2D Anisotropic Wavelet Entropy with an Application to Earthquakes in Chile
MDPI (2015-06-16)We propose a wavelet-based approach to measure the Shannon entropy in the context of spatial point patterns. The method uses the fully anisotropic Morlet wavelet to estimate the energy distribution at different directions ... -
Multiresolution analysis of linearly oriented spatial point patterns
Taylor & Francis (2015)The assumption of direction invariance, i.e. isotropy, is often made in the practical analysis of spatial point patterns due to simpler interpretation and ease of analysis. However, this assumption is many times hard to ... -
Piezoelectric Control of the Exciton Wave Function in Colloidal CdSe/CdS Nanocrystals
American Chemical Society (2016-05-25)Using multiband k·p calculations, we show that strain-engineered piezoelectricity is a powerful tool to modulate the electron−hole spatial separation in a wide class of wurtzite CdSe/CdS nanocrystals. The inherent ...

Recent advances to model anisotropic space–time data
Springer-Verlag (2008-05)Building new and flexible classes of nonseparable spatio-temporal covariances and variograms has resulted a key point of research in the last years. The goal of this paper is to present an up-to-date overview of recent ...

Spatio-temporal evolution modeling of environmental and natural phenomena
UCLA Department of Statistics (2012)This short paper introduces the special issue containing six selected papers coming from the International Workshop on Spatio-temporal Modeling (METMA V) held in San- tiago de Compostela (Spain), from 30 June to 2 July 2010.
