Anorectal Dysfunction in Systemic Sclerosis: Clinical Phenotypes and Functional Patterns
Arthritis Care &Research, EarlyView.Objective The aim of this study was to characterize specific physiologic defects in anorectal dysfunction in systemic sclerosis (SSc) using anorectal manometry (ARM), evaluate associations with gastrointestinal (GI) and extraintestinal clinical phenotypes, and explore potential serologic markers for risk stratification.

Oxygen diffusion in oxide crystals - tracing new routes to identify the rate limiting step of oxygen permeation through perovskite membranes [PDF]
, 2005 Perovskites are known as mixed electric conductors because they show both electronic (via electron holes) and ionic (via oxygen vacancies) conductivity. Since the electron conductivity is orders of magnitude higher than the ionic one, oxygen vacancy bulk

On the Origin of Phase Angle in Warburg Finite Length Diffusion Impedance
International Journal of Electrochemical Science, 2019 We develop a simple physical model which describes the origin of phase angle of the Warburg finite length diffusion impedance. We show that diffusion results in a phase delay of the surface concentration of species with respect to current.

dynoGP: Deep Gaussian Processes for Dynamic System Identification
International Journal of Adaptive Control and Signal Processing, EarlyView.This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Reduction of boron diffusion in silicon-germanium by fluorine implantation
, 2004 This paper investigates the effect of a 185 keV, 2.3×1015cm-2 F+ implant on boron thermal diffusion and boron transient enhanced diffusion (TED) in SiGe by characterising the diffusion of a boron marker layer in samples with and without a 288 keV, 6 ...

Effect of Annealing Treatment on Microstructure of Mg/Cu Diffusion Layer
MATEC Web of Conferences, 2016 The experimental study of the “mosaic type” Mg/Cu diffusion couple in the argon protection environment was carried out. The microstructure and micro-hardness of the Mg/Cu diffusion layer were analyzed by means of SEM, EDS and micro-hardness tester.

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...
