Abstract: A nano-structured device for detecting biological analytes, chemical, analytes, cancer and other physiological conditions, includes a carrier substrate, a transducer film disposed over a surface of the carrier substrate, and a dendrimer structure tethered to the transducer film. The transducer film generates a first signal in response to a mechanical stress applied thereto. The first signal indicates the detection of the biological analyte, chemical analyte, cancer or other physiological condition. The dendrimer structure includes a plurality of receptors for binding the biological analyte, the chemical analyte, or one or more biomarkers indicative of cancer or other physiological conditions to the dendrimer structure.

Abstract: This invention discloses new krill oil compositions characterized by having high amounts of phospholipids, astaxanthin esters and/or omega-3 contents. The krill oils are obtained from krill meal using supercritical fluid extraction in a two stage process. Stage 1 removes the neutral lipid by extracting with neat supercritical CO2 or CO2 plus approximately 5% of a co-solvent. Stage 2 extracts the actual krill oils by using supercritical CO2 in combination with approximately 20% ethanol. The krill oil materials obtained are compared with commercially available krill oil and found to be more bioeffective in a number of areas such as anti-inflammation, anti-oxidant effects, improving insulin resistances and improving blood lipid profile.

Abstract: Methods and systems for identifying a local domain for a data packet received at an interface through a network are described herein. In one aspect of the invention, an exemplary method includes extracting the network protocol information from the data packet, determining a local domain ID based on multiple layers of network protocol information simultaneously, and assigning the local domain ID to the data packet. Other methods and systems are also described.

Abstract: A bacteriorhodopsin based chemical sensing architecture based upon the collective response of bacteriorhodopsin and a number of its mutants; the wild type protein and a selection of genetically-engineered variants was able to respond differentially to a selection of amines. The observable response to the presence of a target chemical was manifested through a modulation of bacteriorhodopsin's photokinetic properties, which are monitored through pump-probe techniques using a custom prototype flash photolysis system. Differential responsivity exists at two levels; (1) bacteriorhodopsin proteins (wild-type and genetically-engineered variants) respond differentially upon exposure of a target chemical, and (2) the response pattern exhibited by the proteins differs from chemical to chemical. This dichotomy forms the basis for a BR-mediated chemical sensing technology that is highly sensitive and selective and may therefore discriminate between different chemicals.

Abstract: A binary optical compound formed from a preparation of proteorhodopsin, is provided. The preparation is prepared by dissolving proteorhodopsin in distilled water, where the pH is adjusted to be above 11 either by using sodium hydroxide or an appropriate buffer. The preparation is then illuminated with either white light sources, lasers, or irradiation provided from light-emitting diodes. The necessary duration is intensity dependent, varying from a few seconds to a few minutes, depending upon the source and actinic wavelength. The resulting compound has a long lifespan and may be efficiently transitioned between states.

Abstract: A method, apparatus, and system in which a network system has one or more individual networks. The topology of the first individual network includes two or more service modules. At least one of the service modules is modeled to represent a network element that performs one or more functions to process a packet in a network system. The two or more service modules may be arranged in the first individual network in an arbitrary topology. The packet processing by the two or more service modules is governed by the topology of the first individual network.

Connections between the aligned plasma gas passages are made via coupling tubes each having a first portion inserted into a receiving portion of the passage in the main torch body and a second portion inserted into a receiving portion of the passage in the insulator body. Each inserted portion includes a pair of O-rings spaced apart along the length of the tube for sealing the connection.

Abstract: A method of producing a silicon based alloy is described which comprises melting a silicon alloy containing greater than 50 wt. % silicon and preferably including aluminium. The melted alloy is then inert gas atomized to produce powder or a spray formed deposit in which the silicon forms a substantially continuous phase made up of fine, randomly oriented crystals in the microstructure. The alloy produced by the method has particularly useful application in electronics packaging materials and a typical example comprises an alloy of 70 wt. % silicon and 30 wt. % aluminium. Such an alloy is an engineering material which, for example, is machinable.

Abstract: A method and apparatus for controlling routing within a communication system (10) modifies (258) routing tables (220, 230, 232, 234, 236) located within nodes (150) so that received data packets are not returned directly to their sending nodes. In response to detection (352) of a failed link, a node (150) modifies (354) its routing tables (220, 230, 232, 234, 236) to avoid the failed link. After notification (402) of the failed link, a control facility (28) responds by creating (404) commands that compensate for the failed link. The control facility (28) sends (404) the commands to at least the node (150) that detected the failed link. If not already performed by the control facility (28), the node (150) then modifies (364, 366) its routing tables (220, 230, 232, 234, 236) so that data packets are not returned to their sending nodes, and to avoid the failed link.
