On the Diamond Bessel Heat Kernel

open access: yesJournal of Applied Mathematics, 2011
We study the heat equation in n dimensional by Diamond Bessel operator. We find the solution by method of convolution and Fourier transform in distribution theory and also obtain an interesting kernel related to the spectrum and the kernel which is ...

Collinear orbital antiferromagnetic order and magnetoelectricity in quasi-two-dimensional itinerant-electron paramagnets, ferromagnets, and antiferromagnets

open access: yesPhysical Review Research, 2020
We develop a comprehensive quantitative theory for magnetoelectricity in magnetically ordered quasi-two-dimensional (quasi-2D) systems whereby in thermal equilibrium an electric field can induce a magnetization and a magnetic field can induce an electric

Smoke from 2020 United States wildfires responsible for substantial solar energy forecast errors

open access: yesEnvironmental Research Letters, 2022
The 2020 wildfire season (May through December) in the United States was exceptionally active, with the National Interagency Fire Center reporting over 10 million acres ( $\gt$ 40 000 km ^2 ) burned.

3D characterisation of tool wear whilst diamond turning silicon [PDF]

open access: yes, 2006
Nanometrically smooth infrared silicon optics can be manufactured by the diamond turning process. Due to its relatively low density, silicon is an ideal optical material for weight sensitive infrared (IR) applications. However, rapid diamond tool edge

Metastable Nanosized Diamond Formation from Fluid Systems [PDF]

open access: yes, 2010
The model of nanosized diamond particles formation at metastable P-T parameters from fluid is presented. It explains the specific of CVD diamond synthesis gases mixtures and hydrothermal growth of diamond at low P-T parameters as well as it explains the ...

Subsampled Sum-Modified-Laplacian for Adaptive Loop Filter in Versatile Video Coding

open access: yesIEEE Access, 2020
This paper proposes a Subsampled Sum-Modified-Laplacian (SSML) operator for the block classification of the Adaptive Loop Filter (ALF) in Versatile Video Coding (VVC). The VVC Test Model (VTM)-2.0 includes Geometry transformation-based ALF (GALF) with 4 &

Conformally soft fermions

open access: yesJournal of High Energy Physics, 2021
Celestial diamonds encode the global conformal multiplets of the conformally soft sector, elucidating the role of soft theorems, symmetry generators and Goldstone modes. Upon adding supersymmetry they stack into a pyramid.
