description: Ecological footprint is a method of measuring how much we use the natural resources and how much the nature provides services for human beings. This paper summarized the application of ecological footprint at different scales and in different fields and different ecological types at home and abroad, analyzed the advantages and disadvantages of ecological footprint method, and made a prediction of the application of ecological footprint.
Lines in the sound : a regional approach to windfarm design and visualization in Howe Sound
Creators: name: Flanders, David
Publisher: name: University of British Columbia
Year: 2011

description: Windfarming can provide a reliable, renewable source of energy; its visible presence in the landscape can generate heightened awareness of energy use and sources. Sensitive integration of the technology with the environment is important for promoting sustainability in the region; it must also address public concern for visual quality. This study addresses the siting and design issues raised by proposed windfarms. Three windfarm design scenarios are thus developed and visualized in 3D within the region of Howe Sound, including the town of Squamish, British Columbia. A number of North American and European precedents are examined in terms of public education and acceptance, visual impacts, arrangement and public involvement. Initially, eleven sites within the region are considered in total, based on stakeholder, community and expert analysis. Site analysis is composed of a wind resource and visual inventory, and viewshed analysis. This highlights the strengths and weaknesses of the potential sites. A series of principles identify cultural, aesthetic and pragmatic rationale to guide the site selection process, and evaluating certain sites and designs as being better or worse than others. Design criteria which are explicit and measurable are developed for these principles, providing targets for site selection, informing design process and serving as a baseline for design analysis. Three favourable sites that will best cater to these motivations are selected for windfarm design and visualization. These designs are quantitatively and qualitatively assessed based on their adherence to the design criteria, and are ranked according to how well they satisfy the aesthetic, cultural and pragmatic principles for windfarming. A set of final recommendations for Squamish are offered that will facilitate planning and help to build citizen awareness building process for development of a wind resource industry in the region.

description: We present a way of directly manipulating an arbitrary qubit, without the exchange of any particles. This includes as an application the exchange-free preparation of an arbitrary quantum state at Alice by a remote classical Bob. As a result, we are able to propose a protocol that allows one party to directly enact, by means of a suitable program, any computation exchange-free on a remote second party's unknown qubit. Further, we show how to use this for the exchange-free control of a universal two-qubit gate, thus opening the possibility of directly enacting any desired algorithm remotely on a programmable quantum circuit.

description: We present the theory for ultracold atomic gases in an optical lattice near a Feshbach resonance. In the single-band approximation the theory describes atoms and molecules which can both tunnel through the lattice. Moreover, an avoided crossing between the two-atom and the molecular states occurs at every site. We determine the microscopic parameters of the generalized Hubbard model that describes this physics, using the experimentally known parameters of the Feshbach resonance in the absence of the optical lattice. As an application we also calculate the zero-temperature phase diagram of an atomic Bose gas in an optical lattice.

description: Recently a certain conceptual puzzle in the AdS/CFT correspondence, concerning the growth of quantum circuit complexity and the wormhole volume, has been identified by Bouland-Fefferman-Vazirani and Susskind. In this note, we propose a resolution of the puzzle and save the quantum Extended Church-Turing thesis by arguing that there is no computational shortcut in measuring the volume due to gravitational backreaction from bulk observers. A certain strengthening of the firewall puzzle from the computational complexity perspective, as well as its potential resolution, is also presented.

description: In spring, summer, autumn 2015, we studied the seasonal variation of phytoplankton community structure in six rivers within Duobukuer Nature Reserve, and made preliminary evaluation of the water quality in Duobukuer Nature Reserve based on phytoplankton diversity. The results showed that a total of 7 phyla, 41 genera, 66 species and varieties of phytoplankton were identified in Duobukuer Nature Reserve; the annual species composition was dominated by diatom (59%) which also preponderated in dominant species (84.3%), biomass (68%) and abundance (75%), with no significant seasonal variation. Shannon-Wiener diversity index (H') and Pielou evenness index (J) were used to evaluate the water quality in 13 sampling points, and the results showed that the water quality was good in Duobukuer Nature Reserve, the sampling points 5, 6 and 12 presented β-pollution, and other sampling points were in an oligosaprobic-clean state.

description: We present ultraviolet spectra from the Space Telescope Imaging Spectrograph (STIS) of 12 early B-type stars in the Small Magellanic Cloud (SMC), comprising 9 supergiants and 3 giants. A morphological comparison with Galactic analogues is made using archival data from the International Ultraviolet Explorer (IUE). In general, the intensity of the P Cygni emission in the UV resonance lines is greater, and seen to later spectral types, in the Galactic spectra than in their metal-deficient SMC counterparts; we attribute these effects as most likely arising from weaker stellar winds in the SMC targets, as predicted by radiatively driven wind theory. We also include unpublished STIS observations of two late O-type stars in the SMC. In combination with the B-type observations, and published O-type data, we now have an extensive ultraviolet spectral library of metal-deficient stars, of use in the study of unresolved starbursts and high redshift, star-forming galaxies. In this context, we present empirical measurements for the B-type spectra of the new `1978 index' suggested by Rix et al. as a probe of metallicity in such systems.

description: Canonical Feynman integrals are of great interest in the study of scattering amplitudes at the multi-loop level. We propose to construct $d\log$-form integrals of the hypergeometric type, treat them as a representation of Feynman integrals, and project them into master integrals using intersection theory. This provides a constructive way to build canonical master integrals whose differential equations can be solved easily. We use our method to investigate both the maximally cut integrals and the uncut ones at one and two loops, and demonstrate its applicability in problems with multiple scales.

description: Mit der Einführung eines neuen Protokolls zur Regelung der Kommunikation zwischen Computern und Netzwerken ergibt sich die Notwendigkeit, die zugrundeliegenden Konzepte und deren Umsetzung zu analysieren. IPv6 wies ursprünglich eine große Zahl an Veränderungen im Vergleich zu IPv4 auf, zum Beispiel wurde IPSec verpflichtend für alle Umsetzungen vorgeschrieben. Einige dieser Änderungen konnten sich jedoch nicht durchsetzen. Diese Diplomarbeit evaluiert den aktuellen Stand der Technik im Hinblick auf Werkzeuge zur Überprüfung von Systemen auf Sicherheit im Bereich IPv6 und wendet diese Werkzeuge dann auf aktuelle Umsetzungen von IPv6 Kommunikationsschnittstellen an. Zu diesem Zweck wurde ein Versuchsnetzwerk aufgebaut. Die gewonnenen Daten wurden ausgewertet und geben wertvolle Hinweise zum aktuellen Entwicklungsstand von IPv6. Die Arbeit schließt mit dem Ergebnis, dass IPv6, obwohl noch einiges an Arbeit in diesem Feld vonnöten ist, vom Sicherheitsstandpunkt aus einsatzbereit ist. Zukünftige Forschung in diesem Bereich sollte eine Ergründung der Ursachen der gefundenen Schwachstellen und das Durchführen von Tests in komplexeren Umgebungen umfassen.
description: The introduction of a new basis for addressing and handling communication between networking nodes necessitates the analysis of these concepts and protocols. IPv6 was initially constructed with a huge amount of conceptual changes from IPv4, including the mandatory addition of IPSec. Some of these changes have made it to implementation level, while others have been dropped. This thesis evaluates the current state of the testing software available for IPv6 security analysis and proceeds by performing tests on the network stacks of current operating systems. This work will be facilitated by a laboratory setup specifically for this purpose. Evaluation of the data gained through this approach provides valuable information concerning the current state of IPv6. The thesis ends with the conclusion that, although there is still work to be done, IPv6 is ready to be deployed from an endpoint security point of view. Possible fields of future work include precise analysis of the reasons for discovered vulnerabilities, for example through source code review, and testing in contexts offering a higher level of complexity.
The effect of tooth age on the fracture toughness of four dental bonding systems

Publisher: name: University of British Columbia
Year: 2011

description: Objective: The purpose of this in vitro study was to evaluate the effect of dentin age on the fracture toughness (Kic) of dental bonding systems using the notchless triangular prism (NTP) specimen Kic test. Methods: 80 human molars and pre-molars, 40 of them from patients not older than 45 years ("young") and 40 from patients not younger than 65 years ("old"), were wet ground on 600-grit silicon carbide abrasive paper to obtain a 4x4x4x4mm triangular prisms with the labial surface exposed for bonding. Within each of the two groups, the specimens were randomly assigned to four subgroups (n=10) according to the bonding system to be used for composite bonding: Adper Prompt L-pop (3M ESPE), Clearfil SE (Kuraray), Prime & Bond NT (Dentsply) and Scotch Bond MP (3M ESPE). The composite, Z-100 (3M ESPE), was bonded to each of the treated surfaces as per the manufacturer's instructions to obtain a 4x4x4x8mm dentin-composite NTP specimens. The specimens were stored in water for 24h at 37°C and tested to determine Kic. The data was analyzed using Levene's test for normality, two-way univariate analysis of variance (ANOVA), and Bonferroni tests for multiple means comparisons. A significance level of 0.05 was used for all tests. Results: While Adper Prompt L-pop and Clearfil SE achieved the highest Kic values for both age groups, Prime & Bond NT showed the lowest values. SEM observations of fractured samples revealed differences in fracture path. No statistically significant differences were observed between age groups. Conclusions: The Kic values of the four dental bonding systems were not affected by age. Furthermore, statistically significant differences were observed between the Kic values of the four bonding systems, regardless of the age of the dentin.
Time-Scales for Nonlinear Processes in Preheating after Multifield Inflation with Nonminimal Couplings

description: We have conducted extensive lattice simulations to study the post-inflation dynamics of multifield models involving nonminimal couplings. We explore the parameter dependence of preheating in these models and describe the various time-scales that control such nonlinear processes as energy transfer, re-scattering, and the approach to radiation-domination and thermalization. In the limit of large nonminimal couplings ($ξ_I \sim 100$), we find that efficient transfer of energy from the inflaton condensate to radiative degrees of freedom, emergence of a radiation-dominated equation of state, and the onset of thermalization each consistently occur within $N_{\rm reh} \lesssim 3$ $e$-folds after the end of inflation, largely independent of the values of the other couplings in the models. The exception is the case of negative ellipticity, in which there is a misalignment between the dominant direction in field-space along which the system evolves and the larger of the nonminimal couplings $ξ_I$. In those cases, the field-space-driven parametric resonance is effectively shut off. More generally, the competition between the scalar fields' potential and the field-space manifold structure can yield interesting phenomena such as two-stage resonances. Despite the explosive particle production, which can lead to a quick depletion of the background energy density, the nonlinear processes do not induce any super-horizon correlations after the end of inflation in these models, which keeps predictions for CMB observables unaffected by the late-time amplification of isocurvature fluctuations. Hence the excellent agreement between primordial observables and recent observations is preserved for this class of models, even when we consider post-inflation dynamics.

Covariate Balancing Based on Kernel Density Estimates for Controlled Experiments
Creators: name: Li, Yiou

Publisher: name: arXiv
Year: 2020

description: Controlled experiments are widely used in many applications to investigate the causal relationship between input factors and experimental outcomes. A completely randomized design is usually used to randomly assign treatment levels to experimental units. When covariates of the experimental units are available, the experimental design should achieve covariate balancing among the treatment groups, such that the statistical inference of the treatment effects is not confounded with any possible effects of covariates. However, covariate imbalance often exists, because the experiment is carried out based on a single realization of the complete randomization. It is more likely to occur and worsen when the size of the experimental units is small or moderate. In this paper, we introduce a new covariate balancing criterion, which measures the differences between kernel density estimates of the covariates of treatment groups. To achieve covariate balance before the treatments are randomly assigned, we partition the experimental units by minimizing the criterion, then randomly assign the treatment levels to the partitioned groups. Through numerical examples, we show that the proposed partition approach can improve the accuracy of the difference-in-mean estimator and outperforms the complete randomization and rerandomization approaches.

We examine optimal experimental setups to achieve it by solving Bogoliubov-de Gennes equation both for idealized one-dimensional and realistic three-dimensional cases. The spontaneous modulation of this superfluid is shown to be directly imaged as the density profiles either by optical absorption or by Stern-Gerlach experiments.

description: In this work, we extend the recently proposed adaptive phase field method to model fracture in orthotropic functionally graded materials (FGMs). A recovery type error indicator combined with quadtree decomposition is employed for adaptive mesh refinement. The proposed approach is capable of capturing the fracture process with a localized mesh refinement that provides notable gains in computational efficiency. The implementation is validated against experimental data and other numerical experiments on orthotropic materials with different material orientations. The results reveal an increase in the stiffness and the maximum force with increasing material orientation angle. The study is then extended to the analysis of orthotropic FGMs. It is observed that, if the gradation in fracture properties is neglected, the material gradient plays a secondary role, with the fracture behaviour being dominated by the orthotropy of the material. However, when the toughness increases along the crack propagation path, a substantial gain in fracture resistance is observed.

description: We propose a novel framework to produce cartoon videos by fetching the color information from two input keyframes while following the animated motion guided by a user sketch. The key idea of the proposed approach is to estimate the dense cross-domain correspondence between the sketch and cartoon video frames, and employ a blending module with occlusion estimation to synthesize the middle frame guided by the sketch. After that, the input frames and the synthetic frame equipped with established correspondence are fed into an arbitrary-time frame interpolation pipeline to generate and refine additional inbetween frames. Finally, a module to preserve temporal consistency is employed. Compared to common frame interpolation methods, our approach can address frames with relatively large motion and also has the flexibility to enable users to control the generated video sequences by editing the sketch guidance. By explicitly considering the correspondence between frames and the sketch, we can achieve higher quality results than other image synthesis methods. Our results show that our system generalizes well to different movie frames, achieving better results than existing solutions.

This algorithm allows one to simulate and equilibrate systems with a number of particles two orders of magnitude larger than previous simulations. The phase separation for symmetric binary mixtures is studied for different non-additvities as well as for the Widom-Rowlinson model (B. Widom and J. S. Rowlinson, J. Chem. Phys. 52, 1670 (1970)) in two and three dimensions. The critical densities are determined from finite size scaling. The critical exponents for all the non-additivities are consistent with the Ising universality class.

description: Dirac's approach to gauge symmetries is discussed. We follow closely the steps that led him from his conjecture concerning the generators of gauge transformations {\it at a given time} --to be contrasted with the common view of gauge transformations as maps from solutions of the equations of motion into other solutions-- to his decision to artificially modify the dynamics, substituting the extended Hamiltonian (including all first-class constraints) for the total Hamiltonian (including only the primary first-class constraints). We show in detail that Dirac's analysis was incomplete and, in completing it, we prove that the fulfilment of Dirac's conjecture --in the "non-pathological" cases-- does not imply any need to modify the dynamics. We give a couple of simple but significant examples.

description: Large random matrices appear in different fields of mathematics and physics such as combinatorics, probability theory, statistics, operator theory, number theory, quantum field theory, string theory etc... In the last ten years, they attracted lots of interests, in particular due to a serie of mathematical breakthroughs allowing for instance a better understanding of local properties of their spectrum, answering universality questions, connecting these issues with growth processes etc. In this survey, we shall discuss the problem of the large deviations of the empirical measure of Gaussian random matrices, and more generally of the trace of words of independent Gaussian random matrices. We shall describe how such issues are motivated either in physics/combinatorics by the study of the so-called matrix models or in free probability by the definition of a non-commutative entropy. We shall show how classical large deviations techniques can be used in this context. These lecture notes are supposed to be accessible to non probabilists and non free-probabilists.

description: When a civil war ends there is a formal cessation of hostilities between the warring groups. Yet the termination of fighting does not necessarily end the violence, which can persist into post-war years. The study of post-civil war violence as a distinct phenomenon is dominated by explanations that see it as a legacy of the warring elite and an exercise in preventing them restarting war, or, as culturally embedded within interpersonal relations. This thesis draws on the group nature of civil war to offer a different perspective on this problem. It considers post-civil war violence as a product of continuing hostile relations between previous warring groups and examines the transformation of broader intergroup relations in post-war years. The rationale for the research rests on the idea that if violence is part of intergroup relations, then how might a more informed understanding of these relations facilitate effective peacebuilding interventions in countries emerging from civil war. Using qualitative methods, and a case study approach focusing on Nepal and Mozambique, I compare understandings and experiences of the transformation of intergroup relations from the perspective of political parties that claim to represent the previous warring groups, to that of people living in villages (three in each country). The study finds that violence can remain a central feature of how political parties relate to one another, even after decades of peace. To appreciate this violence requires a conceptual step away from dominant ways of thinking of violence as physical or structural. Conversely, while intergroup violence does not appear to have been a problem within the villages, the presence of violence within interparty relations is driving a pervasive and persistent fear that civil war may once again erupt. The thesis examines the impact of this violence on both the peace process and group relations to highlight the need to recognise and proactively address it.

description: Coxeter matroids generalize matroids just as flag varieties of Lie groups generalize Grassmannians. Valuations of Coxeter matroids are functions that behave well with respect to subdivisions of a Coxeter matroid into smaller ones. We compute the universal valuative invariant of Coxeter matroids. A key ingredient is the family of Coxeter Schubert matroids, which correspond to the Bruhat cells of flag varieties. In the process, we compute the universal valuation of generalized Coxeter permutohedra, a larger family of polyhedra that model Coxeter analogues of combinatorial objects such as matroids, clusters, and posets.

description: This paper quantifies the impact of consumer’s diet-health behaviours on an important health outcome. We use data from the 2007-2008 U.S. NHANES to estimate the impact of dietary supplement intake on respondent’s BMI outcomes, controlling for diet quality using Healthy Eating Index scores. The analysis applies propensity score matching (PSM) to account for selection bias and endogeneity between self-reported diet and health behaviour (treatment) and BMI outcomes. Dietary supplement choices are explained by demographic, lifestyle, food culture and food security variables. Matching results suggest that regular dietary supplement consumption is associated with significant lower BMI outcomes of almost 1 kg/m2.

description: One of the models in the industrial organisation literature considers that firms aim to “hit the jackpot”, i.e., to introduce new products that are successfully uptaken by consumers, and therefore, remain on retailers’ shelves for a long time. This paper studies the implications of such a type of competition for the health agenda aiming at improving the nutritional quality of the available food products focusing on the processed potato products category. The analysis indicates that one should not expect the assortment of products to change and the most effective public policy would be the enforcement of product reformulation.

description: Fast and accurate evaluation of free energy has broad applications from drug design to material engineering. Computing the absolute free energy is of particular interest since it allows the assessment of the relative stability between states without the use of intermediates. In this letter, we introduce a general framework for calculating the absolute free energy of a state. A key step of the calculation is the definition of a reference state with tractable deep generative models using locally sampled configurations. The absolute free energy of this reference state is zero by design. The free energy for the state of interest can then be determined as the difference from the reference. We applied this approach to both discrete and continuous systems and demonstrated its effectiveness. It was found that the Bennett acceptance ratio method provides more accurate and efficient free energy estimations than approximate expressions based on work. We anticipate the method presented here to be a valuable strategy for computing free energy differences.

description: The conditional cash transfer program «Oportunidades» has been implemented in Mexico in order to alleviate intergenerational poverty by investing in human capital through education, health and nutrition. We estimate food and nutrient elasticities of demand with respect to income and price by the virtue of QUAIDS. We find that beneficiary households show a higher diversity of the diet; however, this diversity is not large enough to increment the sources of macro- and micronutrient intake. The value of the beneficiaries’ calorie elasticity also suggests that their need for food may not be entirely satisfied even after the reception of the monetary transfer.

description: High level of trade deficit indicates low competitiveness in B&H agribusiness, which brings the question whether its low competitiveness is mirroring its low market orientation, i.e. capability to apply integrated business philosophy which ensures adequate competitive advantages and sustains development of companies. To answer that, a survey was conducted through a MKTOR scale for measuring market orientation, on fifty food companies in the period May – December 2013. Statistical analysis was done using SPSS, and it included reliability test, exploratory factor analysis and confirmatory factor analysis, along with the tests of statistical significance and descriptive statistics. B&H food companies are only partly market-oriented, 3.430 (max 5.0), with Crombach’s Alpha of 0.943. Factor analysis revealed three market orientation factors: intelligence generation (0.393), intelligence dissemination (0.503) and responsiveness (0.522). Level of market orientation in small (3.511) and large (3.364) was statistically different, meaning that the smaller companies are less capable of understanding the market. Also, small and big companies have significantly different performances on the basis of all three market orientation factors. However, we may say that for both types of companies, intelligence generation and intelligence dissemination are a weak link, whereas responsiveness is better than total average. Results show that food companies in B&H have low ability of collecting key information about the market. Furthermore, omissions in internal organization and lack of knowledge about marketing are barrier to use efficiently the collected, often disorganized data on market necessities. Therefore existing, collected data are not utilized to enhance creative communication and building of added value that will make difference on market place and enable B&H food companies to develop sustainable competitive advantages.
