Graph-theoretic properties of inversion-transpositions
Electronic Journal of Graph Theory and ApplicationsDénés established the connection between labeled trees in Graph Theory and factorizations of cyclic permutations by means of transpositions. In this paper, we introduce the notion of an inversion-transposition, which has both the properties of an ...

CYCLIC PERMUTATIONS IN KAZAMA-SUZUKI STRING MODELS [PDF]
International Journal of Modern Physics A, 1995 Moddings by cyclic permutation symmetries are performed on four-dimensional strings, built from N=2 coset models of the type CPm=SU(m+1)/[SU(m)×U(1)]. For some illustrative cases, the massless chiral and antichiral states of E6 are computed. The extent of the equivalence between different conformal invariant theories which possess equal chiral rings ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Endo-permutation modules as sources of simple modules. [PDF]
, 2003 The source of a simple $kG$-module, for a finite $p$-solvable group $G$ and an algebraically closed field $k$ of prime characteristic $p$, is an endo-permutation module (see~\cite{Pu1} or~\cite{Th}). L.

Permutation groups, simple groups and sieve methods
, 2005 We show that the number of integers n ≤ x which occur as indices of subgroups of nonabelian finite simple groups, excluding that of An-1 in An, is ∼ hx/log x, for some given constant h.

Endotrivial modules in the cyclic case. [PDF]
, 2007 The purpose of this note is to determine all endotrivial modules in prime characteristic~$p$, for a finite group having a cyclic Sylow $p$-subgroup.

Encrypting Multiple Images With an Enhanced Chaotic Map
IEEE Access, 2022 A multiple-image encryption scheme based on an enhanced chaotic map is proposed. This scheme combines multiple grayscale images into three planes. An amplified sine map is used to generate a dynamic permutation table and a chaotic sequence.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Developing a linear algorithm for cubing a cyclic permutation
, 1988 A linear algorithm is developed for cubing a cyclic permutation stored as a function in an array. This continues work discussed in [1] and [2] on searching for disciplined methods for developing and describing algorithms that deal with complicated data ...

Vincular pattern avoidance on cyclic permutations
Enumerative Combinatorics and Applications, 2021 Pattern avoidance for permutations has been extensively studied, and has been generalized to vincular patterns, where certain elements can be required to be adjacent. In addition, cyclic permutations, i.e., permutations written in a circle rather than a line, have been frequently studied, including in the context of pattern avoidance.
