Democratizing Hydroclimate Science for Just and Resilient Futures

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Hydroclimatic extremes are intensifying, escalating risks to ecosystems, infrastructure, and vulnerable communities. Rapid technological innovation and scientific discovery offer powerful tools to address these challenges, yet a gap remains between hydroclimate knowledge production and its use in decision‐making.

Solitary Waves of Moderate Amplitude and Dispersive Radiation in the Serre Equations: The Extended KdV–Whitham Approximation

Studies in Applied Mathematics, Volume 157, Issue 2, August 2026.
ABSTRACT We consider the extended Korteweg–de Vries (eKdV) equation as a model for long moderately nonlinear surface water waves and use it to describe the evolution of initial conditions generating solitary waves with and without significant dispersive radiation, as well as cases of pure dispersive radiation without any solitary waves.

Refined Modeling of Arctic Circumpolar Building Stock Increases Estimated Mid‐Century Permafrost Degradation Damages

Earth's Future, Volume 14, Issue 7, July 2026.
Abstract Near‐surface permafrost degradation has the potential to damage infrastructure needed to sustain Arctic communities, but risk assessments remain highly uncertain due to a limited representation of the Arctic circumpolar building stock. With deep learning building footprint detection and building occupancy classification models, we expand the ...

The Political Economy of Attention: Media Salience, Voter Cognition, and Electoral Accountability

Journal of Economic Surveys, Volume 40, Issue 3, Page 1173-1193, July 2026.
ABSTRACT We review conceptual and empirical contributions to the political economy of attention, with a focus on how attention allocation shapes political behavior and electoral accountability. The review distinguishes between endogenous (goal‐directed) and exogenous (stimulus‐driven) attention and examines how these concepts are incorporated into ...

Melnikov method for perturbed completely integrable systems

Bulletin of the Belgian Mathematical Society - Simon Stevin
We consider a completely integrable system of differential equations in arbitrary dimensions whose phase space contains an open set foliated by periodic orbits. This research analyzes the persistence and stability of the periodic orbits under a nonlinear periodic perturbation. For this purpose, we use the Melnikov method and Floquet theory to establish

Imminent Localized Precipitation Preceded by a Surge in Cloud‐Base Descent and Reflectivity

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The nowcasting of localized precipitation (LP) is often limited by insufficient observation of the vertical cloud evolution preceding rainfall. Here we systematically tracked rapid cloud development within 2 hr before LP onset, utilizing cloud data collected in 2024 from the millimeter‐wavelength cloud radar network across China, together with

Digital Roots or Digital Routes? Broadband Expansion and the Rural‐Urban Migration in China

Population and Development Review, Volume 52, Issue 2, Page 374-402, June 2026.
Abstract This study investigates how broadband internet affects rural–urban migration in China using the Universal Broadband and Telecommunication Services pilot program launched in 2015 as a quasi‐experimental setting. Analyzing China Household Finance Survey data (2013–2021) with difference‐in‐differences estimation, we find that improved internet ...

Open‐Source Tools for Building Data‐Driven, Sovereignty‐Permitting Web Apps

Journal of the Royal Society of New Zealand, Volume 56, Issue 2, April 2026.
Public domain or access‐controlled web apps provide a simple and relatively cheap way to increase the accessibility of information within data resources. Modern data environments, especially those subject to Māori Data Sovereignty (MDSov) constraints, face technical challenges balancing data security and privacy with accessibility and collective ...

Deciphering the “Missing Xenon Paradox” in Celestial Bodies: A Multifaceted Perspective Toward Demystifying This Enigma

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...
