A client-centric online navigation architecture that extracts relevant data from documents as a user is interacting with an information network, proposes related information services based on the types of data and data values extracted from the current viewed document, and presents a menu of related information. A browser plug-in extracts data from a web page as a user browses the Internet, and provides additional services to the web user as he browses. Data extraction wrappers created by a developer are distributed to the client machines. The wrapper supported information extraction process occurs apart from the content server, e.g., on the client machine or a proxy server. Extracted data can trigger the launching of services, called “hyperservices”, either on the local machine or remote machines.

A thermal cycle system and method suitable for mass production of DNA comprising a temperature control body having at least two sectors. Each sector has at least one heater, cooler, or other means for changing temperature. A path traverses the sectors in a cyclical fashion. In use, a piece of tubing or other means for conveying is placed along the path and a reaction mixture is pumped or otherwise moved along the path such that the reaction mixture is repetitively heated or cooled to varying temperatures as the reaction mixture cyclically traverses the sectors. The reaction mixture thereby reacts to form a product. In particular, polymerase chain reaction reactants may continuously be pumped through the tubing to amplify DNA. The temperature control body is preferably a single aluminum cylinder with a grooved channel circling around its exterior surface, and preferably has wedge-shaped or pie-shaped sectors separated by a thermal barrier.

The system provides, for storage in a block at the blockchain address, the digital signature. The system transmits the session identifier to the vehicle. The system transfers the firmware update file to the vehicle. The vehicle verifies the firmware update file using the digital signature retrieved from the block at the blockchain address, a second hash value of the firmware update file received from the data processing system, and the session identifier received from the data processing system.

Building binary packages for software products, particularly large-scale software products, is a highly computation intensive process. Thus, it is desirable to distribute the workload over a large number of computing nodes so as to have the build process complete in an optimal period of time. One environment providing compute resources that can be utilized for a highly available and dynamically scalable distributed build process is an elastic compute cloud. In such an environment, virtual machines can be instantiated and destroyed as the resource requirements of the build process dictate. This has the advantage that dedicated hardware is unneeded, and excess capacity on the hardware employed can be employed for other computation tasks when the build process is idle. Presented herein are systems, methods and computer storage media for distributing a highly available and scalable build service, suitable for use in an elastic compute environment or other distributed environment.

Anonymously transmitting randomized responses from the data owner to data aggregator using shares, each share of which is individually transmitted to an independent aggregator, which is configured for independently and asynchronously process each share, and sharing results with one another to arrive at a query response over an aggregate number of data owners.

The invention discloses a detection method for APTs (Advanced Persistent Threat) based on instruction monitoring. The method is characterized in that identification for virtual machine execution behaviors on an Hypervisor level is realized through an ExKVM and a virtual machine introspection library LibVMI, monitoring outside a virtual machine for an operating state of a malicious code in the virtual machine is realized and vulnerability exploitation attacks are discovered by use of a dynamic offline taint analysis method; monitoring for a user-layer API and kernel-layer API execution is carried out without an invasion by use of a #BP address injection method outside the virtual machine; and tracking for kernel stack allocation is realized through the injection of the kernel memory allocation function and the kernel module structure operating function of Windows. The offline taints are analyzed and the malicious behaviors are discovered through tracking and recording write, exchange and branch instructions between a memory and a register during the malicious code execution. According to the invention, the vulnerability exploitation during the APT attack can be monitored effectively and the detection rate of malicious samples is improved.

A method of separating metallic semiconducting carbon nanotubes includes providing a source of a mixture of semiconducting and metallic carbon nanotubes in a carrier liquid with one of the semiconducting and metallic carbon nanotubes being functionalized to carry a charge. The mixture is pressurized to cause a liquid jet of the mixture to be emitted through a nozzle. A drop formation mechanism modulates the liquid jet to form from the jet first and second drops traveling along a path. An electric field modulating device, positioned relative to the jet, produces first and second electric fields. A deflection device applies the first electric field as the first drop is formed to concentrate the functionalized carbon nanotubes in the first drop and applies the second electric field as the second drop is formed. The deflection device causes the first or second drop to begin traveling along another path.

Cell free nucleic acids from a test sample obtained from an individual are analyzed to identify possible fusion events. Cell free nucleic acids are sequenced and processed to generate fragments. Fragments are decomposed into kmers and the kmers are either analyzed de novo or compared to targeted nucleic acid sequences that are known to be associated with fusion gene pairs of interest. Thus, kmers that may have originated from a fusion event can be identified. These kmers are consolidated to generate gene ranges from various genes that match sequences in the fragment. A candidate fusion event can be called given the spanning of one or more gene ranges across the fragment.

A work request identifying the selected imaging system is stored on a centralized work queue within a database. The imaging systems poll the centralized work queue to retrieve pending work requests. Responsive to identifying the work request, the selected imaging system converts the source files, associates the resulting digital representation with an outbound fax job and causes the fax message to be delivered by submitting the outbound fax job to a fax modem.

Digital image acquisition device such as CCD / CMOS sensors often introduces random temporal noise into digital video sequences. Temporal noise generally carries high frequency components in both the spatial and temporal domains and is also random in nature. Because of these properties, they are generally very expensive to encode and would substantially degrade coding efficiency. It is therefore important to eliminate or suppress such temporal noise in video inputs prior to encoding. The present invention provides a methodology to achieve such a goal in a highly cost-effective manner where coding performance, latency, computational cost, and memory requirements are optimized. This methodology can be efficiently implemented as part of digital video compression algorithm and scales nicely for various bitrates.
