Abstract:

A connection procedure for finding by rearrangement a path for multirate, multicast traffic through an SDH cross-connect with subnetwork connection protection. If no free path for a new payload through the SDH switching hardware is available, the switching procedure looks for a path that is adequate and blocked by the least existing payload capacity. If the hunt is successful, the procedure rearranges the existing connections to make possible a path for the new payload. The procedure does not interrupt the existing connections; thus it is a "hitless" procedure. Connections for existing payloads that must be moved to make way for the new payload are queued and the connection procedure is applied recursively, to each in turn, until the queue is empty.

Abstract:

Hollow, protein vesicles are provided. The protein vesicles can be loaded with desired cargo to be delivered to a subject, for example a human. One embodiment provides a protein vesicle made of a protein membrane surrounding a hollow core. The protein membrane includes a first and a second modular protein amphiphile. The first modular protein amphiphile includes a hydrophobic block and a first hydrophilic protein binding block. The second modular protein amphiphile includes a variable polypeptide block and a second hydrophilic protein binding block that binds to the first hydrophilic protein binding block. The first and second protein amphiphiles self-assemble to form the hollow, protein vesicle.
