Thue equations
Creators: name: Ghadermarzi, Amir
Publisher: name: University of British Columbia
Year: 2014

description: In this dissertation, we are mainly interested in effective methods to solve parametrized Thue equations. After briefly talking about the different effective methods, two parametrized families of cubic Thue equations are completely solved by using Pad é approximation and linear forms in logarithms. The Thue inequality ∣x³ + pxy² + qy³ ∣≤ k, is studied by using Bombieri's method. We find all solutions under some conditions on k, p and q. As an application of Thue equations, we find the integral points on the Mordell curves Y² = X³ + k for all nonzero integers k with ∣k∣ ≤ 10⁷ . Our approach uses a classical connection between these equations and cubic Thue equations.

Side-entrainment in a jet embedded in a sidewind

description: Numerical simulations of HH jets never show side-entrainment of environmental material into the jet beam. This is because the bow shock associated with the jet head pushes the surrounding environment into a dense shell, which is never in direct contact with the sides of the jet beam. We present 3D simulations in which a side-streaming motion (representing the motion of the outflow source through the surrounding medium) pushes the post-bow shock shell into direct contact with the jet beam. This is a possible mechanism for modelling well collimated "molecular jets" as an atomic/ionic flow which entrains molecules initially present only in the surrounding environment.

Towards nudging active travel : behavioral interventions using mobile technology
Creators: name: Baird, Timothy David
Publisher: name: University of British Columbia
Year: 2014

description: Advances in behavioural economics have begun to provide a new toolkit of theories, models, and empirical methods for designing and evaluating policy. While many of these techniques are highly relevant to behavioral problems that planners encounter when consulting the public, crafting policy and regulations, and promoting sustainable patterns of behavior, this approach has received only limited attention in the planning and transportation literature. I review this literature and present a framework for generating, implementing, and testing the results of different interventions designed to affect users’ travel behavior by delivering behavioral feedback via an activity-tracking smartphone application. The results of this promotional strategy are tested in two pilot projects among university students and “Bike to Work Week” participants in British Columbia and Minnesota. I also present further tools for conducting such experiments and additional experimental designs relevant to testing these hypotheses. Implications for program evaluation, planning practice, and transportation research are discussed.

description: We show how to find a minimum weight loop cutset in a Bayesian network with high probability. Finding such a loop cutset is the first step in the method of conditioning for inference. Our randomized algorithm for finding a loop cutset outputs a minimum loop cutset after O(c 6^k kn) steps with probability at least 1 - (1 - 1/(6^k))^c6^k, where c > 1 is a constant specified by the user, k is the minimal size of a minimum weight loop cutset, and n is the number of vertices. We also show empirically that a variant of this algorithm often finds a loop cutset that is closer to the minimum weight loop cutset than the ones found by the best deterministic algorithms known.

description: In this article, we will present the first experimental observation of nanojets formed by heating PbO-coated Pb clusters, which has been predicted theoretically by M. Moseler and U Landman. During the heating, the hot liquid ejects through the broken orifice into vacuum, and forms a condensed trail in the tadpole shape as shown in the TEM micrographs. The temperature-variable Raman spectra indicates that the nanojet formation is closely related to the heating temperature and thus essentially to the internal pressure in the coated clusters. The pressure inside the shell, which rises from the inner core's melting and its confined volume expansion and then drops after the final explosion, dominates the whole nanojetting process.
Examining Teachers’ Causal Attribution of Challenging Behaviour in Primary Classrooms, West Bengal, India.

subject: Teacher education and professional development of educators

description: This study investigates Indian teachers’ causal attributions of students’ challenging behaviour and their choice of strategies to address the behaviour. Two interconnected studies were conducted to achieve the objective of the project. The findings suggested that teachers attributed student-related and family-related factors as the main causes of students’ behaviour and suggested using proactive strategies to address challenging behaviours. Furthermore, it was found that teachers’ demographics were significant predictors of their causal attributions and suggested strategies. The study has implications for researchers, educational practitioners, and policymakers.
Remarkable paramagnetic features of Fermi-Dirac plasmas

Year: 2011
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: In this paper by using the relativistic magnetic susceptibility of a Fermi-Dirac (relativistically degenerate) plasma, quantum magnetohydrodynamics (QMHD) model is used to investigate the propagation of spin-induced (SI) magnetosonic nonlinear excitations in a normally and relativistically degenerate dense electron-ion plasma in the presence of the spin magnetization effect. Based on the conventional pseudopotential method the matching criterion for the evolution of SI solitary structures is evaluated. It is found that, the plasma mass density and strength of the magnetic field have significant effects on excitation and evolution of magnetosonic nonlinear structures in Fermi-Dirac plasmas. Only rarefactive SI magnetosonic solitary structures are found to excite in such plasmas. Furthermore, fundamental differences are shown to exist in magnetosonic soliton dynamics in the two distinct plasma degeneracy regimes, which is due to interplay between the negative spin paramagnetism pressure-like and positive relativistic degeneracy pressure of electrons. Current investigation can help better understand the electron spin effects on nonlinear wave propagations in strongly magnetized dense astrophysical objects such as white dwarfs and pulsar magnetospheres.

description: Synchronous oscillatory dynamics is frequently observed in the human brain. We analyze the fine temporal structure of phase-locking in a realistic network model and match it with the experimental data from parkinsonian patients. We show that the experimentally observed intermittent synchrony can be generated just by moderately increased coupling strength in the basal ganglia circuits due to the lack of dopamine. Comparison of the experimental and modeling data suggest that brain activity in Parkinson's disease resides in the large boundary region between synchronized and nonsynchronized dynamics. Being on the edge of synchrony may allow for easy formation of transient neuronal assemblies.

description: Shading protractor, as developed by Edward Mazria, recreated as an interactive graph in GeoGebra.

To use the protractor, one first needs to create a solar path chart for a given location, for example using the online tool available at http://solardat.uoregon.edu/SunChartProgram.html. This solar path chart has to be inserted as a background image in the shading protractor file, and the upper left corner ULC and the center P (labeled as 0 degrees) aligned with the solar path chart.

The protractor serves to illustrate shading masks for an overhang with side fins for a window with given orientation. Their defining points can be moved around freely in GeoGebra to observe how the shading mask changes accordingly.

description: We develop a theoretical description of non-adiabatic Josephson dynamics in superconducting junctions containing low energy quasiparticles. Within this approach we investigate the effects of midgap states in junctions of unconventional d-wave superconductors. We identify a reentrance effect in the transition between thermal activation and macroscopic quantum tunneling, and connect this phenomenon to the experimental observations in Phys. Rev. Lett. 94, 087003 (2005). It is also shown that nonlinear Josephson dynamics can be defined by resonant interaction with midgap states reminiscent to nonlinear optical phenomena in media of two-level atoms.

description: We present the results of a simultaneous monitoring, lasting more than 2 years, of the optical and near-infrared photometric and polarimetric activity of the variable protostar PV Cep. During the monitoring period, an outburst has occurred in all the photometric bands, whose declining phase ($Δ$J $\approx$ 3 mag) lasted about 120 days. A time lag of $\sim$ 30 days between optical and infrared light curves has been measured and interpreted in the framework of an accretion event. This latter is directly recognizable in the significant variations of the near-infrared colors, that appear bluer in the outburst phase, when the star dominates the emission, and redder in declining phase, when the disk emission prevails. All the observational data have been combined to derive a coherent picture of the complex morphology of the whole PV Cep system, that, in addition to the star and the accretion disk, is composed also by a variable biconical nebula. In particular, the mutual interaction between all these components is the cause of the high value of the polarization ($\approx$ 20%) and of its fluctuations. The observational data concur to indicate that PV Cep is not a genuine EXor star, but rather a more complex object; moreover the case of PV Cep leads to argue about the classification of other recently discovered young sources in outburst, that have been considered, maybe over-simplifying, as EXor.

Statistical Analysis of an AGN sample with Simultaneous UV and X-ray Observations with Swift

description: I report on the statistical analysis of a sample of about 100 AGN with simultaneous UV and X-ray observations with Swift. I found clear correlations between the X-ray spectral slope alpha-X, the UV slope alpha-UV, and the optical-to-x-ray spectral slope alpha-ox with the Eddington ratio L/Ledd. I also report on the bolometric corrections for L(0.2-2.0 keV) and L(5100A). A major aspect of the statistical analysis is multi-variate analysis statistical tools such as the Principal Component Analysis (PCA) and cluster analysis. This analysis shows that the main driver of the AGN properties in this sample is the Eddington ratio L/Ledd. Although separating Seyfert 1s into NLS1s and BLS1s is a good classification, with the 2000 km/s cutoff line it is still arbitrary. A better classification scheme may be to separate AGN into low and highL/Ledd AGN as suggested from the cluster analysis.

Identification of synthetic cytotoxic interactions to improve the efficacy of DNA damaging therapeutic agents
Creators: name: Moshgabadi, Noushin
Publisher: name: University of British Columbia
Year: 2014

description: Cancer therapies ideally selectively kill tumour cells and have little effect on normal cells. However, many current therapies are toxic to both tumour and normal cells. Differential killing can be achieved by exploiting the differences between tumour cells and normal cells. Tumour specific somatic mutations can be leveraged to affect selective killing by targeting secondary proteins required for the viability of mutant cancer cells. This rationale is called synthetic lethality (SL). Genome instability (GIN) genes, which are frequently mutated in tumours, are good candidates for finding SL interactions in combination with DNA repair enzyme inhibitors. If a somatically mutated GIN gene is involved in a DNA repair pathway, then inhibiting a second, parallel DNA repair pathway enzyme might trigger SL due to an inability to repair endogenous DNA damage. The combination of a GIN mutation and a DNA repair enzyme inhibitor would not be expected to result in SL in all cases. However, it may be possible that the combination of a GIN mutation and inhibition of a DNA repair enzyme could sensitize cells to low doses of a DNA damaging agent (DDA). We termed this phenomenon “synthetic cytotoxicity” (SC). The aim of my research was to discover and characterize SC relationships between GIN mutations found in tumours and loss of function of DNA repair enzymes, using Saccharomyces cerevisiae as a model experimental organism. I tested a matrix of 27 GIN mutations, three DNA repair enzyme mutations, and six different DDAs to test single and double mutants in the presence and absence of low concentrations of DDAs and discovered 6 SL interactions, 21 SC interactions, and surprisingly 19 cases of phenotypic suppression (PS). I also characterized the SC interaction between tpp1⊿ and mre11⊿ (homologous recombination defective) in response to bleomycin and revealed a crucial role for Tpp1 in the non homologous endjoining DNA repair pathway. I propose a model in which the deletion of both Mre11 and Tpp1 inhibits the resection of bleomycin-induced double strand DNA breaks, resulting in unrepaired DNA damage and synthetic cytotoxicity.

description: We show that spherical truncations of the 1/r interactions in models for water and acetonitrile yield very accurate results in bulk simulations for all site-site pair correlation functions as well as dipole-dipole correlation functions. This good performance in bulk simulations contrasts with the generally poor results found with the use of such truncations in nonuniform molecular systems. We argue that Local Molecular Field (LMF) theory provides a general theoretical framework that gives the necessary corrections to simple truncations in most nonuniform environments and explains the accuracy of spherical truncations in uniform environments by showing that these corrections are very small. LMF theory is derived from the exact Yvon-Born-Green (YBG) hierarchy by making physically-motivated and well-founded approximations. New and technically interesting derivations of both the YBG hierarchy and LMF theory for a variety of site-site molecular models are presented in appendices. The main paper focuses on understanding the accuracy of these spherical truncations in uniform systems both phenomenologically and quantitatively using LMF theory.

OBDD-based Universal Planning for Synchronized Agents in Non-Deterministic Domains

Year: 2011
Subjects: subject: Artificial Intelligence (cs.AI)

description: Recently model checking representation and search techniques were shown to be efficiently applicable to planning, in particular to non-deterministic planning. Such planning approaches use Ordered Binary Decision Diagrams (OBDDs) to encode a planning domain as a non-deterministic finite automaton and then apply fast algorithms from model checking to search for a solution. OBDDs can effectively scale and can provide universal plans for complex planning domains. We are particularly interested in addressing the complexities arising in non-deterministic, multi-agent domains. In this article, we present UMOP, a new universal OBDD-based planning framework for non-deterministic, multi-agent domains. We introduce a new planning domain description language, NADL, to specify non-deterministic, multi-agent domains. The language contributes the explicit definition of controllable agents and uncontrollable environment agents. We describe the syntax and semantics of NADL and show how to build an efficient OBDD-based representation of an NADL description. The UMOP planning system uses NADL and different OBDD-based universal planning algorithms. It includes the previously developed strong and strong cyclic planning algorithms. In addition, we introduce our new optimistic planning algorithm that relaxes optimality guarantees and generates plausible universal plans in some domains where no strong nor strong cyclic solution exists. We present empirical results applying UMOP to domains ranging from deterministic and single-agent with no environment actions to non-deterministic and multi-agent with complex environment actions. UMOP is shown to be a rich and efficient planning system.

The parent compound Ba3Mn2O8 is a dimerized, quasi-two-dimensional geometrically frustrated quantum disordered antiferromagnet. We substitute this compound with non-magnetic vanadium for the S = 1 manganese atoms, Ba3(Mn1-xVx)2O8, and find that the singlet-triplet excitations which dominate the spectrum of the parent compound persist for the full range of substitution examined, x = 0.02 to 0.3. We also observe additional low-energy magnetic fluctuations which are enhanced at the greatest substitution values. These excitations may be a precursor to a low-temperature random singlet phase which may exist in Ba3(Mn1-xVx)2O8

description: This paper reviews the connections between Graphplan's planning-graph and the dynamic constraint satisfaction problem and motivates the need for adapting CSP search techniques to the Graphplan algorithm. It then describes how explanation based learning, dependency directed backtracking, dynamic variable ordering, forward checking, sticky values and random-restart search strategies can be adapted to Graphplan. Empirical results are provided to demonstrate that these augmentations improve Graphplan's performance significantly (up to 1000x speedups) on several benchmark problems. Special attention is paid to the explanation-based learning and dependency directed backtracking techniques as they are empirically found to be most useful in improving the performance of Graphplan.

description: We show that in fully-self-consistent treatments of the pion; namely, its static properties and elastic and transition form factors, the asymptotic limit of the product Q^2 G_{γ* γπ^0}(Q^2), determined a priori by the interaction employed, is not exceeded at any finite value of spacelike momentum transfer. Furthermore, in such a treatment of a vector-vector contact-interaction one obtains a γ* γ-> π^0 transition form factor that disagrees markedly with all available data. We explain that the contact interaction produces a pion distribution amplitude which is flat and nonvanishing at the endpoints. This amplitude characterises a pointlike pion bound-state. Such a state has the hardest possible form factors; i.e., form factors which become constant at large momentum transfers and hence are in striking disagreement with completed experiments. On the other hand, interactions with QCD-like behaviour produce soft pions, a valence-quark distribution amplitude that vanishes as ~(1-x)^2 for x~1, and results that agree with the bulk of existing data. Our analysis supports a view that the large-Q^2 data obtained by the BaBar Collaboration is not an accurate measure of the γ* γ-> π^0 form factor.

Towards human pose estimation in video sequences
Creators: name: Oleinikov, Georgii
Publisher: name: University of British Columbia
Year: 2014

description: Recent advancements in human pose estimation from single images have attracted wide scientific interest of the Computer Vision community to the problem domain. However, the problem of pose estimation from monocular video sequences is largely under-represented in the literature despite the wide range of its applications, such as action recognition and human-computer interaction. In this thesis we present two novel algorithms for video pose estimation that demonstrate how one could improve the performance of a state-of-the-art single-image articulated human detection algorithm on realistic video sequences. Furthermore, we release the UCF Sports Pose dataset, containing full-body pose annotations of people performing various actions in realistic videos, together with a novel pose evaluation metric that better reflects the performance of current state of the art. We also release the Video Pose Annotation tool, a highly customizable application that we used to construct the dataset. Finally, we introduce a task-based abstraction for human pose estimation, which selects the "best" algorithm for every specific instance based on a task description defined using an application programming interface covering the large volume of the human pose estimation domain.

description: We investigate the space efficiency of a Propositional Knowledge Representation (PKR) formalism. Intuitively, the space efficiency of a formalism F in representing a certain piece of knowledge A, is the size of the shortest formula of F that represents A. In this paper we assume that knowledge is either a set of propositional interpretations (models) or a set of propositional formulae (theorems). We provide a formal way of talking about the relative ability of PKR formalisms to compactly represent a set of models or a set of theorems. We introduce two new compactness measures, the corresponding classes, and show that the relative space efficiency of a PKR formalism in representing models/theorems is directly related to such classes. In particular, we consider formalisms for nonmonotonic reasoning, such as circumscription and default logic, as well as belief revision operators and the stable model semantics for logic programs with negation. One interesting result is that formalisms with the same time complexity do not necessarily belong to the same space efficiency class.

description: The incorporation and diffusion of helium (He) with and without intrinsic vacancy defects in cubic ZrO$_{2}$ are investigated through first-principles total-energy calculations, in which the projector-augmented-wave (PAW) method with the generalized gradient approximation (GGA) is used. The calculated formation energies of intrinsic point defects indicate that cubic ZrO$_{2}$ has a tolerant resistance to radiation damage. The incorporation energy of He impurity shows that it is preferable to occupy the Zr vacancy at first, whereas the solution energy suggests that He would be accommodated in the interstitial site at thermodynamic equilibrium concentration. By calculating the He migration energies corresponding to both interstitial and vacancy assisted mechanisms, we suggest that it is most likely for He to diffuse by hopping through a single vacancy. Remarkably, our calculated vacancy-assisted diffusion energy of He is consistent well with the experimental measurement.

description: The Civilian Conservation Corps (CCC) was one of the US federal government's New Deal programs, designed to combat the harsh conditions of the Great Depression by putting young, unemployed men to work on projects to conserve the nation's natural resources. The CCC strove to educate these men and prepare them for jobs outside the CCC while they worked on projects to combat soil erosion, improve the nation's forests, build roads, and develop public parks. This publication is a transcription of the CCC camp newspapers of Camp SCS-26-A, Patagonia, Arizona, US, including indices and a short history of the CCC program and the camp newspapers.

Random walks in the quarter plane with zero drift: an explicit criterion for the finiteness of the associated group

Publisher: name: arXiv

Subjects: subject: Probability (math.PR)

description: In many recent studies on random walks with small jumps in the quarter plane, it has been noticed that the so-called "group" of the walk governs the behavior of a number of quantities, in particular through its "order". In this paper, when the "drift" of the random walk is equal to 0, we provide an effective criterion giving the order of this group. More generally, we also show that in all cases where the "genus" of the algebraic curve defined by the kernel is 0, the group is infinite, except precisely for the zero drift case, where finiteness is quite possible.

Value-Function Approximations for Partially Observable Markov Decision Processes
Creators: name: Hauskrecht, M.

description: Partially observable Markov decision processes (POMDPs) provide an elegant mathematical framework for modeling complex decision and planning problems in stochastic domains in which states of the system are observable only indirectly, via a set of imperfect or noisy observations. The modeling advantage of POMDPs, however, comes at a price -- exact methods for solving them are computationally very expensive and thus applicable in practice only to very simple problems. We focus on efficient approximation (heuristic) methods that attempt to alleviate the computational problem and trade off accuracy for speed. We have two objectives here. First, we survey various approximation methods, analyze their properties and relations and provide some new insights into their differences. Second, we present a number of new approximation methods and novel refinements of existing techniques. The theoretical results are supported by experiments on a problem from the agent navigation domain.

description: We perform a model independent analysis on $q \bar{q} \rightarrow t \bar{t}$ using an effective lagrangian with dim-6 four-quark operators, and derive necessary conditions on new physics that are consistent with the $t\bar{t}$ production cross section %($σ_{t\bar{t}}$) and and the forward-backward (FB) asymmetry ($A_{\rm FB}$) measured at the Tevatron. We also propose a new FB spin-spin correlation that is strongly correlated with the $A_{\rm FB}$, and discuss possible new physics scenarios that could generate such dim-6 operators.

description: Ultra-compact X-ray binaries consist of a neutron star or black hole that accretes material from a white dwarf-donor star. The ultra-compact nature is expressed in very short orbital periods of less than 1 hour. In the case of 4U 0614+091 oxygen-rich material from a CO or ONe white dwarf is flowing to the neutron star. This oxygen-rich disc can reflect X-rays emitted by the neutron star giving a characteristic emission spectrum. We have analyzed high-resolution RGS and broad band EPIC spectra of 4U 0614+091 obtained by the XMM-Newton satellite. We detect a broad emission feature at ~0.7 keV in both instruments, which cannot be explained by unusual abundances of oxygen and neon in the line of sight, as proposed before in the literature. We interpret this feature as O VIII Lyalpha emission caused by reflection of X-rays off highly ionized oxygen, in the strong gravitational field close to the neutron star.

Statistical models of the spine for image analysis and image-guided interventions

Publisher: name: University of British Columbia

description: The blind placement of an epidural needle is among the most difficult regional anesthetic techniques. The challenge is to insert the needle in the midline plane of the spine and to avoid overshooting the needle into the spinal cord. Prepuncture 2D ultrasound scanning has been introduced as a reliable tool to localize the target and facilitate epidural needle placement. Ideally, real-time ultrasound should be used during needle insertion to monitor the progress of needle towards the target epidural space. However, several issues inhibit the use of standard 2D ultrasound, including the obstruction of the puncture site by the ultrasound probe, low visibility of the target in ultrasound images of the midline plane, and increased pain due to a longer needle trajectory. An alternative is to use 3D ultrasound imaging, where the needle and target could be visible within the same reslice of a 3D volume; however, novice ultrasound users (i.e., many anesthesiologists) have difficulty interpreting ultrasound images of the spine and identifying the target epidural space. In this thesis, I propose techniques that are utilized for augmentation of 3D ultrasound images with a model of the vertebral column. Such models can be pre-operatively generated by extracting the vertebrae from various imaging modalities such as Computed Tomography (CT) or Magnetic Resonance Imaging (MRI). However, these images may not be obtainable (such as in obstetrics), or involve ionizing radiation. Hence, the use of Statistical Shape Models (SSM) of the vertebrae is a reasonable alternative to pre-operative images. My techniques include construction of a statistical model of vertebrae and its registration to ultrasound images. The model is validated against CT images of 56 patients by evaluating the registration accuracy. The feasibility of the model is also demonstrated via registration to 64 in vivo ultrasound volumes.
Robust Agent Teams via Socially-Attentive Monitoring

description: Agents in dynamic multi-agent environments must monitor their peers to execute individual and group plans. A key open question is how much monitoring of other agents' states is required to be effective: The Monitoring Selectivity Problem. We investigate this question in the context of detecting failures in teams of cooperating agents, via Socially-Attentive Monitoring, which focuses on monitoring for failures in the social relationships between the agents. We empirically and analytically explore a family of socially-attentive teamwork monitoring algorithms in two dynamic, complex, multi-agent domains, under varying conditions of task distribution and uncertainty. We show that a centralized scheme using a complex algorithm trades correctness for completeness and requires monitoring all teammates. In contrast, a simple distributed teamwork monitoring algorithm results in correct and complete detection of teamwork failures, despite relying on limited, uncertain knowledge, and monitoring only key agents in a team. In addition, we report on the design of a socially-attentive monitoring system and demonstrate its generality in monitoring several coordination relationships, diagnosing detected failures, and both on-line and off-line applications.
