CNC Toolpath-Driven Thermal Modeling of WAAM with Direct Correlation to Microstructural Evolution

Theylor Andres Amaya Villabon · Andres Fernando Gil Plazas · Julián David Rubiano Buitrago · Stefan Böhm · y 1 más

Abstract Wire Arc Additive Manufacturing (WAAM) involves highly transient thermal cycles, repeated reheating, and strong spatial temperature gradients, all of which govern the final microstructure of the deposited material. In this work, a three-dimensional transient thermal model for WAAM of ER70S-6 carbon steel was d...

First Case of Congenital Toxoplasmosis After Maternal Reinfection in Colombia: Serotyping Evidence of Reinfection by Different Strains

Sandra Beltrán-Higuera · Lucia Moncada-Roa · Elizabeth Torres-Morales · Jorge Enrique Gómez-Marín

Herein, we report the first case of confirmed maternal reinfection in an immunocompetent woman, resulting in congenital toxoplasmosis in Colombia. The child was referred to an infectious disease pediatrician at 17 months of age because of strabismus and typical bilateral chorioretinitis scars with elevated immunoglobul...

S. Abbaslu · A. Abed Abud · R. Acciarri · L. P. Accorsi · y 195 más

We present the measurement of π + -argon inelastic cross sections using the ProtoDUNE single-phase liquid argon time projection chamber in the incident π + kinetic energy range of 500–800 MeV in multiple exclusive channels (absorption, charge exchange, and the remaining inelastic interactions). The results of this anal...

Resistance to novel β-lactam/β-lactamase inhibitors among carbapenem-resistant Pseudomonas aeruginosa and clinical implications in the prospective observational Pseudomonas study

Lee S. Gottesdiener · Yixuan Li · Kerryl E. Greenwood-Quaintance · Lauren Komarow · y 27 más

ABSTRACT Novel β-lactam/β-lactamase inhibitors (βL/βLIs) are important therapies for carbapenem-resistant Pseudomonas aeruginosa (CRPA). However, the global extent of resistance to these agents and the impact of resistance on patient outcomes are unclear. We therefore evaluated patients with CRPA isolates at 35 hospita...

Cannabinoid receptor expression profiling in lymphocyte subsets reveals clinically relevant immune patterns in SLE

Angie M. Rosero · Lady J. Rios-Serna · Carlos A. Cañas

Introduction This study aimed to determine the expression of cannabinoid receptors in lymphocytes from patients with systemic lupus erythematosus (SLE) compared with healthy controls, and to evaluate whether receptor expression is associated with disease activity. Methods Using peripheral blood mononuclear cells from 3...

Geography and diet determine the cecal microbiota of Cavia porcellus and reveal a fermentative core within its intestinal ecosystem

Darío Alejandro Romero-Benavides · Adriana Elisabeth Orbes-Villacorte · Leyla Ríos Álvarez · Alejandro Caro-Quintero

Abstract Background Cavia porcellus is a small herbivorous mammal extensively raised as a protein source in South America, with a population exceeding 100 million. Its high metabolic demands are met through cecal microbial fermentation, yet the intestinal microbiota supporting this process remains poorly characterized....
