Including the Magnitude Variability of a Signal in the Ordinal Pattern Analysis [PDF]
EntropyOne of the most popular and innovative methods to analyse signals is by using Ordinal Patterns (OPs). The OP encoding is based on transforming a (univariate) signal into a symbolic sequence of OPs, where each OP represents the number of permutations ...

A signature-agnostic test for differences between tumor mutation spectra reveals carcinogen and ancestry effects [PDF]
Communications BiologyDespite dozens of tools to identify mutational signatures in cancer samples, there is not an established metric for quantifying whether signature exposures differ significantly between two heterogeneous groups of samples.

Circularly permuted variants of two CG-specific prokaryotic DNA methyltransferases. [PDF]
PLoS ONE, 2018 The highly similar prokaryotic DNA (cytosine-5) methyltransferases (C5-MTases) M.MpeI and M.SssI share the specificity of eukaryotic C5-MTases (5'-CG), and can be useful research tools in the study of eukaryotic DNA methylation and epigenetic regulation.

Cyclic Partitions of Complete and Almost Complete Uniform Hypergraphs
Discussiones Mathematicae Graph Theory, 2022 We consider cyclic partitions of the complete k-uniform hypergraph on a finite set V, minus a set of s edges, s ≥ 0. An s-almost t-complementary k-hypergraph is a k-uniform hypergraph with vertex set V and edge set E for which there exists a permutation ...

Self-complementing permutations of k-uniform hypergraphs [PDF]
Discrete Mathematics & Theoretical Computer Science, 2009 Graphs and Algorithms A k-uniform hypergraph H = ( V; E) is said to be self-complementary whenever it is isomorphic with its complement (H) over bar = ( V; ((V)(k)) - E). Every permutation sigma of the set V such that sigma(e) is an edge of (H) over bar if and only if e is an element of E is called self-complementing.

-partite self-complementary and almost self-complementary -uniform hypergraphs
AKCE International Journal of Graphs and Combinatorics, 2020 A hypergraph is said to be -partite -uniform if its vertex set can be partitioned into non-empty sets so that every edge in the edge set , consists of precisely one vertex from each set , . It is denoted as or if for .

Complementation and Reconstitution of Fluorescence from Circularly Permuted and Truncated Green Fluorescent Protein [PDF]
Biochemistry, 2009 Green fluorescent protein (GFP) has been used as a proof of concept for a novel "leave-one-out" biosensor design in which a protein that has a segment omitted from the middle of the sequence by circular permutation and truncation binds the missing peptide and reconstitutes its function.

Statistics on ordered partitions of sets [PDF]
, 2019 We introduce several statistics on ordered partitions of sets, that is, set partitions where the blocks are permuted arbitrarily. The distribution of these statistics is closely related to the q-Stirling numbers of the second kind. Some of the statistics
