Point clouds provide a flexible geometric representation suitable for countless applications
in computer graphics; they also comprise the raw output of most 3D data acquisition devices. …

We propose a simple analytic representation of the correlation energy ɛ c for a uniform
electron gas, as a function of density parameter rs and relative spin polarization ζ. Within the …

Currently, there are no approved specific antiviral agents for novel coronavirus disease 2019
(COVID-19). In this study, 10 severe patients confirmed by real-time viral RNA test were …

Inflammatory caspases (caspase-1, -4, -5 and -11) are critical for innate defences. Caspase-1
is activated by ligands of various canonical inflammasomes, and caspase-4, -5 and -11 …

The discovery of the enhancement of Raman scattering by molecules adsorbed on nanostructured
metal surfaces is a landmark in the history of spectroscopic and analytical techniques. …

For a uniform electron gas of density n= n↑+ n↓= 3/4π rs 3= π ks 6/192 and spin polarization
ζ=(n↑-n↓)/n, we study the Fourier transform ρ c (k, rs, ζ) of the correlation hole, as well as …

The focus of recent meta-learning research has been on the development of learning
algorithms that can quickly adapt to test time tasks with limited data and low computational cost. …

We construct a generalized gradient approximation (GGA) for the density n xc (r, r+u) at
position r+u of the exchange-correlation hole surrounding an electron at r, or more precisely for …

The electronic exchange energy as a functional of the density may be approximated as E x [n]=
A x∫ d 3 rn 4 3 F (s), where s=|∇ n| 2 k F n, k F=(3 π 2 n) 1 3, and F (s)=(1+ 1.296 s 2+ …

Metal-halide perovskites have rapidly emerged as one of the most promising materials of
the 21st century, with many exciting properties and great potential for a broad range of …
