Holographic phase transition from novel Gauss–Bonnet AdS black holes

European Physical Journal C: Particles and Fields, 2020
In the framework of holography, we discuss on the phase transition behavior from a novel Gauss–Bonnet AdS black hole discovered in [Phys. Rev. Lett. 124, 081301 (2020)] in both charged and neutral cases.

Hungarian neutral vowels [PDF]

, 2013
In Hungarian, stems containing only front unrounded (neutral) vowels fall into two groups: one group taking front suffixes, the other taking back suffixes in vowel harmony. The distinction is traditionally thought of as purely lexical.

Formation of Neutral Disk-Like Zone Around the Active Hot Stars in Symbiotic Binaries

Open Astronomy, 2012
In this contribution we present the ionization structure in the enhanced wind from the hot star in symbiotic binaries during active phases. Rotation of the hot star leads to the compression of the outflowing material towards its equatorial plane.

Influence of Relative Spatial Layout of Fire and Openings on Neutral Plane Characteristics and Distribution Mechanisms of Mass and Heat Release for Spill Plumes in Compartment Fires

Fire
This paper presents a numerical investigation into full-scale double-opening compartment fires. It aims to reveal the underlying mechanisms by which the relative spatial layout of the fire source and openings influences neutral plane characteristics ...

Neutrality of coated holes in the presence of screw dislocation dipoles or circular thermal inclusions

Archives of Mechanics, 2018
In this paper, we consider the design of neutral coated holes in two particular cases when the thick coating itself is altered by the presence of some form of material imperfection.
