description: The Gauss-Bonnet gravity is a special case of so-called Quadratic Gravity, which is an extension of Einstein's theory with additional terms in action that are quadratic combinations of the Riemann tensor and its contractions. These corrections are needed, for example, in perturbative quantum gravity. We consider the family of Kundt spacetimes, which is defined in a purely geometrical way by admitting a shear-free, twist-free and expansion-free null geodesic congruence. In particular, we focus on the Kundt solutions without gyratonic terms, and we investigate the constraints imposed by the Einstein-Gauss-Bonnet field equations. The conditions for the metrics to be of various algebraic types are also studied.

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Inspired by the formulation of the Batalin-Vilkovisky method of quantization in terms of ``odd time'', we show that for a class of gauge theories which are first order in the derivatives, the kinetic term is bilinear in the fields, and the interaction part satisfies some properties, it is possible to give the solution of the master equation in a very simple way. To clarify the general procedure we discuss its application to Yang-Mills theory, massive (abelian) theory in the Stueckelberg formalism, relativistic particle and to the self-interacting antisymmetric tensor field.

Some limit laws for quantum walks with applications to a version of the Parrondo paradox

description: A quantum walker moves on the integers with four extra degrees of freedom, performing a coin-shift operation to alter its internal state and position at discrete units of time. The time evolution is described by a unitary process. We focus on finding the limit probability law for the position of the walker and study it by means of Fourier analysis. The quantum walker exhibits both localization and a ballistic behavior. Our two results are given as limit theorems for a 2-period time-dependent walk and they describe the location of the walker after it has repeated the unitary process a large number of times. The theorems give an analytical tool to study some of the Parrondo type behavior in a quantum game which was studied by J. Rajendran and C. Benjamin by means of very nice numerical simulations [1]. With our analytical tools at hand we can easily explore the "phase space" of parameters of one of the games, similar to the winning game in their papers. We include numerical evidence that our two games, similar to theirs, exhibit a Parrondo type paradox.

Bioinspired Algorithms in Bioinformatics

description: In the field of Computer Sciences, Artificial Intelligence can be defined as the ability of reasoning of an artificial agent. In this area, it is used the term of “intelligent machine or intelligent computer”, but instead of “machines”, these are computer algorithms that automatically improve through experience. These are algorithms that “learn” and “adapt” to their environment; this means, a problem to be solved. Thus, we can talk about evolutionary and bio-inspired algorithms, techniques that try to partially replicate behavior of social cooperative and biological systems. Genetic algorithms, genetic programming, particles swarm optimization, ant colony systems, neural networks are classified as bioinspired techniques, among others. In this case, biological and social cooperative concepts are borrowed in order to propose computational algorithms. But, defining these bioinspired algorithms as starting point, these are applied to give solutions of diverse problems in the field of Biology, and now, Bioinformatics emerges as the area of computer sciences algorithms applied to the analysis and processing of biological data. In this talk, some examples will be presented as the sequences alignment (DNA, Proteins and metabolic pathways) problems using genetic algorithms, protein folding using a genetic algorithm, classification of microarrays by means of particle swarm optimization algorithm, and generation of prediction rules by means of genetic programming.

description: In the present work we propose a new initial state model for hydrodynamic simulation of relativistic heavy ion collisions based on Bjorken-like solution applied streak by streak in the transverse plane. Previous fluid dynamical calculations in Cartesian coordinates with an initial state based on a streak by streak Yang-Mills field led for peripheral higher energy collisions to large angular momentum, initial shear flow and significant local vorticity. Recent experiments verified the existence of this vorticity via the resulting polarization of emitted $Λ$ and $\barΛ$ particles. At the same time parton cascade models indicated the existence of more compact initial state configurations, which we are going to simulate in our approach. The proposed model satisfies all the conservation laws including conservation of a strong initial angular momentum which is present in non-central collisions. As a consequence of this large initial angular momentum we observe the rotation of the whole system as well as the fluid shear in the initial state, which leads to large flow vorticity. Another advantage of the proposed model is that the initial state can be given in both [t,x,y,z] and $[τ, x, y, η]$ coordinates, and thus can be tested by all 3+1D hydrodynamical codes which exist in the field.

description:
Background Pay-it-forward is when an individual receives a gift and is offered the opportunity to donate a gift to another person. This prosocial behavior has been used to develop health interventions, including strategies to increase sexually transmitted disease (STD) testing among men who have sex with men (MSM). Although pay-it-forward has improved service uptake across several settings, the underlying mechanism is unclear. This study aims to assess the participant experience to provide a theoretical basis for how pay-it-forward works among MSM in China. Methods MSM participants of a pay-it-forward intervention were recruited from two STD clinics in Guangzhou, China, and underwent semi-structured interviews. Responses were translated verbatim into English. Transcripts were analyzed thematically. Results Twenty-four MSM were interviewed. Despite many men feeling detached from other MSM, pay-it-forward engendered hope and solidarity among many participants. From an emotional perspective, reading handwritten postcards from other MSM induced gratitude, warmth, and support. From the perspective of the collective, receiving a free test and donating to other MSM solidified men's connection with the MSM community, even among men not yet out. Donation gave men an opportunity to pass on their gratitude and provide for MSM in need. Conclusions Our data suggest that upstream reciprocity and warm glow explained pay-it-forward for some men, but this pathway was often complemented by a pathway aligned with principles of mutual aid. Further qualitative and mixed-methods research is needed to understand the basis for MSM decision-making about donating to support others.

description: The repeated agency model has been widely applied to a number of interesting and important problems in economics, though in many instances, the fact that the standard model generates transient dynamics limits the usefulness of the results obtained from the model for the simple reason that purely transient dynamic phenomena are empirically irrelevant since they cannot be systematically observed and studied.

When Good = Better Than Average

subject: FOS: Economics and business

description: People report themselves to be above average on simple tasks and below average on difficult tasks. This paper builds on prior research demonstrating this effect and proposes a simpler explanation for it: that people easily conflate relative with absolute evaluation, especially on ambiguous measures of evaluation. The paper then presents a series of four studies that examine this conflation explanation in successively more stringent tests. These tests distinguish conflation from other explanations, such as regression, differential weighting, and selecting the wrong referent. The effect of absolute performance on ratings of relative performance proves to be remarkably robust, particularly on ambiguous measures, and the results are explained better by conflation than by other theories.

description: A novel design for a vectorial vortex beam launcher in the microwave regime is devised. The beam is formed by launching a single guided transverse electric (TE) mode of a metallic circular waveguide into free-space. Excitation is achieved by the mean of an inserted coaxial loop antenna. Modal expansion coefficients are computed, and the resulting electric and magnetic fields are determined. The effect of the antenna location inside the waveguide on its effective input impedance is modelled using transmission-line relations and location for optimal matching is established. The analytical results are confirmed using multi-level fast multipole method full-wave simulations.

When Advance Purchase need to be Made for Future Consumption – An Empirical Investigation of Consumer Choice under Bucket Pricing

description: Bucket pricing entails a prepaid price and a maximum consumption limit, which requires consumers to make advance purchase decisions before their consumption needs are fully revealed. We propose a dynamic model that involves how consumers form expectations of future consumption needs, learn to reduce uncertainty through experience, and make optimal advance purchase decisions. Applying the model to an online DVD rental history data, we examine how consumption uncertainty may drive advance purchase decisions. Consumers tend to overpurchase to cover the unexpected volatility of future consumption needs, avoid stockouts and switching costs. Over time, consumers learn to reduce uncertainty but only those with lower switching costs adjust their overpurchases to adapt to their reduced uncertainty. Bucket pricing could lead to greater profits if higher-level plans were more attractive, which would induce consumers to overpurchase more. By explicitly modeling advance purchase decision making and empirically investigating consumer decision processes, this article helps managers better understand the effects of price/quota combinations on consumer choice.

description: The International Monetary Fund (IMF) and the World Bank were created in 1944 reflecting the experience of the 1920s and 1930s. The Fund's tasks were to adjust current account imbalances and manage the exchange rate system. The Bank's main tasks were to lend for the reconstruction of Europe and eliminate the alleged bias against lending to developing countries. Whatever may have been true in the 1940s, the international financial system has found other means of solving the problems that the Fund and the Bank were supposed to solve. Changes in exchange rates are now one common means of adjusting current account imbalances. Leading countries including the United States, Japan, Britain and the European Union allow their currencies to float. Within Western Europe there will soon be a common currency with a single central bank in place of fixed but adjustable exchange rates.

description: THE BASIC WORK OF THE COMMISSION ON FINANCIAL STRUCTURE was negotiation. The restrictions on competition in the banking laws and regulations create monopoly positions, two of which turned out to be most important for the members of the commission. Protracted negotiation was required because the commission had to discover the price that commercial bankers were willing to pay to the depository thrift institutions to get them to give up Regulation Q and the 1/2 percent difference in deposit rates maintained by regulation. The price was a share of the commercial banks' monopoly on the demand deposit business and their claim to "one-stop" banking

The compounds with magnetic lanthanide elements show interesting low field magnetism intrigued by possible presence of competing antiferromagnetic and ferromagnetic interactions. The magnetocaloric effect in these compounds is estimated from the field dependent heat capacity data. The magnetic entropy change and the adiabatic temperature change in the vicinity of the magnetic transition are found to be significant.

description: The withdrawal of the United Kingdom (UK) from the European Union (EU), commonly known as Brexit, resulted in the establishment of a new bilateral legal framework for the future development of EU-UK relations. The new framework is based on a Trade and Co-operation Agreement (TCA) in combination with more specific supplementing agreements concerning the exchange of classified information and the peaceful use of nuclear energy. Without entering into a detailed substantive analysis of these agreements, several innovative elements can be highlighted from the perspective of EU external relations law. This includes, in particular, the governance structure of the new legal framework, the use of art. 217 TFEU (on association) as a legal basis, the "EU-only" nature of the TCA and the provisional application without prior involvement of the European Parliament. It is argued that these key features are largely the result of an unprecedented process of negotiations under the time pressure of the expiry date for the transitional application of EU law in the UK.

description: We report on an investigation of the SBS 1520+530 gravitational lens system and its environment using archival HST imaging, Keck spectroscopic data, and Keck adaptive-optics imaging. The AO imaging has allowed us to fix the lens galaxy properties with a high degree of precision when performing the lens modeling, and the data indicate that the lens has an elliptical morphology and perhaps a disk. The new spectroscopic data suggest that previous determinations of the lens redshift may be incorrect, and we report an updated, though inconclusive, value z_lens = 0.761. We have also spectroscopically confirmed the existence of several galaxy groups at approximately the redshift of the lens system. We create new models of the lens system that explicitly account for the environment of the lens, and we also include improved constraints on the lensing galaxy from our adaptive-optics imaging. Lens models created with these new data can be well-fit with a steeper than isothermal mass slope (alpha = 2.29, with the density proportional to r^-alpha) if H_0 is fixed at 72 km/s/Mpc; isothermal models require H_0 ~ 50 km/s/Mpc. The steepened profile may indicate that the lens is in a transient perturbed state caused by interactions with a nearby galaxy.

description: We develop a field theoretical treatment of a model of interacting Brownian particles. We pay particular attention to the requirement of the time reversal invariance and the fluctuation-dissipation relationship (FDR). The method used is a modified version of the auxiliary field method due originally to Andreanov, Biroli and Lefevre [J. Stat. Mech. P07008 (2006)]. We recover the correct diffusion law when the interaction is dropped as well as the standard mode coupling equation in the one-loop order calculation for interacting Brownian particle systems.

Nonsingular Lagrangians for Two Dimensional Black Holes
Creators: name: Banks, T.
name: O'Loughlin, M.
Publisher: name: arXiv
Year: 1992
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We introduce a large class of modifications of the standard lagrangian for two dimensional dilaton gravity, whose general solutions are nonsingular black holes. A subclass of these lagrangians have extremal solutions which are nonsingular analogues of the extremal Reissner-Nordstrom spacetime. It is possible that quantum deformations of these extremal solutions are the endpoint of Hawking evaporation when the models are coupled to matter, and that the resulting evolution may be studied entirely within the framework of the semiclassical approximation. Numerical work to verify this conjecture is in progress. We point out however that the solutions with non-negative mass always contain Cauchy horizons, and may be sensitive to small perturbations.
description: 27 pages, three figures, RU-92-61. (Replaced version contains some corrections to incorrect equations. The zero temperature extremal geometry (the conjectured end-point of the Hawking evaporation) is not as stated in the previous version, but rather is a nonsingular analogue of the zero temperature $M^2 = Q^2$ Reissner-Nordstrom space-time.)
The Environments of SLACS Gravitational Lenses
Creators: name: Auger, M. W.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We report on an investigation of the environments of the SLACS sample of gravitational lenses. The local and global environments of the lenses are characterized using SDSS photometry and, when available, spectroscopy. We find that the lens systems that are best modelled with steeper than isothermal density profiles are more likely to have close companions than lenses with shallower than isothermal profiles. This suggests that the profile steepening may be caused by interactions with a companion galaxy as indicated by N-body simulations of group galaxies. The global environments of the SLACS lenses are typical of non-lensing SDSS galaxies with comparable properties to the lenses, and the richnesses of the lens groups are not as strongly correlated with the lens density profiles as the local environments. Furthermore, we investigate the possibility of line-of-sight contamination affecting the lens models but do not find a significant over-density of sources compared to lines of sight without lenses.

The discursive positioning of the Falkland Islands (las Islas Malvinas): A corpus-based collocational analysis of British and Argentinian websites
Creators: name: Leung, Ray Chung Hang
Publisher: name: Globe: A Journal of Language, Culture and Communication
Year: 2017

description: Considering "discursive positioning" to be a form of "placement," this study examines how the Falkland Islands or las Islas Malvinas, a place which has long been politically controversial, are discursively positioned on British and Argentinian websites. The data came from two reference corpora: namely the Corpus of Global Web-Based English (GloWbE) and the Corpus del Español: Web/Dialects. The 388-million-word British section of the former and the 183-million-word Argentinian section of the latter were selected for analysis. Attention was paid to the 20 most frequent collocates of "Falkland Islands"/"Islas Malvinas." Semantic prosody, collocation networks and word clusters were also investigated. It was found that the Falkland Islands are positioned differently in the two corpora. While the collocates of "Falkland Islands" in the British corpus (e.g., "government" and "population") position the Islands as a territory with "self-determination," the collocates of "Islas Malvinas" in the Argentinian corpus (e.g., "nuestras" [our (feminine plural)], "territorio" [territory] and "recuperación" [recovery], together with the 5-gram "las Islas Malvinas son argentinas" [the Falkland Islands are Argentinian]) subsume the Islands under the ownership of Argentina. Not only are the Falkland Islands "discursively positioned," Britain and Argentina are also subject to positioning. For instance, in the British corpus, Argentina is construed as an invader (as suggested by the collocates "invasion" and "1982") whereas in the Argentinian corpus, Britain is given this demonized role (via the collocates "militar" [military] and "británica" [British (feminine singular)]). Such findings add strength to van Dijk's (2011) discussion of "positive self-presentation and negative other-presentation." As an example of corpus-assisted discourse studies (CADS), the current research also offers solid evidence on the social phenomenon of "classification" proposed by Bourdieu (1990)—i.e., "a vision of the world is a division of the world."

What Should Be Done About Exchange Rates?

Publisher: name: Carnegie Mellon University
Year: 1982
Subjects: subject: 150399 Business and Management not elsewhere classified
subject: FOS: Economics and business

description: One of the pleasures of preparing an essay in Gottfried Haberler's honor comes from rereading some of his past contributions. The two quotations at the start of this essay, although written a generation apart, are as relevant to current discussions of European monetary union and policy coordination as they were to the subjects addressed at the time they were written. The first quotation, criticizing early postwar proponents of a world central bank, reminds us that gains from a common currency—whether for Europe or all the world's open economies—depend on the policy rule adopted by the proposed monetary authority. A policy rule that avoids both inflation and deflation increases welfare; rules, procedures, or discretionary actions that produce price instability do not. This applies equally if the actions are coordinated. Indeed, coordination that produces inflation in all leading countries is clearly worse than uncoordinated policies that leave one or more countries pursuing price stability. The second quotation takes a balanced view of fixed and fluctuating exchange rates. Fixed rates can, in principle, increase welfare. Whether they do so in practice depends on the policies followed by the central banks and governments.
What can Google Trends data tell us about dialect labels: An exploratory study
Creators: name: Jensen, Marie Møller
Publisher: name: Globe: A Journal of Language, Culture and Communication
Year: 2017

description: The aim of this article is twofold: firstly, it sets out to explore the usefulness of Google Trends to the study of language and the perception of variants and, secondly, it investigates the social realities of dialect labels as reflected in searches on the Internet search engine Google. Google Trends is an online tool which is freely available and allows you to map the search volume of search terms across time and space, and also see which other related searches Google users performed within the specified time period or area. In this way, Google Trends can perhaps help us shed light on what it is Google users are curious about or interested in when they search for words such as Geordie, Scouse and Cockney – is it the dialects which the labels denote or is it something else? The study thus takes as its primary interest the application of the Google Trends search tool to the study of folk perceptions of dialect labels and, as a secondary aim, if this can be used to uncover what these dialect labels denote to lay people. With regard to the first aim, the study found that using Google Trends data can be useful in the early stages of perceptual dialectology studies of dialects and dialect labels. With regard to the second aim, the main finding of the study was that there are vast differences between the three dialect labels investigated here, both in terms of sheer search volume over time but also with regard to the collocates with which they are associated. Explanations for some of the patterns of search volume over time and the differences between the three dialect labels are sought by considering the impact of popular culture and TV shows.

description: In this paper we study the mod $2$ cohomology ring of the Grasmannian $\widetilde{G}_{n,3}$ of oriented $3$-planes in $\mathbb{R}^n$. We determine the degrees of the indecomposable elements in the cohomology ring. We also obtain an almost complete description of the cohomology ring. This partial description allows us to provide lower and upper bounds on the cup length of $\widetilde{G}_{n,3}$. As another application, we show that the upper characteristic rank of $\widetilde{G}_{n,3}$ equals the characteristic rank of $\widetildeγ_{n,3}$, the oriented tautological bundle over $\widetilde{G}_{n,3}$.

description: An unusual questionnaire was used to explore what risks concern laypeople. It asked respondents to list, in their own words, as many risks of personal concern as they could. They then selected the five risks of greatest concern and answered a set of specific questions about each. A coding scheme was developed for categorizing these responses and was shown to have good reliability. The questionnaire was administered to a heterogeneous convenience sample of subjects. They reported a very broad range of risks of concern, which differed in plausible ways as a function of their gender and age. Females and student-age subjects were generally more concerned about the environment, whereas males and older subjects were more likely to mention health and safety risks. Both the extent of the risk-reduction actions that they reported and their expressed willingness to pay for future risk reductions were greater for risk that presented a direct personal threat (e.g., health risks) than for risks that posed a diffuse threat to the environment or to people in general (e.g., pollution). Respondents perceived themselves as bearing primary responsibility for managing threats to their own health, but generally saw government as bearing a heavier responsibility for managing environmental risks (especially for pollutants) and war. The questionnaire instrument and coding structure developed for this work are well-suited to a variety of future research applications. They provide a way to identify the risks that concern lay groups, as well as to track the evolution of those concerns over time.

description: We generalize the braid algebra to the case of loops with intersections. We introduce the Reidemeister moves for 4 and 6-valent vertices to have a theory of rigid vertex equivalence. By considering representations of the extended braid algebra, we derive skein relations for link polynomials, which allow us to generalize any link Polynomial to the intersecting case. We perturbatively show that the HOMFLY Polynomials for intersecting links correspond to the vacuum expectation value of the Wilson line operator of the Chern Simon's Theory. We make contact with quantum gravity by showing that these polynomials are simply related with some solutions of the complete set of constraints with cosmological constant
