Matsushita Carbon Resistors as Thermometers for Use at Low Temperatures and in High Fields (Physics)
No full textapplication/pdfA survey has been made of the properties of 1/8W composite resistors made by the Matsushita Electric Ind. Co. Ltd. to determine whether they might be suitable as secondary thermometers in the low-temperature region. From the measurements of resistance vs temperature, between 105℃ and 40mK, it is confirmed that the grade ERC-18SGJ resistors in various nominal room-temperature resistance values from 20 to 510Ω are suitable in very low-temperature work, and that resistors in the nominal resistance range 20-100Ω are the most suitable for work down to several tens of mK. An advantage of Matsushita resistors as thermometers in the low-temperature region is that they are available in 1/8W size, and we can choose their nominal resistances from 10Ω to several hundreds of ohms in steps of a few ohms. The magnetoresistance of Matsushita resistors having nominal resistances of 30 to 510Ω has been measured in fields up to about 80kG at temperatures between ～4.2 and ～1.5 K. It is shown that the percentage change in resistance due to the application of magnetic field as a function of temperature and field can be described approximately by the equation 100 ΔR/R=(C_1H^2+C_2H)/(1+C_3H^2)T^, where R is the resistance in zero field, ΔR the change in resistance when a field H is applied, and T the temperature. C_ are adjustable temperature-dependent parameters determined from the experimental data.紀要類(bulletin)123925 bytesdepartmental bulletin pape

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Pelevin’s Trinity in the novel “t”: author – protagonist – reader
No full textThe article attempts to interpret Pelevin's artistic strategy in the novel "T" by exploring its subject organization and addressing the key problems of the author, the protagonist, and the reader as they are seen by the researcher. The article analyzes the peculiarities of constructing the narrative reality in the novel "T", and goes on to discuss Pelevin's philosophic models of the development of the humankind, and the emergence of his new anthropology
Measuring industry-science links through inventor-author relations: A profiling method
No full textIn this pilot study we examine the performance of text-based profiling in recovering a set of validated inventor-author links. In a first step we match patents and publications solely based on their similarity in content. Next, we compare inventor and author names on the highest ranked matches for the occurrence of name matches. Finally, we compare these candidate matches with the names listed in a validated set of inventor-author names. Our text-based profile methodology performs significantly better than a random matching of patents and publications, suggesting that text-based profiling is a valuable complementary tool to the name searches used in previous studies.innovation; industry-science links; text-based profiling;

Tsuyuki leg.; 1 male, Shihtyuto, Lenai, Nantou County, Taiwan, 16. VI, 2002. Notes. This species was described under the genus Mesoereis by Matsushita (1933) based on a male specimen from Taiwan together with M. koshunensis which is the type species of Mesoereis. However, the external features of this species are very similar to Paragolsinda fruhstorferi or P. tonkinensis. Additionally, the endophallic structures of this species are very similar to P. t o n k i n e n s i s. For these reasons, this species should belong to the genus Paragolsinda. This species can be easily distinguished from other congeners by the following features: elytra with basal bosses rather low and round, punctures distributed throughout though becoming shallower and sparser apicad; lateral lobe of tegmen without distinct ridge near base.Published as part of Yamasako, Junsuke & Ohbayashi, Nobuo, 2011, Review of the genus Paragolsinda Breuning, 1956 (Coleoptera, Cerambycidae, Lamiinae, Mesosini), with reconsideration of the endophallic terminology, pp. 35-50 in Zootaxa 2882 on pages 44-46, DOI: 10.5281/zenodo.27757
Wave turbulence of a rotating array of quantized vortices in the T → 0 temperature limit
No full textThe dynamics of quantized vortices in the zero temperature limit is currently of great interest, particularly in the case of the Fermi superfluid He-B. Here we study wave turbulence, generated by the librating motion of a rotating cylindrical container filled with He-B, in the limit of vanishing viscous forces at temperatures . The polarization of the quantized vortices with respect to the axis of rotation is measured using non-invasive NMR techniques. We observe a decrease of the polarization when the librating motion is started, and a two-stage relaxation process when the modulation of the rotation velocity is stopped. The first relaxation process is associated with the dissipation of large-scale flow stored in inertial waves and the solid body rotation of the vortex array. From the decay of these energy reservoirs we determine the rate of energy dissipation of large-scale flow. The later second process is related to the relaxation of Kelvin waves on individual vortices. This process is monitored by the recovery of the polarization. The existence of a Kelvin wave cascade at the lowest temperatures is currently a central open question. We supply some evidence for the cascade
