A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, EarlyView.
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 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

Integration of Micro‐CT and XRF Mapping for Multimodal 3D Analysis of Polychrome Wooden Artifacts

X-Ray Spectrometry, EarlyView.
ABSTRACT Over the past 5 years, computer applications have become crucial to archeological research. Since the 1990s, the focus has transitioned from data management tools to the development of virtual models. Recently, digital documentation of cultural heritage has gained considerable focus, with 3D modeling of objects.

THE AESTHETICS OF URBAN METABOLISM: Landscape, Design and the Politics of In/Visibility

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article, we chart the evolving aesthetic contours of urban metabolism across London, focusing on the River Lea and Thamesmead to the north and south of the River Thames, respectively. We begin in the nineteenth century, when these two sites formed critical nodes within a new sewerage system that relegated the city’s circulatory flows ...

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

Integrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Low Sunscreen Awareness and Misconceptions in Skin of Colour With Acne‐Related Post‐Inflammatory Hyperpigmentation: A Cross‐Sectional Study Highlighting the Need for Targeted Education

Australasian Journal of Dermatology, EarlyView.
ABSTRACT Background/Objectives Post‐inflammatory hyperpigmentation (PIH) is a frequent sequela of acne in patients with skin of colour (SOC). While sunscreen is widely recommended for PIH prevention, little is known about real‐world sunscreen practices in this group. This study aimed to evaluate sunscreen use, barriers and factors influencing adherence
