Methods and systems for obtaining an ocular aberration measurement of an eye of a patient are provided. The slug may include a similar depression such that the momentary connection between the wad, ball and slug may increase accuracy of the ammunition. The device also includes a tissue harvesting tip formed on the distal end of the shaft that is effective to excise a tissue sample when the shaft is moved to the distal position, and a cutting member that is coupled to the shaft at a position proximal to the tissue harvesting tip. Present storage virtualization systems are designed to work with NFS or CIFS systems, but not both. Appropriate algorithms facilitate a reconstruction of the inclusion region to determine structural and functional features of the inclusion. A minimal number of the CPU cores are allocated for processing the write operations, thereby increasing write latency.
