Infinite Temperature's Not So Hot

open access: yes, 2022
It has been argued that the entanglement spectrum of a static patch of de Sitter space must be flat, or what is equivalent, the temperature parameter in the Boltzmann distribution must be infinite. This seems absurd: quantum fields in de Sitter space have thermal behavior with a finite temperature proportional to the inverse radius of the horizon.

Contrasting responses of terrestrial ecosystem production to hot temperature extreme regimes between grassland and forest

open access: yes, 2014
. During the past several decades, observational data have shown a faster increase in hot temperature extremes than the change in mean temperature. Increasingly high extreme temperatures are expected to affect terrestrial ecosystem function.

Universal Minimum Heat Leak on Low-Temperature Metallic Electrical Leads

open access: yes, 2006
Low-temperature electronic systems require electrical leads which have low electrical resistance to provide bias current I without excessive voltage drop V. But proper cryogenic design also requires high thermal resistance to maintain a minimum heat leak

Numerical simulation and detection of dry-type air-core reactor temperature field based on laminar–turbulent model

open access: yesAIP Advances, 2021
The hot-spot temperature of a dry-type air-core reactor is a crucial factor that determines the service life of the reactor. Although the environment elevation has a significant influence on the reactor’s heat dissipation performance and hot-spot ...

Pion electromagnetic form factor at finite temperature [PDF]

open access: yes, 1996
Temperature effects on the electromagnetic couplings of pions in hot hadronic matter are studied with an effective chiral Lagrangian. We show that the Ward-Takahashi identity is satisfied at non-zero temperature in the soft pion limit.

PENERAPAN PERSAMAAN GEOTERMOMETER (SiO2)p DI LAPANGAN PANAS BUMI SULI, AMBON

open access: yesBarekeng, 2012
Suli hot springs area has a low level of acidity or neutral pH ranges (7,2–7,7). It is also supported by a high chloride concentration value, which ranges (208,87-226,27) ppm. This shows that the area on station 1, 2, 3, and 4 are located in areas with

Interaction of hot spots and THz waves in Bi_2Sr_2CaCu_2O_8 intrinsic Josephson junction stacks of various geometry

open access: yes, 2010
At high enough input power in stacks of Bi_2Sr_2CaCu_2O8 intrinsic Josephson junctions a hot spot (a region heated to above the superconducting transition temperature) coexists with regions still in the superconducting state.

Decaying Sterile Neutrinos as a Heating Source in the Milky Way Center

open access: yes, 2008
Recent Chandra and Newton observations indicate that there are two-temperature components ($T \sim$ 8 keV, 0.8 keV) of the diffuse x-rays emitted from deep inside the center of Milky Way.

A Method for Hot Spot Temperature Prediction of a 10 kV Oil-Immersed Transformer

open access: yesIEEE Access, 2019
This paper proposed a prediction method to predict a 10-kV oil-immersed transformer hot spot temperature (HST). A set of feature temperature points on the transformer iron shell is proposed based on fluid-thermal field calculation.
