description: Resolving faint galaxies in large volumes is critical for accurate cosmic reionisation simulations. While less demanding than hydrodynamical simulations, semi-analytic reionisation models still require very large N-body simulations in order to resolve the atomic cooling limit across the whole reionisation history within box sizes $\gtrsim 100 \, h^{-1} {\rm Mpc}$. To facilitate this, we extend the mass resolution of N-body simulations using a Monte Carlo algorithm. We also propose a method to evolve positions of Monte Carlo halos, which can be an input for semi-analytic reionisation models. To illustrate, we present an extended halo catalogue that reaches a mass resolution of $M_\text{halo} = 3.2 \times 10^7 \, h^{-1} \text{M}_\odot$ in a $105 \, h^{-1} {\rm Mpc}$ box, equivalent to an N-body simulation with $\sim 6800^3$ particles. The resulting halo mass function agrees with smaller volume N-body simulations with higher resolution. Our results also produce consistent two-point correlation functions with analytic halo bias predictions. The extended halo catalogues are applied to the \textsc{meraxes} semi-analytic reionisation model, which improves the predictions on stellar mass functions, star formation rate densities and volume-weighted neutral fractions. Comparison of high resolution large volume simulations with both small volume or low resolution simulations confirms that both low resolution and small volume simulations lead to reionisation ending too rapidly. Lingering discrepancies between the star formation rate functions predicted with and without our extensions can be traced to the uncertain contribution of satellite galaxies.

description: A vortex line, shaped by a zigzag of pinning centers, is described here through a three-dimensional unit cell containing two pinning centers positioned symmetrically with respect to its center. The unit cell is a cube of side $L=12ξ$, the pinning centers are insulating spheres of radius $R$, taken within the range $0.2ξ$ to $3.0ξ$, $ξ$ being the coherence length. We calculate the free energy density of these systems in the framework of the Ginzburg-Landau theory.

Observational and numerical study of daytime flows in an alpine valley
Creators: name: Rucker, Magdalena
Publisher: name: University of British Columbia
Year: 2009

description: Thermally-driven valley wind systems are an integral part of the meteorology in mountain valleys and hence play an important role in environmental issues of human habitation. While we have a basic understanding of the evolution and mechanisms of valley flows, very little is known about the spatial structures of these flows and how they relate to topography. This lack of understanding has been largely due to the lack of spatial resolution with conventional in-situ instrumentation. This study utilizes high spatially-resolved Doppler lidar measurements to examine the spatial structure of daytime thermally-driven valley flows in the Wipptal, Austria. Results are presented for a number of days which provides insight into which flow aspects are influenced externally and which ones are induced locally. Numerical simulations are conducted to elucidate the flow dynamics in the Wipptal and to explore the role of topography. Observations show that, regardless of external conditions, the wind speed increases with up-valley distance in the narrow section of the Wipptal. Analysis of the along-valley volume flux shows that the increase in wind speed cannot be explained as a Venturi effect due to the horizontal contraction of the valley sidewalls. Furthermore, significant subsidence must occurs in this part of the valley in order to balance the along-valley volume flux divergence. Numerical modeling of the flow in the Wipptal supports the notion that the observed flow structure is linked to the valley geometry. Advection processes, however, are also found to play a significant role. From these findings, it may be inferred that the along-valley kinematic structure is influenced by the geometry of the valley and that localized subsiding motion can occur over localized valley segments as a result of changes in the intra-valley pressure gradient. This calls into question the concept that heating in an entire catchment area is relayed back to the main valley through subsidence at the mouth of a tributary.

description: The inner region of circumstellar discs makes an extra near-infrared emission (NIR bump). Detecting and studying these NIR bumps from nearby stars have been done mostly through infrared interferometry. In this work, we study the feasibility of detecting NIR bumps for Galactic bulge stars through microlensing from observations by The Nancy Grace Roman Space Telescope (RST) survey. We first simulate microlensing light curves from source stars with discs in near-infrared. Four main conclusions can be extracted from the simulations. (i) If the lens is crossing the disc inner radius, two extra and wide peaks appear and the main peak of microlensing light curve is flattened. (ii) In microlensing events with the lens impact parameters larger than the disc inner radius, the disc can break the symmetry of light curves with respect to the time of closest approach. (iii) In caustic-crossing binary microlensing, the discs produce wide peaks right before entering and immediately after exiting from the caustic curves. (iv) The disc-induced perturbations are larger in the W149 filter than in the Z087 filter, unless the lens crosses the disc condensation radius. By performing a Monte Carlo simulation, the probabilities of detecting the disc perturbations by \wfirst~are estimated ~3 and 20 per cent in single and binary microlensing, respectively. We anticipate that RST detects around 109 disc-induced perturbations during its microlensing survey if 5 per cent of its source stars have discs.

description: Excerpts from the report: Institutions --penal, charitable, mental--comprise an outlet for food that has received little attention in market analysis. This may be attributed, in part, to the fact that the institutional outlet represents a relatively small part of the total market for agricultural products. Furthermore, information on this particular segment of the market has been costly and difficult to obtain. A pilot study designed to appraise institutions- -charitable, mental and penal--as a potential market for foods in large supply was made in 16 non-Federal institutions located in the northeastern and southeastern regions of the United States. Basic data obtained were the per capita quantities of food issued to institutional kitchens, the sources of supply, and the prices paid.

description: The influence of spatial confinement on the thermally excited stochastic cation dynamics of the room-temperature ionic liquid 1-N-butylpyridinium bis-((trifluoromethyl)sulfonyl)imide ([BuPy][Tf_2N]) inside porous carbide-derived carbons with various pore sizes in the sub- to a few nanometer range are investigated by quasi-elastic neutron spectroscopy. Using the potential of fixed window scans, i.e. scanning a sample parameter, while observing solely one specific energy transfer value, an overview of the dynamic landscape within a wide temperature range is obtained. It is shown that already these data provide a quite comprehensive understanding of the confinement-induced alteration of the molecular mobility in comparison to the bulk. A complementary, more detailed analysis of full energy transfer spectra at selected temperatures reveals two translational diffusive processes on different time scales. Both are considerably slower than in the bulk liquid and show a decrease of the respective self-diffusion coefficients with decreasing nanopore size. Different thermal activation energies for molecular self-diffusion in nanoporous carbons with similar pore size indicate the importance of pore morphology on the molecular mobility, beyond the pure degree of confinement. In spite of the dynamic slowing down we can show that the temperature range of the liquid state upon nanoconfinement is remarkably extended to much lower temperatures, which is beneficial for potential technical applications of such systems.

Nevertheless, already now our result is competitive to the standard extraction of V_us from K_e3 decays, and it is compatible with unitarity.

description: Gravitational physics is arguably better understood in the presence of a negative cosmological constant than a positive one, yet there exist strong technical similarities between the two settings. These similarities can be exploited to enhance our understanding of the more speculative realm of quantum cosmology, building on robust results regarding anti-de Sitter black holes describing the thermodynamics of holographic quantum field theories. To this end, we study 4-dimensional gravitational path integrals in the presence of a negative cosmological constant, and with minisuperspace metrics. We put a special emphasis on boundary conditions and integration contours. The Hawking-Page transition is recovered and we find that below the minimum temperature required for the existence of black holes the corresponding saddle points become complex. When the asymptotic anti-de Sitter space is cut off at a finite distance, additional saddle points contribute to the partition function, albeit in a very suppressed manner. These findings have direct consequences for the no-boundary proposal in cosmology, because the anti-de Sitter calculation can be brought into one-to-one correspondence with a path integral for de Sitter space with Neumann conditions imposed at the nucleation of the universe. Our results lend support to recent implementations of the no-boundary proposal focusing on momentum conditions at the "big bang".

description: We report an investigation of the self-energy screening effects for the $g$ factor of the ground state of Li-like ions. The leading screening contribution of the relative order $1/Z$ is calculated to all orders in the binding nuclear strength parameter $Zα$ (where $Z$ is the nuclear charge number and $α$ is the fine-structure constant). We also extend the known results for the $Zα$ expansion of the QED screening correction by deriving the leading logarithmic contribution of order $α^5\lnα$ and obtaining approximate results for the $α^5$ and $α^6$ contributions. The comparison of the two approaches yields a stringent check of consistency of the two calculations and allows us to obtain improved estimations of the higher-order screening effects.

title: Non-equilibrium processes and ergodicity-breaking in isolated quantum systems
Creators: name: Taylor, Scott Richard
Publisher: name: University of St Andrews
Year: 2019

description: In this thesis we consider isolated quantum systems influenced by disorder and external driving, and explore aspects of localisation and ergodicity-breaking in three different models. We first consider the XYZ spin chain in a disordered magnetic field; this system breaks the U(1) symmetry of the XXZ model and therefore violates the conservation of the z component of the total magnetisation. We identify a quantum phase transition between an ergodic phase and a many-body localised phase at a finite disorder strength that is strongly dependent on the size of the U(1) symmetry-breaking term. We also investigate the breakdown of thermalisation by studying the matrix elements of local operators in the basis of the system's eigenstates, and we find suggestive evidence of subdiffusive energy transport at disorder strengths preceding the localisation transition. We then consider a two-level time-dependent quantum system that is influenced by a fluctuating classical noise term. We show that the noise does not fully randomise the quantum state if the fluctuations of every noise parameter coupled to the system are perfectly correlated; the state of the system instead becomes distributed over a finite subset of the full state space. Lastly we consider a one-dimensional Anderson-localised system that is affected by randomly fluctuating onsite potentials. We explore how the spatiotemporal correlations between these onsite potentials affect the delocalisation of a particle initially localised on a single site.

description: We analyze stability of superfluid currents in a system of strongly interacting ultra-cold atoms in an optical lattice. We show that such a system undergoes a dynamic, irreversible phase transition at a critical phase gradient that depends on the interaction strength between atoms. At commensurate filling, the phase boundary continuously interpolates between the classical modulation instability of a weakly interacting condensate and the equilibrium quantum phase transition into a Mott insulator state at which the critical current vanishes. We argue that quantum fluctuations smear the transition boundary in low dimensional systems. Finally we discuss the implications to realistic experiments.

Grid-aware Distributed Model Predictive Control of Heterogeneous Resources in a Distribution Network: Theory and Experimental Validation

Publisher: name: arXiv

description: In this paper, we propose and experimentally validate a scheduling and control framework for distributed energy resources (DERs) that achieves to track a day-ahead dispatch plan of a distribution network hosting controllable and stochastic heterogeneous resources while respecting the local grid constraints on nodal voltages and lines ampacities. The framework consists of two algorithmic layers. In the first one (day-ahead scheduling), we determine an aggregated dispatch plan. In the second layer (real-time control), a distributed model predictive control (MPC) determines the active and reactive power set-points of the DERs so that their aggregated contribution tracks the dispatch plan while obeying to DERs operational constraints as well as the grids ones. The proposed framework is experimentally validated on a real-scale microgrid that reproduces the network specifications of the CIGRE microgrid benchmark system.

Episodic mixing and buoyancy-sorting representations of shallow cumulus convection
Creators: name: Zhao, Ming
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation combines a diagnostic study, a numerical simulation and a theory of cumulus mixing to investigate shallow cumulus convection and its representation in large-scale models. The objective is to facilitate the development of a cumulus parameterization scheme and also to improve our understanding of the mixing dynamics, transport and life-cycle of shallow cumulus clouds. Applying an episodic mixing and buoyancy sorting (EMBS) model to shallow clouds requires specification of the undilute eroding/mixing rate (UER), a cloud detrainment criterion and the cloud-environment mixing distribution. A diagnostic equation is formulated for the UER based on a convective equilibrium constraint. A particular UER profile is retrieved by applying the diagnostic equation to an observed trade cumulus boundary layer. Based on this framework, a study of the UER retrieval sensitivity to variations in the mixing distribution and the detrainment criterion is carried out. The retrieved UER decreases exponentially with height above cloud-base, suggesting a strong modulation by the cloud size distribution. The EMBS-diagnosed vertical mass flux is downward within the inversion layer and upward within the cloud layer, indicating the important role of cloud evaporation in cloud detrainment. A large eddy simulation (LES) is conducted to provide a further evaluation of the EMBS model and the diagnostic results. Numerical tracers are used to identify the cloudmixed region. Six clouds with a range of heights are isolated from the LES field. The results reveal that the lifetime-averaged vertical mass-flux profile decreases with height and becomes negative within the upper cloud layers. The simulated clouds produce cooling/ moistening in their upper portion of the penetration depth and warming/drying in the lower portion of their penetration depth. The success of the EMBS approach is found to be primarily due to its correct representation of the growing and dissipating phase of a cloud life-cycle. Unsaturated downdrafts are evaporatively driven and dominate the overall mass and buoyancy fluxes at upper cloud layers for all simulated clouds. The explicit simulation also strengthens a conclusion made in the diagnostic study that an equilibrium cloud size distribution can be seen as the product of the large scale forcing and dynamics of individual convective clouds.

description: X-ray diffraction experiments were performed on MnO confined in mesoporous silica SBA-15 and MCM-41 matrices with different channel diameters. The measured patterns were analyzed by profile analysis and compared to numerical simulations of the diffraction from confined nanoparticles. From the lineshape and the specific shift of the diffraction reflections it was shown that the embedded objects form ribbon-like structures in the SBA-15 matrices with channels diameters of 47-87 Å, and nanowire-like structures in the MCM-41 matrices with channels diameters of 24-35 Å. In the latter case the confined nanoparticles appear to be narrower than the channel diameters. The physical reasons for the two different shapes of the confined nanoparticles are discussed.

description: Ethanol mandates and high fuel prices have led to an increase in the number of ethanol plants in the U.S. in recent years. In turn, this has led to an increase in the production of distillers dried grains (DDGs) as a co-product of ethanol production. DDG production in 2006 is estimated to be near 11 million tons. A sharp increase in ethanol production and thus DDGs is expected in 2007 with an increase with the number of ethanol plants. As with most competitive industries, there is some level of price risk in handling DDGs and no futures contract available for this co-product. Ethanol plants, as well as users of DDGs, may find cross-hedging DDGs with corn or soybean meal (SBM) futures as an effective means of managing risk. Traditionally, DDGs are hedged using only corn futures.
Inferring the Age of the Universe with Globular Clusters

description: We present an estimate of the absolute age of 68 galactic globular clusters obtained by exploiting the distribution of stars in the full color-magnitude diagram. In particular, we jointly estimate the absolute age, distance, reddening, metallicity ([Fe/H]) and [$α$/Fe] of each cluster, imposing priors motivated by independent observations; we also estimate possible systematics from stellar modeling. Our derived distances for the globular cluster sample are in agreement with those obtained from GAIA using main-sequence dwarf stars (where available), and the inferred ages are in good agreement with those previously published. The novelty of our approach is that, with the adopted priors, we are able to estimate robustly these parameters from the globular cluster color-magnitude diagram. We find that the average age of the oldest globular clusters is $t_{\rm GC}=13.32 \pm 0.1 {\rm (stat.)} \pm 0.5 {\rm (sys.)}$, at 68\% confidence level, including systematic uncertainties from stellar modeling. These measurements can be used to infer the age of the Universe, largely independently of the cosmological parameters: we find an age of the Universe $t_{\rm U}=13.5^{+0.16}_{-0.14} {\rm (stat.)} \pm 0.5 ({\rm sys.})$ at 68\% confidence level, accounting for the formation time of globular clusters and its uncertainty. This value is compatible with $13.8 \pm 0.02$ Gyr, the cosmological model-dependent value inferred by the Planck mission assuming the $Λ$CDM model.

description: The increase in commodity fund trading in the agricultural commodity futures markets has raised concern that this trading is degrading the price discovery performance of these markets. We used the Beveridge-Nelson Decomposition procedure to estimate the price discovery performance of the soybean futures and spot markets. We found that the price discovery performance of the soybean futures market has improved along with the increased commodity fund trading. Our results indicated that a portion of the price discovered in the soybean futures market is passed to the spot market.

subject: probability weighting

description: The objective of this study is to investigate how professional traders in futures and options markets behave under risk and uncertainty. Our preliminary findings suggest that most traders exhibit concave utility functions for gains and convex utility functions for losses, while their weighting functions are inverse s-shaped. However, differences in magnitude of the risk aversion parameters and the degree of probability weighting can lead to distinct behavior even if the shapes of utility and weighting functions are the same. Further, the typical pattern of prospect theory is more prevalent under risk but not as much under uncertainty. More combinations of shapes for utility and weighting functions are found under uncertainty, suggesting that different types of behavior emerge when people need to make their own assessments about the likelihood of events. Finally, our results are consistent with evidence of loss aversion and disposition effect found in studies of trading behavior in futures markets.

description: Some extension economists and others often recommend profit margin hedging in choosing the timing of crop sales. This paper determines producer’s utility function and price processes where profit margin hedging is optimal. Profit margin hedging is shown to be an optimal strategy under a highly restricted target utility function even in an efficient market. Although profit margin hedging is not the optimal rule in the presence of mean reversion, it can still be profitable if prices are mean reverting. Simulations are also conducted to compare the expected utility of profit margin hedging strategy with the expected utility of other strategy such as always hedging and selling at harvest strategies. A variance ratio test is conducted to test for the existence of mean reversion in agricultural futures prices process. The simulation results show that the expected utility of profit margin hedging strategy is highest. The paired difference tests for the profit margin hedging and other two strategies shows that the expected utilities of profit margin hedging strategies are not significantly different from those of always hedging strategy, but are significantly different from those of selling at harvest strategy except when the transaction cost is considered. The results of variance ratio test indicate that there is little evidence that futures price of wheat follows mean reverting process.
Speeding up the Search for Axions with Quantum Squeezing
Creators: name: Backes, Kelly
Publisher: name: Zenodo
Year: 2021

description: The Haloscope at Yale Sensitive to Axion Cold dark matter (HAYSTAC) has now finished its first data collection run using quantum squeezed states to enhance the search for axions. The squeezed state receiver consists of two Josephson parametric amplifiers. The first squeezes vacuum noise, while the second amplifies a hypothetical axion signal against a background of squeezed noise. This protocol allows HAYSTAC to acquire data with noise levels below the standard quantum limit, increasing the rate at which we can scan axion parameter space by a factor of 2. In this talk, I will give an overview of the operations of the HAYSTAC experiment, and discuss our recent exclusion of axions in the 4.11 - 4.18 GHz range.
