Artificial Intelligence to Determine Correct Midsagittal Plane in Dynamic Transperineal Ultrasound

open access: yesJournal of Clinical Ultrasound, EarlyView.
We have created a model that allows determining the correct midsagittal plane captured by transperineal dynamic ultrasound, with a level of agreement with the expert examiner similar to or higher than that of a junior or senior examiner. ABSTRACT Purpose To create and validate a machine learning(ML) model that allows for identifying the correct capture

The Impairment of Body Condition Transiently Increases Oxidative Stress: A Dietary Restriction Experiment in Partridges

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT A proper body condition determines the correct functioning of physiological processes and the optimal expression of fitness‐related traits. Among these processes, maintaining the redox balance is essential to protect the organism from damage caused by oxidative stress.

On Endomorphism Universality of Sparse Graph Classes

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT We show that every commutative idempotent monoid (a.k.a. lattice) is the endomorphism monoid of a subcubic graph. This solves a problem of Babai and Pultr and the degree bound is best‐possible. On the other hand, we show that no class excluding a minor can have all commutative idempotent monoids among its endomorphism monoids. As a by‐product,

Stratigraphy and geomorphology of Des‐Cubierta Cave (Pinilla del Valle, Madrid, Spain): Geological insights into a Neanderthal symbolic accumulation of large crania

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Des‐Cubierta Cave, part of the Calvero de la Higuera complex, is situated in the intramountainous upper valley of the Lozoya River within the Guadarrama Range. The cave's geological, palaeontological, and archaeological record reveals a complex history of sedimentary and anthropogenic processes spanning hundreds of thousands of years ...

Reliable Methodology for Measuring SERS Enhancement Factor on Colloidal and Solid Substrates: A Practical Guide

open access: yesJournal of Raman Spectroscopy, EarlyView.
A recent literature survey shows that the SERS community is still far from a consensus on how to correctly estimate the Enhancement Factor (EF) of plasmonic substrates. With this article, a simple practical procedure to evaluate the EF of commonly studied colloidal and solid SERS substrates is presented, and all the critical aspects for doing so are ...

Ecogenomics and limnological dynamics of a new Thiocapsa species blooming in the whole water column of a karstic lake

open access: yesLimnology and Oceanography, EarlyView.
Abstract Purple sulfur bacteria (PSB) of the family Chromatiaceae (Gammaproteobacteria) can perform chemo‐ and photo‐lithoautotrophy (through anoxygenic photosynthesis) in anoxic layers of freshwater stratified (including meromictic) lakes. This group has been extensively studied via physiological and ecological approaches, albeit their genomics has ...
