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 ...

Disk Galaxy Models Driven by Stochastic Self-Propagating Star Formation
Open Astronomy, 2010 We present a model of chemical and spectrophotometric evolution of disk galaxies based on a stochastic self-propagating star formation scenario. The model incorporates galaxy formation through the process of accretion, chemical and photometric evolution ...

Galaxy formation and evolution: low-surface-brightness galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We investigate in detail the hypothesis that low surface brightness galaxies (LSB) differ from ordinary galaxies simply because they form in halos with large spin parameters. We compute star formation rates using the Schmidt law, assuming the same gas infall dependence on surface density as used in models of the Milky Way.

Galaxy Formation and Evolution [PDF]
, 2005 We take a multi-faceted approach to study galaxy populations in the local universe, using the completed Two Degree Field Galaxy Redshift Survey (2dFGRS), the ``Millennium Run'' LCDM N-body simulation, and a semi-analytic model of galaxy formation. Our investigation covers both small and large scale aspects of the galaxy distribution.

Chemodynamical Modelling of Galaxy Formation and Evolution [PDF]
Astrophysics and Space Science, 2002 We present our recently developed 3-dimensional chemodynamical code for galaxy evolution. This code follows the evolution of different galactic components like stars, dark matter and different components of the interstellar medium (ISM), i.e. a diffuse gaseous phase and the molecular clouds.

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.

The Gaia-ESO survey: Open clusters as tracers of galactic chemical evolution
Astronomy & AstrophysicsAims. We investigate the formation and evolutionary trajectory of the Milky Way’s inner and outer galactic regions using stars from open clusters in the Gaia-ESO OC survey. Methods. Using numerical simulations from Chempy, we leveraged Markov chain Monte
