摘要:
This invention relates generally to the field of cell separation or isolation. In particular, the invention provides a method for separating cells, which method comprises: a) selectively staining cells to be separated with a dye so that there is a sufficient difference in a separable property of differentially stained cells; and b) separating said differentially stained cells via said separable property. Preferably, the separable property is dielectrophoretic property of the differentially stained cells and the differentially stained cells are separated or isolated via dielectrophoresis. Methods for separating various types of cells in blood samples are also provided. Centrifuge tubes useful in density gradient centrifugation and dielectrophoresis isolation devices useful for separating or isolating various types of cells are further provided.

The present invention relates generally to amino acid sequences obtainable from SOCS proteins and which are capable of interacting with intracellular molecules. The present invention further relates to nucleic acid molecules encoding said amino acid sequences. The amino acid sequences and the nucleic acid molecules encoding same of the present invention are useful in modulating degradation of proteinaceous molecules such as but not limited to SOCS proteins and proteinaceous molecules associate therewith. The present invention provides a mechanism for modulating cytokine or cytokine-like molecule signaling by modulating the degradation of activated signal transduction molecules or their negative regulators, i.e. the SOCS proteins.

摘要:
A method for fabricating a MEMS device comprises providing a substrate having a back side, a front side opposite to the back side and a periphery portion. A desired microstructure is formed on the back side of the substrate. The substrate is then supported for rotation. A precursor solution is deposited on the front side of the substrate during rotation so that a thin film layer may be formed thereon. During formation of the thin film layer, the substrate is supported and rotated that the microstructure formed on the back side is protected.

Provides methods for tracing and identifying a piracy in a wireless rights management system, wherein the content provider allow the protected digital content to be super-distributed, when unauthorized holding a pirated copy of the protected digital content is detected, based on the gateway controlling ability of the wireless operator within the wireless digital rights management system, a specific fingerprint is embedded in or removed from the protected digital content so as to trace the suspected persons and further identify the pirate. The fingerprint is related to information of a suspected person holding the protected digital content without authorization. A process of screening singles out highly suspected persons. Therefore the operator can determine whether the suspected person is a real pirate by comparing the similarity of the pirated version of content and the version held by the suspected person, and the exact tracing and identifying is achieved.
摘要:
A composition suitable for tantalum chemical-mechanical polishing (CMP) comprises an abrasive, an organic oxidizer, and a liquid carrier therefor. The organic oxidizer has a standard redox potential (E0) of not more than about 0.5 V relative to a standard hydrogen electrode. The oxidized form comprises at least one pi-conjugated ring, which includes at least one heteroatom directly attached to the ring. The heteroatom can be a N, O, S or a combination thereof. In a method embodiment, a CMP composition comprising an abrasive, and organic oxidizer having an E0 of not more than about 0.7 V relative to a standard hydrogen electrode, and a liquid carrier therefor, is utilized to polish a tantalum-containing surface of a substrate, by abrading the surface of the substrate with the composition, preferably with the aid of a polishing pad.

The invention provides partially stabilised zirconia and alumina based electro-static dissipative or ESD ceramic compositions. The proposed ceramic compositions include specific amounts of dopants comprising one or more metal oxides selected from iron oxide, chromium oxide and titanium oxide. The proposed ESD ceramic materials are made into useful industrial products by injection moulding and sintering technology. A novel binder system may optionally be used to make injection mouldable feedstock. Useful products produced by the invention include, for example, ESD ceramic tweezers tips, ESD ceramic dispensing needles, ESD ceramic scissors and blades and ESD ceramic wire bonding capillaries which retain their ESD properties at relatively low temperatures, for example, service temperatures from 25 to 500° C.
