Hölder Regularity of the Solutions of Fredholm Integral Equations on Upper Ahlfors Regular Sets

Mathematical Methods in the Applied Sciences, Volume 49, Issue 12, Page 13361-13381, August 2026.
ABSTRACT We extend to the context of metric measured spaces, with a measure that satisfies upper Ahlfors growth conditions, the validity of (generalized) Hölder continuity results for the solution of a Fredholm integral equation of the second kind. Here we note that upper Ahlfors growth conditions include also cases of nondoubling measures.

Lectotypifications and taxonomic changes in the holoparasitic Orobanchaceae

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
Based on further extensive studies of specimens in various herbaria, lectotypes are designated for many taxa of holoparasitic Orobanchaceae. In particular, 47 names in the genera Boschniakia (incl. Xylanche), Cistanche, Orobanche, Phelipanche and Phelypaea are lectotypified.

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.

Constraints on the hadronic light-by-light tensor in corner kinematics for the muon g − 2

Journal of High Energy Physics
The dispersive approach to the hadronic light-by-light contribution to the muon g − 2 involves an integral over three virtual photon momenta appearing in the light-by-light tensor.

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.

The Bocharova–Bronnikov–Melnikov–Bekenstein black hole’s exact quasibound states and Hawking radiation

European Physical Journal C: Particles and Fields
In this letter, we investigate behaviour of massive and massless scalar field that is represented by the covariant Klein–Gordon equation with Bocharova–Bronnikov–Melnikov–Bekenstein (BBMB) black hole background.

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 ...

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
