Large monochromatic components and long monochromatic cycles in random hypergraphs [PDF]
European Journal of Combinatorics, 2019 We extend results of Gyárfás and Füredi on the largest monochromatic component in $r$-colored complete $k$-uniform hypergraphs to the setting of random hypergraphs. We also study long monochromatic loose cycles in $r$-colored random hypergraphs. In particular, we obtain a random analog of a result of Gyárfás, Sárközy, and Szemerédi on the longest ...

Monochromatic sums and products in $\mathbb{N}$ [PDF]
, 2016 An old question in Ramsey theory asks whether any finite coloring of the natural numbers admits a monochromatic pair $\{x+y,xy\}$. We answer this question affirmatively in a strong sense by exhibiting a large new class of non-linear patterns which can be

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions
Advanced Functional Materials, EarlyView.DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Discrete Mathematics, 1993 Let \(K_\omega\) denote the complete graph on the natural numbers. It is shown that if the edges of \(K_\omega\) are colored with 2 colors, then there is a monochromatic infinite path \(P\) with upper density \(\geq 2/3\), where the upper density for \(P\) is \(\limsup_{n\to\infty}|V(P)\cap\{1,2,\dots,n\}|/n\).

Effect of Spectral Quality of Monochromatic LED Lights on the Growth of Artichoke Seedlings
Frontiers in Plant Science, 2017 Indoor farming is becoming a popular alternative approach in food production to meet the demand of a growing world population. Under this production system, artificial light provides the main source of illumination in sustaining plant growth and ...

Advanced Functional Materials, Volume 36, Issue 43, 29 May 2026.A previously unreported coordination motif stabilising single Fe atoms by indigo chelation and pyridyl coordination on Au(111) has been revealed. By using planar tritopic pyridyl linkers (TPyB), extended 2D porous networks of indigo3(TPyB)2Fe6 form. These networks can be crystalline or vitreous and offer an environment where individual coordination ...

Advanced Functional Materials, EarlyView.In this strategy, a conductive nano‐probe is employed to induce nanoscale phase transitions and map the nanoscale conductivity and trap density of GST films. By utilizing the contrasting properties of phase‐change states, nano‐resonators are fabricated that exhibit plasmonic conduction and dramatically different transport characteristics.

γ-Cycles In Arc-Colored Digraphs
Discussiones Mathematicae Graph Theory, 2016 We call a digraph D an m-colored digraph if the arcs of D are colored with m colors. A directed path (or a directed cycle) is called monochromatic if all of its arcs are colored alike.
