In sub-100-nm processes, many physical phenomena have become critical issues in the development of processes, devices, and circuits. To achieve reasonable compromise in ASIC design, device-and process-level characterization of physical designs is a fundamental requirement. In this paper, we address topics regarding "design for variability", which are(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)
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)
The nucleotide and amino acid sequences and the gene order of the mitochondrial genome are highly informative for studying phylogeny, population genetics, and phylogeography. This study determined the complete mitochondrial genome of the caprellid species Caprella scaura. The mitochondrial genome of C. scaura has a total length of 15,079 bp, with an AT(More)
The Caprellidea (Crustacea) have undergone an interesting morphological evolution from their ancestral gammarid-like form. Although most caprellid families have markedly reduced third and fourth pereopods (the walking thoracic limbs) and pleons (the posterior body parts), one family, Caprogammaridae, has developed pleon with swimming appendages (pleopods),(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)
