How a dc Electric Field Drives Mott Insulators out of Equilibrium
(American Physical Society, 2018-07)
Out of equilibrium phenomena are a major issue of modern physics. In particular, correlated materials such as Mott insulators experience fascinating long-lived exotic states under a strong electric field. Yet, the origin ...
Selective activation of memristive interfaces in TaOx-based devices by controlling oxygen vacancies dynamics at the nanoscale
(IOP Publishing, 2020-01)
The development of novel devices for neuromorphic computing and non-traditional logic operations largely relies on the fabrication of well controlled memristive systems with functionalities beyond standard bipolar behavior ...
Oxygen vacancies dynamics in redox-based interfaces: Tailoring the memristive response
(IOP Publishing, 2019-09)
Redox-based memristive devices are among the alternatives for the next generation of non-volatile memories, but also candidates to emulate the behavior of synapses in neuromorphic computing de- vices. Nowadays it is well ...
Implementação de redes neurais por pulsos a partir de sinapses memristivas
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA ELÉTRICAPrograma de Pós-Graduação em Engenharia ElétricaUFMG, 2022-05-20)
Artificial intelligence (AI) applications are increasingly present and necessary, especially neural networks (NN). The limited scalability of CMOS (complementary metal-oxide-semiconductor) technology and the increasing ...
The impact of the suppression of highly connected protein interactions on the corona virus infection
(Nature, 2022)
Several highly effective Covid-19 vaccines are in emergency use, although more-infectious coronavirus strains, could delay the end of the pandemic even further. Because of this, it is highly desirable to develop fast ...
Hardware implementation of a retinal model [recurso electrónico]
(2012-11-09)
Diseases that degenerate retinal neural cells cause loss of vision because the retina converts light into electrical pulses and performs the first processing stages of the neural visual signals. Thus, the considerable ...
Modeling of charge transport for an artificial synapse based on magnetic Josephson junctions
(Universidad de los AndesFísicaFacultad de CienciasDepartamento de Física, 2018)
In this work we study the modelling of charge transport through a magnetic Josephson junction device with potential application in Neuromorphic computing as a synapse device; the artificial synapse was proposed by Schneider ...
Effective thickness dependence on charge carrier transport in electrolyte-gated organic field-effect transistors
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Física e AstronomiaUTFPR, 2022-02-01)
Organic field-effect transistors (OFETs) began to be studied in the 1980s. Since then, several studies have focused on improving the performance of these organic devices, investigating transport properties of conjugated ...
On the thermal models for resistive random access memory circuit simulation
(MDPI AG, 2021-05)
Resistive Random Access Memories (RRAMs) are based on resistive switching (RS) operation and exhibit a set of technological features that make them ideal candidates for applications related to non-volatile memories, ...
FAS -670A>G promoter polymorphism is associated with soluble Fas levels in primary Sjögren's syndrome
(2004)
A previous paper introduced a model of architecture called Neuromorphic Autonomous Controller (NAC) conformed by interconnected modules, each one in charge of growing its own network of cells. The integration of all internal ...
