description: The University of British Columbia feels that there is a need for student interaction on campus, the absence of which can lead to deteriorating mental and emotional health. To combat this, the Alma Mater Society (AMS) have designated a vibrant social space to be constructed in the new Student Union Building. The objective of this report is to give recommendations on how to create this vibrant social space. Using examples of vibrant social spaces implemented in other universities, we determined that this social space needs to be dynamic so it can serve multiple purposes, while mainly serving as a game room. Research demonstrated that a DLP projector is the most suitable for a multimedia projector, which will mainly be used for watching sports but can also be used to convert the social space into a lecture hall or a movie theatre. Our analysis of lighting demonstrated that LED lighting is much superior to its alternatives in all three aspects of the triple bottom line assessment, and certain colours can also be used as “mood lighting”. All of this ties into our main objective, which we have achieved by recommending a variety of games for students that encourage interaction and can also be a good source of stress relief. The use of the triple bottom line assessment has allowed us to create a social space which is socially, economically, and environmentally feasible. The recommendations made in this report ensure that the social space will be a dynamic environment where students can feel welcome and where new relationships can be fostered.

description: Early pulmonary rehabilitation (PR), started during hospitalization or within the first month after discharge, has been shown to reduce exacerbations and improve health-related-quality of life (HRQoL) and exercise capacity. However, no randomized clinical trials (RCT) have compared the efficacy of PR started during hospitalization (DHPR) to PR initiated one month post-hospitalization (PHPR). We conducted an RCT to compare DHPR to PHPR in severe patients with COPD readmitted for exacerbations in a tertiary hospital setting. Patients were randomized to receive three months of DHPR or PHPR. Outcomes were assessed at completion of the PR programme and at months 3 and 9. A total of 53 patients (26 DHPR and 27 PHPR) were included. There were no between-group differences in the number of exacerbations (mean, 3.62 vs. 3.04 in the DHPR and PHPR groups, respectively; p = 0.403). Dyspnea in activities of daily living, exercise capacity, and all HRQoL parameters improved in the PHPR group. In the DHPR group, improvement was observed only for some HRQoL parameters. All gains in both groups were lost during follow-up. More adverse events were observed in the DHPR group (20 vs 5, p = 0.023), although none of these were clinically significant. In this sample of patients with severe COPD readmitted to the hospital for exacerbations, both approaches to PR were safe, but PHPR yielded better outcomes overall. These findings suggest that, PR should be initiated in patients with severe COPD only after hospital discharge when the patients’ clinical condition has stabilized.

description: The local linear trend and global linear trend models embody extreme assumptions about trends. According to the local linear trend formulation the level and growth rate are allowed to rapidly adapt to changes in the data path. On the other hand, the global linear trend model makes no allowance for structural change. In this paper we introduce a new model that, as well as encompassing the global linear trend and local linear trend models, allows for a range of "in between" cases. The theoretical properties of the autocovariance and forecast functions for this model suggest that it should be useful when neither a local linear trend nor a global linear trend is appropriate. A comparison of forecasting performance using real time series provides further support for this hypothesis.

description: Ginzburg-Landau bulk magnetization of itinerant electrons can provide a negative effective field in the Weiss model by coupling to localized magnetic moments. The coupling enforces remnant magnetization, which can be negative or positive depending on the sample magnetic history. Stable magnetic susceptibility of coupled nonequilibrium subsystems with magnetization reversal is always positive. Gauss-scale fields could be expected for switching between negative and positive remnant moments in semiconductors with coupling at ambient temperatures. Negative magnetization in ultra-high conducting polymers is also discussed within the developed framework.

Subjects: Research Methods/ Statistical Methods

description: This paper considers the analysis of cointegrated time series using principal components methods. These methods have the advantage of neither requiring the normalisation imposed by the triangular error correction model, nor the specification of a finite order vector autoregression. An asymptotically efficient estimator of the cointegrating vectors is given, along with tests for cointegration and tests of certain linear restrictions on the cointegrating vectors. An illustrative application is provided.

description: The favourable growth performance of SSA over the last 20 years (figure 15.1) has been accompanied by a modest decline in poverty, from 59 to 48 per cent over 1993-2010, i.e., much less than that recorded in South Asia (Ferreira, 2014). This aggregate trend, however, conceals substantial cross-country variations. The key question, then, is: How can such differences in poverty reduction rates be explained? The standard approach (Bourguignon, 2003) shows that a percentage change in poverty incidence can be decomposed into the percentage changes in the growth rate of GDP per capita and in the Gini coefficient, plus a small residual. In this regard, it must be noted that in SSA, the average GDP growth per capita oscillated in a narrow range, i.e., between 1.7 per cent in non-resource-rich countries and 2.6 per cent in resource-rich ones. The reason that poverty declined at different rates is, therefore, to be found in the divergence of inequality trends experienced by the SSA countries. Indeed, this chapter and Chapter 2 argue that over 1991-2011, income inequality rose in several countries but declined in a similar number.

description: The inequality issue has recently received growing attention in SSA from research, policy and political perspectives. In fact, while inequality is a key determinant of poverty and most other SDGs, its documentation, the analysis of its determinants and the debate on how to reduce it have been limited to date. The main reasons for this are the exclusive emphasis placed on growth by past development strategies, limited data availability and the heterogeneity of inequality levels, trends and determinants in the region. In particular, the picture that emerges from the review conducted in Chapter 2 for 1991-2011 points to a divergence of national inequality trends. The theoretical explanation of this divergence and the related empirical evidence have been discussed in Chapter 15, while other chapters analyse specific aspects of this problem. This chapter, in turn, focuses on econometrically testing the working hypotheses about the inequality determinants formulated in Chapter 2, explored on microdata in Chapters 12 and 13 and examined in macro and panel models in several other chapters of this book. The econometric test is conducted on the 29 countries included in the IID-SSA dataset, which covers 81.8 per cent of the African population and a greater share of its GDP. Thus, its conclusions can be considered to apply broadly to the region as a whole

description: Given a linear dynamical system affected by stochastic noise, we consider the problem of selecting an optimal set of sensors (at design-time) to minimize the trace of the steady state a priori or a posteriori error covariance of the Kalman filter, subject to certain selection budget constraints. We show the fundamental result that there is no polynomial-time constant-factor approximation algorithm for this problem. This contrasts with other classes of sensor selection problems studied in the literature, which typically pursue constant-factor approximations by leveraging greedy algorithms and submodularity (or supermodularity) of the cost function. Here, we provide a specific example showing that greedy algorithms can perform arbitrarily poorly for the problem of design-time sensor selection for Kalman filtering. We then study the problem of attacking (i.e., removing) a set of installed sensors, under predefined attack budget constraints, to maximize the trace of the steady state a priori or a posteriori error covariance of the Kalman filter. Again, we show that there is no polynomial-time constant-factor approximation algorithm for this problem, and show specifically that greedy algorithms can perform arbitrarily poorly.

title: Algebraic and computational aspects of quantum control and applications.
Creators: name: Pullen, Ivan Christopher Hugh
Publisher: name: The Open University

description: We investigate the problem of control of quantum systems. Various notions of controllability of quantum systems are discussed and Lie algebraic techniques are employed to derive necessary and sufficient conditions for the resulting degrees of controllability. The results are employed to study the degree of controllability for various model systems.

The problem of optimal control is formulated as a problem of maximisation of the expectation value of an observable of the system subject to dynamical constraints and costs. A class of iterative algorithms is discussed, and shown to converge to a solution of the Euler-Lagrange equations, which is a necessary condition for optimality of a solution. A numerical realisation of the algorithm is presented and potential implementation of the resulting control fields in the laboratory is discussed.

The algorithm is applied to find optimal control fields for a variety of applications including selective and simultaneous excitation of individual quantum dots in a globally addressed ensemble, creation of superposition states, and selective excitation of certain vibrational modes of a simple molecule such as Hydrogen Fluoride. In each case we systematically explore the parameter space of the algorithm to select solutions with desirable physical features from the multitude of possible choices.

As there are many possible optimal control fields which give similar yields the question of whether some are more robust than others is investigated. A number of optimal fields are analysed quantitatively in terms of robustness with regard to temporal and spectral noise affecting the fields, uncertainty in the model parameters and the effect of experimental limitations such as restrictions on the bandwidth of the fields. It is shown that whilst the solutions tend to be sensitive to uncertainty in the energy levels chosen for the model, they appear to be surprisingly tolerant to even severe bandwidth limitations.

description: We have investigated the effects of quantum fluctuations of quasiparticles on the operation of superconducting radio-frequency single-electron transistors (RF-SETs) for large values of the quasiparticle cotunneling parameter $α=8E_{J}/E_{c}$, where $E_{J}$ and $E_{c}$ are the Josephson and charging energies. We find that for $α>1$, subgap RF-SET operation is still feasible despite quantum fluctuations that renormalize the SET charging energy and wash out quasiparticle tunneling thresholds. Surprisingly, such RF-SETs show linearity and signal-to-noise ratio superior to those obtained when quantum fluctuations are weak, while still demonstrating excellent charge sensitivity.

description: Non-abelian horizontal symmetry has been considered to solve potentially SUSY flavor problem, but simple models are suffering from various problems. In this talk, we point out that (anomalous) U(1)_A gauge symmetry solves all the problems in a natural way, especially, in the E_6 grand unified theories. Combining the GUT scenario with anomalous U(1)_A gauge symmetry, in which doublet-triplet splitting and natural gauge coupling unification are realized, and realistic quark and lepton mass matrices are obtained including bi-large neutrino mixings, complete E_6* SU(3)_H (or E_6*SU(2)_H) GUTs can be obtained, in which all the three generation quarks and leptons are unified into a single multiplet (27,3) (or two multiplets (27,2+1)). This talk is based on Ref.[1].

description: We give a new proof of a theorem of Kleiner-Leeb: that any quasi-isometrically embedded Euclidean space in a product of symmetric spaces and Euclidean buildings is contained in a metric neighborhood of finitely many flats, as long as the rank of the Euclidean space is not less than the rank of the target. A bound on the size of the neighborhood and on the number of flats is determined by the size of the quasi-isometry constants. Without using asymptotic cones, our proof focuses on the intrinsic geometry of symmetric spaces and Euclidean buildings by extending the proof of Eskin-Farb's quasiflat with holes theorem for symmetric spaces with no Euclidean factors.

description: The levels of poverty and inequality in Africa are high in relation to the rest of the world. In order to reduce these twin ailments, more and better jobs need to be created. A key source of more and better jobs for developing countries is to be found in the manufacturing sector. Structural transformation involves the shift of productive resources from low productivity primary activities toward high productivity manufacturing activities. Therefore, understanding the constraints that countries face when trying to structurally transform and develop their manufacturing sector is important. In order to analyse the constraints to manufacturing growth, particularly in African countries, we employ the Atlas of Economic Complexity analytical framework developed by Hausmann & Hidalgo (2011). The analysis shows that, in general, African countries have not undergone manufacturing-led growth-inducing structural transformation. However, Africa is not one country, and the analysis demonstrates heterogeneity in the African experience, with some African countries exhibiting growth in their manufacturing sectors. The analysis indicates that the process of structural transformation is a path-dependent one, in which a country’s current productive capabilities embodied in its export structure, influence the extent to which it can shift production toward increased manufacturing activity. We argue that, with regard to manufacturing sector growth in Africa, there is no policy ‘silver bullet’. Rather, subsequent analysis needs to determine the specific productive capabilities required by manufacturing firms in African countries on a case-by-case basis.

description: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) recommendations for the initial bronchodilator to use in newly diagnosed chronic obstructive pulmonary disease (COPD) are based on trials of patients with longstanding disease and treatment. We compared the real world effectiveness of initial treatment with long-acting muscarinic agents (LAMA) versus long-acting beta2-agonists (LABA) on the incidence of exacerbations in newly diagnosed patients. We identified a cohort of patients with COPD, new users of a LAMA or LABA (not combined with an inhaled corticosteroid (ICS)) during 2002–2018, age 50 or older, from the UK’s CPRD database, and followed for one year. The hazard ratio (HR) of exacerbation estimated using the Cox regression model, weighted by fine stratification of propensity scores. The cohort included 40,538 initiators of LAMA and 10,680 of LABA. The adjusted hazard ratio (HR) of a first moderate or severe exacerbation comparing LAMA with LABA initiation was 0.96 (95% CI: 0.90–1.02), while for severe exacerbation it was 0.92 (95% CI: 0.75–1.12). The incidence of exacerbation on LAMA was significantly lower than on LABA (HR 0.88; 95% CI: 0.80–0.96) among patients with a prior exacerbation, and the HR of exacerbation increased with percent predicted FEV1. This study in the real world clinical setting of COPD treatment found that using a LAMA or a LABA (no ICS) as the initial bronchodilator is generally as effective at reducing exacerbation incidence and frequency. However, a LAMA may be more effective in patients with prior exacerbations, which supports the GOLD recommendations for newly diagnosed COPD. The role of airway obstruction on the effectiveness of bronchodilators warrants further investigation.

description: The equation of state of H2 adsorbed in the interstitial channels of a carbon nanotube bundle has been calculated using the diffusion Monte Carlo method. The possibility of a lattice dilation, induced by H2 adsorption, has been analyzed by modeling the cohesion energy of the bundle. The influence of factors like the interatomic potentials, the nanotube radius and the geometry of the channel on the bundle swelling is systematically analyzed. The most critical input is proved to be the C-H2 potential. Using the same model than in planar graphite, which is expected to be also accurate in nanotubes, the dilation is observed to be smaller than in previous estimations or even inexistent. H2 is highly unidimensional near the equilibrium density, the radial degree of freedom appearing progressively at higher densities.

description: The paper documents and explains the income inequality changes that have occurred in Sub-Saharan Africa over 1991-2011. After reviewing the causes of post-Independence income polarization, it shows that during the 2000s 17 countries recorded an inequality decline and 12 a rise. The paper then explores the determinants of this trend bifurcation by reviewing the changes recorded in a long list of inequality determinants and by testing their relevance by means of a multivariate macro-panel regression. The results indicate that the growth rate of GDP/capita is unrelated to inequality while its composition is closely associated with it. Improvements in the distribution of human capital improved inequality while lack of land reforms and high population growth increased it. Changes in global conditions had a mixed effect. While remittances and rising world agricultural prices appear to have been equalizing, rising FDI in extractive industries and a surge of terms of trade in resource-rich economies were regressive. ODA changes were statistically non-significant, but debt cancellation in HIPC-eligible countries reduced the Gini perceptibly. Domestic policy changes had a mixed effect. Where direct taxation and targeted social expenditure rose the impact on inequality was favourable. Among the macro-policies, trade liberalization was un-equalizing as it reduced the value added share of manufacturing, while a stable macroeconomy, fall in inflation and competitive exchange rate reduced income polarization. Exogenous shocks generated contrasting effects: the recent fall in HIV/AIDS incidence reduced inequality modestly, while conflict intensity increased it. Our estimates do not find a clear distributive effect of democratization. The paper concludes stressing the need to strengthen the informational basis to analyse various aspects of inequality, and to improve our understanding of the politics of distributive policies.

description: Quadriceps strength training is a key component of pulmonary rehabilitation (PR). Clinical interpretability of changes in muscle strength following PR is however limited due to the lack of cut-off values to define clinical improvement. This study estimated the minimal clinically important difference (MCID) for the isotonic and isometric quadriceps muscle strength assessed with the one-repetition maximum (1RM) and hand-held dynamometry (HHD) in people with chronic obstructive pulmonary disease (COPD) following PR. A secondary analysis of a real life non-randomised controlled study was conducted in people with COPD enrolled in a 12-week community-based PR programme. Anchor and distribution-based methods were used to compute the MCIDs. The anchors explored were the St. George’s respiratory questionnaire (SGRQ) and the six-minute walk test (6MWT) using Pearson’s correlations. Pooled MCIDs were computed using the arithmetic weighted mean (2/3 anchor, 1/3 distribution-based methods) and reported as absolute and/or percentage of change values. Eighty-nine people with COPD (84% male, 69.9 ± 7.9 years, FEV1 49.9 ± 18.9% predicted) were included. No correlations were found between changes in 1RM and the SGRQ neither between changes in HHD and the SGRQ and 6MWT (p > 0.05). Thus, anchor-based methods were used only in the MCID of the 1RM with the 6MWT as the anchor. The pooled MCIDs were 5.7Kg and 26.9% of change for the isotonic quadriceps muscle strength with 1RM and 5.2KgF for isometric quadriceps muscle strength assessed with HHD. The MCIDs found are estimates to improve interpretability of community-based PR effects on quadriceps muscle strength and may contribute to guide interventions.

description: Myelin figures are long thin cylindrical structures that typically grow as a dense tangle when water is added to the concentrated lamellar phase of certain surfactants. We show that, starting from a well-ordered initial state, single myelin figures can be produced in isolation thus allowing a detailed study of their growth and stability. These structures grow with their base at the exposed edges of bilayer stacks from which material is transported into the myelin. Myelins only form and grow in the presence of a driving stress; when the stress is removed, the myelins retract.

description: We present parameter learning in a Gaussian variational inference setting using only noisy measurements (i.e., no groundtruth). This is demonstrated in the context of vehicle trajectory estimation, although the method we propose is general. The paper extends the Exactly Sparse Gaussian Variational Inference (ESGVI) framework, which has previously been used for large-scale nonlinear batch state estimation. Our contribution is to additionally learn parameters of our system models (which may be difficult to choose in practice) within the ESGVI framework. In this paper, we learn the covariances for the motion and sensor models used within vehicle trajectory estimation. Specifically, we learn the parameters of a white-noise-on-acceleration motion model and the parameters of an Inverse-Wishart prior over measurement covariances for our sensor model. We demonstrate our technique using a 36~km dataset consisting of a car using lidar to localize against a high-definition map; we learn the parameters on a training section of the data and then show that we achieve high-quality state estimates on a test section, even in the presence of outliers. Lastly, we show that our framework can be used to solve pose graph optimization even with many false loop closures.

description: The constraint distribution in non-holonomic mechanics has a double role. On one hand, it is a kinematic constraint, that is, it is a restriction on the motion itself. On the other hand, it is also a restriction on the allowed variations when using D'Alembert's Principle to derive the equations of motion. We will show that many systems of physical interest where D'Alembert's Principle does not apply can be conveniently modeled within the general idea of the Principle of Virtual Work by the introduction of both kinematic constraints and variational constraints as being independent entities. This includes, for example, elastic rolling bodies and pneumatic tires. Also, D'Alembert's Principle and Chetaev's Principle fall into this scheme. We emphasize the geometric point of view, avoiding the use of local coordinates, which is the appropriate setting for dealing with questions of global nature, like reduction.

Constraining Alternate Models of Black Holes: Type I X-ray Bursts on Accreting Fermion-Fermion and Boson-Fermion Stars

description: The existence of black holes remains open to doubt until other conceivable options are excluded. With this motivation, we consider a model of a compact star in which most of the mass consists of dark particles of some kind, and a small fraction of the mass is in the form of ordinary nucleonic gas. The gas does not interact with the dark matter other than via gravity, but collects at the center as a separate fermionic fluid component. Depending on whether the dark mass is made of fermions or bosons, the objects may be called fermion-fermion stars or boson-fermion stars, respectively. For appropriate choices of the mass of the dark matter particles, these objects are viable models of black hole candidates in X-ray binaries. We consider models with a dark mass of 10 solar masses and a range of gas mass from 10^{-6} to nearly one solar mass, and analyse the bursting properties of the models when they accrete gas. We show that all the models would experience thermonuclear Type I X-ray bursts at appropriate mass accretion rates. Since no Type I bursts have been reported from black hole candidates, the models are ruled out. The case for identifying black hole candidates in X-ray binaries as true black holes is thus strengthened.

description: We confirm the existance of magneto-resistance oscillations in a microwave-irradiated two-dimensional electron gas, first reported in a series of papers by Zhudov et al. and Mani et al. In our experiments, on a sample with a more moderate mobility, the microwave induced oscillations are observed not only in the longitudinal - but also in the transverse-resistance (Hall resistance). The phase of the oscillations is such that the decrease (increase) in the longitudinal resistance is accompanied by an increase (decrease) in the absolute value of the Hall resistance. We believe that these new results provide valuable new information to better understand the origin of this interesting phenomenon.

An investigation into a Bring Your Own Container food outlet for the new SUB

Year: 2014

description: In 2010, the Alma Mater Society (AMS) at the University of British Columbia (UBC) made the decision to construct a new Student Union Building (SUB). The AMS is considering operating one of the eleven food outlets as a Bring Your Own Container (BYOC) outlet, as part of the AMS Lighter Footprint Strategy. This report compares the difference between a BYOC food outlet and a traditional disposable container food outlet. The BYOC outlet will serve customers only if they provide their own container. For this investigation, some important factors that can impact the success of the food outlet are disregarded. These factors include: the location and types of food available. As a triple bottom line analysis of the BYOC concept, the report involves conducting environmental, social and economic evaluations of the concept. The analysis uses sources including previous reports on the AMS Food and Beverage Department and UBC Food Services, existing food sustainability strategies at UBC, and data collection through interviews and surveys. Overall, it is recommended that the AMS implement the BYOC project in the New SUB. The BYOC concept requires a low initial cost and assists in promoting a sustainable lifestyle within UBC. However, there are some drawbacks that will affect the business’s profitability.

Low-density series expansions for directed percolation IV. Temporal disorder

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We introduce a model for temporally disordered directed percolation in which the probability of spreading from a vertex $(t,x)$, where $t$ is the time and $x$ is the spatial coordinate, is independent of $x$ but depends on $t$. Using a very efficient algorithm we calculate low-density series for bond percolation on the directed square lattice. Analysis of the series yields estimates for the critical point $p_c$ and various critical exponents which are consistent with a continuous change of the critical parameters as the strength of the disorder is increased.

description: Correlation of charm quark - charm antiquark in $γp$ scattering are calculated in the $k_t$-factorization approach. We apply different unintegrated gluon distributions (uGDF) used in the literature. The results of our calculations are compared with very recent experimental results from the FOCUS collaboration. The CCFM uGDF developed recently by Kwieciński et al. gives a good description of the data. New observables are suggested for future studies. Predictions and perspectives for the HERA energies are presented.
