On the suppression of the diffusion and the quantum nature of a cavity mode. Optical bistability; forces and friction in driven cavities
Creators: name: Murr, K.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A new analytical method is presented here, offering a physical view of driven cavities where the external field cannot be neglected. We introduce a new dimensionless complex parameter, intrinsically linked to the cooperativity parameter of optical bistability, and analogous to the scaled Rabbi frequency for driven systems where the field is classical. Classes of steady states are iteratively constructed and expressions for the diffusion and friction coefficients at lowest order also derived. They have in most cases the same mathematical form as their free-space analog. The method offers a semiclassical explanation for two recent experiments of one atom trapping in a high Q cavity where the excited state is significantly saturated. Our results refute both claims of atom trapping by a quantized cavity mode, single or not. Finally, it is argued that the parameter newly constructed, as well as the groundwork of this method, are at least companions of the cooperativity parameter and its mother theory. In particular, we lay the stress on the apparently more fundamental role of our structure parameter.

TWO VOICES FROM SWEDEN: TRANSLATION IN THEORY AND PRACTICE (ANTTI, EKMAN)
Creators: name: Fallenius, Charlotte Diamantine C.
Publisher: name: American University
Year: 2023

description: Following translations of Gerda Antti's short story "Mother's Laughter" and four chapters of Kerstin Ekman's novel Darkness and Blueberry Bushes, this dissertation first discusses the problems of translation theory in general, then moves on to the specific difficulties of rendering Swedish literary prose into English. So far translation has stubbornly resisted theoretical regimentation. The central problem is that a word is much more than an arbitrary symbol; it accumulates through history a host of connotations. Thus, just as each language is embedded in the culture of its speaker, so each text is embedded in the history of that language. What the translator faces is the impossibility of reconciling two intricate linguistic networks of overlapping associations and symbols in which every unit is determined by at least two cultural contexts: the historical and the literary. In other words, just as there are no genuine synonyms within a single language, no word has an equivalent in another language. Until we know more about the relationship between semantics and phonology, the translator has to proceed without a theory. Nevertheless, from Dryden onwards, the overall orientation of translators has been divided into three: to "metaphrase" is to emphasize the structure of the original language, to "imitate" is to stress the structure of the target language. The majority of translators, however, "paraphrase," aiming for the best compromise between the demands of both languages. In the final analysis the translator's decisions are based on aesthetic considerations. After a discussion of general problems of modernizing, editing, and the question of how to deal with dialects, slang, etc., the difficulties of translating from Swedish to English are considered in terms of overall culturalization of the text, dialect and slang, and the need to capture in the target language the original "voice" of the author. In reference to this "voice," the differences between Swedish and English word order, genitive constructions, and use of compound words are investigated. Finally, the guiding principle for dealing with all these problems is substitution. Instead of attempting to reproduce, the translator should find a way to suggest a "voice," a dialect, or a culture.

description: We develop a new method to compute the exact overlaps between integrable boundary states and on-shell Bethe states for integrable spin chains. Our method is based on the coordinate Bethe Ansatz and does not rely on the "rotation trick" of the corresponding lattice model. It leads to a rigorous proof of the factorized overlap formulas in a number of cases, some of which were inaccessible to earlier methods. As concrete examples, we consider the compact XXX and XXZ Heisenberg spin chains, and the non-compact $SL(2,\mathbb{R})$ spin chain.

description: We consider further on the problem of the analogue Hawking radiation. We propose a fourth order ordinary differential equation, which allows to discuss the problem of Hawking radiation in analogue gravity in a unified way, encompassing fluids and dielectric media. In a suitable approximation, involving weak dispersive effects, WKB solutions are obtained far from the horizon (turning point), and furthermore an equation governing the behaviour near the horizon is derived, and a complete set of analytical solutions is obtained also near the horizon. The subluminal case of the original fluid model introduced by Corley and Jacobson, the case of dielectric media are discussed. We show that in this approximation scheme there is a mode which is not directly involved in the pair-creation process. Thermality is verified and a framework for calculating the grey-body factor is provided.

description: We use structural information from diffusion Monte Carlo calculations for two--dimensional 3He to calculate the effective mass. Static effective interactions are constructed from the density-- and spin structure functions using sumrules. We find that both spin-- and density-- fluctuations contribute about equally to the effective mass. Our results show, in agreement with recent experiments, a flattening of the single--particle self--energy with increasing density, which eventually leads to a divergent effective mass.

description: Asymmetric time series models, as introduced by William Wecker (1981), vary according to whether previous random shocks, or innovations, of the time series are positive or negative; and have been shown to be useful in modeling industrial price quotations. Identifying when a particular time series exhibits this asymmetric structure is the subject of this work. We have derived a new statistic, based on a standardized time series correlation,; (DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI). where. (DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI). which is demonstrated to be powerful in distinguishing between asymmetric and symmetric time series and is easier to compute them than the likelihood ratio test used by Wecker. A multivariate statistic based on several forms of this statistic, Z(,ij)(k), is shown to have greater power in distinguishing asymmetric and symmetric time series. Several forms of the statistic, Z(,ij)(k), are proven to be asymptotically normally distributed, and our data suggest that they are approximately distributed as N(0,1) in smaller samples, under the null hypothesis of symmetry. As well as identifying whether or not a time series is asymmetric, the new statistic can be use to estimate the parameters of the asymmetric model. Finally, it is shown that asymmetric times series can be used to model some well known sunspot data.

description: Research background: Strengthening agriculture and food systems have a critical role to play in achieving the sustainable development goals of eliminating hunger and poverty; and increasing resilience to climatic shocks. Crop diversification has been recognized as a way of increasing resilience and reducing agricultural risk. Closing the gender gap could boost agricultural productivity and enhance welfare. Effects of crop diversification in enhancing dietary diversity amidst gender gap in agricultural productivity among smallholders have not been well established in Nigeria. Purpose of the article: The study was conducted to provide empirical evidence on crop diversification, productivity and dietary diversity of male and female-headed farming households in Nigeria. This has policy implications on development of inclusive and efficient agrifood system towards achieving the SDGs of eradicating poverty, hunger and gender equality. Methods: Secondary data from the 2015/16 Living Standard Measurement Survey-Integrated Survey on Agriculture (LSMS-ISA) was used for this study. Tobit regression model was employed to investigate the factors influencing crop diversification and dietary diversity while Oaxaca-Blinder decomposition method was used to decompose gender differentials in agricultural productivity. Findings and value added: Crop diversification index of male farmers is 0.10 (P<0.05) higher than female farmers. The Tobit regression results showed that farm income, education, household size, farm size and use of inorganic fertilizer increased crop diversification (P< 0.01). However, household expenditure (p< 0.05), non-farm income (p< 0.1), age and credit access (P< 0.01) reduced crop diversification. Less than half (45.22%) of the rural households consumed at least nine out of the 12 food groups in the previous week of the survey period. Crop diversification among other factors has a positive (P<0.01) effect on households’ dietary diversity. The results of the Oaxaca-Blinder decomposition showed a gender productivity gap of 10.87% in favour of male farmers. The structural and endowment disadvantages of female farmers in land size and credit access are key drivers of gender differentials in agricultural productivity. The study suggests improvement in land tenure system and female farmers’ access to financial services in order to ensure gender productivity equality, women empowerment and efficient agrifood system.

description: Bose-condensation of mass-less quasiparticles (photons) can be easily achieved at the room temperature in lasers. On the other hand, condensation of bosons having a non-zero mass requires usually ultra-low temperatures. Recently, it has been shown that polaritons, which are half-light-half-matter quasi-particles, may form condensed states at high temperatures (up to 300K). Polaritons composed by electron-hole pairs coupled to confined light modes in optical cavities may form a Bardeen-Cooper-Schriefer (BCS) superfluid. We propose a new transistor based on stimulated scattering of electron-hole pairs into the BCS polariton mode. A pn-junction embedded inside an optical cavity resonantly emits light into the cavity mode. If the cavity mode energy slightly exceeds the band-gap energy, it couples with electron-hole pairs with zero centre of mass wave-vector but non-zero wave-vector of relative motion. This creates a super-current in the plane of the structure. In an isotropic case, its direction is chosen by the system spontaneously. Otherwise, it is pinned to the external in-plane bias. We calculate the phase diagram for the electron-hole-polariton system.

AN ANALYSIS OF TYPOGRAPHIC FACTORS ON THE VISUAL INFORMATION PROCESSING OF DISABLED READERS
Creators: name: Canary, Mary Ryan
Publisher: name: American University
Year: 2023

description: This investigation utilized an experimental design to probe the relationship between the typographical design of the printed page and the initial stage of recognition in the visual processing of disabled readers. The independent variables included: (1) the typeface width--standard, condensed, and extended; (2) print weight--regular and medium bold; and (3) two variations of leading--one-and two-point. Letter height was held constant by using the same typeface (Geneva, sans serif, 11-point). Also held constant was area illumination (2150(DEGREES)K). The dependent variable was the number of correct responses made by sixty disabled readers on a three-hundred word tracking exercise that was assembled in composition form but contained no meaningful sentences. This approach enabled subjects to read for word recognition rather than comprehensive meaning, enhancing the possibility that the subjects would be using an initial stage of visual information processing. Each of twelve printed selections contained a combination of the three independent variables. Five subjects were randomly assigned to each of the twelve forms. Each student read one form. The exercise was interspersed with the target word "pac-man," twenty times. Subjects who were of average intelligence and reading two or more years below grade level completed the exercises individually, identifying and underlining the target words in a one-minute time limit. Scores were tallied by counting the number of correctly underlined target words. These scores provided the raw data. The relationship between print characteristics and disabled readers was treated statistically by a three-way analysis of variance. The results of this experiment led to the conclusion that extended letter width was significantly less legible (p < .05) than the standard or condensed widths across the two print weights and the two variations in leading. The major contribution of the study is the implication that specific features of typography can influence the effectiveness of the reading process for the disabled reader.

description: Students from CIVL 498C course conducted a Life Cycle Assessment study on the academic buildings on the UBC Vancouver Campus. This study determined the environmental impacts from material use and construction of the buildings, which gave an opportunity for students to understand the changes needed to minimize the life cycle impacts of constructing buildings at UBC. To conduct the study and accompanied analysis, students used the Athena Environmental Impact Estimator tool. Results from the study determined that in order to institutionalize LCA studies at UBC Vancouver Campus, guidelines and standards similar to those used in the course’s LCA study must be set by the Campus and Community Planning Green Building Division. The LCA studies should also be marketed to encourage a healthy dialogue between stakeholders who will potentially request these studies.

description: We take into account two further physical models which play an utmost importance in the framework of Analogue Gravity. We first consider Bose--Einstein condensates (BEC) and then surface gravity waves in water. Our approach is based on the use of the master equation we introduced in a previous work. A more complete analysis of the singular perturbation problem involved, with particular reference to the behavior in the neighbourhood of the (real) turning point and its connection with the WKB approximation, allows us to verify the thermal character of the particle production process. Furthermore, we can provide a simple scheme apt to calculate explicitly the greybody factors in the case of BEC and surface waves. This corroborates the improved approach we proposed for studying the analogue Hawking effect in the usual limit of small dispersive effects.

This molecule also contains glutamic acid, glycine, proline, aspartic acid, valine, phenylalanine and arginine. The reaction of cyanogen bromide with the lysinoalanine residue in cinnamycin leads to the formation of a new amino acid which elutes in the aliphatic region of the amino acid analyzer. The aspartic and glutamic acid residues were found to be present in the amide forms and the -COOH terminus was found to be lysinoalanine by esterification and reduction. Some of the possible structures for cinnamycin are discussed. A new peptide, larger than cinnamycin was isolated and found to have an amino terminus of isoleucine (by dinitrophenylation). The synthesis of (alpha), (alpha)-diacetaminopropionic acid was successfully performed by using aqueous sulfuric acid in place of concentrated sulfuric acid. High Performance Liquid Chromatographic (HPLC) techniques for purification and analysis of cinnamycin and its degradation products have been developed. Separations of derivatized amino acids were also developed and utilized. Ion pair HPLC was used in the development of a separation of free amino acids.

Microlensing by the Halo MACHOs with Spatially Varying Mass Function

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The main aim of microlensing experiments is to evaluate the mean mass of massive compact halo objects (MACHOs) and the mass fraction of the Galactic halo made by this type of dark matter. Statistical analysis shows that by considering a Dirac-Delta mass function (MF) for the MACHOs, their mean mass is about that of a white dwarf star. This result is, however, in discrepancy with other observations such as those of non-observed expected white dwarfs in the Galactic halo which give rise to metal abundance, polluting the interstellar medium by their evolution. Here we use the hypothesis of the spatially varying MF of MACHOs, proposed by Kerins and Evans to interpret microlensing events. In this model, massive lenses with a lower population contribute to the microlensing events more frequently than do dominant brown dwarfs. This effect causes the mean mass of the observed lenses to be larger than the mean mass of all the lenses. A likelihood analysis is performed to find the best parameters of the spatially varying MF that are compatible with the duration distribution of Large Magellanic Cloud microlensing candidates of the MACHO experiment.

description: Asymmetric mono-carboxy-porphyrins, (5-(4-carboxyphenyl)−10,15,20-tris(pentafluorophenyl)porphyrinato zinc(II) (1), 5-(4-carboxyphenyl)−10,15,20-triphenylporphyrinato zinc(II) (2) and 5-(4-carboxyphenyl)−10,15,20-tris(2-thienyl)porphyrinato zinc(II) (3), were linked to Ag nanoparticles (AgNPs) through amide bonds and self-assembly (the latter only for 3). The porphyrins and conjugates were used for photodynamic antimicrobial chemotherapy (PACT) against Staphylococcus aureus. PACT uses singlet oxygen for antimicrobial activity. Complex 3 and its conjugates had higher singlet oxygen quantum yields and higher log reduction when compared with the rest of the porphyrins and corresponding conjugates. These high log reductions for 3 and its conjugate were attributed to the presence of sulfur groups whereby there was more interaction with the bacterial membrane.
A COMPARATIVE STUDY OF SAMPLES OF MALE AND FEMALE HEARING AND HEARING-IMPAIRED COLLEGE FRESHMEN ALONG SELECTED DEVELOPMENTAL DIMENSIONS
Creators: name: Turk, Frank Robert
Publisher: name: American University
Year: 2023

description: The purpose of the study was to compare the developmental profiles of samples of male and female hearing and hearing-impaired college freshmen along three developmental dimensions, namely developing autonomy, developing purpose and developing mature interpersonal relationships, as assessed through the Student Developmental Task Inventory, Second Edition (SDTI-2), and to interpret the findings for their utility in identifying student personal developmental needs which can be addressed through student affairs programming. The study was based on hypotheses that there was no difference between samples of male and female hearing and hearing-impaired college freshmen for each of three developmental tasks, developing autonomy, developing purpose, and developing mature interpersonal relationships, as assessed through the SDTI-2. It was also hypothesized that there was an interaction between hearing ability and sex regarding these samples and tasks. Nine operational hypotheses were tested. The study population consisted of 72 hearing and hearing-impaired college freshmen at The American University (36) and Gallaudet College (36). The SDTI-2 was used to assess student growth and development along three developmental dimensions. The Personal Data Profile (PDP) elicited six items of descriptive or census data. The data were computed by an IBM 370 Computer, using the Statistical Package for the Social Sciences program. Student's t-test and a two-way analysis of variance, utilizing a randomized fixed effects model, were used in hypotheses testing. The .05 level was set as the standard for statistical significance. Eight of the nine operational hypotheses were not confirmed. The study samples of hearing versus hearing-impaired college freshmen did not differ to the extent of statistical significance regarding each developmental area, developing autonomy, developing purpose, and developing mature interpersonal relationships. Five of the six hypotheses postulating differences between male and female, hearing and hearing-impaired study subjects regarding these same developmental areas were not confirmed. Hearing-impaired females were found to be significantly ahead of hearing-impaired males in developing autonomy whereas the reverse was true for hearing males and hearing females. Study findings supported the conclusion that deaf college students are not handicapped by their deafness in achieving the developmental tasks of reference.

CHANGING MODES OF RATIONALITY IN THE EARLY EVOLUTION OF MODERN ECONOMIC THOUGHT

description: Reversing the commonly accepted view, some historians of economic thought have dated the origins of modern economic thought in the breakdown of feudal society. But these writers have not produced fully convincing ways of relating changes in socio-economic reality to corresponding alternatives in medieval economic doctrine. The present study attempts to remedy this theoretical weakness with the thesis that during the twelfth and thirteenth centuries a substantive change began occurring in the mode of rationality by which the social world of medieval Europe was legitimated. This change involved a transformation in the manner of reasoning by which economic practice was explained and justified, encompassing developments in socio-economic conditions as well as in the evolution of doctrine. Before the change began to occur, the predominant mode of rationality, expressed in the social doctrine of Church Fathers as well as in civil law, was oriented by an interest in agreeing on morally appropriate conduct according to the principle of social ranking by status. Gradually, however, as new commercial practices began multiplying, the predominant model of reasoning became more similar to what we now call scientific rationality. Economic practices began to be oriented more by interest in finding the most efficient way of behaving. Thus the process of modernization commenced its long advance. The present study examines how scholastic writers extended the scope of modern rationality when they extended the Romanist and canonist modifications of traditional anti-commercialist doctrine to all cases of market exchange. Under thirteenth-century socio-economic conditions this development involved a reinterpretation of value in which the principles of market exchange were dissociated from those of distribution. Changing modes of rationality are evident both in the scholastic approach to the measurement of value and in the corresponding explanation of producer interests. Scholastic just-price doctrine disrupted the unified explanation of feudal society by extending technical rationality in the domain of exchange while retaining practical rationality in the realm of distribution. This study complements the work of those who go beyond conventional and neoclassical attempts to explain this inconsistency in scholastic economic thought.
