On the Ability of a CNN to Realize Image-to-Image Language Conversion

The purpose of this paper is to reveal the ability that Convolutional Neural Networks (CNN) have on the novel task of image-to-image language conversion. We propose a new network to tackle this task by converting images of Korean Hangul characters directly into images of the phonetic Latin character equivalent. The conversion rules between Hangul and the phonetic symbols are not explicitly provided. The results of the proposed network show that it is possible to perform image-to-image language conversion. Moreover, it shows that it can grasp the structural features of Hangul even from limited learning data. In addition, it introduces a new network to use when the input and output have significantly different features.Comment: Published at ICDAR 201

ケニア産キク科薬用植物Vernonia hindiiに含まれる生物活性物質

A novel stigmastane-type steroid glucoside glucoside has been isolated from the aerial parts of Vernonia hindii.The structure was elucidated by spectroscopic methods.The compound exhibitewd lettuce seedling growth inhibitory activity.熱帯・砂漠など特殊な環境に自生する植物には、生物活性2次代謝物質を含むものが多く、古くから民間伝承薬や天然殺虫剤として使用されてきた。しかし、まだ十分に調査・研究されていない植物も残されている。本研究では、ケニアに自生するキク科薬物植物のVernonia hindiiに含まれる活性物質の単離と構造解明を行い、その生物活性を調べた。植物生長制御試験を指標としてV . hindiiのメタノール抽出物を文画・精製した結果、新規の化学構造をもつ植物生長抑制物質を単離した。さらに、種々の分析機器を用いて化学構造を解析し、stigmastan型のステロイド配糖体であると決定した。この化合物は100μg / discでコントロールと比べ、24％まっでレタスの生長を抑制した

In-situ ice and meteorological observations in the southern Sea of Okhotsk in 2001 winter: ice structure, snow on ice, surface temperature, and optical environments

The 2001-ice season in the Sea of Okhotsk was characterized by extraordinarily developed ice extent. During the period February 17 to 21, we conducted in-situ observations in the southern ice area with the icebreaker \u27Soya\u27. In this paper, we show the observational results, concerning the core sampling of about 1.3 m-thick ice, snow sampling, surface temperature, and solar radiation under clear sky conditions. It is shown that (1) the sampled ice core is composed entirely of granular ice, (2) the 30 cm-thick snow pack overlying sea ice is composed mainly of depth hoar and significant vertical gradients of δ^O and temperature are found within the snow, probably associated with the depth hoar formation, (3) surface temperatures as low as about -30°C are detected on snow-covered sea ice floes at nighttime under almost clear and light breeze conditions, (4) from the estimation of the turbidity coefficient, the atmosphere over the ice-covered area is considered to be significantly clean. Furthermore, the NOAA/AVHRR satellite data are used to estimate the surface temperature distribution in the southern Sea of Okhotsk. It is shown that these data are useful for discriminating thick ice floes
