The Effect of 10% Povidone-Iodine on S. Mutans Levels in Children with "Early Childhood Caries"
Creators: name: Sharifzadeh-Amin, Maryam
Publisher: name: University of British Columbia
Year: 2011

description: An antibacterial agent that is effective and acceptable to young children will be a useful supplement to behaviour modification techniques for the prevention of early childhood caries. Objective: The objective of the present study was to determine the effect of 10% povidone-iodine solution (betadine) on S. mutans in children with dental caries. Methods: The study was designed as a randomized single blind, no treatment control trial. Twenty-five children between 2 and 6.8 years of age with unremarkable medical history were recruited from a private pediatric dental practice in Burnaby, BC. All subjects were scheduled for dental rehabilitation under general anesthesia. Parents completed a consent form and a variety of survey instruments. Before intubation, height and weight of all participants were recorded and these measurements were repeated at all subsequent study appointments for children in experimental group. Dental examination data and the plaque sample were collected after intubation. Following dental treatment, children were randomly assigned to the experimental group (N=13) or the control group (N=12). Experimental children had betadine applied 3 times at 2-month intervals and no treatment was employed for control children. After 6 months, both experimental and control children received another dental examination and a mouth swab was taken from all subjects. Plaque samples were cultured for total bacteria and S. mutans. Results: Betadine application was well-accepted by all experimental children. No adverse effect was reported. At baseline, experimental and control children had similar dietary habits, dmfs, and S. mutans levels. All children's S. mutans counts decreased significantly at 6 months (P=0.0004). Although the overall S. mutans decrease was greater for experimental children than for control children, this difference was not significant (P=0.58). Ten of 13 experimental children had a ≥1 log₁₀ decrease in S. mutans over 6 months, compared with 7 of 12 control children. The number of children with new cavitated carious lesions at 6 months was the same for both groups. For this group of children, the effect of rehabilitation under general anesthesia may have made a major contribution to decreasing plaque S. mutans at 6-months post-treatment that overwhelmed the effect of betadine. Conclusion: Results suggest that betadine may have an effect on S. mutans, but additional research with more subjects and a longer time period after application are indicated.

description: A covariant quantization scheme employing reducible representations of canonical commutation relations with positive-definite metric and Hermitian four-potentials is tested on the example of quantum electrodynamic fields produced by a classical current. The scheme implies a modified but very physically looking Hamiltonian. We solve Heisenberg equations of motion and compute photon statistics. Poisson statistics naturally occurs and no infrared divergence is found even for pointlike sources. Classical fields produced by classical sources can be obtained if one computes coherent-state averages of Heisenberg-picture operators. It is shown that the new form of representation automatically smears out pointlike currents. We discuss in detail Poincaré covariance of the theory and the role of Bogoliubov transformations for the issue of gauge invariance. The representation we employ is parametrized by a number that is related to Rényi's $α$. It is shown that the ``Shannon limit" $α\to 1$ plays here a role of correspondence principle with the standard regularized formalism.

description: The search for di-Higgs final states is typically limited at the LHC to the dominant gluon fusion channels, with weak boson fusion only assuming a spectator role. In this work, we demonstrate that when it comes to searches for resonant structures that arise from iso-singlet mixing in the Higgs sector, the weak boson fusion sideline can indeed contribute to winning the discovery game. Extending existing experimental resonance searches by including both contributions is therefore crucial.

Optical-parametric-oscillator solitons driven by the third harmonic

Year: 2004
Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: We introduce a model of a lossy second-harmonic-generating (chi^2) cavity externally pumped at the third harmonic, which gives rise to driving terms of a new type, corresponding to a cross-parametric gain. The equation for the fundamental-frequency (FF) wave may also contain a quadratic self-driving term, which is generated by the cubic nonlinearity of the medium. Unlike previously studied phase-matched models of chi^2 cavities driven at the second harmonic (SH) or at FF, the present one admits an exact analytical solution for the soliton, at a special value of the gain parameter. Two families of solitons are found in a numerical form, and their stability area is identified through numerical computation of the perturbation eigenvalues (stability of the zero solution, which is a necessary condition for the soliton's stability, is investigated in an analytical form). One family is a continuation of the special analytical solution. At given values of parameters, one soliton is stable and the other one is not; they swap their stability at a critical value of the mismatch parameter. The stability of the solitons is also verified in direct simulations, which demonstrate that the unstable pulse rearranges itself into the stable one, or into a delocalized state, or decays to zero. A soliton which was given an initial boost C starts to move but quickly comes to a halt, if the boost is smaller than a critical value C_cr. If C>C_cr, the boost destroys the soliton (sometimes, through splitting into two secondary pulses). Interactions between initially separated solitons are investigated too. It is concluded that stable solitons always merge into a single one. In the system with weak loss, it appears in a vibrating form, slowly relaxing to the static shape. With stronger loss, the final soliton emerges in the stationary form.

description: The Bunch-Davies state appears precisely thermal to a free-falling observer in de Sitter space. However, precise thermality is unphysical because it violates energy conservation. Instead, the true spectrum must take a certain different form, with the Boltzmann factor $\exp(-βω_k)$ replaced by $\exp(ΔS)$, where $S$ is the entropy of the de Sitter horizon. The deviation from precise thermality can be regarded as an explicitly calculable correction to the Bunch-Davies state. This correction is mandatory in that it relies only on energy conservation. The modified Bunch-Davies state leads, in turn, to an ${\cal O} (H/M_p)^2$ modification of the primordial power spectrum of inflationary perturbations, which we determine.

Stability of a parametric harmonic oscillator with dichotomic noise

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The harmonic oscillator is a powerful model that can appear as a limit case when examining a nonlinear system. A well known fact is, that without driving, the inclusion of a friction term makes the origin of the phase space -- which is a fixpoint of the system -- linearly stable. In this work we include a telegraph process as perturbation of the oscillator's frequency, for example to describe the motion of a particle with fluctuating charge gyrating in an external magnetic field. Increasing intensity of this colored noise is capable of changing the quality of the fixed point. To characterize the stability of the system, we use a stability measure, that describes the growth of the displacement of the system's phase space position and express it in a closed form. We expand the respective exponent for light friction and low noise intensity and compare both, the exact analytic solution and the expansion to numerical values. Our findings allow stability predictions for several physical systems.

description: Die Integration von suchterkrankten Menschen in die soziale Gemeinschaft stellt für die Klinische Soziale Arbeit einer große Herausforderung dar. Sie agiert hier in einem Spannungsfeld zwischen individuellem Verhalten der Klienten_innen und den strukturellen Verhältnissen der Gesellschaft. Auf die Befähigung einer sinnstiftenden und ein daseinsmächtiges Leben ermöglichender Arbeit nachgehen zu können, wird von Martha Nussbaum in ihren Schriften zum Capability Approach sehr deutlich hingewiesen und sie sieht darin einen gewichtigen Faktor der gesellschaftlichen Teilhabe. In der vorliegenden explorativen Studie wurden vor dem theoretischen Hintergrund des Capability Approach Teilnehmer_innen und Nichtteilnehmer_innen des niederschwelligen, von der Caritas in Vorarlberg betriebenen Arbeitsprojekts „Wald“, hinsichtlich ihrer Lebenszufriedenheit, ihrer Haltung zum Arbeitsprojekt als solchem und nach von ihnen bemerkten Veränderungen in den, den Big Five zuzuordnenden Persönlichkeitsmerkmalen, befragt. Die aus den quantitativen Befragungen gewonnenen Daten wurden in Hinblick auf die Fragestellungen empirisch ausgewertet. In seiner Konzeption setzt das Arbeitsprojekt, ganz im Sinne der internationalen Definition der Sozialen Arbeit, auf Selbstbestimmung und Partizipation der Teilnehmer_innen. Die Klinische Soziale Arbeit erfüllt in diesem Kontext nicht nur ihren per Definition direkt behandelnden Ansatz in der Unterstützung von schwer erreichbaren Klienten_innen, sondern schafft zusätzlich die Bedingungen, um diesen die benötigten Befähigungsräume bereitzustellen. Die Studie legt nahe, dass sowohl das Schaffen von befähigenden Strukturen als auch der Einsatz von verhaltensorientierten Methoden passende Mittel für die Soziale Arbeit sind, Menschen in ihrer Entwicklung hin zu einem daseinsmächtige Leben zu unterstützen.
Non-equilibrium spin polarization effects in spin-orbit coupling system and contacting metallic leads

description: We study theoretically the current-induced spin polarization effect in a two-terminal mesoscopic structure which is composed of a semiconductor two-dimensional electron gas (2DEG) bar with Rashba spin-orbit (SO) interaction and two attached ideal leads. The nonequilibrium spin density is calculated by solving the scattering wave functions explicitly within the ballistic transport regime. We found that for a Rashba SO system the electrical current can induce spin polarization in the SO system as well as in the ideal leads. The induced polarization in the 2DEG shows some qualitative features of the intrinsic spin Hall effect. On the other hand, the nonequilibrium spin density in the ideal leads, after being averaged in the transversal direction, is independent of the distance measured from the lead/SO system interface, except in the vicinity of the interface. Such a lead polarization effect can even be enhanced by the presence of weak impurity scattering in the SO system and may be detectable in real experiments.

Dabei entsteht eine desorganisierte Wohnung nicht allein durch Passivität, sondern zeigt sich als innerpsychischen Konflikt nach außen. Die Komplexität des desorganisierten Wohnens umfasst sowohl die Wohnform selbst wie auch die Ursachen und Auswirkungen. Um bedürfnisgerecht handeln zu können, benötigt es seitens des professionellen Unterstützungssystems eine umfassende Kenntnis des Phänomens. Die Erforschung der Auswirkungen aus der Perspektive der betroffenen Menschen soll Aufschluss darüber geben, wie adäquat interveniert werden kann. Anhand einer Einzelfallstudie sollen die Diversität und Komplexität dargestellt werden, woraus sich die Flexibilität professioneller Helfer*innen ableiten lässt. Die Grounded Theory und der damit verbundene zirkuläre Prozess ermöglichen es, trotz geringer Erforschung des Phänomens, die erhobenen Daten zu erfassen und zu kategorisieren.
description: Due to society’s understanding of order, humans suffering from hoarding disorder experience debasement and a lack of understanding. Yet, hoarding disorders do not arise from passive behaviour but appears as a psychological inner conflict presented to the outside world. The complexity of hoarding disorder includes not only the form of living but also causes and effects. In order to act in accordance with the needs of people affected by hoarding disorder, professionals must have full knowledge about the disorder. By examining the effects from people affected by the disorder, the results should provide new ideas on how to intervene adequately. The diversity and complexity of hoarding disorder will be described by means of a single case study. The results will show that professionals have to be flexible in order to help people. The so-called Grounded Theory and its circular process made it possible to categorise and analyse the research data, despite the fact that the disorder has rarely been examined.
title: The effect of cannabidiol in tuberous sclerosis complex
Creators: name: Serra, Inês da Silva
Publisher: name: University of Reading
Year: 2019

description: Tuberous Sclerosis Complex (TSC) is a rare genetic disease caused by TSC1 or TSC2 mutations, characterized by overactivation of mechanistic target of rapamycin (mTOR). Among others, this leads to increased cell growth, altered cellular structure and migration. Consequently, TSC patients exhibit multiorgan tumours, namely in the brain, with neurological and neuropsychiatric manifestations affecting the majority of individuals. Central nervous system (CNS) alterations are a significant contributor to decreased quality of life and increased morbidity and caregiver dependence. Although pharmacological options are available to manage specific CNS features of TSC, these are limited and not curative, creating a high demand for new entities that address these symptoms. In the search for novel compounds that target CNS manifestations in TSC, I focused on cannabidiol, a phytocannabinoid present in Cannabis, seeking out to explore and identify which CBD effects could contribute positively to the management of TSC. With a zebrafish model of TSC, I demonstrated that CBD reduced the activation of the mTOR downstream molecule rpS6, cell size and anxiety-like behaviour. Using a rat model of TSC, the Eker rat, I described a novel cerebellar characterization and identified mutation-dependent cell size and density alterations, modified by CBD. Following long-term CBD administration and behavioural analysis, I corroborated the mild phenotype of the Eker rat and the action of CBD on rpS6. The Eker mutation also appeared to have no effect on seizure susceptibility following shortterm CBD treatment. In both cases, mutation and treatment revealed minimal disease-modifying effects. The results presented in this thesis provide novel information on the in vivo effects of CBD in the presence of TSC mutations and additional insight on the appropriateness of TSC models to explore CNS manifestations. The data presented is a valuable contribution to the development of novel interventions for TSC and to the study of TSC itself.

By means of a simple experimental setup based on fourth-order (or two-photon) interferometry, we show that our theoretical model provides a good description for down-converted fields carrying orbital angular momentum.

description: A general self-consistency approach allows a thorough treatment of the corrections to the standard mean-field approximation (MFA). The natural extension of standard MFA with the help of a cumulant expansion leads to a new point of view on the MF theories. The proposed approach can be used for a systematic treatment of fluctuation effects of various length scales and, perhaps, for the development of a new coarse graining procedure. We outline and justify our method by some preliminary calculations. Concrete results are given for the critical temperature and the Landau parameters of the theory -- the field counterpart of the Ising model. An important unresolved problem of the modern theory of phase transitions -- the problem for the calculation of the true critical temperature, is considered within the framework of the present approach.

description: A tidal disruption event (TDE) occurs when a star passes too close to a supermassive black hole and gets torn apart by its gravitational tidal field. After the disruption, the stellar debris form an expanding gaseous stream. The morphology and evolution of this stream is particularly interesting as it ultimately determines the observational properties of the event itself. In this work we perform 3D hydrodynamical simulations of the TDE of a star modelled as a polytropic sphere of index γ = 5/3, and study the gravitational stability of the resulting gas stream. We provide an analytical solution for the evolution of the stream in the bound, unbound and marginally bound case, that allows us to describe the stream properties and analyse the time-scales of the physical processes involved, applying a formalism developed in star formation context. Our results are that, when fragmentation occurs, it is fueled by the failure of pressure in supporting the gas against its self-gravity. We also show that a stability criterion that includes also the stream gas pressure proves to be far more accurate than one that only considers the black hole tidal forces, giving analytical predictions of the time evolution of the various forces associated to the stream. Our results point out that fragmentation occurs on timescales longer compared with the observational windows of these events and is thus not expected to give rise to significant observational features.

description: Die vorliegende Arbeit setzt sich mit der Beziehungsgestaltung im Kontext Klinischer Sozialer Arbeit auseinander. Der Fokus liegt dabei auf den Aspekten Nähe Und Distanz, Verletzlichkeit und Macht. Theoretische Grundlage ist ein psychodynamisch-sozialtherapeutischer Zugang. Als Grundlage für die durchgeführte Forschung dient das Tiefeninterview, dessen Ergebnisse anhand der Grounded Theory ausgewertet und interpretiert wurden. Als Resultat zeigt sich die Auswirkung der genannten Aspekte auf die Gestaltung der Helfenden Beziehung und die Wirksamkeit sozialarbeiterischer Intervention. Zudem hat sich das Setting als eine wesentliche Bedingung für die Beziehungsgestaltung herauskristallisiert. Bestätigt haben sich schließlich auch die aufgrund der theoretischen Bearbeitung aus psychoanalytischer/psychodynamischer Perspektive vermuteten Einflüsse von Übertragung und Gegenübertragung, die im Tiefeninterview deutlich zutage getreten sind.
description: The paper deals with relationship formation in the context of Clinical Social Work, focusing on aspects of closeness and distance as well as vulnerability and power. A psychodynamic-social therapeutic approach serves as theoretical background, research was conducted via in-depth interview, whose results have been evaluated and interpreted through Grounded Theory. Results show the impact of the mentioned aspects on the formation of the support relationship and the effectiveness of interventions of Social Work. Additionally, the Setting has proven to be a vital condition for relationship formation. Finally, the influence of transference and countertransference, which has been assumed due to the psychoanalytic/psychodynamic perspective of the theoretical work, could be confirmed, since both processes clearly came to the fore in the in-depth interview.

description: The realization of antiferromagnetic (AF) correlations in ultracold fermionic atoms on an optical lattice is a significant achievement. Experiments have been carried out in one, two, and three dimensions, and have also studied anisotropic configurations with stronger tunneling in some lattice directions. Such anisotropy is relevant to the physics of cuprate superconductors and other strongly correlated materials. Moreover, this anisotropy might be harnessed to enhance AF order. Here we numerically investigate, using Determinant Quantum Monte Carlo, a simple realization of anisotropy in the 3D Hubbard model in which the tunneling between planes, $t_\perp$, is unequal to the intraplane tunneling $t$. This model interpolates between the three-dimensional isotropic ($t_\perp = t$) and two-dimensional ($t_\perp =0$) systems. We show that at fixed interaction strength to tunneling ratio ($U/t$), anisotropy can enhance the magnetic structure factor relative to both 2D and 3D results. However, this enhancement occurs at interaction strengths below those for which the Néel temperature $T_{\rm N\acute{e}el}$ is largest, in such a way that the structure factor cannot be made to exceed its value in isotropic 3D systems at the optimal $U/t$. We characterize the 2D-3D crossover in terms of the magnetic structure factor, real space spin correlations, number of doubly-occupied sites, and thermodynamic observables. An interesting implication of our results stems from the entropy's dependence on anisotropy. As the system evolves from 3D to 2D, the entropy at a fixed temperature increases. Correspondingly, at fixed entropy, the temperature will decrease going from 3D to 2D. This suggests a cooling protocol in which the dimensionality is adiabatically changed from 3D to 2D.

description: The goal of this tutorial is to promote interest in the study of random Boolean networks (RBNs). These can be very interesting models, since one does not have to assume any functionality or particular connectivity of the networks to study their generic properties. Like this, RBNs have been used for exploring the configurations where life could emerge. The fact that RBNs are a generalization of cellular automata makes their research a very important topic. The tutorial, intended for a broad audience, presents the state of the art in RBNs, spanning over several lines of research carried out by different groups. We focus on research done within artificial life, as we cannot exhaust the abundant research done over the decades related to RBNs.

description: High resolution FUSE and STIS observations of the bright QSO HE 0226-4110 (zem = 0.495) reveal the presence of a multi-phase absorption line system at zabs(O VI) = 0.20701 containing absorption from H I (Ly alpha to Ly theta), C III, O III, O IV, O VI, N III, Ne VIII, Si III, S VI and possibly S V. Single component fits to the Ne VIII and O VI absorption doublets yield logN(Ne VIII) = 13.89+/-0.11 and logN(O VI) = 14.37+/-0.03. The Ne VIII and O VI doublets are detected at 3.9 sigma and 16 sigma significance levels, respectively. This represents the first detection of intergalactic Ne VIII, a diagnostic of gas with temperature in the range from 5x10(5) to 1x10(6) K. The O VI and Ne VIII are not likely created in a low density medium photoionized solely by the extragalactic background at z = 0.2 since the required path length of ~11 Mpc implies the Hubble flow absorption line broadening would be ~10 times greater than the observed line widths. A collisional ionization origin is therefore more likely. Assuming [Ne/H] and [O/H] = -0.5, the value N(Ne VIII)/N(O VI) = 0.33+/-0.10 is consistent with gas in collisional ionization equilibrium near T=5.4x10(5) K with logN(H)= 19.9 and N(H)/N(H I) = 1.7x10(6). The observations support the basic idea that a substantial fraction of the baryonic matter at low redshift exists in hot very highly ionized gaseous structures.

Spatiotemporal Calibration of Camera and 3D Laser Scanner

Subjects: subject: Robotics (cs.RO)
subject: FOS: Computer and information sciences

description: The multi-sensory setups consisting of the laser scanners and cameras are popular as the measurements complement each other and provide necessary robustness for applications. Under dynamic conditions or when in motion, a direct transformation (spatial calibration) and time offset between sensors (temporal calibration) is needed to determine the correspondence between measurements. We propose an open-source spatiotemporal calibration framework for a camera and a 3D laser scanner. Our solution is based on commonly available chessboard markers requiring one-minute calibration before the operation that offers accurate and repeatable results. The framework is based on batch optimization of point-to-plane constraints with a time offset calibration possible by a novel continuous representation of the plane equations based on a minimal representation in the Lie algebra and the use of B-splines. The framework's properties are evaluated in simulation while correctness is verified with two distinct sensory setups with Velodyne VLP-16 and SICK MRS6124 3D laser scanners.

description: We propose a class of actions for the spacetime metric that introduce corrections to the Einstein-Hilbert Lagrangian depending on the logarithm of some curvature scalars. We show that for some choices of these invariants the models are ghost free and modify Newtonian gravity below a characteristic acceleration scale given by a_0 = cμ, where c is the speed of light and μis a parameter of the model that also determines the late-time Hubble constant: H_0 \sim μ. In these models, besides the massless spin two graviton, there is a scalar excitation of the spacetime metric whose mass depends on the background curvature. This dependence is such that this scalar, although almost massless in vacuum, becomes massive and effectively decouples when one gets close to any source and we recover an acceptable weak field limit at short distances. There is also a (classical) ``running'' of Newton's constant with the distance to the sources and gravity is easily enhanced at large distances by a large ratio. We comment on the possibility of building a model with a MOND-like Newtonian limit that could explain the rotation curves of galaxies without introducing Dark Matter using this kind of actions. We also explore briefly the characteristic gravitational phenomenology that these models imply: besides a long distance modification of gravity they also predict deviations from Newton's law at short distances. This short distance scale depends on the local background curvature of spacetime, and we find that for experiments on the Earth surface it is of order \sim 0.1mm, while this distance would be bigger in space where the local curvature is significantly lower.

description: Hyper-parallel quantum information processing is a promising and beneficial research field. In this paper, we present a method to implement a hyper-parallel controlled-phase-flip (hyper-CPF) gate for frequency-, spatial-, and time-bin-encoded qubits by coupling flying photons to trapped nitrogen vacancy (NV) defect centers. The scheme, which differs from their conventional parallel counterparts, is specifically advantageous in decreasing against the dissipate noise, increasing the quantum channel capacity, and reducing the quantum resource overhead. The gate qubits with frequency, spatial, and time-bin degrees of freedom (DOF) are immune to quantum decoherence in optical fibers, whereas the polarization photons are easily disturbed by the ambient noise.

description: Human motion detection is getting considerable attention in the field of Artificial Intelligence (AI) driven healthcare systems. Human motion can be used to provide remote healthcare solutions for vulnerable people by identifying particular movements such as falls, gait and breathing disorders. This can allow people to live more independent lifestyles and still have the safety of being monitored if more direct care is needed. At present wearable devices can provide real time monitoring by deploying equipment on a person's body. However, putting devices on a person's body all the time make it uncomfortable and the elderly tends to forget it to wear as well in addition to the insecurity of being tracked all the time. This paper demonstrates how human motions can be detected in quasi-real-time scenario using a non-invasive method. Patterns in the wireless signals presents particular human body motions as each movement induces a unique change in the wireless medium. These changes can be used to identify particular body motions. This work produces a dataset that contains patterns of radio wave signals obtained using software defined radios (SDRs) to establish if a subject is standing up or sitting down as a test case. The dataset was used to create a machine learning model, which was used in a developed application to provide a quasi-real-time classification of standing or sitting state. The machine learning model was able to achieve 96.70 % accuracy using the Random Forest algorithm using 10 fold cross validation. A benchmark dataset of wearable devices was compared to the proposed dataset and results showed the proposed dataset to have similar accuracy of nearly 90 %. The machine learning models developed in this paper are tested for two activities but the developed system is designed and applicable for detecting and differentiating x number of activities.

description: This file contains modeling outputs generated using a modified version of the global aerosol-climate model ECHAM6.3-HAM2.3. The simulations focus on aerosols originating from biomass burning over the boreal region (>55°N) and cover both the current period (2000–2021) and future projections. The data provide annual summer (June–August) seasonal averages for each year within these periods. The future scenario simulations assume a global warming level of 1°C above present-day temperatures, which results in higher biomass burning emissions in the boreal region. These future simulations are driven by projected biomass burning emissions that remain constant, with meteorological fields nudged to the 2000-2020 period to account for the impacts of transport conditions.

The following aerosol-related variables are provided:

Image and voice in adult literacy

description: This qualitative research study explores the use of television as text in adult literacy as a means of bridging orality and literacy. The reason for selecting television as an educational tool was to provide equal access to stories for both non-readers and readers of print, and the 22 research participants were required to complete a survey and participate in four 2-hour workshops, and a taped interview. During the workshops, participants learned to actively engage with the texts that were edited stories from the Canadian television series North of 60. The researcher included reading strategies to encourage the participants' interaction with the texts as active "readers" (see Fiske, 1987; Buckingham, 1993; Bianculli, 1992) and brainstorming to increase their vocabulary prior to writing reflective responses. First, how television as text influences an adult literacy student's ability to transfer information from oral texts into print texts is analyzed. The findings indicate that television allows non-readers, reluctant readers, and delayed readers of English to learn literary terms and conventions that apply to print stories and practise four domains of language acquisition - listening, speaking, reading, and writing. A selection of each participant's written responses to the stories and interview fragments have been analyzed. Whenever possible, the selection is based on a participant's favorite story or personal connection to a character. Second, the effect of brainstorming on written responses has been examined. This technique is a pre-writing strategy the researcher used not only to assist the participants in recording vocabulary relevant to the story, but also to provide opportunities for sharing ideas in the construction of meaning. Based on data collected during the interviews, individuals with short-term memory problems indicate that repetition of vocabulary through brainstorming, note-taking, and discussion reinforces memory retention, and second language learners gain knowledge of pronunciation by hearing and rehearsing vocabulary from the stories. Third, factors contributing to the participants' reflective oral and written responses to the television stories have been analyzed. The main factors contributing to reflective thinking and writing involve the research pedagogy and the development of reflective skills through practice. The researcher's reflective methodology combines phenomenology, critical ethnography, and emancipatory practice from the diverse perspectives of van Manen (1990), Haig- Brown and Archibald (1996), and Freire (1974,1994,1997,1998) who have informed this study together with other researchers in the respective fields. This method situates the research participants and the researcher in a partnership in which everyone contributes through dialogue to the learning process.

description: In this paper, lattice simulations are used to propose a potential model for gluonic excited $Σ^-_u$ states of bottomonium meson . This proposed model is used to calculate radial wave functions, masses and radii of $Σ_u^-$ bottomonium hybrid mesons. Here, gluonic field between a quark and an antiquark is treated as in the Born-Oppenheimer expansion, and Schr$\ddot{o}$dinger equation is numerically solved employing shooting method. Results of calculated masses for $Σ^-_{u}$ state are in quite good agreement with the lattice simulations.

description: We evaluate the Brownian motion of a massive particle ("black hole") at the center of a galaxy using N-body simulations. Our galaxy models have power-law central density cusps like those observed at the centers of elliptical galaxies. The simulations show that the black hole achieves a steady-state kinetic energy that is substantially different than would be predicted based on the properties of the galaxy model in the absence of the black hole. The reason appears to be that the black hole responds to stars whose velocities have themselves been raised by the presence of the black hole. Over a wide range of density slopes and black hole masses, the black hole's mean kinetic energy is equal to what would be predicted under the assumption that it is in energy equipartition with stars lying within a distance ~r_h/2 from it, where r_h is the black hole's influence radius. The dependence of the Brownian velocity on black hole mass is approximately ~ 1/M^{1/(3-gamma)} with gamma the power-law index of the stellar density profile, rho~1/r^gamma. This is less steep than the 1/M dependence predicted in a model where the effect of the black hole on the stellar velocities is ignored. The influence of a stellar mass spectrum on the black hole's Brownian motion is also evaluated and found to be consistent with predictions from Chandrasekhar's theory. We use these results to derive a probability function for the mass of the Milky Way black hole based on a measurement of its proper motion velocity. Interesting constraints on M will require a velocity resolution exceeding 0.5 km/s.
