Electronic Structure Calculations with the Exact Pseudopotential and Interpolating Wavelet Basis

open access: yesAtoms, 2023
Electronic structure calculations are mostly carried out with Coulomb potential singularity adapted basis sets such as STO or contracted GTO. With another basis or for heavy elements, the pseudopotentials may appear as a practical alternative.

Recovering low‐rank tensor from limited coefficients in any ortho‐normal basis using tensor‐singular value decomposition

open access: yesIET Signal Processing, 2021
Tensor singular value decomposition (t‐SVD) provides a novel way to decompose a tensor. It has been employed mostly in recovering missing tensor entries from the observed tensor entries.

On the dynamical basis of the classification of normal galaxies [PDF]

open access: yesProceedings of the National Academy of Sciences, 1982
Some realistic galaxy models have been found to support discrete unstable spiral modes. Here, through the study of the relevant physical mechanisms and an extensive numerical investigation of the properties of the dominant modes in a wide class of galactic equilibria, we show how spiral structures are excited with different morphological features ...

Short Rational Functions for Toric Algebra and Applications [PDF]

open access: yes, 2003
We encode the binomials belonging to the toric ideal $I_A$ associated with an integral $d \times n$ matrix $A$ using a short sum of rational functions as introduced by Barvinok \cite{bar,newbar}.

Self-Dual Normal Basis of a Galois Ring

open access: yesJournal of Mathematics, 2014
Let R′=GR(ps,psml) and R=GR(ps,psm) be two Galois rings. In this paper, we show how to construct normal basis in the extension of Galois rings, and we also define weakly self-dual normal basis and self-dual normal basis for R′ over R, where R′ is ...

Design of elliptic curve cryptoprocessors over GF(2^163) using the Gaussian normal basis

open access: yesIngeniería e Investigación, 2014
This paper presents the efficient hardware implementation of cryptoprocessors that carry out the scalar multiplication kP over finite field GF(2163) using two digit-level multipliers. The finite field arithmetic operations were implemented using Gaussian

Complementary congruent and opposite neurons achieve concurrent multisensory integration and segregation

open access: yeseLife, 2019
Our brain perceives the world by exploiting multisensory cues to extract information about various aspects of external stimuli. The sensory cues from the same stimulus should be integrated to improve perception, and otherwise segregated to distinguish ...

Structural basis of the regulation of the normal and oncogenic methylation of nucleosomal histone H3 Lys36 by NSD2

open access: yesNature Communications, 2021
An upregulation of NSD2, a histone H3 lysine 36 (H3K36) methyltransferase is linked to multiple myeloma and other types of cancer. Here, the authors provide insights into the regulatory mechanism of NSD2 by determining the 2.8 Å cryo-EM structure of the ...
