description: It is known that the Kimura 3ST model of sequence evolution on phylogenetic trees can be extended quite naturally to arbitrary split systems. However, this extension relies heavily on mathematical peculiarities of the K3ST model, and providing an analogous augmentation of the general Markov model has thus far been elusive. In this paper we rectify this shortcoming by showing how to extend the general Markov model on trees to to include arbitrary splits; and even further to more general network models. This is achieved by exploring the algebra of the generators of the continuous-time Markov chain together with the "splitting" operator that generates the branching process on phylogenetic trees. For simplicity we proceed by discussing the two state case and note that our results are easily extended to more states with little complication. Intriguingly, upon restriction of the two state general Markov model to the parameter space of the binary symmetric model, our extension is indistinguishable from the previous approach only on trees; as soon as any incompatible splits are introduced the two approaches give rise to differing probability distributions with disparate structure. Through exploration of a simple example, we give a tentative argument that our approach to extending to more general networks has desirable properties that the previous approaches do not share. In particular, our construction allows for the possibility of convergent evolution of previously divergent lineages; a property that is of significant interest for biological applications.

title: Deep Learning Data and Indexes in a Database
Creators: name: Sharma, Vishal
Publisher: name: Utah State University

description: A database is used to store and retrieve data, which is a critical component for any software application. Databases requires configuration for efficiency, however, there are tens of configuration parameters. It is a challenging task to manually configure a database. Furthermore, a database must be reconfigured on a regular basis to keep up with newer data and workload. The goal of this thesis is to use the query workload history to autonomously configure the database and improve its performance. We achieve proposed work in four stages: (i) we develop an index recommender using deep reinforcement learning for a standalone database. We evaluated the effectiveness of our algorithm by comparing with several state-of-the-art approaches, (ii) we build a real-time index recommender that can, in real-time, dynamically create and remove indexes for better performance in response to sudden changes in the query workload, (iii) we develop a database advisor. Our advisor framework will be able to learn latent patterns from a workload. It is able to enhance a query, recommend interesting queries, and summarize a workload, (iv) we developed LinkSocial, a fast, scalable, and accurate framework to gain deeper insights from heterogeneous data.
title: Assessing the Relationship Between Geophytes and the Archaeological Presence of Maize in North America
Creators: name: Dorsey, Paige
Publisher: name: Utah State University
Year: 2021

description: This thesis investigates the possible relationship between the archaeological presence of maize, in the United States, and historical environmental variables, rainfall and temperature, in addition to the number of underground plants that store energy and nutrients, in a given area. The thought behind this is that where the abundance of these underground plant species is highest, the lower the number of archaeological sites containing maize because such resources were a more attractive alternative food than maize. Conversely, where geophytes are less abundant, archaeological instances of maize should be more abundant because maize is a better option in such environments for individuals who need to produce more food. My results indicate that the presence of archaeological maize is potentially impacted by the productivity of geophytes in the area along with climate variables that impact the productivity of maize. The concentration of precipitation during the growing season, in particular, has a consistently significant effect on the number of archaeological sites with maize. By better understanding the environmental conditions that make maize productivity more favorable, we can better understand the transition to agriculture.
title: Investigating Recommended Language Instruction of Complex Literary Texts: A Content Analysis of Close Reading Lesson Plans for Elementary Grades
Creators: name: Flory, Michelle
Publisher: name: Utah State University
Year: 2021

description: Expectations have been placed upon elementary teachers from the Common Core State Standards in English Language Arts to guide students through close readings of informational and literary texts. This content analysis examined online close reading lesson plans to determine common objectives in elementary close reading lessons using literary text and to delineate which aspects of language are recommended for close reading instruction. Lessons for primary and intermediate grade levels were stratified and highlighted which instructional moves and student tasks are recommended for making complex language in texts more comprehensible. Key findings indicate a lack of alignment in lesson planning between objectives, lesson content, recommended vocabulary, student tasks, and assessment of multiple aspects of language creating a possible challenge for teachers to use close reading lesson plans as clear resources of close reading instruction. The most common objectives centered on the processes and routines of close reading through discussions of elements of fiction. There is scarce representation of instruction or modeling of language structure grammar and syntax, figurative language, language use and conventions used in literary text language. Intentional and incidental vocabulary instruction and use of context clues is the predominant language focus.
title: Substance Use Initiation among Mexican Children: An Examination of Individual and Ecological Factors
Creators: name: Vázquez, Alejandro L.
Publisher: name: Utah State University
Year: 2021

description: Mexico is experiencing increased rates of substance use among children and adolescents. This is concerning as early substance use is associated with an increased risk for developing mental and physical health problems during adulthood. These outcomes may be prevented through early identification and intervention before individuals encounter the negative consequences of substance use/abuse. The current dissertation sought to improve our knowledge regarding factors associated with substance use and intention for first time use among Mexican children. Three manuscripts examined child individual characteristics and aspects of their environment. The first manuscript examined demographic characteristics to determine whether particular groups of children were at increased risk for substance use and intensions for first time use. We found that being a boy, of indigenous background, non-religious, and over developmental age for grade were all associated with risk. The second manuscript focuses on examining parent characteristics and practices on substance use and intention for first time use. We found that parental illicit substance use was associated with the largest increases in risk and positive parenting was a protective factor. The third manuscript utilized machine learning, an algorithmic approach that predicts membership in one of two groups, to assist in the identification of high value factors that distinguish between substance users and non-users. Findings from this research identified factors associated with childhood substance use at individual and environmental levels. Being a boy and having a best friend or father that used illicit substances were the key indicators that could provide valuable information as screening questions. These findings provide valuable information needed to inform the development of early substance use prevention programs in Mexico. Results also suggest that machine learning may be an important tool in uncovering information that could bolster prevention efforts by improving our ability to identify children at risk for substance use. This research was supported by the Utah State University Psychology Department and School of Graduate Studies.

title: Computer-Based Training for MSWO Preference Assessment with Paraprofessionals in a Self-Contained Special Education Classroom
Creators: name: Robertson, Megan
Publisher: name: Utah State University
Year: 2021

description: Special educators are required to train the staff who work in their rooms to be competent in working with students with severe disabilities. Oftentimes these special educators do not have enough time to adequately train the staff and this often results in a high turnover rate and frustrated staff. This study looked at the effects of using a video model to train staff to complete a multiple stimulus without replacement assessment which identifies a student’s preferences. These preferences can then be used for a student to earn throughout their school day. The participants were paraprofessionals who work in a self-contained special education classroom. Data were collected on how well the participants were able to conduct the assessment before the video training as well as after. The results of this study demonstrated the participants were able to increase their accuracy and acquire the skills necessary to conduct an MSWO preference assessment using a video model. These results show that video modeling can be effective when training staff to in special education classrooms.

description: We report the discovery that R139 in 30 Doradus is a massive spectroscopic binary system. Multi-epoch optical spectroscopy of R139 was obtained as part of the VLT-FLAMES Tarantula Survey, revealing a double-lined system. The two components are of similar spectral types; the primary exhibits strong C III 4650 emission and is classified as an O6.5 Iafc supergiant, while the secondary is an O6 Iaf supergiant. The radial-velocity variations indicate a highly eccentric orbit with a period of 153.9 days. Photometry obtained with the Faulkes Telescope South shows no evidence for significant variability within an 18 month period. The orbital solution yields lower mass limits for the components of M1sin^3 i = 78 \pm 8 Msun and M2sin^3 i = 66 \pm 7 Msun. As R139 appears to be the most massive binary system known to contain two evolved Of supergiants, it will provide an excellent test for atmospheric and evolutionary models.

title: The Roles and Responsibilities of the COVID-19 Elementary Principal in Relation to Job Descriptions and Utah School Leadership Evaluation Metrics: A Case Study
Creators: name: Nielsen, Sarah R.
Publisher: name: Utah State University
Year: 2021

description: The purpose of this study was to examine the roles and responsibilities of elementary school principals in relation to how they are evaluated and what is included in their job descriptions during the COVID-19 pandemic. Because of the numerous policies that surround education and the COVID-19 pandemic, this study examined elementary school principals from a single school district in Utah. Seven principals agreed to participate in an interview that asked principals about their day-to-day responsibilities as a principal and how COVID-19 affected those responsibilities. Six principals agreed to participate in a daily reflection on how much time they spent participating in a variety of principal responsibilities. These principals reported feeling a great responsibility towards student learning and safety. However, they spent most of their time working on responsibilities either relating to the whole school (such as in formal meetings or watching out for students during recess, drop-off, etc.) or participating in responsibilities that do not directly affect the classroom or school such as their own professional learning or filling out reports. When compared to the district’s job description and the state’s evaluation template, there was evidence that principals were participating in nearly every job description item and evaluation strand. However, the job description and evaluation do not cover the same items or responsibility topics and principals reported participating in several responsibilities, particularly related to COVID-19, that were not included in either document. Suggestions are made for future research to examine these documents to ensure they are aligned and that the documents are dynamic enough to adjust to unusual circumstances, such as COVID-19, to ensure that principals do not feel conflicted in their responsibilities due to misalignment and the needs of the unforeseen moment.

This phenomenon appears to be triggered by the ambient electromagnetic background of very low frequency. We discuss this phenomenon in the framework of quantum field theory. A scheme able to account for the observations is proposed. The reported phenomenon could allow to develop highly sensitive detection systems for chronic bacterial and viral infections.

Assessing and analyzing urban tree condition using airborne remote sensing
Creators: name: Plowright, Andrew Alexander
Publisher: name: University of British Columbia
Year: 2016

description: Though urban forests play a key role in the sustainable development of cities, the environmental stressors faced by urban trees are numerous. City managers rarely have access to information on the condition of urban trees, which impedes both their management and the study of environmental factors that affect their vitality, such as landscape imperviousness. The research presented in this thesis aims to bridge this gap in information. The capacity of airborne light detection and ranging (LiDAR) and hyperspectral imagery to evaluate tree condition in the city of Surrey, British Columbia, Canada, is explored, and its relationship with impervious land cover is investigated. LiDAR was used to estimate two indicators of tree condition: crown density and tree height. Tree heights estimated by LiDAR were well correlated with field measurements (Pearson’s r = 0.927, p < 0.001), while the coefficient of variation of return height was able to predict crown density with an r2 = 0.617 for trees over 8 m. The heights of 1,914 trees across the city were then estimated using LiDAR. To account for the effects of age, species-specific height models were fitted using planting dates recorded by city authorities. The residuals from these models were then used as indicators of tree condition. A 1.0 m resolution classified land cover map (accuracy of 88.6%) was produced for the city, from which landscape imperviousness was then derived. When aggregated to broad-scale 0.5 km2 spatial units, negative relationships (r2 between 0.292 and 0.753) were found between height model residuals and land cover imperviousness. However, this relationship was found to be non-significant when examined at the individual tree level. We conclude that imperviousness does not appear to be a significant driver of tree height variation, with negative broad-scale relationships likely due to correlations with other unmeasured environmental variables associated with the urban-rural gradient. Hyperspectral and LiDAR data proved to be a powerful tool for mapping land cover and imperviousness. The results of this research show that airborne remote sensing is a promising tool for assessing the condition of urban trees and studying the environmental factors that impact their development.
title: Absolute Neutral Densities and Temperatures and Their Climatologies in the Middle Atmosphere Using an Optimal Estimation Method with Rayleigh-Scatter Lidar Observations Obtained at Utah State University
Creators: name: Price, Jonathan L.
Publisher: name: Utah State University
Year: 2021

description: The Earth’s atmosphere is comprised of layers which can be defined by their temperature characteristics. These layers are the troposphere, stratosphere, mesosphere and thermosphere. The region where life exists is in the troposphere, however the study of the layers above is important as changes in these regions can directly impact, or indicate significant changes in, weather in the troposphere. The mesosphere is the least well-known region because it is the most difficult to observe. One of the best tools for observing this region is the Rayleigh-scatter lidar. It is capable of remotely observing the entirety of the mesosphere with good time and altitude resolution. Until recently, this tool was used mainly to study temperatures in the middle atmosphere. In this work we introduce a new, reliable method for obtaining the absolute densities in this region. Long term trends were studied, and are presented, in the temperature and densities int the form of climatologies. Additionally, a case study of atmospheric tides is presented which utilizes the new densities and temperatures.

title: Valley Bottom Inundation Patterns in Beaver-Modified Streams: A Potential Proxy for Hydrologic Inefficiency
Creators: name: Bartelt, Karen
Publisher: name: Utah State University
Year: 2021

description: For centuries river management and land use actions in North America have caused widespread stream degradation where water now flows downstream with artificially high efficiency. When present, beaver dams slow the flow of water and decrease the efficiency of water conveyance through the landscape. These effects are often to the benefit of the function of natural physical processes and ecology of the stream. The benefits provided by beaver dams have been well studied at small scales, but the methods that these studies rely on are often expensive and time consuming and consequently not feasible to deploy at larger spatial scales or in diverse physical settings. We propose a tractable framework to monitor riverine systems that is based on mapping inundation, or flooding patterns. We mapped inundation area and type (types = free flowing, ponded, and overflow) in beaver dam complexes in diverse physical settings in which beavers tend to build different types of dams. Our mapping of over 75 snapshots of inundation at 37 sites suggest that beaver dams change inundation patterns by creating more diverse surface inundation patterns and slowing down water so that more inundation can occur, even at low flows. On average, at 37 sites, undammed conditions inundate 6.8% (range of 2.7% to 17.4%) of their valley bottoms at low flows. In contrast, sites with beaver dams present inundate 23.3% (range of 9.5% to 47.5%) of the valley bottom at low flows. Undammed sites predominately exhibited free flowing ( > 99%) inundation, whereas dammed sites had a mix of all three inundation types. This research also reveals that low slope and the small size of streams most typically reported in beaver dam studies are unnecessarily restrictive. We report notable changes to inundation patterns in both steeper gradient ( > 6%) streams and in the floodplains of larger rivers where beaver do not typically dam the main channel. This research also proposes the use of inundation mapping as a proxy for other important physical processes that are difficult to explicitly measure.

description: A generalized true anomaly-type parametrization, convenient to describe both bound and open orbits of a two-body system in general relativity is introduced. A complete description of the time evolution of both the radial and of the angular equations of a binary system taking into account the first order post-newtonian (1PN) is given. The gravitational radiation field emitted by the system is computed in the 1PN approximation including higher multipole moments beyond the standard quadrupole term. The gravitational waveforms in the time domain are explicitly given up to the 1PN order for unbound orbits, but the results are also illustrated on binaries on elliptic orbits with special attention given to the effects of eccentricity.

title: Achieving a Sequenced, Relational Query Language with Log-Segmented Timestamps
Creators: name: Ahsan, M. A. Manazir
Publisher: name: Utah State University
Year: 2021

description: In a relational temporal database, typically each row of each table has a period timestamp to indicate the lifetime of that row. In order to evaluate a query in a temporal database, sequenced semantics comes into play. The semantics stipulates that the query must be evaluated simultaneously in each time instant using the data rows available at that point of time. Existing researches have proposed changes in the query evaluation engine to achieve sequenced semantics. In this paper we show a way to support sequenced semantics without modifying the query engine. We propose a noble construction log-segmented label to represent the lifetime and replace the period timestamp from each row with a log-segmented label that signifies when the tuple is alive. Then we translate a sequenced query to a non-temporal query by utilizing the properties of log-segmented label. The translated query has only operations already available in a typical relational database making the query readily executable in an unaltered installation of the database. Thus the sequenced query inevitably runs and retrieve data without changing query evaluation engine. Finally our implementation using Java language, ANTLR parser generator and PostgreSQL database demonstrates the feasibility of the proposed mechanism, which, to the best of our knowledge, has not been previously shown.

title: GPS-Denied Navigation Using Synthetic Aperture Radar Images and Neural Networks
Creators: name: White, Teresa
Publisher: name: Utah State University
Year: 2021

description: Unmanned aerial vehicles (UAV) often rely on GPS for navigation. GPS signals, however, are very low in power and easily jammed or otherwise disrupted. This paper presents a method for determining the navigation errors present at the beginning of a GPS-denied period utilizing data from a synthetic aperture radar (SAR) system. This is accomplished by comparing an online-generated SAR image with a reference image obtained a priori. The distortions relative to the reference image are learned and exploited with a convolutional neural network to recover the initial navigational errors, which can be used to recover the true flight trajectory throughout the synthetic aperture. The proposed neural network approach is able to learn to predict the initial errors on both simulated and real SAR image data.
Essays on game theory and stochastic evolution
Creators: name: McAvoy, Alexander Patrick
Publisher: name: University of British Columbia
Year: 2016

description: Evolutionary game theory is a popular framework for modeling the evolution of populations via natural selection. The fitness of a genetic or cultural trait often depends on the composition of the population as a whole and cannot be determined by looking at just the individual ("player") possessing the trait. This frequency-dependent fitness is quite naturally modeled using game theory since a player's trait can be encoded by a strategy and their fitness can be computed using the payoffs from a sequence of interactions with other players. However, there is often a distinct trade-off between the biological relevance of a game and the ease with which one can analyze an evolutionary process defined by a game. The goal of this thesis is to broaden the scope of some evolutionary games by removing restrictive assumptions in several cases. Specifically, we consider multiplayer games; asymmetric games; games with a continuous range of strategies (rather than just finitely many); and alternating games. Moreover, we study the symmetries of an evolutionary process and how they are influenced by the environment and individual-level interactions. Finally, we present a mathematical framework that encompasses many of the standard stochastic evolutionary processes and provides a setting in which to study further extensions of stochastic models based on natural selection.

The most important improvements concern the communication scheme, which now uses the mapping weights to define the intermediate mapping decomposition and the hybrid OpenMP/MPI parallelisation introduced in the SCRIP library for the mapping weight calculation. Efforts were also spent to improve the initialisation with the update of the MCT library from version 2.8 to 2.10.beta1 and to introduce new options introduced in the global CONSERV operation. Finally, additional results obtained with IS-ENES2 coupling technology benchmark, either testing new options or running on Marconi KNL, will be shown.

description: We present an implementation of the disconnected diagram contributions to quantities such as the flavor-singlet pseudoscalar meson mass which are accelerated by GPGPU technology utilizing the NVIDIA CUDA platform. To enable the exact evaluation of the disconnected loops we use a $16^3 \times 32$ lattice and $N_f=2$ Wilson fermions simulated by the SESAM Collaboration. The disconnected loops are also computed using stochastic methods with several noise reduction techniques. In particular, we analyze various dilution schemes as well as the recently proposed truncated s olver method. We find consistency among the different methods used for the determination of the $η^\prime$ mass, albeit that the gauge noise for the ensemble studied is large. We also find that the effect of 'dilution' d oes not go beyond that of optimal statistical noise in many cases. It has been observed, however, that spin dilution does have a significant effect for some quantities studied.

title: Aspects of the Life History of Three Catostomids Native to the Upper Colorado River Basin
Creators: name: McAda, Charles W.
Publisher: name: Utah State University
Year: 1977

description: The distribution, abundance and life history were studied for three catostomids -- the razorback sucker (Xyrauchen texanus), the flannel-mouth sucker (Catostomus latipinnis), and the bluehead sucker (Catostomus discobolus) -- all native to the upper Colorado River basin. The razorback sucker has declined in abundance due to man's impact upon the system and it has been recommended that this species be listed as ''threatened" on the U. S. Department of the Interior's list of Threatened or Endangered species [Personal corrmunication, G. C. Kobetich, U. S. Fish and Wildlife Service, Las Vegas, Nevada]. During this investigation, razorback suckers were found in relatively large concentrations at the mouth of the Yampa River and in a flooded gravel pit connected to the Colorado River near Grand Junction, Colorado. Flannelmouth and bluehead suckers were collected in large numbers throughout the study area.
Razorback and flannelmouth suckers spawned in April and May, when water temperatures were between 6 and 15 C. Bluehead suckers spawned later (June and early July) when water temperatures exceeded 15 C. It can be inferred from this study that razorback suckers made a spawning migration, but the data are insufficient to draw any conclusions about the pervasiveness of this phenomenon. There was no evidence that flannelmouth or bluehead suckers made a spawning migration.
Fecundity of razorback suckers was variable and ranged from 24,490 for a fish 529 mm in total length (TL) to 76,576 eggs for a fish 485 mm TL. The youngest razorback sucker that was collected during this study was age IV; all razorback suckers were mature. Flannelmouth suckers first matured at age IV and most fish were mature by age VII. Flannelmouth sucker fecundity ranged from 4,000 eggs (450 mm TL) to 40,000 eggs (500 mm TL). Bluehead suckers produced as few as 4,000 (340 mm TL) and as many as 20,000 eggs (430 mm TL). Bluehead and flannelmouth suckers from the Colorado River produced significantly greater numbers of eggs than fish of equivalent lengths from the Green and Yampa Rivers.
Razorback and flannelrnouth suckers collected in 1974-76 attained a maximum age of nine years. Razorback suckers from the Colorado River were significantly longer than fish of the same age from the Green and Yampa Rivers. Flannelmouth suckers from the Colorado River were significantly heavier than fish of equivalent lengths from the Green and Yampa Rivers. The differences in fecundity and growth rates for fish from the two locations can probably be attributed to differences in temperature between the rivers.

The BLRs in AGNs are believed to be associated with the outflows from the accretion disks. Most of the low-luminosity AGNs (LLAGNs) contain advection dominated accretion flows (ADAFs), which are very hot and have a positive Bernoulli parameter. ADAFs are therefore associated with strong outflows. We estimate the cooling of the outflows from the ADAFs, and find that the gases in such hot outflows always cannot be cooled efficiently by bremsstrahlung radiation. The ADAF may co-exist with the standard disk, i.e., the inner ADAF connects to the outer thin accretion disk at radius R_tr, in the sources accreting at slightly lower than the critical rate. For the ADAFs with >0.001 L_edd, a secondary small inner cold disk is suggested to co-exist with the ADAF due to the condensation process. We estimate the Compton cooling of the outflow, of which the soft seed photons either come from the outer cold disk or the secondary inner cold disk. It is found that the gas in the outflow far from the ADAF may be efficiently cooled to form BLR clouds due to the soft seed photons emitted from the cold disks, provided the transition radius of the ADAF to the outer cold disk is small or/and the secondary small cold disk has a luminosity >0.003L_edd. The BLR clouds can still be formed in the outflows from the outer cold thin disks, if the transition radius is not very large. For the sources with <0.001L_edd, the inner small cold disk is evaporated completely in the ADAF and outer thin accretion disk may be suppressed by the ADAF, which leads to the disappearance of the BLR. The physical implications of this scenario on the double-peaked broad-line emitters are also discussed.

description: We investigate thermal leptogenesis in a supersymmetric neutrinophilic Higgs model by taking phenomenological constraints into account, where, in addition to the minimal supersymmetric standard model, we introduce an extra Higgs field with a tiny vacuum expectation value (VEV) which generates neutrino masses. Thanks to this tiny VEV of the neutrinophilic Higgs, our model allows to reduce the mass of the lightest right-handed (s)neutrino to be ${\cal O}(10^5)$ GeV as keeping sufficiently large CP asymmetry in its decay. Therefore, the reheating temperature after inflation is not necessarily high, hence this scenario is free from gravitino problem.

title: Three Reports on Investigations into Mathematical Modeling Knowledge for Teaching
Creators: name: Tidwell, William Smith

description: A flurry of activity in mathematical modeling education was precipitated by the incorporation of standards for mathematical modeling into curricula worldwide. Mathematical modeling is a vital skill in STEM professions and mathematical modeling activities provide educators with ways to assess students’ capacity to creatively solve complex problems. Research suggests that mathematical modeling needs more emphasis in teacher education programs, and has placed focus on improving and understanding secondary preservice teachers’ conceptions of mathematical modeling. This dissertation addresses teachers’ content knowledge of mathematical modeling by reporting on three investigations: (1) an investigation of prospective elementary teachers’ conception of mathematical modeling, (2) an investigation with in-service teachers of the relevance of mathematical modeling curricular materials for their students, and (3) the development and preparation of a lesson in which preservice secondary teachers engage in modeling the memorization process. These reports investigate mathematical modeling in major areas of teacher education with prospective elementary, in-service, and preservice secondary teachers, respectively, and aim to elucidate the preparation of all teachers of mathematics to teach mathematical modeling.
Gravitational and electroweak unification by replacing diffeomorphisms with larger group

description: The covariance group for general relativity, the diffeomorphisms, is replaced by a group of coordinate transformations which contains the diffeomorphisms as a proper subgroup. The larger group is defined by the assumption that all observers will agree whether any given quantity is conserved. Alternatively, and equivalently, it is defined by the assumption that all observers will agree that the general relativistic wave equation describes the propagation of light. Thus, the group replacement is analogous to the replacement of the Lorentz group by the diffeomorphisms that led Einstein from special relativity to general relativity, and is also consistent with the assumption of constant light velocity that led him to special relativity. The enlarged covariance group leads to a non-commutative geometry based not on a manifold, but on a nonlocal space in which paths, rather than points, are the most primitive invariant entities. This yields a theory which unifies the gravitational and electroweak interactions. The theory contains no adjustable parameters, such as those that are chosen arbitrarily in the standard model.

Global neutrino data and recent reactor fluxes: status of three-flavour oscillation parameters

description: We present the results of a global neutrino oscillation data analysis within the three-flavour framework. We include latest results from the MINOS long-baseline experiment (including electron neutrino appearance as well as anti-neutrino data), updating all relevant solar (SK II+III), atmospheric (SK I+II+III) and reactor (KamLAND) data. Furthermore, we include a recent re-calculation of the anti-neutrino fluxes emitted from nuclear reactors. These results have important consequences for the analysis of reactor experiments and in particular for the status of the mixing angle $θ_{13}$. In our recommended default analysis we find from the global fit that the hint for non-zero $θ_{13}$ remains weak, at 1.8$σ$ for both neutrino mass hierarchy schemes. However, we discuss in detail the dependence of these results on assumptions concerning the reactor neutrino analysis.

title: Roadway-Embedded Transmitters and Multi-Pad Receivers for High Power Dynamic Wireless Power Transfer

description: Electric vehicles (EVs) offer considerable economic and environmental benefits to society. Despite the decreasing vehicle costs and increasing range of newer EVs, the problem of range anxiety still exists. Range anxiety, at its core, is an issue of charging speeds rather than a concern about the driving range. Dynamic wireless charging of EVs is seen as a potential solution to this issue of range anxiety. Further, wireless charging technology also helps the push towards level 5 autonomy and opens new opportunities for how an EV can be utilized.
Dynamic wireless power transfer (DWPT) systems typically require a high initial investment due to the scale of deployment needed and require a certain level of EV adoption before they become economically viable. The challenges facing DWPT technologies are broadly categorized into development, deployment and operation challenges. To address the deployment challenges, this dissertation presents the pavement integration of DWPT systems, and the design and validation of concrete-embedded wireless charging pads. To improve infrastructure utilization and address the operation challenge, different vehicle classes need to recharge from the same charging infrastructure. This is made possible by the use of multi-pad receivers, which allow different vehicle classes to receive different power levels using the same charging infrastructure. This work presents a scaled-down version of a multi-pad receiver system to demonstrate the operation and scalability of these modular receivers.
To help further reduce the cost of development and implementation of DWPT systems, finite element method (FEM) and circuit simulation models are presented. The time-domain simulations can be used to develop and validate various control and communication schemes without the need for expensive hardware implementation. Finally, leakage magnetic field reduction to ensure safety and compliance for DWPT systems is discussed, and an example system is analyzed using FEM simulations.

description: A controlled quantum system possesses a search landscape defined by the target physical objective as a function of the controls. This paper focuses on the landscape for the transition probability Pif between the states of a finite level quantum system. Traditionally, the controls are applied fields; here we extend the notion of control to also include the Hamiltonian structure, in the form of time independent matrix elements. Level sets of controls that produce the same transition probability value are shown to exist at the bottom Pif = 0.0 and top Pif = 1.0 of the landscape with the field and/or Hamiltonian structure as controls. We present an algorithm to continuously explore these level sets starting from an initial point residing at either extreme value of Pif . The technique can also identify control solutions that exhibit the desirable properties of (a) robustness at the top and (b) the ability to rapidly rise towards an optimal control from the bottom. Numerical simulations are presented to illustrate the varied control behavior at the top and bottom of the landscape for several simple model systems.
