Abstract: The general problem of pattern change discovery between high-dimensional data sets is addressed by considering the notion of the principal angles between the subspaces is introduced to measure the subspace difference between two high-dimensional data sets. Current methods either mainly focus on magnitude change detection of low-dimensional data sets or are under supervised frameworks. Principal angles bear a property to isolate subspace change from the magnitude change. To address the challenge of directly computing the principal angles, matrix factorization is used to serve as a statistical framework and develop the principle of the dominant subspace mapping to transfer the principal angle based detection to a matrix factorization problem. Matrix factorization can be naturally embedded into the likelihood ratio test based on the linear models. The method may be unsupervised and addresses the statistical significance of the pattern changes between high-dimensional data sets.

Abstract: The present invention relates to compositions and methods for calcifying dental tissue, e.g., preventing or treating dental hypersensitivity. An oral composition of arginine bicarbonate and calcium carbonate promotes the formation of dentinal tubule plugs aided by combining calcium and phosphate in the fluid. In a specific example, an arginine bicarbonate/calcium carbonate mixture blocked dentinal tubules in a model system. In addition to treating dentinal sensitivity, the compositions and methods of the invention provide for calcifying exposed tooth pulp, calcifying the base or all of a pit or fissure in a tooth, and treating a carious lesion.

Abstract: A method of plating a metal on a hydrophobic polymer, especially in the shape of small particles, involves: (a) contacting a surface of hydrophobic polymer substrate with a polycation such as poly(allylamine hydrochloride) to create a treated surface; (b) contacting the treated surface with a catalyst; and then (c) immersing the surface in a electroless metal plating bath to create a coating of metal on the surface. Metals include copper, silver, gold, nickel and cobalt. Catalysts are selected from compounds containing palladium, platinum, tin, copper, or nickel salts. Damaging surface treatments such as etching by plasma or acid are avoided.

Abstract: A fiberized single photon sensitive spectrometer on a 32-channel PMT sensor is highly sensitive with broad detection dynamic range. The spectrometer enables accurate and high speed detection, identification and analysis of biological samples labeled with multiple fluorescent markers, such as compositions of multi-color fluorescence signals or radiation emitted by multiple fluorescence dyes. A fiberized optical input of the spectrometer allows an easy and efficient coupling to any measurement system based on fiber collection of the analyzed fluorescence. The spectrometer provides highly accurate DNA sequencing. A 32 channel PMT single photon detector has a detection dynamic range of more than 20 bits and has a frame rate of about 3300 frames per second. The dynamic range of the detector's pixels reaches 108 photocounts per second.

Abstract: A direct double-frequency ripple current control in a two-stage high-frequency-link (HFL) based fuel cell converter that can achieve low-frequency ripple free input current without using large electrolytic capacitors is provided. To eliminate the double-frequency ripple current disturbance introduced by the single-phase inverter load, a proportional-resonant (PR) controller is developed to achieve an extra high control gain at designed resonant frequency. This high gain can be viewed as the virtual high impedance for blocking the double-frequency ripple energy propagation from inverter load to fuel cell stack. More particularly, the proposed control system can realize the utilization of all capacitive ripple energy sources in the system by regulating all the capacitors to have large voltage swing and the voltage swing is synchronized to keep real-time balancing of the transformer primary-side and secondary-side voltages.
