description: We report on the neutron response of the LAMBDA spectrometer developed earlier for high-energy gamma-ray measurement. The energy dependent neutron detection efficiency of the spectrometer has been measured using the time-of-flight (TOF) technique and compared with that of an organic liquid scintillator based neutron detector (BC501A). The extracted efficiencies have also been compared with those obtained from Monte Carlo GEANT4 simulation. We have also measured the average interaction length of neutrons in the BaF2 crystal in a separate experiment, in order to determine the TOF energy resolution. Finally, the LAMBDA spectrometer has been tested in an in-beam-experiment by measuring neutron energy spectra in the 4He + 93Nb reaction to extract nuclear level density parameters. Nuclear level density parameters obtained by the LAMBDA spectrometer were found to be consistent with those obtained by the BC501A neutron detector, indicating that the spectrometer can be efficiently used as a neutron detector to measure the nuclear level density parameter.

description: Ein Sondenfund aus der ostwestfälischen Wüstung Wietheim bei Bad Lippspringe (Kr. Paderborn) ist fälschlich als Pferdeschmuck mit Tierkopfenden skandinavischer Herkunft aus dem frühen 9. Jahrhundert interpretiert worden. Tatsächlich handelt es sich um die Parierstange eines spätmittelalterlichen Dolches der Zeit um 1400, wie ein weitgehend identisches Ver gleichs stück an einem intakten Dolch belegt.
description: A find revealed with the help of a metal detector in the deserted village Wietheim at Bad Lippspringe (Kr. Paderborn) in East Westphalia has been interpreted incorrectly as a horse ornament with animal head endings of Scandinavian origin of the early 9th century. It is in fact the guard of a late medieval dagger from the time around 1400 as is demonstrated by a largely identical parallel with a complete dagger.

description: Extensive Air Showers are complex macroscopic objects initiated by single ultra-high energy particles. They are the result of millions of high energy reactions in the atmosphere and can be described as the superposition of hadronic and electromagnetic cascades. The hadronic cascade is the air shower backbone, and it is mainly made of pions. Decays of neutral pions initiate electromagnetic cascades, while the decays of charged pions produce muons which leave the hadronic core and travel many kilometers almost unaffected. Muons are smoking guns of the hadronic cascade: the energy, transverse momentum, spatial distribution and depth of production are key to reconstruct the history of the air shower. In this work, we overview the phenomenology of muons on the air shower and its relation to the hadronic cascade. We briefly review the experimental efforts to analyze muons within air showers and discuss possible paths to use this information.

description: Recent data from the WMAP, ACT and SPT experiments provide precise measurements of the cosmic microwave background temperature power spectrum over a wide range of angular scales. The combination of these observations is well fit by the standard, spatially flat LCDM cosmological model, constraining six free parameters to within a few percent. The scalar spectral index, n_s = 0.9690 +/- 0.0089, is less than unity at the 3.6 sigma level, consistent with simple models of inflation. The damping tail of the power spectrum at high resolution, combined with the amplitude of gravitational lensing measured by ACT and SPT, constrains the effective number of relativistic species to be N_eff = 3.28 +/- 0.40, in agreement with the standard model's three species of light neutrinos.

description: Wie erfolgreich sich Kinder sprachlich entwickeln, hängt im Bereich der Frühpädagogik im Wesentlichen von der Sprachförderkompetenz der frühpädagogischen Fachkraft ab. Eine professionelle Sprachförderkompetenz zeichnet sich u. a. durch die Fähigkeit einer sprachanregenden Interaktionsgestaltung aus, die durch sogenannte Sprachfördertechniken beeinflusst wird. Diese gilt es in der Aus- und Weiterbildung zu schulen, wobei Kompetenzmodelle von einer Verbindung zwischen den Kompetenzfacetten des Wissens und des Handelns ausgehen. Im Bereich der Frühpädagogik fehlt es allerdings an domänenspezifischen Kompetenzuntersuchungen, die diese Verbindung für die sprachanregende Interaktionsgestaltung bestätigen. An dieser explorativ ausgerichteten Studie zur Untersuchung eines Zusammenhangs zwischen handlungsnahem sprachförderspezifischem Wissen und dem sprachförderlichen Handeln nahmen 47 frühpädagogische Fachkräfte aus der Schweiz und aus Deutschland teil. Das handlungsnahe Wissen wurde mittels eines Filmvignetteninterviews und das Handeln mittels einer Videobeobachtung erhoben. Die deskriptiven Ergebnisse zeigen, dass handlungsnahes Wissen basierend auf verschiedenen als sprachförderwirksam angesehenen Sprachförderdimensionen unterschiedlich differenziert erfasst werden konnte. Auch in der Häufigkeit der Anwendung von spezifischen Sprachfördertechniken im Handeln zeichnen sich grosse Unterschiede innerhalb der Stichprobe ab. Ein statistischer Zusammenhang konnte zwischen spezifischen, auf einer Mikroebene der Sprachförderung angesiedelten Wissensaspekten (Dialogvertiefung, Fragen und korrigierendes Verhalten) gefunden werden. Wissensbereiche, die auf einer übergeordneten Ebene der Sprachförderung anzusiedeln sind (Dialog- und Beziehungsgestaltung), stehen nicht mit dem Handeln in Verbindung. Die Ergebnisse werden in Bezug auf das methodische Vorgehen und die inhaltliche Strukturierung von sprachförderspezifischem handlungsnahem Wissen in eine Mikro- und in eine Makroebene kritisch diskutiert.

description: It has recently been shown that Skyrmions with a fixed size can exist in theories without a Skyrme term, providing the Skyrmion is located on a domain wall. Here we numerically compute domain wall Skyrmions of this type, in a (2+1)-dimensional O(3) sigma model with a potential term. Moreover, we investigate Skyrmion dynamics, to study both Skyrmion stability and the scattering of multi-Skyrmions. We demonstrate that scattering events in which both Skyrmions remain on the same domain wall are effectively one-dimensional, and at low speeds are well-approximated by kink scattering in the integrable sine-Gordon model. However, more exotic fully two-dimensional scatterings are also presented, in which Skyrmions that are initially on different domain walls emerge on the same domain wall.

description: A simple first moment argument shows that in a randomly chosen $k$-SAT formula with $m$ clauses over $n$ boolean variables, the fraction of satisfiable clauses is $1-2^{-k}+o(1)$ as $m/n\rightarrow\infty$ almost surely. In this paper, we deal with the corresponding algorithmic strong refutation problem: given a random $k$-SAT formula, can we find a certificate that the fraction of satisfiable clauses is $1-2^{-k}+o(1)$ in polynomial time? We present heuristics based on spectral techniques that in the case $k=3$ and $m\geq\ln(n)^6n^{3/2}$, and in the case $k=4$ and $m\geq Cn^2$, find such certificates almost surely. In addition, we present heuristics for bounding the independence number (resp. the chromatic number) of random $k$-uniform hypergraphs from above (resp. from below) for $k=3,4$.

description: Cyanoformaldehyde (HCOCN) molecule has recently been suspected towards the Sagittarius B2(N) by the Green Bank telescope, though a confirmation of this observation has not yet been made. In and around a star forming region, this molecule could be formed by the exothermic reaction between two abundant interstellar species, H2CO and CN. Till date, the reaction rate coefficient for the formation of this molecule is unknown. Educated guesses were used to explain the abundance of this molecule by chemical modeling. In this paper, we carried out quantum chemical calculations to find out empirical rate coefficients for the formation of HCOCN and different chemical properties during the formation of HCOCN molecules. Though HCOCN is stable against unimolecular decomposition, this gas phase molecule could be destroyed by many other means, like: ion-molecular reactions or by the effect of cosmic rays. Ion-molecular reaction rates are computed by using the capture theories. We have also included the obtained rate coefficients into our large gas-grain chemical network to study the chemical evolution of these species in various interstellar conditions. Formation of one of the isotopologue(DCOCN) of HCOCN is also studied. Our study predicts the possibility of finding HCOCN and DCOCN in the ice phase with a reasonably high abundance. In order to detect HCOCN or DCOCN in various interstellar environments, it is necessary to know the spectroscopic properties of these molecules. To this effect, we carried out quantum chemical calculations to find out different spectral parameters of HCOCN for the transition in electronic, infrared and rotational modes. We clearly show how the isotopic substitution (DCOCN) plays a part in the vibrational progressions of HCOCN.

Creators: name: Dunaway, Andrew E.
Publisher: name: University of Kentucky Libraries

description: Feed accounts for the highest cost associated in poultry production, with energy-containing feedstuffs being the most expensive portion of the cost of feeding. The increasing demand for poultry meat gives reason to determine accurate apparent metabolizable energy (AME) values for various feedstuff through measuring energy utilization in the birds. The adaptation length of birds fed an experimental diet may affect the determined AME value due to the diet matrix and physiochemical properties of the feedstuff. Therefore, the objective of this thesis was to evaluate a select group of energy-containing feedstuff with different diets and with factors such as coccidia challenge and exogenous enzyme supplementation that may influence the determined AME values in broiler chickens.

description: After introducing agile approach in 2001, several agile methods were founded over the last decade. Agile values such as customer collaboration, embracing changes, iteration and frequent delivery, continuous integration, etc. motivate all software stakeholders to use these methods in their projects. The main issue is that for using these methods instead of traditional methods in software development, companies should change their approach from traditional to agile. This change is a fundamental and critical mutation. Several studies have been done for investigating of barriers, challenges and issues in agile movement process and also in how to use agile methods in companies. The main issue is altering attitude from traditional to agile approach. We believe that before managing agile transformation process, its related factors should be studied in deep. This study focuses on different dimensions of changing approach to agile from change management perspective. These factors are how to being agile, method selection and awareness of challenges and issues. These fundamental factors encompass many items for agile movement and adoption process. However these factors may change in different organization, but they should be studied in deep before any action plan for designing a change strategy. The main contribution of this paper is introducing and these factors and discuss on them deeply.
Inhibition of post-harvest pathogen gray mold (Botrytis cinerea) on strawberry (Fragaria ananassa) with application of thyme (Thymus vulgaris) essential oil

description: Fruit and vegetable losses in the United States result in significant food waste and billions of dollars in lost revenue, with a major portion of these losses occurring between harvest and distribution. Postharvest losses due to improper handling, storage and disease are among the most prominent. Botrytis cinerea, commonly called grey mold, is a latent necrotrophic fungus responsible for disease observed in over 200 plant species and can infect many plant parts such as stems, leaves, and fruit. In strawberry fruit (Fragaria ananassa), B. cinerea is a major pathogen and has been shown to cause total crop loss and significantly reduce shelf-life for this fresh high value product. Due to the antimicrobial resistance of fungal isolates, including B. cinerea, many producers, distributors, and even consumers are looking towards integrated pest management (IPM) strategies to mitigate their losses and extend product shelf-life. In this dissertation, we use thyme essential oil, which has demonstrated significant antimicrobial activities, to address and mitigate these losses in postharvest application on strawberry caused by grey mold.

description: The adsorption of the chiral molecule lactic acid on chiral Pt surfaces is studied by Density Functional Theory calculations. First we study the adsorption of L-lactic acid on the flat Pt(111) surface. Using the oPBE-vdW functional which includes van der Waals forces on an ab initio level, it is shown that the molecule has two binding sites, a carboxyl and the hydroxyl oxygen atoms. Since real chiral surfaces are (i) known to undergo thermal roughening that alters the distribution of kinks and step edges but not the overall chirality and (ii) kink sites and edge sites are usually the energetically most favored adsorption sites, we focus on two surfaces that allow qualitative sampling of the most probable adsorption sites. We hereby consider chiral surfaces exhibiting (111) facets, in particular Pt(321) and Pt(643). The binding sites are either both on kink sites - which is the case for Pt(321) or on one kink site - as on Pt(643). The binding energy of the molecule on the chiral surfaces is much higher than on the Pt(111) surface. We show that the carboxyl group interacts more strongly than the hydroxyl group with the kink sites. The results reveal rather small chiral selectivities on the order of 20 meV for the Pt(321) and Pt(643) surfaces. L-lactic acid is more stable on Pt(321)$^S$ than D-lactic acid, while the chiral selectivity is inverted on Pt(643)$^S$. The most stable adsorption configurations of L- and D-lactic acid are similar for Pt(321) but differ for Pt(643). We explore the impact of the different adsorption geometries on the work function which is important for field ion microscopy.

Variability and the X-ray/UV ratio of active galactic nuclei. II. Analysis of a low-redshift Swift sample

description: Variability, both in X-ray and optical/UV, affects the well-known anti-correlation between the $α_{ox}$ spectral index and the UV luminosity of active galactic nuclei, contributing part of the dispersion around the average correlation ("intra-source dispersion"), in addition to the differences among the time-average $α_{ox}$ values from source to source ("inter-source dispersion"). We want to evaluate the intrinsic $α_{ox}$ variations in individual objects, and their effect on the dispersion of the $α_{ox}-L_{UV}$ anti-correlation. We use simultaneous UV/X-ray data from Swift observations of a low-redshift sample, to derive the epoch-dependent $α_{ox}(t)$ indices. We correct for the host galaxy contribution by a spectral fit of the optical/UV data. We compute ensemble structure functions to analyse variability of multi-epoch data. We find a strong "intrinsic $α_{ox}$ variability", which makes an important contribution ($\sim40%$ of the total variance) to the dispersion of the $α_{ox}-L_{UV}$ anti-correlation ("intra-source dispersion"). The strong X-ray variability and weaker UV variability of this sample are comparable to other samples of low-z AGNs, and are neither due to the high fraction of strongly variable NLS1s, nor to dilution of the optical variability by the host galaxies. Dilution affects instead the slope of the anti-correlation, which steepens, once corrected, becoming similar to higher luminosity sources. The structure function of $α_{ox}$ increases with the time lag up to $\sim$1 month. This indicates the important contribution of the intermediate-long timescale variations, possibly generated in the outer parts of the accretion disk.

description: Excerpts from the Preface: The primary purpose of this publication is an analysis of the operation of the so-called agricultural ladder. The method of analysis was suggested by an article published in the Quarterly Journal of Economics for May 1937, by John D. Black and R. W. Allen, entitled, "The Growth of Farm Tenancy in the United States." The authors said the purpose of their article was "to explore the evolution of the existing farm tenure situation in the United States, in general and to some extent regional, and discover its meaning and its significance for the present." The purpose of this report can be said to be the same as that of the article by Black and Allen but because the data so clearly reveal information for interpreting the operation of the agricultural ladder, it is more sharply focused on that subject. The major conclusion of this report is that a general decline in tenure status of agricultural workers between 1880 and 1940 occurred in almost every part of the United States.

description: Agile software development methods (ASD) and open source software development methods (OSSD) are two different approaches which were introduced in last decade and both of them have their fanatical advocators. Yet, it seems that relation and interface between ASD and OSSD is a fertile area and few rigorous studies have been done in this matter. Major goal of this study was assessment of the relation and integration of ASD and OSSD. Analyzing of collected data shows that ASD and OSSD are able to support each other. Some practices in one of them are useful in the other. Another finding is that however there are some case studies using ASD and OSSD simultaneously, but there is not enough evidence about comprehensive integration of them.

description: We performed a 3D radiative MHD simulation of the solar atmosphere. This simulation shows a jet-like feature that shows similarities to the type II spicules observed for the first time with Hinode. Rapid Blueshifted Events (RBEs) on the solar disk are associated with these spicules. Observational results suggest they may contribute significantly in supplying the corona with hot plasma. We perform a detailed comparison of the properties of the simulated jet with those of type II spicules (observed with Hinode) and RBEs (with ground-based instruments). We analyze variety of synthetic emission and absorption lines from the simulations including chromospheric Ca II and Ha to TR and coronal temperatures (10E4 to several 10E6K). We compare their synthetic intensities, line profiles, Doppler shifts, line widths and asymmetries with observations from Hinode/SOT and EIS, SOHO/SUMER, SST and SDO/AIA. Many properties of the synthetic observables resemble the observations, and we describe in detail the physical processes that lead to these observables. Detailed analysis of the synthetic observables provides insight into how observations should be analyzed to derive information about physical variables in such a dynamic event. For example, we find that LOS superposition in the optically thin atmosphere requires the combination of Doppler shifts and spectral line asymmetry to determine the velocity in the jet. Other properties differ from the observations, especially in the chromospheric lines. The mass density of the part of the spicule with a chromospheric temperature is too low to produce significant opacity in chromospheric lines. These and other discrepancies are described in detail, and we discuss which mechanisms and physical processes may need to be included in the MHD simulations to mimic the thermodynamic processes of the chromosphere and corona, in particular to reproduce type II spicules.

description: In this paper we show how to include low order terms in the $C^{\infty}$ well-posedness results for weakly hyperbolic equations with analytic time-dependent coefficients. This is achieved by doing a different reduction to a system from the previously used one. We find the Levi conditions such that the $C^{\infty}$ well-posedness continues to hold.

An ice wedge in Washington: a comparison of American strategy in the Arctic and Baltic theaters
Creators: name: Hussong, Lillian
Publisher: name: No Publisher Supplied
Year: 2022

description: The Arctic and the Baltics represent two abutting regions of growing geostrategic significance and concern for the United States in light of Russia’s assertive campaigns to reestablish its dominance in each region. Despite a comparable Russian threat—characterized by conventional and asymmetric military activities—the U.S. is only recently thinking about strategy in the Arctic compared to its engagement in the Baltics. When faced with a comparable Russian threat, what explains the variance in American strategy in the Arctic and the Baltics? I analyze theories of geopolitics, bureaucratic politics, and historical institutionalism to explain the gap between the U.S.' rhetoric and behavior in addressing U.S. national security, and how domestic variables influence U.S. threat perception and strategic decision-making.

description: The magnetic state and magnetic coupling of individual atoms in nanoscale structures relies on a delicate balance between different interactions with the atomic-scale surrounding. Using scanning tunneling microscopy, we resolve the self-assembled formation of highly ordered bilayer structures of Fe atoms and organic linker molecules (T4PT) when deposited on a Au(111) surface. The Fe atoms are encaged in a three-dimensional coordination motif by three T4PT molecules in the surface plane and an additional T4PT unit on top. Within this crystal field, the Fe atoms retain a magnetic ground state with easy-axis anisotropy, as evidenced by X-ray absorption spectroscopy and X-ray magnetic circular dichroism. The magnetization curves reveal the existence of ferromagnetic coupling between the Fe centers.

description: UV absorption cross sections are an essential ingredient of photochemical atmosphere models. Exoplanet searches have unveiled a large population of short-period objects with hot atmospheres, very different from what we find in our solar system. Transiting exoplanets whose atmospheres can now be studied by transit spectroscopy receive extremely strong UV fluxes and have typical temperatures ranging from 400 to 2500 K. At these temperatures, UV photolysis cross section data are severely lacking. Aims. Our goal is to provide high-temperature absorption cross sections and their temperature dependency for important atmospheric compounds. This study is dedicated to CO2, which is observed and photodissociated in exoplanet atmospheres. We also investigate the influence of these new data on the photochemistry of some exoplanets. We performed these measurements for the 115 - 200 nm range at 300, 410, 480, and 550 K. In the 195 - 230 nm range, we worked at seven temperatures between 465 and 800 K. We implemented the measured cross section into a 1D photochemical model. For wavelengths > 170 nm, the wavelength dependence of ln(cross-section_CO2(wavelength, T)x1/Qv(T)) can be parametrized with a linear law. Thus, we can interpolate cross-section_CO2(wavelength, T) at any temperature between 300 and 800 K. Within the studied range of temperature, the CO2 cross section can vary by more than two orders of magnitude. This, in particular, makes the absorption of CO2 significant up to wavelengths as high as 230 nm. The absorption cross section of CO2 is very sensitive to temperature. The model predicts that accounting for this temperature dependency of CO2 cross section can affect the computed abundances of NH3, CO2, and CO by one order of magnitude in the atmospheres of hot Jupiter and hot Neptune. This effect will be more important in hot CO2-dominated atmospheres.
