The Turán number of Berge matchings

Yichen Wang · Zixuan Yang · Xiamiao Zhao · Yuhang Bai · y 1 más

Given a graph $F$, an $r$-uniform hypergraph $\mathcal{H}$ is a {\em Berge-$F$} if there is a bijection $ϕ:E(F)\to E(\mathcal{H})$ such that $e\subseteq ϕ(e)$ for each $e\in E(F)$. Given a family $\mathcal{F}$ of $r$-uniform hypergraphs, an $r$-uniform hypergraph is $\mathcal{F}$-free if it does not contain any member...

Does the impact of calorie (energy) labelling on food purchased in worksite cafeterias differ by food category? A mega-analysis of field trials

Madison Luick · Natasha Clarke · Gareth J. Hollands · Susan A. Jebb · y 4 más

Calorie labels may help limit energy intake as part of policy efforts to prevent obesity. However, evidence on their effectiveness is mixed. We hypothesised this variability may relate to differences in responsiveness to labelling by food category, e.g., main meals vs. discretionary items (e.g. snacks). Systematic sear...

Diagonally-reduced tensor-product polynomials: Dimensions and boundary–diagonal matching

Domen Gradišek · Jan Grošelj

We study subspaces of tensor-product polynomials of bi-degree ▫$(n, n)$▫ on the unit square whose restrictions to the domain diagonals have degree reduced by an integer ▫$k \le n$▫. For maximal reduction ▫$k = n$▫, these diagonally-reduced spaces coincide with the Bézier-Smart surface spaces and have dimension ▫$n^2 +...

Speciation and Chemical Behavior of Mo in UO2 Samples Prepared by Hydroxide Coprecipitation

NICOLAS DACHEUX · Christoph HENNIG · Mohammad HUSAINY · Mathias FULCHIRON · y 1 más

Of all the fission products, molybdenum has a very special chemistry in irradiated uranium oxide fuels. The Mo presence is expected to influence the spent fuel dissolution during reprocessing. This impact may be more or less significant, depending on the speciation of the Mo element in the uranium dioxide. The aim of t...

Dimensional balance improves large scale spatiotemporal prediction performance

Jing Chen · Shixiang Pan · Yujie Fan · Haocheng Ye · y 2 más

Accurate spatiotemporal pattern analysis is critical in fields such as urban traffic, meteorology, and public health monitoring. However, existing methods face performance bottlenecks, typically yielding only incremental gains and often exhibiting limited cross-domain transferability. We analyze this bottleneck through...

Products of three conjugacy classes in the alternating group

Daniele Dona

We prove that for $δ$ small, $n$ large, and any three conjugacy classes $C_{1},C_{2},C_{3}$ of $G=\mathrm{Alt}(n)$ of size at least $|G|^{1-δ}$ we have $C_{1}C_{2}C_{3}=G$. The result provides a positive answer to Problem 20.23 of the Kourovka Notebook [KM22], improves theorems of Garonzi and Maróti [GM21] (using $4$ c...

Durability and Safety of PULSTA Transcatheter Pulmonary Valve: Insights From Five-Year Nationwide Post-Marketing Surveillance Study in Korea

Kyung-Jin Ahn · Gi Beom Kim · Sang Yun Lee · Seong Ho Kim · y 18 más

Data on the real-world performance of PULSTA™ transcatheter pulmonary valve implantation (TPVI) in patients with native right ventricular outflow tract (RVOT) dysfunction remain limited. We aim to evaluate the real-world safety and mid-term effectiveness of the self-expanding PULSTA™ transcatheter pulmonary valve in pa...
