Differentially 4-Uniform Permutations with the Best Known Nonlinearity from Butterflies

open access: yesIACR Transactions on Symmetric Cryptology, 2017
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

open access: yesJournal of Statistical Software, 2017
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.

End-to-End Neural Speaker Diarization with Permutation-Free Objectives [PDF]

open access: yesInterspeech, 2019
In this paper, we propose a novel end-to-end neural-network-based speaker diarization method. Unlike most existing methods, our proposed method does not have separate modules for extraction and clustering of speaker representations.

Minimax optimality of permutation tests [PDF]

open access: yesAnnals of Statistics, 2020
Permutation tests are widely used in statistics, providing a finite-sample guarantee on the type I error rate whenever the distribution of the samples under the null hypothesis is invariant to some rearrangement.

Encryption of Stereo Image Based on Fractional Chaotic System and RNA Encoding

open access: yesTaiyuan Ligong Daxue xuebao, 2021
For the increasingly wide usage of stereo images, a stereo image encryption algorithm based on fractional-order hyper-chaotic system and dynamic Ribonucleic Acid (RNA) encoding was proposed. In the chaotic sequence generation stage, SHA-256 hash function

Common permutation methods in animal social network analysis do not control for non-independence

open access: yesbioRxiv, 2021
The non-independence of social network data is a cause for concern among behavioural ecologists conducting social network analysis. This has led to the adoption of several permutation-based methods for testing common hypotheses.

The art of permutation in John Ashbery’s strata poetry

open access: yesCogent Arts & Humanities, 2023
This study intends to explore the art of permutation in John Ashbery’s stratum poetry, which is entopic in the majority and incremented in some. Through his permutation, Ashbery developed his unique poetry voice and expressed apothegms relevant to his ...

Operators of equivalent sorting power and related Wilf-equivalences [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
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.
