\section{Introduction}
We consider in this paper the problem of multiplicative noise removal. To effectively restore images degraded by multiplicative noise, we develop a method which consists of an optimization model and an iterative algorithm to solve the minimization problem. Based on the nonlocal self-similarity of... | {

\section{Introduction}
The Minkowski space $\mathbb{R}^{n,1}$ is $\mathbb{R}^{n+1}$ with the metric
$$dx_1+\cdots +dx_n^2-dx_{n+1}^2.$$
A smooth function $u:\mathbb{R}^n\rightarrow\mathbb{R}$ is spacelike if $|Du(x)|<1$ for all $x\in\mathbb{R}^n.$ This alternatively means that its graph $M$ is a spacelike hypersurface ... | {

\subsection{Background}
One goal of geometric measure theory is to understand the global structure of a measure through analysis of local geometric data. We use the below terminology to formalize this notion.

Let $(\mathbb{X}, \mathcal{M})$ be a measurable space, and ... | {

The current outbreak of the new coronavirus in Mainland China (COVID-19,

\section{Introduction}
In this work, our goal is to \emph{automate} the design of efficient distributed and parallel algorithms for solving graph problems, as far as possible. In the full generality, such tasks are undecidable: for example, given a Turing machine $M$, we can easily construct a graph problem $\Pi$ such... | {

Here we give an algorithm for the BSD-DW problem.

In particular, it solves WECP thereby proving Theorem~\ref{thm:algo}.
We now give a description of the algorithm.

The world's financial system is a complex network where financial institutions such as banks are connected via various kinds of financial contracts. If some financial institutions go bankrupt, then others might suffer as well; the financial network might experience a ripple effect. Two of the ... | {
