description: The novelty of additive manufacturing (AM) involves new requirements, restrictions and rules, that are considerably different to those of conventional manufacturing methods. Therefore, designers often lack experience and knowledge about identifying AM-suited components. However, to ensure profitability, it is essential to choose components, that are well suited for additive manufacturing. State-of-the-art user-support methods for identifying AM potential widely focus on either economic potential or manufacturability but fail to address both aspects. While machine learning solutions are considered highly efficient, the assessment outcome lacks process transparency, inhibiting troubleshooting, plausibility checks and problem-oriented considerations. This paper proposes a holistic, yet detailed and transparent approach to identify conventionally manufactured parts for AM from an existing product portfolio, enabling decision-making based on quantifiable results. It combines and advances state-of-the-art methods, considering manufacturability, economic profitability and socio-ecological aspects. Besides evaluating AM potential, the method additionally assesses the components' potential for re-design-based enhancement for AM suitability. Besides understanding product functions and present production processes, users are expected to have a basic understanding of company goals. The approach involves inquiries regarding company- and product-specific priorities, enabling a weighted assessment. The weights are determined based on individual company philosophies regarding AM value propositions such as differing stakeholder interests and priorities. Additionally, the approach allows users to investigate different development goals by weighting opportunistic and restrictive assessment. The method application is demonstrated via an assembly comprising 11 parts in a scenario focusing on serviceability, eventually determining suitability statements.

description: The Kondo effect in the system consisting of a magnetic adatom on the graphene is studied. By using the non-equilibrium Green function method with the slave-boson mean field approximation, the local density of state (LDOS) and the conductance are calculated. For a doped graphene, the Kondo phase is present at all time. Surprisingly, two kinds of Kondo regimes are revealed. But for the undoped graphene, the Kondo phase only exists if the adatom's energy level is beyond a critical value. The conductance is similar to the LDOS, thus, the Kondo peak in the LDOS can be observed with the scanning tunneling spectroscopy. In addition, in the presence of a direct coupling between the STM tip and the graphene, the conductance may be dramatically enhanced, depending on the coupling site.

title: Understanding Local Perceptions and the Role of Historical Context in Ecotourism Development: A Case Study of St. Kitts
Creators: name: Greening, Amber
Publisher: name: Utah State University
Year: 2014

description: Ecotourism is a popular tool for biodiversity conservation and local community development. It has long been argued that the depth of community involvement and support is imperative in creating effective and sustainable ecotourism programs, although widespread community involvement is rarely achieved in practice. Local perceptions of the benefits and impacts of ecotourism development and held values for the resources utilized in ecotourism activities may influence community support and decisions to be involved; however, little is understood as to why such perceptions exist. This research highlights community perceptions of ecotourism and held values for sea turtles and explains the emergence of these perceptions within two villages on the Caribbean island of St. Kitts. Data were collected through face-to-face community surveys, key-informant interviews, and participant observation during the summer of 2012. The field data revealed that community members did not perceive ecotourism to be widely beneficial, but instead viewed the government, people who work in the tourism industry, and tourists themselves to benefit from ecotourism practices. Further, community members perceived ecotourism as negatively affecting poor people, people who do not work in the tourism industry, and the environment. These perceptions of who or what is affected by ecotourism development were traced back through centuries of political-ecological processes on St. Kitts that have mediated local people’s relationship with their land and resources, as well as their relationships with each other. The results of this research suggest a focus on the role of ecotourism in amending the persistent marginalization of local people from their resources by applying a participatory development approach to ecotourism development through collaboration with existing community groups and social networks.

description: A two-component Bose-Einstein condensate confined in an axially-symmetric potential with two local minima, resembling two concentric annular traps, is investigated. The system shows a number of quantum phase transitions that result from the competition between phase coexistence, and radial/azimuthal phase separation. The ground-state phase diagram, as well as the rotational properties, including the (meta)stability of currents in this system, are analysed.

In particular, we use their proposal to determine the effect of finite temperature, as well as background electric and magnetic fields, on the chiral symmetry breaking order parameter. We also generalize their prescription to more complicated worldsheets and identify the operators dual to such worldsheets.

title: Characteristics and Genesis of Some Soils of the Upper Terraces of Lake Bonneville

Publisher: name: Utah State University
Year: 1980

description: The genesis and characteristics of the Timpanogos, Hillfield, and Sterling soils and an unnamed Mollisol (soil formed on north- slope) on the east part of Cache Valley were studied in order to determine (1) why the soil morphology is not chronologically related to the geomorphic surface and (2} why different soils have developed on these surfaces , even though the soil forming factors appear similar.
The particle size distribution of the upper horizons of the Timpanogos, Hillfield , and unnamed Mollisol pedons are relatively similar . These soils developed from stratified deposits with granulimetric composition in which 75 to 90 percent of the grains are less than 100 micrometers in diameter , characteristic of wind-blown material. Development of an incipient argillic horizon in Timpanogos pedon indicates this soil did not develop under the moist conditions of the Pleistocene and the geomorphic surface was not stable after deposition. The material was reworked by the wind. The Sterling soil formed on an alluvial fan which was deposited during Holocene time and its development is chronologically related to geomorphic surface.
The development of an incipient argillic horizon in the Timpanogos soil and a weak cambic horizon in the Hillfield soil and the unnamed Mollisol is due to topographic condition of the landscapes.
The thick and dark mollie epipedon in the unnamed Mollisol (north-slope) compared to the Hillfield soil (south- s lope) which has an epipedon with color light to be mollie and a less thick A horizon is related to effect of microclimate.

description: We describe an F-statistic search for continuous gravitational waves from galactic white-dwarf binaries in simulated LISA Data. Our search method employs a hierarchical template-grid based exploration of the parameter space. In the first stage, candidate sources are identified in searches using different simulated laser signal combinations (known as TDI variables). Since each source generates a primary maximum near its true "Doppler parameters" (intrinsic frequency and sky position) as well as numerous secondary maxima of the F-statistic in Doppler parameter space, a search for multiple sources needs to distinguish between true signals and secondary maxima associated with other, "louder" signals. Our method does this by applying a coincidence test to reject candidates which are not found at nearby parameter space positions in searches using each of the three TDI variables. For signals surviving the coincidence test, we perform a fully coherent search over a refined parameter grid to provide an accurate parameter estimation for the final candidates. Suitably tuned, the pipeline is able to extract 1989 true signals with only 5 false alarms. The use of the rigid adiabatic approximation allows recovery of signal parameters with errors comparable to statistical expectations, although there is still some systematic excess with respect to statistical errors expected from Gaussian noise. An experimental iterative pipeline with seven rounds of signal subtraction and re-analysis of the residuals allows us to increase the number of signals recovered to a total of 3419 with 29 false alarms.

description: We present an approach that allows for the preparation of well-defined large arrays of graphene wrinkles with predictable geometry. Chemical vapor deposition grown graphene transferred onto hexagonal pillar arrays of SiO2 with sufficiently small interpillar distance forms a complex network of two main types of wrinkle arrangements. The first type is composed of arrays of aligned equidistantly separated parallel wrinkles propagating over large distances, and originates from line interfaces in the graphene, such as thin, long wrinkles and graphene grain boundaries. The second type of wrinkle arrangement is composed of non-aligned short wrinkles, formed in areas without line interfaces. Besides the presented hybrid graphene topography with distinct wrinkle geometries induced by the pre-patterned substrate, the graphene layers are suspended and self-supporting, exhibiting large surface area and negligible doping effects from the substrate. All these properties make this wrinkled graphene a promising candidate for a material with enhanced chemical reactivity useful in nanoelectronic applications.
title: Schools That Serve Military Children: A Comparison of the Standardized Test Scores in the DoDEA School System Versus the Civilian School System
Creators: name: Fugate, Mary Eleanor
Publisher: name: Utah State University
Year: 2014

description: There are an estimated 1.2 million children with one or both parents enlisted in military service. These children are more geographically mobile than civilian children on average, and previous research suggests that mobility can have great effects on an individual's academic performance. This study seeks to answer the question: How does the standardized test performance of Department of Defense Education Activity (DoDEA) schools compare to those of public schools with high concentrations of military children (funded by Impact Aid). It is hypothesized that due to higher average levels of funding, a standard curriculum, and both embedded and intentional social support, DoDEA schools will have higher standardized test scores than public schools with high concentrations of military children. Consistent with previous literature that finds a standardized test bias in favor of white students, it is also hypothesized that schools that are located in ZIP Codes with high percentages of Black and Hispanic residents will have lower test scores. This research will contribute to a growing body of literature on childhood migration, as well as the literature focused on the effects of the military on personnel's families and children.
Through a series of bivariate correlations and nested regression analyses, I find that Impact Aid schools had higher percentages of students proficient in reading, math, and science than DoDEA schools. ZIP Code Tabulation Area measures of racial and ethnic composition, as reported in the American Community Survey 5-Year Estimates (2007- 2011), were statistically significant predictors of proficiency in reading and math. As the percentage of non-White community composition increased, the percentage of students proficient in reading and math decreased (β = -11.328*, p ≤ .05). Controlling for these community-level variables still resulted in higher overall standardized test proficiency in Impact Aid schools

description: Small amplitude oscillations are a commonly observed feature in prominences/filaments. These oscillations appear to be of local nature, are associated to the fine structure of prominence plasmas, and simultaneous flows and counterflows are also present. The existing observational evidence reveals that small amplitude oscillations, after excited, are damped in short spatial and temporal scales by some as yet not well determined physical mechanism(s). Commonly, these oscillations have been interpreted in terms of linear magnetohydrodynamic (MHD) waves, and this paper reviews the theoretical damping mechanisms that have been recently put forward in order to explain the observed attenuation scales. These mechanisms include thermal effects, through non-adiabatic processes, mass flows, resonant damping in non-uniform media, and partial ionization effects. The relevance of each mechanism is assessed by comparing the spatial and time scales produced by each of them with those obtained from observations. Also, the application of the latest theoretical results to perform prominence seismology is discussed, aiming to determine physical parameters in prominence plasmas that are difficult to measure by direct means.

title: Habitat Manipulation for the Reestablishment of the Utah Prairie Dog in Capitol Reef National Park
Creators: name: Player, Rodney L.
Publisher: name: Utah State University
Year: 1980

description: Utah prairie dogs were transplanted onto the site of a former colony located on Jones Bench in the northwestern corner of Capitol Reef National Park. Shrubs on Jones Bench were significantly taller than those found on active colonies of Ut ah prairie dogs located nearby on the Awapa Plateau. Therefore, the Jones Bench site offered an opportunity to test the hypothesis that shrub height is a major inhibitory factor on occupation of sites by prairie dogs. Four sites of 5 ha each were delimited on Jones Bench prior to the transplanting o~ animals. Vegetation treatments were carried out on three of the sites and the fourth was used as a nonmanipulated control . Mechanical treatments by rotobeating and railing were accomplished in late August, 1978. A herbicidal treatment (2,4-D) was done on the third site in the spring of 1979. Shrub height and percent cover were significantly reduced on all three treatment sites.
Post-treatment effects on the vegetation during the first year showed that the greatest percent moisture in herbage was found on the railed site, followed by the herbicide, rotobeaten, and control sites. Herbage production was approximately three times greater on the rotobeaten and railed sites than on the control and herbicide sites. Measurements of the visual obstructions of prairie dogs showed that the rotobeaten site had the greatest visibility followed by the railed, herbicide, and control sites.
Prior to release of prairie dogs on the study area, 200 artificial burrows arranged in a matrix, were dug with an enginepowered post-hole auger on each site. In late June and early July, 1979, 200 Utah prairie dogs were live-trapped near Loa, Utah. A total of 50 immature males, immature females, mature males, and mature females were released on each site. The animal's fur was dyed with a specific mark representing their respective transplant site before their release. The transplanted animals were monitored daily for 23 consecutive days following the release of the first animals and biweekly thereafter throughout the summer and early fall. Significant differences were found in the number of animals reestablished on each site except between the herbicide treatment and control site. The majority of all animals transplanted moved onto the rotobeaten site; the railed, herbicide, and control sites were selected in decreasing order. Results indicated that when transplanting animals onto sites of former colonies, particularly sites that are overgrown with shrubs, the chances of a successful transplant could be increased by first reducing shrub height and density. Proof of reestablishment at the Jones Bench site will be evident if reproduction is observed in the spring of 1980.

description: The heat generation by an electric current flowing through a quantum dot with the dot containing both electron-electron interaction and electron-phonon interaction, is studied. Using the non-equilibrium Keldysh Green's function method, the current-induced heat generation is obtained. We find that for a small phonon frequency, heat generation is proportional to the current. However, for a large phonon frequency, heat generation is in general qualitatively different from the current. It is non-monotonic with current and many unique and interesting behaviors emerge. The heat generation could be very large in the Coulomb blockade region, in which the current is very small due to the Coulomb blockade effect. On the other hand, in the resonant tunneling region, the heat generation is very small despite a large current, an ideal condition for device operation. In the curve of heat generation versus the bias, a negative differential of the heat generation is exhibited, although the current is always monotonously increasing with the bias voltage.

description: A new numerical framework, based on the use of a simple first order strongly hyperbolic evolution equations, is introduced and tested in case of 4-dimensional spherically symmetric gravitating systems. The analytic setup is chosen such that our numerical method is capable to follow the time evolution even after the appearance of trapped surfaces, more importantly, until the true physical singularities are reached. Using this framework, the gravitational collapse of various gravity-matter systems are investigated, with distinguished attention to the evolution in trapped regions. It is justified that in advance to the formation of these curvature singularities, trapped regions develop in all cases, thereby supporting the validity of the weak cosmic censor hypothesis of Penrose. Various upper bounds on the rate of blow-up of the Ricci and Kretschmann scalars and the Misner-Sharp mass are provided. In spite of the unboundedness of the Ricci scalar, the Einstein-Hilbert action was found to remain finite in all the investigated cases. In addition, important conceptual issues related to the phenomenon of topology changes are also discussed.

description: A system of symmetrically coupled identical oscillators with phase lag is presented, which is capable of generating a large repertoire of transient (metastable) "chimera" states in which synchronisation and desynchronisation co-exist. The oscillators are organised into communities, such that each oscillator is connected to all its peers in the same community and to a subset of the oscillators in other communities. Measures are introduced for quantifying metastability, the prevalence of chimera states, and the variety of such states a system generates. By simulation, it is shown that each of these measures is maximised when the phase lag of the model is close, but not equal, to pi/2. The relevance of the model to a number of fields is briefly discussed, with particular emphasis on brain dynamics.

description: We outline a novel linear instability that may arise in the dead-zones of protostellar disks, and possibly the fluid interiors of planets and protoplanets. In essence it is an axisymmetric buoyancy instability, but one that would not be present in a purely hydrodynamical gas. The necessary ingredients for growth include a negative radial entropy gradient (of any magnitude), weak magnetic fields, and efficient resistive diffusion (in comparison with thermal diffusion). The character of the instability is local, axisymmetric, and double-diffusive, and it attacks lengths much shorter than the resistive scale. Like the axisymmetric convective instability, it draws its energy from the negative radial entropy gradient; but by utilising the diffusing magnetic field, it can negate the stabilising influence of rotation. Its nonlinear saturated state, while not transporting appreciable angular momentum, could drive radial and vertical mixing, which may influence the temperature structure of the disk, dust dynamics and, potentially, planet formation.

These new algorithms are further steps in the direction of automating computer-assisted proofs of semi-conjugacies from a map on a manifold to a subshift of finite type.

The detached Work Program of the Boys Club of Vancouver : an analysis of the detached work program, its initiation and progress from May 1964 - September 1967
Creators: name: Mclean, Alan

description: The purpose of the study was: 1) To describe the similarities and differences in aims of detached work approaches between Vancouver and other major North American centres. 2) To analyze the attempted fulfillment of the goals of the detached work program of the Boys Clubs of Vancouver. 3) To suggest the formulation of data gathering tools that would provide the Boys Clubs of Vancouver with more accurate and researchable information for future inquiries. Questionnaires were formulated for: 1) The organization administrators in the areas where detached work was initiated 2) The youths with whom the detached worker made contact. 3) Data was provided by the Boys Club describing the pre- and post-orientation program which they offered to their line detached workers. A third set of data regarding line worker perceptions of their training and role was obtained by us in February 1967 using the same tool as the. Boys Club for their documentation. We used the above data tools to attempt to determine the following: 1) The influence of the detached worker on delinquency rates, family situations educational factors, peer group and.authority relationships and leisure time activities. 2) The amount of neighbourhood organization involvement in the detached work program. 3) The workers perception of their role and any discrepancies from the prescribed role formulated by the sponsoring agency. Provisional findings are as follows: 1) More youths increased their delinquent activities than decreased their delin- quent activities while associating with the detached worker. 2) No work was done with the families of the involved teens. 3) Patterns of leisure-time activities were significantly influenced by the detached worker's presence. 4) The number of referrals that agencies stated they wanted from the detached work program was significantly higher (50% yes 25% no) than actually handled (6% yes 75% no). There was a similar trend in the number of referrals wanted and handled by the detached work program (36% wanted referrals 19% actual referrals). 5) 50% of the organizations contacted stated they could take a more active role in the detached work program largely in the area of use of facilities. 6) Observations and conclusions in the area of the workers' perception of his role (#3 page 2) were totally subjective and largely without statistical reliability.

description: As emerging responsive materials, ferrogels have become highly attractive for biomedical and technical applications in terms of soft actuation, tissue engineering or controlled drug release. In the present study, bioderived ferrogels were fabricated and successfully deformed within moderate, heterogeneous magnetic fields. Synthesis was realized by arresting iron oxide nanoparticles in porcine gelatin by introduction of covalent crosslinks via treatment with energetic electrons for mesh refinement. This approach also allows for tuning thermal and mechanical stability of the gelatin matrix. Operating the bioferrogel in compression, magnetic forces on the nanoparticles are counterbalanced by the stiffness of the hydrogel matrix that is governed by a shift in thermodynamic equilibrium of swelling, as derived in the framework of osmosis. As gelatin and iron oxide nanoparticles are established as biocompatible constituents, these findings promise potential for in vivo use as contactless mechanical transducers.

description: We prove the non-uniform hyperbolicity of the Kontsevich-Zorich cocycle for a measure supported on abelian differentials which come from non-orientable quadratic differentials through a standard orientating, double cover construction. The proof uses Forni's criterion for non-uniform hyperbolicity of the cocycle for SL(2,R)-invariant measures. We apply these results to the study of deviations in homology of typical leaves of the vertical and horizontal (non-orientable) foliations and deviations of ergodic averages.

description: We describe how generalized complex geometry, which interpolates between complex and symplectic geometry, is compatible with T-duality, a relation between quantum field theories discovered by physicists. T-duality relates topologically distinct torus bundles, and prescribes a method for transporting geometrical structures between them. We describe how this relation may be understood as a Courant algebroid isomorphism between the spaces in question. This then allows us to transport Dirac structures, generalized Riemannian metrics, generalized complex and generalized Kahler structures, extending the "Buscher rules" well-known to physicists. Finally, we re-interpret T-duality as a Courant reduction, and explain that T-duality between generalized complex manifolds may be viewed as a generalized complex submanifold (D-brane) of the product, in a way that establishes a direct analogy with the Fourier-Mukai transform.

title: Calculating Willingness-To-Pay As a Function of Biophysical Water Quality and Water Quality Perceptions
Creators: name: Silva, Carlos G.

description: When estimating economic value associated with changes in water quality, recreation demand models typically depend upon either (i) biophysical measures of water quality as collected by natural scientists or (ii) the perception of water quality by recreationists. Models based upon biophysical metrics (such as oxygen concentration, pollutant concentrations, Secchi depth measurements, etc.) operate on the assumption that people can perceive and respond to these metrics, or respond to factors that are, indeed, correlated with the biophysical measure. Economists have often estimated willingness-to-pay (WTP) measures associated with unit changes in biophysical measures without examining the degree to which the measures are truly correlated with perceptions. Recreation demand models that are based upon respondents’ perceptions of water quality necessarily assume that perceptions correlate well with the measures used by scientists to evaluate water quality. Again, WTP for unit changes in perceptions have been estimated without examining the relationship to the underlying biophysical measures. The relationship between biophysical metrics and perceptions is rarely addressed, yet it has profound implications for water quality management and policy. Consider a federal or state agency wishing to manage the quality of its waters in an economically efficient way. Through mandated water quality monitoring regulations, an agency may have many years of biophysical measurements, but these measures are in no way linked to people’s perceptions of water quality and, thus, to WTP.
Using biophysical measures of water quality and recreation use data recently collected in Utah, this study links technical measures of water quality at a water body to survey respondents’ perceptions of water quality at the same site. This approach is akin to estimating an ecological production function wherein biophysical measures are “inputs” to water quality perceptions (the output). Truncated Negative Binomial models of water-based recreation are used to estimate welfare effects of changes in water quality as measured through (i) unit changes in biophysical measures, (ii) unit changes in perceptions, and (iii) unit changes in biophysical as they change perceptions through the ecological production function.

description: We report the creation and characterization of a near quantum-degenerate gas of polar $^{40}$K-$^{87}$Rb molecules in their absolute rovibrational ground state. Starting from weakly bound heteronuclear KRb Feshbach molecules, we implement precise control of the molecular electronic, vibrational, and rotational degrees of freedom with phase-coherent laser fields. In particular, we coherently transfer these weakly bound molecules across a 125 THz frequency gap in a single step into the absolute rovibrational ground state of the electronic ground potential. Phase coherence between lasers involved in the transfer process is ensured by referencing the lasers to two single components of a phase-stabilized optical frequency comb. Using these methods, we prepare a dense gas of $4\cdot10^4$ polar molecules at a temperature below 400 nK. This fermionic molecular ensemble is close to quantum degeneracy and can be characterized by a degeneracy parameter of $T/T_F=3$. We have measured the molecular polarizability in an optical dipole trap where the trap lifetime gives clues to interesting ultracold chemical processes. Given the large measured dipole moment of the KRb molecules of 0.5 Debye, the study of quantum degenerate molecular gases interacting via strong dipolar interactions is now within experimental reach.
title: Exploring Visitor Attitudes Toward the Proposed Greater Canyonlands National Monument: A Survey in Utah's Indian Creek Corridor

description: In August of 2012, the Outdoor Industry Association (OIA) sent a letter to President Barack Obama asking him to designate the Greater Canyonlands National Monument (GCNM). The proposed 1.4 million acre national monument would surround the already present 337,570 acre Canyonlands National Park, and would include public lands/waterways from five Utah counties. The OIA’s goal for the GCNM is to preserve the landscape for quality outdoor recreation by decreasing the amount of off-highway vehicle use and to eliminate the possibility of oil/gas drilling and mining. Given the proposal highlights outdoor recreation use benefits as the main catalyst for justification of additional conservation/protection of lands surrounding Canyonlands National Park, this study surveyed recreationists in the Indian Creek Corridor—an area within the boundaries of the proposed GCNM—to explore their attitudes toward the GCNM and the management of the area. This study examined how environmental orientation, place dependence, place identity, residential proximity, and recreational activity type related to attitudes toward the GCNM. Environmental orientation and residential proximity were both good predictors of attitudes toward the GCNM and the management of the Greater Canyonlands area. More biocentric-oriented people, and people who lived farther away from the Greater Canyonlands area, were more likely to have favorable attitudes toward the GCNM and were more opposed to land uses such as mining and energy development. In addition, visitors were largely “unsure” if the GCNM should be designated. Visitors felt most strongly that if the GCNM is going to be designated, the process of designation, the land that would be included, and management of the GCNM should be agreed upon by stakeholders before the monument is designated. This suggests a quick designation via public proclamation under the Antiquities Act of 1906 could largely exacerbate the already present conflict over public land management in the region, which would create an even more difficult environment for federal land managers.
title: Linking Montane Soil Moisture Measurements to Evapotranspiration Using Inverse Numerical Modeling

description: The mountainous areas in the Intermountain West (IMW) of the North America are considered as the major water reservoir for the Western US. Summer evapotranspiration (ET) and soil moisture are key factors affecting the annual water yield in the montane region of the IMW. This research estimated ET of four common vegetation types (aspen, conifer, grass, and sage) and areal soil moisture in an advanced instrumentation site located at the T.W. Daniel Experimental Forest (TWDEF). Among instrumented forest research sites worldwide, TWDEF is one of a few with triplicate measures of meteorological parameters, radiation, and soil moisture within four common vegetation types in the IMW. This unique dataset enables study and understanding of the ecological and hydrological responses to climate change in Utah and the IMW region. In a second phase of this study, summer water uses from the four common vegetation types were simulated using a numerical simulation model, Hydrus-1D. The simulation was informed by soil moisture measurements at three depths (0.1 m, 0.25 m, and 0.5 m) and by ET measured from an eddy covariance tower. The results confirmed the value of numerical simulations as a viable alternate method to estimated ET where no direct ET measurements are available. It also provided comparison of water use by these vegetation species including both high and low water years. In the third phase of this study, a comparison was made between the intermediate-scale areal soil moisture measured by a Cosmic-ray neutron probe (CRNP) and the in situ TDT soil moisture network at the TWDEF site. Improved correlations were obtained, especially after shallow rainfall events, by including numerically simulated soil moisture above 0.1 m where no measurements were available. The original CRNP calibration exhibited a dry bias during spring/early summer, leading to the need for a site-specific enhanced calibration, which improved the accuracy of the CRNP soil moisture estimate at the TWDEF site.

title: A Study of The Secant Law for Sporadic E

Publisher: name: Utah State University

description: The secant law is the relationship between the frequencies of a vertically incident wave and an obliquely incident wave that are reflected from the same level (i.e., density) of a stratified ionosphere. This thesis investigates the validity of the secant law applied to sporadic E.
Sporadic E data from two backscatter sounders and one vertical incidence ionosonde located in Japan were studied to test the validity of the secant law. The B-scan photos of the backscatter sounders were searched for Es patches which were then compared with the sporadic E parameters defined for vertical incidence ionograms.
Finally, two theoretical density models of Es were analyzed to predict the type of returns expected from the signals of backscatter sounder and vertical incidence ionosonde. These models included the partial reflection and scattering mechanisms that might be appropriate for sporadic E.

description: Muscle homeostasis and regeneration are complex cellular processes orchestrated by muscle stem cells and their interaction with their stem cell microenvironment. The fate of a muscle stem cell is influenced by different conditions such as muscle injury, cold stress, or disease. During extensive muscle repair and in the context of muscular dystrophy, we identified the critical function of the Epidermal Growth Factor Receptor (EGFR) in establishing cell polarity and in turn the efficient formation of myogenic progeny able to repair muscle. Using a novel drug screen, we identified the p53 protein to regulate muscle stem cell fate decision to repress the formation of brown adipose tissue as a means to regulate whole-body metabolism. To increase the impact of our research we also optimized protocols evaluating mouse satellite cell transplantation to delineate stem cell hierarchy and developed a new paradigm to model human muscle stem cell fate to better translate our findings into the clinical arena. These findings reveal the tunable nature of stem cell fate decisions and highlight the development of research tools to accelerate the translation of research findings to improve human health.
