Reconstructing attractors with autoencoders.

Chaos

January 2025

IMAS-CONICET and Departamento de Matemática, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, Ciudad Universitaria, 1428 Buenos Aires, Argentina.

We propose a method based on autoencoders to reconstruct attractors from recorded footage, preserving the topology of the underlying phase space. We provide theoretical support and test the method with (i) footage of the temperature and stream function fields involved in the Lorenz atmospheric convection problem and (ii) a time series obtained by integrating the Rössler equations.

Coronary revascularisation deferral based on quantitative flow ratio or fractional flow reserve: a post hoc analysis of the FAVOR III Europe trial.

EuroIntervention

January 2025

Hospital Clínico San Carlos IDISSC, Complutense University of Madrid, Madrid, Spain and Centro de Investigación Biomédica en Red - Enfermedades Cardiovasculares (CIBERCV), Instituto de Salud Carlos III, Madrid, Spain.

Background: Safe deferral of revascularisation is a key aspect of physiology-guided percutaneous coronary intervention (PCI). While recent evidence gathered in the FAVOR III Europe trial showed that quantitative flow ratio (QFR) guidance did not meet non-inferiority to fractional flow reserve (FFR) guidance, it remains unknown if QFR might have a specific value in revascularisation deferral.

Aims: We aimed to evaluate the safety of coronary revascularisation deferral based on QFR as compared with FFR.

Background: The global burden of metabolic diseases is increasing, but estimates of their impact on primary liver cancer are uncertain. We aimed to assess the global burden of primary liver cancer attributable to metabolic risk factors, including high body mass index (BMI) and high fasting plasma glucose (FPG) levels, between 1990 and 2021.

Methods: The total number and age-standardized rates of deaths and disability-adjusted life years (DALYs) from primary liver cancer attributable to each metabolic risk factor were extracted from the Global Burden of Disease Study 1990-2021.

Metal chalcogenides have been extensively studied for thermoelectric applications. Among other metal chalcogenides, silver selenide (AgSe) is considered one of the most promising n-type semiconducting materials for thermoelectric applications due to its low band gap value, Seebeck coefficient, and superior power factor (PF) rendered at room temperature. However, one of the main drawbacks of using AgSe as a thermoelectric material on a large scale is the time-consuming physical methods to obtain them, and the need for high vacuum synthesis conditions as well as high-cost.

Acute hepatitis of unknown etiology (non-HepA-E hepatitis) emerged affecting children in 2021 and in parallel with the COVID-19 pandemic. In the present article, we performed an analysis between two plasma samples from pediatric patients, one with non-HepA-E hepatitis and the other healthy, to evaluate possible proteomic alterations associated with viral targets as possible causative agents and pathophysiological processes using the high-resolution and label-free LC-MS/MS technique. We identified 72 altered differentially expressed proteins, 45 upregulated and 27 downregulated.
