Recommending user-generated item lists
Creators: name: Liu, Yidan
Publisher: name: University of British Columbia
Year: 2016

description: Nowadays, more and more websites are providing users with the functionality to create item lists. For example, in Yelp, users can create restaurant lists he/she likes. In Goodreads, users can create booklists consisting of books they like. These user-generated item lists complement the main functionality of the corresponding application and intuitively become an alternative way for users to browse and discover interesting items. Existing recommender systems are not designed for recommending user-generated item lists directly. In this work, we study properties of these user-generated item lists and propose two different models for recommending user-generated lists. We first model the problem as a recommendation problem and propose a Bayesian ranking model, called Lire. The proposed model takes into consideration users' previous interactions with both item lists and with individual items. Furthermore, we propose in Lire a novel way of weighting items within item lists based on both positions of items, and personalized list consumption pattern. Through extensive experiments on a real item list dataset from Goodreads, we demonstrate the effectiveness of our proposed Lire model. We then summarize the lessons learned from the recommendation model and modelled the problem as an optimization problem. We show that the list recommendation optimization can be reduced to Maximum k-Coverage Problem, which is an NP-hard problem. We derive three different problem variants and propose algorithms for each of them. We then conduct experiments to compare their results. Lessons learned and possible application scenarios are also discussed in the hope of helping us and more people improve the work. Furthermore, we propose several potential directions for future work.

description: We have examined polar magnetic fields for the last three solar cycles, {$\it{viz.}$}, cycles 21, 22 and 23 using NSO Kitt Peak synoptic magnetograms. In addition, we have used SoHO/MDI magnetograms to derive the polar fields during cycle 23. Both Kitt Peak and MDI data at high latitudes (78${^{\circ}}$--90${^{\circ}}$) in both solar hemispheres show a significant drop in the absolute value of polar fields from the late declining phase of the solar cycle 22 to the maximum of the solar cycle 23. We find that long term changes in the absolute value of the polar field, in cycle 23, is well correlated with changes in meridional flow speeds that have been reported recently. We discuss the implication of this in influencing the extremely prolonged minimum experienced at the start of the current cycle 24 and in forecasting the behaviour of future solar cycles.

description: We study the distribution of cosmic voids and void galaxies using Sloan Digital Sky Survey Data Release 7 (SDSS DR7). Using the VoidFinder algorithm as described by Hoyle 2002, we identify 1054 statistically significant voids in the northern galactic hemisphere with radii > 10 h^{-1} Mpc. The filling factor of voids in the sample volume is 62%. The largest void is just over 30 h^{-1} Mpc in effective radius. The median effective radius is 17 h^{-1} Mpc. The voids are found to be significantly underdense, with density contrast δ< -0.85 at the edges of the voids. The radial density profiles of these voids are similar to predictions of dynamically distinct underdensities in gravitational theory. We find 8,046 galaxies brighter than M_r = -20.09 within the voids, accounting for 7% of the galaxies. We compare the results of VoidFinder on SDSS DR7 to mock catalogs generated from a SPH halo model simulation as well as other Λ-CDM simulations and find similar void fractions and void sizes in the data and simulations. This catalog is made publicly available at http://www.physics.drexel.edu/~pan/voidcatalog.html for download.

Regulation of production, maturation and lytic release of the Rhodobacter capsulatus gene transfer agent
Creators: name: Westbye, Alexander Bauer
Publisher: name: University of British Columbia
Year: 2016

description: The Rhodobacter capsulatus gene transfer agent (RcGTA) is a phage-like particle that mediates horizontal gene transfer between R. capsulatus strains, and its production is regulated by several bacterial systems, including quorum sensing and the CckA-ChpT-CtrA phosphorelay. This thesis presents evidence that RcGTA is released from cells by cell lysis, that lysis is modulated by the concentration of inorganic phosphate in the growth medium and that lysis requires an endolysin and holin gene. The expression of the lysis genes is regulated by the histidine kinase CckA, the phosphotransferase ChpT and the response regulator CtrA, and requires phosphorylation of CtrA. The endolysin and holin were characterized by expression in E. coli. High resolution electron microscopy images of affinity-purified RcGTA confirmed that RcGTA contains tail fibers and head spikes, and newly revealed the presence of a baseplate-like structure. RcGTA was found to undergo a maturation process similar to that of phages, and this maturation was regulated by the CckA-ChpT-CtrA phosphorelay. Cells lacking CckA produced tail-less particles containing DNA and polytube structures. During particle assembly spikes are attached to the head of RcGTA, and spike formation required ghsA and ghsB, which appear to be co-transcribed and regulated by CckA-ChpT-CtrA and quorum sensing. Spikes were required for efficient binding of RcGTA to the R. capsulatus capsular polysaccharide. Two new regulators of RcGTA, ClpX and DivL, were identified. ClpX was required for transduction, and capsid formation in cells lacking ClpX appeared to halt RcGTA production prior to DNA packaging. DivL appeared to be involved in regulating the CckA kinase activity; however a loss of DivL resulted in opposite phenotypes for an RcGTA overproducer and a wild type strain. Additionally, RcGTA production was found to be stimulated by temporary depletion of amino acids, but did not require the (p)ppGpp-mediated stringent response or a homologue of the general stress response sigma factor EcfG.

description: Abstract: Measuring bias is important as it helps identify flaws in quantitative forecasting methods or judgmental forecasts. It can, therefore, potentially help improve forecasts. Despite this, bias tends to be under represented in the literature: many studies focus solely on measuring accuracy. Methods for assessing bias in single series are relatively well known and well researched, but for datasets containing thousands of observations for multiple series, the methodology for measuring and reporting bias is less obvious. We compare alternative approaches against a number of criteria when rolling origin point forecasts are available for different forecasting methods and for multiple horizons over multiple series. We focus on relatively simple, yet interpretable and easy to implement metrics and visualization tools that are likely to be applicable in practice. To study the statistical properties of alternative measures we use theoretical concepts and simulation experiments based on artificial data with predetermined features. We describe the difference between mean and median bias, describe the connection between metrics for accuracy and bias, provide suitable bias measures depending on the loss function used to optimise forecasts, and suggest which measures for accuracy should be used to accompany bias indicators. We propose several new measures and provide our recommendations on how to evaluate forecast bias across multiple series.

description: In recent years research in the planning community has moved increasingly toward s application of planners to realistic problems involving both time and many typ es of resources. For example, interest in planning demonstrated by the space res earch community has inspired work in observation scheduling, planetary rover ex ploration and spacecraft control domains. Other temporal and resource-intensive domains including logistics planning, plant control and manufacturing have also helped to focus the community on the modelling and reasoning issues that must be confronted to make planning technology meet the challenges of application. The International Planning Competitions have acted as an important motivating fo rce behind the progress that has been made in planning since 1998. The third com petition (held in 2002) set the planning community the challenge of handling tim e and numeric resources. This necessitated the development of a modelling langua ge capable of expressing temporal and numeric properties of planning domains. In this paper we describe the language, PDDL2.1, that was used in the competition. We describe the syntax of the language, its formal semantics and the validation of concurrent plans. We observe that PDDL2.1 has considerable modelling power --- exceeding the capabilities of current planning technology --- and presents a number of important challenges to the research community.

description: Star formation is regulated through a variety of feedback processes. In this study, we treat feedback by metal injection and a UV background as well as by X-ray irradiation. Our aim is to investigate whether star formation is significantly affected when the ISM of a proto-galaxxy enjoys different metallicities and when a star forming cloud resides in the vicinity of a strong X-ray source. We perform cosmological Enzo simulations with a detailed treatment of non-zero metallicity chemistry and thermal balance. We also perform FLASH simulations with embedded Lagrangian sink particles of a collapsing molecular cloud near a massive, 10^{7} M\odot, black hole that produces X-ray radiation. We find that a multi-phase ISM forms for metallicites as small as 10^{-4} Solar at z = 6, with higher (10^{-2}Z\odot) metallicities supporting a cold (< 100 K) and dense (> 10^{3} cm^{-3}) phase at higher (z = 20) redshift. A star formation recipe based on the presence of a cold dense phase leads to a self-regulating mode in the presence of supernova and radiation feedback. We also find that when there is strong X-ray feedback a collapsing cloud fragments into larger clumps whereby fewer but more massive protostellar cores are formed. This is a consequence of the higher Jeans mass in the warm (50 K, due to ionization heating) molecular gas. Accretion processes dominate the mass function and a near-flat, non-Salpeter IMF results.

description: The integration of multilocus datasets and species distribution modelling in phylogeography allows for the reconstruction of more detailed historical biogeographical scenarios than based on mtDNA data alone. We here combine these approaches to investigate the range dynamics of the crested newt Triturus karelinii, an amphibian species endemic to the Pontocaspian region, whose range comprises three allopatric range sections: a Crimean, a Caucasian and a Caspian range section. In a previous mtDNA phylogeographical survey it was suggested that the Caucasian range section was colonized from the Caspian one and that the Crimean range section was subsequently colonized from the Caucasian one. Newly collected nuclear DNA data reveal little genetic differentiation between the three range sections and species distribution modelling suggests that they only recently became isolated. Taken together, our analyses agree with a recent colonization of the Crimean range section, but rather suggest long-term persistence in both the Caspian and Caucasian range sections, with extensive gene flow between the two.
Baryon Acoustic Oscillations in 2D II: Redshift-space halo clustering in N-body simulations

description: We measure the halo power spectrum in redshift space from cosmological N-body simulations, and test the analytical models of redshift distortions particularly focusing on the scales of baryon acoustic oscillations (BAOs). Remarkably, the measured halo power spectrum in redshift space exhibits a large-scale enhancement in amplitude relative to the real-space clustering, and the effect becomes significant for the massive or highly biased halo samples. These findings cannot be simply explained by the so-called streaming model frequently used in the literature. By contrast, a physically-motivated perturbation theory model developed in the previous paper reproduces the halo power spectrum very well, and the model combining a simple linear scale-dependent bias can accurately characterize the clustering anisotropies of halos in two dimensions, i.e., line-of-sight and its perpendicular directions. The results highlight the significance of non-linear coupling between density and velocity fields associated with two competing effects of redshift distortions, i.e., Kaiser and Finger-of-God effects, and a proper account of this effect would be important in accurately characterizing the BAOs in two dimensions.

In situ mineral sediment characterization with light scattering and image analysis
Creators: name: MacIver, Michael Ryan
Publisher: name: University of British Columbia
Year: 2016

description: In this study, optical backscattering (OBS) and in situ image analysis are used to measure sediment bed density and aggregate size. A method is described for the measurement and interpretation of OBS height scans to obtain a measurement of aggregate size and solid concentration profiles in sediment beds of flocculated minerals. It was found that when OBS height scans were measured during batch settling and from multiple angles at the end of batch settling, the resulting root-mean-square, 𝐹rms, and mean, 𝐹mean, signal values can be analysed to quantify the sediment bed solids concentration and aggregate size as a function of height in the sample. A size calibration method was applied which relates the 𝐹rms values obtained from model solid ceramic spheres and silica particles to 𝐹rms values measured from sediment beds of flocculated kaolin. An iterative fitting method is applied to obtain a calibration function which can be applied to obtain a quantitative description of solid volume as a function of height and time during the batch settling experiment, 𝜙s(ℎ,𝑡). Evaluation of the fitted solid volume versus height functions resulted in a reasonable relative error when compared with the measured solid volume in the sample. A brief analysis on a statistical interpretation of image data for various samples of flocculated mineral sediment beds is given. This study suggests that the evaluation of OBS signal values and high magnification image analysis can be applied on the lab scale for determination of aggregate size and sediment bed density and may form the basis of a measurement system that can be applied to larger scale batch settling or pilot thickening equipment to measure rheological properties and mass flux.

Also, two other fractional statistics, namely Gentile and Polychronakos fractional statistics, will be considered and similarities and differences between these statistics will be explored. Thermodynamic geometry suggests that a two dimensional Haldane fractional exclusion gas is more stable than higher dimensional gases. Also, a complete picture of attractive and repulsive statistical interaction of fractional statistics is given. For a special kind of fractional statistics, by considering the singular points of thermodynamic curvature, we find a condensation for a non-pure bosonic system which is similar to the Bose-Einstein condensation and the phase transition temperature will be worked out.

description: There is no known model in holography exhibiting a $c$-theorem where the central charges of the dual CFT are distinct. We examine a holographic model of RG flows in a framework where the bulk gravity theory contains higher curvature terms. The latter allows us to distinguish the flow of the central charges $a$ and $c$ in the dual field theories in four dimensions. One finds that the flow of $a$ is naturally monotonic but that of $c$ is not. Extending the analysis of holographic RG flows to higher dimensions, we are led to formulate a novel c-theorem in arbitrary dimensions for a universal coefficient appearing in the entanglement entropy of the fixed point CFT's.

These hadrons are tetraquark (four-quark) candidates, with a hidden $s\bar{s}$, $c\bar{c}$ and $b\bar{b}$ quark pair, respectively. In deriving the distributions and cross sections, we include the order $α_s$ QCD corrections, resum the large logarithms in the small transverse momentum region in the impact-parameter formalism, and use the state of the art parton distribution functions. Taking into account the data on the production and decays of these vector hadrons from the $e^+e^-$ experiments, we present the production rates for the processes $pp(\bar{p}) \to ϕ(2170)(\to ϕ(1020) π^+π^- \to K^+K^- π^+π^-)+...$, $pp(\bar{p}) \to X(4260)(\to J/ψπ^+π^- \to μ^+μ^-π^+π^-)+...$, and $pp(\bar{p}) \to Y_b(10890)(\to (Υ(1S), Υ(2S), Υ(3S)) π^+π^- \to μ^+μ^-π^+π^-)+...$. Their measurements at the hadron colliders will provide new experimental avenues to explore the underlying dynamics of these hadrons.

description: X-ray astronomers often divide galaxy clusters into two classes: "cool core" (CC) and "non-cool core" (NCC) objects. The origin of this dichotomy has been the subject of debate in recent years, between "evolutionary" models (where clusters can evolve from CC to NCC, mainly through mergers) and "primordial" models (where the state of the cluster is fixed "ab initio" by early mergers or pre-heating). We found that in a well-defined sample (clusters in the GMRT Radio halo survey with available Chandra or XMM-Newton data), none of the objects hosting a giant radio halo can be classified as a cool core. This result suggests that the main mechanisms which can start a large scale synchrotron emission (most likely mergers) are the same that can destroy CC and therefore strongly supports "evolutionary" models of the CC-NCC dichotomy. Moreover combining the number of objects in the CC and NCC state with the number of objects with and without a radio-halo, we estimated that the time scale over which a NCC cluster relaxes to the CC state, should be larger than the typical life-time of radio-halos and likely shorter than about 3 Gyr. This suggests that NCC transform into CC more rapidly than predicted from the cooling time, which is about 10 Gyr in NCC systems, allowing the possibility of a cyclical evolution between the CC and NCC states.

Impact of caspase-6 modulation on Huntington disease phenotypes in the YAC128 mouse model
Creators: name: Ladha, Safia
Publisher: name: University of British Columbia
Year: 2016

description: Huntington disease (HD) is an autosomal dominant neurodegenerative disorder characterized by motor, cognitive, and psychiatric symptoms. HD is caused by a CAG repeat expansion in the huntingtin (HTT) gene leading to the production of the mutant huntingtin protein (mHTT). Caspase-6 (C6) is a cysteine aspartyl protease that plays a central role in apoptosis and has been postulated to play a role in inflammation. Increased C6 activation is observed in human HD brains and mouse models and the inhibition of C6-mediated cleavage of mHTT protects against neuropathology and behavioural deficits in the YAC128 mouse model of HD. Additionally, alterations in inflammation are a feature of many neurodegenerative diseases, including HD. Hyperactive inflammatory responses are observed in both HD patients and mouse models and C6 has been postulated to play a role in mediating inflammation. Constitutive deletion of the Casp6 gene (denoted as C6) in YAC128 mice results in a partial rescue of some features of HD; however, the continued presence of the 586 cleavage fragment in the absence of C6 suggests possible compensation by other proteases. The goal of this thesis was to investigate the impact of modulating C6 in the adult YAC128 mouse and to further characterize the role of C6 in inflammation. To that end, the C6 gene was partially deleted in the adult YAC128 mouse and characterization of these mice reveals no amelioration in motor or cognitive phenotypes but a modest improvement in certain psychiatric behaviours. Neuropathological assessment shows no attenuation in canonical brain pathology but peripherally, the loss of C6 attenuates the overactive inflammatory response observed in YAC128 mice. These data suggest that partial loss of C6 in the brain is not sufficient to improve most behavioural and neuropathological phenotypes but implicate C6 in the regulation of inflammation. Furthermore, loss of C6 results in a blunted inflammatory response characterized by reduced cytokine release. As the presence of elevated cytokine levels have been suspected to cause psychiatric behaviours such as depression, this finding provides a possible mechanistic link between C6 activity and the onset of affective behaviours.

description: We present the complete set of Feynman rules producing the rational terms of kind R_2 needed to perform any 1-loop calculation in the Electroweak Standard Model. Our formulae are given both in the R_xi gauge and in the Unitary gauge, therefore completing the results in the 't Hooft-Feynman gauge already presented in a previous publication. As a consistency check, we verified, in the case of the process H -> gamma gamma and in a few other physical cases, the independence of the total Rational Part R_1+R_2 on the chosen gauge. In addition, we explicitly checked the equivalence of the limits xi -> infinity after or before the loop momentum integration in the definition of the Unitary gauge at 1-loop.

description: Gamma ray source detection above 30TeV is an encouraging approach for finding galactic cosmic ray origins. All sky survey for gamma ray sources using wide field of view detector is essential for population accumulation for various types of sources above 100GeV. To target the goals, the ARGO-YBJ experiment has been established. Significant progresses have been made in the experiment. A large air shower detector array in an area of 1km2 is proposed to boost the sensitivity. Hybrid detection with multi-techniques will allow a good discrimination between different types of primary particles, including photons and protons, thus enable an energy spectrum measurement for individual specie. Fluorescence light detector array will extend the spectrum measurement above 100PeV where the second knee is located. An energy scale determined by balloon experiments at 10TeV will be propagated to ultra high energy cosmic ray experiments.
Experimental analysis of lateral impact on planar brittle material: spatial properties of the cracks

description: The breakup of glass and alumina plates due to planar impacts on one of their lateral sides is studied. Particular attention is given to investigating the spatial location of the cracks within the plates. Analysis based on a phenomenological model suggests that bifurcations along the cracks' paths are more likely to take place closer to the impact region than far away from it, i. e., the bifurcation probability seems to lower as the perpendicular distance from the impacted lateral in- creases. It is also found that many observables are not sensitive to the plate material used in this work, as long as the fragment multiplicities corresponding to the fragmentation of the plates are similar. This gives support to the universal properties of the fragmentation process reported in for- mer experiments. However, even under the just mentioned circumstances, some spatial observables are capable of distinguishing the material of which the plates are made and, therefore, it suggests that this universality should be carefully investigated.

description: The Mt. Suhora M\,dwarf survey searching for pulsations in low mass main sequence stars has acquired CCD photometry of 46 M\,dwarf stars during the first year of the project (Baran et al 2011). As a by-product of this search hundreds field stars have been checked for variability. This paper presents our initial result of a search for periodic variables in field stars observed in the course of the survey. On the basis of the periodicity and the shape of the light curves, eight new variables has been detected, among which five are $δ$ Scuti stars and three likely RR Lyrae stars. Although variation in one of the stars has been previously detected, it was classified incorrectly. To support our classification, in August 2010, we performed spectroscopic observations to derive spectral types and luminosity classes for all eight variable stars.

title: Modification of the Canadian Water Quality Index : Case Study Assessment of Groundwater Quality in Mekong Delta, Vietnam
Creators: name: Dao Thi Bich, Van
Publisher: name: UNSPECIFIED
Year: 2020

description: In water resources management, there exists a significant disconnect between interests and goal stettings of stakeholders, policy-makers, and decision-makers. Researches have shown that water quality indices have become useful tools for water quality assessment and management. This study aims to determine the groundwater quality status of the Vietnamese Mekong Delta with a suitable water quality index regarding the European Water Framework Directive and the Vietnamese National Regulation. Building on existing works, the needed Water Quality Index must have the following fundamental properties: independence of the particular set of quality parameters and sensitivity to individual bad parameters. Based on a review of the literature on water management and theories of water quality indices, the Canadian Water Quality Index (CCME WQI) is chosen as the basis of argumentation, because it has the first of the above properties. Analysis of the implicit statistical data, especially the inclusion of the number of quality parameters with one failed test (Scope) as well as the number of failed tests (Frequency) in the definition of CCME WQI, demonstrated that CCME WQI is also a quality index for the quality of water control: a high number of failed tests or a high number of quality parameters with failed tests indicate that water control is not sufficient. Nevertheless, there are situations where water must be regarded as good, while CCME WQI qualifies it as bad by its statistical factors. Therefore, this research presents a modification of CCME WQI, called Modified Canadian Water Quality Index (MCWQI), which widely has the same behavior as CCME WQI but is better in situations where the statistical factors furnish the wrong picture of the situation. The useability of MCWQI is verified by an application to the case study “Groundwater Quality in Mekong Delta”. The results concerning the Vietnamese groundwater regulation and the European drinking water regulation are compared. MCWQI is defined as a new tool to help not only water stakeholders and policy-makers but also communities to target scant resources more effectively and sustainably.

Density-based mixing parameter for hybrid functionals

description: A very popular ab-initio scheme to calculate electronic properties in solids is the use of hybrid functionals in density functional theory (DFT) that mixes a portion of Fock exchange with DFT functionals. In spite of their success, a major problem still remains, related to the use of one single mixing parameter for all materials. Guided by physical arguments that connect the mixing parameter to the dielectric properties of the solid, and ultimately to its band gap, we propose a method to calculate this parameter from the electronic density alone. This method is able to cut significantly the error of traditional hybrid functionals for large and small gap materials, while retaining a good description of structural properties. Moreover, its implementation is simple and leads to a negligible increase of the computational time.

Creation of NOON states by double Fock-state/Bose-Einstein condensates

description: NOON states (states of the form $|N>_{a}|0>_{b}+|0>_{a}|N>_{b}$ where $a$ and $b$ are single particle states) have been used for predicting violations of hidden-variable theories (Greenberger-Horne-Zeilinger violations) and are valuable in metrology for precision measurements of phase at the Heisenberg limit. We show theoretically how the use of two Fock state/Bose-Einstein condensates as sources in a modified Mach Zender interferometer can lead to the creation of the NOON state in which $a$ and $b$ refer to arms of the interferometer and $N$ is the total number of particles in the two condensates. The modification of the interferometer involves making conditional ``side'' measurements of a few particles near the sources. These measurements put the remaining particles in a superposition of two phase states, which are converted into NOON states by a beam splitter. The result is equivalent to the quantum experiment in which a large molecule passes through two slits. The NOON states are combined in a final beam splitter and show interference. Attempts to detect through which ``slit'' the condensates passed destroys the interference.
