description: The Airy structure in $^{16}$O+$^{14}$C rainbow scattering is studied with an extended double folding (EDF) model that describes all the diagonal and off-diagonal coupling potentials derived from the microscopic realistic wave functions for $^{16}$O using a density-dependent nucleon-nucleon force. The experimental angular distributions at $E_L$=132, 281 and 382.2 MeV are well reproduced by the calculations. By studying the energy evolution of the Airy structure, the Airy minimum at around $θ$=76$^\circ$ in the angular distribution at $E_L$=132 MeV is assigned as the second order Airy minimum $A2$ in contrast to the recent literature which assigns it as the third order $A3$. The Airy minima in the 90$^\circ$ excitation function is investigated in comparison with well-known $^{16}$O+$^{16}$O and $^{12}$C+$^{12}$C systems. Evolution of the Airy structure into the molecular resonances with the $^{16}$O+$^{14}$C cluster structure in the low energy region around $E_{c.m.}$=30 MeV is discussed. It is predicted theoretically for the first time for a non-$4N$ $^{16}$O+$^{14}$C system that Airy elephants in the 90$^\circ$ excitation function are present.

description: Realizing systems that support robust, controlled interactions between individual photons is an exciting frontier of nonlinear optics. To this end, one approach that has emerged recently is to leverage atomic interactions to create strong and spatially non-local interactions between photons. In particular, effective interactions have been successfully created via interactions between atoms excited to Rydberg levels. Here, we investigate an alternative approach, in which atomic interactions arise via their common coupling to photonic crystal waveguides. This technique takes advantage of the ability to separately tailor the strength and range of interactions via the dispersion engineering of the structure itself, which can lead to qualitatively new types of phenomena. As an example, we discuss the formation of correlated transparency windows, in which photonic states of a certain number and shape selectively propagate through the system. Through this technique, we show in particular that one can create molecular-like potentials that lead to molecular bound states of photon pairs.

description: A canonical quantization scheme applied to a classical supersymmetric system with quadratic in momentum supercharges gives rise to a quantum anomaly problem described by a specific term to be quadratic in Planck constant. We reveal a close relationship between the anomaly and the Schwarzian derivative, and specify a quantization prescription which generates the anomaly-free supersymmetric quantum system with second order supercharges. We also discuss the phenomenon of a coupling-constant metarmorphosis that associates quantum systems with first-order supersymmetry to the systems with the second-order supercharges.

description: In superconductors spin-split by an exchange field, thermal effects are coupled to spin transport. We show how an oscillating electromagnetic field in such systems creates spin imbalance, that can be detected with a spin-polarized probe. The sign and magnitude of the probe signal result from a competition between processes converting field induced spin energy imbalance to spin imbalance, dominant at low frequencies, and microwave-driven pair breaking at high frequencies. In the presence of spin-flip scattering, we show that ac excitation also leads to multistabilities in the superconducting state.

Subjects: Retro products, purchase motivations, consumer segmentation

description: This paper studies the potential market for consumers of retro products. A review of the literature on the topic was carried out, enabling the motivations taken into account in the selection of such goods to be defined. An individual survey of 258 consumers was conducted. Factor analysis enabled us to determine the three main dimensions in the purchase of retro products: “Present Feelings of Distinctiveness”, “Product Characteristics” and “Past Feelings”. Cluster analysis performed using these dimensions enabled the identification of two clearly differentiated segments. It should be noted that the largest segment, containing nearly three out of every four potential consumers, displays the strongest intention of buying retro products in the categories of food, cars and technology products.

description: Hospitals are known as functionally complex buildings in various ways, namely due to their non-trivial spatial connectivity requirements. A spatial configuration has an impact on human behavior, human movement patterns and should match with the operational logic of the buildings. In hospitals, there are several typical problems that can be attributed to the configuration of the building, namely the inefficient circulation of medical staff, difficult way-finding for visitors, lengthy and complex procedures for patients, long walking times, privacy, hygiene issues and so on. This Ph.D. research aims to develop a computational design methodology for configurational layout optimization of hospital buildings concerning physical matters & human factors, which are directly attributable to the layout/configuration of the hospital. In the optimization models, the considered performance indicators are related with patients (e.g. ease of way-finding), staff (e.g. average walking-time), and operations (e.g. fitness for workflows). Two case studies are studied here as (1) reconfiguration of existing hospitals; and (2) designing the new hospitals by focussing on “layout planning” and “corridor design”. The developed models are programmed in the form of design tool-kits for supporting conceptual design phases. Effectively, this project presents an interdisciplinary methodological framework that can tackle hospital layout design problems by integrating Computational Design workflows, Graph Theory techniques, Operations Research, and Computational Intelligence into the field of Architectural Space Planning.

description: It is discovered that the tokamak field geometry generates a pitch-angle scattering effect for runaway electrons. This neoclassical pitch-angle scattering is much stronger than the collisional scattering and invalidates the gyro-center model for runaway electrons. As a result, the energy limit of runaway electrons is found to be larger than the prediction of the gyro-center model and to depend heavily on the background magnetic field.
Probabilistic approach to residential vapor intrusion exposure screening for Chlorinated Volatile Organic Compounds: a case study in San Antonio,Texas
Creators: name: Johnston, Jill E.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: The potential for subsurface volatile chemicals to migrate through the soil and impact indoor air quality is an increasingly important exposure pathway at contaminated sites. The characterization of this pathway is highly uncertain and dependent upon many site and building-specific parameters. A probability house-by-house model, based on the Johnson-Ettinger algorithm, is developed based on the current and historic conditions of groundwater contamination of tricholorethylene and tetrachlorethylene from activities at the former Kelly Air Force Base in San Antonio, Texas. The analysis suggests that historically 5.5% of houses exceed PCE screening levels (0.41 ug/m3) at the mean level and 85.3% at the 95th percentile; for TCE (at 0.25 ug/m3) it is 49% and 99% respectively. The current EPA model is slightly less conservative than the new parameterization by Johnson (2005). Comparison with measured samples suggests the probabilistic model underestimates exposure. Soil properties and air exchange rates are the most input critical parameters.
Massive Warm/Hot Galaxy Coronae as Probed by UV/X-ray Oxygen Absorption and Emission: I - Basic Model

description: We construct an analytic phenomenological model for extended warm/hot gaseous coronae of $L_*$ galaxies. We consider UV OVI COS-Halos absorption line data in combination with Milky Way X-ray OVII and OVIII absorption and emission. We fit these data with a single model representing the COS-Halos galaxies and a Galactic corona. Our model is multi-phased, with hot and warm gas components, each with a (turbulent) log-normal distribution of temperatures and densities. The hot gas, traced by the X-ray absorption and emission, is in hydrostatic equilibrium in a Milky Way gravitational potential. The median temperature of the hot gas is $1.5 \times 10^6$~K and the mean hydrogen density is $\sim 5 \times 10^{-5}~{\rm cm^{-3}}$. The warm component as traced by the OVI, is gas that has cooled out of the high density tail of the hot component. The total warm/hot gas mass is high and is $1.2 \times 10^{11}~{\rm M_{\odot}}$. The gas metallicity we require to reproduce the oxygen ion column densities is $0.5$ solar. The warm OVI component has a short cooling time ($\sim 2 \times 10^8$ years), as hinted by observations. The hot component, however, is $\sim 80\%$ of the total gas mass and is relatively long-lived, with $t_{cool} \sim 7 \times 10^{9}$ years. Our model supports suggestions that hot galactic coronae can contain significant amounts of gas. These reservoirs may enable galaxies to continue forming stars steadily for long periods of time and account for "missing baryons" in galaxies in the local universe.

A  Synthetic Indicator Method Applied to Putnam’s Social Capital Indicators: The Case of Italy

Subjects: regional social capital; synthetic indicator; Putnam

description: In his 1993 book titled Making Democracy Work, R. D. Putnam (1993) paved the way for many studies on the distribution of social capital in the different Italian regions. Moreover, he introduced the use of some ‘specific’ indicators to measure social capital considered as civicness, which have ‘systematically’ been adopted in subsequent investigations. In the present essay, the synthetic indicator method, which was designed by Pena (1977; 2009), was applied to the data collected by other scholars (specifically, Cartocci, 2007; Bordandini, Cartocci, 2014; Vanelli, Cartocci, 2015) who replicated Putnam’s research (1993), in order to create a synthetic indicator of social capital. This ‘methodological experiment’ confirms that, in the northern part of Italy, civicness is more widespread than in the South. Furthermore, it proves that voluntary activities and blood donation actions have a major impact on social capital indicators.

description: Advances in cognitive radio networks have primarily focused on the design of spectrally agile radios and novel spectrum sharing techniques that are founded on Expected Utility Theory (EUT). In this paper, we consider the development of novel spectrum sharing algorithms in such networks taking into account human psychological behavior of the end-users, which often deviates from EUT. Specifically, we consider the impact of end-user decision making on pricing and management of radio resources in a cognitive radio enabled network when there is uncertainty in the Quality of Service (QoS) guarantees offered by the Service Provider (SP). Using Prospect Theory (a Nobel-Prize-winning behavioral economic theory that captures human decision making and its deviation from EUT), we design data pricing and channel allocation algorithms for use in cognitive radio networks by formulating a game theoretic analysis of the interplay between the price offerings, bandwidth allocation by the SP and the service choices made by end-users. We show that, when the end-users under-weight the service guarantee, they tend to reject the offer which results in under-utilization of radio resources and revenue loss. We propose prospect pricing, a pricing mechanism that can make the system robust to decision making and improve radio resource management. We present analytical results as well as preliminary human subject studies with video QoS.

description: The impact of the climate on the health of populations is now reaching the mainstream. The impact of health system decisions on the lives of its patients has been studied through several analyses and research projects that identified direct, unequivocal links between healthcare services and the effect on healthcare demand of those same services. The UK NHS contributes the equivalent of 24 million tonnes of CO2 greenhouse gases to the climate footprint of the UK. This is 5.4% of the entire UK’s Carbon footprint and is a value bigger than 2.8 million UK households or the entire emissions of the countries of Jordan, Croatia and Estonia. It is the UK’s biggest single emitter of CO2 and consumer of single use plastics. Directly contributing to the deaths of 40,000 people through respiratory disorders, 900 through heatstroke at a cost of almost £400 million annually. The majority of the NHS carbon footprint (19 million tonnes of CO2) come through the NHS supply chain with only 5.5 million tonnes resulting from internal activity. Suggesting the biggest impact will be driven through changes to procurement. Procurement currently assigns a range of importance to health and economic factors. Most procurement is conducted with an asymmetric split of quality and cost. 80:20, 70:30 or 60:40 ratios of quality and cost, while the NHS evaluates the evidence base by using Quality Adjusted Life Years and Disability Adjusted Life Years, both of which evaluate the gain the technology provides, but does not include the impacts downstream of the patient, which result in this emissions footprint that in turn appears as A&E and healthcare demand. Together, these factors suggest current deployed health-economic models are not sufficient to catch the failure demand nor assess the lifecycle impact of climate effects on the service itself, via the population. This paper explores an alternative model that accounts for the impact of climate on the health-economic models and constructs an evaluation framework for supplier assessment.
Re-thinking Populism within the Borders of Democracy

Year: 2018
Subjects: Populism, populist logic, populist politics.

description: Although populism has many references and various definitions as an elusive and ambiguous concept, this article approaches it as a political project which has a potential to undermine democracy in some ways. This approach enables a broader comprehension of populism rather than confining it to some ideological tenets or a few undisputed populist movements. In the study, it is attempted to reveal the logic of this political project through a tripartite analysis which consists of the sense of democracy inherent in populism, its way of thinking and reasoning, and the political circumstances which enables and strengthens populism. It is argued that the analysis performed here can offer an outline of the ground on which the struggle against the features of populism, that threatens democracy, can be carried out. Finally, in the light of the aforementioned analysis and some ideas which are borrowed from the works of Habermas and Mouffe to a large extent and discussed in an interconnected manner, it is aimed to re-read democracy as an answer to problems arising out of populism.

description: Quasar emission lines are often shifted from the systemic velocity due to various dynamical and radiative processes in the line-emitting region. The level of these velocity shifts depends both on the line species and on quasar properties. We study velocity shifts for the line peaks of various narrow and broad quasar emission lines relative to systemic using a sample of 849 quasars from the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) project. The coadded (from 32 epochs) spectra of individual quasars have sufficient signal-to-noise ratio (SNR) to measure stellar absorption lines to provide reliable systemic velocity estimates, as well as weak narrow emission lines. The sample also covers a large dynamic range in quasar luminosity (~2 dex), allowing us to explore potential luminosity dependence of the velocity shifts. We derive average line peak velocity shifts as a function of quasar luminosity for different lines, and quantify their intrinsic scatter. We further quantify how well the peak velocity can be measured for various lines as a function of continuum SNR, and demonstrate there is no systematic bias in the line peak measurements when the spectral quality is degraded to as low as SNR~3 per SDSS pixel. Based on the observed line shifts, we provide empirical guidelines on redshift estimation from [OII]3728, [OIII]5008, [NeV]3426, MgII, CIII], HeII1640, broad Hbeta, CIV, and SiIV, which are calibrated to provide unbiased systemic redshifts in the mean, but with increasing intrinsic uncertainties of 46, 56, 119, 205, 233, 242, 400, 415, and 477 km/s, in addition to the measurement uncertainties. These more realistic redshift uncertainties are generally much larger than the formal uncertainties reported by the redshift pipelines for spectroscopic quasar surveys, and demonstrate the infeasibility of measuring quasar redshifts to better than ~200 km/s with only broad lines.

description: The present study is an attempt to shed light on the mediator-learner’s interaction in the development of listening comprehension skill and compare this interaction between high and low proficient L2 learners of English. 30 L2 learners participated in Oxford’s Quick Placemat Test and the Interactions/Mosaic Listening Placement Test to select those whose proficiency levels and listening skills were based on the placement guide of the tests, at upper-intermediate and advanced levels. Out of 30 students, 12 learners (advanced level=6, upper-intermediate=6) volunteered to participate in individualized tutoring sessions. Learners listened to the listening items and answered the item(s) individually. Upon the learner’s failure to answer the item, the mediator intervened and provided mediation. Mediation was provided using the interactionist approach. The qualitative data were then coded in terms of task completion along with errors and struggles to indicate the quantity and quality of mediation happened throughout the Dynamic Assessment (DA) intervention. Qualitative comparisons were made between the two ability levels on the type of mediation required at these two ability levels. Quantitative comparisons were made to find out learners’ Zone of Actual Development (ZAD), Zone of Proximal Development (ZPD), Gain Score (GS), and Learning Potential Score (LPS). Findings of the study revealed that DA mediation resulted in the development of the listening comprehension ability of advanced and upper-intermediate learners. The ability level of the learners was not, however, a determining factor in enhancing the development of the listening comprehension ability of learners at two ability levels. A close qualitative analysis of all the mediated interactions revealed that twenty-five mediational strategies were identified that promoted the development of listening abilities of advanced and upper-intermediate level learners. It is also revealed that the upper-intermediate learners required more mediational support as compared to the advanced learners.

title: Women's unemployment; a domestic occupation: A reconsideration of women's employment, unemployment and domesticity
Creators: name: Evans, Frances B.
Publisher: name: University of Kent
Year: 2023

description: This thesis explores women's unemployment through an analysis of their paid and unpaid work. It is suggested that sociological writing about unemployment has been dominated by accounts of male experience, and a specific consideration of the meaning of unemployment for women is presented here. A blend of research methodologies has been developed, using the work of feminists, life historians and interactionists. This distinctive, qualitative approach produces empirical data about many aspects of the lives of a group of middle-aged women, in which to situate their experiences of work of all kinds. Before presenting an analysis of these data, the period through which the women have lived is discussed, in order to understand the broader social context of their lives. This account draws on the published work of both historians and sociologists, identifying the social trends and events which may have been of particular relevance to women, as well as the range of influences on such developments. The empirical part of the research which is reported on here produced two types of findings. The first deals with the patterns of women's paid employment over the life-cycle, while the second relates to women's attitudes to domestic labour. Both make clear the links between domestic and paid work. A wide range of published material from the seventeenth, nineteenth and twentieth centuries is then used to develop an understanding of the contemporary form of domestic labour. Particular attention is paid in this analysis to the ways in which ideological and material influences mould the historically specific meaning and practice of domestic labour. In conclusion, the findings which are presented in this thesis are discussed in the context of other recently published work which addresses the analysis of women's unemployment.

description: The Hydrogen Epoch of Reionization Array (HERA) is a radio interferometer aiming to detect the power spectrum of 21 cm fluctuations from neutral hydrogen from the Epoch of Reionization (EOR). Drawing on lessons from the Murchison Widefield Array (MWA) and the Precision Array for Probing the Epoch of Reionization (PAPER), HERA is a hexagonal array of large (14 m diameter) dishes with suspended dipole feeds. Not only does the dish determine overall sensitivity, it affects the observed frequency structure of foregrounds in the interferometer. This is the first of a series of four papers characterizing the frequency and angular response of the dish with simulations and measurements. We focus in this paper on the angular response (i.e., power pattern), which sets the relative weighting between sky regions of high and low delay, and thus, apparent source frequency structure. We measure the angular response at 137 MHz using the ORBCOMM beam mapping system of Neben et al. We measure a collecting area of 93 m^2 in the optimal dish/feed configuration, implying HERA-320 should detect the EOR power spectrum at z~9 with a signal-to-noise ratio of 12.7 using a foreground avoidance approach with a single season of observations, and 74.3 using a foreground subtraction approach. Lastly we study the impact of these beam measurements on the distribution of foregrounds in Fourier space.

description: We characterize the performance of the widely-used least-squares estimator in astrometry in terms of a comparison with the Cramer-Rao lower variance bound. In this inference context the performance of the least-squares estimator does not offer a closed-form expression, but a new result is presented (Theorem 1) where both the bias and the mean-square-error of the least-squares estimator are bounded and approximated analytically, in the latter case in terms of a nominal value and an interval around it. From the predicted nominal value we analyze how efficient is the least-squares estimator in comparison with the minimum variance Cramer-Rao bound. Based on our results, we show that, for the high signal-to-noise ratio regime, the performance of the least-squares estimator is significantly poorer than the Cramer-Rao bound, and we characterize this gap analytically. On the positive side, we show that for the challenging low signal-to-noise regime (attributed to either a weak astronomical signal or a noise-dominated condition) the least-squares estimator is near optimal, as its performance asymptotically approaches the Cramer-Rao bound. However, we also demonstrate that, in general, there is no unbiased estimator for the astrometric position that can precisely reach the Cramer-Rao bound. We validate our theoretical analysis through simulated digital-detector observations under typical observing conditions. We show that the nominal value for the mean-square-error of the least-squares estimator (obtained from our theorem) can be used as a benchmark indicator of the expected statistical performance of the least-squares method under a wide range of conditions. Our results are valid for an idealized linear (one-dimensional) array detector where intra-pixel response changes are neglected, and where flat-fielding is achieved with very high accuracy.

Adoption and Implementation of Preventive Dentistry Initiatives for Physicians: A National Survey of Medicaid Programs
Creators: name: Sams, Lattice Deaver.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: The objectives of this study are to: 1) identify Medicaid programs with initiatives in which non-dental primary care health clinicians provide preventive dental services for children; and 2) determine Medicaid dental directors' perceptions of the attributes of these preventive dental initiatives. A cross-sectional, web-based survey using QualtricsTM online survey software was administered to all state dental program managers. The survey included 50 items in 7 domains. Descriptive statistics were produced using QualtricsTM. An analysis of the primary hypothesis that tested the effect of initiative attributes on adoption was based on Roger's diffusion of innovation theory. Delivery of preventive dental services by physicians in Medicaid programs is becoming widespread in the United States. Adoption is affected more by perceived relative advantage of the innovation (e.g., the program is effective in improving access) than other attributes.

description: A conceptual mechanism of amplification of phonons by phonons on the basis of nonlinear band-gap transmission (supratransmission) phenomenon is presented. As an example a system of weakly coupled chains of anharmonic oscillators is considered. One (source) chain is driven harmonically by boundary with a frequency located in the upper band close to the band edge of the ladder system. Amplification happens when a second (gate) chain is driven by a small signal in the counter phase and with the same frequency as first chain. If the total driving of both chains overcomes the band-gap transmission threshold the large amplitude band-gap soliton emerges and amplification scenario is realized. The mechanism is interpreted as nonlinear superposition of evanescent and propagating nonlinear modes manifesting in a single or double soliton generation working in band-gap or band-pass regimes, respectively. The results could be straightforwardly generalized for all-optical or all-magnonic contexts and has all the promises for logic gate operations.

description: The Economic Complexity Index (ECI; Hidalgo & Hausmann, 2009) measures the complexity of national economies in terms of product groups. Analogously to ECI, a Patent Complexity Index (PatCI) can be developed on the basis of a matrix of nations versus patent classes. Using linear algebra, the three dimensions: countries, product groups, and patent classes can be combined into a measure of "Triple Helix" complexity (THCI) including the trilateral interaction terms between knowledge production, wealth generation, and (national) control. THCI can be expected to capture the extent of systems integration between the global dynamics of markets (ECI) and technologies (PatCI) in each national system of innovation. We measure ECI, PatCI, and THCI during the period 2000-2014 for the 34 OECD member states, the BRICS countries, and a group of emerging and affiliated economies (Argentina, Hong Kong, Indonesia, Malaysia, Romania, and Singapore). The three complexity indicators are correlated between themselves; but the correlations with GDP per capita are virtually absent. Of the world's major economies, Japan scores highest on all three indicators, while China has been increasingly successful in combining economic and technological complexity. We could not reproduce the correlation between ECI and average income that has been central to the argument about the fruitfulness of the economic complexity approach.

description: The computational study of chemical reactions in complex, wet environments is critical for applications in many fields. It is often essential to study chemical reactions in the presence of applied electrochemical potentials, taking into account the non-trivial electrostatic screening coming from the solvent and the electrolytes. As a consequence the electrostatic potential has to be found by solving the generalized Poisson and the Poisson-Boltzmann equation for neutral and ionic solutions, respectively. In the present work solvers for both problems have been developed. A preconditioned conjugate gradient method has been implemented to the generalized Poisson equation and the linear regime of the Poisson-Boltzmann, allowing to solve iteratively the minimization problem with some ten iterations of a ordinary Poisson equation solver. In addition, a self-consistent procedure enables us to solve the non-linear Poisson-Boltzmann problem. Both solvers exhibit very high accuracy and parallel efficiency, and allow for the treatment of different boundary conditions, as for example surface systems. The solver has been integrated into the BigDFT and Quantum-ESPRESSO electronic-structure packages and will be released as an independent program, suitable for integration in other codes.

description: Classical wave fields are real-valued, ensuring the wave states at opposite frequencies and momenta to be inherently identical. Such a particle-hole symmetry can open up new possibilities for topological phenomena in classical systems. Here we show that the historically studied two-dimensional (2D) magnetoplasmon, which bears gapped bulk states and gapless one-way edge states near zero frequency, is topologically analogous to the 2D topological $p+\Ii p$ superconductor with chiral Majorana edge states and zero modes. We further predict a new type of one-way edge magnetoplasmon at the interface of opposite magnetic domains, and demonstrate the existence of zero-frequency modes bounded at the peripheries of a hollow disk. These findings can be readily verified in experiment, and can greatly enrich the topological phases in bosonic and classical systems.

description: Purpose: This study evaluated Iraqi medical students’ knowledge of exercise prescription for sedentary, healthy individuals based on the ACSM guidelines after viewing a series of online learning modules. The study also tested the reliability of online learning modules as an instructional tool. Methods: A pilot test was performed on American medical students (n=10) using four online learning modules based on the ACSM guidelines for sedentary, healthy individuals to determine reliability of the pre- and post-test (r ≥ 0.70). All modules were watched in one week to limit outside influences on knowledge acquired. Modules were then provided to Iraqi medical students (n=20) for the experimental component of the study. Identical pre- and post-test were used to determine knowledge acquired. Results: Data for both studies were found to not be normally distributed (p<0.05), therefore a Wilcoxon-signed test was used to test for significance of the data. The differences between pre- and post-test scores for the pilot as well as the experimental studies were found to be statistically significant (p<0.05). A Spearman correlation was calculated for the pre- and post-test scores for both groups (r=0.486 and r=0.504; p<0.05, for the pilot and experimental studies, respectively). Conclusions: Online learning modules significantly increased knowledge in exercise prescription guidelines in both an American and Iraqi medical school population.

description: We have applied the Gamow shell model (GSM) in the coupled-channel representation to study the astrophysical $S$-factor for the proton radiative capture reaction of $^6$Li. Reaction channels are built by coupling the proton wave function expanded in different partial waves with the GSM wave functions of the ground state ($1^+$) and the excited states ($3^+_1$, $0^+_1$ and $2^+_1$) of $^6$Li. All relevant $E1$, $M1$, and $E2$ transitions from the initial continuum states in $^7$Be to the final bound states (${3/2}^-_1$ and ${1/2}^-_1$) states are included. It is found that the calculated total astrophysical $S$ factor for this reaction agrees well with the experimental data.

description: Large magnetic anisotropy energy (MAE) is desirable and critical for nanoscale magnetic devices. Here, using ligand-field level diagrams and density functional calculations, we well explain the very recent discovery [I. G. Rau et al., Science 344, 988 (2014)] that an individual Co adatom on a MgO (001) surface has a large MAE of more than 60 meV. More importantly, we predict that a giant MAE up to 110 meV could be realized for Ru adatoms on MgO (001), and even more for the Os adatoms (208 meV). This is a joint effect of the special ligand field, orbital multiplet, and significant spin-orbit interaction, in the intermediate-spin state of the Ru or Os adatoms on top of the surface oxygens. The giant MAE could provide a route to atomic scale memory.

description: We study the Hamiltonian formulation for a parametrized electromagnetic field with the purpose of clarifying the interplay between parametrization and gauge symmetries. We use a geometric approach which is tailor-made for theories where embeddings are part of the dynamical variables. Our point of view is global and coordinate free. The most important result of the paper is the identification of sectors in the primary constraint submanifold in the phase space of the model where the number of independent components of the Hamiltonian vector fields that define the dynamics changes. This explains the non-trivial behavior of the system and some of its pathologies.

Measuring the psychological drivers of participation in collective action to address violence against women in Mumbai, India

description: A growing number of public health interventions involve community members in activism to prevent violence against women (VAW), but the psychological drivers of participation are poorly understood. In this project, we developed a new scale for measuring three proposed drivers of participation in collective action to address VAW in the context of urban informal settlements in Mumbai, India: perceived legitimacy, perceived efficacy, and collective action norms. Using a household survey of over 2,500 men and women, we examined its item, construct, and criterion validity. A valid scale would provide useful insight into modifiable beliefs and attitudes that community mobilisation interventions can address to inspire activism in low-resource contexts.

description: We consider a certain infinite product of random $2 \times 2$ matrices appearing in the solution of some $1$ and $1+1$ dimensional disordered models in statistical mechanics, which depends on a parameter $\varepsilon>0$ and on a real random variable with distribution $μ$. For a large class of $μ$, we prove the prediction by B. Derrida and H. J. Hilhorst (J. Phys. A 16:2641, 1983) that the Lyapunov exponent behaves like $C \varepsilon^{2 α}$ in the limit $\varepsilon \searrow 0$, where $α\in (0,1)$ and $C>0$ are determined by $μ$. Derrida and Hilhorst performed a two-scale analysis of the integral equation for the invariant distribution of the Markov chain associated to the matrix product and obtained a probability measure that is expected to be close to the invariant one for small $\varepsilon$. We introduce suitable norms and exploit contractivity properties to show that such a probability measure is indeed close to the invariant one in a sense which implies a suitable control of the Lyapunov exponent.
