Boundedness in languages of infinite words
We define a new class of languages of $\omega$-words, strictly extending $\omega$-regular languages. One way to present this new class is by a type of regular expressions.

Minimizing nfa's and regular expressions
AbstractWe show inapproximability results concerning minimization of nondeterministic finite automata (nfa's) as well as of regular expressions relative to given nfa's, regular expressions or deterministic finite automata (dfa's).We show that it is impossible to efficiently minimize a given nfa or regular expression with n states, transitions ...

Tumor necrosis factor gene expression in regular hemodialysis patients
This study evaluates tumor necrosis factor (TNF)-alfa gene expression in patients with end-stage renal disease (ESRD) on regular hemodialysis as an expression of cardiovascular disease (CVD) risk even on a sub-clinical level and its relation to some of ...

Particle motion and collisions around rotating regular black hole
The neutral particle motion around rotating regular black hole that was derived from the Ay\'{o}n-Beato-Garc\'{i}a black hole solution by the Newman-Janis algorithm in the preceding paper [Phys. Rev. D 89, 104017, (2014)] has been studied.

On the Expressive Power of Regular Expressions with Backreferences
A rewb is a regular expression extended with a feature called backreference. It is broadly known that backreference is a practical extension of regular expressions, and is supported by most modern regular expression engines, such as those in the standard libraries of Java, Python, and more.

Deafness mutation mining using regular expression based pattern matching
Background While keyword based queries of databases such as Pubmed are frequently of great utility, the ability to use regular expressions in place of a keyword can often improve the results output by such databases. Regular expressions can allow for the

Automated DNA Motif Discovery [PDF]
Ensembl's human non-coding and protein coding genes are used to automatically find DNA pattern motifs. The Backus-Naur form (BNF) grammar for regular expressions (RE) is used by genetic programming to ensure the generated strings are legal.

New bounds for the max-$k$-cut and chromatic number of a graph
We consider several semidefinite programming relaxations for the max-$k$-cut problem, with increasing complexity. The optimal solution of the weakest presented semidefinite programming relaxation has a closed form expression that includes the largest ...
