Thermoelectric Processes of Quantum Normal‐Superconductor Interfaces

open access: yesAnnalen der Physik, Volume 537, Issue 11, November 2025.
Recent advances on using mesoscopic normal‐superconductor junctions for the thermoelectric effect is reviewed. A theoretical framework is presented for multiterminal configurations exploiting properties characterised by the interplay of the system reduced dimensionality and superconducting correlations.

Cosmic Ray Counting Variability From Water‐Cherenkov Detectors as a Proxy of Stratospheric Conditions in Antarctica

open access: yesEarth and Space Science, Volume 12, Issue 11, November 2025.
Abstract This work examines atmospheric effects on cosmic ray counts observed by a Water‐Cherenkov detector at the Argentine Antarctic Marambio Station. We analyze the influence of ground‐level barometric pressure and geopotential height at various pressure levels on daily particle rates, finding the strongest association at 100 hPa, linked to ...

Quasi‐Constant Time Gap in Multiple Rings of Elves

open access: yesEarth and Space Science, Volume 12, Issue 10, October 2025.
Abstract We present evidence that the time delay between the multiple rings of elves is not caused by the ground reflection of the electromagnetic pulse produced by intracloud lightning. To investigate temporal differences of multi‐elves, we analyzed data from four storms occurring at various times and distances from the Pierre Auger Observatory in ...

DINÁMICA DE CLUSTERS DE VACANCIAS EN SILICIO

open access: yesAnales (Asociación Física Argentina), 2007
Se estudia la dinámica de aglomerados de vacancias en Silicio utilizando un modelo computacional en la aproximación del continuo. El modelo considera que las vacancias, generadas por activación térmica o por irradiación, pueden difundir y agruparse ...

Inferring single neuron properties in conductance-based balanced networks

open access: yesFrontiers in Computational Neuroscience, 2011
Balanced states in large networks are a usual hypothesis for explaining the variability of neural activity in cortical systems. These states give rise to a generic behavior in which the individual dynamics of the neurons is almost irrelevant.

Adverse impact of acute Toxoplasma gondii infection on human spermatozoa

open access: yesThe FEBS Journal, Volume 292, Issue 17, Page 4720-4736, September 2025.
Toxoplasma gondii tachyzoites injected intraperitoneally crossed the blood‐testes barrier, appearing in testes/epididymis by day 6 post‐infection. In vitro exposure caused increased sperm necrosis/apoptosis and structural damage to heads/tails. Immunofluorescence and SEM revealed tachyzoites attaching to sperm tails, inducing twisting/detachment, and ...

ESTUDIO COMPARATIVO DE LA ADSORCIÓN DE S SOBRE Au(111) y Ag(111) CON XPS, AES, TOF-DRS y LEED

open access: yesAnales (Asociación Física Argentina), 2014
En este trabajo se estudia la adsorción de S sobre la superficie (111) de los metales nobles Au y Ag mediante las técnicas XPS, AES, LEED y TOF-DRS. A pesar de las similitudes de las superficies, todas las técnicas revelan comportamientos diferentes ...
