s disease (AD); however, it remains unclear whether peripheral immune alterations reflect constitutive inflammation or stimulus-dependent changes in immune responsiveness. Addressing this distinction is critical for understanding...

Source code and simulation framework for Representation Cold Start in Clustered Federated Learning

Alvarado Jaimes, Ricardo

This repository contains the PyTorch implementation of the FedHC-Ward and Fed-SimCLR-Ward frameworks as presented in the article 'Representation Cold Start in Clustered Federated Learning and a Self-Supervised Maturity-Triggered Solution'. It includes scripts for the empirical diagnosis, the signal-to-noise representat...

Supplementary video documenting predation by Imantodes cenchoa on Anolis brasiliensis in central-western Brazil

Diaz-Ricaurte, Juan C. · Navarro Morales, Alejandro · Cavelagna, Rodrigo · Silva Guedes Folly, Henrique · y 1 más

This video documents a predation event by an adult Imantodes cenchoa (blunt-headed tree snake) on an adult Anolis brasiliensis. The interaction was recorded in Parque Estadual das Nascentes do Rio Taquari (18.108806° S, 53.383306° W; 481 m a.s.l.), municipality of Alcinópolis, Mato Grosso do Sul, central-western Brazil...
