description: An analysis of the NICMOS Deep Field shows that there is no evidence of a decline in the bar fraction beyond z~0.7, as previously claimed; both bandshifting and spatial resolution must be taken into account when evaluating the evolution of the bar fraction. Two main caveats of this study were a lack of a proper comparison sample at low redshifts and a larger number of galaxies at high redshifts. We address these caveats using two new studies. For a proper local sample, we have analyzed 134 spirals in the near-infrared using 2MASS (main results presented by Menendez-Delmestre in this volume) which serves as an ideal anchor for the low-redshift Universe. In addition to measuring the mean bar properties, we find that bar size is correlated with galaxy size and brightness, but the bar ellipticity is not correlated with these galaxy properties. The bar length is not correlated with the bar ellipticity. For larger high redshift samples we analyze the bar fraction from the 2-square degree COSMOS ACS survey. We find that the bar fraction at z~0.7 is ~50%, consistent with our earlier finding of no decline in bar fraction at high redshifts.

description: Strangeness canonical ensemble for Maxwell-Boltzmann statistics is reconsidered for excited nuclear systems with non-vanishing net strangeness. A new recurrence relation method is applied to find the partition function. The method is first generalized to the case of quantum strangeness canonical ensemble. Uncertainties in calculation of the K+/pi+ excitation function are discussed. A new scenario based on the strangeness distillation effect is put forward for a possible explanation of anomalous strangeness production observed at the bombarding energy near 30 AGeV. The peaked maximum in the K+/pi+ ratio is considered as a sign of the critical end-point reached in evolution of the system rather than a latent heat jump emerging from the onset of the first order deconfinement phase transition.

description: Die Wirkung, die Märkte auf ihre Umgebung haben, versinnbildlicht nicht nur deren Bedeutung als eine Institution des sozialen Lebens und als ein Ort, an dem sich die städtische Bevölkerung versammelt und zusammenlebt, sondern auch als ein Katalysator für positive Entwicklung der Stadtmorphologie in inhaltsarmen Vierteln. Traditionelle Märkte werden als Teil des kulturellen Erbes von Zagreb gesehen und als Symbol einer anhaltenden Tradition, obwohl sie sich verringern und durch notdürftige und verspätete Sanierungen, Umzüge und fehlende Infrastruktur ihre Identität verlieren. Getroffen von diskriminierenden Richtlinien, unklaren offiziellen Regeln und hohen Geldstrafen, werden Verkäufer aus ihrer Arbeit verdrängt und die Märkte verlieren ihre Kundschaft. Diese Diplomarbeit erörtert Ursachen für diverse aktuelle Probleme sowie die dauerhaften Auswirkungen einer systematischen Vernachlässigung von Märkten und somit Ortsteilen von Zagreb. Sie bietet einen breiten Überblick über die vielfältigen Möglichkeiten der sozialen Disziplinen, die darauf gerichtet sind Daten zu sammeln und die räumlichen Bedürfnisse von Bürgern zu deuten, damit funktionale Städte mit gesunden Vierteln geschaffen werden. Die Wiederbelebung von bestehenden Märkten sowie ein Verständnis für die räumlichen Bedürfnisse der Bewohner werden in Form von zwei architektonischen Konzepten dargestellt.
description: The effect of markets on their surroundings represents not only their importance as an institution of social life and an urban place of gathering and coexistence, but also as a catalyst for positive development of urban morphology in content-poor quarters. Traditional markets are perceived as a part of Zagrebs cultural heritage and a symbol of an ongoing tradition, yet they deteriorate and lose their identity through poor and delayed reconstructions, relocations and a lack of infrastructure. Struck by discriminatory policies, unclear formal rules and high fines, the vendors are being put out of work and the markets lose their clientele. This thesis discusses causes of various current problems as well as permanent effects of systematic neglect of markets and thus places in Zagreb. It provides a broader perspective on a range of opportunities of social disciplines which aim to collect data and interpret the spatial needs of citizens in order to create functional cities with healthy quarters. Revitalizing existing markets as well as interpreting the spatial needs of the residents are presented in form of two architectural concepts.

description: In this study we compared the temporal and periodic variations of the Maximum CME Speed Index (MCMESI) and the number of different class (C, M, and X) solar X-Ray flares for the last two solar cycles (Cycle 23 and 24). To obtain the correlation between the MCMESI and solar flare numbers the cross correlation analysis was applied to monthly data sets. Also to investigate the periodic behavior of all data sets the Multi Taper Method (MTM) and the Morlet wavelet analysis method were performed with daily data from 2009 to 2018. To evaluate our wavelet analysis Cross Wavelet Transform (XWT) and Wavelet Transform Coherence (WTC) methods were performed. Causal relationships between datasets were further examined by Convergence Cross Mapping (CCM) method. In results of our analysis we found followings; 1) The C class X-Ray flare numbers increased about 16 % during the solar cycle 24 compared to cycle 23, while all other data sets decreased; the MCMESI decreased about 16 % and the number of M and X class flares decreased about 32 %. 2) All the X-Ray solar flare classes show remarkable positive correlation with the MCMESI. While the correlation between the MCMESI and C class flares comes from the general solar cycle trend, it mainly results from the fluctuations in the data in case of the X class flares. 3) In general, all class flare numbers and the MCMESI show similar periodic behavior. 4) The 546 days periodicity detected in the MCMESI may not be of solar origin or at least the solar flares are not the source of this periodicity. 5) C and M Class solar flares have a stronger causative effect on the MCMESI compared to X class solar flares. However the only bidirectional causal relationship is obtained between the MCMESI and C class flare numbers.

description: This deliverable “D2.1 – System scope” sets the pillars of AWARD project development, as the first deliverable of the “WP2 – Identification of end-users’ needs and requirements”. The task “T2.1 – Scope definition and refinement” lays out a solid ground for the project by reassessing and refining the overall scope of the targeted System of Systems, the selected overall use cases, ecosystem(s) of stakeholders and value chains, as well as innovation objectives.The content of the report focuses on the Use Cases (UC) description, users and stakeholders’ analysis of the 4 demonstrators, which will be used to develop and assess the AWARD Autonomous Driving System (ADS) innovative technology. A proper definition of the UC among the Consortium is key to set a common understanding of the UC needs and requirements that will be necessary as input to the subsequent project work packages.Then, the AWARD’s System of Systems (SoS) is introduced and detailed into its main components and subsystems interactions. The SoS definition will serve as an input for the subsequent WP2 tasks dedicated to the operational scenarios’ definition and to the functional requirements to be fulfilled by each subsystem described in this document. Then, the technical work packages will use the SoS breakdown and WP2 output analysis to achieve the safety studies based on SOTIF and ISO 26262, and the safety goals identified and classified according to the risk or hazard of ISO 26262.Finally, the AWARD value chains and the project innovative objectives are detailed, supporting the “T10.3 – Innovation management and impact monitoring” in the analysis of the scientific and technological achievements of the project.A Project Memorandum, synthesizing the outputs of the T2.1, is available in Annex 2 and will be visible on the project website.

description: We discuss the development, analysis, implementation, and numerical assessment of a spectral method for the numerical simulation of the three-dimensional Vlasov-Maxwell equations. The method is based on a spectral expansion of the velocity space with the asymmetrically weighted Hermite functions. The resulting system of time-dependent nonlinear equations is discretized by the discontinuous Galerkin (DG) method in space and by the method of lines for the time integration using explicit Runge-Kutta integrators. The resulting code, called Spectral Plasma Solver (SPS-DG), is successfully applied to standard plasma physics benchmarks to demonstrate its accuracy, robustness, and parallel scalability.

description: The triple alpha process plays an important role in the production of 12C in stars. Its rate is known with an accuracy of about 12%. We examine the corresponding uncertainties introduced in the description of pre-supernova stars, of nucleosynthesis in a core-collapse SN explosion, and of the production of 12C during the third dredge-up in asymptotic giant branch (AGB) stars. For the AGB case we consider also the effects of uncertainties in the 14N(p,gamma)15O rate. We conclude that the present accuracy of the triplr alpha rate is inadequate and describe new experiments that will lead to a more accurate value.

Purchasing power parity puzzle as a trade phenomenon
Creators: name: Berka, Martin
Publisher: name: University of British Columbia
Year: 2009

description: The purchasing power parity puzzle is among the central issues of international macroeconomics. In my thesis, I document and explain the persistence and volatility of its empirical counterpart - the real exchange rate - as a trade phenomenon arising from heterogeneous physical characteristics of products and geography. In the first chapter, a general equilibrium model with shipping costs that depend on physical characteristics of goods and distance leads to endogenous tradability of goods. Deviations of prices from parity are sustained as long as they do not exceed the heterogeneous trade frictions. The real exchange rate exhibits deviations whose persistence matches the data and, when quadratic adjustment costs in change of trade volume are added to the model, also the volatility of the real exchange rate deviations matches the data as well. The second chapter studies monthly deviations from the law of one price for a group of 63 goods and services in Canada and USA between 1970 and 2000 and relates them to a separate dataset of price-toweight and price-to-volume ratios. Threshold estimates are significantly negatively related to the estimates of the price-to-weight ratios and price-to-volume ratios, respectively. Physical characteristics of goods are important empirical determinants of heterogeneous non-linear behavior of deviations of their prices from parity. The third chapter studies the implications for monetary policy in a general equilibrium model where credit crunches occur due to shifts in the distribution of assets among heterogeneous households.

description: The atomic movement induced on melting has to overcome a viscous drag resistance. It is suggested that the latent heat of fusion supplies the required energy for this physical process. The viscosity model introduced here allows computation of the latent heat from viscosity, molar volume, melting temperature, and atomic mass and diameter. The correlation between these parameters and the latent heat of 14 elements with body and face centered cubic structures was exceptional, with the correlation coefficients of 0.97 and 0.95 respectively.

description: Diabetic retinopathy is the basic reason for visual deficiency. This paper introduces a programmed strategy to identify and dispense with the blood vessels. The location of the blood vessels is the fundamental stride in the discovery of diabetic retinopathy because the blood vessels are the typical elements of the retinal picture. The location of the blood vessels can help the ophthalmologists to recognize the sicknesses prior and quicker. The blood vessels recognized and wiped out by utilizing Gobar filter on two freely accessible retinal databases which are STARE and DRIVE. The exactness of segmentation calculation is assessed quantitatively by contrasting the physically sectioned pictures and the comparing yield pictures, the Gabor filter with Entropic threshold vessel pixel segmentation by Entropic thresholding is better vessels with less false positive portion rate.

description: We derive a microscopic equation of motion for the dynamical orientational correlators of molecular crystals. Our approach is based upon mode coupling theory. Compared to liquids we find four main differences: (i) the memory kernel contains Umklapp processes, (ii) besides the static two-molecule orientational correlators one also needs the static one-molecule orientational density as an input, where the latter is nontrivial, (iii) the static orientational current density correlator does contribute an anisotropic, inertia-independent part to the memory kernel, (iv) if the molecules are assumed to be fixed on a rigid lattice, the tensorial orientational correlators and the memory kernel have vanishing l,l'=0 components. The resulting mode coupling equations are solved for hard ellipsoids of revolution on a rigid sc-lattice. Using the static orientational correlators from Percus-Yevick theory we find an ideal glass transition generated due to precursors of orientational order which depend on X and p, the aspect ratio and packing fraction of the ellipsoids. The glass formation of oblate ellipsoids is enhanced compared to that for prolate ones. For oblate ellipsoids with X ~ 4, the critical diagonal nonergodicity parameters in reciprocal space exhibit more or less sharp maxima at the zone center with very small values elsewhere, while for prolate ellipsoids with 2

description: We develop the optimal trading strategy for a foreign exchange (FX) broker who must liquidate a large position in an illiquid currency pair. To maximize revenues, the broker considers trading in a currency triplet which consists of the illiquid pair and two other liquid currency pairs. The liquid pairs in the triplet are chosen so that one of the pairs is redundant. The broker is risk-neutral and accounts for model ambiguity in the FX rates to make her strategy robust to model misspecification. When the broker is ambiguity neutral (averse) the trading strategy in each pair is independent (dependent) of the inventory in the other two pairs in the triplet. We employ simulations to illustrate how the robust strategies perform. For a range of ambiguity aversion parameters, we find the mean Profit and Loss (P&L) of the strategy increases and the standard deviation of the P&L decreases as ambiguity aversion increases.

We show that the alleged arbitrariness of hyperreal fields can be avoided by working in the Kanovei-Shelah model or in saturated models. We argue that some of the objections to hyperreal probabilities arise from hidden biases that favor Archimedean models. We discuss the advantage of the hyperreals over transferless fields with infinitesimals. In the second part we will analyze two underdetermination theorems by Pruss and show that they hinge upon parasitic external hyperreal-valued measures, whereas internal hyperfinite measures are not underdetermined.

Interference between a large number of independent Bose-Einstein condensates

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We study theoretically the interference patterns produced by the overlap of an array of Bose-Einstein condensates that have no phase coherence among them. We show that density-density correlations at different quasimomenta, which play an important role in two-condensate interference, become negligible for large $N$, where $N$ is the number of overlapping condensates. In order to understand the physics of this phenomenon, it is sufficient to consider the periodicity of the lattice and the statistical probability distribution of a random-walk problem. The average visibility of such interference patterns decreases as $N^{-1/2}$ for large $N$.

description: In this paper we use density functional theory combined with dynamical mean-field theory (DFT+DMFT) to study interface effects between thin films of the correlated metal CaVO$_3$ and the two typical substrate materials SrTiO$_3$ and LaAlO$_3$. We find that the CaVO$_3$/SrTiO$_3$ interface has only a marginal influence on the CaVO$_3$ thin film, with the dominant effect being the (bulklike) epitaxial strain imposed by the large lattice mismatch, rendering the CaVO$_3$ film insulating due to the enhanced orbital polarization related to the strong level splitting between the t$_{\mathrm{2g}}$ orbitals. In contrast, at the polar CaVO$_3$/LaAlO$_3$ interface, the presence of the interface can have a huge effect on the thin film properties, depending both on the specific interface termination as well as the specific boundary conditions imposed by the multilayer geometry. We compare three different approaches to model the interface between the correlated metal CaVO$_3$ and the band insulator LaAlO$_3$, which all impose a different set of (electrostatic) boundary conditions on the electronic structure. The spectral properties obtained from our calculations reveal a strong influence of the supercell geometry, ranging from bulklike to highly doped and structurally distorted phases, indicating a potential tunability of the interfacial properties via multilayer engineering.

description: The interaction between free electrons and optical near fields is attracting increasing attention as a way to manipulate the electron wave function in space, time, and energy. Relying on currently attainable experimental capabilities, we design optical near-field plates to imprint a lateral phase on the electron wave function that can largely correct spherical aberration without the involvement of electric or magnetic lenses in the electron optics, and further generate on-demand lateral focal spot profiles. Our work introduces a disruptive and powerful approach toward aberration correction based on light-electron interactions that could lead to compact and versatile time-resolved free-electron microscopy and spectroscopy.

description: A serious adverse reaction of valproic acid (VPA), a widely used anti-epileptic, is a rare but potentially fatal hepatotoxicity affecting mostly children under 2 years of age with developmental delay and who are on VPA polytherapy. The mechanism of the hepatotoxicity remains unknown. This thesis describes in vivo and in vitro studies to examine the hypothesis that VPA increases oxidative stress in rats that in turn is associated with liver toxicity. 15-F[sub 2t]- Isoprostaglandin (15-F[sub 2t]-lsoP), a free-radical catalyzed, lipid peroxidation breakdown product of arachidonic acid, was measured as an indicator of oxidative stress. Our findings showed a dose-dependent elevation in plasma and liver 15- F[sub 2t]-lsoP with plasma concentration-time profiles similar to that of the drug in rats given a single high dose of VPA. This increase in 15-F[sub 2t]-lsoP did not involve cytochrome P450-mediated biotransformation even though rats treated with both phenobarbital (PB) and VPA resulted in greater levels of 15-F[sub 2t]-lsoP compared to rats treated with only VPA. These results prompted further mechanistic studies in rats to establish an association between VPA glucuronidation and 15-F[sub 2t]-lsoP levels. VPA glucuronidation, the major VPA biotransformation pathway, correlated with 15-F[sub 2t]-lsoP formation. Levels of both 15-F[sub 2t]-lsoP and VPA-1-O-acyl glucuronide (VPA-G) were elevated by PB and reduced by inhibitors of VPA-glucuronidation in rats after a single dose of VPA. The fluorinated analogue of VPA (afluoro- VPA), which was a poor substrate for glucuronidation, did not elevate 15-F[sub 2t]-lsoP levels. To determine whether there was a temporal relationship between VPA-associated oxidative stress and hepatotoxicity, rats were given high daily doses of VPA for 14 days. VPA elevated levels of 15-F[sub 2t]-lsoP prior to the onset of hepatic necrosis and steatosis. An in vitro model using primary cultured rat hepatocytes also demonstrated that VPA induces oxidative stress as measured by elevated levels of 15-F[sub 2t]-lsoP and 2',7'-dichlorofluorescein (DCF). In hepatocytes with reduced levels of glutathione, these oxidative stress biomarkers were further elevated, and were accompanied by mitochondrial dysfunction and hepatocyte toxicity. The work presented is significant in that it supports the hypothesis that VPA-associated oxidative stress occurs prior to hepatotoxicity and the link of acyl glucuronidation of VPA to the production of reactive oxygen species is unique.

description: The open-source PyNX toolkit [Favre-Nicolin et al (2011) arXiv:1010.2641, Mandula et al (2016)] has been extended to provide tools for coherent X-ray imaging data analysis and simulation. All calculations can be executed on graphical processing units (GPU) to achieve high performance computing speeds. This can be used for Coherent Diffraction Imaging (CDI), Ptychography and wavefront propagation, in the far or near field regime. Moreover, all imaging operations (propagation, projections, algorithm cycles..) can be used in Python as simple mathematical operators, an approach which can be used to easily combine basic algorithms in a tailored chain. Calculations can also be distributed to multiple GPUs, e.g. for large Ptychography datasets. Command-line scripts are also available for on-line CDI and Ptychography analysis, either from raw beamline datasets or using the Coherent X-ray Imaging data format [Maia (2012)].

description: This paper describes how to specify, estimate, and test multiple-equation, fixed-effect, panel-data equations in Stata. By specifying the system of equations as seemingly unrelated regressions, Stata panel-data procedures worked seamlessly for estimation and testing of individual variable coefficients, but additional routines using test were needed for testing of individual equations and differences between equations.

Smart helical structures inspired by the pellicle of euglenids

description: This paper deals with a concept for a reconfigurable structure bio-inspired by the cell wall architecture of euglenids, a family of unicellular protists, and based on the relative sliding of adjacent strips. Uniform sliding turns a cylinder resulting from the assembly of straight and parallel strips into a cylinder of smaller height and larger radius, in which the strips are deformed into a family of parallel helices. We examine the mechanics of this cylindrical assembly, in which the interlocking strips are allowed to slide freely at their junctions, and compute the external forces (axial force and axial torque at the two ends, or pressure on the lateral surface) necessary to drive and control the shape changes of the composite structure. Despite the simplicity of the structure, we find a remarkably complex mechanical behaviour that can be tuned by the spontaneous curvature or twist of the strips.

description: Neutrinos with energy greater than GeV are copiously produced in the p(A,p) interactions occurring in several astrophysical sites such as (i) the earth atmosphere, (ii) our galactic plane as well as in (iii) the galaxy clusters. A comparison of the tau and mu neutrino flux in the presence of neutrino oscillations from these three representative astrophysical sites is presented. It is pointed out that the non-atmospheric tau neutrino flux starts dominating over the downward going atmospheric tau neutrino flux for neutrino energy E as low as 10 GeV. This energy value is much lower than the energy value, E \geq 5\times 10^4 GeV, estimated for the dominance of the non-atmospheric mu neutrino flux, in the presence of neutrino oscillations. Future prospects for possible observations of non-atmospheric tau neutrino flux are briefly mentioned.

description: It is not only conceivable but likely that the spectrum of physics beyond the Standard Model (SM) is non-degenerate. The lightest non-SM particle may reside close enough to the electroweak scale that it can be kinematically probed at high-energy experiments and on account of this, it must be included as an infrared (IR) degree of freedom (DOF) along with the SM ones. The rest of the non-SM particles are heavy enough to be directly experimentally inaccessible and can be integrated out. Now, to capture the effects of the complete theory, one must take into account the higher dimensional operators constituted of the SM DOFs and the minimal extension. This construction, BSMEFT, is in the same spirit as SMEFT but now with extra IR DOFs. Constructing a BSMEFT is in general the first step after establishing experimental evidence for a new particle. We have investigated three different scenarios where the SM is extended by additional (i) uncolored, (ii) colored particles, and (iii) abelian gauge symmetries. For each such scenario, we have included the most-anticipated and phenomenologically motivated models to demonstrate the concept of BSMEFT. In this paper, we have provided the full EFT Lagrangian for each such model up to mass dimension 6. We have also identified the $CP$, baryon ($B$), and lepton ($L$) number violating effective operators.

description: Citing data and software is a means to give scholarly credit and to facilitate access to research objects. Citation principles encourage authors to provide full descriptions of objects, with stable links, in their papers. As Jupyter notebooks aggregate data, software, and other objects, they may facilitate or hinder citation, credit, and access to data and software. We report on a study of references to Jupyter notebooks in astronomy over a 5-year period (2014-2018). References increased rapidly, but fewer than half of the references led to Jupyter notebooks that could be located and opened. Jupyter notebooks appear better suited to supporting the research process than to providing access to research objects. We recommend that authors cite individual data and software objects, and that they stabilize any notebooks cited in publications. Publishers should increase the number of citations allowed in papers and employ descriptive metadata-rich citation styles that facilitate credit and discovery.
