The present invention provides methods and compositions for attenuating expression of a target gene in vivo. In general, the method includes administering RNAi constructs (such as small-interfering RNAs (i.e., siRNAs) that are targeted to particular mRNA sequences, or nucleic acid material that can produce siRNAs in a cell), in an amount sufficient to attenuate expression of a target gene by an RNA interference mechanism. In particular, the RNAi constructs may include one or more modifications to improve serum stability, cellular uptake and/or to avoid non-specific effect. In certain embodiments, the RNAi constructs contain an aptamer portion. The aptamer may bind to human serum albumin to improve serum half life. The aptamer may also bind to a cell surface protein that improves uptake of the construct.

A multimedia object retrieval and annotation system integrates an annotation process with object retrieval and relevance feedback processes. The annotation process annotates multimedia objects, such as digital images, with semantically relevant keywords. The annotation process is performed in background, hidden from the user, as the user conducts normal searches. The annotation process is “semi-automatic” in that it utilizes both keyword-based information retrieval and content-based image retrieval techniques to automatically search for multimedia objects, and then encourages users to provide feedback on the retrieved objects. The user identifies objects as either relevant or irrelevant to the query keywords and based on this feedback, the system automatically annotates the objects with semantically relevant keywords and/or updates associations between the keywords and objects. As the retrieval-feedback-annotation cycle is repeated, the annotation coverage and accuracy of future searches continues to improve.

A system and method for uniquely identifying an SIP device extends the SIP communications protocol with an end point identifier, carried for example in the header of an SIP transmission. The end point identifier is useful for routing, registration, subscription, and authentication. The end point (device) of a given user epid can be uniquely identified by creating a key from an epid and a user's address-of-record (URI). This in turn enables improved connection management and security association management when the connections/IP addresses are transient, such as when HTTPS tunneling is used.
