description: Let $M$ be a compact manifold and $f:\,M\to M$ be a $C^1$ diffeomorphism on $M$. If $μ$ is an $f$-invariant probability measure which is absolutely continuous relative to Lebesgue measure and for $μ$ $a.\,\,e.\,\,x\in M,$ there is a dominated splitting $T_{orb(x)}M=E\oplus F$ on its orbit $orb(x)$, then we give an estimation through Lyapunov characteristic exponents from below in Pesin's entropy formula, i.e., the metric entropy $h_μ(f)$ satisfies $$h_μ(f)\geq\int χ(x)dμ,$$ where $χ(x)=\sum_{i=1}^{dim\,F(x)}λ_i(x)$ and $λ_1(x)\geqλ_2(x)\geq...\geqλ_{dim\,M}(x)$ are the Lyapunov exponents at $x$ with respect to $μ.$ Consequently, by using a dichotomy for generic volume-preserving diffeomorphism we show that Pesin's entropy formula holds for generic volume-preserving diffeomorphisms, which generalizes a result of Tahzibi in dimension 2.

description: We show that for a locally free action of a simply connected nilpotent Lie group on a compact manifold, if every real valued cocycle is cohomologous to a constant cocycle, then the action is parameter rigid. The converse is true if the action has a dense orbit. Using this, we construct parameter rigid actions of simply connected nilpotent Lie groups whose Lie algebras admit rational structures with graduations. This generalizes the results of dos Santos [Parameter rigid actions of the Heisenberg groups. Ergod. Th. & Dynam. Sys. 27 (2007), 1719-1735] concerning the Heisenberg groups.

description: In this paper we present a novel method to connect data on the visualization level. In general, visualizations are a dead end, when it comes to reusability. Yet, users prefer to work with visualizations as evidenced by WYSIWYG editors. To enable users to work with their data in a way that is intuitive to them, we have created Vizgr. Vizgr.com offers basic visualization methods, like graphs, tag clouds, maps and time lines. But unlike normal data visualizations, these can be re-used, connected to each other and to web sites. We offer a simple opportunity to combine diverse data structures, such as geo-locations and networks, with each other by a mouse click. In an evaluation, we found that over 85 % of the participants were able to use and understand this technology without any training or explicit instructions.

description: Based on a specific model with U(3) family gauge symmetry at $10^3$ TeV scale, we show its experimental signatures to search for. Since the gauge symmetry is introduced with a special purpose, its gauge coupling constant and gauge boson mass spectrum are not free. The current structure in this model leads to family number violations via exchange of extra gauge bosons. We investigate present constraints from flavor changing processes and discuss visible signatures at LHC and lepton colliders.

description: Flood risk is impacted by a range of physical and socio-economic processes. Hence, the quantification of flood risk ideally considers the complete flood risk chain, from atmospheric processes through catchment and river system processes to damage mechanisms in the affected areas. Although it is generally accepted that a multitude of changes along the risk chain can occur and impact flood risk, there is a lack of knowledge of how and to what extent changes in influencing factors propagate through the chain and finally affect flood risk. To fill this gap, we present a comprehensive sensitivity analysis which considers changes in all risk components, i.e. changes in climate, catchment, river system, land use, assets, and vulnerability. The application of this framework to the mesoscale Mulde catchment in Germany shows that flood risk can vary dramatically as a consequence of plausible change scenarios. It further reveals that components that have not received much attention, such as changes in dike systems or in vulnerability, may outweigh changes in often investigated components, such as climate. Although the specific results are conditional on the case study area and the selected assumptions, they emphasize the need for a broader consideration of potential drivers of change in a comprehensive way. Hence, our approach contributes to a better understanding of how the different risk components influence the overall flood risk.

description: The surge in the consumers’ use of smartphone for shopping drives the attention of retailers to upgrade their mobile commerce channel to offer their products and services. As mobile commerce becomes one of the most used channels for shopping globally, the apparel and fashion industry stands a huge opportunity to increase their sales revenue considering its position as one of the most shopped product categories online. In this study, the consumer culture theory and the perceived risk theory were adopted to investigate the influence of the perceived risks and the risk relief factors towards the purchase intentions of apparel, accessory and /or shoe products via a smartphone. Two studies were conducted with two consumer panels from countries that showed significant differences in technology utilization as presented by the Computer-Based Media Support Index (CMSI), (USA and Nigeria), to examine the discrepancies in consumers’ behavior.A total of 695 participants were recruited through the MTurk and Datadiggers consumer panels and a self-administered online survey was used to collect the primary data. The results of the multiple regression analysis showed significant relationships between the perceived product risk and the perceived social risks towards the purchase intentions of apparel, accessory, and/or shoe products via a smartphone for both countries. However, the prior mobile shopping experience, product information search and perceived value moderate the effect of perceived product risk towards the purchase intention for the Nigerian consumers. This showed their critical roles in reducing the perceived product risk. In addition, the result showed a significant and positive influence of the prior mobile shopping experience towards the purchase intentions of apparel, accessory and/shoe products via a smartphone for both countries. This result suggests that consumers with shopping experience on a smartphone are more likely to purchase apparel, accessory, and/or shoe products via a smartphone.

On running a numerical weather prediction model from an ensemble mean initial and boundary condition
Creators: name: Steinhart, Rachel
Publisher: name: University of British Columbia
Year: 2022

description: The North American Ensemble Forecast System (NAEFS) is used as initial and boundary conditions (IBCs) for the Weather Research and Forecasting Model (WRF) to determine whether ensemble mean initial conditions can be used to successfully initialize a deterministic model, and to analyze how well they perform. Ensemble-average forecasts are usually more accurate than deterministic forecasts, even though the relationship between different forecast fields such as pressure, temperature, and winds can be unphysical. For this reason, it has been often assumed that ensemble average forecasts cannot be used as initial conditions for deterministic models. This research challenges that assumption. Two parallel WRF runs are tested: one with NAEFS ensemble mean IBCs, and the other with traditional deterministic IBCs from the Global Forecast System (GFS) to serve as a benchmark. The NAEFS initialized forecast (NAEFS-WRF) and the GFS initialized forecast (GFS-WRF) were run for a full year, September 2019 through August 2020. The model was set up to cover British Columbia, Canada and Alberta, Canada, with a 36 km horizontal grid scale. Two-meter hourly temperature, two-meter daily maximum and minimum temperatures, daily accumulated precipitation and 90th percentile daily accumulated precipitation events were verified against station observations to determine the accuracy of both NAEFS-WRF and GFS-WRF. The NAEFS-WRF forecast showed increasing skill compared to the GFS-WRF forecast at longer forecast horizons. The mean absolute error (MAE) spread and range was very similar for both forecasts, indicating that they performed similarly, and NAEFS-WRF developed no unreasonable trends in spite of the supposedly “unphysical” NAEFS fields. For rare/extreme (90th percentile) precipitation events, GFS-WRF was slightly more accurate at all forecast horizons. However, NAEFS-WRF was superior in high-precipitation subdomains, such as along the British Columbia coast and in Northern British Columbia at longer forecast horizons. The False Alarm Ratio and Probability of detection results showed that both forecasts could categorically predict whether precipitation would occur almost 90% of the time. This study finds that ensemble mean IBCs can be used to successfully drive a higher-resolution deterministic forecast model to create a reasonable forecast.

This allows us to derive lower bounds on the classical dimension necessary to reproduce given measurement data. Furthermore, we generalise the concept of quantum dimension witnesses to arbitrary quantum systems, allowing one to place a lower bound on the Hilbert space dimension necessary to reproduce certain data. Illustrating these ideas, we provide simple examples of classical and quantum dimension witnesses.

WHAT ARE THE RELATIONSHIPS BETWEEN CLIMATE CHANGE AND LAWN MANAGEMENT IN DRIVING FUTURE LAWN IRRIGATION RATES IN EASTERN WASHINGTON?
Creators: name: Deshar, Rojina
Publisher: name: Washington State University
Year: 2022

description: Climate change impacts in eastern Washington are expected to alter the timing and volume of precipitation received. These changes could have significant impacts on residential outdoor water use particularly if water supply systems are unable to meet the forecasted demand due to both declining water resources and rising climate-driven water use. Residential lawns often require relatively large volumes of water to maintain and demands have increased as green lawns have become more pervasive in residential areas as the population expands. Such increases in water demand can have severe consequences for water management in counties in eastern Washington which are relatively arid. Understanding the potential consequences of the relationship between climate change and lawn maintenance will be necessary for understanding how lawn irrigation can be more efficient in a drier future. As outdoor water use is more elastic than indoor use, residential lawn irrigation is also attractive for achieving water savings. Although lawns are widespread, the impact of climate change on consumptive use of municipal water is relatively understudied. To accomplish this, Chapter 2 details our use of VIC-CropSyst, a coupled framework consisting of a macroscale hydrologic model and agricultural model. The model output is used to explore gaps related to the potential impacts of climate change and atmospheric CO2 increases on irrigation demand on a regional scale in eastern Washington counties. In this study, we ran 17 General Circulation Models (GCMs) and future Representative Concentration Pathways (RCP) scenarios with different lawn management events to determine what likely future lawn irrigation rates will be in the face of climate change. The result shows that the need for lawn irrigation will increase and management guidance, like clipping events, and grass height maintenance could be the best practice for estimating the right amount of water with changing future climate.
description: Chapter 3 explored the impacts of precipitation variability and watering restrictions on lawn irrigation practices in the City of Moses Lake. Results showed that households were responsive to precipitation change using more water in dry years and less in wet years and the restrictions were an effective tool for reducing outdoor water use.

description: A class of exclusion processes in which particles perform history-dependent random walks is introduced, stimulated by dynamic phenomena in some biological and artificial systems. The particles locally interact with the underlying substrate by breaking and reforming lattice bonds. We determine the steady-state current on a ring, and find current-reversal as a function of particle density. This phenomenon is attributed to the non-local interaction between the walkers through their trails, which originates from strong correlations between the dynamics of the particles and the lattice. We rationalize our findings within an effective description in terms of quasi-particles which we call front barriers. Our analytical results are complemented by stochastic simulations.

description: We study time evolution of the $Q$ ball in thermal logarithmic potential using lattice simulations. As the temperature decreases due to the cosmic expansion, the thermal logarithmic term in the potential is eventually overcome by a mass term, and we confirm that the $Q$ ball transforms from the thick-wall type to the thin-wall type for a positive coefficient of radiative corrections to the mass term, as recently suggested. Moreover, we find that the $Q$ ball finally "melts down" when the $Q$-ball solution disappears. We also discuss the effects of this phenomenon on the detectability of gravitational waves from the $Q$-ball formation.

Moral hazard under discrete information disclosure: Evidence from food-safety inspections

description: This paper provides evidence on the responses of producers to mandatory disclosure of discrete quality ratings, a type of policy sometimes referred to as “naming and shaming”. The context is a series of four regulatory changes undertaken by the U.S. Department of Agriculture (USDA) over 2006–2015, regarding disclosure of information about the results of tests for Salmonella in chicken carcasses at slaughter establishments. If establishments exceed certain rates of positive samples, they are designated “Category 2” or “Category 3”. Under some policy regimes, Category 2 and 3 establishments have been listed on a public USDA website. I employ carcass-level data on Salmonella test results over 1999–2018 for all federally inspected establishments to explore the effects of public disclosure and other policy changes on Salmonella test outcomes. First, using a regression discontinuity approach, I demonstrate that: (1) When establishments fail to meet categorization thresholds but these failures do not subject them to public disclosure, Salmonella test performance worsens. (2) When establishments fail to meet thresholds and are therefore subjected to public disclosure, there is no statistically significant change in Salmonella test performance. (3) Under one policy regime, establishment operators relaxed efforts after sustained good Salmonella test performance ensured they would avoid public disclosure. Second, I document that when establishments have more leeway with respect to the thresholds, their performance on Salmonella tests worsens. Third, I use a regression discontinuity in time approach to demonstrate the effects of the series of policy changes on average Salmonella test results. I show that the introduction of public disclosure in 2008 reduced the average rate of positive Salmonella samples by about 55 percent. On the other hand, a tightening of standards in 2011 had a bifurcating effect wherein establishments that performed poorly (prior to the policy change) tended to perform even worse and middling establishments tended to improve. There was no statistically significant effect on the best-performing establishments. The net effect of the tightening of standards in 2011 was to more than double average Salmonella rates. My results provide evidence that the public disclosure of discrete information about Salmonella in chicken carcasses results in producers exerting extra effort to avoid disclosure, and less effort when disclosure status is already certain.
A HIGH-FIDELITY, CONTINUOUS ORTHO-PARAHYDROGEN MEASUREMENT AND CONVERSION SYSTEM
Creators: name: Bunge, Carl Dale
Publisher: name: Washington State University
Year: 2022

description: Production and consumption of liquid hydrogen is set to increase many orders of magnitude in the upcoming decades. Yet an entire liquid shipment can be boiled-off from the exothermic ortho-parahydrogen reaction if not performed during liquefaction. Measurements of ortho-parahydrogen composition have been historically challenging which hinders routine analysis. Included are experimental results of a continuous flow, in-situ Raman spectroscopy system for sampling ortho-parahydrogen composition. Correlation between Raman peak intensities and ortho-parahydrogen ratios demonstrates the actual number of molecules present in a given J mode is dependent on Boltzmann distribution, partition function, anisotropic polarizability, and scattering frequency. Consistent definitions of orthohydrogen percentage as related to Raman peak areas allow true orthohydrogen percentages to be obtained from sub 80K sample temperatures. The degeneracy of J mode populations as described by full statistical thermodynamics allows a correction to obtain true orthohydrogen percentages. This correction is completed with known experimental peak areas which correspond to confirmed equilibrium orthohydrogen percentage values. Simultaneous Raman measurement before and after catalytic packed bed and vortex tube ortho-parahydrogen conversion devices allow improved measurement to verify conversion performance. For example, a catalyzed dual outlet vortex tube produced a raw Raman measured para-orthohydrogen conversion of 6.3% from inlet to outlet. When calibrated to the true orthohydrogen percentage, it equates to 7.3% compared to the theoretical of 8.7% based off experimental temperature differentials. The results indicate application in optimizing liquefaction packed bed and reducing boil-off through vortex tube related heat exchangers applications. Together, these methods of orthohydrogen and parahydrogen conversion and measurement allow for increased liquid hydrogen storage optimization.

Inference under finite mixture models : distributed learning and approximate inference
Creators: name: Zhang, Qiong
Publisher: name: University of British Columbia
Year: 2022

description: Finite mixture models are widely used to model data that exhibit heterogeneity. In machine learning, they are often used as probabilistic models for clustering analysis. In the application of finite mixtures to real datasets, the most fundamental task is to learn model parameters. In modern applications, datasets are often too large to be stored in a single facility and are distributed across data centres. To learn models on these distributed datasets, split-and-conquer (SC) approaches are often used. SC approaches consist of two steps: they first locally learn one model per data centre and then send these local results to a central machine to be aggregated. Since the parameter spaces of mixtures are non-Euclidean, existing aggregation methods are not appropriate. We develop a novel computationally efficient aggregation approach for SC learning of finite mixtures. We show that the resulting estimator is root-n-consistent under some general conditions. Experiments show the proposed approach has comparable statistical performance with the global estimator based on the full dataset, if the latter is feasible. It also has better statistical and computational performance than some existing methods for learning mixtures on large datasets. Finite mixtures are also widely used to approximate density functions of various shapes. When mixtures are used in graphical models to approximate density functions, the order of the mixture increases exponentially due to recursive procedures and the inference becomes intractable. One way to make the inference tractable is to use mixture reduction, that is, to approximate the mixture by one with a lower order. We propose a novel reduction approach by minimizing the Composite Transportation Divergence (CTD) between two mixtures. The optimization problem can be solved by a majorization minimization algorithm. We show that many existing algorithms for reduction are special cases of our approach. This finding allows us to provide theoretical support for these existing algorithms. Our approach also allows flexible choices for cost functions in CTD. This flexibility allows our approach to have better performance than existing approaches. We also discuss other related learning issues under finite mixtures.

An update on single field models of inflation in light of WMAP7

description: In this paper we summarise the status of single field models of inflation in light of the WMAP 7 data release. We find little has changed since the 5 year release, and results are consistent with previous findings. The increase in the upper bound on the running of the spectral index impacts on the status of the production of Primordial Black Holes from single field models. The lower bound on the equilateral configuration of the non-gaussianity parameter is reduced and thus the bounds on the theoretical parameters of (UV) DBI single brane models are weakened. In the case of multiple coincident branes the bounds are also weakened and the two, three or four brane cases will produce a tensor-signal that could possibly be observed in the future.

description: Composite materials have been integrated into several industries, especially automotive, due to their ability to improve mechanical performance while decreasing weight. The automotive industry is mostly dominated by glass fiber (GF) reinforcements, which have proved to contain excellent strength, but lack in being environmentally friendly. There is a growing shift towards green materials as companies become more conscious about their environmental footprint. The incorporation of natural fibers is gaining attention since they significantly decrease the weight of composites and possess excellent strength-to-weight ratios while being an eco-friendly and renewable source. However, an old but not well-known substitution is basalt, another renewable resource with robust properties and the potential to surpass the performance of GF. The following research has observed how the mechanical, rheological, and environmental behaviors of basalt/hemp (BF/HF) hybrid reinforced polypropylene (PP) composites vary when manipulating the ratios of incorporated constituents. By understanding how the fibers interact with the polymer matrix, mixtures can be tailored to meet the property requirements of specific applications and can be easily integrated into manufacturing processes to successfully replace GF reinforcements. Results show that the incorporation of a coupling agent, MAPP, significantly improves the mechanical performance of BF/HF composites; however, more research needs to be done to match the strength of GF composites. On the contrary, preliminary data shows that BF composites have lower shear viscosity than GF and emits less harmful VOC emissions.

The airway epithelial response to human immunodeficiency virus : implications for HIV-associated chronic obstructive pulmonary disease
Creators: name: Hansi, Ravneet Kaur
Publisher: name: University of British Columbia
Year: 2022

description: RATIONALE: Despite the reduction in HIV-related mortality since the introduction of antiretroviral therapy, people living with HIV (PLWH) face a higher risk of developing age-associated comorbidities such as chronic obstructive pulmonary disease (COPD). Studies have found that HIV and COPD are independently associated with increased susceptibility and worse manifestations from respiratory viral infections. We hypothesize that COPD in PLWH is marked by increased inflammation in the airway epithelium which may potentiate injury during respiratory viral infections. METHODS: Primary human bronchial epithelial cells obtained from control, COPD, HIV, and HIV/COPD donors were cultured as monolayers and air-liquid interfaces (ALIs). RNA and protein lysates from these cultures were used to quantify HIV receptor mRNA and protein expression via qRT-PCR and western blot, respectively. ALI cultures were infected with respiratory syncytial virus (RSV) for 90 minutes and transepithelial electrical resistance (TEER) values were taken at time points: 0h, 24h, 48h and 72h. ALI cultures underwent immunohistochemistry staining for E-Cadherin quantification and mucus production quantification through Periodic Acid Schiff and MUC5AC staining. RESULTS: Western blot analysis of monolayer lysates demonstrated increased expression of CXCR4 in PLWH with and without COPD and increased expression of CCR5 in PLWH with COPD compared to control individuals. There was a trend towards higher CD4 expression in PLWH with and without COPD compared to control individuals. However, these differences were not found in either protein or mRNA HIV receptor expression in ALIs. TEER data demonstrated a decrease in epithelial resistance in RSV-infected ALIs derived from COPD and PLWH with COPD compared to PLWH without COPD and control individuals. There were no significant differences seen in E-cadherin expression and mucus production in RSV-infected ALIs. CONCLUSION: With an increased expression of HIV canonical receptors in the basal epithelial layer, particularly CCR5 and CXCR4, in PLWH with COPD, a greater interaction between virus and the airway epithelium may be possible, potentially causing damage to the airway epithelium. Furthermore, RSV infection induces greater epithelial permeability in patients with COPD regardless of HIV status. This could indicate that post-viral small airway injury may be driven more by COPD status rather than HIV infection alone.

description: This study examines the determinants of relational contractual performance using data from a series of laboratory experiments. There is currently limited empirical evidence on the determinants of contractual performance, which includes contractual acceptance, and the delivery of promised quantity/quality under the terms of the contract. While theory predicts that the primary drivers of contractual performance are high discount factors, and contract designs that obey individual rationality and self-enforcement constraints, the empirical analysis suggests that other determinants such as a history of prior cooperation can matter as much, if not more, than the theoretical constraint conditions.
title: Iceberg drift ensemble forecasting
Creators: name: Kielley, Evan
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: The goal of this thesis is to investigate whether ensemble modeling in iceberg drift
 forecasting improves predictions of an iceberg's trajectory. To do this, we have used
 a dynamic iceberg drift model and created an ensemble of realizations by applying
 stochastic perturbations to ocean current and wind reanalysis data, drawing from
 distributions of the ocean current and wind measured with ship-based instruments.
 In this study, we focus on simulating trajectories for two icebergs observed during
 the 2015 Statoil-ArcticNet research expedition. To conduct simulations, we initialized
 our model with observations of each iceberg at a particular time and location, then
 simulated a day of drift for each iceberg and compared the ensemble of simulation
 results to their actual known trajectories. In this comparison, we found inconsistent
 results. For one iceberg, the mean of the modelled trajectories was consistent with
 the observations but, for the other, none of the modelled trajectories were close.
 Overall, we conclude that ensemble modelling for iceberg drift forecasting is a useful
 technique only when the wind and current data driving the prediction is sufficiently
 accurate.
Long-lived Dark Higgs and Inelastic Dark Matter at Belle II

description: Inelastic dark matter is an interesting scenario for light thermal dark matter which is fully consistent with all cosmological probes as well as direct and indirect dark matter detection. The required mass splitting between dark matter $\chi_1$ and its heavier twin $\chi_2$ is naturally induced by a dark Higgs field which also provides a simple mechanism to give mass to the dark photon $A'$ present in the setup. The corresponding dark Higgs boson $h'$ is naturally the lightest dark sector state and therefore decays into Standard Model particles via Higgs mixing. In this work we study signatures with displaced vertices and missing momentum at Belle II, arising from dark Higgs particles produced in association with dark matter. We find that Belle II can be very sensitive to this scenario, in particular if a displaced vertex trigger is available in the near future.
Fluctuations, Saturation, and Diffractive Excitation in High Energy Collisions

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Diffractive excitation is usually described by the Good--Walker formalism for low masses, and by the triple-Regge formalism for high masses. In the Good--Walker formalism the cross section is determined by the fluctuations in the interaction. In this paper we show that by taking the fluctuations in the BFKL ladder into account, it is possible to describe both low and high mass excitation by the Good--Walker mechanism. In high energy $pp$ collisions the fluctuations are strongly suppressed by saturation, which implies that pomeron exchange does not factorise between DIS and $pp$ collisions. The Dipole Cascade Model reproduces the expected triple-Regge form for the bare pomeron, and the triple-pomeron coupling is estimated.

description: Distributed order fractional Langevin-like equations are introduced and applied to describe anomalous diffusion without unique diffusion or scaling exponent. It is shown that these fractional Langevin equations of distributed order can be used to model the kinetics of retarding subdiffusion whose scaling exponent decreases with time, and the strongly anomalous ultraslow diffusion with mean square displacement which varies asymptoically as a power of logarithm of time.
