\section{Introduction} Cauchy problem in several space dimension for hyperbolic system of conservation laws is a very important but complicated open problem. A particular kind of Cauchy problem in two-dimensional case is the two-dimensional Riemann problem which consists of initial data that are constant along any ray ...

\section{Introduction} Nearly all low-mass stars exhibit magnetic activity and some kind of mass outflow. Young stars add to this already complex situation by also undergoing {\em accretion} along a subset of the magnetic field lines that connect the star and its surrounding disk. Out of the many unanswered questions ...

Detecting and identifying abusive behavior can contribute to a more harmonious virtual environment. Given the huge amount of social media text produced every day,...

\section{Introduction} Deep Convolutional Neural Networks (CNNs) have achieved great results and become one of the leading methods for sophisticated tasks, such as computer vision and natural language processing, in recent years \citep{krizhevsky2012imagenet,simonyan2014very}. However, they are also very computational...

\section{Introduction} The study of weak coherent pion production in charged current (CC) and neutral current (NC) processes, is in the agenda of several current and future experiments~\cite{Hasegawa:2005td,Mahn:2006ac,Drakoulakos:2004gn,Ayres:2004js}. For instance, the SciBooNE detector~\cite{Mahn:2006ac} should b...

\section{Introduction} \label{sec:introduction} Dark matter haloes strongly affect the evolution of galactic bars: dynamical friction transfers angular momentum and energy from the galactic bar to the dark matter halo, allowing bars to slow and grow. This angular momentum transfer depends both on the density and on th...

\section{Introduction} The entries in the CKM matrix governing flavor transitions among quarks are fundamental parameters of the standard model (SM). As such they warrant intense experimental scrutiny. Currently the first two rows of the CKM are already being probed directly with ever improving precision using decays ...

\section{Introduction} Over the years, research in control of nonlinear dynamical systems has lead to many different tools to design (globally) asymptotically stabilizing feedbacks, see e.g. \cite{FreemanKokotovic:2008,Khalil:1992,Kokotovic:1992}. Usually these techniques require to impose special structure on the c...

\section{Introduction} \label{sec:intro} Markov Chain Monte Carlo (MCMC) methods are often used to generate samples from an unnormalized probability density $\pi(\theta)$ that is easy to evaluate but hard to directly sample. Such densities arise quite often in Bayesian inference as the posterior of a generative model $...

\section{Introduction} Weight systems and chord diagrams are central objects in the study of finite-type invariants, and Chern-Simons theory, in different contexts. Universal Vassiliev-type invariants typically take values in a space of diagrams -- e.g.~Jacobi, chord, etc. -- and weight systems are used to recover sp...
