Abstract: In some embodiments, a device includes a first portion and a second portion. The first portion includes a rounded shape for introduction into an opening of a structure. The second portion includes a recess to receive a needle from an instrument. A retrieval mechanism retrieves the device after removal of the device from the instrument. The device is collapsible in the structure when removed from the instrument after insertion of the instrument and the device into the structure.

Abstract: Generally discussed herein are systems, apparatuses, and methods for cyber resiliency. An apparatus can include one or more memory devices including a plurality of instruction sets corresponding to respective application variants stored thereon, one of the application variants including an unmodified version of an application, and one of the application variants including a modified version of the application including the application altered to be resistant to a specified type of cyberattack, processing circuitry to execute the application variants based on a same input, and generate an output, and a monitor to compare output from each of the application variants, and in response to detecting that the output from an application variant of the application variants is not equal to the output from other application variants of the application variants executing a time delayed version of the application variants or restoring the application variants to a known good operating state.
