Radar Characterization of Salt Layers in Europa's Ice Shell as a Window Into Critical Ice‐Ocean Exchange Processes

open access: yesGeophysical Research Letters
The potential habitability of Jupiter's moon Europa has motivated two missions: NASA's Europa Clipper and ESA's JUpiter ICy moons Explorer (JUICE). Both missions are equipped with ice‐penetrating radars which will transmit radio waves into the subsurface,

The Effects of Environmental Policy Stringency on Firms' Performances: Focusing on Korean Manufacturing Industry

open access: yesAsian-Pacific Economic Literature, EarlyView.
ABSTRACT This study analysed how stringent environmental policy affects firms' performances in Korean manufacturing. The environmental policy stringency index published by the OECD was used as the main explanatory variable. As for the firms' performances variables, real total cost, real total sales and real EBIT were used, which capture the impact ...

Science Objectives of the Ganymede Laser Altimeter (GALA) for the JUICE Mission [PDF]

open access: yesarXiv, 2018
Laser altimetry is a powerful tool for addressing the major objectives of planetary physics and geodesy, and have been applied in planetary explorations of the Moon, Mars, Mercury, and the asteroids Eros, and Itokawa. The JUpiter Icy Moons Explorer (JUICE), led by European Space Agency (ESA), has started development to explore the emergence of ...

Advancements in radiocarbon dating: An overview of its impact on Mexican archaeology

open access: yesArchaeometry, EarlyView.
Abstract In this article, we provide a concise historical summary tracing the evolution of radiocarbon dating techniques in Mexico and Central America. We explore the contributions of early pioneers who first employed radiocarbon dating methods, leading to the establishment of a Mexican accelerator mass spectrometry laboratory. The study highlights its

Getting a grip: On causation, agency, and the meaning of “manipulation”

open access: yesTheoria, Volume 88, Issue 6, Page 1228-1247, December 2022., 2022
Abstract In the philosophy of causation, manipulationist literature is broadly divided into agency and interventionist accounts. The division between these accounts is partially due to a dispute regarding the meaning of “manipulation”, which specifically questions, “Must one analyse manipulation by appealing to human agency?” This paper attempts to ...

Near-infrared Spectroscopy for Remote Sensing of Porosity, Density, and Cubicity of Crystalline and Amorphous H2O Ices in Astrophysical Environments

open access: yesThe Astrophysical Journal
We present laboratory spectra of pure amorphous and crystalline H _2 O ices in the near-infrared (NIR, 1–2.5 μ m/10,000–4000 cm ^−1 ) at 80–180 K.

A look-back to the 50-year exploration of Jupiter's atmosphere

open access: yes地球与行星物理论评
Jupiter is the biggest and fastest-rotating planet in our solar system. As a gas giant without land–sea distribution or topography, Jupiter is an ideal natural laboratory for studying atmospheric dynamics.

Climate‐related drivers of migratory bird health in the south‐central USA

open access: yesBiological Reviews, EarlyView.
ABSTRACT Migratory birds are species of concern that play important ecological roles while also supporting recreational opportunities for the hunting and birdwatching public. Direct and indirect effects of climate variability, extremes, and change on migratory bird health manifest at the individual, population, species, and community levels.

Feasibility of Passive Sounding of Uranian Moons Using Uranian Kilometric Radiation

open access: yesEarth and Space Science
We present a feasibility study for passive sounding of Uranian icy moons using Uranian Kilometric Radio (UKR) emissions in the 100–900 kHz band. We provide a summary description of the observation geometry, the UKR characteristics, and estimate the ...
