We investigated the morpho-physiological traits of rice (Oryza sativa L.) during germination and post-germination phases to explore avoidance hypoxic conditions. compared four lines selected for anaerobic (AG lines) with variety IR42. The capacity AG was higher than that percentages coleoptile elongation differed among lines; IR06F459 showed fastest rapid elongation. coleoptiles were significantly longer those α-amylase activity in germinating seeds At 2 days after sowing, sucrose glucose...

Early seedling growth, including emergence and vigor, is crucial in direct seeded rice. In this study, we examined the effects of gibberellic acid (GA3) ethephon (ET) on early growth rice, α-amylase activity soluble sugar content seeds. Rice seeds were treated with water (control), ET, GA3, or ET+ GA3 allowed to grow for 21 days. The results showed that ET synergistically improved lengths mesocotyl, coleoptile, mesocotyl+ first leaf. Moderate synergistic detected second third leaves....

This paper compares the prediction performance of document classification based on a variety feature selection measures. Empirical experiments were conducted for dataset re0 with 10 measures and SVM. It is confirmed that SVM-score proposed by Sakai Hirokawa (2012) outperforms standard small number features. In fact, 100 words are enough to get similar obtained all words. The reason good this capture not only characteristic positive samples but negative as well.

This study introduced a data screening method for comparing the reflectances in middle latitude forest regions collected by Geostationary Earth Observing (GEO) satellite and Low Orbit (LEO) satellite. attempts to reduce differences between relative azimuth angles of GEO LEO observations. The method, called azimuthal-angle matching (RAM), takes advantage high temporal resolution satellites, which enables collection wide range within day. performance RAM was evaluated using visible...

コムギ圃場におけるネズミムギ発生量とコムギ減収率との関係を迅速かつ簡易に把握するため，達観調査による簡易査定法を開発した。コムギとダイズを連作する静岡県袋井市豊住の水田転作団地を調査対象とし，2004年∼2007年のコムギ収穫時期に圃場別にネズミムギ発生量の達観調査を行った。達観調査による査定基準は「無」，「微」，「少」，「中」，「多」，「甚」の6段階とした。査定したランク別にコムギ収量，ネズミムギ個体数，全乾物重をコドラート（1m×1m）調査した。達観調査に基づく査定ランクごとにネズミムギの発生量（個体数と全乾物重）に明瞭な差があり，コムギの減収率を概ね適正に評価していた。コドラート内のネズミムギの個体数が多く，乾物重が大きいほど，コムギ精子実重の減収率が高く，その関係は方形双曲線モデルにより回帰できた（R2>0.6）。20%以上のコムギ減収が生じるネズミムギの密度は8∼12個体/m2以上であった。達観調査による簡易査定法は，地域レベルでの雑草発生量，コムギ減収量を迅速に推定する上で有効である。

We investigated the effect of poultry manure (PM) on occurrence and early growth Monochoria vaginalis in relation to soil solution electrical conductivity (SSEC). PM was applied at rates corresponding 0 g nitrogen (N) m−2 (PM-0), 1 N (PM-1), 3 (PM-3), 5 (PM-5). At 7 d post-seeding, sampled measure EC, also emergence M. were evaluated. The rate decreased with increasing application SSEC. SSEC significantly negatively correlated seedlings. average leaf number length did not differ between...

We previously worked on category classification problem of reuter 's newspaper article using SVM and feature selection. In the study, selection by SVM-score [Sakai, Hirokawa, 2012] showed high accuracy. It was also expected to be superior other standard indicators in case data is imbalanced. This study aimed show effectiveness machine learning with imbalanced data. For reuter's data, F-measure calculated experiment all 13 categories. As a result, shows f-measure precision. addition, we found...

Improving early seedling growth is crucial for direct-seeding rice cultivation.In this study, field and laboratory experiments were conducted to determine the effects of Plant Growth Regulators (PGRs) such as gibberellic acid (GA 3 ) ethephon (ET) on direct-seeded rice.Seeds treated with PGRs pre-germinated at 30°C in dark.For experiment, two Flooding Depth (FD) regimes established during period: 0 cm (drained condition) 2 (flooded condition).Treatment seeds ET or GA alone promoted organs...

This paper addresses a strategy learning problem in the RoboCupSoccer Small Size League (SSL). We propose novel method based on action sequences to cluster an opponent’s strategies online. Our proposed is composed of following three steps: (1) extracting typical actions from geometric data make sequences, (2) calculating dissimilarity and (3) clustering by using dissimilarity. can reduce amount used process; handling instead as data-set makes it easier search actions. As result, online...

Video captioning aims to generate textual descriptions according the video contents. The risk assessment of autonomous driving vehicles has become essential for an insurance company providing adequate coverage, in particular, emerging MaaS business. insurers need assess business plans with a fixed route by analyzing large number data, including videos recorded dash cameras and sensor signals. To make process more efficient, generating captions can provide concise information understand...

The combinatorial use of geostationary and polar-orbiting satellites is expected to provide a new approach Earth observation with wide range applications; however, differences in the conditions sensor specifications can introduce biases into outputs various satellites. These are also known depend on land cover type, this feature data requires thorough investigation. This study compared solar reflective bands measured by Advanced Himawari Imager (AHI) an established MODIS onboard Terra...

Water stress is a major limiting factor for plant growth and development. In this study, we investigated the effects of L-β-phenyllactic acid (LPA) on rice (Oryza sativa L.) seedlings under polyethylene glycol (PEG)-induced water deficit conditions. Seedlings were culture at 30 °C 14 days in pouches supplemented with 1/100-strength Murashige Skoog (MS) medium PEG presence or absence 100 mg L-1 LPA. As evidenced by height, LPA application enhanced seedling PEG-induced 13%. The shoot dry...

The rhythm of vocalizing a written language depends on merge process that combines meaningless linguistic units into meaningful lexical unit, word, or Bunsetsu in Japanese. However, most previous studies, was presented to the participants (word-by-word) with explicit inter-word (or inter-Bunsetsu) marks spacing. Therefore, it has been difficult conduct psychophysical assessment participants' own speed segmenting from unstructured when reading. Here, we hypothesized spontaneous reading...
