Traditionally, for diagnosing patellar dislocation, clinicians make manual geometric measurements on computerized tomography (CT) images taken in the knee area, which is often complex and error-prone. erefore, we develop a prototype CAD system for automatic measurement and diagnosis. We firstly segment the patella and the femur regions on the CT images and then measure two geometric quantities, patellar tilt angle (PTA), and patellar lateral shift (PLS) automatically on the segmentation results, which are finally used to assist in diagnoses. e proposed quantities are proved valid and the proposed algorithms are proved effective by experiments.

We constructed a fusion protein ZZ-EGFP by fusing the ZZ domains of staphylococcal protein A (SpA) and enhanced green fluorescent protein (EGFP). ZZ-EGFP was secreted in the yeast, Pichia pastoris, with a hexahistidine tag. Its expression level was determined by measuring the fluorescence of EGFP. When the recombinant yeast cells in shake-flasks were induced with 0.5% methanol for 96 h, a maximum yield of 115 mg ZZ-EGFP/l was obtained. The resulting ZZ-EGFP fusion protein retained immunoglobulin G (IgG)-binding capacity and EGFP fluorescence. ZZ-EGFP was then used in immunofluorescence assays for detecting antinuclear antibodies (ANA); it produced a good signal that was comparable in its brightness and fluorescence pattern to that generated with fluorescein isothiocyanate (FITC)-labelled anti-human IgG. Thus, ZZ-EGFP showed great potential in immunological applications due to its ability to bind to various IgG from different animal sources.

An algorithm for computing + over a finite field (2 ) is presented using the properties of the irreducible all one polynomial of degree . Based on the algorithm, a parallel-in parallel-out systolic multiplier is proposed. The architecture of the multiplier is very simple, regular, modular, and exhibits very low latency and propagation delay. Therefore, it is suitable for very large scale integration implementation of cryptosystems.Index Terms-All one polynomial (AOP), finite field, latency, systolic multiplier.
