Developments in waveform tomography of land seismic data with applications in south-central British Columbia
Creators: name: Smithyman, Brendan Robert
Publisher: name: University of British Columbia
Year: 2013

description: Waveform tomography (WT) is an advanced class of seismic imaging methods that may be applied to generate detailed models of subsurface velocity and attenuation by analysis of recorded field seismograms. WT comprises two steps: 1) initial velocity model building by traveltime inversion (raytracing) and 2) full-waveform inversion to update the model of velocity based on analysis of refracted data waveforms. The nature of this method requires that the initial model and simulated survey parameters reproduce closely those used for the field data acquisition. The application of WT to on-land seismic data is challenged by the geometry irregularities inherent in crooked-line two-dimensional (2D) seismic data acquisition. This thesis develops two methodologies that permit the inversion of on-land crooked-line vibroseis multi-channel seismic (MCS) reflection data by traveltime tomography (TT) and subsequent viscoacoustic full-waveform inversion (FWI) to generate 2D cross sections of P-wave velocity. The first method uses 2.5D TT and applies a TT-derived static correction to enable the subsequent application of 2D FWI. The second method uses 2.5D or three-dimensional (3D) TT followed by 2.5D full-waveform inversion that models 3D survey geometry (a new development). These technical developments are motivated and tested by a multi-part case study, which analyses data from the 2008 Geoscience BC Nechako Basin seismic survey. Both the static-correction method and 2.5D FWI method are applied to a single acquisition line. The results are analysed and compared with the conclusion that 2.5D WT provides a superior result, but at additional computational cost. This cost is still significantly lower than that associated with 3D FWI. The 2.5D WT method is applied to three datasets from the 2008 survey, and TT alone is applied to a fourth. The resulting models constrain the positions and lithology of Eocene volcanic rock units, Cretaceous strata and Jurassic or earlier basement rocks in the Nechako-Chilcotin Plateau region of south-central British Columbia. These results are synthesized and interpreted in conjunction with colocated surficial-geology maps, exploration well logs and geophysical results by other workers. This interpretation enhances the specific knowledge of lithostratigraphy along these acquisition profiles and informs general geological and geophysical analyses of the region.

description: Consider a random sample in the max-domain of attraction of a multivariate extreme value distribution such that the dependence structure of the attractor belongs to a parametric model. A new estimator for the unknown parameter is defined as the value that minimizes the distance between a vector of weighted integrals of the tail dependence function and their empirical counterparts. The minimization problem has, with probability tending to one, a unique, global solution. The estimator is consistent and asymptotically normal. The spectral measures of the tail dependence models to which the method applies can be discrete or continuous. Examples demonstrate the applicability and the performance of the method.

description: Liquid scintillator detectors are widely used in modern neutrino studies. The unique optical properties of semiconducting nanocrystals, known as quantum dots, offer intriguing possibilities for improving standard liquid scintillator, especially when combined with new photodetection technology. Quantum dots also provide a means to dope scintillator with candidate isotopes for neutrinoless double beta decay searches. In this work, the first studies of the scintillation properties of quantum-dot-doped liquid scintillator using both UV light and radioactive sources are presented.

description: We investigate the zero-temperature phase diagram of interacting Bose gases in the presence of a simple cubic optical lattice, going beyond the regime where the mapping to the single-band Bose-Hubbard model is reliable. Our computational approach is a new hybrid quantum Monte Carlo method which combines algorithms used to simulate homogeneous quantum fluids in continuous space with those used for discrete lattice models of strongly correlated systems. We determine the critical interaction strength and optical lattice intensity where the superfluid-to-insulator transition takes place, considering also the regime of shallow optical lattices and strong inter-atomic interactions. The implications of our findings for the super-solid state of matter are discussed.

EPI-002 accelerates ligand dissociation from androgen receptor by disrupting N-terminus to C-terminus interaction
Creators: name: Ding, Rick
Publisher: name: University of British Columbia
Year: 2015

description: Constitutively active splice variants of androgen receptor (AR) lacking the ligand-binding domain (LBD) are linked to the development and progression of castration-resistant prostate cancer (CRPC). Recent studies suggest a constitutively active splice variant, ARv⁵⁶⁷es, is capable of interacting with full-length AR, stabilizing and enhancing its ligand-dependent activities despite castrate levels of circulating androgen. EPI-001, an AR antagonist targeting the Nterminus domain (NTD) prevents N-terminus to C-terminus (N/C) interaction of AR, which is essential for AR antiparallel dimer formation. The ligand-dependent N/C interactions slow the dissociation of ligand from the LBD. Here we examine the effect of EPI-002, the most potent stereoisomer of EPI-001, on ARv⁵⁶⁷es complexed with full-length AR and test the hypothesis that EPI-002 will cause ligand to dissociate more quickly because it blocks N/C interaction. The aim of this study is two-fold as we first examined the effects of ARv⁵⁶⁷es on the dissociation rate of the full-length receptor. Then, we examined the effect of EPI-002 on the ligand dissociation rate of full-length AR with and without the presence of ARv⁵⁶⁷es. We have demonstrated that EPI-002 did not affect binding affinity of wild-type full-length AR nor the time for it to reach binding equilibrium. EPI-002 accelerated the ligand dissociation rate of wild-type full-length AR possibly by disrupting N/C interaction. Co-expression of ectopic ARv567es and wild-type full-length AR at 50:50 ratios did not alter the ligand dissociation rate of wild-type full-length AR but attenuated the effect of EPI-002. However, EPI-002 had minimal effect on the ligand dissociation rate of endogenous AR in LNCaP prostate cancer cells, consistent with the lack of effect when AR has a mutation in the LBD (T877A) that enhances the N/C interaction and slows the ligand dissociation rate compared to the wild-type AR. Together these data begin to reveal 1) the unique mechanisms of splice variant ARv⁵⁶⁷es on the dissociation rate of full-length AR; and 2) the effect of an AR NTD inhibitor on the dissociation rate of full-length AR with and without the presence of splice variants.

description: We present a study of the mechanical power generated by both winds and jets across the black hole mass scale. We begin with the study of ionized X-ray winds and present a uniform analysis using Chandra grating spectra. The high quality grating spectra facilitate the characterization of the outflow velocity, ionization and column density of the absorbing gas. We find that the kinetic power of the winds scales with increasing bolometric luminosity as log(L_wind) \propto (1.58 \pm 0.07) log(L_Bol). This means that SMBH may be more efficient than stellar-mass black holes in launching winds. In addition, the simplicity of the scaling may suggest common driving mechanisms across the mass scale. For comparison, we next examine jet production, estimating jet power based on the energy required to inflate local bubbles. The jet relation is log(L_Jet)\propto (1.18\pm0.24) log(L_Bol). The energetics of the bubble associated with Cygnus X-1 are particularly difficult to determine, and the bubble could be a background SNR. If we exclude Cygnus X-1, then the jets follow a consistent relation to the winds within errors but with a higher normalization, log(L_Jet) \propto (1.34 \pm 0.50) log(L_Bol). The formal consistency in the wind and jet scaling relations suggests that a common launching mechanism may drive both flows; magnetic processes are viable possibilities. We also examine winds with especially high velocities, v > 0.01c. These ultra-fast outflows tend to resemble the jets more than the winds, indicating we may be observing a regime in which winds become jets. This study allows for the total power from black hole accretion, both mechanical and radiative, to be characterized in a simple manner and suggests a possible connection between winds and jets. Finally, we find at low Eddington fractions, the jet power is dominant, and at high Eddington fractions the wind power is dominant.

We also describe the applications of these estimates to the problem of quantum scattering. In the second part, we generalize some of the methods developed for the NLS by many authors to the case of Gross-Pitaevskii (GP) hierarchies. In particular, we prove both regular and interaction Morawetz identities for the GP hierarchy, which appear here for the first time in the literature.

description: We consider a set of non-linear interactions between dark matter and dark energy which comprises couplings proportional to products of (powers of) the energy densities of both dark components and of the total energy. We demonstrate that under such conditions the final state of the Universe may differ substantially from that of the standard LCDM model. In particular, the ratio of the energy densities of dark matter and dark energy may approach a stable finite value or oscillate about such a value. Stationary solutions of this type require a phantom-type "bare" equation of state of the dark energy which, however, does not lead to a big-rip singularity. A corresponding analytic solution for a particular case is shown to be consistent with the supernova type Ia (SNIa) data from the Union2 set. For a broader class of interactions, a dynamical system analysis classifies stationary points with emphasis on their potential relevance for the coincidence problem.

description: The distributions of inter-island gaps and captures zones for islands nucleated on a one-dimensional substrate during submonolayer deposition are considered using a novel retrospective view. This provides an alternative perspective on why scaling occurs in this continuously evolving system. Distributional fixed point equations for the gaps are derived both with and without a mean field approximation for nearest neighbour gap size correlation. Solutions to the equations show that correct consideration of fragmentation bias justifies the mean field approach which can be extended to provide closed-from equations for the capture zones. Our results compare favourably to Monte Carlo data for both point and extended islands using a range of critical island size $i=0,1,2,3$. We also find satisfactory agreement with theoretical models based on more traditional fragmentation theory approaches.

description: In recent years, environmental problems: climate change, desertification, loss of biodiversity, depletion of natural resources, increasing poverty, lack of fresh water, food, energy, people and countries Problems such as inequality between the two are proof that the current economic systems are not perfect. Global crises, climate change, air pollution, loss of flora and fauna, increasing demand for water and other natural resources deepen the current socio-economic problems of stability in both developed and developing countries. The image of the current world, irreparable environmental disasters and huge damage to the environment requires the need to transition to a "green economy". The world's leading countries have already started the transition to a green economy. They have realized that green economy is not a substitute for sustainable development but is a way to achieve sustainable development.

description: We present a fast computational method to efficiently screen enzyme activity. In the presented method, the effect of mutations on the barrier height of an enzyme-catalysed reaction can be computed within 24 hours on roughly 10 processors. The methodology is based on the PM6 and MOZYME methods as implemented in MOPAC2009, and is tested on the first step of the amide hydrolysis reaction catalyzed by Candida Antarctica lipase B (CalB) enzyme. The barrier heights are estimated using adiabatic mapping and are shown to give barrier heights to within 3kcal/mol of B3LYP/6-31G(d)//RHF/3-21G results for a small model system. Relatively strict convergence criteria (0.5kcal/(molÅ)), long NDDO cutoff distances within the MOZYME method (15Å) and single point evaluations using conventional PM6 are needed for reliable results. The generation of mutant structure and subsequent setup of the semiempirical calculations are automated so that the effect on barrier heights can be estimated for hundreds of mutants in a matter of weeks using high performance computing.

description: We show that spin S Heisenberg spin chains with an additional three-body interaction of the form (S_{i-1}S_{i})(S_{i}S_{i+1})+h.c. possess fully dimerized ground states if the ratio of the three-body interaction to the bilinear one is equal to 1/(4S(S+1)-2). This result generalizes the Majumdar-Ghosh point of the J_1-J_2 chain, to which the present model reduces for S=1/2. For S=1, we use the density matrix renormalization group method (DMRG) to show that the transition between the Haldane and the dimerized phases is continuous with central charge c=3/2. Finally, we show that such a three-body interaction appears naturally in a strong-coupling expansion of the Hubbard model, and we discuss the consequences for the dimerization of actual antiferromagnetic chains.

(Figs 123–124, 312)
 Species recognition. This species is similar to D. mississipiensis and D. conspicua, but D. mississippiensis has a non-spinulose concavity on the hind femur. This species differs from D. conspicua by the much less-developed hind coxal lobe (similar to those in D. mississippiensis) and the dorsal margin of the concavity. In D. conspicua, the dorsal margin of the concavity curves ventrally towards the ventral margin of the hind femur, whereas in D. sarriae this line extends basally in a nearly straight line. Additionally, in D. sarriae, the apex of the imbricate lobe is expanded dorsally and ventrally.

description: In this paper, we consider a simple network consisting of a source, a half-duplex decode-and-forward relay, and a destination. We propose a new relaying protocol employing adaptive link selection, i.e., in any given time slot, based on the channel state information of the source-relay and the relay-destination link a decision is made whether the source or the relay transmits. In order to avoid data loss at the relay, adaptive link selection requires the relay to be equipped with a buffer such that data can be queued until the relay-destination link is selected for transmission. We study both delay constrained and delay unconstrained transmission. For the delay unconstrained case, we characterize the optimal link selection policy, derive the corresponding throughput, and develop an optimal power allocation scheme. For the delay constrained case, we propose to starve the buffer of the relay by choosing the decision threshold of the link selection policy smaller than the optimal one and derive a corresponding upper bound on the average delay. Furthermore, we propose a modified link selection protocol which avoids buffer overflow by limiting the queue size. Our analytical and numerical results show that buffer-aided relaying with adaptive link selection achieves significant throughput gains compared to conventional relaying protocols with and without buffers where the relay employs a fixed schedule for reception and transmission.

Boundary conditions for SU(2) Yang-Mills on $AdS_4$

description: We consider SU(2) Yang-Mills theory on $AdS_4$ by imposing various boundary conditions, which correspond to non-trivial deformations of its boundary $CFT$. We obtain classical solutions of Yang-Mills fields up to the first subleading order correction by using small amplitude expansion of the gauge field without considering gravitational back reaction. We also consider SU(2) Yang-Mills instanton solution in $AdS_4$ bulk, and propose a boundary action. It turns out that the boundary theory is the Chern Simons theory with a non-local deformation which has the form similar to the Wilson line. In the limit of the deformation parameter $ρ\rightarrow \infty$, this non-local deformation is suppressed and the boundary theory becomes pure Chern Simons. For large but finite values of $ρ$, this non-local deformation can be treated perturbatively within the Chern-Simon theory.

description: We discuss chiral zero-rest-mass field equations on six-dimensional space-time from a twistorial point of view. Specifically, we present a detailed cohomological analysis, develop both Penrose and Penrose-Ward transforms, and analyse the corresponding contour integral formulae. We also give twistor space action principles. We then dimensionally reduce the twistor space of six-dimensional space-time to obtain twistor formulations of various theories in lower dimensions. Besides well-known twistor spaces, we also find a novel twistor space amongst these reductions, which turns out to be suitable for a twistorial description of self-dual strings. For these reduced twistor spaces, we explain the Penrose and Penrose-Ward transforms as well as contour integral formulae.

description: We discuss pseudoduality transformations in two dimensional conformally invariant classical sigma models, and extend our analysis to a given boundaries of world-sheet, which gives rise to an appropriate framework for the discussion of the pseudoduality between D-branes. We perform analysis using the Euclidean spacetime and show that structures on the target space can be transformed into pseudodual manifold identically. This map requires that torsions and curvatures related to individual spaces are the same when connections are riemannian. Boundary pseudoduality imposes locality condition.

description: We study the energy transfer performance in electrically and magnetically coupled mechanical nanoresonators. Using the resonant scattering theory, we show that magnetically coupled resonators can achieve the same energy transfer performance as for their electrically coupled counterparts, or even outperform them within the scale of interest. Magnetic and electric coupling are compared in the Nanotube Radio, a realistic example of a nano-scale mechanical resonator. The energy transfer performance is also discussed for a newly proposed bio-nanoresonator composed of a magnetosomes coated with a net of protein fibers.

Teacher empowerment and China's curriculum reform : to what extent do teachers feel empowered by Chinese curriculum reform? : a case study based on Dalian No. 24 Senior High School
Creators: name: Wang, Xiao
Publisher: name: University of British Columbia
Year: 2013

description: This study examines the enactment of teacher empowerment in Dalian No. 24 Senior High School within the context of the current Chinese Curriculum Reform Movement (CRM). A review of current Chinese and American literature on teacher empowerment was given to provide a background to better understand specific issues that impact teacher empowerment. Additionally, a qualitative case study on this leading Chinese high school is presented with the aim of raising awareness of teacher empowerment involving Chinese curricular reform. Data collection included a literature review, semi-structured open-ended interviews and surveys. Face-to-face interviews and questionnaire surveys were conducted at Dalian No. 24 Senior High School. Accordingly, this study aims to provide practical insights on issues affecting teacher empowerment as applicable to Dalian No. 24 Senior High School. Two additional purposes of the study are to build on the existing, but limited, research knowledge in this area and to provide avenues for future inquiry. Results from this study highlight the benefits of teacher empowerment, including increased performance and productivity, improved teacher morale, and increased knowledge of subject matter and pedagogy. At Dalian No. 24 Senior High School, three key issues were discovered: first, most of the teacher participants hold a positive attitude towards teacher empowerment and the latest National Curriculum Reform (NCR); second, this school holds a supportive environment to teacher empowerment and teachers’ professional development; and third, there are still drawbacks to implementing teacher empowerment and the changes required by the NCR that the teachers and the school need to address.

description: We solve the long-standing central spin problem for a general set of inhomogeneous bath couplings and a large class of initial bath states. We compute the time evolution of the coherence of a central spin coupled to a spin bath by resumming all orders of the time-convolutionless master equation, thus avoiding the need to assume weak coupling to the bath. The fully quantum, non-Markovian solution is obtained in the large-bath limit and is valid up to a timescale set by the largest coupling constant. Our result captures the full decoherence of an electron spin qubit coupled to a nuclear spin bath in a GaAs quantum dot for experimentally relevant parameters. In addition, our solution is quite compact and can readily be used to make quantitative predictions for the decoherence process and to guide the design of nuclear state preparation protocols.

The implications of dust for high-redshift protogalaxies and the formation of binary disks

description: Numerical simulations suggest that the first galaxies are formed in protogalactic halos with virial temperatures >= 10^4 K. It is likely that such halos are polluted with trace amounts of metals produced by the first generation of stars. The presence of dust can significantly change the chemistry and dynamics of early galaxies. In this article, we aim to assess the role of dust on the thermal and dynamical evolution of the first galaxies in the presence of a background UV flux, and its implications for the observability of Lyman alpha emitters and sub-mm sources. We have performed high resolution cosmological simulations using the adaptive mesh refinement code FLASH to accomplish this goal. We have developed a chemical network appropriate for these conditions and coupled it with the FLASH code. The main ingredients of our chemical model include the formation of molecules, a multi-level treatment of atomic hydrogen, line trapping of Lyman alpha photons and, photoionization and photodissociation processes in a UV background. We found that the formation of molecules (H_{2} and HD) is significantly enhanced in the presence of dust grains. The presence of a background UV flux strongly influences the formation of molecules by photodissociating them. We explore the evolution after a major merger, leading to the formation of a binary disk. These disks have gas masses of ~10^{7} M_sun at a redshift of 5.4. Each disk lies in a separate subhalo as a result of the merger event. The disks are supported by turbulent pressure due to the highly supersonic turbulence present in the halo. The presence of dust does not significantly reduce the Lyman alpha emission. The emission of Lyman alpha is extended and originates from the envelope of the halo due to line trapping effects. We also find that dust masses of 10^8 M_sun are required to observe the dust continuum emission from z 5 galaxies with ALMA.

The Link between Entropic Uncertainty and Nonlocality

description: Two of the most intriguing features of quantum physics are the uncertainty principle and the occurrence of nonlocal correlations. The uncertainty principle states that there exist pairs of incompatible measurements on quantum systems such that their outcomes cannot both be predicted. On the other hand, nonlocal correlations of measurement outcomes at different locations cannot be explained by classical physics, but appear in the presence of entanglement. Here, we show that these two fundamental quantum effects are quantitatively related. Namely, we provide an entropic uncertainty relation for the outcomes of two binary measurements, where the lower bound on the uncertainty is quantified in terms of the maximum Clauser-Horne-Shimony-Holt value that can be achieved with these measurements. We discuss applications of this uncertainty relation in quantum cryptography, in particular, to certify quantum sources using untrusted devices.

description: Recent measurements of resonance widths for low-energy neutron scattering off heavy nuclei show large deviations from the standard Porter-Thomas distribution. We propose a new resonance width distribution based on the random matrix theory for an open quantum system. Two methods of derivation lead to a single analytical expression; in the limit of vanishing continuum coupling, we recover the Porter-Thomas distribution. The result depends on the ratio of typical widths $Γ$ to the energy level spacing $D$ via the dimensionless parameter $κ=(πΓ/2D)$. The new distribution suppresses small widths and increases the probabilities of larger widths.
