Quantification of Crystal Chemistry of Fe‐Mg Carbonates by Raman Microspectroscopy and Near‐Infrared Remote Sensing

open access: yesEarth and Space Science
On Earth, carbonate minerals are widely used as recorders of the geological environments in which they formed. Here, we present a method designed to retrieve the crystal chemistry of Fe‐Mg carbonate minerals using infrared remote sensing or Raman ...

Perspectives and Challenges in Bolide Infrasound Processing and Interpretation: A Focused Review with Case Studies

open access: yesRemote Sensing
Infrasound sensing plays a critical role in the detection and analysis of bolides, offering passive, cost-effective global monitoring capabilities. Key objectives include determining the timing, location, and yield of these events.

The Benefits of High Resolution Multispectral TIR Data and Its Impending Loss by NASA After Four Decades

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract NASA has led multispectral (≥3 wavelength bands) thermal infrared (TIR) sensor development from the earliest days of the agency. These data are critical in addressing a wide range of scientific questions and administration priories by measuring both temperature (for wildfire and volcanic eruption monitoring, agricultural plant stress, and ...

On the Dynamics of a Synchronous Binary Asteroid System with Non-Uniform Mass Distribution

open access: yesMathematics
In this work, particle dynamics in a binary asteroid system is analyzed within the Circular Restricted Three-Body Problem (CRTBP) framework, assuming the largest body is treated as a mass point.

Optimized SPE‐HPLC‐FLD Method for the Simultaneous Determination of Olaparib, Propranolol, and Furosemide in Human Urine

open access: yesBiomedical Chromatography, Volume 40, Issue 8, August 2026.
ABSTRACT Olaparib belongs to the PARP inhibitors and is widely used as an anticancer drug. Due to frequent side effects, it is usually co‐administered with an antihypertensive, such as propranolol and/or an antidiuretic, such as furosemide. In this study, a highly sensitive HPLC‐FLD method was developed for the simultaneous determination of the three ...

A Generalizable Tool for Predicting Developmental Phenology for Wild Ecotherms

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Custom hatch timing models developed for four North American Lithobates frog species. Models are parameterized from Moore (1939). Panels (A, B) shows differential developmental rates under varying thermal regimes and G × E interactions. ABSTRACT Development in poikilothermic organisms is strongly temperature‐dependent, particularly during early life ...

Supervised Machine Learning Approach to Iron Meteorite Classification Using Random Forest: A Predictive Model to Classify Ungrouped Irons

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Iron meteorites provide insight into the formation processes of planetary cores from the early Solar System. Through further classifying individual irons into specific groups, which are assumed to represent a common parent body, greater information can be yielded into the formation processes of those bodies.

Cultural geography of heat: Artistic experiments with heat’s animacies

open access: yesGeographical Research, Volume 64, Issue 3, August 2026.
A sustained, cultural geographical engagement with heat is long overdue. I advance this agenda by engaging with the work of contemporary artists. Artists are responding to uneven conditions of global heating by exploring heat’s animacies: how heat interweaves with the practices and textures of life.
