Abstract:
A system and method integrates namespace management and storage management in a storage system environment. According to the invention, an integrated management framework provides an underlying infrastructure that supports various heterogenous storage access protocols within a single, logical namespace service. The logical namespace service is based on extensions to underlying storage management processes that cooperate to create the integrated management framework. Notably, these extensions are embodied as novel library functionality.
Abstract:
This invention relates to the identification of modified cytosine residues, such as 5-methylcytosine (5mC), 5-hydroxymethylcytosine (5hmC) and 5-formylcytosine (5fC) to be distinguished from cytosine (C) in a sample nucleotide sequence. Methods may comprise oxidising or reducing a first portion of polynucleotides which comprise the sample nucleotide sequence; treating the oxidised or reduced first portion and a second portion of polynucleotides with bisulfite; sequencing the polynucleotides in the first and second portions of the population following steps ii) and iii) to produce first and second nucleotide sequences, respectively and; identifying the residue in the first and second nucleotide sequences which corresponds to a cytosine residue in the sample nucleotide sequence. These methods may be useful, for example in the analysis of genomic DNA and/or of RNA.
Abstract:
A method, article of manufacture, and apparatus for protecting data. In some embodiments, this includes taking a snapshot of a physical volume with a native snapshot program, reading the snapshot block by block, creating a blank virtual container on a deduplicated virtual storage device, and populating the blank virtual container block by block based on reading the snapshot.
Abstract:
A method and apparatus for securing networks, focusing on application in Fibre Channel networks. A combination of unique security techniques are combined to provide overall network security. Responsibility for security in the network is assigned to one or more designated entities. The designated entities deploy management information throughout the network to enhance security by modifying the capabilities and operational permissions of the devices participating in the network. For example, through network control: logical management access or physical I/O access may be limited on a per device or per I/O basis; and all devices and ports in the network operate only with other approved devices and ports. These designated entities can better manage network security by exploiting a unique link authentication system as well as a unique push-model secure distributed time service. The link authentication involves a multi-phase nonce exchange exploiting various derivations of the nonce and other information such as hashes and encryptions. The push-model secure time distribution departs from the traditional Fibre Channel pull mode time distribution and provides for secure and reliable distributed time so that various security attacks may be defeated.
Abstract:
Techniques and systems are disclosed for detecting biomolecular interactions based on the motion of nanomotors. In one aspect, a method of detecting biomolecular interactions based on a motion of a nanomachine includes functionalizing a nanomachine with a capture probe adapted to interact with biological targets; and detecting a presence of the biological targets in an environment based on a motion of the nanomachine.
Abstract:
Provided herein is a method of determining a sequence of a target polynucleotide. The method can include the steps of a) providing a device including an array of relatively short polynucleotides and relatively long polynucleotides immobilised on a surface of a solid support, wherein the relatively long polynucleotides are fragments of the target polynucleotide and wherein the relatively long polynucleotides are separated by a distance of at least 10 nm, whereby parts of the relatively long polynucleotides that extend beyond the relatively short polynucleotides can be individually optically resolved; and b) determining the sequence of the target polynucleotide by detecting incorporation of nucleotides into strands complementary to the relatively long polynucleotide fragments using fluorescent labels associated with the incorporated nucleotides. Also provided is system for determining a sequence of a target polynucleotide. The system can include means for carrying out steps a) and b) of the above method.
Abstract:
The invention is directed to a method for analysing genome wide variation in an individual. The method comprises randomly fragmenting the individual's genome and generating sequence reads of multiple bases on all fragments of the individual's genome, aligning the sequence reads generated with a known genomic reference sequence, and analysing variations between the sequence reads derived from the individual's genome and the known genomic reference sequence.
Abstract:
Modified DNA polymerases have an affinity for DNA such that the polymerase has an ability to incorporate one or more nucleotides into a plurality of separate DNA templates in each reaction cycle. The polymerases are capable of forming an increased number of productive polymerase-DNA complexes in each reaction cycle. The modified polymerases may be used in a number of DNA sequencing applications, especially in the context of clustered arrays.
