description: We examine the Pioneer anomaly - a reported anomalous acceleration affecting the Pioneer 10/11, Galileo and Ulysses spacecrafts - in the context of a braneworld scenario. We show that effects due to the radion field cannot account for the anomaly, but that a scalar field with an appropriate potential is able to explain the phenomena. Implications and features of our solution are analyzed.

description: The widespread diffusion of distributed energy resources, especially those based on renewable energy, and energy storage devices has deeply modified power systems. As a consequence, demand response, the ability of customers to respond to regulating signals, has moved from large high-voltage and medium-voltage end-users to small, low-voltage, customers. In order to be effective, the participation to demand response of such small players must be gathered by aggregators. The role and the business models of these new entities have been studied in literature from a variety of viewpoints. Demand response can be clearly applied by sending a dedicated price signal to customers, but this methodology cannot obtain a diverse, punctual, predictable, and reliable response. These characteristics can be achieved by directly controlling the loads units. This approach involves communication problems and technological readiness. This paper proposes a fully decentralized mixed integer linear programming approach for demand response. In this framework, each load unit performs an optimization, subject to technical and user-based constraints, and gives to the aggregator a desired profile along with a reserve, which is guaranteed to comply with the constraints. In this way, the aggregator can trade the reserve coming from several load units, being the only interface to the market. Upon request, then, the aggregator communicates to the load units the modifications to their desired profiles without either knowing or caring how this modification would be accomplished. The effectiveness is simulated on 200 realistic load units.

description: We investigate the connection between galaxy--galaxy mergers and enhanced black hole (BH) growth using the cosmological hydrodynamical EAGLE simulation. We do this via three methods of analysis, investigating: the merger fraction of AGN, the AGN fraction of merging systems and the AGN fraction of galaxies with close companions. In each case, we find an increased abundance of AGN within merging systems relative to control samples of inactive or isolated galaxies (by up to a factor of $\approx 3$ depending on the analysis method used), confirming that mergers are enhancing BH accretion rates for at least a subset of the galaxy population. The greatest excess of AGN triggered via a merger are found in lower mass ($M_* \sim 10^{10}$~\Msol) gas rich ($f_{\mathrm{gas}} > 0.2$) central galaxies with lower mass BHs ($M_{\mathrm{BH}} \sim 10^{7}$~\Msol) at lower redshifts ($z<1$). We find no enhancement of AGN triggered via mergers in more massive galaxies ($M_* \gtrsim 10^{11}$~\Msol). The enhancement of AGN is not uniform throughout the phases of a merger, and instead peaks within the early \emph{remnants} of merging systems (typically lagging $\approx 300$~Myr post-coalescence of the two galaxies at $z=0.5$). We argue that neither major ($M_{\mathrm{*,1}} / M_{\mathrm{*,2}} \geq \frac{1}{4}$) nor minor mergers ($\frac{1}{10} < M_{\mathrm{*,1}} / M_{\mathrm{*,2}} < \frac{1}{4}$) are statistically relevant for enhancing BH masses globally. Whilst at all redshifts the galaxies experiencing a merger have accretion rates that are on average 2--3 times that of isolated galaxies, the majority of mass that is accreted onto BHs occurs outside the periods of a merger. We compute that on average no more than 15\% of a BHs final day mass comes from the enhanced accretion rates triggered via a merger

Disease, Disability,and Desire: A Study of Select Western Romantic Films of 2010s
Creators: name: Chowdhury, Bikram
Publisher: name: Zenodo
Year: 2024

description: This research article talks about how disability is displayed in relation to disease and desire in film texts. It attempts to show how disease, disability, and desire interact with and influence one another in the lives of the patients characterized in the films titled The Fault in Our Stars (2014), Midnight Sun (2018), and Five Feet Apart (2019). By foregrounding that disability of living a normal social life is an integral component of disease for the patients in the physical level as well as the psychological level, the paper will explore how society has encoded normative behaviours of the patients, and in what ways the patients respond to this societal normativity when it comes to fulfilling of their desires. In Freudian terms, how the norms connected to disease and disability delineate the 'superego' of the patients, and how this superego aids in taming/or even honing their 'Id' and 'eros' for living life to the lees, will also be examined in this paper with substantial reference to the films mentioned above.

description: We give explicit analytic criteria for two problems associated with the Schrödinger operator $H = -Δ+ Q$ on $L^2(\R^n)$ where $Q\in D'(\R^n)$ is an arbitrary real- or complex-valued potential. First, we obtain necessary and sufficient conditions on $Q$ so that the quadratic form $$ has zero relative bound with respect to the Laplacian. For $Q\in L^1_{\rm loc}(\R^n)$, this property can be expressed in the form of the integral inequality: $$ | \int_{\R^n} |u(x)|^2 Q(x) dx | \leq ε||\nabla u||^2_{L^2(\R^n)} + C(ε) ||u||^2_{L^2(\R^n)}, \quad \forall u \in C^\infty_0(\R^n), $$ for an arbitrarily small $ε>0$ and some $C(ε)> 0$. Secondly, we characterize Trudinger's subordination property where $C(ε)$ in the above inequality is subject to the condition $C(ε) \le c {ε^{-β}}$ ($β>0$) as $ε\to +0$. Such quadratic form inequalities can be understood entirely in the framework of Morrey--Campanato spaces, using mean oscillations of $\nabla (1-Δ)^{-1} Q$ and $(1-Δ)^{-1} Q$ on balls or cubes. As a consequence, we characterize the class of those $Q$ which satisfy a multiplicative quadratic from inequality of Nash's type.

description: To determine the extent to which reduction of topographical organization of the olfactory system affects the ability to detect and discriminate different odors, rats with unilateral bulbectomy plus removal of approximately 24%-100% of the remaining glomeruli were tested using olfactometric methods on amyl acetate, butanol, citral, and propionic acid vapor detection tasks, to discriminate these odors from cineole, and to discriminate mixtures of odors. The lesions were measured by the linear extent of the remaining glomeruli and expressed as a percentage of control values (glomerular savings score). In 31 experimental rats glomerular savings scores ranged from 0% to 76%. Rats were grouped with regard to regional bulbar savings (major savings in the medial, lateral, or ventral areas of the bulb) and the amount of savings. Those with glomerular savings of less than 10% of the controls were anosmic (failed all detection tasks). Most rats with higher glomerular saving scores were able to perform all or most tasks at accuracy levels similar to those of unilateral bulbectomized controls although rats with large lesions (glomerular savings scores of 11-20%) made, on average, more errors than controls. Nevertheless, several rats with glomerular savings scores of 14%-20% performed as well as controls on most or all problems. Correlations between glomerular savings scores and various measures of odor detection and discrimination performance were relatively low ($-$0.23 to $-$0.43). There were few differences among groups with regard to regional glomerular savings scores and there was no clear evidence for a specific anosmia within any group or for any individual rat. Contrary to the prediction from topographical theories of odor coding that restricted areas of the bulb may be essential for mediating specific odors, the present results indicate that small regions of the olfactory bulb are capable of mediating a wide variety of odor detection and discrimination tasks. These outcomes are in accord with theories of odor coding which do not rely on a topographical correspondence between the olfactory neuroepithelium and the olfactory bulb.

description: The purpose of this paper is to address the problem of 'product innovations' (i.e. new goods, increased variety, and quality change) in the construction of price indices and, by extension, in the measurement of economic growth. The premise is that a great deal of technological progress takes indeed the form of product innovations, but conventional economic statistics fail by and large to reflect them. The approach suggested here consists of two stages: first, the benefits from product innovations are estimated with the aid of discrete-choice models, and second, those benefits are used to construct 'real' (or 'quality adjusted') price indices. Following a discussion of the merits of such approach vis a vis the use of hedonic price indices, I apply it to the study of a specific innovation, namely CT (Computed Tomography) Scanners. The main finding is that the rate of decline in the quality-adjusted price of CT scanners was a staggering 55% per year (on average) over the first decade following the invention of CT. By contrast, an hedonic-based 'real' index captures just a small fraction of the decline, and worse still, a simple (unadjusted) price index shows a substantial price Increase over the same period. Thus, conventional indices might be missing indeed a great deal of the welfare consequences of technical advance, particularly during the initial stages of the product cycle of new products. It remains to be seen, though, how much of the paradox of explosive technical change on the one hand, and 'low' measured growth rates on the other could be accounted for by this sort of discrepancies.

description: Nonlinear optics has long been a cornerstone of modern photonic technology, enabling a wide array of applications, from frequency conversion to the generation of ultrafast light pulses. Recent breakthroughs in two-dimensional (2D) materials have opened a frontier in this field, offering new opportunities for both classical and quantum nonlinear optics. These atomically thin materials exhibit strong light-matter interactions and large nonlinear responses, thanks to their tunable lattice symmetries, strong resonance effects, and highly engineerable band structures. In this paper, we explore the potential that 2D materials bring to nonlinear optics, covering topics from classical nonlinear optics to nonlinearities at the few-photon level. We delve into how these materials enable possibilities, such as symmetry control, phase matching, and integration into photonic circuits. The fusion of 2D materials with nonlinear optics provides insights into the fundamental behaviors of elementary excitations such as electrons, excitons, and photons in low dimensional systems and has the potential to transform the landscape of next-generation photonic and quantum technologies.

description: The renormalization of conductances in a Y junction of spinless Luttinger-liquid wires additionally coupled to acoustic longitudinal phonons is investigated in fermionic representation. This system corresponds to geometry of a tunneling experiment and exhibits the interplay between the Coulomb repulsion and the attractive retarded interaction mediated by phonons. The retardation effects related to the propagation of phonons through the junction with arbitrary transmission and reflection amplitudes are taken into account. The appearing logarithmic corrections to conductances of the junction are treated in a renormalization group approach, and scaling exponents are calculated up to infinite order in the interaction after RPA-type summation. The fixed points and corresponding scaling exponents are considered in various non-equilibrium regimes. We show that the boundary exponent and the bulk anomalous dimension of fermion operator are characterized by two different Luttinger parameters, referring to the main wire, thanks to non-local character of phonon-mediated interaction. In the limiting case of the junction of only two wires, the scaling exponents found by our method are in exact correspondence with previous bosonization analysis.

description: University students often struggle with financial hardships. Yet, UBC enrolment services professionals report strikingly low student attendance rates for their financial education programs. One factor that may influence attendance rates for students with high financial stress is how receptive they are to advertisements promoting these programs. It is possible that for students under considerable financial distress, advertisements that provide emotional support may be more appealing and increase the likelihood that students will attend a workshop in the future. To test this, we recruited 140 UBC students to read one of two different advertisements: the current informational support-based advertisement or a modified emotional support-based version of the advertisement. Afterward, participants rated how appealing they found the message and how likely they would attend a financial workshop after reading the message. For students under high financial stress, there were no differences in message appeal. However, these same financially stressed students reported a greater likelihood of attending a workshop after reading the emotional support-based advertisement as compared to the current, informational support-based advertisement. Our study emphasizes the importance of conveying emotional support to students with high financial stress to help increase the likelihood that students’ will access financial services at UBC.

description: The structure-hepatic CYP2B-inducing activity relationships within structural congeners of the prototype CYP2B-type inducing agent, phenobarbital, were systematically evaluated in the rat. A number of congeners were fed to rats for two weeks at dietary concentrations equimolar to 500 ppm phenobarbital. At the conclusion of these experiments, liver post-mitochondrial supernatants (S-9s) were prepared and examined for catalytic activity toward the CYP2B-specific substrates benzyloxy- and pentoxyresorufin. In addition, the relative levels of hepatocellular CYP2B1 and CYP2B1/2B2 protein were determined by immunodetection with monoclonal antibodies. Based upon the results obtained, certain of the congeners were selected for pharmacodynamic studies. These experiments involved dose-response studies in which the measured increases in in vitro catalytic activities, immunoreactive protein, and, for selected congeners, RNAs coding for CYP2B1 or CYP2B2, were related to serum concentrations of the congeners. Sigmoid serum concentration-CYP2B induction response curves were obtained for many of the congeners, which is suggestive of receptor mediation. Profound differences in potency and efficacy for this effect among the series of congeners were also identified. In addition, sex differences in potency of CYP2B induction were demonstrated for phenobarbital. Such differences in potency may relate to differences in the efficacy or affinity of these congeners at a specific receptor. However, no enantioselectivity for CYP2B induction in the F344/NCr rat was identified in examination of the CYP2B inducing abilities of 5-ethyl-5-phenylhydantoin and its two enantiomers. Although to date, no receptor for the induction of CYP2B1 activity has been demonstrated, the present studies have the potential of providing evidence for or against receptor-mediation in this phenomenon.

description: The results of kinetic simulations of magnetic reconnection in Harris current sheets are analyzed. A range of guide fields is considered to study reconnection in plasmas characterized by different $β$ values, $β> m_e/m_i$. Both an implicit Particle-in-Cell (PIC) simulation method and a parallel explicit PIC code are used. Simulations with mass ratios up to the physical value are performed. The simulations show that the reconnection rate decreases with the guide field and depends weakly on the mass ratio. The off-diagonal components of the electron pressure tensor break the frozen-in condition, even in low $β$ plasmas. In high $β$ plasmas, evidence is presented that whistler waves play a key role in the enhanced reconnection, while in low $β$ plasmas the kinetic Alfvén waves are important. The in-plane and the out-of-plane ion and electron motion are also considered, showing that they are influenced by the mass ratio and the plasma $β$.

description: Integral field optical spectroscopy with the INTEGRAL system has been used to investigate for the first time the two-dimensional kinematic and ionization properties of the extended, warm ionized gas in Arp 220 over an area of 28 kpc by 15 kpc. The structure of the ionized gas is divided into well identified regions associated with the X-ray emitting plumes and extended lobes. Changes in the ionization state of the gas along the major axis of the plumes are detected, in particular in the outer regions of the northwestern plume where the transition between the main stellar body of the galaxy and a broad, low surface brightness tidal tail is located. If the plumes are produced by a starburst-driven galactic wind, the efficiency in the conversion of mechanical to radiation energy is a factor of at least 10 smaller than in galactic winds developed in edge-on spirals with well defined rotation and outflowing axis. The kinematic properties of the lobes are to a first order in agreement with the predictions of the merger scenario according to which the lobes are tidal-induced gas condensations produced during the merging process. The largest velocity gradients and velocity deviations from the systemic velocity are not associated with the plumes, but with the outer stellar envelope and broad tidal tails at distances of up to 7.5 kpc, indicating that the large scale kinematics of the extended ionized gas in Arp 220, is most likely dominated by the tidal-induced motions, and not by galactic winds associated with nuclear starbursts.

description: В статье рассматривается ситуация, которая может сложиться после введения Евросоюзом с 2021 года пограничного углеродного налога на импорт, являющегося частью мировой климатической политики по снижению выбросов СО . По мнению авторов, Россия не готова к столь быстрому введению такого налога и страна может потерять от 3,5-6 миллиардов евро (на начальных этапах) до 50,6 миллиарда к 2030 году. Магистральными мерами смягчения таких последствий должно стать принятие единых государственных методик расчета поглотительной способности лесов и углеродного следа, ускоренное формирование углеродного рынка с возможностью продажи лесных проектов и принятие адресной стратегии низкоуглеродного развития экономики России.

description: We study the effects of the coupling to an Ohmic quantum reservoir on the static and dynamical properties of a family of disordered SU(2) spin models in a transverse magnetic field using a method of direct spin summation. The tendency to form a glassy phase increases with the strength of the coupling of the system to the environment. We study the influence of the environment on the features of the phase diagram of the various models as well as the stability of the possible phases.

title: How Children with Dyslexia Experience School: Developing an Instrument to Measure Coping, Self-Esteem and Depression
Creators: name: Alexander-Passe, Neil
Publisher: name: The Open University
Year: 2004

description: Dyslexia is a widespread condition amongst children, teenagers and adults, with one dyslexic child estimated to be in each mainstream school classroom. Although there is no known cure, there are several different ways that children with dyslexia can be helped to reach their potential. However, such children are often not correctly identified and therefore do not receive the help they need.

 Schools in particular often do not have funds available for assessment, or are unable to afford the specialist teachers the children need. In addition, some teachers do not recognise the existence of dyslexia and see it as the reason middle-class parents give for their child not under achieving. So, instead of helping, they ignore or humiliate the child, with disastrous consequences. It falls to parents to get the help needed from schools, or to look elsewhere for assistance. A questionnaire to support parents in doing so has been developed in this study.

The questionnaire has undergone nine stages of development, and three stages of evaluation.

The questionnaire contains just 12 items. However, it enables parents to assess and discuss whether their child with known or suspected dyslexia is under stress, and how much ‘Trying’ or ‘Blaming’ their child is using to cope with it.

When a child shows considerable use of the Blaming response, significant depression and loss of self-esteem can be inferred, so parents can ask as a matter of urgency that their child be given appropriate emotional and practical support.

description: The problem. The purpose of this study was to re-examine the reading improvement programs of the 92 colleges and universities in the United States that Leedy examined in the 1950s to (a) determine if reading programs of the 1990s are as much a part of universities' commitment to meet the needs of all students enrolled as they appeared to be in the 1950s; (b) discern if teaching methods and materials to accommodate the needs of students of various nationalities, cultures, and educational backgrounds and capabilities have changed; (c) ascertain if reading programs of the 1990s have become more consistent in terms of instructional theories, methods, materials, and diagnostic and evaluative testing procedures; and (d) identify other types of reading programs in addition to remedial reading programs. The results. There were no significant differences in the reading programs of 1958 and 1992 in the following areas: sponsors of reading programs; ability to accept referrals; average number of class sessions per week; average length (clock hours) of an entire course; effectiveness; production of own teaching materials; clerical and administrative staff sizes; total number of staff people in the entire program; preference for instructors with advanced academic degrees and specialized qualifications; and budget allocations for salaries, supplies, and maintenance. Data did not support the null hypothesis and indicated there were significant differences in the following areas: conditions for reading instruction; enrollment in the entire program; allowance of academic credit for course work; class time allotted for timed, silent reading and use of reading films and machines; informal testing procedures and types of tests used; emphasis on some instructional activities; teacher to student ratio; budget--there is more money available in the 1992 budgets. The conclusions. The status of reading programs in 1992 is much the same as it was in 1958. Although very little has changed in the reading improvement programs that were investigated, the changes that did occur were significant. In the curricula, there has been a de-emphasis on reading speed as an instructional activity while greater emphasis has been placed on reading in the content areas and writing and listening skills as integral parts of reading instruction. Fewer reading machines of the types described in Leedy's study are used. Instead, the computer and television are the mechanical aids most likely used. (Abstract shortened by UMI.).

description: By analytically continuing recently-found instantons, we construct time-dependent solutions of Einstein-Maxwell de Sitter gravity which smoothly bounce between two de Sitter phases. These deformations of de Sitter space undergo several stages in their time evolution. Four and five-dimensional de Sitter bounces can be lifted to non-singular time-dependent solutions of M-theory.

description: We analytically compute the three-loop corrections to the relation between the renormalized quark masses defined in the minimal-subtraction (${\rm \overline{MS}}$) and the regularization-invariant symmetric momentum-subtraction (${\rm RI/SMOM}$) schemes. Our result is valid in the Landau gauge and can be used to reduce the uncertainty in a lattice determination of the ${\rm \overline{MS}}$ quark masses.

Logarithmic Relaxation in a Colloidal System

description: The slow dynamics for a colloidal suspension of particles interacting with a hard-core repulsion complemented by a short-ranged attraction is discussed within the frame of mode-coupling theory for ideal glass transitions for parameter points near a higher-order glass-transition singularity. The solutions of the equations of motion for the density correlation functions are solved for the square-well system in quantitative detail by asymptotic expansion using the distance of the three control parameters packing fraction, attraction strength and attraction range from their critical values as small parameters. For given wave vectors, distinguished surfaces in parameter space are identified where the next-to-leading order contributions for the expansion vanish so that the decay functions exhibit a logarithmic decay over large time intervals. For both coherent and tagged particle dynamics the leading-order logarithmic decay is accessible in the liquid regime for wave vectors of several times the principal peak in the structure factor. The logarithmic decay in the correlation function is manifested in the mean-squared displacement as a subdiffusive power law with an exponent varying sensitively with the control parameters. Shifting parameters through the distinguished surfaces, the correlation functions and the logarithm of the mean-squared displacement considered as functions of the logarithm of the time exhibit a crossover from concave to convex behavior, and a similar scenario is obtained when varying the wave vector.

description: Multimodal MR images can provide complementary information for accurate brain tumor segmentation. However, it's common to have missing imaging modalities in clinical practice. Since there exists a strong correlation between multi modalities, a novel correlation representation block is proposed to specially discover the latent multi-source correlation. Thanks to the obtained correlation representation, the segmentation becomes more robust in the case of missing modalities. The model parameter estimation module first maps the individual representation produced by each encoder to obtain independent parameters, then, under these parameters, the correlation expression module transforms all the individual representations to form a latent multi-source correlation representation. Finally, the correlation representations across modalities are fused via the attention mechanism into a shared representation to emphasize the most important features for segmentation. We evaluate our model on BraTS 2018 datasets, it outperforms the current state-of-the-art method and produces robust results when one or more modalities are missing.

description: We present a simple introduction to the decision tree algorithm using some examples from nuclear physics. We show how to improve the accuracy of the classical liquid drop nuclear mass model by performing Feature Engineering with a decision tree. Finally, we apply the method to the Duflo-Zuker model showing that, despite their simplicity, decision trees are capable of improving the description of nuclear masses using a limited number of free parameters.
