description: In this paper, we study the perturbative aspects of a twisted version of the two-dimensional $(0,2)$ heterotic sigma model on a holomorphic gauge bundle $\mathcal E$ over a complex, hermitian manifold $X$. We show that the model can be naturally described in terms of the mathematical theory of ``Chiral Differential Operators". In particular, the physical anomalies of the sigma model can be reinterpreted in terms of an obstruction to a global definition of the associated sheaf of vertex superalgebras derived from the free conformal field theory describing the model locally on $X$. One can also obtain a novel understanding of the sigma model one-loop beta function solely in terms of holomorphic data. At the $(2,2)$ locus, where the obstruction vanishes for $\it{any}$ smooth manifold $X$, we obtain a purely mathematical description of the half-twisted variant of the topological A-model and (if $c_1(X) =0$) its elliptic genus. By studying the half-twisted $(2,2)$ model on $X=\mathbb {CP}^1$, one can show that a subset of the infinite-dimensional space of physical operators generates an underlying super-affine Lie algebra. Furthermore, on a non-Kähler, parallelised, group manifold with torsion, we uncover a direct relationship between the modulus of the corresponding sheaves of chiral de Rham complex, and the level of the underlying WZW theory.

description: We report the magnetic confinement of neutral, ground state hydroxyl radicals (OH) at a density of $\sim3\times10^{3}$ cm$^{-3}$ and temperature of $\sim$30 mK. An adjustable electric field of sufficient magnitude to polarize the OH is superimposed on the trap in either a quadrupole or homogenous field geometry. The OH is confined by an overall potential established via molecular state mixing induced by the combined electric and magnetic fields acting on the molecule's electric dipole and magnetic dipole moments, respectively. An effective molecular Hamiltonian including Stark and Zeeman terms has been constructed to describe single molecule dynamics inside the trap. Monte Carlo simulation using this Hamiltonian accurately models the observed trap dynamics in various trap configurations. Confinement of cold polar molecules in a magnetic trap, leaving large, adjustable electric fields for control, is an important step towards the study of low energy dipole-dipole collisions.

description: Humanitarian aid alleviates suffering and save lives affected by crisis. Impact evaluations, considered as researching interventions' contribution to changes in affected people's health, are increasingly debated to ensure effectiveness and raise quality of aid projects.

High quality impact research requires (1) robust methods, e.g. control group to measure attributable change and (2) embedding of results, e.g. discussing ethical issues and study limitations. To contribute to the ongoing theoretical debate from a practical perspective we systematically analysed the existing literature on humanitarian aid for existing evidence from international non governmental organisations’ aid impact on health of populations affected by humanitarian crisis.Civil Society Organizations (CSOs) conducting humanitarian assistance rarely report on impact of their programmes. Studies on humanitarian programmes presented in the academic literature lack robust methods to conclude impact. More collaboration between humanitarian sector and academics is needed to address the lack of humanitarian aid impact measurements.

description: Despite high dengue endemicity in Léogâne (Haiti), anecdotal evidence suggested that awareness and understanding of the disease and its burden was low amongst MSF national staff and the general community and this was thought to be one reason for the limited public health efforts to combat dengue in Léogâne. An understanding of local perceptions could inform MSF plans to help tackle dengue in the area. A study involving qualitative and quantitative methods was undertaken to explore the conceptual dimensions of dengue “invisibility” among health workers and community and members’ perceptions of and responses to febrile illnesses in a location that has experienced recent major disease outbreaks.Besides the results above, this study also showed that community and health workers’ responses to a dengue outbreak, in the context of previous major disease outbreaks, mobilised a far more complex set of anthropological parameters than just “traditional culture”, such as past epidemic social history, local and global political and geopolitical relations. Health promotion interventions would benefit from understanding and integrating these parameters that impact on health system response and health-seeking behaviour. BRAMU intends to develop rapid anthropologic guidelines for interventions in epidemic settings as a mid-term impact of this study.

description: We present a low-resolution spectroscopic survey of the Orion nebula which data we release for public use. In this article, we intend to show the possible applications of this dataset analyzing some of the main properties of the nebula. We perform an integral field spectroscopy mosaic of an area of ~5' X 6' centered on the Trapezium region of the nebula, including the ionization front to the south-east. The analysis of the line fluxes and line ratios of both the individual and integrated spectra allowed us to determine the main characteristics of the ionization throughtout the nebula.The final dataset comprises 8182 individual spectra, which sample each one a circular area of \~2.7" diameter. The data can be downloaded as a single row-stacked spectra fits file plus a position table or as an interpolated datacube with a final sampling of 1.5"/pixel. The integrated spectrum across the field-of-view was used to obtain the main integrated properties of the nebula, including the electron density and temperature, the dust extinction, the Halpha integrated flux (after correcting for dust reddening), and the main diagnostic line ratios. The individual spectra were used to obtain line intensity maps of the different detected lines. These maps were used to study the distribution of the ionized hydrogen, the dust extinction, the electron density and temperature, and the helium and oxygen abundance...

description: Visceral leishmaniasis (VL), also known as Kala azar, is  considered one of the most important neglected tropical diseases. Although globally distributed, India holds 50% of the world´s burden, and within it, 80% corresponds to Bihar state, in the north of the country. In this context, Médecins Sans Frontières (MSFOCBA) opened a project in 2007 in a rural secondary hospital in Hajipur, Bihar, covering also five of the primary health centres in hyper endemic pockets. 

The recent data of HIV infection in this part of the country is considered to be around 0.4%. It is known that HIV and VL coinfection affects the course of both diseases; it is associated with higher mortality, lower clinical cure rates, frequent VL relapses and increased side effects of medication. However, the association with other common and chronic diseases as diabetes mellitus (DM) is unknown. We present a VL-HIV co-infected patient with uncontrolled DM and multiple VL relapses who attended our hospital.Although immunosuppression is a well known risk factor for developing this disease, the relation between uncontrolled DM in VL is unknown and it might represent a risk factor for VL relapse. The prevalence of diabetes among adults in India has reached 20% in some areas and is expected to increase in coming years. Further studies are and will be required to understand the potential link between DM and VL and the adequate treatment and prophylaxis for these patients.

description: In this note, we summarize and compare various model predictions for $pp$ total cross-section $σ_{\rm tot}^{pp}$, giving an estimate of the range of predictions for the total cross-section, $σ_{\rm tot}^{pp}$ expected at the LHC. We concentrate on the results for $σ_{\tot}^{pp}$ obtained in a particular QCD based model of the energy dependence of the total cross-section, including the effect of soft gluon radiation. We obtain the range of predictions in this model by exploring the allowed range of model parameters. We further give a handy parametrisation of these results which incidentally spans the range of various other available predictions at the LHC as well.

A sliding wear model and its application to heat exchanger tube wear
Creators: name: Chen, JingPing
Publisher: name: University of British Columbia
Year: 2009

description: The objective of this study is to quantitatively determine wear and its main parameter relationships for heat exchanger tube wear. A model has been proposed. The literature of the current state of heat exchanger tube wear study, wear mechanisms, and wear models were reviewed. Tube/disc sliding wear tests were conducted with an impact-fretting testing rig incorporated with an advanced control system and an accurate data acquisition system. These ensured that the test results are reliable. The relationships between wear and normal load, wear and sliding distance, wear and frictional work were determined. Advanced surface analysis techniques were used to better understand the heat exchanger tube wear problem. It was found that the roughness and its standard deviation of the tube and the disc were much the same after wear, but surface roughness was neither directly related to the sliding distance nor to the normal load. Plastic deformation was observed. Oxidation became an important mechanism for carbon steel disc/Incoloy tube combination even at room temperature. Based on the experimental results obtained, it was found that the dynamic model by Lin and Cheng was quite suitable for the heat exchanger tube wear. The calculated results satisfactorily matched the test results. This model has been extented to calculate tube wear depth.

description: We present a method of measuring the quantum state of a harmonic oscillator through instantaneous probe-system selective interactions of the Jaynes-Cummings type. We prove that this scheme is robust to general decoherence mechanisms, allowing the possibility of measuring fast-decaying systems in the weak-coupling regime. This method could be applied to different setups: motional states of trapped ions, microwave fields in cavity/circuit QED, and even intra-cavity optical fields.

description: In complex scale-free networks, ranking the individual nodes based upon their importance has useful applications, such as the identification of hubs for epidemic control, or bottlenecks for controlling traffic congestion. However, in most real situations, only limited sub-structures of entire networks are available, and therefore the reliability of the order relationships in sampled networks requires investigation. With a set of randomly sampled nodes from the underlying original networks, we rank individual nodes by three centrality measures: degree, betweenness, and closeness. The higher-ranking nodes from the sampled networks provide a relatively better characterisation of their ranks in the original networks than the lower-ranking nodes. A closeness-based order relationship is more reliable than any other quantity, due to the global nature of the closeness measure. In addition, we show that if access to hubs is limited during the sampling process, an increase in the sampling fraction can in fact decrease the sampling accuracy. Finally, an estimation method for assessing sampling accuracy is suggested.

Slender ship procedures that include the effects of yaw, vortex shedding and density stratification
Creators: name: Wong, Haw L.
Publisher: name: University of British Columbia
Year: 2009

description: The accurate determination of hydrodynamic loads on moving ships is important for hull form design and optimization and structural design purposes. This is especially true at the preliminary design stage during which time quick predictions of the forces and moments acting on a ship advancing steadily with, and without, yaw would be extremely useful. In view of this, simple numerical cross-flow algorithms has been developed. The numerical procedures are based on slender body theory, which is used to convert the three dimensional problem into a series of two dimensional wavemaker problems in the plane of transverse sections, marching in small steps from the bow section towards the stem. Fluid density stratification, vortex shedding, finite water depth and nonlinear free surface effects can be allowed for in the algorithms. A procedure for handling density stratified flow has been developed and successfully used for the calculation of surface and interfacial waves created by a prolate spheroid. Vortex shedding is modelled using the discrete vortex method. A hybridization of the discrete vortex and boundary element methods is achieved and illustrated in a test case of predicting the forces acting on an oscillating flat plate. The wavemaker, with the fully nonlinear free surface conditions, is used for calculating the generated wave pattern and wavemaking resistance of a Wigley hull. The effects of finite water depth on wavemaking resistance are calculated. The hybrid boundary element-discrete vortex method is used for determining the hydrodynamic forces and moments acting on a yawed Wigley hull.

description: Continuous distance-based outlier detection in streaming data is one of the most important aspects on data science and analytics. Thus far there is not a research paper combining the outlier detection algorithms with a parallel streaming environment. This research tackles this problem and starts off by describing the basic background material needed for a complete understanding of streaming semantics and the distance-based outlier detection algorithms. It continuous with the introduction of a baseline single-partition algorithm on a stream of data and the parallelization of that algorithm with data replication on each partition. The parallel algorithm is updated with two extensions. The first extension is the use of a data structure to support fast range queries and the second is a different type of data partitioning. The last algorithm presented is a variation of MCOD. Finally the results of the experiments are presented. This work ends with a report on related work, research conclusions and possible future work.

Συγκεκριμένα εξετάζεται πώς μέσα από τις δύο αφηγήσεις αναδεικνύονται ζητήματα όπως: ο χαρακτήρας του καλλιτέχνη, η ρεαλιστική μίμηση, τα όρια της τέχνης, η σχέση του καλλιτέχνη με τους θεούς και η ψευδαίσθηση που προκαλούν τα ρεαλιστικά έργα στους θεατές.
description: The Metamorphoses is a work in many of its episodes the protagonists are artists. In some of these episodes Ovid deals with one of his favorite subjects: the relation between nature and art. The present thesis examines the multifaceted dimensions of this subject in two narrations that revolve mostly around of this subject and have remarkable similarities and differences: it’s about the Daedalus (8.152-168, 183-262) and the Pygmalion (10.243-297) episode. In particular the study examines the way in which emerge through these narrations issues such as the character of the artist, the mimesis, the limits of art, the relation of the artist with the gods and the illusion that create the realistic works of art on the spectators.

description: We explore the role of Mo in Fe:Mo nanocatalyst thermodynamics for low-temperature chemical vapor deposition growth of single walled carbon nanotubes (SWCNTs). By using the size-pressure approximation and ab initio modeling, we prove that for both Fe-rich (~80% Fe or more) and Mo-rich (~50% Mo or more) Fe:Mo clusters, the presence of carbon in the cluster causes nucleation of Mo2C. This enhances the activity of the particle since it releases Fe, which is initially bound in a stable Fe:Mo phase, so that it can catalyze SWCNT growth. Furthermore, the presence of small concentrations of Mo reduce the lower size limit of low-temperature steady-state growth from ~0.58nm for pure Fe particles to ~0.52nm. Our ab initio-thermodynamic modeling explains experimental results and establishes a new direction to search for better catalysts.

description: We have undertaken the simulation of hydrodynamic flows with bulk Lorentz factors in the range 10^2--10^6. We discuss the application of an existing relativistic, hydrodynamic primitive-variable recovery algorithm to a study of pulsar winds, and, in particular, the refinement made to admit such ultra-relativistic flows. We show that an iterative quartic root finder breaks down for Lorentz factors above 10^2 and employ an analytic root finder as a solution. We find that the former, which is known to be robust for Lorentz factors up to at least 50, offers a 24% speed advantage. We demonstrate the existence of a simple diagnostic allowing for a hybrid primitives recovery algorithm that includes an automatic, real-time toggle between the iterative and analytical methods. We further determine the accuracy of the iterative and hybrid algorithms for a comprehensive selection of input parameters and demonstrate the latter's capability to elucidate the internal structure of ultra-relativistic plasmas. In particular, we discuss simulations showing that the interaction of a light, ultra-relativistic pulsar wind with a slow, dense ambient medium can give rise to asymmetry reminiscent of the Guitar nebula leading to the formation of a relativistic backflow harboring a series of internal shockwaves. The shockwaves provide thermalized energy that is available for the continued inflation of the PWN bubble. In turn, the bubble enhances the asymmetry, thereby providing positive feedback to the backflow.

description: Proteins are polymers of amino acids. These macromolecules are synthesized by intracellular machines called ribosomes. Although the experimental investigation of protein synthesis has been a traditional area of research in molecular cell biology, important quantitative models of protein synthesis have been reported in research journals devoted to statistical physics and related interdisciplinary topics. From the perspective of a physicist, protein synthesis is the classical transport of interacting ribosomes on a messenger RNA (mRNA) template that dictates the sequence of the amino acids on the protein. We discuss appropriate simplification of the models and methods. In particular, we develop and analyze a simple toy model using some elementary techniques of non-equilibrium statistical mechanics and predict the average rate of protein synthesis and the spatial organization of the ribosomes in the steady state.

description: We perform a detailed analysis of one-loop corrections to the self-energy of the (off-shell) gauge bosons in six-dimensional N=1 supersymmetric gauge theories on orbifolds. After discussing the Abelian case in the standard Feynman diagram approach, we extend the analysis to the non-Abelian case by employing the method of an orbifold-compatible one-loop effective action for a classical background gauge field. We find that bulk higher derivative and brane-localised gauge kinetic terms are required to cancel one-loop divergences of the gauge boson self energy. After their renormalisation we study the momentum dependence of both the higher derivative coupling h(k^2) and the {\it effective} gauge coupling g_eff(k^2). For momenta smaller than the compactification scales, we obtain the 4D logarithmic running of g_eff(k^2), with suppressed power-like corrections, while the higher derivative coupling is constant. We present in detail the threshold corrections to the low energy gauge coupling, due to the massive bulk modes. At momentum scales above the compactification scales, the higher derivative operator becomes important and leads to a power-like running of g_eff(k^2) with respect to the momentum scale. The coefficient of this running is at all scales equal to the renormalised coupling of the higher derivative operator which ensures the quantum consistency of the model. We discuss the relation to the similar one-loop correction in the heterotic string, to show that the higher derivative operators are relevant in that case too, since the field theory limit of the one-loop string correction does not commute with the infrared regularisation of the (on-shell) string result.

description: Using computer simulations of over 100,000 atoms, the mechanism for the hydrophobic collapse of an idealized hydrated chain is obtained. This is done by coarse-graining the atomistic water molecule positions over 129,000 collective variables that represent the water density field and then using the string method in these variables to compute the minimum free energy pathway (MFEP) for the collapsing chain. The dynamical relevance of the MFEP (i.e. its coincidence with the mechanism of collapse) is validated a posteriori using conventional molecular dynamics trajectories. Analysis of the MFEP provides atomistic confirmation for the mechanism of hydrophobic collapse proposed by ten Wolde and Chandler. In particular, it is shown that lengthscale-dependent hydrophobic dewetting is the rate-limiting step in the hydrophobic collapse of the considered chain.

description: We present a QCD calculation of the coherent multiple scattering effect on single hadron production in semi-inclusive lepton-nucleus deep inelastic scattering (DIS). We show that the destructive interference of coherent multiple scattering leads to suppression in hadron productions. The suppression is similar to the expectations of energy loss calculations. We compare our calculation with experimental data.

description: Context. The CoRoT mission, a pioneer in exoplanet searches from space, has completed its first 150 days of continuous observations of ~12000 stars in the galactic plane. An analysis of the raw data identifies the most promising candidates and triggers the ground-based follow-up. Aims. We report on the discovery of the transiting planet CoRoT-Exo-2b, with a period of 1.743 days, and characterize its main parameters. Methods. We filter the CoRoT raw light curve of cosmic impacts, orbital residuals, and low frequency signals from the star. The folded light curve of 78 transits is fitted to a model to obtain the main parameters. Radial velocity data obtained with the SOPHIE, CORALIE and HARPS spectro-graphs are combined to characterize the system. The 2.5 min binned phase-folded light curve is affected by the effect of sucessive occultations of stellar active regions by the planet, and the dispersion in the out of transit part reaches a level of 1.09x10-4 in flux units. Results. We derive a radius for the planet of 1.465+-0.029 R_Jup and a mass of 3.31+-0.16 M_Jup, corresponding to a density of 1.31+-0.04 g/cm^3. The large radius of CoRoT-Exo-2b cannot be explained by current models of evolution of irradiated planets.

description: We propose new algorithms for the computation of the first N terms of a vector (resp. a basis) of power series solutions of a linear system of differential equations at an ordinary point, using a number of arithmetic operations which is quasi-linear with respect to N. Similar results are also given in the non-linear case. This extends previous results obtained by Brent and Kung for scalar differential equations of order one and two.

description: The aim of the present paper is to investigate the half-spaces in the convexity structure of all quasiorders on a given set and to use them in an alternative approach to classical order dimension. The main result states that linear orders can almost always be replaced by half-space quasiorders in the definition of the dimension of a partially ordered set.

description: We analyze properties of a map B = f(U) sending a unitary matrix U of size N into a doubly stochastic matrix defined by B_{i,j} = |U_{i,j}|^2. For any U we define its DEFECT, determined by the dimensionality of the space being the image Df(T_U Unitaries) of the space T_U Unitaries tangent to the manifold of unitary matrices Unitaries at U, under the tangent map Df corresponding to f. The defect, equal to zero for a generic unitary matrix, gives an upper bound for the dimensionality of a smooth orbit (a manifold) of inequivalent unitary matrices V mapped into the same image, f(V) = f(U) = B, stemming from U. We demonstrate several properties of the defect and prove an explicit formula for the defect of a Fourier matrix F_N of size N. In this way we obtain an upper bound for the dimensionality of a smooth orbit of inequivalent unitary complex Hadamard matrices stemming from F_N. It is equal to zero iff N is prime and coincides with the dimensionality of the known orbits if N is a power of a prime. Two constructions of these orbits are presented at the end of this work.

Master singular behavior for the Sugden factor of the one-component fluids near their gas-liquid critical point

description: We present the master (i.e. unique) behavior of the squared capillary length - so called the Sudgen factor-, as a function of the temperature-like field along the critical isochore, asymptotically close to the gas-liquid critical point of twenty (one component) fluids. This master behavior is obtained using the scale dilatation of the relevant physical fields of the one-component fluids. The scale dilatation introduces the fluid-dependent scale factors in a manner analog with the linear relations between physical fields and scaling fields needed by the renormalization theory applied to the Ising-like universality class. The master behavior for the Sudgen factor satisfies hyperscaling and can be asymptotically fitted by the leading terms of the theoretical crossover functions for the correlation length and the susceptibility in the homogeneous domain recently obtained from massive renormalization in field theory. In the absence of corresponding estimation of the theoretical crossover functions for the interfacial tension, we define the range of the temperature-like field where the master leading power law can be practically used to predict the singular behavior of the Sudgen factor in conformity with the theoretical description provided by the massive renormalization scheme within the extended asymptotic domain of the one-component fluid "subclass".
Turbulent natural convestion boundary layers in an absorbing and emitting gas
Creators: name: Shabany, Younes Sh. G.
Publisher: name: University of British Columbia
Year: 2009

description: Turbulent natural convection boundary layers along a vertical flat plate were numerically simulated for non-absorbing and absorbing gases. By varying the value of absorption coefficient of the gas, the effects of radiative heat transfer on the velocity and temperature profiles of the boundary layer were investigated. A broad range of absorption coefficients, including very high and very low values, were covered. Three different turbulence models were used to predict the mean characteristics of the turbulent natural convection boundary layer in a non-absorbing gas: the algebraic mixing length model proposed by Cebeci and Khattab; the low-Reynolds-number k-e models of Jones and Launder, and To and Humphrey. It was observed that the Jones and Launder model would predict a later transition if the grids in the flow direction were more refined. However, when the wall functions and extra source terms in the k and e equations were applied only before the point of maximum velocity, this deficiency was removed. The model in this case was called modified Jones and Launder model. A comparison between the calculated results and the experimental data of Tsuji and Nagana showed that the modified Jones and Launder model was able to predict fairly well the natural convection boundary layer. Turbulent natural convection boundary layers in an absorbing and emitting gas were then calculated using the modified Jones and Launder turbulence model. The calculations were done for two wall temperatures; Tw = 60°C and Tw = 200°C with T⍵ = 25°C for both cases. It was observed that as the absorption coefficient of the gas increased, velocities and temperatures in the inner region of boundary layer increased, but turbulent viscosities decreased. The convective heat transfer rate also decreased. However, this trend reversed at some value of absorption coefficient. It was shown that there was a relation between the range of influence of radiation, compared to the boundary layer thickness, and the type of behavior mentioned above. A comparison between the results for different wall temperatures revealed that, for the limiting cases of optically thin and optically thick gas, the normalized velocity profile ur, and normalized temperature profile tr, were independent of temperature difference between the wall and the medium at a specified Rayleigh number. The convective component of the Nusselt number became a function only of Rayleigh number. For the case of an optically intermediate gas a dependence on wall to gas temperature difference was noted.

description: We study tunneling of electrons into and between interacting wires in the spin-incoherent regime subject to a magnetic field. The tunneling currents follow power laws of the applied voltage with exponents that depend on whether the electron spins at the relevant length scales are polarized or disordered. The crossover length (or energy) scale is exponential in the applied field. In a finite size wire multiple crossovers can occur.
