Anti‐Astrotropik — Outer space, technology and resistance in the tropics

open access: yesSingapore Journal of Tropical Geography, Volume 47, Issue 2, Page 289-316, May 2026.
This paper traces an intellectual and geographical arc of thinking about outer space in the tropics, connecting Peter Redfield's Space in the Tropics: From Convicts to Rockets in French Guiana (2000), Sean T. Mitchell's Constellations of Inequality: Space, Race, and Utopia in Brazil (2017) and Asif Siddiqi's Cosmic Fragments: Dislocation and Discontent

Integrating contextual determinants and polygenic risk to examine dementia and late‐life cognition in the Multi‐Ethnic Study of Atherosclerosis

open access: yesAlzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Alzheimer's disease and related dementias are influenced by genetic and environmental risk factors. We investigated the relationship between contextual exposures and cognitive outcomes, independent of and in interaction with polygenic risk.

Estimation of gradients from sparse data by universal kriging [PDF]

open access: yesWater Resources Research, 2004
The determination of a gradient, or directional derivative, of a spatial variable is a common problem in many Earth science applications. For hydraulic heads, for example, the gradient defines the direction of the groundwater flow and is used in solving groundwater flow and transport equations.

A Hydrogeophysical Survey Utilising the sTEM and sTEMprofiler Systems: Transient Electromagnetic Data and Resistivity Models

open access: yesGeoscience Data Journal, Volume 13, Issue 2, April 2026.
We present a transient electromagnetic dataset from northwestern Denmark acquired with the novel sTEMprofiler system, mapping buried Quaternary valleys. The open dataset, including raw data and resistivity models, enables benchmarking of inversion methods and integration into geological and hydrological studies. ABSTRACT Transient electromagnetic (TEM)
