Abstract:
A method and system for verifying an account used by a user to open or lock a service account through an electronic device is disclosed. The electronic device sends an open or lock request for an identification account and the service account to a cloud server via the Internet. The cloud server comparisons the sent identification account and the service account with the identification account and the service account in a database stored on the cloud server. The cloud server sends the open or lock request to a service provider if the comparison results indicate a matching result. The service provider opens or locks the service account corresponding to the identification account.
Abstract:
A semiconductor device and a method of fabricating the same are described. A substrate having a PMOS area and an NMOS area is provided. A high-k layer is formed on the substrate. A first cap layer is formed on the high-k layer in the PMOS area, and a second cap layer is formed on the high-k layer in the NMOS area, wherein the first cap layer is different from the second cap layer. A metal layer and a polysilicon layer are sequentially formed on the first and second cap layers. The polysilicon layer, the metal layer, the first cap layer, the second cap layer and the high-k layer are patterned to form first and second gate structures respectively in the PMOS and NMOS areas. First source/drain regions are formed in the substrate beside the first gate structure. Second source/drain regions are formed in the substrate beside the second gate structure.

Abstract:
Novel derivatives of phencyclidine are provided as precursors for conjugating to antigenic proteins for the preparation of antibodies which bind to phencyclidine or conjugation to enzymes for use as reagents in immunoassays. The combination of the antibodies and enzyme conjugates provide a sensitive and rapid assay for phencyclidine.
Abstract:
A kit for inactivating interfering binding proteins in a immunoassay for a member of a specific binding pair (sbp). The method comprises including in an assay medium containing a sample suspected of containing an sbp member and an interfering binding protein an effective amount of a water soluble compound having two substituted or unsubstituted phenyl groups linked to a common atom. When the sbp member or its sbp partner has two phenyl groups linked to a common atom, the compound has a number of-groups other than hydrogen attached to the phenyl groups and the atom that differs by at least two from the number of such groups on the sbp member. When the sbp member or its sbp partner has two phenyl groups linked to a common atom and the binding protein is not an antibody, the compound has only one group other than hydrogen attached to a phenyl group or the common atom. The methods have particular application in avoiding-cross-reactivity of non-analyte materials in a sample with immunachemical reagents used in such assay. The methods-have application also in disrupting complexer between an analyte to be determined and other materials to that one can accurately determine the amount of an analyte in a sample.
Abstract:
Novel compounds and assay methods are provided for determining the presence of lithium in serum, plasma, urine or other sample without deproteinization. The novel compounds are water soluble derivatives of TMC-crownformazans and provide signal enhancement by increased absorbance of the dye-lithium complex over the dye anion.
Abstract:
Compounds and methods are disclosed for reversibly aggregating particles suspended in a liquid medium. The method comprises combining the liquid medium containing the particles with a polyionic polymer capable of aggregating the particles under conditions suitable for such aggregation. Thereafter, the particles are contacted with a chemical reagent capable of cleaving the polyionic polymer under conditions sufficient to reverse the aggregation. Optionally, magnetic particles are added to the liquid medium in the present method under conditions for non-specific binding and the medium including the aggregates is subjected to a magnetic field gradient to separate the aggregates from the medium. The compounds of the present invention are polyions. The aggregation of the particles is reversible upon contact with chemical agents which cleave at least some of the bonds within the polyionic polymer.
Abstract:
A voltage converter includes a driver, a subsidiary voltage converter, an inductor, a capacitor, and a voltage detection unit. The subsidiary voltage converter generates a driving voltage transmitted to the driver to supply working power to the driver. The driver controls the capacitor to be alternately charged and discharged through the inductor, thereby generating an output voltage and output current between the inductor and the first capacitor. The voltage detection unit detects an electric potential difference of the inductor and generates a reference voltage according to the electric potential difference, and the subsidiary voltage converter receives the reference voltage and adjusts the driving voltage according to the reference voltage.
