In accordance with exemplary implementations, application computation operations and communications between operations on a host processing platform may be adapted to conform to the memory capacity of a parallel accelerator. Computation operations may be split and scheduled such that the computation operations fit within the memory capacity of the accelerator. Further, the operations may be automatically adapted without any modification to the code of an application. In addition, data transfers between a host processing platform and the parallel accelerator may be minimized in accordance with exemplary aspects of the present principles to improve processing performance.

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.

Cloud infrastructure of a cloud service provider comprises a processing platform implementing a security policy enforcement framework. The security policy enforcement framework comprises a policy analyzer that is configured to identify at least one security policy associated with at least one tenant of the cloud service provider, to analyze the security policy against configuration information characterizing the cloud infrastructure of the cloud service provider, and to control execution of one or more applications of said at least one tenant within the cloud infrastructure in accordance with the security policy, based at least in part on one or more results of the analysis of the security policy. The security policy enforcement framework may be implemented in a platform-as-a-service (PaaS) layer of the cloud infrastructure, and may comprise a runtime controller, an operating system controller, a hypervisor controller and a PaaS controller.

Methods and systems for processing outbound fax messages in an efficient and scalable manner are provided. According to one embodiment, an Internet fax system receives a request to deliver a fax message. Source files representing content to be included as part of the fax message are stored to a shared storage area accessible by imaging systems and fax processing resources. An imaging system is selected to convert the source files into a digital representation suitable for faxing. 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.

Privacy-preserving stream analytics (personal data collection method, apparatus, and/or system) from an electronic (e.g., mobile) device providing communications, such as to a network (e.g., Internet). Data queries from a data analyst are received but not directly answered with a truthful query response. Truthful responses are privatized and anonymized based on a randomized response mechanism which releases privatized data and not the original answer. 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.

Routing data packet traffic in packet networks, expediting the flow of the data packets and reducing the effects of congestion at nodes is accomplished by capturing latency data for nodes for initial measurement times; and computing a least squares estimate of the delay as a recursive least-squares solution.

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.
