Short-term solutions

Arctic temperatures are increasing because of long- and short-lived climate forcers, with reduction of the short-lived species potentially offering some quick mitigation. Now a regional assessment reveals the emission locations of these short-lived species ...

GREAT3 results - I. Systematic errors in shear estimation and the impact of real galaxy morphology

Frédéric Courbin, Jean-Luc Starck, Thibault Adrien Kuntzer, Malte Tewes, Huanyuan Shan, Marc Gentile, Guldariya Nurbaeva, Jun Zhang

We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravitational lensing shear distortions from simulated galaxy images. GREAT3 was ...

Achieving Marton's Region for Broadcast Channels Using Polar Codes

Rüdiger Urbanke, Seyed Hamed Hassani, Marco Mondelli

This paper presents polar coding schemes for the two-user discrete memoryless broadcast channel (DM-BC) which achieve Marton's region with both common and private messages. This is the best achievable rate region known to date, and it is tight for all clas ...

To Share or Not to Share: Adjustment Dynamics in Sharing Markets

Thomas Alois Weber, Maryam Razeghian Jahromi

To aid in the description and estimation of the tremendous recent growth in the collaborative economy, we provide a model for the dynamic sharing, subject to ﬁxed costs. The sharing economy comprises a set of inﬁnitely lived, heterogeneous suppliers, who t ...

Isogeometric Finite Elements With Surface Impedance Boundary Conditions

Annalisa Buffa, Rafael Vazquez Hernandez

First- and second-order surface impedance boundary conditions are introduced in the harmonic 2-D variational formulation based on the magnetic vector potential. The problem is discretized with isogeometric finite elements, a recent method that uses NURBS f ...

Nondispersive Decay For The Cubic Wave Equation

Roland Donninger

We consider the hyperboloidal initial value problem for the cubic focusing wave equation (-partial derivative(2)(t) + Delta(x))nu(t, x) + nu(t, x)(3) = 0, x is an element of R-3 Without symmetry assumptions, we prove the existence of a codimension-4 Lipsch ...

An Adaptive Multiscale Finite Element Method

Patrick Henning

This work is devoted to an adaptive multiscale finite element method (MsFEM) for solving elliptic problems with rapidly oscillating coefficients. Starting from a general version of the MsFEM with oversampling, we derive an a posteriori estimate for the H-1 ...
