Counting non-isomorphic maximal independent sets of the n-cycle graph [PDF]
, 2007 The number of maximal independent sets of the n-cycle graph C_n is known to be the nth term of the Perrin sequence. The action of the automorphism group of C_n on the family of these maximal independent sets partitions this family into disjoint orbits ...

CRISPR-Cas9 System as a Versatile Tool for Genome Engineering in Human Cells
Molecular Therapy: Nucleic Acids, 2016 Targeted nucleases are influential instruments for intervening in genome revision with great accuracy. RNA-guided Cas9 nucleases produced from clustered regularly interspaced short palindromic repeats (CRISPR)-Cas systems have noticeably altered the ...

On morphisms preserving palindromic richness [PDF]
Fundamenta Informaticae, Volume 185, Issue 1 (March 10, 2022)
fi:7243, 2020 It is known that each word of length $n$ contains at most $n+1$ distinct palindromes. A finite rich word is a word with maximal number of palindromic factors. The definition of palindromic richness can be naturally extended to infinite words. Sturmian words and Rote complementary symmetric sequences form two classes of binary rich words, while ...

Mutagenesis, 1996 To study the structure and mechanism of deletion mutation in human somatic cells in vivo, we have identified and sequenced the breakpoints of 16 independent deletions at the hypoxanthine-guanine phosphoribosyl transferase (HPRT) locus in human T ...

Retrovirology, 2007 Background Retroviruses selectively encapsidate two copies of their genomic RNA, the Gag protein binding a specific RNA motif in the 5' UTR of the genome. In human immunodeficiency virus type 2 (HIV-2), the principal packaging signal (Psi) is upstream of

On Polynomial Pairs of Integers [PDF]
Journal of Integer Sequences, Vol. 18 (2015), Article 15.3.5, 2012 The reversal of a positive integer $A$ is the number obtained by reading $A$ backwards in its decimal representation. A pair $(A,B)$ of positive integers is said to be palindromic if the reversal of the product $A \times B$ is equal to the product of the reversals of $A$ and of $B$.

The numbers of repeated palindromes in the Fibonacci and Tribonacci sequences
, 2016 The Fibonacci sequence $\mathbb{F}$ is the fixed point beginning with $a$ of morphism $ (a,b)=(ab,a)$. Since $\mathbb{F}$ is uniformly recurrent, each factor $ $ appears infinite many times in the sequence which is arranged as $ _p$ $(p\ge 1)$. Here we distinguish $ _p\neq _q$ if $p\neq q$.
