A novel characterization of cubic Hamiltonian graphs via the associated quartic graphs [PDF]
, 2017 We give a necessary and sufficient condition for a cubic graph to be Hamiltonian by analyzing Eulerian tours in certain spanning subgraphs of the quartic graph associated with the cubic graph by 1-factor contraction. This correspondence is most useful in

Scaling turbulence drives the general circulation
Quarterly Journal of the Royal Meteorological Society, EarlyView.The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

Sufficient conditions for a graph to be Hamiltonian [PDF]
, 1974 Three sufficient conditions for a graph to be Hamiltonian are given. These theorems are in terms of subgraph structure and do not require the fairly high global line density which is basic to the Pósa-like sufficiency conditions.

IET Collaborative Intelligent Manufacturing, Volume 8, Issue 1, January/December 2026.This paper proposes a dual‐strategy collaborative reinforcement learning path planning method in response to current technical limitations and engineering requirements in concrete 3D printing path planning. A dual‐DQN model was constructed based on the dual strategy collaborative mechanism.

GLONET: Mercator's End‐to‐End Neural Global Ocean Forecasting System
Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.Abstract Accurate ocean forecasting is crucial in different areas ranging from science to decision making. Recent advancements in data‐driven models have shown significant promise, particularly in weather forecasting community, but yet no data‐driven approaches have matched the accuracy and the scalability of traditional global ocean forecasting ...

Note on Hamiltonicity of Basis Graphs of Even Delta‐Matroids
Journal of Graph Theory, Volume 109, Issue 4, Page 446-453, August 2025.ABSTRACT We show that the basis graph of an even delta‐matroid is Hamiltonian if it has more than two vertices. More strongly, we prove that for two distinct edges e and f sharing a common end, it has a Hamiltonian cycle using e and avoiding f unless it has at most two vertices or it is a cycle of length at most four.

Energy Science &Engineering, Volume 13, Issue 6, Page 3185-3203, June 2025.The different reflux hole areas. ABSTRACT To investigate the impact of the reflux hole area on the self‐priming performance of a self‐priming pump, this study innovatively established a circulating pipeline system that includes the self‐priming pump, water tank, and other components.

On the wave turbulence theory of 2D gravity waves, I: Deterministic energy estimates
Communications on Pure and Applied Mathematics, Volume 78, Issue 2, Page 211-322, February 2025.Abstract Our goal in this paper is to initiate the rigorous investigation of wave turbulence and derivation of wave kinetic equations (WKEs) for water waves models. This problem has received intense attention in recent years in the context of semilinear models, such as Schrödinger equations or multidimensional KdV‐type equations. However, our situation
