Robust DNA repair in PAXX-deficient mammalian cells. [PDF]
FEBS Open Bio, 2018 Human HAP1 cells lacking nonhomologous DNA end‐joining (NHEJ) factor PAXX possess robust DNA repair. Murine CH12F3 PAXX‐deficient cells maintain wild‐type levels of class switch recombination to IgA. By contrast, HAP1 cells lacking NHEJ factors XLF or XRCC4 are hypersensitive to DNA damage and possess increased levels of genomic instability compared to

Hosoya properties of the commuting graph associated with the group of symmetries
Main Group Metal Chemistry, 2021 A vast amount of information about distance based graph invariants is contained in the Hosoya polynomial. Such an information is helpful to determine well-known distance based molecular descriptors.

Special Matrices, 2021 We propose an algorithm, which is based on the method given by Kişi and Özdemir in [Math Commun, 23 (2018) 61], to handle the problem of when a linear combination matrix X=∑i=1mciXiX = \sum\nolimits_{i = 1}^m {{c_i}{X_i}} is a matrix such that its ...

Eccentric topological properties of a graph associated to a finite dimensional vector space
Main Group Metal Chemistry, 2020 A topological index is actually designed by transforming a chemical structure into a number. Topological index is a graph invariant which characterizes the topology of the graph and remains invariant under graph automorphism.

Characterizations and representations of left and right hybrid (b, c)-inverses in rings [PDF]
, 2021 Let R be an associative ring with unity 1 and let a, b ,c is an element of R. In this paper, several characterizations for left and right hybrid (b, c)-inverses of a are derived.

Nonlinear anti-commuting maps of strictly triangular matrix Lie algebras
Operators and Matrices, 2019 Let N(F) be the Lie algebra consisting of all strictly upper triangular (n+ 1)× (n+ 1) matrices over a field F . A map φ on N(F) is called to be anti-commuting if [φ(x),y] = −[x,φ(y)] for any x,y ∈ N(F) . We show that for n 4 , a nonlinear map φ : N(F) →

The minimum rank of universal adjacency matrices [PDF]
, 2011 In this paper we introduce a new parameter for a graph called the {\it minimum universal rank}. This parameter is similar to the minimum rank of a graph. For a graph $G$ the minimum universal rank of $G$ is the minimum rank over all matrices of the form \
