Abstract: Systems and methods of monitoring and detecting suspicious activity in a virtual environment are provided. In one exemplary embodiment, a method performed by a first network node of monitoring and detecting suspicious activity in a virtual environment comprises sending, to a second network node that operates a virtual environment, an indication that user activity performed in the virtual environment that is associated with a certain user profile of a plurality of user profiles of the virtual environment is suspicious activity. Further, the user activity performed in the virtual environment that is associated with the certain user profile is enabled by a third network node. In addition, the suspicious activity is determined based on a relationship between the user activity performed in the virtual environment that is associated with the certain user profile and other user profiles, or an attribute of the certain user profile or the third network node.

Abstract: A method of making a structure having a patterned a base layer and useful in the fabrication of optical and electronic devices including bioelectronic devices includes, in one embodiment, the steps of: a) providing a layer of a radiation-sensitive resin; b) exposing the layer of radiation-sensitive resin to patterned radiation to form a base layer precursor having a first pattern of exposed radiation-sensitive resin and a second pattern of unexposed radiation-sensitive resin; c) providing a layer of fluoropolymer in a third pattern over the base layer precursor to form a first intermediate structure; d) treating the first intermediate structure to form a second intermediate structure; and e) selectively removing either the first or second pattern of resin by contacting the second intermediate structure with a resin developing agent, thereby forming the patterned base layer.

Abstract: A method of patterning a bioresorbable material includes providing a fluoropolymer layer in a first pattern over a layer of bioresorbable material. A patterned bioresorbable material is formed by selectively removing the bioresorbable material in areas not covered by the first pattern of fluoropolymer. The fluoropolymer layer may optionally be provided using a photosensitive fluoropolymer along with fluorinated solvents for coating and developing images. The disclosed methods may provide patterned bioresorbable materials having simple or complex shapes, coarse or fine features. In some embodiments, high volume manufacturing methods such as photolithography may be used. Flexible bioelectronic devices may be provided with patterned bioresorbable materials to aid in application into biological targets, but which later bioresorb thereby imparting higher flexibility to the bioelectronic device.
