Implementation of Principal Component Analysis (PCA)/Singular Value Decomposition (SVD) and Neural Networks in Constructing a Reduced-Order Model for Virtual Sensing of Mechanical Stress.

This study presents the design and validation of a numerical method based on an AI-driven ROM framework for implementing stress virtual sensing. By leveraging Reduced-Order Models (ROMs), the research aims to develop a virtual stress transducer capable of the real-time monitoring of mechanical stresses in mechanical components previously analyzed with high-resolution FEM simulations under a wide range of multiple load scenarios. The ROM is constructed through neural networks trained on Finite Element Method (FEM) outputs from multiple scenarios, resulting in a simplified yet highly accurate model that can be easily implemented digitally.

Validity of a Short Food Frequency Questionnaire for Toddlers of NELA Birth Cohort Study.

Background/objectives: Our aim was to evaluate the reproducibility and validity of a semi-quantitative food frequency questionnaire (FFQ) for the assessment of usual nutrient and food intakes in children of 18 months old.

Methods: We included 103 toddlers aged 18 months from the Nutrition in Early Life and Asthma (NELA) birth cohort study. A 47-item FFQ was administered twice to parents with a 3-month interval.

Clinical and In Vitro Safety of AO 1167B: A Double-Blind, Placebo-Controlled Trial.

(1) Background: , a lactic acid-producing bacterium, displays characteristics of both and genera. Clinical evidence suggests its potential health benefits. This study evaluated the safety of AO1167B as a candidate probiotic supplement.

Macromolecular interaction mechanism of the bacteriocin EntDD14 with the receptor binding domain (RBD) for the inhibition of SARS-CoV-2 and the JN.1 variant: Biomedical study based on elastic networks, stochastic Markov models, and macromolecular volumetric analysis.

Bacteriocins, a class of molecules produced by bacteria, exhibit potent antimicrobial properties, including antiviral activities. The urgent need for treatments against SARS-CoV-2 has proposed bacteriocins such as enterocin DD14 (EntDD14) as potential therapeutic agents. However, the mechanism of macromolecular interaction of EntDD14 for the inhibition of SARS-CoV-2 is not yet fully understood, and its efficacy against variants like JN.

The impact of hypoalbuminemia on the long-term prognosis of patients with acute heart failure: The modifying role of carbohydrate antigen 125.

Aims: Hypoalbuminemia is frequently found in patients with heart failure (HF), associated with higher morbimortality in acute HF (AHF). Moreover, Carbohydrate Antigen 125 (CA125) is elevated in most of the AHF patients. In this cohort of patients admitted for AHF, our objective was to evaluate the association between hypoalbuminemia and long-term outcomes, including mortality and HF readmissions, stratified by CA125 concentration.
