DefectAtlas-20: A Real-World Image Dataset for Joint Material and Surface-Condition Classification

Buettner, Ricardo · Fischer-Brandies, Leopold · Pasold, Lukas · Eisentraut, Luca

DefectAtlas-20 is a real-world image dataset for joint material and surface-condition classification. It contains 13,233 RGB images organized into 20 mutually exclusive classes, formed by combining ten commonly encountered material categories with defect and non-defect surface conditions. The dataset comprises 7,060 de...

A Double-Hit Model of Early-Life Stress and High-Fat Feeding Reveals Enhanced Exocrine Pancreatic Remodeling

Laura García-Orozco · Carlos Alberto Mandarim-de-Lacerda · Bélgica Vásquez

Adverse childhood experiences are associated with long-term metabolic disturbances, yet their effects on the exocrine pancreas remain poorly understood. Using maternal separation (MS) as a model of early-life stress, this study examined whether MS modifies the exocrine pancreatic response to a post-weaning high-fat die...

Power Converter-Based Impedance Spectroscopy for Supercapacitors: Theory, Simulation and Experimental Verification

Diego Alejandro Herrera-Jaramillo · Juan David Bastidas-Rodríguez · Carlos Andrés Ramos-Paja

This paper addresses the need for cost-effective and integrated impedance spectroscopy (IS) techniques for supercapacitors (SCs), particularly in applications where conventional frequency response analyzers (FRAs) are impractical due to their high cost and lack of portability. A power converter-based methodology is pro...

GWTC-4.0: Constraints on the Cosmic Expansion Rate and Modified Gravitational-wave Propagation

The LIGO Scientific Collaboration · the Virgo Collaboration · the KAGRA Collaboration · Abac, A. G. · y 196 más

Abstract We analyze data from 142 of the 218 gravitational-wave (GW) sources in the fourth LIGO–Virgo–KAGRA Collaboration (LVK) Gravitational-Wave Transient Catalog (GWTC-4.0) to estimate the Hubble constant H 0 jointly with the population properties of merging compact binaries. We measure the luminosity distance and r...

Proximal femoral replacement for non-oncologic reconstruction: functional outcomes and survivorship in 30 patients

Edgar Manuel Bodu Lamberti · Gary Monclou · Camila Karduss Preciado

Background: Proximal femoral replacement (PFR) is a useful salvage option for reconstruction after massive proximal femoral bone loss. However, functional outcomes in non-oncologic cases remain underreported. The purpose of this study was to evaluate postoperative function, complications, and implant survival after PFR...

Weather Shocks and Banking Credit Risk: Evidence for Small Rural Municipalities in Colombia

Julián Benavides Franco · Jaime Andrés Carabali · Luis Ángel Meneses Cerón · Alex Pérez · y 1 más

This paper studies the impact of weather shocks on the credit risk of bank portfolios in small and rural municipalities in Colombia, which are highly vulnerable to these climate variations. It addresses the relationship between extreme temperature and precipitation events and the increase in the proportion of loans at...

Genome evolution and long-term demographic history in true crocodiles

Ana M Saldarriaga-Gómez · Agusto Luzuriaga-Neira · Mario Vargas-Ramírez · George Amato · y 1 más

Abstract Reference-quality genomes remain scarce for true crocodiles (Crocodylus), limiting comparative analyses of genome evolution and demographic history. Here, we generated and analyzed 2 long-read genomes, 1 for Crocodylus intermedius and 1 for C. niloticus, to investigate genome architecture, coalescent effective...

Effects of Prior Thermal Exposure of a Soil–Compost System on Potentially Bioavailable Mercury and Its Accumulation in Rice Grown on Mining-Impacted Soils

Marisol Laza-Durante · Iván David Urango-Cárdenas · Germán Enamorado-Montes · Elvia Valeria Durante-Yánez · y 2 más

Mercury (Hg) mobility in contaminated soils may be altered by solarization-induced thermal disturbance and organic amendments. This study evaluated whether a cover-induced prior solarization pretreatment of a mining-impacted soil–compost system modifies the operationally defined labile Hg fraction (F1 + F2, considered...
