DESCQA: An Automated Validation Framework for Synthetic Sky Catalogs [PDF]

, 2017
The use of high-quality simulated sky catalogs is essential for the success of cosmological surveys. The catalogs have diverse applications, such as investigating signatures of fundamental physics in cosmological observables, understanding the effect of ...

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

FEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

A catalog to unite them all: REGALADE, a revised galaxy compilation for the advanced detector era

Astronomy & Astrophysics
Context. Many applications in transient science, gravitational wave follow-up, and galaxy population studies require all-sky galaxy catalogs with reliable distances, extents, and stellar masses.

Semantic Union Catalogs: The Construction of Union Catalogs Based on BIBFRAME 2.0

Zhishi guanli luntan, 2016
[Purpose/significance] With the continuous improvement of bibliographic description models such as BIBFRAME, bibliographic data are facing the transition from MARC to the semantic bibliography. This paper explores the construction model of semantic union

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Gaia white dwarfs with infrared excess

Astronomy & Astrophysics
Context. The presence of infrared (IR) excess flux observed in white dwarfs is related to the existence of debris disks or substellar companions. These systems provide important clues in studies of extrasolar planetary material and binary evolution ...

Evolution of Western Library Catalogs: The Rising Expectations of Users

International Journal of Librarianship, 2018
This paper traces the historical development of library catalogs from primitive catalogs in ancient times to current next generational catalogs, which are summarized into three stages: the agricultural catalog stage, the industrial catalog stage and the ...

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

FEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Deep Bayesian spectral learning for the discovery of hot subdwarf binaries in LAMOST

Astronomy & Astrophysics
Context. Hot subdwarf binaries provide stringent constraints on envelope stripping and binary mass transfer. However, robust identification of these systems in large spectroscopic surveys is hindered by variable data quality and the subtle signatures of ...
