Matching expert range maps with species distribution model predictions. [PDF]
Abstract Species’ range maps based on expert opinion are a critical resource for conservation planning. Expert maps are usually accompanied by species descriptions that specify sources of internal range heterogeneity, such as habitat associations, but these are rarely considered when using expert maps for analyses.

The EM Method in a Probabilistic Wavelet-Based MRI Denoising. [PDF]
Human body heat emission and others external causes can interfere in magnetic resonance image acquisition and produce noise. In this kind of images, the noise, when no signal is present, is Rayleigh distributed and its wavelet coefficients can be approximately modeled by a Gaussian distribution.

Morse–Radó theory for minimal surfaces
Abstract For a class of functions (called minimal Radó functions) that arise naturally in minimal surface theory, we bound the number of interior critical points (counting multiplicity) in terms of the boundary data and the Euler characteristic of the domain of the function.

Purely coclosed G2‐structures on nilmanifolds
Abstract We classify seven‐dimensional nilpotent Lie groups, decomposable or of nilpotency step at most 4, endowed with left‐invariant purely coclosed G2‐structures. This is done by going through the list of all seven‐dimensional nilpotent Lie algebras given by Gong, providing an example of a left‐invariant 3‐form φ which is a pure coclosed G2 ...

Abstract In this paper we give a complete answer to a question posed by Dimca and Greuel about the quotient of the Milnor and Tjurina numbers of a plane curve singularity. We put this question into a general framework of the study of the difference of Milnor and Tjurina numbers for isolated complete intersection singularities showing its connection ...

This article examines “soft facts” about security issues in the 2016 Brexit referendum campaign. Soft facts arise when information provenance is uncertain, and are forms of malleable and contingent knowledge, such as rumors, conspiracy theories, and propaganda.

La distancia imposible entre el «cap» derridiano y la «polis» heideggeriana
En este texto se desarrolla un estudio de la noción «cap» en Derrida en confrontación con el modo en que Heidegger presenta la «polis» en sus textos elaborados entre 1935 y 1943.

La anorexia y la bulimia a la luz del grafo del deseo de Lacan
En este texto tratamos los problemas de alimentación a la luz de lo que en términos lacanianos se conoce como el grafo del deseo. Este data de los años 1958-59, cuando Lacan impartió su seminario sobre El deseo y su interpretación, actualmente publicado
