description: The combined effect of bulk and interface electron-phonon couplings on the transport properties is investigated in a model for organic semiconductors gated with polarizable dielectrics. While the bulk electron-phonon interaction affects the behavior of mobility in the coherent regime below room temperature, the interface coupling is dominant for the activated high $T$ contribution of localized polarons. In order to improve the description of the transport properties, the presence of disorder is needed in addition to electron-phonon couplings. The effects of a weak disorder largely enhance the activation energies of mobility and induce the small polaron formation at lower values of electron-phonon couplings in the experimentally relevant window $150 K

description: In experiments where ultraviolet light produces aerosols from trace amounts of ozone, sulphur dioxide, and water vapour, the number of additional small particles produced by ionization by gamma sources all grow up to diameters larger than 50 nm, appropriate for cloud condensation nuclei. This result contradicts both ion-free control experiments and also theoretical models that predict a decline in the response of larger particles due to an insufficiency of condensable gases (which leads to slower growth) and to larger losses by coagulation between the particles. This unpredicted experimental finding points to a process not included in current theoretical models, possibly an ion-induced formation of sulphuric acid in small clusters.

В рамках моделей толпы, основанных на поведении частиц, рассматривается использование потенциала Леннарда-Джонса в качестве основной «социальной силы», определяющей взаимодействие между индивидуумами. Выполненная с помощью программного пакета Mathematica симуляция подтверждает для этого подхода наличие сложных эмергентных феноменов поведения толпы, описанных в модели Хелбинга и другими авторами.
description: In this paper we provide the short overview of the currently existing approaches to modeling the crowd behavior. We consider the crowd as a set of particles moving under influence of physical, social and psychological forces. Starting from the Helbing’s social forces model to describe the crowd motion we introduce Lennard-Johnes potential for modeling interaction force between individuals in the crowd. We show that Lennard-Johnes potential can account for the people’s desire to preserve an optimal physical and social distance between each other; however, some modifications needs to be introduced in its calculations to account for directional anisotropy and other physical and behavioral aspects of motion of people within the crowd. In order to provide a performance evaluation of this model, we show a preliminary set of results obtained in a simulated scenario.

description: The ability to predict the thermodynamic conditions which result in asphaltene precipitation and its severity has many applications in industry. Asphaltene precipitation can be interpreted as a result of the competition between physical and association interactions between asphaltene molecules and asphaltene molecules with other mixture components. Hence, the CPA EoS is an excellent choice for modelling this phenomenon. In this thesis, a new version of the CPA EoS was developed. Efficient and reliable phase equilibrium calculation programs including isothermal flash and phase envelope constructor programs were prepared. A comparison of the results using the developed programs and commercial software revealed abilities of the developed programs. The asphaltene precipitation modelling results were compared to those of Li and Firoozabadi who used a slightly different version of the CPA EoS. The case studies and conditions studied in this thesis presented some unnoticed behaviours and a general improvement over their results.

description: A system analysis of the system of analytical control and management of technological parameters of cotton-cleaning production was performed. At the same time, the control system is studied as an adaptive control object that quickly changes its parameters depending on the actual state of the controlled technological parameters. A method for determining the frequency of removal of technological parameters based on the methods of mathematical statistics and based on the analysis of experimental data of a particular process is proposed. The functional dependence of the original variables from the information obtained from the system sensors. The source data is formalized as a system of equations. Depending on the type of signals (additivity, multiplicativity), the system of equations have different dimensions, which is easily solved in the usual way. To account for the probability of changes in input signals, the optimal data capture frequencies are determined. A method based on the realization of the difference between sets of factors is proposed to eliminate the randomness of signal changes. Proposed partitioning the set of values of input signals generated by changing each of the factors on identical two subsets, the first of which is formed on the basis of all possible values of the monitored parameters, and the second constant constituting the input. This circumstance determines the definition of the difference of sets.

description: The Sun is the nearest astrophysical source with a very intense emission in the X-ray band. The study of energetic events, such as solar flares, can help us to understand the behaviour of the magnetic field of our star. There are in the literature numerous studies published about polarization predictions, for a wide range of solar flares models involving the emission from thermal and/or non-thermal processes, but observations in the X-ray band have never been exhaustive. The gas pixel detector (GPD) was designed to achieve X-ray polarimetric measurements as well as X-ray images for far astrophysical sources. Here we present the possibility to employ this instrument for the observation of our Sun in the X-ray band.

description: Successful resettlement of all refugee groups is a matter of interest to both the host society and the newcomers. The current study was designed to explore the resettlement experience of African refugee mothers who are relocated to Canada/Calgary with children and without a spouse/partner. The design took a qualitative approach in which seven refugee single mothers from Africa participated in semi-structured interviews. The Critical Incident Technique (Flanagan 1954), supplemented by Thematic Analysis (Braun & Clarke, 2006), was used to conduct data analyses. Several categories (Support, Self Preservation, Adjustment to Canadian Ways, Awareness of Personal Limitations, Housing, Education, Finances, Parenting, Sexual Assault) and themes (Hopes and Dreams, Changes, Benefits, Psychological Distress, Looking to the Future, Advice for Those Considering Relocation) were formulated to describe the experience of making Canada home. The findings are discussed in relation to existing literature and implications for theory, research, and practice are presented.

description: We have investigated the driven dynamics of a superconducting flux qubit that is tunably coupled to a microwave resonator. We find that the qubit experiences an oscillating field mediated by off-resonant driving of the resonator, leading to strong modifications of the qubit Rabi frequency. This opens an additional noise channel, and we find that low-frequency noise in the coupling parameter causes a reduction of the coherence time during driven evolution. The noise can be mitigated with the rotary-echo pulse sequence, which, for driven systems, is analogous to the Hahn-echo sequence.

description: In this work, the PLECHDE model with Granda-Oliveros (G-O) IR-cutoff is studied. The evolution of dark energy density, deceleration and EoS parameters are calculated. I demonstrate that under a condition, our universe can accelerate near the phantom barrier at present time. We calculate these parameters also in PLECHDE at Ricci scale, when when $α=2$ and $β=1$, and at last a comparison between Ricci scale, G-O cutoff and non-corrected HDE without matter field with G-O cutoff is done. The correspondence between this model and some scalar field of dark energy models is established. By this method, the evolutionary treatment of kinetic energy and potential for quintessence, tachyon, K-essence and dilaton fields, are obtained. I show that the results has a good compatibility with previous work in the limiting case of flat, dark dominated and non corrected holographic dark energy.

subject: Loss-of-Function Mutation

description: Cardiac ryanodine receptors (RyR2) are intracellular Ca2+ release channel localized in the sarco/endoplasmic reticulum (SR/ER). Mutations of RyR2 are linked to arrhythmias and diseases. Interestingly, most of the RyR2 mutations are gain-of-function (GOF) mutations that increase the sensitivity of the channel to activation by luminal and/or cytosolic Ca2+. A4860G, located in the transmembrane domain, is the first loss-of-function (LOF) RyR2 mutation that diminishes luminal Ca2+ activation of RyR2 and abolishes spontaneous Ca2+ release. This finding raises an interesting question of whether there is more LOF RyR2 mutations that present and represent a distinct entity of arrhythmia that has yet to be appreciated. Cardiac alternans is described as a periodic, beat-to-beat alternation in every heartbeat. It is a well-recognized risk factor of ventricular fibrillation (VF) and sudden cardiac death (SCD). Ca2+ alternans is believed to be the primary cause of cardiac alternans but the mechanism underlying Ca2+ alternans remains unclear. The goal of this study is to understand the role of suppressed RyR2 function in cardiac alternans and VF. Clinical evaluations on idiopathic VF patients carrying RyR2-A4860G or RyR2-D4646A mutations have shown no arrhythmias during exercise stress test. Our studies have found three additional LOF RyR2 mutations- E4146K, D4646A, and G4936R. E4146K and D4646A suppress caffeine-induced Ca2+ release and abolish spontaneous Ca2+ release in HEK293 cells, and suppress or diminish both cytosolic or luminal Ca2+ activation of RyR2 channel in lipid bilayers. RyR2-G4936R, non-functional itself, exerts a dominant negative impact on WT function. RyR2-E4872Q+/- mice, with suppressed RyR2 function, prolong SR Ca2+ release refractoriness and enhance the propensity of cardiac alternans in intact heart. RyR2KO mice with reduced RyR2 level are also susceptible to cardiac alternans. Both mouse models are resistant to stress-triggered CPVT. Caffeine, which enhances RyR2 activity and the propensity for CPVT, suppresses Ca2+ alternans; whereas carvedilol, a beta-blocker that suppresses RyR2 activity and CPVT, promotes Ca2+ alternans in RyR2-E4872Q+/- hearts. On the other hand, the GOF mutation RyR2-R4496C increases resistance to alternans. Overall, VF that associated with loss of RyR2 function represents a distinct ventricular arrhythmia from CPVT. The activity of RyR2 influences the propensity for cardiac alternans and CPVT in an opposite manner.

description: The existing decision-making processes informing local resource-allocation mechanisms across Scotland tend to utilise historic or most recent data on life outcomes and deprivation without placing sufficient emphasis on the predictive capacity of the historic time series data. This thesis provides an analysis of spatio-temporal patterns in levels of out-of-work benefits claimant rates in relation to macroeconomic events. It aims to inform resourceallocation and service-delivery mechanisms across Scottish local authorities. The research addresses the utilisation of publicly available neighbourhood-level data sets focusing on evaluating the efficiency of local service-delivery mechanisms across Scotland. Additionally, the thesis considers the importance of spatially aggregated life outcome indicators, service user and expenditure data in the context of informing the development of non-uniform service-delivery mechanisms. The work also addresses methodological and operational issues concerned with the utilisation of small-area data across Scotland in relation to small-area deprivation and local governance.

description: ABSTRACT Since humans learnt to sing, and listen to music, sound reproduction technology has been evolving in the built environment. This began with technologies such as writing song scripts for music, and recording sound on objects such as the cylindrical and disc record, the cassette tape, and today’s digital music formats. The digitization of technology is rapidly dissolving sound reproduction into the computer through a process called dematerialization. This new stage of sound reproduction technology has presented a powerful new way to listen, share, store, purchase, and organize music in faster more efficient ways than ever before. As a result, digital files have replaced many analog technologies of the past such as cassettes, and 8-track tapes making them obsolete. This obsolescence also simultaneously amputated many of the rich experiences of playing recorded music that accompanied them. Accordingly, this project examines people’s social and phenomenological connection with technologies, and more specifically, sound reproduction technology. As this fascinating technology has evolved to become more sophisticated, what are the implications of dematerialization? Ultimately this inquiry informs an Industrial Design response with concepts exploring new form and experiences to play, and organize music in the future. Keywords: sound reproduction technology, industrial design, digitization, dematerialization, music listening, audiophile, vinyl records.

Comparison of At-Fault and No-Fault Motor Vehicle Accident Insurance in Access to Benefits for Claimants Sustaining Traumatic Brain Injury

Subjects: subject: Rehabilitation and Therapy

description: How best to compensate claimants injured in a motor vehicle accident (MVA) has been a well-debated topic for decades. Proponents of a no-fault system argue that an at-fault system is too adversarial, costly, and unresponsive in access to health care benefits, and can result in a prolonged recovery for claimants. In contrast, a no-fault system, which provides benefits to claimants regardless of fault, is viewed as more equitable and efficient and therefore fosters a better recovery. Proponents of an at-fault system, however, highlight that claimants in a no-fault system have access to only a portion of benefits they need for full restitution of their injuries to be realized. Because full restitution reflects an important societal value, and is achieved by suing an at-fault party, an at-fault system should therefore be preserved. This study compares differences between at-fault and no-fault MVA systems and between claimants with mild TBI as compared to moderate/severe TBI on measures of adversarialness, cost, responsiveness and recovery. Data from documents contained within claims files for each type of system, and by two participating MVA insurance companies in Alberta, Canada, was analysed using a mixed methods approach. Significant differences were found between: (1) at-fault and no-fault systems on measures of adversarialness and cost, both were higher in the at-fault system; and (2) mild and moderate/severe TBI groups on measures of cost and recovery, both were higher and longer, respectively, for the moderate/severe TBI group. A subsequent analysis was conducted using a four-phased claims management process: accident/fault investigation, medical/rehabilitation, claims administration, and dispute resolution phase, to identify significant key factors (and key players who participated to address these key factors) within each of these phases. The purpose was to help explain the quantitative results from the first part of the study. One of the conclusions drawn was that higher cost was significantly associated with the type of health care a claimant accessed as part of the medical/rehabilitation phase. The thesis concludes with a discussion of implications of the results as they bear on MVA claims management practices for claimants with a TBI from an MVA.

description: We use gauge-gravity duality to study the temperature dependence of the zero sound mode and the fundamental matter diffusion mode in the strongly coupled {\cal N}=4 SU(N_c) supersymmetric Yang-Mills theory with N_f {\cal N}=2 hypermultiplets in the N_c>>1, N_c>>N_f limit, which is holographically realized via the D3/D7 brane system. In the high density limit μ>>T, three regimes can be identified in the behavior of these modes, analogous to the collisionless quantum, collisionless thermal and hydrodynamic regimes of a Landau Fermi-liquid. The transitions between the three regimes are characterized by the parameters T/μand (T/μ)^2 respectively, and in each of these regimes the modes have a distinctively different temperature and momentum dependence. The collisionless-hydrodynamic transition occurs when the zero sound poles of the density-density correlator in the complex frequency plane collide on the imaginary axis to produce a hydrodynamic diffusion pole. We observe that the properties characteristic of a Landau Fermi-liquid zero sound mode are present in the D3/D7 system despite the atypical T^6/μ^3 temperature scaling of the specific heat and an apparent lack of a directly identifiable Fermi surface.

description: Nuclear structure plays a significant role on the rapid neutron capture process (r-process) since shapes evolve with the emergence of shells and sub-shells. There was some indication in neighboring nuclei that we might find examples of a new N=56 sub-shell, which may give rise to a doubly magic Se-90 nucleus. Beta-decay half lives of nuclei around Se-90 have been measured to determine if this nucleus has in fact a doubly-magic character. The fragmentation of Xe-136 beam at the National Superconducting Cyclotron Laboratory at Michigan State University was used to create a cocktail of nuclei in the A=90 region. We have measured the half lives of twenty-two nuclei near the r-process path in the A=90 region. The half lives of As-88 and Se-90 have been measured for the first time. The values were compared with theoretical predictions in the search for nuclear-deformation signatures of a N=56 sub-shell, and its possible role in the emergence of a potential doubly-magic Se-90. The impact of such hypothesis on the synthesis of heavy nuclei, particularly in the production of Sr, Y and Zr elements was investigated with a weak r-process network. The new half lives agree with results obtained from a standard global QRPA model used in r-process calculations, indicating that Se-90 has a quadrupole shape incompatible with a closed N=56 sub-shell in this region. The impact of the measured Se-90 half-life in comparison with a former theoretical predication associated with a spherical half-life on the weak-r-process is shown to be strong.
Unmapping the metropolis : urban restructuring, governmental logics, and adivasi rights in liberalizing Ahmedabad
Creators: name: Johnston, Caleb Fraser
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines the struggles and conditions of Baoris and Chharas, two adivasi(indigenous) communities living in Ahmedabad, India. It engages with the histories through which these communities were transformed into criminalized populations under the Criminal Tribes Act of 1871. As mapped Criminal Tribes, Baoris and Chharas were brought into a repressive policy apparatus designed to discipline and regulate, control and reform subaltern adivasi populations. This work documents the effects of this history in the post-colonial present. I assess Baoris and Chharas’ differentiated inclusion and exclusion within the long and troubled trajectory of India’s governmental power. Their struggles are situated within the dramatic recalibration of governmental logics and urban restructuring within the liberalizing metropolis. I consider the negotiation of rights and entitlements in a time and place wherein the Indian state is jettisoning its constitutional responsibilities to provide social welfare and democratic justice. This work argues that liberalization produces the informal to push the poor beyond the pale of legality, and suspend the possibility of accessing the technologies and categories of formal governance. I examine how the un-mapping of responsibilities, rights, and visibilities represents a central mechanism driving an emergent urban developmentalism that is reordering the city’s moral, legal and physical landscapes. Just as Baoris and Chharas’ experiences figure the greater erosion of rights and entitlements, their organizing also demonstrates how the developmental and rights-protecting apparatus of the Indian state remains a critical site of oppositional politics. I document their attempts to access and exercise technologies of governing in order to position themselves as legible populations within the classifications and categories of state power.

Sense anar més lluny, l’any 2019 es va inspirar en tres commemoracions: els 150 anys de la publicació de Vingt mille lieues sous les mers de Jules Verne (20-3-1869), els 200 anys del naixement de Narcís Monturiol (1819-1885), i els 50 anys de l’arribada de l’home a la Lluna (21-7-1969) (). El fons de divulgació científica de la BCT ha assolit un nombre de préstecs al voltant dels 40-50 llibres mensuals (i augmenta, en el millor dels casos fins al doble, en el període estival), d’un total aproximat de 1.850 llibres disponibles. L’èxit d’aquest gènere, en el nostre cas, depèn dels esforços esmerçats a reubicar el fons a l’entrada de la Sala General, a fer-lo visible entre tots els manuals de la bibliografia de curs. I, també, en el plaer de vagarejar pels prestatges i deixar-se captivar per aquell llibre que et sedueix només de tocar-lo amb la punta dels dits..., segons diuen els que ja ho han provat i continuen repetint!

description: Unfractionated heparin (UFH) use during dialysis has a narrow therapeutic window; if misjudged the dose administered by nurses based on visual assessment of post dialysis clotting and hemostasis time can cause adverse bleeding or ill effects in these patients. The purpose of this MN thesis prospective study was to examine the efficacy of a new heparin protocol. Specific research questions included: 1) Will the use of a more aggressive heparin-reduction protocol reduce the cumulative heparin dosage in chronic hemodialysis (HD) patients, 2) Is there a relationship between the dialyzer clotting scale and the ultrasound based FBV measurement, and 3) Is the visual dialyzer clotting scale used for the study reliable? Use of the study protocol significantly reduced cumulative heparin dose (p=<0.001); without affecting KT/V (F(5,55)=1.67, p=.157) or leading to extracorporeal circuit loss. Inter-rater reliability was evident between study nurse dialyzer scores (p=0.688) but there was no intra-rater reliability between study nurse and or clinical nurse educator/hemodialysis nurses.

description: Impacts of individual slow highly charged ions on alkaline earth halide and alkali halide surfaces create nano-scale surface modifications. For different materials and impact energies a wide variety of topographic alterations have been observed, ranging from regularly shaped pits to nano-hillocks. We present experimental evidence for a second threshold for defect creation supported by simulations involving the initial electronic heating and subsequent molecular dynamics. From our findings a unifying phase diagram underlying these diverse observations can be derived. By chemically etching of CaF$_2$ samples after irradiation with slow highly charged ions both above and below the potential energy threshold for hillock formation another threshold exists above which triangular pits are observed after etching. This threshold depends on both the potential and kinetic energies of the incident ion. Simulations indicate that this second threshold is associated with the formation of defect aggregates in the topmost layers of CaF$_2$.

Formation and political consequence of environmental enforcement policy : evidence from the US industries
Creators: name: Sun, Meng
Publisher: name: University of British Columbia
Year: 2010

description: This thesis investigates the determinants and political consequences of environmental enforcement policy. Three related issues are addressed using the U.S. manufacturing data at the industry level. In Chapter Two, I estimate the elasticity of the violation rate with respect to the inspection rate for the manufacturing industries. This elasticity reflects the power of monitoring to alter an industry's violation status. I conduct an estimation of the relationship between the violation rate and the inspection rate at the industry level, but the specification is based on an individual firm's dichotomous choice in a logit model. The inspection rate is instrumented with the average of the inspection rates across the other industries that belong to the same sector to deal with the endogeneity problem. I find a substantial variation in the elasticity of the violation rate across industries. Chapter Three addresses how the inspection rate is determined by the elasticity of the violation rate when the enforcement agency is constrained with a hard monitoring budget. Given the limited monitoring resources, an enforcement agency targets industries where inspections are more likely to be effective in reducing violations to reduce inefficiency, all else equal. Empirical results confirm the positive effect from the absolute elasticity on the inspection rate. But the magnitude of this effect is conditional on the pollutants' damage level to the environment. In Chapter Four, I focus on the political consequence of the enforcement policy. I employ the campaign contribution presented to the Congress exclusively for environmental issues (EPC) to measure the environmental political activity. The variation of EPC across industries is explained by the enforcement policy stringency. Although the EPC presented to the Congress is targeted directly on environmental regulation rather than the enforcement policy, a stricter enforcement policy increases the marginal benefit from contributing the congress for relaxing the regulation. Empirically, I use the elasticity of the violation rate to isolate the effect of the enforcement policy on EPC. An industry with a larger elasticity of the violation rate is more likely to face a higher inspection rate, it therefore is more likely to engage in the political activity.
Analytic Spectra of CMB Anisotropies and Polarization Generated by Scalar Perturbations in Synchronous Gauge

description: We present a detailed analytical calculation of CMB temperature anisotropies α_k and polarization β_k generated by scalar metric perturbations in synchronous gauge, parallel to our previous work with RGW as a generating source. This is realized primarily by an analytic time-integration of Boltzmann's equation, yielding the closed forms of α_k and β_k. Approximations, such as the tight-coupling approximation for photons a prior to the recombination and the long wavelength limit for scalar perturbations are used. The residual gauge modes in scalar perturbations are analyzed and a proper joining condition of scalar perturbations at the radiation-matter equality is chosen, ensuring the continuity of energy perturbation. The resulting analytic expressions of the multipole moments of polarization a^E_l, and of temperature anisotropies a^T_l are explicit functions of the scalar perturbations, recombination time, recombination width, photon free streaming damping factor, baryon fraction, initial amplitude, primordial scalar spectral index, and the running index. These results show that a longer recombination width yields higher amplitudes of polarization on large scales and more damping on small scales, and that a late recombination time shifts the peaks of C^{XX'}_l to larger angular scales. The analytic spectra C^{XX'}_l agree with the numerical ones and with those observed by WMAP on large scales (l \lesssim 500), but deviate considerably from the numerical results on smaller scales, showing the limitations of our approximate analytic calculations. Several possible improvements are pointed out for further studies.

Some Problems on Graphs and Arrangements of Convex Bodies

description: Arrangements of convex bodies are ubiquitous in discrete geometry. Covering and packing problems are two major classes of problems arising from these arrangements. This thesis makes contributions to some open questions on covering a convex body by its homothetic copies and packings of translates of a convex body. The packings we study lead to the notion of a contact graph, a tool used by mathematicians, material scientists and physicists while investigating these packings. This brings a combinatorial flavour to this thesis and leads to the algorithmic question of generating graphs and hypergraphs with desired properties. We introduce the covering index of a convex body as a measure of how economically the body can be covered by a relatively few smaller positive homothetic copies. Determining the covering index can be thought of as a quantitative version of the sixty-year old Covering Conjecture in discrete and convex geometry. We prove several interesting properties of the covering index, compute its values for large classes of convex bodies and use it to devise an approach to attack the Covering Conjecture. We then consider the problem of determining the separable Hadwiger number of a smooth convex domain and the maximum contact numbers of totally separable translative packings of a smooth strictly convex domain. Both these questions have links with crystallography and self-assembly of material particles, and are completely solved here. Moreover, we show that for smooth Radon domains the extremal packings always lie on special kinds of lattices and characterize the underlying contact graphs. Next, we fully address the algorithmic questions of constructing tournaments from their imbalance sets and hypertournaments from their score sequences. The former relates to the Equal-Sum Subsets problem from computer science, while the latter is a special instance of the degree sequence problem that asks for the generation of all graphs or hypergraphs in some large class that have the same degree sequence. We characterize imbalance sets of tournaments, give an algorithm to generate tournaments from their imbalance sets and define a rapidly mixing Markov chain that uniformly samples all hypertournaments with a given score sequence.

description: En aquests moments tan elevats d’incertesa la literatura és capaç de proporcionar-nos models d’explicació del món i, alhora, i sobretot, de nosaltres mateixos. Per tant, d’actuació. Per això, més que mai, cal donar-hi cabuda. La literatura ens pot eixamplar el món, ens pot fer entendre millor la nostra vida, a través d’altres vides. Llegir els clàssics és un valor segur. Per això, ja fa més de deu anys una colla de centres literaris aglutinats dins la xarxa de patrimoni literari català, Espais Escrits , va decidir posar en marxa el Mapa Literari Català , un web que geolocalitza la literatura catalana al món. La literatura dels nostres clàssics catalans al món.
