Studies in artificially confined, small-scale experimental systems with a homogeneous prey distribution suggest
that selectivity in planktivorous fish for more conspicuous and rewarding prey (such as...
On spatial selectivity and prediction across conditions with fMRI
Machine learning fMRI feature selection regions
2012/11/22
Researchers in functional neuroimaging mostly use activation coordinates to formulate their hypotheses. Instead, we propose to use the full statistical images to define regions of interest (ROIs). Thi...
A spatio-temporal Gaussian-Conical wavelet with high aperture selectivity for motion and speed analysis
Extraction of motion parameters speed tuning continuous wavelet transform directional and conical wavelets
2012/5/25
The construction of a spatio-temporal wavelet and its tuning to speed was first realized in the 90s on the Morlet wavelet by M. Duval-Destin \cite{Duval-Destin91a,Duval-Destin92}. This enabled to demo...
Vapor phase alkylation of toluene using various alcohols over H3PO4/MCM-41 catalyst: influence of reaction parameters on selectivity and conversion
