摘要: In a first embodiment, the invention relates to a method for nanoimprinting a pattern on a chalcogenide-glass substrate, comprising: (A) preparing a soft operational mold, the operational mold comprising an elastomeric matrix and a reinforcement, wherein the matrix is transparent to IR radiation, and the reinforcement is opaque to IR radiation, and the mold further includes a pattern to be replicated to the substrate; (B) placing the mold on a top surface of a chalcogenide-glass substrate to form a structure, and simultaneously applying (i) IR radiation to heat an area at a top surface of the substrate to a temperature T>Tg, where Tg is the glass transition temperature of chalcogenide-glass, and (ii) applying a controlled pressure on the mold to effect penetration to the top surface of the chalcogenide-glass substrate, thereby to replicate the pattern of the mold to the top surface of the substrate; and (C) separating the operational mold from the patterned substrate.

摘要: A method of monitoring network traffic in a communication network with a sentinel module to detect malicious activity is described. A gateway sentinel module receives network traffic directed through a gateway installed for a local distribution of the network, the gateway connecting the local distribution of the network to a core of the network. Malicious activity in the local distribution is detected based on a combination of: a local machine-learning model for identifying malicious activity in the local distribution, the local machine-learning model modelling network traffic from the local distribution; and a global machine-learning model. The global machine-learning model models network traffic from a plurality of local distributions of the network based training data from a plurality of local sentinel modules executed on a respective plurality of computing nodes. The computing nodes respectively receive network traffic from the plurality of location distributions. A corresponding device and system are also described.
