Stochastic Resonance and Dynamic First-Order Pseudo-Phase Transitions in the Irreversible Growth of Thin Films under Spatially Periodic Magnetic Fields
Article
Article
Loscar, Ernesto Selim et al · American Physical Society · 2013 · ISSN 2470-0053
We study the irreversible growth of magnetic thin films under the influence of spatially periodic fields by means of extensive Monte Carlo simulations. We find first-order pseudo-phase transitions that separate a dynamic...

Stochastic resonance and brownian ratchets
Article
Article
Fendrik, Alejandro J. et al · RI ITBA · 2018 · ISSN 0378-4371
"We discuss the connections between Brownian ratchets (BR) and stochastic resonance (SR). We consider a periodic potential energy landscape with no left–right symmetry that is driven by an external force which can be ...

On the effect of noise and electronics bandwidth on a stochastic-resonance memory device
Text / resource
Text / resource
Fierens, Pablo Ignacio et al · RI ITBA · 2017 · ISSN 0094-243X
"We recently showed that a ring of two bistable oscillators is capable of storing a single bit of information via stochastic resonance. Memory performance was characterized in terms of the probability of erroneous bit de...

On the dynamics of a single-bit stochastic-resonance memory device
Article
Article
Ibáñez, Santiago Agustín et al · RI ITBA · 2011 · ISSN 1434-6036
"The increasing capacity of modern computers, driven by Moore’s Law, is accompanied by smaller noise margins and higher error rates. In this paper we propose a memory device, consisting of a ring of two identical overd...

Time delay properties of stochastics-resonance information transmission line
Article
Article
Ibáñez, Santiago Agustín et al · RI ITBA · 2019 · ISSN 0219-4775
"In this paper we analyze the properties of a chain of forward-coupled bi-stable over-damped oscillators. It is well known that this system displays stochastic resonance and behaves as a transmission line when an adequat...

Characterization of Otto Chips by Particle Swarm Optimization
Article
Article
Adonias Luna Pereira da Silva et al · Sociedade Brasileira de Microondas e Optoeletrônica e Sociedade Brasileira de Eletromagnetismo · 2021 · ISSN 2179-1074
Abstract Recently a surface plasmon resonance (SPR) optical sensor, based on the Otto configuration — the Otto chip — has been developed. One essential step in the quality control of the fabrication process is charac...

Acceleration noise induced decoherence in Stern-Gerlach interferometers for gravity experiments
Article
Article
Meng-Zhi Wu · American Physical Society · 2026 · ISSN 2643-1564
Stern-Gerlach interferometer (SGI) is a kind of matter-wave interferometer driven by magnetic field and has been proposed for various gravity experiments. Stochastic noises can lead to decoherence problems of SGI via var...

Segmentation of brain MR images through a hidden Markov random field model and the expectation-maximization algorithm
Article
Article
Y. Zhang; Michael Brady; Stephen M. Smith · IEEE Transactions on Medical Imaging · 2001
The finite mixture (FM) model is the most commonly used model for statistical segmentation of brain magnetic resonance (MR) images because of its simple mathematical form and the piecewise constant nature of ideal brain ...
