The Economics of Testing for Biotech Grain: Application to StarLink Corn [PDF]

StarLink corn, a biotech variety not approved for human food use, disrupted the marketing system in 2000 because of inadvertent commingling. Testing protocols have since been established for detection of StarLink in corn shipments to Japan. Domestic food

Anti‐Astrotropik — Outer Space, Technology and Resistance in the Tropics

Singapore Journal of Tropical Geography, EarlyView.
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

Automated reduction of submillimetre single-dish heterodyne data from the James Clerk Maxwell Telescope using ORAC-DR [PDF]

, 2015
With the advent of modern multi-detector heterodyne instruments that can result in observations generating thousands of spectra per minute it is no longer feasible to reduce these data as individual spectra.

A High‐Efficiency Multivariable TEC‐SOFTS Model for Ionospheric TEC Prediction: Validation Over China Area During Low and High Solar Activity Periods

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The ionospheric Total Electron Content (TEC) is a key parameter for characterizing the ionospheric properties. In this study, an efficient multivariable time series prediction model, TEC‐Series Core Fusion and efficient multivariable time series (TEC‐SOFTS), was constructed by combining multiple geomagnetic and solar activity indices ...

Simulated Impact on LSST Data of Starlink V1.5 and V2 Satellites

The Astronomical Journal
The new Starlink V2 satellites incorporate improvements to the chassis brightness through dielectric mirrors, off-pointing solar arrays, and blackened exposed components. For the general case in which the reflectivities are initially unknown, we simulate

Comprehensive and Open Assessment of Thermospheric Models During Geomagnetic Storm Times Within CCMC Framework

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Thermospheric neutral density controls satellite drag in low Earth orbit and varies strongly during geomagnetic storms. We present a multi‐mission, phase‐resolved assessment of empirical and physics‐based thermosphere models using 151 storms from 2001 to 2023, including MSIS, DTM, JB2008, WAM‐IPE, WACCM‐X, GITM, CTIPe, and TIE‐GCM.
