Abstract: Disclosed embodiments include apparatuses for and methods of separating tissue with opposing jaw members having distal ends that translate toward a surface of the tissue as the jaw members are rotated outwardly to maintain engagement with the tissue. In an illustrative embodiment, an apparatus includes jaw members rotatably coupled adjacent to their proximal ends. The jaw members define opposing outwardly-facing curved channels disposed between their proximal and distal ends that slidably engage a distal pin. A bracket defines a distal socket that receives the distal pin. As the jaw members are motivated in a distal direction relative to the bracket toward the distal pin, engagement of the distal pin with the outwardly-facing curved channels causes the jaw members to rotate to cause the distal ends of the jaw members move outwardly transversely to the distal direction while the distal ends translate in the distal direction.

Abstract: A method, a computer program product, and a computer system predictively compensate for expected audio communication issues. The method includes determining conditions of a first device associated with a user. The method includes determining, based on the conditions, a first signal strength to a first network that the first device is currently connected in which to perform a communication and a second signal strength to a second network that the first device is configured to utilize in performing the communication.

Abstract: A method to secure a production environment in a network begins by associating a set of resources into a simulated environment layer configured to simulate at least a portion of the production environment. A preferred approach to building the simulated environment layer utilizes generative adversarial network (GAN) machine learning modeling. Upon detecting a suspect user attempting to interact with the production environment, one or more requests received from the suspect user are routed to the simulated environment layer as opposed to the production environment. At least one behavior of the simulated environment layer is then modified as the suspect user interacts within the simulated environment layer. The modified behavior facilitates that an attack initiated by the suspect user can proceed. Information (such as the user's tactics, techniques and procedures (TPPs), or other Indicators of Compromise (IoCs) associated with the attack is captured for analysis and subsequent action.
