Disclosed is a method and system for optimizing a first set of rules enforced by a firewall on network traffic. Characteristics of the network traffic are examined and these characteristics are used to generate a second set of rules. The first set of rules may have a different order than the second set of rules.

A method for clustering together network IP addresses is disclosed. A number of IP addresses are received and processed to determine which IP addresses share a longest prefix matching. The longest prefix matching process is performed according to radix encoded trie which facilitates on-line clustering of the IP addresses. Client and/or server IP addresses may be clustered in accordance with the teachings herein.
摘要:
The present invention increases the efficiency of performing longest prefix matching operations by selecting a radix-encoded trie structure optimized with respect to memory cost. The structure is optimized by determining memory costs for retrie structures indexed on different numbers of high-order characters, and then selecting the structure corresponding to the lowest memory cost. The optimization improves performance in IP look-up operations as well as longest-prefix matching operations performed on general alphabets.

The present invention relates to methods for producing metal-coated palladium or palladium-alloy particles. The method includes contacting hydrogen-absorbed palladium or palladium-alloy particles with one or more metal salts to produce a sub-monoatomic or monoatomic metal- or metal-alloy coating on the surface of the hydrogen-absorbed palladium or palladium-alloy particles. The invention also relates to methods for producing catalysts and methods for producing electrical energy using the metal-coated palladium or palladium-alloy particles of the present invention.
摘要:
A system and method is disclosed for determining a level of similarity among more than one image. Anticipated spatial characteristics of an image are used for automatically identifying segments within the image and for identifying weights to be added to the color characteristics associated with the identified segments. To determine similarity, comparisons are made between weighted color characteristics of corresponding segments of different images. The identified segments have attributes such as size, position and number which are based on the anticipated spatial characteristics of the image. The anticipated spatial characteristics of the image include, among other things, differences in image characteristics that are anticipated at relative positions within the image. Additionally, a standard for representing image data including feature descriptors for color characteristics is disclosed, the color feature descriptor being divided into plural units corresponding to segments within the image identified based on anticipated spatial characteristics therefor.
摘要:
Anti-cytokine therapy has revolutionized immunological disease treatment, but is not always effective and subject to treatment resistance as the cytokine cascade is highly redundant and multiple cytokines are involved in inflammation. Targeting a critical common regulator of inflammatory effectors is desirable. Lipopolysaccharide (LPS)-responsive beige-like anchor (LRBA) is a master regulator of multiple genes important for inflammation. Subcellular localization shows that LRBA translocated to the nucleus upon LPS stimulation and colocalized with multiple proteins associated with the endosome membrane system, indicating a critical role in membrane/vesicle trafficking essential for deposition, secretion and signal transduction of immune effectors. Deregulation, deficiency, down-regulation and overexpression of LRBA causes defective trafficking and signaling of immune effector molecules, resulting in immunodeficiency and autoimmunity diseases associated with a broader spectrum of severe symptoms when compared to other CVID genes. Modulating LRBA through antibodies, dominant negative mutants, or small interference RNA can be used to treat inflammatory diseases.
摘要:
A minimum confidence level is applied to recognize a localizable wireless system debility from a debility which is invariant from place to place or which cannot be significantly distinguished from service performance levels of comparable mobile user terminals in the network as a whole. Reports received by the population of users of a service or product family are scored, aggregated, normalized, and averaged overall and for each geographic service area. A report is received from a particular end user and the customer operated wireless instrument and transformed into an individual user experience score over a length of time and breadth of locations. The reports provided by the population of users are transformed into a population experience score that reflects usage in the same time and locations reported from the wireless instrument of the particular end user. Various potential causations are considered and those which exceed a minimum level of confidence are presented.
摘要:
A system and method identify a set of rules for determining a commonality of attributes across different behavior changes for a network. The system performs the method by receiving a set of data correlating network triggers to performance changes of one or more network devices. The set of data further includes an indication of a sign of the performance change for each of the network devices based on the triggers. The method further includes extracting a set of rules relating to a set of relationships between the triggers and the performance changes. The rules identify a commonality of the performance changes for multiple network devices based on the triggers.
摘要:
A mobility management node and a method in a mobility management node for reducing signalling caused by changes of location of a radio terminal, which mobility management node is configured to be operatively comprised by a wireless communication system and to operatively manage the mobility of the radio terminal and to operatively communicate with a gateway node acting as an interface between the system and an external network. The method comprises obtaining initial position information; obtaining boundary information indicating a boundary area wherein at least one of a policy or a charging rule is to be applied for the radio terminal; obtaining current position information; determining whether the radio terminal is inside or outside the boundary area; providing mobility information when the radio terminal is outside the boundary area and not providing mobility information to the gateway node when the radio terminal is inside the boundary area.
摘要:
The present invention provides materials and methods for detecting, quantifying, and/or high-throughput-profiling microRNAs. Advantageously, the present invention is more sensitive and specific than other currently-available miRNA qPCR assays. In addition, the present invention is convenient, easy-to-perform, and cost-effective. In one embodiment, the present invention provides a universal primer for reverse transcription of all miRNAs, a universal reverse primer for PCR amplification reaction, and universal probes. In another embodiment, the present invention provides assays that allow simultaneous detection and/or quantification of a plurality of target miRNAs using a single reverse transcription reaction.
