description: We examine mobility and saturation velocity in graphene on SiO2 above room temperature (300-500 K) and at high fields (~1 V/um). Data are analyzed with practical models including gated carriers, thermal generation, "puddle" charge, and Joule heating. Both mobility and saturation velocity decrease with rising temperature above 300 K, and with rising carrier density above 2x10^12 cm^-2. Saturation velocity is >3x10^7 cm/s at low carrier density, and remains greater than in Si up to 1.2x10^13 cm^-2. Transport appears primarily limited by the SiO2 substrate, but results suggest intrinsic graphene saturation velocity could be more than twice that observed here.

description: We report initial results from the far-infrared fine structure line observations of a sample of 44 local starbursts, Seyfert galaxies and infrared luminous galaxies obtained with the PACS spectrometer on board Herschel. We show that the ratio between the far-infrared luminosity and the molecular gas mass, Lfir/MH2, is a much better proxy for the relative brightness of the far-infrared lines than Lfir alone. Galaxies with high Lfir/MH2 ratios tend to have weaker fine structure lines relative to their far-infrared continuum than galaxies with Lfir/MH2 < 80 Lsun/Msun. A deficit of the [C II] 158 micron line relative to Lfir was previously found with the ISO satellite, but now we show for the first time that this is a general aspect of all far-infrared fine structure lines, regardless of their origin in the ionized or neutral phase of the interstellar medium. The Lfir/MH2 value where these line deficits start to manifest is similar to the limit that separates between the two modes of star formation recently found in galaxies on the basis of studies of their gas-star formation relations. Our finding that the properties of the interstellar medium are also significantly different in these regimes provides independent support for the different star forming relations in normal disk galaxies and major merger systems. We use the spectral synthesis code Cloudy to model the emission of the lines. The expected increase of the ionization parameter with Lfir/MH2 can simultaneously explain the line deficits in the [C II], [N II] and [O I] lines.

description: A previously developed field-theoretic model [R.D. Coalson et al., J. Chem. Phys. 102, 4584 (1995)] that treats core collisions and Coulomb interactions on the same footing is investigated in order to understand ion size effects on the partition of neutral and charged particles at planar interfaces and the ionic selectivity of slit nanopores. We introduce a variational scheme that can go beyond the mean-field (MF) regime and couple in a consistent way pore modified core interactions, steric effects, electrostatic solvation and image-charge forces, and surface charge induced electrostatic potential. We show that in the dilute limit, the MF and the variational theories agree well with MC simulation results, in contrast to a recent RPA method. The partition of charged Yukawa particles at a neutral dielectric interface (e.g air-water or protein-water interface) is investigated. It is shown that as a result of the competition between core collisions that push the ions towards the surface, and repulsive solvation and image forces that exclude them from the interface, a concentration peak of finite size ions sets in close to the dielectric interface. We also characterize the role played by the ion size on the ionic selectivity of neutral slit nanopores. We show that the complex interplay between electrostatic forces, excluded volume effects induced by core collisions and steric effects leads to an unexpected reversal in the ionic selectivity of the pore with varying pore size: while large pores exhibits a higher conductivity for large ions, narrow pores exclude large ions more efficiently than small ones.

Following airline mergers and network reorganizations aimed at reducing operational costs, consolidated air services at large hub airports have encouraged air travelers to forego use of their smaller local airports to access large hub airports offering superior air services farther away. This study investigates airport leakage in areas of Wisconsin and Michigan served by small airports, where air travelers may leak to neighboring large hubs. Using a proximity-based service area definition, three airports experiencing leakage are identified, and a hierarchical logit airport choice model is applied that accounts for air service characteristics and access distance for travelers coming from these airports’ service areas. Results show that a similar mean number of flight legs at both the local and substitute (large hub) airports will encourage leakage at Dane County Regional and Gerald R. Ford International airports, indicating that adding direct flights alone will not be sufficient to combat leakage. Comparable access distances to local and substitute airports have opposite effects on the local markets of Gerald R. Ford International and Milwaukee Mitchell International airports—promoting leakage at the former but discouraging it at the latter. Furthermore, proportional increases in airfares at local airports lead to uneven losses of markets in investigated service areas. Overall, the study provides empirical evidence of long-distance airport leakage in parts of the U.S. Midwest, and how its implications can be used by small airports seeking to further understand and respond to travelers’ airport choices within their local markets.

description: In public administration, more and more processes are being digitised and data is being used to collect information, determine the probability of events, or directly support the work of civil servants through automated decision-making. This practice offers many opportunities, but also raises a number of issues. The complexity and opacity of datasets, analysis processes, models or proprietary software creates black boxes in public management and calls for checks and balances. Possible harms inflicted through automated decision-making processes, infringement on privacy, autonomy, and the right to information need to be prevented; proportionality, function creep and the competence and capacity of city employees to adequately apply these novel methods are called into question. While there is a lively discourse emphasizing the need for ethics in AI and data practices, many of the available guidelines fall short in providing an applicable framework for responsible data practices. The Utrecht Data School has developed a deliberately dialogic and participatory approach to data ethics. In this paper we show how our tools enable dialogue between different participants in a data or AI project and give concrete examples of the use of our Data Ethics Decision Aid (DEDA) in municipal data and digitisation projects. We argue that participatory research practices for investigating datafication and algorithmization are very much connected to participatory data ethics.
C-Integrability Test for Discrete Equations via Multiple Scale Expansions

description: In this paper we are extending the well known integrability theorems obtained by multiple scale techniques to the case of linearizable difference equations. As an example we apply the theory to the case of a differential-difference dispersive equation of the Burgers hierarchy which via a discrete Hopf-Cole transformation reduces to a linear differential difference equation. In this case the equation satisfies the $A_1$, $A_2$ and $A_3$ linearizability conditions. We then consider its discretization. To get a dispersive equation we substitute the time derivative by its symmetric discretization. When we apply to this nonlinear partial difference equation the multiple scale expansion we find out that the lowest order non-secularity condition is given by a non-integrable nonlinear Schrödinger equation. Thus showing that this discretized Burgers equation is neither linearizable not integrable.

description: Laser-driven Plasma Accelerators (LPA) have successfully generated high energy, high charge electron bunches which can reach many kA peak current, over short distances. Space charge issues, even in transport lines as simple as a drift section, have to be carefully taken into account since they can degrade the beam quality, preventing any further application of such electron beams. We analyse the space charge effects within an electron bunch with numerical simulations in order to assess their effect on the beam. We use LPA beam parameters published in previous experimental studies. These studies can give an indication of the working point where space charge can dominate the beam dynamics and has to be taken into account in the application of such beams.

description: Understanding protein structure is of crucial importance in science, medicine and biotechnology. For about two decades, knowledge based potentials based on pairwise distances -- so-called "potentials of mean force" (PMFs) -- have been center stage in the prediction and design of protein structure and the simulation of protein folding. However, the validity, scope and limitations of these potentials are still vigorously debated and disputed, and the optimal choice of the reference state -- a necessary component of these potentials -- is an unsolved problem. PMFs are loosely justified by analogy to the reversible work theorem in statistical physics, or by a statistical argument based on a likelihood function. Both justifications are insightful but leave many questions unanswered. Here, we show for the first time that PMFs can be seen as approximations to quantities that do have a rigorous probabilistic justification: they naturally arise when probability distributions over different features of proteins need to be combined. We call these quantities reference ratio distributions deriving from the application of the reference ratio method. This new view is not only of theoretical relevance, but leads to many insights that are of direct practical use: the reference state is uniquely defined and does not require external physical insights; the approach can be generalized beyond pairwise distances to arbitrary features of protein structure; and it becomes clear for which purposes the use of these quantities is justified. We illustrate these insights with two applications, involving the radius of gyration and hydrogen bonding. In the latter case, we also show how the reference ratio method can be iteratively applied to sculpt an energy funnel. Our results considerably increase the understanding and scope of energy functions derived from known biomolecular structures.

Derivation of the Gauge Link in Light Cone Gauge

Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In light cone gauge, a gauge link at light cone infinity is necessary for transverse momentum-dependent parton distribution to restore the gauge invariance in some specific boundary conditions. We derive such transverse gauge link in a more regular and general method. We find the gauge link at light cone infinity naturally arises from the contribution of the pinched poles: one is from the quark propagator and the other is hidden in the gauge vector field in light cone gauge. Actually, in the amplitude level, we have obtained a more general gauge link over the hypersurface at light cone infinity which is beyond the transverse direction. The difference of such gauge link between semi-inclusive deep inelastic scattering and Drell-Yan processes can also be obtained directly and clearly in our derivation.

description: We have conducted a theoretical study of harmonic generation from a silver grating having slits filled with GaAs. By working in the enhanced transmission regime, and by exploiting phase-locking between the pump and its harmonics, we guarantee strong field localization and enhanced harmonic generation under conditions of high absorption at visible and UV wavelengths. Silver is treated using the hydrodynamic model, which includes Coulomb and Lorentz forces, convection, electron gas pressure, plus bulk X(3) contributions. For GaAs we use nonlinear Lorentz oscillators, with characteristic X(2) and X(3) and nonlinear sources that arise from symmetry breaking and Lorentz forces. We find that: (i) electron pressure in the metal contributes to linear and nonlinear processes by shifting/reshaping the band structure; (ii) TEand TM-polarized harmonics can be generated efficiently; (iii) the X(2) tensor of GaAs couples TE- and TM-polarized harmonics that create phase-locked pump photons having polarization orthogonal compared to incident pump photons; (iv) Fabry-Perot resonances yield more efficient harmonic generation compared to plasmonic transmission peaks, where most of the light propagates along external metal surfaces with little penetration inside its volume. We predict conversion efficiencies that range from 10-6 for second harmonic generation to 10-3 for the third harmonic signal, when pump power is 2GW/cm2.

description: A culturally competent survey currently does not exist to characterize the burden of Adverse Childhood Experiences (ACEs) among a HIV/AIDS population receiving care at a local Center of Excellence (COE). A qualitative study was conducted including 11 interviews involving opinions on national surveillance questions to develop a culturally competent survey. Purposive sampling, reactive probing, and analysis of transcribed interviews were completed using structured coding to determine which questions were kept, modified, or removed​ in the final survey. The final 55-question survey contained more generalized ACE questions, topics pertaining to barriers to HIV care, and a list that patients could select from to indicate what they need to improve their HIV care. The final survey provided the opportunity to characterize the burden of ACEs at a COE. Future directions involve piloting the survey as a quality improvement tool with the goal of increasing retention rates through more individualized HIV care.

description: Im Rahmen der voranschreitenden Digitalisierung von Arbeitswelten und der vielfachen Implementierung von modernen Informationssystemen ist die Frage nach wirkungsvollen Innovationslösungen nicht nur für Praktiker, sondern auch für Systementwickler von fundamentaler Bedeutung. Die Forschung rund um das Thema Gamification ist in den letzten Jahren stark gewachsen und gewann an Popularität in verschiedensten Bereichen, wie beispielsweise in der Arbeitswelt, im Bildungs- oder Gesundheitswesen. Spiel-Design-Elemente wurden entwickelt und werden als vielversprechendes Mittel angesehen, um das Mitarbeiter- oder Kundenverhalten möglichst positiv zu beeinflussen. Über die Wirkung der Spiel-Design-Elemente auf die spielerische Erfahrung des Mitarbeiters ist allerdings noch wenig bekannt. Daher liefern wir mit einer kürzlich durchgeführten Studie erste Erklärungsansätze zu den Wirkungszusammenhängen zwischen den Spiel-Design-Elementen Belohnung, Selbstdarstellung und sozialer Zusammenhalt in Bezug auf das mehrdimensionale Konstrukt der spielerischen Erfahrung. Die erste empirische Analyse von 405 befragten MitarbeiternInnen lässt vermuten, dass sowohl Belohnungselemente als auch die Möglichkeit der Selbstdarstellung und der soziale Zusammenhalt durch Kooperationsmöglichkeiten im Team in einem gamifizierten Informationssystem einen signifikanten positiven Einfluss auf die spielerische Erfahrung des Anwenders nehmen. Zusammenfassend leisten wir einen Beitrag zur Gamification-Forschung, indem wir das Konstrukt der spielerischen Erfahrung am Arbeitsplatz durch verschiedene Antezedens weiter durchdringen. Unsere Ergebnisse helfen bei der praktischen Ausgestaltung von gamifizierten Systemen am Arbeitsplatz und ermöglichen zielgerichtete Handlungs-empfehlungen für das Management und für Systementwickler in Bezug auf die aktuelle Gestaltung sowie auf zukünftige Einführungsmöglichkeiten von zielführenden Spiel-Design-Elementen.

description: Although the automation of cars aims to facilitate driving, current systems still rely on the driver for handling critical driving situations. As long as fully automatic systems are not available, the driver has to be supported in the take-over maneuver. We thus propose an interface that relies on auditory and visual signals to support the take-over process. Our interface further provides assistance for driving in poor visibility conditions, such as bad weather or darkness, by highlighting other traffic participants and lane boundaries. An online evaluation of our interface with 22 participants indicates a good usability, user experience, and acceptance.

description: Gradient catastrophe and flutter instability in the motion of vortex filament within the localized induction approximation are analyzed. It is shown that the origin if this phenomenon is in the gradient catastrophe for the dispersionless Da Rios system which describes motion of filament with slow varying curvature and torsion. Geometrically this catastrophe manifests as a rapid oscillation of a filament curve in a point that resembles the flutter of airfoils. Analytically it is the elliptic umbilic singularity in the terminology of the catastrophe theory. It is demonstrated that its double scaling regularization is governed by the Painlevé-I equation.

description: In this paper, the cosmological dynamics of Brans-Dicke theory in which there are fermions with a coupling to BD scalar field as well as a self-interaction potential is investigated. The conditions that there exists a solution which is stable and represents a late-time accelerated expansion of the universe are found. The variable mass of fermions can not vanish exactly during the evolution of the universe once it exists initially. It is shown that the late-time acceleration depends completely on the self-interaction of the fermionic field if our investigation is restricted to the theory with positive BD parameter $ω$. Provided a negative $ω$ is allowed, there will be another two class of stable solutions describing late-time accelerated expansion of the universe.

description: The application of machine learning (ML) in the medical domain has recently received a lot of attention. However, the constantly growing need for data in such ML-based approaches raises many privacy concerns, particularly when data originate from vulnerable groups, for example, people with a rare disease. In this context, a challenging but promising approach is the design of privacy-preserving computation technologies (e.g. differential privacy). However, design guidance on how to implement such approaches in practice has been lacking. In our research, we explore these challenges in the design process by involving stakeholders from medicine, security, ML, and human-computer interaction, as well as patients themselves. We emphasize the suitability of reflective design in this context by considering the concept of privacy by design. Based on a real-world use case situated in the healthcare domain, we explore the existing privacy needs of our main stakeholders, i.e. medical researchers or physicians and patients. Stakeholder needs are illustrated within two scenarios that help us to reflect on contradictory privacy needs. This reflection process informs conceptional design rationales and our proposal for privacy-preserving explanation user interfaces. We propose that the latter support both patients’ privacy preferences for a meaningful data donation and experts’ understanding of the privacy-preserving computation technology employed.

description: A framework is developed which quantifies the local exchange of energy and momentum between matter and the linearized gravitational field. We derive the unique gravitational energy-momentum tensor consistent with this description, and find that this tensor only exists in the harmonic gauge. Consequently, nearly all the gauge freedom of our framework is naturally and unavoidably removed. The gravitational energy-momentum tensor is then shown to have two exceptional properties: (a) it is gauge-invariant for gravitational plane-waves, (b) for arbitrary transverse-traceless fields, the energy-density is never negative, and the energy-flux is never spacelike. We analyse in detail the local gauge invariant energy-momentum transferred between the gravitational field and an infinitesimal point-source, and show that these invariants depend only on the transverse-traceless components of the field. As a result, we are led to a natural gauge-fixing program which at last renders the energy-momentum of the linear gravitational field completely unambiguous, and additionally ensures that gravitational energy is never negative nor flows faster than light. Finally, we calculate the energy-momentum content of gravitational plane-waves, the linearized Schwarzschild spacetime (extending to arbitrary static linear spacetimes) and the gravitational radiation outside two compact sources: a vibrating rod, and an equal-mass binary.

description: The interference between coherent and squeezed vacuum light can produce path entangled states with very high fidelities. We show that the phase sensitivity of the above interferometric scheme with parity detection saturates the quantum Cramer-Rao bound, which reaches the Heisenberg-limit when the coherent and squeezed vacuum light are mixed in roughly equal proportions. For the same interferometric scheme, we draw a detailed comparison between parity detection and a symmetric-logarithmic-derivative-based detection scheme suggested by Ono and Hofmann.

description: A culturally competent survey currently does not exist to characterize the burden of Adverse Childhood Experiences (ACEs) among a HIV/AIDS population receiving care at a local Center of Excellence (COE). A qualitative study was conducted including 11 interviews involving opinions on national surveillance questions to develop a culturally competent survey. Purposive sampling, reactive probing, and analysis of transcribed interviews were completed using structured coding to determine which questions were kept, modified, or removed​ in the final survey. The final 55-question survey contained more generalized ACE questions, topics pertaining to barriers to HIV care, and a list that patients could select from to indicate what they need to improve their HIV care. The final survey provided the opportunity to characterize the burden of ACEs at a COE. Future directions involve piloting the survey as a quality improvement tool with the goal of increasing retention rates through more individualized HIV care.

description: The sunspot penumbra is a transition zone between the strong vertical magnetic field area (sunspot umbra) and the quiet Sun. The penumbra has a fine filamentary structure that is characterized by magnetic field lines inclined toward the surface. Numerical simulations of solar convection in inclined magnetic field regions have provided an explanation of the filamentary structure and the Evershed outflow in the penumbra. In this paper, we use radiative MHD simulations to investigate the influence of the magnetic field inclination on the power spectrum of vertical velocity oscillations. The results reveal a strong shift of the resonance mode peaks to higher frequencies in the case of a highly inclined magnetic field. The frequency shift for the inclined field is significantly greater than that in vertical field regions of similar strength. This is consistent with the behavior of fast MHD waves.

Contributions of intrinsic and environmental factors to early life DNA methylation
Creators: name: Goodman, Sarah Jessica
Publisher: name: University of British Columbia

description: Many early experiences and exposures are known to cause health disparities later in life, suggesting that they are somehow ‘biologically embedded’. The mechanisms underlying ‘biological embedding’ are currently not well understood. However, emerging evidence has implicated a potential contribution from epigenetic modifications, such as DNA methylation (DNAm), which has been shown to associate with early life experiences of low socioeconomic status. Additional related experiences have also been connected with DNAm, including parental stress, childhood maltreatment or deprivation, and maternal mental health problems during the perinatal period. The relationship between early life experience and epigenetics is complicated by internal psychological and physiological factors, as well as genetic variation, which can account for 20% to 80% of inter-individual epigenetic differences. As well, stress reactivity and temperament are predictive of how a child may interact with his or her environment and can affect how such exposures are internalized. Thus, the main objectives of my dissertation were to elucidate the relationships between childhood environment, DNAm, genetic variation, and behaviour, to understand how these systems influence one another. Using matched DNAm profiles from blood and buccal tissue from a cross-sectional cohort of Canadian children, I uncovered tissue-specific and -shared DNAm signatures in order to glean the utility of accessible tissues in epigenetic association studies. In a longitudinal cohort, I tested the hypothesis that indicators of children’s early internal, biological and behavioural responses to stressful challenges are linked to stable patterns of DNAm later in life; I found relationships between biobehavioural response propensities in early life and patterns of DNAm in DLX5 and IGF2 genes at ages 15 and 18. Finally, I examined the epigenetic correlates of familial socioeconomic status in matched childhood peripheral blood and dried neonatal blood spot samples, allowing me to assess the DNAm pattern over time. Together these findings build upon our current understanding of the role of DNAm in biological embedding and more broadly, the field of social epigenetics.

description: Many Germans perceive a brutalization of society, and state officials also report feeling under attack. At the same time, policing is criticised for becoming increasingly militarised and for having extended surveillance in the course of fighting terrorism. Advancements in HCI are used in the context of many of the issues that policing is facing. In this study, we conduct a representative survey of the German population to investigate personal experiences with and attitudes towards the police and information and communication technologies (ICT) used for policing. We find an overall positive image of the police and uncritical attitudes towards ICT used for general surveillance (body-worn cameras, video surveillance, face recognition) and slightly more critical attitudes towards personal surveillance (e.g. through communication data retention). The study indicates that perceptions differ according to experience of unfair treatment by the police, while other factors such as age and education have similar effects.
