Bianchi type-I cosmological models with variable G and Λ-term in general relativity [PDF]
Einstein’s field equations with variable gravitational and cosmological “constant” are considered in presence of perfect fluid for Bianchi type-I space-time. Consequences of the four cases of the phenomenological decay of Λ have been discussed which are consistent with observations.

Fractalkine (FKN) is a chemokine able to mediate the initial capture, firm adhesion, and activation of circulating leukocytes. Many tissues express FKN mRNA and FKN expression is increased during inflammatory conditions.

Modern aspects of convexity and the interplay between geometry and analysis [PDF]
In this thesis, we explore the interactions between geometry and analysis in the world of convex geometry. In particular, we mix techniques from the world of convex and functional analysis together with some from non-smooth differential geometry, finding

First Report of a Severe Outbreak of Aujeszky’s Disease in Cattle in Sicily (Italy)
Aujeszky’s disease in cattle is caused by Suid herpes virus 1. The natural infection has been reported worldwide in bovine species and it is related to direct and indirect contact with infected pigs, which represent the main reservoir of the virus. Here,

Holographic dark energy in Gauss-Bonnet gravity with Granda-Oliveros cut-off
In this paper, we have studied a model of holographic dark energy (HDE) with a homogeneous and anisotropic Bianchi type-I Universe in the framework of Gauss-Bonnet (GB) gravity or f(G) gravity.

Effective Classification using a small Training Set based on Discretization and Statistical Analysis [PDF]
This work deals with the problem of producing a fast and accurate data classification, learning it from a possibly small set of records that are already classified. The proposed approach is based on the framework of the so-called Logical Analysis of Data

Rapid communication. New incursions of West Nile virus lineage 2 in Italy in 2013: the value of the entomological surveillance as early warning system [PDF]
West Nile virus (WNV) is one of the most serious public health threats that Europe and the Mediterranean countries are currently facing. In Italy, WNV emerged in 1998 and has been circulating since 2008.
