Hamiltonian approach to hybrid plasma models

The Hamiltonian structures of several hybrid kinetic-fluid models are identified explicitly, upon considering collisionless Vlasov dynamics for the hot particles interacting with a bulk fluid. After presenting different pressure-coupling schemes for an ord ...

Santiago de Chile and the Transantiago: How much technological progress is bearable?

Regina Witter

The paper intends to identify the requirements of technological progress in public transportation and resultant impacts on people’s daily life and social inequalities, with a specific regard to the case of Santiago de Chile. There public transport policy h ...

A Time-Domain Wavelet-Based Approach for Fluorescence Diffuse Optical Tomography

Michaël Unser, Chandra Sekhar Seelamantula

Purpose: In the context of fluorescence diffuse optical tomography, determining the optimal way to exploit the time-resolved information has been receiving much attention and different features of the time-resolved signals have been introduced. In this art ...

On Degraded Two Message Set Broadcast

Christina Fragouli, Suhas Diggavi, Vinod Malathidevi Prabhakaran, Shirin Saeedi Bidokhti

We consider the two message set problem, where a source broadcasts a common message

W_1

to an arbitrary set of receivers

\mathcal{U}

and a private message

W_2

to a subset of the receivers

\mathcal{P}\subseteq \mathcal{U}

. Transmissions occur over l ...

Clarifications to the limitations of the s-alpha equilibrium model for gyrokinetic computations of turbulence

Laurent Villard, Stephan Brunner, Sébastien Jolliet, Xavier Lapillonne, Alessandro Marinoni

In the context of gyrokinetic flux-tube simulations of microturbulence in magnetized toroidal plasmas, different treatments of the magnetic equilibrium are examined. Considering the Cyclone DIII-D base case parameter set [Dimits et al., Phys. Plasmas 7, 96 ...

Excited-State Dynamics of Hybrid Multichromophoric Systems: Toward an Excitation Wavelength Control of the Charge Separation Pathways

Natalie Renuka Banerji, Stefan Matile, Eric Vauthey

The photophysical properties of two hybrid multichromophoric systems consisting of an oligophenylethynyl (OPE) scaffold decorated by 10 red or blue naphthalene diimides (NDIs) have been investigated using femtosecond spectroscopy. Ultrafast charge separati ...

On Fidelity Per Unit Cost

Bixio Rimoldi, Marius Kleiner

We consider source coding with a ﬁdelity criterion, channel coding with a channel input constraint, and the combined problem of reproducing a source across a noisy channel. All three cases face a similar tradeoff between resource and performance, and the o ...

Fast Adaptive Elliptical Filtering Using Box Splines

Michaël Unser, Kunal Narayan Chaudhury

We demonstrate that it is possible to filter an image with an elliptic window of varying size, elongation and orientation with a fixed computational cost per pixel. Our method involves the application of a suitable global pre-integrator followed by a point ...
