Comparison of four agar media for the enumeration of the Mycobacterium abscessus complex

International Journal of Mycobacteriology, 2020
Background: Traditional culture of nontuberculous mycobacteria (NTMs) has involved egg-based formulations (Lowenstein–Jensen medium) or defined media (Middlebrook formulations), which have disadvantages of composition complexity, availability, and cost ...

Specific cultivation-independent enumeration of viable cells in probiotic products using a combination of fluorescence in situ hybridization and flow cytometry

Frontiers in Microbiology
This study introduces an optimized integration of flow cytometry and fluorescence in situ hybridization (Flow-FISH) as an approach for the specific enumeration of gram-positive bacteria in probiotic products, overcoming the limitations of conventional ...

Optimization of Viability Treatment Essential for Accurate Droplet Digital PCR Enumeration of Probiotics

Frontiers in Microbiology, 2020
Improvements offered by viability droplet digital PCR (v-ddPCR) include increased precision, specificity and decreased time to results making for an attractive alternative method to traditional plate count enumeration of probiotic products.

Enumeration of Hypergraphs

European Journal of Combinatorics, 2001
Formulas for the cycle index of the representation of the symmetric group of degree \(n\) acting on all subsets of the object set are derived and applied through \(n=7\). These can be used to enumerate hypergraphs with Pólya's enumeration theorem. The approach is similar to that of \textit{E. M. Palmer} [Discrete Math. 6, 377-390 (1973; Zbl 0269.05110)]

Enumerating polytropes

Journal of Combinatorial Theory, Series A, 2017
Polytropes are both ordinary and tropical polytopes. We show that tropical types of polytropes in $\mathbb{TP}^{n-1}$ are in bijection with cones of a certain Gröbner fan $\mathcal{GF}_n$ in $\mathbb{R}^{n^2 - n}$ restricted to a small cone called the polytrope region.

Enumeration of dissociation sets in grid graphs

AIMS Mathematics
A dissociation set of a graph $ G $ refers to a set of vertices inducing a subgraph with maximum degree at most 1 and serves as a generalization of two fundamental concepts in graph theory: Independent sets and induced matchings.

A simple recurrence formula for the number of rooted maps on surfaces by edges and genus [PDF]

Discrete Mathematics & Theoretical Computer Science, 2014
We establish a simple recurrence formula for the number $Q_g^n$ of rooted orientable maps counted by edges and genus. The formula is a consequence of the KP equation for the generating function of bipartite maps, coupled with a Tutte equation, and it was

Enumerating the rationals

Journal of Functional Programming, 2006
We present a series of programs for enumerating the rational numbers without duplication, drawing on some elegant results of Neil Calkin, Herbert Wilf and Moshe Newman.
