A simple formula for bipartite and quasi-bipartite maps with boundaries [PDF]
We obtain a very simple formula for the generating function of bipartite (resp. quasi-bipartite) planar maps with boundaries (holes) of prescribed lengths, which generalizes certain expressions obtained by Eynard in a book to appear.

Probiotics are universally recognized for their health benefits, despite the fact that their effects depend on the strain. Identification and enumeration of probiotic strains are required prior to evaluating their effectiveness.

Enumeration of octagonal tilings [PDF]
Random tilings are interesting as idealizations of atomistic models of quasicrystals and for their connection to problems in combinatorics and algorithms.

Unlabeled $(2+2)$-free posets, ascent sequences and pattern avoiding permutations [PDF]
We present statistic-preserving bijections between four classes of combinatorial objects. Two of them, the class of unlabeled $(\textrm{2+2})$-free posets and a certain class of chord diagrams (or involutions), already appeared in the literature, but ...

Enumeration of the distinct shuffles of permutations [PDF]
A shuffle of two words is a word obtained by concatenating the two original words in either order and then sliding any letters from the second word back past letters of the first word, in such a way that the letters of each original word remain spelled ...

Enumeration of the Monomials of a Polynomial and Related Complexity Classes [PDF]
We study the problem of generating monomials of a polynomial in the context of enumeration complexity. In this setting, the complexity measure is the delay between two solutions and the total time.

Numeric abstractions relied upon by modern water management are reductive by design, but their political effects need not be reductionist, as an example from Bengaluru attests.

Families of prudent self-avoiding walks [PDF]
A self-avoiding walk on the square lattice is $\textit{prudent}$, if it never takes a step towards a vertex it has already visited. Préa was the first to address the enumeration of these walks, in 1997.

ENUMERATION AS A MEANS OF FINANCIAL MARKETS DATA REPRESENTATION
Cognitive linguistics has developed into one of the most attractive and influential frameworks within linguistics at large. And it draws the linguists’ attention to the study of aspects of language within cognitive paradigm as reflections of conceptual ...
