description: We present results from a set of high (512^3 effective resolution), and ultra-high (1024^3) SPH adiabatic cosmological simulations of cluster formation aimed at studying the internal structure of the intracluster medium (ICM). We derive a self-consistent analytical model of the structure of the intracluster medium (ICM). We discuss the radial structure and scaling relations expected from purely gravitational collapse, and show that the choice of a particular halo model can have important consequences on the interpretation of observational data. The validity of the approximations of hydrostatic equilibrium and a polytropic equation of state are checked against results of our simulations. The properties of the ICM are fully specified when a 'universal' profile is assumed for either the dark or the baryonic component. We also show the first results from an unprecedented large-scale simulation of 500 Mpc/h and 2 times 512^3 gas and dark matter particles. This experiment will make possible a detailed study of the large-scale distribution of clusters as a function of their X-ray properties.

description: We report a theoretical study on resonant x-ray emission spectra (RXES) in the whole energy region of the Mn $L_{2,3}$ white lines for three prototypical Mn/Ag(001) systems: (i) a Mn impurity in Ag, (ii) an adsorbed Mn monolayer on Ag, and (iii) a thick Mn film. The calculated RXES spectra depend strongly on the excitation energy. At $L_3$ excitation, the spectra of all three systems are dominated by the elastic peak. For excitation energies around $L_2$, and between $L_3$ and $L_2$, however, most of the spectral weight comes from inelastic x-ray scattering. The line shape of these inelastic ``satellite'' structures changes considerably between the three considered Mn/Ag systems, a fact that may be attributed to changes in the bonding nature of the Mn-$d$ orbitals. The system-dependence of the RXES spectrum is thus found to be much stronger than that of the corresponding absorption spectrum. Our results suggest that RXES in the Mn $L_{2,3}$ region may be used as a sensitive probe of the local environment of Mn atoms.

THE CONTRIBUTIONS OF ASSOCIATIVE AND NONASSOCIATIVE MECHANISMS IN THE US PREEXPOSURE EFFECT IN TASTE-AVERSION LEARNING
Creators: name: Dacanay, Robert Jereza
Publisher: name: American University
Year: 2023

description: In conditioned taste aversion learning, rats avoid the consumption of a taste solution that has previously been paired with a drug. When the drug is administered prior to the taste-drug pairing, however, subsequent taste-aversion learning is attenuated. This phenomenon has been called the US preexposure effect. Although this phenomenon is clear, its underlying mechanism is not. For example, depending upon the specific drug examined, either an associative or nonassociative mechanism has been presented to account for the effects of drug preexposure. To test whether the mechanism underlying the US preexposure effect is drug specific or simply a result of procedural differences in the examination of different drugs, rats in Experiment 1 were given five preexposures in a distinctive environment and conditioned either in the distinctive environment or the home cage to either LiCl (Experiment 1A) or morphine (Experiment 1B). As demonstrated, the drug-specific nature of the US preexposure was still evident with identical test procedures. It was suggested that the degree of pharmacological adaptation to the drug during preexposure might be responsible for this drug-specific nature of the preexposure effect. This view was supported in Experiment 2, in which a compound was given during preexposure to which pharmacological adaptation is slow to develop, i.e., methadone hydrochloride. It was predicted that with such a drug, both associative and nonassociative mechanisms may contribute to the preexposure effect simultaneously. As reported, both mechanisms contributed to the effects of methadone preexposure. If the degree of pharmacological change during preexposure determines the mechanism underlying the preexposure effect, it was suggested that the degree of pharmacological adaptation and the subsequent mechanism underlying the preexposure effect should be affected by the specific parameters used during preexposure. This possibility was tested and supported in Experiment 3, in which 10 methadone preexposures were administered. Under this condition, the mechanism underlying the methadone preexposure was totally nonassociative in nature. Based on these results, it was concluded that by knowing the degree of pharmacological adaptation and environmental conditioning during preexposure, the outcome of US preexposure within a taste aversion paradigm may be accounted for and predicted.

description: We discuss possible choices for boundary conditions in the AdS/CFT correspondence, and calculate the renormalisation group flow induced by a double-trace perturbation. In running from the UV to the IR there is a unit shift in the central charge. The discrepancy between our result and results obtained by other authors is accounted for by the discovery that there is a non-trivial flow for perturbations induced by bulk fields with masses saturating the Breitenlohner-Freedman bound.

description: We propose a new class of Proca interactions that enjoy a non-trivial constraint and hence propagates the correct number of degrees of freedom for a healthy massive spin-1 field. We show that the scattering amplitudes always differ from those of the Generalized Proca. This implies that the new class of interactions proposed here are genuinely different from the Generalized Proca and there can be no local field redefinitions between the two. In curved spacetime, massive gravity is the natural covariantization but we show how other classes of covariantizations can be considered.

description: The theory of Quantum Darwinism aims to explain how our objective classical reality arises from the quantum world, by analysing the distribution of information about a quantum system that is accessible to multiple observers, who probe the system by intercepting fragments of its environment. Previous work showed that, when the number of environmental fragments grows, the quantum channels modelling the information flow from system to observers become arbitrarily close - in terms of diamond norm distance - to "measure-and-prepare" channels, ensuring objectivity of observables; the convergence is formalised by an upper bound on the diamond norm distance, which decreases with increasing number of fragments. Here, we derive tighter diamond norm bounds on the emergence of objectivity of observables for quantum systems of infinite dimension, providing an approach which can bridge between the finite- and the infinite-dimensional cases. Furthermore, we probe the tightness of our bounds by considering a specific model of a system-environment dynamics given by a pure loss channel. Finally, we generalise to infinite dimensions a result obtained by Brandão et al. [Nat. Commun. 6, 7908 (2015)], which provides an operational characterisation of quantum discord in terms of one-sided redistribution of correlations to many parties. Our results provide a unifying framework to benchmark quantitatively the rise of objectivity in the quantum-to-classical transition.

Testing Quantum Dynamics using Signaling

description: We consider a physical system in which the description of states and measurements follow the usual quantum mechanical rules. We also assume that the dynamics is linear, but may not be fully quantum (i.e unitary). We show that in such a physical system, certain complementary evolutions, namely cloning and deleting operations that give a better fidelity than quantum mechanically allowed ones, in one (inaccessible) region, lead to signaling to a far-apart (accessible) region. To show such signaling, one requires certain two-party quantum correlated states shared between the two regions. Subsequent measurements are performed only in the accessible part to detect such phenomenon.

description: The water hydration shell has decisive impact on the structural and functional properties of RNA. Changes of RNA structure upon melting and in biochemical processes are accompanied by a change of hydration patterns, a process which is barely characterized. To discern hydration geometries around the backbone phosphate groups of an RNA double helix at the molecular level, we combine two-dimensional infrared spectroscopy of phosphate vibrations with theoretical simulations. There are three distinct coexisting hydration motifs of the RNA A-helix, an ordered chain-like arrangement of water molecules with links between neighboring phosphate groups, separate local hydration shells of up to six water molecules, and hydrated phosphate/counterion contact pairs. RNA disordering upon melting is connected with a transition from predominant ordered water structures to local hydration shells around phosphate units. Structural fluctuations are dominated by librational water motions occurring on a 300 fs time scale, without exchange between hydration motifs.
DEBT AND CRISIS IN LATIN AMERICA: THE SUPPLY SIDE OF THE STORY (EXTERNAL FINANCE, TRANSNATIONAL BANKS, DEVELOPMENT)
Creators: name: Devlin, Robert
Publisher: name: American University
Year: 2023

description: Debt in Latin America has received much attention since the outbreak of a major crisis beginning in mid-1982. When examining the causes of the crisis, analysts in the North have typically focused on deficiencies in the debtor countries' economic policy and or conjunctural shocks that were emitted from the world economy in the early 1980s. Very little attention has been given to the role of the region's principal creditors--private banks--in the development of the crisis. The study proposes to round out the story of Latin America's debt problem by demonstrating that the banks were an endogenous source of instability in Latin America's credit cycle, tending to overexpand on the upside and overcontract on the downside. The analysis draws much of its support from an institutional examination of modern transnational banking. The approach derives insights on bank behavior that often run counter to conventional wisdom, which is guided by more ahistorical portfolio theory. The analysis additionally provides some technical support to the frequent Latin American assertion of co-responsibility in the crisis. The study also examines potential solutions for the debt crisis. By employing a framework of bilateral monopoly, it shows that the debtor countries should not await the arrangement of multilateral public solutions because disproportionalities in creditor-debtor bargaining power create an inertia in the North that will make comprehensive multilateral initiatives at best slow in forthcoming. It is concluded that to relieve the excessive burden of the debt, Latin American governments must imaginatively explore unilateral solutions to the problem. To this end the study examines some nonconventional repayment strategies that might produce opportunities to unilaterally reduce payments without a high risk of retaliation by the banks and their governments.

description: We study a standard two-parameter family of area-preserving torus diffeomorphisms, known in theoretical physics as the kicked Harper model, by a combination of topological arguments and KAM-theory. We concentrate on the structure of the parameter sets where the rotation set has empty and non-empty interior, respectively, and describe their qualitative properties and scaling behaviour both for small and large parameters. This confirms numerical observations about the onset of diffusion in the physics literature. As a byproduct, we obtain the continuity of the rotation set within the class of Hamiltonian torus homeomorphisms.

description: The negative ion chemical ionization (NICI) mass spectrometry of thirty-nine polycyclic aromatic hydrocarbons (PAH) was investigated. The methane NICI mass spectra of PAH are dominated by the molecular anion for species which show high NICI sensitivity, and by the molecular anion plus adduct ions for insensitive species. PAH adducts are formed under NICI conditions between the molecular PAH species in the gas phase and radical species present in the methane plasma. The alkyl-PAH adduct species is subsequently ionized by resonance capture of a low energy thermal electron. NICI spectra acquired using methane and deuteromethane as the reagent gases were used to elucidate two reaction schemes leading to the formation of the observed adduct ions. The absolute sensitivities for individual PAH varied over more than three orders of magnitude under methane NICI conditions, and the sensitivity and selectivity of detection for isomeric PAH were found to depend on the pressure and temperature in the ion source of the mass spectrometer. The selectivity of detection observed for parent PAH species was also observed for their alkylated homologues. The selectivity of NICI for isomeric PAH was used for the qualitative and quantitative determination of trace levels of PAH and alkylated-PAH in samples of a petroleum crude oil, diesel particulate matter, and urban air particulate matter.
title: Parochial patronage and the cure of souls in the diocese of Lincoln, 1209-1299
Creators: name: Weale, Colin Alexander
Publisher: name: The Open University
Year: 1987

description: This thesis is a study of the patrons, parishes and parochial clergy, including those appointed to parochial and private chapels, in the diocese of Lincoln from 1209 to 1299. Beginning with a definition of a parish and the exercise of the cure of souls, it goes on to examine what was required of the parochial clergy having such a responsibility. It continues with a study of the patrons and the exercise of their patronage, together with the limitations imposed by the bishops. It includes the appointments made by the religious houses in the diocese, both English and foreign, together with those of the laity, (including the crown), and the bishops. This is followed by a chapter on the rights of patronage and the many disputes involved in the exercise of those rights. The next chapter deals with the types of parish in the diocese, including the fragmentation of churches, their consolidation, the evils of holding churches in plurality, and the dispensations granted to that end. The appropriation of churches by the monasteries and the ordination of vicarages by the bishops is discussed. The payment of pensions by the clergy to their predecessors in a parish and to their monastic patrons in unappropriated benefices is also studied. A study is made of the clergy who served the parishes. The use of papal provisions to parishes and the problems involved is considered, followed by an account of clerical education and the efforts of the bishops to provide a better-trained and celibate clergy. I have also taken note of those clergy who left the parochial ministry for the religious life. This is followed by a special study of those who exercised the cure of souls in the parochial chapels of the diocese and the comparatively few who served the private chapels.

description: Using a novel and self-consistent approach that avoids the scalar-tensor identification in the Einstein frame, we reanalyze the viability of f(R) gravity within the context of solar-system tests. In order to do so, we depart from a simple but fully relativistic system of differential equations that describe a compact object in a static and spherically symmetric spacetime, and then we make suitable linearizations that apply to nonrelativistic objects such as the Sun. We then show clearly under which conditions the emerging chameleonlike mechanism can lead to a post-Newtonian parameter γ compatible with the observational bounds. To illustrate this method, we use several specific f(R) models proposed to explain the current acceleration of the Universe, and we show which of them are able to satisfy those bounds.

description: We investigate the description of the region behind the event horizon in rotating black holes in the AdS/CFT correspondence, using the rotating BTZ black hole as a concrete example. We extend a technique introduced by Kraus, Ooguri and Shenker [hep-th/0212277], based on analytically continuing amplitudes defined in a Euclidean space, to include rotation. In the rotating case, boundary amplitudes again have two different bulk descriptions, involving either integration only over the regions outside the black holes' event horizon, or integration over this region and the region between the event horizon and the Cauchy horizon (inner horizon). We argue that generally, the holographic map will relate the field theory to the region bounded by the Cauchy horizons in spacetime. We also argue that these results suggest that the holographic description of black holes will satisfy strong cosmic censorship.

AN EXPERIMENTAL STUDY OF ROCK VIDEO'S IMPACT UPON THE ATTITUDES AND VALUES OF NORMAL AND EMOTIONALLY DISTURBED ADOLESCENTS
Creators: name: Hugonnet, Mitchell Henry
Publisher: name: American University
Year: 2023

description: Rock music videos have been a staple of adolescent culture since 1981. Very little is known about the effects of rock music videos on those who view them. Some parents and educators are concerned that so-called "porn rock" videos, which contain sex, violence, or sexualized violence, may be psychologically damaging. In 1985, Senate hearings considered whether "porn rock" records and videos should be regulated. To assess the effects of music videos on the attitudes and values of adolescents, three experiments were conducted with different populations: forty-seven college students, sixty-seven high school students, and twenty-six emotionally disturbed male high school students. Subjects viewed and evaluated 35 minutes of music videos. Subjects were randomly assigned to watch either the experimental, "porn rock" videotape or the control, "soft rock" videotape. Immediately after viewing, all subjects answered the Semantic Differential, which assessed attitudes toward eleven aspects of adolescent life. College and high school subjects were also given two TAT cards and scales assessing Rape with Acceptance (RMA), Adversarial Sexual Beliefs (ASB), and Acceptance of Interpersonal Violence (AIV). The TAT cards were scored for sexual and aggressive imagery. The results of these experiments indicated that "porn rock" music videos have no effect upon adolescents' attitudes toward sexual activity and interpersonal aggression as measured by the TAT cards, RMA, ASB, and AIV scales. Significant results obtained on the Semantic Differential indicated that experimental college females were more inclined to condemn aggression than were control females. Experimental college males regarded their parents as being more active than control males. Experimental high school females regarded sexual activity less favorably than control females. Experimental high school males disapproved of recreational drug use more than control males. Emotionally disturbed high school males in the experimental condition viewed themselves and sexual activities as being less active than controls, while viewing school as more active. Virtually all adolescents preferred the visual images and music of the control music videos. Cumulatively, results from the Semantic Differential suggest either no effect or impulse inhibition. Allegedly harmful effects from exposure to music videos were not demonstrated in these experiments.

Light mesons and infrared behavior of the running coupling constant in QCD

Year: 2003
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: A previous method for handling bound states in QCD is briefly revisited. Taking advantage of the Feynman-Schwinger representation for the iterated quark propagator in an external field, it is possible to give closed representations for certain appropriate (second order) two point and four point Green functions, H^(2)(x-y) and H^(4)(x_1,x_2,y_1,y_2), as path integrals on quark world lines. Then, starting from reasonable assumptions on the Wilson line correlators, a Bethe-Salpeter equation for H^(4) and a Dyson-Schwinger equation for H^(2) can be obtained, which are consistent with the Goldstone theorem in the chiral limit. Such equations are too complicate to be solved directly. However, a reduced Salpeter equation can be derived which is tractable and has been applied to a calculation of the meson spectrum. The results are in general good agreement with the data, but with the important exceptions of the light pseudo scalars (that are related to the breaking of the chiral symmetry). In this scenario two important improvements can be introduced: a) the fixed coupling constant can be replaced by a running coupling constant α_{s}(Q^2) appropriately modified in the infrared region; b) the fixed mass in the reduced equation can be replaced for light quarks by an effective mass depending on the momentum of the particle, as suggested by the form of the DS equation. Then even the light pseudo scalar mesons can be made to agree with to their experimental value.

description: Rock music videos have been a staple of adolescent culture since 1981. Very little is known about the effects of rock music videos on those who view them. Some parents and educators are concerned that so-called "porn rock" videos, which contain sex, violence, or sexualized violence, may be psychologically damaging. In 1985, Senate hearings considered whether "porn rock" records and videos should be regulated. To assess the effects of music videos on the attitudes and values of adolescents, three experiments were conducted with different populations: forty-seven college students, sixty-seven high school students, and twenty-six emotionally disturbed male high school students. Subjects viewed and evaluated 35 minutes of music videos. Subjects were randomly assigned to watch either the experimental, "porn rock" videotape or the control, "soft rock" videotape. Immediately after viewing, all subjects answered the Semantic Differential, which assessed attitudes toward eleven aspects of adolescent life. College and high school subjects were also given two TAT cards and scales assessing Rape with Acceptance (RMA), Adversarial Sexual Beliefs (ASB), and Acceptance of Interpersonal Violence (AIV). The TAT cards were scored for sexual and aggressive imagery. The results of these experiments indicated that "porn rock" music videos have no effect upon adolescents' attitudes toward sexual activity and interpersonal aggression as measured by the TAT cards, RMA, ASB, and AIV scales. Significant results obtained on the Semantic Differential indicated that experimental college females were more inclined to condemn aggression than were control females. Experimental college males regarded their parents as being more active than control males. Experimental high school females regarded sexual activity less favorably than control females. Experimental high school males disapproved of recreational drug use more than control males. Emotionally disturbed high school males in the experimental condition viewed themselves and sexual activities as being less active than controls, while viewing school as more active. Virtually all adolescents preferred the visual images and music of the control music videos. Cumulatively, results from the Semantic Differential suggest either no effect or impulse inhibition. Allegedly harmful effects from exposure to music videos were not demonstrated in these experiments.

description: This paper examines the impact of co-operatives on oligopolistic industries. The theoretical analysis suggests that the existence of a co-operative in the fertilizer industry can improve efficiency. In reality, however, the existing co-operative appears to behave more like a profit maximizing firm, resulting in continued market imperfections.

description: We consider a multichannel wire with a disordered region of length $L$ and a reflecting boundary. The reflection of a wave of frequency $ω$ is described by the scattering matrix $\mathcal{S}(ω)$, encoding the probability amplitudes to be scattered from one channel to another. The Wigner-Smith time delay matrix $\mathcal{Q}=-\mathrm{i}\, \mathcal{S}^\dagger\partial_ω\mathcal{S}$ is another important matrix encoding temporal aspects of the scattering process. In order to study its statistical properties, we split the scattering matrix in terms of two unitary matrices, $\mathcal{S}=\mathrm{e}^{2\mathrm{i}kL}\mathcal{U}_L\mathcal{U}_R$ (with $\mathcal{U}_L=\mathcal{U}_R^\mathrm{T}$ in the presence of TRS), and introduce a novel symmetrisation procedure for the Wigner-Smith matrix: $\widetilde{\mathcal{Q}} =\mathcal{U}_R\,\mathcal{Q}\,\mathcal{U}_R^\dagger = (2L/v)\,\mathbf{1}_N -\mathrm{i}\,\mathcal{U}_L^\dagger\partial_ω\big(\mathcal{U}_L\mathcal{U}_R\big)\,\mathcal{U}_R^\dagger$, where $k$ is the wave vector and $v$ the group velocity. We demonstrate that $\widetilde{\mathcal{Q}}$ can be expressed under the form of an exponential functional of a matrix Brownian motion. For semi-infinite wires, $L\to\infty$, using a matricial extension of the Dufresne identity, we recover straightforwardly the joint distribution for $\mathcal{Q}$'s eigenvalues of Brouwer and Beenakker [Physica E 9 (2001) p. 463]. For finite length $L$, the exponential functional representation is used to calculate the first moments $\langle\mathrm{tr}(\mathcal{Q})\rangle$, $\langle\mathrm{tr}(\mathcal{Q}^2)\rangle$ and $\langle\big[\mathrm{tr}(\mathcal{Q})\big]^2\rangle$. Finally we derive a partial differential equation for the resolvent $g(z;L)=\lim_{N\to\infty}(1/N)\,\mathrm{tr}\big\{\big( z\,\mathbf{1}_N - N\,\mathcal{Q}\big)^{-1}\big\}$ in the large $N$ limit.

CONDITIONED TASTE AVERSIONS IN RATS AS A BEHAVIORAL BASELINE TO ASSESS THE DISCRIMINATIVE STIMULUS PROPERTIES OF PHENCYCLIDINE

description: Typically, drug discrimination is examined within the context of operant conditioning (cf. Stolerman & Shine, 1985). In such designs, one behavior is reinforced during sessions preceded by an injection of a drug and a second behavior is reinforced by an injection of the drug vehicle. The discrimination is evidenced by differential responding in the presence and absence of the drug stimulus. In the present series of experiments, an alternative procedure for assessment of drug-discrimination learning was examined, i.e., conditioned-taste aversion learning (cf. Riley & Tuck, 1985). In conditioned taste-aversion learning, an animal is injected with a toxin following consumption of a novel taste. In such a design, animals avoid consumption of that taste on subsequent exposures. The question posed in the present series of experiments was whether an aversion to a taste would be acquired and displayed in one specific drug state, while the same taste would be consumed in another drug condition. Prior to assessing drug-discrimination learning within the taste-aversion design, a dose of a drug had to be chosen that had no potential for supporting conditioning itself (Experiment 1), no unconditioned suppressant effects on consumption (Experiment 2), and was able to serve as a discriminative stimulus in an operant paradigm (Experiment 3). Based on the results of the first three experiments, a dose of 1.8 mg/kg of phencyclidine was chosen to determine if the taste-aversion design could serve as a baseline for drug-discrimination learning. In Experiment 4, different groups of rats were trained in a conditioned taste-aversion paradigm with either the presence or absence of PCP as a signal for a saccharin-LiCl pairing. Specifically, for Group P-L on days when PCP was injected 10 min prior to saccharin presentation, LiCl was injected immediately following saccharin access. On days when distilled water was injected 10 min prior to saccharin presentation, however, no LiCl was injected. For Group W-L, these conditions were reversed. Differential consumption in the presence or absence of the drug stimulus emerged after three conditioning trials. In addition, substituting different doses of PCP produced a generalization gradient around the training dose. The rapid control acquired by the drug stimulus in this procedure and the absence of any other confounding stimuli, e.g., a reinforcing stimulus, suggest that the conditioned taste-aversion design may be an efficient method for classifying drugs on the basis of their discriminative stimulus properties.

description: It is shown that the extra supersymmetry of tensionless superstring and super $p$-brane is accompanied by the presence of new bosonic gauge symmetries. It permits to use composed coordinates encoding all physical degrees of freedom of the model and invariant under these gauge symmetries and the enhanced $κ$-symmetry. It is proved that the composed gauge invariant coordinates coincide with the componets of symplectic supertwistor realizing a linear representation of the hidden OSp(1,2M) symmetry of the super $p$-brane Lagrangian. A connection of the presented gauge symmetries with massless higher spin gauge theories and a symmetric phase of $M$/string-theory is discussed.
