Sums of Digits, Overlaps, and Palindromes [PDF]
Discrete Mathematics & Theoretical Computer Science, 2000 Let s_k(n) denote the sum of the digits in the base-k representation of n. In a celebrated paper, Thue showed that the infinite word (s_2(n) \bmod 2)_n≥ 0 is \emphoverlap-free, i.e., contains no subword of the form axaxa where x is any finite word and a ...

Optical Genome Mapping Identifies a Second Xq27.1 Rearrangement Associated With Charcot-Marie-Tooth Neuropathy CMTX3. [PDF]
Mol Genet Genomic MedBackground X‐linked recessive type 3 Charcot–Marie–Tooth (CMTX3) is a rare subtype of childhood‐onset CMT. To date, all reported CMTX3 patients share a common founder 78 kb insertion from chromosome 8 into the Xq27.1 palindrome region.

Longest Gapped Repeats and Palindromes [PDF]
Discrete Mathematics & Theoretical Computer Science, 2017 A gapped repeat (respectively, palindrome) occurring in a word $w$ is a factor $uvu$ (respectively, $u^Rvu$) of $w$. In such a repeat (palindrome) $u$ is called the arm of the repeat (respectively, palindrome), while $v$ is called the gap. We show how to

A complete comparison for the number of palindromes in different bases
AIMS Mathematics, 2023 Let $ b $ and $ b_1 $ be distinct positive integers larger than $ 1 $, and let $ A_{b} (n) $ and $ A_{b_1} (n) $ be the number of palindromes in bases $ b $ and $ b_1 $ that are less than or equal to $ n $, respectively.

Extremal orders and races between palindromes in different bases
AIMS Mathematics, 2022 Let $ b \geq 2 $ and $ n \geq 1 $ be integers. Then $ n $ is said to be a palindrome in base $ b $ (or $ b $-adic palindrome) if the representation of $ n $ in base $ b $ reads the same backward as forward.

Semantics and Pragmatics of Palindromes in Language and Internet Communication
Научный диалог, 2021 The semantic and pragmatic features of palindromes are considered as an important component of the Russian linguistic picture of the world. The question of establishing the scope and boundaries of the concept of “palindrome” is raised, the specificity of

Palindromic Vectors, Symmetropy and Symmentropy as Symmetry Descriptors of Binary Data
Entropy, 2022 Today, the palindromic analysis of biological sequences, based exclusively on the study of “mirror” symmetry properties, is almost unavoidable. However, other types of symmetry, such as those present in friezes, could allow us to analyze binary sequences
