Environment-dependent regime of longevity selection in the chromosomally polymorphic species Leptysma argentina (Acrididae: Orthoptera)
(University Florence Botany Institute, 2012-09)
In previous papers it was reported that a Robertsonian translocation (centric fusion) affected external phenotype in the grasshopper Leptysma argentina and that thorax height was the target of adult viability selection. ...
Frequency-dependent selection predicts patterns of radiations and biodiversity
(Public Library of Science, 2010-08)
Most empirical studies support a decline in speciation rates through time, although evidence for constant speciation rates also exists. Declining rates have been explained by invoking pre-existing niches, whereas constant ...
CHARACTERIZATION OF A SUB-MM WAVE FREQUENCY SELECTIVE SURFACE ON A PERIODICALLY PERFORATED SILICON SUBSTRATE
(Progress In Electromagnetics Research M., 2012)
A penalized time-frequency band feature selection and classification procedure for improved motor intention decoding in multichannel EEG
(IOP Publishing, 2019-02)
Objective. Motor imagery brain-computer interfaces (MI-BCIs) based on electroencephalography (EEG), a promising technology to provide assistance and support rehabilitation of neurological patients with sensorimotor ...
Biometry of stomata in Blechnum species (Blechnaceae) with some taxonomic and ecological implications for the ferns
(Universidad de Costa Rica, 2011)
Edge-preserving frequency-offset denoising of seismic data
(Society of Exploration Geophysicists, 2018-09)
We have developed new algorithms for denoising 2D or 3D poststack seismic-amplitude data that use simple edge-preserving smoothing operators in the frequency-offset domain. The algorithms are aimed to attenuate random and ...
Harmonic Disturbance Rejection Control for Magnetic Field Compensation Applications
(Planta Piloto de Ingeniería Química, 2013-08)
A simple control strategy was studied for harmonic disturbance rejection in magnetic field compensation systems for low-field magnetic resonance techniques. The strategy is based on the simultaneous action of a conventional ...
Human genomic regions with exceptionally high levels of population differentiation identified from 911 whole-genome sequences
(BioMed Central, 2016-06-30)
Population differentiation has proved to be effective for identifying loci under geographically localized positive selection, and has the potential to identify loci subject to balancing selection. We have previously ...
Acoustic Event Classification using spectral band selection and Non-Negative Matrix Factorization-based features
(Elsevier Ltd, 2016)
Feature extraction methods for sound events have been traditionally based on parametric representations specifically developed for speech signals, such as the well-known Mel Frequency Cepstrum Coefficients (MFCC). However, ...
