Rice tungro disease (RTD) is a serious threat to rice production in South and Southeast Asia. RTD is caused by Rice tungro bacilliform virus (RTBV) and Rice tungro spherical virus (RTSV). Coinfection of RTSV and RTBV results in more severe symptoms in African rice Oryza glaberrima than in Asian rice O. sativa. In this study, we examined whether RTBV alone causes more severe symptoms in O. glaberrima than in O. sativa. The examination of 18 accessions of O. glaberrima for RTBV infection indicated that all the O. glaberrima accessions examined were susceptible to RTBV. The reactions to RTBV of three O. glaberrima accessions and two RTBV-susceptible varieties of O. sativa, Taichung Native 1 (TN1) and IR 64, were compared. RTBV accumulation varied depending on the plants and differences in RTBV accumulation were not evident between the two species. However, the O. glaberrima accessions were significantly more stunted by RTBV than IR 64 was. Discoloration of leaves by RTBV was evident in the O. glaberrima plants, but not in the O. sativa plants. Collectively, these results presumably indicated that O. glaberrima is generally more vulnerable to RTBV than O. sativa is.

Objectives Sound hypersensitivity is highly comorbid with migraine headaches. To elucidate the pathogenic mechanism of migraine attacks, we must first identify the types of everyday environmental sounds they perceive as unpleasant and clarify the acoustic properties of such sounds. This study aimed to clarify the true nature of "noise," i.e. everyday sounds perceived as unpleasant by migraineurs, by evaluating their subjective comfort/discomfort in response to several sounds commonly heard in everyday life. Methods Participants were presented with 20 environmental sounds they would likely hear daily. Subjects rated the pleasantness/unpleasantness of each stimulus using a nine-step scale. Patients We recruited 50 adults with migraine headaches (46 women, 4 men) and 50 healthy controls (35 women, 15 men). Results Migraineurs provided statistically significantly lower (more unpleasant) ratings to ambulance sirens, police car sirens, and railroad crossing bells than did controls. Our analysis also investigated the acoustic characteristics associated with higher rating gaps between the two groups. Greater divergence in ratings for the same stimulus was associated with less power (smaller amplitude envelope) and slower temporal variation in signals in the 400-Hz band. Conclusion We identified specific signal components associated with different subjective (un) pleasantness scores between migraineurs and healthy adults, which may lead to the elucidation of the pathogenic mechanism underlying migraine attacks triggered by sound.

Que Simone Weil soit l'une des premieres lectrices de Daisetz Suzuki en France est un fait peu connu. Cet article tentera de mettre en lumiere les caracteristiques de la lecture weilienne de Daisetz et l'influence que le bouddhisme zen a exercee sur Weil dans ses dernieres annees. Weil a lu en 1942 Essays in zen bouddhism 2^<nd> series de Daisetz, et a tout de suite copie tous les poemes bouddhistes dans ses essais. Elle en a ensuite traduit plusieurs en francais. Apres deux mois d'etude, elle a finalement ecrit ses reflexions sur les notions zen-bouddhistes et etabli des comparaisons avec la philosophie occidentale et les autres religions. Ainsi, son etude sur cette oeuvre a ete tres progressive, soigneuse et dense. Dans cette etude, Weil remarque particulierement la technique du <<Koan>>, et surtout sa force de destruction de la partie discursive et intelligente de Fame. Cette partie, d'apres Weil, n'est detruite que par une joie intense de pure contemplation (Mystere, experiences mystiques) ou par une douleur et un malheur extremes (Passion du Christ, Exercices Koan de bonzes). Apres cette destruction, dit-elle, les capacites intuitives sont acquises. Depuis 1938, Weil etudiait plusieurs religions, mythes et folklores et tentait de leur trouver un fondement commun. La rencontre avec Daisetz en 1942 a renforce sa conviction que c'est veritablement Dieu (personnel et aussi impersonnel) qui donne les souffrances et les malheurs aux hommes pour que cette destruction soit accomplie. Mais ii y a une grande divergence entre Weil et Daisetz. Alors que ce dernier souligne que cette destruction introduit le Satori (l'illumination) et amene les hommes au Jodo (la terre pure), la philosophe neglige ce theme. Tout en pensant que l'invocation au Bouddha est aussi efficace que l'invocation au Christ, Weil nie l'importance du Jodo. Cette lecture originale est fortement liee a l' indifference de Well envers la resurrection du Christ et la vie eternelle.

近年の情報コミュニケーション技術の発展により,われわれの社会的世界は劇的な変容を遂げている.また,これらの発展により,社会的世界についてのデジタルデータが急速に蓄積されつつある.デジタルデータを用いて社会現象のリアリティとメカニズムの解明を試みる新しい社会科学のことを計算社会科学と呼ぶ.本稿では計算社会科学の現状と課題について,特に社会学との関係を中心に概観する.計算社会科学に対して独自の定義を試みた後,計算社会科学がなぜ社会学にとって特別な意味をもつのかを説明する.また,計算社会科学のデータの新しさがどこにあるのかを明らかにし,計算社会科学の分析手法について解説する.最後に,計算社会科学の課題について述べる.
