Using Selective Memoization to Defeat Regular Expression Denial of Service (ReDoS)

Abstract: Regular expressions (regexes) are a denial of service vector in most mainstream programming languages. Recent empirical work has demonstrated that up to 10% of regexes have super-linear ...

Converting Regular Expressions to Non-Deterministic Finite Automata through an Automated Framework

Abstract: A Regular Expression, often abbreviated as Regex, are a sequence of characters that define a search pattern. An Non-deterministic Finite Automata (NFA) is a computational machine which can ...

A python package collecting an assortment of Geometric Phase Analysis algorithms and tools to analyse regular (moiré) lattices.

Geometric Phase Analysis enables the extraction of a displacement field from a distorted lattice, by comparing to reference waves. As such, it is a spatial variant of lock-in amplification. This ...

Regular expression example not clear.

Using the data shown, it is not clear the difference between using "X" vs. "^X" as both results are the same. With the ^ the search picks up the X at the beginning of the line at position 6. With no ^ ...
