description: We study bosons loaded in a one-dimensional optical lattice of two-fold $p$-orbital degeneracy at each site. Our numerical simulations find an anti-ferro-orbital p$_x$+ip$_y$, a homogeneous p$_x$ Mott insulator phase and two kinds of superfluid phases distinguished by the orbital order (anti-ferro-orbital and para-orbital). The anti-ferro-orbital order breaks time reversal symmetry. Experimentally observable evidence is predicted for the phase transition between the two different superfluid phases. We also discover that the quantum noise measurement is able to provide a concrete evidence of time reversal symmetry breaking in the first Mott phase.

Emergence of Riemannian manifolds from graphs and aspects of Chern-Simons theory
Creators: name: Chen, Si
Publisher: name: University of British Columbia
Year: 2013

description: This thesis is divided into three chapters. Chapter 1 is a study of statistical models of graphs, in order to explore possible realizations of emergent manifolds. Graphs with given numbers of vertices and edges are considered, governed by a Hamiltonian that favors graphs with near-constant valency and local rotational symmetry. The model is simulated numerically in the canonical ensemble. It is found that the model exhibits a first-order phase transition, and that the low energy states are almost triangulations of two dimensional manifolds. The resulting manifold shows topological "handles" and surface intersections in a higher embedding space as well as non-trivial fractal dimension. The model exhibits a phase transition temperature of zero in the bulk limit. We explore the effects of adding long-range interactions to the model, which restore a finite transition temperature in the bulk limit. In Chapter 2, aspects of Chern-Simons theory are studied. The relations between Chern-Simons theory, a model known as BF theory named after the fields that appear in the actions, and 3D gravity, are explored and generalized to the case of non-orientable spacetime manifolds. U(1) Chern-Simons theory is quantized canonically on orientable manifolds, and U(1) BF theory is similarly quantized on non-orientable manifolds. By requiring the quantum states to form a representation of the deformed holonomy group and the deformed large gauge transformation group, we find that the mapping class group of the spacetime manifold can be consistently represented, provided the prefactor k of the Chern-Simon action satisfies quantization conditions which in general are non-trivial. We also find a k <--> 1/k duality for the representations. Motivated by open questions about interpreting the finite size results from Chapter 1, models of finite size scaling for systems with a first-order phase transition are discussed in Chapter 3. Three physics models -- the Potts model, the Go model for protein folding, and the graph model in Chapter 1 -- are simulated. Several finite size scaling models, including three functional forms to fit the energy distributions, and a capillarity model, are compared with simulations of the corresponding physics models.

description: Random key graphs form a class of random intersection graphs and are naturally induced by the random key predistribution scheme of Eschenauer and Gligor for securing wireless sensor network (WSN) communications. Random key graphs have received much interest recently, owing in part to their wide applicability in various domains including recommender systems, social networks, secure sensor networks, clustering and classification analysis, and cryptanalysis to name a few. In this paper, we study connectivity properties of random key graphs in the presence of unreliable links. Unreliability of the edges are captured by independent Bernoulli random variables, rendering edges of the graph to be on or off independently from each other. The resulting model is an intersection of a random key graph and an Erdos-Renyi graph, and is expected to be useful in capturing various real-world networks; e.g., with secure WSN applications in mind, link unreliability can be attributed to harsh environmental conditions severely impairing transmissions. We present conditions on how to scale this model's parameters so that i) the minimum node degree in the graph is at least k, and ii) the graph is k-connected, both with high probability as the number of nodes becomes large. The results are given in the form of zeroone laws with critical thresholds identified and shown to coincide for both graph properties. These findings improve the previous results by Rybarczyk on the k-connectivity of random key graphs (with reliable links), as well as the zero-one laws by Yagan on the 1-connectivity of random key graphs with unreliable links.

Calculation of the effect of random superfluid density on the temperature dependence of the penetration depth

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: Microscopic variations in composition or structure can lead to nanoscale inhomogeneity in superconducting properties such as the magnetic penetration depth, but measurements of these properties are usually made on longer length scales. We solve a generalized London equation with a non-uniform penetration depth, lambda(r), obtaining an approximate solution for the disorder-averaged Meissner effect. We find that the effective penetration depth is different from the average penetration depth and is sensitive to the details of the disorder. These results indicate the need for caution when interpreting measurements of the penetration depth and its temperature dependence in systems which may be inhomogeneous.
Mutational pathway determines whether drug gradients accelerate evolution of drug-resistant cells

description: Drug gradients are believed to play an important role in the evolution of bacteria resistant to antibiotics and tumors resistant to anti-cancer drugs. We use a statistical physics model to study the evolution of a population of malignant cells exposed to drug gradients, where drug resistance emerges via a mutational pathway involving multiple mutations. We show that a non-uniform drug distribution has the potential to accelerate the emergence of resistance when the mutational pathway involves a long sequence of mutants with increasing resistance, but if the pathway is short or crosses a fitness valley, the evolution of resistance may actually be slowed down by drug gradients. These predictions can be verified experimentally, and may help to improve strategies for combatting the emergence of resistance.

Virtue and situation : effects of situational factors on attention and emotion
Creators: name: Brooks, Ian Gregory
Publisher: name: University of British Columbia
Year: 2013

description: Many psychological studies have results that are difficult to explain in terms of the neo-Aristotelian model of virtue, vice and moral education. This thesis asks whether neo-Aristotelian moral psychology can account for empirical data on the effects that situational factors have on behaviour, specifically studies where situations affect attention and emotion. Some neo-Aristotelians argue that studies of behaviour are irrelevant to virtue theory; I disagree. John Doris’ situationist critique of virtue ethics has significant flaws, but its central point stands: neo-Aristotelian states of character as usually conceived imply predictions about behaviour that are empirically unreliable, leading to the conclusion that neo-Aristotelian moral psychology is problematic as a model of what human beings are really like. Talk of virtues and vices does not explain or predict the disproportionate effects seen in these studies. Doris argues that only local traits such as “office-party-sociability” are reliable predictors of behaviour. I respond to the situationist critique by looking for ways of supplementing neo-Aristotelian moral psychology to account for the effects of situational factors on behaviour. The main contribution of my dissertation is to show that there are interpersonal differences in behaviour which are best explained in terms of dispositions that modulate the degree to which situational factors affect attention and emotion. Contrary to situationism, the influence of these dispositions is not restricted to specific situations like office parties. These dispositions behave like neo-Aristotelian states of character. They are teachable, and they are responsive to reason. I argue that these dispositions are constituents of virtue; each virtue consists of a set of dispositions, and each virtue’s set consists in part of dispositions to pay attention in an appropriately selective manner. Dispositions to pay appropriately selective attention can account for many of the effects of situations on behaviour in a way that most neo-Aristotelians would find unobjectionable. However, I have one conclusion which may disturb some neo-Aristotelians: it may be impossible for one person to become virtuous in every respect. I suggest that virtue might require not personal perfection but appropriate interpersonal trust.

description: Biclustering, the process of simultaneously clustering the rows and columns of a data matrix, is a popular and effective tool for finding structure in a high-dimensional dataset. Many biclustering procedures appear to work well in practice, but most do not have associated consistency guarantees. To address this shortcoming, we propose a new biclustering procedure based on profile likelihood. The procedure applies to a broad range of data modalities, including binary, count, and continuous observations. We prove that the procedure recovers the true row and column classes when the dimensions of the data matrix tend to infinity, even if the functional form of the data distribution is misspecified. The procedure requires computing a combinatorial search, which can be expensive in practice. Rather than performing this search directly, we propose a new heuristic optimization procedure based on the Kernighan-Lin heuristic, which has nice computational properties and performs well in simulations. We demonstrate our procedure with applications to congressional voting records, and microarray analysis.

We use the BlackHat library in conjunction with SHERPA and a recently developed algorithm for assembling primitive amplitudes into color-dressed amplitudes. We adopt the cuts used by ATLAS in their study of multi-jet events in pp collisions at \sqrt{s} = 7 TeV. We include estimates of nonperturbative corrections and compare to ATLAS data. We store intermediate results in a framework that allows the inexpensive computation of additional results for different choices of scale or parton distributions.

The effects of litter quantity and quality on soil nutrients and litter invertebrates in two contrasting forests of southwestern China
Creators: name: Lu, Jessica Ming Chieh
Publisher: name: University of British Columbia
Year: 2013

description: Yunnan Province in southwestern China is a highly biodiverse region in the world, yet a large part of the forests are cut down every year to accommodate plantations of rubber, tea and eucalyptus. Within the small areas of protected habitats, recent observations indicate that there is a lack of regeneration of seedlings. One possible explanation for this lack of regeneration could be due to litter dynamics. We designed and carried out a short term litter decomposition experiment to test the direct effects of litter manipulations on soil nutrients and litter invertebrates in a lowland and a montane tropical forest. Our experimental design involved testing both litter quantity and litter quality. To test for the effects of litter quantity, we manipulated different depths of mixed litter, with and without periodic topping up. To test for the effects of litter quality, we compared single species of litter versus mixed litter control plots. The response of soil nutrients to these manipulations were monitored using ion exchange membranes. We show a clear difference in the available soil nutrients between the two sites, and while the litter quantity experiment had an effect on soil nutrients at the lowland site, it had no effect at the montane site. The litter quality treatments produced no overall difference in responses at either site. The response of litter invertebrates to litter manipulations was estimated using pitfall traps. We show that, litter invertebrate composition between the two forests is different. Invertebrate abundance does increase with increasing biomass at the montane site, although there seems to be a threshold of litter volume beyond which there is an effect. In the lowland site, invertebrate abundance is highest in the litter removal plots, although a general increase with litter biomass was detected. Litter species does not have an effect on either invertebrate abundance or richness at either site.

description: Sparse coding in learned dictionaries has been established as a successful approach for signal denoising, source separation and solving inverse problems in general. A dictionary learning method adapts an initial dictionary to a particular signal class by iteratively computing an approximate factorization of a training data matrix into a dictionary and a sparse coding matrix. The learned dictionary is characterized by two properties: the coherence of the dictionary to observations of the signal class, and the self-coherence of the dictionary atoms. A high coherence to the signal class enables the sparse coding of signal observations with a small approximation error, while a low self-coherence of the atoms guarantees atom recovery and a more rapid residual error decay rate for the sparse coding algorithm. The two goals of high signal coherence and low self-coherence are typically in conflict, therefore one seeks a trade-off between them, depending on the application. We present a dictionary learning method with an effective control over the self-coherence of the trained dictionary, enabling a trade-off between maximizing the sparsity of codings and approximating an equiangular tight frame.

description: We review the notions of (weak) Hermitian-Yang-Mills structure and approximate Hermitian-Yang-Mills structure for Higgs bundles. Then, we construct the Donaldson functional for Higgs bundles over compact Kähler manifolds and we present some basic properties of it. In particular, we show that its gradient flow can be written in terms of the mean curvature of the Hitchin-Simpson connection. We also study some properties of the solutions of the evolution equation associated with that functional. Next, we study the problem of the existence of approximate Hermitian-Yang-Mills structures and its relation with the algebro-geometric notion of semistability and we show that for a compact Riemann surface, the notion of approximate Hermitian-Yang-Mills structure is in fact the differential-geometric counterpart of the notion of semistability. Finally, we review the notion of admissible hermitian structure on a torsion-free Higgs sheaf and define the Donaldson functional for such an object.

description: We analytically calculate properties of a strongly coupled striped superconductor, with the charge density wave sourced by a modulated chemical potential, in the large modulation wavenumber Q limit. In the absence of a homogeneous term in the chemical potential, we show that the critical temperature scales as a negative power of Q for scaling dimensions Δ< 3/2, whereas for Δ> 3/2, there is no phase transition above a certain critical value of Q. The condensate is found to scale as a positive power of Q such that the gap is proportional to Q. We discuss how these results change if a homogeneous term is added to the chemical potential. We compare our analytic results with numerical calculations whenever the latter are available and find good agreement.

On the resonant Lane-Emden problem for the p-Laplacian

description: We study the positive solutions of the Lane-Emden equation $-Δ_{p}u=λ_{p}|u|^{q-2}u$ in $Ω$ with homogeneous Dirichlet boundary conditions, where $Ω\subset\mathbb{R}^{N}$ is a bounded and smooth domain, $N\geq2,$ $λ_{p}$ is the first eigenvalue of the $p$-Laplacian operator $Δ_{p}$ and $q$ is close to $p>1.$ We prove that any family of positive solutions of this problem converges in $C^{1}(\barΩ)$ to the function $θ_{p}e_{p}$ when $q\rightarrow p,$ where $e_{p}$ is the positive and $L^{\infty}$-normalized first eigenfunction of the $p$-Laplacian and $θ_{p}:=\exp(|e_{p}|_{L^{p}(Ω)}^{-p}\int_Ωe_{p}% ^{p}|\ln e_{p}|dx).$ A consequence of this result is that the best constant of the immersion $W_{0}^{1,p}(Ω)\hookrightarrow L^{q}(Ω)$ is differentiable at $q=p.$ Previous results on the asymptotic behavior (as $q\rightarrow p$) of the positive solutions of the non-resonant Lane-Emden problem (i.e. with $λ_{p}$ replaced by a positive $λ\neqλ_{p}$) are also generalized to the space $C^{1}% (\barΩ)$ and to arbitrary families of these solutions. Moreover, if $u_{λ,q}$ denotes a solution of the non-resonant problem for an arbitrarily fixed $λ>0,$ we show how to obtain the first eigenpair of the $p$-Laplacian as the limit in $C^{1}(\barΩ),$ when $q\rightarrow p$, of a suitable scaling of the pair $(λ,u_{λ,q}).$ For computational purposes the advantage of this approach is that $λ$ does not need to be close to $λ_{p}.$ Finally, an explicit estimate involving $L^{\infty}$ and $L^{1}$ norms of $u_{λ,q}$ is also deduced using set level techniques.
description: The paper was improved and completely reformulated. The main result now is valid for any family of positive solutions in the super-linear case (not necessarily ground state)

description: We present an algorithm to generate positive braids of a given length as words in Artin generators with a uniform probability. The complexity of this algorithm is polynomial in the number of strands and in the length of the generated braids. As a byproduct, we describe a finite state automaton accepting the language of lexicographically minimal representatives of positive braids that has the minimal possible number of states, and we prove that its number of states is exponential in the number of strands.
The dynamics of inner dead-zone boundaries in protoplanetary disks

description: In protoplanetary disks, the inner radial boundary between the MRI turbulent (`active') and MRI quiescent (`dead') zones plays an important role in models of the disk evolution and in some planet formation scenarios. In reality, this boundary is not well-defined: thermal heating from the star in a passive disk yields a transition radius close to the star (<0.1 au), whereas if the disk is already MRI active, it can self-consistently maintain the requisite temperatures out to a transition radius of roughly 1 au. Moreover, the interface may not be static; it may be highly fluctuating or else unstable. In this paper, we study a reduced model of the dynamics of the active/dead zone interface that mimics several important aspects of a real disk system. We find that MRI-transition fronts propagate inward (a `dead front' suppressing the MRI) if they are initially at the larger transition radius, or propagate outward (an `active front' igniting the MRI) if starting from the smaller transition radius. In both cases, the front stalls at a well-defined intermediate radius, where it remains in a quasi-static equilibrium. We propose that it is this new, intermediate stalling radius that functions as the true boundary between the active and dead zones in protoplanetary disks. These dynamics are likely implicated in observations of variable accretion, such as FU Ori outbursts, as well as in those planet formation theories that require the accumulation of solid material at the dead/active interface.

Extra U(1) as natural source of a monochromatic gamma ray line

description: Extensions of the Standard Model with an extra U'(1) abelian group generically generate terms coming from loops of heavy fermions, leading to three gauge boson couplings, in particular Z'Z gamma. We show that WMAP data constrains the gauge coupling of the group g_D to values comparable with the electro-weak ones, rather independently of the mass of Z'. Moreover, the model predicts a monochromatic gamma-ray line which can fit a 130 GeV signal at the FERMI telescope for natural values of the Chern-Simons terms and a dark matter mass around 144.5 GeV.

Canadian producer and citizen perspectives on farm animal welfare : identifying shared and differing values
Creators: name: Spooner, Jeffrey Michael
Publisher: name: University of British Columbia
Year: 2013

description: While interest in the “proper” care of food animals dates to early Greece, 20th century cultural developments in the West brought about an explosion of policies and programs intended to ensure suitable care and handling practices for food animals. “Animal welfare”, however, is a complex term reflecting a wide range of elements. Hence, animal care policies often lead to confusion and disagreements. Given that animal welfare preferences tend to reflect fundamental values and attitudes, agreement on animal care practices are most apt to ensue if such practices reflect shared values and attitudes among vested stakeholders. In an effort to contribute to the development of broadly acceptable policies and practices, in-depth interviews were conducted with beef cattle producers (n=23), pig producers (n=20), and the public (n=24) in the quest for shared or overlapping values regarding farm animal welfare. Areas of agreement include: (i) the importance of humane handling plus good health and biological functioning, especially emphasized by producers; (ii) that consumers have considerable power to dictate preferred care practices and that producers are constrained by economic pressures in competitive markets; and (iii) that citizens lack sufficient understanding of contemporary production methods. Commensurate policy recommendations intended to build on areas of agreement include: (i) the promotion of shared terminology emphasizing animal care; (ii) incorporating elements of natural living into intensive production systems; (iii) promoting joint stakeholder pilot projects to test welfare-oriented production methods or prevent catastrophic animal care failures; (iv) facilitating a trustworthy system of product labelling; (v) encouraging transparent producer or industry driven, welfare-related initiatives; and (vi) encouraging stakeholders to use publicly trusted educational resources instead of marketing-oriented representations of animal care practices. Future research recommendations include: (i) more qualitative and empirical studies of consumers’ welfare-related purchasing practices; and (ii) exploring producer welfare concerns in the broader context of production or management priorities or values. Contributions to existing knowledge include the identification of shared and differing values among Canadian stakeholders, challenges to blanket welfare criticisms about commercial production, plausible paradigmatic differences between producers and citizens, and the potential impact of differing production systems on the welfare-related views of producers.
