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

, 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 ...

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

Advanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

Finitely forcible graphons with an almost arbitrary structure

Discrete 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 ...

Mechanoluminescent Aluminum Nitride Crystal for Super‐Sensitive Optical Manometry, Thermometry and Force Sensing

Advanced Materials, EarlyView.
This study reports the first discovery of intrinsic mechanoluminescence in undoped AlN crystals, accompanied by pronounced photoluminescence and persistent luminescence. It further demonstrates a defect‐emission–driven multifunctional optical sensing platform for force, pressure, and temperature detection, achieving exceptional sensitivities.

Maximum Cycle Packing in Eulerian Graphs Using Local Traces

Discussiones 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

Discrete 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 ...

Comparative Advances in Sulfide and Halide Electrolytes for Commercialization of All‐Solid‐State Lithium Batteries

Advanced Materials, EarlyView.
This review compares sulfide‐ and halide‐based solid electrolytes for all‐solid‐state lithium batteries (ASSBs), highlighting their ionic conductivity, chemical stability, manufacturability, and compatibility with lithium metal. Sulfides offer higher conductivity, while halides provide enhanced stability and scalability.

On a valence problem in extremal graph theory

Discrete Mathematics, 1973
Vorliegende Arbeit bezieht sich auf nicht-orientierte, Schlingen und mehrfache Kanten nicht enhaltende Graphen. Bezeichne \(L\) einen solchen vom vollständigen \(p\)-Graphen \(K_p\) verschiedenen \(p\)-chromatischen Graphen, welcher eine Kante \(e\) so enthält, daß \(L-e\) ein \((p-1)\)-chromatischer Graph ist. Als Hauptergebnis der vorliegenden Arbeit
