Self-understanding and identity : the experience of adolescents at risk for Huntington’s disease
Creators: name: Easton, Jessica L.
Publisher: name: University of British Columbia
Year: 2009

description: Adolescence is a time when individuals begin to explore and examine psychological characteristics of the self in order to discover who they really are and how they fit in the social world in which they live. It is during this time of self-exploration that adolescents at risk for Huntington's Disease often learn of their risk status and witness the debilitating symptoms of the disease in their parents. Huntington Disease (HD) is an autosomal dominant neuropsychiatric disorder characterized by mid-life onset, involuntary movements, cognitive impairment, and depression. This dissertation investigated how adolescents experience living in a family with Huntington's Disease and therefore at risk for Huntington's Disease, and how this impacts their self-understanding and self-identity. The method of inquiry was based on a phenomenological approach. In-depth interviews were conducted with each of the adolescents. The data were analyzed using Van Manen's (1980) and Cochran and Claspell's (1987) format, resulting in an extraction of three themes. These themes are: (1) Naming the Legacy: Understanding and Misunderstanding; (2) Experiencing the Legacy: Huntington's Disease in Relation to Relationships; and (3) Integrating the Legacy: At the Crossroads of Self and Future Self. The analysis emphasizes that the at-risk adolescents' exploration of self-identity and future self was an individual process influenced by the cognitive, developmental, and socio-cultural contexts of the adolescents' lives. The process of learning about Huntington's Disease occurred through intuition and practical and experiential learning. The adolescents found support outside their family through friends and adult mentors. They engaged in complicated coping strategies and demonstrated a capacity for decision-making that displayed maturity beyond what would be expected for their age group. These findings led to specific recommendations for theory, research, and clinical practice in the area of the adolescent experience of HD. The research underscores the need for healthcare professionals to re-evaluate their view of adolescent autonomy and capacity for decision-making.

description: High-throughput atomistic simulations reveal the unique effect of solute atoms on twin variant selection in Mg-Al alloys. Twin embryos first undergo a stochastic incubation stage when embryos choose which twin variant to adopt, and then a deterministic growth stage when embryos expand without changing the selected twin variant. An increase in Al composition promotes the stochastic incubation behavior on the atomic level due to nucleation and pinning of interfacial disconnections. At compositions above a critical value, disconnection pinning results in multiple twin variant selection.
The 2002 Outburst of the Black-Hole X-ray Binary 4U 1543-47: Optical and Infrared Light Curves

description: We have obtained simultaneous optical and near infrared observations of 4U 1543-47 during its 2002 outburst. The most striking feature of the outburst light curve is the secondary maximum which appears after the object transitions into the low-hard state. This secondary maximum is much stronger in the infrared bands than optical. We suggest that the origin of the secondary maximum flux may be synchrotron radiation associated with a jet. Close infrared monitoring may lead to reliable triggers for simultaneous multiwavelength campaigns to study jet formation processes.

Semiclassical and quantum Liouville theory

Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We develop a functional integral approach to quantum Liouville field theory completely independent of the hamiltonian approach. To this end on the sphere topology we solve the Riemann-Hilbert problem for three singularities of finite strength and a fourth one infinitesimal, by determining perturbatively the Poincare' accessory parameters. This provides the semiclassical four point vertex function with three finite charges and a fourth infinitesimal. Some of the results are extended to the case of n finite charges and m infinitesimal. With the same technique we compute the exact Green function on the sphere on the background of three finite singularities. Turning to the full quantum problem we address the calculation of the quantum determinant on the background of three finite charges and of the further perturbative corrections. The zeta function regularization provides a theory which is not invariant under local conformal transformations. Instead by employing a regularization suggested in the case of the pseudosphere by Zamolodchikov and Zamolodchikov we obtain the correct quantum conformal dimensions from the one loop calculation and we show explicitly that the two loop corrections do not change such dimensions. We then apply the method to the case of the pseudosphere with one finite singularity and compute the exact value for the quantum determinant. Such results are compared to those of the conformal bootstrap approach finding complete agreement.

description: Recent observations, reported by Warner and Woudt, of Dwarf Nova Oscillations (DNOs) exhibiting frequency drift, period doubling, and 1:2:3 harmonic structure, can be understood as disc oscillations that are excited by perturbations at the spin frequency of the white dwarf or of its equatorial layers. Similar quasi-periodic disc oscillations in black hole low-mass X-ray binary (LMXB) transients in a 2:3 frequency ratio show no evidence of frequency drift and correspond to two separate modes of disc oscillation excited by an internal resonance. Just as no effects of general relativity play a role in white dwarf DNOs, no stellar surface or magnetic field effects need be invoked to explain the black hole QPOs.

The implications of the twisted Poincaré symmetry on QFT on such a space-time is briefly discussed. The presence of the twisted symmetry gives justification to all the previous treatments within NC QFT using Lorentz invariant quantities and the representations of the usual Poincaré symmetry.

A Mixed-Methods Analysis of Neighborhood Domestic Violence Resources and Intimate Partner Homicide
Creators: name: Harper, Shannon B
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: This concurrent triangulation mixed-methods study involves a neighborhood analysis of the relationship between domestic violence resources and intimate partner homicide (IPH) trajectories. As part of the mixed-methods study, the quantitative method identifies neighborhood-level pooled and sex-specific IPH trajectory groups; and examines how domestic violence resources, declining domesticity, female economic status relative to male economic status, and social disorganization affect membership in the identified trajectories. Results reveal multiple distinct trajectories of varying shapes and that most domestic violence resources are associated with decreased likelihood of higher trajectory group membership. The qualitative study fills methodological gaps present in the quantitative study. Specifically, the quantitative study examines how the availability of domestic violence resources influence neighborhood IPH trajectories, while the qualitative study explores whether women are actually accessing those resources and how they make decisions to seek assistance. Results reveal that severely abused women’s help-seeking decisions take shape within the context of abuse (i.e., patterns of abuse and individual life circumstances) they are experiencing and in relation to personal perceptions of homicide risk. The qualitative study demonstrates that severely abused women experience unique patterns of help-seeking where they travel along a continuum of delaying and hastening outreach. Collectively, the qualitative findings help to deconstruct women’s complex help-seeking contemplation processes and resultant help-seeking decisions through which the decreased neighborhood homicide risk outcomes identified in the quantitative study are realized.

description: Competition has been introduced in the electricity markets with the goal of reducing prices and improving efficiency. The basic idea which stays behind this choice is that, in competitive markets, a greater quantity of the good is exchanged at a lower and a lower price, leading to higher market efficiency. Electricity markets are pretty different from other commodities mainly due to the physical constraints related to the network structure that may impact the market performance. The network structure of the system on which the economic transactions need to be undertaken poses strict physical and operational constraints. Strategic interactions among producers that game the market with the objective of maximizing their producer surplus must be taken into account when modeling competitive electricity markets. The physical constraints, specific of the electricity markets, provide additional opportunity of gaming to the market players. Game theory provides a tool to model such a context. This paper discussed the application of game theory to physical constrained electricity markets with the goal of providing tools for assessing the market performance and pinpointing the critical network constraints that may impact the market efficiency. The basic models of game theory specifically designed to represent the electricity markets will be presented. IEEE30 bus test system of the constrained electricity market will be discussed to show the network impacts on the market performances in presence of strategic bidding behavior of the producers.

description: One of the challenges in virtual environments is the difficulty users have in interacting with these increasingly complex systems. Ultimately, endowing machines with the ability to perceive users emotions will enable a more intuitive and reliable interaction. Consequently, using the electroencephalogram as a bio-signal sensor, the affective state of a user can be modelled and subsequently utilised in order to achieve a system that can recognise and react to the user's emotions. This paper investigates features extracted from electroencephalogram signals for the purpose of affective state modelling based on Russell's Circumplex Model. Investigations are presented that aim to provide the foundation for future work in modelling user affect to enhance interaction experience in virtual environments. The DEAP dataset was used within this work, along with a Support Vector Machine and Random Forest, which yielded reasonable classification accuracies for Valence and Arousal using feature vectors based on statistical measurements and band power from the ź, \b{eta}, ź, and źź waves and High Order Crossing of the EEG signal.

description: Intriguing phenomena such as subrecoil laser cooling of atoms, or aging phenomenon in glasses, have in common that the systems considered do not reach a steady-state during the experiments, although the experimental time scales are very large compared to the microscopic ones. We revisit some standard models describing these phenomena, and reformulate them in a unified framework in terms of lifetimes of the microscopic states of the system. A universal dynamical mechanism emerges, leading to a generic time-dependent distribution of lifetimes, independently of the physical situation considered.

Light deflection in Weyl gravity: constraints on the linear parameter

description: Light deflection offers an unbiased test of Weyl's gravity since no assumption on the conformal factor needs to be made. In this second paper of our series ``Light deflection in Weyl gravity'', we analyze the constraints imposed by light deflection experiments on the linear parameter of Weyl's theory. Regarding solar system experiments, the recent CASSINI Doppler measurements are used to infer an upper bound, $\sim 10^{-19} $m$^{-1}$, on the absolute value of the above Weyl parameter. In non-solar system experiments, a condition for unbound orbits together with gravitational mirage observations enable us to further constrain the allowed negative range of the Weyl parameter to $\sim -10^{-31} $m$^{-1}$. We show that the characteristics of the light curve in microlensing or gravitational mirages, deduced from the lens equation, cannot be recast into the General Relativistic predictions by a simple rescaling of the deflector mass or of the ring radius. However, the corrective factor, which depends on the Weyl parameter value and on the lensing configuration, is small, even perhaps negligible, owing to the upper bound inferred on the absolute value of a negative Weyl parameter. A statistical study on observed lensing systems is required to settle the question. Our Weyl parameter range is more reliable than the single value derived by Mannheim and Kazanas from fits to galactic rotation curves, $\sim +10^{-26}\ $m$^{-1}$. Indeed, the latter, although consistent with our bounds, is biased by the choice of a specific conformal factor.

description: Ultraviolet (UV) diode lasers are widely used in many photonics applications. But their frequency stabilization schemes are not as mature as frequency-doubling lasers, mainly due to some limitations in the UV spectral region. Here we developed a high-performance UV frequency stabilization technique implemented directly on UV diode lasers by combining the dichroic atomic vapor laser lock and the resonant transfer cavity lock. As an example, we demonstrate a stable locking with frequency standard deviations of approximately 200 KHz and 300 KHz for 399nm and 370nm diode lasers in 20 minutes. We achieve a long-term frequency drift of no more than 1 MHz for the target 370nm laser within an hour, which was further verified with fluorescence counts rates of a single trapped $^{171}$Yb$^+$ ion. We also find strong linear correlations between lock points and environmental factors such as temperature and atmospheric pressure.

description: We have extended Monte Carlo simulations of hopping transport in completely disordered 2D conductors to the process of external charge relaxation. In this situation, a conductor of area $L \times W$ shunts an external capacitor $C$ with initial charge $Q_i$. At low temperatures, the charge relaxation process stops at some "residual" charge value corresponding to the effective threshold of the Coulomb blockade of hopping. We have calculated the r.m.s$.$ value $Q_R$ of the residual charge for a statistical ensemble of capacitor-shunting conductors with random distribution of localized sites in space and energy and random $Q_i$, as a function of macroscopic parameters of the system. Rather unexpectedly, $Q_{R}$ has turned out to depend only on some parameter combination: $X_0 \equiv L W ν_0 e^2/C$ for negligible Coulomb interaction and $X_χ \equiv LW κ^2/C^{2}$ for substantial interaction. (Here $ν_0$ is the seed density of localized states, while $κ$ is the dielectric constant.) For sufficiently large conductors, both functions $Q_{R}/e =F(X)$ follow the power law $F(X)=DX^{-β}$, but with different exponents: $β= 0.41 \pm 0.01$ for negligible and $β= 0.28 \pm 0.01$ for significant Coulomb interaction. We have been able to derive this law analytically for the former (most practical) case, and also explain the scaling (but not the exact value of the exponent) for the latter case. In conclusion, we discuss possible applications of the sub-electron charge transfer for "grounding" random background charge in single-electron devices.

description: We investigate spin- and velocity-dependent contributions to the gravitational inter-particle potential. The methodology adopted here is based on the expansion of the effective action in terms of form factors encoding quantum corrections. Restricting ourselves to corrections up to the level of the graviton propagator, we compute, in terms of general form factors, the non-relativistic gravitational potential associated with the scattering of spin-0 and -1/2 particles. We discuss comparative aspects concerning different types of scattered particles and we also establish some comparisons with the case of electromagnetic potentials. Moreover, we apply our results to explicit examples of form factors based on non-perturbative approaches for quantum gravity. Finally, the cancellation of Newtonian singularity is analysed in the presence of terms beyond the monopole-monopole sector.

To examine this tradeoff, this study outlines a mathematical model to study the effectiveness of traps and the cost of treatment. The empirical results presented in this study indicate that additional parameterization efforts are needed.

Becoming photographs : aesthetics of immanence
Creators: name: James, Joy
Publisher: name: University of British Columbia
Year: 2009

description: The "eventfulness" of the photograph—the force of its becoming and its continued potentiality—is the primary concern of this dissertation. My work is informed by recent philosophical discussions regarding processes of thinking and seeing, and by the multiple histories and theories of photography that have arisen since its invention as a reproductive technology. I work with a small selection of photographs, all of them portraits of one sort or another, dating from the end of the nineteenth century through the first few decades of the twentieth century, and produced in diverse geographical, cultural and political settings. From the moment when I first encountered each of these photographs, they appeared to exceed any signification that can be attributed to them by current theories of photography. In the course of my analysis, I argue that this is because all of the images are "atypical" in a way that, according to Gilles Deleuze and Felix Guattari in their interpretation of minor literatures, heralds potentiality. These photographs were implicated in political economies of transformation. I propose that, at the time they were made, all of these pictures were futural: the stuff of collective becomings. The images present as multiples: how they were seen was dependent on who was doing the looking. The "atypical expression" that I claim for each photograph emerges only at distinctly marked sites and under exceptional conditions of "seeing." Here my findings intersect with, and modulate, concepts of "seeing photographically" that have recently been put forward by a number of scholars, most notably by Celia Lury in "Prosthetic Culture: Photography, Memory and Identity" (1998). Deleuze and Guattari both did and did not extend their understanding of atypical expression to include photographs. Whereas, in "A Thousand Plateaus: Capitalism and Schizophrenia" (1987), they suggest that the photograph is closer to a "tracing" than to a "map" (21), in "Kafka: Toward a Minor Literature", they show the ways in which that author figures photographs as maps of the most potent kind I believe that Deleuze and Guattari's theory of expression, as most recently elaborated by Brian Massumi in his introduction to "A Shock to Thought: Expression after Deleuze and Guattari" (2002), can be productively engaged to revitalize our perception of what these photographs did. An investigation of how these photographs functioned is important for the way in which it opens on to another tremor in the shock to thinking/seeing, the move into virtual reality and digital imaging.

The two topics are linked with a description of how information technology (IT) has enabled the development of the fuel ethanol franchise and a discussion of how IT is changing the very nature of biofuel operations.
Connecting the exterior gravitational field with the energy momentum tensor of axially symmetric compact objects

description: A method to construct interior axially symmetric metrics that appropriately match with any vacuum solution of the Weyl family is developed in Hernandez-Pastora etal. (Class Quantum Gravity 33:235005, 2016). It was shown,for the case of some vacuum solutions, that the simplestsolution for the interior metric leads to sources with well behaved energy conditions. Now, we integrate the field equa-tions to obtain the interior metric functions in terms of theanisotropies and pressures of the source. As well, the compatible equations of state for these global models are calculated. The interior metric and the suitable energy momentum tensor describing the source are constructed in terms of the exterior metric functions. At the boundary of the compact object,the behaviour of a pressure Tm, defined from the energy momentum tensor, is shown to be related with the exterior gravitational field. This fact allows us to explore the differences arising at the matter distribution when the sphericalsymmetry of the global metric is dropped. Finally, an equation derived from the matching conditions is obtained whichallows us to calculate the Weyl coefficients of the exteriormetric as source integrals. Hence the Relativistic MultipoleMoments of the global model can be expressed in terms ofthe matter distribution of the source.

description: This study examines the rapidly expanding biofuels industry and identifies challenges for producer-owned biofuel projects. The U.S. ethanol industry has been growing rapidly, and biodiesel production is poised for similar growth. Producer involvement is driven by the desire to add value to farm commodities and the impact of biofuel projects on local grain prices. Local state and federal incentives have also stimulated producer interest. The long-run profitability of biofuel projects is driven by feedstock availability, access to market centers for biofuels, access to markets for coproducts, and utility costs and availability. The rapidly increasing size and scale of ethanol and biodiesel plants make it difficult for producers to fund these projects. Additionally, the development and adoption of new non-grain biofuel technologies may negate some comparative advantages of producers, such as feedstock cost and availability. The geographic expansion of biofuel projects into grain deficit regions will also create additional challenges.

description: We devise an iterative scheme for numerically calculating dynamical two-point correlation functions in integrable many-body systems, in the Eulerian scaling limit. Expressions for these were originally derived in Ref. [1] by combining the fluctuation-dissipation principle with generalized hydrodynamics. Crucially, the scheme is able to address non-stationary, inhomogeneous situations, when motion occurs at the Euler-scale of hydrodynamics. In such situations, in interacting systems, the simple correlations due to fluid modes propagating with the flow receive subtle corrections, which we test. Using our scheme, we study the spreading of correlations in several integrable models from inhomogeneous initial states. For the classical hard-rod model we compare our results with Monte-Carlo simulations and observe excellent agreement at long time-scales, thus providing the first demonstration of validity for the expressions derived in Ref. [1]. We also observe the onset of the Euler-scale limit for the dynamical correlations.

description: The income capitalization approach is used, based on expenditure and nonmarket values collected from travel-cost and contingent valuation methodologies, to measure the feasibility of running a self-sustaining recreational site in coastal Louisiana. Through Internet and intercept surveys, a total of 2,696 respondents, 88% of them anglers, provided information on economic expenditures, destination preferences, and preferences for specific site amenities regarding Elmer's Island. The purchase and subsequent opening of the area to the public were found to be self-sustaining even when considering conservative economic estimates.

description: We report on experiments to measure the temporal and spatial evolution of packing arrangements of anisotropic and weakly confined granular material, using high-resolution $γ$-ray adsorption. In these experiments, the particle configurations start from an initially disordered, low-packing-fraction state and under vertical solicitations evolve to a dense state. We find that the packing fraction evolution is slowed by the grain anisotropy but, as for spherically shaped grains, can be well fitted by a stretched exponential. For a given type of grains, the characteristic times of relaxation and of convection are found to be of the same order of magnitude. On the contrary compaction mechanisms in the media strongly depend on the grain anisotropy.

description: This study summarizes research on farm-, local-, regional-, and macro-level economic effects of ethanol production. Given current production levels, the ethanol production industry annually employees approximately 3,500 workers, pays out nearly $132 million in worker salaries, generates over $110 million in local taxes, and takes in some $2 billion in government incentive payments. Projections for a 60 million gallon per year ethanol plant indicate an annual increase in corn usage of 21 million bushels, a one-time capitalization of $75 million, an increase in local corn prices between $0.06/bushel and $0.12/bushel, a 54 direct and 210 indirect jobs created, and increase in local tax revenues of $1.2 million, a decrease in federal commodity program outlays of $30 million, and an increase in ethanol production incentives (federal only) of around $30.5 million.

description: Before pandemic the world economy had a pre-crisis situation which was characterized by unprecedented imbalances in the global financial and economic system, the lack of growth in world GDP, which posed a real threat to the world economic order. Almost all global analysts predicted a global economic crisis at the end of 2019. For the first time since time immemorial, bank interest rates in all countries have dropped to unprecedented low levels. Often interest rates were 0% or even negative. The EU’s financial system has been so disfigured by the VAT tax that fraud with this tax has reached a scale far exceeding hundreds of billions EUR and in fact got out of control of the authorities.

description: On the basis of the separated form-factors model, parameters of the polydispersed unilamellar DMPC vesicle population are analyzed. The neutron scattering length density across the membrane is simulated on the basis of fluctuated model of lipid bilayer. The hydration of vesicle is described by sigmoid distribution function of the water molecules. The results of fitting of the experimental data obtained at the small angle spectrometer SANS-I, PSI (Switzerland) are: average vesicle radius 272 angstrom, polydispersity of the radius 27%, membrane thickness 50.6 angstrom, thickness of hydrocarbon chain region 21.4 angstrom, number of water molecules located per lipid molecule 13, and DMPC surface area 59. The calculated water distribution function across the bilayer directly explains why lipid membrane is easy penetrated by water molecules.

description: In general, linear response theory expresses the relation between a driving and a physical system's response only to first order in perturbation theory. In the context of charge transport, this is the linear relation between current and electromotive force expressed in Ohm's law. We show here that, in the case of the quantum Hall effect, all higher order corrections vanish. We prove this in a fully interacting setting and without flux averaging.

Staggered-flux state for rectangular-lattice spin 1/2 Heisenberg antiferromagnet

description: We investigate the spin-1/2 Heisenberg model on a rectangular lattice, using the Gutzwiller projected variational wave function known as the staggered flux state. Using Monte Carlo techniques, the variational parameters and static spin-structure factor for different coupling anisotropies $γ=J_y/J_x$ are calculated. We observe a gradual evolution of the ground state energy towards a value which is very close to the 1D estimate provided by the Bethe ansatz and a good agreement between the finite size scaling of the energies. The spin-spin correlation functions exhibit a power-law decay with varying exponents for different anisotropies. Though the lack of Néel order makes the staggered flux state energetically unfavorable in the symmetric case $γ=1$, it appears to capture the essence of the system close to 1D. Hence we believe that the staggered flux state provides an interesting starting point to explore the crossover from quantum disordered chains to the Néel ordered 2D square lattices.
XMM-Newton observation of the double pulsar system J0737-3039

description: We report on a 50 ksec XMM-Newton observation of the double pulsar system J0737-3039 performed on April 2004. We present results of the spectral analysis of these data combined with the much shorter Chandra pointing performed on January 2004. Black body emission with effective temperature of 0.20^{+0.02}_{-0.02} keV (90% confidence level) and emission radius 75^{+30}_{-9} m for a distance of 0.5 kpc (implying a 0.5-10 keV luminosity \~6x10^{29} erg/s) is a viable interpretation, calling for a stream of particles accelerated in the magnetosphere of PSR J0737-3039A and depositing their kinetic energy in the magnetic polar cap of PSR J0737-3039A or of the companion PSR J0737-3039B. A single power-law emission model implies a very steep photon index Gamma=4.2^{+2.1}_{-1.2} and a suspiciously high hydrogen column density, whereas a photon index Gamma=2 does not provide an adequate description of the XMM-Newton and Chandra data. A two component model (a black body plus a power-law with Gamma=2) is statistically acceptable, but the additional power-law component is not required by the data.
