Abstract: A computer implemented method is provided for clustering and visualization of an n-dimensional space in a Euclidean space. The method includes: collecting a plurality of multi-dimensional data sets; estimating a probability density function from each data set; approximating a dissimilarity between every pair of said probability density functions and recording every dissimilarity in a dissimilarity matrix; embedding the dissimilarity matrix into a Euclidean space having a dimensionality of three or less using a multi-dimensional scaling method; and graphically displaying relationships between data sets using data in the Euclidean space on a display of a computing device.

Abstract: The present invention is directed toward an apparatus for tactical ballistic protection for an individual. In particular, the present invention provides a portable device for dual use as a ballistic shield and a rifle mounting stand. The invention is comprised on a ballistic blanket attached to dual ballistic resistant transparent panes. The transparent panes are attached via a vertical hinge, at which the attachment point functions as a rifle mounting stand. The invention may be attached to existing structures via a combination of straps and hooks, or the device may be used free standing.

Abstract: Disclosed herein is an improved Bone Tendon Bone graft for use in orthopedic surgical procedures. Specifically exemplified herein is a Bone Tendon Bone graft comprising one or more bone blocks having a groove cut into the surface thereof, wherein said groove is sufficient to accommodate a fixation screw. Also disclosed is a porcine bone tendon bone graft for use in orthopedic procedures. Additionally, Also a method of harvesting grafts that has improved efficiency, increases the quantity of extracted tissue and minimizes time required by surgeon for implantation is disclosed.

Abstract: An exercise system is disclosed comprising an inflatable exercise ball having a bore extending therethrough and a resistance apparatus disposed within the lumen.

Abstract: A system, method and software product describe a customizable, index-based stock management methodology. This methodology provides for diversification and risk control of indexing combined with individual customization and active tax management.

Abstract: A dowel (300) is provided by obtaining a plug from the shaft (diaphysis) of various long bones. The dowel (300) has an intra-medullary canal (30) which can be packed with any of a variety of osteogenic materials. The dowel (300) has a cortical surface (10) into which an instrument attachment hole (15) may be machined and onto which an alignment mark (16) may be inscribed for proper orientation of the intra-medullary canal (30) or a driver slot (56) which may be used to assist in further machining of the bone dowel (300). The dowel (300) ha a chamfered insertion end and has improved biomechanical and vertebral fusion induction properties as compared to standard dowels known in the art. A threaded (31) or grooved (32) dowel (300) and an apparatus (400) for efficient production thereof are also provided.

Abstract: An interference screw is provided by machining a fragment of autograft or allograft cortical bone from a donor or from a recipient's amputated bone. The interference screw has a cortical surface into which a self-tapping thread is machined. The interference screw has a machined pointed, rounded or flush end and an opposite machined end which mates with a drive means, and has advantages over conventional interference screws known in the art in that subsequent to implantation, no residual hardware that must later be removed remains at the implant site.

Abstract: The bone grinder of this invention is capable of consistently producing ground bone particles of varying particle sizes, depending on the grinder head employed. The device provides the ability to easily interchange grinder heads according to the needs of a surgeon and the novel grinder head design optimizes the use of available bone stock by cutting the bone rather than crushing the bone.
