Abstract: A system includes a plurality of drug libraries, at least one comprising multiple droplets of multiple drugs, each drug associated with a corresponding unique drug identifier in the system, and a live cell library comprising multiple live cells or live cell lines, each live cell associated with a corresponding unique cell or cell line identifier in the system. A plurality of junctions combining drug droplets from the drug libraries and a live cell from the live cell library. At least one of said drug libraries produces a random stream of heterogenous drug droplets, the drug droplets corresponding to drugs in said drug libraries.

Abstract: Apparatus for creating cavities in edible material includes a cylindrical hollow tube having a distal end that is adapted to serve as a cutting edge and a core removal blade extending inward from the cutting edge part way across the tube.

Abstract: A system and a method for automatic detection of physical network topology, by correlating information from computers connected to the network. Preferably, this information is gathered through the operation of a plurality of agents, which are distributed throughout the network and which are operated by a computer connected to the network. More preferably, the agents exchange information in order to at least partially determine the physical topology of the network. In addition, information is preferably gathered from other sources of physical topology information, such as bridging tables from network switches. The physical topology is preferably built by first determining the relative location of the agents, such as the segment of the network on which the agent is located. Next, switches and other connectivity elements are added in order to connect these segments, and additional segments are created from other sources of information. The remaining connections are then determined.

Abstract: A system and a method for automatic analysis of the traffic topology map of the network, by correlating information from agents which are in communication with the network. The physical topology map is preferably used as a foundation for the traffic mapping process, in order to indicate how the physical components are connected. Preferably, the traffic information is gathered through the operation of a plurality of agents, which are distributed throughout the network according to the physical topology map and which are operated by a computer or other electronic device connected to the network. The traffic mapping process then analyzes the traffic flow between the agents. Thus, the exact process by which the physical topology map is determined is not important.
