Encrypting Multiple Images With an Enhanced Chaotic Map

open access: yesIEEE 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.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS 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.

Han’s bijection via permutation codes [PDF]

open access: yes, 2010
We show that Han’s bijection when restricted to permutations can be carried out in terms of the cyclic major code and the cyclic inversion code. In other words, it maps a permutation π with cyclic major code (s1,s2,…,sn) to a permutation σ with cyclic ...

Vincular pattern avoidance on cyclic permutations

open access: yesEnumerative 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.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Timed Event Graph-based Scheduling for Cyclic Permutation Flow Shop [PDF]

open access: yes, 2008
The cyclic permutation flow shop is one flow shop that repetitively produces product mix under permutation schedules. We propose that the cyclic permutation flow shop given the general job sequence can be modeled as a time event graph, based on which the

A permutation-generating algorithm [PDF]

open access: yes, 1990
This paper gives an algorithm generating all elements of the symmetric group Sn ordered as a sequence of cosets of Sn/G, where G is a subgroup of order 2n (for n ⩾ 3) generated by cyclic permutation C: i → + 1 (mod n) and the reversal permutation R: i ...

On a problem of cyclic permutations of integers

open access: yesDiscrete Applied Mathematics, 1980
AbstractWe consider a problem of cyclic permutations of integers arising in the field of memory technologies for computer systems, and we solve it in the more general case of reals.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
