Decomposition of openness [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
In this note weak openness and almost openness are used to develop two decompositions of openness. Two additional conditions related to openness also are developed.

Degeneracies of Triangulated Graphs

open access: yesTheory and Applications of Graphs
A graph $G$ is $k$-degenerate if each subgraph has minimum degree at most $k$. The degeneracy\textbf{ }$D\left(G\right)$ is the smallest $k$ such that $G$ is $k$-degenerate.

In situ studies of the degradation mechanisms of perovskite solar cells

open access: yesEcoMat, 2020
The last decade has seen an extraordinary rise in the performance of perovskite solar cells (PSCs). State‐of‐the‐art devices now have efficiencies of over 25%, putting them on par with the best silicon solar cells.

Spectral proper orthogonal decomposition and its relationship to dynamic mode decomposition and resolvent analysis [PDF]

open access: yesJournal of Fluid Mechanics, 2017
We consider the frequency domain form of proper orthogonal decomposition (POD), called spectral proper orthogonal decomposition (SPOD). Spectral POD is derived from a space–time POD problem for statistically stationary flows and leads to modes that each ...

A Survey of Decomposition Based Evolutionary Algorithms for Many-Objective Optimization Problems

open access: yesIEEE Access, 2022
The framework of decomposition-based multi-objective evolutionary algorithms(MOEA/D) has evolved for more than ten years, and it has become irreplaceable tool for solving multi-objective optimization problems.

Meson Mass Decomposition [PDF]

open access: yes, 2014
Hadron masses can be decomposed as a sum of components which are defined through hadronic matrix elements of QCD operators. The components consist of the quark mass term, the quark energy term, the glue energy term and the trace anomaly term.

Tensor Decomposition for Signal Processing and Machine Learning [PDF]

open access: yesIEEE Transactions on Signal Processing, 2016
Tensors or multiway arrays are functions of three or more indices $(i,j,k,\ldots)$—similar to matrices (two-way arrays), which are functions of two indices $(r,c)$ for (row, column).

On the decomposition of forces

open access: yesTheoretical and Applied Mechanics Letters, 2014
We show that any continuously differentiable force is decomposed into the sum of a Rayleigh force and a gyroscopic force. We also extend this result to piecewise continuously differentiable forces. Our result improves the result on the decomposition of forces in a book by David Merkin and further extends it to piecewise continuously differentiable ...

Estimating and explaining ethnic disparities in the cumulative risk of paternal incarceration in Denmark

open access: yesDemographic Research, 2020
Background: Paternal incarceration is a well-known risk factor for poor child outcomes. Although existing research documents the prevalence of paternal incarceration and racial/ethnic disparities in this risk, research in this area is still sorely ...

On the Parity of Power Permutations

open access: yesIEEE Access, 2021
Side-channel analysis (SCA) attacks and many countermeasures to foil these attacks have been the subject of a large body of research. Different masking schemes have been proposed as countermeasures, one of which is Threshold Implementation (TI), which ...
