Abstract: Techniques are disclosed for detecting risk via a server system that receives, based on user activity at a device, an indication of a trigger event corresponding to a potential electronic communication. After receiving the trigger event indication and prior to receiving an indication of initiation of the electronic communication, the system executes a set of computations for the communication, including performing a multi-hop query to a graph database storing a graphical representation of a plurality of communications and storing results of the execution. In response to initiation of the electronic communication, the system retrieves, using information corresponding to entities involved in the electronic communication, one or more portions of the results of executing the set of computations the database. The system determines, based on the retrieved results, whether to approve the electronic communication.

Abstract: Techniques are disclosed for implementing cross-zone communication for computing zones executing different coding protocols. A server computer system may receive, via a proxy layer of a first instance of an application executing within a first computing zone according to a first set of coding protocols, a request for a service executed via a second instance of the application in a second computing zone according to a second, different set of coding protocols. The system may alter, via a remote layer of the first instance, a set of data specified in the request to comply with the second, set of protocols. The system may transmit, via the remote layer of the first instance to a remote layer of the second instance, the altered set of data. The system may advantageously provide a simplified development interface allowing for both development and testing within a local environment without deployment of multiple different services.

Abstract: A method for operating a graph database, including receiving, by a computer system, a query to a particular graph database, the query identifying a plurality of vertices of the particular graph database. The method further includes performing, by the computer system, hash operations on two or more of the plurality of vertices to generate respective hash values and dividing, using the respective hash values, the query into a plurality of sub-queries, each corresponding to a subset of the plurality of vertices. The method also includes sending, by the computer system, ones of the plurality of sub-queries to a plurality of database repositories for the particular graph database.

Abstract: A wireless communication device and a method for adjusting a maximum number of accesses thereby are provided. The wireless communication device comprises a network speed providing module and a Wireless Local Area Network (WLAN) access number control module, wherein the network speed providing module is configured to provide a speed at a network side to a WLAN side; and the WLAN access number control module is configured to adjust a maximum number of accesses of a WLAN according to the speed at the network side provided by the network speed providing module. Through the disclosure, communication quality is ensured for an Internet user by adjusting a maximum number of user accesses of Wireless Fidelity (Wi-Fi); and when the network gets worse, the access of an excess user is not allowed or some users are removed according to a user rule.

Abstract: A method of fabricating Fiber Bragg gratings in a micro/nanofiber using ultrashort pulse irradiation, the method includes elongating and flame-brushing a single mode optical fiber to create a micro/nanofiber, and generating the ultrashort pulse irradiation to induce a plurality of refractive index changes at predetermined intervals within the micro/nanofiber, wherein the ultrashort pulse propagates through a focusing element and a diffractive element prior to propagating on the micro/nanofiber.
