Targeted therapy in low-grade serous ovarian carcinoma : characterization of MEK inhibitor response in novel patient-derived cell lines
Creators: name: Dawson, Amy
Publisher: name: University of British Columbia
Year: 2017

description: Low-grade serous ovarian carcinoma, or LGSOC, predominantly occurs in pre- menopausal women at lower frequency than the more common high-grade serous ovarian carcinoma. It tends to harbour few, but distinct, mutations, with a significant proportion of RAS oncogene mutations. Aberrations of the RAS-MAPK signaling pathway in LGSOC have led to the initiation of several clinical trials of MEK inhibitors in this disease. Due to the relative rarity of LGSOC, few representative model systems are available. Accordingly, there has been a lack of preclinical investigational drug testing in this disease. In this study, 11 histotype-specific cell lines have been derived and molecularly characterized in order to further elucidate the molecular biology of the disease, and serve as an important platform to test novel therapeutics in LGSOC. The most common missense mutations by HotSpot mutational profiling analysis were oncogenic KRAS/NRAS mutations, and varying levels of copy number aberration were seen. All cell lines were uniquely identifiable by short-tandem repeat analysis, with the exception of two patient-paired cell lines. The phenotypic and molecular responses to the 4 MEK inhibitors (MEKi) trametinib, selumetinib, refametinib, and binimetinib have been characterized in selected LGSOC cell lines through IC50 analysis, proliferation, viability, and apoptosis assays, and on-target drug effects by Western blot. Of the 4 MEKi, trametinib exhibited the best anti-proliferative effects and inhibition of MEK kinase activity. Biological and on-target data from two of the cell lines reveals an exquisite sensitivity to MEK inhibition. Reverse-phase protein array and quantitative mass spectrometry global proteomic analysis on control and MEKi-treated LGSOC cell lines was performed in order to examine basal proteomic differences between MEKi-sensitive and resistant LGSOC cell lines and gather data for examining proteomic changes upon MEKi treatment. Three significantly differentially expressed protein candidates (PKCα, EGFR, and Smac/DIABLO were identified between sensitive and resistant cell lines under control and MEKi treatment conditions by both proteomic platforms. Results from therapeutic testing in these pathologically reviewed, histotype- specific LGSOC models allow for a comparison of the overall efficacies of the 4 MEKi, characterization of drug sensitivity in novel cell lines, and identification of potential functional markers of MEKi response.

description: A review of solar cycle prediction methods and their performance is given, including forecasts for cycle 24 and focusing on aspects of the solar cycle prediction problem that have a bearing on dynamo theory. The scope of the review is further restricted to the issue of predicting the amplitude (and optionally the epoch) of an upcoming solar maximum no later than right after the start of the given cycle. Prediction methods form three main groups. Precursor methods rely on the value of some measure of solar activity or magnetism at a specified time to predict the amplitude of the following solar maximum. Their implicit assumption is that each numbered solar cycle is a consistent unit in itself, while solar activity seems to consist of a series of much less tightly intercorrelated individual cycles. Extrapolation methods, in contrast, are based on the premise that the physical process giving rise to the sunspot number record is statistically homogeneous, i.e., the mathematical regularities underlying its variations are the same at any point of time, and therefore it lends itself to analysis and forecasting by time series methods. Finally, instead of an analysis of observational data alone, model based predictions use physically (more or less) consistent dynamo models in their attempts to predict solar activity. In their overall performance precursor methods have clearly been superior to extrapolation methods. Nevertheless, some extrapolation methods may still be worth further study. Model based forecasts have not yet have had a chance to prove their skills. One method that has yielded predictions consistently in the right range during the past few solar cycles is that of K. Schatten et al., whose approach is mainly based on the polar field precursor. The incipient cycle 24 will probably mark the end of the Modern Maximum, with the Sun switching to a state of less strong activity.

description: We operate an on-demand source of single electrons in high perpendicular magnetic fields up to 30T, corresponding to a filling factor below 1/3. The device extracts and emits single charges at a tunable energy from and to a two-dimensional electron gas, brought into well defined integer and fractional quantum Hall (QH) states. It can therefore be used for sensitive electrical transport studies, e.g. of excitations and relaxation processes in QH edge states.

description: I present recent results from jets and jet-like correlation measurements from STAR. The pp data are compared to those from Au-Au collisions to attempt to infer information on the medium produced and how hard scattered partons interact with this matter. Results from d-Au events are utilized to investigate the magnitude of cold nuclear matter effects on hard scatterings. The evolution of the underlying event from pp to d-Au collisions is studied. In heavy-ion collisions, background fluctuations are the major source of systematic uncertainties in jet measurements. Detailed studies are therefore being made of these fluctuations and recent progress in our understanding is reported. Jet and jet-hadron correlations results are presented and give clear indications that partonic fragmentation at RHIC is highly modified in the presence of a strongly coupled coloured medium, resulting in a significant broadening and softening of the jet fragments correlation. Finally di-hadron correlations utilizing identified particles as triggers indicate that the "ridge" is stronger for p+K than for pi but that the near-side peak per-trigger yield remains unaltered from d-Au to Au-Au collisions.

description: The optical conductivity of graphite in quantizing magnetic fields is analytically evaluated for frequencies in the range of 10--300 meV, where the electron relaxation processes can be neglected and the low-energy excitations at the "Dirac lines" are more essential. The conductivity peaks are explained in terms of the electron transitions in graphite. Conductivity calculated per one graphite layer tends on average to the universal conductivity of graphene while the frequency is larger than the Landau spacing. The (semi)metal-insulator transformation is possible under doping in high magnetic fields.

The gap distribution is strongly anisotropic, with Delta_2 predominantly seen when scanning across unit-cell steps on the (001) sample surface. The spectra are well-fitted by an anisotropic two-band BCS s-wave gap function. Our spectroscopic data are confirmed by electronic heat capacity measurements which also provide evidence for a twin-gap scenario.

description: The microwave properties of a crystalline sapphire dielectric whispering gallery mode resonator have been measured at very low excitation strength (E/hf=1) and low temperatures (T = 30 mK). The measurements were sensitive enough to observe saturation due to a highly detuned electron spin resonance, which limited the loss tangent of the material to about 2e-8 measured at 13.868 and 13.259 GHz. Small power dependent frequency shifts were also measured which correspond to an added magnetic susceptibility of order 1e-9. This work shows that quantum limited microwave resonators with Q-factors > 1e8 are possible with the implementation of a sapphire whispering gallery mode system.
The local political economy of conditional cash transfers in Brazil
Creators: name: Frey, Anderson
Publisher: name: University of British Columbia
Year: 2016

description: Conditional cash transfers (CCT) are currently one of the most popular poverty reduction policies worldwide. Nevertheless, there is still limited evidence of their impact on the local political dynamics of developing nations plagued by corruption, clientelism, and vote buying. This thesis studies this issue using data from Brazil's Bolsa Família, the largest CCT program in the world. Abstract Chapter 2 proposes a theoretical mechanism to illustrate how a CCT program could affect local politics in such institutional setting, when local politicians cannot manipulate program eligibility. In a nutshell, when mayors are able to buy votes by diverting public resources into private payments to swing voters, a CCT program works as an income shock that reduces the voter's marginal utility coming from vote buying. Abstract Chapter 3 uses data from Brazil's Bolsa Família to test the theoretical predictions from the first Chapter. It shows that, when transfers are shielded from the influence of political intermediaries, they trigger a reduction in incumbency advantage, an increase in both political competition and the quality of candidates, and a reduction in the support for high-clientelism parties. Transfers also lead incumbents to shift spending toward redistributive health and education services. These results are estimated with a nonparametric multivariate regression discontinuity design. Abstract Despite of the improvements brought out by the CCT program, when politicians can control access to the program, some of these political impacts might be negative in the short-term. Chapter 4 tells this other side of the story: what happens when politicians are able to manipulate program enrollment. Using administrative data from the Bolsa Família registry, and a regression discontinuity design in close elections, this Chapter shows that mayors with reelection incentives are more likely to promote income underreporting fraud by households, for the purpose of eligibility to CCT. This fraud is rewarded by voters, as corrupt mayors have a higher reelection probability. Finally, the Chapter also shows the need for disciplining devices to reduce this type of corruption. A higher risk of audits by the federal government is shown to drastically reduce the effects of reelection incentives on fraud.

We verify the predicted metric by computing the leading weak coupling instanton contribution to the four fermion correlation using standard field theory techniques, and demonstrate perfect agreement. We also demonstrate how previously known three dimensional quantities can be recovered in appropriate small radius limit, and provide a simple geometric picture from brane construction.

HIV/STI prevention, unmet health needs, and work stress among im/migrant sex workers in Metro Vancouver
Creators: name: Sou, Julie Chong-Yee
Publisher: name: University of British Columbia
Year: 2016

description: Background: Im/migrant women often face barriers to conventional labour markets in destination countries, and are disproportionately represented in precarious employment arrangements, including sex work. Apart from sexual health, research examining broader health concerns of im/migrant sex workers (SWs) remains scarce. This thesis sought to investigate the relationship between im/migration experiences and (1) inconsistent condom use with clients, (2) unmet health needs, and (3) dimensions of work stress among SWs. Methods: This thesis utilized data from “An Evaluation of Sex Workers Health Access” (AESHA), a community-based prospective cohort of SWs in Metro Vancouver. Bivariate and multivariable logistic regression using generalized estimating equations (GEE) were used to model correlates of inconsistent condom use among im/migrant SWs only (Objective 1) and unmet health needs among all SWs (Objective 2). Multivariable confounder models using linear regression with GEE were developed to examine independent relationships between im/migration experience and dimensions of work stress (Objective 3). Results: In Objective 1, multivariable GEE analysis conducted among 182 im/migrant SWs enrolled in AESHA from January 2010 and February 2013 revealed that difficulty accessing condoms was the strongest predictor of inconsistent condom use (Objective 1). In Objective 2, among 742 im/migrant and Canadian-born SWs enrolled from January 2010 to February 2014, multivariable GEE analysis found that recent and long-term im/migration, police harassment and arrest, and lifetime abuse/trauma were associated with greater unmet health needs. In Objective 3, among 545 SWs enrolled from January 2010 to September 2014, multivariable confounder GEE modeling revealed that recent and long-term im/migrant SWs faced decreased work stress related to job demands compared to their Canadian-born counterparts, after adjustment for key confounders. Conclusions: Findings suggest that im/migration experience is a key driver of HIV/STI prevention, healthcare access, and work stress among SWs. Importantly, im/migration experiences intersect with other structural factors – working conditions, violence, policing, sex work criminalization– to shape the health and safety of im/migrant SWs. Culturally appropriate, low-barrier health and support services should be made accessible to im/migrant SWs. Sex work decriminalization along with supporting collectivization efforts within the workplace are also recommended to improve working conditions, health, and human rights for im/migrant SWs.

description: The potential of combining Adaptive Optics (AO) and Lucky Imaging (LI) to achieve high precision astrometry and differential photometry in the optical is investigated by conducting observations of the close 0\farcs1 brown dwarf binary GJ569Bab. We took 50000 $I$-band images with our LI instrument FastCam attached to NAOMI, the 4.2-m William Herschel Telescope (WHT) AO facility. In order to extract the most of the astrometry and photometry of the GJ569Bab system we have resorted to a PSF fitting technique using the primary star GJ569A as a suitable PSF reference which exhibits an $I$-band magnitude of $7.78\pm0.03$. The AO+LI observations at WHT were able to resolve the binary system GJ569Bab located at $4\farcs 92 \pm 0\farcs05$ from GJ569A. We measure a separation of $98.4 \pm 1.1$ mas and $I$-band magnitudes of $13.86 \pm 0.03$ and $14.48 \pm 0.03$ and $I-J$ colors of 2.72$\pm$0.08 and 2.83$\pm$0.08 for the Ba and Bb components, respectively. Our study rules out the presence of any other companion to GJ569A down to magnitude I$\sim$ 17 at distances larger than 1\arcsec. The $I-J$ colors measured are consistent with M8.5-M9 spectral types for the Ba and Bb components. The available dynamical, photometric and spectroscopic data are consistent with a binary system with Ba being slightly (10-20%) more massive than Bb. We obtain new orbital parameters which are in good agreement with those in the literature.

description: The d.c. magnetization and magnetic relaxation studies of the calcium doped samples, Y0.95Ca0.05BaCo2O5.5 and YBa0.95Ca0.05Co2O5.5, show the existence of a magnetic glass like behaviour in the family of cobaltites for the first time. Our investigations reveal glass-like arrest of kinetics at low temperature which prevents the system from reaching its magnetic ground state. We show that the low temperature state of these calcium doped phases, which consists of coexisting antiferromagnetic and ferro (or ferri) magnetic phase fractions, can be tuned in a number of ways. Our observations establish that the low temperature state of this oxide is not in thermal equilibrium. The glassy state is formed with the assistance of an external magnetic field, which makes it distinctly different from the more well known metastable state, the spin glass state. The cooling field can tune the fractions of the coexisting phases, and the glass-like state formed at low temperature can also be devitrified by warming the sample. The role of Ca doping in the appearance of these phenomena is discussed in terms of phase separation, involving Co3+ disproportionation into Co4+ ferromagnetic clusters and Co2+ antiferromagnetic clusters.

description: We revise the use of 8-dimensional conformal, complex (Cartan) domains as a base for the construction of conformally invariant quantum (field) theory, either as phase or configuration spaces. We follow a gauge-invariant Lagrangian approach (of nonlinear sigma-model type) and use a generalized Dirac method for the quantization of constrained systems, which resembles in some aspects the standard approach to quantizing coadjoint orbits of a group G. Physical wave functions, Haar measures, orthonormal basis and reproducing (Bergman) kernels are explicitly calculated in and holomorphic picture in these Cartan domains for both scalar and spinning quantum particles. Similarities and differences with other results in the literature are also discussed and an extension of Schwinger's Master Theorem is commented in connection with closure relations. An adaptation of the Born's Reciprocity Principle (BRP) to the conformal relativity, the replacement of space-time by the 8-dimensional conformal domain at short distances and the existence of a maximal acceleration are also put forward.

description: Targeting at the development of an accurate and efficient dose calculation engine for online adaptive radiotherapy, we have implemented a finite size pencil beam (FSPB) algorithm with a 3D-density correction method on GPU. This new GPU-based dose engine is built on our previously published ultrafast FSPB computational framework [Gu et al. Phys. Med. Biol. 54 6287-97, 2009]. Dosimetric evaluations against Monte Carlo dose calculations are conducted on 10 IMRT treatment plans (5 head-and-neck cases and 5 lung cases). For all cases, there is improvement with the 3D-density correction over the conventional FSPB algorithm and for most cases the improvement is significant. Regarding the efficiency, because of the appropriate arrangement of memory access and the usage of GPU intrinsic functions, the dose calculation for an IMRT plan can be accomplished well within 1 second (except for one case) with this new GPU-based FSPB algorithm. Compared to the previous GPU-based FSPB algorithm without 3D-density correction, this new algorithm, though slightly sacrificing the computational efficiency (~5-15% lower), has significantly improved the dose calculation accuracy, making it more suitable for online IMRT replanning.

description: Current experimental data on the neutrino parameters is in good agreement with tribimaximal mixing and may indicate the presence of an underlying family symmetry. For 76 flavor groups, we perform a systematic scan for models: The particle content is that of the Standard Model plus up to three flavon fields, and the effective Lagrangian contains all terms of mass dimension <=6. We find that 44 groups can accommodate models that are consistent with experiment at 3 sigma, and 38 groups can have models that are tribimaximal. For one particular group, we look at correlations between the mixing angles and make a prediction for theta13 that will be testable in the near future. We present the details of a model with theta12=33.9, theta23=40.9, theta13=5.1 to show that the recent tentative hints of a non-zero theta13 can easily be accommodated. The smallest group for which we find tribimaximal mixing is T7. We argue that T7 and T13 are as suited to produce tribimaximal mixing as A4 and should therefore be considered on equal footing. In the appendices, we present some new mathematical methods and results that may prove useful for future model building efforts.

description: In this paper we discuss various correlations measured by the concurrence (C), classical correlation (CC), quantum discord (QD), and geometric measure of discord (GMD) in a two-qubit Heisenberg XXZ spin chain in the presence of external magnetic field and Dzyaloshinskii-Moriya (DM) anisotropic antisymmetric interaction. Based on the analytically derived expressions for the correlations for the cases of thermal equilibrium and the inclusion of intrinsic decoherence, we discuss and compare the effects of various system parameters on the correlations in different cases. The results show that the anisotropy Jz is considerably crucial for the correlations in thermal equilibrium at zero temperature limit but ineffective under the consideration of the intrinsic decoherence, and these quantities decrease as temperature T rises on the whole. Besides, J turned out to be constructive, but B be detrimental in the manipulation and control of various quantities both in thermal equilibrium and under the intrinsic decoherence which can be avoided by tuning other system parameters, while D is constructive in thermal equilibrium, but destructive in the case of intrinsic decoherence in general. In addition, for the initial state $|Ψ_1(0) > = \frac{1}{\sqrt{2}} (|01 > + |10 >)$, all the correlations except the CC, exhibit a damping oscillation to a stable value larger than zero following the time, while for the initial state $|Ψ_2(0) > = \frac{1}{\sqrt{2}} (|00 > + |11 >)$, all the correlations monotonously decrease, but CC still remains maximum. Moreover, there is not a definite ordering of these quantities in thermal equilibrium, whereas there is a descending order of the CC, C, GMD and QD under the intrinsic decoherence with a nonnull B when the initial state is $|Ψ_2(0) >$.

description: Infrared-Faint Radio Sources (IFRS) are objects which are strong at radio wavelengths but undetected in sensitive Spitzer observations at infrared wavelengths. Their nature is uncertain and most have not yet been associated with any known astrophysical object. One possibility is that they are radio pulsars. To test this hypothesis we undertook observations of 16 of these sources with the Parkes Radio Telescope. Our results limit the radio emission to a pulsed flux density of less than 0.21 mJy (assuming a 50% duty cycle). This is well below the flux density of the IFRS. We therefore conclude that these IFRS are not radio pulsars.

Strategic localization : China's climate governance (2007-2016)
Creators: name: Wang, Juan
Publisher: name: University of British Columbia
Year: 2016

description: As the world’s largest GHG emitter, China’s climate governance no doubt matters for the future of global climate governance. Since 2007, China has improved its domestic climate governance through progressive policy measures and institutional building, at both national and local levels. In recent years, China has also been proactive in the multilateral and bilateral climate negotiations. Under the UNFCCC framework, China’s contribution to the success of 2015 Paris Agreement negotiation is undeniable. Prior to the 2016 G20 Hangzhou summit, China announced its ratification of the Paris agreement and further placed more focus on climate issues in Hangzhou summit. Bilaterally, the China-US Joint Presidential Statement on Climate Change in 2014 and 2015 showcases China’s political commitment to address climate change. Acknowledging China’s active climate actions, my research question asks: how do we explain China’s progressive climate governance in recent years? What are the driving forces behind China’s climate actions? The theory of norm localization proposed by Dr. Amitav Acharya stresses the agency role of local actors in norm diffusion, which opens research space for investigating the causal relationships between China’s domestic political economy and its progressive climate actions in recent years. This thesis argues that, China’s progressive climate governance can be explained by its strategic localization of climate change based on its need of energy security and economic transition. China has strategically utilized climate change as a normative platform to facilitate and legitimize its comprehensive transformation into low-carbon economy. In this process, the central governmental agencies play a dominant role in framing and merging climate governance with China’s new development agendas. Overall, behind the Chinese philosophy, climate governance is what China should do, but China takes actions in a strategic way to align with its national interests, politically and economically.

Top Quark Amplitudes with an Anomalous Magnetic Moment

description: The anomalous magnetic moment of the top quark may be measured during the first run of the LHC at 7 TeV. For these measurements, it will be useful to have available tree amplitudes with ttbar and arbitrarily many photons and gluons, including both QED and color anomalous magnetic moments. In this paper, we present a method for computing these amplitudes using the Britto-Cachazo-Feng-Witten (BCFW) recursion formula. Because we deal with an effective theory with higher-dimension couplings, there are roadblocks to a direct computation with the BCFW method. We evade these by using an auxiliary scalar theory to compute a subset of the amplitudes.

Violation of the geometric scaling behaviour of the amplitude for running QCD coupling in the saturation region
Creators: name: Saez, Bastian Diaz

Year: 2011
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this paper we show that the intuitive guess that the geometric scaling behaviour should be violated in the case of the running QCD coupling, turns out to be correct. The scattering amplitude of the dipole with the size $r$ depends on new dimensional scale: $Λ_{QCD}$, even at large values $Y = \ln(1/x)$ and $l\,=\, \ln\Lb \as\Lb r^2\Rb/\as\Lb 1/Q^2_s\Rb\Rb$. However, in this region we found a new scaling behaviour: the amplitude is a function of $ζ= Y\,l$. We state that only in the vicinity of the saturation scale $Q_s$ ($\as(Q^2_s)\,\ln \Lb r^2 Q^2_s\Rb\,\leq \, 1$), the amplitude shows the geometric scaling behaviour. Based on these finding the geometric scaling behavior that has been seen experimentally, stems from either we have not probed the proton at HERA and the LHC deeply inside the saturation region or that there exists the mechanism of freezing of the QCD coupling constant at $r^2 \approx 1/Q^2_s$.

Subjects: Service Level Agreements
Risk
Decision Theory
expected utility maximization

description: This thesis presents an approach for service providers to select an SLA portfolio that minimizes the SLA violation risk. It considers constraints on expected profit and available resources. The problem is addressed by applying decision theory and risk measures, especially by adapting the concept of portfolio selection by Harry Markowitz and the semi-variance. In order to capture a decision maker's attitude towards risk, utility theory and the concept of risk aversion are used.

description: This work develops highly efficient algorithms for analyzing large images. Applications include object-based change detection and screening. The algorithms are 10-100 times as fast as existing software, sometimes even outperforming FGPA/GPU hardware, because they are designed to suit the computer architecture. This thesis describes the implementation details and the underlying algorithm engineering methodology, so that both may also be applied to other applications.
Experimental study of segregation mechanisms in bedload sediment transport
Creators: name: Dudill, Ashley Rebecca
Publisher: name: University of British Columbia
Year: 2016

description: This research focuses upon size segregation mechanisms in riverine bedload sediment transport. Simplified experiments with fine grain inputs to a mobile coarse bed in equilibrium were undertaken in a small, narrow flume using spherical glass beads. The experiments demonstrate the influence of the size ratio between the bed (Dc) and the input (Df) upon the channel response. Size ratios (Dc/Df) between 7.14 and 1.25 were tested, with a constant coarse feed rate, and a variety of fine feed rates. Previous work has documented an increase in sediment transport rates as a result of a fine grain input; the experiments presented herein identify boundaries within this behaviour. Kinetic sieving takes place in the mobile bed surface, with the finer sediment moving to the bottom of the bedload transport layer at the interface to the underlying quasi-static coarse bed. The behavior at this interface dictates how a channel responds to a fine sediment input. If, by spontaneous percolation, the fine sediment is able to infiltrate into the underlying quasi-static bed, the total transport increases and the bed degrades causing a reduction in the slope. However, if the fine sediment input rate exceeds the transport capacity or is geometrically unable to infiltrate into the underlying bed, it forms a quasi-static layer underneath the transport layer that inhibits entrainment from the underlying bed, resulting in aggradation and an increase in bed slope. A formal test of the reproducibility of the aforementioned results was undertaken in a different laboratory, with the same experimental procedure. Comparison of the qualitative results reveals that the same dominant processes occur. Consistent differences, however, were present between the quantitative results; likely a result of differences in the experimental arrangement. A final set of experiments assesses the differences and similarities between experiments undertaken with spherical glass beads and with natural materials to examine the complexities introduced due to particle shape. While the experiments with ideal materials reveal fundamental mechanisms associated with granular transport of mixed sizes, several key new phenomena are apparent in the experiments with natural materials, including changes in the infiltration potential and the emergence of bed structures.

description: An analysis of the work of Mira Fernandes on unitary theories is presented. First it is briefly mentioned the Portuguese scientific context of the 1920s. A short analysis of the extension of Riemann geometries to new generalized geometries with new affine connections, such as those of Weyl and Cartan, is given. Based on these new geometries, the unitary theories of the gravitational and electromagnetic fields, proposed by Weyl, Eddington, Einstein, and others are then explained. Finally, the book and one paper on connections and two papers on unitary theories, all written by Mira Fernandes, are analyzed and put in context.
