Estimation of synchrotron-radiation background based on a real beam orbit

Some high-energy experiments have suffered from synchrotron-radiation background. As a measure, we have developed a new calculation method of synchrotron radiation based on a real beam orbit, aiming at quantitative estimations and the construction of a possible alarm system for the background. An explanation and a demonstration of our method are given.Comment: 6 pages, 7 figures, 2 table

PREPARATION OF 5H,7H-DIBENZ[c,e]OXEPIN-5-ONE DERIVATIVE THROUGH RECONSTRUCTION OF THE LACTONE RING

The systematic investigation of the efficient transformation of 6H-dibenzo[b,d]pyran-6-one into 5H,7H-dibenz[c,e]oxepin-5-one is described

REGIOSELECTIVITY OF THE PALLADIUM-MEDIATED INTRAMOLECULAR COUPLING REACTION OF HIGHLY OXYGENATED PHENYL BENZOATE DERIVATIVES AND APPLICATION TO THE SYNTHESIS OF ALTERTENUOL

The regioselectivity of the intramolecular biaryl coupling reaction of 3’,4’-dialkoxyphenyl 2,4-dimethoxybenzoates was investigated using a palladium reagent, and transition state models of the reaction are proposed. As an application of this study, a short-step synthesis of altertenuol is also performed

Knowledge Sharing from Domain-specific Documents

Recently, collaborative discussions based on the participant generated documents, e.g., customer questionnaires, aviation reports and medical records, are required in various fields such as marketing, transport facilities and medical treatment, in order to share useful knowledge which is crucial to maintain various kind of securities, e.g., avoiding air-traffic accidents and malpractice. We introduce several techniques in natural language processing for extracting information from such text data and verify the validity of such techniques by using aviation documents as an example. We automatically and statistically extract from the documents related words that have not only taxonomical relations like synonyms but also thematic (non-taxonomical) relations including causal and entailment relations. These related words are useful for sharing information among participants. Moreover, we acquire domain-specific terms and phrases from the documents in order to pick up and share important topics from such reports

The relationship between the Dark Triad traits and help-seeking attitude in high school students

Participants in previous studies on the Dark Triad of personality (Machiavellianism, Psychopathy, and Narcissism) have been mainly college students or older. In the present study, participants were 799 high school students, and the purpose was to identify the factor structure of the Dark Triad and examine differences according to sex, school year, and career direction. Additionally, we investigated the relationship between the Dark Triad and help-seeking attitudes. The results were in line with previous evidence, as the hierarchical factor structure of the Dark Triad was identified. Furthermore, negative influences of Machiavellianism and Psychopathy on help-seeking attitudes were found. On the other hand, there was a positive influence of Narcissism on help-seeking attitudes.Dark Triadとは，マキャベリアニズム，サイコパシー，自己愛傾向の3つの総称である。これまでのDark Triadに関する研究は，大学生以上を対象とした研究が主流である。本研究では，799名の高校生を対象に調査を実施し，Dark Triadの因子構造を確認するとともに，性別，学年，進路による差についても検討し，大学生以上を対象に行われた従来の研究の知見との比較を行うことを目的とした。また，合わせて援助要請との関連についても検討した。その結果，Dark Triadにおいては階層的な因子構造が高校生サンプルにおいても確認された。また，マキャベリアニズム，サイコパシーは援助要請に対してネガティブな関連がみられるのに対して，ナルシシズムはポジティブな関連がみられた

SYNTHESIS OF ZANTHOXYLINE AND ITS RELATED COMPOUNDS: REVISION OF THE REPORTED STRUCTURE

Benzo[c]phenanthridine alkaloid, zanthoxyline, was synthesized through an intramolecular biaryl coupling reaction of N-naphthylbenzamide derivative using a palladium reagent. Comparison of the NMR data for the synthetic product with that reported previously revealed that the proposed structure was incorrect. Synthesis of the related compounds suggested that the correct structure of zanthoxyline is the previously known decarine
