The planar Cayley graphs are effectively enumerable I: consistently planar graphs [PDF]

, 2019
We obtain an effective enumeration of the family of finitely generated groups admitting a faithful, properly discontinuous action on some 2-manifold contained in the sphere.

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 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 ...

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)]

Enumerations including laconic enumerators

Theoretical Computer Science, 2017
Abstract We show that it is possible, for every machine universal for Kolmogorov complexity, to enumerate the lexicographically least description of a length n string in O ( n ) attempts. In contrast to this positive result for strings, we find that, in any Kolmogorov numbering, no enumerator of nontrivial size can generate a list containing

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.
