Seismic model

description: Continuous data from the Apollo Passive Seismic Experiment (PSE) were recorded from 1969 to 1977 at four sites on the lunar surface. These data have subsequently been used to generate nine unique one-dimensional seismic velocity models for the moon. In spite of the fact that these models were generated from the same data set, significant differences exist between them. We analyzed travel-time and waveform effects of these previously published seismic velocity models. In order to examine the predictive power of lunar seismic models currently in existence, we calculated the mean squared error between the predicted travel times of direct P- and S-waves for each and four published catalogs of seismic arrival time readings. The mean squared error of P-wave arrival times are smaller than that of S-wave arrival times for each model. Models typically fit artificial impacts, meteoroid impacts, and deep moonquakes better then shallow moonquakes. We found no systematic variation in travel times based on location of seismic station. We constructed a new model (referred to as YY13) of the lunar interior based on a weighted average of the other models with respect to how well they predict measured travel times. The YY13 model provides the least misfit based on all available lunar seismic data. In addition, we reprocessed a total of 85,466 moonquake traces recorded by the PSE and calculated the coda decay rate separately for shallow and deep events. Shallow events show relatively longer codas than deep events. We computed synthetic seismograms for the YY13 mode and alternative versions of this with a varying thickness low velocity zone at the surface. By comparing synthetic seismograms with original data, it is challenging to reproduce the long seismic coda inherent in all lunar seismograms with a single low velocity or thin scattering layer as suggested by previous efforts.

description: The search for compact components of strong ($S_{int} \ge 5$ Jy at 102.5 MHz) discrete radio sources from the Pushchino catalogue was carried out using the method of interplanetary scintillation. A total of 3620 sources were examined, and 812 of them were found to compact (scintillating) components. Estimates of fluctuations of the flux density of these compact components were derived from the scintillation index ($m_{max}$) corresponding to an elongation of $25^o$. The angular size and compactness of 178 sources with compact components were estimated. Scintillation indices of sources corresponding to the compact component ($m_{max}$) and flux densities of compact components were determined. It was demonstrated that slow variations of the spatial distribution of interplanetary plasma, which are related to the 11-year cycle of solar activity, may exert a systematic influence on the estimates of angular sizes of sources. Coefficients compensating the deviation from the spherical symmetry of solar wind in the estimates of angular sizes were found using the coefficient of asymmetry of the statistical distribution of intensity fluctuations. The study of correlations between the parameters of sources in the sample revealed that the maximum value of the scintillation index decreases as the integrated flux increases, while the angular size has no marked dependence on the integrated flux.

description: This dissertation explored and developed technologies for silicon based spin lattice devices. Spin lattices are artificial electron spin systems with a periodic structure having one to a few electrons at each site. They are expected to have various magnetic and even superconducting properties when structured at an optimal scale with a specific number ѵ of electrons. Silicon turns out to be a very good material choice in realizing spin lattices. A metal-oxide-semi conductor field-effect nanostructure (MOSFENS) device, which is closely related to a MOS transistor but with a nanostructured oxide-semi conductor interface, can define the spin lattices potential at the interface and alter the occupation ѵ with the gate electrode potential to change the magnetic phase. The MOSFENS spin lattices engineering challenge addressed in this work has come from the practical difficulty of process integration in modifying a transistor fabrication process to accommodate the interface patterning requirements. Two distinct design choices for the fabrication sequences that create the nanostructure have been examined. Patterning the silicon surface before the MOS gate stack layers gives a "nanostructure first" process, and patterning the interface after forming the gate stack gives a "nanostructure last process." Both processes take advantage of a nano-LOCOS (nano-local oxidation of silicon) invention developed in this work. The nano-LOCOS process plays a central role in defining a clean, sharp confining potential for the spin lattice electrons.

Newborn Screening Stategies for Disorders of Creatine Metabolism
Creators: name: Bentley, Rebecca L.
Publisher: name: University of Utah
Year: 2014

description: Creatine is necessary to transfer energy between cellular compartments. Creatine is converted to phosphocreatine by the creatine kinase reaction within mitochondria and phosphocreatine generates adenosine triphosphate (ATP) in the cytoplasm. ATP powers most of the energy consuming reactions in cells. Defects in creatine synthesis or transport disrupt this process and result in brain creatine deficiency syndromes. Affected patients have developmental delay, hypotonia, autism, seizures, and impaired motor skill development. Defects of creatine synthesis are caused by impaired activity of the enzymes guanidinoacetate methyltransferase (GAMT) and arginine:glycine amidinotransferase (AGAT), both transmitted as autosomal recessive traits, whereas defect in creatine transport (SLC6A8 Gene) are transmitted in an X-linked recessive manner. Patients with defects in creatine synthesis respond to creatine supplementation and dietary manipulations. This therapy is more effective if initiated before mental retardation is evident. For this reason, diagnosis should be accomplished as soon as possible with newborn screening. Here we report a reliable three-tier testing method for screening for GAMT and AGAT deficiency in newborns' v blood spots. Creatine and guanidinoacetate are detected in newborn screening blood spots by tandem mass spectrometry (MS/MS). Secondtier testing using LC-MS/MS confirms more quantitatively low creatine and increased or decreased guanidinoacetate levels, while third-tier testing consists of DNA sequencing to identify mutations in the GAMT and AGAT Genes. This test can potentially identify newborns with GAMT and AGAT deficiencies with low false positive rate and could be applied to newborn screening nationwide.
Government accountability reports and public education policy: studying political actors' decision-making

Political actors

description: This study asks how government accountability reports are used to influence public education policy. Government accountability reports, called "audits" in Utah, prove to be useful tools for examining education policy. Using a collective case study design examining Utah's Class Size Reduction (CSR) policy, government accountability reports demonstrate that a systematic review of request, report, and result is an effective means for identifying policy narratives. These government accountability reports showed that over 10 years Utah's State Office of Education and local school districts repeatedly failed to comply with Utah Statutes requiring accounting for CSR appropriations. Repeated findings of data integrity and poor accounting did not lead to political action by state legislators. Despite repeated negative findings about CSR expenditures legislative appropriations were maintained even during two economic downturns. Evidence in this study suggests that these reports result from a breakdown in communication between agency officials and the Legislature. Government accountability reports do not appear to have any more influence on policy decision-making than other sources of policy information. However, these sources of information are financed with public dollars, and political actors' dissatisfaction with agency responses does not justify the cost of unused reports.

Mining project evaluation process for investment decisions

description: Mining and the related industries play an important role in the Korean economy. The Korean mining industry is relatively small. There are several mines in Korea but they are very small, and production is low in comparison with other countries' mines. Thus Korea must take part in mineral projects all over the world to secure essential minerals such as coal, copper, uranium, iron ore, zinc, and nickel to support its manufacturing industries. For that reason, the Korean government established K  Company1 as a government corporation to invest in mineral deposits throughout the world. However there are several major entities, including BHP Billiton, Rio Tinto, Anglo American, Xstrata, Freeport McMoRan, Chinese government-run companies, and Japanese trading companies that have large foreign holdings, controlling deposits in most of the world's established and productive mining districts. As a relative newcomer, K Company is having difficulty breaking into these markets.  In general, the mining industry considers the United States, Canada, Australia, and European countries to have good mining investment environments, but because the major companies have already achieved market dominance in those countries large investments  are required. Thus K Company is increasingly turning to new areas like South America (Peru and Bolivia) and Africa. The competition among businesses to secure a share of the new market is intense but there are still good investment opportunities. However, because  most of the countries in these areas are not well developed, there are several additional risks associated with participation in mining projects there.  Risk is a major factor in all mining activities, arising from many internal and external variables. In this thesis, those variables are identified, and their effects evaluated, based on a survey of 31 experts. A statistical model to analyze the effect of risk on the economic feasibility of mine development and operation at a given location is presented, and validated using analysis from projects at K Company. The guidelines and model, as  presented here, will enable K Company and other investors to make better investment decisions in the future.
Photometric survey of the red giant V449 Cygni over half a century (1974 to 2022). A semi-regular variable star with a period of ~54 days

description: This study sums up a major part of the red giant V449 Cygni measurements for the years 1974 through 2022, obtained by visual and CCD GEOS observers, the Unione Astrofili Italiani, and various automatized telescopes. It appears that the light variations of V449 Cyg in the years 1970-1990 corresponded more to an L-type star according to the GCVS classification, with irregular amplitude variations, sometimes marked by a quasi-periodicity of about 100 days. Since the mid-1990s, these variations have become more regular, with an amplitude of about 0.7 magnitude in V, and a period of about 54,1 days, as shown by various period search routines applied to the best recent CCD series. A longer period of about 2000 days is possible to describe the long term variation of V449 Cyg. Therefore, V449 Cyg appears to be an SRB-type star.

description: This study proposes a one-shot data-driven tuning method for a fractional-order proportional-integral-derivative (FOPID) controller. The proposed method tunes the FOPID controller in the model-reference control formulation. A loss function is defined to evaluate the match between a given reference model and the closed-loop response while explicitly considering the closed-loop stability. A loss function value is based on the fictitious reference signal computed using the input/output data. Model matching is achieved via loss function minimization. The proposed method is simple and practical: it needs only one-shot input/output data of a plant (no plant model required), considers the bounded-input bounded-output stability of the closed-loop system from a bounded reference input to a bounded output, and automatically determines the appropriate parameter value via optimization. Numerical simulations show that the proposed approach facilitates good control performance, and destabilization can be avoided even if perfect model matching is unachievable.

description: With the increasing need for multi-robot for exploring the unknown region in a challenging environment, efficient collaborative exploration strategies are needed for achieving such feat. A frontier-based Rapidly-Exploring Random Tree (RRT) exploration can be deployed to explore an unknown environment. However, its' greedy behavior causes multiple robots to explore the region with the highest revenue, which leads to massive overlapping in exploration process. To address this issue, we present a temporal memory-based RRT (TM-RRT) exploration strategy for multi-robot to perform robust exploration in an unknown environment. It computes adaptive duration for each frontier assigned and calculates the frontier's revenue based on the relative position of each robot. In addition, each robot is equipped with a memory consisting of frontier assigned and share among fleets to prevent repeating assignment of same frontier. Through both simulation and actual deployment, we have shown the robustness of TM-RRT exploration strategy by completing the exploration in a 25.0m x 54.0m (1350.0m2) area, while the conventional RRT exploration strategy falls short.

description: We consider quantum computer architectures where interactions are mediated between hot qubits that are not in their mechanical ground state. Such situations occur, e.g., when not cooling ideally, or when moving ions or atoms around. We introduce quantum gates between logically encoded systems that consist of multiple physical ones and show how the encoding can be used to make these gates resilient against such imperfections. We demonstrate that, in this way, one can improve gate fidelities by enlarging the logical system, and counteract the effect of unknown positions or position fluctuations of involved particles. We consider both a classical treatment of positions in terms of probability distributions, as well a quantum treatment using mechanical eigenmodes. We analyze different settings including a cool logical system mediating interactions between two hot systems, as well as two logical systems consisting of hot physical systems whose positions fluctuate collectively or individually. In all cases, we demonstrate a significant improvement of gate fidelities, which provides a platform-independent tool to mitigate thermal noise.

Utilization

description: In spite of the demonstrated accuracy of modern hematology analyzers, many laboratories repeat critical and delta results. No studies have evaluated the efficacy of repeating these results. Manual review of blood smears is a practice with considerable variability and also poorly studied. In this study we evaluated the analytical yield from repeating samples, and the efficacy of the criteria that trigger slide review and manual differentials. A retrospective analysis of approximately 2000 consecutive, repeated results were compared graphically and statistically. Approximately 1500 patients slides reviewed according to current institutional criteria were retrospectively evaluated according to the International Consensus Group for Hematology Review (ICGHR) criteria. Another 500 samples were reviewed prospectively to evaluate the relative efficiencies of the ICGHR and current review criteria. A survey tool assessing current review and repeat practices was sent to a sample of U.S. laboratories. The analytical yield for repeat analysis was negligible. Survey results revealed that 68.2% of laboratories always repeat critical results, while only 39.7 % always repeat delta results.  A significant proportion of laboratories were not aware of the ICGHR review criteria (35.3 %). Application of the ICGHR review criteria would have reduced the number of manual differentials performed, but not the fraction of smears reviewed. Repeat analysis of critical and delta results is highly inefficient and unnecessary. Wide application of the ICGHR review criteria would reduce the number of manual differentials performed in laboratories.

description: Social media data is a valuable resource for research, yet it contains a wide range of non-standard words (NSW). These irregularities hinder the effective operation of NLP tools. Current state-of-the-art methods for the Vietnamese language address this issue as a problem of lexical normalization, involving the creation of manual rules or the implementation of multi-staged deep learning frameworks, which necessitate extensive efforts to craft intricate rules. In contrast, our approach is straightforward, employing solely a sequence-to-sequence (Seq2Seq) model. In this research, we provide a dataset for textual normalization, comprising 2,181 human-annotated comments with an inter-annotator agreement of 0.9014. By leveraging the Seq2Seq model for textual normalization, our results reveal that the accuracy achieved falls slightly short of 70%. Nevertheless, textual normalization enhances the accuracy of the Hate Speech Detection (HSD) task by approximately 2%, demonstrating its potential to improve the performance of complex NLP tasks. Our dataset is accessible for research purposes.

Shear resistance

description: Corrosion of traditional steel reinforcement used in reinforced concrete bridges and parking structures exposed to water and deicing salts is of major concern. The chloride-induced corrosion of traditional steel reinforcement weakens the reinforced concrete member as well as adding to the annual maintenance cost of the structure. The resistance to corrosion of Glass Fiber Reinforced Polymer (GFRP) bars as reinforcement  provides a viable alternative to steel reinforcement in areas where deterioration of steel reinforcement is an issue. Additional benefits can be obtained through the use of lightweight concrete. Lightweight concrete can allow structural members to be lighter, which is advantageous for lifting and moving operations when precast concrete elements are used. This thesis evaluates the one-way shear capacity of precast lightweight concrete panels reinforced with GFRP reinforcement. A total of six precast concrete  specimens consisting of three normal weight concrete specimens and three lightweight concrete specimens reinforced with GFRP reinforcement were tested and compared. Finally, the results are compared to the theoretical shear predictions of the ACI 440.1R-  06 and those provided by previous research conducted by Mr. Neil Hoult of the University of Cambridge, UK.

Vegetation classification

description: Hyperspectral data covering the visible, near infrared, and shortwave infrared portions of the electromagnetic spectrum have been used to map vegetation at the plant  functional type and species levels in a variety of ecosystems. Vegetation maps are basic to the study and analysis of natural resources and are an important component in documenting and understanding the impacts of environmental changes in ecosystems due  to human-induced changes (e.g., climate change). Multiple methods for mapping vegetation have been developed to take advantage of the large number of bands (> 200) and spectral contiguity that hyperspectral data provide. The purpose of this study is to determine what the limitations and potential areas of success are for using hyperspectral remote sensing data to classify vegetation cover in steep mountainous terrain at the plant functional type level.

description: The principle of maximum ignorance posits that the coarse-grained description of a system is maximally agnostic about its underlying microscopic structure. We briefly review this principle for random matrix theory and for the eigenstate thermalization hypothesis. We then apply this principle in holography to construct ensembles of random mixed states. This leads to an ensemble of microstates which models our microscopic ignorance, and which on average reproduces the effective semiclassical physics of a given bulk state. We call this ensemble the state-averaging ansatz. The output of our model is a prediction for semiclassical contributions to variances and higher statistical moments over the ensemble of microstates. The statistical moments provide coarse-grained -- yet gravitationally non-perturbative -- information about the microstructure of the individual states of the ensemble. We show that these contributions exactly match the on-shell action of known wormhole configurations of the gravitational path integral. These results strengthen the view that wormholes simply parametrize the ignorance of the microstructure of a fundamental state, given a fixed semiclassical bulk description.

description: Intrauterine growth restriction (IUGR) is associated with a multitude of  complications including an increased risk of developing adult insulin resistance. The  mechanism behind this increased risk likely stems from epigenetic modifications. Acid  labile subunit (ALS) is responsible for regulating the tissue bioavailability of IGF-1. IGF-1  bioavailability is vital in regulating myriad of functions, including adult glucose regulation.  In this study western blotting was used to compare serum levels of ALS in IUGR  rats to that of control animals. In addition, STAT5 occupancy of GH-response elements  found in association with ALS and IGF-1 was used as a means of developing a chromatin  immunoprecipitation (ChIP) assay to facilitate further exploration into the interactions  between transcription factors and chromatin. Serum ALS protein levels were significantly  increased in female rats at day 21 and at day 120. ALS serum protein levels in males were  not significantly different in control and IUGR animals. Development of a fast ChIP assay  gave some preliminary insight into differential occupancy of GH-response elements, by  STAT5, where it appears that in female IUGR tissue there is a shift in occupancy toward  the ALS regulatory element and away from one of the IGF-1 regulatory elements. In  conclusion, it appears that female IUGR animals have greater levels of serum ALS and a  potential shift in STAT5 binding of the ALS and IGF-1 response elements in favor of ALS  expression. The improved ChIP assay reported here should help facilitate further  investigation into the transcriptional regulation of ALS, IGF-1 and other important genes.

description: It has been established that the famous three-dimensional Thurston geometries have four intrinsically Lorentzian analogs. We explore these spacetimes in three-dimensional general relativity nonminimally coupled to a scalar field together with electromagnetic matter. We find that three of these spacetimes support electromagnetic radiation, while, the other is partially sourced by a nonnull field and supports gravitational radiation. By addressing this problem we have also found a novel type of gravitational Cheshire effect.

description: Surface integrity plays a very important role in the life and functionality of machined surfaces used in a variety of engineering applications. Manufacturing processes and their sequence, along with the selection of cutting conditions and cutting tools, eventually dictate the type of surface that is being produced. Surface integrity is subdivided into several components, of which, some important components are surface roughness, residual stresses and subsurface microstructures. Enhanced understanding of all these factors and their interactions will potentially lead to advanced knowledge driven machining process planning. This thesis focuses on an experimental investigation of the effects of cutting tool coatings and cutting fluid application on surface integrity (residual stress, surface roughness and subsurface microstructure) in machined Ti6Al4V titanium alloy. For measuring residual stresses, the hole drilling method was used in this thesis research. The tools selected for the machining were uncoated flat-faced, uncoated grooved, multilayered (TiCN/Al2O3/TiN) CVD coated grooved, and single-layered (TiAlN) PVD coated grooved tools with tungsten carbide substrates. Three different cutting fluid application conditions were used namely: dry, minimal quantity lubrication (MQL) and flood. To illustrate the significance of this thesis, it was observed that a grooved multilayered CVD coated cutting tool under the influence of MQL condition, induced the highest near-surface residual stresses; on the other hand, the same tool, when machined under dry condition, produced the lowest residual stresses. Thus, it can be seen that a specific cutting tool material and/or geometry produce significantly different surface integrity when it is combined with different cutting fluid application conditions. Moreover, the microstructural analysis performed on these machined workpieces revealed significant changes in the subsurface microstructure with respect to the type of cutting tool-cutting fluid application combination used and correlated strongly with the measured residual stress profiles. The combined effect of the type of cutting tool along with the type of cutting fluid application condition on surface integrity is extremely significant. The results and findings o f this thesis have the potential to aid in choosing the combination of the cutting tool and the cutting fluid application that are best suited for machining. Apart from that, this thesis also provides several recommendations for future research on the fundamentals of the interactions between machining parameters such as tool coatings, tool geometry and cutting fluid applications and their significant effects on the generated surface integrity and the life of the component there after.

description: In a recent paper [arXiv:2308.00038], Anupam, Chowdhury, and Sen conjectured that the finite temperature Euclidean five-dimensional Cvetic-Youm solution saturating the BPS bound is supersymmetric. In this paper, we explicitly construct Killing spinors for this solution in five-dimensional minimal supergravity. We also expand on the previous discussions of Killing spinors for the finite temperature Euclidean Kerr-Newman solution saturating the BPS bound. For both these cases, we show that the total charge gets divided into two harmonic sources on three-dimensional flat base space.

description: This study examines the early Muslim immigrants' challenges of adaptation to and assimilation into the American mainstream society in the Salt Lake Valley in Utah. It finds that some Muslims in the pre-1965 era accepted the melting pot notion of total assimilation as the Americanization process, e.g., Moses Kader's family. Others rejected total assimilation, choosing not to lose their original identity. They lived in isolation as outsiders for decades before they finally returned to their home countries, e.g., Darwish and Ismael Kader.

Using incremental filtering for enhancing the depth perception of interactive direct volume rendering

description: In this dissertation a group of interactive volumetric rendering algorithms are presented that aim to increase the effectiveness of visualizations of scientific data sets arising in many varied fields such as radiology, chemistry or simulations of physical phenomena.  Interactivity is an important aspect of a visualization system since it permits rapid exploration and visual analysis of the relevant data sets and as such avoiding costly pre-computations is of key importance. The volume shading methods presented in this dissertation were designed to account for this and to enable interactive visualizations of volumetric and geometric data sets by exploiting the parallel computing powers available on modern graphics processing units.  The presented volumetric directional occlusion shading method allows computation of a subset of the global ambient occlusion solution by restricting the occlusion computation to a viewer oriented cone. This enables an efficient implementation in a slice-based direct  volume rendering system, while at the same time providing plausible depth cues similar to those of a full ambient occlusion computation.  The presented rendering of combined occlusion effects from both volumetric and geometric structures extends the benefits of enhanced depth perception to data sets combining geometry and volumes. Those originate in many varied fields of scientific visualization, where tube shaped structures are situated within an associated scalar volume. Common examples are DTI fiber tractography or streamline tracing.  The method for computing depth of field effects presented in this dissertation supports an alternative way of providing supplementary depth cues within the context; of direct volume rendering. They are especially useful for data sets, such as those arising from combustion simulation, where the presented occlusion shading method is less effective due to lack of sufficiently opaque, surface-like structures.  This dissertation also discusses a GPU implementation of a recently presented analytical scattering model which enables the computation of single scattering effects in homogeneous participating media with anisotropic phase functions and light distributions. The interactive  computation of those scattering effects are used in interactive entertainment applications to compute volumetric lighting, but also in programs that simulate visibility of traffic signs under adversary visibility conditions, such as smoke, fog or heavy rain.
