Invertibility properties of matrix wiener‐hopf plus Hankel integral operators

open access: yesMathematical Modelling and Analysis, 2008
We consider matrix Wiener‐Hopf plus Hankel operators acting between Lebesgue spaces on the real line with Fourier symbols presenting some even properties (which in particular include unitary matrix‐valued functions), and also with Fourier symbols which ...

Data fusion of gamma and x‐ray spectra via Common Dimensions for soil erosion characterization

open access: yesSoil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract This study explores the synergistic application of energy dispersive x‐ray fluorescence (EDXRF) and gamma‐ray spectrometry (GRS) raw spectra to characterize soil redistribution. The evaluation employs Common Dimensions (ComDim), a multiblock non‐supervised machine‐learning technique, to identify shared latent patterns across nuclear and atomic

Long‐term jaguar demography underscores the ecological value of Amazonian floodplains

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our results provide the first estimates of recruitment and apparent survival for Amazonian jaguars, key parameters for guiding conservation. We show that seasonal wetlands—the Amazonian floodplain forest and reported estimates from Pantanal and the Llanos—harbour the highest jaguar densities across the species' range.

Environmental detection of the amphibian chytrid fungus in water bodies is associated with host infection along a deforestation gradient

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
Linking environmental pathogen detection with host infection patterns can improve surveillance of diseases involving environmental transmission, particularly where direct host sampling is logistically challenging. This approach enables the identification of areas of elevated transmission risk and supports targeted monitoring and management under ...

R 2 inflation to probe non-perturbative quantum gravity

open access: yesJournal of High Energy Physics, 2018
It is natural to expect a consistent inflationary model of the very early Universe to be an effective theory of quantum gravity, at least at energies much less than the Planck one. For the moment, R + R 2, or shortly R 2, inflation is the most successful
