This work aimed to make the repetition of the experiment performed by Dosono et al , which studied how the current authentication interfaces pose significant burden to visually impaired persons. We revealed that previously found difficulties such as locating authentication area, verifying the success of authentication, and use of visual/voice… (More)
AgOTf-catalyzed intramolecular cyclization of phenoxyethynyl diols proceeded under mild conditions to afford the multisubstituted α,β-unsaturated-γ-lactones in 55-98% yields. This method was also applicable to the synthesis of α,β-unsaturated-δ-lactones. A similar cyclization proceeded when AgOTf was replaced with a stoichiometric amount of… (More)
Authors have developed the stepped multiple frequency Complementary Phase Code (CPC) radar system. The unique radar modulation/demodulation method can achieve both a high range resolution and a long-range detection performance with a narrow band receiver compared with the transmission bandwidth. In this paper, the experimental verification to compare the… (More)
An asymmetric synthesis of highly substituted indenes 3, bearing a quaternary stereogenic carbon center, has been developed via the central-axial-central chirality transfer from optically active propargyl alcohols 1. This transformation involves the addition/rearrangement of 1 and ynamides 2 to give tetra-substituted allenes 4 and further cyclization of 4.
Detection of quantitative trait loci (QTLs) is dependent on the materials used in the analysis, as different combinations of parental materials may lead to different outcomes in QTLs for the same trait. On the other hand, an extreme phenotype associated with a given trait implies the potential involvement of a particular allele in various allelic… (More)
Since Wireless Sensor Networks (WSNs) are regarded as large-scale distributed systems in nature, it is (i) difficult to implement their distributed low-level codes, (ii) hard to analyze their performance and (iii) almost impossible to operate a number of nodes manually. In this paper, we propose an integrated environment called D-sense to solve these… (More)
