description: In a previous paper we explicitly constructed a mapping that leads Dirac spinor fields to the dual-helicity eigenspinors of the charge conjugation operator (ELKO spinor fields). ELKO spinor fields are prime candidates for describing dark matter, and belong to a wider class of spinor fields, the so-called flagpole spinor fields, corresponding to the class-(5), according to Lounesto spinor field classification, based on the relations and values taken by their associated bilinear covariants. Such a mapping between Dirac and ELKO spinor fields was obtained in an attempt to extend the Standard Model in order to encompass dark matter. Now we prove that such a mapping, analogous to the instanton Hopf fibration map $S^3... S^7\to S^4$, prevents ELKO to describe the instanton, giving a suitable physical interpretation to ELKO. We review ELKO spinor fields as type-(5) spinor fields under the Lounesto spinor field classification, explicitly computing the associated bilinear covariants. This paper is also devoted to investigate some formal aspects of the flag-dipole spinor fields, which correspond to the class-(4) under the Lounesto spinor field classification. In addition, we prove that type-(4) spinor fields (corresponding to flag-dipoles) and ELKO spinor fields (corresponding to flagpoles) can also be entirely described in terms of the Majorana and Weyl spinor fields. After all, by choosing a projection endomorphism of the spacetime algebra Cl(1,3) it is shown how to obtain ELKO, flagpole, Majorana and Weyl spinor fields, respectively corresponding to type-(5) and -(6) spinor fields, uniquely from limiting cases of a type-(4) (flag-dipole) spinor field, in a similar result obtained by Lounesto.

description: The comparison of specific interplanetary conditions for 798 magnetic storms with Dst < -50 nT for the period 1976-2000 was made on the basis of the OMNI archive data.We categorized various large-scale types of solar wind as interplanetary drivers of storms: corotating interaction region (CIR), Sheath, interplanetary CME (ICME) including magnetic cloud (MC) and Ejecta, separately MC and Ejecta, and "Indeterminate" type. The data processing was carried out by the method of double superposed epoch analysis which uses two reference times (onset of storm and the minimum Dst index) and make a re-scaling of main phase of storm a such way that after this transformation all storms have equal durations of main phase in new time reference frame. This method reproduced some well-known results and allowed us to obtain some new results. Specifically, obtained results demonstrate high importance of Sheath in generation of magnetic storms as well as a significant differences in properties of MC and Ejecta and in their geoeffectiveness.

Henry James in the palace of art : a survey and evaluation of James' aesthetic criteria as shown in his criticism of nineteenth century painting.
Creators: name: Thomas, Audrey
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this thesis is to provide a general introduction to the study of James' art criticism, to establish his aesthetic criteria and to indicate the relationship between his theory of art and the themes of his fiction. First, I have included an analysis of three stories concerning the artist and his craft: "The Madonna of the Future," "The Liar," and "The Real Thing." Drawing certain conclusions as to James’ view of the nature of art and the nature and function of the artist, I have then proceeded to examine his most important statements on nineteenth century painting. Although this is only a small portion of his many comments on not only the art of painting but all the Fine Arts, I have limited my discussion to painting for the sake of brevity and clarity, and to the nineteenth century because James is a nineteenth century novelist. I have attempted to show his amazing perception of the various aesthetic movements of his time and his sympathetic attitude towards the many pitfalls into which the artists of the nineteenth century fell. I have also tried to indicate briefly where James differed from the major art critics of the time, such as Ruskin, Pater and Baudelaire. I feel that certain conclusions can be drawn from a study of James' art criticism: one, that it is important to any serious study of his novels; two, that it is closely linked to certain twentieth century attitudes towards the nature of art; and three, that the aesthetic theory out of which James is working has a direct relation to both the form and content of his novels. His characters are acting out his own struggle for a compromise between the Real and the Ideal, and his theory of art and theory of life being one and the same, he feels that one should, in a certain sense, make of one's life a work of art.

description: We present results from a study of proto-globular cluster candidates in the interacting galaxy system Arp 284 (NGC 7714/5) using data from the Hubble Space Telescope. Previous studies of the Antennae and M51 have suggested that the majority of young massive star clusters dissolve within 20 Myr due to mass loss. We use the evolutionary synthesis code Starburst99 to estimate ages and extinctions for approximately 175 clusters visible with HST. We also use lower-resolution GALEX and ground-based H-alpha data to estimate the ages of the giant HII regions in which these clusters are found, and compare the Spitzer colours of these HII regions to those of star forming regions in other interacting systems. The ages are also used to aid in the interpretation of Chandra X-ray data. Clusters in the tidal tails of NGC 7714 are generally found to have ages less than 20 Myr, though observational limits make the significance of this result uncertain. Older clusters, though not numerous, have nearly the same spatial distribution within the imaged portion of NGC 7714 as young clusters. The cluster population in the bridge connecting the two galaxies appears to be older, but the data in this part of the system is too limited to draw firm conclusions. The ages of the giant HII regions in NGC 7714 are generally older than those of their constituent clusters, possibly indicating that the young clusters we detect are surrounded by their dispersed predecessors.

description: This study examines the factors influencing consumers’ intentions to adopt cryptocurrency as a payment method in Bahrain whilst moderating for subjective norms. The theoretical framework used in this study was the Unified Theory of Acceptance and Use of Technology (UTAUT) framework. This study extends this model with additional constructs, including attitude, perceived trust, perceived risk and perceived security, to capture the unique dynamics of cryptocurrency adoption. The research employs a quantitative approach using Partial Least Squares Structural Equation Modeling (PLS-SEM), to analyze data collected from 314 respondents through an online survey. The results show that perceived usefulness, social influence, facilitating conditions, attitude, and perceived security positively influences consumers intentions to adopt cryptocurrency in Bahrain. On the other hand, perceived ease of use, perceived risk, and perceived trust were found to have no statistically significant effect on the intention to adopt cryptocurrency. This study found that subjective norms positively moderates the relationship between perceived security and intentions to adopt. This result highlights the importance of security perceptions and social validation on cryptocurrency adoption in Bahrain. This paper offers several recommendations to policymakers, cryptocurrency exchanges, and merchants to encourage wider adoption of cryptocurrency in Bahrain. This research contributes to the growing body of literature on technology adoption and more specifically cryptocurrency adoption, by examining how technology adoption constructs interact with subjective norms. By doing so, this study provides deeper insight into the factors influencing intentions to adopt cryptocurrency.

description: We discuss the role of dislocation assemblies such as grain boundaries in the dynamic response of a driven vortex lattice. We simulate the depinning of a field-cooled vortex polycrystal and observe a general enhancement of the critical current as well as a distinct crossover in the characterisitic of this quantity as a function of pinning density. The results agree with analytical predictions for grain boundary depinning. The dynamics of grain boundaries thus proves an essential mechanism underlying the flow response of defected vortex lattices and the corresponding transport properties of the superconducting material. We emphasize the connection between the topological rearrangements of the lattice and its threshold dynamics. Our theory encompasses a variety of experimental observations in vortex matter as well as in colloidal crystals.

description: {Context} Recent investigations of the white dwarf (WD) + He star channel of Type Ia supernovae (SNe Ia) imply that this channel can produce SNe Ia with short delay times. The companion stars in this channel would survive and be potentially identifiable. {Aims} In this Letter, we study the properties of the companion stars of this channel at the moment of SN explosion, which can be verified by future observations. {Methods} According to SN Ia production regions of the WD + He star channel and three formation channels of WD + He star systems, we performed a detailed binary population synthesis study to obtain the properties of the surviving companions. {Results} We obtained the distributions of many properties of the companion stars of this channel at the moment of SN explosion. We find that the surviving companion stars have a high spatial velocity (>400 km/s) after SN explosion, which could be an alternative origin for hypervelocity stars (HVSs), especially for HVSs such as US 708.

description: The meeting took place on May 30-June 3, 2011, with over 55 people in attendance. Each day had 6 to 7 talks of varying length (some talks were 30 minutes long), except for Thursday: the traditional hike was moved to Thursday due to the weather (and weather on thursday was indeed fine). The talks reviewed directions in which progress in the general field of stochastic analysis occurred since the last meeting of this theme in Oberwolfach three years ago. Several themes were covered in some depth, in addition to a broad overview of recent developments. Among these themes a prominent role was played by random matrices, random surfaces/planar maps and their scaling limits, the KPZ universality class, and the interplay between SLE (Schramm-Loewner equation) and the GFF (Gaussian free field).

description: В 1994 г. доктор Bertina RM, et al. обнаружили Лейденскую мутацию фактора свертывания V, наиболее распространенную причину тромбофилии, имеющую место у 5% европейцев. С тех пор сотни тысяч людей по страдали от тромбоэмболии венозного происхождения, и многие из них погибли из-за наличия этой мутации. В настоящее время общий скрининг для выявления этой мутации не проводится. Обзор публикаций по патофизиологии Лейденской мутации, ее распространенности и взаимодействию с различными, часто встречающимися обстоятельствами, такими как прием контрацептивов per os, беременность и хирургические вмешательства, показывает необходимость общего скрининга. В эпоху медицины ориентированной на пациента естественно, что пациенты заслуживают право знать о наличии у них Лейденской мутации для того, чтобы принимать обоснованные решения не только в выборе противозачаточных средств, но и для контроля различных обстоятельств высокого риска. Эта редакционная статья направлена на привлечение внимания к данной проблеме и предложение гипотезы. Следует или не следует проводить популяционные скрининги для выявления этого частого и угрожающего жизни нарушения?In 1994
description: Dr. Bertina et al. discovered Factor Five Leiden, the most common cause of the thrombophilias, occurring in 5% of the Caucasian population. Since then, hundreds of thousands of individuals have experienced venous thromboembolic events and many have died as a consequence of this mutation. Currently global screening for this mutation has not been advocated. A review of the Factor Five Leiden pathophysiology, prevalence, and impact on a variety of common conditions such as oral contraception, pregnancy, and surgery helps establish the case for global screening. In this era of patient-centric medicine, the contention is that patients deserve the right to know their Factor Five Leiden status in order to make informed decisions about not only birth control choices, but also management during high-risk circumstances. This editorial is meant to be thought provoking and hypothesis generating. Should we or should we not screen the public for this common and life-threatening disorder?

description: It is shown that exterior complex scaling provides for complete absorption of outgoing flux in numerical solutions of the time-dependent Schrödinger equation with strong infrared fields. This is demonstrated by computing high harmonic spectra and wave-function overlaps with the exact solution for a one-dimensional model system and by three-dimensional calculations for the H atom and a Ne atom model. We lay out the key ingredients for correct implementation and identify criteria for efficient discretization.

description: The FENICE detector, installed at the Frascati e+e- storage ring ADONE, for measuring the neutron e.m. form factors in the time-like region, is described. FENICE is a non magnetic detector and consists of a complex array of scintillators, limited streamer tubes and iron converters for detecting mainly the process e^+e^- -> n ̅n. Antineutrons are identified by the charged prongs produced in their annihilation and the antineutron velocity is measured by the revieved annihilation time respect to the beam crossing time. Neutrons are detected in plastic scintillator layers. To reduce the cosmic rays background a concrete shield, covered by an active veto system, is added.

description: This report arises from an ongoing program to monitor Neptune's largest moon Triton spectroscopically in the 0.8 to 2.4 micron range using IRTF/SpeX. Our objective is to search for changes on Triton's surface as witnessed by changes in the infrared absorption bands of its surface ices N2, CH4, H2O, CO, and CO2. We have recorded infrared spectra of Triton on 53 nights over the ten apparitions from 2000 through 2009. The data generally confirm our previously reported diurnal spectral variations of the ice absorption bands (Grundy & Young 2004). Nitrogen ice shows a large amplitude variation, with much stronger absorption on Triton's Neptune-facing hemisphere. We present evidence for seasonal evolution of Triton's N2 ice: the 2.15 micron absorption band appears to be diminishing, especially on the Neptune-facing hemisphere. Although it is mostly dissolved in N2 ice, Triton's CH4 ice shows a very different longitudinal variation from the N2 ice, challenging assumptions of how the two ices behave. Unlike Triton's CH4 ice, the CO ice does exhibit longitudinal variation very similar to the N2 ice, implying that CO and N2 condense and sublimate together, maintaining a consistent mixing ratio. Absorptions by H2O and CO2 ices show negligible variation as Triton rotates, implying very uniform and/or high latitude spatial distributions for those two non-volatile ices.

description: A new eremophilane sesquiterpene, named engleromophilane (1) together with known eremoxylarin E (2) and steroids (3-7) were isolated from the fungus Engleromyces sinensis culture. The structures were deduced by the analysis of spectroscopic and MS data, together with the comparison of calculated 13C NMR chemical shifts and Electronic Circular Dichroism (ECD) spectra. Compound 1 showed cytotoxic effects against Hela, PC-3, HT29 and A549 cell lines with IC50 in the ranges of 4.84–9.48 μg/mL. Compounds 1 and 2 exhibited substantial antimicrobial activity against E. coli, S. aureus, and B. subtilis. Moreover, compounds 1–3 showed α-glucosidase inhibitory activity, in which 2 displayed a strong inhibitory effect with an IC50 value of 0.13 ± 0.01 µg/mL. This work has given additional value to the E. sinensis fungus as a remarkable bioactive compound producer, together with the possibility of increasing cultivation to industrial scales.

To clarify the parameters that determine these life cycles, we introduce the conditional market share-defined as the probability that a product is selected by customers only if it had been previously purchased-and the market share without any conditions. The product life cycle is more strongly correlated with the conditional market share of the product than with the latter type of market share.

description: We report a comprehensive investigation of the local structure around As in thin InAsxP1-x strined layers in InAsxP1-x/Inp superlattices by fluorescence-detected x-ray absorption fine structure; seven superlattice samples are studied as a function of composition, and compared to six unstrained, bulk samples of similar composition. Contributions up to the third coordination shell around As are clearly visible in the spectra, and are analyzed taking into account important multiple-scattering contributions. Results show that structural modifications due to tetragonal distortion appear mainly in the second and third coordination shells, while nearest-neighbor bond lengths remain closer to the values in unstrained bulk alloys. This implies that in semiconductor alloy tetragonal strain accomodation is mainly obtained through bond-angle distortions, in analogy to the situation in bulk pseudobinary alloys. A model which combines macroscopic elastic theory and the known local structure in bulk pseudobinary alloy is presented, and is found to fit the data very well.

description: The application of quadrupole-devices with high field gradients and small apertures requires precise control over higher order multipole field components. We present a new scheme for performance control and tuning, which allows the illumination of most of the quadrupole-device aperture because of the reduction of higher order field components. Consequently, the size of the aperture can be minimized to match the beam size achieving field gradients of up to 500 T/m at good imaging quality. The characterization method based on a Hall probe measurement and a Fourier analysis was confirmed using the high quality electron beam at the Mainz Microtron MAMI.

description: This paper presents and discusses a critical compilation of accurate, fundamental determinations of stellar masses and radii. We have identified 95 detached binary systems containing 190 stars (94 eclipsing systems, and alpha Centauri) that satisfy our criterion that the mass and radius of both stars be known to 3% or better. To these we add interstellar reddening, effective temperature, metal abundance, rotational velocity and apsidal motion determinations when available, and we compute a number of other physical parameters, notably luminosity and distance. We discuss the use of this information for testing models of stellar evolution. The amount and quality of the data also allow us to analyse the tidal evolution of the systems in considerable depth, testing prescriptions of rotational synchronisation and orbital circularisation in greater detail than possible before. The new data also enable us to derive empirical calibrations of M and R for single (post-) main-sequence stars above 0.6 M(Sun). Simple, polynomial functions of T(eff), log g and [Fe/H] yield M and R with errors of 6% and 3%, respectively. Excellent agreement is found with independent determinations for host stars of transiting extrasolar planets, and good agreement with determinations of M and R from stellar models as constrained by trigonometric parallaxes and spectroscopic values of T(eff) and [Fe/H]. Finally, we list a set of 23 interferometric binaries with masses known to better than 3%, but without fundamental radius determinations (except alpha Aur). We discuss the prospects for improving these and other stellar parameters in the near future.

Samuel Johnson's views on women : from his works.
Creators: name: Stacey, Iris
Publisher: name: University of British Columbia
Year: 2011

description: An examination of Samuel Johnson’s essays and his tragedy, Irene, and his Oriental tale, Rasselas, reveals that his concept of womanhood and his views on the education of woman and her role in society amount to a thorough-going criticism of the established views of eighteenth-century society. His views are in advance of those of his age. Johnson viewed the question of woman with that same practical good sense which he had brought to bear on literary criticism. It was important he said "to distinguish nature from custom: or that which is established because it was right, from that which is right only because it is established." Johnson thought that, so far as women were concerned, custom had dictated views and attitudes which reason denied. Because society's concept of womanhood emphasized the physical and Johnson’s, the mental, there was little agreement about her education and her role in the home. Johnson's views on women will be drawn from his works rather than from comments recorded by his biographers, James Boswell, Mrs. Thrale, or Sir John Hawkins, or from remarks made in the diaries and letters of Fanny Burney and Hannah More. With the exception of excerpts in Chapter V, comments made by others will be used only as substantiating evidence. In Chapter V, I have found it necessary to draw heavily on comments made by others simply because Johnson passed few remarks about anyone he knew — man or woman. Chapter I sets forth eighteenth-century views on women from the viewpoint of society and from that of such men of letters as Addison, Steele, Pope, Defoe, Swift, and Johnson. The next two chapters will follow a chronological order; the discussion of Johnson’s views on the education of women will precede his views on marriage and the woman's role in the home. The fourth chapter, a discussion of Johnson's figure of womanhood from Irene and Rasselas can be considered as a summation of Chapters II and III, for these two works are really, a comprehensive study of what Johnson had said about the education of women and their role in society in his Rambler, Idler, and Adventurer. This chapter will also include an analysis of Johnson's female characters as women. The purpose of the concluding chapter is to show that Johnson's estimation of womankind and his views on the education of women and their role in society are not to be taken lightly. Many men express one opinion about women but really believe something quite different. But not Johnson. He chose his female friends for those same qualities he said in his works were becoming womanhood. In life he treated them as he had written of them — with respect and without condescension.
Low Emittance Photo-Injectors

description: Photon colliders require high charge polarized electron beams with very low normalized emittances, possibly lower than the actual damping rings design goals ( √(ε_nx 〖*ε〗_ny )≈〖10〗^(-7) m). Recent analytical and numerical efforts in understanding beam dynamics in rf photoinjectors have raised again the question whether the performances of an RF electron gun based injector could be competitive with respect to a damping ring. As a matter of discussion we report in this paper the most recent results concerning low emittance photoinjector designs: the production of polarized electron beams by DC and/or RF guns is illustrated together with space charge compensation techniques and thermal emittance effects. New ideas concerning multi-gun injection system and generation of flat beams by RF gun are also discussed.

Trapping Solids at the Inner Edge of the Dead Zone: 3-D Global MHD Simulations

description: The poorly-ionized interior of the protoplanetary disk is the location where dust coagulation processes may be most efficient. However even here, planetesimal formation may be limited by the loss of solid material through radial drift, and by collisional fragmentation of the particles. Our aim is to investigate the possibility that solid particles are trapped at local pressure maxima in the dynamically evolving disk. We perform the first 3-D global non-ideal MHD calculations of the disk treating the turbulence driven by the magneto-rotational instability. The domain contains an inner MRI-active region near the young star and an outer midplane dead zone, with the transition between the two modeled by a sharp increase in the magnetic diffusivity. The azimuthal magnetic fields generated in the active zone oscillate over time, changing sign about every 150 years. We thus observe the radial structure of the `butterfly pattern' seen previously in local shearing-box simulations. The mean magnetic field diffuses from the active zone into the dead zone, where the Reynolds stress nevertheless dominates. The greater total accretion stress in the active zone leads to a net reduction in the surface density, so that after 800 years an approximate steady state is reached in which a local radial maximum in the midplane pressure lies near the transition radius. We also observe the formation of density ridges within the active zone. The dead zone in our models possesses a mean magnetic field, significant Reynolds stresses and a steady local pressure maximum at the inner edge, where the outward migration of planetary embryos and the efficient trapping of solid material are possible.
