description: Studies in the area of health economics and public health have shown that low socioeconomic status (SES) and poverty are related to lower levels of health. Attempts to explain these differences have often made reference to the observation that poor health behaviours cluster in low SES respectively poverty groups. However, relatively little attention has been paid to the defining concept of SES and its appropriate measurement. Therefore data from the German Socio-Economic Panel are used to analyse the relationship between two multidimensional measurements to describe a) poverty respectively b) a low SES and health behaviour, including dietary behaviour, weight status and health behaviour in general. This study shows that both multidimensional indicators allow identifying an inverse relationship between low SES respectively poverty and several types of health behaviour. However, comparing both indicators it is evident that individuals may be affected by poverty in different ways which has various effects on their health behaviour. Additionally, future research should focus not only on multidimensional poverty measurements but also on dynamic effects.

description: We discuss a family of Vlasov-Maxwell equilibrium distribution functions for current sheet equilibria that are intermediate cases between the Harris sheet and the force-free (or modified) Harris sheet. These equilibrium distribution functions have potential applications to space and astrophysical plasmas. The existence of these distribution function had been briefly discussed in by Harrison and Neukirch 2009, but here it is shown that their approach runs into problems in the limit where the guide field goes to zero. The nature of this problem will be discussed and an alternative approach will be suggested that avoids the problem. This is achieved by considering a slight variation of the magnetic field profile, which allows a smooth transition between the Harris and force-free Harris sheet cases.

description: Heavy withdrawals from the most dependable source of groundwater in the Texas Panhandle, the Ogallala Aquifer, create an impending need for implementing water conservation policies. This study evaluates the policy option of multi-year water allocation coupled with water use restriction in four water deficit counties of Castro, Deafsmith, Parmer and Swisher over a sixty year planning horizon. Results indicate that the water use in the study area declines with progressive restriction rates accompanied by a substantial decrease in the net present value of net returns over sixty years and therefore it is important to analyze the socio-economic effects of implementing such a policy alternative.

description: Terahertz (THz) radiation, spanning from 0.3 to 3x10^12 Hz, fills the crucial gap between the microwave and infrared spectral range. THz technology has found applications in various fields, from imaging and sensing to telecommunication and biosensing. However, the full potential of these applications is often hindered by the need for precise control and manipulation of the frequency and polarization state, which typically requires external THz modulators. Here, we demonstrate a hybrid THz source that overcomes this limitation. Our device consists of two THz emitters integrated into one single device, enabling pulse shaping and chirality control of the emitted radiation without additional external components. The two sources are a spintronic emitter and a semiconductor photoconductive antenna (PCA). Using a combination of dual-wavelength excitation, allowing for control of the relative time delay between the two laser excitation pulses, and tuning external parameters for each emitter (i.e., biasing voltage for the PCA and magnetic field for the spintronic THz emitter) enables precise control of the mixing of the two signals and results in frequency, polarization, and chirality control of the overall THz radiation. This on-chip hybrid emitter provides an essential platform for engineered THz radiation with wide-ranging potential applications.

description: We address the problem of simulating efficiently from the posterior distribution over the parameters of a particular class of nonlinear regression models using a Langevin-Metropolis sampler. It is shown that as the number N of parameters increases, the proposal variance must scale as N{-1/3} in order to converge to a diffusion. This generalizes previous results of Roberts and Rosenthal [J. R. Stat. Soc. Ser. B Stat. Methodol. 60 (1998) 255-268] for the i.i.d. case, showing the robustness of their analysis.
Comment on the Origin of the Supermassive Black Hole

Subjects: subject: Astrophysics (astro-ph)

description: We give the comment why the supermassive black hole exists at the center of almost all galaxies. We consider the origin of the supermassive black hole from the point of view of the density of the matter. If the density of the matter is fixed and such matter can come together by the gravitational attraction, such stellar object eventually becomes the black hole. If the density of the matter is that of the atom, such matter naturally comes together to form the black hole by the gravitational attraction. This is expected to be the process to form the supermassive black hole. In this way, we can understand that there exists supermassive black hole at the center of almost all galaxies, because there is no delicate process to evolve into the black hole.

title: Scottish documentary photography and the archive : George M. Cowie, Franki Raffles and Document Scotland in the University of St Andrews Photographic Collection
Creators: name: Heeley, Lydia Isabel
Publisher: name: University of St Andrews
Year: 2019

description: Scottish documentary photography has a significant historical connection with St Andrews. The St Andrews Photographic Collection upholds this link by preserving historic and contemporary collections. This thesis investigates how the collection’s acquisitions of photographic work place the photographer within the tradition of Scottish documentary photography. Three case studies are examined, the George M. Cowie collection of photojournalism, the Franki Raffles collection, and the collection of the photographic collective, Document Scotland. The ways in which the archive preserves and promotes this material are examined in a number of ways. Firstly, how the organisation of the material affects the sense of the photographers’ working practice and authorship of the material. Secondly, how the materiality of the collections is used in a way that further informs the photographers’ body of work. Thirdly, how the archive’s presentation of this material can be utilised by researchers and institutions to promote and re-interpret this work. Finally, these aspects are considered in terms of positioning the discussed photographers within the legacy of Scottish documentary photography.

description: In this paper we study the impact of augmenting spoken language corpora with domain-specific synthetic samples for the purpose of training a speech recognition system. Using both a conventional neural TTS system and a zero-shot one with voice cloning ability we generate speech corpora that vary in the number of voices. We compare speech recognition models trained with addition of different amounts of synthetic data generated using these two methods with a baseline model trained solely on voice recordings. We show that while the quality of voice-cloned dataset is lower, its increased multivoiceity makes it much more effective than the one with only a few voices synthesized with the use of a conventional neural TTS system. Furthermore, our experiments indicate that using low variability synthetic speech quickly leads to saturation in the quality of the ASR whereas high variability speech provides improvement even when increasing total amount of data used for training by 30%.

description: We develop a fully-coupled, fully-implicit approach for phase-field modeling of solidification in metals and alloys. Predictive simulation of solidification in pure metals and metal alloys remains a significant challenge in the field of materials science, as microstructure formation during the solidification process plays a critical role in the properties and performance of the solid material. Our simulation approach consists of a finite element spatial discretization of the fully-coupled nonlinear system of partial differential equations at the microscale, which is treated implicitly in time with a preconditioned Jacobian-free Newton-Krylov method. The approach allows time steps larger than those restricted by the traditional explicit CFL limit and is algorithmically scalable as well as efficient due to an effective preconditioning strategy based on algebraic multigrid and block factorization. We implement this approach in the open-source Tusas framework, which is a general, flexible tool developed in C++ for solving coupled systems of nonlinear partial differential equations. The performance of our approach is analyzed in terms of algorithmic scalability and efficiency, while the computational performance of Tusas is presented in terms of parallel scalability and efficiency on emerging heterogeneous architectures. We demonstrate that modern algorithms, discretizations, and computational science, and heterogeneous hardware provide a robust route for predictive phase-field simulation of microstructure evolution during additive manufacturing.

description: After a brief introduction to crystalline organic superconductors and metals, we shall describe two recently-observed exotic phases that occur only in high magnetic fields. The first involves measurements of the non-linear electrical resistance of single crystals of the charge-density-wave (CDW) system (Per)$_2$Au(mnt)$_2$ in static magnetic fields of up to 45 T and temperatures as low as 25 mK. The presence of a fully gapped CDW state with typical CDW electrodynamics at fields higher that the Pauli paramagnetic limit of 34 T suggests the existence of a modulated CDW phase analogous to the Fulde-Ferrell-Larkin-Ovchinnikov state. Secondly, measurements of the Hall potential of single crystals of $α$-(BEDT-TTF)$_2$KHg(SCN)$_4$, made using a variant of the Corbino geometry in quasistatic magnetic fields, show persistent current effects that are similar to those observed in conventional superconductors. The longevity of the currents, large Hall angle, flux quantization and confinement of the reactive component of the Hall potential to the edge of the sample are all consistent with the realization of a new state of matter in CDW systems with significant orbital quantization effects in strong magnetic fields.

description: Planets around young stars are thought to undergo atmospheric evaporation due to the high magnetic activity of the host stars. Here we report on X-ray observations of V1298 Tau, a young star with four transiting exoplanets. We use X-ray observations of the host star with Chandra and ROSAT to measure the current high-energy irradiation level of the planets, and employ a model for the stellar activity evolution together with exoplanetary mass loss to estimate the possible evolution of the planets. We find that V1298 Tau is X-ray bright with $\log L_X$ [erg/s] $=30.1$ and has a mean coronal temperature of $\approx 9$ MK. This places the star amongst the more X-ray luminous ones at this stellar age. We estimate the radiation-driven mass loss of the exoplanets, and find that it depends sensitively on the possible evolutionary spin-down tracks of the star as well as on the current planetary densities. Assuming the planets are of low density due to their youth, we find that the innermost two planets can lose significant parts of their gaseous envelopes, and could be evaporated down to their rocky cores depending on the stellar spin evolution. However, if the planets are heavier and follow the mass-radius relation of older planets, then even in the highest XUV irradiation scenario none of the planets is expected to cross the radius gap into the rocky regime until the system reaches an age of 5 Gyr.

description: In this work we revisit the problem of a Majorana box qubit (MBQ) readout by a point-contact (PC) detector. The logic states of the MBQ are associated with the combined fermion parities of the MBQ and its tunnel-coupled quantum dot, which is measured by a PC detector. Beyond the existing studies on limiting bias voltage regimes, we analyze the steady-state current and the current power spectrum across all bias voltages. Our results indicate that the MBQ readout via the parity-dependent detector current is effective only at low bias voltage regime and requires the dot energy level to be off-resonance with the Majorana qubit. In contrast, the current power spectrum allows MBQ readout through the parity-dependent Rabi oscillation peak signals for arbitrary bias voltages, without restrictions on the dot energy level. Particularly, with focus on the MBQ measurement visibility, we analyze the peak-to-pedestal ratio for each characteristic peak (associated with each logic state of the qubit) and the signal-to-noise ratio of the two peaks. By examining these two metrics, we identify the optimal bias voltage window for the PC detector at low temperature limit.

Prime symmetric divisor functions
Creators: name: Woodford, Roger
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis, we study a new class of divisor-related functions: the prime symmetric functions. The elementary prime symmetric functions are denned on the nonnegative integers. They take the values of the elementary symmetric functions applied to the multi-set of prime factors with repetition of an integer n. These functions are first defined i n [20]. In this thesis, we refine some of the definitions presented there, and revisit some of the key results regarding such functions. The prime symmetric functions are polynomials over Q in the elementary prime symmetric functions, with values in Z. We look at basic properties of prime symmetric functions. We study the effect of iteration of these functions, and look at the question: when does iterating produce cycles? We consider the inverse question of when and in how many ways a number n can be expressed as f(m) for certain predetermined prime symmetric functions. As well, we look at asymptotic approximations for certain classes of prime symmetric functions.

description: We have developed the Hamiltonian theory for collective longitudinally polarized colorless excitations (plasmons) in a high-temperature gluon plasma using the general formalism for constructing the wave theory in nonlinear media with dispersion, which was developed by V.E. Zakharov. In this approach, we have explicitly obtained a special canonical transformation that makes it possible to simplify the Hamiltonian of interaction of soft gluon excitations and, hence, to derive a new effective Hamiltonian. The approach developed here is used for constructing a Boltzmann-type kinetic equation describing elastic scattering of collective longitudinally polarized excitations in a gluon plasma as well as the effect of the so-called nonlinear Landau damping. We have performed detailed comparison of the effective amplitude of the plasmon-plasmon interaction, which is determined using the classical Hamilton theory, with the corresponding matrix element calculated in the framework of high-temperature quantum chromodynamics; this has enabled us to determine applicability limits for the purely classical approach described in this study.

description: PTFO 8-8695 (CVSO 30) is a star in the 7-10 million year old Orion-OB1a cluster that shows brightness dips that resemble planetary transits. Although strong evidence against the planet hypothesis has been presented, the possibility remains debated in the literature. To obtain further clues, we inspected data from the NASA Transiting Exoplanet Survey Satellite (TESS) and the ESA Gaia mission. The Gaia data suggest that PTFO 8-8695 is a binary: the photometric data show it to be overluminous with respect to members of its kinematic group, and the astrometric data are inconsistent with a single star. The TESS light curve shows two different photometric periods. The variability is dominated by a sinusoidal signal with a period of 11.98 hr, presumably caused by stellar rotation. Also present is a 10.76 hr signal consisting of a not-quite sinusoid interrupted by hour-long dips, the type of signal previously interpreted as planetary transits. The phase of the dips is nearly 180$^\circ$ away from the phase of the originally reported dips. As noted previously, this makes them difficult to explain as planetary transits. Instead, we believe that PTFO 8-8695 is a pair of young and rapidly rotating M dwarfs, one of which shows the same "transient-dipper" behavior that has been seen in at least 5 other cases. The origin of these transient dips is still unknown but likely involves circumstellar material.

description: We conducted a systematic comparison of statistical methods used for the analysis of time-to-event outcomes under various proportional and nonproportional hazard (NPH) scenarios. Our study used data from recently published oncology trials to compare the Log-rank test, still by far the most widely used option, against some available alternatives, including the MaxCombo test, the Restricted Mean Survival Time Difference (dRMST) test, the Generalized Gamma Model (GGM) and the Generalized F Model (GFM). Power, type I error rate, and time-dependent bias with respect to the RMST difference, survival probability difference, and median survival time were used to evaluate and compare the performance of these methods. In addition to the real data, we simulated three hypothetical scenarios with crossing hazards chosen so that the early and late effects 'cancel out' and used them to evaluate the ability of the aforementioned methods to detect time-specific and overall treatment effects. We implemented novel metrics for assessing the time-dependent bias in treatment effect estimates to provide a more comprehensive evaluation in NPH scenarios. Recommendations under each NPH scenario are provided by examining the type I error rate, power, and time-dependent bias associated with each statistical approach.

description: The dark energy model with the equation of state p_d=-rho_d - A rho_d^alpha is studied. The model comprises and provides realization of several types of singularities in different parameter regimes: the divergence of the dark energy density and pressure at finite time and finite value of the scale factor, the singularity of the "big rip" type and the sudden future singularity recently introduced by Barrow. For parameter choices which lead to a nonsingular expansion of the universe, various types of the asymptotic evolution are found. The entire time evolution of the universe is described both analytically and numerically. The advantages of this dark energy EOS as a parametrization of dark energy are discussed.

Toda systems in closed string tachyon condensation

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

description: We consider $tt^*$ equations appearing in the study of localized tachyon condensations. They are described by various Toda system when we consider the condensation by the lowest tachyon corresponding to the monomial $xy$. The tachyon potential is calculated as a solution to these equations. The Toda system appearing in the deformation of $\C^2/\Z_n$ by $xy$ is identical to that of $D_n$ singularity deformed by $x$. For $\C^3/\Z_n$ with $xyz$ deformation, we find only generic non-simple form, similar to the case appearing in $\C/\Z_5\to \C/\Z_3$ and we discuss the difficulties in these cases.

description: Despite the nutritional guidelines promoting consumption of fruits and vegetables, the level of fruits and vegetable consumption is drastically below the recommended levels nationally, as well as at the state levels. Among factors that may influence consumption of fruits and vegetables, it is held that factors within the food environment such as the availability of retail types that are conducive for easy access to fruits and vegetables within communities may be presenting barriers to purchase. We employ multilevel modeling approaches to investigate the determinants of fruit and vegetable intake in North Carolina, accounting for food environment factors. Results of the study indicate that availability of supermarkets and full service restaurants is associated positively with fruits and vegetable consumption while fast food outlets are associated negatively. Other smaller store types were not statistically significant. Individual factors including age, being female, employed, income and education all were positively associated with fruits and vegetable consumption. The significant positive association of area level food environmental factors with the consumption of fruits and vegetables indicates a complementary role for intervention directed at improving the availability of supermarket type stores so as to impact healthy food purchases and consumption.

description: We present AsterX, a novel open-source, modular, GPU-accelerated, fully general relativistic magnetohydrodynamic (GRMHD) code designed for dynamic spacetimes in 3D Cartesian coordinates, and tailored for exascale computing. We utilize block-structured adaptive mesh refinement (AMR) through CarpetX, the new driver for the Einstein Toolkit, which is built on AMReX, a software framework for massively parallel applications. AsterX employs the Valencia formulation for GRMHD, coupled with the Z4c formalism for spacetime evolution, while incorporating high resolution shock capturing schemes to accurately handle the hydrodynamics. AsterX has undergone rigorous testing in both static and dynamic spacetime, demonstrating remarkable accuracy and agreement with other codes in literature. Using subcycling in time, we find an overall performance gain of factor 2.5 to 4.5. Benchmarking the code through scaling tests on OLCF's Frontier supercomputer, we demonstrate a weak scaling efficiency of about 67%-77% on 4096 nodes compared to an 8-node performance.

Non-local growth of Penrose tilings
Creators: name: Ross, Elissa Joanne
Publisher: name: University of British Columbia
Year: 2009

description: The problem of mistakes in Penrose tilings will be investigated. Specifically, we will consider the non-locality of any growth process that attempts to avoid errors in the construction of a tiling of the plane by Penrose rhombs. This discussion will be framed by considering the one dimensional version of this problem for Fibonacci Tilings, the aperiodic tilings of the line. These considerations lead to the conclusion that local growth algorithms for correct Penrose tilings of the plane do not exist.
Inhomogeneous models of interacting dark matter and dark energy

description: We derive and analyze a class of spherically symmetric cosmological models whose source is an interactive mixture of inhomogeneous cold dark matter (DM) and a generic homogeneous dark energy (DE) fluid. If the DE fluid corresponds to a quintessense scalar field, the interaction term can be associated with a well motivated non--minimal coupling to the DM component. By constructing a suitable volume average of the DM component we obtain a Friedman evolution equation relating this average density with an average Hubble scalar, with the DE component playing the role of a repulsive and time-dependent $Λ$ term. Once we select an ``equation of state'' linking the energy density ($μ$) and pressure ($p$) of the DE fluid, as well as a free function governing the radial dependence, the models become fully determinate and can be applied to known specific DE sources, such as quintessense scalar fields or tachyonic fluids. Considering the simple equation of state $p= (γ-1) μ$ with $0\leqγ<2/3$, we show that the free parameters and boundary conditions can be selected for an adequate description of a local DM overdensity evolving in a suitable cosmic background that accurately fits current observational data. While a DE dominated scenario emerges in the asymptotic future, with total $Ω$ and $q$ tending respectively to 1 and -1/2 for all cosmic observers, the effects of inhomogeneity and anisotropy yield different local behavior and evolution rates for these parameters in the local overdense region. We suggest that the models presented can be directly applied to explore the effects of various DE formalisms on local DM cosmological inhomogeneities.
