Accessing Ultra‐Nano Phase‐Separated Metallic Glasses via Cryogenic Cycling
ABSTRACT Phase separation offers a promising avenue to mitigate the inherent brittleness of metallic glasses. However, traditional approaches relying on mixing enthalpy face significant challenges, primarily due to the detrimental impact on glass‐forming ability.

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review
ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to

Abstract Race and language collaborate in structuring educational inequities, creating urgency for teacher education to equip all teachers to equitably serve racialized multilinguals as antiracist language educators. Emphasizing the inseparability of racial and linguistic justice, this article examines teacher candidates' (TCs') learning journeys ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244 Cm sources, and come with severe concerns on radiation safety and isotope availability.

Tracking Deep Mantle Melting on Mars Using Phobos Tides
Abstract We study the deep internal structure and rheological state of Mars by analyzing its response to tidal forces exerted by Phobos and by introducing a melt fraction in the mantle layers. Motivated by recent seismic evidence for a basal molten layer near the base of the Martian mantle, we explore the distribution of melt within the mantle and its ...

Neural Network Imputation of the Pitch‐Angle‐Resolved Medium‐Energy Electron Flux Data in LEO
Abstract Pitch‐angle‐resolved electron flux data are crucial for investigating variations in electron flux within the magnetosphere and the underlying mechanisms, such as radial diffusion and wave‐particle interactions. The Medium‐Energy Electron Detector (MEED) onboard the Fengyun‐3E (FY‐3E) satellite in Low Earth Orbit (LEO) provides 18‐directional ...

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space
As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...

ABSTRACT The current trend of individualized food items (nutrient content and flavor) can be particularly valuable to support people's health and well‐being in isolated environments where access to fresh foods and diverse nutrition is difficult. At the same time, bioactive compounds and micronutrients can be employed to countermeasure any health ...

ABSTRACT Objective Soluble receptor for advanced glycation end‐products (sRAGE) and soluble Toll‐like receptor 4 (sTLR4) are circulating pattern recognition receptor isoforms implicated in inflammatory regulation in type 2 diabetes mellitus (T2DM). This study examined the effects of supervised aerobic exercise training (AET) on circulating sRAGE, sTLR4,
