摘要:
Techniques and systems for providing optimization of traffic routing for data centers are disclosed herein. In some embodiments, a method may include identifying a plurality of available source sites and paths or routes between an online service provider (OSP) and a destination prefix. A traffic manager may measure a cost for each of the plurality of available paths. In some instances, the traffic manager may also measure a performance value for each of the available paths. The traffic manager may then select one of the available source sites and paths as a preferred source site and path that has a minimized cost for an instance of the performance value when compared to other paths of the plurality of available source sites and paths. In further embodiments, the traffic manager may rewrite a routing table and DNS mapping to implement the preferred source site and path as the default source site and path between the OSP and the destination prefix.

Dual-functional nonfouling surfaces and materials, methods for making dual-functional nonfouling surfaces and materials, and devices that include dual-functional nonfouling surfaces and materials. The dual-functional surfaces are nonfouling surfaces that resist non-specific protein adsorption and cell adhesion. The dual-functional surfaces and materials include covalently coupled biomolecules (e.g., target binding partners) that impart specific biological activity thereto. The surfaces and materials are useful in medical diagnostics, biomaterials and bioprocessing, tissue engineering, and drug delivery.

Described herein are technologies pertaining to matrix computation. A computer-executable algorithm that is configured to execute perform a sequence of computations over a matrix tile is received and translated into a global directed acyclic graph that includes vertices that perform a sequence of matrix computations and edges that represent data dependencies amongst vertices. A vertex in the global directed acyclic graph is represented by a local directed acyclic graph that includes vertices that perform a sequence of matrix computations at the block level, thereby facilitating pipelined, data-driven matrix computation.

Processes are described herein for preparing medical devices and other articles having a low-fouling surface on a substrate comprising a polymeric surface. The polymeric surface material may possess a range of polymeric backbones and substituents while providing the articles with a highly efficient, biocompatible, and non-fouling surface. The processes involve treating the substrate to reduce the concentration of chemical species on the surface of or in the substrate without altering the bulk physical properties of the device or article, and thereafter forming a grafted polymer layer on the treated substrate surface.

A power control method and device for mobile communication are disclosed. The power control method, performed by a mobile communication device including a controller, a radio frequency (RF) circuit and a baseband circuit, includes receiving, by the RF circuit, a first signal; determining, by the controller, when a second signal is come; turning off, by the controller, the RF circuit when the first signal is received and the second signal has not yet arrived; and processing, by the baseband circuit, the received first signal.

An enhancement to a web browser offers an extension mechanism for web applications to utilize client-side resources, thereby moving more extensibility and flexibility to the client-side. The web browser may expose some control interfaces to meet various requirements from web applications. Using the extension mechanism, the web applications are able to offload the cloud servers, function when offline, and improve performance. The extension mechanism also provides users with full control to the data passing through their web browsers.

Predicate checking in conjunction with distributed systems can enable an investigating user to check predicates in the context of instance states and/or distributed states of a distributed system. In an example embodiment, a method entails accepting distributed system simulation data and performing a simulation of a distributed system using the distributed system simulation data to create distributed system simulated states. At least a portion of the distributed system simulated states are exposed. The exposed portion of the distributed system simulated states is retrieved and stored as exposed states for the distributed system. The exposed states for the distributed system are compared to predicate states for the distributed system. If an inconsistency is detected between the exposed states and the predicate states based on the comparing, at least one alarm is issued.

The present invention discloses hydrocarbylidene nitrohydrozinecarboximidamides and the use thereof as well as a method for making the same. The structural general formula of the compounds are shown in formula I, wherein, R1 is C1-C10 saturated and/or unsaturated aliphatic hydrocarbonyl, benzyl, substituted benzyl, halogenated picolyl, halogenated thiazolyl methyl, tetrahydrofuryl methyl or oxazolyl methyl; R2 is hydrogen, C1-C5 saturated and/or unsaturated aliphatic hydrocarbonyl, phenyl, substituted phenyl, pyridyl or substituted pyridyl; R3 is hydrogen, C1-C10 saturated and/or unsaturated aliphatic hydrocarbonyl, furyl, phenyl, substituted phenyl, benzyl or substituted benzyl. The tests of insecticidal activity show that the hydrocarbylidene nitrohydrozinecarboximidamides shown by formula (I) have high preventive efficiency against insect pests of plants, such as aphid, plant hopper, cotton bollworm, asparagus caterpillar, and the like, and can be used as plant insecticides.
