Anticipation via canards in excitable systems
Köksal Ersöz, E.; Desroches, M.
; Mirasso, C.; Rodrigues, S. (2019-01-14)
Neurons can anticipate incoming signals by exploiting a physiological mechanism that is not well understood. This article offers a novel explanation on how a receiver neuron can predict the sender’s dynamics in a ... -
Application of Quantum Natural Language Processing for Language Translation
(2021-01-01)In this paper, we develop compositional vector-based semantics of positive transitive sentences using quantum natural language processing (Q-NLP) to compare the parametrized quantum circuits of two synonymous simple sentences ... -
Are Brain-Computer Interfaces Feasible withIntegrated Photonic Chips?
Salari, V.; Rodrigues, S.; Saglamyurek, E.; Simon, C.; Oblak, D. (2021-11)
The present paper examines the viability of a radically novel idea for brain-computer interface (BCI), which could lead to novel technological, experimental and clinical applications. BCIs are computer-based systems that ... -
Classification of bursting patterns: A tale of two ducks
Desroches, M.; Rinzel, J.; Rodrigues, S. (2022-01-20)
Bursting is one of the fundamental rhythms that excitable cells can generate either in response to incoming stimuli or intrinsically. It has been a topic of intense research in computational biology for several decades. ... -
Computing Higher Leray–Serre Spectral Sequences of Towers of Fibrations
Guidolin, A.; Romero, A. (2020-10-27)
The higher Leray–Serre spectral sequence associated with a tower of fibrations represents a generalization of the classical Leray–Serre spectral sequence of a fibration. In this work, we present algorithms to compute higher ... -
Computing Multipersistence by Means of Spectral Systems
Guidolin, A.; Divasón, J.; Romero, A.; Vaccarino, F. (2019-07-08)
In their original setting, both spectral sequences and persistent homology are algebraic topology tools defined from filtrations of objects (e.g. topological spaces or simplicial complexes) indexed over the set Z of integer ... -
Conductance-Based Refractory Density Approach for a Population of Bursting Neurons
Chizhov, A.; Campillo, F.; Desroches, M.; Guillamon A; Rodrigues, S. (2019)
The conductance-based refractory density (CBRD) approach is a parsimonious mathematical-computational framework for modeling interact- ing populations of regular spiking neurons, which, however, has not been yet extended ... -
The Euler characteristic as a topological marker for outbreaks in vector-borne disease
Barros de Souza, D.; Figueiroa dos Santos, E.; A N Santos, F. (2022-12-01)
Abstract. Epidemic outbreaks represent a significant concern for the current state of global health, particularly in Brazil, the epicentre of several vector-borne disease outbreaks and where epidemic control is still a ... -
Fock-space approach to stochastic susceptible-infected-recovered models
Barros de Souza, D.; Araújo, H.; Duarte-Fillho, G.; Gaffney, E.; Nóbrega Santos, F.; Raposo, E. (2022-07-25)
We investigate the stochastic susceptible-infected-recovered (SIR) model of infectious disease dynamics in the Fock-space approach. In contrast to conventional SIR models based on ordinary differential equations for the ... -
Geometry of spiking patterns in early visual cortex: A topological data analytic approach
Guidolin, A.; Desroches, M.; Victor, J. D.; Purpura, K. P.; Rodrigues, S. (2022-11-16)
In the brain, spiking patterns live in a high-dimensional space of neurons and time. Thus, determining the intrinsic structure of this space presents a theoretical and experimental challenge. To address this challenge, we ... -
Grigorchuk-Gupta-Sidki groups as a source for Beauvile surfaces
(2020-04-14)If $G$ is a Grigorchuk-Gupta-Sidki group defined over a $p$-adic tree, where p is an odd prime, we study the existence of Beauville surfaces associated to the quotients of $G$ by its level stabilizers $st_G(n)$. We prove ... -
Hyperactivation of monocytes and macrophages in MCI patients contributes to the progression of Alzheimer's disease
Munawara, U.; Catanzaro, M.; Xu, W.; Tan, C.; Hirokawa, K.; Bosco, N.; Dumoulin, D.; Khalil, A.; Larbi, A.; Lévesque, S.; Ramassamy, C.; Barron, A.; Cunnane, S.; Beauregard, P.; Bellenger, J.P.; Rodrigues, S.; Desroches, M.; Witkowski, J.M.; Laurent, B.; Frost, E.; Fülöp, T. (2021-12-01)
Background: Alzheimer’s disease (AD) is the most common neurodegenerative disease ultimately manifesting as clinical dementia. Despite considerable effort and ample experimental data, the role of neuroinflammation related ... -
Immunosenescence and Altered Vaccine Efficiency in Older Subjects: A Myth Difficult to Change
Fülöp, T.; Larbi, A.; Pawelec, G.; Cohen, A.; Provost, G.; Khalil, A.; Lacombe, G.; Rodrigues, S.; Desroches, M.; Hirokawa, K.; Franceschi, C.; Witkowski, J.M. (2022-04-01)
Organismal ageing is associated with many physiological changes, including differences in the immune system of most animals. These differences are often considered to be a key cause of age-associated diseases as well as ... -
