Clustered Radio Interferometric Calibration

description: This paper introduces an amendment to radio interferometric calibration of sources below the noise level. The main idea is to employ the information of the stronger sources' measured signals as a plug-in criterion to solve for the weaker ones. For this purpose, we construct a number of source clusters, with centroids mainly near the strongest sources, assuming that the signals of the sources belonging to a single cluster are corrupted by almost the same errors. Due to this characteristic of clusters, each cluster is calibrated as a single source, using all the coherencies of its sources simultaneously. The obtained solutions for every cluster are assigned to all the cluster's sources. An illustrative example reveals the superiority of this calibration compared to the un-clustered calibration.

description: We develop the thermodynamics of field theories characterized by non-local propagators. We analyze the partition function and main thermodynamic properties arising from perturbative thermal loops. We focus on the p-adic models associated with the tachyon phenomenology in string theories. We reproduce well known features of these theories, but also obtain many new results. In particular, we explain how to maintain consistency of such non-local theories by avoiding the appearance of ghosts at finite temperature. As a consequence of this fact, the vacuum energy in p-adic theories becomes positive. It is also hierarchically suppressed, and we explore the parameter space where it is consistent with the observed value of the cosmological constant.

Majorana-Hubbard model on the triangular lattice
Creators: name: Tummuru, Tarun Reddy
Publisher: name: University of British Columbia
Year: 2019

description: Majorana modes can arise as zero energy bound states in a variety of solid state systems. A lattice of these quasiparticles, for instance, emerges on the surface of a topological superconductor with the zero modes localized at the cores of vortices. This thesis is devoted to the study of interactions between the Majorana zero modes when such a lattice has a triangular geometry. We map the phase diagram of this model using a combination of mean field theory and numerical simulation of ladders through the density-matrix renormalization-group technique. Our analysis suggests that interactions drive a topologically non-trivial gapped phase into a gapless Luttinger liquid.
Improving the phenomenology of K_{l3} form factors with analyticity and unitarity

description: The shape of the vector and scalar K_{l3} form factors is investigated by exploiting analyticity and unitarity in a model-independent formalism. The method uses as input dispersion relations for certain correlators computed in perturbative QCD in the deep Euclidean region, soft-meson theorems, and experimental information on the phase and modulus of the form factors along the elastic part of the unitarity cut. We derive constraints on the coefficients of the parameterizations valid in the semileptonic range and on the truncation error. The method also predicts low-energy domains in the complex $t$-plane where zeros of the form factors are excluded. The results are useful for K_{l3} data analyses and provide theoretical underpinning for recent phenomenological dispersive representations for the form factors.

Inversion of hyperelliptic integrals of arbitrary genus with application to particle motion in General Relativity

description: The description of many dynamical problems like the particle motion in higher dimensional spherically and axially symmetric space-times is reduced to the inversion of a holomorphic hyperelliptic integral. The result of the inversion is defined only locally, and is done using the algebro-geometric techniques of the standard Jacobi inversion problem and the foregoing restriction to the $θ$--divisor. For a representation of the hyperelliptic functions the Klein--Weierstraß multivariable sigma function is introduced. It is shown that all parameters needed for the calculations like period matrices and Abelian images of branch points can be expressed in terms of the periods of holomorphic differentials and theta-constants. The cases of genus two and three are considered in detail. The method is exemplified by particle motion associated with a genus three hyperelliptic curve.

description: There are many ways to reduce the amount of code to be analyzed when debugging. One of them is program slicing. Most of the approaches suffer from slicing time dependence on program trace size. In this thesis we implement an algorithm that overcomes the problem â dynamic slicing by on-demand re-execution. Based on this algorithm, we developed a program slicing application for Java programming language, then compared it with other slicing methods. The evaluation results show usefulness and applicability of the approach.

Publisher: name: arXiv

description: We explore a way of finding the link between a non-Hermitian Hamiltonian and a Hermitian one. Based on the analysis of Bethe Ansatz solutions for a class of non-Hermitian Hamiltonians and the scattering problems for the corresponding Hermitian Hamiltonians. It is shown that a scattering state of an arbitrary Hermitian lattice embedded in a chain as the scattering center shares the same wave function with the corresponding non-Hermitian tight binding lattice, which consists of the Hermitian lattice with two additional on-site complex potentials, no matter the non-Hermitian is broken PT symmetry or even non-PT. An exactly solvable model is presented to demonstrate the main points of this article.

Probing neutron's electric neutrality with Ramsey Spectroscopy of gravitational quantum states of ultra-cold neutrons

description: We propose to test the electric neutrality of neutrons by a new technique using the spectroscopy of quantum states of ultra-cold neutrons in the gravity potential above a vertical mirror. The new technique is an application of Ramsey's method of separated oscillating fields to neutron's quantum states in the gravity potential of the earth. In the presence of an electric field E parallel or antiparallel to the direction of the acceleration of the earth g, the energy of the quantum states changes due to an additional electrostatic potential if a neutron carries a non-vanishing charge. In the long run our new method has the potential to improve the current limit for the electric charge of the neutron by 2 orders of magnitude.

description: A QCD analysis of the world data on polarized deep inelastic scattering is presented in next--to--leading order, including the heavy flavor Wilson coefficient in leading order in the fixed flavor number scheme. New parameterizations are derived for the quark and gluon distributions and the value of $α_s(M_z^2)$ is determined. The impact of the variation of both the renormalization and factorization scales on the distributions and the value of $α_s$ is studied. We obtain $α_s^{\rm NLO}(M_Z^2) = 0.1132~~\begin{array}{l} + 0.0056 \\ -0.0095 \end{array}$. The first moments of the polarized twist--2 parton distribution functions are calculated with correlated errors to allow for comparisons with results from lattice QCD simulations. Potential higher twist contributions to the structure function $g_1(x,Q^2)$ are determined and found to be compatible with zero both for proton and deuteron targets.

Emotional ethics of warfare : how empathy can be used to strengthen protection of the natural environment
Creators: name: Priest, Margaret
Publisher: name: University of British Columbia
Year: 2019

description: This research examines the anthropocentric nature of traditional ethics of warfare and how this normative framework has translated to international conventions, treaties, and laws addressing environmental harm. Human beings have always been at the center of moral concern, which has led to environmental protection being recognized only as an important issue for human security. In order to adequately address the impacts for the natural environment we must expand our circle of moral concern to include the natural environment. Just as relationships between humans can evolve and empathy becomes more readily available, so too, can this occur in the relationship between humans and the environment. This research explores how the institutionalization of empathy within international organizations is one important mechanism for establishing ecocentric protections for the natural environment. Extending empathy to the natural environment means we recognize its intrinsic value. Thus, there is a greater chance for international law to adequately address violence against the natural environment.

description: Asymptotic safety (an ultraviolet fixed point with finite-dimensional critical surface) offers the possibility that a predictive theory of quantum gravity can be obtained from the quantization of classical general relativity. However, it is unclear what becomes of the singularities of classical general relativity, which, it is hoped, might be resolved by quantum effects. We study dust collapse with a running gravitational coupling and find that a future singularity can be avoided if the coupling becomes exactly zero at some finite energy scale. The singularity can also be avoided (pushed off to infinite proper time) if the coupling approaches zero sufficiently rapidly at high energies. However, the evolution deduced from perturbation theory still implies a singularity at finite proper time.

description: Interface adaptation allows code written for one interface to be used with a software component with another interface. When multiple adapters are chained together to make certain adaptations possible, we need a way to analyze how well the adaptation is done in case there are more than one chains that can be used. We introduce an approach to precisely analyzing the loss in an interface adapter chain using a simple form of abstract interpretation.

description: We combine work of Cox on the total coordinate ring of a toric variety and results of Eisenbud-Mustata-Stillman and Mustata on cohomology of toric and monomial ideals to obtain a formula for computing the Euler characteristic of a Weil divisor D on a complete simplicial toric variety in terms of graded pieces of the Cox ring and Stanley-Reisner ring. The main point is to use Alexander duality to pass from the toric irrelevant ideal, which appears in the computation of the Euler characteristic of D, to the Stanley-Reisner ideal of the fan, which is used in defining the Chow ring. The formula also follows from work of Maclagan-Smith.

description: Problem In Bearn, maize is well adapted to the pedoclimatic context, with no loss of yield potential when grown as a monocrop. But, regulatory pressure and price volatility risks, as well as increasing attacks from bio-aggressors, threaten maize monocropping. It is essential to experiment with alternative cropping systems combining respect for the environment, efficient management of bio-aggressors, productivity and profitability. Solution As an alternative to maize monocropping, a 2-years rotation has been implemented (Figure 1). It consists of a sequence of 4 crops in 2 years: maize, cover crop (oats & mustard), soybean and oats as an energy catch crop (ECC). Thanks to the introduction of legumes and cover crops, which enable crop diversification whilst qualifying for coupled aids, this innovative system has proved to enhance agronomic, environmental and economic performances.

description: We demonstrate sub-Poissonian number differences in four-wave mixing of Bose-Einstein condensates of metastable helium. The collision between two Bose-Einstein condensates produces a scattering halo populated by pairs of atoms of opposing velocities, which we divide into several symmetric zones. We show that the atom number difference for opposing zones has sub-Poissonian noise fluctuations whereas that of nonopposing zones is well described by shot noise. The atom pairs produced in a dual number state are well adapted to sub shot-noise interferometry and studies of Einstein-Podolsky-Rosen-type nonlocality tests.

description: We theoretically study the measurement-induced dephasing caused by back action noise in quantum nondemolition measurements of a superconducting flux qubit which is coupled to a superconducting quantum interference device (SQUID). Our analytical results indicate that information on qubit flows from qubit to detector, while quantum fluctuations which may cause dephasing of the qubit also inject to qubit. Furthermore, the measurement probability is frequency dependent in a short time scale and has a close relationship with the measurement-induced dephasing. When the detuning between driven and bare resonator equals coupling strength, we will access the state of qubit more easily. In other words, we obtain the maximum measurement rate. Finally, we analyzed mixed effect caused by coupling between non-diagonal term and external variable. We found that the initial information of qubit is destroyed due to quantum tunneling between the qubit states.

description: Strong lensing has developed into an important astrophysical tool for probing both cosmology and galaxies (their structures, formations, and evolutions). Now several hundreds of strong lens systems produced by massive galaxies have been discovered, which may form well-defined samples useful for statistical analyses. To collect a relatively complete lens redshift data from various large systematic surveys of gravitationally lensed quasars and check the possibility to use it as a future complementarity to other cosmological probes. We use the distribution of gravitationally-lensed image separations observed in the Cosmic Lens All-Sky Survey (CLASS), the PMN-NVSS Extragalactic Lens Survey (PANELS), the Sloan Digital Sky Survey (SDSS) and other surveys, considering a singular isothermal ellipsoid (SIE) model for galactic potentials as well as improved new measurements of the velocity dispersion function of galaxies based on the SDSS DR5 data and recent semi-analytical modeling of galaxy formation, to constrain two dark energy models ($Λ$CDM and constant $w$) under a flat universe assumption. We find that the current lens redshift data give a relatively weak constraint on the model parameters. However, by combing the redshift data with the baryonic acoustic oscillation peak and the comic macrowave background data, we obtain more stringent results, which show that the flat $Λ$ CDM model is still included at 1$σ$.

description: We study the quantum phase transition of a N two-level atomic ensemble interacting with an optical degenerate parametric process, which can be described by the finite size Dicke Hamiltonian plus counter-rotating and quadratic field terms. Analytical closed forms of the critical coupling value and their corresponding separable ground states are derived in the weak and strong coupling regimes. The existence of bipartite entanglement between the two-level-system ensemble and photon field as well as between ensemble components for moderate coupling is shown through numerical analysis. Given a finite size, our results also indicate the co-existence of squeezed fields and squeezed atomic ensembles.

We demonstrate that, despite of pronounced spatio-temporal correlations, the particle current can be reversed by adding suitable feedback control terms to the DDFT equation of motion. We explore two distinct control protocols with time delay, focussing on either the particle positions or the density profile. Our study shows that the DDFT is an appropriate framework to implement time-delayed feedback control strategies widely used in other fields of nonlinear physics

Rotation diversification
Multiple cropping

description: Problem In Bearn, maize monocropping is the standard cropping system. Yet, this system must cope with the risk of price volatility as well as with the evolution of Common Agricultural Policy (CAP) regulations, which require the diversification of crop rotation. Besides agronomic aspects, profitability can also be improved with the valorisation of the intercrop period. In the current system, the soil is left bare. Solution To break maize monocropping, an innovative system based on the introduction of oats as an energy catch crop (ECC) for methanation was introduced (picture 1), in order to harvest two crops in a year instead of one. It has proved to enhance agronomic, economic and environ-mental performances.

description: Development of an alternating current source model for series-connected plasma torches in the MATLAB Simulink environment. This work is devoted to the development and research of a high-frequency power supply for series-connected AC plasma torches, with the aim of using it in an installation for the production of metal powders for additive technologies. For this purpose, all elements of the circuit were calculated, and the source operation for the arc load was simulated in the MATLAB Simulink environment. In addition, the model was verified. Based on the data obtained, it can be concluded that the development of the power supply was successful, which makes it possible to implement it in real life, as well as to introduce it into production.

description: We have studied the structural and electronic properties of defect chalcopyrite semiconductors AAl2Se4 (A = Ag, Cu, Cd, Zn) using Density Functional Theory (DFT) based first principle technique within Tight binding Linear Muffin Tin orbital (TB-LMTO) method. Our calculated structural parameters such as lattice constants, anion displacement parameter (u), tetragonal distortion (η = c/2a), bond lengths and bulk modulus are in good agreement with other work. Our band structure calculation suggests that these compounds are direct band gap semiconductors having band gaps 2.40, 2.50, 2.46 and 2.82 eV for AAl2 Se4 (A = Ag, Cu, Cd, Zn) respectively. Calculated band gaps are in good agreement with other experimental and theoretical works within LDA limitation. We have made a quantitative estimation of the effect of p-d hybridization and structural distortion on the electronic properties. The reduction in band gap due to p-d hybridization are 19.47%, 21.29%, 0% and 0.7% for AAl2 Se4 (A = Ag, Cu, Cd, Zn) respectively. Increment of the band gap due to structural distortion is 11.62%, 2.45%, 2.92% and 9.30% in case of AgAl2 Se4, CuAl2 Se4, CdAl2 Se4 and ZnAl2 Se4 respectively . We have also discussed the bond nature of all four compounds.

Cassiope tetragona as a dendroecological proxy : a retrospective analysis of experimental warming in the Arctic Tundra
Creators: name: Gallois, Elise
Publisher: name: University of British Columbia
Year: 2019

description: Annual stem growth and reproductive effort of the evergreen dwarf-shrub, Cassiope tetragona, exhibit a strong positive relationship to summer temperature and have been used in dendroclimatological analyses to reconstruct climate in the High Arctic through the application of transfer function equations. Retrospective analysis of the annual growth increments have also previously been used to examine the impact of short term warming in a few tundra sites. This thesis presents a full retrospective analysis approach to reconstruct the impact of long-term experimental warming in tundra communities at Alexandra Fiord (Ellesmere Island) from before the installation of open-top-chambers in 1992 to the present day, using a before-after-control-intervention design on growth and reproduction variables. We found a positive, significant effect of experimental warming on the stem growth of C. tetragona and revealed that phenology stages (such as bud break, flowering, and fruit production) take place significantly earlier in the warming plots in comparison to the control plots. Furthermore, the relationship between both July Average and August Maximum air temperature time series at Alexandra Fiord and the annual stem growth and reproductive chronologies from the control plots were used to construct summer air temperature models with good predictive abilities, explaining up to 68% of the variance. We compared chronologies of C. tetragona samples from multiple International Tundra Experiment sites to investigate the extent to which growth and reproductive responses to experimental warming vary across the Arctic. An effect size analysis and linear mixed effects model was used to determine the fact that experimental warming has a significant and positive effect on plant growth, increasing annual stem growth by an average of 0.665 mm across the Arctic, with 60% of the overall variance in the stem growth data being explained by Region. This regional signal was also revealed in a Principal Components Analysis which included descriptive stem characteristics statistics at 23 circumarctic sites. These findings complement existing research about the warming effect of treatment on tundra plant growth and phenology, and provide novel information on the value of C. tetragona as a dendroecological proxy and the regional differences in C. tetragona growth and reproduction patterns.

description: The generalized Taylor expansion including a secret auxiliary parameter $h$ which can control and adjust the convergence region of the series is the foundation of the homotopy analysis method proposed by Liao. The secret of $h$ can't be understood in the frame of the homotopy analysis method. This is a serious shortcoming of Liao's method. We solve the problem. Through a detailed study of a simple example, we show that the generalized Taylor expansion is just the usual Taylor's expansion at different point $t_1$. We prove that there is a relationship between $h$ and $t_1$, which reveals the meaning of $h$ and the essence of the homotopy analysis method. As an important example, we study the series solution of the Blasius equation. Using the series expansion method at different points, we obtain the same result with liao's solution given by the homotopy analysis method.

Prospects of measuring the CKM matrix element $|V_{ts}|$ at the LHC

description: We study the prospects of measuring the CKM matrix element $\vert V_{ts}\vert$ at the LHC with the top quarks produced in the processes $p p \to t\bar{t}X$ and $p p \to t/\bar{t} X$, and the subsequent decays $t \to W^+s$ and $\bar{t} \to W^- \bar{s}$. We insist on tagging the $W^\pm$ leptonically, $W^\pm \to \ell^\pm ν_\ell$ ($\ell =e, μ, τ$), and analyse the anticipated jet profiles in the signal process $t \to W s$ and the dominant background from the decay $t \to W b$. To that end, we analyse the $V0$ ($K^0$ and $Λ$) distributions in the $s$- and $b$-quark jets concentrating on the energy and transverse momentum distributions of these particles. The $V0$s emanating from the $t \to W b$ branch have displaced decay vertexes from the interaction point due to the weak decays $b \to c \to s$ and the $b$-quark jets are rich in charged leptons. Hence, the absence of secondary vertexes and of the energetic charged leptons in the jet provide additional ($b$-jet vs. $s$-jet) discrimination in top quark decays. These distributions are used to train a boosted decision tree (BDT). Using the BDT classifier, and a variant of it called BDTD, which makes use of decorrelated variables, we calculate the BDT(D)-response functions corresponding to the signal ($t \to W s$) and background ($t \to W b$). Detailed simulations undertaken by us with the Monte Carlo generator PYTHIA are used to estimate the background rejection versus signal efficiency for three representative LHC energies $\sqrt{s}=7$ TeV, 10 TeV and 14 TeV. We argue that a benchmark with 10\% signal ($t \to W s $) efficiency and a background ($t \to W b$) rejection by a factor $10^3$ (required due to the anticipated value of the ratio $\vert V_{ts}\vert^2/\vert V_{tb} \vert^2 \simeq 1.6 \times 10^{-3}$) can be achieved at the LHC@14 TeV with an integrated luminosity of 10 fb$^{-1}$.

description: We derive a set of sum rules for the light-by-light scattering and fusion: $γγ\to all$, and verify them in lowest order QED calculations. A prominent implication of these sum rules is the superconvergence of the helicity-difference total cross-section for photon fusion, which in the hadron sector reveals an intricate cancellation between the pseudoscalar and tensor mesons. An experimental verification of superconvergence of the polarized photon fusion into hadrons is called for, but will only be possible at $e^+ e^-$ and $γγ$ colliders with both beams polarized. We also show how the sum rules can be used to measure various contributions to the low-energy light-by-light scattering.

description: We calculate the transverse and time-time components of the instantaneous gluon propagator in Coulomb gauge QCD by using an SU(3) quenched lattice simulation on isotropic and anisotropic lattices. We find that the gluon propagators suffer from strong discretization effects on the isotropic lattice; on the other hand, those on the anisotropic lattices give a better scaling. Moreover, on these two type of lattices the transverse parts are significantly suppressed in the infrared region and have a turnover at about 500 [MeV]. The high resolution to the temporal direction due to the anisotropy yields small discretization errors for the time-time gluon propagators, which also show an infrared enhancement as expected in the Gribov-Zwanziger confinement scenario.

Structure-property modeling and testing of transport layers for PEM fuel cells and water electrolysis cells
Creators: name: Nouri Khorasani, Amin
Publisher: name: University of British Columbia
Year: 2019

description: Widespread application of polymer electrolyte membrane fuel cells (PEMFC) and water electrolyzers (PEMWE) in renewable energy systems depend on their performance in high current density conditions. For both applications, transport of species to/from the oxygen electrode is crucial to the system operation. Recent in-situ imaging of both PEMFC and PEMWE systems have shown that the product material accumulates at the interface of the oxygen electrode with the adjacent porous transport layer (PTL), and negatively affects the performance. This interface is therefore worth scrutinizing in terms of mass transport and electrostatics. In this thesis, I investigated how the structural and electrostatic properties of the catalyst layer and the PTL in each system leads to the electrochemical performance of the system. For a PEMWE cell, I modeled the bubble nucleation, growth and stability inside a PTL pore. Then, I analyzed the performance stability of the PEMWE in a diagnostic cell. The results show the distribution of electrolytic bubbles lifetime and directly address their performance impact for the first time. For a PEMFC, I investigated two interfaces at the fuel cell catalyst layer and PTL to find out how the properties of the interface affect the distribution of species at the interface. For a promising PTL candidate material, I investigated how engineering the pore and particle sizes could maximize the cathode catalyst layer (CCL) utilization. I modeled how liquid water pressure build-up should be balanced with the distance from the PTL interstitial pores to allow for the liquid water to diffuse out of the CCL. The developed models can be used as applied material development tools with respect to the transport. In the catalyst layer, I investigated how the oxidation state of Pt affects the local distribution of H⁺ at the Pt-O-H₂O-H⁺ interface using classical molecular dynamics. The results showed for the first time that classical double layer theories do not properly address the effect of surface oxide dipoles on the ion interactions at the charged interface. The results from my thesis can guide the material design for the transport layers in PEMFC and PEMWE applications that improve the two-phase transport and efficiency.
