, 2021 An early Paleozoic Proto-Tethys ocean in western Yunnan has long been postulated although no robust geological evidence has been identified. Here we investigated the recently-identified Mayidui and Wanhe ophiolitic melanges in SW Yunnan, which occurs in ...

Proto-oncogene Src links lipogenesis via lipin-1 to breast cancer malignancy
Nature Communications, 2020 Increased lipogenesis has been linked to an increased cancer risk and poor prognosis; however, the underlying mechanisms remain obscure. Here we show that phosphatidic acid phosphatase (PAP) lipin-1, which generates diglyceride precursors necessary for ...

Central Asian moisture modulated by proto-Paratethys Sea incursions since the early Eocene
Earth and Planetary Science Letters, 2019 The establishment and evolution of the Asian monsoons and arid interior have been linked to uplift of the Tibetan Plateau, retreat of the inland proto-Paratethys Sea and global cooling during the Cenozoic.

A systematic study of proto-neutron star convection in three-dimensional core-collapse supernova simulations [PDF]
Monthly notices of the Royal Astronomical Society, 2019 This paper presents the first systematic study of proto-neutron star (PNS) convection in three dimensions (3D) based on our latest numerical fornax models of core-collapse supernova (CCSN).

Geochimica et Cosmochimica Acta, 2019 The origin of sedimentary dolomite is a subject of long-standing enigma that still awaits resolution. Previous studies have shown that room temperature synthesis of abiotic dolomite is rarely achieved and primary (proto-)dolomite precipitation is closely

Condensation of Rubisco into a proto-pyrenoid in higher plant chloroplasts
Nature Communications, 2020 Photosynthetic CO2 fixation in plants is limited by the inefficiency of the CO2-assimilating enzyme Rubisco. In most eukaryotic algae, Rubisco aggregates within a microcompartment known as the pyrenoid, in association with a CO2-concentrating mechanism ...

A Tutorial Introduction to Quantum Circuit Programming in Dependently Typed Proto-Quipper [PDF]
International Workshop on Reversible Computation, 2020 We introduce dependently typed Proto-Quipper, or Proto-Quipper-D for short, an experimental quantum circuit programming language with linear dependent types.

Iron isotope evidence for very rapid accretion and differentiation of the proto-Earth
Science Advances, 2019 The iron isotope composition of Earth’s mantle requires planetary growth within 5 Ma of solar system formation. Nucleosynthetic isotope variability among solar system objects provides insights into the accretion history of terrestrial planets.

Ab Antiquo: Neural Proto-language Reconstruction [PDF]
North American Chapter of the Association for Computational Linguistics, 2019 Historical linguists have identified regularities in the process of historic sound change. The comparative method utilizes those regularities to reconstruct proto-words based on observed forms in daughter languages.
