Combinatorial families of multilabelled increasing trees and hook-length formulas [PDF]

, 2014
In this work we introduce and study various generalizations of the notion of increasingly labelled trees, where the label of a child node is always larger than the label of its parent node, to multilabelled tree families, where the nodes in the tree can ...

Isolation of probiotics and nutritional evaluation of fermented lactose-free foods as a potential treatment for diarrhoea

Croatian Journal of Food Science and Technology, 2021
Probiotics are live bacteria that can be found in fermented local foods and confer health benefits on the host when administered in adequate amounts. However, there is little awareness of local fermented, lactose-free foods as good and cheap sources of ...

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.

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 ...

Lattice Enumeration with Discrete Pruning: Improvements, Cost Estimation and Optimal Parameters

Mathematics, 2023
Lattice enumeration is a linear-space algorithm for solving the shortest lattice vector problem (SVP). Extreme pruning is a practical technique for accelerating lattice enumeration, which has a mature theoretical analysis and practical implementation ...

Enumeration of simple random walks and tridiagonal matrices

, 2002
We present some old and new results in the enumeration of random walks in one dimension, mostly developed in works of enumerative combinatorics. The relation between the trace of the $n$-th power of a tridiagonal matrix and the enumeration of weighted ...

A Hybrid Intelligence Approach for Circulating Tumor Cell Enumeration in Digital Pathology by Using CNN and Weak Annotations

IEEE Access, 2023
Counting the number of Circulating Tumor Cells (CTCs) for cancer screenings is currently done by cytopathologists with a heavy time and energy cost. AI, especially deep learning, has shown great potential in medical imaging domains. The aim of this paper

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.

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.
