A Bound of Fast Algebraic Immunity of Constructions With BPR Using a Four-Disjoint-Part Support

open access: yesIEEE Access, 2020
Boolean functions are used for stream cipher ought to be a high fast algebraic immunity (FAI) to effectively against fast algebraic attacks. In the previous research methods, there is no suitable method to gain the FAI of Boolean functions using ...

Bound on optimal local discrimination of multipartite quantum states

open access: yesScientific Reports, 2022
We consider the unambiguous discrimination of multipartite quantum states and provide an upper bound for the maximum success probability of optimal local discrimination. We also provide a necessary and sufficient condition to realize the upper bound.

Upper bound on minimal length from deuteron

open access: yesResults in Physics, 2014
We calculate the correction to the deuteron quadrupole moment induced by generalized uncertainty principle (GUP) and find an upper bound on the minimal length.

Maximum common subgraph: some upper bound and lower bound results

open access: yesBMC Bioinformatics, 2006
Background Structure matching plays an important part in understanding the functional role of biological structures. Bioinformatics assists in this effort by reformulating this process into a problem of finding a maximum common subgraph between graphical

Horn Upper Bounds and Renaming [PDF]

open access: yes, 2007
We consider the problem of computing tractable approximations to CNF formulas, extending the approach of Selman and Kautz to compute the Horn-LUB to involve renaming of variables. Negative results are given for the quality of approximation in this extended version.

An upper bound for the dimension of bounded derived categories [PDF]

open access: yesJournal of Algebra, 2020
Let $Λ$ be an artin algebra. We give an upper bound for the dimension of the bounded derived category of the category $\mod Λ$ of finitely generated right $Λ$-modules in terms of the projective and injective dimensions of certain class of simple right $Λ$-modules as well as the radical layer length of $Λ$.

An upper bound for ramsey numbers

open access: yesApplied Mathematics Letters, 2004
The Ramsey number, \(r(G,H)\) of the graphs \(G\) and \(H\) is the smallest integer \(N\) such that every colouring of the edges of \(K_N\) with red and blue yields either a red \(G\) or a blue \(H\). The Erdős-Szekeres recursion theorem yields \(r(G,H)\leq r(G',H)+r(G,H')\), where \(G'\) is a graph obtained by deleting one vertex from \(G\).

The Euclidean Steiner Ratio and the measure of chirality of biomacromolecules

open access: yesGenetics and Molecular Biology, 2004
The study of Euclidean Steiner Trees is one of the alternative methods to unveil Nature's plans for the internal architecture of biomacromolecules. Recently, the minimum surface structure of the A-DNA and of the Tobacco Mosaic Virus was shown to be ...

Upper Bound Limit Stability Analysis for Soil Slope with Nonuniform Multiparameter Distribution Based on Discrete Algorithm

open access: yesAdvances in Civil Engineering, 2020
Slope stability analysis is a core issue in geotechnical engineering. This paper proposes a method of upper bound limit stability analysis for a slope with multiparameter coordinated variation based on the comprehensive consideration of the nonuniform ...
