Long‐Range Transport Pathways of Intense Wildfire Plumes in the Northern Hemisphere Observed by the IASI/METOP Satellite Mission

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Wildfires emit significant greenhouse gases and pollutants. Extreme fires disperse smoke plumes over long distances, necessitating a deeper understanding of their source regions and variability. This study introduces a plume back‐trajectory algorithm using carbon monoxide (CO) and peroxyacetyl nitrate satellite observations from the Infrared ...

Generalized Jensen and Jensen–Mercer inequalities for strongly convex functions with applications

open access: yesJournal of Inequalities and Applications
Strongly convex functions as a subclass of convex functions, still equipped with stronger properties, are employed through several generalizations and improvements of the Jensen inequality and the Jensen–Mercer inequality.

On inequalities of Jensen-Ostrowski type [PDF]

open access: yes, 2015
We provide new inequalities of Jensen-Ostrowski type, by considering bounds for the magnitude of (Formula Presented), with various assumptions on the absolutely continuous function f:[a,b]→C and a μ-measurable function g, and a complex number λ ...

Regularization via f‐Divergence: An Application to Multi‐Oxide Spectroscopic Analysis

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract In this paper, we explore the application of convolutional neural networks (CNNs) for predicting the chemical composition of complex geologic samples in a simulated Martian atmospheric environment. Specifically, we aim to characterize oxide weight percentages (wt.%) of rock samples analyzed by remote Laser‐Induced Breakdown Spectroscopy (LIBS),

Evolution of Senescence by Damage Accumulation That Accelerates With Age Throughout an Organism's Lifespan

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Senescence evolution is usually explained by reduced selection on late acting genes. Here we develop a new model for senescence evolution that complements the classic theory by focusing on genes that affect mortality throughout lifespan. Our work sheds light on the dynamics of senescence evolution and helps to reconcile phenomena that presented ...

Two Measures of Dependence

open access: yes, 2019
Two families of dependence measures between random variables are introduced. They are based on the R\'enyi divergence of order $\alpha$ and the relative $\alpha$-entropy, respectively, and both dependence measures reduce to Shannon's mutual information ...

Making geography move: The Royal Geographical Society and the exchange of periodical knowledge, 1830–1900

open access: yesArea, Volume 58, Issue 1, March 2026.
Short Abstract This paper examines how the Royal Geographical Society's (RGS's) Library and Map Committee disciplined the exchange of the first English‐language geographical journal in the nineteenth century. The periodical's archive reveals the institutional mechanisms that shaped the journal's networks of gifting and exchange but also the deliberate ...

Discontinuities in the Maximum-Entropy Inference

open access: yes, 2013
We revisit the maximum-entropy inference of the state of a finite-level quantum system under linear constraints. The constraints are specified by the expected values of a set of fixed observables.

Reconsidering climatic predictors for high‐resolution niche models of alpine plants

open access: yesOikos, Volume 2026, Issue 2, February 2026.
The increasingly acknowledged and consequently also better understood microclimatic variability in terrestrial ecosystems has motivated a call for finer spatial resolution in species distribution modelling, especially in the case of sedentary low‐stature organisms such as plants.

The causative role of amyloidosis in the cardiac complications of Alzheimer's disease: a comprehensive systematic review

open access: yesThe Journal of Physiology, Volume 604, Issue 4, Page 1646-1681, 15 February 2026.
Abstract figure legend Schematic illustration of the bidirectional causative link between cerebral amyloid‐beta (Aβ) angiopathy and cardiovascular disease in Alzheimer's disease (AD). Common cardiovascular risk factors like microvascular thrombosis, diabetes, atrial fibrillation, hypertension and atherosclerosis lead to cerebral hypoperfusion and ...
