OBJECTIVE This study aims to investigate the biomechanical effect of posterior cruciate ligament (PCL) rupture on lateral meniscus. METHOD The stresses of anterior horn, caudomedial part and posterior horn of lateral meniscus in cadaveric knees were recorded when the knee joints were loaded 200 to 1000 N at 0, 30, 60 and 90° of flexion. Twelve knees were(More)
BACKGROUND AND OBJECTIVES Deproteinization is an indispensable process for the elimination of antigenicity in xenograft bones. However, the hydrogen peroxide (H2O2) deproteinized xenograft, which is commonly used to repair bone defect, exhibits limited osteoinduction activity. The present study was designed to develop a new method for deproteinization and(More)
We construct new randomized algorithms to find the exact solutions to the shortest and closest vector problems (SVP and CVP) in Euclidean norm (2) for integral lattices. Not only the minimal 2-norm of non-zero lattice vectors in SVP and the minimal 2-distance in CVP, but also how many lattice vectors reach those minimums can be simultaneously computed by(More)
We construct an innovative SVP(CVP) solver for ideal lattices in case of any relative extension of number fields L/K of degree n where L is real(contained in R). The solver, by exploiting the relationships between the so-called local and global number fields, reduces solving SVP(CVP) of the input ideal A in field L to solving a set of (at most n) SVP(CVP)(More)
