description: We apply the functional renormalization group method to the calculation of dynamical properties of zero-dimensional interacting quantum systems. As case studies we discuss the anharmonic oscillator and the single impurity Anderson model. We truncate the hierarchy of flow equations such that the results are at least correct up to second order perturbation theory in the coupling. For the anharmonic oscillator energies and spectra obtained within two different functional renormalization group schemes are compared to numerically exact results, perturbation theory, and the mean field approximation. Even at large coupling the results obtained using the functional renormalization group agree quite well with the numerical exact solution. The better of the two schemes is used to calculate spectra of the single impurity Anderson model, which then are compared to the results of perturbation theory and the numerical renormalization group. For small to intermediate couplings the functional renormalization group gives results which are close to the ones obtained using the very accurate numerical renormalization group method. In particulare the low-energy scale (Kondo temperature) extracted from the functional renormalization group results shows the expected behavior.

description: The objective of this study was to determine the possible occurrence of aflatoxicol (R(,0)) as a residue in edible animal tissue and its relation to aflatoxins B(,1) (B(,1)) and M(,1) (M(,1)). Towards this end two analytical methods were developed, one for R(,0) in milk, blood, and tissue, and one for R(,0) in eggs and ova. These methods were also adapted to determine B(,1) and M(,1) in the same extract. The methods utilized a fluorescence detector of a high performance liquid chromatographic system to measure R(,0) and a Fluorodensitometer after thin layer chromatographic separation to quantitate B(,1) and M(,1). Five animal studies were conducted: (1) 2 lactating cows were each given B(,1) as a single oral dose of 0.5 mg/kg bw, (2) 6 lactating cows were each given B(,1) either orally or abomasally for five days at a daily dose of 0.15 mg/kg bw, (3) 3 pigs were each given B(,1) as a single oral dose of 1.0 mg/kg bw, (4) 20 pigs were given for 14 days a feed naturally contaminated with B(,1) at a level of 400 (mu)g/kg, and (5) 18 laying hens were given for 7 days a ration containing B(,1) at a level of 8.0 mg/kg. The milk, blood, muscle, organs, or eggs collected at selected time intervals from the dosed animals were analyzed for R(,0), B(,1) and M(,1). R(,0) was found in milk (0.01 - 1.3 ng/g), cow blood (0.01 - 0.31 ng/g), pig tissues (0.01 - 4.5 ng/g), chicken tissues (0.03 - 0.62 ng/g) and eggs (0.02 - 0.33 ng/g). In milk and blood the B(,1) metabolite, M(,1), was the major residue observed, followed by the parent compound B(,1) and then R(,0). The levels of M(,1) and B(,1) were about 10 times higher in milk than in blood from the same animal. The levels of R(,0) were similar in milk and cow blood, were at least 200 times less than M(,1) levels and were at least 10 times less than B(,1) levels. In pig tissues the levels of M(,1) and B(,1) were about the same and were about 20 times greater than the levels of R(,0). In eggs the levels of B(,1) and R(,0) were about the same; no M(,1) was found. In chicken tissues the B(,1) levels were about twice as high as R(,0) levels; M(,1) was found only in the kidneys.

description: Deep neural networks (DNNs) are successful in many computer vision tasks. However, the most accurate DNNs require millions of parameters and operations, making them energy, computation and memory intensive. This impedes the deployment of large DNNs in low-power devices with limited compute resources. Recent research improves DNN models by reducing the memory requirement, energy consumption, and number of operations without significantly decreasing the accuracy. This paper surveys the progress of low-power deep learning and computer vision, specifically in regards to inference, and discusses the methods for compacting and accelerating DNN models. The techniques can be divided into four major categories: (1) parameter quantization and pruning, (2) compressed convolutional filters and matrix factorization, (3) network architecture search, and (4) knowledge distillation. We analyze the accuracy, advantages, disadvantages, and potential solutions to the problems with the techniques in each category. We also discuss new evaluation metrics as a guideline for future research.

Publisher: name: American University
Year: 2023

description: The purposes of this study were to assess the perceptions and knowledge of environmental issues possessed by science and non-science educators in Nigeria and to determine whether any relationships and differences existed in their perceptions and knowledge of environmental issues. Selected inventory items on environmental issues were validated by a jury of experienced educators from Nigerian and American universities, and tested in a pilot study. The devised inventory was administered to a sample population of (1) 21 college science educators, (2) 30 science-oriented teacher trainees, and (3) 45 non-science-oriented teacher trainees from two institutions of higher education in Imo State of Nigeria. A total return rate of 77 percent was achieved. Responses were assigned codes and subjected to the Spearman's correlation coefficient and the Mann-Whitney U tests which were used to determine significant relationships and differences between groups in the sample population. The alpha at 0.05 level of significance with no direction predicted was used to evaluate each test. Analyses of the responses from the sample population showed that: (1) there was no significant correlation between perceptions and knowledge of environmental issues possessed by college science educators and science-oriented teacher trainees; (2) there was a significant correlation between the perceptions and knowledge of environmental issues possessed by non-science-oriented teacher trainees; (3) no significant differences were found to exist in the perceptions of environmental issues possessed by the science and non-science groups; and (4) no significant differences were found to exist in the knowledge of environmental issues possessed by the science and non-science groups. Conclusions drawn from the study were: (1) that perceptions of environmental issues among educators who were academically oriented towards science did not depend on their knowledge of environmental issues; (2) that among educators who were not academically oriented towards science, perceptions of environmental issues were related to their knowledge of environmental issues; and (3) that educators responding to the survey generally possessed favorable perceptions and moderate knowledge of environmental issues. It is, however, possible that other factors, which were not covered by this study, played an important part in the educators' perceptions and knowledge of environmental issues.

description: In a fundamental test of quantum mechanics, we have observed 228~000 quantum jumps of a single trapped and laser cooled $^{88}$Sr$^+$ ion. This represents a statistical increase of two orders of magnitude over previous similar analyses of quantum jumps. Compared to other searches for non-randomness in quantum mechanical processes, using quantum jumps simplifies the interpretation of data by eliminated multi-particle effects and providing near-unit detection efficiency of transitions. We measure the fractional reduction in the entropy of information to be $< 6.5~10^{-4}$ when the value of any interval between quantum jumps is known. We also find that the number of runs of successively increasing or decreasing interval times agrees with the theoretically expected values. Furthermore, we analyze 238~000 quantum jumps from two simultaneously confined ions and find that the number of apparently coincidental transitions is as expected. Finally, we observe 8400 spontaneous decays of two simultaneously trapped ions and find that the number of apparently coincidental decays from the metastable state agrees with the expected value. We find no evidence for short- or long-term correlations in the intervals of the quantum jumps or in the decay of the quantum states, in agreement with quantum theory.

description: We address the intervention of classical-like behavior, well documented in experimental studies of strongly correlated electron systems of solids that emerges at temperatures $T$ far below the Debye temperature $T_D$. We attribute this unexpected phenomenon to spontaneous rearrangement of the conventional Landau state beyond a critical point at which the topological stability of this state breaks down, leading to the formation of an interaction-induced flat band adjacent to the nominal Fermi surface. We demonstrate that beyond the critical point, the quasiparticle picture of such correlated Fermi systems still holds, since the damping of single-particle excitations remains small compared with the Fermi energy $T_F=p^2_F/2m_e$. A Pitaevskii-style equation for determination of the rearranged quasiparticle momentum distribution $n_*({\bf p})$ is derived, which applies to explanation of the linear-in-$T$ behavior of the resistivity $ρ(T)$ found experimentally.

description: The strong coupling of a superconductor to a spinful quantum dot results in Yu-Shiba-Rusinov (YSR) discrete subgap excitations. In isolation and at zero temperature, the excitations are $δ$ resonances. In transport experiments, however, they show as broad differential conductance peaks. We obtain the lineshape of the peaks and their temperature dependence in superconductor-quantum-dot-metal (S-QD-N) nanowire-based devices. Unexpectedly, we find that the peaks shift in energy with temperature, with the shift magnitude and sign depending on ground state parity and bias voltage. Additionally, we empirically find a power-law scaling of the peak area versus temperature. These observations are not explained by current models.

description: Idiopathic pulmonary fibrosis (IPF) is a devastating chronic lung disease characterised by fibrosis and scarring of lung tissue. Current approved therapeutics having limited efficacy and severe adverse effects. This thesis investigates the activation of the prostacyclin receptor (IPR), as a potential therapeutic approach for the treatment of IPF. Using targeted FRET biosensors to investigate cAMP and ERK signalling with high spatial and temporal resolution, a complex relationship was discovered between IPR signalling and phenotypic outcome The most significant result was the reversal of efficacy at phenotypically relevant readouts, demonstrating that sustained cAMP signalling may be important for IPF therapeutics.

description: In this article, we describe twopm, a command for fitting two-part models for mixed discrete-continuous outcomes. In the two-part model, a binary choice model is fit for the probability of observing a positive-versus-zero outcome. Then, conditional on a positive outcome, an appropriate regression model is fit for the positive outcome. The twopm command allows the user to leverage the capabilities of predict and margins to calculate predictions and marginal effects and their standard errors from the combined first- and second-part models.

description: Spectral energy distribution (SED) analyses, that include new millimeter (mm) to far-infrared (FIR) observations, obtained with continuum instruments on the Nobeyama and James Clerk Maxwell Telescopes and Infrared Space Observatory (ISO), are presented for seven, nearby (< 45Mpc) FIR-bright elliptical galaxies. These are analyzed together with archival FIR and short-wave radio data obtained from the NASA/IPAC Extragalactic Database (NED). The radio to infrared SEDs are best fit by power-law plus greybody models of dust residing in the central galactic regions within 2.4kpc diameter and with temperatures between about 21 and 28K, emissivity index approximately 2, and masses from about 0.16 to 1.9 million solar masses. The emissivity index is consistent with dust constituting amorphous silicate and carbonaceous grains previously modeled for stellar-heated dust observed in the Galaxy and other nearby extragalactic sources. Using updated dust absorption coefficients for this type of dust, dust masses are estimated that are similar to those determined from earlier FIR data alone, even though the latter results implied hotter dust temperatures. Fluxes and masses that are consistent with the new FIR and submm data are estimated for dust cooler than 20K within the central galactic regions. Tighter physical constraints for such cold, diffuse dust (if it exists) with low surface brightness, will need sensitive FIR-submm observations with the Spitzer Space Telescope, SCUBA2, or ALMA.

description: We present the clrbound, clr2bound, clr3bound, and clrtest commands for estimation and inference on intersection bounds as developed by Chernozhukov, Lee, and Rosen (2013, Econometrica 81: 667–737). The intersection bounds framework encompasses situations where a population parameter of interest is partially identified by a collection of consistently estimable upper and lower bounds. The identified set for the parameter is the intersection of regions defined by this collection of bounds. More generally, the methodology can be applied to settings where an estimable function of a vector-valued parameter is bounded from above and below, as is the case when the identified set is characterized by conditional moment inequalities. The commands clrbound, clr2bound, and clr3bound provide bound estimates that can be used directly for estimation or to construct asymptotically valid confidence sets. clrtest performs an intersection bound test of the hypothesis that a collection of lower intersection bounds is no greater than zero. The command clrbound provides bound estimates for one-sided lower or upper intersection bounds on a parameter, while clr2bound and clr3bound provide two-sided bound estimates using both lower and upper intersection bounds. clr2bound uses Bonferroni’s inequality to construct two-sided bounds that can be used to perform asymptotically valid inference on the identified set or the parameter of interest, whereas clr3bound provides a generally tighter confidence interval for the parameter by inverting the hypothesis test performed by clrtest. More broadly, inversion of this test can also be used to construct confidence sets based on conditional moment inequalities as described in Chernozhukov, Lee, and Rosen (2013). The commands include parametric, series, and local linear estimation procedures.

description: The purpose of this paper is to articulate a coherent and easy-to-understand way of doing quantum mechanics in any finite-dimensional Liouville space, based on the use of Kronecker product and what we have termed the `bra-flipper' operator. One of the greater strengths of the formalism expatiated on here is the striking similarities it bears with Dirac's bra-ket notation. For the purpose of illustrating how the formalism can be effectively employed, we use it to solve a quantum optical master equation for a two-level quantum system and find its Kraus operator sum representation. The paper is addressed to students and researchers with some basic knowledge of linear algebra who want to acquire a deeper understanding of the Liouville space formalism. The concepts are conveyed so as to make the application of the formalism to more complex problems in quantum physics straightforward and unencumbered.

INTENTIONALITY: AN INQUIRY INTO MIKEL DUFRENNE'S PHENOMENOLOGY OF AESTHETICS
Creators: name: Whitman, Joan Catherine
Publisher: name: American University
Year: 2023

description: The topic of this Dissertation is Mikel Dufrenne's Phenomenology of Aesthetics. In particular, it will focus on Dufrenne's claim that art is intersubjective, and will necessarily entail an inquiry into the basic components of phenomenology and aesthetics which influenced Dufrenne. This study will be divided into five component parts. Chapter One offers a brief investigation into the historical background of phenomenological and aesthetic theories relevant to Dufrenne's thesis. It will provide the reader with a basic understanding of the theories which encouraged Dufrenne to postulate his provocative claim that art is a phenomenological event. The notion of intentionality as regards Dufrenne will be the focus of Chapter Two. It particularly will establish Dufrenne's epistemological foundation of phenomenology in terms of three of his major works: The Notion of the A Priori, The Phenomenology of Aesthetic Experience, and Main Trends in Aesthetics and the Sciences of Art. Herein, Dufrenne's claim that the world is intersubjective due to the primordial rootedness of the a priori will be presented in the light of his aesthetic theory. Chapter Three will serve as an analysis of the positions stated in Chapter Two. It will evaluate and summarize Dufrenne's positions insofar as he has systematically presented them to the reader, in support of his final claims regarding the nature of contemporary art. The focus of Chapter Four will be those criticisms of Dufrenne's theory which have been presented to Dufrenne as well as extended criticisms offered by the author. It will evaluate those criticisms in terms of their own significance and with respect to a general phenomenology of aesthetics. Chapter Five will offer a summary of Dufrenne's position and the criticisms which have been made regarding it. It will also discuss some possible consequences for a phenomenology of art, particularly with respect to contemporary art. This Dissertation serves as a unique analysis of Mikel Dufrenne's Phenomenology of Aesthetics. It intends to evaluate his position in the light of its consistency, epistemology and final contentions. Through this study, aesthetic theory will be presented a new and perhaps revolutionary theory in keeping with the position of art in modern society.

We compare the obtainable sensitivities to predictions from neutrino mass models and to the size of quantum corrections. We find that the theoretical expectations for deviations are typically well within experimental reach.

description: Maxima is a free and open-source computer algebra system that can perform symbolic computations such as solving equations, determining derivatives of functions, obtaining Taylor series, and manipulating algebraic expressions. In this article, I present the Maxima Bridge System, which is a collection of software programs that allows Stata to interface with Maxima so that Maxima can be used for symbolic computation to transfer data from Stata to Maxima and to retrieve results from Maxima. The cooperation between Stata and Maxima provides an environment for statistical analysis in which symbolic computation can be easily used together with all the facilities supplied by Stata. In this environment, symbolic computation algorithms can be used to manage the complexity of algebra and calculus, whereas numerical computation can be used when speed matters. I also discuss the software architecture of the Maxima Bridge System, and I present several examples to illustrate how to develop new Stata commands that exploit the capabilities of Maxima.

description: By using supermanifold techniques we prove a generalization of the localization formula in equivariant cohomology which is suitable for studying supersymmetric Yang-Mills theories in terms of ADHM data. With these techniques one can compute the reduced partition functions of topological super Yang-Mills theory with 4, 8 or 16 supercharges. More generally, the superlocalization formula can be applied to any topological field theory in any number of dimensions.

description: The topic of this Dissertation is Mikel Dufrenne's Phenomenology of Aesthetics. In particular, it will focus on Dufrenne's claim that art is intersubjective, and will necessarily entail an inquiry into the basic components of phenomenology and aesthetics which influenced Dufrenne. This study will be divided into five component parts. Chapter One offers a brief investigation into the historical background of phenomenological and aesthetic theories relevant to Dufrenne's thesis. It will provide the reader with a basic understanding of the theories which encouraged Dufrenne to postulate his provocative claim that art is a phenomenological event. The notion of intentionality as regards Dufrenne will be the focus of Chapter Two. It particularly will establish Dufrenne's epistemological foundation of phenomenology in terms of three of his major works: The Notion of the A Priori, The Phenomenology of Aesthetic Experience, and Main Trends in Aesthetics and the Sciences of Art. Herein, Dufrenne's claim that the world is intersubjective due to the primordial rootedness of the a priori will be presented in the light of his aesthetic theory. Chapter Three will serve as an analysis of the positions stated in Chapter Two. It will evaluate and summarize Dufrenne's positions insofar as he has systematically presented them to the reader, in support of his final claims regarding the nature of contemporary art. The focus of Chapter Four will be those criticisms of Dufrenne's theory which have been presented to Dufrenne as well as extended criticisms offered by the author. It will evaluate those criticisms in terms of their own significance and with respect to a general phenomenology of aesthetics. Chapter Five will offer a summary of Dufrenne's position and the criticisms which have been made regarding it. It will also discuss some possible consequences for a phenomenology of art, particularly with respect to contemporary art. This Dissertation serves as a unique analysis of Mikel Dufrenne's Phenomenology of Aesthetics. It intends to evaluate his position in the light of its consistency, epistemology and final contentions. Through this study, aesthetic theory will be presented a new and perhaps revolutionary theory in keeping with the position of art in modern society.

description: Electrical magnetoresistance and tunnel diode oscillator measurements were performed under external magnetic fields up to 41 T applied along the crystallographic b-axis (hard axis) of UTe$_2$ as a function of temperature and applied pressures up to 18.8 kbar. In this work, we track the field-induced first-order transition between superconducting and magnetic field-polarized phases as a function of applied pressure, showing a suppression of the transition with increasing pressure until the demise of superconductivity near 16 kbar and the appearance of a pressure-induced ferromagnetic-like ground state that is distinct from the field-polarized phase and stable at zero field. Together with evidence for the evolution of a second superconducting phase and its upper critical field with pressure, we examine the confinement of superconductivity by two orthogonal magnetic phases and the implications for understanding the boundaries of triplet superconductivity.

description: The dissertation focuses upon the religious rituals, social forms, and adaptive strategies which the Zulu Zionists of South Africa use to treat illnesses. Four problem orientations guided the study: (1) to account for the sources of the fluidity of Zulu Zionism; (2) to determine the conceptualization of power and its multiple expressions in Zulu Zionism; (3) the categorization of physical and mental illnesses; (4) the recasting of historically defined Zulu healing roles within Zionism. Research has been guided by the hypothesis that Zulu Zionists, in their approaches to illness and healing, are highly syncretistic and generate new concepts for the causes and cures of illness and in turn restructure social roles to accommodate these concepts. The research was carried out through the methods of participant-observation of Zionist services, extended interviews with leaders, congregants, and patients and through the use of videotapes during eleven months of field research in Durban, and its rural Zulu hinterland. Quantitative methods included the construction of a data matrix for forty Zionist services and twenty-four Zionist practitioners, and the subjection of the cases and appropriate variables to frequency distribution and factor analyses. A central finding of the study is that in their diagnoses and treatment of illnesses the Zionists regard the unity of the group and its health as important as the apparent features of a patient's physical or psychological symptoms. Zionists have also perfected ways for symbolizing "power" through their uses of color and ritual, and have successfully demonstrated ways of converting spiritual power to social uses which extend beyond the realm of religious services. It was also found that Zionists link their conceptualization and treatment of mental illnesses to various types of spirit possession that have been historically recognized in Zulu society. The study concludes that the viability and adaptability of Zulu Zionism is a holistic medical system that fulfills the social, psychological, and religious needs of its members.
Quantum Hall Criticality, Superconductor-Insulator Transition and Quantum Percolation

description: A model consisting of a mixture of superconducting and quantum links is proposed to describe the integer quantum Hall transition. The quantum links correspond to tunneling of electrons between trajectories trapped in adjacent potential valleys, while the superconducting links correspond to merging of these trajectories once the Fermi energy crosses the saddle point energy separating the two valleys. The quantum Hall transition in this model corresponds to percolation of the superconducting links. Numerical calculations and scaling analysis using two different approaches yield the critical exponent $ν\approx 2.4$ and a two-peak conductance distribution at the critical point. The role of quantum coherence is discussed, and an explanation of experimental observations claiming different universality class for the quantum Hall transition is suggested. The model suggests that the critical behavior of the superconductor-insulator transition from the insulating side is in the same universality class as the quantum Hall transition.

DEAFNESS, COMMUNICATION, AND SOCIAL IDENTITY: AN ANTHROPOLOGICAL ANALYSIS OF INTERACTION AMONG PARENTS, TEACHERS, AND DEAF CHILDREN IN A PRESCHOOL

description: This study uses data derived from participant-observation in a preschool for deaf children, in-depth interviews of Deaf and hearing parents and a hearing teacher, and videotaped interaction between adults and preschool deaf children to investigate the complex relationships among expressed language attitudes, communication behavior, and social identity when deafness is a variable. It systematically documents parents' and educators' expressed attitudes about language and deafness together with the observed communication behavior of eight of these adults with three preschool deaf children. Socio-political variables operating within the school are identified and social processes and symbols analyzed when the Deaf parents form a special interest group. Analysis suggest that variables related to the socio-political context, the individual social actor, and the interactional spheres in which those actors participate combine in complex ways to give shape to the social life within the school. Deaf people who recognize themselves as socially and culturally Deaf and use sign language constitute a social group similar to an ethnic group. Establishing a basic social identity with respect to membership in such a Deaf group is a complex process for deaf children, however, since parents and teachers are usually not deaf but have normal hearing. Schools for deaf children are complex linguistic and social environments with interaction among parents, teachers and children shaped, in part, by tensions between two competing social identities, "Deaf" and "hearing," which are symbolized, in part, by two competing languages, American Sign Language (ASL) and manually encoded English (MCE). Analysis of the videotapes focused on the use of targeted features of MCE and ASL by the participants. The adults and children differed in theoretically important ways with respect to their linguistic experiences, skills, and preferences; however, analysis showed that all of the participants used code-mixing in their communication. Data from the videotapes, interviews, and participant-observation together suggest how an individual's choice of language and his or her expressed language attitudes serve to indicate, construct, and maintain Deaf or hearing social identity during social interaction with others. The resultant implications for parents, teachers, and schools are discussed.
