Vector Field‐Based Collision‐Free Navigation in Tunnel‐Like Environments
Journal of Field Robotics, Volume 43, Issue 3, Page 2521-2547, May 2026.ABSTRACT Tunnel‐like environments, renowned for their vast scale, confined spaces, and limited visibility, present significant challenges for autonomous robot navigation. This study addresses the critical issue of guiding robots through such environments while ensuring collision‐free navigation and maintaining a specified safety margin from both tunnel

Sinking peatlands: Optimal control of subsidence
American Journal of Agricultural Economics, Volume 108, Issue 3, Page 926-953, May 2026.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.

Ambiguity Aversion, Portfolio Choice, and Life Expectancy
International Economic Review, Volume 67, Issue 2, Page 633-655, May 2026.ABSTRACT This paper studies how wealth and aging affect portfolio choices in a life‐cycle model with ambiguity aversion. Ambiguity aversion implies wealthier and older agents are endogenously more optimistic about risky asset returns, relative to poorer/younger agents. As life expectancy grows, old agents become even more optimistic, while young agents

Network Games With Triadic Interactions
International Economic Review, Volume 67, Issue 2, Page 605-632, May 2026.ABSTRACT We propose a model for network‐mediated interactions incorporating higher‐order relationships such as triadic interactions. The marginal utility of an individual's action depends explicitly on endogenous actions of multiple units. Conditions ensuring a unique Nash equilibrium are derived using a variational inequality approach. We estimate the

Structuro‐Functional Differentiation and Coupling of Gyri and Sulci in the Neonatal Cortex
Human Brain Mapping, Volume 47, Issue 6, April 15, 2026.The cortical gyro/sulcal regions are defined in each neonatal brain based on multi‐modal MRI images, and both structural and functional connectivity matrices among gyro‐sulcal regions are constructed and adopted to unveil the connectivity strength differences and coupling characteristics between gyri and sulci in neonatal brains.

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.ABSTRACT In this article, we propose a novel numerical framework for the non‐isothermal Cahn–Hilliard–Navier–Stokes two‐phase flow system, which couples the incompressible Navier–Stokes equations, the Cahn–Hilliard phase‐field equation, and the heat transport equation to capture temperature‐dependent two‐phase flow dynamics.

Electronic Journal of Differential Equations, 2017 In this article, we study the problem $$ -\operatorname{div}(K(x)\nabla u)=a(x)K(x)|u|^{q-2}u+b(x)K(x)|u|^{2^{\ast}-2}u, \quad x\in \mathbb{R}^N, $$ where $2^{\ast}=2N/(N-2)$, $N\geq3 ...
