摘要:
This invention relates to biotechnology, more particularly, to water-soluble polymeric delivery systems for the imaging, evaluation and/or treatment of rheumatoid arthritis and other inflammatory diseases. Using modern MR imaging techniques, the specific accumulation of macromolecules in arthritic joints in adjuvant-induced arthritis in rats is demonstrated. The strong correlation between the uptake and retention of the MR contrast agent labeled polymer with histopathological features of inflammation and local tissue damage demonstrates the practical applications of the macromolecular delivery system of the invention.

An axial flow impeller includes a hub, at least three base blades, and a cover blade detachably mounted to each base blade. When the impeller is applied in a medium environment having a high density and viscosity, the impeller will meet the requirement only by virtue of the base blade with the cover blade being removed. When the impeller is applied in a medium environment having low density and viscosity, the cover blade can be mounted in the front and/or rear of the base blade in order to improve the efficiency of the impeller. In this case, the consumption of electrical power can be reduced significantly while producing an equivalent propulsive force, thereby being advantageous for energy conservation. Therefore, the impeller can be adaptable to different medium environments and efficiency requirements, and thus can have good adaptability, need minimal investment cost and can be convenient to use.

Embodiments of the present invention provide a method and an apparatus for decoding and encoding a video, and a method and an apparatus for predicting a direct current coefficient. The video decoding method includes: receiving current frame image information sent by an encoding end, where the current frame image information includes prediction value information, and the prediction value information includes at least one intra-frame direct current DC prediction value; selecting a prediction value from the at least one intra-frame DC prediction value in the prediction value information as an intra-frame DC prediction value of the current image. Through the embodiments of the present invention, flexibility of encoding and decoding a video can be improved.
摘要:
A medical system includes one or more medical body area network (MBAN) systems. Each MBAN system includes one or more MBAN devices which acquire and communicate patient data with a hub device via short-range wireless communication. The communication of the patient data via the short-range wireless communication is within a predefined spectrum. The hub device receives patient data communicated from the one or more MBAN devices and communicates with a central monitoring station via a longer range communication. A MBAN channelization scheme defines one or more overlapping channels in the predefined spectrum and a MAC parameter dynamically enables or disables access to each defined channel. A channel regulator manages the MBAN utilization of the predefined spectrum by setting the MAC parameter to dynamically enable/disable the one or more predefined MBAN channels within the predefined spectrum.

A medical system includes one or more MBAN devices which acquire and communicate patient data. One or more medical body area network (MBAN) systems include the one or more MBAN devices communicating the patient data with a hub device via short-range wireless communication. The communication of the patient data via the short-range wireless communication being within a predefined spectrum. The hub device receives patient data communicated from the one or more MBAN devices, communicates with a central monitoring station via a longer range communication and one or more access points (AP), and determines the location of the MBAN system in reference to a healthcare facility. The one or more MBAN devices are inhibited from transmitting within the predefined spectrum when the MBAN hub device is located outside the healthcare facility.

A method, system, and server for issuing directory tree data and a client. The method includes: pre-storing Identities (IDs) for data blocks obtained by dividing directory tree data according to an agreed protocol, and generating and storing validity IDs for the data blocks according to the agreed protocol; receiving, by a directory tree server, an ID and a validity ID of a data block that the client requests to download, and querying for a validity ID of a data block having the same ID at a directory tree server side. If the validity ID of the data block having the same ID at the directory tree server side is the same as the validity ID received from the client, issuing a matching success message to the client; otherwise, issuing, a matching failure message and the data block at the directory tree server side having the same ID to the client.
