On the origin and evolution of life in the Galaxy [PDF]
International Journal of Astrobiology, 2010 AbstractA simple stochastic model for evolution, based upon the need to pass a sequence ofncritical steps is applied to both terrestrial and extraterrestrial origins of life. In the former case, the time at which humans have emerged during the habitable period of Earth suggests a value ofn=4.

Targeted decrease of portal hepatic pressure gradient improves ascites control after TIPS
Hepatology, EarlyView., 2022 The river diagram demonstrates that after transjugular intrahepatic portosystemic shunt insertion (TIPS) the majority of patients without ascites and 50% of the patients with ascites detectable at ultrasound, show the best response in the long term follow‐up.

High-redshift Dusty Star-Forming Galaxies: a panchromatic approach to constrain massive galaxy evolution [PDF]
, 2021 The goal of this thesis is to investigate the early stages of massive galaxy evolution by defining an overall view of their physical properties combining the information extracted by all the details of their spectral behaviour.

Janus kinase 2 inhibition by pacritinib as potential therapeutic target for liver fibrosis
Hepatology, EarlyView., 2022 Diagram of the activation of the profibrotic and procontractile Janus kinase 2 (JAK2)/Ras homolog family member A/Rho‐kinase pathway and the inhibition of phosphorylated JAK2 by pacritinib to inhibit hepatic stellate cell activity. Abstract Background and Aims Janus kinase 2 (JAK2) signaling is increased in human and experimental liver fibrosis with ...

Fractional yields inferred from halo and thick disk stars [PDF]
Serbian Astronomical Journal, 2013 Linear [Q/H]-[O/H] relations, Q = Na, Mg, Si, Ca, Ti, Cr, Fe, Ni, are inferred from a sample (N = 67) of recently studied FGK-type dwarf stars in the solar neighbourhood including different populations (Nissen and Schuster 2010, Ramirez et al ...

Tertiary mirror location diversity on very large etendue telescope architectures [PDF]
EPJ Web of ConferencesTwo distinct reflective telescope designs utilizing a variation of three-mirror anastigmat configuration were investigated. We demonstrate how the strategic placement of the tertiary mirror significantly influences the telescope's form factor, enabling ...

Formation of a Massive Lenticular Galaxy Under the Tidal Interaction with a Group of Dwarf Galaxies
The Astrophysical Journal Letters, 2023 Based on the atomic-hydrogen (H i ) observations using the Five-hundred-meter Aperture Spherical radio Telescope, we present a detailed study of the gas-rich massive S0 galaxy NGC 1023 in a nearby galaxy group.

The Evolution of Galaxy Groups and of Galaxies Therein [PDF]
, 2007 Properties of groups of galaxies depend sensitively on the algorithm for group selection, and even the most recent catalogs of groups built from redshift-space selection should suffer from projections and infalling galaxies. The cosmo-dynamical evolution of groups from initial Hubble expansion to collapse and virialization leads to a fundamental track (
