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.

The formation of galaxy discs [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 Galaxy disk formation must incorporate the multiphase nature of the interstellar medium. The resulting two-phase structure is generated and maintained by gravitational instability and supernova energy input, which yield a source of turbulent viscosity that is able to effectively compete in the protodisk phase with early angular momentum loss of the ...

Triggering Star Formation by Galaxy-Galaxy Interactions [PDF]
Symposium - International Astronomical Union, 2004 We analyzed the effects of having a close companion on the star formation activity of galaxies in the 8K galaxy pair catalog selected from the 2dFGRS. We found that, statistically, galaxies with rp < 25h−1 kpc and ΔV < 100km s−1 have enhanced star formation with respect to isolated galaxies with the same luminosity and redshift distribution.

A LAW FOR STAR FORMATION IN GALAXIES [PDF]
The Astrophysical Journal, 2011 We study the galactic-scale triggering of star formation. We find that the largest mass-scale not stabilized by rotation, a well defined quantity in a rotating system and with clear dynamical meaning, strongly correlates with the star formation rate in a wide range of galaxies.

Formation of a Polar Ring Galaxy in a Galaxy Merger [PDF]
The Astrophysical Journal, 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 ...

Solvent‐Guided Chiral Assemblies and Chemical Doping of OEG‐Functionalized Conjugated Polymers
Advanced Materials, EarlyView.Solvent‐dependent aggregation pathways dictate whether conjugated polymers form chiral lyotropic liquid‐crystalline assemblies or achiral packed aggregates. Mapping solvent‐controlled β₁ and β2 states reveals that weaker backbone association favors β₁ aggregates and reorganizable twisted mesophases, whereas stronger backbone association favors β2 ...

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Proceedings of the International School of Physics “Enrico Fermi”, 1995 A review on numerical simulations of galaxy formation is given. Different numerical methods to solve collisionless and gas dynamical systems are outlined and one particular simulation technique, Smoothed Particle Hydrodynamics, is discussed in some detail. After a short discussion of the most relevant physical processes which affect the dynamics of the
