Bianchi type-I cosmological models with variable G and Λ-term in general relativity [PDF]
Astrophysics and Space Science, 2008 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.

First Report of a Severe Outbreak of Aujeszky’s Disease in Cattle in Sicily (Italy)
Pathogens, 2020 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,

Tunable Oxygen Connectivity in Carbaporphyrinoid Polymers on Metal Surfaces
Angewandte Chemie, EarlyView.Hydroxyl‐functionalized dicarbaporphyrinoid polymers synthesized on Au(111) enable tunable oxygen‐mediated connectivity under UHV conditions. Thermal activation yields one‐dimensional hydroxyl‐terminated polymers that can selectively evolve into either covalently‐linked dibenzo‐p‐dioxane architectures through intermolecular C–O–C coupling or two‐fold ...

Holographic dark energy in Gauss-Bonnet gravity with Granda-Oliveros cut-off
Nuclear Physics B, 2022 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.

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]
Veterinaria Italiana, 2013 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.
