arXiv, 2020 Everybody has certainly heard about palindromes: words that stay the same when read backwards. For instance kayak, radar, or rotor. Mathematicians are interested in palindromic numbers: positive integers whose expansion in a certain integer base is a palindrome.

Biotechnology and Bioengineering, EarlyView.ABSTRACT Escherichia coli accumulates acetate as a byproduct in fast growth aerobic conditions when using glucose as carbon source. This phenomenon, known as overflow metabolism, has negative impacts on cell growth and protein expression, also causes carbon loss during biosynthesis in most microbial production scenarios. In this study, we regarded the “

Palindrome Recognition In The Streaming Model [PDF]
arXiv, 2013 In the Palindrome Problem one tries to find all palindromes (palindromic substrings) in a given string. A palindrome is defined as a string which reads forwards the same as backwards, e.g., the string "racecar". A related problem is the Longest Palindromic Substring Problem in which finding an arbitrary one of the longest palindromes in the given ...

Palindromic Decompositions with Gaps and Errors [PDF]
arXiv, 2017 Identifying palindromes in sequences has been an interesting line of research in combinatorics on words and also in computational biology, after the discovery of the relation of palindromes in the DNA sequence with the HIV virus. Efficient algorithms for the factorization of sequences into palindromes and maximal palindromes have been devised in recent

Advances in Isotope Labeling for Solution Nucleic Acid NMR Spectroscopy
ChemPlusChem, Accepted Article.The availability of nucleic acid structural biology methods still lags behind that of proteins, as evidenced by the significantly smaller number of structures deposited in the PDB. The highly skewed ratio of nucleic acid structures, relative to their protein counterparts (~1:50), is inverted with respect to the cellular output of RNA and proteins in ...

Streaming for Aibohphobes: Longest Palindrome with Mismatches [PDF]
arXiv, 2017 A palindrome is a string that reads the same as its reverse, such as "aibohphobia" (fear of palindromes). Given an integer $d>0$, a $d$-near-palindrome is a string of Hamming distance at most $d$ from its reverse. We study the natural problem of identifying a longest $d$-near-palindrome in data streams.

Model‐Informed Drug Development Applications and Opportunities in mRNA‐LNP Therapeutics
Clinical Pharmacology &Therapeutics, EarlyView.The utilization of lipid nanoparticles (LNP) for encapsulating mRNA has revolutionized the field of therapeutics, enabling the rapid development of COVID‐19 vaccines and cancer vaccines. However, the clinical development of mRNA‐LNP therapeutics faces numerous challenges due to their complex mechanisms of action and limited clinical experience.

Interplay Between Bacteriophages and Restriction-Modification Systems in Enterococci
Nova Biotechnologica et Chimica, 2014 The complete genomes of Enterococcus faecalis bacteriophages were analyzed for tetranucleotide words avoidance. Very similar tetranucleotide composition was found in all tested genomes with strong underrepresentation of palindromic GATC and GGCC words ...

Palindromes In Sturmian Strings [PDF]
arXiv, 2010 Let p be a maximal palindrome in a Sturmian word s=ul_1pl_2v so that p is a palindrome and l_1pl_2 is not for letters l_1 and l_2. Let {\alpha}(p,p') be a morphism mapping letters a and b respectively to a^pb and a^p'b, |p-p'|=1. In this paper, we characterize the palindromes in a Sturmian word and show that the number of maximal palindromes in a ...
