description: We investigate the stability of incompressible, exact, non-ideal magnetorotational (MRI) modes against parasitic instabilities. Both Kelvin-Helmholtz and tearing-mode parasitic instabilities may occur in the dissipative regimes accessible to current numerical simulations. We suppose that a primary MRI mode saturates at an amplitude such that its fastest parasite has a growth rate comparable to its own. The predicted alpha parameter then depends critically on whether the fastest primary and parasitic modes fit within the computational domain and whether non-axisymmetric parasitic modes are allowed. Hence even simulations that resolve viscous and resistive scales may not saturate properly unless the numerical domain is large enough to allow the free evolution of both MRI and parasitic modes. To minimally satisfy these requirements in simulations with vertical background fields, the vertical extent of the domain should accommodate the fastest growing MRI mode while the radial and azimuthal extents must be twice as large. The fastest parasites have horizontal wavelengths roughly twice as long as the vertical wavelength of the primary.

description: We present a simple model to describe the lowest-subbands surface scattering in locally oxidized silicon nanowires grown in the [110] direction. To this end, we employ an atomistically scaled effective mass model projected from a three-dimensional effective mass equation and apply a quantum transport formalism to calculate the conductance for typical potential profiles. Comparison of our results with hole-transport calculations using atomistic models in conjunction with density functional theory (DFT) points to an intra-subband scattering mechanism from a potential well.

description: The article discusses the mechanism of frictional interaction of polymeric materials with pulp. The essence of the method lies in the fact that the FCA of polymeric materials with cotton is composed of elementary contact areas characterized by an average width bi and a length ℓ under the influence of a normal load G to cotton, the distribution pattern and magnitude of which are adequate with similar parameters for a single fiber in a strained state -deformed state under normal load G.
Constraining Low-Frequency Alfvenic Turbulence in the Solar Wind Using Density Fluctuation Measurements

description: One proposed mechanism for heating the solar wind, from close to the sun to beyond 10 AU, invokes low-frequency, oblique, Alfven-wave turbulence. Because small-scale oblique Alfven waves (kinetic Alfven waves) are compressive, the measured density fluctuations in the solar wind place an upper limit on the amplitude of kinetic Alfven waves and hence an upper limit on the rate at which the solar wind can be heated by low-frequency, Alfvenic turbulence. We evaluate this upper limit for both coronal holes at 5 solar radii and in the near-Earth solar wind. At both radii, the upper limit we find is consistent with models in which the solar wind is heated by low-frequency Alfvenic turbulence. At 1 AU, the upper limit on the turbulent heating rate derived from the measured density fluctuations is within a factor of 2 of the measured solar wind heating rate. Thus if low-frequency Alfvenic turbulence contributes to heating the near-Earth solar wind, kinetic Alfven waves must be one of the dominant sources of solar wind density fluctuations at frequencies of order 1 Hz. We also present a simple argument for why density fluctuation measurements do appear to rule out models in which the solar wind is heated by non-turbulent high-frequency waves ``sweeping'' through the ion-cyclotron resonance, but are compatible with heating by low-frequency Alfvenic turbulence.

Formation of young boxy/peanut bulges in ringed barred galaxies

Year: 2009
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We investigate whether the formation mechanism of boxy and peanut-shaped (B/PS) bulges could depend on the gas content of the galaxy. We have performed N-body simulations with and without a gaseous component. In the second case star formation/feedback recipes have also been implemented to create new stellar populations. As in many previous studies, in our N-body collisionless simulation, the B/PS is due to the classical break in the z mirror symmetry lasting roughly 200 Myr. When a gaseous component and star formation recipes are added to the simulation, the bulge-growing mechanism is quite different. The young stellar population that is born in the thin gaseous disc rapidly populates vertical resonant orbits triggered by the combined effects of the linear horizontal and vertical ILRs. This leads to a B/PS bulge mainly made of stellar material younger than the surrounding population. The non-linear analysis of the orbital structure shows that the main orbit family responsible for the B/PS is not the same in the two cases. The 2:2:1 orbits prevail in the collisionless simulation whereas additional asymmetrical families contribute to the B/PS if a dissipative component is present and can form new stars. We found that 2:3:1 and 2:5:1 orbits trap a significant fraction of the mass. A flat ringed discy stellar component also appears simultaneously with the thickening of the young population. It is due to the star formation in a nuclear gaseous disc located in the central kpc, inside the ILR, and accumulated there by the torques exerted by the large-scale bar. Remarkably, it remains flat throughout the simulation although it develops a nuclear bar, leading to a double-barred galaxy. We predict that two populations of B/PS bulges could exist and even coexist in the same galaxy.

description: SAS® has many tools that can be used for data analysis. From Freqs and Means to Tabulates and Univariates, SAS can present a synopsis of data values relatively easily. However, there is a difference between what the data are, and what the data mean. In order to take this next step, I would like to go beyond the basics and introduce correlation and hypothesis testing using regression models. A brief statistical background will be included, along with coding examples for correlation and linear regression.

Una nuova pulsar e i gamma ray che emette è stata scoperta "nascosta" in bella vista tra i dati del Fermi Gamma-ray Space Telescope. Ad ottenere questo risultato un team internazionale guidato da ricercatori dell'Istituto Max Planck per la Fisica della Gravitazione (Albert Einstein Institute, AEI) di Hannover, in Germania. Ma non sarebbe stato possibile raggiungere tale obiettivo senza il progetto di volontariato Einstein@home. I migliorati metodi di analisi dei dati e la potenza di calcolo del progetto Einstein@Home sono stati, infatti, la chiave del loro successo
Parental resistance in child guidance casework : an analysis of initial resistance manifested by parents and the relation to casework services for disturbed children, based on Child Guidance Clinic cases, Greater Vancouver, 1954
Creators: name: Kennedy, Ramona Frances
Publisher: name: University of British Columbia
Year: 2012

description: A pertinent problem in child guidance settings is the apparent inability of a considerable number of parents to involve themselves in treatment. This results in seriously limiting the amount of help that can be given to the child, or results in the parents withdrawing from the agency leaving the problem untouched. It was therefore considered important to attempt to isolate resistance, as manifested by parents, to casework services during the intake study. Some of the causative factors in resistance are discussed in general terms, as background. A small group of cases (6) were then chosen for detailed examination. In all of these, a high degree of resistance was manifested. The defense mechanisms used to manifest resistance are described in general, and analysed in the specific cases. Skills and techniques which the social worker used to decrease initial resistance were then tabulated; and from these certain common denominators became evident. The findings indicate a need for some refinement of intake procedures. There is evidently need also for greater effort on the part of social workers to decrease initial resistance, since the capacity of parents to involve themselves in treatment appears to be dependent upon the favorable conditions created for them by the intake worker. Resistance is a complex phenomenon however, and demands further research.

description: This study seeks to investigate the asymmetric effects of fiscal deficit on monetary policy transmission in Tanzania by using quarterly time series data for the period 2001: I to 2019: IV. In the analysis, which is based on the theory of sovereign risk premium, use is made of the asymmetric cointegration modelling in a non-linear autoregressive distributed lag model to distinguish the effects of fiscal deficit on interest rates, exchange rates and inflation. The findings indicate that interest rate and exchange rate react differently to negative and positive changes in fiscal deficit over the long run, and, inflation responds differently to such changes over the long run and short run period. The findings also revealed that interest rate is more sensitive to the worsening in fiscal deficit; and, accordingly fiscal consolidation is an essential requirement for effective transmission of the monetary policy. In particular, implementation of the price based policy framework in Tanzania should be considered carefully, as persistent rise in budget deficits would eventually counter the effectiveness of monetary policy by keeping market interest rates and inflation at high levels. The findings provide evidence in favour of a fiscal policy to stabilise monetary policy variables, but also highlights the importance of long-term fiscal sustainability for the attainment of monetary policy objectives.

description: We explore the sparticle and Higgs spectroscopy of an SU(5) inspired extension of the constrained minimal supersymmetric standard model (CMSSM). The universal soft parameter m_0 is replaced by m_{\bar 5} and m_{10}, where m_{\bar 5} and m_{10} denote universal soft scalar masses associated with fields in the five and ten dimensional representations of SU(5). The special case m_{\bar 5} << m_{10} yields a rather characteristic sparticle spectroscopy which can be tested at the LHC. We highlight a few benchmark points in which the lightest neutralino saturates the WMAP bound on cold dark matter abundance.

description: Mounting experimental and theoretical evidence suggests that coherent quantum effects play a role in the efficient transfer of an excitation from a chlorosome antenna to a reaction center in the Fenna-Matthews-Olson protein complex. However, it is conceivable that a satisfying alternate interpretation of the results is possible in terms of a classical theory. To address this possibility, we consider a class of classical theories satisfying the minimal postulates of macrorealism and frame Leggett-Garg-type tests that could rule them out. Our numerical simulations indicate that even in the presence of decoherence, several tests could exhibit the required violations of the Leggett-Garg inequality. Remarkably, some violations persist even at room temperature for our decoherence model.

description: In this work we present a detailed computational study of structural and elastic properties of cubic AlGaInN alloys in the framework of Keating valence force field model, for which we perform accurate parametrization based on state of the art DFT calculations. When analyzing structural properties, we focus on concentration dependence of lattice constant, as well as on the distribution of the nearest and the next nearest neighbour distances. Where possible, we compare our results with experiment and calculations performed within other computational schemes. We also present a detailed study of elastic constants for AlGaInN alloy over the whole concentration range. Moreover, we include there accurate quadratic parametrization for the dependence of the alloy elastic constants on the composition. Finally, we examine the sensitivity of obtained results to computational procedures commonly employed in the Keating model for studies of alloys.
Effect of CO desorption and coadsorption with O on the phase diagram of a Ziff-Gulari-Barshad model for the catalytic oxidation of CO

description: We study the effect of coadsorption of CO and O on a Ziff-Gulari-Barshad (ZGB) model with CO desorption (ZGB-d) for the reaction CO + O --> CO_2 on a catalytic surface. Coadsorption of CO on a surface site already occupied by an O is introduced by an Eley-Rideal-type mechanism that occurs with probability p, 0 <= p <= 1. We find that, besides the well known effect of eliminating the second-order phase transition between the reactive state and an O-poisoned state, the coadsorption step has a strong effect on the transition between the reactive state and the CO-poisoned state. The coexistence curve between these two states terminates at a critical value k_c of the desorption rate k which now depends on p. Our Monte Carlo simulations and finite-size scale analysis indicate that k_c decreases with increasing values of p. For p=1, there appears to be a sharp phase transition between the two states only for k at(or near) zero.

description: We study dynamic ground state properties in the crossover from weak (BCS) to strong coupling (BEC) superfluidity. Our approach is based on the attractive Hubbard model which is analyzed by the dynamical mean field theory (DMFT) combined with the numerical renormalization group (NRG). We present an extension of the NRG method for effective impurity models to selfconsistent calculations with superconducting symmetry breaking. In the one particle spectra we show quantitatively how the Bogoliubov quasiparticles at weak coupling become suppressed at intermediate coupling. We also present results for the spin and charge gap. The extension of the NRG method to selfconsistent superconducting solutions opens the possibility to study a range of other important applications.

Probing Star Formation at Low Metallicity: The Radio Emission of Super Star Clusters in SBS0335-052

description: We present high-resolution radio continuum observations of the nascent starburst in the metal-poor galaxy SBS 0335-052. These radio data were taken with the Very Large Array and include observations at 0.7cm, 1.3cm, 2cm, 3.6cm, and 6cm. These observations enable us to probe the thermal radio nebulae associated with the extremely young star-forming regions in this galaxy. Two discrete and luminous star-forming regions are detected in the south of the galaxy that appear to be associated with massive star clusters previously identified at optical wavelengths. However, the remaining optically-identified massive star clusters are not clearly associated with radio emission (either thermal or non-thermal) down to the sensitivity limits of these radio data. The spectral energy distributions of the two radio-detected clusters are consistent with being purely thermal, and the entire region has an inferred ionizing flux of ~1.2 x 10^ 53 s^-1, which is equivalent to ~12,000 "typical" O-type stars (type O7.5 V). The observations presented here have resolved out a significant contribution from diffuse non-thermal emission detected previously, implying a previous episode of significant star formation. The current star formation rate (SFR) for this southern region alone is ~1.3 M_sun yr^-1, or ~ 23M_sun yr^-1 kpc^-2. This SFR derived from thermal radio emission also suggests that previous optical recombination line studies are not detecting a significant fraction of the current star formation in SBS 0335-052. From model fits to the radio spectral energy distribution, we infer a global mean density in the two youngest clusters of n_e > 10^3-10^4 cm^-3. In addition, a comparison between the compact and diffuse radio emission indicates that up to ~50% of the ionizing flux could be leaking out of the compact HII regions.

description: A simple method to control molecular translation with a chemical reaction is demonstrated. Slow NO molecules have been produced by partially canceling the molecular beam velocity of NO$_2$ with the recoil velocity of the NO photofragment. The NO$_2$ molecules were photodissociated using a UV laser pulse polarized parallel to the molecular beam. The spatial profiles of NO molecules showed two peaks corresponding to decelerated and accelerated molecules, in agreement with theoretical prediction. A significant portion of the decelerated NO molecules stayed around the initial dissociation positions even several hundred nanoseconds after their production.

We utilize a newly developed non-perturbative heat kernel asymptotic expansion on homogeneous Abelian bundles over Riemannian manifolds in order to compute the one-loop effective action for scalar and spinor fields in curved spacetime under the influence of a strong covariantly constant electromagnetic field. In this framework we derived, in particular, the gravitational corrections, up to linear terms in Riemannian curvature, to Schwinger's result for the creation of particles in a strong electric field.

description: Dialogue systems are designed to offer human users social support or functional services through natural language interactions. Traditional conversation research has put significant emphasis on a system’s response-ability, including its capacity to understand dialogue context and generate appropriate responses. However, the key element of proactive behavior—a crucial aspect of intelligent conversations—is often overlooked in these studies. Proactivity empowers conversational agents to lead conversations towards achieving pre-defined targets or fulfilling specific goals on the system side. Proactive dialogue systems are equipped with advanced techniques to handle complex tasks, requiring strategic and motivational interactions, thus representing a significant step towards artificial general intelligence. Motivated by the necessity and challenges of building proactive dialogue systems, we provide a comprehensive review of various prominent problems and advanced designs for implementing proactivity into different types of dialogue systems, including open-domain dialogues, task-oriented dialogues, and information-seeking dialogues. We also discuss real-world challenges that require further research attention to meet application needs in the future, such as proactivity in dialogue systems that are based on large language models, proactivity in hybrid dialogues, evaluation protocols and ethical considerations for proactive dialogue systems. By providing a quick access and overall picture of the proactive dialogue systems domain, we aim to inspire new research directions and stimulate further advancements towards achieving the next level of conversational AI capabilities, paving the way for more dynamic and intelligent interactions within various application domains.

description: We have performed shell-model calculations of the half-lives and neutron-branching probabilities of the r-process waiting point nuclei at the magic neutron number N=82. These new calculations use a larger model space than previous shell model studies and an improved residual interaction which is adjusted to recent spectroscopic data around A=130. Our shell-model results give a good account of all experimentally known half-lives and $Q_β$-values for the N=82 r-process waiting point nuclei. Our half-life predictions for the N=82 nuclei with Z=42--46 agree well with recent estimates based in the energy-density functional method.

description: This is one of the first studies made, in a rural area of British Columbia, of the co-operation between the Provincial Probation Branch and the Social Welfare Branch of the Government of British Columbia in the allocation of responsibility for the probation supervision of, and the casework services to, certain male juvenile delinquents. The juvenile delinquents under consideration in this study are those who were known to the Social Welfare Branch or who were in need of a specific service provided by that Branch at the time that they were brought before the Court. The research material was obtained from the files of one probation office and cover all cases opened over a three year period from 1953 to 1956. This probation office served a territory that was also served by one district supervisor and six welfare workers of the Social Welfare Branch. The study compares the characteristics of a group of 28 juvenile delinquents who were known to both the Provincial Probation Branch and the Social Welfare Branch with those of a group of 99 delinquent juveniles who were referred to the Provincial Probation Branch by the Juvenile Courts but who had no contact with the Social Welfare Branch. The groups are compared on the basis of age, offence, family background, religious affiliation, school record, work record and recreational interests. The study then presents seven case digests in detail, to show how the decision was reached between the probation officer and the welfare worker as to who would provide probation supervision, casework services to the child and casework services to the parents. These cases present a brief social history of the juvenile delinquent, a tentative social diagnosis of his troubles, an evaluation of his needs and a suggested solution to his problems. The results of the study indicate that there is no hard and fast rule to be used in allocating responsibilities towards the juvenile delinquents in the group under study between the two Government Branches. Each case must be considered on its own merits so that the agencies can cooperate to function in the best interests of the client. The usual social work practise of dealing with each client as a unique individual must be carried over into the field of corrections if the needs of the child are to be met by the social workers.

description: Stanford University is a large research institution, with over $1.6 billion in sponsored research.  Along with other sources of funding, this produces an enormous amount of research.  The results of this work are published in journals or books, presented at conferences, taught in classes and workshops, and captured in data sets.  In order to help Stanford work towards new opportunities and fulfill its mission, we seek to better understand and catalog this research output, capture it in preservable form, and understand how it is interconnected.

Stanford currently maintains separate systems for tracking researchers, grants, publications and projects, but it has no system for combining this information and further tracking and managing its research output: the tangible artifacts of articles, data, books and projects that advance human knowledge.  RIALTO will attempt to close that loop, helping provide a holistic picture of the University’s activity and impact, while also eliminating waste through inefficient, duplicate data entry and opportunity costs stemming from lack of information.

description: We propose a mesoscopic circuit in the quantum Hall effect regime comprising two uncorrelated single-particle sources and two distant Mach-Zehnder interferometers with magnetic fluxes, which allows in a controllable way to produce orbitally entangled electrons. Two-particle correlations appear as a consequence of erasing of which path information due to collisions taking place at distant interferometers and in general at different times. The two-particle correlations manifest themselves as an Aharonov-Bohm effect in noise while the current is insensitive to magnetic fluxes. In an appropriate time-interval the concurrence reaches a maximum and a Bell inequality is violated.
