An octree-based adaptive semi-Lagrangian free surface flow solver

A numerical method based on an adaptive octree space discretization for the simulation of 3D free-surface fluid flows is proposed. The Navier-Stokes equations are solved with a time-splitting scheme, which decouples advection from diffusion/incompressibili ...

Numerical modeling of heart valves using resistive Eulerian surfaces

Alfio Quarteroni, Aymen Laadhari

The goal of this work is the development and numerical implementation of a mathematical model describing the functioning of heart valves. To couple the pulsatile blood flow with a highly deformable thin structure (the valve's leaflets), a resistive Euleria ...

Surface fractal dimension, water adsorption efficiency, and cloud nucleation activity of insoluble aerosol

Athanasios Nenes

Surface porosity affects the ability of a substance to adsorb gases. The surface fractal dimension D is a measure that indicates the amount that a surface fills a space, and can thereby be used to characterize the surface porosity. Here we propose a new me ...

Technology mapping of reversible circuits to Clifford+T quantum circuits

Mathias Soeken, Nabila Abdessaied

The Clifford+T quantum gate library has attracted much interest in the design of quantum circuits, particularly since the contained operations can be implemented in a fault-tolerant manner. Since fault tolerant implementations of the T gate have very high ...

Creating femtosecond-laser-hyperdoped silicon with a homogeneous doping profile

Tobias Schneider

Femtosecond-laser hyperdoping of sulfur in silicon typically produces a concentration gradient that results in undesirable inhomogeneous material properties. Using a mathematical model of the doping process, we design a fabrication method consisting of a s ...

Free-Viewpoint Video Sequences: a New Challenge for Objective Quality Metrics

Touradj Ebrahimi, Philippe Hanhart

Free-viewpoint television is expected to create a more natural and interactive viewing experience by providing the ability to interactively change the viewpoint to enjoy a 3D scene. To render new virtual viewpoints, free-viewpoint systems rely on view synt ...

Real-time, high-speed video decompression using a frame- and event-based DAVIS sensor

Dynamic and active pixel vision sensors (DAVISs) are a new type of sensor that combine a frame-based intensity readout with an event-based temporal contrast readout. This paper demonstrates that these sensors inherently perform high-speed, video compressio ...

A quality assessment protocol for Free-viewpoint video sequences synthesized from decompressed depth data

Touradj Ebrahimi, Philippe Hanhart

In this paper, the analysis of a subjective quality experiment consisting in assessing the quality of free-viewpoint video sequences generated from decompressed depth data is presented. In the absence of a dedicated subjective assessment protocol for the e ...

Shock-induced deformation of Shergottites: Shock-pressures and perturbations of magmatic ages on Mars

Philippe Gillet, Pierre Beck

Shergottites and Chassignites practiced major deformation effects whose nature, magnitude and relevance were controversially evaluated and disputatively debated. Our studies of many shocked shergottites present, contrary to numerous previous reports, ample ...

Dendritic cell chemotaxis in 3D under defined chemokine gradients reveals differential response to ligands CCL21 and CCL19

Marco Pisano, Melody Swartz, Ulrike Haessler, Mingming Wu

Dendritic cell (DC) homing to the lymphatics and positioning within the lymph node is important for adaptive immunity, and is regulated by gradients of CCL19 and CCL21, ligands for CCR7. Despite the importance of DC chemotaxis, it is not well understood ho ...
