, 2013 Today many bug detecting tools use static program analysis techniques to discover the vulnerabilities in programs, and many static program analyses can be converted to CFL (Context-Free-Language) reachability problems, most of which are Dyck-CFL ...

The area above the Dyck path of a permutation
, 2010 In this paper we study a mapping from permutations to Dyck paths. A Dyck path gives rise to a (Young) diagram and we give relationships between statistics on permutations and statistics on their corresponding diagrams.

New Formulas for Dyck Paths in a Rectangle [PDF]
, 2015 We consider the problem of counting the set of $\mathscr{D}_{a,b}$ of Dyck paths inscribed in a rectangle of size $a\times b$. They are a natural generalization of the classical Dyck words enumerated by the Catalan numbers. By using Ferrers diagrams associated to Dyck paths, we derive formulas for the enumeration of $\mathscr{D}_{a,b}$ with $a$ and $b$

Counting Peaks at Height k in a Dyck Path
, 2002 of steps (1; 1) and (1; 1), which never passes below the x-axis. A peak at height k on a Dyck path is a point on the path with coordinate y = k that is immediately preceded by a (1; 1) step and immediately followed by a (1; 1) step.

Physiological Entomology, EarlyView.Partial replacement of Brewer's yeast (protein source) with inactivated Enterobacter biomass during larval development enhanced mating competitiveness of sterile VIENNA 8 GSS males under outdoor field‐cage conditions. Sterile male mating performance was season‐dependent, with highest competitiveness in spring, intermediate in autumn and the lowest ...

Intervals in Dyck Paths and the Wreath Conjecture
The Electronic Journal of CombinatoricsLet $\iota_{k}(m,l)$ denote the total number of intervals of length $m$ across all Dyck paths of semilength $k$ such that each interval contains precisely $l$ falls. We give the formula for $\iota_{k}(m,l)$ and show that $\iota_{k}(k,l)=\binom{k}{l}^2$.

Science Needs for a Terrestrial Biosphere Tipping Point Early Warning System
Reviews of Geophysics, Volume 64, Issue 4, December 2026.Abstract Tipping points in the Earth system have the potential to cause major detrimental impacts to the biosphere and societies. Their inherent nonlinearity implies that even relatively small additional increases in external forcing might result in disproportionately large adjustments to components of the Earth system.

On \({k}\)-Dyck Paths with a Negative Boundary
Journal of Combinatorial Mathematics and Combinatorial ComputingPaths that consist of up-steps of one unit and down-steps of \(k\) units, being bounded below by a horizontal line \(-t\), behave like \(t+1\) ordered tuples of \(k\)-Dyck paths, provided that \(t\le k\). We describe the general case, allowing \(t\) also to be larger. Arguments are bijective and/or analytic.
