Abstract: A method and system for determining interaction sites between biosequences is described herein. A dataset of contact data for a plurality of biomolecule pairs is obtained to account their frequency of occurrence. Statistical weights are obtained for each frequency of occurrence. A statistical vector space (SRV) is decomposed through principal component decomposition. The r-vectors of the SRV are re-projected back to a new SRV with a new set of SR coordinates. A feature vector is generated and inputted into a predictor for outputting a likelihood of an interaction site. A method and system for determining significant attribute-value associations (AVAs) from relational datasets is also described. A frequency of occurrence of attribute value pairs and statistical weights may be obtained for each frequency of occurrence. Principal component decomposition and re-projection of AVA vectors may also be performed. The disentangle SR of AVAs could be used to identify AVA related to subgroups/classes.

Abstract: The invention is directed to a pill cutter that has a protected cutting edge. The pill cutter includes a guard, a base, and a cover. The components are arranged such that the guard slides over the cutting edge when the pill cutter is in an open position and the guard exposes the cutting edge when the pill cutter is in a closed position. The invention is also directed at a method for assembling the pill cutter and a method of using the pill cutter to cut a pill or tablet.
