CONTINUOUS RELAXATION FOR COMBINATORIAL PROBLEMS - A STUDY OF CONVEX AND INVEX PROGRAMS
Creators: name: Barik, Adarsh
Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Machine learning not elsewhere classified

description: In this thesis, we study optimization problems which have a combinatorial aspect to them. Search space for such problems quickly grows large - exponentially - with respect to the problem dimension. Thus, exhaustive search becomes intractable and we need good relaxations to solve combinatorial problems efficiently. Another challenge arises due to the high dimensionality of such problems and lack of large number of samples. Our aim is to come up with innovative approaches that solve the problem in polynomial time and sample complexity. We discuss three combinatorial optimization problems and provide continuous relaxations for them. Our continuous relaxations involve both convex and nonconvex (invex) relaxations. Furthermore, we provide efficient first order algorithms to solve a general class of invex problems with provable convergence rate guarantees. The three combinatorial problems we study in this work are – learning the directed structure of a Bayesian network using blackbox data, fair sparse regression on a biased dataset where bias depends upon a hidden binary attribute and mixed linear regression. We propose convex relaxation for the first problem, while the other two are solved using invex relaxation. On the first problem, we come up with a novel notion of low rank representation of conditional probability tables for a Bayesian network and connect it to Fourier transformation of real valued set functions to recover the exact structure of the Bayesian networks. For the second problem, we propose a novel invex relaxation for the combinatorial version of sparse linear regression with fairness. For the final problem, we again use invex relaxation to learn a mixture of sparse linear regression models. We formally show correctness of our proposed methods and provide provable theoretical guarantees for efficient computational and sample complexity. We also develop efficient first order algorithms to solve invex problems. We provide convergence rate analysis for our proposed methods. Furthermore, we also discuss possible future research directions and the problems we want to tackle in future.
Labyrinthulomycetes diversity meta-analysis
Creators: name: Pan, Jingwen
Publisher: name: University of British Columbia
Year: 2016

description: Labyrinthulomycetes are a group of ubiquitous stramenopiles that inhabit a wide range of habitats and play important ecological roles as nutrient recyclers and sometimes disease causing agents. Even though they have had a long history of being studied, their diversity has not yet been fully explored. The lack of a comprehensive reference database with up-to-date phylogeny also hinders any pursuits in understanding the ecological distribution of this group. This study was designed with the purpose of constructing a curated reference database and a phylogenetic tree based on existing 18S rDNA data, and then using this database to uncover any hidden diversity and novelty among Labyrinthulomycetes and provide a reference guidance for future identification. Using the newly-created reference database, I also analyzed high-throughput environmental sequencing data from two databases. My results reveal extensive diversity within the Labyrinthulomycetes, and recover many previously unknown environmental sequences, greatly expanding our knowledge of the ecological distribution of this group. The high-throughput environmental sequencing data analysis also shows some of the newly identified environmental clades to be particularly abundant in the ocean. The phylogenetic framework I have provided in this study, together with the metadata I have compiled, will serve as a useful tool for future ecological and evolutionary studies of this widespread lineage.

description: Electronic transport properties through some model quantum systems are re-visited. A simple tight-binding framework is given to describe the systems where all numerical calculations are made using the Green's function formalism. First, we demonstrate electronic transport in four different polycyclic hydrocarbon molecules, namely, benzene, napthalene, anthracene and tetracene. It is observed that electron conduction through these molecular wires is highly sensitive to molecule-to-electrode coupling strength and quantum interference of electronic waves passing through different branches of the molecular ring. Our investigations predict that to design a molecular electronic device, in addition to the molecule itself, both the molecular coupling and molecule-to-electrode interface geometry are highly important. Next, we make an in-depth study to design classical logic gates with the help of simple mesoscopic rings, based on the concept of Aharonov-Bohm effect. A single mesoscopic ring or two such rings are used to establish the logical operations where the key controlling parameter is the magnetic flux threaded by the ring. The analysis might be helpful in fabricating meso-scale or nano-scale logic gates. Finally, we address multi-terminal quantum transport through a single benzene molecule using Landauer-Büttiker formalism. Quite interestingly we see that a three-terminal benzene molecule can be operated as an electronic transistor and this phenomenon is justified through current-voltage characteristics. All these essential features of electron transport may provide a basic theoretical framework to examine electron conduction through any multi-terminal quantum system.

description: We calculate the masses of the resonances D_{s0}^*(2317) and D_{s1}(2460) as well as their bottom partners as bound states of a kaon and a D^*- and B^*-meson, respectively, in unitarized chiral perturbation theory at next-to-leading order. After fixing the parameters in the D_{s0}^*(2317) channel, the calculated mass for the D_{s1}(2460) is found in excellent agreement with experiment. The masses for the analogous states with a bottom quark are predicted to be M_{B^*_{s0}}=(5696\pm 40) MeV and M_{B_{s1}}=(5742\pm 40) MeV in reasonable agreement with previous analyses. In particular, we predict M_{B_{s1}}-M_{B_{s0}^*}=46\pm 1 MeV. We also explore the dependence of the states on the pion and kaon masses. We argue that the kaon mass dependence of a kaonic bound state should be almost linear with slope about unity. Such a dependence is specific to the assumed molecular nature of the states. We suggest to extract the kaon mass dependence of these states from lattice QCD calculations.

Rhetorical emergence and the economy : the Sante Fe Institute Artificial Stock Market, complexity economics, and the rhetorical dimensions of economic activity.
Creators: name: Eldredge, Blaine Thomas
Publisher: name: University of British Columbia
Year: 2016

description: Drawing on work in digital and algorithmic rhetoric, I analyze the organization of space and time in complexity models. I argue that the success of complexity economic models is a consequence of their ability to reflect the rhetorical situation of the marketplace: they represent time as a series of causal interactions and space as a consequence of coordinated interaction. Complexity economics investigates the inclination of markets to behave as complex systems: self-organizing, emergent, and non-linear. The 1999 Artificial Stock Market designed by Sante Fe Institute theorists Blake LeBaron, William Brian Arthur, and Richard Palmer is perhaps the fundamental expression of a complex marketplace. It was among the first models to accurately predict market downturns, a success that followed as a consequence of its construction. In ordinary market models, traders are driven by profit maximization and a simple recursive strategy: they remember their mistakes, and respond to analogous market situations with new information in a linear, causal process. In their model, LeBaron, Arthur, and Palmer created a series of overlapping causal processes in which the market could operate as a persuasive agent. In complexity economics, the market is itself an interlocutive agent, thereby permitting nonlinear, bidirectional causality. These causal modes have spatial and temporal corollaries. The unique compositions of complex economies is rhetorical. Their complex causal processes reflect a discursive marketplace in which space and time to emerge as relational properties.

description: We study the time-dependent transmission of entanglement entropy through an out-of-equilibrium model interacting device in a quantum transport set-up. The dynamics is performed via the Kadanoff-Baym equations within many-body perturbation theory. The double occupancy $< \hat{n}_{R \uparrow} \hat{n}_{R \downarrow} >$, needed to determine the entanglement entropy, is obtained from the equations of motion of the single-particle Green's function. A remarkable result of our calculations is that $< \hat{n}_{R \uparrow} \hat{n}_{R \downarrow} >$ can become negative, thus not permitting to evaluate the entanglement entropy. This is a shortcoming of approximate, and yet conserving, many-body self-energies. Among the tested perturbation schemes, the $T$-matrix approximation stands out for two reasons: it compares well to exact results in the low density regime and it always provides a non-negative $< \hat{n}_{R \uparrow} \hat{n}_{R \downarrow} >$. For the second part of this statement, we give an analytical proof. Finally, the transmission of entanglement across the device is diminished by interactions but can be amplified by a current flowing through the system.

description: The sensitivity of the stellar moment of inertia to the neutron-star matter equation of state is examined using accurately-calibrated relativistic mean-field models. We probe this sensitivity by tuning both the density dependence of the symmetry energy and the high density component of the equation of state, properties that are at present poorly constrained by existing laboratory data. Particularly attractive is the study of the fraction of the moment of inertia contained in the solid crust. Analytic treatments of the crustal moment of inertia reveal a high sensitivity to the transition pressure at the core-crust interface. This may suggest the existence of a strong correlation between the density dependence of the symmetry energy and the crustal moment of inertia. However, no correlation was found. We conclude that constraining the density dependence of the symmetry energy - through, for example, the measurement of the neutron skin thickness in 208Pb - will place no significant bound on either the transition pressure or the crustal moment of inertia.

Design and evaluation of trajectory-based tasks in a thin-seam perspective-corrected cubic display
Creators: name: Tang, Yichen
Publisher: name: University of British Columbia
Year: 2016

description: This thesis describes the design and evaluation of wire-tracing task in pCubee, an improved version of hand-held perspective-corrected display that allows the user to observe and interact with 3D content visualized inside the cubic system. In order to overcome visual discontinuity issues identified from previous works, we redesigned pCubee system using OLED panels and FPGA-based display controller to achieve reduced seam size and compact form-factor. We investigated user performance with the new system using a trajectory-based wire-tracing task where users were asked to move a ring along wires. Experiments were conducted to evaluate the impact of ring radius, wire length and curvature. Analysis of results revealed that a linear model similar to the steering law for 2D tunnel task applies to 3D trajectory-based task in pCubee as well, exhibiting an increase of task completion time when smaller ring or longer wire is used. Our study complemented the theory that 3D interaction in virtual reality system follows existing principle for 2D tasks, and also identified a potential method to evaluate interaction designs for geometric displays. This work could help motivate future development of pCubee and guide interaction design for similar systems.

description: Protons and helium nuclei are the most abundant components of the cosmic radiation. Precise measurements of their fluxes are needed to understand the acceleration and subsequent propagation of cosmic rays in the Galaxy. We report precision measurements of the proton and helium spectra in the rigidity range 1 GV-1.2 TV performed by the satellite-borne experiment PAMELA. We find that the spectral shapes of these two species are different and cannot be well described by a single power law. These data challenge the current paradigm of cosmic-ray acceleration in supernova remnants followed by diffusive propagation in the Galaxy. More complex processes of acceleration and propagation of cosmic rays are required to explain the spectral structures observed in our data.

Children of multiple sclerosis : impact of chronic disease in parents on child and adolescnet development
Creators: name: Razaz, Neda
Publisher: name: University of British Columbia
Year: 2016

description: Approximately 10% of children live in households where a parent has a chronic illness and many children are exposed to a parent coping with a potentially disabling chronic condition, such as multiple sclerosis (MS). However, few methodologically rigorous studies have evaluated the impact of parental MS on child development. The purpose of this thesis was to fill this knowledge gap by studying the association between parental MS and child and adolescent development. The studies in this dissertation were based on population-based health databases from Manitoba and British Columbia. The cohorts followed in these population-based studies included all individuals with MS who had a child with a completed Early Development Instrument (EDI) school readiness assessment, and matched parent-child dyads of unaffected parents. Parents with MS were identified using a validated algorithm, as those with ≥3 records related to MS in hospital admission, physician visit or prescription claims. Mental and physical morbidity in parents and children were also identified through a combination of hospital, physician and drug claims. In Manitoba, children in kindergarten with an MS parent were similar to matched children of unaffected parents on all developmental domains as assessed by the EDI. However, in the larger population-based cohort from British Columbia, children of mothers with MS had lower rates of vulnerability on the social competence domain (odds ratio 0.62, 95% confidence interval [CI] 0.44-0.87). Overall, mental health morbidity, such as anxiety and depression, was significantly more common among MS parents compared with MS-unaffected parents. Additionally, such parental mental health morbidity mediated the association between maternal MS and mood and/or anxiety disorders in children. Incidence rates of psychiatric disorders were significantly higher in children and adolescents with an MS parent who were exposed to parental MS since birth, compared with children and adolescents of MS-unaffected parents (hazard ratio 1.37, 95% CI 1.05-1.78). In summary, the presence of parental MS was not independently associated with adverse developmental health in kindergarten-aged children. However, MS was associated with substantially higher levels of mental health morbidity in parents and such morbidity was associated with adverse child and adolescent psychiatric morbidity.

This is explained by noting that the photo-induced metallic state of 1T-TaS2 is one in which the Mott gap is melted but the lattice retains its low-temperature symmetry, a regime only accessible by photo-doping.

description: Modelling compositional meaning for sentences using empirical distributional methods has been a challenge for computational linguists. We implement the abstract categorical model of Coecke et al. (arXiv:1003.4394v1 [cs.CL]) using data from the BNC and evaluate it. The implementation is based on unsupervised learning of matrices for relational words and applying them to the vectors of their arguments. The evaluation is based on the word disambiguation task developed by Mitchell and Lapata (2008) for intransitive sentences, and on a similar new experiment designed for transitive sentences. Our model matches the results of its competitors in the first experiment, and betters them in the second. The general improvement in results with increase in syntactic complexity showcases the compositional power of our model.

description: The electronic structure of nanographene in pristine and fluorinated activated carbon fibers (ACFs) have been investigated with near-edge x-ray absorption fine structure (NEXAFS) and compared with magnetic properties we reported on previously. In pristine ACFs in which magnetic properties are governed by non-bonding edge states of the π-electron, a pre-peak assigned to the edge state was observed below the conduction electron π* peak close to the Fermi level in NEXAFS. Via the fluorination of the ACFs, an extra peak, which was assigned to the σ-dangling bond state, was observed between the pre-peak of the edge state and the π* peak in the NEXAFS profile. The intensities of the extra peak correlate closely with the spin concentration created upon fluorination. The combination of the NEXAFS and magnetic measurement results confirms the coexistence of the magnetic edge states of π-electrons and dangling bond states of σ-electrons on fluorinated nanographene sheets.

description: We propose an idea to investigate persistent current in individual arms of a multi-arm mesoscopic ring. Following a brief description of persistent current in a traditional Aharonov-Bohm (AB) ring, we examine the behavior of persistent currents in separate arms of a three-arm mesoscopic ring. Our analysis may be helpful in studying magnetic response of any complicated quantum network.

Using smallness of some derivatives of inflow function, external force and initial velocity of the flow, but with no smallness restrictions on the inflow, initial velocity neither force, we prove existence of solutions in $W^{2,1}_2.$

To illustrate the results, we provide several examples and discuss a quantum version of the well known Ramsey model of economics.

description: Peterson et al. [2009] intend to determine the NOx production of sprites and blue jets from laboratory experiments. Sprite discharges are known to be physically similar to streamer discharges at standard temperature and pressure. However, streamer experiments that simulate geophysical discharges require voltage pulses of one polarity, in contrast to the oscillating voltages of Peterson et al. Furthermore, Peterson et al. make errors in their comparison of current densities, sprite volumes and gas densities. Finally, there is a calculation error of 6 orders of magnitude in an important result.

Atomic population distribution in the output ports of cold-atom interferometers with optical splitting and recombination

Year: 2010
Subjects: subject: Atomic Physics (physics.atom-ph)
subject: FOS: Physical sciences

description: Cold-atom interferometers with optical splitting and recombination use off-resonant laser beams to split a cloud of Bose-Einstein condensate (BEC) into two clouds that travel along different paths and are then recombined again using optical beams. After the recombination, the BEC in general populates both the cloud at rest and the moving clouds. Measuring relative number of atoms in each of these clouds yields information about the relative phase shift accumulated by the atoms in the two moving clouds during the interferometric cycle. We derive the expression for the probability of finding any given number of atoms in each of the clouds, discuss features of the probability density distribution, analyze its dependence on the relative accumulated phase shift as a function of the strength of the interatomic interactions, and compare our results with experiment.

Dynamic process simulation of zinc electrowinning
Creators: name: Mahon, Michael John
Publisher: name: University of British Columbia
Year: 2016

description: Zinc electrowinning is the final aqueous processing step in the production of metallic zinc. It is a complex process that is difficult to control and monitor. This thesis seeks to develop a time transient process simulation of zinc electrowinning to aid in controlling and monitoring. Based on reported models of zinc electrowinning, and other electrowinning processes, a dynamic simulation of a zinc electrowinning cell capable of representing time-based effects was developed. The new model incorporates more sophisticated estimations of electrolyte activity using Pitzer parameters. Further, recently determined empirical relations for solution conductivity, density and viscosity were included. The effect of gas evolution on the conductivity of solution was also included. First, the simulation was validated using a reported data set, and the kinetic constants of the primary cathodic reactions were determined using a simplex optimization algorithm. A model of a counter-flow cooling tower was also developed in order to simulate a full cell house. The simulation was then successfully validated against data collected from three industrial cell houses in Canada. Once validated, the simulation was used to investigate its possible applications. The benefits of optimizing a single electrowinning cell in comparison to optimizing the cell house was examined. Due to the inability to directly control both the acid and zinc concentrations in the electrowinning cell without major process changes, it was established that the optimal single cell conditions favoured zinc concentrations of approximately 70 g L‐¹, while the cell house optimization favoured lower zinc concentrations by comparison (approximately 50 g L‐¹). The simulation was used to track the consumption of manganese ions in the cell house when using variable concentrations of manganese in the purified electrolyte fed to the cell house. The experimental rates reported for Mn consumption overestimated the Mn consumption in a cell house. The simulation was also used to investigate process control strategies. With the use of a basic process control scheme, the production could increase by 4 % and decrease the variability in the spent electrolyte concentration.

description: We consider time-fractional parabolic equations with a Caputo time derivative of order α ∈ (0, 1). For such equations, we give an elementary proof of the weak maximum principle under no assumptions on the sign of the reaction coefficient. This proof is also extended for weak solutions, as well as for various types of boundary conditions and variable-coefficient variable-order multiterm time-fractional parabolic equations

description: This study concerns the fast and accurate solution of multilevel non-LTE radiation transfer problems. We propose and evaluate an alternative iterative scheme to the classical MALI method. Our study is indeed based on the application of Broyden's method for the solution of nonlinear systems of equations. Comparative tests, in 1D plane-parallel geometry, between the popular MALI method and our alternative method are discussed. The Broyden method is typically 4.5 times faster than MALI. It makes it also fairly competitive with Gauss-Seidel and Successive Over-Relaxation methods developed after MALI.

description: We describe which knots can be obtained as cycles in the canonical book representation of K_n, the complete graph on n vertices. We show that the canonical book representation of K_n contains a Hamiltonian cycle that is a composite knot if and only if n>11 and we show that when p and q are relatively prime, the (p,q) torus knot is a Hamiltonian cycle in the canonical book representation of K_{2p+q}. Finally, we list the number and type of all non-trivial knots that occur as cycles in the canonical book representation of K_n for n<12. We conjecture that the canonical book representation of K_n attains the least possible number of knotted cycles for any embedding of K_n.
