description: The VSOP mission is a Japanese-led project to study radio sources with sub-milliarcsec resolution using an orbiting 8 m telescope, HALCA, along with global arrays of Earth-based telescopes. Approximately 25% of the observing time is devoted to a survey of compact AGN which are stronger than 1 Jy at 5 GHz-the VSOP AGN Survey. This paper, the third in the series, presents the results from the analysis of the first 102 Survey sources. We present high resolution images and plots of visibility amplitude versus projected baseline length. In addition, model-fit parameters to the primary radio components are listed, and from these the angular size and brightness temperature for the radio cores are calculated. For those sources for which we were able to determine the source frame core brightness temperature, a significant fraction (53 out of 98) have a source frame core brightness temperature in excess of 10^12 K. The maximum source frame core brightness temperature we observed was 1.2 X 10^13 K. Explaining a brightness temperature this high requires an extreme amount of relativistic Doppler beaming. Since the maximum brightness temperature one is able to determine using only ground-based arrays is of the order of 10^12 K, our results confirm the necessity of using space VLBI to explore the extremely high brightness temperature regime.

Urbanotopia and the frontier : reaching heights before the crash in Moscow and New York at the end of the 1920s
Creators: name: Idzior, Aleksandra
Publisher: name: University of British Columbia

description: My dissertation investigates, at its broadest level, the visualization of the future city in Moscow and New York at the end of the 1920s. In particular I examine two imaginative designs executed in the form of "paper architecture." One proposition was delivered by Georgii Tikhonovich Krutikov, a Soviet student of architecture, who in 1928 presented a diploma project called "Gorod budushchego" (City of the Future), and the other model was suggested by Hugh Ferriss, an architectural Tenderer, in his book entitled "The Metropolis of Tomorrow", published in 1929.1 want to discover the circumstances that prompted these two architects to suggest intriguing concepts of the ideal city, in which both authors employed similar metaphors, associated with height and a skyward trend applied to urban space. Evidently their projects announced novel ways to rethink the form of a modern city, but why is the improbable concept of " flying" such an important part of Krutikov's gorod, and why does Ferriss's metropolis evoke mountainous formations? What were the conditions at play at the end of the 1920s that prompted both architects to propose such eccentric visions? Since Krutikov's professional debut coincided with the Communist Party's adoption of Stalin's First Five-Year-Plan (October 1928 - December 1932), and Ferriss's publication concurred with the Wall Street Crash inl929, my interest leads me to reevaluate these two projects according to issues and ideas residing outside of aesthetics and to disclose the politics of representation involved in their production. Hence, my work considers how artistic practice is interconnected with socio-political issues in albeit politically and culturally distinguishable centres. As this thesis demonstrates, Krutikov and Ferriss responded to these growing tensions by imbuing their Utopian urban spaces with concepts related to boundaries and limits, and by applying rhetoric and visual vocabulary that resound with issues occupying the Soviet and American "frontier" paradigm, respectively. However, as this study concludes, while appreciating Krutikov's and Ferriss's great imagination and the dilemmas each of them faced, we should recognize the vicissitudes of their concepts, and how the following events, especially of the 1930s, revealed that Utopian thinking is vulnerable, or perhaps induced to become a dystopian reality.
Ultrafast photoluminescence in metals: Theory and its application to silver

description: We study the transient photoluminescence (PL) of photoexcited metals by solving the Boltzmann equation considering the effects of electron-electron (e-e) and electron-phonon (e-ph) collisions, where the e-ph coupling function is calculated from first-principles in order to account for the energy transfer rate between electrons and phonons accurately. We apply the present scheme to the transient PL of silver and demonstrate that the agreement between the theory and experiment is good, where the effect of nonequilibrium electron distribution is significant to fit the experimental data. The effects of the nanoscale roughness at metal surfaces and the e-e umklapp scattering on ultrafast electron dynamics are also discussed.

description: A 2D quantum ballistic transport model based on the non-equilibrium Green's function formalism has been used to theoretically investigate the effects induced by an oxide crenel in a very short (7 nm) thin-film metal-oxide-semiconductor-field-effect-transistor. Our investigation shows that a well adjusted crenel permits an improvement of on-off current ratio Ion/Ioff of about 244% with no detrimental change in the drive current Ion. This remarkable result is explained by a nontrivial influence of crenel on conduction band-structure in thin-film. Therefore a well optimized crenel seems to be a good solution to have a much better control of short channel effects in transistor where the transport has a strong quantum behavior.

description: Single crystals of Mg1-xAlxB2 have been grown at a pressure of 30 kbar using the cubic anvil technique. Precipitation free crystals with x < 0.1 were obtained as a result of optimization of already developed MgB2 crystal growth procedure. Systematic decrease of the c-axis lattice constant with increasing Al content, when the a-axis lattice constant is practically unchanged, was observed. Variation of the critical temperature on Al content in Mg1-xAlxB2 crystals was found to be slightly different than that one observed for polycrystalline samples since, even a very small substitution of 1-2% of Al leads to the decrease of Tc by about 2-3 K. X-ray and high resolution transmission electron microscopy investigations indicate on the appearance of second precipitation phase in the crystals with x > 0.1. This is in a form of non-superconducting MgAlB4 domains in the structure of superconducting Mg1-xAlxB2 matrix. Resistivity and magnetic investigations show the slight increase of the upper critical field, Hc2, for H//c for the samples with small x, significant reduction of the Hc2 anisotropy at lower temperatures, and decrease of the residual resistance ratio value for Al substituted samples as compared to those of unsubstituted crystals. Superconducting gaps variation as a function of Al content, investigated with point contact spectroscopy for the series of the crystals with Tc in the range from 20 to 37 K, does not indicate on the merging of the gaps with decreasing Tc down to 20 K. It may be related to an appearance of the precipitation phase in the Mg1-xAlxB2 structure.

description: An enzymatic approach for the synthesis of intermediate alcohol of the drug tegoprazan in 99% ee at 20 °C in hexane has been developed utilizing commercially available immobilized Thermomyces lanuginosus lipase (TL lipase) as a biocatalyst and vinyl acetate as a acyl donor. This method involves the enantioselective esterification of (RS)-5,7-difluorochroman-4-ol with vinyl acetate using TL Lipase. This enzymatic approach provides the (S)-chiral alcohol in 44% yield with 99% enantiomeric excess (ee) and the (R)-acetate in 43% yield and >99% ee. It is a sustainable approach for the synthesis of enantiopure tegoprazan intermediate, contributing to the advancement of green chemistry. The recovered TL lipase was reused in 13 subsequent runs without loss of activity.

description: In this paper we analyze the asymptotic behavior of Cardassian cosmological models filled with a perfect fluid and a scalar field with an exponential potential. Cardassian cosmologies arise from modifications of the Friedmann equation, and among the different proposals within that framework we will choose those of the form $3H^2-ρ\propto ρ^n$ with $n<1$. We construct two three dimensional dynamical systems arising from the evolution equations, respectively adapted for studying the high and low energy limits. Using standard dynamical systems techniques we find the fixed points and characterize the solutions they represent. We pay especial attention to the properties inherent to the modifications and compare with the (standard) unmodified scenario. Among other interesting results, we find there are no late-time tracking attractors.

description: Quantum tunneling dominates the low temperature magnetization dynamics in molecular magnets and presents features that are strongly system dependent. The current discussion is focused on the terbium(III) bis(phtalocyanine) ([TbPc$_2$]$^{-1}$) complex, that should serve as a prototypical case for lanthanide molecular magnets. We analyze numerically the effect of non-axial interactions on the magnitude of the intrinsic tunnel splitting and show that usual suspects like the transverse ligand field and Zeeman interaction fail to explain the experimentally observed dynamics. We then propose through the nuclear quadrupolar interaction a viable mechanism that mixes, otherwise \textit{almost} degenerate hyperfine states.

description: This work presents for the first time a flexible over-moded resonator (OMR) based on P(VDF-TrFE) thin films. The devices were manufactured on commercially available elastic substrate with inkjet-printed electrodes. The sensing copolymer films used in the devices were polarized by the corona method after electrode deposition. The main performance parameters of the component were then determined. The manufactured OMRs on P(VDF-TrFE) exhibited a linear variation of frequency versus temperature and a very large value of temperature coefficient of frequency (TCF > 1600 ppm/degrees C). These properties suggest a great potential for using such components as low-cost and high-precision temperature sensors. The electromechanical coupling coefficient and the quality factor of the resonator were also characterized versus temperature.

description: This paper investigates comparative trade advantages in agro-food trade. We analyze comparative advantages of Hungarian, Croatian and Slovenian agro-food trade in the European Union (EU) markets. Both the levels and pattern of the revealed comparative advantage measure are investigated. The empirical research seeks to explain how revealed comparative advantages have developed across countries, main product groups and over time and what are likely their implications for multifunctional rural development in the enlarged EU. We employ a disaggregated trade dataset to identify the revealed comparative advantages to provide broader policy implications. The empirical results confirmed bulk of agro-food and forestry products with revealed comparative advantages in the EU markets for Hungary and to a lesser extent for Croatia, but have not identified any such aggregated agro-food product group for Slovenia. Yet, also Hungary and Croatia have faced difficulties in comparative trade advantages in consumer-ready foods and processed intermediaries. Agro-food sectors in Hungary are likely to continue to have a significant role in the Hungarian and to a lesser extent in Croatian rural areas, but employment and income activities are more likely to be combined with other more rapidly growing service activities. In Slovenia, traditional agro-food activities under increasing competitive pressures are more likely to shrink.

description: The paper investigates spatial changes in cultivation and land use of wheat, maize and oilseed in Hungarian agriculture using different methods to measure these changes. The results suggest that spatial structure of crop productions has remained fairly stable during analysed period. The spatial concentration increased significantly for wheat and maize production and maize land use, whilst the changes were not significant for other cases. Estimates confirm the presence of spatial autocorrelation for all cases. The degree of spatial autocorrelation has no unambiguous pattern over time, except for maize production. Finally, we have not found significant relationship measured by PSE index between agricultural support and spatial concentration, but estimates show positive and significant effects of the share of private farms in the production of certain crops on spatial concentration.

description: The main goal of this paper is to establish the nonlocal-to-local convergence of strong solutions to a Navier–Stokes–Cahn–Hilliard model with singular potential describing immiscible, viscous two-phase flows with matched densities, which is referred to as the Model H. This means that we show that the strong solutions to the nonlocal Model H converge to the strong solution to the local Model H as the weight function in the nonlocal interaction kernel approaches the delta distribution. Compared to previous results in the literature, our main novelty is to further establish corresponding convergence rates. Before investigating the nonlocal-to-local convergence, we first need to ensure the strong well-posedness of the nonlocal Model H. In two dimensions, this result can already be found in the literature, whereas in three dimensions, it will be shown in the present paper. Moreover, in both two and three dimensions, we establish suitable uniform bounds on the strong solutions of the nonlocal Model H, which are essential to prove the nonlocal-to-local convergence results.

description: An die russische Agrarreform der 1990er Jahre knüpfte sich die Erwartung, dass entsprechend der Erfahrung in westlichen Staaten landwirtschaftliche Familienbetriebe (Fermer-Betriebe) an die Stelle der staatlichen Großbetriebe treten und einen Aufschwung in der russischen Landwirtschaft auslösen würden. Entgegen dieser Erwartungen ist der russische Fermer-Sektor bis heute verhältnismäßig schwach entwickelt, während die Landwirtschaft als eines der wichtigsten Problemfelder der russischen Innenpolitik gilt. Im vorliegenden Discussion Paper werden die für die Entstehung des Fermer-Sektors relevanten Aspekte der russischen Agrarreform nachvollzogen sowie auf der Grundlage russischer Statistiken die gegenwärtige Lage der russischen Landwirtschaft analysiert. Im Discussion Paper werden weiterhin die in der russischen Debatte angeführten Argumente für die Überlegenheit von Fermer-Betrieben und verschiedene Erklärungsansätze für die eher unbedeutende Rolle des russischen Fermer-Sektors vorgestellt.

description: The role of repulsive interactions in statistical systems of Bose particles is investigated. Three different phenomenological frameworks are considered: a mean field model, an excluded volume model, and a model with a medium dependent effective mass. All three models are tuned to yield similar equations of state, with only minor deviations from the ideal Bose gas at small chemical potentials. Our analysis indicates, however, that these models lead to qualitatively different results for the Bose-Einstein condensation phenomenon. We discuss the different aspects of this phenomenon, namely, an onset of the Bose-Einstein condensation, particle number fluctuations, and a behavior of the Bose condensate. The obtained results can be helpful for interpreting the lattice QCD data at small temperature and large isospin chemical potential and the data on multiple pion production in high energy nuclear collisions.

description: Microquasars are potential candidates to produce a non-negligible fraction of the observed galactic cosmic rays. The protons accelerated at the jet termination shock interact with the interstellar medium and may produce detectable fluxes of extended emission at different energy bands: high-energy and very high-energy gamma-rays produced by neutral pion-decay, synchrotron and bremsstrahlung emission in a wide energy range generated by the secondary electrons produced by charged pion-decay. We discuss the association between this scenario and some of the unidentified EGRET sources in the galactic plane.

description: Quantum transport properties of electron systems driven by strong electric fields are studied by mapping the Landau-Zener transition dynamics to a quantum walk on a semi-infinite one-dimensional lattice with a reflecting boundary, where the sites correspond to energy levels and the boundary the ground state. Quantum interference induces a distribution localized around the ground state, and when the electric field is strengthened, a delocalization transition occurs describing breakdown of the original electron system.

description: Monitoring location updates from mobile users has important applications in many areas, ranging from public safety and national security to social networks and advertising. However, sensitive information can be derived from movement patterns, thus protecting the privacy of mobile users is a major concern. Users may only be willing to disclose their locations when some condition is met, for instance in proximity of a disaster area or an event of interest. Currently, such functionality can be achieved using searchable encryption. Such cryptographic primitives provide provable guarantees for privacy, and allow decryption only when the location satisfies some predicate. Nevertheless, they rely on expensive pairing-based cryptography (PBC), of which direct application to the domain of location updates leads to impractical solutions. We propose secure and efficient techniques for private processing of location updates that complement the use of PBC and lead to significant gains in performance by reducing the amount of required pairing operations. We implement two optimizations that further improve performance: materialization of results to expensive mathematical operations, and parallelization. We also propose an heuristic that brings down the computational overhead through enlarging an alert zone by a small factor (given as system parameter), therefore trading off a small and controlled amount of privacy for significant performance gains. Extensive experimental results show that the proposed techniques significantly improve performance compared to the baseline, and reduce the searchable encryption overhead to a level that is practical in a computing environment with reasonable resources, such as the cloud.

Gene polymorphisms in renal transplantation

description: Despite optimal HLA matching and advances in immunosuppressive therapy, acute rejection remains a leading cause of transplant failure. Increasing evidence suggests that T-cell activation and response to immunosuppression vary widely between individuals, and that these functional differences may be related at least in part to polymorphisms within critical immune response genes. Testing for these polymorphisms may therefore provide a simple and clinically important method for predicting rejection risk and guiding therapy in renal transplantation. Genetic polymorphisms of two groups of genes (T-cell signaling molecules and cytokine genes) were studied in renal transplant patients who did (AR group) or did not (NR group) experience acute rejection episodes during the first year after transplant. CTLA-4, CD45, and CD40L signaling molecules and TGF-β1, IL-10, TNF-α, and IFN-γ cytokine gene polymorphisms were examined. PCR-RFLP, SNP, and fragment length analysis of dinucleotide repeats were used to study the relationship between genetic polymorphisms and the frequency of acute rejection. The allele frequencies at each gene locus were determined for the study groups and compared to the control population by Fisher's exact test. Multiple logistic regression analysis was performed using statistical language R, version 1.8.0 (2004), software. There was no significant difference in the frequency of the CTLA-4 (-318 C/T and +49 A/G), and TGF-pi (+600 T/C and +650 G/C) genes RFLP in patients with acute renal transplant rejection in a comparison with patients with no rejection. The variant (G⁺⁷⁷) allele of the CD45 gene was not detected in the study population. Univariate analysis of SNP polymorphisms at the IL-10 (-1082 A/G) and TNF-a (-308 A/G) genes, and LFN-γ and CD40L dinucleotide repeat polymorphisms did not reach a level of statistical significance. However, multiple logistic regression analysis which incorporated demographic and clinical data, demonstrated a significant difference for the CD40L 157 1* and 2* alleles between the AR and NR groups (OR=0.58 and OR=0, respectively; p value=0.005), with the proportion of patients carrying the CD40L 157 allele being higher in the NR than in the AR group. This finding suggests that the CD40L 157 allele may have a protective effect in renal transplantation and requires further investigation.

Marked influence of the nature of chemical bond on CP-violating signature in molecular ions $\mathrm{HBr}^{+}$ and $\mathrm{HI}^{+}$

description: Heavy polar molecules offer a great sensitivity to the electron Electric Dipole Moment(EDM). To guide emerging searches for EDMs with molecular ions, we estimate the EDM-induced energy corrections for hydrogen halide ions $\mathrm{HBr}^{+}$ and $\mathrm{HI}^{+}$ in their respective ground $X ^2Π_{3/2}$ states. We find that the energy corrections due to EDM for the two ions differ by an unexpectedly large factor of fifteen. We demonstrate that a major part of this enhancement is due to a dissimilarity in the nature of the chemical bond for the two ions: the bond that is nearly of ionic character in $\mathrm{HBr}^{+}$ exhibits predominantly covalent nature in $\mathrm{HI}^{+}$. We conclude that because of this enhancement the HI$^+$ ion may be a potentially competitive candidate for the EDM search.

description: Land is a natural resource that is valued for many reasons. Farmers utilize land to earn their livelihood and as a store of wealth for future retirement. Potential rural residents have increasingly sought open space for a home site and pursuit of a lifestyle. Developers seek financial opportunities to invest in and develop it for non-farm uses. Recreational needs such as hunting are often met through use of land. For some, land is viewed as an investment and a hedge against inflation. This myriad of demands for land combined with its fixed supply continually alters its market price, which is a monetary measure of its perceived value.

description: Spectral slopes in optical transmission spectra of exoplanetary atmospheres encapsulate information on the properties of exotic clouds. The slope is usually attributed to the Rayleigh scattering caused by tiny aerosol particles, whereas recent retrieval studies have suggested that the slopes are often steeper than the canonical Rayleigh slopes. Here, we propose that photochemical haze formed in vigorously mixing atmospheres can explain such super-Rayleigh slopes. We first analytically show that the spectral slope can be steepened by the vertical opacity gradient in which atmospheric opacity increases with altitude. Using a microphysical model, we demonstrate that such opacity gradient can be naturally generated by photochemical haze, especially when the eddy mixing is substantially efficient. The transmission spectra of hazy atmospheres can be demarcated into four typical regimes in terms of the haze mass flux and eddy diffusion coefficient. We find that the transmission spectrum can have the spectral slope 2--4 times steeper than the Rayleigh slope if the eddy diffusion coefficient is sufficiently high and the haze mass flux falls into a moderate value. Based on the eddy diffusion coefficient suggested by a recent study of atmospheric circulations, we suggest that photochemical haze preferentially generates super-Rayleigh slopes at planets with equilibrium temperature of 1000--1500 K, which might be consistent with results of recent retrieval studies. Our results would help to interpret the observations of spectral slopes from the perspective of haze formation.

description: Our previous ``exotic'' particle, together with the more recent anomalous anyon model (which has arbitrary gyromagnetic factor $g$) are reviewed. The non-relativistic limit of the anyon generalizes the exotic particle which has $g=0$ to any $g$.When put into planar electric and magnetic fields, the Hall effect becomes mandatory for all $g\neq2$, when the field takes some critical value.

description: This paper reports on and interprets the results of a survey of visitors to the Jourama Falls Section of the Paluma Range National Park located in Northern Queensland. It reports, amongst other things, on how much knowledge visitors to the site had about it before their visit, the procedures they adopted in deciding to visit it and how generally they go about deciding to visit tourist sites when on holidays. The results are consistent with those predicted by theories of bounded rationality and behavioural economics. Information is also provided on the value visitors placed on attractions at the Jourama Falls sites, their attitudes to the private supply of tourist/visitor services and facilities in national parks, the importance of wildlife as an attraction to visitors at this site and their knowledge of it. In addition, the attitudes of visitors to facilities, camping procedures, environmental issues and activities at this site are assessed as well as the acceptability to respondents of an entrance fee. A halo, proximity or local existence effect was observed in relation to wildlife present at Jourama Falls but not visible.

description: We present a comprehensive full-sky 3-dimensional analysis of the weak-lensing fields and their corresponding power spectra. Using the formalism of spin-weight spherical harmonics and spherical Bessel functions, we relate the two-point statistics of the harmonic expansion coefficients of the weak lensing shear and convergence to the power spectrum of the matter density perturbations, and derive small-angle limits. Such a study is relevant in view of the next generation of large-scale weak lensing surveys which will provide distance information about the sources through photometric redshifts. This opens up the possibility of accurate cosmological parameter estimation via weak lensing, with an emphasis on the equation of state of dark energy.
