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.

Fundamentals of Galaxy Dynamics, Formation and Evolution [PDF]

, 2019
Galaxies, along with their underlying dark matter halos, constitute the building blocks of structure in the Universe. Of all fundamental forces, gravity is the dominant one that drives the evolution of structures from small density seeds at early times ...

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.

Early assembly of the most massive galaxies [PDF]

, 2009
The current consensus is that galaxies begin as small density fluctuations in the early Universe and grow by in situ star formation and hierarchical merging(1).

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 ...
