description: We investigate the impact of photorefractive effect on lithium niobate integrated quantum photonic circuits dedicated to continuous variable on-chip experiments. The circuit main building blocks, i.e. cavities, directional couplers, and periodically poled nonlinear waveguides are studied. This work demonstrates that, even when the effect of photorefractivity is weaker than spatial mode hopping, they might compromise the success of on-chip quantum photonics experiments. We describe in detail the characterization methods leading to the identification of this possible issue. We also study to which extent device heating represents a viable solution to counter this effect. We focus on photorefractive effect induced by light at 775 nm, in the context of the generation of non-classical light at 1550 nm telecom wavelength.

A hard stone people : social relations and the nation state in the Vaturanga District, Guadalcanal, Solomon Islands
Creators: name: Ryniker, David Craig
Publisher: name: University of British Columbia
Year: 2009

description: Studies of nation-states have tended to emphasize how they form a common national culture and the systems and institutions involved. This has included notions about the past, territory, language, and popular culture, among others. Many such studies hypothesize the role of media and publishing in establishing the modern nation-state as a sort of "imagined community" or a "creolized culture." This study, which looks at a local people called the Vaturanga, who live in northwestern Guadalcanal in the Solomon Islands, approaches the subject from the point of view of economic and communicative behaviours. It is my contention that the dynamic events and features frequently seen in modern and especially post-colonial nation-states can best be explained by reference to a constellation of relationships or associations: the divergent social networks to which people have access. The Vaturanga and their neighbours in rural Guadalcanal and their distant kin in town, illustrate these divergent social networks in such matters as economic change, ethnic relations, language and communication, and the mass media. Economic behaviours must be maintained by communication. This includes both the avenues of communication, and the meanings and symbols employed. This study especially focuses on the latter as a means to understand and comprehend the lives of the Vaturanga.

description: Low-frequency quadrupole vibrations in deformed ${}^{36,38,40}$Mg are studied by means of the deformed Quasiparticle-RPA based on the coordinate-space Hartree-Fock-Bogoliubov formalism. Strongly collective $K^π=0^{+}$ and $2^{+}$ excitation modes (carrying 10-20 W.u.) are obtained at about 3 MeV. It is found that dynamical pairing effects play an essential role in generating these modes. It implies that the lowest $K^π=0^{+}$ excitation modes are particularly sensitive indicators of dynamical pairing correlations in deformed nuclei near the neutron drip line.

description: There are numerous approximate color transforms reported in the literature that aim to reduce display power consumption by imperceptibly changing the color content of displayed images. To be practical, these techniques need to be content-aware in picking transformation parameters to preserve perceptual quality. This work presents a computationally-efficient method for calculating a parameter lower bound for approximate color transform parameters based on the content to be transformed. We conduct a user study with 62 participants and 6,400 image pair comparisons to derive the proposed solution. We use the user study results to predict this lower bound reliably with a 1.6% mean squared error by using simple image-color-based heuristics. We show that these heuristics have Pearson and Spearman rank correlation coefficients greater than 0.7 (p<0.01) and that our model generalizes beyond the data from the user study. The user study results also show that the color transform is able to achieve up to 50% power saving with most users reporting negligible visual impairment.
Nonhierarchical alternate routing in a circuit-switched network at Telus
Creators: name: Kabanuk, Steven Joseph
Publisher: name: University of British Columbia
Year: 2009

description: The primary objective of this project was to identify opportunities and develop solutions that will enable TELUS to reduce the cost of maintaining and improving a portion of their existing local network in British Columbia, Canada. To realize this objective, the focus was on optimal routing of calls assuming a fixed network capacity. Our hypothesis was that by changing the routing rules between an origin switch and a destination switch, we could alleviate pressure from congested areas in the network by diverting traffic through less utilized areas. Three types of optimization models have been developed: two linear programs, a mixed-integer model, and a nonlinear program. Irrespective of their objective functions, the purpose of each model was to suggest new sets of routes for each pair of switches. Development of these models and assessment of their ability to suggest routes which reduced the number of blocked calls in the simulated network was the central focus of this thesis. The modeling results were compared with the existing routing.rules in a network simulator. It appears that TELUS could benefit from implementation of alternate nonhierarchical routing rules. Specifically, employing the combined routing rules - that attempt the direct route first, then attempt the 2-link Maximum Linear Model routes from the 11:00-12:00 time interval, and finally the currently used alternate routes - generated the best routing table of those tested. Furthermore, these routing rules can be employed throughout the day without the need for change. The results from the trunk reservation analysis suggest that implementation of a uniform policy would be of marginal value.

description: In this article we find finite field analogues of certain product formulas satisfied by the classical hypergeometric series. We express product of two ${_2}F_1$-Gaussian hypergeometric series as ${_4}F_3$- and ${_3}F_2$-Gaussian hypergeometric series. We use properties of Gauss and Jacobi sums and our earlier works on finite field Appell series to deduce these product formulas satisfied by the Gaussian hypergeometric series. We then use these transformations to evaluate explicitly some special values of ${_4}F_3$- and ${_3}F_2$-Gaussian hypergeometric series. By counting points on CM elliptic curves over finite fields, Ono found certain special values of ${_2}F_1$- and ${_3}F_2$-Gaussian hypergeometric series containing trivial and quadratic characters as parameters. Later, Evans and Greene found special values of certain ${_3}F_2$-Gaussian hypergeometric series containing arbitrary characters as parameters from where some of the values obtained by Ono follow as special cases. We show that some of the results of Evans and Greene follow from our product formulas including a finite field analogue of the classical Clausen's identity.

description: This study assesses the effectiveness of remediation activities of Grade 5 pupil’s academic performance in the subject Technology and Livelihood Education (TLE). The study used an experimental pretest-posttest design. We chose two schools in the experiment and each school has a class with 50 pupils each. We assigned one school as the independent group and the other one was the experimental group. The researchers worked with the respective teachers in TLE to determine the level of academic performance of the students. First, we administered a pretest during their first grading period. The results for both schools were not impressive, prompting the researchers to advise remediation activities to the experimental group. We advised the independent group to do the usual learning methods. After the intervention, the researcher performed another set of assessment using the results of the second grading period performance. The researchers used a paired t-test to check for significant differences in the scores of the groups. The study found that there is a significant difference in the scores of the pupils after the remediation intervention. Therefore, the researchers concluded that remediation activities can affect the academic performance of the students.

description: The high dose gradients near the source characteristics of brachytherapy are equivalent to nefarious effects if unnoticed errors take place during the patient treatment. In vivo dosimetry is the only method to quantify the delivered dose. Previous studies to this one, have characterized potential detectors that can be used as in vivo dosimeter. Some of them have focused on the source tracking topic in HDR brachytherapy. The aim of this study is to perform 3D source position reconstruction by combining in vivo dosimetry measurements from two independent detector systems. The first was based on multiple (three) plastic scintillator detectors and the second on a single inorganic crystal (CsI:Tl). By combining two detector responses, we enabled the determination of the absolute source coordinates in 3D space. The method in this study proposed can be extended to the combination of different systems.

description: Using a semiclassical approach, we study the persistent magnetization current of a mesoscopic ferrimagnetic ring in a nonuniform magnetic field. At zero temperature, there exists persistent spin current because of the quantum fluctuation of magnons, similar to the case of an antiferromagnetic spin ring. At low temperature, the current shows activation behavior because of the field-induced gap. At higher temperature, the magnitude of the spin current is proportional to temperature T, similar to the reported result of a ferromagnetic spin ring.

description: This study investigated the effects of ill-health and disability in Activities of Daily Living (ADL) on the post-harvest wage employment participation of working-age smallholder agricultural households' members in Nigeria. Panel datasets of the Nigerian Living Standard Measurement Study, Integrated Survey on Agriculture (LSMS-ISA) were used. The measures of households' members ill-health used included: the number of days lost to ill-health disability and categories of ADL indexes such as physical fitness ability, participation difficulties, and sight and hearing impairments. The data were analysed using Factor analysis and Panel data Probit model. The results showed that 63% of the wage employed agricultural households' members were males, with 70% between 25 and 55 years of age. Over 90% of the respondents had primary education. Also, age, level of formal education, health status and sector of residence were the significant factors influencing agricultural households' wage employment participation. Specifically, increased illness days pushed the males and rural working-age individuals, into post-harvest wage employment. Good physical and mental health, a higher level of formal education, especially among the females in the rural areas are the significant factors affecting agricultural households' post-harvest wage employment participation. Thus, there is need for health investment for the maintenance of the respondents' health stock to maximise agricultural households' economic potential. The study provided new empirical evidence on the levels of functioning and disability in ADL and influence of days lost to illness and disability in ADL on the post-harvest wage employment participation in Nigeria. Implications for the policy will be to channel government financing efforts at encouraging the attainment of formal education, healthcare investment amongst the agricultural communities in the country. This is important to achieve enhanced human capital stocks, agricultural households' welfare and labour market productivity.

description: Recently, generative machine-learning models have gained popularity in physics, driven by the goal of improving the efficiency of Markov chain Monte Carlo techniques and of exploring their potential in capturing experimental data distributions. Motivated by their ability to generate images that look realistic to the human eye, we here study generative adversarial networks (GANs) as tools to learn the distribution of spin configurations and to generate samples, conditioned on external tuning parameters, such as temperature. We propose ways to efficiently represent the physical states, e.g., by exploiting symmetries, and to minimize the correlations between generated samples. We present a detailed evaluation of the various modifications, using the two-dimensional XY model as an example, and find considerable improvements in our proposed implicit generative model. It is also shown that the model can reliably generate samples in the vicinity of the phase transition, even when it has not been trained in the critical region. On top of using the samples generated by the model to capture the phase transition via evaluation of observables, we show how the model itself can be employed as an unsupervised indicator of transitions, by constructing measures of the model's susceptibility to changes in tuning parameters.

If the marginals of the measure have exponential moments, Gaussian asymptotics for the distribution of the average marginal implies Gaussian asymptotics for the distribution of most individual marginals. We show applications to measures of geometric origin.

description: Diversified growth and complex business environment has increased the financial risk. When firms are faced with a variety of risk, they used to manage this risk by hedging instruments. Hedging instruments increase transparency and control swing of cash flow and net income in the firms. This paper investigates effect of risk management on swing of cash flow and net income with selected 100 firms for 1386 to 1391 with using of regression models in SPSS. Investment with requirement of hedging and risk management for controlling swing of cash flows and net income are no effect in Iran’s capital market but they are effective in future forecast of swing cash flows and controlling on it. Also three variables of stock price, opportunities for investment growth and net profit last year's swing are effective variables in controlling and forecast of net income and cash flow’s swing that emphasize on shareholders’ understanding effect from controlling of risk in firm.

description: Recently remarkable progress in quantum technology has been witnessed. In view of this it is important to investigate an open quantum system as a model of such quantum devices. Quantum devices often require extreme conditions such as very low temperature for the devices to operate. Dynamics can be non-Markovian in such a situation in contrast with Markovian dynamics in high temperature regime. This observation necessitates us to investigate a non-Markovian open quantum system, both theoretically and experimentally. In this paper, we report two important results: 1) Exact solution of a simple but non-trivial theoretical model and 2) demonstration of this model by NMR experiments, where non-Markovianity is continuously controllable. We observe qualitative agreement between theory and experiment.

title:  Investigation of a Validation Technique for the Registration of 3D Points Directly to Subjects with Pectus Excavatum
Creators: name: Cuper, Taryn Tacosa
Publisher: name: Old Dominion University Libraries
Year: 2008

description: Pectus excavatum (PE) is a congenital deformity that results in a "caved in" appearance of the chest wall. The cause of this condition is unknown, but research suggests that an in vivo investigation of the biomechanical properties of the costal cartilages of subjects with PE may offer insight. Force and deflection measurements are proposed as a way to obtain this data; however, accurate location of cartilage from the skin level would be required for such an effort. Given the multiple potential sources of error with this process, a validation procedure to ensure the appropriateness of the findings must be developed; this is the focus of this research. Subjects with uncorrected PE paiticipated in this research. Both computed tomography (CT) scans and 3D laser surface scans of a subject's chest area were used to develop the validation technique, which utilizes the iterative closest point (ICP) algorithm for registration. As a result, robust recommendations with respect to surface scan sweeps registration, mesh-to-point cloud sampling distance, surface scan acquisition, creation of the rib cage model from CT data, and an approach to rough model alignment prior to registration have been made. Future steps following this research include the investigation of accurate point identification on and data collection from a subject with PE.

description: Facing growing competition from online rivals, the retail industry is increasingly investing in their online shopping platforms to win the high-stake battle of customer' loyalty. User experience is playing an essential role in this competition, and retailers are continuously experimenting and optimizing their user interface for better user experience. The cost of experimentation is dominated by the opportunity cost of providing a suboptimal service to the customers. Through this paper, we demonstrate the effectiveness of opportunistic bandits to make the experiments as inexpensive as possible using real online retail data. In fact, we model user interface experimentation as an opportunistic bandit problem, in which the cost of exploration varies under a factor extracted from customer features. We achieve significant regret reduction by mitigating costly exploration and providing extra contextual information that helps to guide the testing process. Moreover, we analyze the advantages and challenges of using opportunistic bandits for online retail experimentation.

The domain specificity of the resources required for sentence processing
Creators: name: Kennedy, Michelle
Publisher: name: University of British Columbia
Year: 2009

description: Working memory has been proposed as the cognitive resource system that supports storage and processing while a task is being carried out. The present study investigates the nature of the resources underlying working memory tasks in different cognitive domains and how they relate to sentence processing. Specifically, it aims to determine whether the predictive ability of a working memory task relies more on similarity of cognitive domain or on similarity of the sequence of demands to the sentence processing task. Thirty young normal participants read sentences varying in syntactic complexity in a selfpaced reading experiment. Working memory was assessed using Daneman and Carpenter's reading span task (1980), Waters and Caplan's reading span task (1996a) and two new mathematical and visuo-spatial tasks designed to match the sequence of demands in subjectobject and object-subject relative clause sentences. Correlation analyses examined the relationship between performance on each working memory task and sentence comprehension. The results replicate previous findings of a main effect on reading time of syntactic complexity and of syntactic ambiguity for reduced relative sentences. Complexity effects were observed for subject-object conditions on the mathematical and visuo-spatial tasks. Significant correlations were observed between critical regions of subject-object sentences and (a) mathematical operations, (b) visuo-spatial operations, and (c) one version of the Waters and Caplan reading span task. This pattern of results cannot be explained by theories which incorporate a dissociation between verbal and nonverbal processing resources. The results support a connectionist approach in which familiarity with sequences of storage and processing demands across tasks explains individual differences in processing ability.

description: In current economic environment, firms consider human capital as one of their major sources of competitive advantage, and human capital reporting is a reporting system of firms providing information about employees’ knowledge, abilities, capabilities, and motivations. This study tests the relation between human capital reporting and intangible assets of firms, for the first time. The sample includes 131 firms listed in Tehran Stock Exchange during 2010 to 2014, and panel data regression method is used to process and test the hypotheses. The results show an inverse relationship between intangible assets and human capital reporting of firms listed in Tehran Stock Exchange. In other words, voluntary disclosure of financial and non-financial information about investment in human capital is an alternative to the identification of intangible assets in financial reporting. Accordingly, there is an inverse relationship between the mandatory disclosure of intangible assets and voluntary disclosure of human capital, meaning that voluntary disclosure plays an alternative role for mandatory disclosure.

description: We present a mass-temperature profile of gas within the central 10 kpc of a small sample of cool core clusters. The mass of the hottest gas phases, at 1.5 and 0.7 keV, is determined from X-ray spectra from the XMM Reflection Grating Spectrometers. The masses of the partially ionised atomic and the molecular phases are obtained from published H$α$ and CO measurements. We find that the mass of gas at 0.7 keV in a cluster is remarkably similar to that of the molecular gas. Assuming pressure equilibrium between the phases, this means that they occupy volumes differing by $10^5$. The molecular gas is located within the HU nebula which is often filamentary and coincides radially and in position angle with the soft X-ray emitting gas.

description: The silicon-vacancy (SiV) and nitrogen-vacancy (NV) centers in diamond are commonly regarded as prototypical defects for solid-state quantum information processing. Here we show that when silicon and nitrogen are simultaneously introduced into the diamond lattice these defects can strongly interact and form larger complexes. Nitrogen atoms strongly bind to Si and SiV centers and complex formation can occur. Using a combination of hybrid density functional theory (DFT) and group theory, we analyze the electronic structure and provide various useful physical properties, such as hyperfine structure, quasi-local vibrational modes, and zero-phonon line, to enable experimental identification of these complexes. We demonstrate that the presence of substitutional silicon adjacent to nitrogen significantly shifts the donor level toward the conduction band, resulting in an activation energy for the SiN center that is comparable to phosphorus. We also find that the neutral SiNV center is of particular interest due to its photon emission at $\sim$1530 nm, which falls within the C band of telecom wavelengths, and its paramagnetic nature. In addition, the optical transition associated with the SiNV$^0$ color center exhibits very small electron--phonon coupling (Huang--Rhys factor~=~0.78) resulting in high quantum efficiency (Debye-Waller factor = 46\%) for single-photon emission. These features render this new center very attractive for potential application in scalable quantum telecommunication networks.

The most obvious way to encode a qubit optically is as a superposition of the vacuum and a single photon in one mode -- so-called "single-rail" logic. Until now this approach was thought to be prohibitively expensive (in resources) compared to "dual-rail" logic where a qubit is stored by a photon across two modes. Here we attack this problem with real-time feedback control, which can realize a quantum-limited phase measurement on a single mode, as has been recently demonstrated experimentally. We show that with this added measurement resource, the resource requirements for single-rail LOQC are not substantially different from those of dual-rail LOQC. In particular, with adaptive phase measurements an arbitrary qubit state $α\ket{0} + β\ket{1}$ can be prepared deterministically.

description: Low transparency causes information asymmetry, increases risk of information and thus decreases shareholder confidence. Voluntary disclosure with improvement of financial information transparency may raise investors' awareness, increase shareholders confidence and decrease cost of capital. This study investigates that information asymmetry and cost of capital decreases are as consequences of higher level voluntary disclosure. The sample consists of 146 firms listed in Tehran Stock Exchange in the period from 2009 to 2013. Structural equation modeling is used to examine the hypothesis and survey direct effects of improved voluntary disclosure and indirect effects of other variables on the possible consequences. The findings show that voluntary disclosure as an information transparency mechanism reduces shares bid and ask and increases their turnover. Also the voluntary disclosure is one of the reducing factors of the cost of capital. Voluntary disclosure with improving corporate information transparency reduces information risk, investors' return expectations as well as the cost of capital

description: Elastin-like polypeptides (ELPs) undergo a sharp solubility transition from low temperature solvated phases to coacervates at elevated temperatures, driven by the increased strength of hydrophobic interactions at higher temperatures. The transition temperature, or 'cloud point', critically depends on sequence composition, sequence length, and concentration of the ELPs. In this work, we present a temperature-dependent, implicit solvent, sequence-specific coarse-grained (CG) simulation model that reproduces the transition temperatures as a function of sequence length and guest residue identity of various experimentally probed ELPs to appreciable accuracy. Our model builds upon the self-organized polymer model introduced recently for intrinsically disordered polypeptides (SOP-IDP), and introduces a semi-empirical functional form for the temperature-dependence of hydrophobic interactions. In addition to the fine performance for various ELPs, we demonstrate the ability of our model to capture the thermal compactions in dominantly hydrophobic intrinsically disordered polypeptides (IDPs), consistent with experimental scattering data. With the high computational efficiency afforded by the CG representation, we envisage that the model will be ideally suited for simulations of large-scale structures such as ELP networks and hydrogels, as well as agglomerates of IDPs.
The Kardar-Parisi-Zhang equation in the weak noise limit: Pattern formation and upper critical dimension

description: We extend the previously developed weak noise scheme, applied to the noisy Burgers equation in 1D, to the Kardar-Parisi-Zhang equation for a growing interface in arbitrary dimensions. By means of the Cole-Hopf transformation we show that the growth morphology can be interpreted in terms of dynamically evolving textures of localized growth modes with superimposed diffusive modes. In the Cole-Hopf representation the growth modes are static solutions to the diffusion equation and the nonlinear Schroedinger equation, subsequently boosted to finite velocity by a Galilei transformation. We discuss the dynamics of the pattern formation and, briefly, the superimposed linear modes. Implementing the stochastic interpretation we discuss kinetic transitions and in particular the properties in the pair mode or dipole sector. We find the Hurst exponent H=(3-d)/(4-d) for the random walk of growth modes in the dipole sector. Finally, applying Derrick's theorem based on constrained minimization we show that the upper critical dimension is d=4 in the sense that growth modes cease to exist above this dimension.

description: We derive model-independent, "naturalness" upper bounds on the magnetic moments μ_νof Dirac neutrinos generated by physics above the scale of electroweak symmetry breaking. In the absence of fine-tuning of effective operator coefficients, we find that current information on neutrino mass implies that |μ_ν| < 10^(-14) Bohr magnetons. This bound is several orders of magnitude stronger than those obtained from analyses of solar and reactor neutrino data and astrophysical observations.

description: The subject of this work is the analysis of hadronic decays of the exotic meson $π_{1}$ in a fully relativistic formalism, and comparison with the nonrelativistic results. The relativistic spin wave functions of mesons and hybrids are constructed based on unitary representations of the Lorentz group. The radial wave functions are obtained from phenomenological considerations of the mass operator. We find that the decay channels $πb_{1}$ and $πf_{1}$ are favored, in agreement with the results obtained using other models, thus indicating some model independence of the S+P selection rules.

description: Violent solar eruptions are often accompanied by relativistic beams of charged particles. In the solar context, they are referred to as SPEs (Solar Particle Events) and are known to generate a characteristic swept-frequency radio burst. Due to their ionizing potential, such beams influence atmospheric chemistry and habitability. Radio observations provide a crucial discriminant between stellar flares that do and do not generate particle beams. Here I use solar empirical data and semi-quantitative theoretical estimates to gauge the feasibility of detecting the associated radio bursts. My principal conclusion is that a dedicated search for swept frequency radio bursts on second-timescales in existing low-frequency ($ν\lesssim 10^2\,{\rm MHz}$) datasets, while technically challenging, will likely evidence high energy particles beams in Sun-like stars.

description: Over the last few decades, extensive previous studies of the nonlinear response of metal nanoparticles report a wide variation of nonlinear coefficients, thus, revealing a highly confused picture of the underlying physics. This naturally prevents rational design of these systems for practical devices. Here, we provide a systematic study of the nonlinear response of metal spheres under continuous wave illumination within a purely thermal model. We characterize the strong dependence of the temperature rise and overall thermo-optic nonlinear response on the particle size and permittivity, on the optical and thermal host properties, as well as on the thermo-derivatives of these properties. This dependence on the non-intrinsic parameters explains why it is inappropriate to extract an intrinsic nonlinear coefficient from a specific system. Despite the revealed complex multi-parameter dependence, we managed to uncover a rather simple behaviour of the nonlinear response. In particular, we show that the nonlinearity coefficients exhibit a dependence on the illumination intensity which mimics the dependence of the temperature itself on the illumination intensity, namely, it grows for small nanoparticle sizes, reaches a maximum and then decreases monotonically for larger nanoparticles. The improved modelling allows us to demonstrate an overall nonlinear response which is about a 1000 times higher than in other strongly nonlinear systems (e.g., $ε$-near-zero systems); it also provides an excellent match to experimental measurements of the scattering from a single metal nanoparticles, thus, confirming the dominance of the thermal nonlinear mechanism. Our work lays the foundations for an overall evaluation of previous studies of the nonlinear response of metal-dielectric system under general conditions.
