Anharmonic behavior in Microwave-driven resistivity oscillations in Hall bars

open access: yes, 2007
We analyzed the magnetoresistivity of a two-dimensional electron system excited by microwave radiation in a regime of high intensities and low frequencies. In such a regime, recent experiments show that different features appear in the magnetoresistivity

Review of Frequency Response Analysis for Testing of Rotating Electric Machines

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
Active research on evaluating the feasibility of applying frequency response analysis for maintenance testing and quality assurance of rotating machines and components has been performed over the last 7–8 years. The purpose of this article is to provide a summary and critical analysis of the latest research published on the application of frequency ...

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

Physiological Plasticity of Neural-Crest-Derived Stem Cells in the Adult Mammalian Carotid Body [PDF]

open access: yes, 2017
Adult stem cell plasticity, or the ability of somatic stem cells to cross boundaries and differentiate into unrelated cell types, has been amatter of debate in the last decade.

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

Observation of pair tunneling and coherent destruction of tunneling in arrays of optical waveguides [PDF]

open access: yes, 2016
We report on the experimental realization of a photonic system that simulates the one-dimensional two-particle Hubbard model. This analogy is realized by means of two-dimensional arrays of coupled optical waveguides, fabricated using femtosecond laser ...

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.

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.

Turn-to-turn fault protection technique for synchronous machines without additional voltage transformers [PDF]

open access: yes, 2017
This paper presents a novel protection technique for the detection of inter-turn faults in synchronous machines. It is based on the calculation of voltage in the stator windings from the usual phases and neutral voltage, typically available in ...
