title: Patterns of Microbial Diversity and Community Composition in Slot Canyons, Rock Pools, and Other Ephemeral and Perennial Aquatic Habitats
Creators: name: Madsen, Marley
Publisher: name: Utah State University
Year: 2020

description: Microbes are the most diverse life forms on the planet and perform many important ecological functions. However, despite the abundance, diversity, and ecological importance of microbes they are often overlooked and understudied in many natural systems, including freshwater habitats. This thesis details the first ever investigation of the microbial diversity and community composition within fresh water rock pools and slot canyons of the Colorado Plateau, Utah. The purpose of the study was to determine the relative importance of various microbial community assembly processes. This thesis also includes a meta-analysis of the microbial alpha diversity in other perennial and ephemeral aquatic systems around the globe. The purpose of the meta-analysis was to identify the relationship between microbial alpha diversity and disturbance from drying. Together, these studies complement one another by describing the microbial ecology of a very specific habitat type, rock pools, as well as a diverse group of globally distributed aquatic habitats.

title: 'LMshapemaker': Utilizing the 'Rmapshaper' R Package to Modify Shapefiles for Use in Linked Micromap Plots
Creators: name: Probst, Braden D.
Publisher: name: Utah State University
Year: 2020

description: In order to effectively create map-based visualizations, some map modifications need to be conducted to ensure the map is readable and interpretable. There are several issues that need to be addressed to achieve this. The boundaries of a country may be overly complex which is particularly true with coastal areas of countries. Regions may be small and not seen in the final plot, as is the case with many capital cities in the world’s countries such as Washington D.C. and the Federal District of Mexico City. In other countries, regions may geographically lie far away from the rest of the country as is the case with the Galàpagos Islands in Ecuador and the state of Hawaii in the United States. To best use maps with these issues in visualizations, users need to modify the boundaries and regions using software, such as arcGIS and R. Modifications have been done in the past for many countries, including the United States, France, Germany, Scotland, China, Korea, Argentina, Brazil, and others. Before the ‘LMshapemaker’ R software package, there was no single location containing usable maps. Access to the modified boundaries for the countries previously mentioned are spread out across different sources and R packages. ‘LMshapemaker’ is a new R package developed in this thesis that not only provides ready-to-use boundaries for a majority of the countries in the world, but also provides an accessible approach for users to modify boundaries to their preferences through a Shiny R app.

description: We examine spacetimes which generalize Lifshitz scaling to allow hyperscaling violation invariance (i.e. a constant conformal transformation) for the types of singularities frequently found in the Lifshitz case. We find that most of these spacetimes suffer either from a traditional naked curvature singularity or a null curvature singularity robust against stringy higher derivative corrections. We do find a one-parameter family that evades these issues but this family requires exotic matter, in particular involving a negative energy density that may not be interpreted as due to a cosmological constant.

description: Ceramic coatings were produced on AA7075-T6 alloy by micro-arc oxidation (MAO). The MAO treatment was performed at different duty cycles (8, 10, 15, and 20%). Effects of duty cycle on microstructure and fatigue behavior of the coated samples were investigated. Surface features and cross-section morphology, and fatigue fracture were observed by SEM and laser microscope. Phase structure and residual stress in the coatings were analyzed by X-ray diffraction. The nature and relaxation mechanism of the residual stress were revealed. Finally, the influence of the residual stress relaxation on the fatigue life at high and low cyclic stresses was explored.
Scheduling Two Machines with Dissimilar Costs
Creators: name: Moitra, Madhurupa
Publisher: name: University of Nevada, Las Vegas
Year: 2018

description: We consider two devices, which has states ON and OFF. In the ON state, the devices use their full power whereas in the OFF state the devices consume no energy but a constant cost is associated with switching back to ON. Such two devices are configured with different run and power-up costs on which a sequence of jobs must be processed. The object is to minimize the cost. Such systems are widely used to conserve energy, for example, to speed scale CPUs, to control data centers, or to manage renewable energy.
The problems are studied in the framework of online competitive analysis and we analyze a number of online algorithm and give lower bounds. The objective of the algorithm is to optimize the budget and analyzing how effectively it works.

description: Feedback control in quantum transport has been predicted to give rise to several interesting effects, amongst them quantum state stabilisation and the realisation of a mesoscopic Maxwell's daemon. These results were derived under the assumption that control operations on the system be affected instantaneously after the measurement of electronic jumps through it. In this contribution I describe how to include a delay between detection and control operation in the master equation theory of feedback-controlled quantum transport. I investigate the consequences of delay for the state-stabilisation and Maxwell's-daemon schemes. Furthermore, I describe how delay can be used as a tool to probe coherent oscillations of electrons within a transport system and how this formalism can be used to model finite detector bandwidth.

description: Molecular simulations as well as single molecule experiments have been widely analyzed in terms order parameters, the latter representing candidate probes for the relevant degrees of freedom. Notwithstanding this approach is very intuitive, mounting evidence showed that such description is not accurate, leading to ambiguous definitions of states and wrong kinetics. To overcome these limitations a framework making use of order parameter fluctuations in conjunction with complex network analysis is investigated. Derived from recent advances in the analysis of single molecule time traces, this approach takes into account of the fluctuations around each time point to distinguish between states that have similar values of the order parameter but different dynamics. Snapshots with similar fluctuations are used as nodes of a transition network, the clusterization of which into states provides accurate Markov-State-Models of the system under study. Application of the methodology to theoretical models with a noisy order parameter as well as the dynamics of a disordered peptide illustrates the possibility to build accurate descriptions of molecular processes on the sole basis of order parameter time series without using any supplementary information.

description: In the structure of therapeutic treatment, 35% are visits for pulpitis and periodontitis. The inflammatory process in periodontal disease is the main cause of tooth extraction. On an outpatient basis, 134 patients were examined with endodontic treatment with two of the most common types of pastes: resorcin-formalin and zinc oxide eugenol. According to the type of paste, all the examined patients were divided into two groups: 78 patients (51.5%) whose teeth were sealed with resorcin-formalin paste and 56 patients (48.5%) with zinc oxide eugenol paste. According to the study, in the group of teeth previously treated with resorcin-formalin paste, more than 2/3 were molars (77.0 + 2.2%), every fifth tooth was premolar (19.1 + 2.0% ) and the least were the front teeth (3.9 + 1.0%).

The Effects of Emotional Versus Rational Message Framing on Brand Attachment and Brand Loyalty
Creators: name: Woinowsky, Elisa
Publisher: name: University of Nevada, Las Vegas
Year: 2019

description: The purpose of this research is to investigate the relationship among message framing in social media, brand attachment, and brand loyalty for higher education institutions. In particular, this study compares the effectiveness of rational versus emotional message framing in different message contexts, such as sports or academic-related stories. Furthermore, this study examines the congruent effect between message framing and contents in higher education. Specifically, this study predicts that the more message framing and contents are congruent, the greater brand attachment and brand loyalty consumers will have. To analyze the effects of message framing and type of contents, this study adopts experimental design method. The findings of this research indicate that previous involvement with a brand predicts high brand attachment and brand loyalty and needs to be present prior to the strengthening process of brand attachment and brand loyalty. Therefore, previous brand involvement can be measured and related to the effectiveness of strengthening brand attachment and brand loyalty.

description: Transform coding is routinely used for lossy compression of discrete sources with memory. The input signal is divided into N-dimensional vectors, which are transformed by means of a linear mapping. Then, transform coefficients are quantized and entropy coded. In this paper we consider the problem of identifying the transform matrix as well as the quantization step sizes. We study the challenging case in which the only available information is a set of P transform decoded vectors. We formulate the problem in terms of finding the lattice with the largest determinant that contains all observed vectors. We propose an algorithm that is able to find the optimal solution and we formally study its convergence properties. Our analysis shows that it is possible to identify successfully both the transform and the quantization step sizes when P >= N + d where d is a small integer, and the probability of failure decreases exponentially to zero as P - N increases.

description: We report in detail our experiments on the conduction of $λ$ DNA molecules over a wide range of temperature deposited across slits in a few nanometers thick platinum film. These insulating slits were fabricated using focused ion beam etching and characterized extensively using near field and electron microscopy. This characterization revealed the presence of metallic Ga nanoparticles inside the slits, as a result of the ion etching. After deposition of $λ$ DNA molecules, using a protocol that we describe in detail, some of the slits became conducting and exhibited superconducting fluctuations at low temperatures. We argue that the observed conduction was due to transport along DNA molecules, that interacted with the Ga nanoparticles present in the slit. At low temperatures when Ga becomes superconducting, induced superconductivity could therefore be observed. These results indicate that minute metallic particles can easily transfer charge carriers to attached DNA molecules and provide a possible reconciliation between apparently contradictory previous experimental results concerning the length over which DNA molecules can conduct electricity.

In MRDM the patterns are available in multiple tables (relations) from a relational database. As the data are available over the many tables which will affect the many problems in the practice of the data mining. To deal with this problem, one either constructs a single table by Propositionalisation, or uses a Multi-Relational Data Mining algorithm. MRDM approaches have been successfully applied in the area of bioinformatics. Three popular pattern finding techniques classification, clustering and association are frequently used in MRDM. Multi relational approach has developed as an alternative for analyzing the structured data such as relational database. MRDM allowing applying directly in the data mining in multiple tables. To avoid the expensive joining operations and semantic losses we used the MRDM technique.

description: In this paper, the static compressive mechanical behaviors of carbon fiber reinforced composites (CFRP) single-lap bolted joints under anti-buckling test fixture were studied. Acoustic emission (AE) technology was used to monitor the damage evolution of specimens. X-ray micro-computed tomography (X-ray μCT) was used to evaluate the damage of CFRP single-lap bolted joints. The surface morphology of the holes was studied by field emission scanning electron microscopy (FESEM). An image processing and analyzing method was proposed, which allows the damage of the specimens to be accurately visualized, separated and quantified in 3D. The results show that X-ray μCT characterization technique greatly improves the ability to characterize the damage of CFRP single-lap bolted joints. The squeezing damage of the composite holes caused by the inclination of the bolt is an important factor affecting the bearing capacity of CFRP single-lap bolted joints.
The Ruins of Doves
Creators: name: Yusofzei, Mariah Tahera
Publisher: name: University of Nevada, Las Vegas
Year: 2019

description: The Ruins of Doves is a collection of 40 poems that attempts to access the conversational space for the poet's encounters with her environment, and correspondingly, with the divine. Keeping with this sentiment, each poem embodies a little song or prayer, where the poem itself acts as a gateway in attempting to understand the divine. Amid the quietness in the space of the poem is where the poet explores her relationship with the divine. An understanding of community, domestic love, and intimacy share a point of arrival where many of the poems begin. Each poem is an accumulation and a culmination of encounter and experience, in which time functions as a door of revolving opportunity, and the notion of "the hour" is beyond constraint in questioning our traditional idea and treatment of time. The poems provoke two central questions: How do we find intimacy and privacy when so much within our world has become so public and general? How do we seek unity in the idea of our private self and our public self? Though in asking these questions, the poet also seeks to become an expansion of her surroundings and questions boundaries or points of separation between herself and other creatures and elements of nature that are within observation. Many of the poems are oriented around the idea of twoness or multiplicity, in having an understanding that two beings can inhabit a single space or a single universe within time as separate beings who are whole in their singularity, yet who are also able to be joined together in the intimate space that is the poem. The poems are not intended to settle anything or to find resolution; they accrue within the livable space of the poem rather than seeking to mean.
Mean-Field Analysis of Spinor Bosons in Optical Superlattices

description: We study the ground-state phase diagram of spinless and spin-1 bosons in optical superlattices using a Bose-Hubbard Hamiltonian that includes spin-dependent interactions. We decouple the unit cells of the superlattice via a mean-field approach and take into account the dynamics within the unit cell exactly. The system supports Mott-insulating as well as superfluid phases. The transitions between these phases are second-order for spinless bosons and second- or first-order for spin-1 bosons. Anti-ferromagnetic interactions energetically penalize high-spin configurations and elongate all Mott lobes, especially the ones corresponding to an even atom number on each lattice site. We find that the quadratic Zeeman effect lifts the degeneracy between different polar superfluid phases leading to additional metastable phases and first-order phase transitions. Finally, we show that an energy offset between the two sites of the unit cell induces a staircase of single-atom tunneling resonances which surprisingly survives well into the superfluid regime.

description: For ball screw feed system on a lathe, the randomness of geometric parameters deriving from the inevitable manufacturing and assembly errors significantly affected the system dynamic characteristics and turning accuracy. In this study, a novel lumped dynamic model accounting for the analytical piecewise restoring force function involving the overall axial deformation is proposed. The equivalent mechanical model of bearing joints including the change of nominal contact angle is made a reasonable simplification to facilitate acquisition of the system analytical equation of motion. Additionally, the approximate analytical solution of the proposed equation is obtained by the modified Lindstedt–Poincaré method (MLP). The advanced first order second moment method (AFOSM) is employed to evaluate the reliability of dynamic response error. Furthermore, the numerical simulation aims to demonstrate the capabilities of the MLP and AFOSM method in the practical applications. Eventually, the effects of external excitation, sliding platform position, and nominal contact angles on the dynamic response are discussed and the reliability and sensitivity analysis in accordance with actual turning accuracy level is presented.

description: The competing spin orders and fractional magnetization plateaus of classical Heisenberg model with long-range interactions on a Shastry-Sutherland lattice are investigated using Monte Carlo simulations, in order to understand the fascinating spin ordering sequence observed in TmB4 and other rare-earth tetraborides. The simulation reproduces the experimental 1/2 magnetization plateau at low temperature by considering multifold long range interactions. It is found that more local long range interactions can be satisfied in the 1/2 plateau state than those in the 1/3 plateau state, leading to the stabilization of the extended 1/2 plateau. A mean-field theory on the spin ground states in response to magnetic field is proposed, demonstrating the simulation results. When the energies of the Neel state and the collinear state are degenerated, the former state is more likely to be stabilized due to the competitions among the local collinear spin orders. The present work provides a comprehensive proof of the phase transitions to the Neel state at nonzero temperature, in complimentary to the earlier predictions for the Fe-based superconductors.

description: The uncertainty in the absolute value of the air-fluorescence yield still puts a severe limit on the accuracy in the primary energy of ultra-high-energy cosmic rays. The precise measurement of this parameter in laboratory is in turn conditioned by a careful evaluation of the energy deposited in the experimental collision chamber. In this work we discuss on the calculation of the energy deposition and its accuracy. Results from an upgraded Monte Carlo algorithm that we have developed are compared with those obtained using Geant4, showing excellent agreement. These updated calculations of energy deposition are used to apply some corrections to the available measurements of the absolute fluorescence yield, allowing us to obtain a reliable world average of this important parameter.

description: Since the revolution emerged in North and East Syria (NES) in 2012, there has been much scholarly attention on democratic confederalism and the Autonomous Administration of North and East Syria (AANES, Rojava). Much of this literature has focused on its exceptional nature. Following Michel-Rolph Trouillot I ask, what is being obscured or masked when we assume and focus on the AANES as exceptional? To that aim, I uncover what North and East Syria (NES) reveals about sovereignty as an ideal and the production of what we recognize as a coherent hierarchical state system. Building on the analyses of Samir Amin and Andre Gunder Frank, I examine the constraints that decades of development of underdevelopment have placed on North and East Syria and on the Autonomous Administration. I ask four primary questions: [1] Can sovereignty exist beyond the state? And if so, what are the contradictions that emerge in a hierarchal state system? [2] How has this hierarchical state-system structured the counterhegemonic worldmaking project of democratic confederalism in NES? [3] How has the AANES sought to increase their legitimacy, to what audiences, and why? Upon what justifications, discourses, and venues do their bids rest? [4] What does this project reveal about sovereignty, the state, and the production of a coherent hierarchical state-system? Methodologically, I conduct semi-structured interviews with twelve people in NES and triangulate these interviews with current fieldwork and research being produced. This thesis is written in three sections. The first provides a genealogical background to the revolution. The second looks at the political economy and ecology of the Jazira. The third turns to three areas of investigation: the international peace process; international aid in a global pandemic; and the repatriation of ISIS fighters and their families. I argue that NES demonstrates that sovereignty beyond the state is possible. However, embedded in a hierarchical state system, this assertion of non-state sovereignty produces contradictions.

description: Legume roots can be symbiotically colonized by arbuscular mycorrhizal (AM) fungi and nitrogen-fixing bacteria. In Lotus japonicus, the latter occurs intracellularly by the cognate rhizobial partner Mesorhizobium loti or intercellularly with the Agrobacterium pusense strain IRBG74. Although these symbiotic programs show distinctive cellular and transcriptome signatures, some molecular components are shared. In this study, we demonstrate that 3-deoxy-d-arabino-heptulosonate 7-phosphate synthase 1 (DAHPS1), the first enzyme in the biosynthetic pathway of aromatic amino acids (AAAs), plays a critical role in root hair development and for AM and rhizobial symbioses in Lotus. Two homozygous DAHPS1 mutants (dahps1-1 and dahps1-2) showed drastic alterations in root hair morphology, associated with alterations in cell wall dynamics and a progressive disruption of the actin cytoskeleton. The altered root hair structure was prevented by pharmacological and genetic complementation. dahps1-1 and dahps1-2 showed significant reductions in rhizobial infection (intracellular and intercellular) and nodule organogenesis and a delay in AM colonization. RNAseq analysis of dahps1-2 roots suggested that these phenotypes are associated with downregulation of several cell wall-related genes, and with an attenuated signaling response. Interestingly, the dahps1 mutants showed no detectable pleiotropic effects, suggesting a more selective recruitment of this gene in certain biological processes. This work provides robust evidence linking AAA metabolism to root hair development and successful symbiotic associations.

description: We report optical and X-ray observations of the high-field polar RXJ1007.5-2017 performed between 1990 and 2012. It has an orbital period of 208.60 min determined from the ellipsoidal modulation of the secondary star in an extended low state. The spectral flux of the dM3- secondary star yields a distance of 790+-105 pc. At low accretion levels, \RX{} exhibits pronounced cyclotron emission lines. The second and third harmonic fall in the optical regime and yield a field strength in the accretion spot of 94 MG. The source is highly variable on a year-to-year basis and was encountered at visual magnitudes between V \sim 20 and V \sim 16. In the intermediate state of 1992 and 2000, the soft X-ray luminosity exceeds the sum of the luminosities of the cyclotron source, the hard X-ray source, and the accretion stream by an order of magnitude. An X-ray high state, corresponding to the brightest optical level, has apparently not been observed so far.

Nature of Lyman Alpha Blobs: Powered by Extreme Starbursts

description: We present a new model for the observed Lyman alpha blobs (LABs) within the context of the standard cold dark matter model. In this model, LABs are the most massive halos with the strongest clustering (proto-clusters) undergoing extreme starbursts in the high-z universe. Aided by calculations of detailed radiative transfer of Lya photons through ultra-high resolution (159pc) large-scale (>30Mpc) adaptive mesh-refinement cosmological hydrodynamic simulations with galaxy formation, this model is shown to be able to, for the first time, reproduce simultaneously the global Lya luminosity function and luminosity-size relation of the observed LABs. Physically, a combination of dust attenuation of Lya photons within galaxies, clustering of galaxies, and complex propagation of Lya photons through circumgalactic and intergalactic medium gives rise to the large sizes and frequently irregular isophotal shapes of LABs that are observed. A generic and unique prediction of this model is that there should be strong far-infrared (FIR) sources within each LAB, with the most luminous FIR source likely representing the gravitational center of the proto-cluster, not necessarily the apparent center of the Lya emission of the LAB or the most luminous optical source. Upcoming ALMA observations should unambiguously test this prediction. If verified, LABs will provide very valuable laboratories for studying formation of galaxies in the most overdense regions of the universe at a time when global star formation is most vigorous.

title: Innovative Biological Solutions for Nitrogen Fixation

description: Nitrogen is an important part of biological molecules like proteins and DNA and hence is essential for life as we know it. The most commonly found form of nitrogen is dinitrogen gas (N2) in the atmosphere, which is not accessible to most organisms. Conversion of N2 into a usable form (ammonia), occurs through an energy-demanding reaction called nitrogen fixation. As we think about sending humans to Mars, there is a need to develop technologies for nitrogen fixation to produce fertilizer and other valuable compounds to support life in those harsh conditions.
The Haber-Bosch process is used in industries on Earth to produce ammonia from N2 and H2 under 400-500◦C temperature and 150-250 atm pressure. While this has enabled low-cost fertilizer production on Earth, it is not sustainable and is impractical for manned missions to outer space. Some microorganisms can perform a similar reaction using an enzyme called nitrogenase. The biological process typically occurs under standard temperature and pressure and so is a more feasible and sustainable option. However, scalable biohybrid technologies are not well developed, especially for applications in outer space.
The overarching aim of this thesis is to lay the groundwork for biological technologies that can replace the industrial process and function in conditions where resources and nutrients are scarce. The work presented here will demonstrate a proof-of-concept system that can support bacterial growth by capturing both N2 and CO2 using low energy infra-red light, and H2 produced from water electrolysis. The bacterial culture generated can be utilized as a fertilizer for plant growth and food production, as well as support other microbes for production of bioplastics and pharmaceuticals.
Further, we developed a bacterial strain that can grow under low nitrogen concentrations (2% N2, compared to 78% in the Earth’s atmosphere). To our knowledge, this is this first time bacteria have been observed to grow with such low concentrations of N2. This strain will not only allow us to increase efficiencies of the hybrid system under conditions similar to Mars, but can also reveal genetic targets for further improvements. Taken together, these studies can help develop sustainable nitrogen fixation technologies for applications in outer space and may also provide a competitive alternative to the current industrial process on Earth.

description: Radio halos are elusive sources located at the center of merging galaxy clusters. To date, only about 40 radio halos are known, thus the discovery of new halos provide important insights on this class of sources. To improve the statistics of radio halos, we investigated the radio continuum emission in a sample of galaxy clusters. We analyzed archival Very Large Array observations at 1.4 GHz, with a resolution of about 1 arcmin. These observations complemented by X-ray, optical, and higher resolution radio data allowed to detect a new radio halo in the central region of A800 and A1550. We discovered a radio relic in the periphery of A910, and finally we revealed both a halo and a relic in CL1446+26.Clusters hosting these new halos show an offset between the radio and the X-ray peak. By analyzing this offset statistically we found that radio halos can be quite asymmetric with respect to the X-ray gas distribution, with an average radio - X-ray displacement of about 180 kpc. When the offsets are normalized by the halo size, there is a tendency for smaller halos to show larger displacements.

title: Teaching Distributed Application Design Using Drones
Creators: name: Frandsen, Cameron
Publisher: name: Utah State University
Year: 2020

description: This thesis provides a new platform that instructors can use to create a learning environment for students to learn how to design and implement distributed applications. One possible way to use the platform uses milestones to test the student’s understanding of different concepts. Milestones contain pretests that students can use to test their code. Each milestone focuses on a different concept, including interprocess communication, reliability, and security. A monitor process can be created by the students to provide away for the instructor to see how well the students are learning the concepts by using a monitor process. The platform gives control to the instructor to choose what skills, knowledge areas, and abilities are covered by an assignment. There are many valid solutions to the problem this platform provides, giving students the flexibility to design their system. The platform uses drones to create interest in the subject to more fully engage the students and better help them understand distributed systems. This thesis provides a sample implementation of the assignment to validate the platform. This thesis then compares this platform to other assignments in a project-based pedagogy for distributed systems using a new technique. This technique quantifies the effectiveness of each assignment dynamically, allowing instructors with different priorities to compare the assignments in different ways.
