Large-scale Structures in COSMOS2020: Evolution of Star Formation Activity in Different Environments at 0.4 < z < 4

The Astrophysical Journal
To study the role of environment in galaxy evolution, we reconstruct the underlying density field of galaxies based on COSMOS2020 (The Farmer catalog) and provide the density catalog for a magnitude-limited ( K _s < 24.5) sample of ∼210,000 galaxies at 0.

Is Less More? Field Evidence on the Impact of Anti‐Bribery Policies on Employee Knowledge and Corrupt Behavior

Regulation &Governance, EarlyView.
ABSTRACT Companies increasingly adopt internal norms to enhance compliance with legal rules. However, the rapid growth in volume and complexity of such internal rules may obstruct employee knowledge and understanding of such internal rules, and therefore also their compliance.

Environment and Gas Fraction in Type 2 AGN versus Non-AGN Galaxies

The Astrophysical Journal
We investigate the environmental parameters and gas fraction ( f _gas ) properties of type 2 active galactic nuclei (AGN) and non-AGN galaxies, utilizing a large sample of galaxies from the Sloan Digital Sky Survey DR7 with z ≤ 0.3.

Computers in Our Cosmos: Intersections in Geographies of Care, Abolition Geographies and Worker Movements

Transactions of the Institute of British Geographers, EarlyView.
ABSTRACT AI assistants on spacecrafts. Netflix streamed through inter‐planetary communication networks. Colonies on Mars by 2050. While the glamorous public–private ventures into outer space curate discussions on the technical specificities of these proposed projects, this paper reorients discussions on such developments through critical frameworks of ...

BST1047+1156: A (Failing) Ultradiffuse Tidal Dwarf in the Leo I Group

The Astrophysical Journal
We use deep Hubble Space Telescope imaging to study the resolved stellar populations in BST1047+1156, a gas-rich, ultradiffuse dwarf galaxy found in the intragroup environment of the Leo I galaxy group.

Low‐dose X‐ray radiation induces an adaptive response: A potential countermeasure to galactic cosmic radiation exposure

Experimental Physiology, EarlyView.
Abstract Space exploration involves many dangers including galactic cosmic radiation (GCR). This class of radiation includes high‐energy protons and heavy ionizing ions. NASA has defined GCR as a carcinogenic risk for long‐duration space missions. To date, no clear strategy has been developed to counter chronic GCR exposure.

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

Experimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

Experimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.
