description: The Grand Tack model of terrestrial planet formation has emerged in recent years as the premier scenario used to account for several observed features of the inner solar system. It relies on early migration of the giant planets to gravitationally sculpt and mix the planetesimal disc down to ~1 AU, after which the terrestrial planets accrete from material left in a narrow circum-solar annulus. Here we have investigated how the model fares under a range of initial conditions and migration course-change (`tack') locations. We have run a large number of N-body simulations with a tack location of 1.5 AU and 2 AU and tested initial conditions using equal mass planetary embryos and a semi-analytical approach to oligarchic growth. We make use of a recent model of the protosolar disc that takes account of viscous heating, include the full effect of type 1 migration, and employ a realistic mass-radius relation for the growing terrestrial planets. Results show that the canonical tack location of Jupiter at 1.5 AU is inconsistent with the most massive planet residing at 1 AU at greater than 95% confidence. This favours a tack farther out at 2 AU for the disc model and parameters employed. Of the different initial conditions, we find that the oligarchic case is capable of statistically reproducing the orbital architecture and mass distribution of the terrestrial planets, while the equal mass embryo case is not.

Cruel girlhood: violent practices and Chinese schoolgirls in films and fiction
Creators: name: Xiang, Lidong
Publisher: name: No Publisher Supplied
Year: 2023

description: This dissertation focuses on violent practices and Chinese schoolgirls in films and fiction. By bringing together a wide range of scholarly fields and areas of interest, the overall research articulates the entangled historical and contemporary violent practices and the resistant agency of schoolgirls. This project highlights the structured ways of literary and cinematic narratives that are embedded in schoolgirls’ recurring experiences and mediated through historically specific discourses and various contexts. The tension between the idealized view and the stigmatization of Chinese schoolgirls is closely associated with various and perpetuated violent practices across decades of fantasizing about Chinese girlhood and is integrated into the broader cultural logic and the political climate. The methodological approach combines feminist studies with a multidisciplinary perspective informed by archival research, visual and literary analysis, and the investigation of material realities. Each of the content chapters traces the historical trajectory of the Chinese schoolgirl figure under different predominant violent practices since Republican China (1912-1949). I complement this archival research with literary and visual analysis of newspapers and periodicals discussing schoolgirls, women’s autobiographical writings about their girlhood and those written by girls themselves, contemporary children’s books and adult novels, and cinematic narratives of schoolgirls. The close textual and visual readings of the representative works interweave with and are strengthened by contextualized analysis of material realities that make violent operations on fantasizing schoolgirls visible and interrogated. For example, the complexly interlinked realities include paratextual elements (such as book covers in different editions and translated versions) of the books, transnational circulation of both films and fiction, publishing process and censorship, geopolitics, and sociocultural systems that jointly and constantly project the fantasy of schoolgirls. This dissertation traces how violent practices derived from the shaming punishments of the Socialist era and have evolved into various contemporary forms such as intimate and internalized manipulation, intergenerational oppression of feminine desires and non-normative behaviors, material and infrastructural violence embedded in bodies and spatial relations. It explores how schoolgirls in their classed, gendered, and aged bodily constructions are connected to wider political and social relations, knowledge practices, and social justice.
Functional characterization of a novel gene in ABA signaling in Arabidopsis thaliana
Creators: name: Schwarz, Maria Katherine
Publisher: name: No Publisher Supplied
Year: 2023

description: Stomata, microscopic pores on the aerial surface of leaves that facilitate gas exchange between plants and the atmosphere, are one of the crucial structures to preserve water within plants. The phytohormone abscisic acid (ABA), responds to stressful environments and triggers a series of plant responses to prevent water loss, such as regulation of stomatal conductance. ABA homeostasis is dynamically regulated by a variety of processes, including ABA biosynthesis, ABA catabolism, ABA transport and ABA signaling. ABA is synthesized and transported in vascular tissues. Many genes have been identified to regulate ABA in the model plants Arabidopsis thaliana. For instance, the ABA1 and ABA2 genes are involved in ABA biosynthesis, the CYP707A family of genes are involved in ABA catabolism, and the proteins encoded by ABI1 and ABI2 genes act as repressors in ABA signaling. We identified a novel gene in plant drought tolerance. In this study, by genetically manipulating the ABA quantities and ABA signaling in the novel mutant, we intend to characterize the function of our novel gene in ABA signaling and thus plant drought tolerance.

description: The Faraday effect is a representative magneto-optical phenomenon, resulting from the transfer of angular momentum between interacting light and matter in which time-reversal symmetry has been broken by an externally applied magnetic field. Here we report on the Faraday rotation induced in the prominent 3D topological insulator Bi2Se3 due to bulk interband excitations. The origin of this non-resonant effect, extraordinarily strong among other non-magnetic materials, is traced back to the specific Dirac-type Hamiltonian for Bi2Se3, which implies that electrons and holes in this material closely resemble relativistic particles with a non-zero rest mass.

description: The purpose of this study was to test the relationship between regular aerobic exercise and body weight. It was the intent of this study to determine if a person who regularly exercises at either high or moderate levels can maintain their body weight at desired levels as specified by the Body Mass Index (BMI). The participants in this study were selected from hospital employees, class members of aerobic classes and/or adult walkers/joggers. There were 38 participants-- 13 males and 25 females.

A self administered questionnaire and a 3-day, 24-hour dietary log were identified to comprise the instrument as well as measures of the socio-economic, demographic, behavioral, educational, physical activity levels of the participants in the study.

The study employed two approaches: (1) a descriptive analysis of the demographic variables, and (2) a statistical analysis utilizing Chi-Square analysis and the t-test to determine relationships between the amount of calories, protein, carbohydrates and fat consumed on the three days.

The Chi-Square test produced the following results: (1) the variable sex was the most significant predictor of body weight; and (2) sex, eating balanced meals, and height were identified as significant predictors of weight. The t-test revealed no significant difference between the amount of calories, percentage of calories from protein, the percentage of calories from carbohydrates, and the percentage of calories from fats consumed on three days.

description: Operation and performance of the Resistive Plate Chambers (RPCs) mostly depend on the quality and characteristics of the electrode materials. The India-based Neutrino Observatory collaboration has chosen glass RPCs as the active detector elements for its Iron Calorimeter detector and is going to deploy RPCs in an unprecedented scale. Therefore, it is imperative that we study the electrode material aspects in detail. We report here, systematic characterization studies on the glasses from two manufacturers. RPC detectors were built using these glasses and performances of the same were compared with their material properties.
title: Effects of Applied Soil Repellent Finish on Pesticide Residues in Work Clothing

Publisher: name: Old Dominion University Libraries
Year: 1990

description: This study explores the feasibility of using an applied soil repellent finish, Scotchgard, on 100% cotton denim fabric in order to enhance the removal of atrazine and alachlor residue during the laundering process. The experimental findings provided no statistically significant evidence that Scotchgard fabric protector reduced pesticide residuals on the 100% cotton denim fabric either before or after laundering. A significant finding secondary to the study involved the possible interaction of Scotchgard with the pesticide alachlor, leaving greater amounts of residual on the fabric after laundering than those found with no fabric treatment. This suggests that agricultural workers be cautioned against using Scotchgard fabric protector as a means of protection from pesticide liquids until further studies can be conducted and a data registry established.

description: We have investigated the exciton dynamics in transition metal dichalcogenide mono-layers using time-resolved photoluminescence experiments performed with optimized time-resolution. For MoSe2 monolayers, we measure $τ_{rad}=1.8\pm0.2$ ps that we interpret as the intrinsic radiative recombination time. Similar values are found for WSe2 mono-layers. Our detailed analysis suggests the following scenario: at low temperature (T $\leq$ 50 K), the exciton oscillator strength is so large that the entire light can be emitted before the time required for the establishment of a thermalized exciton distribution. For higher lattice temperatures, the photoluminescence dynamics is characterized by two regimes with very different characteristic times. First the PL intensity drops drastically with a decay time in the range of the picosecond driven by the escape of excitons from the radiative window due to exciton- phonon interactions. Following this first non-thermal regime, a thermalized exciton population is established gradually yielding longer photoluminescence decay times in the nanosecond range. Both the exciton effective radiative recombination and non-radiative recombination channels including exciton-exciton annihilation control the latter. Finally the temperature dependence of the measured exciton and trion dynamics indicates that the two populations are not in thermodynamical equilibrium.

description: Thin films of superfluid $^3$He were predicted, based on weak-coupling BCS theory, to have a stable phase which spontaneously breaks translational symmetry in the plane of the film. This crystalline superfluid, or "stripe" phase, develops as a one dimensional periodic array of domain walls separating degenerate B phase domains. We report calculations of the phases and phase diagram for superfluid $^3$He in thin films using a strong-coupling Ginzburg-Landau theory that accurately reproduces the bulk $^3$He superfluid phase diagram. We find that the stability of the Stripe phase is diminished relative to the A phase, but the Stripe phase is stable in a large range of temperatures, pressures, confinement, and surface conditions.

description: Excerpts from the report Introduction: Many irrigation projects have been developed in the Western States. The legal forms of the organizations under which they were set up included irrigation districts and several types of both mutual and commercial companies. Some of the projects failed; others have been successful throughout their history. Because many more such projects are likely to be developed in the future, the Soil Conservation Service and the Bureau of Agricultural Economics of the United States Department of Agriculture undertook a study of these various types of organizations. Field work for the study was conducted chiefly in 1946 and 1947. A progress report was submitted by the authors to the participating agencies in October 1948 for the immediate use of those agencies. This report summarizes the results of the study and coordinates them with those from previous studies of such organizations. From the study an attempt was made to learn not only the advantages and disadvantages of each type of organization in the development and operation of irrigation projects but also the influence of the various provisions of pertinent Federal and State laws on the solution of problems that arise in managing such enterprises.

On the road to building a universal circadian rhythm model
Creators: name: Mansour, Omar
Publisher: name: No Publisher Supplied
Year: 2023

description: Historically, there have been two theories describing entrainment; the discrete theory and the continuous theory. The discrete theory implies that entrainment happens as a result of an instantaneous abrupt phase shift of the internal clock caused by zeitgeber signals at zeitgeber transitions. The continuous theory implies that entrainment happens as a result of a continuous gradual change of the phase of the internal clock caused by zeitgeber signals throughout the day. The discreet theory has been formulated through the phase response curve (PRC) and the phase of entrainment equation. While the PRC has been used prominently in the field, there has not been a formulation of the continuous theory that has been used as prominently. Recently, the continuous theory has been formulated through the Circadian integrated Response Characteristic (CiRC), and, CiRC is also a formulation of the discrete theory. Therefore, CiRC can be considered a formulation that unified both theories of entrainment. Our lab, in a previous study, developed a circadian rhythm model named dynamic CiRC (dCiRC), which is a system of Ordinary Differential Equations (ODEs) that utilizes the CiRC formulation, and uses it to extract the real-time dynamic changes of the internal clock. dCiRC is a tool that allows researchers to study how entrainment occurs and investigate the mechanism by which it occurs. Our lab, in a previous study, demonstrated dCiRC’s ability to fit to and describe light entrained data with a light cycle of a 50% photoperiod. In this study, we demonstrate the versatility of the dCiRC model by showing that it can fit to and describe temperature entrained data with temperature cycles of thermoperiods ranging from 16% to 84%. Our results suggest that organisms may entrain as the discrete theory implies in short thermoperiods and as the continuous theory implies in long thermoperiods. Our results also show conditions where an organism is entrained by a combination of mechanisms from both theories. Our study demonstrates how the dCiRC model can be used to better understand and formalize how entrainment happens, potentially resolving ambiguities present in the field for decades regarding the entrainment process.

description: A new exact and analytic solution of non-relativistic fireball hydrodynamics is presented. It describes an expanding triaxial ellipsoid that rotates around one of its principal axes. The observables are calculated using simple analytic formulas. Azimuthal oscillation of the off-diagonal Bertsch-Pratt radii of Bose-Einstein correlations as well as rapidity dependent directed and third flow measurements provide means to determine the magnitude of the rotation of the fireball. Observing this rotation and its dependence on collision energy may lead to new information on the equation of state of the strongly interacting quark gluon plasma produced in high energy heavy ion collisions.

description: It has recently been shown that BMS supertranslation symmetries imply an infinite number of conservation laws for all gravitational theories in asymptotically Minkowskian spacetimes. These laws require black holes to carry a large amount of soft ($i.e.$ zero-energy) supertranslation hair. The presence of a Maxwell field similarly implies soft electric hair. This paper gives an explicit description of soft hair in terms of soft gravitons or photons on the black hole horizon, and shows that complete information about their quantum state is stored on a holographic plate at the future boundary of the horizon. Charge conservation is used to give an infinite number of exact relations between the evaporation products of black holes which have different soft hair but are otherwise identical. It is further argued that soft hair which is spatially localized to much less than a Planck length cannot be excited in a physically realizable process, giving an effective number of soft degrees of freedom proportional to the horizon area in Planck units.

Closing the turnout gap: can strengthening motivation - or planning - drive young potential voters to the polls?
Creators: name: Grady, Grace Evangeline
Publisher: name: No Publisher Supplied
Year: 2023

description: Voting rates among young Americans are consistently low, even among young Americans who report intending to vote. Well-funded “get out the vote” (GOTV) campaigns have shown minimal effects on turnout. Multiple explanations have been suggested, including a lack of motivation, or lack of ability to follow through on voting intentions. This study used an online survey methodology to build on prior research by testing the effectiveness of two novel, theory- based GOTV interventions to increase turnout among young potential voters (ages 18-29), utilizing random assignment and a control group. A “Why to Vote” (WTV) intervention aimed to increase turnout by strengthening existing beliefs and increasing the perceived efficacy of voting. This intervention integrated voting within a narrative of action that one can take to reach desired outcomes. A “How to Vote” (HTV) intervention tested whether low youth voter turnout results from failure to overcome obstacles to following through on vote intentions. This intervention walked participants through (1) practice navigating online state online election tools; (2) making a plan to vote; and (3) making back-up plans against obstacles often faced by young voters. We used manually validated vote as a rigorous dependent variable to observe whether, as hypothesized, turnout in each of the two intervention groups in five U.S. states was higher than in a filler-task control group. Results indicated that participants in the HTV intervention group were more likely to turnout versus the control group, while participants in the WTV intervention group were not. While a large number of alternative explanations were considered via controlled, mediation, and moderation models, only participant age was found to moderate the effects of the HTV intervention on turnout: as hypothesized, younger HTV participants were more likely to turnout. Limitations, implications, and avenues for future research (including the manual validation of voter turnout) are discussed.

Así, se constituyen en enunciados antinormativos corteses, en la medida que no siguen las normas de la sociedad, pero cumplen la función de reforzar sus lazos de amistad. Para ello, se llevó a cabo un recorrido etnográfico en la zona suroriental de la ciudad de Cartagena mediante la observación participante, teniendo en cuenta el contexto, la situación comunicativa y las características socioculturales de los participantes, apoyándonos en las teorías de autores importantes en campo de la pragmática como: Brown y Levinson (1987), Escandell (1995, 1996) y Zimmerman (2005).

description: This report is intended primarily for Dutch policymakers. In addition, it aims to describe, for a criminological audience, the research design and analysis methods of the Recidivism 1977 research project. Consequently, the report contains both a Dutch overview of the research and an extensive English review containing methodological details. The Dutch overview contains only the most important tables and figures, but discussen findings that are layed out in precise detail in the English section of the report. This report asks the following question: Of those people found guilty of a criminal offense in the Netherlands in 1977, was there a group of particularly active and dangerous people, who would be responsible within the next six years for serious crimes out of proportion to their numbers?

description: We report valence band electronic structure evolution of graphene oxide (GO) upon its thermal reduction. Degree of oxygen functionalization was controlled by annealing temperatures, and an electronic structure evolution was monitored using real-time ultraviolet photoelectron spectroscopy. We observed a drastic increase in density of states around the Fermi level upon thermal annealing at ~600 oC. The result indicates that while there is an apparent band gap for GO prior to a thermal reduction, the gap closes after an annealing around that temperature. This trend of band gap closure was correlated with electrical, chemical, and structural properties to determine a set of GO material properties that is optimal for optoelectronics. The results revealed that annealing at a temperature of ~500 oC leads to the desired properties, demonstrated by a uniform and an order of magnitude enhanced photocurrent map of an individual GO sheet compared to as-synthesized counterpart.

description: No es una novedad que la educación y la filosofía compartan sólo una responsabilidad magna en la sociedad, sino una vital función formadora a nivel de conciencia y experiencias de vida; la transformación y progreso de la misma es un asunto de gran importancia para la humanidad. Tomando conciencia respecto a las diversas problemáticas sociales del contexto latinoamericano, buscaremos analizar la relevancia de la educación en nuestra realidad actual para determinar de qué manera la transformación social a nivel estructural necesita de una redefinición del enfoque del sistema educativo. Toda sociedad que atreviese por dificultades históricas, sobre todo cuando estas dificultades están marcadas por violencia y la guerra política, las desigualdades sociales y la discriminación radical de la población campesinas, debe apuntar a un duro, lento pero necesario proceso de transformación de sus estructuras sociales, esto implica una reelaboración de la visión que se tiene de la moralidad y la cultura.

description: We present the quantitative phase diagram of the bilayer bosonic fractional quantum Hall system on the torus geometry at total filling factor $ν=1$ in the lowest Landau level. We consider short-range interactions within and between the two layers, as well as the inter-layer tunneling. In the fully polarized regime, we provide an updated detailed numerical analysis to establish the presence of the Moore-Read phase of both even and odd numbers of particles. In the actual bilayer situation, we find that both inter-layer interactions and tunneling can provide the physical mechanism necessary for the low-energy physics to be driven by the fully polarized regime, thus leading to the emergence of the Moore-Read phase. Inter-layer interactions favor a ferromagnetic phase when the system is $SU(2)$ symmetric, while the inter-layer tunneling acts as a Zeeman field polarizing the system. Besides the Moore-Read phase, the $(220)$ Halperin state and the coupled Moore-Read state are also realized in this model. We study their stability against each other.
