description: We report high spatial resolution 11.2 and 18.1 micron imaging of the eruptive variable V838 Monocerotis, obtained with Gemini Observatory's Michelle in 2007 March. The 2007 flux density of the unresolved stellar core is roughly 2 times brighter than that observed in 2004. We interpret these data as evidence that V838 Mon has experienced a new circumstellar dust creation event. We also report a gap of spatially extended thermal emission over radial distances of 1860-93000 AU from the central source, which suggests that no prior significant circumstellar dust production events have occurred within the past 900-1500 years.

Energy and system dependence of high-$p_T$ triggered two-particle near-side correlations

description: Previous studies have indicated that the near-side peak of high-$p_T$ triggered correlations can be decomposed into two parts, the \textit{Jet} and the \textit{Ridge}. We present data on the yield per trigger of the \textit{Jet} and the \textit{Ridge} from $d+Au$, $Cu+Cu$ and $Au+Au$ collisions at $\sqrt{s_{NN}}$ = 62.4 GeV and 200 GeV and compare data on the \textit{Jet} to PYTHIA 8.1 simulations for $p+p$. PYTHIA describes the \textit{Jet} component up to a scaling factor, meaning that PYTHIA can provide a better understanding of the \textit{Ridge} by giving insight into the effects of the kinematic cuts. We present collision energy and system dependence of the \textit{Ridge} yield, which should help distinguish models for the production mechanism of the \textit{Ridge}.

A Rigorous Derivation of Gravitational Self-force

description: There is general agreement that the MiSaTaQuWa equations should describe the motion of a "small body" in general relativity, taking into account the leading order self-force effects. However, previous derivations of these equations have made a number of ad hoc assumptions and/or contain a number of unsatisfactory features. For example, all previous derivations have invoked, without proper justification, the step of "Lorenz gauge relaxation", wherein the linearized Einstein equation is written down in the form appropriate to the Lorenz gauge, but the Lorenz gauge condition is then not imposed--thereby making the resulting equations for the metric perturbation inequivalent to the linearized Einstein equations. In this paper, we analyze the issue of "particle motion" in general relativity in a systematic and rigorous way by considering a one-parameter family of metrics, $g_{ab} (λ)$, corresponding to having a body (or black hole) that is "scaled down" to zero size and mass in an appropriate manner. We prove that the limiting worldline of such a one-parameter family must be a geodesic of the background metric, $g_{ab} (λ=0)$. Gravitational self-force--as well as the force due to coupling of the spin of the body to curvature--then arises as a first-order perturbative correction in $λ$ to this worldline. No assumptions are made in our analysis apart from the smoothness and limit properties of the one-parameter family of metrics. Our approach should provide a framework for systematically calculating higher order corrections to gravitational self-force, including higher multipole effects, although we do not attempt to go beyond first order calculations here. The status of the MiSaTaQuWa equations is explained.

Direct Mediation, Duality and Unification

description: It is well-known that in scenarios with direct gauge mediation of supersymmetry breaking the messenger fields significantly affect the running of Standard Model couplings and introduce Landau poles which are difficult to avoid. This appears to remove any possibility of a meaningful unification prediction and is often viewed as a strong argument against direct mediation. We propose two ways that Seiberg duality can circumvent this problem. In the first, which we call "deflected-unification", the SUSY-breaking hidden sector is a magnetic theory which undergoes a duality to an electric phase, with fewer elementary degrees of freedom coupled to the MSSM. This changes the beta-functions of the MSSM gauge couplings so as to push their Landau poles above the unification scale. We show that this scenario is realised for recently suggested models of gauge mediation based on a metastable SCQD-type hidden sector directly coupled to MSSM. The second possibility, which we call "dual-unification", begins with the observation that, if the mediating fields fall into complete SU(5) multiplets, then the MSSM+messengers exhibits a fake unification at unphysical values of the gauge couplings. We show that, in known examples of electric/magnetic duals, such a fake unification in the magnetic theory reflects a real unification in the electric theory. We therefore propose that the Standard Model could itself be a magnetic dual of some unknown electric theory in which the true unification takes place. This scenario maintains the unification prediction (and unification scale) even in the presence of Landau poles in the magnetic theory below the GUT scale. We further note that this dual realization of grand unification can explain why Nature appears to unify, but the proton does not decay.

description: Agenda 2063 is an ambitious fifty (50) year plan detailing the aspirations and goals of the African continent for the future. Building on the strengths and weaknesses of previous plans as introduced by the OAU which later transformed to the AU, Agenda 2063 is built on seven (7) key aspirations, each with its own set goals that reflects the vision for a united and prosperous Africa. The study adopted a theoretical review by using literatures in line with the topic under consideration for careful analysis. It was found out that despite huge prospects for development in Africa using this agenda, some challenges which include the unavailability or lack of adequate investment in the human, natural, and financial capacity needed to achieve these future projections hamper the goals of Agenda 2063. To avoid these challenges that plagued previous plans for Africa, this study makes a case for the full integration of STEM education in the African education system especially in this era driven by technological innovations. This paper recommends an overhaul of the African education curriculum before this integration, so that African students can design solutions for real-life African problems.

description: A characterisation of scintillating fibres with silicon photomultiplier read-out was performed in view of their possible application in fibre tracking detector systems. Such a concept is being considered for the Kaos spectrometer at the Mainz Microtron MAMI and as a time-of-flight start detector for the hypernuclear physics programme at the PANDA experiment of the FAIR project. Results on particle detection effciency and time resolution are discussed. In summary, the silicon devices are very suitable for the detection of the low light yield from scintillating fibres insofar a trigger scheme is found to cope with the noise rate characteristics.

description: Tracking locations is practical and speditive with smartphones, as they are omnipresent devices, relatively cheap, and have the necessary sensors for positioning and networking integrated in the same box. Nowadays recent models have GNSS antennas capable of receiving multiple constellations. In the proposed work we test the hypothesis that GNSS positions directly recorded by smartphones can be a valid solution for spatial analysis of people's behaviour in an urban garden. Particular behaviours can be linked to therapeutic spots that promote health and well-being of visitors. Three parts are reported: (i) assessment of the accuracy of the positions relative to a reference track, (ii) implementation of a framework for automating transmission and processing of the location information, (iii) analysis of preferred spots via spatial analytics. Different devices were used to survey at different times and with different methods, i.e. in the pocket of the owner or on a rigid frame. Accuracy was estimated using distance of each located point to the reference track, and precision was estimated with static multiple measures. A chat-bot through the Telegram application was implemented to allow users to send their data to a centralized computing environment thus automating the spatial analysis. Results report a horizontal accuracy below ~2.3 m at 95% confidence level, without significant difference between surveys, and very little differences between devices. GNSS-only and assisted navigation with telephone cells also did not show significant difference. Autocorrelation of the residuals over time and space showed strong consistency of the residuals, thus proving a valid solution for spatial analysis of walking behaviour.
Hydrodynamical Velocity Fields in Planetary Nebulae

description: Based on axi-symmetric hydrodynamical simulations and 3D reconstructions with Shape, we investigate the kinematic signatures of deviations from homologous ("Hubble-type") outflows in some typical shapes of planetary nebulae. We find that, in most situations considered in our simulations, the deviations from a Hubble-type flow are significant and observable. The deviations are systematic and a simple parameterization of them considerably improves morpho-kinematical models of the simulations. We describe such extensions to a homologous expansion law that capture the global velocity structure of hydrodynamical axi-symmetric nebulae during their wind-blown phase. It is the size of the poloidal velocity component that strongly influences the shape of the position velocity diagrams that are obtained, not so much the variation of the radial component. The deviations increase with the degree of collimation of the nebula and they are stronger at intermediate latitudes. We describe potential deformations which these deviations might produce in 3D reconstructions that assume "Hubble-type" outflows. The general conclusion is that detailed morpho-kinematic observations and modeling of planetary nebulae can reveal whether a nebula is still in a hydrodynamically active stage (windy phase) or whether it has reached ballistic expansion.

Some issues in the planning and implementation of a holistic health care model for a primary health care setting in the United States
Creators: name: Smith, Rodney E. (Rodney Edward)
Publisher: name: University of British Columbia
Year: 2010

description: It is argued that the holistic health care movement in the United States has emerged as a response to dissatisfactions with the existing health care delivery system—a system which has become too concerned with technological solutions and insufficiently concerned with social and psychosocial issues. The holistic health care movement is defined. The movement's emphasis on prevention through the use of teamwork and its concern with whole patient care is explained. Next consideration is given to the present process of planning, financing and delivering health services in the United States; and the other models which have been developed to try to take account of prevention, social and psychosocial issues are described and criticized. The way in which holistic health care needs to be organized is described—the need for involvement of allied health professionals such as nutritionists and psychologists is discussed and better record keeping is examined. The need to be open to new techniques such as acupuncture and other marginal activities is argued. The difficulties in financing are discussed. However, discussion of a model health center presently operating in Illinois gives hope that demonstrations may convince Americans that it is a service worth paying for. The method of introducing new models of health service delivery into the United States is examined. They are generally accepted by the upper-middle class and then work down through the system. It is argued that the model (holistic health care) is quite likely to become more widely accepted because it appeals to the American individualistic, selfhelp ideology. Whilst it may work itself down the class structure it is not likely to solve social problems because the orientation is psychosocial and individualistic.
Circuits of Mobile Workers in the 19th-Century Central Balkans

description: This article compares the geographic and social mobility of two “lesser known” groups of workers: merchants’ assistants and maidservants. By combining labor mobility, class, and gender as categories of analysis, it suggests that such examples of temporary and return migration opened up new economic possibilities while at the same time reinforcing patriarchal order and increasing social inequality. Such transformative social practice is placed within the broader socio-economic and political fabric of the late Ottoman and post-Ottoman Balkans during the “long 19th century.”

description: We report the first real world implementation of a Quantum Key Distribution (QKD) system over a 43dB-loss transmission line in the Swisscom fibre optic network. The QKD system is capable of continuous and autonomous operation and uses the coherent one-way (COW) protocol. This system brings together three key concepts for future QKD systems: a simple high-speed protocol; high performance detection; and integration, both at the component level as well for connectivity with standard fibre networks. Here, we show laboratory and field trial results for this system. The full prototype version uses InGaAs/InP avalanche photodiodes (APDs) and was laboratory tested up to 150km, with a 10-hour exchange averaging around 2kbps of real-time distilled secret bits over 100km. In the field trials, we obtained average distribution rates, during 3 hours, of 2.5bps over a 43dB-loss line of 150km, when using superconducting single photon detectors (SSPDs).

description: 12. Acrolophidae – tube moths Small to medium-sized (15–35 mm wingspan) drab tan and brown mottled moths with rounded wings and stout bodies. Larvae construct long silken tubes in soil or litter. Most species feed on detritus or plant debris, but some feed on living plants, dung, or fungi. Acrolophids are restricted to the New World, and their diversity is highest in the neotropics. Approximately 270 species are known worldwide, and 64 species are known from North America, mostly from the Southwest. One species is known from AB. Two genera of acrolophids occur in North America; Acrolophus was revised by Hasbrouck (1964), and Amydria was treated by Dietz (1905) as part of the subfamily Amydriinae in the Tineidae. In many older works, this family was placed within the Tineidae. 54 * R Amydria effrentella Clemens, 1859 Jun m – G T: Dietz (1905) L: Bowman (1951) C: CNC, NFRC

Mobile Intellectuals as Agents of Nationalism in the 19th-Century Balkans

Publisher: name: Austrian Journal of Historical Studies
Year: 2020

description: Within the context of migration studies, this article examines a specific category of modern migration in Europe, that of the revolutionary-intellectual, focusing on the 19th-century Balkans and the Bulgarian paradigm. It employs the biographical method in studying the careers of two distinguished protagonists of the Revival, Georgi Rakovski and Liuben Karavelov, placing emphasis on the interrelationship between mobility and ideological orientations. It is in this light that their life courses, itineraries, social back- grounds and ideological profiles are examined. Their middle-class origins and education steered them away from their native villages in their quest to have careers as teachers, newspaper editors, writers etc. Being continuously on the move, they adopted and propagated through their writings modern ideologies, namely liberalism and federalism interrelated with nationalism, and organised armed uprisings against Ottoman rule.

description: A magnetohydrodynamic (MHD) shock front can be unstable to the corrugation instability, which causes a perturbed shock front to become increasingly corrugated with time. An ideal MHD parallel shock (where the velocity and magnetic fields are aligned) is unconditionally unstable to the corrugation instability, whereas the ideal hydrodynamic (HD) counterpart is unconditionally stable. For a partially ionised medium (for example the solar chromosphere), both hydrodynamic and magnetohydrodynamic species coexist and the stability of the system has not been studied. In this paper, we perform numerical simulations of the corrugation instability in two-fluid partially-ionised shock fronts to investigate the stability conditions, and compare the results to HD and MHD simulations. Our simulations consist of an initially steady 2D parallel shock encountering a localised upstream density perturbation. In MHD, this perturbation results in an unstable shock front and the corrugation grows with time. We find that for the two-fluid simulation, the neutral species can act to stabilise the shock front. A parameter study is performed to analyse the conditions under which the shock front is stable and unstable. We find that for very weakly coupled or very strongly coupled partially-ionised system the shock front is unstable, as the system tends towards MHD. However, for a finite coupling, we find that the neutrals can stabilise the shock front, and produce new features including shock channels in the neutral species. We derive an equation that relates the stable wavelength range to the ion-neutral and neutral-ion coupling frequencies and the Mach number. Applying this relation to umbral flashes give an estimated range of stable wavelengths between 0.6 and 56 km.

We show that WIMPless dark matter with mass around 2-10 GeV can explain the annual modulation observed by the DAMA experiment without violating the constraints of other dark matter searches. This explanation implies distinctive and promising signals for other direct detection experiments, GLAST, and the LHC.

description: In this paper, an algebraic theory for local rings of finite embedding dimension is developed. Several extensions of (Krull) dimension are proposed, which are then used to generalize singularity notions from commutative algebra. Finally, variants of the homological theorems are shown to hold in equal characteristic. This theory is then applied to Noetherian local rings in order to get: (i) over a Cohen-Macaulay local ring, uniform bounds on the Betti numbers of a Cohen-Macaulay module in terms of dimension and multiplicity, and similar bounds for the Bass numbers of a finitely generated module; (ii) a characterization for being respectively analytically unramified, analytically irreducible, unmixed, quasi-unmixed, normal, Cohen-Macaulay, pseudo-rational, or weakly F-regular in terms of certain uniform arithmetic behavior; (iii) in mixed characteristic, the Improved New Intersection Theorem when the residual characteristic or ramification index is large with respect to dimension (and some other numerical invariants).

Nevertheless it has proven to be an attractive target for machine learning research because of the potential for even modest levels of prediction accuracy to deliver significant benefits. In this paper, we describe a case-based reasoning approach to predicting stock market returns using only historical pricing data. We argue that one of the impediments for case-based stock prediction has been the lack of a suitable similarity metric when it comes to identifying similar pricing histories as the basis for a future prediction -- traditional Euclidean and correlation based approaches are not effective for a variety of reasons -- and in this regard, a key contribution of this work is the development of a novel similarity metric for comparing historical pricing data. We demonstrate the benefits of this metric and the case-based approach in a real-world application in comparison to a variety of conventional benchmarks.

description: We describe spherically symmetric steady-state accretion of perfect fluid in the Reissner-Nordstrom metric. We present analytic solutions for accretion of a fluid with the linear equations of state and of the Chaplygin gas. It is also shown that, under reasonable physical conditions, there is no steady-state accretion of a perfect fluid onto a Reissner-Nordstrom naked singularity. Instead, a static atmosphere of fluid is formed. We discuss a possibility of violation of the third law of black hole thermodynamics for a phantom fluid accretion.

The Fashion of Politics. Argentina from the 1940s to the 2000s
Creators: name: Castagnola, Gustavo
Publisher: name: Austrian Journal of Historical Studies

description: Deeply marked by Peronism’s emergence, all along the second half of the twentieth century, in Argentina external appearance functioned not merely as a powerful symbol of politics but also and, particularly, as the precise way in which politics and society related to each other. Since the descamisados (shirtless: name that desig- nated General Perón’s supporters) and Eva Perón’s clothing in the 1940’s until the mini-skirts and beards in the 1970’s (which were used as clues by the last Argentine military dictatorship to identify political adversaries), ways of dressing up expressed the very character of Argentine politics and the nature of the relationship between political and social issues in this country. The purpose of this article is, on the one hand, to revisit Argentine history during the second half of the twentieth century by examining the main images that politics conferred to and received from society; and, on the other, to employ the conclusions that can be drawn from this revision to analyse Argentine present crisis in historical perspective.

Objects, Speed, and the Film within the Film: Vachel Lindsay and Classical Cinema as an Alternative Public Sphere
Creators: name: Suárez, Juan A.
Publisher: name: Austrian Journal of Historical Studies
Year: 2004

description: This essay reads Vachel Lindsay’s film theory as symptomatic of an oscillation, still present in the period of early classical cinema, between the ordering effect of the classical codes and the centrifugal potential of the film image. Lindsay located this potential in the dispersive effect of filmed objects and spaces. According to Lindsay, these could derail the unity of the narrative and might be actualized by audiences as alternative public spheres, that is, as sites for the articulation of dissident fantasies and desires. Hence, even though Lindsay was primarily invested in disciplining the film text and its viewers, and enlisting the cinema for the promotion of national and cultural unity, he lucidly outlined the structure of a dissident form of spectatorship that has recurred in both experimental cinema and subcultural forms of textual practice.

Aesthetic Judgment and the Public Sphere in the Thought of Hannah Arendt
Creators: name: Zerilli, Linda M.G.
Publisher: name: Austrian Journal of Historical Studies
Year: 2004

description: This essay is on the conception of political space as a space of singular events, rhetorical speech and plurality. It shows that Arendt’s deep suspicion of a cognitively-based practice of political judgment is not based on a naïve concept of logical reasoning. Her point is not to exclude so-called rational discourse or knowledge claims from the practice of aesthetic or political judgment – as if something or someone could stop us from making arguments in public contexts – but to press us to think about what we are doing when we reduce the practice of politics or judgment to the contest of better arguments. She disputes not the idea of argument as such but rather the assumption (central to Habermas’ discourse ethics) that agreement in procedures for making arguments ought to produce agreement in conclusions, hence agreement in the political realm can be reached in the manner of giving proofs.

description: Secondary positrons are produced by spallation of cosmic rays within the interstellar gas. Measurements have been typically expressed in terms of the positron fraction, which exhibits an increase above 10 GeV. Many scenarios have been proposed to explain this feature, among them some additional primary positrons originating from dark matter annihilation in the Galaxy. The PAMELA satellite has provided high quality data that has enabled high accuracy statistical analyses to be made, showing that the increase in the positron fraction extends up to about 100 GeV. It is therefore of paramount importance to constrain theoretically the expected secondary positron flux to interpret the observations in an accurate way. We find the secondary positron flux to be reproduced well by the available observations, and to have theoretical uncertainties that we quantify to be as large as about one order of magnitude. We also discuss the positron fraction issue and find that our predictions may be consistent with the data taken before PAMELA. For PAMELA data, we find that an excess is probably present after considering uncertainties in the positron flux, although its amplitude depends strongly on the assumptions made in relation to the electron flux. By fitting the current electron data, we show that when considering a soft electron spectrum, the amplitude of the excess might be far lower than usually claimed. We provide fresh insights that may help to explain the positron data with or without new physical model ingredients. PAMELA observations and the forthcoming AMS-02 mission will allow stronger constraints to be aplaced on the cosmic--ray transport parameters, and are likely to reduce drastically the theoretical uncertainties.

Parliamentarism: A Politics of Temporal and Rhetorical Distances
Creators: name: Palonen, Kari
Publisher: name: Austrian Journal of Historical Studies
Year: 2004

description: Frank Ankersmit has revised our understanding of political representation in terms of an aesthetic distance between the represented and representatives. The advantage of the parliamentary politics lies also in a rhetorical and temporal distance between the practices of MPs and those of the citizen-voters. The parliamentary democracy is constituted temporally through its procedures and practices. The parliamentary time is rhetorical, based on speaking for and against, in utramque partem, and the parliamentary procedure consists of temporal units aiming at guaranteeing that opposed points of view can be heard. To speak in the presence of the adversaries in the parliament alludes to the omnipresence of alternatives in parliamentary politics. The citizens, occasional politicians (Weber), can liberate themselves in the ballot box from their everyday ›being‹ and vote as if they were MPs. So we could give a rhetorical redesciption to Rousseau’s dictum that Englishmen are free only on the election day.

Computational methods for Markov decision problems

Publisher: name: University of British Columbia
Year: 2010

description: In this thesis we study computational methods for finite discounted Markov decision problems and finite discounted parametric Markov decision problems over an infinite horizon. For the former problem our emphasis is on finding methods to significantly reduce the effort required to determine an optimal policy. We discuss the implementation of Porteus' scalar extrapolation methods in the modified policy iteration algorithm and show that the results using only a final scalar extrapolation will be the same as those obtained by applying scalar extrapolation at each iteration and then using a final scalar extrapolation. Action elimination procedures for policy iteration and modified policy iteration algorithms are presented. The purpose of these techniques is to reduce the size of the action space to be searched in the improvement phase of the algorithm. A method for eliminating non-optimal actions for all subsequent iterations using upper and lower bounds on the optimal expected total discounted return is presented along with procedures for eliminating actions that cannot be part of the policy chosen in the improvement phase of the next iteration. A numerical comparison of these procedures on Howard's automobile replacement problem and on a large randomly generated problem suggests that using modified policy iteration together with one of the single iteration elimination procedures will lead to large savings in the computational time for problems with large state spaces. Modifications of the algorithm to reduce storage space are also discussed. For the finite discounted Markov decision problems in which the reward vector is parameterized by a scalar we present an algorithm to determine the optimal policy for each value of the parameter within an interval. The algorithm is based on using approximations of values to resolve difficulties caused by roundoff error. Also, several action elimination procedures are presented for this problem. Bi-criterion Markov decision problems and Markov decision problems with a single constraint are formulated as parametric Markov decision problems. A numerical comparison of algorithms with and without action elimination procedures is carried out on a two criterion version of Howard's automobile replacement problem. The results suggest that the algorithm with one of the action elimination procedures will lead to efficient solution of this problem.
Improving SUSY Spectrum Determinations at the LHC with Wedgebox Technique

description: The LHC has the potential not only to discover supersymmetry (SUSY), but also to permit fairly precise measurements of at least a portion of the sparticle spectrum. Proposed mass reconstruction methods rely upon either inverting invariant mass endpoint expressions or upon solving systems of mass-shell equations. These methodologies suffer from the weakness that one certain specific sparticle decay chain is assumed to account for all the events in the sample. Taking two examples of techniques utilizing mass-shell equations, it is found that also applying the wedgebox technique allows for the isolation of a purer event sample, thus avoiding errors, possibly catastrophic, due to mistaken assumptions about the decay chains involved and simultaneously improving accuracy. What is innovative is using endpoint measurements (via the wedgebox technique) to obtain a more homogeneous, well-understood sample set rather than just using said endpoints to constrain the values of the masses (here found by the mass-shell technique). The fusion of different established techniques in this manner represents a highly profitable option for LHC experimentalists who will soon have data to analyze.
