This article provides the mathematical foundation for stochastically continuous affine processes on the cone of positive semidefinite symmetric matrices. This analysis has been motivated by a large and growing use of matrix-valued affine processes in finan ...
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 ...
We develop new algebraic algorithms for scalar and vector network coding. In vector network coding, the source multicasts information by transmitting vectors of length L, while intermediate nodes process and combine their incoming packets by multiplying th ...

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 ...
Mitochondrial Ca2+ signals have been proposed to accelerate oxidative metabolism and ATP production to match Ca2+-activated energy-consuming processes. Efforts to understand the signaling role of mitochondrial Ca2+ have been hampered by the inability to ma ...
The research work reported in this dissertation is aimed to develop efficient and stable numerical schemes in order to obtain accurate numerical solution for viscoelastic fluid flows within the spectral element context. The present research consists in the ...
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 ...

Engineered artificial microenvironments hold enormous potential as models to study developmental, physiological, pathological, and regenerative processes under highly defined conditions. Such platforms aim at bridging the gap between traditional in vitro 2 ...
Ferrofluids are suspensions of ferromagnetic nano-particles in a fluid carrier (typically oil). They have the property to change their shape when subjected to a magnetic field following the flux lines. Often used in design and art, the goal of this project ...
