Terrestrial Lithium Exploration Adapted From Raman Diagnosis of Phyllosilicates for Mars

Journal of Raman Spectroscopy, EarlyView.
Analyses using a benchtop Raman instrument at the University of Aberdeen and a prototype instrument for remote deployment on Mars based at the University of Leicester successfully discriminated between four varieties of mica (possibly lithium‐rich rocks).

The habitability of super-Earths in Gliese 581

, 2007
Aims: The planetary system around the M star Gliese 581 consists of a hot Neptune (Gl 581b) and two super-Earths (Gl 581c and Gl 581d). The habitability of this system with respect to the super-Earths is investigated following a concept that studies the ...

The habitability of stagnant-lid Earths around dwarf stars [PDF]

, 2018
The habitability of a planet depends on various factors, such as delivery of water during the formation, the co-evolution of the interior and the atmosphere, as well as the stellar irradiation which changes in time.

Advances and Trends in Terrain Classification Methods for Off‐Road Perception

Journal of Field Robotics, EarlyView.
ABSTRACT Off‐road autonomous vehicles (OAVs) are becoming increasingly popular for navigating challenging environments in agriculture, military, and exploration applications. These vehicles face unique challenges, such as unpredictable terrain, dynamic obstacles, and varying environmental conditions.

Habitable Zone Lifetime of Exoplanets around Main Sequence Stars [PDF]

, 2013
Funding: Dean's Scholarship at the University of East Anglia.The potential habitability of newly discovered exoplanets is initially assessed by determining whether their orbits fall within the circumstellar habitable zone of their star.

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Habitable Zones in Extrasolar Planetary Systems [PDF]

, 2002
If we ask the question about the possible existence of the life outside the Earth, we first have to determine the habitable zone (HZ) for our solar system. The HZ of distances between a main sequence star and an Earth-like planet is roughly defined as the range of mean orbital radii which imply moderate planetary surface temperatures suitable for the ...

Biodiversity–food trade‐offs when agricultural land is spared from production

American Journal of Agricultural Economics, EarlyView.
Abstract Biodiversity conservation in agricultural landscapes, the world's predominant land use, could involve sparing, or setting aside, agricultural land from production, implying biodiversity–food trade‐offs. Employing bird species and agricultural data in two panel data sets, we evaluate the extent of set‐aside's trade‐offs in England between 1992 ...

Identification and characterization of a new ensemble of cometary organic molecules

Nature Communications, 2022
A new analysis of Rosetta mass spectra reveals an ensemble of complex organic molecules with striking similarities to other organic reservoirs in the Solar System, including Saturn’s ring rain material, pointing at a likely joint prestellar history.

M Dwarf Planet Habitability [PDF]

, 2017
The habitability of M dwarf planets has been debated greatly, as their parent stars possess both beneficial and detrimental qualities for the development of life.
