Spatiotemporal response of neuronal networks to time-dependent spectral features
(American Institute of Physics (AIP), 2007-12)
In this work, we analyze the behavior of a neuronal network when it is stimulated by a synaptic train current with variable frequency. Using the fact that resonat (type II) neurons have a preferred input frequency, we ...
Spatio-Temporal Filtering for Evoked Potentials Detection
(Springer, 2020)
We propose the new application of the spatio-temporal filtering (STF) method, which is a detection of visual evoked potentials applied to brain-computer interfaces (BCI). STF aims in creating a new, enhanced channel basing ...
Spatiotemporal determinants of urban leptospirosis transmission: four-year prospective cohort study of slum residents in Brazil.
(Brasil, 2016)
Background: Rat-borne leptospirosis is an emerging zoonotic disease in urban slum settlements for which there are no adequate control measures. The challenge in elucidating risk factors and informing approaches for prevention ...
NO + NH3 reaction over polycrystalline Pt: Numerical analysis of spatio-temporal data and evidence of non-linear behavior
(Elsevier Science, 2013-01)
Surface catalytic reactions display under low pressure conditions non-linear features such as non-stationary reaction rates and spatio-temporal patterns known as dissipative structures. We analyze experimental data from ...
Quasi-one-dimensional waves in rodent populations in heterogeneous habitats: A consequence of elevational gradients on spatio-temporal dynamics
(Elsevier, 2013-02)
Wave propagation can be clearly discerned in data collected on mouse populations in the Cibola National Forest (New Mexico, USA) related to seasonal changes. During an exploration of the construction of a methodology for ...
Diversity of decapod crabs (Crustacea: Brachyura) in two islands of Ubatuba, southeast of Brazil
(2020-01-01)
This is the first comparative study of the alpha and beta diversity of crabs from soft bottom areas nearby two coastal islands (Couves and Mar Virado Islands). Crabs were captured monthly from January 1998 to December 1999. ...
A Depth Video-based Human Detection and Activity Recognition using Multi-features and Embedded Hidden Markov Models for Health Care Monitoring Systems
Increase in number of elderly people who are living independently needs especial care in the form of healthcare monitoring systems. Recent advancements in depth video technologies have made human activity recognition (HAR) ...
Deep-based recurrent approaches for gesture recognition
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE CIÊNCIA DA COMPUTAÇÃOPrograma de Pós-Graduação em Ciência da ComputaçãoUFMG, 2020-06-12)
The recognition of gestures corresponds to a mathematical interpretation of a human motion by a machine. It involves different aspects and parts of human body, such as variations in the positioning of hands and arms, ...
Spatial Distribution of Bat Shelters and Livestock Rabies in Southern Brazil
(2021-10-01)
This study focused on the epidemiological characterization and spatial distribution of bat shelters concerning livestock animal rabies in Paraná State, southern Brazil. A spatiotemporal cluster analysis was performed based ...
