    In this article, I will investigate the concept of "othering" originally as part of a post-colonial theory. This concept is interested in many academic areas, including a literary study. In Kazuo Ishiguro's novel "Never Let Me Go" is about human clones raised for organs. The clones are excluded and discriminated to be "the…

  3. Eugenic World Building and Disability: The Strange World of Kazuo Ishiguro's Never Let Me Go.

    A crucial challenge for critical disability studies is developing an argument for why disabled people should inhabit our democratic, shared public sphere. The ideological and material separation of citizens into worthy and unworthy based on physiological variations imagined as immutable differences is what I call eugenic world building. It is justified by the idea that social improvement and freedom of choice require eliminating devalued human traits in the interest of reducing human suffering, increasing life quality, and building a more desirable citizenry. In this essay, I outline the logic of inclusive and eugenic world building, define and explain the role of the "normate" in eugenic logic, and provide a critical disability studies reading of the 2005 novel Never Let Me Go by Kazuo Ishiguro and its 2010 film adaptation. I argue that the ways of being in the world we think of as disabilities must be understood as the natural variations, abilities, and limitations inherent in human embodiment. When this happens, disability will be understood not as a problem to be eliminated but, rather, as a valid way of being in the world that must be accommodated through a sustaining and sustainable environment designed to afford access for a wide range of human variations.

  4. Health inequality and non-monotonicity of the health related social welfare function.

    In a recent paper in this journal Abasolo and Tsuchiya [Abasolo, I., Tsuchiya, A., 2004. Exploring social welfare functions and violation of monotonicity: an example from inequalities in health. Journal of Health Economics 23, 313-329] have strongly argued for the use of a non-monotonic health related social welfare function. This note discusses both the limitations of the measure proposed by Abasolo and Tsuchiya [Abasolo, I., Tsuchiya, A., 2004. Exploring social welfare functions and violation of monotonicity: an example from inequalities in health. Journal of Health Economics 23, 313-329] and the problems associated with their empirics. We are able to show how non-monotonicity may lead to paradoxical results and policies. Further we examine the empirics of Abasolo and Tsuchiya [Abasolo, I., Tsuchiya, A., 2004. Exploring social welfare functions and violation of monotonicity: an example from inequalities in health. Journal of Health Economics 23, 313-329] and provide an alternative explanation to the observed patterns in the data that do not violate monotonicity. Finally we briefly mention why the Atkinson-Sen framework may be more appropriate as a way forward.

    The affine scaling methods introduced by Dikin are generally considered the most efficient interior point algorithms from a computational point of view. However, it is actually an open question to know whether there is a polynomial affine scaling algorithm. This fact has motivated many investigations efforts and led to several convergence results. This is the case of the recently obtained results by Tsuchiya, Tseng and Luo and Tsuchiya and Muramatsu which, unlike the pioneering Dikin`s convergence result, do not require any non degeneracy assumption. This paper presents a new variant of the dual affine scaling algorithm for Linear Programming that,more » in a finite number of iterations, determines a primal-dual pair of optimal solutions. It is also shown the superlinear convergence of that variant without requiring any non degeneracy assumption.« less

  15. Equation of state of MgSiO3 post-perovskite

    NASA Astrophysics Data System (ADS)

    Sakai, T.; Dekura, H.; Hirao, N.

    2014-12-01

    Super-Earths which have a few times of the Earth's mass have been found in the extra solar system one after another. MgSiO3 post-perovskite (PPv) is an abundant silicate phase in such huge terrestrial planet's mantle (Tsuchiya and Tsuchiya, 2011). For preliminary internal structure estimation, the mass-radius relation was used (Zeng et al. 2013). Above 120 GPa, the mass-radius relation for MgSiO3 end-member is calculated from the equations of state (EoS) of PPv. Although the pressure condition of super-Earth's mantle reaches several hundreds GPa, the previously reported EoSs of PPv by the diamond anvil cell (DAC) experiment were limited up to around 150 GPa. These EoSs were extrapolated to multi-megabar condition for the calculation of the mass-radius relation. The large extrapolation yields uncertainty. The direct determination of the compression behavior of PPv at multi-megabar pressure is, therefore, important to understand the super-Earth's interior. Here we report PPv EoS up to 275 GPa based on DAC experiment and up to 1 TPa and 6000 K by ab initio calculation based on the density-functional theory in the same manner as Tsuchiya et al. (2004). Volume data were obtained up to 275 GPa by the DAC experiment and fitted to the third order Birch-Murnaghan EoS and the Vinet EoS. The experimental EoS agrees excellently with the calculated ab initio volume data within 0.5 % up to 500 GPa and 3000 K. The volume differences between the present result and those calculated by Caracas and Cohen (2008) were about 2.0-2.6 % in pressure range of 100-500 GPa at room temperature, while the volume differences were only 1 % with respect to the EoS based on shock experiment data (Mosenfelder et al. 2009) in the same pressure range. The present EoS shows internal consistency among DAC, shock and ab initio data up to 500 GPa within 1% in volume. Our new EoS provides more precise mass-radius relation for MgSiO3 end-member.

    It has been believed that water is carried into the deep Earth's interior by hydrous minerals such as the dense hydrous magnesium silicates (DHMSs) in the descending cold plate. A numbers of researches have been conducted so far about the high pressure behaviors of DHMSs. In recent years, we found new DHMS, phase H, at lower mantle pressure condition and the solid solution between phase H and d-AlOOH has been proposed as the most important carrier of water in the deepest part of Earth's mantle (Tsuchiya 2013 GRL, Nishi et al. 2014 Nature Geo., Ohira et al. 2014 EPSL). However, those hydrous minerals are actually not denser than surrounding (dry) mantle minerals (Tsuchiya and Mookherjee 2015 Scientific Reports) and the gravitational stability in deeper part of the Earth is questionable. Therefore, the effects of denser element such as Fe on the stability of DHMS are intimately connected to the ability of transportation of water into Earth's deep interiors. In order to assess the effect of Fe on the phase relation of phase H and d-AlOOH, we first investigated the high pressure behavior of the end-member composition of this system, the e-FeOOH. We have found the new high pressure transformation of FeOOH in the lower mantle conditions both theoretically and experimentally(Nishi et al. 2017 Nature). Here we show high pressure structures and the physical properties of FeOOH-AlOOH-phase H system using first principles calculation and discuss the possible geophysical implications of these phases.

  19. First principles study of iron-bearing MgO under ultrahigh pressure

    2017-12-01

    Understanding of minerals under ultrahigh pressure is essential to model interiors of super-Earths. Chemical compositions of the super-Earths are expected to be similar to those of the Earth. Computational studies on Mg-Si-O ternary systems under ultrahigh pressures, which are difficult to be achieved by diamond-anvil-cell experiments, have been intensively performed (e.g., [1] for MgO, [2,3] for SiO2, and [4,5] for MgSiO3). However, as far as we know, these studies have been restricted to pure Mg-Si-O systems. In the mantles of super-Earths, we expect that there should be impurities as in the Earth's mantle. Among candidates of impurities, iron is especially important to model interiors of super-Earths. Here, we investigate iron-bearing MgO under ultrahigh pressures by first principles. We clarify effects of iron on the phase transition of MgO and thermodynamic quantities by first principles. The role of the 3d electrons will be elucidated. [1] Z. Wu, R. M. Wentzcovitch, K.

    Early detection and appropriate treatment are the keys to tuberculosis control. In particular, providing appropriate treatment for tuberculosis in patients with HIV infection, rheumatoid arthritis (RA), chronic hepatic disease, or renal failure necessitating hemodialysis, and taking appropriate measures against adverse reactions to antituberculosis drugs are issues of critical importance. This mini-symposium, four experts explained the current status of "treatment of tuberculosis in patients with comorbidities" and proposed measures to address these problems. Dr. Aoki talked about "HIV infection complicated by tuberculosis." To the next, Dr. Yoshinaga gave a talk on "treatment of tuberculosis in RA patients receiving biological agents. Further, Dr. Sasaki lectured on "tuberculosis in patients with hepatic disease/impairment". Lastly, Dr. Takamori gave a lecture on "tuberculosis in patients with renal disease and those on hemodialysis. Tuberculosis patients often have some underlying diseases, and adverse reactions caused by antituberculosis drugs, such as hepatic and renal impairments, are matters of concern. I believe that this mini-symposium has provided useful information for physicians engaged in tuberculosis treatment and for many other healthcare professionals as well.

    This special issue contains peer-reviewed invited and contributed papers that were presented at The International Symposium on 'Future Trend in Soft Material Research with Advanced Light Source: Interdisciplinary of Bio- & Synthetic- Materials and Industrial Transferring', which was held in SPring-8, Japan, on September 1-3, 2010. Advanced light sources including neutron and synchrotron are becoming increasingly critical to the study of soft materials. This cutting-edge analytical tool is expected to lead to the creation of new materials with revolutionary properties and functions. At SPring-8, a new beam line dedicated to soft materials has now been launched as one of the most powerful X-rays for scattering and diffraction. Additionally, the next-generation light source, XFEL (X-ray Free Electron Laser), facilities are currently being developed in several locations. In the near future, femto-second and coherent X-ray sources will be available in soft material research and should reveal the various new aspects of advanced soft material research and technology. On the occasion of the third fiscal year of the CREST (project leader: Kazuo Sakurai) and ERATO (project leader: Atsushi Takahara) projects, we organized this international symposium in order to accelerate the discussion among global-level researchers working on next-generation synchrotron radiation science, biophysics and supramolecular science, modern surface science in soft materials, and industrial applications of neutron and synchrotron radiation sources. In this symposium 21 oral presentations, including 8 invited speakers from abroad, and 40 poster presentations from USA, France, Korea, Taiwan, and Japan were presented during the three day symposium. The symposium chairs reviewed the poster presentations by young scientists, and eight young researchers received the Award for Best Poster Presentation. We sincerely hope that these proceedings will be beneficial in future applications of advanced light

  2. Single-crystal structure determination of hydrous minerals and insights into a wet deep lower mantle

    NASA Astrophysics Data System (ADS)

    Zhang, L.; Yuan, H.; Meng, Y.; Popov, D.

    2017-12-01

    Water enters the Earth's interior through hydrated subducting slabs. How deep within the lower mantle (670-2900 km depth) can water be transported down and stored depends upon the availability of hydrous phases that is thermodynamically stable under the high P-T conditions and have a sufficiently high density to sink through the lower mantle. Phase H [MgSiH2O4] (1) and the δ-AlOOH (2) form solid solutions that are stable in the deep lower mantle (3), but the solid solution phase is 10% lighter than the corresponding lower mantle. Recent experimental discoveries of the pyrite (Py) structured FeO2 and FeOOH (4-6) suggest that these Fe-enriched phases can be transported to the deepest lower mantle owing to their high density. We have further discovered a very dense hydrous phase in (Fe,Al)OOH with a previously unknown hexagonal symmetry and this phase is stable relative to the Py-phase under extreme high P-T conditions in the deep lower mantle. Through in situ multigrain analysis (7) and single-crystal structure determination of the hydrous minerals at P-Tconditions of the deep lower mantle, we can obtain detailed structure information of the hydrous phases and therefore provide insights into the hydration mechanism in the deep lower mantle. These highly stable hydrous minerals extend the water cycle at least to the depth of 2900 km. 1. M. Nishi et al., Nature Geoscience 7, 224-227 (2014). 2. E. Ohtani, K. Litasov, A. Suzuki, T.

Bacteriol. 89:1335–1339. 1965.—Accumulation of large amounts of oxytetracycline occurred in Escherichia coli when the cells were incubated with high concentrations of oxytetracycline (100 to 400 μg/ml) in nutrient broth or in a medium containing glucose, K2HPO4, and MgSO4. In the absence of glucose or MgSO4, the accumulation was very small. The optimal pH for accumulation was about 6.5. Manganous ion could replace Mg++ in promoting the accumulation, though with decreased effectiveness. Malate and succinate were effective promoters of accumulation as well as glucose. Accumulation was inhibited at low temperatures or in the presence of metabolic inhibitors such as 2,4-dinitrophenol or sodium azide. Images PMID:14293007

  5. Exploration of ethical debates through Desai's The Inheritance of Loss, Ishiguro's Never Let Me Go and Smith's On Beauty.

    PubMed

    Misra, Jahnavi

    2014-09-01

    This essay examines debates over alternative ethical formulations that break from the Kantian model through contemporary fiction--Kiran Desai's The Inheritance of Loss (2006), Kazuo Ishiguro's Never Let Me Go (2005) and Zadie Smith's On Beauty (2005). The essay returns to the theory, the ethics of care, put forward by Carol Gilligan in In a Different Voice (1982), which has regained significance in the context of questions surrounding care in contemporary ethical thinking. While the three novels are concerned with ideas of care, beauty, justice and the tyranny of the mainstream, this essay examines particular themes in particular texts which suggest that ideas with otherwise subversive potential--like care or beauty or justice--lose their radicalism when they are incorporated within the impersonal, masculinist mainstream. Carol Gilligan's feminine ethics of care, with its respect for the particular, is not only still important as the stimulus to thinking about alternatives to overarching ethical discourses, but it could also re-confer these concepts of care, beauty and justice their revolutionary potential.

  6. Iconic memory is not a case of attention-free awareness.

    Mack, Arien; Erol, Muge; Clarke, Jason

    2015-05-01

    Whether or not awareness entails attention is a much debated question. Since iconic memory has been generally assumed to be attention-free, it has been considered an important piece of evidence that it does not (Koch & Tsuchiya, 2007). Therefore the question of the role of attention in iconic memory matters. Recent evidence (Persuh, Genzer, & Melara, 2012), suggests that iconic memory does depend on attention. Because of the centrality of iconic memory to this debate, we looked again at the role of attention in iconic memory using a standard whole versus partial report task of letters in a 3×2 matrix. We manipulated attention to the array by coupling it with a second task that was either easy or hard and by manipulating the probability of which task was to be performed on any given trial. When attention was maximally diverted from the matrix, participants were able to report less than a single item, confirming the prior results and supporting the conclusion that iconic memory entails attention. It is not an instance of attention-free awareness. Copyright © 2015 Elsevier Inc. All rights reserved.

When a polarized Fermi superfluid (N{sub {up_arrow}}>N{sub {down_arrow}}, where N{sub {sigma}} is the number of atoms in the hyperfine state described by pseudospin {sigma}={up_arrow},{down_arrow}) is loaded onto a ring-shaped trap with a weak potential barrier, some excess atoms ({Delta}N=N{sub {up_arrow}}-N{sub {down_arrow}}) are localized around the barrier. As shown in our previous paper [T. Kashimura, S. Tsuchiya, and Y. Ohashi, Phys. Rev. A 82, 033617 (2010)], this polarized potential barrier works as a {pi} junction in the sense that the superfluid order parameter changes its sign acrossmore » the barrier. Because of this, the phase of the superfluid order parameter outside the junction is shown to be twisted by {pi} along the ring, which naturally leads to a circulating supercurrent. While the ordinary supercurrent state is obtained as a metastable state, this spontaneous current state is shown to be more stable than the case with no current. Our results indicate that localized excess atoms would be useful for the manipulation of the superfluid order parameter in cold Fermi gases.« less

  8. Thermochronometry using red TL of quartz - a feasibility study from in-situ drill-hole samples

    Thermochronometry - the revelation of the temperature history of rock related to subsidence or uplift and erosion - relies on methods with closure temperatures >40-70 °C, such as (U-Th-Sm)/He or fission track analysis on apatite. These methods are applicable to young and tectonically active mountain ranges, but results of calculated mean denudation rates are too imprecise for older orogens. Several studies attested the quartz luminescence signal (325 °C TL peak, OSL fast component) isothermal decay at ambient temperatures as low as 56 °C (Prokein and Wagner, 1994; Herman et al., 2010; de Sarkar et al., 2013). The so far determined closure temperatures of the quartz luminescence thermochronometry system vary between ~35 °C for the OSL fast component (Herman et al., 2010) and ~70 °C for red thermoluminescence (RTL; Tsuchiya and Fujino, 2000) and are dependent on the cooling rate and the charge trap parameters. Although featuring a favourably low closure temperature - thus allowing to study the geologically most recent temperature history -, especially quartz OSL suffers from low dose saturation, limiting the application to highly erosive orogens. Saturation doses of RTL exceed those of OSL by a factor of 10 or more (Fattahi and Stokes, 2000), what opens up new perspectives in low-temperature thermochronometry. We here present experimental results on the general suitability of RTL for thermochronometry, obtained for samples from a drilling hole in the granitic basement of the Variscan Fichtelgebirge (Franconia, Germany). The samples allowed studying the RTL signal saturation level in-situ at different ambient temperatures up to ~55 °C (at 1831 m depth). Measurements confirmed depletion of the 325 °C RTL peak for ambient temperatures >25 °C, most probably for even lower temperatures. Irradiation experiments showed that the RTL signal is not in saturation for ambient temperatures >25 °C, even for this 'old' mountain range. We could further demonstrate that the

    In this paper, we asked to what extent the depth of interocular suppression engendered by continuous flash suppression (CFS) varies depending on spatiotemporal properties of the suppressed stimulus and CFS suppressor. An answer to this question could have implications for interpreting the results in which CFS influences the processing of different categories of stimuli to different extents. In a series of experiments, we measured the selectivity and depth of suppression (i.e., elevation in contrast detection thresholds) as a function of the visual features of the stimulus being suppressed and the stimulus evoking suppression, namely, the popular “Mondrian” CFS stimulus (N. Tsuchiya & C. Koch, 2005). First, we found that CFS differentially suppresses the spatial components of the suppressed stimulus: Observers' sensitivity for stimuli of relatively low spatial frequency or cardinally oriented features was more strongly impaired in comparison to high spatial frequency or obliquely oriented stimuli. Second, we discovered that this feature-selective bias primarily arises from the spatiotemporal structure of the CFS stimulus, particularly within information residing in the low spatial frequency range and within the smooth rather than abrupt luminance changes over time. These results imply that this CFS stimulus operates by selectively attenuating certain classes of low-level signals while leaving others to be potentially encoded during suppression. These findings underscore the importance of considering the contribution of low-level features in stimulus-driven effects that are reported under CFS. PMID:22408039

    Rat organic solute carrier protein 1 (rOscp1) was isolated from a rat testis cDNA library. Isolated rOscp1 cDNA consisted of 1089 base pairs that encoded a 363-amino acid protein, and the amino acid sequence was 88% and 93% identical to that of human OSCP1 (hOSCP1) and mouse Oscp1 (mOscp1), respectively. The message for rOscp1 is highly detected in rat testis. When expressed in X. oocytes, rOscp1 mediated the high affinity transport of p-aminohippurate (PAH) with a Km value of 15.7+/-1.9 microM, and rOscp1-mediated organic solutes were exhibited in time- and Na+-independent manners. rOscp1 also transported various structurally heterogenous compounds such as testosterone, dehydroepiandrosterone sulfate (DHEA-S), and taurocholate with some differences in substrate specificity compared with hOSCP1. Immunohistochemical analysis revealed that the rOscp1 protein is localized in the basal membrane side of Sertoli cells as observed in mouse testis [Kobayashi et al., 2007; Kobayashi, Y., Tsuchiya, A., Hayashi, T., Kohyama, N., Ohbayashi, M., Yamamoto, T., 2007. Isolation and characterization of polyspecific mouse organic solute carrier protein 1 (mOscp1). Drug Metabolism and Disposition 35 (7), 1239-1245]. Thus, the present results indicate that a newly isolated cDNA clone, rOscp1, is a polyspecific organic solute carrier protein with some differences in substrate specificity compared with human and mouse OSCP1.

  13. Electron Density Distribution Changes of Magnesiowüstite With Pressure

    Magnesiowüstite is one of the dominant minerals in the earth's lower mantle; its density and elasticity, substantially altered by its spin crossover, have direct consequence to interpreting deep-earth geophysical data. High-resolution single-crystal x-ray diffraction data can portray the 3-dimensional distribution of electron density through the Fourier transform of measured form factors. Here we present experimentally measured changes in electron density distribution of single-crystal (Mg.85,Fe.15)O as it goes through its iron(II) high-spin to low-spin electronic transition between about 40 and 60 GPa [Lin and Tsuchiya, 2008], in a diamond-anvil cell. As (Mg,Fe)O undergoes a pressure induced spin crossover (from high spin at low pressure to low spin at high pressure) due to overlap of its eg orbitals, the t2g orbitals become more pronounced to due a higher population of electrons, while the eg orbitals diminish. The spin splitting energy becomes increasingly unfavorable compared to the spin orbital pairing energy. By looking at the population of electrons at different directions in real space, we directly observe these changes in orbital occupation leading up to and during the spin crossover. Since high-Mg magnesiowüstite has a high symmetry structure at these pressure conditions, detecting relative changes in electron density distribution (comparing subsequent pressure steps) is feasible by collecting high resolution data offered by high-energy X rays and wide opening-angle diamond-anvil cells.

The osteogenic potential of these cells is of particular interest, given their recent usage for the closure of critical-sized bone defects and other nonhealing bone scenarios such as a nonunion. Recent literature suggests that inflammatory cytokines can significantly impact the osteogenic potential of these cells. A review of relevant, recent literature is presented regarding the impact of the inflammatory cascade on the osteogenic differentiation of these cells and how this varies across species.

  15. Autonomy and why you can "Never Let Me Go".

    PubMed

    Bowyer, Lynne

    2014-06-01

    Kazuo Ishiguro's book Never Let Me Go is a thoughtful and provocative exploration of what it means to be human. Drawing on insights from the hermeneutic-phenomenology of Martin Heidegger, I argue that the movement of Ishiguro's story can be understood in terms of actualising the human potential for autonomous action. Liberal theories take autonomy to be concerned with analytically and ethically isolatable social units directing their lives in accordance with self-interested preferences, arrived at by means of rational calculation. However, I argue that such theories are simplistic abstractions from our human-life world, distorting the fundamental embodied, embedded, and relational nature of autonomy. When we attend closely to our concrete, lived existence we see instead that autonomy is about responding appropriately to others with whom we share a world. As we follow the path of Ishiguro's central character Kathy H., we are shown how an awareness and acceptance of our existential finitude as precarious and fallible creatures is necessary for guiding such appropriate interactions. As Kathy grows and is affirmed into her life-world, which grounds and supports her Being, she moves from heteronomy to autonomy; from being moved by external laws to embodying those laws, thereby becoming autonomous. This is exemplified by her appropriation of the carer role, through which she responds in a fitting way to those with whom she shares her world, bearing the weight of and dwelling responsibly within our human condition.

    1,3,5-trioxane, often used as a solid fuel or source of formaldehyde, is a symmetric top of the C3v group. Although the microwave and low-resolution vibrational spectra have been studied extensively, only the νb{17} band near 1072 wn has been observed with rotational resolution. Here, we will present our studies of trioxane vapor from 1140-1220 wn, covering the νb{16} band at a resolution of approximately 30 MHz. Solid trioxane was heated, and the resulting vapor was entrained in a continuous supersonic expansion of argon. Continuous-wave cavity ringdown spectroscopy was then performed using a frequency-stabilized external cavity quantum cascade laser (EC-QCL) as the light source. In addition to providing new ro-vibrational transition frequencies of trioxane, the present work serves to validate our newly-developed EC-QCL spectrometer and will be used to evaluate the cooling performance of the sheath-flow supercritical fluid expansion source currently under development.

  17. Photodissociation resonances of jet-cooled NO2 at the dissociation threshold by CW-CRDS

    2015-05-01

    Around 398 nm, the jet-cooled-spectrum of NO2 exhibits a well identified dissociation threshold (D0). Combining the continuous-wave absorption-based cavity ringdown spectroscopy technique and laser induced fluorescence detection, an energy range of ˜25 cm-1 is analyzed at high resolution around D0. In addition to the usual molecular transitions to long-lived energy levels, ˜115 wider resonances are observed. The position, amplitude, and width of these resonances are determined. The resonance width spreads from ˜0.006 cm-1 (i.e., ˜450 ps) to ˜0.7 cm-1 (˜4 ps) with large fluctuations. The identification of at least two ranges of resonance width versus the excess energy can be associated with the opening of the dissociation channels NO 2 → NO (X 2 Π 1 / 2 , v = 0 , J = 1 / 2) + O (3 P 2) and NO 2 → NO (X 2 Π 1 / 2 , v = 0 , J = 3 / 2) + O (3 P 2). This analysis corroborates the existence of loose transition states close to the dissociation threshold as reported previously and in agreement with the phase space theory predictions as shown by Tsuchiya's group [Miyawaki et al., J. Chem. Phys. 99, 254-264 (1993)]. The data are analyzed in the light of previously reported frequency- and time-resolved data to provide a robust determination of averaged unimolecular dissociation rate coefficients. The density of reactant levels deduced (ρreac ˜ 11 levels/cm-1) is discussed versus the density of transitions, the density of resonances, and the density of vibronic levels.

    Subduction of Mid Ocean Ridge Basalt (MORB) transports crust elements to the deep Earth. Therefore, it is important to study MORB in order to understand geophysical processes in the mantle. The high Al2O3 content of the MORB gives rise to a new aluminous phase (NAL) that constitutes up to 25% of its composition [1]. Phase equilibrium study of MgAl2O4-CaAl2O4 generated the mineral CaMg2Al6O12 with hexagonal symmetry, which was proposed for the NAL phase [2,3]. The NAL chemical composition, however, shows significantly less calcium [1,4] and several compositions have been considered in previous studies of this phase [5,6]. Here we present an ab initio study of NAL phases at high temperatures with several possible compositions. We used the quasiharmonic approximation to address thermodynamic and thermoelastic properties and seismic velocities of this phase as function of composition. References[1] T. Irifune and A. E.

  19. Superadiabaticity of the lowermost part of the mantle thermally controlled by the post-perovskite phase transition

    Yuen, D. A.; Monnereau, M.

    2005-12-01

    There is increasing evidence of superadiabaticity in the lowermost portion of the mantle, from 500 to 700 km above the core-mantle boundary, from both seismology ( e.g Cammarano et al., 2005 ) and mineral physics ( e.g. da Silva et al, 2000 ). This may be caused by a blanketing effect due to a dense chemical layer ( e.g. Kellogg et al., 1999) or an accumulation of recycled crust ( Coltice and Ricard, 1999). The temperature-dependence of radiative thermal conductivity may also contribute to this superadiabatic state ( van den Berg et al., 2004 ). We have found also the post-perovskite( PPV) phase transition may also be a contributor to this phenomenon. From 3-D spherical-shell anelastic compressible convection including a deep phase change, the PPV, we have demonstrated that as long as the CMB temperature, T-cmb is higher than the temperature intercept of the PPV at the CMB pressure , T-i, the horizontally averaged temperature gradient in the the thermal boundary layer is equal to the Clapeyron slope of the PPV i.e. 6.25 K/km for a Clapeyron slope of 8 MPa/K, which corresponds to a core heat-flux of around 5 TW. This superadiabatic effect disappears, as soon as the CMB temperature becomes lower than T-i, due to secular cooling. This phenomenon is restricted to a range of temperature of above T-i. We have found that T-cmb can be as high as 4000 K for this superadiabatic condition to prevail. Such a phenomenon would prevent a double-crossing of the phase change by the horizontally averaged temperature profile, as proposed by Hernlund et al. ( 2005), at least in the range of the physical parameters of PPV transition , as measured by laboratory experiments and derived by ab initio calculations ( Tsuchiya et al., 2004 )

  20. Ab Initio Predictions of K, He and Ar Partitioning Between Silicate Melt and Liquid Iron Under High Pressure

    Element partitioning is an important property in recording geochemical processes during the core-mantle differentiation. However, experimental measurements of element partitioning coefficients under extreme temperature and pressure condition are still challenging. Theoretical modeling is also not easy, because it requires estimation of high temperature Gibbs free energy, which is not directly accessible by the standard molecular dynamics method. We recently developed an original technique to simulate Gibbs free energy based on the thermodynamics integration method[1]. We apply it to element partitioning of geochemical intriguing trace elements between molten silicate and liquid iron such as potassium, helium and argon as starting examples. Radiogenic potassium in the core can provide energy for Earth's magnetic field, convection in the mantle and outer core[2]. However, its partitioning behavior between silicate and iron remains unclear under high pressure[3,4]. Our calculations suggest that a clear positive temperature dependence of the partitioning coefficient but an insignificant pressure effect. Unlike sulfur and silicon, oxygen dissolved in the metals considerably enhances potassium solubility. Calculated electronic structures reveal alkali-metallic feature of potassium in liquid iron, favoring oxygen with strong electron affinity. Our results suggest that 40K could serve as a potential radiogenic heat source in the outer core if oxygen is the major light element therein.­­ We now further extend our technique to partitioning behaviors of other elements, helium and argon, to get insides into the `helium paradox' and `missing argon' problems.

  1. Spatial Frequency Tuning during the Conscious and Non-Conscious Perception of Emotional Facial Expressions – An Intracranial ERP Study

    Previous studies have shown that complex visual stimuli, such as emotional facial expressions, can influence brain activity independently of the observers’ awareness. Little is known yet, however, about the “informational correlates” of consciousness – i.e., which low-level information correlates with brain activation during conscious vs. non-conscious perception. Here, we investigated this question in the spatial frequency (SF) domain. We examined which SFs in disgusted and fearful faces modulate activation in the insula and amygdala over time and as a function of awareness, using a combination of intracranial event-related potentials (ERPs), SF Bubbles (Willenbockel et al., 2010a), and Continuous Flash Suppression (CFS; Tsuchiya and Koch, 2005). Patients implanted with electrodes for epilepsy monitoring viewed face photographs (13° × 7°) that were randomly SF filtered on a trial-by-trial basis. In the conscious condition, the faces were visible; in the non-conscious condition, they were rendered invisible using CFS. The data were analyzed by performing multiple linear regressions on the SF filters from each trial and the transformed ERP amplitudes across time. The resulting classification images suggest that many SFs are involved in the conscious and non-conscious perception of emotional expressions, with SFs between 6 and 10 cycles per face width being particularly important early on. The results also revealed qualitative differences between the awareness conditions for both regions. Non-conscious processing relied on low SFs more and was faster than conscious processing. Overall, our findings are consistent with the idea that different pathways are employed for the processing of emotional stimuli under different degrees of awareness. The present study represents a first step to mapping how SF information “flows” through the emotion-processing network with a high temporal resolution and to shedding light on the informational correlates of

  2. Vertical eddy diffusivity as a control parameter in the tropical Pacific

    2011-12-01

    Ocean models suffer from errors in the treatment of turbulent sub-grid-scale motions responsible for mixing and energy dissipation. Unrealistic small-scale physics in models can have large-scale consequences, such as biases in the upper ocean temperature, a symptom of poorly-simulated upwelling, currents and air-sea interactions. This is of special importance in the tropical Pacific Ocean (TP), which is home to energetic air-sea interactions that affect global climate. It has been shown in a number of studies that the simulated ENSO variability is highly dependent on the state of the ocean (e.g.: background mixing). Moreover, the magnitude of the vertical numerical diffusion is of primary importance in properly reproducing the Pacific equatorial thermocline. This work is part of a NASA-funded project to estimate the space- and time-varying ocean mixing coefficients in an eddy-permitting (1/3dgr) model of the TP to obtain an improved estimate of its time-varying circulation and its underlying dynamics. While an estimation procedure for the TP (26dgr S - 30dgr N) in underway using the MIT general circulation model, complementary adjoint-based sensitivity studies have been carried out for the starting ocean state from Forget (2010). This analysis aids the interpretation of the estimated mixing coefficients and possible error compensation. The focus of the sensitivity tests is the Equatorial Undercurrent and sub-thermocline jets (i.e., Tsuchiya Jets), which have been thought to have strong dependence on vertical diffusivity and should provide checks on the estimated mixing parameters. In order to build intuition for the vertical diffusivity adjoint results in the TP, adjoint and forward perturbed simulations were carried out for an idealized sharp thermocline in a rectangular domain.

    The background of the higher education of Dr. Michiharu Matsuoka shown on the official resume was disclosed by Dr. Kazuo Naito in 1986, but the courses of the elementary and secondary schools were not described in it. In regard to his lower educational courses, the author referred to the laws and regulations issued by the Ministry of Education of the Japan Government and the Yamaguchi Prefectural Office. Those were often revised with times. The author presumed the elementary school (Murozumi Primary School [the first established primary school at the birthplace; Murozumi, Hikari-City, Yamaguchi Prefecture]) and middle schools (Prefectural Yamaguchi Middle School and Yamaguchi High School) to which he had been admitted. These presumptions were made to explain his whole educational course without unreasonableness. After finishing the first school year of the Yamaguchi High School, he was transferred to the Preparatory Course of the Yamaguchi Higher School (Yamaguchi Kotô Chugakkô, Yoka), because of the amendment of the educational system. Then he was transferred to the Preparatory Course of the Daisan Higher School (Daisan Kotô Chugakkô, Yoka), and to the Preparatory Course of Daiichi Higher School (Daiichi Kotô Chugakkô, Yoka). After his graduation from the Regular Course of the Daiichi Higher School (Daiichi Kotô Chugakkô, Honka), he was admitted to the Medical College of the Imperial University from which he graduated in 1897. In addition, he was a medical student of the Graduate School of the Imperial University of Tokyo just before he left Japan for studying abroad. The whole academic carrier of Dr. Matsuoka is not only clearly clarified, but it is also indicated that he was one of the successful examples of the educational system proposed by Yamaguchi Prefecture in Meiji era which articulated the local primary and middle schools with the Imperial University of Tokyo.

Trends in Cognitive Sciences, 11, 16-22, 2007] and possibly even orthogonal processes [Lamme, V. A. F. Why visual attention and awareness are different. Trends in Cognitive Sciences, 7, 12-18, 2003]. Attention and consciousness converge when conscious visual percepts are attended and hence become available for conscious report. In such a view, a lack of reportability can have two causes: the absence of attention or the absence of a conscious percept. This raises an important question in the field of perceptual learning. It is known that learning can occur in the absence of reportability [Gutnisky, D. A., Hansen, B. J., Iliescu, B. F., & Dragoi, V. Attention alters visual plasticity during exposure-based learning. Current Biology, 19, 555-560, 2009; Seitz, A. R., Kim, D., & Watanabe, T. Rewards evoke learning of unconsciously processed visual stimuli in adult humans. Neuron, 61, 700-707, 2009; Seitz, A. R., & Watanabe, T. Is subliminal learning really passive? Nature, 422, 36, 2003; Watanabe, T., Náñez, J. E., & Sasaki, Y. Perceptual learning without perception. Nature, 413, 844-848, 2001], but it is unclear which of the two ingredients-consciousness or attention-is not necessary for learning. We presented textured figure-ground stimuli and manipulated reportability either by masking (which only interferes with consciousness) or with an inattention paradigm (which only interferes with attention). During the second session (24 hr later), learning was assessed neurally and behaviorally, via differences in figure-ground ERPs and via a detection task. Behavioral and neural learning effects were found for stimuli presented in the inattention paradigm and not for masked stimuli. Interestingly, the behavioral learning effect only became apparent when performance feedback was given on the task to measure learning

    Four plants, Cirsium arvense (creeping thistle), Equisetum arvense (field horsetail), Oxalis acetosella (wood sorrel) and Phragmites australis (common reed), which grew in an abandoned Sb-mining area in Pernek (Malé Karpaty Mts., Slovakia), were investigated for the yeast species. Yeasts were isolated from both the leaves of the plants and the soil adjacent to the plants. In total, 65 yeast cultures, belonging to 11 ascomycetous and 5 basidiomycetous yeast species, were isolated. The species most frequently isolated from both the soil and leaf samples were Trichosporon porosum, Galactomyces candidus and Candida solani, whereas Aureobasidium pullulans, Candida tsuchiyae and Sporidiobolus metaroseus were isolated exclusively from the plant leaves. All the yeast species isolated were tested for their tolerance to two heavy metals (Cd, Zn) and three metalloids (As, Sb and Si). The yeasts isolated from both the leaves and soils exhibited a high tolerance level to both As and Sb, present in elevated concentrations at the locality. Among the yeast species tested, Cryptococcus musci, a close relative to Cryptococcus humicola, was the species most tolerant to all the chemical elements tested, with the exception of Si. It grew in the presence of 200 mmol/L Zn, 200 mmol/L Cd, 60 mmol/L As and 50 mmol/L Sb, and therefore, it can be considered as a multi-tolerant species. Some of the yeast species were tolerant to the individual chemical elements. The yeast-like species Trichosporon laibachii exhibited the highest tolerance to Si of all yeasts tested, and Cryptococcus flavescens and Lindnera saturnus showed the same tolerance as Cryptococcus musci to Zn and As, respectively. The majority of the yeasts showed a notably low tolerance to Cd (not exceeded 0.5 mmol/L), which was present in small amounts in the soil. However, Candida solani, isolated from the soil, exhibited a higher tolerance to Cd (20 mmol/L) than to As (2 mmol/L).

  7. Determining the 630nm emission altitude using modelling and observations from a tristatic configuration of Fabry-Perot Interferometers and EISCAT radars.

    Anasuya Aruliah, a.aruliah@ucl.ac.uk University College London, London, United Kingdom Michael Kosch, m.kosch@lancaster.ac.uk Lancaster University, Lancaster, United Kingdom Tristatic team Anasuya Aruliah,Ho-Ching Iris Yiu,Ian McWhirter, Michael Kosch,Kazuo Shiokawa,Shin-ichiro Oyama,Satonori Nozawa,Vikki Howells,Ian McCrea During early February 2010 a tristatic FPI-EISCAT experiment was run in order to investigate the peak emission altitude of the 630nm airglow and auroral emission in the region of the auroral oval. Two UCL Fabry-Perot Interferometers and a new STEL FPI have been located close to the three EISCAT radars at Tromsø, Kiruna and Sodankylü. The radars were pointed a at a common volume seen by all three FPIs, on assuming a peak emission height of 235km. This altitude is generally assumed to be fairly steady for FPI studies probing the behaviour of the upper atmosphere, though the height is a little different at other latitudes. The smoothing effect of the large viscosity of the upper thermosphere is invoked as a reason why the actual altitude is not too important, and there has been little investigation of the appropriateness of this assumption. However, mesoscale variability in the ionosphere has now been identified as producing a similar quantity of heating as does steady state convection; and FPIs and the CHAMP satellite have shown mesoscale structure in the high-latitude thermosphere. This indicates a need to revisit old assumptions that were based on the premise of thermospheric variability being large-scale. The STEL FPI at Ramfjord has a fully variable pointing direction mechanism and was programmed to point rapidly at successive volumes that would overlap the UCL KEOPS/Kiruna FPI look direction if the emission volume was 195km, 215km, 235km and 255km. Cross-correlation of the temperatures and intensity measurements would then identify the peak emission height. The EISCAT radar provided ionospheric parameters to model the 630nm emission profile

    On-ground detections of Thunderstorm Radiation Bursts (TRB) which mainly consist of bremsstrahlung gamma rays with energy extending up to 20 MeV indicate powerful electron accelerations inside thunderclouds or along lightning discharge paths (e.g. Torii et al., 2002, Tsuchiya et al., 2007, Dwyer et al., 2004). In order to resolve time variation and structure of the electron accelerators, we have constructed a multi-point mapping observation network with the aim of tracing gamma rays from moving thunderclouds since 2015. In fiscal 2016, we developed low cost and small size detectors dedicated to our observation. The data acquisition system records energy and timing of individual gamma-ray photons by 4-ch and 50 MHz sampling electrical boards (9.5 cm x 9.5 cm), coupled with BGO scintillator crystals. The systems were installed in portable water-proof boxes. We operated 10 detectors in two areas (Ishikawa and Niigata) along the coast of Japan Sea from October 2016 to April 2017. During this period, detectors in Ishikawa detected in total 10 TRBs lasting for several minutes associated with passage of a thundercloud. Our previous single-site measurement at Niigata, has recorded 1.4 TRBs per year on average in 2006-2015. Therefore, our new multi-point observation detected 7 times as many events as the previous system. One of the TRB gamma-ray spectra was fitted well by a cutoff power-law model. We performed a Monte Carlo simulation, and revealed that this spectrum was explained as bremsstrahlung of a monochromatic 15 MeV electron beam generated at an altitude of 500 m. We also succeeded in tracing gamma rays from an identical moving thundercloud with two detectors, demonstrating performance of the multi-point observation. In addition, we detected "short TRBs" lasting for a few hundred milliseconds associated with lightning discharges from four independent detectors placed 500 m apart simultaneously, in January and February 2017 at Niigata. The results in 2016-2017 winter

Structure analyses of soft materials based on synchrotron radiation (SR) and neutron beam have been developed steadily. Small-angle scattering and wide-angle diffraction techniques clarified the higher-order structure as well as time dependence of structure development such as crystallization and microphase-separation. On the other hand, reflectivity, grazing-incidence scattering and diffraction techniques revealed the surface and interface structural features of soft materials. From the viewpoint of strong interests on the development of SR and neutron beam techniques for soft materials, the objective of this symposium is to provide an interdisciplinary forum for the discussion of recent advances in research, development, and applications of SR and neutron beams to soft matter science. In this symposium, 21 oral papers containing 16 invited papers and 14 poster papers from China, India, Korea, Taiwan, and Japan were presented during the three-day symposium. As a result of the review of poster and oral presentations of young scientists by symposium chairs, Dr Kummetha Raghunatha Reddy (Toyota Technological Institute) received the IUMRS-ICA 2008 Young Researcher Award. We are grateful to all invited speakers and many participants for valuable contributions and active discussions.

    The 12th IAEA Technical Meeting on Energetic Particles in Magnetic Confinement Systems took place in Austin, Texas (7–11 September 2011). This meeting was organized jointly with the 5th IAEA Technical Meeting on Theory of Plasma Instabilities (5–7 September 2011). The two meetings shared one day (7 September 2011) with presentations relevant to both groups. Some of the work reported at these meetings was then published in a special issue of Nuclear Fusion [Nucl. Fusion 52 (2012)]. Summaries of the Energetic Particle Conference presentations were given by Kazuo Toi and Boris Breizman. They respectively discussed the experimental and theoretical progress presentedmore » at the meeting. Highlights of this meeting include the tremendous progress that has been achieved in the development of diagnostics that enables the ‘viewing’ of internal fluctuations and allows comparison with theoretical predictions, as demonstrated, for example, in the talks of P. Lauber and M. Osakabe. The need and development of hardened diagnostics in the severe radiation environment, such as those that will exist in ITER, was discussed in the talks of V. Kiptily and V.A. Kazakhov. In theoretical studies, much of the effort is focused on nonlinear phenomena. For example, detailed comparison of theory and experiment on D-III-D on the n = 0 geodesic mode was reported in separate papers by R. Nazikian and G. Fu. A large number of theoretical papers were presented on wave chirping including a paper by B.N. Breizman, which notes that wave chirping from a single frequency may emanate continuously once marginal stability conditions have been established. Another area of wide interest was the detailed study of alpha orbits in a burning plasma, where losses can come from symmetry breaking due to finite coil number or magnetic field imperfections introduced by diagnostic or test modules. An important area of development, covered by M.A. Hole and D.A. Spong, is concerned with the self

    TIA of MgO with [100] oriented vertically, the MgO LPO model could explain the anisotropy above the discontinuity. On the other hand, we found that TIA of PPv[001] in the aggregates (PPv + MgO) can explain the anisotropy below the discontinuity. Recent deformation experiment [Miyagi et al., 2010] and theoretical calculation [Metsue and Tsuchiya, 2011] suggest that the deformation texture of PPv is dominated by the (001) slip plane under the lowermost mantle condition. This slip system can make the TIA of PPv with [001] oriented vertically under the stressed condition. Therefore, the TIA of PPv[001] could be a main cause of the anisotropy in the D" layer. The LPO pattern is very limited to explain the observation. The VSV < VSH anisotropy could be caused by horizontal shear in the lowermost mantle. Thus, the shear stress may exist even above D" layer.

    Jupiter's synchrotron radiation (JSR) is the emission from relativistic electrons in the strong magnetic field of the inner magnetosphere, and it is the most effective prove for remote sensing of Jupiter's radiation belt from the Earth. Although JSR has been thought to be stable for a long time, intensive observations for JSR have made after the collisions of comet P/SL9 to Jupiter in 1994, and these observations revealed short term variations of JSR on time scale of days to weeks. However, the mechanisms which cause the short term variations of total flux density and brightness distribution have not been revealed well. In order to reveal the mechanism of short term variations of JSR more precisely, we have made radio image analysis using the NRAO (National Radio Astronomy Observatory) archived data of the VLA [*]. Brice and McDonough [1973, Icarus] proposed a scenario for the short term variations: i.e, the solar UV/EUV heating for Jupiter's upper atmosphere drives neutral wind perturbations and then the induced dynamo electric field leads to enhancement of radial diffusion. It is also suggested that induced dynamo electric field produce dawn-dusk electric potential difference, which cause dawn-dusk asymmetry in electron spatial distribution and emission distribution. So far the following results have been indicated for the short term variations. Miyoshi et al. [1999, GRL] showed that a short term variation event at 2.3GHz is well correlate to solar UV/EUV flux variations. Tsuchiya et al. [2010, Adv. Geosci.] showed that JSR at 325MHz and 785MHz have short term variations. These JSR observations confirmed the existence of the short term variation which is caused by solar UV/EUV. However, the effect of solar UV/EUV heating on the spatial distribution of JSR has never been confirmed, so this study is the first attempt to confirm the solar UV/EUV effect on spatial distribution of JSR. We have selected the data observed from 28th Jan. to 5th Feb. 2000 at 327MHz

  5. Predictions of the shear response of (Mg,Fe)SiO3 post-perovskite

    Observation of seismic data put in forth evidence of a spatial anisotropy in the seismic wave velocities in the D'' layer, the lowermost part of the mantle. (Mg,Fe)SiO3 post-perovskite (PPv) is thought to be the most abundant phase in this part of the mantle, and this mineral exhibits a strong elastic anisotropy and may contribute significantly to the seismic anisotropy in the D'' layer. However, the seismic anisotropy cannot be expressed at the rock scale if the orientations of the grains are distributed randomly. Consequently, the formation of lattice preferred orientations with an anisotropic mechanism of plasticity, such as dislocation creep, can cause the seismic anisotropy in the D'' layer. Some experiments have been done on the plasticity of pure and Fe-bearing MgSiO3 post-perovskite and lead to textures of deformation dominated by the (100) and (110) slip planes (Merkel et al., 2007) and by the (001) slip plane (Miyagi et al., 2010). On the other hand, theoretical calculations on the dislocations mobility on pure MgSiO3 (Carrez et al., 2007; Metsue et al., 2009) suggested a texture dominated by the (010) slip plane. A first step to understanding the mechanisms of plasticity and, therefore, the shear wave splitting occurring in the deep Earth is to test the response of the PPv phase to a plastic shear in a geophysical relevant composition. In this study, we present new results from first-principles calculations on the shear response of pure and ferrous iron-bearing MgSiO3 PPv. The originality of this work is the use of internally consistent LSDA+U formalism to accurately describe the local interactions between the d-states of iron. About 8% of iron is incorporated in the high spin state as a Mg substitution defect, since several studies suggest that iron is in the high spin in the D'' layer pressure range (Stackhouse et al., 2006; Metsue and Tsuchiya, 2011). We also performed the calculations for incorporated iron in the low spin state if an eventual spin
