Observation of Gravity Wave Vertical Propagation through a Mesospheric Inversion Layer

open access: yesAtmosphere, 2022
The impact of a mesospheric temperature inversion on the vertical propagation of gravity waves has been investigated using OH airglow images and ground-based Rayleigh lidar measurements carried out in December 2017 at the Haute-Provence Observatory (OHP,

Circulation patterns of the temperature inversion in Tabriz city using PCA [PDF]

open access: yesنشریه جغرافیا و برنامه‌ریزی, 2020
Introduction Today, one of the most important issues in the field of climatology is air pollution and its relationship to the general circulation of the atmosphere. The atmosphere around the planet Earth is made up of gases called fixed atmosphere gases.

Investigation of the MOST channel conductance in weak inversion [PDF]

open access: yes, 1973
The drain-source conductance of several MOS transistors has been studied as a function of the silicon surface-potential ψs in the weak and intermediate inversion region, under the condition of quasi-thermal equilibrium at room temperature.

Comparative analysis of high-temperature targets retrieved from SWIR and TIR data

open access: yesFrontiers in Environmental Science
IntroductionForest fires, grassland fires, heap coking, straw burning, and volcanic eruptions are thermal anomalies. They attract attention and are designated as high-temperature targets.

An Extremely Sparse Tomography Reconstruction of a Multispectral Temperature Field without Any a Priori Knowledge

open access: yesSensors
When undertaking optical sparse projection reconstruction, the reconstruction of the tested field often requires the utilization of a priori knowledge to compensate for the lack of information due to the sparse projection angle.

Surprises from quenches in long-range-interacting systems: temperature inversion and cooling

open access: yesNew Journal of Physics, 2016
What happens when one of the parameters governing the dynamics of a long-range interacting system of particles in thermal equilibrium is abruptly changed (quenched) to a different value?

A precise inversion method of cable joint core temperature with non-embedded detection based on UMAP and ISSA-BPNN

open access: yesFrontiers in Energy Research, 2022
Obtaining the core temperature of the cable joint is vital to ensure the safe operation of the modern power system with integration. To improve the speed and accuracy of core temperature inversion, this study proposed a non-embedded cable joint ...

Raman signatures of inversion symmetry breaking and structural phase transition in type-II Weyl semimetal MoTe2

open access: yes, 2016
Transition metal dichalcogenide MoTe$_2$ is an important candidate for realizing the newly predicted type-IIWeyl fermions, for which the breaking of the inversion symmetry is a prerequisite. Here we present direct spectroscopic evidence for the inversion
