Abstract Using a fossilized birth–death model, new phylogeny of the superfamily Evanioidea (including ensign wasps, nightshade wasps and hatchet wasps) is proposed, with estimates divergence times for its constitutive families corroborating monophyly Evanioidea. Additionally, our Bayesian analyses demonstrate †Anomopterellidae, †Othniodellithidae, †Andreneliidae, Aulacidae, Gasteruptiida Evanii...

In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...

Background: Black pepper (Piper nigrum) is mainly cultivated in tropical areas such as South India. It is known as a popular spice in all over the world. Although some studies have been carried out to determine the ingredients of black pepper Essential Oil (EO) cultivated in various regions of the world, but there is little data about some physicochemical characteristics of EO of black pepper c...
