This paper investigates the use of DUET, a recently proposed blind source separation method, as front-end for missing data speech recognition. Based on the attenuation and delay estimation in stereo signals soft time-frequency masks are designed to extract a target speaker from a mixture containing multiple speech sources. A postprocessing step is introduced in order to remove isolated mask poi...
The nucleic acid sequence bank now contains 161 mRNAs, 43 new genes are added. One sequence, that of B. mori fibroin, is dropped due to uncertainty on the starting point for translation. Frequencies of all codons are given for each gene added and for each genome type in the total bank. A new series of correspondence analyses on codon use is presented, substantiating the genome hypothesis. Inter...

This paper reports on initial stages of research leading to the development of an intermedia performance Counterlines a duet for Disklavier and Wacom Cintiq, in which both performers generate audiovisual gestures that relate to each other contrapuntally. The pianist generates graphic elements while playing music and the graphic performer generates piano notes by drawing lines. The paper focuses...
In NightDriving, a semi-transparent projection scrim filling the width and height of the stage brings real and virtual dancers into the same field of view. The resulting shared visual space contains two kinds of representation: a “here and now” embodiment of the dance through the live performers, and projected dance film imagery of virtual figures in counterpoint to the live dancers. This share...
In this paper we present a new source separation method based on dynamic sparse source signal models. Source signals are modeled in frequency domain as a product of a Bernoulli selection variable with a deterministic but unknown spectral amplitude. The Bernoulli variables are modeled in turn by first order Markov processes with transition probabilities learned from a training database. We consi...
This paper deals with blind speech separation of convolutive mixtures of sources. The separation criterion is based on Oriented Principal Components Analysis (OPCA) in the frequency domain. OPCA is a (second order) extension of standard Principal Component Analysis (PCA) aiming at maximizing the power ratio of a pair of signals. The convolutive mixing is obtained by modeling the Head Related Tr...
Monte Carlo simulations are more and more popular trend in nuclear medicine imaging. They were also widely used in radiotherapy and brachytherapy with use of more general simulation software. GATE (Geant4 Application for Tomographic Emission) is a platform developed on general Monte Carlo code designed for simulating and tracking the passage of particles through matter (Geant4) but is specifica...
Neurotransmission in the brain critically depends on the maintenance of synapses as well as on regulated synaptic protein turnover. How synaptic proteostasis is held in check has remained largely enigmatic. A new paper in The EMBO Journal reports that the active zone proteins Piccolo and Bassoon put a brake on presynaptic protein turnover by restraining the activity of the E3 ubiquitin ligase S...
