For each of the groups, the image for which the calculated spatial distance is the shortest and the radiographic interpretation information associated with the image is stored as a representative image of that group.

Abstract: A multiple inspection avoidance (MIA) technique is implemented in a virtualized environment. Preferably, the technique is implemented in a packet processing unit (PPU) and takes advantage of a protection scope determined in an automated manner. The protection scope may be MAC-based. The MIA technique ensures that the same packet is not inspected more than once by a same packet processing unit (PPU), and that the same packet is not inspected more than once by different PPUs. According to this disclosure, when a PPU implementing MIA receives a packet, it uses the protection scope to determine whether it needs to process the packet. Preferably, the determination of whether to process the packet depends on the source and destination addresses in the packet, whether those addresses are being protected by the PPU that receives the packet, the direction of the packet flow, and optionally one or more packet processing rules.

Abstract: A tapered fin field effect transistor can be employed to provide enhanced electrostatic control of the channel. A stack of a semiconductor fin and a dielectric fin cap having substantially vertical sidewall surfaces is formed on an insulator layer. The sidewall surfaces of the semiconductor fin are passivated by an etch residue material from the dielectric fin cap with a tapered thickness profile such that the thickness of the etch residue material decreased with distance from the dielectric fin cap. An etch including an isotropic etch component is employed to remove the etch residue material and to physically expose lower portions of sidewalls of the semiconductor fin. The etch laterally etches the semiconductor fin and forms a tapered region at a bottom portion. The reduced lateral width of the bottom portion of the semiconductor fin allows greater control of the channel for a fin field effect transistor.

Abstract: Embodiments described herein provide approaches for user access control to a secured application. Specifically, a custom authentication tool is configured to intercept a request from a user for access to a secured application and override one or more default requirements (e.g., application pre-registration, for accessing the application). That is, when credentials of the user are received at the authentication tool, they are verified against data within a user directory to generate a user profile, which is then provided to the secured application to satisfy the requirements for granting access to the user. As such, the secured application's requirements are met, yet users do not have to manually pre-register to obtain access because the registration is performed in the background by the authentication tool.
