Bioactive Ingredients, Functions, and Development Strategies of Phascolosoma esculenta—An Edible Marine Organism: A Review

open access: yesFood Science &Nutrition, Volume 13, Issue 5, May 2025.
Phascolosoma esculenta is an invertebrate living in the ocean's intertidal zone, belonging to the phylum Sipuncula, and is often cooked as a delicious snack in China's coastal areas. It is often referred to as the “sea ginseng” because of its high nutritional value and the efficacy of enhancing endurance.

The Link Between Subsurface Rheology and Ejecta Mobility: The Case of Small New Impacts on Mars

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract The dynamics of crater ejecta are sensitive to the material properties of the target, much like the crater size and morphology. We isolate and quantify the effect of target properties on the ejecta mobility (EM) ‐ the maximum radial extent of ejecta scaled by the crater radius.

Evaluating 14C and 14C/10Be terrestrial age dating systems for meteorites using experimental data and model calculations

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 5, Page 1263-1283, May 2025.
Abstract This study presents a refined approach to determine 14C saturation activities and 14C/10Be saturation activity ratios in chondritic meteorites with the goal to improve terrestrial age dating. By combining new model calculations for 10Be, 14C, and cosmogenic (22Ne/21Ne)cos, along with experimental data from 17 freshly fallen chondrites, we ...

Extended star graphs [PDF]

open access: yes, 2016
Chordal graphs, which are intersection graph of subtrees of a tree, can be represented on trees. Some representation of a chordal graph often reduces the size of the data structure needed to store the graph, permitting the use of extremely efficient ...

Linking asteroids and meteorites to the primordial planetesimal population

open access: yesGeochimica et Cosmochimica Acta, 2020
Meteorites provide a unique insight into early Solar System processes. However, to fully interpret this record requires that these meteorites are related back to their source asteroids and ultimately to the original planetesimal population that formed ...

Linear-Time Algorithms for Maximum-Weight Induced Matchings and Minimum Chain Covers in Convex Bipartite Graphs

open access: yes, 2017
A bipartite graph $G=(U,V,E)$ is convex if the vertices in $V$ can be linearly ordered such that for each vertex $u\in U$, the neighbors of $u$ are consecutive in the ordering of $V$.

Structure and Reactivity of Terrestrial and Extraterrestrial Pyrrhotite [PDF]

open access: yes, 2012
Pyrrhotite (Fe1−xS) is a non-stoichiometric iron monosulfide common in terrestrial rocks, ore deposits, and many extraterrestrial materials. The non-stoichiometry due to metal vacancies relates to a variety of composition-dependent crystallographic ...
