Computing Codimensions And Generic Canonical Forms For Generalized Matrix Products

A generalized matrix product can be formally written as Lambda(sp)(p) Lambda(sp-1)(p-1) ... Lambda(s2)(2) Lambda(s1)(1) where s(i) is an element of {- 1,+ 1} and ( A(1), ..., A(p)) is a tuple of ( possibly rectangular) matrices of suitable dimensions. The ...

GPGPU Computation and Visualization of Three-dimensional Cellular Automata

Daniel Thalmann, Stéphane Gobron

This paper presents a general-purpose simulation approach integrating a set of technological developments and algorithmic methods in cellular automata (CA) domain. The approach provides a general-purpose computing on graphics processor units (GPGPU) implem ...

A mixed-precision algorithm for the solution of Lyapunov equations on hybrid CPU-GPU platforms

Daniel Kressner

We describe a hybrid Lyapunov solver based on the matrix sign function, where the intensive parts of the computation are accelerated using a graphics processor (GPU) while executing the remaining operations on a general-purpose multi-core processor (CPU). ...

Genetic evidence for a protective role of the peritrophic matrix against intestinal bacterial infection in Drosophila melanogaster

Bruno Lemaitre, Onya Opota, Olivier Binggeli, Takayuki Kuraishi

The peritrophic matrix (PM) forms a layer composed of chitin and glycoproteins that lines the insect intestinal lumen. This physical barrier plays a role analogous to that of mucous secretions of the vertebrate digestive tract and is thought to protect the ...

Sampling and Reconstructing Diffusion Fields with Localized Sources

Martin Vetterli, Yue Lu, Juri Ranieri, Amina Chebira

We study the spatiotemporal sampling of a diffusion field generated by K point sources, aiming to fully reconstruct the unknown initial field distribution from the sample measurements. The sampling operator in our problem can be described by a matrix deriv ...

Condensed forms for the symmetric eigenvalue problem on multi-threaded architectures

Daniel Kressner

We investigate the performance of the routines in LAPACK and the Successive Band Reduction (SBR) toolbox for the reduction of a dense matrix to tridiagonal form, a crucial preprocessing stage in the solution of the symmetric eigenvalue problem, on general- ...

Interfacial sliding in carbon nanotube/diamond matrix composites

William Curtin, Fabio Pavia

Carbon matrix carbon nanotube (CNT) composites have a broad range of applications because of the exceptional mechanical properties of both matrix and fibers. Since interfacial sliding plays a key role in determining the strength and toughness of ceramic co ...

Chemical Developments in DNP-NMR

Pascal Miéville

The Nuclear Magnetic Resonance (NMR) is an extraordinary tool to understand molecular structures. Its main limitation resides in its relatively low sensitivity when compared with other physico-chemical methods such as Mass Spectrometry (MS) or Optical Spec ...

Parallel Algorithms for Fluid-Structure Interaction Problems in Haemodynamics

Alfio Quarteroni, Simone Deparis, Gilles Fourestey, Paolo Crosetto

The increasing computational load required by most applications and the limits in hardware performances affecting scientific computing contributed in the last decades to the development of parallel software and architectures. In Fluid-Structure Interaction ...

Multipartite polariton entanglement in semiconductor microcavities

Vincenzo Savona, Timothy Chi Hin Liew

We study the entanglement of multiple polariton modes, which results in continuous variable cluster states suitable for quantum computation. Schemes are based on parametric scattering between spin-polarized lower and upper polariton branches in planar micr ...
