Feedback vertex set on chordal bipartite graphs [PDF]

open access: yes
Let G=(A,B,E) be a bipartite graph with color classes A and B. The graph G is chordal bipartite if G has no induced cycle of length more than four. Let G=(V,E) be a graph. A feedback vertex set F is a set of vertices F subset V such that G-F is a forest.

Entrepreneurial Market Leadership Claims, Cultural Resonance, and Investor Evaluations in Nascent Markets: The Goldilocks Effect

open access: yesJournal of Management Studies, EarlyView.
Abstract Cultural entrepreneurship research emphasizes entrepreneurs’ use of cultural resources to influence audience evaluations through resonance. However, the process by which such cultural resonance is achieved remains underexplored, particularly as an intermediary outcome.

Forbidden subgraphs of TI-power graphs of finite groups

open access: yesOpen Mathematics
Given a finite group GG with identity ee, the TI-power graph (trivial intersection power graph) defined on GG, denoted by Γ(G)\Gamma \left(G), is an undirected graph with vertex set GG where distinct vertices aa and bb are adjacent if ⟨a⟩∩⟨b⟩={e}\langle ...

Unique Perfect Phylogeny Characterizations via Uniquely Representable Chordal Graphs

open access: yes, 2013
The perfect phylogeny problem is a classic problem in computational biology, where we seek an unrooted phylogeny that is compatible with a set of qualitative characters.

Soybean Inositol Polyphosphate 5‐Phosphatase 8 Confers Salt Tolerance by Reducing Sodium Influx Through Inositol 1,4,5‐Trisphosphate Signalling

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Evidence suggests that the metabolism of inositol and its derivatives may be involved in various biological processes including salt tolerance, but there has been limited understanding. Ectopic expression of Gs5PTase8, an inositol polyphosphate 5‐phosphatase cloned from wild soybean (Glycine soja), significantly enhanced salt tolerance in ...

Component graphs of vector spaces and zero-divisor graphs of ordered sets

open access: yesAKCE International Journal of Graphs and Combinatorics
In this paper, nonzero component graphs and nonzero component union graphs of finite-dimensional vector spaces are studied using the zero-divisor graph of a specially constructed 0–1-distributive lattice and the zero-divisor graph of rings.

Finite groups whose coprime graph is split, threshold, chordal, or a cograph [PDF]

open access: yesProceedings of the Estonian Academy of Sciences
Given a finite group G, the coprime graph of G, denoted by Γ(G), is defined as an undirected graph with the vertex set G, and for distinct x, y ∈ G, x is adjacent to y if and only if (o(x), o(y)) = 1, where o(x) and o(y) are the orders of x and y ...

Leaf Length Predicts Twig Xylem Vessel Diameter Across Angiosperms

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT As plants grow taller, increasing conductive pathlength imposes hydraulic resistance, challenging the maintenance of water transport to leaves. While tip‐to‐base conduit widening along the stem helps mitigate this resistance, theoretical models and empirical data suggest that stem widening alone is insufficient to fully compensate.
