Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented view of solar system bodies themselves, and of the structure and chemistry of forming ...

Safety of selective IL‐23p19 inhibitors for the treatment of psoriasis

Journal of the European Academy of Dermatology and Venereology, Volume 33, Issue 9, Page 1676-1684, September 2019., 2019
Abstract Psoriasis is a chronic disease that requires long‐term treatment. Consequently, understanding the safety and tolerability of any potential treatment over time is critical to effective prescribing. The biologic agents currently available for the treatment of psoriasis target a number of different inflammatory cytokines involved in psoriasis ...

Hydrodynamic Modeling of the Interaction of Winds within a Collapsing Turbulent Gas Cloud

Advances in Astronomy, Volume 2015, Issue 1, 2015., 2015
By using the particle‐based code Gadget2, we follow the evolution of a gas giant molecular cloud, in which a set of gas particles representing the wind are created by a Monte Carlo scheme and suddenly move outwards from the cloud’s center. The particles representing the gas cloud initially have a velocity according to a turbulent spectrum built in a ...

Fitting density models to observational data - The local Schmidt law in molecular clouds [PDF]

, 2013
We consider the general problem of fitting a parametric density model to discrete observations, taken to follow a non-homogeneous Poisson point process.

Physicochemical Constraints on the Abiotic Polymerization of Nucleotides Into RNA

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 11, November 2025.
Abstract One of the key steps in the origin of life is the polymerization of nucleotides into nucleic acids like RNA. We have quantified the energetic impact of temperature, pressure, and composition on the polymerization of nucleotides into RNA using the Gibbs function. These Gibbs energies have been used to calculate the probability that a nucleotide

A Hydrodynamical Model of a Rotating Wind Source and Its Effects on the Collapse of a Rotating Core

Advances in Astronomy, Volume 2015, Issue 1, 2015., 2015
This work presents three‐dimensional hydrodynamical simulations with the fully parallel GAGDET2 code, to model a rotating source that emits wind in order to study the subsequent dynamics of the wind in three independent scenarios. In the first scenario we consider several models of the wind source, which is characterized by a rotation velocity Vrot and

Physical structure of the envelopes of intermediate-mass protostars

, 2010
Context: Intermediate mass protostars provide a bridge between low- and high-mass protostars. Furthermore, they are an important component of the UV interstellar radiation field.

Rotational Spectroscopy of the Acetone‐Water Complex: Large Amplitude Motions

ChemPhysChem, Volume 25, Issue 21, November 4, 2024.
The structure and dynamics of the acetone‐water complex were explored using jet‐cooled rotational spectroscopy and computational chemistry calculations. Our detailed rot‐tunneling analyses of acetone‐H2O and −D2O revealed that the interaction with water disrupts the equivalence of the two methyl rotors, resulting in a significantly lower methyl rotor ...
