A digital-chip architecture for a 10(6)-synapse neural network is proposed. It runs on a 1.5-V dry cell to allow its use in portable equipment. An on-chip DRAM cell array stores synapse weights digitally to provide easy programmability and automatic refreshing. A pitch-matched interconnection and a combinational unit circuit for summing product allow a… (More)
SUMMARY We propose guidelines for LSI-chip design, taking the within-die variations into consideration, and for process quality improvement to suppress the variations. The auto-correlation length, λ, of device variation is shown to be a useful measure to treat the systematic variations in a chip. We may neglect the systematic variation in chips within the… (More)
Floating seaweeds play important ecological roles in offshore waters. Recently, large amounts of rafting seaweed have been observed in the East China Sea. In early spring, juveniles of commercially important fish such as yellowtail accompany these seaweed rafts. Because the spatial distributions of seaweed rafts in the spring are poorly understood, research… (More)

Twelve polymorphic microsatellite markers were isolated from the kelp Ecklonia cava Kjellman (Phaeophyceae, Laminariales). The applicability of these markers was confirmed by genotyping of 24 individuals from a natural population in Japan. All 12 loci were polymorphic, with the number of alleles ranging from 2 to 11 per locus. The range of expected… (More)
