description: Based on our analysis of the contributions from the connected and disconnected contraction diagrams to the pion-kaon scattering amplitude, we provide the first determination of the only free low-energy constant at $\mathcal{O}(p^4)$, known as $L_0^r$, in SU$(4|1)$ Partially-Quenched Chiral Perturbation Theory using the data from the Extended Twisted Mass Collaboration, $L_0^r(μ=M_ρ) = 0.77(20)(25)(7)(7)(2)\cdot 10^{-3}$. The theory uncertainties originate from the unphysical scattering length, the physical low-energy constants, the higher-oder chiral corrections, the (lattice) meson masses and the pion decay constant, respectively

description: The growing importance of economics in the solution of national agricultural problems and the ever expanding scope of activity in which the Federal Government of the United States engages are each of the contributing problems to the field of Public Administration, which have made this study seem timely and worthwhile. It has been undertaken because of the writer's personal interest in agriculture and because the study of an active Bureau of the Federal Government here in Washington offers unusual opportunities for observation - especially in those times when momentous questions of public policy are flung from newspaper headlines in almost every edition.

description: Let $k$ be an infinite field of characteristic 0, and $X$ a del Pezzo surface of degree $d$ with at least one $k$-rational point. Various methods from algebraic geometry and arithmetic statistics have shown the Zariski density of the set $X(k)$ of $k$-rational points in $X$ for $d\geq2$ (under an extra condition for $d=2$), but fail to work in generality when the degree of $X$ is 1, leaving a large class of del Pezzo surfaces for which the question of density of rational points is still open. In this paper, we prove the Zariski density of $X(k)$ when $X$ has degree 1 and is represented in the weighted projective space $\mathbb{P}(2,3,1,1)$ with coordinates $x,y,z,w$ by an equation of the form $y^2=x^3+az^6+bz^3w^3+cw^6$ for $a,b,c\in k$ with $a,c$ non-zero, under the condition that the elliptic surface obtained by blowing up the base point of the anticanonical linear system $|-K_X|$ contains a smooth fiber above a point in $\mathbb{P}^1\setminus\{(1:0),(0:1)\}$ with positive rank over $k$. When $k$ is of finite type over $\mathbb{Q}$, this condition is sufficient and necessary.

Moisture Relations of Soils in Centrifugal Force Fields

Publisher: name: American University
Year: 2023

description: Studies of the physical properties of mineral soils, in both field, and laboratory, involve at least three basic factors: the mechanical composition, character of the colloid, and soil moisture. The mechanical composition of a soil is obtained by a mechanical analysis which is a quantitative expression of the relative amounts of sand, silt, clay, and perhaps colloid, of which the soil is composed. The character of the colloid is perhaps best determined by complete chemical analysis, but its character is also revealed by physical tests such as heat of wetting, water vapor absorption, and volume of floc. Numerous types of physical measurements have been made which deal with soil moisture and many terms have been coined to express the relationships found. This investigation concerns the moisture equilibrium in soils when subjected to high gravitational potentials.

description: The exceptional region of the parameter space (ERPS) of the two Higgs doublet model (2HDM) is defined to be the parameter regime where the scalar potential takes on a very special form. In the standard parameterization of the 2HDM scalar potential with squared mass parameters $m_{11}^2$, $m_{22}^2$, $m_{12}^2$, and dimensionless couplings, $λ_1$, $λ_2$, $\ldots,λ_7$, the ERPS corresponds to $λ_1=λ_2$, $λ_7=-λ_6$, $m_{11}^2=m_{22}^2$ and $m_{12}^2=0$, corresponding to a scalar potential with an enhanced generalized CP symmetry called GCP2. Many special features persist if $λ_1=λ_2$ and $λ_7=-λ_6$ are retained while allowing for $m_{11}^2\neq m_{22}^2$ and/or $m_{12}^2\neq 0$, corresponding to a scalar potential with a softly-broken GCP2 symmetry, which we designate as the ERPS4. In this paper, we examine many of the special features of the ERPS4, as well as even more specialized cases within the ERPS4 framework in which additional constraints on the scalar potential parameters are imposed. By surveying the landscape of the ERPS4, we complete the classification of 2HDM scalar potentials that exhibit an exact Higgs alignment (where the tree-level couplings of one neutral scalar coincide with those of the Standard Model Higgs boson), due to a residual symmetry that is unbroken in the vacuum. One surprising aspect of the ERPS4 is the possibility that the scalar sector is CP-conserving despite the presence of a complex parameter of the scalar potential whose complex phase cannot be removed by separate rephasings of the two scalar doublet fields. The significance of the ERPS4 regime for custodial symmetry is also discussed, and the cases where a custodial symmetric 2HDM scalar potential preserves an exact Higgs alignment are elucidated.

The intermediate neutron capture process. I. Development of the i-process in low-metallicity low-mass AGB stars

description: Results from observations report a growing number of metal-poor stars showing an abundance pattern midway between the s- and r-processes. These so-called r/s-stars raise the need for an intermediate neutron capture process (i-process), which is thought to result from the ingestion of protons in a convective helium-burning region, but whose astrophysical site is still largely debated. We investigate whether an i-process during the asymptotic giant branch (AGB) phase of low-metallicity low-mass stars can develop and whether it can explain the abundances of observed r/s-stars. At the beginning of the AGB phase, during the third thermal pulse, the helium driven convection zone is able to penetrate the hydrogen-rich layers. The subsequent proton ingestion leads to a strong neutron burst with neutron densities of $\approx 4.3 \times 10^{14}$ cm$^{-3}$ at the origin of the synthesis of i-process elements. The nuclear energy released by proton burning in the helium-burning convective shell strongly affects the internal structure: the thermal pulse splits and after approximately ten years the upper part of the convection zone merges with the convective envelope. The surface carbon abundance is enhanced by more than 3 dex. This leads to an increase in the opacity, which triggers a strong mass loss and prevents any further thermal pulse. We show that specific isotopic ratios of Ba, Nd, Sm, and Eu can represent good tracers of i-process nucleosynthesis. Finally, an extended comparison with 14 selected r/s-stars show that the observed composition patterns can be well reproduced by our i-process AGB model.

A study of the broader responsibilities of supervisory officers in handling government employees, with special reference to the Forest Service
Creators: name: Flock, Kester D.
Publisher: name: American University
Year: 2023

description: Supervisors of workers in general are charged with obtaining results that meet measurable standards in quantity and quality. These standards are based on past experience under similar or comparable conditions and verifications of forecasts are often obtained by time and motion studies of some form that will fit the situation. In the process of production, human beings and machines are combined in varying proportions to work with raw materials and out of the controlled processes come desired results in the form of consumption goods, more production goods or services that are put to further use to benefit human existence. Science has devised ways of controlling combinations of raw materials and means of treatment so the results will satisfy specific needs. Machines used in processing and fabrication are under control regarding design and speed of performance to a nice degree and some progress has been made in controlling human performance. Most progress has been made, however, in manufacturing under the assembly line system where every operation is subject to measurement over short periods. The employee in this type of work either produces up to standard or he does not. There is a very narrow margin of variance for the foreman, superintendent or supervisory officer to measure; therefore, his training for overseeing his workers is easily acquired and applied in a comparatively simple manner. He has little apparent reason to use knowledge of human behavior and fills his job quite satisfactorily with his rules of thumb and ease of measuring results, backed up by power of quick demotion or dismissal for obvious failure on the part of those under his supervision. The purpose of this thesis is to point out the problems that exist because of the inadequacy of our training in proper personnel procedure among supervisory officers in the Forest Service in particular and furnish case studies and reference material that will assist those who wish to improve themselves.
title: Antizipation beim Simultandolmetschen
Creators: name: Koch, Gorana
Year: 2017

description: SimultandolmetscherInnen sind bei syntaktisch unterschiedlichen Sprachkombinationen mit ganz eigenen Schwierigkeiten konfrontiert. Sprachenpaarspezifische syntaktische Unterschiede können unter anderem dazu führen, dass die Simultan-dolmetscherInnen mit einem größeren time lag dolmetschen und dadurch die kurzfristige Speicherkapazität übermäßig beanspruchen. Spezielle Dolmetschstrategien, wie etwa die Antizipation, können daher hilfreich sein, diese Herausforderungen zu bewältigen. Diese Arbeit ist die erste Antizipationsstudie der Sprachkombination Deutsch-Kroatisch. Die zentrale Forschungsfrage stellt sich wie folgt: Bedienen sich kroatische DolmetscherInnen der Strategie der Antizipation, um Schwierigkeiten aufgrund syntaktischer und struktureller Unterschiede zwischen dem Deutschen und Kroatischen zu überwinden? Dabei werden die Häufigkeit und die Genauigkeit sowie die grammatikalischen Komponenten und Auslöser der Antizipationen untersucht. Als Korpusmaterial dienen insgesamt 29 Reden auf Deutsch, die während Plenarsitzungen des Europäischen Parlaments im Jahr 2016 zur Flüchtlingsthematik gehalten wurden, sowie deren Verdolmetschungen ins Kroatische. Die Ergebnisse der Korpusanalyse zeigen, dass die kroatischen Dolmetscherinnen die Antizipation als Strategie einsetzen. Entgegen den Erwartungen, welche auf vergleichbaren Analysen mit anderen Sprachenpaaren basieren, wird deutlich weniger antizipiert. Dafür gibt es aber keine einzige falsche Antizipation. Des Weiteren werden auch die antizipierten grammatikalischen Bestandteile sowie Auslöser der Antizipation untersucht. Es zeigt sich erwartungsgemäß, dass mehr Verben als Negationen antizipiert werden. Am häufigsten werden syntaktische Auslöser gezählt.

description: CUORE Upgrade with Particle IDentification (CUPID) is a next-generation search for neutrinoless double-beta decay which will use light from cryogenic calorimeters to tag particles by their heat-to-light signal ratio. CUPID is under development at the 250 kg level, but is already looking to the next tonne stage: CUPID-1T. Scaling the next generation of crystalline detectors to this size requires tens of thousands of channels, as well as advancements in background rejection; R&D efforts underway towards this goal are discussed. We focus on the DEMETER project, a collaboration between UC Berkeley and Lawrence Berkeley National Laboratory toward implementation of a multiplexed readout and event discrimination at the single-crystal level. DEMETER's modular design supports testing both Li2100MoO4 (scintillation) and TeO2 (Cherenkov) as candidate calorimeters, as well as multiple readout schemes. We present both simulation and hardware advancements toward DEMETER, which will inform design choices for the next-to-next generation cryogenic calorimeter search for neutrinoless double-beta decay.
title: Kirchendolmetschen in rumänischen Pfingstgemeinden in Österreich
Creators: name: Chezan, Andrea

description: Ziel der vorliegenden Arbeit ist es, Kirchendolmetschen in rumänischen Pfingstkirchen in Österreich darzustellen, und zwar anhand von Beobachtungen und Analysen einer Kirchendolmetscherin in einer rumänischen Pfingstkirche. Dabei sollen folgende Fragen beantwortet werden: Wer sind die Kirchendolmetscher? Nach welchen Kriterien werden sie ausgewählt? Welche sind ihre Arbeitsbedingungen? Gewählt wurde der (auto)ethnographische Forschungsansatz, bei dem die for- schende Person direkt im Forschungsfeld, hier die Pfingstkirche, mit der Dolmetscherin arbeitet. Als Datenquellen dienten eine Audio- und Videoaufnahme, Transkriptionen, ein Fragebogen und eigene Notizen und Beobachtungen. Die Ergebnisse der Beobachtungen und Analyse zeigen, dass die Kirchendol- metscherin – wie in den meisten Fällen üblich – aus der eigenen Kirche und als Laien- dolmetscher tätig sind. Durch ihre langjährige Dolmetschtätigkeit in der Kirche, konnte sich die beobachtete Dolmetscherin nach dem Prinzip Learning by Doing ein Repertoir an bestimmten Strategien aneignen, die sie auch bewusst wählt. In ihrem Handeln und Verhalten positioniert sich die Dolmetscherin zuerst auf die Seite der Kirche und sieht sich dabei als Werkzeug Gottes, dessen Aufgabe es ist, zu entscheiden was für den Zu- hörer angemessen oder unangemessen ist.
description: The focus of this thesis lies in describing church interpreting in Romanian Pentecostal churches. This is achieved by observations and analysis of one church interpreter in a Romanian Pentecostal church. The following questions are answered: Who are the church interpreters? According to what criteria are they chosen? What are their working conditions? The research approach was based on Autoethnography, where the researcher is working directly in the field, here the Pentecostal church, with the church interpreter. Data were collected by audio and video recordings, transcriptions, one questionnaire and notes and observations. The results show that church interpreters – as in most cases – are church mem- bers and working as lay interpreters. Due to her long interpreting activity in the church, the observed church interpreter was able, following the principle of learning by doing, to pool a number of strategies, which she chooses wittingly. Through her actions and behaviour, the church interpreter positions herself primarily on the church’s side, seeing herself as working as God’s tool who has to decide what is appropriate for the listener and what is not.

description: An integral equation-based approach for the design of dual band stacked metasurfaces which are invariant in one-dimension is presented. The stacked metasurface will generate collimated beams at desired angles in each band upon reflection. The conductor-backed stacked metasurface consists of two metasurfaces (a patterned metallic cladding supported by a dielectric spacer) stacked one upon the other. The stacked metasurface is designed in three phases. First the patterned metallic cladding of each metasurface is homogenized and modeled as an inhomogeneous impedance sheet. An Electric Field Integral Equation (EFIE) is written to model the mutual coupling between the homogenized elements within each metasurface, and from metasurface to metasurface. The EFIE is transformed into matrix equations by the method of moments. The nonlinear matrix equations are solved at both bands iteratively resulting in dual band complex-valued impedance sheets. In the second phase, optimization is applied to transform these complex-valued impedance sheets into purely reactive sheets suitable for printed circuit board fabrication by introducing surface waves. In the third phase, the metallic claddings of each metasurface are patterned for full-wave simulation of the dual band stacked metasurface. Using this approach, two dual band stacked metasurfaces are designed

description: For robots navigating using only a camera, illumination changes in indoor environments can cause re-localization failures during autonomous navigation. In this paper, we present a multi-session visual SLAM approach to create a map made of multiple variations of the same locations in different illumination conditions. The multi-session map can then be used at any hour of the day for improved re-localization capability. The approach presented is independent of the visual features used, and this is demonstrated by comparing re-localization performance between multi-session maps created using the RTAB-Map library with SURF, SIFT, BRIEF, BRISK, KAZE, DAISY and SuperPoint visual features. The approach is tested on six mapping and six localization sessions recorded at 30 minute intervals during sunset using a Google Tango phone in a real apartment.

description: The aim of this work is to investigate the occurrence of two different spontaneous symmetry breakings {at} two levels of the description of fermion-scalar field model, by means of a set of gap equations and {with} a background field effective action. For that, we consider the Yukawa model, as a toy model for interactions between non-massive fermions intermediated by a self-interacting real scalar field. This model has at stakes two symmetries at the classical level that, as we know, might be spontaneously or dynamically broken with mass generation for the particles. The auxiliary field method is considered and it produces coupled renormalized gap equations. The effective action is then written with quantum contributions by {the} external background {field} method. We brought to light how the renormalization procedure affects the physical gaps, investigate its properties, and discuss the connection between the auxiliary fields not only to define composite states but also to compute the effective action.

The purpose of this thesis is to point out the problems that exist because of the inadequacy of our training in proper personnel procedure among supervisory officers in the Forest Service in particular and furnish case studies and reference material that will assist those who wish to improve themselves.
title: Die Sicht der DolmetscherInnen beim Simultandolmetschen
Creators: name: Nyvlt, Marco
Year: 2017

description: In dieser Arbeit wird der visuelle Zugang von DolmetscherInnen beim Simultandolmetschen betrachtet. Es wird im Rahmen eines Experiments die direkte Sicht mit der Sicht über einen Bildschirm verglichen, und ob es sich auf die Qualität der Dolmetschleistung auswirkt bzw. wie die DolmetscherInnen die Sichtmodi wahrnehmen. Die Auswertung ergab, dass die Qualität bei keinem der beiden Sichtmodi eindeutig besser wäre, sondern, dass die Leistungen bezüglich der Sichtmodi von Person zu Person unterschiedlich sind. Auf der Grundlage von Probandeninterviews wird gezeigt, dass die DolmetscherInnen die jeweiligen Sichtmodi aufgrund ihrer subjektiven Wahrnehmung beurteilen, dass es sich aber nicht immer in der Dolmetschqualität widerspiegelt. Keiner der Sichtmodi kann demnach unabhängig von der Person und Situation mit einer besseren Leistung in Verbindung gebracht werden.
description: This thesis discusses visual access of interpreters in simultaneous interpreting. Two methods of visual access, direct sight and sight via screen, are compared in an experiment focusing on whether these affect the quality of interpreting performance and whether interpreters’ perception of these viewing methods varies. The evaluation shows that the interpreters’ performance is not significantly better with either method and that performance varies in relation to visual access from person to person. Interviews of the participants show that the two methods are perceived individually and that there is not necessarily a correlation between perception of the situations and performance quality. Hence, without taking the person and situation into consideration, neither method is linked with distinctly better interpreting performance.

description: When a light beam is strongly laterally confined, its field vector spins in a plane not perpendicular to the propagation direction, leading to the presence of transverse spin angular momentum, which plays a crucial role in the field of chiral quantum optics. The existing techniques to measure the transverse spin density require complex setups and sophisticated time-consuming procedures. Here, we propose a scheme to measure the transverse spin density of an optical field in real time using a multi-level atomic medium. The susceptibility of the medium is spatially modulated by the transverse spin via electromagnetically induced transparency. The distribution of the transverse spin is then extracted by measuring the distributions of the Stokes parameters of another collimated probe field.

description: The pion and kaon properties in a nuclear medium at nonvanishing temperature as well as the QCD chiral condensate in the presence of a magnetic field for various baryon densities are studied in the Nambu-Jona-Lasinio (NJL) model with the help of the proper-time regularization (PTR) scheme, simulating a QCD confinement. The density dependent of the quark mass in symmetric nuclear matter is obtained from the quark-meson coupling (QMC) model, which shares the same covariant feature with the NJL model, at quark level. We then analyze the QCD chiral condensates, and dynamical masses for various baryon densities at finite temperature and magnetic field as well as the pion and kaon masses, pion and kaon weak-decay constants, pion-and kaon-quark coupling constants, and wave function renormalization factors for various baryon densities at finite temperature. We find that the QCD chiral condensates suppress with increasing temperature and baryon density and enhance under the presence of a magnetic field, which are consistent with other model predictions. Interestingly, the wave function renormalization factors for the pion and kaon increase with respect to temperature and reduce as the baryon density increases are found.

title: Die Rolle der DolmetscherInnen an den europäischen Außengrenzen
Creators: name: Cirello, Giuditta Salvina
Year: 2017

description: Die vorliegende Masterarbeit untersucht die Rolle von DolmetscherInnen an den europäischen Außengrenzen. Die Hotspots sind täglich mit ankommenden Flüchtlingen konfrontiert und benötigen dementsprechend einen hohen Bedarf an Dolmetschleistungen. Im Mittelpunkt steht die Tätigkeit von DolmetscherInnen bei der Ankunft der Flüchtlinge: Diese werden zuerst von nationalen und internationalen Organisationen rechtlich beraten und danach von Frontex-Fachkräften registriert. Die an den europäischen Grenzen geltenden Gesetze und Richtlinien werden daher in dieser Arbeit analysiert, um die Rahmenbedingungen dieses Einsatzbereichs, der in dieser Arbeit Hotspot-Dolmetschen genannt wird, zu skizzieren. Der Bereich Hotspot-Dolmetschen weist Eigenschaften sowohl vom Asyldolmetschen als auch vom Polizeidolmetschen auf, da Hotspot-DolmetscherInnen mit Asylbehörden und mit Polizeikräften zusammenarbeiten. Aus diesem Grund sind beide Bereiche dargestellt, um die Eigenschaften des Hotspot-Dolmetschens zu identifizieren. Die Rolle und die Qualifizierung der Hotspot-DolmetscherInnen werden auch in Betracht gezogen. Um die Arbeitspraxis der Hotspot-DolmetscherInnen angemessen beschreiben zu können, wurden sechs Interviews mit Hotspot-DolmetscherInnen, die in Griechenland oder Italien arbeiten, geführt. Anhand der Literatur sind die Interviews analysiert worden. Dabei stehen folgende Punkten im Fokus: Die Änderungen in der Kommunikation durch die Anwesenheit der DolmetscherInnen; die Kommunikationshindernisse, die sowohl aufgrund der sprachlichen und kulturellen Unterschiede als auch wegen der Komplexität des Asylsystems entstehen können; die gespielte Rolle der interviewten DolmetscherInnen und deren Qualifikation.
Some factors affecting the vitality of local 4-H clubs

description: This study deals with the vitality of local 4-H Clubs. The word vitality is interpreted as meaning both the animate existence and the power of enduring or continuing. The problem is to determine some of the factors which are present in the organization and conduct of 4-H Clubs which means for some only a year or two of existence and for others a long life and a well integrated position in the community. The study is to be made in a form and in terms that will be useful to the thousands of county and State extension workers who are confronted with this problem. There has been no direct study made of this particular place of 4-H Club work although the problem has been mentioned by several in other 4-H Club studies.

Graph Signal Processing: Dualizing GSP Sampling in the Vertex and Spectral Domains

description: Vertex based and spectral based GSP sampling has been studied recently. The literature recognizes that methods in one domain do not have a counterpart in the other domain. This paper shows that in fact one can develop a unified graph signal sampling theory with analogous interpretations in both domains just like sampling in traditional DSP. To achieve it, we introduce a spectral shift $M$ acting in the spectral domain rather than shift $A$ that acts in the vertex domain. This leads to a GSP theory that starts from the spectral domain, for example, linear shift invariant (LSI) filtering in the spectral domain is with polynomials $P(M)$. We then develop GSP vertex and spectral domain dual versions for each of the four standard sampling steps of subsampling, decimation, upsampling, and interpolation. We show how GSP sampling reduces to DSP sampling when the graph is the directed time cycle graph. Simple examples illustrate the impact of choices that are available in GSP sampling.

description: We address the problem of output prediction, ie. designing a model for autonomous nonlinear systems capable of forecasting their future observations. We first define a general framework bringing together the necessary properties for the development of such an output predictor. In particular, we look at this problem from two different viewpoints, control theory and data-driven techniques (machine learning), and try to formulate it in a consistent way, reducing the gap between the two fields. Building on this formulation and problem definition, we propose a predictor structure based on the Kazantzis-Kravaris/Luenberger (KKL) observer and we show that KKL fits well into our general framework. Finally, we propose a constructive solution for this predictor that solely relies on a small set of trajectories measured from the system. Our experiments show that our solution allows to obtain an efficient predictor over a subset of the observation space.

The Characterology of Eduard Spranger as a Contribution to a Philosophy of Education
Creators: name: Eckhart, Ruth Alma
Publisher: name: American University

description: The thesis project originally approved was a translation, with critical comment, of Eduard Spranger's Lebensformen, a work which no English or American publisher had undertaken to introduce to the English-speaking public. It was discovered, however, that an English translation made by Mr. Paul J.W. Pigors of Harvard University had been published in Germany under the title Types of Men. Accordingly the plan of the present study was changed in favor of a critique of Spranger's basic teachings, to be made from the specific point of view indicated in the title, with especial reference to the educational needs of contemporary America.
