Abstract

The Internet enables us to freely access music as recorded sound and even music scores. For the visually impaired, music scores must be transcribed from computer-based musical formats to Braille music notation. This paper proposes a transcription system from the MusicXML format to Braille music notation using a structural model of Braille music notation. The resultant Braille scores inspected by volunteer transcribers are up to the international standard. Using this simple and efficient transcription system, it should be possible to provide Braille music scores via the Internet to the visually impaired.

Abstract

Advanced satellite-based frequency transfers by TWCP and IPPP have been performed between NICT and KRISS. We confirm that the disagreement between them is less than 1x10^{-16} at an averaging time of several days. Additionally, an intercontinental frequency ratio measurement of Sr and Yb optical lattice clocks was directly performed by TWCP. We achieved an uncertainty at the mid-10^{-16} level after a total measurement time of 12 hours. The frequency ratio was consistent with the recently reported values within the uncertainty., Comment: 9 pages, 5 figures

Abstract

We have demonstrated a direct frequency comparison between two $^{87}{\rm Sr}$ lattice clocks operated in intercontinentally separated laboratories in real time. Two-way satellite time and frequency transfer technique based on the carrier phase was employed for a direct comparison with a baseline of 9 000 km between Japan and Germany. A clock comparison was achieved for 83 640 s resulting in a fractional difference of $(1.1\pm1.6) \times 10^{-15}$, where the statistical part is the biggest contribution to the uncertainty. This measurement directly confirms the agreement of the two optical clocks on an intercontinental scale.

Abstract

In this paper we report that carrier-phase two-way satellite time and frequency transfer (TWSTFT) was successfully demonstrated over a very long baseline of 9,000 km, established between the National Institute of Information and Communications Technology (NICT) and the Physikalisch-Technische Bundesanstalt (PTB). We verified that the carrier-phase TWSTFT (TWCP) result agreed with those obtained by conventional TWSTFT and GPS carrier-phase (GPSCP) techniques. Moreover, a much improved short-term instability for frequency transfer of $2\times10^{-13}$ at 1 s was achieved, which is at the same level as previously confirmed over a shorter baseline within Japan. The precision achieved was so high that the effects of ionospheric delay became significant which are ignored in conventional TWSTFT even over a long link. We compensated for these effects using ionospheric delays computed from regional vertical total electron content maps. The agreement between the TWCP and GPSCP results was improved because of this compensation.

27. Wolbachia and nuclear-nuclear interactions contribute to reproductive incompatibility in the spider mite Panonychus mori (Acari: Tetranychidae)

Abstract

The relationship between Wolbachia infection and reproductive incompatibility among populations of Panonychus mori is examined. Wolbachia infection caused incompatibility between uninfected females and infected males or between females and males harboring different Wolbachia strains whereas nuclear-nuclear interactions resulted in bidirectional incompatibility in 99 combinations of interpopulation crosses.

34. Vertical transmission of Wolbachia in Tetranychus kanzawai Kishida and Panonychus mori Yokoyama (Acari: Tetranychidae)

Abstract

The Wolbachia infection is maternally transmitted in a population of Tetranychus kanzawai, in which infected females produce infected offspring regardless of the infection status of the mating partners. However, in a population of Panonychus mori the infection frequency increases with each generation. The Wolbachia infection is vertically transmitted only by females.
