description: The challenge in controlling stochastic systems in which low-probability events can set the system on catastrophic trajectories is to develop a robust ability to respond to such events without significantly compromising the optimality of the baseline control policy. This paper presents CelluDose, a stochastic simulation-trained deep reinforcement learning adaptive feedback control prototype for automated precision drug dosing targeting stochastic and heterogeneous cell proliferation. Drug resistance can emerge from random and variable mutations in targeted cell populations; in the absence of an appropriate dosing policy, emergent resistant subpopulations can proliferate and lead to treatment failure. Dynamic feedback dosage control holds promise in combatting this phenomenon, but the application of traditional control approaches to such systems is fraught with challenges due to the complexity of cell dynamics, uncertainty in model parameters, and the need in medical applications for a robust controller that can be trusted to properly handle unexpected outcomes. Here, training on a sample biological scenario identified single-drug and combination therapy policies that exhibit a 100% success rate at suppressing cell proliferation and responding to diverse system perturbations while establishing low-dose no-event baselines. These policies were found to be highly robust to variations in a key model parameter subject to significant uncertainty and unpredictable dynamical changes.

description: We prove that, in types $E_{6,7,8}^{(1)}$, $F_4^{(1)}$ and $E_6^{(2)}$, every Kirillov--Reshetikhin module associated with the node adjacent to the adjoint one (near adjoint node) has a crystal pseudobase, by applying the criterion introduced by Kang et.al. In order to apply the criterion, we need to prove some statements concerning values of a bilinear form. We achieve this by using the global bases of extremal weight modules.

description: What are the socioeconomic implications of the time allocation decisions made by low-income adolescents? The way adolescents allocate their time between schooling, labor and leisure has important implications for their education attainment, college aspirations, job opportunities and future earnings. This study focuses on adolescents and young adults in urban areas of Brazil that, due to household income constraints, family or peer pressures enter the labor market at an early age, stop studying, and/or start engaging into risky behaviors, such as drug use or sexual activities. The key policy question in this context is then: what incentives could prove an efficient tool to change the time allocation patterns and behaviors that make adolescents drop out of school, fall pregnant (or impregnate) or consume drugs? This dissertation uses data from the Young Agent Project (YAP) a Conditional Cash Transfer (CCT) Program targeting exclusively adolescents in Brazil to examine this issue. This program targets adolescents aged 15 to 17 and its goals are to improve the socioeconomic and educational outcomes of youth in Brazil. The research in the dissertation seeks to determine whether the program has indeed influenced or not the time allocation decisions of low-income youth in Brazil, thus improving their socioeconomic and educational outcomes. The research addresses this issue in three different levels of analysis: 1) whether the YAP has affected schooling outcomes, youth labor decisions and risky behaviors, by gender, ethnicity or region, 2) whether transferring cash directly to the adolescent is more efficient than transferring to the parents, on improving schooling, labor and risky behavior outcomes, and 3) Whether the number of hours per week dedicated to the YAP's after school program is a strong predictor of better outcomes. The data used is the 2006 Projeto Agente Jovem dataset, which is a matched non-experimental, with a treatment group and a constructed control group. This dataset is representative of the recipients of the YAP across regions, states, genders and racial composition, which was administered to 2,210 households with adolescents aged 16 to 20 at least one year after having finished the program. For the analysis, this study used econometric techniques such as Propensity Score Matching (Average Treatment Effect on the Treated, Nearest Neighbor with Replacement) and performed robustness checks with a sensitivity analysis by comparing the treatment effects obtained from linear regression and Inverse Probability of Treatment Weighting.

In the case of codimension one, the latter criterion establishes a relation with solutions of a system of nonlinear second-order PDEs. Some particular cases of this system were considered by Goursat in 1899.

description: It is commonly accepted that a parametric amplifier can simulate a phase-preserving linear amplifier regardless of how the latter is realized [Caves et al., Phys. Rev. A 86, 063802 (2012)]. If true, this reduces all phase-preserving linear amplifiers to a single familiar model. Here we disprove this claim by constructing two counterexamples. A detailed discussion of the physics of our counterexamples is provided. It is shown that a Heisenberg-picture analysis facilitates a microscopic explanation of the physics. This also resolves a question about the nature of amplifier-added noise in degenerate two-photon amplification.

description: This paper examines the uncovered interest parity hypothesis using the dollar-sterling exchange rate during the gold standard era. This period is interesting because the exchange rate was seasonal, because transactions costs were high, and because occasions when uncovered interest rate speculation did not occur can be identified. The paper shows UIP speculation frequently did not occur, that speculation occurred more in response to expected exchange rate changes than interest rate differentials, and that profitability varied systematically with interest rate differentials. The estimated UIP equations are substantially improved by distinguishing occasions when sterling was borrowed not lent.

description: The order of the post-Newtonian expansion needed, to extract in a reliable and accurate manner the fully general relativistic gravitational wave signal from inspiralling compact binaries, is explored. A class of approximate wave forms, called P-approximants, is constructed based on the following two inputs: (a) The introduction of two new energy-type and flux-type functions e(v) and f(v), respectively, (b) the systematic use of Pade approximation for constructing successive approximants of e(v) and f(v). The new P-approximants are not only more effectual (larger overlaps) and more faithful (smaller biases) than the standard Taylor approximants, but also converge faster and monotonically. The presently available O(v/c)^5-accurate post-Newtonian results can be used to construct P-approximate wave forms that provide overlaps with the exact wave form larger than 96.5% implying that more than 90% of potential events can be detected with the aid of P-approximants as opposed to a mere 10-15 % that would be detectable using standard post-Newtonian approximants.

description: Childhood glaucoma (CG) encompasses a heterogeneous group of genetic eye disorders that is responsible for approximately 5% of childhood blindness worldwide. Understanding the molecular aetiology is key to improving diagnosis, prognosis and unlocking the potential for optimising clinical management. In this study, we investigated 86 CG cases from 78 unrelated families of diverse ethnic backgrounds, recruited into the Genomics England 100,000 Genomes Project (GE100KGP) rare disease cohort, to improve the genetic diagnostic yield. Using the Genomics England/Genomic Medicine Centres (GE/GMC) diagnostic pipeline, 13 unrelated families were solved (13/78, 17%). Further interrogation using an expanded gene panel yielded a molecular diagnosis in 7 more unrelated families (7/78, 9%). This analysis effectively raises the total number of solved CG families in the GE100KGP to 26% (20/78 families). Twenty-five percent (5/20) of the solved families had primary congenital glaucoma (PCG), while 75% (15/20) had secondary CG; 53% of this group had non-acquired ocular anomalies (including iris hypoplasia, megalocornea, ectopia pupillae, retinal dystrophy, and refractive errors) and 47% had non-acquired systemic diseases such as cardiac abnormalities, hearing impairment, and developmental delay. CYP1B1 was the most frequently implicated gene, accounting for 55% (11/20) of the solved families. We identified two novel likely pathogenic variants in the TEK gene, in addition to one novel pathogenic copy number variant (CNV) in FOXC1. Variants that passed undetected in the GE100KGP diagnostic pipeline were likely due to limitations of the tiering process, the use of smaller gene panels during analysis, and the prioritisation of coding SNVs and indels over larger structural variants, CNVs, and non-coding variants.
Tau-Functions generating the Conservation Laws for Generalized Integrable Hierarchies of KdV and Affine-Toda type

description: For a class of generalized integrable hierarchies associated with affine (twisted or untwisted) Kac-Moody algebras, an explicit representation of their local conserved densities by means of a single scalar tau-function is deduced. This tau-function acts as a partition function for the conserved densities, which fits its potential interpretation as the effective action of some quantum system. The class consists of multi-component generalizations of the Drinfel'd-Sokolov and the two-dimensional affine Toda lattice hierarchies. The relationship between the former and the approach of Feigin, Frenkel and Enriquez to soliton equations of KdV and mKdV type is also discussed. These results considerably simplify the calculation of the conserved charges carried by the soliton solutions to the equations of the hierarchy, which is important to establish their interpretation as particles. By way of illustration, we calculate the charges carried by a set of constrained KP solitons recently constructed.

description: In this note we report the results of our study of a 1D integrable spin chain whose critical behaviour is governed by a CFT possessing a continuous spectrum of scaling dimensions. It is argued that the computation of the density of Bethe states of the continuous theory can be reduced to the calculation of the connection coefficients for a certain class of differential equations whose monodromy properties are similar to those of the conventional confluent hypergeometric equation. The finite size corrections to the scaling are also discussed.

Twists in Topological Codes
Creators: name: Bombin, Hector
Publisher: name: The University of British Columbia
Year: 2016

description: There exists a close relationship between topological quantum error-correcting codes and topological order in condensed matter systems. Indeed, a topological stabilizer code can be regarded as the ground state of a suitable Hamiltonian model, so that "wrong" syndromes correspond to excitations. These excitations are anyons, quasiparticles that carry a topological charge and exhibit exotic statistics. Anyon models can be symmetric under some permutations of their topological charges. One can then conceive topological defects that, under monodromy, transform anyons according to a symmetry. We call these defects twists. Twists give rise to new topological degrees of freedom in the ground state, useful as a quantum memory. Moreover, twists can be braided to perform topologically protected gates on these topological qubits. Thus, twists provide a new way to encode and compute with topological codes through code deformations. Because the properties of twists depend on the anyon model, codes with different anyon content give rise to different computational capabilities. E.g., in the well-known toric code a process where suitable twists are braided and fused has the same outcome as if they were Ising anyons. These are non-abelian anyons: braiding produces non-trivial gates on encoded qubits.

description: The simplest explanation for early time acceleration (inflation) and the late time acceleration indicated by recent data is that they have a common origin. We investigate another generic cosmological implication of this possiblity, that the baryon asymmetry of the universe may be generated in such models. We identify several novel features of baryogenesis in such a universe, in which a rolling scalar field is always part of the cosmological energy budget. We also propose a concrete mechanism by which the baryon asymmetry of the universe may be generated in this context. We analyze the generic properties of and constraints on these cosmologies, and then demonstrate explicitly how a complete cosmology may develop in some specific classes of models.

description: Tree-level scattering amplitudes in Yang-Mills theory satisfy a recursion relation due to Berends and Giele which yields e.g. the famous Parke-Taylor formula for MHV amplitudes. We show that the origin of this recursion relation becomes clear in the BV formalism, which encodes a field theory in an $L_\infty$-algebra. The recursion relation is obtained in the transition to a smallest representative in the quasi-isomorphism class of that $L_\infty$-algebra, known as a minimal model. In fact, the quasi-isomorphism contains all the information about the scattering theory. As we explain, the computation of such a minimal model is readily performed in any BV quantisable theory, which, in turn, produces recursion relations for its tree-level scattering amplitudes.

Teacher turnover

description: Teachers are central to improving education quality and student learning. Yet, it is common that education systems short-pay teachers. Linking the occupational choice literature, this dissertation raises concern regarding potentially large adverse effects of holding teacher wages back from broader market levels, in terms of declining teacher aptitude and reduced student learning. Using a four-part analysis, I examine and contextualize theoretical stipulations using the case of Chinese teachers. Firstly, in Part I, I establish the causal link between teachers’ human capital level and student learning outcomes, by employing student fixed-effect models to relate differences in teachers across subjects to variations in student test scores. I find statistically significant impacts of teachers holding advanced tertiary degrees on improving student learning, at 0.033 standard deviations or adding about 1 additional month of learning over a typical 9-month academic year. Secondly, in Part II, I document relative pay gaps between teachers and comparable workers using Mincer earnings function. Between 1988 and 2013, I find sharp shifts in the relative wage attractiveness in the teaching sector, such that teachers’ mean wage levels experienced 24 percentage-points reversal, at 11 percent below the private sector levels in 2013. Also, returns to holding advanced tertiary degrees in teaching is about 11 to 15 percent less than that of the private sector in years 2007, 2008, and 2013, while this difference was statistically indistinguishable in the pre-2007 period. Thirdly, in Part III, I estimate the probability of entry to teaching by different human capital traits, and find declining trends for more educated individuals overall. In 2007 and 2013, new labor market entrants with advanced tertiary degrees are 4.7 and 5.8 percentage-points less likely than comparable workers in older cohorts to choose teaching. Similar patterns continue to hold when I use alternative human capital and skills proxies. Fourthly, in Part IV, using a national representative panel dataset containing 211 matched teachers, I track career destinations and relate it to opportunity wages and non-pecuniary outcomes. In general, I find that teacher turnover rates are high at about 35 percent, half of which are exits from the education sector entirely; there also exist positive associations between opportunity wage levels and turnover decisions, but there is no evidence of non-pecuniary gains from turnovers.

description: This dissertation draws on a wide range of sources (including motion pictures, film journals, and essays) in order to analyze the debate over the social and aesthetic role of cinema that took place in France from 1909 to 1930. During this period, as the new medium became the most popular form of entertainment, moralists of all political persuasions began to worry that cinematic representations of illicit acts could provoke social unrest. In response, four groups usually considered antagonistic -- republicans, Catholics, Communists, and the first film avant-garde known as the Impressionists -- set out to redefine cinema by focusing particularly on shaping film viewers. To do so, these movements adopted similar strategies: they organized lectures and film clubs, published a variety of periodicals, commissioned films for specific causes, and screened commercial motion pictures deemed compatible with their goals. Tracing the history of such projects, I argue that they insisted on educating spectators both through and about cinema. Indeed, each movement sought to teach spectators of all backgrounds how to understand the new medium of cinema while also supporting specific films with particular aesthetic and political goals. Despite their different interests, the Impressionists, republicans, Catholics, and Communists all aimed to create communities of viewers that would learn a certain way of decoding motion pictures. My main focus is on how each group defined its ideal spectator, on the tensions manifested within their pedagogical projects, and on the ways in which these projects intersected. Ultimately, the history uncovered here sheds new light on key questions about cinema's impact that marked the twentieth century.

description: Neutrinos of astrophysical origin could be detected through the electromagnetic radiation of the particle showers induced in the atmosphere by their interaction in the Earth. This applies in particular for tau neutrinos of energies $E>10^{16}$eV following Earth-skimming trajectories. The $\sim1^{\circ}$ beaming of the radio emission in the forward direction however implies that the radio signal will likely fly above a detector deployed over a flat site and would therefore not be detected. We study here how a non-flat detector topography can improve the detection probability of these neutrino-induced air showers. We do this by computing with three distinct tools the neutrino detection efficiency for a radio array deployed over a toy-model mountainous terrain, also taking into account experimental and topographic constraints. We show in particular that ground topographies inclined by few degrees only induce detection efficiencies typically three times larger than those obtained for flat areas for favorable trajectories. We conclude that the topography of the area where the detector is deployed will be a key factor for an experiment like GRAND.

description: Objectives: To evaluate the relationship between high-heeled shoes of varied heel height and bladder neck elevation in women. Methods: A cross-sectional, exploratory design was applied. Twenty-three continent 18–49-year-old women performed pelvic floor muscle (PFM) contractions while standing in high-heeled shoes of varied heel height. Transabdominal ultrasound was used to evaluate bladder neck elevation in ventral-cranial direction from the resting position during maximum voluntary contraction (MVC) of pelvic floor muscles. Results: Significantly greater bladder neck elevation was demonstrated in neutral ankle position compared to the two- (0.27 [95% CI 0.14–0.39] p p Conclusion: Significantly lower bladder neck elevation in high-heeled conditions indicates that pelvic floor muscle contraction to elevate bladder neck might not be as strong while wearing high-heel shoes as it is while standing bare feet. Further studies with larger sample size are required to evaluate the possible relationship between varied heel height, bladder neck elevation, and urinary incontinence in women.

description: This study explored the educative impact of a music study abroad program, specifically, what role music plays in encounters between students from diverse cultural backgrounds, and how such programs can help shape the identity of a global citizen and lead to a more socially just global community. If programmatic efforts can be impactful, preparing young people for life in a more interdependent, complex, and fragile world, then how can such values be informed, fostered, and even stimulated by engaging in international music travel? How is “difference” experienced and rendered meaningful? This qualitative case study followed U.S. music and music education students on a trip to Malaysia where they collaborated with Malaysian peers in bamboo instrument-making as well as music-making in traditional Malay styles. Perspectives, commentary, and reflections of and by all participants were recorded and investigated. Pre-trip interviews were conducted two months prior to embarking on the international trip. During the program abroad over the course of three weeks, I interviewed four U.S. music students, five Malaysian music education students, and both a U.S. and Malay music professor. Additionally, a focus group was conducted with the Malay student-participants. This study posited two primary benefits to studying music abroad and then analyzed data that would illuminate to what degree these benefits were achieved. The first of these benefits is the well-known enhancement in broader experience and new knowledge that will inform students’ practice and musical life going forward. The second class of benefits has to do with building agency as global citizens, along with an appreciation of the entailed challenges. The interaction between visitors and residents, between students and a diverse cohort of educators, all begin to construct a sense of interconnectedness that goes far beyond the accumulation of musical knowledge. The findings substantiated the initial hypotheses and created new avenues of inquiry as well. One finding that went beyond the original scope of the study was that in reflecting on their experiences, participants began to build on a sense of global citizenship and a broadened civic consciousness. This in turn leads to investigations into the broader definition of education itself.

description: The standard approach to the numerical evolution of black hole data using the ADM formulation with maximal slicing and vanishing shift is extended to non-symmetric black hole data containing black holes with linear momentum and spin by using a time-independent conformal rescaling based on the puncture representation of the black holes. We give an example for a concrete three dimensional numerical implementation. The main result of the simulations is that this approach allows for the first time to evolve through a brief period of the merger phase of the black hole inspiral.

description: Multi-contrast images are commonly acquired together to maximize complementary diagnostic information, albeit at the expense of longer scan times. A time-efficient strategy to acquire high-quality multi-contrast images is to accelerate individual sequences and then reconstruct undersampled data with joint regularization terms that leverage common information across contrasts. However, these terms can cause features that are unique to a subset of contrasts to leak into the other contrasts. Such leakage-of-features may appear as artificial tissues, thereby misleading diagnosis. The goal of this study is to develop a compressive sensing method for multi-channel multi-contrast magnetic resonance imaging (MRI) that optimally utilizes shared information while preventing feature leakage. Joint regularization terms group sparsity and colour total variation are used to exploit common features across images while individual sparsity and total variation are also used to prevent leakage of distinct features across contrasts. The multi-channel multi-contrast reconstruction problem is solved via a fast algorithm based on Alternating Direction Method of Multipliers. The proposed method is compared against using only individual and only joint regularization terms in reconstruction. Comparisons were performed on single-channel simulated and multi-channel in-vivo datasets in terms of reconstruction quality and neuroradiologist reader scores. The proposed method demonstrates rapid convergence and improved image quality for both simulated and in-vivo datasets. Furthermore, while reconstructions that solely use joint regularization terms are prone to leakage-of-features, the proposed method reliably avoids leakage via simultaneous use of joint and individual terms, thereby holding great promise for clinical use.

description: The dying ReLU refers to the problem when ReLU neurons become inactive and only output 0 for any input. There are many empirical and heuristic explanations of why ReLU neurons die. However, little is known about its theoretical analysis. In this paper, we rigorously prove that a deep ReLU network will eventually die in probability as the depth goes to infinite. Several methods have been proposed to alleviate the dying ReLU. Perhaps, one of the simplest treatments is to modify the initialization procedure. One common way of initializing weights and biases uses symmetric probability distributions, which suffers from the dying ReLU. We thus propose a new initialization procedure, namely, a randomized asymmetric initialization. We prove that the new initialization can effectively prevent the dying ReLU. All parameters required for the new initialization are theoretically designed. Numerical examples are provided to demonstrate the effectiveness of the new initialization procedure.

description: In this article, we consider the Bayes and empirical Bayes problem of the current population mean of a finite population when the sample data is available from other similar (m-1) finite populations. We investigate a general class of linear estimators and obtain the optimal linear Bayes estimator of the finite population mean under a squared error loss function that considered the cost of sampling. The optimal linear Bayes estimator and the sample size are obtained as a function of the parameters of the prior distribution. The corresponding empirical Bayes estimates are obtained by replacing the unknown hyperparameters with their respective consistent estimates. A Monte Carlo study is conducted to evaluate the performance of the proposed empirical Bayes procedure.
Quantum algorithm for preparing thermal Gibbs states
Creators: name: Wocjan, Pawel
Publisher: name: The University of British Columbia
Year: 2016

description: We present a quantum algorithm for preparing thermal Gibbs states of interacting quantum systems. This algorithm is based on Grover’s technique for quantum state engineering, and its running time is dominated by the factor sqrt{D/Z}, where D and Z_beta denote the dimension of the quantum system and its partition function at inverse temperature beta, respectively. We discuss the differences between this algorithm and quantum Metropolis sampling (see the presentation by David Poulin) and outline the analysis of the errors that arise due to imperfect simulation of Hamiltonian time evolutions and limited performance of phase estimation (finite accuracy and nonzero probability of failure).
