Blood‐Based Circulating Tumor DNA Assays for Early Colorectal Cancer Detection: A Systematic Review of Performance in Asymptomatic Screening Populations

International Journal of Cancer, EarlyView.
Early detection of colorectal cancer via population‐based screening programs can reduce incidence and mortality, but current screening approaches are limited. This systematic review evaluated the screening potential of blood‐based circulating tumor DNA assays in asymptomatic screening populations.

Application of Machine Learning Techniques to Distinguish between Mare, Cryptomare, and Light Plains in Central Lunar South Pole−Aitken Basin

The Planetary Science Journal
We apply machine learning techniques to identify and map resurfacing units in the central South Pole−Aitken (SPA) basin using three Lunar Reconnaissance Orbiter (LRO) mission data sets: 321/415 nm and 566/689 nm band reflectance ratios from Hapke ...

AUTOMATED DETECTION OF LUNAR RIDGES BASED ON DEM DATA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Wrinkle ridges are a common feature in the lunar maria and record subsequent contraction of mare infill. Automatic detection of wrinkle ridges is challenging because the ridges are of irregular shapes and many ridges have been eroded and/or degraded over

Surface Temperature Variations during the Lunar Nighttime [PDF]

, 1964
A new photometer incorporating a mercury-doped germanium photoconductor has been used with a 19-inch telescope to measure the 8-14- brightness temperatures of the shaded lunar surface.

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 ...

Space Weathering Properties of Chang’e-6 Soils and Implication for Regolith Evolution of Young Lunar Maria

The Astrophysical Journal Letters
Lunar soil samples from young maria (formed 3.0 Ga) and higher than the ∼21% found in the Chang’e-5 soils from younger mare (∼2.0 Ga). However, our spectroscopic study reveals that the Chang’e-6 soils are well developed, with high maturity, weak ...

Lunar Outgassing, Transient Phenomena and The Return to The Moon, I: Existing Data

, 2007
Herein the transient lunar phenomena (TLP) report database is subjected to a discriminating statistical filter robust against sites of spurious reports, and produces a restricted sample that may be largely reliable.

The Scholar Imprisoned: Young‐Bok Shin's Decolonial Thought Against (Sub) Imperialisms in East Asia

Sociological Forum, EarlyView.
ABSTRACT This article reads Young‐Bok Shin (1941–2016) as a decolonial thinker who theorized transformative worldmaking from the standpoint of the oppressed, rooted in the historical experiences of East Asia. Against the (sub)imperial “logic of sameness” that structures colonial modernity in his social world, Shin advances gongbu (studying) as a ...

The search for the ultimate exercise countermeasure to preserve crew health and ensure mission success in long‐duration spaceflight

Experimental Physiology, EarlyView.
Abstract The current understanding of crew health maintenance is founded upon decades of physiological research conducted in terrestrial spaceflight analogues and in low Earth orbit, particularly on the International Space Station. However, as we progress towards the Lunar Gateway and interplanetary missions, it is imperative that the tools employed to
