Strong Jumps and Lagrangians of Non-Uniform Hypergraphs [PDF]

open access: yes, 2014
The hypergraph jump problem and the study of Lagrangians of uniform hypergraphs are two classical areas of study in the extremal graph theory. In this paper, we refine the concept of jumps to strong jumps and consider the analogous problems over non ...

Packed for Ossification: High‐Density Bioprinting of hPDC Spheroids in HAMA Toward Endochondral Ossification

open access: yesAdvanced Healthcare Materials, EarlyView.
Human periosteum‐derived cell spheroids bioprinted at high density within a hyaluronic acid matrix promote fusion and hypertrophic cartilage formation in vitro. Early encapsulation enhances spheroid interaction and matrix maturation, generating scalable cartilage templates intended for endochondral bone regeneration.

A Data Driven Review of In Vitro Electrical and Mechanical Stimulation for Post‐Acute Phase Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
This review examines how in vitro electrical and mechanical stimulation modulates wound healing in fibroblasts and keratinocytes. Analyzing over 560 experimental data points, we relate stimulation parameters to proliferation and migration outcomes, evaluate platform designs, and highlight the need for multi‐parameter optimization to advance targeted ...

Finitely forcible graphons with an almost arbitrary structure

open access: yesDiscrete Analysis, 2020
Finitely forcible graphons with an almost arbitrary structure, Discrete Analysis 2020:9, 36 pp. A basic result from the theory of quasirandom graphs, due to Andrew Thomason, is that if $G$ is a graph with $n$ vertices and density $p$, and if the number ...

Maximum Cycle Packing in Eulerian Graphs Using Local Traces

open access: yesDiscussiones Mathematicae Graph Theory, 2015
For a graph G = (V,E) and a vertex v ∈ V , let T(v) be a local trace at v, i.e. T(v) is an Eulerian subgraph of G such that every walk W(v), with start vertex v can be extended to an Eulerian tour in T(v).

Hypergraph removal lemmas via robust sharp threshold theorems

open access: yesDiscrete Analysis, 2020
Hypergraph removal lemmas via robust sharp threshold theorems, Discrete Analysis 2020:10, 46 pp. A central result in additive and extremal combinatorics is the triangle removal lemma, which roughly speaking states that a graph with few triangles can be ...
