Discrete Mathematics, 1976 AbstractIt is shown that every maximal planar graph (triangulation) can be contracted at an arbitrary point (by identifying it with an adjacent point) so that triangularity is preserved. This is used as a lemma to prove that every triangulation can be (a) oriented so that with three exceptions every point has indegree three, the exceptions having ...

Advanced Healthcare Materials, EarlyView.This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Orientable Burning Number of Graphs
Discrete Applied MathematicsIn this paper, we introduce the problem of finding an orientation of a given undirected graph that maximizes the burning number of the resulting directed graph. We show that the problem is polynomial-time solvable on Kőnig-Egerváry graphs (and thus on bipartite graphs) and that an almost optimal solution can be computed in polynomial time for perfect ...

Arbitrary Orientations of Hamilton Cycles in Oriented Graphs [PDF]
The Electronic Journal of Combinatorics, 2011 We use a randomised embedding method to prove that for all $\alpha>0$ any sufficiently large oriented graph $G$ with minimum in-degree and out-degree $\delta^+(G),\delta^-(G)\geq (3/8+\alpha)|G|$ contains every possible orientation of a Hamilton cycle. This confirms a conjecture of Häggkvist and Thomason.

Advanced Healthcare Materials, EarlyView.We introduce a new fabrication method that overcomes the current limitation of tubular gap electrospinning. We successfully fabricated a seamless hollow tube with fibers aligned along the longitudinal axis in diameters as small as 300 µm, and then reinforced it using 4‐axis 3D printing.

Caterpillars Have Antimagic Orientations
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018 An antimagic labeling of a directed graph D with m arcs is a bijection from the set of arcs of D to {1, …, m} such that all oriented vertex sums of vertices in D are pairwise distinct, where the oriented vertex sum of a vertex u is the sum of labels of ...
