On the Hölder regularity for the fractional Schrödinger equation and its improvement for radial data

We consider the linear, time-independent fractional Schrödinger equation. We are interested in the local Hölder exponents of distributional solutions ψ, assuming local L p integrability of the functions V and f. By standard arguments, we obtain the formula ...

AWAKE, The Advanced Proton Driven Plasma Wakefield Acceleration Experiment at CERN

Yiming Li, Hua Zhang, Gennady Plyushchev, Shuai Liu

The Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) aims at studying plasma wakefield generation and electron acceleration driven by proton bunches. It is a proof-of-principle R&D experiment at CERN and the world's first proton driv ...

Energy dissipation in web-flange junctions of pultruded GFRP decks

Thomas Keller, Julia De Castro San Roman Fest, Sonia Yanes Armas

The energy dissipation capacity resulting from progressive cracking of the web-flange junctions (WFJs) of a pultruded GFRP deck system was experimentally investigated. Web-cantilever bending experiments up to failure were performed on two WFJ types (IfO, I ...

Discrete variational Lie group formulation of geometrically exact beams dynamics

Yves Weinand, Tudor Ratiu, François Gay-Balmaz, François Marie Alain Demoures

The goal of this paper is to derive a structure preserving integrator for geometrically exact beam dynamics, by using a Lie group variational integrator. Both spatial and temporal discretization are implemented in a geometry preserving manner. The resultin ...

Design and exploration of externally post-tensioned structures using graphic statics

Corentin Jean Dominique Fivet

Funicular structures, which follow the shapes of hanging chains, work in pure tension (cables) or pure compression (arches), and offer a materially efficient solution compared to structures that work through bending action. However, the set of geometries t ...

Numerical modeling of fluid–structure interaction in arteries with anisotropic polyconvex hyperelastic and anisotropic viscoelastic material models at finite strains

Alfio Quarteroni, Simone Deparis, Davide Forti

The accurate prediction of transmural stresses in arterial walls requires on the one hand robust and efficient numerical schemes for the solution of boundary value problems including fluid–structure interactions and on the other hand the use of a material ...

Similarity-Based Shape Priors for 2D Spline Snakes

Michaël Unser, Daniel Andreas Schmitter

We present a new formulation of a shape space containing all continuously defined 2D spline curves up to a similarity transform of a reference shape. We are able to measure a distance between an arbitrary curve and the shape space itself. Our contribution ...

No correlations between the magnitude of visual illusions

Michael Herzog, Lukasz Grzeczkowski, Aaron Michael Clarke, Fred Mast

In cognition, audition and somatosensation, performance correlates strongly between different tasks suggesting the existence of common factors. Surprisingly, this does not hold true for vision. For example, Vernier acuity and Gabor detection correlate very ...

Using electrical resistance networks to enhance performance assessments of water distribution networks

Ian Smith, Gaudenz Moser, Stephanie Ann German

Pressurized fluid-distribution networks are strategic elements of civil infrastructure. In the case of fresh-water distribution networks, where leaks are common and where real performance is unknown, advanced sensor-based diagnostic methodologies have the ...
