description: We demonstrate that perfect conversion between charged supercurrents in superconductors and neutral supercurrents in electron-hole pair condensates is possible via a new Andreev-like scattering mechanism. As a result, when two superconducting circuits are coupled through a bilayer exciton condensate, the superflow in both layers is drastically modified. Depending on the phase biases the supercurrents can be completely blocked or exhibit perfect drag.

Discovery of Secondary Metabolites from Phenotypic Screens

description: Historically, microbially derived secondary metabolites have been strong contributors to biomedical research and human disease treatment. In particular, actinomycetes have had substantial impact as prolific producers of secondary metabolites with therapeutic significance. Herein, we postulate that actinomycete derived secondary metabolites harbor unique biological activity and structural novelty. To assess this, a library of actinomycete derived secondary metabolite fractions were subjected to variety of phenotypic screens. In addition, the potential of new versus standard screens to discover new structures was explored. Standard NP approaches were employed to isolate and structurally characterize two structurally novel SM were discovered from a marine derived Streptomyces sp. The first metabolite, N-acetyl-MY336-a, exists as amide rotamers and heterocyclic conformers. The second metabolite, 8β,17-epoxy-7β-hydroxy-12E,14-labdadiene, belongs to a large, common SM class of compounds, the diterpenoids. Additionally, a novel screen identified a Streptomyces secondary metabolite that functions as a QS inhibitor in GAS. To the best of our knowledge, the SM is the first of its kind as an inhibitor of GAS Rgg-mediated signaling. Moreover, molecular biology-based approaches determined that its putative target was determined to be the oligopeptide permease Opp. These studies illustrate the chemical and biological potential of secondary metabolites that can be identified through varied screening approaches.

description: We report measurements of the spin susceptibility and the electron effective mass for two-dimensional electrons confined at the interfaces of MgxZn1-xO/ZnO single heterostructures (x = 0.05, 0.08, and 0.11), grown by molecular-beam epitaxy on (0001) ZnO substrates. By tuning the built-in polarization through control of the barrier composition, the electron density was systematically varied in the range of 5.6 x 10^11 to 1.6 x 10^12 cm^-2, corresponding to a range of 3.1 < rs < 5.2, where rs is the average electron spacing measured in units of the effective Bohr radius. We used the coincidence technique, where crossings of the spin-split Landau levels occur at critical tilt angles of magnetic field, to evaluate the spin susceptibility. In addition, we determined the effective mass from the temperature dependence of the Shubnikov-de Haas oscillations measured at the coincidence conditions. The susceptibility and the effective mass both gradually increase with decreasing electron density, reflecting the role of electron-electron interaction.

description: Composites based on the matrix polymer polypropylene (PP) filled with single‐walled carbon nanotubes (SWCNTs) and boron‐doped SWCNTs (B‐SWCNTs) were prepared by melt‐mixing to analyze the influence of boron doping of SWCNTs on the thermoelectric properties of these nanocomposites. It was found that besides a significantly higher Seebeck coefficient of B‐SWCNT films and powder packages, the values for B‐SWCNT incorporated in PP were higher than those for SWCNTs. Due to the higher electrical conductivity and the higher Seebeck coefficients of B‐SWCNTs, the power factor (PF) and the figure of merit (ZT) were also higher for the PP/B‐SWCNT composites. The highest value achieved in this study was a Seebeck coefficient of 59.7 μV/K for PP with 0.5 wt% B‐SWCNT compared to 47.9 μV/K for SWCNTs at the same filling level. The highest PF was 0.78 μW/(m∙K2) for PP with 7.5 wt% B‐SWCNT. SWCNT macro‐ and microdispersions were found to be similar in both composite types, as was the very low electrical percolation threshold between 0.075 and 0.1 wt% SWCNT. At loadings between 0.5 and 2.0 wt%, B‐SWCNT‐based composites have one order of magnitude higher electrical conductivity than those based on SWCNT. The crystallization behavior of PP is more strongly influenced by B‐SWCNTs since their composites have higher crystallization temperatures than composites with SWCNTs at a comparable degree of crystallinity. Boron doping of SWCNTs is therefore a suitable way to improve the electrical and thermoelectric properties of composites. © 2020 by the authors.

description: We shall present and analyze two examples of extended theories of gravitation in Palatini formalism with matter that couples to the connection. This will show that the class of Further Extended Theories of Gravitation introduced in ref. [1] does not trivially reduce to f(R) models. It will also produce an example of theory that on-shell endowes spacetime with a non-trivial Weyl geometry where the connection is not induced by the metric structure (though it is compatible with it in the sense of Ehlers-Pirani-Schild; see ref. [2]).

title: Interactions Between Populations of Intermediate Wheatgrass and Western Wheatgrass as Influenced by Short-Duration Grazing and Moisture Availability
Creators: name: Bartels, Gerrit B.
Publisher: name: Utah State University
Year: 1992

description: The effects of grazing and moisture availability on the competitive interactions of intermediate wheatgrass (Thinopyrum intermedium (Host) Barkw. & D.R. Dewey) and western wheatgrass (Pascopyrum smithii (Rhydb.) A. Love) were examined under a short-duration grazing system in central Utah. The fate of tiller cohorts was observed at approximately monthly intervals at the interface between patches of these two rhizomatous grasses and in monospecific stands. The effects of short-duration grazing, clipping of western wheatgrass following grazing to achieve levels of utilization equivalent to that of intermediate wheatgrass, irrigation, and removal of the competitor were assessed in terms of the recruitment, longevity, and mortality of ramets of both species. The effects of severance of clonal connections and defoliation on the performance of young shoots of both species were also studied.
The tiller dynamics of the two species differed greatly. Maximum life span of intermediate wheatgrass tillers was approximately 18 months, while that of western wheatgrass tillers exceeded the 3.5-year observation period. Tiller turnover was higher in intermediate wheatgrass than in western wheatgrass. Defoliation tended to increase the mortality risk of intermediate wheatgrass ramets but not that of western wheatgrass ramets. Supplemental water had the opposite effect. Irrigation increased the probability of ramet survival for intermediate wheatgrass during the growing season but led to higher winter mortality for western wheatgrass ramets.
During the four years of this study (1987-1990), western wheatgrass was the competitive dominant species. Recruitment of intermediate wheatgrass ramets at the interface was reduced compared to monospecific stands while that of western wheatgrass was enhanced. The mortality of intermediate wheatgrass tillers increased as a result of competition with western wheatgrass but only when plants were grazed. Competition had little effect on the mortality of western wheatgrass ramets. The competitive ability of intermediate wheatgrass versus western wheatgrass improved when both species were grazed heavily and when plants were irrigated.
title: Effects of Diflubenzuron When Fed to Adult Female Alfalfa Weevils

Publisher: name: Utah State University
Year: 1984

description: The purpose of this project was to evaluate diflubenzuron ovicidal effects on adult female alfalfa weevils Hypera postica in the laboratory. There was little relationship of weevil mortality to dosage or length of exposure of the adult to the chemical. An indirect result of diflubenzuron was an increase in muscardine fungus (Beauveria Sp.). Other effects of the chemical on the adults were yellow deposits and tissue extending from the tip of the abdomen.
The main effect of dilfubenzuron when fed to female alfalfa weevils was on the eggs. The effects were dosage related, especially on eggs viability. The viability was dropped from 99% in the control to 38.9% on the treated insects in ten days using the highest dosage. Another effect of diflubenzuron on alfalfa weevil eggs was on the shape of the eggs. The treated insects laid longer and lighter color eggs.

description: We extend the powerful Pullback-Pushout (PBPO) approach for graph rewriting with strong matching. Our approach, called PBPO+, allows more control over the embedding of the pattern in the host graph, which is important for a large class of rewrite systems. We argue that PBPO+ can be considered a unifying theory in the general setting of quasitoposes, by demonstrating that PBPO+ can define a strict superset of the rewrite relations definable by PBPO, AGREE and DPO. Additionally, we show that PBPO+ is well suited for rewriting labeled graphs and some classes of attributed graphs, by introducing a lattice structure on the label set and requiring graph morphisms to be order-preserving.

title: Gambel Oak for Spanish Goats: A Digestion-Balance Evaluation of Nutrient Availability
Creators: name: Dick, Brian L.
Publisher: name: Utah State University
Year: 1988

description: Fresh-harvested Gambel oak (Quercus gambelii) browse was mixed with chopped alfalfa hay to formulate six diets , varying in oak content at two phenological stages. Diets included juvenile oak (65 ,80,95%), mature oak (40,80%), and an alfalfa control. Diets we re evaluated for goats using a series of total-collection digestion balance trials. Dry matter intake was highest for animal s on mature oak diets, and lowest on diets containing a high percentage of juvenile oak, possibly due to differences in diet dry matter content . Apparent digestibility of dry matter and cell wall components was lowest for mature oak diets, and highest for diets high in juvenile oak. Nitrogen and energy balances were positive in all cases , and all diets provided nitrogen and energy in excess of maintenance requirements. This was reflected by weight gains for all animals in every trial. Fecal and urinary nitrogen losses did not appear to be related to tannin content of the diets, because high-percentage juvenile oak diets resulted in reduced nitrogen outputs, presumably due to reduced nitrogen intakes for these diets. In comparison with previous data using pelleted formulations, the fresh-fed material was consistently higher in digestibility of the various fractions, and associated with lower dry matter intakes.
The kinematics of NGC1333-IRAS2A - a true Class 0 protostar

description: Low-mass star formation is described by gravitational collapse of dense cores of gas and dust. At some point during the collapse, a disk is formed around the protostar and the disk will spin up and grow in size as the core contracts because of angular momentum conservation. The question is how early the disk formation process occurs. In this paper we aim to characterize the kinematical state of a deeply embedded, Class 0 young stellar object, NGC1333-IRAS2A, based on high angular resolution (< 1$''$ $\approx$ 200 AU) interferometric observations of HCN and H$^{13}$CN J = 4-3 from the Submillimeter Array, and test whether a circumstellar disk can be detected based on gas kinematic features. We adopt a physical model which has been shown to describe the object well and obtain a fit of a parameterized model of the velocity field, using a two-dimensional axis-symmetric radiation transfer code. The parameterization and fit to the high angular resolution data characterize the central dynamical mass and the ratio of infall velocity to rotation velocity. We find a large amount of infall and very little rotation on all scales. The central object has a relatively low mass of 0.25 M$_\odot$ . As an object with a low stellar mass compared to the envelope mass, we conclude that NGC1333-IRAS2A is consistent with the suggestion that, as a Class 0 object, it represents the earliest stages of star formation. The large amount of infall relative to rotation also suggests that this is a young object. We do however find the need of a central compact component on scales of a few hundred AU based on the continuum data, which suggests that disk formation happens shortly after the initial gravitational collapse. The data do not reveal a distinct velocity field for this 0.1 M$_\odot$ component.

description: In network meta-analysis (NMA), we synthesize all relevant evidence about health outcomes with competing treatments. The evidence may come from randomized controlled trials (RCT) or non-randomized studies (NRS) as individual participant data (IPD) or as aggregate data (AD). We present a suite of Bayesian NMA and network meta-regression (NMR) models allowing for cross-design and cross-format synthesis. The models integrate a three-level hierarchical model for synthesizing IPD and AD into four approaches. The four approaches account for differences in the design and risk of bias in the RCT and NRS evidence. These four approaches variously ignoring differences in risk of bias, using NRS to construct penalized treatment effect priors and bias-adjustment models that control the contribution of information from high risk of bias studies in two different ways. We illustrate the methods in a network of three pharmacological interventions and placebo for patients with relapsing-remitting multiple sclerosis. The estimated relative treatment effects do not change much when we accounted for differences in design and risk of bias. Conducting network meta-regression showed that intervention efficacy decreases with increasing participant age. We re-analysed a network of 431 RCT comparing 21 antidepressants, and we did not observe material changes in intervention efficacy when adjusting for studies high risk of bias. In summary, the described suite of NMA/NMR models enables inclusion of all relevant evidence while incorporating information on the within-study bias in both observational and experimental data and enabling estimation of individualized treatment effects through the inclusion of participant characteristics.

description: We report a model that makes it possible to analyze quantitatively the dipole blockade effect on the dynamical evolution of a two two-level atom system driven by an external laser field. The multiple excitations of the atomic sample are taken into account. We find very large concurrence in the dipole blockade regime. We further find that entanglement can be tuned by changing the intensity of the exciting laser. We also report a way to lift the dipole blockade paving the way to manipulate in a controllable way the blockade effects. We finally report how a continuous monitoring of the dipole blockade would be possible using photon-photon correlations of the scattered light in a regime where the spontaneous emission would dominate dissipation in the sample.

As a result, we find that the state after a measurement depends on the number of particles.

title: An Assessment of Thematic Mapper Satellite Data For Classifying Conifer Types in Northern Utah
Creators: name: Mazurski, Madeline R.
Publisher: name: Utah State University
Year: 1989

description: Land-cover identification and mapping are an integral part of natural resource planning and management. Satellite imagery provides a way to obtain land cover information, particularly for large tracts of land such as those administered by federal and state agencies.
This study assesses the usefulness of the Brightness/Greenness Transformation of Landsat Thematic Mapper data for differentiating conifer forest types in northern Utah. Satellite data for the Logan Ranger District of the Wasatch-Cache National Forest were classified into 27 vegetation classes. Of these, nine were determined to be conifer classes and were used in subsequent analyses. Ten sites of each conifer class type were field checked and vegetation and physical site characteristics recorded.
The Brightness/Greenness Transformation was able to distinguish conifer areas from other vegetation types. High-density conifer classes were classified at 94 percent accuracy. Low-density conifer classes were classified correctly 65 percent of the time. The Brightness/Greenness Transformation alone met with limited success in distinguish ing between conifer species. Each class showed great variability with respect to major overstory species. Analysis of variance indicated that none of the site factors measured consistently corresponded with the spectrally designated classes. While several factors differed significantly among classes, no factor was significantly different for all c l ass-pair combinations.
Correlation analysis revealed that brightness, greenness, and wetness values related more to environmental values than to conifer species. Brightness was highly correlated with percent of exposed soil on the site. Greenness was highly correlated to the presence of deciduous and herbaceous vegetation. Wetness was highly correlated to total tree and conifer cover values.
Adding slope and aspect data to the Brightness/Greenness Transformation classes with the highest percentages of canopy cover did allow separation of lodgepole pine and Douglas fir. High percentagecanopy cover sites on slopes less than 35 percent were classified as lodgepole pine with 89 percent accuracy. On slopes greater than or equal to 35 percent, Douglas fir was found with 79 percent accuracy.

description: Liquid water at ambient temperature displays ultrafast molecular motions and concomitant fluctuations of very strong electric fields originating from the dipolar H2O molecules. We show that such random intermolecular fields induce the tunnel ionization of water molecules, which becomes irreversible if an external terahertz (THz) pulse imposes an additional directed electric field on the liquid. Time-resolved nonlinear THz spectroscopy maps charge separation, transport, and localization of the released electrons on a few-picosecond time scale. The highly polarizable localized electrons modify the THz absorption spectrum and refractive index of water, a manifestation of a highly nonlinear response. Our results demonstrate how the interplay of local electric field fluctuations and external electric fields allows for steering charge dynamics and dielectric properties in aqueous systems.

description: We consider the gluon propagator $D(p^2)$ at various lattice sizes and spacings in the case of pure SU(3) Yang-Mills gauge theories using the Landau gauge fixing. We discuss a class of fits in the infrared region in order to (in)validate the tree level analytical prediction in terms of the (Refined) Gribov-Zwanziger framework. It turns out that an important role is played by the presence of the widely studied dimension two gluon condensate $\braket{A^2}$. Including this effect allows to obtain an acceptable fit up to 1 á 1.5 GeV, while corroborating the Refined Gribov-Zwanziger prediction for the gluon propagator. We also discuss the infinite volume extrapolation, leading to the estimate $D(0)=8.3\pm0.5\text{GeV}^{-2}$. As a byproduct, we can also provide the prediction $\braket{g^2 A^2}\approx 3\text{GeV}^2$ obtained at the renormalization scale $μ=10\text{GeV}$.

description: We study the flavor structure of the lepton and baryon number--conserving dimension-6 operators in the Standard Model effective field theory (SMEFT). Building on the work of [1], we define several well-motivated flavor symmetries and symmetry-breaking patterns that serve as competing hypotheses about the ultraviolet (UV) dynamics beyond the SM, not far above the TeV scale. In particular, we consider four different structures in the quark sector and seven in the charged lepton sector. The set of flavor-breaking spurions is (almost) always taken to be the minimal one needed to reproduce the observed charged fermion masses and mixings. For each case, we explicitly construct and count the operators to the first few orders in the spurion expansion, providing ready-for-use setups for phenomenological studies and global fits. We provide a Mathematica package SMEFTflavor to facilitate similar analyses for flavor symmetries not covered in this work.

description: Plasmon-driven sequential chemical reactions were successfully realized in an aqueous environment. In an electrochemical environment, sequential chemical reactions were driven by an applied potential and laser irradiation. Furthermore, the rate of the chemical reaction was controlled via pH, which provides indirect evidence that the hot electrons generated from plasmon decay play an important role in plasmon-driven chemical reactions. In acidic conditions, the hot electrons were captured by the abundant H + in the aqueous environment, which prevented the chemical reaction. The developed plasmon-driven chemical reactions in an aqueous environment will significantly expand the applications of plasmon chemistry and may provide a promising avenue for green chemistry using plasmon catalysis in aqueous environments under irradiation by sunlight.

description: In a recent paper (Vigoureux et al. Int. J. Theor. Phys. 47:928, 2007) it has been suggested that the velocity of light and the expansion of the universe are two aspects of one single concept connecting space and time in the expanding universe. It has then be shown that solving Friedmann's equations with that interpretation (and keeping c = constant) can explain number of unnatural features of the standard cosmology (for example: the flatness problem, the problem of the observed uniformity in term of temperature and density of the cosmological background radiation, the small-scale inhomogeneity problem...) and leads to reconsider the Hubble diagram of distance moduli and redshifts as obtained from recent observations of type Ia supernovae without having to need an accelerating universe. In the present work we examine the problem of the cosmological constant. We show that our model can exactly generate $Λ$ (equation of state $P_φ= - ρ_φc^2$ with $Λ\propto R^{-2}$) contrarily to the standard model which cannot generate it exactly. We also show how it can solve the so-called cosmic coincidence problem.

description: The many similarities between the prompt emission pulses in gamma ray bursts (GRBs) and X-ray flares during the fast decay and afterglow phases of GRBs suggest a common origin. In the cannonball (CB) model of GRBs, this common origin is mass accretion episodes of fall-back matter on a newly born compact object. The prompt emission pulses are produced by a bipolar jet of highly relativistic plasmoids (CBs) ejected in the early, major episodes of mass accretion. As the accretion material is consumed, one may expect the engine's activity to weaken. X-ray flares ending the prompt emission and during the afterglow phase are produced in such delayed episodes of mass accretion. The common engine, environment and radiation mechanisms (inverse Compton scattering and synchrotron radiation) produce their observed similarities. Flares in both long GRBs and short hard gamma ray bursts (SHBs) can also be produced by bipolar ejections of CBs following a phase transition in compact objects due to loss of angular momentum and/or cooling. Optical flares, however, are mostly produced in collisions of CBs with massive stellar winds/ejecta or with density bumps along their path. In this paper we show that the master formulae of the CB model of GRBs and SHBs, which reproduce very well their prompt emission pulses and their smooth afterglows, seem to reproduce also very well the lightcurves and spectral evolution of the prominent X-ray and optical flares that are well sampled.

description: Wheat (Triticum aestivum L.) zygotic embryogenesis occurs in a dynamically regulated ovular environment, and in ovulo hormones regulate embryogenic processes. Levels of ABA, IAA, and the cytokinins Z, ZR, DHZ, DHZR, iP, and iPA were studied in developing wheat kernels from anthesis to maturity. High cytokinin and low IAA and ABA levels were associated with the early stage of embryo formation and active tissue histodifferentiation. Following histodifferentiation, cytokinin levels declined while IAA accumulated throughout the stage of active grain growth and then declined with grain maturity. ABA levels increased at the soft-dough developmental stage and through to grain maturity. Endogenous +ABA levels in developing wheat grains treated with fluridone, which indirectly blocks ABA synthesis, declined at the soft-dough stage. As a result, mature desiccated fluridone-treated kernels exhibited little dormancy. However, fluridone-treated kernels were not viviparous, suggesting a strong caryopsis-embryo interaction in maintaining embryogenically competent tissues. Induction of embryogenically competent wheat callus cultures was highly variable between genotypes and pre-initiation environments. Genotypic and environmental influences altered endogenous hormone levels and affected embryogenic competence. Establishment of competent embryo explants for somatic embryo induction was favored by a high cytokinin-to-auxin ratio and very low ABA levels throughout histodifferentiation (around 4 to 8 DPA). Similar to embryos forming within the caryopses, competent callus cultures had a high cytokinin (Z)-to-auxin ratio at 7 DPI. Increased frequency of embryogenic cultures was achieved when embryo explants were excised during a narrow window of low hormone levels. Wheat line and pre-initiation environment affected this window. Simulation in vitro of the in ovulo wheat kernel environment improved zygotic embryogenesis in vitro . Embryos exposed to physiologically normal ABA levels and low 0 2 tensions of 2.5 mM (7%) most closely approached morphological and physiological normalcy. The culmination of these studies clearly defines windows of embryo development for explant excision, associated roles of plant hormones in embryogenesis, and in ovulo hormone levels that vastly improve the frequency of successful embryogenesis when simulated in in vitro culture systems.

description: We study the process γγ->h->bb_bar at ILC as a probe of different little Higgs models, including the simplest little Higgs model (SLH), the littlest Higgs model (LH), and two types of littlest Higgs models with T-parity (LHT-I, LHT-II). Compared with the Standard Model (SM) prediction, the production rate is found to be sizably altered in these little Higgs models and, more interestingly, different models give different predictions. We find that the production rate can be possibly enhanced only in the LHT-II for some part of the parameter space, while in all other cases the rate is suppressed. The suppression can be 10% in the LH and as much as 60% in both the SLH and the LHT-I/LHT-II. The severe suppression in the SLH happens for a large \tanβand a small m_h, in which the new decay mode h->ηη(ηis a light pseudo-scalar) is dominant; while for the LHT-I/LHT-II the large suppression occurs when f and m_h are both small so that the new decay mode h->A_H A_H is dominant. Therefore, the precision measurement of such a production process at the ILC will allow for a test of these models and even distinguish between different scenarios.

description: We exploit a new theory of gravity proposed by Finzi, which gives stronger interaction at large scales, to study the thermodynamic description of galaxy clusters. We employ a statistical model to deduce various thermodynamics equations of state. In addition, we analyze the behavior of clustering parameter in comparison to its standard (Newtonian) counterpart. The general distribution function and its behavior with varying strength of clustering parameter are also studied. The possibility of phase transition is investigated and it is observed that a phase transition is possible though hierarchically. We also analyze the model by comparing the results with data available through SDSS-III, and obtain the parameters involved.

title: Analysis of Gender and Success-Related Kinematic Differences of Elite Sport Rock Climbers During Competition
Creators: name: Slaugh, Russell
Publisher: name: Utah State University
Year: 1998

description: This study compared differences in kinematically based performance success characteristics of elite sport rock climbers during competition both within and across the variable of gender. The purpose of this study was to identify kinematically based performance success and gender differences in elite sport rock climbers for the development of further studies and gender-specific training procedures. The dependent variables included the kinematics of the dynamic grasping hand (DGH) and the center of mass (CM) and the timing of these variables.
The participants included both the men and women competitors registered for the 1997 American Sport Climbing Federation's Fall National competition held at the Boulder Rock Club in Boulder, Colorado. Analysis was performed on the top five placing participants in each respective gender category (N = I 0). For comparison within gender, the first through third place finishers were classified as the top performers with a higher degree of performance success than the bottom performers who placed fourth and fifth (n = 5).
Adjusted R-squared values were computed by way of multiple regression for the kinematic variables; variables providing adjusted R-squared coefficients greater than .24 were selected for further analysis. A one-way repeated measures ANOV A was computed for the selected kinematic variables and finish place of the participants. Standardized mean difference effect sizes were computed to determine practical significance.
No statistical significance was found at or below the .05level of probability for finish place and any of the kinematic variables. Effect size differences were found for the DGH and CM kinematics with the top-performing men and women exhibiting more controlled horizontal movements, and more powerful but still controlled vertical movement. The control of the vertical CM motion indicated by the tops was evident from lesser distances the CM traveled. The kinematics of the CM show the top men and women with less vertical distances traveled, indicating a more efficient movement. Gender differences included the males performing the route segment with slower times but with faster DGH events. The top men provided greater event vertical velocities while the women provided greater horizontal velocities and accelerations. These differences provide considerations for the development of specific training protocols to address performance success based requirements that are gender-specific.
title: A Study of a Possible Predictor of Pilot-Error Aircraft Accidents in the State of Utah
Creators: name: Huntington, Garn O.
Publisher: name: Utah State University
Year: 1977

description: It was the objective of this study to determine to what extent automobile driving records may be used in predicting the occurrance of pilot-error aircraft accidents.
An analysis was conducted on all pilot-error aircraft accidents in the state of Utah during the time period of January 1, 1972 through December 31, 1973.
Although the total calculations were not significant, the evidence indicates that the pilot who receives many automobile driving citations will be involved in more pilot-error aircraft accidents. A trend was established with age and the Weighted Citation Index, with 70.69 percent of the grouped classes correctly classified.

description: We study homeomorphisms of the two-torus, homotopic to the identity, whose rotation set has non-empty interior. For such maps, we give a purely topological characterisation of elliptic islands in a chaotic sea in terms of local rotation subsets. We further show that the chaotic regime defined in this way cannot contain any Lyapunov stable points. In order to demonstrate our results, we introduce a parameter family inspired by an example of Misiurewicz and Ziemian.

description: Small-angle X-ray scattering from GaN nanowires grown on Si(111) is measured in the grazing-incidence geometry and modelled by means of a Monte Carlo simulation that takes into account the orientational distribution of the faceted nanowires and the roughness of their side facets. It is found that the scattering intensity at large wavevectors does not follow Porod's law I(q) ∝ q-4. The intensity depends on the orientation of the side facets with respect to the incident X-ray beam. It is maximum when the scattering vector is directed along a facet normal, reminiscent of surface truncation rod scattering. At large wavevectors q, the scattering intensity is reduced by surface roughness. A root-mean-square roughness of 0.9 nm, which is the height of just 3-4 atomic steps per micrometre-long facet, already gives rise to a strong intensity reduction. open access.
title: Plant Monoterpenoids as Factors in Diet Selection and Grazing Behaviour of Sheep
Creators: name: Yabann, Wilson Kimuti A.
Publisher: name: Utah State University
Year: 1984

description: Grazing trials were conducted in west-central Utah in August and November, 1983. Sheep were stocked in 0.06 hectare paddocks containing a homogeneous stand of the shrub big sagebrush (Artemisia tridentata subsp. tridentata). Stocking rate was 1344 animal-unit-days per hectare. Close observation was made of plants and plant parts of the sagebrush that the sheep consumed or refused to consume. Similar samples were hand-harvested from browsed and rejected plants and plant parts. These samples were later analyzed in the laboratory for monoterpenoid content, crude protein levels and digestible organic matter.
There was large variability of monoterpenoid concentrations from plant to plant ranging from 0.06% to 0.63% dry matter basis among the browsed plants and from 0.30% to 1.80% among the rejected . Sheep consumed those plants and plant parts that were relatively lower in monoterpenoid content. They did not select for the proximate constituents (crude protein and digestible organic matter) of the whole
plant or plant parts. The rejected plants and plant parts were generally higher in bach monoterpenoids and proximate constituents than were the corresponding browsed plants and plant parts.
Seasonal effects were important on the composition of entire diets selected by the free grazing sheep. From observation, sheep consumed more sagebrush in autumn than they did in summer.
Samples collected from esophageally fistulated sheep showed crude protein content to be significantly (P = 0.05) higher in autumn than in summer. As sheep shifted their dietary selection from annual grasses to big sagebrush , generally upward trend in dietary crude protein was observed during both seasons . In vitro organic matter digestibilities (IVOMD) were generally low due to the nature of plant parts consumed by the sheep, i.e., they consumed growth from the previous year.
Feeding station intervals (FSI), the time spent per feeding station, were measured. A feeding station is the amount of forage available to a grazing animal when its forefeet are stationary. As sheep shifted their dietary selection to sagebrush, FSI increased significantly. Apparently shrubs offered relatively larger amounts of forage to select from than herbaceous vegetation calling for more time per feeding station.
