摘要:
The present invention discloses a remote radio unit and a base station system. The remote radio unit includes an active part and a passive part, where the active part and the passive part are placed respectively on an active module and a passive module that are independent of each other and the active module and the passive module are connected via a pluggable connecting device. Because the passive part is more reliable and less liable to breakdown than the active part, when the active part needs to be repaired, it is unnecessary to dismantle the entire unit. Therefore, the repair is easier and faster and the repair cost is lower. The operation reliability of the base station system is also improved.

Disclosed herein are methods for preparing and using porous, crystalline biomimetic bioactive compositions of calcium phosphate with at least one therapeutic agent. The bioactive composition has strong adsorption properties for therapeutic agents which adsorb to the calcium phosphate with a high affinity. The bioactive composition also provides a sustained release implant that can be used for localized delivery of therapeutic agents. This localized delivery of therapeutic agents, promotes repair, healing, or regeneration of hard and soft tissues.

An apparatus for producing a biomimetic coating on an implantable article is provided. The apparatus includes an outer reactor for containing a biomimetic coating solution and an inner reactor arranged within the outer reactor. The inner reactor is smaller than the outer reactor so as to define a space between the inner and outer reactors. The apparatus also includes a pump system for circulating the biomimetic coating solution. The pump system is arranged to operate in the space between the inner and outer reactors. The inner reactor includes a flow control system that is selectively operable to control the flow of biomimetic coating solution between the outer and inner reactors.

A data operating method, system, client, and data server are provided. The method includes: sending a write request of a file to a data server, where the write request includes identifiers of sub-data blocks constituting the file; receiving mappings between the identifiers of the sub-data blocks and storage servers returned by the data server according to the write request; and writing the sub-data blocks to the corresponding storage servers according to the mappings. With the present invention, whether the identifiers of the sub-data blocks are saved may serve as a basis for determining whether the sub-data blocks are written, thus ensuring that no duplicate data is stored in the system and increasing the storage space of the system.
摘要:
The invention provides novel dental enamel inspired materials for biomedical and dental applications. The materials are apatite-like calcium phosphate complexes and may comprise apatite, octacalcium phosphate crystals, or mixtures thereof. In one embodiment, the materials (calcium phosphate coatings) are mixtures of crystals of apatite and its precursor, octacalcium phosphate, nucleated on a titanium surface. They are prepared using a chemical process leading to the formation of biological apatite which is similar to that found in natural bone and teeth. In one embodiment, the materials are prepared by placing a titanium substrate in a supersaturated calcifyng solution containing native or purified recombinant amelogenins. The presence of the amelogenins modulates apatite crystal growth to mimic in vivo apatite crystal formation. Applications for the materials include, without limitation, dental tissue (enamel, dentin, cementum) replacement, orthopeadic implants for bone repair, and coatings for improving the biocompatibility and bone regeneration capability of currently available implants or medical devices made of metallic, polymeric, ceramic or composite materials.
