Red Galaxies Growing in Dark Matter Halos

, 2009
To understand the slow growth of massive galaxies at z < 1, we have modeled how these galaxies populate dark matter halos. The models are constrained with the observed luminosity function and clustering of z < 1 red galaxies.

Formation ofin situstellar haloes in Milky Way-mass galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2015
We study the formation of stellar haloes in three Milky Way-mass galaxies using cosmological smoothed particle hydrodynamics simulations, focusing on the subset of halo stars that form in situ, as opposed to those accreted from satellites. In situ stars in our simulations dominate the stellar halo out to 20 kpc and account for 30-40 per cent of its ...

Artificial intelligence‐driven bioinformatics: From analytical pipelines to model‐centered biological discovery

iMetaOmics, EarlyView.
AI‐driven bioinformatics is best viewed as an emerging model‐centered discovery framework in which learned representations increasingly support prediction, intervention design, and workflow orchestration, while classical pipelines remain essential for validation and reproducibility.

Stellar halos from deep VST surveys: comparing observations and theory [PDF]

, 2019
In the recent years, a big effort was made to develop deep photometric surveys aimed at studying galaxy structures down to the faintest levels of surface brightness of mu_g~27-30 mag/arcsec^2 .

The Dark, Gaseous, and Stellar Halos of Galaxies in LCDM as Tracers of Evolution [PDF]

, 2020
Within LCDM, galaxies are regulated by both large-scale processes such as mergers, tidal torques and smooth accretion via filaments, as well as by small-scale processes such as star formation and feedback. These mechanisms leave characteristic signatures

Liquid biopsy across cancers: Integrating circulating biomarkers, tumor biology, artificial intelligence, and clinical translation

Interdisciplinary Medicine, EarlyView.
Liquid biopsy uses non‐invasive sampling of blood or body fluids to isolate circulating analytes, including circulating tumor DNA, circulating tumor cells, extracellular vesicles, and RNA. These are analyzed using next‐generation sequencing, qPCR, and proteomics to inform cancer detection, monitoring, and characterization. Figure created with BioRender.

Probing the Dark Matter Halos of External Galaxies with Stellar Streams

The Astrophysical Journal
Stellar streams have proven to be powerful tools for measuring the Milky Way’s gravitational potential and hence its dark matter (DM) halo. In the coming years, the Vera Rubin Observatory, Euclid, ARRAKIHS, and the Nancy Grace Roman Space Telescope will ...

Sensorial and nutritional qualities of muscles from cross‐bred Salers heifers raised on mid‐mountain pasture

JSFA reports, EarlyView.
Abstract Background This study investigated the effects of crossbreeding, finishing system, and muscle type on carcass characteristics, intramuscular fat (IMF), image‐based IMF estimation, fatty acid composition, and meat quality in beef heifers. Charolais × Salers (C × S) and Angus × Salers (A × S) crossbred heifers were finished either on pasture or ...

Galaxy Groups in the SDSS DR4: III. the luminosity and stellar mass functions [PDF]

, 2009
Using a large galaxy group catalog constructed from the Sloan Digital Sky Survey Data Release 4 (SDSS DR4) with an adaptive halo-based group finder, we investigate the luminosity and stellar mass functions for different populations of galaxies (central ...

Understanding the Concept of Self‐Performed Ultrasound: A Scoping Review

Journal of Ultrasound in Medicine, EarlyView.
Self‐performed ultrasound is an emerging technology that facilitates adept self‐scans in untrained hands. Inspired by self‐performed imaging in space for more prompt diagnosis and therapy, it has the potential to accurately monitor chronic conditions remotely. However, the lack of supervision and physical restraints can hinder its usability.
