COSMOLOGIES, SINGULARITIES AND QUANTUM EXTREMAL SURFACES

Cosmologies, singularities and quantum extremal surfaces

Abstract Following [1], we study quantum extremal surfaces in various families of cosmologies with Big-Crunch singularities, by extremizing the generalized entropy in 2-dimensional backgrounds which can be thought of as arising from dimensional reduction.Focussing first on the isotropic AdS Kasner case, introducing a spatial regulator enables relat

Comparative Analysis for Titanium alloy and Silicon Nitride (Si3N4) of Thermal Analysis for Deep Groove Ball Bearing

In this paper, the analysis of the directional heat flux and total heat flux for the bearing balls of Titanium alloy and Silicon Nitride has Wraps been demonstrated across a temperature range between 150 to 250 degree celcius.The obtained data allowed comparing the values of total heat flux and various directional heat flux.By comparing directional

Construction of a High-Density Linkage Map and QTL Fine Mapping for Growth- and Sex-Related Traits in Channel Catfish (Ictalurus punctatus)

A high-density genetic linkage map is of particular importance in the fine mapping for important economic traits and whole genome assembly in aquaculture species.The channel catfish (Ictalurus punctatus), a species native to North America, is one of the most important commercial freshwater fish in the world.Outside of the United States, China has b
