Flows and Bisections in Cubic Graphs [PDF]

open access: yesJournal of Graph Theory, 2017
AbstractA k‐weak bisection of a cubic graph G is a partition of the vertex‐set of G into two parts V1 and V2 of equal size, such that each connected component of the subgraph of G induced by () is a tree of at most vertices. This notion can be viewed as a relaxed version of nowhere‐zero flows, as it directly follows from old results of Jaeger that ...

Degradation graphs reveal hidden proteolytic activity in peptidomes. [PDF]

open access: yesPLoS Computational Biology
Protein degradation is a regulated process that reshapes the proteome and generates bioactive peptides. Peptidomics and degradomics enables large-scale measurement of these peptides, yet most data analyses approaches treat peptides as isolated endpoints ...

Pedestrian Flows Analysis to Create a Sustainable Development Concept for a Metropolitan Area [PDF]

open access: yesE3S Web of Conferences, 2023
This article presents the results of structuring the territory adjacent to Pryanishnikov Street in the Timiryazevsky District of the Northern Administrative District of Moscow. The key objects of the street road network that form the pedestrian flows are

Flows on flow-admissible signed graphs [PDF]

open access: yesJournal of Combinatorial Theory, Series B, 2021
In 1983, Bouchet proposed a conjecture that every flow-admissible signed graph admits a nowhere-zero $6$-flow. Bouchet himself proved that such signed graphs admit nowhere-zero $216$-flows and Zyka further proved that such signed graphs admit nowhere-zero $30$-flows. In this paper we show that every flow-admissible signed graph admits a nowhere-zero 11-

Simple graph models of information spread in finite populations [PDF]

open access: yesRoyal Society Open Science, 2015
We consider several classes of simple graphs as potential models for information diffusion in a structured population. These include biases cycles, dual circular flows, partial bipartite graphs and what we call ‘single-link’ graphs.

Coherent fans in the space of flows in framed graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
Let $G=(V,E)$ be a finite acyclic directed graph. Being motivated by a study of certain aspects of cluster algebras, we are interested in a class of triangulations of the cone of non-negative flows in $G, \mathcal F_+(G)$.

Acoustic hysteresis in flows with different kinds of relaxation and attenuation [PDF]

open access: yesArchives of Acoustics, 2022
Graphs in the thermodynamic plane acoustic pressure versus excess acoustic density representing acoustic hysteresis, are considered as indicators of relaxation processes, equilibrium parameters of a flow, and kinds of wave exciters.

Linear Algebraic Relations among Cardinalities of Sets of Matroid Functions

open access: yesMathematics, 2023
We introduce a unifying approach for invariants of finite matroids that count mappings to a finite set. The aim of this paper is to show that if the cardinalities of mappings with fixed values on a restricted set satisfy contraction–deletion rules, then ...
