Approximation of Event Probabilities in Noisy Cellular Processes

Maria-Emanuela-Canini Mateescu, Verena Wolf

Molecular noise, which arises from the randomness of the discrete events in the cell, significantly influences fundamental biological processes. Discrete-state continuous-time stochastic models (CTMC) can be used to describe such effects, but the calculati ...

Stable computation of probability densities for metastable dynamical systems

Lionel Walter

Whenever the invariant stationary density of metastable dynamical systems decomposes into almost invariant partial densities, its computation as eigenvector of some transition probability matrix is an ill-conditioned problem. In order to avoid this computa ...

Active Antenna Selection in Multiuser MIMO Communications

Ali H. Sayed

The paper develops a dynamic antenna scheduling strategy for downlink MIMO communications, where a subset of the receive antennas at certain users is selectively disabled. The proposed method improves the signal-to-leakage-plus-noise (SLNR) ratio performan ...

On the condition of a complex eigenvalue under real perturbations

Daniel Kressner

We investigate the condition number for a complex eigenvalue of a real matrix under real perturbations. Based on an explicit formula, it is shown that this number is never smaller than 1/root2 times the corresponding condition number with respect to comple ...

Low cost duration modelling for noise robust speech recognition

Hervé Bourlard

State transition matrices as used in standard HMM decoders have two widely perceived limitations. One is that the implicit Geometric state duration distributions which they model do not accurately reflect true duration distributions. The other is that they ...

Markov chain modeling of chaotic wandering in simple coupled chaotic circuits

Martin Hasler

In this study, chaotic wandering phenomenon observed in simple coupled chaotic circuits is modeled by Markov chains. As coupling parameter increases, the solution of the coupled chaotic circuits starts to wander chaotically over 6 different phase states wh ...

Overdispersion phenomenon in stochastic modeling of precipitation

Marc Parlange

Simple stochastic models Rt to time series of daily precipitation amount have a marked tendency to underestimate the observed (or interannual) variance of monthly (or seasonal) total precipitation. By considering extensions of one particular class of stoch ...

Determination of Electric-Dipole Moments and Transition-Probabilities of Low-Lying Singlet-States of CO

Marcel Drabbels

Transitions from the X 1SIGMA+ (v = 0) ground state of the carbon monoxide molecule to the electronically excited A 1PI(v = 0), B 1SIGMA+ (v = 0), and C 1SIGMA+ (v = 0) states have been studied by 2-photon laser induced fluorescence spectroscopy. Accurate ...
