Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

Animal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.

The Heavy Metal Survey: Star Formation Constraints and Dynamical Masses of 21 Massive Quiescent Galaxies at z = 1.3–2.3

The Astrophysical Journal
In this paper, we present the Heavy Metal Survey, which obtained ultradeep medium-resolution spectra of 21 massive quiescent galaxies at 1.3 < z < 2.3 with Keck/LRIS and MOSFIRE.

A unified empirical model for infrared galaxy counts based on observed physical evolution of distant galaxies

, 2012
7 pages, 4 figures, 1 table, ApJL in pressInternational audienceWe reproduce the mid-infrared to radio galaxy counts with a new empirical model based on our current understanding of the evolution of main-sequence (MS) and starburst (SB) galaxies. We rely

Toll‐like receptor 4 mediates lipopolysaccharide‐induced emesis

British Journal of Pharmacology, EarlyView.
Background and Purpose Lipopolysaccharide (LPS) induces inflammation and sepsis through Toll‐like receptor 4 (TLR4) activation. Common laboratory animals do not exhibit emesis, but administration of LPS in piglets, cats, and dogs induces emesis via peripheral mechanisms.

UVCANDELS: The Role of Dust on the Stellar Mass–Size Relation of Disk Galaxies at 0.5 ≤ z ≤ 3.0

The Astrophysical Journal
We use the Ultraviolet Imaging of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey fields (UVCANDELS) to measure half-light radii in the rest-frame far-UV for ∼16,000 disk-like galaxies over 0.5 ≤ z ≤ 3. We compare these results to rest-

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

Computer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

The Effect of Galaxy Interactions on Starbursts in Milky Way-mass Galaxies in FIRE Simulations

The Astrophysical Journal
Simulations and observations suggest that galaxy interactions may enhance the star formation rate (SFR) in merging galaxies. One proposed mechanism is the torque exerted on the gas and stars in the larger galaxy by the smaller galaxy.
