Gravity inversion of deep-crust and mantle interfaces in the Three Gorges area
Geodesy and Geodynamics, 2012 To better understand the heterogeneity of deep-crust and mantle interfaces in the region of the Three Gorges, China, we used the Parker-Oldenburg iterative inversion method to invert existing Bouguer gravity data from the Three Gorges area (1 : 500000 ...

, 2014 A ground of the universe V is a transitive proper class W subset V, such that W is a model of ZFC and V is obtained by set forcing over W, so that V = W[G] for some W-generic filter G subset P in W . The model V satisfies the ground axiom GA if there are

Limnology and Oceanography Letters, EarlyView.Abstract The Japanese turban snail Lunella coreensis is sensitive to ocean currents due to its short pelagic larval stage and moderate dispersal ability, making it an ideal model for studying genetic diversity shaped by paleoclimatic shifts. In this study, we analyzed the mitochondrial genes COI and 12S of museum samples collected from various coasts ...

Evolution of Earth-like extrasolar planetary atmospheres: Assessing the atmospheres and biospheres of early Earth analog planets with a coupled atmosphere biogeochemical model [PDF]
published in Astrobiology, Volume 17, Issue 1, 2017, pp.27-54, 2018 Understanding the evolution of Earth and potentially habitable Earth-like worlds is essential to fathom our origin in the Universe. The search for Earth-like planets in the habitable zone and investigation of their atmospheres with climate and photochemical models is a central focus in exoplanetary science.

Rifting and arc-related early Paleozoic volcanism along the North Gondwana margin: geochemical and geological evidence from Sardinia (Italy) [PDF]
, 2012 Three series of volcanic rocks accumulated during the Cambrian to Silurian in the metasediment-dominated Variscan basement of Sardinia. They provide a record of the changing geodynamic setting of the North Gondwana margin between Upper Cambrian and ...

ChemSystemsChem, EarlyView.Self‐organisation may result from organic systems fed with free energy provided that reactivity becomes a determining factor. The propensity of carbon to form covalent bonds can give rise to kinetically stable thermodynamically activated compounds possibly undergoing non‐linear kinetic processes.

Research progress of Jiali fault activity
地球与行星物理论评, 2021 The Jiali fault is a large strike-slip fault that traverses the southeast of the Tibetan Plateau. It played an important role as an adjustment fault for adjusting stress balance both before and after the collision of the Indian and Eurasian plates. Based

Mercury's Internal Structure [PDF]
, 2018 We describe the current state of knowledge about Mercury's interior structure. We review the available observational constraints, including mass, size, density, gravity field, spin state, composition, and tidal response. These data enable the construction of models that represent the distribution of mass inside Mercury.

e1900035, 2019 The widespread presence of ribonucleic acid (RNA) catalysts and cofactors in Earth's biosphere today suggests that RNA was the first biopolymer to support Darwinian evolution. However, most "path-hypotheses" to generate building blocks for RNA require reduced nitrogen-containing compounds not made in useful amounts in the CO2-N2-H2O atmospheres of the ...
