description: During the preparatory phase of the International Linear Collider (ILC) project, all technical development and engineering design needed for the start of ILC construction must be completed, in parallel with intergovernmental discussion of governance and sharing of responsibilities and cost. The ILC Preparatory Laboratory (Pre-lab) is conceived to execute the technical and engineering work and to assist the intergovernmental discussion by providing relevant information upon request. It will be based on a worldwide partnership among laboratories with a headquarters hosted in Japan. This proposal, prepared by the ILC International Development Team and endorsed by the International Committee for Future Accelerators, describes an organisational framework and work plan for the Pre-lab. Elaboration, modification and adjustment should be introduced for its implementation, in order to incorporate requirements arising from the physics community, laboratories, and governmental authorities interested in the ILC.

description: We calculate the pion and rho meson masses in quenched SU(N) gauge theories for N = 2, 3, 4 and 6. Extrapolating these results to the chiral and large-N limits, we find m_rho = (1.670 +/- 0.024) sqrt(sigma) = (741 +/- 11) MeV for the rho meson mass at a fixed lattice spacing a \approx 0.2093 sqrt(sigma) \approx 0.093 fm where we use the (arbitrary) value (444 MeV)^2 for the string tension. We estimate a continuum limit large-N value, m_rho = 1.77 +/- 0.05 sqrt(sigma). We find 1/N^2 corrections to be small and we compare our results to predictions from AdS/QCD.

description: We analyze the electric field driven topological field effect transition on 2D-xene materials with the addition of momentum relaxation effects, in order to account for dephasing processes. The topological field effect transition between the quantum spin Hall phase and the quantum valley Hall phase is analyzed in detail using the Keldysh non-equilibrium Green's function technique with the inclusion of momentum and phase relaxation, within the self-consistent Born approximation. Details of the transition with applied electric field are elucidated for the ON-OFF characteristics with emphasis on the transport properties along with the tomography of the current carrying edge states. We note that for moderate momentum relaxation, the current carrying quantum spin Hall edge states are still pristine and show moderate decay with propagation. To facilitate our analysis, we introduce two metrics in our calculations, the coherent transmission and the effective transmission. In elucidating the physics clearly, we show that the effective transmission, which is derived rigorously from the quantum mechanical current operator is indeed the right quantity to analyze topological stability against dephasing. Exploring further, we show that the insulating quantum valley Hall phase, as a result of dephasing carries band-tails which potentially activates parasitic OFF currents, thereby degrading the ON-OFF ratios. Our analysis sets the stage for realistic modeling of topological field effect devices for various applications, with the inclusion of scattering effects and analyzing their role in the optimization of the device performance.

Learning needs and job satisfaction of community mental health workers
Creators: name: Quastel, Leah N.
Publisher: name: University of British Columbia
Year: 2010

description: The present study was conducted to determine the continuing education needs of community mental health workers, and to investigate the relationship between training need/opportunity discrepancies and job satisfaction. It was hypothesized that mental health workers with few learning need/opportunity discrepancies would be significantly more satisfied with their job than people in situations characterized by educational opportunities inadequate to meet self perceived learning needs. Congruence was invoked as an explanatory construct mediating the relationship between unmet learning needs and job satisfaction. A modified Delphi technique was employed to generate an inventory of skills, knowledges and attitudes required to perform community mental health work. Sixteen Delphi panelists identified 73 competencies which formed the item pool for a learning needs questionnaire. The Job Descriptive Index was adopted as a measure of job satisfaction. The Skills, Knowledges and Attitudes Inventory, together with the Job Descriptive Index and a seven item socio-demographic questionnaire, was administered to 103 health professionals working in eleven community mental health centres in the lower mainland of British Columbia. Learning needs were derived by scale score analysis. Fifty-three of 73 competencies on the Skills, Knowledges and Attitudes Inventory were identified as items for which more learning was required. The respondents perceived few competency gaps in tasks associated with traditional mental health work. The greatest needs for further training were identified in component parts of job tasks concerned with the evolving community oriented role, such as educating the public about mental health and illness and planning innovative therapeutic programs. The hypothesis was tested with a correlational design. The results strongly supported the contention that the greater the degree of discrepancy between learning needs and learning opportunities, the less the job satisfaction. There were significant negative correlations between all sections of the Skills, Knowledges and Attitudes Inventory and each facet of the Job Descriptive Index. The null hypothesis was rejected at the .01 level of significance. Stepwise regression supported the further conclusion that unmet learning needs were powerful predictors of job dissatisfaction. Discrepancy scores accounted for 11.6 per cent of the explained variance of job satisfaction as compared to 8.3 per cent of variance accounted for by all of the seven socio-demographic characteristics collectively. The single best predictor of job satisfaction was unmet learning needs in 'Treatment and Community Services' (beta=-.27). The most important implication of this study is that opportunities to engage in continuing professional education experiences to satisfy perceived learning needs appears to increase job satisfaction which may, in the long run, influence quality of patient care.

description: (abridged) Our long-term XMM-Newton program of long-term monitoring of a solar-like star with a well-studied chromospheric cycle, HD 81809 aims to study whether an X-ray cycle is present, along with studying its characteristics and its relation to the chromospheric cycle. Regular observations of HD 81809 were performed with XMM-Newton, spaced by 6 months from 2001 to 2007. We studied the variations in the resulting coronal luminosity and temperature, and compared them with the chromospheric CaII variations. We also modeled the observations in terms of a mixture of active regions, using a methodology originally developed to study the solar corona. Our observations show a well-defined cycle with an amplitude exceeding 1 dex and an average luminosity approximately one order of magnitude higher than in the Sun. The behavior of the corona of HD 81809 can be modeled well in terms of varying coverage of solar-like active regions, with a larger coverage than for the Sun, showing it to be compatible with a simple extension of the solar case.

description: We aim to characterize the physical and chemical properties of fragmented cores during the earliest evolutionary stages in the very young star-forming regions ISOSS J22478+6357 and ISOSS J23053+5953. NOEMA 1.3 mm data are used in combination with archival mid- and far-infrared observations to construct and fit the SEDs of individual fragmented cores. The radial density profiles are inferred from the 1.3 mm continuum visibility profiles and the radial temperature profiles are estimated from H2CO rotation temperature maps. Molecular column densities are derived with the line fitting tool XCLASS. The physical and chemical properties are combined by applying the physical-chemical model MUSCLE in order to constrain the chemical timescales of a few line-rich cores. The morphology and spatial correlations of the molecular emission are analyzed using the HOG method. The mid-infrared data show that both regions contain a cluster of young stellar objects. Bipolar molecular outflows are observed in the CO 2-1 transition toward the strong mm cores indicating protostellar activity. We find strong molecular emission of SO, SiO, H2CO, and CH3OH in locations which are not associated with the mm cores. These shocked knots can be either associated with the bipolar outflows or, in the case of ISOSS J23053+5953, with a colliding flow that creates a large shocked region between the mm cores. The mean chemical timescale of the cores is lower (20 000 yr) compared to that of the sources of the more evolved CORE sample (60 000 yr). With the HOG method, we find that the spatial emission of species tracing the extended emission and of shock-tracing molecules are well correlated within transitions of these groups.

Energy-Momentum of the Gravitational Field: Crucial Point for Gravitation Physics and Cosmology

description: A history of the problem of mathematical and physical definition for the energy-momentum of the gravity field is reviewed. As it was noted 90 years ago by Hilbert (1917), Einstein (1918), Schrodinger (1918) and Bauer (1918) within Geometrical Gravity approach (General Relativity) there is no tensor characteristics of the energy-momentum for the gravity field. Landau & Lifshitz (1971) called this quantity pseudo-tensor of energy-momentum and noted that Einstein's equations does not express the energy conservation for matter plus gravity field. This has crucial consequences for gravity physics and cosmology, such as negative energy density for static gravity field and violation of energy conservation in expanding space. However there is alternative Field Gravity approach for description of gravitation as a symmetric tensor field in Minkowski space, which is similar to description of all other physical interactions and based on well-defined positive, localizable energy-momentum of the gravity field. This relativistic quantum Field Gravity approach was partially developed by Firz & Pauli (1939), Birkhoff (1944), Thirring (1961), Kalman (1961), Feynman (1963) and others. Here it is shown that existence of well-defined positive energy-momentum of the gravity field leads to radical changes in gravity physics and cosmology, including such new possibilities as two-component nature of gravity - attraction (spin 2) and repulsion (spin 0), absence of black holes and singularities, scalar gravitational radiation caused by spherically symmetric gravitational collapse.

description: We consider the quantum electrodynamic corrections to the two-stream instability. We find these corrections vanish at first order unless a guiding magnetic field $\mathbf{B}_0$ is considered. With respect to the classical version of the instability, quantum electrodynamic effects reduce the most unstable wave vector and its growth rate by a factor $\sqrt{1+ξ}$, with $ξ= \fracα{9π} (B_0/B_{cr})^2$, where $α$ is the fine-structure constant and $B_{cr}$ the Schwinger critical magnetic field. Although derived for a cold system, these results are valid for the kinetic case. The results are valid in the range $ξ\ll 1$ and, actually, up to linear corrections in $ξ$.

description: We present the abundance measurements of several elements (Fe, Ca, Na, Ni, Ti, Al, Cr, Si) for 20 solar--type stars belonging to four Galactic open clusters: NGC 3680, IC 4651, Praesepe, and M 67. Oxygen abundances were in addition measured for most of the stars in each cluster apart from IC 4651. For NGC 3680 accurate abundance determinations using high--resolution spectra covering a large spectral domain are computed for the first time. We used UVES high--resolution, high signal to noise ratio spectra and performed a differential analysis with respect to the sun, by measuring equivalent widths and assuming LTE. The most surprising result is a significant supersolar metallicity for Praesepe ([Fe/H]=0.27+-0.10). As for the other clusters, we confirm a supersolar metallicity for IC 4651 ([Fe/H]=0.12+-0.05), a solar metallicity for M 67 ([Fe/H]=0.03+-0.04) and a slight subsolar metallicity for NGC 3680 ([Fe/H]=-0.04+-0.03). We find that the abundance ratios of almost all elements are solar, with the notable exception of oxygen in NGC 3680 and Praesepe, supersolar in the former cluster ([O/Fe]=0.2+-0.05) and as low as [O/Fe]=-0.4+-0.1 in the latter. Observations of several objects per cluster is required to obtain robust results, especially for those elements with a limited number of suitable lines.

description: The choroid is a highly vascularized tissues supplying the retinal pigment epithelium and photoreceptors. Its implication in retinal diseases is gaining increasing interest. However, investigating the anatomy and flow of the choroid remains challenging. Here we show that laser Doppler holography provides high contrast imaging of choroidal vessels in humans, with a spatial resolution comparable to state of the art indocyanine green angiography and optical coherence tomography. Additionally, laser Doppler holography contributes to sort out choroidal arteries and veins by using a power Doppler spectral analysis. We thus demonstrate the potential of laser Doppler holography to improve our understanding of the anatomy and flow of the choroidal vascular network.

description: We present the results of the first X-ray gratings spectroscopy observations of a planetary nebula (PN), the X-ray-bright, young BD+30 3639. We observed BD+30 3639 for a total of 300 ks with the Chandra X-ray Observatory's Low Energy Transmission Gratings in combination with its Advanced CCD Imaging Spectrometer(LETG/ACIS-S). The LETG/ACIS-S spectrum of BD+30 3639 is dominated by H-like resonance lines of O viii and C sc vi and the He-like triplet line complexes of Ne ix and O vii. Other H-like resonance lines, such as N vii, as well as lines of highly ionized Fe, are weak or absent. Continuum emission is evident over the range 6-18 A. Spectral modeling indicates the presence of a range of plasma temperatures from T~1.7x10^6 K to 2.9x10^6 K and an intervening absorbing column N_H~2.4x10^21 cm-2. The same modeling conclusively demonstrates that C and Ne are highly enhanced, with abundance ratios of C/O~15-45 and Ne/O~3.3-5.0 (90% confidence ranges, relative to the solar ratios), while N and Fe are depleted, N/O~0.0-1.0 and Fe/O~0.1-0.4. The intrinsic luminosity of the X-ray source determined from the modeling and the measured flux (F_X = 4.1x10^-13 ergs cm-2 s-1) is L_X~8.6x10^32 erg s-1(assuming D = 1.2kpc). These gratings spectroscopy results are generally consistent with earlier results obtained from X-ray CCD imaging spectroscopy of BD+30 3639, but are far more precise. The tight constraints placed on the (nonsolar) abundances directly implicate the present-day central star -- hence, ultimately, the intershell region of the progenitor asymptotic giant branch star -- as the origin of the shocked plasma now emitting in X-rays.

description: The concept of "Indonesian music" is complex and dynamic, shaped by diverse global influences and historical contexts. This discourse challenges the notion of a singular definition, highlighting the political, cultural, and ecological factors at play. Indonesian music has evolved through acculturation with Western traditions, leading to diversity and alienation. The discussion calls for a multifaceted approach that considers music's social, political, and historical dimensions and issues of participation, funding, and education. The book Sounding Indonesia, Indonesians Sounding aims to explore these complexities by gathering diverse perspectives from multiple disciplines to offer a more comprehensive understanding of Indonesian music.
The impact of a preventive health care program for older people on health status, knowledge and costs
Creators: name: Pickard, Lynette Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to test the claim that senior citizens who received preventive nursing services which were accessible and emphasized health promotion (through health education, counselling and early detection of disease) would have significantly lower health costs and significantly greater health status, knowledge and behaviour than those who received nursing services which were less accessible and placed less emphasis on health promotion. Residents of two apartment complexes for senior citizens in the West End of Vancouver (Nicholson and Sunset Towers) were participants in this study. The main differences between the nursing programs in these two complexes are the increased accessibility of the nurses in Nicholson Towers and the greater amount of health education and counselling which is done there. A sample of individuals from each complex was randomly selected for interviewing. Data collected from residents in a structured interview measured health knowledge, health behaviour, health status and variables identified in the literature as related to health knowledge and health status. The Medical Services Plan of B.C. and Pharmacare supplied data on number and cost of health services and cost of medication for individuals in the study over an eight month period. Data were computer analyzed using the University of British Columbia's version of SPSS. Results of the study indicated that average health costs were not significantly lower in the building in which preventive nursing services were available. Possible reasons for this unexpected finding are that Home Care nursing services are costly, that increased accessibility of Home Care nursing services leads to increased utilization and increased costs, that the ability to bring about improvement in health is limited by the aging process and that we may have unrealistic expectations of prevention programs. Residents of Nicholson Towers (who received preventive nursing services) were found to have significantly greater physical and social function than those in Sunset Towers (who did not receive preventive nursing services). Eligibility for Long Term Care accounts for a large percentage of variance in physical function and Nicholson Towers has a significantly (34% vs. 39%) smaller percentage of residents eligible for Long Term Care. This could account for the significantly greater physical function of residents in this complex. The social function scale evidenced low (.43) alpha reliability and low content and convergent validity. Findings regarding the significant differences between the complexes in terms of social function are therefore tenuous. Findings regarding health education in both complexes support the conclusion that there could be greater use of group methods and techniques of instruction. This is likely to increase both the effectiveness and efficiency of health education.

description: Since fullerene formation occurs under conditions where direct observation of atomic-scale reactions is not possible, modeling is the only way to reveal atomistic mechanisms which can lead to selection of abundant fullerene isomers (like C60-Ih). In the present paper we review the results obtained for different atomistic mechanisms by various modeling techniques. Although it seems that atomic-scale processes related to odd fullerenes (such as growth by consecutive insertions of single carbon atoms and rearrangements of the sp$^2$ structure promoted by extra sp atoms) provide the main contribution to selection of abundant isomers, at the moment there is no conclusive evidence in favor of any particular atomistic mechanism. Thus, the following multiscale modeling strategy to solve the mystery of the high yield of abundant fullerene isomers is suggested. On the one hand, sets of reactions between fullerene isomers can be described using theoretical graph techniques. On the other hand, reaction schemes can be revealed by classical molecular dynamics simulations with subsequent refinement of the activation barriers by ab initio calculations. Based on the reaction sets with the reaction probabilities derived in this way, the different atomistic mechanisms of abundant fullerene isomer selection can be compared by kinetic models.

description: Uniqueness problems in the elliptic sector of constrained formulations of Einstein equations have a dramatic effect on the physical validity of some numerical solutions, for instance when calculating the spacetime of very compact stars or nascent black holes. The fully constrained formulation (FCF) proposed by Bonazzola, Gourgoulhon, Grandclément, and Novak is one of these formulations. It contains, as a particular case, the approximation of the conformal flatness condition (CFC) which, in the last ten years, has been used in many astrophysical applications. The elliptic part of the FCF basically shares the same differential operators as the elliptic equations in CFC scheme. We present here a reformulation of the elliptic sector of CFC that has the fundamental property of overcoming the local uniqueness problems. The correct behavior of our new formulation is confirmed by means of a battery of numerical simulations. Finally, we extend these ideas to FCF, complementing the mathematical analysis carried out in previous studies.

description: By modifying a domain first suggested by Ruth Goodman in 1935 and by exploiting the explicit solution by Fedorov of the Polyá-Chebotarev problem in the case of four symmetrically placed points, an improved upper bound for the univalent Bloch-Landau constant is obtained. The domain that leads to this improved bound takes the form of a disk from which some arcs are removed in such a way that the resulting simply connected domain is harmonically symmetric in each arc with respect to the origin. The existence of domains of this type is established, using techniques from conformal welding, and some general properties of harmonically symmetric arcs in this setting are established.

description: In this work we study the flavor changing neutral current(FCNC) decays of the top quark, $t\to cγ$ and $t\to c g$. The Standard Model, predictions for the branching ratios of these decays are about $\sim 5\times 10^{-14}$, and $\sim 1\times 10^{-12}$, respectively. The recent study presented by the ATLAS Collaboration gives a sensitivity on these branching ratios about $\sim 10^{-5}$ at $%95$ C.L. The parameter space of $λ$, $Λ$, and $d$ where the branching ratios of $t\to cγ$ and $t\to c g$ decays exceed these predictions is obtained.

description: We create an ultracold dense quantum gas of ground state molecules bound by more than 1000 wavenumbers by stimulated two-photon transfer of molecules associated on a Feshbach resonance from a Bose-Einstein condensate of cesium atoms. The transfer efficiency exceeds 80%. In the process, the initial loose, long-range electrostatic bond of the Feshbach molecule is coherently transformed into a tight chemical bond. We demonstrate coherence of the transfer in a Ramsey-type experiment and show that the molecular sample is not heated during the transfer. Our results show that the preparation of a quantum gas of molecules in arbitrary rovibrational states is possible and that the creation of a Bose-Einstein condensate of molecules in their rovibronic ground state is within reach.

Introducing the LBT Imaging of Galactic Halos and Tidal Structures (LIGHTS) survey. A preview of the low surface brightness Universe to be unveiled by LSST

description: We present the first results of the LBT Imaging of Galaxy Haloes and Tidal Structures (LIGHTS) survey. LIGHTS is an ongoing observational campaign with the 2x8.4m Large Binocular Telescope (LBT) aiming to explore the stellar haloes and the low surface brightness population of satellites down to a depth of muV~31 mag/arcsec^2 (3 sigma in 10"x10" boxes) of nearby galaxies. We simultaneously collected deep imaging in the g and r Sloan filters using the Large Binocular Cameras (LBCs). The resulting images are 60 times (i.e. ~4.5 mag) deeper than those from the Sloan Digital Sky Survey (SDSS), and they have characteristics comparable (in depth and spatial resolution) to the ones expected from the future Legacy Survey of Space and Time (LSST). Here we show the first results of our pilot programme targeting NGC1042 (an M33 analogue at a distance of 13.5 Mpc) and its surroundings. The depth of the images allowed us to detect an asymmetric stellar halo in the outskirts of this galaxy whose mass (1.4+-0.4x10^8 Msun) is in agreement with the Lambda Cold Dark Matter (LambdaCDM) expectations. Additionally, we show that deep imaging from the LBT reveals low mass satellites (a few times 10^5 Msun) with very faint central surface brightness muV(0)~27 mag/arcsec^2 (i.e. similar to Local Group dwarf spheroidals, such as Andromeda XIV or Sextans, but at distances well beyond the local volume). The depth and spatial resolution provided by the LIGHTS survey open up a unique opportunity to explore the `missing satellites' problem in a large variety of galaxies beyond our Local Group down to masses where the difference between the theory and observation (if any) should be significant.

description: Day by day, the popularity of multi-level inverters (MLIs) for applications of high power and high voltage is growing. These MLIs, including solar photovoltaic (PV) systems, are being built into the grid for renewable energy extraction. The MLI induces a low harmonic material staircase output voltage and can pump a sinusoidal grid current with an increased power factor. The MLI based grid tied PV system will therefore work with reduced filter requirements at the lower switching frequency. The numerous MLIs, modulation and control techniques for grid connected applications are discussed in this article. A detailed classification of different grid connected Multi-level inverters (GCMLIs) based on the number and arrangement of DC voltage sources is presented. For various MLI based PV systems that communicate with the utility grid, various control techniques and modulation techniques have also been addressed. For a deeper understanding and reliability of past and future PV system technologies, this paper also provides detailed comparisons and discussion of different control techniques used in single phase and three phase grid connected MLI.

New Possibilities for Observational Distinction Between Geometrical and Field Gravity Theories
Creators: name: Baryshev, Yu. V.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

subject: FOS: Physical sciences

description: Crucial observational tests of gravity physics are reviewed. Such tests are able to clarify the key question on the nature of gravitational interaction: is gravity the curvature of space? or is gravity a matter field in Minkowski flat space as other physical forces? Up to now all actually performed experiments do not allow to distinguish between these two alternatives in gravity physics. The existence of well-defined positive energy-momentum of the gravity field in Poincare-Feynman approach leads to radical changes in gravity physics and cosmology which may be tested by laboratory experiments and astrophysical observations. New possibilities for observational distinction between geometrical general relativity and field gravity theories are discussed. Among them: the contribution of the scalar repulsive force into Newtonian gravitational interaction, post-Newtonian translational motion of rotating bodies, gravitational deflection of light by small mass bodies, scalar gravitational radiation from spherically pulsating stars, existence of limiting radius, surface, magnetic field for massive bodies and absence of singularities and horizons for relativistic compact objects.

Radiative polarization dynamics of relativistic electrons in an intense electromagnetic field

description: We propose a self-consistent model which utilizes the polarization vector to theoretically describe the evolution of spin polarization of relativistic electrons in an intense electromagnetic field. The variation of radiative polarization due to instantaneous no photon emission is introduced into our model, which extends the applicability of the polarization vector model derived from the nonlinear Compton scattering under local constant crossed-field approximation to the complex electromagnetic environment in laser plasma interaction. According to this model, we develop a Monte Carlo method to simulate the electron spin under the influence of radiation and precession simultaneously. Our model is consistent with the quantum physical picture that spin can only be described by a probability distribution before measurement, and it contains the entire information on the spin. The correctness of our model is confirmed by the successful reproduction of the Sokolov-Ternov effect and the comparison of the simulation results with other models in the literature. The results show the superiority in accuracy, applicability, and computational efficiency of our model, and we believe that our model is a better choice to deal with the electron spin in particle-in-cell simulation for laser plasma interaction.
