Dynamic regulation of the transcriptome and proteome of the equine embryo during maternal recognition of pregnancy

FASEB BioAdvances, Volume 4, Issue 12, Page 775-797, December 2022., 2022
Abstract During initial maternal recognition of pregnancy (MRP), the equine embryo displays a series of unique events characterized by rapid blastocyst expansion, secretion of a diverse array of molecules, and transuterine migration to interact with the uterine surface.

Formation of a polar-ring galaxy in a galaxy merger [PDF]

, 1998
We numerically investigate stellar and gas dynamics in star-forming and dissipative galaxy mergers between two disk galaxies with specific orbital configurations. We find that violent relaxation combined with gaseous dissipation in galaxy merging transforms two disk galaxies into one S0 galaxy with polar-rings: Both the central S0-like host and the ...

MASS AND ENVIRONMENT AS DRIVERS OF GALAXY EVOLUTION IN SDSS AND zCOSMOS AND THE ORIGIN OF THE SCHECHTER FUNCTION [PDF]

, 2010
We explore the simple inter-relationships between mass, star formation rate, and environment in the SDSS, zCOSMOS, and other deep surveys. We take a purely empirical approach in identifying those features of galaxy evolution that are demanded by the data

Galaxy harassment and the evolution of clusters of galaxies [PDF]

Nature, 1996
Disturbed spiral galaxies with high rates of star formation pervaded clusters of galaxies just a few billion years ago, but nearby clusters exclude spirals in favor of ellipticals. ``Galaxy harassment" (frequent high speed galaxy encounters) drives the morphological transformation of galaxies in clusters, provides fuel for quasars in subluminous hosts ...

A Slowly Pulsating Run‐Away B Star at High Galactic Latitude Ejected From a Spiral Arm

Astronomische Nachrichten, EarlyView.
ABSTRACT We report the discovery of the young B6 V run‐away star LAMOST J083323.18 + 430825.4, 2.5 kpc above the Galactic plane. Its atmospheric parameters and chemical composition are determined from LAMOST spectra, indicating normal composition. Effective temperature (Teff$$ {T}_{\mathrm{eff}} $$ = 14,500$$ \mathrm{14,500} $$ K) and gravity (logg ...

Comparisons of the environmental dependence of galaxy properties between galaxies above and below M [PDF]

, 2009
From the Main galaxy sample of the Sloan Digital Sky Survey Data Release 6 (SDSS DR6), we construct two volume-limited samples above and below the value of M, to explore the difference of the environmental dependence of galaxy properties between galaxies above and below the value of M .

RECONCILING DWARF GALAXIES WITH ΛCDM COSMOLOGY: SIMULATING A REALISTIC POPULATION OF SATELLITES AROUND A MILKY WAY–MASS GALAXY [PDF]

, 2016
Low-mass “dwarf” galaxies represent the most significant challenges to the cold dark matter (CDM) model of cosmological structure formation. Because these faint galaxies are (best) observed within the Local Group (LG) of the Milky Way (MW) and Andromeda (

Staphylococcus Aureus AgrA Modulators from South African Antimicrobial Plants.

Chemistry &Biodiversity, Accepted Article.
South African plants are an underutilized metabolites source for novel antimicrobials targeting key quorum sensing (QS) systems like the Staphylococcus aureus AgrA. AgrA modulating metabolites constitute a new approach to reducing resistance development.

Visualizing the Hidden Features of Galaxy Morphology with Machine Learning [PDF]

arXiv, 2018
We train three convolutional neural networks (CNNs) to classify galaxies with Galaxy Zoo 2 dataset and extract the activations from the last fully connected layer or the last average pooling layer of CNNs to study the high-dimensional abstract feature representations of galaxy images.
