Suppression of temperature-gradient-driven turbulence by sheared flows in fusion plasmas

Starting from the assumption that saturation of plasma turbulence driven by temperature-gradient instabilities in fusion plasmas is achieved by a local energy cascade between a long-wavelength outer scale, where energy is injected into the fluctuations, an ...

Adjoint-based variational methods for computing invariant solutions in spatio-temporally chaotic PDEs

Omid Ashtari

One approach for describing spatio-temporally chaotic dynamical systems, including fluid turbulence, is to study non-chaotic but unstable invariant solutions embedded within the chaotic attractor of the system. These include steady, periodic, and quasi-per ...

Self-exploring automated experiments for discovery, optimization, and control of unsteady vortex-dominated flow phenomena

Karen Ann J Mulleners

Typical unsteady vortex-dominated flows like those involved in bio-inspired propulsion, airfoil separation, bluff body wakes, and vortex-induced vibrations can be prohibitively expensive to simulate and impossible to measure comprehensively. These examples ...

Bi-Solitons on the Surface of a Deep Fluid: An Inverse Scattering Transform Perspective Based on Perturbation Theory

Andrey Gelash

We investigate theoretically and numerically the dynamics of long -living oscillating coherent structures -bi-solitons-in the exact and approximate models for waves on the free surface of deep water. We generate numerically the bi-solitons of the approxima ...

EFFECT OF LONGITUDINAL BEAM-COUPLING IMPEDANCE ON THE SCHOTTKY SPECTRUM OF BUNCHED BEAMS

Tatiana Pieloni

Schottky spectra can be strongly affected by collective effects, in particular those arising from beam-coupling impedance when a large number of bunch charges are involved. In such conditions, the direct interpretation of the measured spectra becomes diffi ...

Optimized Schwarz methods for the time-dependent Stokes-Darcy coupling

Tommaso Vanzan

This paper derives optimized coefficients for optimized Schwarz iterations for the time-dependent Stokes-Darcy problem using an innovative strategy to solve a nonstandard min-max problem. The coefficients take into account both physical and discretization ...

Search for the decay B-0 -> phi mu(+) mu(-)

Olivier Schneider, Aurelio Bay, Guido Haefeli, Tatsuya Nakada, Frédéric Blanc, Lesya Shchutska, Elena Graverini, Michel De Cian, Vladimir Macko, Sebastian Schulte, Donal Patrick Hill, Guillaume Max Pietrzyk, Maria Vieites Diaz, Marie Theres Christin Bachmayer, Lino Ferreira Lopes, Matthieu Philippe Luther Marinangeli, Serhii Cholak, Veronica Sølund Kirsebom, Ettore Zaffaroni, Surapat Ek-In, Ana Bárbara Rodrigues Cavalcante, Sara Celani, Renato Quagliani, Carina Trippl, Sonia Amina Bouchiba, Alison Maria Tully, Elisabeth Maria Niel, Maarten Willibrord Uriël Van Dijk

A search for the decay B-0 -> phi mu(+) mu(-) is performed using proton-proton collisions at centre-of-mass energies of 7, 8, and 13 TeV collected by the LHCb experiment and corresponding to an integrated luminosity of 9 fb(-1). No evidence for the B-0 -> ...

On the uniqueness of solutions for the basis pursuit in the continuum

Julien René Fageot, Thomas Jean Debarre

This paper studies the continuous-domain inverse problem of recovering Radon measures on the one-dimensional torus from low-frequency Fourier coefficients, where K (c) is the cutoff frequency. Our approach consists in minimizing the total-variation norm am ...

Controlled Growth of the Self-Modulation of a Relativistic Proton Bunch in Plasma

Ambrogio Fasoli, Ivo Furno, Patrick Blanchard, Yanis Andrebe, Riccardo Agnello, Christine Stollberg

A long, narrow, relativistic charged particle bunch propagating in plasma is subject to the self -modulation (SM) instability. We show that SM of a proton bunch can be seeded by the wakefields driven by a preceding electron bunch. SM timing reproducibility ...

Electric field control of antiferroelectric domain pattern

Alexander Tagantsev

Control of domain and domain wall configurations in antiferroelectrics is a necessary step towards practical use of new functionalities based on polar domain wall structures. Here we propose and demonstrate a domain engineering scheme that provides an anti ...
