High‐Throughput Kinetics Enable Predicting Reactivity Across Mechanisms of Acid/Base Catalysis in Water

open access: yesAngewandte Chemie Novit, Volume 2, Issue 3, September 2026.
Quantitative predictions of reactivity in water remain challenging due to the multiparameter nature arising from acid‐base catalysis. We have established a high‐throughput kinetic workflow used to measure 6889 rate constants of a model carbonyl addition reaction.

Spatially Heterogeneous and Nonlinear Responses of Ecosystem Service Value to Human Activity Intensity in an Arid Mountain–Oasis–Desert Urban Agglomeration

open access: yesLand Degradation &Development, Volume 37, Issue 15, Page 11277-11297, September 2026.
ABSTRACT Rapid urbanization and agricultural expansion are reshaping human–environment relationships in arid regions; however, the spatially heterogeneous and nonlinear relationships between human activities and ecosystem services remain insufficiently understood.

A Generalized Framework for Data‐Efficient and Extrapolative Materials Discovery for Gas Separation

open access: yesAdvanced Intelligent Discovery, Volume 2, Issue 4, August 2026.
This study introduces an iterative supervised machine learning framework for metal‐organic framework (MOF) discovery. The approach identifies over 97% of the best performing candidates while using less than 10% of available data. It generalizes across diverse MOF databases and gas separation scenarios.

Geostatistical Modelling and Web‐Based Mapping of Malaria Risks Among Children Under Five Years in Nigeria: Evidence From the 2021 Nigeria Malaria Indicator Survey

open access: yesHealth Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background Malaria is a critical public health concern in Nigeria with the country bearing an uneven burden of the disease. In Nigeria, malaria is one of the main causes of child mortality and despite all efforts to reduce malaria mortality rates, the disease remains a major concern, notably among children under‐fives.

Detecting When One Probe Vector is Enough for Preconditioned Log‐Determinant Approximation

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 4, August 2026.
ABSTRACT We present randomized algorithms for estimating the log‐determinant of regularized symmetric positive semi‐definite matrices. The algorithms access the matrix only through matrix vector products, and are based on the introduction of a preconditioner and stochastic trace estimator.

Investigating the Utility of Fractal Measures as a Diagnostic for Glaucoma

open access: yesStatistics in Medicine, Volume 45, Issue 18-19, August 2026.
ABSTRACT Recent advances in Adaptive‐Optics Confocal Scanning Laser Ophthalmoscopy (AO‐cSLO) have enabled non‐invasive, in‐vivo imaging of retinal cell subsets, at near single‐cell resolution. However, challenges such as spatial and temporal variability, limited observation windows, and segmentation errors hinder the effective use of this data for ...

Hypertension at 5 months postpartum in women with gestational diabetes

open access: yesUltrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 202-210, August 2026.
ABSTRACT Objective Gestational diabetes mellitus (GDM) is associated with future maternal cardiovascular disease, independent of the development of Type‐2 diabetes mellitus. As a major cardiovascular risk factor, we examined the incidence and predictors of hypertension at 5 months postpartum in women with previous GDM.

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.
