As we know, improving security is one of the most important motivations for designing new image encryption schemes. However, the security of some new image encryption schemes has not been fully analyzed and evaluated.

PerMallows: An R Package for Mallows and Generalized Mallows Models
In this paper we present the R package PerMallows, which is a complete toolbox to work with permutations, distances and some of the most popular probability models for permutations: Mallows and the Generalized Mallows models.

Statistical dependence and shape of Young tableau
Given two continuous random variables, X and Y, we study the relationship between their statistical dependence and the Young tableau of the permutation defined from the graph of a bivariate sample coming from (X, Y). From a sample of size n of (X, Y), we

Differentially 4-Uniform Permutations with the Best Known Nonlinearity from Butterflies
Many block ciphers use permutations defined over the finite field F22k with low differential uniformity, high nonlinearity, and high algebraic degree to provide confusion. Due to the lack of knowledge about the existence of almost perfect nonlinear (APN)

GFD: An R Package for the Analysis of General Factorial Designs
Factorial designs are widely used tools for modeling statistical experiments in all kinds of disciplines, e.g., biology, psychology, econometrics and medicine. For testing null hypotheses in this framework, ANOVA methods are widely used.

Bogdanov Map-based Permuted Double Image Encryption [PDF]
Chaos-based image encryption schemes shuffle the position of the pixels (confuse), change their values (diffuse), to camouflage the identity of the original image.

Phenolic Compounds and Skin Permeability: An In Silico Investigation [PDF]
Background: The skin is the largest organ of the body and provides the main barrier between the internal and external environment. Assessment of skin permeability is of critical importance for understanding and predicting in vivo efficacy and ...

Operators of equivalent sorting power and related Wilf-equivalences [PDF]
We study sorting operators $\textrm{A}$ on permutations that are obtained composing Knuth's stack sorting operator \textrmS and the reverse operator $\textrm{R}$, as many times as desired.

Generating trees for partitions and permutations with no k-nestings [PDF]
We describe a generating tree approach to the enumeration and exhaustive generation of k-nonnesting set partitions and permutations. Unlike previous work in the literature using the connections of these objects to Young tableaux and restricted lattice ...
