Role of Dead‐End Regions and Transmitting Pores in Mixing and Reactivity in Unsaturated Porous Media

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Mixing‐limited reactions in unsaturated porous media are controlled by complex pore‐scale processes arising from air and water phases coexistence. Decreasing water saturation increases flow heterogeneity, creating preferential flow paths and dead‐end regions (DER) that alter solute distribution and reaction efficiency.

Projection-Free Methods for Online Distributed Quantized Optimization With Strongly Pseudoconvex Cost Functions

open access: yesIEEE Access
This paper investigates online distributed optimization within multi-agent systems under inequality constraints. Agents are allowed to exchange local data with their immediate neighbors through a time-varying digraph and perform computations, aiming to ...

Gradual pollen release in a buzz‐pollinated plant: Investigating pollen presentation theory under bee visitation

open access: yesFunctional Ecology, Volume 40, Issue 2, Page 476-485, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The rate at which flowers dispense pollen across successive pollinator visits is a key functional trait influencing male reproductive success. Pollen presentation theory (PPT) predicts that when pollinators are abundant and actively groom their bodies to collect pollen,

Uncertainty orders on the sublinear expectation space

open access: yesOpen Mathematics, 2016
In this paper, we introduce some definitions of uncertainty orders for random vectors in a sublinear expectation space. We all know that, under some continuity conditions, each sublinear expectation 𝔼 has a robust representation as the supremum of a ...

Variation in Tree Growth Increases With Global Warming

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
In recent decades, considerable research has focused on the long‐term trend of tree growth rates under global warming, yet little attention has been paid to trends in high‐frequency tree growth variations—that is, year‐to‐year differences in growth rates.

Nearly Hamilton cycles in sublinear expanders and applications

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract We develop novel methods for constructing nearly Hamilton cycles in sublinear expanders with good regularity properties, as well as new techniques for finding such expanders in general graphs. These methods are of independent interest due to their potential for various applications to embedding problems in sparse graphs.
