description: Clusters of galaxies are believed to be capable to accelerate protons at accretion shocks to energies exceeding 10^18 eV. At these energies, the losses caused by interactions of cosmic rays with photons of the Cosmic Microwave Background Radiation (CMBR) become effective and determine the maximum energy of protons and the shape of the energy spectrum in the cutoff region. The aim of this work is the study of the formation of the energy spectrum of accelerated protons at accretion shocks of galaxy clusters and of the characteristics of their broad band emission. The proton energy distribution is calculated self-consistently via a time-dependent numerical treatment of the shock acceleration process which takes into account the proton energy losses due to interactions with the CMBR. We calculate the energy distribution of accelerated protons, as well as the flux of broad-band emission produced by secondary electrons and positrons via synchrotron and inverse Compton scattering processes. We find that the downstream and upstream regions contribute almost at the same level to the emission. For the typical parameters characterising galaxy clusters, the synchrotron and IC peaks in the spectral energy distributions appear at comparable flux levels. For an efficient acceleration, the expected emission components in the X-ray and gamma-ray band are close to the detection threshold of current generation instruments, and will be possibly detected with the future generation of detectors.

description: O presente artigo visa discutir as temáticas do património cultural e do turismo, concretamente, refletir sobre a forma como o turismo oferece o património cultural. Considerando o caso específico do conjunto arquitetónico dos Clérigos, ambiciona-se problematizar a questão da oferta do património cultural em Portugal. De forma a concretizar os objetivos propostos, analisa-se um conjunto de guias de informação turística para perceber como ‘olham’ e ‘oferecem’ o património cultural em questão. O trabalho divide-se em dois momentos: no primeiro identificam-se os aspetos relativos ao conjunto arquitetónico dos Clérigos presentes nos guias de informação turística analisados e no segundo procede-se a um conjunto de reflexões relativas ao conteúdo dos guias e à questão da oferta do património cultural pelo turismo.

Competing interactions and symmetry breaking in the Hubbard-Holstein model

Publisher: name: arXiv
Year: 2009
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Competing interactions are often responsible for intriguing phase diagrams in correlated electron systems. Here we analyze the competition of instantaneous short range Coulomb interaction $U$ with the retarded electron-electron interaction induced by an electron-phonon coupling $g$ as described by the Hubbard-Holstein model. The ground state phase diagram of this model in the limit of large dimensions at half filling is established. The study is based on dynamical mean field theory combined with the numerical renormalization group. Depending on $U$, $g$, and the phonon frequency $ω_0$, the ground state is antiferromagnetically (AFM) or charge ordered (CO). We find quantum phase transitions from the AFM to CO state to occur when $U-λ\simeq 0$, where $λ$ characterizes the phonon induced effective attraction. The transition is continuous for small couplings and large phonon frequencies $ω_0$ and becomes discontinuous for large couplings and small values of $ω_0$. We comment on the possible relevance of this work for Ba${}_{1-x}$K${}_x$BiO${}_3$.

description: No Brasil, a gastronomia tem sido cada vez mais valorizada pelos visitantes como um forte atrativo turístico. Os últimos estudos realizados pelo Ministério do Turismo (2011, 2012) revelam que, durante a viagem, os turistas que visitaram o país vivenciaram experiências muito positivas com a gastronomia brasileira. Esta investigação apresenta o potencial da gastronomia como produto turístico de Fortaleza, um dos principais destinos turísticos do país. A cidade possui um leque variado de pratos típicos, no qual se destaca um em especial: a tapioca. Esta iguaria está fortemente presente no quotidiano da população local, fato que contribuiu para que a tapioca passasse a ser confecionada nos locais de grande consumo turístico. A análise do potencial da tapioca como produto turístico de Fortaleza destaca inicialmente a relevância histórico-cultural deste produto. Com base nas avaliações feitas por turistas nacionais e estrangeiros no Tripadvisor, pode-se ainda perceber como este prato é valorizado no âmbito da procura turística. Foram analisados também conteúdos online acerca da tapioca, promovidos pelos órgãos oficiais do turismo do destino. Conclui-se neste estudo que a tapioca é um produto com grande potencial histórico-cultural e económico, que pode vir a ser uma marca forte do destino Fortaleza. Contudo há uma grande necessidade de governança na comercialização deste produto, principalmente no que se refere à interação entre produtores e agentes ligados ao turismo.

Social criticism in the English novel : Dickens to Lawrence
Creators: name: Lendvoy, Leonard Roy
Publisher: name: University of British Columbia
Year: 2010

description: The thesis studies the social criticism in five English novels written between 1850 and 1913. All the novels can be located in the central tradition of realistic English fiction. The thesis focuses on the thematic similarities of three Victorian novels: Great Expectations, Hard Times, and Middlemarch, and two early modern novels: Jude the Obscure and Sons and Lovers. The novels voice the authors' criticisms of social, and more specifically family, conditioning. The novelists portray the arbitrary ethical norms that define and regulate behavior within specific social environments. Each novel describes the individual's aspirations which are ultimately frustrated by external forces. Although more than half a century separates the publications of Hard Times and Sons and Lovers the critical perspectives of the novelists are essentially the same. The thesis isolates aspects of the novels which realistically portray the attitudes and values of mid and late Victorian society. One avenue of investigation discusses those institutions which enforce the prevailing social doctrine. The dramatic conflict analyzed in this thesis is often between the adolescent and characters, usually older, who personify the repressive doctrine. Much of the anxiety experienced by the protagonists is a result of the confrontation of individual desire and internalized social norms. In Great Expectations and Hard Times Dickens portrays the childhood and adolescent consciousness as it emerge's within a given moral climate. The thesis analyzes how Dickens isolates and criticizes those aspects of Gradgrindery which are dehumanizing and soul-destroying. The first chapter also compares the experiences of the protagonists in Middlemarch to those of Great Expectations and Hard Times. George Eliot heightens the psychological realism by detailing the subjective conflicts within characters. The second chapter describes how Jude the Obscure and Sons and Lovers maintain the focus on the external manipulation of individual desire. The thesis compares how Hardy and Lawrence chronicle the crucial childhood and adolescent experiences of Jude Fawley and Paul Morel respectively. The second chapter analyzes those relationships and conflicts of the major and minor characters which amplify the theme of social repression. The final chapter of the thesis discusses another manifestation of social repression in Jude the Obscure and Sons and Lovers. In these novels this theme is expressed, for the first time in English fiction, in explicit sexual terms. The thesis isolates those external influences, both social and domestic, which inhibit the psycho-sexual development of Jude Fawley and Paul Morel. The family, largely maternal, conditioning of Sue Bridehead and Miriam Leivers is also analyzed as another amplification of the central thematic focus on social conditioning.

description: Neste artigo pretende-se comparar a leitura do patrimônio histórico edificado de São Luís do Maranhão promovido pelo trade turístico através dos materiais de divulgação impressos e a leitura do mesmo patrimônio pelos ludovicenses (gentílico de São Luís), visando dar suporte à melhor promoção do destino São Luís do Maranhão, a partir das questões: (i) quais são os patrimônios históricos edificados divulgados pelo trade turístico de São Luís; e (ii) qual a leitura dos ludovicenses do seu centro histórico tombado pela Organização das Nações Unidas para a Educação, a Ciência e a Cultura (UNESCO). A teoria de Vicente Del Rio (1991) constitui o principal suporte teórico-metodológico. Com abordagem qualitativa, descritiva e exploratória foram estudados os materiais de divulgação impressos do destino durante as comemorações dos quatrocentos anos de fundação francesa (2010 a 2012) e os dados primários, coletados por meio de questionários semiestruturados com moradores de São Luís que usam com frequência o centro histórico e estão envolvidos na atividade turística. A pesquisa se desenvolveu entre os meses de dezembro de 2013 e janeiro de 2014. Verificou-se que as paisagens eleitas pelos moradores de São Luís nem sempre coincidem com aquelas eleitas pelo trade para a promoção do destino.

description: O reconhecimento crescente da necessidade de diversificar a oferta turística de regiões costeiras associadas ao produto sol e mar, a par da ascensão do turismo cultural e do segmento do turismo literário, conduz à consideração da valorização de recursos culturais regionais. Este artigo circunscreve-se à região do Algarve (Portugal) e pretende, através da interligação entre recursos de património literário e arquitetónico/iconológico associados à casa algarvia, apresentar possibilidades de reforço identitário potenciadoras de valorização da experiência turística. Assim, a partir da análise do conteúdo de textos de Raul Brandão, Emiliano da Costa, António Ramos Rosa, Teresa Rita Lopes, Miguel Torga e Yvette K. Centeno, nos quais o Algarve é o pano de fundo, foram analisadas representações literárias da casa vernacular algarvia identificando-se as características e as funções dos elementos arquitetónicos que a constituem. A análise possibilitou evidenciar a existência de narrativas interpretativas que reforçam o genius loci ou espírito do lugar, pondo em destaque a associação simbiótica entre património tangível e intangível.

Dark Matter Freeze-In with a Heavy Mediator: Beyond the EFT Approach

description: We study dark matter freeze-in scenarios where the mediator particle that couples dark matter to Standard Model fermions is heavier than the reheat temperature TRH in the early Universe. In such setups, the standard approach is to work with an effective field theory (EFT) where the mediator is integrated out. We examine the validity of this approach in various generic s- and t-channel mediator frameworks, and the regime and manner of its breakdown. We find that the EFT approach breaks down when the mediator is between one to two orders of magnitude above TRH, as various factors not considered in the EFT, such as s-channel resonance, a small, thermally suppressed abundance of the mediator, or decays of Standard Model particles through loops induced by the mediator, become the dominant source of dark matter production. This highlights the necessity of including these contributions in such dark matter freeze in studies. We also discuss the collider phenomenology of the heavy mediators, which is qualitatively different from standard freeze-in scenarios.
How intangible heritage should contribute to sustainable development of rural tourism: a case study in the province of Cordoba, Andalusia (Spain)

description: The evolution of tourism from a standard model to segmented, flexible and tailor-made forms has resulted in a growing interest in the rural environment and what it can contribute to a return to genuine ways of life. The Spanish region of Andalusia has a highly recognized potential in rural tourism as it preserves a rich natural and cultural heritage closely linked to local communities, mainly in the broader rural context. The purpose of this paper is to show how intangible heritage could contribute as an effective and strategic tool for the promoting of the economic, social and environmental development of rural tourism in the province of Cordoba. This descriptive work has been completed using qualitative methodology that includes ethnographic observations and interviews, together with local newspapers and a review of municipal archives. The detailed study, focusing on the province of Cordoba, shows how expressions of intangible heritage, herein also referred to as festive rituals or fiestas, are closely linked to seasonal patterns and nature through the surrounding landscape of every town and village; furthermore it preserves both the identity of the local community and the collective memory, at the same time reducing the risk of acculturation. The conclusions aim to provide a benchmark for decision making in the promotion of sustainable development for rural tourism in Cordoba based on expressions of intangible heritage.

The kinematics and chemical stratification of the Type Ia supernova remnant 0519-69.0

description: We present an analysis of the XMM-Newton and Chandra X-ray data of the young Type Ia supernova remnant 0519-69.0 in the Large Magellanic Cloud. We used data from both the Chandra ACIS and XMM-Newton EPIC-MOS instruments, and high resolution X-ray spectra obtained with the XMM-Newton Reflection Grating Spectrometer. The Chandra data show that there is a radial stratification of oxygen, intermediate mass elements and iron, with the emission from more massive elements more toward the center. Using a deprojection technique we measure a forward shock radius of 4.0(3) pc and a reverse shock radius of 2.7(4) pc. We took the observed stratification of the shocked ejecta into account in the modeling of the X-ray spectra with multi-component NEI models, with the components corresponding to layers dominated by one or two elements. An additional component was added in order to represent the ISM, which mostly contributed to the continuum emission. This model fits the data well, and was also employed to characterize the spectra of distinct regions extracted from the Chandra data. From our spectral analysis we find that the fractional masses of shocked ejecta for the most abundant elements are: M(O)=32%, M(Si/S)=7%/5%, M(Ar+Ca)=1%, and M(Fe) = 55%. From the continuum component we derive a circumstellar density of nH= 2.4(2)/cm^3. This density, together with the measurements of the forward and reverse shock radii suggest an age of 450+/-200 yr,somewhat lower than, but consistent with the estimate based on the optical light echo (600+/-200 yr). From the RGS spectra we measured a Doppler broadening of sigma=1873+/-50 km/s, from implying a forward shock velocity of vS = 2770+/-500 km/s. We discuss the results in the context of single degenerate explosion models, using semi-analytical and numerical modeling, and compare the characteristics of 0519-69.0 with those of other Type Ia supernova remnants.

description: We continue the study of heterotic non-Abelian BPS-saturated flux tubes (strings). Previously, such solutions were obtained [1] in a particular U(2) gauge theory: N=2 supersymmetric QCD deformed by superpotential terms of a special type breaking N=2 supersymmetry down to N=1. Here we generalize the previous results to U(N) gauge theories. As was suggested by Edalati and Tong [2], the string world sheet theory is a heterotic N=(0,2) sigma model, with the CP(N-1) target space for bosonic fields and an extra right-handed fermion which couples to the fermion fields of the N=(2,2) CP(N-1) model. We derive the heterotic N=(0,2) world sheet model directly from the U(N) bulk theory. Parameters of the bulk theory are related to those of the world sheet theory. Qualitatively this relation turns out to be the same as in the U(2) case.

description: HDAC6 has emerged as a molecular target to treat neurodegenerative disorders, due to its participation in protein aggregate degradation, oxidative stress process, mitochondrial transport, and axonal transport. Thus, in this work we have designed a set of 485 compounds with hydroxamic and bulky-hydrophobic moieties that may function as HDAC6 inhibitors with a neuroprotective effect. These compounds were filtered by their predicted ADMET properties and their affinity to HDAC6 demonstrated by molecular docking and molecular dynamics simulations. The combination of in silico with in vitro neuroprotective results allowed the identification of a lead compound (FH-27) which shows neuroprotective effect that could be due to HDAC6 inhibition. Further, FH-27 chemical moiety was used to design a second series of compounds improving the neuroprotective effect from 2- to 10-fold higher (YSL-99, YSL-109, YSL-112, YSL-116 and YSL-121; 1.25 ± 0.67, 1.82 ± 1.06, 7.52 ± 1.78, 5.59 and 5.62 ± 0.31 µM, respectively). In addition, the R enantiomer of FH-27 (YSL-106) was synthesized, showing a better neuroprotective effect (1.27 ± 0.60 µM). In conclusion, we accomplish the in silico design, synthesis, and biological evaluation of hydroxamic acid derivatives with neuroprotective effect as suggested by an in vitro model.

description: We construct new families of non-supersymmetric sourceless type IIA AdS4 vacua on those coset manifolds that also admit supersymmetric solutions. We investigate the spectrum of left-invariant modes and find that most, but not all, of the vacua are stable under these fluctuations. Generically, there are also no massless moduli.

description: We consider quivers/skew-symmetric matrices under the action of mutation (in the cluster algebra sense). We classify those which are isomorphic to their own mutation via a cycle permuting all the vertices, and give families of quivers which have higher periodicity. The periodicity means that sequences given by recurrence relations arise in a natural way from the associated cluster algebras. We present a number of interesting new families of non-linear recurrences, necessarily with the Laurent property, of both the real line and the plane, containing integrable maps as special cases. In particular, we show that some of these recurrences can be linearised and, with certain initial conditions, give integer sequences which contain all solutions of some particular Pell equations. We extend our construction to include recurrences with parameters, giving an explanation of some observations made by Gale. Finally, we point out a connection between quivers which arise in our classification and those arising in the context of quiver gauge theories.

The spectral shift function for compactly supported perturbations of Schrödinger operators on large bounded domains

description: We study the asymptotic behavior as L \to \infty of the finite-volume spectral shift function for a positive, compactly-supported perturbation of a Schrödinger operator in d-dimensional Euclidean space, restricted to a cube of side length L with Dirichlet boundary conditions. The size of the support of the perturbation is fixed and independent of L. We prove that the Cesàro mean of finite-volume spectral shift functions remains pointwise bounded along certain sequences L_n \to \infty for Lebesgue-almost every energy. In deriving this result, we give a short proof of the vague convergence of the finite-volume spectral shift functions to the infinite-volume spectral shift function as L \to\infty . Our findings complement earlier results of W. Kirsch [Proc. Amer. Math. Soc. 101, 509 - 512 (1987), Int. Eqns. Op. Th. 12, 383 - 391 (1989)] who gave examples of positive, compactly-supported perturbations of finite-volume Dirichlet Laplacians for which the pointwise limit of the spectral shift function does not exist for any given positive energy. Our methods also provide a new proof of the Birman--Solomyak formula for the spectral shift function that may be used to express the measure given by the infinite-volume spectral shift function directly in terms of the potential.

Entropy and set cardinality inequalities for partition-determined functions

description: A new notion of partition-determined functions is introduced, and several basic inequalities are developed for the entropy of such functions of independent random variables, as well as for cardinalities of compound sets obtained using these functions. Here a compound set means a set obtained by varying each argument of a function of several variables over a set associated with that argument, where all the sets are subsets of an appropriate algebraic structure so that the function is well defined. On the one hand, the entropy inequalities developed for partition-determined functions imply entropic analogues of general inequalities of Plünnecke-Ruzsa type. On the other hand, the cardinality inequalities developed for compound sets imply several inequalities for sumsets, including for instance a generalization of inequalities proved by Gyarmati, Matolcsi and Ruzsa (2010). We also provide partial progress towards a conjecture of Ruzsa (2007) for sumsets in nonabelian groups. All proofs are elementary and rely on properly developing certain information-theoretic inequalities.

The Nature of the Atmosphere of the Transiting Super-Earth GJ 1214b

Year: 2010
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: The newly discovered planet GJ 1214b is the first known transiting super-Earth requiring a significant atmosphere to explain its observed mass and radius. Models for the structure of this planet predict that it likely possesses a H-He envelope of at least 0.05% of the total mass of the planet. However, models without a significant H-He atmosphere are not entirely ruled out by the available data. Here we explore a range of possible atmospheres for the planet, ranging from solar composition gas, to pure CO_2 or water (steam). We present transmission and emission spectra for each of these cases. We find that, if GJ 1214b possesses a hydrogen-rich atmosphere as expected, then the primary transit depth for such an atmosphere would vary at a level of up to 0.3% as a function of wavelength, relative to the background light of its M-dwarf host star. Observations at this level of precision are potentially obtainable with current space-based instrumentation. Successful detection of the transmission signature of this planet at the ~0.1% level would therefore provide confirmation of the hydrogen-rich nature of the planetary atmosphere. It follows that transmission spectroscopy at this level of precision could provide a first glimpse into answering the question of whether planets in the super-Earth mass regime (1 - 10 M_Earth) more closely resemble large terrestrial planets or small gas giant planets.

description: This study investigates defections from the Al-Shabaab insurgency in Somalia. Thirty-two disengaged Al-Shabaab combatants were interviewed about their motivations, grievances, needs, and challenges in relation to the recruitment, defection, and post-defection phases. This paper focuses on post-defection challenges, where we found the primary concern to be lack of personal security. Without adequate security, disengaged combatants are vulnerable to being hunted and killed by Al-Shabaab. This significant threat discourages further mass and individual defections. We also found that disengaged combatants joined and defected out of religious zeal, to fight for what they believed to be a holy Islamic cause. This same zeal led them to defect, as they came to believe Al-Shabaab was not obeying the true Islamic faith. Indiscriminate killing by Al-Shabaab disenchants its religiously pious members, creating an opportunity to encourage mass and individual defections. However, if disengaged combatants are not protected from retribution, defection will lose its appeal.

Energy spectra and fluxes for Rayleigh-Benard convection

description: We compute the spectra and fluxes of the velocity and temperature fields in Rayleigh-Bénard convection in turbulent regime for a wide range of Prandtl numbers using pseudo-spectral simulations on $512^3$ grids. Our spectral and flux results support the Kolmogorov-Obukhov (KO) scaling for zero Prandtl number and low Prandtl number ($P=0.02$) convection. The KO scaling for the velocity field in zero-Prandtl number and low-Prandtl number convection is because of the weak buoyancy in the inertial range (buoyancy is active only at the very low wavenumbers). We also observe that for intermediate Prandtl numbers ($P=0.2$) the KO scaling fits better with the numerical results than the Bolgiano-Obukhov (BO) scaling. For large Prandtl number ($P=6.8$), the spectra and flux results are somewhat inconclusive on the validity of the KO or BO scaling, yet the BO scaling is preferred over the KO scaling for these cases. The numerical results for P=1 is rather inconclusive.
