Essays in macroeconomics
Creators: name: Nadeau, Jean-François
Publisher: name: University of British Columbia
Year: 2009

description: There is growing acknowledgement that changes in expectations are an important cause of the business cycle. Business cycles are characterized by positive co-movements between consumption, investment, output and hours, yet changes in expectations cannot generate such positive co-movements in the most standard neo-classical business cycle model. If one is willing to entertain a richer production technology, it is possible to obtain the kind of fluctuations typical of business cycles that are caused by expectation revisions. This thesis analyzes systematically such a production technology, characterized by a nonlinear transformation curve between consumption and investment at the aggregate level, and evaluate some of its macroeconomic implications. This thesis comprises three essays. The first essay empirically investigates if the proposed change in the production technology improves the capacity of neo-classical business cycle models to account for the behavior of the aggregate labor market. It finds that the proposed change is a partial improvement over standard models. The second essay shows that while a nonlinear transformation curve helps in obtaining an economic expansion following good news about future productivity gains, it can do so only if the intertemporal elasticity of substitution in consumption is high. To obtain an expansion in the more general case, one has to allow for a sufficiently high degree of complementarity between capital and labor in production. The third essays estimates a version of the model to analyze its business cycle properties. In the model, the nonlinear transformation curve arises because some resources need to be spent to distribute goods to their final use. There, it is found that the estimated model reproduces well the dynamics of output and investment but produces too much consumption volatility. Moreover, it suggests that news about future productivity changes are a more important source of economic fluctuation than actual changes in productivity. Finally, the estimated model produces distribution costs that are quite in line with the data.

description: We fit lattice-QCD data for light-pseudoscalar masses and decay constants, from HISQ configurations generated by MILC, to SU(3) staggered chiral perturbation theory. At present such fits have rather high values of chi^2/d.o.f., possibly due to the lack of ensembles with lighter-than-physical sea strange-quark masses. We propose solutions to this problem for future work. We also perform simple linear interpolations near the physical point on two ensembles with different lattice spacings, and obtain the preliminary result (f_K / f_pi)^phys = 1.1872(41) in the continuum limit.

Commuting quantum circuits: efficient classical simulations versus hardness results

description: The study of quantum circuits composed of commuting gates is particularly useful to understand the delicate boundary between quantum and classical computation. Indeed, while being a restricted class, commuting circuits exhibit genuine quantum effects such as entanglement. In this paper we show that the computational power of commuting circuits exhibits a surprisingly rich structure. First we show that every 2-local commuting circuit acting on d-level systems and followed by single-qudit measurements can be efficiently simulated classically with high accuracy. In contrast, we prove that such strong simulations are hard for 3-local circuits. Using sampling methods we further show that all commuting circuits composed of exponentiated Pauli operators e^{iθP} can be simulated efficiently classically when followed by single-qubit measurements. Finally, we show that commuting circuits can efficiently simulate certain non-commutative processes, related in particular to constant-depth quantum circuits. This gives evidence that the power of commuting circuits goes beyond classical computation.

description: We present a random number generation scheme that uses broadband measurements of the vacuum field contained in the radio-frequency sidebands of a single-mode laser. Even though the measurements may contain technical noise, we show that suitable algorithms can transform the digitized photocurrents into a string of random numbers that can be made arbitrarily correlated with a subset of the quantum fluctuations (high quantum correlation regime) or arbitrarily immune to environmental fluctuations (high environmental immunity). We demonstrate up to 2 Gbps of real time random number generation that were verified using standard randomness tests.

description: We investigate the vacancy effects on quasiparticle band structure of graphene near the Dirac point. It is found that each Dirac nodal point splits into two new nodal points due to the coherent scattering among vacancies. The splitting energy between the two nodal points is proportional to the square root of vacancy concentration. In addition, an extra dispersionless impurity band of zero energy due to particle-hole symmetry is found. Our theory offers an excellent explanation to the recent experiments.
Genuine Many-Body Quantum Scars along Unstable Modes in Bose-Hubbard Systems

description: The notion of many-body quantum scars is associated with special eigenstates, usually concentrated in certain parts of Hilbert space, that give rise to robust persistent oscillations in a regime that globally exhibits thermalization. Here we extend these studies to many-body systems possessing a true classical limit characterized by a high-dimensional chaotic phase space, which are not subject to any particular dynamical constraint. We demonstrate genuine quantum scarring of wave functions concentrated in the vicinity of unstable classical periodic mean-field modes in the paradigmatic Bose-Hubbard model. These peculiar quantum many-body states exhibit distinct phase-space localization about those classical modes. Their existence is consistent with Heller’s scar criterion and appears to persist in the thermodynamic long-lattice limit. Launching quantum wave packets along such scars leads to observable long-lasting oscillations, featuring periods that scale asymptotically with classical Lyapunov exponents, and displaying intrinsic irregularities that reflect the underlying chaotic dynamics, as opposed to regular tunnel oscillations.
Routes to remarriage and subsequent (re)marital quality : does how you get there really matter?
Creators: name: Koren, Tamara
Publisher: name: University of British Columbia
Year: 2009

description: Remarriage is a growing phenomenon that has reached an all-time high within the past few decades. While research on the marital quality of remarried couples has become common, existing remarriage literature has endlessly assessed remarried couples as a united and cohesive group, failing to distinguish between the various forms and complexities. Due to this lack of research, this study aims to investigate various forms of remarriage (e.g. serial/higher order marriage, remarriage through widowhood or divorce, and postmarital cohabitation as recoupling) in terms of relationship quality in order to clearly show that remarriage is not a simple union, but rather a complex form. Compared to those with a lower number of previous marriages, remarried persons who have a higher past number of marriages were hypothesized to experience lower marital quality. Widowers who remarry are also hypothesized to encompass higher levels of marital quality when compared to those who divorced and then remarried. And finally, persons who chose to cohabit post-divorce were compared to remarried persons, as a pure exploratory analysis. To assess marital quality three dimensions that have been well documented are used: divorce attitudes, marital interaction, and disagreements. Using the Canadian General Social Survey cycle 15: family history data set, logistic regression analyses are used for the two binary dependent variables (divorce attitudes and marital interaction) whereas multiple regression is used for the disagreement dependent variable. Overall findings indicated no support for any of the hypotheses once the control variables were added, however, postmarital cohabitors differed from remarried persons in terms of likelihood of divorce/breakup; there were no other significant differences between these groups. This study helped to explore a different way of looking at remarriage and these results suggest that more research is needed in order to investigate these variations of remarried unions on experiences of marital quality.
Modelling and simulation of interdependencies between the communication and information technology infrastructure and other critical infrastructures
Creators: name: Abdur Rahman, Hafiz Md.
Publisher: name: University of British Columbia
Year: 2009

description: Critical infrastructures are the lifelines of modern societies. The Communication and Information Technology Infrastructure (CITI) provides the basic mechanisms for sharing control and decision-making information among different critical infrastructures. Failures in CITI, either due to an accident or malicious action can propagate to other infrastructures and degrade or disrupt their functionality. Conversely, failures in other infrastructures can also propagate to CITI and hence disrupt the operation of many of the interconnected systems. For reliable and consistent operation of critical infrastructure networks, it is important to have tools and techniques to model and simulate CITI related interdependencies. This research is focusing on developing such methods and tools for CITI interdependency modelling and simulation. Our approach is based on system engineering techniques, where critical infrastructures are viewed as a system of systems. Interdependencies between different system components are captured using precise mathematical functions. As such, our approach goes beyond the limitations of agent-based modelling and simulation paradigms, where interdependencies are considered an emergent behavior. In this research, we have used predictive modelling techniques commonly used in power systems, data communication networks and information systems. The approach is based on results from real CITI interdependency related data. In our model, we used these data to identify the origin of different types of CITI failure and their impacts on critical infrastructures. Following that, we developed techniques to estimate interdependencies between CITI and other critical infrastructures. Finally, we developed techniques to simulate CITI interdependencies in a critical infrastructures simulator. The simulation results were validated against real-life failure cases. Our approach gives a comprehensive solution to CITI interdependency modelling and simulation problems and hence is an important step in the critical infrastructure related research. Even though our techniques are developed for CITI interdependency, they will be useful for other critical infrastructure networks as well.

description: Sustainability is a business strategy combining economic, social, and environmental issues. This paper examines the corporate governance and sustainability literature. So we consider a new bibliometric database focusing on the network of keywords appearing in the literature. The quantitative approach is also new: we combine the information from different community detection algorithms to find the most important results and relationships in the literature. The final results show that the literature on corporate governance and sustainability raises an essential strategic question: for long-term sustainability if there needs to be a strong link between stakeholders and corporate social responsibility (CSR). So, considering a company’s actions’ social, economic, and environmental effects can help figure out how much corporate responsibility is needed. Also, companies that consider CSR and sustainability in their businesses find it easier to keep long-term relationships with customers, employees, and other stakeholders, which can be considered vital. Last, a strategic view of corporate governance should emphasize the importance of intellectual capital and the Triple-Bottom-Line approach to sustainable growth in a strategic view of corporate governance. In this sense, a more wholesome view of value creation aims to provide companies with better financial results while also serving society’s environment and social well-being. By addressing these issues, governments and other groups can make the business world more sustainable and responsible.

Turán H-densities for 3-graphs

Year: 2012
Subjects: subject: Combinatorics (math.CO)

description: Given an $r$-graph $H$ on $h$ vertices, and a family $\mathcal{F}$ of forbidden subgraphs, we define $\ex_{H}(n, \mathcal{F})$ to be the maximum number of induced copies of $H$ in an $\mathcal{F}$-free $r$-graph on $n$ vertices. Then the \emph{Turán $H$-density} of $\mathcal{F}$ is the limit \[π_{H}(\mathcal{F})= \lim_{n\rightarrow \infty}\ex_{H}(n, \mathcal{F})/\binom{n}{h}. \] This generalises the notions of \emph{Turán density} (when $H$ is an $r$-edge), and \emph{inducibility} (when $\mathcal{F}$ is empty). Although problems of this kind have received some attention, very few results are known. We use Razborov's semi-definite method to investigate Turán $H$-densities for 3-graphs. In particular, we show that \[π_{K_4^-}(K_4) = 16/27,\] with Turán's construction being optimal. We prove a result in a similar flavour for $K_5$ and make a general conjecture on the value of $π_{K_t^-}(K_t)$. We also establish that \[π_{4.2}(\emptyset)=3/4,\] where 4.2 denotes the 3-graph on 4 vertices with exactly 2 edges. The lower bound in this case comes from a random geometric construction strikingly different from previous known extremal examples in 3-graph theory. We give a number of other results and conjectures for 3-graphs, and in addition consider the inducibility of certain directed graphs. Let $\vec{S}_k$ be the \emph{out-star} on $k$ vertices; i.e{.} the star on $k$ vertices with all $k-1$ edges oriented away from the centre. We show that \[π_{\vec{S}_3}(\emptyset)=2\sqrt3-3,\] with an iterated blow-up construction being extremal. This is related to a conjecture of Mubayi and Rödl on the Turán density of the 3-graph $C_5$. We also determine $π_{\vec{S}_k}(\emptyset)$ when $k=4$, and conjecture its value for general $k$.

Statistical methods for high throughput genomics
Creators: name: Lo, Chi Ho
Publisher: name: University of British Columbia
Year: 2009

description: The advancement of biotechnologies has led to indispensable high-throughput techniques for biological and medical research. Microarray is applied to monitor the expression levels of thousands of genes simultaneously, while flow cytometry (FCM) offers rapid quantification of multi-parametric properties for millions of cells. In this thesis, we develop approaches based on mixture modeling to deal with the statistical issues arising from both high-throughput biological data sources. Inference about differential expression is a typical objective in analysis of gene expression data. The use of Bayesian hierarchical gamma-gamma and lognormal-normal models is popular for this type of problem. Some unrealistic assumptions, however, have been made in these frameworks. In view of this, we propose flexible forms of mixture models based on an empirical Bayes approach to extend both frameworks so as to release the unrealistic assumptions, and develop EM-type algorithms for parameter estimation. The extended frameworks have been shown to significantly reduce the false positive rate whilst maintaining a high sensitivity, and are more robust to model misspecification. FCM analysis currently relies on the sequential application of a series of manually defined 1D or 2D data filters to identify cell populations of interest. This process is time-consuming and ignores the high-dimensionality of FCM data. We reframe this as a clustering problem, and propose a robust model-based clustering approach based on t mixture models with the Box-Cox transformation for identifying cell populations. We describe an EM algorithm to simultaneously handle parameter estimation along with transformation selection and outlier identification, issues of mutual influence. Empirical studies have shown that this approach is well adapted to FCM data, in which a high abundance of outliers and asymmetric cell populations are frequently observed. Finally, in recognition of concern for an efficient automated FCM analysis platform, we have developed an R package called flowClust to automate the gating analysis with the proposed methodology. Focus during package development has been put on the computational efficiency and convenience of use at users' end. The package offers a wealth of tools to summarize and visualize features of the clustering results, and is well integrated with other FCM packages.

description: While societal events often impact people worldwide, a significant fraction of events has a local focus that primarily affects specific language communities. Examples include national elections, the development of the Coronavirus pandemic in different countries, and local film festivals such as the César Awards in France and the Moscow International Film Festival in Russia. However, existing entity recommendation approaches do not sufficiently address the language context of recommendation. This article introduces the novel task of language-specific event recommendation, which aims to recommend events relevant to the user query in the language-specific context. This task can support essential information retrieval activities, including web navigation and exploratory search, considering the language context of user information needs. We propose LaSER, a novel approach toward language-specific event recommendation. LaSER blends the language-specific latent representations (embeddings) of entities and events and spatio-temporal event features in a learning to rank model. This model is trained on publicly available Wikipedia Clickstream data. The results of our user study demonstrate that LaSER outperforms state-of-the-art recommendation baselines by up to 33 percentage points in MAP@5 concerning the language-specific relevance of recommended events.
Acceptance of Chinese latecomers' technological contributions in international ICT standardization — The role of origin, experience and collaboration

description: As technical standards are an important part of China's industrial transformation towards an innovation-driven economy, Chinese organizations have started to deploy substantial resources in recent years to take on a leading role in international ICT standardization. However, many Chinese organizations experience, similar to other latecomers to standardization, limited success when contributing to standardization processes, a phenomenon also referred to as the standardization gap. The literature on standardization to date has paid little attention to how Chinese latecomers enter and influence international standardization processes that have traditionally been shaped by organizations from industrialized countries. We therefore analyze the country-of-origin effect as well as factors such as experience and collaboration for successful contributions of Chinese organizations to standards. Using data from the Third Generation Partnership Project (3GPP) and binary logistic regression analysis, we are able to show that, in our sample, contributions from Chinese latecomers are significantly less likely to be accepted than those from more established actors from industrialized economies. Moreover, our findings indicate that experience is closely associated with success in international ICT standardization, but not moderated by national origin. Therefore, Chinese latecomers might not be able to catch up if they move at the same pace as established competitors. They need to find a way to leapfrog extensive development steps, narrow the standardization capability gap, and thus strengthen their participation and influence. One way to do so might be through strategic collaboration, as our results suggest that Chinese organizations benefit more from collaborating with organizations from more established regions than vice versa, on which we call for further research to establish the causal mechanisms.

description: The Galactic X-ray transient XTE J1752-223 was shown to have properties of black hole binary candidates. As reported in our previous paper, we identified transient and decelerating ejecta in multi-epoch Very Long Baseline Interferometry (VLBI) observations with the European VLBI Network (EVN) and the NRAO Very Long Baseline Array (VLBA). Here we present new EVN and VLBA data in which a new transient ejection event and later a stationary component are identified. The latter is interpreted as a reappearance of the radio core/compact jet during the transition from soft to hard X-ray state. This component appears to be highly variable in brightness although effects of tropospheric instabilities might play a role too. We also re-analyze the earlier VLBI data and find that the transient ejecta closer to the core position has significantly higher proper motion, further strengthening the case for strongly decelerating ejecta on the scale of several hundred milli-arcsecond, never observed in X-ray binaries before. Although the distance of the source is not well constrained, it is clear that these ejectas are at least mildly relativistic at the early stages. Moreover, we show the large scale environment of the transient from the Westerbork synthesis array data recorded in parallel during the EVN run.

Wandering the streets of "Baghdad" : space, representation, and the colonial present
Creators: name: Attewell, Wesley
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis, I will explore the triangular relationship between space, representational practices, and the colonial present. I will grapple with a few key research questions: how do we, as Westerners, represent the “other”? How, in turn, do we represent “ourselves”? How have these representational practices shaped the conduct of the War on Terror? And finally, how are (neo)colonial struggles over the politics of representation intricately bound up with questions of geography? By focusing my attention upon the recent invasion, and subsequent occupation of Iraq, I hope to offer a historico-geographically responsible, as well as anti-essentialist, reading of three distinct “digital spaces”: two blogs (Riverbend’s Baghdad Burning and Colby Buzzell’s My War: Killing Time in Iraq) and Multi-National Force Iraq’s YouTube channel. Here, I will argue that, to paraphrase Edward Said, broader geographical struggles, over forms, over images, and over imaginings are not only being dispersed around the globe, they are also being fractured and subsequently contested on a more micro-scale in these new digital battlegrounds. As I hope to demonstrate over the course of this thesis, social media websites such as blogs and YouTube must conceptualized not only as political, but also as antipolitical spaces, in that they both encourage and stifle critical debate on issues pertaining to late modern warfare. Furthermore, the discursive dimensions of geographical struggle must be brought into (vexed) relation with its material dimensions (i.e., armies moving across space), and it is the mutually constitutive nature of this relationship that I will emphasize in this thesis: in other words, the conduct of late modern warfare is not only influenced by, but also influences, the deployment of representational practices. Ultimately, I argue that the increasing importance of the so-called “social media” (i.e., blogs, YouTube, Facebook, Twitter, etc.) as digital spaces of (anti?)politics enables us, as critical human geographers, to produce a genuinely human geography, and to think about space, the body, and representational practices in very different ways.

description: The propagation of Langmuir waves in plasmas is known to be sensitive to density fluctuations. Such fluctuations may lead to the coexistence of wave pairs that have almost opposite wave-numbers in the vicinity of their reflection points. Using high frequency electric field measurements from the WIND satellite, we determine for the first time the wavelength of intense Langmuir wave packets that are generated upstream of the Earth's electron foreshock by energetic electron beams. Surprisingly, the wavelength is found to be 2 to 3 times larger than the value expected from standard theory. These values are consistent with the presence of strong inhomogeneities in the solar wind plasma rather than with the effect of weak beam instabilities.

description: Transitions between centre sectors are related to confinement in pure Yang-Mills theories. We study the impact of these transitions in QCD-like theories for which centre symmetry is explicitly broken by the presence of matter. For low temperatures, we provide numerical evidence that centre transitions do occur with matter merely providing a bias towards the trivial centre sector until centre symmetry is spontaneously broken at high temperatures. The phenomenological consequences of these transitions for dense hadron matter are illustrated in an SU(3) effective quark theory: centre dressed quarks undergo condensation due to Bose-type statistics forming a hitherto unknown state of dense but cold quark matter.

description: Active trailing-edge technology is a promising application for localized load alleviation of large-diameter wind turbine rotors, accomplished using one or more control surfaces in the rotor blade's outer region. This work focuses on identifying noise contributions from the flap side-edge and the trailing edge in a laboratory condition. Measurements were conducted in the Acoustic Wind Tunnel Braunschweig (AWB) at the German Aerospace Center's (DLR) Braunschweig site. The small-scale model has a span of 1,200 mm and a chord length of 300 mm. The control surface, a plain flap, has a span of 400 mm and a chord length of 90 mm. Far-field noise was measured using a phased-microphone array for various flow speeds, angles of attack, and flap deflection angles. Due to the size of the model and assumed closeness of the sound sources, two noise reduction addons were installed interchangeably: trailing-edge brush and flap side-edge porous foam for sound source identification. Analysis of the far-field noise reveals that, while changes to the flap deflection angle alter the far-field noise spectra, the trailing-edge noise remains the predominant noise source at deflection angles (Formula presented.) and (Formula presented.). No additional noise level was observed from the flap side edge within the measurable frequency range at these angles. The flap side-edge noise has an increased role for frequency larger than 2 kHz for the larger flap deflection angles of (Formula presented.) and (Formula presented.).

description: This paper develops the new concept of the geography of placemories as a critical approach for deciphering spatialised memories in cultural geography. In referring to Alfred North Whitehead’s philosophy of organism and cultural materialism in line with Raymond Williams, the paper reflects on processual conceptions of feeling, society, memory and place. First, reviewing existing research on memory and place elucidates that cultural geography takes spatialised memories as fixed objects. Its analysis leads to statements about society. Second, to avoid this fallacy, the paper shifts the analytical basis for the cultural geographical conception of memorial sites from place to feelings and experiences by developing a new view on spatialised memory. The resulting processual problematisation of the ontology of memories, as well as its relevance for the present and spatialisations, is called the placemoric approach. The analysis of contested remembering processes with regard to the prerogative of interpretation of half-timbered houses in descriptions of Nuremberg’s old town in North Bavaria, Germany demonstrates the capabilities of the placemoric approach. In doing so, the paper shows how spatialised memories are the socially constructed result of permanently changing feelings.

description: We give a proof that Brakke's mean curvature flow under the unit density assumption is smooth almost everywhere in space-time. More generally, if the velocity is equal in a weak sense to its mean curvature plus some given α-Hölder continuous vector field, then we show C^{2,α} regularity almost everywhere.

An Approach to Provide Security in Mobile Ad-Hoc Networks Using Counter Mode of Encryption on Mac Layer

Subjects: subject: Networking and Internet Architecture (cs.NI)
subject: FOS: Computer and information sciences

description: Security in any of the networks became an important issue in this paper we have implemented a security mechanism on Medium Access Control layer by Assured Neighbor based Security Protocol to provide authentication and confidentiality of packets along with High speed transmission for Ad hoc networks. Here we have divided the protocol into two different parts. The first part deals with Routing layer information; in this part we have tried to implement a possible strategy for detecting and isolating the malicious nodes. A trust counter for each node is determined which can be actively increased and decreased depending upon the trust value for the purpose of forwarding the packets from source node to destination node with the help of intermediate nodes. A threshold level is also predetermined to detect the malicious nodes. If the value of the node in trust counter is less than the threshold value then the node is denoted 'malicious'. The second part of our protocol deals with the security in the link layer. For this security reason we have used CTR (Counter) approach for authentication and encryption. We have simulated all our strategies and schemes in NS-2, the result of which gives a conclusion that our proposed protocol i.e. Assured Neighbor based Security Protocol can perform high packet delivery against various intruders and also packet delivery ratio against mobility with low delays and low overheads.

Supersymmetric large-order perturbation with the Nicolai map

Subjects: subject: Supersymmetric

subject: Nicolai map
subject: Dewey Decimal Classification::500 | Naturwissenschaften::530 | Physik

description: In rigidly supersymmetric quantum theories, the Nicolai map allows one to turn on a coupling constant (from zero to a finite value) by keeping the (free) functional integration measure but subjecting the fields to a particular nonlocal and nonlinear transformation. A recursive perturbative construction of the Nicolai-transformed field configuration expresses it as a power series in the coupling, with its coefficient function at order n being a sum of particular tree diagrams. For a quantum-mechanical example, the size of these tree diagrams (under a certain functional norm) is estimated by the (n+1)st power of the field size, and their number grows like n−3/2×4.967n. Such an asymptotic behaviour translates to a finite convergence radius for the formal perturbative expansion of the Nicolai map, which establishes its non-perturbative existence. The known factorial growth of the number of Feynman diagrams for quantum correlators is reproduced by the combinatorics of free-field Wick contractions as usual. We expect our results to extend to higher dimensions, including super Yang–Mills theory.
Quark confinement mechanism and the scale $Λ_{QCD}$

description: The confinement mechanism proposed earlier by the author is applied to problem of arising the so-called scale $Λ_{QCD}$ within the framework of QCD. The natural physical assumption consists of that $1/Λ_{QCD}\,\sim\,$ where $$ is a characteristic size of hadron (radius of confinement). The above confinement mechanism allows us to calculate $$ for mesons in terms of quark and gluonic degrees of freedom and this permits to conclude that $Λ_{QCD}$ should slightly change from hadron to hadron.

description: The analysis of many problems of interest associated with Markov chains, e.g. stationary distributions, moments of first passage time distributions and moments of occupation time random variables, involves the solution of a system of linear equations involving I - P, where P is the transition matrix of a finite, irreducible, discrete time Markov chain. Generalized inverses play an important role in the solution of such singular sets of equations. In this presentation we survey the application of generalized matrix inverses to the aforementioned problems.
