description: We present a unified model for molecular core formation and evolution, based on numerical simulations of converging, supersonic flows. Our model applies to star formation in GMCs dominated by large-scale turbulence, and contains four main stages: core building, core collapse, envelope infall, and late accretion. During the building stage, cores form out of dense, post-shock gas, and become increasingly centrally stratified as the mass grows over time. When the shock radius defining the core boundary exceeds $R\approx 4 a (4πG ρ_{mean})^{-1/2}$, where $a$ is the isothermal sound speed, a wave of collapse propagates from the edge to the center. During the building and collapse stages, density profiles can be fit by Bonnor-Ebert profiles with temperature 1.2 - 2.9 times the true value. As found previously for initially static equilibria, outside-in collapse leads to a Larson-Penston density profile $ρ\approx 8.86 a^2/(4 πG r^2)$. The third stage, consisting of an inside-out wave of gravitational rarefaction leading to $ρ\propto r^{-3/2}$, $v\propto r^{-1/2}$, is also similar to that for initially-static spheres, as originally described by Shu. We find that the collapse and infall stages have comparable duration, $\sim t_{ff}$, consistent with estimates for observed prestellar and protostellar (Class 0/I) cores. Core building takes longer, but does not produce high-contrast objects until shortly before collapse. The time to reach core collapse, and the core mass at collapse, decrease with increasing inflow Mach number. For all cases the accretion rate is $\gg a^3/G$ early on but sharply drops off; the final system mass depends on the duration of late-stage accretion, set by large-scale conditions in a cloud.

description: Exploring large virtual environments, such as cities, is a central task in several domains, such as gaming and urban planning. VR systems can greatly help this task by providing an immersive experience; however, a common issue with viewing and navigating a city in the traditional sense is that users can either obtain a local or a global view, but not both at the same time, requiring them to continuously switch between perspectives, losing context and distracting them from their analysis. In this paper, our goal is to allow users to navigate to points of interest without changing perspectives. To accomplish this, we design an intuitive navigation interface that takes advantage of the strong sense of spatial presence provided by VR. We supplement this interface with a perspective that warps the environment, called UrbanRama, based on a cylindrical projection, providing a mix of local and global views. The design of this interface was performed as an iterative process in collaboration with architects and urban planners. We conducted a qualitative and a quantitative pilot user study to evaluate UrbanRama and the results indicate the effectiveness of our system in reducing perspective changes, while ensuring that the warping doesn't affect distance and orientation perception.

description: Starting from the students’ difficulties and frequent failures in their learning process, the following study discusses the mental restyling caused by the development of new technologies. The advent of new technologies led us to consider how important is the complexity of knowledge no more restricted to traditional linear criteria of sequencing, through which teachers still translate the complex knowledge, and how important is to take into account the advent of new technologies to introduce different strategies in the organization of information and in the learning process, developing a new critical attitude towards the study of modern media. In the paper there is the description of an experimentation in a classroom. It is similar to an imaginary voyage in the universe of media aiming at promoting a critical thoughtful thinking about the way in which the media work. It’s a way to discover the epistemic value of the psycho-technologies and the psychological value of the epistemic technologies so that the school becomes the space in which the pages of the book can dialogue with the pictures of the screen meeting and building a new logic, different from the book and different from the screen, but capable to integrate both and to create a new epistemology of transversality.

description: We present tracial analogs of the classical results of Curto and Fialkow on moment matrices. A sequence of real numbers indexed by words in non-commuting variables with values invariant under cyclic permutations of the indexes, is called a tracial sequence. We prove that such a sequence can be represented with tracial moments of matrices if its corresponding moment matrix is positive semidefinite and of finite rank. A truncated tracial sequence allows for such a representation if and only if one of its extensions admits a flat extension. Finally, we apply the theory via duality to investigate trace-positive polynomials in non-commuting variables.

Cation composition effects on oxide conductivity in the Zr_2Y_2O_7-Y_3NbO_7 system

description: Realistic, first-principles-based interatomic potentials have been used in molecular dynamics simulations to study the effect of cation composition on the ionic conductivity in the Zr2Y2O7-Y3NbO7 system and to link the dynamical properties to the degree of lattice disorder. Across the composition range, this system retains a disordered fluorite crystal structure and the vacancy concentration is constant. The observed trends of decreasing conductivity and increasing disorder with increasing Nb5+ content were reproduced in simulations with the cations randomly assigned to positions on the cation sublattice. The trends were traced to the influences of the cation charges and relative sizes and their effect on vacancy ordering by carrying out additional calculations in which, for example, the charges of the cations were equalised. The simulations did not, however, reproduce all the observed properties, particularly for Y3NbO7. Its conductivity was significantly overestimated and prominent diffuse scattering features observed in small area electron diffraction studies were not always reproduced. Consideration of these deficiencies led to a preliminary attempt to characterise the consequence of partially ordering the cations on their lattice, which significantly affects the propensity for vacancy ordering. The extent and consequences of cation ordering seem to be much less pronounced on the Zr2Y2O7 side of the composition range.

description: Many historical map sheets are publicly available for studies that require long-term historical geographic data. The cartographic design of these maps includes a combination of map symbols and text labels. Automatically reading text labels from map images could greatly speed up the map interpretation and helps generate rich metadata describing the map content. Many text detection algorithms have been proposed to locate text regions in map images automatically, but most of the algorithms are trained on out-ofdomain datasets (e.g., scenic images). Training data determines the quality of machine learning models, and manually annotating text regions in map images is labor-extensive and time-consuming. On the other hand, existing geographic data sources, such as Open- StreetMap (OSM), contain machine-readable map layers, which allow us to separate out the text layer and obtain text label annotations easily. However, the cartographic styles between OSM map tiles and historical maps are significantly different. This paper proposes a method to automatically generate an unlimited amount of annotated historical map images for training text detection models. We use a style transfer model to convert contemporary map images into historical style and place text labels upon them. We show that the state-of-the-art text detection models (e.g., PSENet) can benefit from the synthetic historical maps and achieve significant improvement for historical map text detection.

description: Context. Magnetic fields exhibit a wide variety of behaviours in low mass stars and further characterization is required to understand these observations. Stellar photometry from space missions such as MOST, CoRoT, Kepler, and, in future PLATO, provide thousands of highly precise light curves (LC) that can shed new light upon stellar activity, in particular through the signature of transiting spots. Aims. We study the impact of star spots on light curves in the Fourier domain, reducing the degeneracies encountered by direct spot modelling in the temporal domain, and use this new formulation to explore the spot properties from the available data. Methods. We propose a model of LC power spectra at low frequency based on a description of spot transits that allows us to retrieve information about the amplitude of their photometric impact $\mathcal{H}$, and about the spot mean lifetime over the observation $τ_{\rm life}$ when the power spectrum exibits rotation peaks. We first validate this method with simulated LCs and then apply it to the Kepler data to extract global trends over a set of more than 37 755 stars. Results. This analysis leads to a classification of the sample into "peakless" or "with peaks" spectra, and enables the identification of different activity regimes based on $\mathcal{H}$ and $τ_{\rm life}$ for different ranges of Rossby number. More specifically, we observe an intense regime of activity between Ro = 0.7 and Ro = 1, for stars with masses under 1$M_\odot$. Conclusions. This new systematic method can be used to provide new observational constraints on stellar activity (and possibly a link with stellar magnetism) when applied to large photometric datasets, such as those from the future PLATO mission.

description: «Ab sofort» – On 9 November 1989 the unexpected happened. After months of crisis, with tens of thousands of citizens fleeing the country through various means and routes, the government of the German Democratic Republic suddenly announced that it opened up the border crossings for travel to West Berlin forthwith.  Even diplomats, proficiently well-informed, had not seen this coming. Reactions by foreign envoys expressed concerns, warning of a ‘specter of German reunification’ that might upset the stability in Europe. Promoted by the West German government in Bonn, reunification became the keyword for all subsequent developments. Suddenly, agreements signed in 1945 took on a new immediacy. Yet four decades after the end of the war, the right of the German people to self-determination was beyond dispute. The rapid pace of developments presented challenges to foreign and German diplomats alike. This volume collects perspectives on German developments from eleven countries.

title: Historical Biogeography and Natural History of Nocturnal Wasps in the Southwestern Deserts with Special Emphasis on the Genus Chyphotes (Hymenoptera: Chyphotidae)
Creators: name: Sadler, Emily A.
Publisher: name: Utah State University
Year: 2018

description: Deserts are interesting places due to the large number of plants and animals that live there. Nocturnal wasps are extremely abundant in deserts, but they are difficult to identify and their life cycles are not well known especially the families of Chyphotidae, Tiphiidae (Brachycistidinae), and Mutillidae (velvet ants). In this dissertation, I determine how to correctly identify a particularly difficult group of species that all have black heads from the family Chyphotidae. This is important because these species make up a large proportion of specimens collected. Also, I expanded our knowledge on the distribution of the species of these three families of wasps by conducting a trap-transect study in Joshua Tree National Park catching 22 species of Brachyscistidinae based on the collection of 13,960 specimens, 11 species of Chyphotes based on the collection of 1,513 specimens and 35 species of velvet ants based on 8,447 specimens. From this study, three new species of velvet ants are described: Odontophotopsis dalyi Sadler and Pitts, sp. nov., O. odontoloxia Sadler and Pitts, sp. nov., and Photomorphus schoenwerthi Sadler and Pitts, sp. nov. Lastly, I used new molecular methods to determine relationships of the species of Brachyscistis, Chyphotes,  and Odontophotopsis. These relationships suggest that the species are young, which is contradictory to evidence based on birds and mammals. These relationships also support dates for the inundation of southern California by the Boues Sea Embayment and confirm a hypothesized Baja Inner Peninsular Seaway.
title: The Influence of Multiyear Drought-Driven Habitat Loss on the Bear Lake Sculpin (Cottus extensus) and the Bear Lake Strain of the Bonneville Cutthroat Trout (Oncorhynchus clarkii utah)
Creators: name: Glassic, Hayley C.
Publisher: name: Utah State University
Year: 2018

description: Multiyear drought is expected to increase in occurrence and severity in dry regions across the world, such as the American Southwest, endangering native species and ecosystem health. The effects of multiyear drought are often worsened by human water use for consumption, energy production, and agriculture, which, in lakes and reservoirs, cause reduced lake elevation. Reductions in lake elevation may leave previously submerged habitat stranded along shorelines and make tributaries inaccessible to fishes. Here, we show that decreasing lake elevation, associated with drought and water withdrawal, reduces the availability of shoreline cobble habitat to fishes and increases tributary distance by creating an elevation-specific shoreline habitat map and an elevation-specific tributary channel distance map, respectively. We combined 17-years of fish survey data and lake elevation history with our elevation-specific maps to determine whet her the number of fishes observed and the number of fish hatching are related to drought-driven changes in shoreline habitat and tributary channel distance. We surveyed the shoreline zone of Bear Lake, UT-ID, from full pool to a depth of >18m, totaling 94.86 surveyed km2. As lake elevation decreased >6 m from full pool to the lowest historical elevation, shoreline cobble decreased by >97%, and tributary channel distance increases up to 400% that of full pool. Bear Lake sculpin, a cold-water fish species of concern that relies on cobble for spawning, catch per unit effort decreased by >75% at the minimum cobble area available, and the number of sculpin successfully becoming adults declined by as much as 86%. The number of Bear Lake Bonneville cutthroat trout, a sport fish that relies on connections between tributaries and the lake to complete their life cycle, successfully becoming adults declined by as much as 62%, but annual growth was not related to drought. Our research is an example of the severe consequences of multiyear drought conditions and water withdrawal on lakes and reservoirs, as well as the fishes they support. Indeed, understand the effects of extended drought on aquatic habitats is critical to maintain healthy lakes and reservoirs, to sustain native species, and to maintain the health of popular sport fisheries.

title: Marginal Mediation Analysis: A New Framework for Interpretable Mediated Effects
Creators: name: Barrett, Tyson S.
Publisher: name: Utah State University
Year: 2018

description: Mediation analysis is built to answer not only if one variable affects another, but how the effect takes place. However, it lacks interpretable effect size estimates in situations where the mediator (an intermediate variable) and/or the outcome is categorical or otherwise non-normally distributed. By integrating a powerful approach known as average marginal effects within mediation analysis—termed Marginal Mediation Analysis (MMA)—the issues regarding categorical mediators and/or outcomes are, in large part, resolved. This new approach allows the estimation of the indirect effects (those effects of the predictor that affect the outcome through the mediator) that are interpreted in the same way as mediation analysis with continuous, normally-distributed mediators and outcomes. This also, in turn, resolves the troubling situation wherein the indirect plus the direct effect does not equal the total effect (i.e., the total effect does not equal the total effect). By offering this information in mediation, interventionists and lawmakers can better understand where efforts and resources can make the greatest impact. This project presents the development and the software of MMA, describes the evaluation of its performance, and reports an application of MMA to health data. The approach is successful in several aspects: 1) the software works across a wide variety of situations as the MarginalMediation R package; 2) MMA performed well and was statistically powered much like other mediation analysis approaches; and 3) the application demonstrated the increased amount of interpretable information that is provided in contrast to other approaches.

description: The decays of $χ_{cJ} \to π^+π^-, K^+K^-$ $(J=0,2)$ are discussed within the standard and modified hard scattering approach when including the contributions from twist-3 distribution amplitudes and wave functions of the light pseudoscalar meson. A model for twist-2 and twist-3 distribution amplitudes and wave functions of the pion and kaon with BHL prescription are proposed as the solution to the end-point singularities. The results show that the contributions from twist-3 parts are actually not power suppressed comparing with the leading-twist contribution. After including the effects from the transverse momentum of light meson valence-quark state and Sudakov factors, the decay widths of the $χ_{cJ}$ into pions or kaons are comparable with the their experimental data.

description: La presente investigación pretende determinar la naturaleza jurídica de los actos administrativos que establecen medidas de defensa comercial, partiendo de las generalidades teóricas de los conceptos sobre dumping, subvención y salvaguardia, y sobre las medidas específicas; para evidenciar como estas teorías aterrizan en los pronunciamientos de las autoridades colombianas que aplican dichas medidas y en la OMC, y así poder hacer un análisis del eco de estos en los actos administrativos que desde el estado colombiano se profieren como medidas de defensa comercial. La investigación así, dará alcance a la aplicación de las medidas, desde la perspectiva de la naturaleza jurídica del acto administrativo que las impone, los efectos jurídicos que genera para personas determinadas o indeterminadas, además de la responsabilidad del Estado por las consecuencias que pueda generar la imposición de estas y los mecanismos de defensa de los administrados frente a los mismos.
description: This investigation aims to determine the legal nature of the administrative acts that establish trade defense measures, starting from the theoretical generalities of the concepts of dumping, subsidy and safeguard, and the specific measures; to show how these theories land in the pronouncements of the Colombian authorities that apply these measures and in the WTO, and thus be able to analyze their echo in the administrative acts that the Colombian state prefers as trade defense measures. The investigation will thus give scope to the application of the measures, from the perspective of the legal nature of the administrative act that imposes them, the legal effects that it generates for certain or undetermined persons, in addition to the responsibility of the State for the consequences that it may generate. the imposition of these and the defense mechanisms of those administered against them.

description: In wildlife management, using cutting edge technology and science to monitor greater sage-grouse (Centrocercus urophasianus; sage-grouse) populations, enables land managers to better assess the impact of their management decisions. Having precise counts of sage-grouse lek attendance, and specifically male lek attendance, is an important metric used to evaluate population status and response to conservation actions (Gifford et.al, 2013, Dahlgren et al., 2016). Leks are seasonal breeding sites where males perform a ritualistic courtship dance for females.
Our case study examined if a Remotely Piloted Aircraft (RPA) was effective in detecting, and counting, sage-grouse during the lek season (early March to late April). More specifically, this research used a Forward-Looking Infrared (FLIR) camera (a thermal camera) to detect sage-grouse and determine body temperatures of individual sage-grouse to determine if temperature data can be used to identify displaying male sage-grouse. These images can be used to document the activity and behavior of sage-grouse and can be revisited at future times to document changes in bird numbers as well as perform additional statistical analyses. We conducted 5 flights and on a per-flight basis, we identified an average of 4.4 displaying males, 13.4 non-displaying males, and 5.6 female sage-grouse. We found that the average size and average maximum temperature of the three sage-grouse categories differed where females were smaller with an average body size of 325 cm2, an average maximum temperature of 14.6 C ̊, and a smaller average thermal range of 2.47 C ̊. Non-displaying male body size was approximately 488 cm2, with a maximum average temperature of 17.2 C ̊, and an average thermal range of 4.66C ̊. Displaying male body size was the largest at approximately 655 cm2, an average maximum temperature of 27.5C ̊, with the largest average range of 12.39C ̊. Our study demonstrates that RPA and infrared technology can be used to conduct accurate sage-grouse lek attendance counts. Further, results of this study will also provide a guideline for the use of RPA’s to monitor sage-grouse and other lekking species.

description: We explored simultaneous observations of chromospheric evaporation and condensation during the impulsive phase of a C6.7 flare on 9 May 2019. The solar flare was simultaneously observed by multiple instruments, i.e., the New Vacuum Solar Telescope (NVST), the Interface Region Imaging Spectrograph, the Atmospheric Imaging Assembly (AIA), the Fermi, the Mingantu Spectral Radioheliograph, and the Nobeyama Radio Polarimeters. Using the single Gaussian fitting and the moment analysis technique, redshifted velocities at slow speeds of 15-19 km/s are found in the cool lines of C II and Si IV at one flare footpoint location. Red shifts are also seen in the H-alpha line-of-sight (LOS) velocity image measured by the NVST at double footpoints. Those red shifts with slow speeds can be regarded as the low-velocity downflows driven by the chromospheric condensation. Meanwhile, the converging motions from double footpoints to the loop top are found in the high-temperature EUV images, such as AIA 131 A, 94 A, and 335 A. Their apparent speeds are estimated to be roughly 126-210 km/s, which could be regarded as the high-velocity upflows caused by the chromospheric evaporation. The nonthermal energy flux is estimated to be about 5.7x10^10 erg/s/cm^2. The characteristic timescale is roughly equal to 1 minute. All these observational results suggest an explosive chromospheric evaporation during the flare impulsive phase. While a HXR/microwave pulse and a type III radio burst are found simultaneously, indicating that the explosive chromospheric evaporation is driven by the nonthermal electron.

description: We investigate 35 pre-stellar cores and 36 proto-stellar cores in the Perseus molecular cloud. We find a very tight correlation between the physical parameters describing the N2H+ and NH3 gas. Both the velocity centroids and the line widths of N2H+ and NH3 correlate much better than either species correlates with CO, as expected if the nitrogen-bearing species are probing primarily the dense core gas where the CO has been depleted. We also find a tight correlation in the inferred abundance ratio between N2H+ and para-NH3 across all cores, with N(p-NH3)/N(N2H+)= 22 +/- 10. We find a mild correlation between NH3 (and N2H+) column density and the (sub)millimeter dust continuum derived H2 column density for pre-stellar cores, N(p-NH3)/N(H2) ~ 10e-8, but do not find a fixed ratio for proto-stellar cores. The observations suggest that in the Perseus molecular cloud the formation and destruction mechanisms for the two nitrogen-bearing species are similar, regardless of the physical conditions in the dense core gas. While the equivalence of N2H+ and NH3 as powerful tracers of dense gas is validated, the lack of correspondence between these species and the (sub)millimeter dust continuum observations for proto-stellar cores is disconcerting and presently unexplained.

title: Application of Machine Learning and Statistical Learning Methods for Prediction in a Large-Scale Vegetation Map

description: Original analyses of a large vegetation cover dataset from Roosevelt National Forest in northern Colorado were carried out by Blackard (1998) and Blackard and Dean (1998; 2000). They compared the classification accuracies of linear and quadratic discriminant analysis (LDA and QDA) with artificial neural networks (ANN) and obtained an overall classification accuracy of 70.58% for a tuned ANN compared to 58.38% for LDA and 52.76% for QDA. Because there has been tremendous development of machine learning classification methods over the last 35 years in both computer science and statistics, as well as substantial improvements in the speed of computer hardware, I applied five modern machine learning algorithms to the data to determine whether significant improvements in the classification accuracy were possible using one or more of these methods. I found that only a tuned gradient boosting machine had a higher accuracy (71.62%) that the ANN of Blackard and Dean (1998), and the difference in accuracies was only about 1%. Of the other four methods, Random Forests (RF), Support Vector Machines (SVM), Classification Trees (CT), and adaboosted trees (ADA), a tuned SVM and RF had accuracies of 67.17% and 67.57%, respectively. The partition of the data by Blackard and Dean (1998) was unusual in that the training and validation datasets had equal representation of the seven vegetation classes, even though 85% of the data fell into classes 1 and 2. For the second part of my analyses I randomly selected 60% of the data for the training data and 20% for each of the validation data and test data. On this partition of the data a single classification tree achieved an accuracy of 92.63% on the test data and the accuracy of RF is 83.98%. Unsurprisingly, most of the gains in accuracy were in classes 1 and 2, the largest classes which also had the highest misclassification rates under the original partition of the data. By decreasing the size of the training data but maintaining the same relative occurrences of the vegetation classes as in the full dataset I found that even for a training dataset of the same size as that of Blackard and Dean (1998) a single classification tree was more accurate (73.80%) that the ANN of Blackard and Dean (1998) (70.58%). The final part of my thesis was to explore the possibility that combining several of the machine learning classifiers predictions could result in higher predictive accuracies. In the analyses I carried out, the answer seems to be that increased accuracies do not occur with a simple voting of five machine learning classifiers.

title: Effect of High Intensity Ultrasound on the Crystallization Behavior of Interesterified Fats

description: The process of partial hydrogenation produces trans fats and the fats that undergo this process are called partially hydrogenated fats (PHF). Clinical studies have shown a strong association between PHF and coronary heart diseases. In 2015 The U.S. Food and Drug Administration removed the Generally recognized as safe or "GRAS" status of PHF. These fats were used in confectionary, margarines, shortenings, doughnuts, cookies, cakes, etc. The PHF serve a function in food by providing a higher shelf life and a desired harder structure due to their higher melting point. Hence, the food industry is currently looking for PHF alternatives which serve the function but have no harmful health effects. One of the alternatives to replace PHF is to use interesterified fats that have a low level of saturation that makes them healthier. However, these new fats are too soft with restricted use in many food applications. In this study, we explored the use of high intensity ultrasound (HIU) to improve the functional properties of interesterified fats and make them harder. Our study showed that HIU formed small crystals in these fats and increased their viscosity. The results from this study on the flavor release from the interesterified fats showed that the physical structure and hence the amount of solid fat in the sample affected its flavor perception. The solid fats had higher flavor perception than the liquid fat samples. The goal of this study is to improve the functionality of the interesterified fats using HIU and understand the flavor release from these fats to make substitution in food products easier.

description: According to environmental justice, environmental degradation and benefits should not be disproportionately shared between communities. Identifying disparities in the spatial distribution of environmental degradation is therefore a prerequisite for validating the state of environmental justice in a geographic region. Under ideal circumstances, environmental risk assessment is a preferred metric, but only when exposure levels have been quantified reliably after estimating the risk. In this study, we adopt a proximity burden metric caused by adjacent hazardous sources, allowing us to evaluate the environmental burden distribution and vulnerability to pollution sources. In close collaboration with a predominantly Latinx community in Chicago, we highlight the usefulness of our approach through a case study that shows how certain community areas in the city are likely to bear a disproportionate burden of environmental pollution caused by industrial roads.
