e-Vocabulary and e-Learning [PDF]

open access: yesEducation Sciences, 2017
A vocabulary is a linguistic resource that helps manage, query and retrieve information and/or knowledge via words. If vocabularies are built and used in electronic format, they are referred as e-vocabularies. E-vocabularies have been used in Education to help teachers and students to, amongst many issues, (1) comprehend and relate the concepts and the

Search for K+ decays into the π+e+e−e+e− final state

open access: yesPhysics Letters B, 2023
The first search for ultra-rare $K^+$ decays into the $\pi^+e^+e^-e^+e^-$ final state is reported, using a dataset collected by the NA62 experiment at CERN in 2017-2018. An upper limit of $1.4\times 10^{-8}$ at 90% CL is obtained for the branching ratio of the $K^+\to\pi^+e^+e^-e^+e^-$ decay, predicted in the Standard Model to be $(7.2\pm0.7)\times 10^{

CD4+ T Cell Depletion during all Stages of HIV Disease Occurs Predominantly in the Gastrointestinal Tract

open access: yesJournal of Experimental Medicine, 2004
The mechanisms underlying CD4+ T cell depletion in human immunodeficiency virus (HIV) infection are not well understood. Comparative studies of lymphoid tissues, where the vast majority of T cells reside, and peripheral blood can potentially illuminate ...

Similar songs, but different mate localization strategies of the three species of Phaneroptera occurring in Western Europe (Orthoptera: Phaneropteridae)

open access: yesEuropean Journal of Entomology, 2021
In bush-crickets, males produce a calling song to announce their presence to females. Females ready to mate respond either by a phonotactic approach or signal their presence acoustically by establishing a kind of duet.
