INFLUENCE OF VOLTAGE FLUCTIONS ON GYROTRON EFFICIENCY AND STABILITY

Influence of power supply voltage instability on gyrotron operation regime is investigated. Dependence of efficiency versus variations of external parameters is given and conditions of oscillations cutoff are determined. It is shown that positive voltage fluctuations result in sharp falling efficiency and failure of self-oscillations and the steadiest gyrotrons are those with short cavities and the large raito of transverse electron speed to longitudinal one around 1.5-2. Comparison of theoretical and experimental results is given.research repor

Description of a New Species of the Genus Euconnus (Coleoptera: Scydmaenidae) from Niigata Pref., Honshu, Japan

A new species, Euconnus (Euconophron) matsunoyamensis sp. nov., is described from Niigata Pref., Honshu, Japan. As a result of the discovery of that species, the number of Japanese species of the genus Euconnus becomes twelve.departmental bulletin pape

<i>Prdm9</i> ZF domains identified in equid species.

<p>Each ZF domain is color/letter coded and amino acid variation is indicated at positions −5, −2, −1, 3, and 6 (grey open boxes). ZF domains under the dotted lines are those only identified in equine hybrids but not in equid species. The seven amino acids linker is designated by grey bars and Cys₂His₂ residues by red letters.</p

デューイによる哲学の構想の批判的継承に向けて

2018-03-31Although many scholars take up Dewey’s works today, his meta-philosophical vision remains unclear. Scholars too often assume that Dewey’s philosophy can be summarized by one of its canonical aspects, such as his aesthetic, social or ethical theory. Given the pluralism that Dewey consistently advocated for, it is highly unlikely that he was seeking for a totalizing ideal. However, it is also true that he did continue to argue for the need for a common direction for future thinkers to follow. This paper is a speculative attempt to clarify this common direction. This paper methodologically makes use of Art as Experience, Dewey’s aesthetic theory, to envision philosophy as a mode of art. This approach allows one to see philosophy as a cultural practice with certain generic traits rather than a professional field with a fixed set of problems. I begin the discussion by pointing out that, philosophy, in Dewey’s view, is motivated by a sense of responsibility to decipher the consequences of human conduct. The thinker’s task is to analyze those consequences and their conditions. The sense of responsibility leads Dewey to examine the philosophical tradition and assess the limits of past ideas. This is necessary because, while the intellectual heritage continues to be a resource for present-day thinkers, its ideas begin to fail to meet the needs of newly emerging situations. Thus, philosophy, as a mode of art, is a continued attempt to reconstruct its heritage to revitalize its effectiveness in responsible human conduct.departmental bulletin pape

Diploid structure of <i>Prdm9</i> ZF domains in equids.

<p>Number and sequence of ZF domains are depicted, with individual’s gender shown. Color/letter coded ZF domains correspond to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0061746#pone-0061746-g002" target="_blank">Figure 2</a>. Lineage-specific ZF domains are mapped on the phylogeny of equids according to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0061746#pone.0061746-Henry1" target="_blank">[33]</a>. Domestic horse individuals showed the same <i>Prdm9</i> sequence for the last exon, thus only one sequence is depicted. The onager <i>Prdm9</i> sequence obtained from cDNA is designated by an asterisk.</p

Alignment of the domestic horse <i>Prdm9</i> ZF domains.

<p>The sequence validated as <i>Prdm9</i> in the domestic horse (bold) was blasted against the horse genome using NCBI, UCSC and Ensemble browsers. Amino acid variation of the sequenced domestic horse is highlighted by blue open boxes. Linkers between ZF domains are indicated by grey bars, the beginning of ZF domains by dotted lines, stop codons by asterisks, and Cys₂His₂ residues by red letters.</p
