description: This paper presents a procedure used to estimate the recreational use value of “Tablas de Daimiel” National Park by applying the Contingent Valuation Method (CVM) with single dichotomous choice, using the truncated mean as welfare measure. This valuation is based on 433 interviews of visitors made during the spring and summer 1996. The sample allocation among the bids offered in the surveys is based on the Duffield and Patterson’s method which allows to get the minimal variance of the truncated mean estimator. The recreational values of the Park are not significantly different for the two periods in which the surveys have been carried out. Finally, the tests to study the “interviewers effect” and to analyse the relations between the willingness to pay (WTP) and various interviewees’ features don’t invalidate the procedure adopted to determine the recreational use value of this National Park.

description: The first-order reversal curve (FORC) method is applied to the two-dimensional kinetic Ising model. For the system size and magnetic field chosen, the system reverses by the homogeneous nucleation and growth of many droplets. This makes the dynamics of reversal nearly deterministic, in contrast to the strongly disordered systems previously studied by the FORC method. Consequently, the FORC diagrams appear different from those obtained in previous studies. The Kolmogorov-Johnson-Mehl-Avrami (KJMA) theory of phase transformation by nucleation and growth is applied to the system. Reasonable agreement with the Monte Carlo simulations is found, and the FORC method suggests how the KJMA theory could be extended.

description: This thesis aims to analyze the feasibility of entering the Russian food market for a small Austrian automation company, particularly in the light of the recent economic crisis and import substitution campaign. To this end, the company's profile and product portfolio have been studied and a preferable mode of entry selected. Apart from that, Russia's business environment has been assessed with a particular focus on the meat, bakery and confectionery industries. Finally, a theoretical framework for an internationalization strategy has been developed and specific recommendations with regard to the implementation of this strategy have been provided. The study has been carried out based on the information obtained from a large body of theoretical and empirical literature. Additionally, a series of semi-structured expert interviews have been conducted and an online survey created to gain an insight into the specific challenges associated with doing business in Russia. This study can be of particular value to small companies that are interested in exploring the Russian market, especially in the food industry.
Priced out : a profile of tenant households and their capacity to enter homeownership in metropolitan Canada
Creators: name: Mendez-Gonzalez, Juan-Pablo
Publisher: name: University of British Columbia
Year: 2010

description: A booming housing market in the early years of the twenty-first century has favoured hundreds of thousands of home-owning households in metropolitan Canada, doing much in the process to jumpstart an unwinding economy. But rapidly rising house prices have also revived the twin spectres of declining affordability and a widening economic gap between tenants and homeowners. Given the serious long-term negative consequences of tenure-driven polarisation, it becomes increasingly necessary to extend current research beyond its prevailing emphasis on the risk of downward housing mobility, and engage in complementary analyses of the ability of households to achieve an upward transition of tenure. My thesis therefore examines the financial capacity of tenant households to enter homeownership in Montreal, Toronto and Vancouver (MTV), exploring how various socio-demographic characteristics affect their likelihood to qualify for a mortgage on a moderate or average priced dwelling. My reference point in time is 2001, a year marked by a Census of Population, a bottoming out of real house prices, falling interest rates, and the first stirrings of a housing boom that took off in full stride the following year. Through a descriptive statistical analysis of 2001 Census data, I draw a profile of the more than one million tenant households which the market had already priced out of homeownership in MTV prior to the price explosion of 2002. Geography and economic class seemed to be more important determinants of homeownership accessibility than other household characteristics, but certain demographic subgroups were nonetheless found to exhibit polarising tendencies along the tenure line, especially in Vancouver, the most expensive housing market. Moreover, cohort effects related to age, economic cycles, and immigrants’ time of arrival appeared to interact in defining ways with other variables, particularly those related with the life-cycle model and with immigrant status. Finally, my findings suggest that post-facto analyses of homeownership attainment, when conducted on their own, cannot be relied upon for the purposes of studying the financial accessibility of owner occupancy. Market factors relative to tenants ’ incomes (such as current mortgage rates, borrowing conditions, and local dwelling prices) need to be incorporated as well.

description: Gravitational waves from the merger of two neutron stars cannot be easily distinguished from those produced by a comparable-mass mixed binary in which one of the companions is a black hole. Low-mass black holes are interesting because they could form in the aftermath of the coalescence of two neutron stars, from the collapse of massive stars, from matter overdensities in the primordial Universe, or as the outcome of the interaction between neutron stars and dark matter. Gravitational waves carry the imprint of the internal composition of neutron stars via the so-called tidal deformability parameter, which depends on the stellar equation of state and is equal to zero for black holes. We present a new data analysis strategy powered by Bayesian inference and machine learning to identify mixed binaries, hence low-mass black holes, using the distribution of the tidal deformability parameter inferred from gravitational-wave observations.

description: Recent demonstrations of superconducting quantum computers by Google and IBM and trapped-ion computers from IonQ fueled new research in quantum algorithms, compilation into quantum circuits, and empirical algorithmics. While online access to quantum hardware remains too limited to meet the demand, simulating quantum circuits on conventional computers satisfies many needs. We advance Schrödinger-style simulation of quantum circuits that is useful standalone and as a building block in layered simulation algorithms, both cases are illustrated in our results. Our algorithmic contributions show how to simulate multiple quantum gates at once, how to avoid floating-point multiplies, how to best use instruction-level and thread-level parallelism as well as CPU cache, and how to leverage these optimizations by reordering circuit gates. While not described previously, these techniques implemented by us supported published high-performance distributed simulations up to 64 qubits. To show additional impact, we benchmark our simulator against Microsoft, IBM and Google simulators on hard circuits from Google.

title: Public participation in the Water Framework Directive : a comparative review: Austria and France

Subjects: subject: Water Framework Directive
subject: Public Participation

description: Over the past decades, general environmental consciousness has increased and triggered a tremendous movement, which finally led to the adoption of public participation provisions in international conventions and ultimately in legally binding Directives in the European Union. The Water Framework Directive and the Aarhus Convention represent two of them. A review of the public participation processes in Austria and France is assessed in this Thesis by using a case study approach. It investigates differences and commonalities and builds on state of the art research, which suggests that there is still a long way to go, until a successful implementation of public participation processes can be established. Even though the main findings support this conclusion, this research has shown, that a certain extent of accountability and transparency has been reached through the newly embedded public participation provisions. The public, as well as the Institutions of the European Union can monitor and evaluate the developments of the Member States and hold them to account. While France has a long tradition in public participation, Austria has only started public participation with the advent of the WFD. Naturally, this aspect influences the outcome of this research. Nevertheless, in the final analysis, it can be said that for the most part the WFD has been successful in regards to its public participation provisions. The public, as well as the Institutions of the European Union can monitor and evaluate the developments of the Member States.

description: We report a novel atom extraction mechanism from the native substrate by means of a scanning tunneling microscope tip-crash on a Ag(111) surface at 5 K. Individual atoms are scattered on the surface when a silver coated tip is dipped into the substrate at low tunneling biases. Quantitative analyses reveal that the mechanical energy supplied by the tip-crash dominates the atom extraction process. Application of this procedure is demonstrated by constructing quantum structures using the extracted atoms on an atom-by-atom basis.

description: We consider the ground state of the XY model on an infinite chain at zero temperature. Following Bennett, Bernstein, Popescu, and Schumacher we use entropy of a sub-system as a measure of entanglement. Vidal, Latorre, Rico and Kitaev conjectured that von Neumann entropy of a large block of neighboring spins approaches a constant as the size of the block increases. We evaluated this limiting entropy as a function of anisotropy and transverse magnetic field. We used the methods based on integrable Fredholm operators and Riemann-Hilbert problem. The entropy is singular at phase transitions.

description: Accurate information on HIV transmission risk is required to construct evidence-based risk reduction practices for individuals and to direct the provision of prevention strategies at the population level. HIV transmission risk assessment will help in identifying individuals at high risk of HIV infection and directing the provision of post exposure prophylaxis (PEP). To identify the common risk factors for HIV transmission in the Egyptian community in order to construct a web-based HIV risk assessment tool. Following a systematic review and meta-analysis of published literature on HIV transmission and risk factors, we retrieved the key determinants of HIV exposure risk. In parallel, we conducted a case control study to identify the common risk factors for HIV transmission in the Egyptian community. The identified risk factors were incorporated in weighted risk scoring models to allow the quantification of the risk of HIV acquisition. There were 38 determinants associated with HIV seropositivity [people living with HIV (PLWH)] among Egyptians compared to 34 risk factors identified in our meta-analysis. All the derived scores showed high accuracy for predicting HIV infection status [sensitivity, specificity, PPV and NPV of greater than 90.0%, (AUC = 0.998–1.000; p Key drivers of HIV transmissions can be incorporated into a risk scoring model in order to quantify the risks of HIV acquisition. Such tools can facilitate the screening of PLWH and at-risk-individuals and direct interventions to halt HIV transmission.
New directions in microwave spectroscopy of high temperature superconductors
Creators: name: Musselman, Kevin Philip Duncan
Publisher: name: University of British Columbia
Year: 2010

description: Two new variations on traditional microwave resonant cavity surface resistance measurements of high temperature superconductors are presented. A new cavity perturbation technique is developed for the measurement of T1₂Ba₂CuO₆±[delta] (Tl-2201) single crystals, and preliminary measurements are presented for uniquely prepared YBa₂Cu₃OD₆₊̮̮y single crystals in which a non-local normal fluid response is expected. The resonant cavity probe designed for measurement of T1-2201 single crystals operates in the TMolo mode such that the sample is located at a magnetic field node and electric field antinode. A dual-sapphire hot-finger technique was developed for supporting the sample in the electric field of the cavity, and non-perturbative issues associated with this technique were addressed. A dielectric layer resulting from the degradation of sample outer surfaces was identified as a significant source of dielectric loss. The dimensional dependence of this loss was treated theoretically and etching was shown to drastically reduce this unwanted absorption. The factor currently limiting use of this probe to measure T1-2201 single crystals is absorption by the optical-grade sapphire used to support the sample in the cavity. The loss due to the sapphire is currently on the same order of magnitude as the sample loss to be measured. Employment of premium-grade sapphire plates should significantly reduce this background level and permit accurate measurement of the surface resistance of single crystal T1-2201. YBaD₂Cu₃O₆+y, single crystals have been meticulously prepared with large ;-axis dimensions. This has permitted microwave surface resistance measurements where a magnetic field is applied perpendicular to the CuOz planes, while minimizing demagnetization effects. In this geometry, the electrodynamic response of the normal fluid is expected to be non-local, as the mean free path of the quasiparticles exceeds the penetration depth. R₃(T) measurements were obtained for the crystals using a resonant cavity operating in the TE₀₁₁ mode at 13.4 GHz. No increase in the surface resistance, which is expected for a non-local quasiparticle response, was observed at low temperatures. Possible explanations for this result, and recommendations for further study of these samples are discussed.

description: As a development of arXiv:1912.12897, we note that the ordinary Shiraishi functions have an insufficient number of parameters to describe generic eigenfunctions of double elliptic system (Dell). The lacking parameter can be provided by substituting elliptic instead of the ordinary Gamma functions in the coefficients of the series. These new functions (ELS-functions) are conjectured to be functions governed by compactified DIM networks which can simultaneously play the three roles: solutions to non-stationary Dell equations, Dell conformal blocks with the degenerate field (surface operator) insertion, and the corresponding instanton sums in $6d$ SUSY gauge theories with adjoint matter. We describe the basics of the corresponding construction and make further conjectures about the various limits and dualities which need to be checked to make a precise statement about the Dell description by double-periodic network models with DIM symmetry. We also demonstrate that the ELS-functions provide symmetric polynomials, which are an elliptic generalization of Macdonald ones, and compute the generation function of the elliptic genera of the affine Laumon spaces. In the particular $U(1)$ case, we find an explicit plethystic formula for the $6d$ partition function, which is a non-trivial elliptic generalization of the $(q,t)$ Nekrasov-Okounkov formula from $5d$.

description: In this paper, we propose a new Rydberg entangling gate scheme which we demonstrate theoretically to have an order of magnitude improvement in fidelities and speed over existing protocols. We find that applying this gate to donors in silicon would help overcome the strenuous requirements on atomic precision donor placement and substantial gate tuning, which so far has hampered scaling. We calculate multivalley Rydberg interactions for several donor species using the Finite Element Method, and show that induced electric dipole and Van der Waals interactions, calculated here for the first time, are important even for low-lying excited states. We show that Rydberg gate operation is possible within the lifetime of donor excited states with 99.9% fidelity for the creation of a Bell state in the presence of decoherence.

description: The infrared sky from space is the sum of a cosmic signal from galaxies, quasars, and perhaps more exotic sources; and foregrounds from the Milky Way and from the Solar System. At a distance of 1 AU from the Sun, the foreground from interplanetary dust is very bright between 5 and 100 microns, but ``very bright'' is still several million times fainter than the background produced by ground-based telescopes. In the near infrared 1-2.2 micron range the space infrared sky is a thousand times fainter than the OH nightglow from the Earth's atmosphere. As a result of these advantages, wide-field imaging from space in the infrared can be an incredibly sensitive method to study the Universe.

Causal Paths in Temporal Networks of Face-to-Face Human Interactions
Creators: name: Funel, Agostino
Publisher: name: arXiv
Year: 2020
Subjects: subject: Social and Information Networks (cs.SI)
subject: FOS: Computer and information sciences

description: In a temporal network causal paths are characterized by the fact that links from a source to a target must respect the chronological order. In this article we study the causal paths structure in temporal networks of human face to face interactions in different social contexts. In a static network paths are transitive i.e. the existence of a link from $a$ to $b$ and from $b$ to $c$ implies the existence of a path from $a$ to $c$ via $b$. In a temporal network the chronological constraint introduces time correlations that affects transitivity. A probabilistic model based on higher order Markov chains shows that correlations that can invalidate transitivity are present only when the time gap between consecutive events is larger than the average value and are negligible below such a value. The comparison between the densities of the temporal and static accessibility matrices shows that the static representation can be used with good approximation. Moreover, we quantify the extent of the causally connected region of the networks over time.

The Bounds on Lorentz and CPT Violating Parameters in the Higgs Sector

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

description: In this talk, I discuss possible bounds on the Lorentz and CPT violating parameters in the Higgs sector of the so called minimal standard model extension. The main motivation to this study is coming from the fact that unlike the parameters in the fermion and gauge sector, there are no published bounds on the parameters in the Higgs sector. From the one-loop contributions to the photon propagator the bounds on the CPT-even asymmetric coefficients are obtained and the c_μνcoefficients in the fermion sector determine the bound on the CPT-even symmetric coefficients. The CPT-odd coefficient is bounded from the non-zero vacuum expectation value of the Z-boson.

description: We study various entanglement measures associated with certain non-conformal field theories. We consider non-conformal D$p$-brane backgrounds, which are dual to these field theories, for our holographic analysis. Restricting our interests in $p=1,2,4$, we explicitly compute properties of holographic entanglement entropy and entanglement wedge cross section, $\text{E}_{W}$, corresponding to two parallel strip shaped boundary subregions in these set ups. We study low and high temperature behaviours of these quantities analytically as well as using numerical methods. In all cases, the $\text{E}_{W}$ decrease monotonically with temperature. We observe discontinuous jumps in $\text{E}_{W}$ while the width of (as well as the separation between) the subregions reach critical values in all the cases considered. However, the corresponding holographic mutual information $\texttt{I}_{M}$ continuously decreases to zero for the aforementioned configurations. We also notice that the conjectured inequality $\text{E}_{W} \geq \texttt{I}_{M}/2$ still holds for non-conformal field theories as well. We analytically determine the critical separation between these subregions that triggers a phase transition in the holographic mutual information.

description: Based in Mesopotamia in 1914.

The visitor's father took part in the siege of Kut-el-amara, 1915-6, where the garrison were killed in the siege or died in captivity. The soldiers were surrounded for five months before surrendering. They were then marched 200 miles in 120 degrees Fahrenheit. When they reached the Turkish medics, they decided who was fit enough to continue and who would be kept to be swapped for other prisoners. The interviewee's father was declared unfit and left at the checkpoint. Two friends who had supported him on the march were declared fit and later died.

He returned from India in 1919, having been sent there to recover, and weighed only 5st 6lbs. He then helped to run the poppy appeal until the mid-1950s.
Debye-Huckel theory for two-dimensional Coulomb systems living on a finite surface without boundaries

description: We study the statistical mechanics of a multicomponent two-dimensional Coulomb gas which lives on a finite surface without boundaries. We formulate the Debye--Huckel theory for such systems, which describes the low-coupling regime. There are several problems, which we address, to properly formulate the Debye--Huckel theory. These problems are related to the fact that the electric potential of a single charge cannot be defined on a finite surface without boundaries. One can only define properly the Coulomb potential created by a globally neutral system of charges. As an application of our formulation, we study, in the Debye--Huckel regime, the thermodynamics of a Coulomb gas living on a sphere of radius $R$. We find, in this example, that the grand potential (times the inverse temperature) has a universal finite-size correction $(1/3) \ln R$. We show that this result is more general: for any arbitrary finite geometry without boundaries, the grand potential has a finite-size correction $(χ/6) \ln R$, with $χ$ the Euler characteristic of the surface and $R^2$ its area.
The X(3872) tetraquarks in B and B_s decays

description: We discuss how the latest data on X(3872) in B and B_s decays speak about its tetraquark nature. The established decay pattern, including the up to date observations by CMS, are explained by the mixing of two quasi-degenerate, unresolvable, neutral states. The same mechanism also explains isospin violations in X decays and strongly suggests that the lurking charged partners are required to have very small branching fractions in J/psi rho^pm, well below the current experimental limits. In addition, a new prediction on the decay into J/psi omega final states is attained. The newest experimental observations are found to give thrust to the simplest tetraquark picture and call for a definitive, in-depth study of final states with charged rho mesons.

title: Analysing the Resolution of Security Bugs in Software Maintenance
Creators: name: Saleem, Saad Bin
Publisher: name: The Open University

description: Security bugs in software systems are often reported after incidents of malicious attacks. Developers often need to resolve these bugs quickly in order to maintain the security of such systems. Bug resolution includes two kinds of activities: triaging confirms that the bugs are indeed security problems, after which fixing involves making changes to the code. It is reported in the literature that, statistically, security bugs are reopened more often compared to others, which poses two new research questions: (a) Are developers “rushing” to triage security bugs too soon under the pressure of deadlines? (b) Do developers need to spend more time fixing security bugs to avoid frequent reopening? This thesis explores these questions in order to determine whether security bug fixing should take a higher priority than other bugs to avoid malicious attackers exploiting vulnerabilities before the problems are fixed, and whether security bug fixing should take a higher priority than other bugs. In this thesis a quantitative approach has been adopted by conducting statistical empirical studies to observe the behaviour of software developers engaged in dealing with security bugs. Firstly, the concept of "rush'' has been borrowed from the time management literature to refer to the behaviour of people delivering work under the pressure of deadlines. By observing how developers deliver bug resolution before the deadline of releases, the degree of rush has been measured as the ratio between the actual time spent by developers during triaging and the theoretical time the developers have by delaying the fixes until the next regular release. In this thesis, a suggest that delaying bug assignment helps find the right developer and gives the developer more time to prepare for the same workload with more relaxed planning constraints. Secondly, to analyse the complexity of security bug fixes, the fan-in complexity of functions relevant to security bugs has been measured, rather than simply measuring the time spent by the software developers on the fixing of such bugs. The first null hypothesis is tested using a Man-Whitney method on five software case studies, Samba, MozillaFirefox, RedHat, FreeBSD and Mozilla. The second null hypothesis is tested by comparing the results of fixing security and non-security bugs from the Samba and MozillaFirefox case studies. Statistically significant results suggest that security bugs are triaged in a rush compared to non-security bugs for RedHat, FreeBSD and Mozilla. In terms of fan-in, the results of the Samba and MozillaFirefox case studies suggest that security bugs are more complex to fix compared to non-security bugs.
Efficient Image Gallery Representations at Scale Through Multi-Task Learning

description: Image galleries provide a rich source of diverse information about a product which can be leveraged across many recommendation and retrieval applications. We study the problem of building a universal image gallery encoder through multi-task learning (MTL) approach and demonstrate that it is indeed a practical way to achieve generalizability of learned representations to new downstream tasks. Additionally, we analyze the relative predictive performance of MTL-trained solutions against optimal and substantially more expensive solutions, and find signals that MTL can be a useful mechanism to address sparsity in low-resource binary tasks.

description: We derive factorization theorems for Lambda_QCD/mb power corrections to inclusive B-decays in the endpoint region, where mX^2 ~mb Lambda_QCD. In B-> Xu e nu our results are for the full triply differential rate. A complete enumeration of Lambda_QCD/mb corrections is given. We point out the presence of new Lambda_QCD/mb-suppressed shape functions, which arise at tree level with a $4 pi$-enhanced coefficient, and show that these previously neglected terms induce an additional large uncertainty for current inclusive methods of measuring |Vub| that depend on the endpoint region of phase space.

description: Social networks include millions of users constantly looking for new relationships for personal or professional purposes. Social network sites recommend friends based on relationship features and content information. A significant part of information shared every day is spread in Hashtags. None of the existing content-based recommender systems uses the semantic of hashtags while suggesting new friends. Currently, hashtags are considered as strings without looking at their meanings. Social network sites group together people sharing exactly the same hashtags and never semantically close ones. We think that hashtags encapsulate some people interests. In this paper, we propose a framework showing how a recommender system can benefit from hashtags to enrich users' profiles. This framework consists of three main components: (1) constructing user's profile based on shared hashtags, (2) matching method that computes semantic similarity between profiles, (3) grouping semantically close users using clustering technics. The proposed framework has been tested on a Twitter dataset from the Stanford Large Network Dataset Collection consisting of 81306 profiles.

description: Concentration in milk production results in an increase in demand for industrial feed mixes used in cow feeding. Concentration processes in Poland are not very well advanced and the average size of cow herd is several times lower than in other EU countries. Domestic use of industrial feed mixes per unit of milk production increases along rising scale of production but is still considerably below the level observed in the EU. In the next years concentration of production will advance a further increase in demand pro industrial feed mixes in the dairy sector is expected.

description: Fermi coordinates are the natural generalization of inertial Cartesian coordinates to accelerated systems and gravitational fields. We study the motion of ultrarelativistic particles and light rays in Fermi coordinates and investigate inertial and tidal effects beyond the critical speed c/sqrt(2). In particular, we discuss the black-hole tidal acceleration mechanism for ultrarelativistic particles in connection with a possible origin for high-energy cosmic rays.
