Inventor: WANG JOSEPH Y
IPC: G06T7/00
Filed: 1999-09-17
Abstract: Higher dimensionality data is subject to a hierarchical visualization to allow the complete data set to be visualized in a top-down hierarchy in terms of clusters and sub-clusters at deeper levels. The data set is subject to standard finite normal mixture models and probabilistic principal component projections, the parameters of which are estimated using the expectation-maximization and principal component analysis under the Akaike Information Criteria (AIC) and the Minimum Description Length (MDL) criteria. The high-dimension raw data is subject to processing using principal component analysis to reveal the dominant distribution of the data at a first level. Thereafter, the so-processed information is further processed to reveal sub-clusters within the primary clusters. The various clusters and sub-clusters at the various hierarchical levels are subject to visual projection to reveal the underlying structure. The inventive schema has utility in all applications in which high-dimensionality multi-variate data is to be reduced to a two- or theree-dimensional projection space to allow visual exploration of the underlying structure of the data set.

Title: Modulateurs d'apoptose interagissant avec le gene de la maladie de huntington
Inventor: RASPER DITA M
IPC: A61K48/00
Filed: 1999-05-27
Abstract: Une famille de protéines, notamment une protéine humaine spécifique dénommée HIP1, a été identifiée comme interagissant avec le produit génique d'un gène HD normal (16 unités récurrentes CAG) et étendu (plus de 44 unités récurrentes CAG). L'expression de la protéine HIP1 s'est révélée enrichie dans le cerveau. Une analyse de la séquence de cette protéine HIP1 a indiqué qu'elle renfermait un domaine effecteur de mort (DED) laissant supposer une fonction apoptotique. Il semble ainsi qu'une fonction normale de la huntingtine peut être de se fixer à HIP1 et à des modulateurs d'apoptose en rapport, ce qui réduit son aptitude à stimuler la mort cellulaire. Dans la mesure où une huntingtine étendue exécute moins bien cette fonction, il existe un renforcement dans la mort cellulaire modulée par HIP1 chez des individus ayant une unité récurrente dans le gène HD. Cette compréhension du rôle vraisemblablement joué par la huntingtine et par la protéine HIP1 ou par des protéines apparentées (collectivement : ?protéines de modulation de l'apoptose par HIP1?) dans la pathologie de la maladie de Huntington offre plusieurs possibilités thérapeutiques. Tout d'abord, dans la mesure où la fonction de la huntingtine dépend, apparemment, au moins partiellement de son aptitude à interagir avec les protéines de modulation de l'apoptose par HIP1, une expression ajoutée (par exemple par thérapie génique) d'une huntingtine normale (non étendue) ou de la région de fixation d'HIP d'une huntingtine devrait avoir un effet bénéfique du point de vue thérapeutique. Il est également possible d'utiliser d'autre peptides interagissant avec le domaine DED pour masquer et réduire l'interaction de ces protéines de modulation avec un complexe de signalisation de mort. Il est également possible d'introduire, en utilisant, par exemple, des techniques de thérapie génique, une forme mutante de la protéine HIP dont le domaine DED a été détruit. Dans la mesure où ces protéines de modulation de l'apoptose se sont révélées s'associer d'elles-mêmes, une protéine dont le domaine DED a été détruit peut concurrencer une protéine HIP endogène dans la formation de ces associations, ce qui réduit la quantité de protéine HIP active du point de vue apoptotique.

Title: Control apparatus and method for efficiently heating a fuel processor in a fuel cell system
Inventor: DOAN TIEN M
IPC: B60L11/18
Filed: 2001-01-10
Abstract: A control apparatus and method for efficiently controlling the amount of heat generated by a fuel cell processor in a fuel cell system by determining a temperature error between actual and desired fuel processor temperatures. The temperature error is converted to a combustor fuel injector command signal or a heat dump valve position command signal depending upon the type of temperature error. Logic controls are responsive to the combustor fuel injector command signals and the heat dump valve position command signal to prevent the combustor fuel injector command signal from being generated if the heat dump valve is opened or, alternately, from preventing the heat dump valve position command signal from being generated if the combustor fuel injector is opened.

Title: Dispersion free optical filters
Inventor: BOUEVITCH OLEG
IPC: G02B6/34
Filed: 2001-05-03
Abstract: The filtering of optical signals, and in particular the interleaving/de-interleaving of optical signals is becoming a necessary step in Dense-Wavelength Division Multiplexing (D-WDM), because of a requirement for smaller channel spacing due to higher levels of traffic. Finite Impulse Response (FIR) filters, including lattice and birefringent waveplate versions, are a particular type of optical filter used for interleavering/de-interleavering optical channels, which can be defined by their transfer function H(f). To ensure dispersion free filtering, the present invention provides a cascaded optical filter, comprising two optical filters, wherein the transfer function of the second filter is the complex conjugate of the first filter, i.e. H2(f)=H1*(f), or the complex conjugate of the first filter H1*(f) multiplied by the transfer function of a dispersion free optical filter G(f). In the waveplate version, the relationship between the crystal angle of the waveplates and the polarization of the input light is manipulated to ensure that the second filtering step eliminates the dispersion caused by the first. Since the polarization of the light can be altered between the first and second filters, birefringent filters can be conceived using a single stack of waveplates that are passed through twice. In lattice filters, a symmetric pulse response is an indication that the cascaded filter is dispersion free. In this case, the second filter is the inverse of the first filter, which individually would give the opposite pulse responses, but together provide a symmetric pulse response.
