Train wheel-rail force collaborative calibration based on GNN-LSTM
High-Speed RailwayAccurate wheel-rail force data serves as the cornerstone for analyzing the wheel-rail relationship. However, achieving continuous and precise measurement of this force remains a significant challenge in the field.

Flavour and Fragrance Journal, EarlyView.This framework transposes the perfumery olfactory pyramid to whisky maturation by sequencing aromas into top, heart, and base notes according to their temporal persistence. Using Log P as a behaviour‐based classification axis and oak macromolecules as natural fixative analogues, it proposes a behaviour‐based aromatic wheel bridging flavour chemistry ...

Saturated Partial Embeddings of Planar Graphs
Journal of Graph Theory, EarlyView.ABSTRACT In this work, we study how far one can deviate from optimal behavior when embedding a planar graph. For a planar graph G $G$, we say that a plane subgraph H ⊆ G $H\subseteq G$ is a plane‐saturated subgraph if adding any edge (possibly with new vertices) to H $H$ would either violate planarity or make the resulting graph no longer a subgraph of

The Minimal Nonplanar Strong Digraphs
Journal of Graph Theory, EarlyView.ABSTRACT Kuratowski's theorem says that the minimal (under subgraph containment) graphs that are not planar are the subdivisions of K 5 ${K}_{5}$ and of K 3 , 3 ${K}_{3,3}$. Here we study the minimal (under subdigraph containment) strongly‐connected digraphs that are not planar.

Journal of Plant Nutrition and Soil Science, EarlyView.We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

JSFA reports, Volume 5, Issue 3, Page 113-124, March 2025.Abstract Background Most pure maple syrup produced in North America is produced from the sap of sugar maple trees (Acer saccharum). Interest is growing to utilize other maple species in different regions of North America outside the native range of sugar maple.

Multi‐Agent Reinforcement Learning for Joint Police Patrol and Dispatch
Naval Research Logistics (NRL), EarlyView.ABSTRACT Police patrol units need to split their time between performing preventive patrol and being dispatched to serve emergency incidents. In the existing literature, patrol and dispatch decisions are often studied separately. We consider joint optimization of these two decisions to improve police operations efficiency and reduce response time to ...

On Ramsey numbers for trees versus fans of even order
Indonesian Journal of CombinatoricsGiven two graphs G and H. The graph Ramsey number R(G, H) is the least natural number r such that for every graph F on r vertices, either F contains a copy of G or F̅ contains a copy of H.
