No full textZorotypus impolitus Mashimo, Engel, Dallai, Beutel, & Machida, sp. n. (Figs. 3, 4, 8) Type series. Holotype, apteron male, MALAYSIA: Selangor, Ul Gombak (elevation ca. 200–400 m), 10 April 2011, coll. Y. Mashimo & R. Machida (UKM). Paratypes, 3 apteron males, 3 apteron females, 1 alate female, same data as holotype (SEHU, SMRC, UKM). Apteron and alate specimens were collected under the bark of rotting wood. Diagnosis. This species is similar to Z. sinensis and Z. medoensis but can be distinguished from them by the following: body size distinctly smaller, 2 mm vs. 3–4 mm; long stout bristles on ventral surface of metafemur, proximal 1 st and 3 rd bristles longer than others vs. more distad bristles shorter; male S 8 without posterior extension of posteromedial part; and in the shape of the male genitalia (cf. Hwang 1976: Figs. 3–6). Etymology. The specific epithet is based on the Latin impolitus, referring to the unpolished brown coloration of the body. Description. Apteron male. Body length ca. 2 mm (exclusive of antennae), color matte brown except membranous regions and yellowish white cercus; head subtriangular, slightly wider than pronotum, with whitish area in posterolateral corner; cephalic chaetotaxy as in Figure 3 A, curly setae grouped on vertex (likely associated with fontanelle gland as in males of some other species); compound eyes and ocelli absent; antennae 9 -segmented, distal three antennomeres paler (Fig. 8 A), antennomere I slightly curved outward, antennomere II faintly curved, short, about one-half length of antennomere III, antennomeres III–IX longer than wide, length subequal to that of antennomere I (Fig. 8 A); both mandibles with five apical teeth and well-developed molar region (Fig. 8 B, B’).

Alate. General features as in apterous form except as follows: unpolished, blackish brown coloration. Compound eyes and three black ocelli present. Mesonotum indistinctly divided into slightly pointed prescutum, large mesoscutum, and smaller mesoscutellum (Fig. 3 C). Wings as in Figs. 8 C and 8 C’.Published as part of Mashimo, Yuta, Yoshizawa, Kazunori, Engel, Michael S., Abd, Idris, Dallai, Romano, Beutel, Rolf G. & Machida, Ryuichiro, 2013, Zorotypus in Peninsular Malaysia (Zoraptera: Zorotypidae), with the description of three new species, pp. 498-514 in Zootaxa 3717 (4) on pages 507-511, DOI: 10.11646/zootaxa.3717.4.4, http://zenodo.org/record/21964

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;
Onion-like carbon-encapsulated Co, Ni, and Fe magnetic nanoparticles with low cytotoxicity synthesized by a pulsed plasma in a liquid
No full textWe synthesized onion-like carbon-encapsulated Co, Ni, and Fe (Co-C, Ni-C, and Fe-C) magnetic nanoparticles with low cytotoxicity using pulsed plasma in a liquid. The pulsed plasma is induced by a low-voltage spark discharge submerged in a dielectric liquid. The face-centered cubic Co and Ni, and body-centered cubic Fe core nanoparticles showed good crystalline structures with an average size between 20 and 30 nm were encapsulated in onion-like carbon coatings with a thickness of 2-10 nm. Vibrating-sample magnetometer measurements revealed the ferromagnetic properties of as-synthesized samples at room temperature (Co-C=360 Oe, Fe-C=380 Oe, and Ni-C=211 Oe). Raman-spectroscopy analysis found onion-like carbon shells composed of well-organized graphitic structures. Thermal gravimetric analysis showed a high ___________________

stability of the as-synthesized samples under thermal treatment and oxidation. Cytotoxicity measurements showed higher cancer cell viability than samples synthesized by different methods
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
