Abstract:
Disclosed are methods, kits, and compositions for fluorescent detection of single biomolecules, e.g. proteins, using highly sensitive fluorescent dyes and a flow cell with one interrogation space for irradiation by focused laser beam. The methods, kits, and compositions are useful in determining concentrations of molecules in samples to levels of 1 femtomolar, 1 attomolar, or lower. The methods, kits, and compositions also allow the determination of concentration over a wide range, e.g., 7-log range, without need for sample dilution.

Abstract:
Disclosed are systems and methods that enable an end user to control the parameters, behavior, and identity of network communications regardless of the limitations placed upon these controls by the end user's communications device or communications service provider. An intermediate media proxy resides on a telecommunications network and accepts inbound and outbound communications to and from a network communication device. The intermediate media proxy functions as an intermediary for network communications that occur between the network communications device and other network communications devices. In this manner, the intermediate media proxy can control various features of the communications independent of limitations enacted by the end user's communications device or communications service provider.
Abstract:
There is disclosed a method for determining the identity of one or more mutations or single nucleotide polymorphisms (SNPs) in a genome, comprising: a. contacting a sample genome, under conditions which permit template dependant oligonucleotide ligation, with a plurality of different oligonucleotide molecules which comprise (i) a first set of oligonucleotides each comprising a sequence of nucleotides that is complementary to a region on said genome that includes a known SNP site and which oligonucleotides are complementary to said region other than at a base at or near the 5' end of said oligonucleotides that is to be tested for complementarity to a base at the SNP site, each of said oligonucleotides comprising a unique label to identify both the base to be tested and the position of the SNP to be scored, (ii) a second set of oligonucleotides each comprising a sequence of nucleotides complementary to a region on said target genome for hybridisation with said target genome adjacent the 5' end of an oligonucleotide of said first oligonucleotide set, and a surface capture moiety, a phosphate moiety being located at any of either the 5' end of said first set of oligonucleotides or the 3' end of said second set of oligonucleotides, any resulting ligated oligonucleotide being immobilised on a solid support via the surface capture moiety, b. analysing said solid support for the identity of one or more of said unique labels and comparing the defined bases in any of said immobilised oligonucleotides to those of the reference one or more SNPs.
Abstract:
Granules of plastics material have grains of an inert mineral such as sand coated thereon to provide a habitat for microorganisms effective in waste water treatment, the granules having a predetermined particle size range, and the grains having a predetermined particle size range and being disposed at a predetermined packing density range on the granules. The particles have an average density of approximately 1.0 g/cc such that a proportion tend to float and a proportion tend to sink in the waste water. The particles are manufactured by contacting the granules of plastics material with a mixture of grains of the inert mineral and grains of a soluble substance such as salt, at an elevated temperature, to coat the granules with the mixture, and subsequently dissolving the soluble substance grains from the coating to provide the granules coated with the grains of inert mineral in the predetermined packing density range.
Abstract:
Cable, wire, optical fibre and other elongated objects may be encased in a tube (1d) which has a longitudinal axis and is made from an elongated strip of oriented crystalline thermoplastic polymer film, wherein the strip is memory-set into a split tubular shape. The split (13) may be parallel to the longitudinal axis or follow a helical path along the tube. Preferably, the strip is memory-set so portions adjacent its longitudinal edges overlap or are adapted to be interlocked (21, 22). After forming into tubular form, the split tube may be splayed open and wound up on a roll for easy transportation; the memory-set tube will re-form when the strip is unwound from the roll.
Abstract:
An improved air filter assembly for removing particles from air flow across the filter assembly utilizing a tackifier material in combination with an antibacterial substance. The air filter assembly comprises a peripheral frame adapted to be supported in communication with an intake opening in a residential return air duct; and a filter media mounted within the frame for removing particulate from air flowing from an upstream side of the filter assembly to a downstream side of the air filter assembly. The downstream side of the filter media comprises a layer of filter media treated with the tackifier material or a sticky oil and the antimicrobial substance.

Abstract:
Systems and methods are disclosed for a distributed computing infrastructure on a computer network comprising a plurality of computers. The distributed computing infrastructure (DCI) provides a software platform for creating, running, and managing distributed applications. DCI may include XML-capable software applications on a peer-to-peer network. DCI may include small, network-unaware applications called peerlets. DCI may include a system and method for creating complex distributed applications using pre-complied binaries. DCI may include a capability for multiple, independent collaborative sessions for distributed collaborative applications (e.g., chat, instant messaging, shared whiteboard, etc.). DCI may include systems and methods for reducing interactions between users and applications to archivable form and then playing back the interactions. DCI may include a system and method for automatic software retrieval on a peer-to-peer network.
Abstract:
A system and method are disclosed for using free storage capacity on a plurality of storage media as a virtual storage device on a computer network comprising a plurality of computers. A first portion of each storage medium stores data. To implement Virtual Network Attached Storage (VNAS), the respective “free” second portions of each storage medium are aggregated into a shared storage volume. Computers on the network may mount the shared storage volume at one of a plurality of mount points and may store data on the shared storage volume. VNAS may be implemented in a peer-to-peer manner whereby each computer acts as a server for the data stored on its part of the shared storage volume (i.e., the second portion of its storage media). VNAS may be used to implement a system and method for managing data fail-over.
