Hamiltonian paths in oriented graphs
Journal of Combinatorial Theory, Series B, 1976 AbstractA short proof is given of Meyniel's theorem on Hamiltonian cycles in oriented graphs. Analogous conditions are obtained for a graph to be Hamiltonianconnected.

Sinking peatlands: Optimal control of subsidence
American Journal of Agricultural Economics, EarlyView.Abstract Land subsidence threatens the living conditions of about 1.2 billion people worldwide in deltaic regions characterized by soft top soil. Economic activity in these areas requires lowering groundwater levels to keep the land sufficiently dry, which leaves future generations worse off by accelerating subsidence and increasing future costs.

British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Generalizability theory (G‐theory) defines a statistical framework for assessing measurement reliability by decomposing observed variance into meaningful components attributable to persons, facets, and error. Classic G‐theory assumes homoscedastic residual variances across measurement conditions, an assumption that is often violated in ...

The Legacy of Policy Inaction in Climate‐Growth Models
International Economic Review, EarlyView.ABSTRACT To better understand the structure and core mechanisms of a broad class of climate‐growth models, we study a simplified version of the dynamic integrated model of climate and the economy (DICE) through the lens of growth theory. We analytically show that this model features a continuum of saddle‐point stable steady states.

The Journal of Physiology, EarlyView.Abstract figure legend We present a shape modelling‐based morphological analysis of sex differences in cardiac anatomy. We conduct our analysis on 456 healthy subjects from the UK Biobank (227M/229F) to uncover sex‐based differences in healthy cardiac morphology.

Feynman path integrals for discrete-variable systems: Walks on Hamiltonian graphs
Physical Review ResearchWe propose a natural, parameter-free, discrete-variable formulation of Feynman path integrals. We show that for discrete-variable quantum systems, Feynman path integrals take the form of walks on the graph whose weighted adjacency matrix is the ...

Lifts of continuous and Hölder alpha curves in the configuration space MN/SN$M^N/S_N$
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract In this paper, we study the quotient space X=MN/SN$X = M^N / S_N$ of equivalence classes of N$N$‐tuples in a metric space (M,dM)$(M, d_M)$, equipped with the metric induced by the minimal total pairing distance. Given a continuous path F:(0,1)→X$F: (0,1) \rightarrow X$, we prove that there exist continuous functions f1,⋯,fN:(0,1)→M$f_1, \dots,

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1116-1133, 25 April 2026.ABSTRACT Recent tsunamigenic earthquakes in Japan have highlighted the emerging fire hazard triggered by tsunami inundation and its impact on tsunami vertical evacuation (TVE) structures. This new type of fire following earthquake, referred to as “tsunami fires,” may be a potential universal hazard that tsunami‐prone countries face; however, it has not
