Understanding the support dynamics for LGBTI+ youth in Spain during and after the COVID‐19 pandemic

open access: yesChildren &Society, Volume 40, Issue 1, Page 183-203, January 2026.
Abstract This qualitative study explores the experiences of LGBTI+ youth in Spain during the COVID‐19 pandemic, focusing on family, social, educational and healthcare support mechanisms. The findings, based on five focus groups, highlight the pivotal role of family support during the pandemic, increased isolation and a reliance on online connections ...

Spin entangled two-particle dark state in quantum transport through coupled quantum dots

open access: yes, 2013
We present a transport setup of coupled quantum dots that enables the creation of spatially separated spin-entangled two-electron dark states. We prove the existence of an entangled transport dark state by investigating the system Hamiltonian without ...

Microscopic derivation of transport coefficients and boundary conditions in discrete drift-diffusion models of weakly coupled superlattices

open access: yes, 2000
A discrete drift-diffusion model is derived from a microscopic sequential tunneling model of charge transport in weakly coupled superlattices provided temperatures are low or high enough.

Hierarchy of Floquet gaps and edge states for driven honeycomb lattices [PDF]

open access: yes, 2015
Electromagnetic driving in a honeycomb lattice can induce gaps and topological edge states with a structure of increasing complexity as the frequency of the driving lowers.

Targeting ecto‐5′‐nucleotidase (CD73) and cAMP alleviates carotid body hyperactivity and reduces blood pressure in chronically hypoxic rats

open access: yesThe Journal of Physiology, Volume 604, Issue 1, Page 626-652, 1 January 2026.
Abstract figure legend CD73 promotes carotid body hyperactivity in chronically hypoxic animals. Exposure to chronic hypoxia (CH) (FiO2 of 12% for 10 days) increases the proportion of CD73+TH+ cells in the carotid body and induces basal chemoafferent hyperactivity.

Nuclear-spin-induced localization of the edge states in two-dimensional topological insulators [PDF]

open access: yes, 2017
We investigate the influence of nuclear spins on the resistance of helical edge states of two-dimensional topological insulators (2DTIs). Via the hyperfine interaction, nuclear spins allow electron backscattering, otherwise forbidden by time reversal ...

Label‐Free Characterization of Lipid Interfaces Using Plasmonic Gold Nanorods as Optically Active Nanosensors

open access: yesAdvanced Optical Materials, Volume 13, Issue 34, December 2, 2025.
A label‐free plasmonic nanosensor platform is presented based on single gold nanorods for the nanometric characterization of lipid interfaces. By correlating optical scattering signals with membrane packing and refractive index, this approach enables the detection of gel‐to‐fluid transitions in lipid interfaces, offering a robust, high‐resolution ...

La judería y sinagoga de Coria en la documentación del Archivo Catedralicio: siglos XIV y XV

open access: yesSefarad : Revista de Estudios Hebraicos y Sefardíes, 2001
La comunidad judía de Coria se remonta a fines del siglo XII. La judería estaba en la calle y plaza del Albaicín, en la colación de Santa María, y la sinagoga en la plaza de San Juan. En la judería vivían aproximadamente unas 46 familias que se dedicaron
