Proposal for a ferromagnetic multiwell spin oscillator

open access: yes, 2010
The highly nonlinear coupling of transport and magnetic properties in a multiwell heterostructure, which comprises ferromagnetic quantum wells made of diluted magnetic semiconductors, is theoretically investigated. The interplay of resonant tunneling and

Localization of interacting electrons in quantum dot arrays driven by an ac-field [PDF]

open access: yes, 2004
We investigate the dynamics of two interacting electrons moving in a one-dimensional array of quantum dots under the influence of an ac-field. We show that the system exhibits two distinct regimes of behavior, depending on the ratio of the strength of ...

Children's agencies navigating sexism and LGBTI+ phobia in Santiago de Chile's primary school

open access: yesChildren &Society, Volume 40, Issue 1, Page 132-149, January 2026.
Abstract Through their talk, actions and interactions, children actively shape and develop notions of gender and sexuality. This research delves into the realm of children's agency to explore the ways children act and react to instances of sexism and LGBTI+ phobia.

Hall magnetoresistivity response under Microwave excitation revisited

open access: yes, 2007
We theoretically analyzed the microwave-induced modification of the Hall magnetoresistivity in high mobility two-dimensional electron systems. These systems present diagonal magnetoresistivity oscillations and zero-resistance states when are subjected to

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 ...

Polarization immunity of magnetoresistivity response under Microwave excitation

open access: yes, 2007
We analyze theoretically the dependence of the microwave polarization sate and sense on the magnetoresistivity response of two-dimensional electron systems. Linear and circular polarization have been considered with different senses and directions.

Electron-Photon interaction in resonant tunneling diodes

open access: yes, 1997
We develope a model to describe the transmission coefficient and tunneling current in the presence of photon-electron coupling in a resonant diode. Our model takes into account multiphoton processes as well as the transitions between electronic states ...

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.

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 ...

Platero en ek

open access: yesTydskrif vir Letterkunde, 2017
Platero and ek deur Juan Ramón Jiménez, die 1956-wenner van die Nobelprys vir letterkunde, word gewoonlik gesien as ’n boek vir kinders. Dit word in elk geval as sodanig in die boekhandel bemark.
