An Exact Method for Reliable Shortest Path Problems With Correlation

Networks, Volume 87, Issue 4, Page 372-389, June 2026.
ABSTRACT Shortest path problems often arise in contexts where travel times are uncertain. In these settings, reliable paths are often valued more than paths with lower expected travel times. This has led to several variants of reliable shortest path problems (RSPP) that handle travel time reliability differently. We propose an algorithmic framework for

A Top‐Down View of Global and Regional Carbon Budgets From an Ensemble of Atmospheric Inversions

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Atmospheric inversions provide surface CO2 flux estimates based on in situ observed atmospheric CO2 mole fractions or satellite‐based column average CO2 (XCO2). Here, we provide a detailed assessment of 14 atmospheric CO2 inversions included in the Global Carbon Budget (GCB2024).

Asymptotics for the Spectrum of the Laplacian in Thin Bars with Varying Cross Sections

Mathematical Methods in the Applied Sciences, Volume 49, Issue 8, Page 8044-8060, 30 May 2026.
ABSTRACT We consider spectral problems for the Laplace operator in 3D rod structures with a small cross section of diameter O(ε)$$ O\left(\varepsilon \right) $$, ε$$ \varepsilon $$ being a positive parameter. The boundary conditions are Dirichlet (Neumann, respectively) on the bases of this structure, and Neumann on the lateral boundary.

Non-negative and positive solutions for some indefinite sublinear elliptic problems

Boundary Value Problems
We study the existence of non-negative and positive solutions to the indefinite sublinear elliptic problem − Δ u = λ u + m ( x ) | u | α − 1 u $\ -\Delta u=\lambda u+m(x)\left \vert u\right \vert ^{\alpha -1}u$ in Ω, u = 0 $u=0$ on ∂Ω, where Ω is a ...

Assessing the Role of Tropical Cyclones on Drought Characteristics in the Hurricane Region of the Americas Between 1983 and 2024

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Droughts and tropical cyclones (TCs) are among the deadliest and costliest natural hazards and are expected to intensify in the twenty‐first century due to anthropogenic climate change. The Hurricane Region of the Americas (HRA), an area frequently affected by TCs and droughts, is home to some of the most vulnerable countries to these hazards ...

Analysis of a Mathematical Model of Marital Satisfaction

Mathematical Methods in the Applied Sciences, Volume 49, Issue 7, Page 6143-6157, 15 May 2026.
ABSTRACT A large number of marriages end in divorce. In this paper, we present a model for the emotional state of a couple based on bilinear ordinary differential equations. We study the effect of changes of each individual's self‐emotional state on the couple's state.
