description: Since we can resolve the surface of the Sun directly, we can explore the origin of radial-velocity variations induced by individual solar surface features such as faculae/plage, sunspots and granulation.

I will present my recent investigation of the radial-velocity variations of the Sun as a star, based on high-resolution HARPS spectra of reflected sunlight and simultaneous images from the Solar Dynamics Observatory. We found that faculae are the dominant source of activity-induced radial-velocity variations, via suppression of convective blueshift. We investigated possible proxies for activity-induced radial-velocity variations and found that optical lightcurves can only provide a partial representation of these signals; the full-disc magnetic flux, however, is an excellent tracer. In addition to this dataset, the HARPS-N spectrograph has been operating with a new solar telescope feed since 2015 July. I will present results from the first year observations, which show radial-velocity variations of up to 7-8 m/s.

Identifying proxies for solar radial-velocity variations is key to understanding the radial-velocity variability of other Sun-like stars, and is also essential for other investigations such as exoplanet detection surveys.

description: Community structure plays a significant role in the analysis of social networks and similar graphs, yet this structure is little understood and not well captured by most models. We formally define a community to be a subgraph that is internally highly connected and has no deeper substructure. We use tools of combinatorics to show that any such community must contain a dense Erdös-Rényi (ER) subgraph. Based on mathematical arguments, we hypothesize that any graph with a heavy-tailed degree distribution and community structure must contain a scale free collection of dense ER subgraphs. These theoretical observations corroborate well with empirical evidence. From this, we propose the Block Two-Level Erdös-Rényi (BTER) model, and demonstrate that it accurately captures the observable properties of many real-world social networks.
Dreamspace and Dreamtime: Ritual and Information Management in Aboriginal Australia

description: Following a recent re-evaluation of evidence from an archaeological site in SE Australia, the possibility of a 120 thousand years (ka) old human presence in the Fifth Continent has been suggested. However, the commonly accepted date for the peopling of Australia remains within the range of 50 - 65 ka. Even if the newly proposed date were halved, an uninterrupted 60 ka continuity in the same territory would raise a few questions regarding the transmission mechanisms that have enabled the retention of the massive amount of knowledge acquired during such an extended period, especially when considering the lack of demographic strength, which is believed to be a prerequisite for effective social learning. I argue that the emergence, developmental rate, and extent of Australian culture reflect an ‘additive’ strategy centred on a ritually regulated feedback loop between the volume of information flow and the level of social elaboration. The model forwarded in this paper is at odds with current theoretical approaches to cultural evolution in which Aboriginal traditions are often portrayed as living examples of Palaeolithic cross-cultural universals.

description: Who decides the future of open access, or, rather, who has the power to make decisions that can affect the future of open access? We believe that large scale, transformative, and inclusive progress on these questions can transpire when several entities, each with different complementary powers, convene to collaborate on win-win solutions. We offer three examples of such possible scenarios: the way scholars are evaluated, the way some innovations in scholarly publishing can be nurtured, and the way global cooperation can transform existing journals to open access.
OSI2016 Workgroup Question
Tied to [the] question of who should decide the future of open access, who should have the power to make changes to scholarly publishing practices? Do these powers flow from publishers, institutions, tenure committees, funding agencies, authors, or all of the above? All of the above? None of the above? What are the pros, cons, and consequences of different institutions and interest groups developing and implementing their own solutions (even the one-off variety)? Is federal oversight needed? Global coordination (through an organization like UNESCO)?

description: Foreground removal is a challenge for 21-cm tomography of the high redshift Universe. We use archival GMRT data (obtained for completely different astronomical goals) to estimate the foregrounds at a redshift ~ 1. The statistic we use is the cross power spectrum between two frequencies separated by Δν at the angular multipole l, or equivalently the multi-frequency angular power spectrum C_l(Δν). An earlier measurement of C_l(Δν) using this data had revealed the presence of oscillatory patterns along Δν, which turned out to be a severe impediment for foreground removal (Ghosh et al. 2011). Using the same data, in this paper we show that it is possible to considerably reduce these oscillations by suppressing the sidelobe response of the primary antenna elements. The suppression works best at the angular multipoles l for which there is a dense sampling of the u-v plane. For three angular multipoles l = 1405, 1602 and 1876, this sidelobe suppression along with a low order polynomial fitting completely results in residuals of (\leq 0.02 mK^2), consistent with the noise at the 3σ level. Since the polynomial fitting is done after estimation of the power spectrum it can be ensured that the estimation of the HI signal is not biased. The corresponding 99% upper limit on the HI signal is xHI b \leq 2.9, where xHI is the mean neutral fraction and b is the bias.

Molecular dynamics simulations of thermal conductivity and spectral phonon relaxation time in suspended and supported graphene

description: We perform molecular dynamics (MD) simulations with phonon spectral analysis aiming at understanding the two dimensional (2D) thermal transport in suspended and supported graphene. Within the framework of equilibrium MD simulations, we perform spectral energy density (SED) analysis to obtain the lifetime of individual phonon modes. The per-mode contribution to thermal conductivity is then calculated to obtain the lattice thermal conductivity in the temperature range 300-650 K. In contrast to prior studies, our results suggest that the contribution from out-of-plane acoustic (or ZA) branch to thermal conductivity is around 25-30% in suspended single-layer graphene (SLG) at room temperature. The thermal conductivity is found to reduce when SLG is put on amorphous SiO2 substrate. Such reduction is attributed to the strengthened scattering in all phonon modes in the presence of the substrate. Among them, ZA modes are mostly affected with their contribution to thermal conductivity reduced to around 15%. As a result, thermal transport is dominated by in-plane acoustic phonon modes in supported SLG.

Konzeptionelle Präzisierung und neue Anwendungsfelder" (Derboven, Dick, Waibel & Wehner, 1996) an, in welchem unsere konzeptionelle, operative und evaluierende Arbeit mit Problemlösezirkeln in verschiedenen Verwaltungs- und Servicebereichen sowie im zwischenbetrieblichen Bereich vorgestellt und wesentliche Analyse- und Gestaltungsfelder von Zirkeln abgeleitet werden. In diesem Beitrag lösen wir das Zirkelkonzept vom Fokus des Problemlöseinstruments und erweitern es in zwei Stufen zum Instrument der Erfahrungsnutzung und der Wissensentwicklung. Die Zielsetzungen knüpfen an die aktuelle Diskussion über Wandel in Unternehmen an. Die veränderten Auffassungen über Rollen und Aufgaben von Mitarbeitern setzen einen veränderten Umgang mit Demokratie, Emanzipation und Wissen in den Unternehmen voraus. Da Zirkel in ihrer Veränderungsarbeit sowohl am Verhalten der Mitarbeiter als auch an den Verhältnissen im Unternehmen ansetzen, erscheinen sie geeignet, sowohl den kollektiven als auch den individuellen Umgang mit Arbeitsteilung und Wissen neu zu gestalten und zu effektivieren. Während Zirkel im Harburger Beitrag Nr. 11 als Partizipationsräume dargestellt wurden, die eine gestaltende Teilhabe von Ausführenden am unternehmerischen Wandel ermöglichen, werden sie in diesem Beitrag als Erfahrungs- und Wissensräume vorgestellt, in denen die Handlungsregulationsgrundlagen, die einem Kollektiv zur Aufgabenbewältigung zur Verfügung stehen, erweitert werden können. Die konzeptionelle Erneuerung berücksichtigt dabei auch die methodische Gestaltung der Zirkel. Hier sind Anpassungen an die veränderten Zielsetzungen besonders notwendig, da sich bisher in der ansonsten breit angelegten Qualitätszirkelliteratur weder Diskussionsräume noch Gestaltungsforen für den methodischen Rahmen konstituiert haben.

description: Raindrops impacting water surfaces such as lakes or oceans produce myriads of tiny droplets which are ejected into the atmosphere at very high speeds. Here we combine computer simulations and experimental measurements to investigate whether these droplets can serve as transport vehicles for the transition of microplastic particles with diameters of a few tens of μm from ocean water to the atmosphere. Using the Volume-of-Fluid lattice Boltzmann method, extended by the immersed-boundary method, we performed more than 1600 raindrop impact simulations and provide a detailed statistical analysis on the ejected droplets. Using typical sizes and velocities of real-world raindrops – parameter ranges that are very challenging for 3D simulations – we simulate straight impacts with various raindrop diameters as well as oblique impacts. We find that a 4mm diameter raindrop impact on average ejects more than 167 droplets. We show that these droplets indeed contain microplastic concentrations similar to the ocean water within a few millimeters below the surface. To further assess the plausibility of our simulation results, we conduct a series of laboratory experiments, where we find that microplastic particles are indeed contained in the spray. Based on our results and known data – assuming an average microplastic particle concentration of 2.9 particles per liter at the ocean surface – we estimate that, during rainfall, about 4800 microplastic particles transition into the atmosphere per square kilometer per hour for a typical rain rate of 10mmh and vertical updraft velocity of 0.5ms.

description: Various computer vision problems and applications rely on an accurate, fast head pose estimator. We model head pose estimation as a regression problem. We show that it is possible to use the appearance of the facial image as a feature which depicts the pose variations. We use a parametrized Multi-Variate Relevance Vector Machine (MVRVM) to learn the three rotation angles of the face (yaw, pitch, and roll). The input of the MVRVM is normalized mean pixel intensities of the face patches, and the output is the three head rotation angles. We evaluated our approach on the challenging YouTube faces dataset. We achieved a head pose estimation with an average error tolerance of ±6.5∘ in the yaw rotation angle, and less than ±2.5∘ in both the pitch and roll angles. The time taken in one prediction is 2-3 milliseconds, hence suitable for real-time applications.

description: Deactivation processes of photoexcited (λex = 580 nm) phycocyanobilin (PCB) in methanol were investigated by means of UV/Vis and mid-IR femtosecond (fs) transient absorption (TA) as well as static fluorescence spectroscopy, supported by density-functional-theory calculations of three relevant ground state conformers, PCBA, PCBB and PCBC, their relative electronic state energies and normal mode vibrational analysis. UV/Vis fs-TA reveals time constants of 2.0, 18 and 67 ps, describing decay of PCBB*, of PCBA* and thermal re-equilibration of PCBA, PCBB and PCBC, respectively, in line with the model by Dietzek et al. (Chem Phys Lett 515:163, 2011) and predecessors. Significant substantiation and extension of this model is achieved first via mid-IR fs-TA, i.e. identification of molecular structures and their dynamics, with time constants of 2.6, 21 and 40 ps, respectively. Second, transient IR continuum absorption (CA) is observed in the region above 1755 cm−1 (CA1) and between 1550 and 1450 cm−1 (CA2), indicative for the IR absorption of highly polarizable protons in hydrogen bonding networks (X–H…Y). This allows to characterize chromophore protonation/deprotonation processes, associated with the electronic and structural dynamics, on a molecular level. The PCB photocycle is suggested to be closed via a long living (> 1 ns), PCBC-like (i.e. deprotonated), fluorescent species.

Huntington disease : death, psychiatry and health services
Creators: name: Halpin, Michael
Publisher: name: University of British Columbia
Year: 2010

description: Huntington Disease (HD) is a genetic, degenerative neurological illness that affects mood, cognition and motor movement. Complications from the disease result in death 10 to 15 years post-diagnosis. However, individuals may be aware that they have HD years before the development of the most severe effects. Drawing on in-depth, qualitative interviews with 20 individuals with HD and 10 informal caregivers, this thesis explores the salient experiences that occur outside of predictive genetic testing. Findings emerged in four areas; namely, attitudes towards death and suicide, experiences with psychiatry, interactions with health services and bureaucracies, and the needs and experiences of caregivers. Participant accounts also form the basis for a number of health services recommendations, including trajectory-specific support groups and the need for disability benefits that are sensitive to the realities of HD. The thesis also explores the numerous ambiguities that HD creates for conceptual categories, specifically in relation to diagnosis, death and illness experience.

description: We consider N identical two-level atoms coupled to an optical cavity, which is coherently driven by an external field. In the limit of small atomic excitation, the reflection and transmission coefficients for both fields and intensities are calculated analytically. In addition, the frequency content of the cavity field and hence also the emission spectrum of the cavity is determined. It is discussed in particular how individual collisional dephasing and common atomic energy-level fluctuations prevent the cavity field from being in a coherent state, which in turn affects the outgoing fields.

description: Most microorganisms in the biosphere remain uncultured and poorly characterized. Although the surge in genome sequences has enabled insights into the genetic and metabolic properties of uncultured microorganisms, their physiology and ecological roles cannot be determined without direct probing of their activities in natural habitats. Here we employed an experimental framework coupling genome reconstruction and activity assays to characterize the largely uncultured microorganisms responsible for aerobic biodegradation of biphenyl as a proxy for a large class of environmental pollutants, polychlorinated biphenyls. We used 13C-labeled biphenyl in contaminated soils and traced the flow of pollutant-derived carbon into active cells using single-cell analyses and protein–stable isotope probing. The detection of 13C-enriched proteins linked biphenyl biodegradation to the uncultured Alphaproteobacteria clade UBA11222, which we found to host a distinctive biphenyl dioxygenase gene widely retrieved from contaminated environments. The same approach indicated the capacity of Azoarcus species to oxidize biphenyl and suggested similar metabolic abilities for species of Rugosibacter. Biphenyl oxidation would thus represent formerly unrecognized ecological functions of both genera. The quantitative role of these microorganisms in pollutant degradation was resolved using single-cell-based uptake measurements. Our strategy advances our understanding of microbially mediated biodegradation processes and has general application potential for elucidating the ecological roles of uncultured microorganisms in their natural habitats.
Melt homogenization and self-organization of chalcogenides glasses: evidence of sharp rigidity, stress and nanoscale phase separation transitions in the GexSe100-x binary

description: A Raman profiling method is used to monitor growth of GexSe100-x melts and reveals a two step process of homogenization. Resulting homogeneous glasses show the non-reversing enthalpy at Tg, ΔHnr(x), to show a square-well like variation with x, with a rigidity transition near xc(1) = 19.5(5)% and stress transition near xc(2) = 26.0(5)%) representing the boundaries of the rigid but stress-free Intermediate Phase (IP). The square-well like variation of ΔHnr(x) develops sloping walls, a triangular shape and eventually disappears in glasses having an increasing heterogeneity. The ΔHnr term ages over weeks outside the IP but not inside the IP. An optical analogue of the reversibility window is observed with Raman spectra of as-quenched melts and Tg cycled glasses being the same for glass compositions in the IP but different for compositions outside the IP. Variations of Molar volumes, display three regimes of behavior with a global minimum in the IP and a pronounced increase outside that phase. The intrinsic physical behavior of dry and homogeneous chalcogenides glasses can vary sharply with composition near elastic and chemical phase transitions, showing that the physics of network glasses requires homogeneous samples, and may be far more interesting than hitherto recognized.

description: Principles of economics predict that the costs associated with obtaining rewards can influence choice. When individuals face choices between a smaller, immediate option and a larger, later option, they often experience opportunity costs associated with waiting for delayed rewards because they must forego the opportunity to make other choices. We evaluated how reducing opportunity costs affects delay tolerance in capuchin monkeys. After choosing the larger option, in the High cost condition, subjects had to wait for the delay to expire, whereas in the Low cost different and Low cost same conditions, they could perform a new choice during the delay. To control for the effect of intake rate on choices, the Low cost same condition had the same intake rate ratio as the High cost condition. We found that capuchins attended both to intake rates and to opportunity costs. They chose the larger option more often in the Low cost different and Low cost same conditions than in the High cost condition, and more often in the Low cost different condition than in the Low cost same condition. Understanding how non-human primates represent and use costs in making decisions not only helps to develop theoretical frameworks to explain their choices but also addresses similarities with and differences from human decision-making. These outcomes provide insights into the origins of human economic behaviour.This article is part of the theme issue ‘Existence and prevalence of economic behaviours among non-human primates’.

description: We present an asteroseismic study of the solar-like stars KIC 11395018, KIC 10273246, KIC 10920273, KIC 10339342, and KIC 11234888 using short-cadence time series of more than eight months from the Kepler satellite. For four of these stars, we derive atmospheric parameters from spectra acquired with the Nordic Optical Telescope. The global seismic quantities (average large frequency separation and frequency of maximum power), combined with the atmospheric parameters, yield the mean density and surface gravity with precisions of 2% and ~0.03 dex, respectively. We also determine the radius, mass, and age with precisions of 2-5%, 7-11%, and ~35%, respectively, using grid-based analyses. We determine asteroseismic distances to these stars with a precision better than 10%, and constrain the stellar inclination for three of the stars. An Li abundance analysis yields an independent estimate of the age, but this is inconsistent with the asteroseismically determined age for one of the stars. We compare the results from five different grid-based analyses, and we find that they all provide radius and mass values to within 2.4sigma. The absence of a metallicity constraint when the average large frequency separation is measured with a precision of 1% biases the fitted radius and mass for the stars with non-solar metallicity (metal-rich KIC 11395018 and metal-poor KIC 10273246), while including a metallicity constraint reduces the uncertainties in both of these parameters by almost a factor of two. We found that including the average small frequency separation improves the determination of the age only for KIC 11395018 and KIC 11234888, and for the latter this improvement was due to the lack of strong atmospheric constraints.

description: Many research works focus on the adoption of cloud infrastructure as a service(IaaS), where virtual machines (VM) are deployed on multiple cloud service providers (CSP). In terms of virtual resource allocation driven by security requirements, most of proposals take the aspect of cloud client into account but do not address such requirements from CSP. Besides, it is a shared understanding that using a formal policy model to support the expression of security requirements can drastically ease the cloud resource management and conflict resolution. To address these theoretical limitations, our work is based on a formal model that applies organization-based access control (OrBAC) policy to IaaS resource allocation. In this paper, we first integrate the attribute-based security requirements in service level agreement (SLA) contract. After transformation, the security requirements are expressed by OrBAC rules and these rules are considered together with other non-security demands during the enforcement of resource allocation. We have implemented a prototype for VM scheduling in OpenStack-based multi-cloud environment and evaluated its performance.
Covariant Gauge Fixing and Canonical Quantization

description: Theories that contain first class constraints possess gauge invariance which results in the necessity of altering the measure in the associated quantum mechanical path integral. If the path integral is derived from the canonical structure of the theory, then the choice of gauge conditions used in constructing Faddeev's measure cannot be covariant. This shortcoming is normally overcome either by using the "Faddeev-Popov" quantization procedure, or by the approach of Batalin-Fradkin-Fradkina-Vilkovisky, and then demonstrating that these approaches are equivalent to the path integral constructed from the canonical approach with Faddeev's measure. We propose in this paper an alternate way of defining the measure for the path integral when it is constructed using the canonical procedure for theories containing first class constraints and that this new approach can be used in conjunction with covariant gauges. This procedure follows the Faddeev-Popov approach, but rather than working with the form of the gauge transformation in configuration space, it employs the generator of the gauge transformation in phase space. We demonstrate this approach to the path integral by applying it to Yang-Mills theory, a spin-two field and the first order Einstein-Hilbert action in two dimensions. The problems associated with defining the measure for theories containing second-class constraints and ones in which there are fewer secondary first class constraints than primary first class constraints are discussed.

description: An earlier theory of the quantum phase transition in metallic ferromagnets is revisited and generalized in three ways. It is shown that the mechanism that leads to a fluctuation-induced first-order transition in metallic ferromagnets with a low Curie temperature is valid, (1) irrespective of whether the magnetic moments are supplied by the conduction electrons or by electrons in another band, (2) for ferromagnets in the XY and Ising universality classes as well as for Heisenberg ferromagnets, and (3) for ferrimagnets as well as for ferromagnets. This vastly expands the class of materials for which a first-order transition at low temperatures is expected, and it explains why strongly anisotropic ferromagnets, such as UGe2, display a first-order transition as well as Heisenberg magnets.

description: The interaction between different applications and services requires expressing their security properties. This is typically defined as security policies, which aim at specifying the diverse privileges of different actors. Today similarity measure for comparing security policies becomes a crucial technique in a variety of scenarios, such as finding the cloud service providers which satisfy client's security concerns. Existing approaches cover from semantic to numerical dimensions and the main work focuses mainly on XACML policies. However, few efforts have been made to extend the measure approach to multiple policy models and apply it to concrete scenarios. In this paper, we propose a generic and light-weight method to compare and evaluate security policies belonging to different models. Our technique enables client to quickly locate service providers with potentially similar policies. Comparing with other works, our approach takes policy elements' logic relationships into account and the experiment and implementation demonstrate the e ciency and accuracy of our approach.

description: Star formation in galaxies is observed to be associated with gamma-ray emission. The detection of gamma rays from star-forming galaxies by the Fermi Large Area Telescope (LAT) has allowed the determination of a functional relationship between star formation rate and gamma-ray luminosity (Ackermann et. al. 2012). Since star formation is known to scale with total infrared (8-1000 micrometers) and radio (1.4 GHz) luminosity, the observed infrared and radio emission from a star-forming galaxy can be used to quantitatively infer the galaxy's gamma-ray luminosity. Similarly, star forming galaxies within galaxy clusters allow us to derive lower limits on the gamma-ray emission from clusters, which have not yet been conclusively detected in gamma rays. In this study we apply the relationships between gamma-ray luminosity and radio and IR luminosities derived in Ackermann et. al. 2012 to a sample of galaxy clusters from Ackermann et. al. 2010 in order to place lower limits on the gamma-ray emission associated with star formation in galaxy clusters. We find that several clusters have predicted lower limits on gamma-ray emission that are within an order of magnitude of the upper limits derived in Ackermann et. al. 2010 based on non-detection by Fermi-LAT. Given the current gamma-ray limits, star formation likely plays a significant role in the gamma-ray emission in some clusters, especially those with cool cores. We predict that both Fermi-LAT over the course of its lifetime and the future Cherenkov Telescope Array will be able to detect gamma-ray emission from star-forming galaxies in clusters.

description: In this paper, we evaluate, analyze, and compare the impact of mobility on the behavior of three reactive protocols (AODV, DSR, DYMO) and three proactive protocols (DSDV, FSR, OLSR) in multi-hop wireless networks. We take into account throughput, end-to-end delay, and normalized routing load as performance parameters. Based upon the extensive simulation results in NS-2, we rank all of six protocols according to the performance parameters. Besides providing the interesting facts regarding the response of each protocol on varying mobilities and speeds, we also study the trade-offs, the routing protocols have to make. Such as, to achieve throughput, a protocol has to pay some cost in the form of increased end-to-end delay or routing overhead.
