摘要:
The present invention relates to a water-in-oil-in-water multiple emulsion system and a method for preparation thereof, characterized by hydrodynamically stabilizing the multiple emulsion system by using hydrodynamic dual stabilization (HDS) technology. The HDS technology hydrophobizes water molecules in the internal aqueous phase by using a hydrogen bonding inhibitor and by improving the aggregating force between water molecules in the internal aqueous phase by using a water molecule aggregating agent.
摘要:
A computer-implemented method of defining a set of annotation elements to map a concept to electronic data as input data; generating a mapping rule, according to the set of annotation elements defined and a sample of the input data; mapping the concept to the input data by applying the mapping rule to the input data; and generating a semantic instance of the input data based upon the mapping of the concept to the input data. The set of annotation elements to map the concept to the input data are a selected ontology corresponding to the input data, a selected ontology concept from the selected ontology, a mapping of a word or word phrase in the sample input data to the selected ontology concept from the selected ontology, and a pattern of the mapped word or word phrase relative to a structure of the sample input data.

Provided is a small form factor optical/magnetic disk including an integrated metal hub and a disk plate. The integrated metal hub includes a circular upper metal hub and a circular lower metal hub integrally formed with and disposed under the upper metal hub. The circular lower metal hub has a smaller diameter smaller than the upper metal hub. A central hole is formed in central portions of the upper and lower metal hubs and passes through the upper and lower metal hubs. The disk plate has a through-hole that is formed in a central portion and is directly associated with the integrated metal hub, and a recess that is formed around the through-hole and allows the upper metal hub to be mounted therein. Since the central portion of the small form factor optical/magnetic disk is not thick, the small form factor optical/magnetic disk can contribute to an ultra thin small form factor information storage device. Also, since manufacturing processes are simple, price and quality competitiveness can be enhanced.

An active handoff system and method of a dual mode terminal capable of connecting to a wireless network, such as wireless local area network (LAN), and a mobile communication system are provided. The handoff method includes the steps of assigning, at a packet data service node of the mobile communication system, an IP address to the dual mode terminal connected to the service network, establishing, at the packet data service node, a tunneling path to the wireless LAN when the dual mode terminal moves from the mobile communication network to the wireless LAN, and disconnecting, at the packet data service node, the tunneling path to the wireless LAN, and establishing a tunneling path to another packet data service node whose Internet Protocol (IP) address has been established by the packet data service node, when the dual mode terminal moves from the wireless LAN to the mobile communication system. A dual mode terminal that moves from a 3G mobile communication system to a wireless network in an active state maintains an existing IP address assigned from an active 3G mobile communication system so that the dual mode terminal can maintain an upper layer session and transmit an IP packet to a terminal located in a 3G mobile communication system.

A method for preparing a multilayer of nanocrystals. The method includes the steps of (i) coating nanocrystals surface-coordinated by a photosensitive compound, or a mixed solution of a photosensitive compound and nanocrystals surface-coordinated by a material miscible with the photosensitive compound, on a substrate, drying the coated substrate, and exposing the dried substrate to UV light to form a first monolayer of nanocrystals, and (ii) repeating the procedure of step (i) to form one or more monolayers of nanocrystals on the first monolayer of nanocrystals. Further, an organic-inorganic hybrid electroluminescence device using a multilayer of nanocrystals prepared by the method as a luminescent layer. The luminescent efficiency and luminescence intensity of the electroluminescence device can be enhanced, and the electrical properties of the electroluminescence device can be controlled by the use of the multilayer of nanocrystals as a luminescent layer.

This application relates to monomers of the general formula (I) for the preparation of PNA (peptide nucleic acid) oligomers and provides method for the synthesis of both predefined sequence PNA oligomers and random sequence PNA oligomers: wherein E is nitrogen or C—R′; J is sulfur or oxygen; R′, R1, R2, R3, R4 is independently H, halogen, alkyl, nitro, nitrile, alkoxy, halogenated alkyl, halogenated alkoxy, phenyl or halogenated phenyl, R5 is H or protected or unprotected side chain of natural or unnatural α-amino acid; and B is a natural or unnatural nucleobase, wherein when said nucleobase has an exocyclic amino function, said function is protected by protecting group which is labile to acids but stable to weak to medium bases in the presence of thiol.
摘要:
A solid-state transducer is disclosed. The transducer comprises a semi-conductor substrate forming a support structure and having an opening. A thin-film structure forming a diaphragm responsive to fluid-transmitted acoustic pressure is disposed over the opening. The transducer further includes a plurality of semi-conductor supports and tangential arms extending from the diaphragm edge for connecting the periphery of the diaphragm to the supports. The tangential arms permit the diaphragm to rotate relative to the supports to relieve film stress in the diaphragm. The transducer still further includes a plurality of stop bumps disposed between the substrate and the diaphragm. The stop bumps determine the separation of the diaphragm from the substrate when the transducer is biased.
