\section{Introduction} The estimation of the impact flux of near-Earth objects (NEOs) is important not only for the protection of human civilization, but also for the protection of space assets, which could be damaged or at least perturbed even by small, mm- to cm-size impactors. A recent example that reveals this nec...

\section{Introduction} The nearly simultaneous detection of gravitational waves GW170817 and the $\gamma$-ray burst GRB 170817A~\cite{TheLIGOScientific:2017qsa,% Monitor:2017mdv,GBM:2017lvd} places a very tight constraint on the speed of gravitational waves, $c_{\rm GW}$. The deviation of $c_{\rm GW}$ from the speed o...

\section{Introduction} The low-energy behavior of the non--Abelian gauge field theories is an open problem of quantum field theory. At low energies the effective interactions become strong and break down the usual perturbation theory, which works very well in the high-energy limit. This means that the vacuum at lo...

\section{Introduction} An open topic in machine learning is the transferability of a trained model to a new set of prediction categories without retraining efforts, in particular when some classes have very few samples. Few-shot learning algorithms have been proposed to address this, where prediction and training are...

\section{Introduction} Many real world optimization problems are formulated as $$\underset{x \in \Omega}{\text{min} }f(x)$$ where $f:\mathbb{R}^n \rightarrow \mathbb{R}$ is a nonlinear function, and $\Omega=\{x\in \mathbb{R}^n:l_i \leq x_i \leq u_i, \; i=1,\ldots,n\}$. In many cases, the gradient information required t...

\section{Introduction} Gravitational instantons are usually defined as complete nonsingular solutions of the vacuum Einstein field equations in Euclidean space \cite{h}, \cite{gh}, \cite{yau}-\cite{hit}. Among other things, they play an important role in the path-integral formulation of quantum gravity \cite{h1}, \cit...

\section{Introduction} The recent progress in heavy-ion spectroscopy provides good perspectives for testing the quantum electrodynamics in a region of strong electric field. In \cite{Marrs,Stohlker} the two-electron contribution to the ground-state energy of some heliumlike ions was measured directly by comparing the i...

\section{Introduction}\label{sec:Intro} Effective field theory (EFT) is a powerful tool for studying the dynamics of dense, strongly coupled matter, where a microscopic description is intractable. In this approach, one writes down an effective action principle for the degrees of freedom that remain at low energies and...

\section{The Linear Algebra Set-Up}\label{linalgsec} We will work over a field $\mathbb K$ of characteristic $0$. Given $m\geq0$, $n\geq 1$, $d\geq1$, there exists a natural sheaf homomorphism $$\Pi(n,d,m):\mathcal J^m(d)\longrightarrow\ocal_{\proj^n}(d)$$ where $\mathcal{J}^m(d)$ is the $m$th jet bundle of $\ocal...

Then, we use it to construct a nonlinear Youla parameterization for the uncertain linear system. Extensions to more ...

\section{Introduction} The inner AU around a pre-main sequence star is a complex region. Dust and gas flow inward through the disk, possibly accompanied by massive planets built in the outer disk \citep[e.g.][]{lin96}. Close to the star the dust will sublimate, creating an inner wall at a few tenths of an AU \citep{kam...

An individual flow field is too complicated to extract any simple and useful information from, and does not exhibit any universal laws. The mean flow fields, on t...
