Expanding the application of the Eu-oxybarometer to the lherzolitic shergottites and nakhlites: Implications for the oxidation state heterogeneity of the Martian interior [PDF]

, 2009
Experimentally rehomogenized melt inclusions from the nakhlite Miller Range 03346 (MIL 03346) and the lherzolitic shergottite Allan Hills 77005 (ALH 77005) have been analyzed for their rare earth element (REE) concentrations in order to characterize the ...

Constructing citizenship and indigeneity in Jordan: The politics of Bedouin rights and identities in cultural heritage sites

The Geographical Journal, EarlyView.
Short Abstract This paper explores the relationships between Bedouin rights, citizenship and indigeneity in cultural heritage sites in Jordan. Through interviews and ethnographic fieldwork with Bedouin communities, we argue that a more critical engagement with indigeneity is necessary in Jordan.

A spatially continuous magnetization model for Mars [PDF]

, 2005
[1] Using a three-component magnetic field data set at over 100,000 satellite points previously compiled for spherical harmonic analysis, we have produced a continuously varying magnetization model for Mars.

Comparison of Two Methods for Determination of Rhenium and Platinum‐Group Elements in Meteorites Using On‐Line and Off‐Line Matrix Separation Modes

Geostandards and Geoanalytical Research, EarlyView.
Key Points PEEK tubing has been observed to adsorb Pd and Pt ions, resulting in significantly reduced recoveries of Pd and Pt elements. HPA‐S provides a more effective dissolution for meteorite samples than Carius tube digestion, resulting in higher mass fractions for PGE.

Semantic Segmentation of Martian Landforms with Sparse Scribble Annotations Using a Pseudo-Labeling Strategy [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Deep learning-based semantic segmentation techniques play a crucial role in the rapid mapping of Martian landforms. However, creating an annotated dataset for Martian landforms is a labor-intensive and time-consuming process.

Constraints on Martian Chronology from Meteorites

Geosciences, 2020
Martian meteorites provide the only direct constraints on the timing of Martian accretion, core formation, magmatic differentiation, and ongoing volcanism. While many radiogenic isotope chronometers have been applied to a wide variety of Martian samples,

Temporal analysis of all high-resolution Mars imaging products [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
A meta-data analysis has been performed of high-resolution imagery that have been acquired over the last four decades from Mars. More specifically, we are interested in two independent image parameters, the time that each image was acquired and the ...

The JLS at 50: Art, literature and socio‐legal studies

Journal of Law and Society, EarlyView.
Abstract This article began life as a lecture the author was invited to deliver as part of the Journal's 50th‐anniversary celebrations in the summer of 2024. The piece explores how law, literature and socio‐legal studies in the United Kingdom have evolved alongside each other since the birth of the Journal of Law and Society in 1974.

Observations of Locally Generated Whistler-mode Waves in the Martian Magnetotail Current Sheet

The Astrophysical Journal, 2023
The whistler-mode wave is an electromagnetic wave that commonly occurs in space plasma and has been extensively studied, especially within the Earth's magnetosphere. They have also been reported in the near-Mars space, such as Martian upstream solar wind,
