Logarithmic Sobolev Inequality for Zero-Range Dynamics: independence of the number of particles

open access: yes, 2004
We prove that the logarithmic-Sobolev constant for Zero-Range Processes in a box of diameter L may depend on L but not on the number of particles. This is a first, but relevant and quite technical step, in the proof that this logarithmic-Sobolev constant

Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.

Quantification of entanglement via uncertainties [PDF]

open access: yes, 2007
We show that entanglement of pure multi-party states can be quantified by means of quantum uncertainties of certain basic observables through the use of measure that has been initially proposed in [10] for bipartite systems.Comment: Changed content ...

High β‐diversity in fig wasp communities driven by species turnover in widely distributed Neotropical fig trees

open access: yesOikos, EarlyView.
Wasp communities associated with fig trees, Ficus spp., are a model system to investigate how local and regional processes shape biodiversity across large geographical ranges. We investigated the β‐diversity of fig wasp assemblages associated with three widely distributed Neotropical fig species – F. citrifolia, F. obtusifolia and F. pertusa – using 27

Potential of bacteria isolated from chitin‐enriched soil against Euschistus heros (Hemiptera: Pentatomidae)

open access: yesPest Management Science, EarlyView.
B. thuringiensis and B. altitudinis, isolated from chitin‐enriched soil, causing mortality in Euchistus heros under laboratory conditions. First report of B. altitudinis in the control of E. heros. Abstract BACKGROUND Biological control using entomopathogenic microorganisms is a more sustainable alternative to chemical pesticides for managing insect ...

Magnus expansion method for two-level atom interacting with few-cycle pulse

open access: yes, 2017
Using the Magnus expansion to the fourth order, we obtain analytic expressions for the atomic state of a two-level system driven by a laser pulse of arbitrary shape with small pulse area.

An improved phylogeny and revised taxonomy of Catillariaceae (Lecanoromycetes, Ascomycota)

open access: yesTAXON, EarlyView.
Abstract The boundaries of the family Catillariaceae have largely remained untested through phylogenetic methods. Recent studies have led to the transfer of several genera previously classified in Catillariaceae to the newly described family Leprocaulaceae. Despite these changes, the distinction between Catillariaceae, Leprocaulaceae, and Catinariaceae
