Abstract: A method and system for transferring noncontiguous messages group including assembling a set of data into a series of transmission packets, packaging a description of the layout of the transmission packets into description packets and then places each description packet into a local buffer while maintaining a count of the number of description packets, transfers each description packet into a transmit buffer for transmission to at least one receiving node, identifies the data packets, and forwards each data packet to the transmit buffer for transmission to the at least one receiving node. The receiving node receives the transmission packets, identifies each packet as a description packet or data packet, places the description packets in a local buffer for storage until the description is complete, places each description packet into a user data buffer, stores data packets in a local queue until the description is complete, then transfers the data packets to the user buffer.

Abstract: The present invention relates to the finding that C-terminal loop and propeller loop and regions thereof of the DPP-IV family of prolyl dipeptidases play an important role in dimer formation. The present invention further provides purified polypeptides comprising an amino acid sequence that mimics conserved amino acids in at least one of a C-terminal loop and a propeller loop of the dimer interface of the DPP-IV family of prolyl dipeptidases sufficient to prevent dimerization of a member of that family. Such polypeptides and other agents serve to disrupt the activity of the DPP-IV family of prolyl dipeptidases.

Abstract: A system and methods are provided for removal of undesired portions of a fruit or vegetable, such as removal of calyxes from strawberries before they are flash frozen. An automated process for high-throughput fruit or vegetable calyx removal includes a loading system, an identification system, and a removal system. The loading system is configured to transport the fruit or vegetable through the automated process. The loading system may also orient the fruits or vegetables along an axis of the fruit and or align the fruit or vegetables in a desired pattern, orientation, and/or arrangement. The identification system is configured to locate the calyx and determines calyx position data and an optimal cutting path for individual fruit. The removal system uses data received from the identification system to separate the calyx from the fruit or vegetable.
