This paper describes a timing analysis system (ACTAS: ACcurate Timing Analysis System). This system analyzes the logical behaviors of VLSI. It verifies timings at flip-flops and detects timing errors. Then, it calculates path delays of the partial combinational circuits generating the errors. If they do not satisfy timing constraints, the system detects(More)
BACKGROUND Total hip arthroplasty (THA) is a challenging surgical procedure that can be used to treat severely dislocated hips. There are few reports regarding cemented THAs involving subtrochanteric shortening osteotomy (SSO), even though cemented THAs provide great advantages because the femur is generally hypoplastic with a narrow, deformed canal.

We propose Landmark-Conscious Voice Navigation as one type of a pedestrian navigation system, which navigate users by only voice guidance. It is necessary to standardize data model in order to use this system widely. In a previous paper[1], we constructed a basic voice navigation system, which uses Open Street Map based data model. In this paper, at first,(More)
BACKGROUND We have developed crosslinked salmon-derived atelocollagen sponge, which has a denaturation temperature of 47 degrees Celsius. The purpose of this study is to evaluate the fundamental in vivo efficacy of the osteogenic protein (OP) -1 containing salmon-derived collagen sponge disc (SCS) on cartilage regeneration, using a rabbit model. METHODS A(More)
We examined the effect of 1-amino-3,5-dimethyladamantane (memantine) and (+)-5-methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine (MK-801) on the inhibition of [(3)H]MK-801 binding to crude synaptic membranes of rat forebrains in the absence or presence of Ca(2+). Ca(2+) decreased the potency of memantine to inhibit [(3)H]MK-801 binding. The effect(More)
It has been shown that end-to-side coaptation and nerve bypass grafting, which are essentially two sequential end-to-side coaptations, induce axonal outgrowth in peripheral nerve injuries. However, it is unknown whether the axons regenerated after end-to-side coaptation originate by collateral sprouting at the suture site or by elongation from the spinal(More)
