description: From the seismic data obtained by CoRoT for the star HD 49933 it is possible, as for the Sun, to constrain models of the excitation of acoustic modes by turbulent convection. We compare a stochastic excitation model described in Paper I (arXiv:0910.4027) with the asteroseismology data for HD 49933, a star that is rather metal poor and significantly hotter than the Sun. Using the mode linewidths measured by CoRoT for HD 49933 and the theoretical mode excitation rates computed in Paper I, we derive the expected surface velocity amplitudes of the acoustic modes detected in HD 49933. Using a calibrated quasi-adiabatic approximation relating the mode amplitudes in intensity to those in velocity, we derive the expected values of the mode amplitude in intensity. Our amplitude calculations are within 1-sigma error bars of the mode surface velocity spectrum derived with the HARPS spectrograph. The same is found with the mode amplitudes in intensity derived for HD 49933 from the CoRoT data. On the other hand, at high frequency, our calculations significantly depart from the CoRoT and HARPS measurements. We show that assuming a solar metal abundance rather than the actual metal abundance of the star would result in a larger discrepancy with the seismic data. Furthermore, calculations that assume the ``new'' solar chemical mixture are in better agreement with the seismic data than those that assume the ``old'' solar chemical mixture. These results validate, in the case of a star significantly hotter than the Sun and Alpha Cen A, the main assumptions in the model of stochastic excitation. However, the discrepancies seen at high frequency highlight some deficiencies of the modelling, whose origin remains to be understood.

description: The well-known formula $det(A\cdot B)=\det A \cdot \det B$ can be easily proved for finite dimensional matrices but it may be incorrect for the functional determinants of differential operators, including the ones which are relevant for Quantum Field Theory applications. Considerable work has been done to prove that this equality can be violated, but in all previously known cases the difference could be reduced to renormalization ambiguity. We present the first example, where the difference between the two functional determinants is a nonlocal expression and therefore can not be explained by the renormalization ambiguity. Moreover, through the use of other even dimensions we explain the origin of this difference at qualitative level.

Observational $5-20μ$m Interstellar Extinction Curves Toward Star-Forming Regions Derived from Spitzer IRS Spectra
Creators: name: McClure, M. K.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Using \emph{Spitzer} Infrared Spectrograph observations of G0--M4 III stars behind dark clouds, I construct $5-20μ$m empirical extinction curves for $0.3\leq A_K<7$, which is equivalent to $A_V$ between $\approx$ 3 and 50. For $A_K<1$ the curve appears similar to the \citet{mathis90} diffuse interstellar medium extinction curve, but with a greater degree of extinction. For $A_K>1$, the curve exhibits lower contrast between the silicate and absorption continuum, developes ice absorption, and lies closer to the \citet{wd01} $R_V=5.5$ case B curve, a result which is consistent with that of \citet{flaherty07} and \citet{chiar07}. Recently work using \emph{Spitzer} Infrared Array Camera data by \citet{chapman08} independently reaches a similar conclusion, that the shape of the extinction curve changes as a function of increasing $A_K$. By calculating the optical depths of the $9.7μ$m silicate and 6.0, 6.8, and 15.2 $μ$m ice features, I determine that a process involving ice is responsible for the changing shape of the extinction curve and speculate that this process is coagulation of ice-mantled grains rather than ice-mantled grains alone.

title: Russian-speaking LGBTQ communities in the West
Creators: name: Novitskaya, Alexandra
Publisher: name: Taylor & Francis
Year: 2021

description: This chapter reviews the scholarship on Russian-speaking LGBTQ communities in the three largest post-Soviet diasporas:�the USA, Israel, and Germany. Although there have been important analyses of how the post-Soviet opening of borders led to increases in labor and marriage migration, there has been relatively little work on new possibilities for LGBTQ migrants. LGBTQ migrants have tried a variety of tactics to negotiate their sexuality and post-Soviet cultural heritage, with those in the 1990s USA unable to come out as queer in the diaspora and those in Israel distancing themselves from the Russian identity. Based on more recent studies conducted in Berlin and New�York City, LGBTQ status has become a factor driving migration. Those in Berlin immigrated to escape heteronormativity in post-Soviet societies, and those in New�York City become politicized as their asylum status depends on their lived experience as LGBTQ. In the latter case, the phenomenon is gendered:�lesbian and bisexual women are under-represented, perhaps because, as women, they have fewer resources for immigration and are more socialized to stay connected to their families. Moreover, since asylum adjudicators tend to privilege visible homophobic violence, more often experienced by gay men in post-Soviet societies, women seem less likely to obtain asylum.

description: We use the self-consistent stellar populations in the Binary Population A Spectral Synthesis (BPASS) models to assess whether NGC1850-BH1 is a black hole. Using search criteria based on reported physical properties in the literature we purposefully search for suitable systems with a black hole (or compact object) companion: we do not find any. Good matches to the observations are found in models where the bright component is a stripped star and the companion is natively (meaning we did not impose this in our search) 1 to 2.3 magnitudes fainter than the primary in the optical bands. This alone can explain the lack of detection of the companion in the MUSE spectra without the need to invoke rapid rotation, although the conservative mass transfer exhibited by these particular models is likely to lead to rapidly rotating companions which could further smear their spectroscopic signatures. We advise that future claims of unseen black holes in binary systems would benefit from exploring detailed binary evolution models of stellar populations as a sanity check

Subjects: subject: Cryptography and Security (cs.CR)

description: The wireless medium contains domain-specific information that can be used to complement and enhance traditional security mechanisms. In this paper we propose ways to exploit the spatial variability of the radio channel response in a rich scattering environment, as is typical of indoor environments. Specifically, we describe a physical-layer authentication algorithm that utilizes channel probing and hypothesis testing to determine whether current and prior communication attempts are made by the same transmit terminal. In this way, legitimate users can be reliably authenticated and false users can be reliably detected. We analyze the ability of a receiver to discriminate between transmitters (users) according to their channel frequency responses. This work is based on a generalized channel response with both spatial and temporal variability, and considers correlations among the time, frequency and spatial domains. Simulation results, using the ray-tracing tool WiSE to generate the time-averaged response, verify the efficacy of the approach under realistic channel conditions, as well as its capability to work under unknown channel variations.

description: From the point of view of the fictionalisation of Science in Literature and the contribution of women to the development of Science, the article discusses how the practice of palaeontology and geological studies is represented in British historical fiction of our own times, through two female characters, who were contemporaries of Jane Austen. After a few considerations of a general nature regarding the construction of the contemporary historical novel and some observations concerning the true state of paleontological and geological studies in the first decades of the nineteenth century the article will move on to deal with the way the choice of these two areas of Earth Science fulfilled the author’s objectives.

description: Recent BICEP/Keck data on the cosmic microwave background, in combination with previous WMAP and Planck data, impose strong new constraints on the tilt in the scalar perturbation spectrum, $n_s$, as well as the tensor-to-scalar ratio, $r$. These constrain the number of e-folds of inflation, $N_*$, the magnitude of the inflaton coupling to matter, $y$, and the reheating temperature, $T_{\rm reh}$, which we evaluate in attractor models of inflation as formulated in no-scale supergravity. The 68% C.L. region of $(n_s, r)$ favours large values of $N_*, y$ and $T_{\rm reh}$ that are constrained by the production of gravitinos and supersymmetric dark matter.

description: Our objective was to design a quantum repeater capable of achieving one million entangled pairs per second over a distance of 1000km. We failed, but not by much. In this letter we will describe the series of developments that permitted us to approach our goal. We will describe a mechanism that permits the creation of entanglement between two qubits, connected by fibre, with probability arbitrarily close to one and in constant time. This mechanism may be extended to ensure that the entanglement has high fidelity without compromising these properties. Finally, we describe how this may be used to construct a quantum repeater that is capable of creating a linear quantum network connecting two distant qubits with high fidelity. The creation rate is shown to be a function of the maximum distance between two adjacent quantum repeaters.

Notas sobre a gravação técnica do som

description: O registo sonoro, nomeadamente música e voz, iniciou-se no final do século XIX. Primeiro, foram registos puramente mecânicos (há registos mecânicos mais antigos, como em brinquedos, mas sem capacidade de gravar sons da natureza, da voz humana e da música em concerto). A eletrificação das máquinas de gravação simplificou o registo sonoro. Uma florescente indústria discográfica alargou-se a todo o mundo, após o seu arranque nos Estados Unidos. De acordo com o gosto musical da época, os primeiros discos contemplavam a música clássica, mas, já na década de 1930, surgiam discos de música ligeira. A rádio, com emissoras potentes em todos os continentes, além da informação, tinha a programação baseada na música, estimulando a indústria fonográfica e impondo gostos musicais. Em meados da década de 1940, apareceu o magnetofone, um gravador de fita magnética, de origem alemã, mais fiável que o gravador de fita de aço americano. Após a II Guerra Mundial, a rádio e os gira-discos tornaram os lares burgueses em verdadeiras pistas de dança, com músicas alegres. As tecnologias de registo sonoro evoluíram tanto que se adicionaram pistas de gravação e se manipularam sons que os registos iniciais não comportavam. Seriam os casos dos discos Pet Sounds, dos Beach Boys (1966), com a música Good Vibrations, e Sgt Pepper’s Lonely Hearts Band, dos Beatles (1966-1967), cuja reprodução num concerto ao vivo se tornou impossível. A indústria fonográfica ganhava à rádio, até aí a grande produtora dos gostos estéticos.

description: In this paper we present the evolution of a low mass model (initial mass M=1.5 Msun) with a very low metal content (Z=5x10^{-5}, equivalent to [Fe/H]=-2.44). We find that, at the beginning of the AGB phase, protons are ingested from the envelope in the underlying convective shell generated by the first fully developed thermal pulse. This peculiar phase is followed by a deep third dredge up episode, which carries to the surface the freshly synthesized 13C, 14N and 7Li. A standard TP-AGB evolution, then, follows. During the proton ingestion phase, a very high neutron density is attained and the s-process is efficiently activated. We therefore adopt a nuclear network of about 700 isotopes, linked by more than 1200 reactions, and we couple it with the physical evolution of the model. We discuss in detail the evolution of the surface chemical composition, starting from the proton ingestion up to the end of the TP-AGB phase.

description: Central to active learning (AL) is what data should be selected for annotation. Existing works attempt to select highly uncertain or informative data for annotation. Nevertheless, it remains unclear how selected data impacts the test performance of the task model used in AL. In this work, we explore such an impact by theoretically proving that selecting unlabeled data of higher gradient norm leads to a lower upper-bound of test loss, resulting in better test performance. However, due to the lack of label information, directly computing gradient norm for unlabeled data is infeasible. To address this challenge, we propose two schemes, namely expected-gradnorm and entropy-gradnorm. The former computes the gradient norm by constructing an expected empirical loss while the latter constructs an unsupervised loss with entropy. Furthermore, we integrate the two schemes in a universal AL framework. We evaluate our method on classical image classification and semantic segmentation tasks. To demonstrate its competency in domain applications and its robustness to noise, we also validate our method on a cellular imaging analysis task, namely cryo-Electron Tomography subtomogram classification. Results demonstrate that our method achieves superior performance against the state of the art.

Para uma museologia da religião análise da carta-circular “a função pastoral dos museus eclesiásticos” vinte anos depois
Creators: name: Roque, Maria Isabel
Publisher: name: Gaudium Sciendi
Year: 2022

description: A Igreja Católica assume uma longa tradição na salvaguarda do seu património cultural, histórico e artístico. Os tesouros eclesiásticos medievais, cumprindo as funções de depósito, inventariação, conservação e exposição, são os antecedentes históricos dos museus eclesiásticos e constituem uma referência obrigatória na proto-história da museologia. No entanto, apenas em finais do século XVIII, com a instituição dos museus e a conexa incorporação de bens eclesiásticos, se assinala a conversão do objeto sagrado ou religioso em objeto museológico. Desde então e, em particular, após o Concílio Vaticano II, a Igreja tem demonstrado uma crescente preocupação em garantir, aos objetos retirados do culto, um destino digno de sua condição litúrgica original. Nesse sentido, a Carta-Circular Função pastoral dos museus eclesiásticos, publicada em 2001, determinava que o museu eclesiástico fosse considerado como um recurso válido e adequado à preservação desses objetos, mantendo-os na proximidade do grupo cultural de origem e dando continuidade à sua função catequética original. Assim, o museu eclesiástico diferencia-se dos restantes por ser confessional, vinculando uma perspetiva espiritual e pastoral à função cultural dos museus, o que, garantindo o rigor da informação, se torna um fator positivo na recontextualização e inteligibilidade do objeto religioso. Além disso, ao referir a interação entre o museu eclesiástico e o território, no quadro referencial dos conceitos de museu integrado e difuso, a Carta propunha uma via de atuação que coincide com o desenvolvimento da museologia atual centrada no público e na experiência do visitante. Passadas duas décadas sobre a sua publicação, propõe-se uma análise crítica da Carta no quadro teórico dos estudos museológicos, a fim de confirmar o seu caráter atualizado, se não pioneiro, no que respeita à recuperação da função e do sentido original do objeto no discurso museológico, à ligação ao território e à cultura do lugar numa perspetiva global e diacrónica, e à interação com o público plural e heterogéneo.

The governance of three, post-secondary, two-year colleges in British Columbia, Canada
Creators: name: Gray, Robert William
Publisher: name: University of British Columbia
Year: 2010

description: This study describes, and analyses the activities of the lay governing boards of three, recently established, two-year, post-secondary colleges in British Columbia, Canada. Such descriptions and analyses will prove useful to persons interested in the continuing development of two-year colleges in the Province, and may also serve to throw some additional light on the activities of, and problems faced by, lay governing boards In a wide range of organization types. The descriptions of governing board activities were guided by the work of Strauss et al. (1963) in which he suggested that an organization, at a given point in time, be viewed as a combination of a formal order and negotiated order or working arrangements. Defined in terms of written rules and/or legislation, the formal order of the three boards was determined by inspection of relevant legislation and regulations. Working arrangements were defined in terms of a decision making process (after Rubenstein and Haberstroh, 1966), having as its content certain organization problems. The nature of these problems was suggested by the work of Talcott Parsons (1960,1963,1968,1969), and R.J.Hills (1972). The working arrangements of the three boards were determined through interviews with persons closely associated with the boards. It was found that the majority of governing board decisions had to do with the procurement of resources for, and in the determination, of the kinds of services to be offered by, the college. While final approval for decisions in a number of substantive areas was found to be the responsibility of a Government Department, the decision making activities of the boards usually consisted of the consideration, and approval of recommendations brought to-the boards by the administrations of the colleges. A number of possible areas of change in the activities of the governing boards were identified, along with a number of problems. It appeared that most, of the problems had arisen as a result of the newness of the governing boards and as a result of some confusion over their role in the two-year colleges. The study concludes with a number of recommendations for change.

description: The polarization dependence of the near edge x-ray absorption spectroscopy (XANES) is an element specific probe to the real-space distribution of the density of unoccupied states in solid-state materials. In this paper, we present Fe and As $K$-edge experiments of Ba(Fe$_{1-x}$$M_{x}$)$_{2}$As$_{2}$ ($M=$ Mn, Co and $x=0.0$ and $0.08$). The experiments reveal a strong polarization dependence of the probed XANES spectra, which concerns mainly an increase of the intensity of electronic transitions when the beam polarization is set out of the sample's $ab$ crystallographic plane. The results show that states with $p_{z}$-orbital character dominate the density of unoccupied states close to the Fermi level. Partial substitution of Fe by Co is shown to decrease the intensity anisotropy, suggesting that Co promotes electronic transfer preferentially to states with $p_{z}$-orbital character. On the other hand, Mn substitution causes the increase of the spectra $p_{z}$-orbital anisotropy, which is proposed to take place by means of an enhanced local Fe $3d4p$ mixing, unveiling the role of Fe $4p$ states in the localization of the Fe $3d$ orbitals. Moreover, by comparing our results to previous experiments, we identify the relative mixing between Fe and the pnictide $4p_{x,y,z}$ orbitals as a clear divide between the electronic properties of iron arsenides and selenides. Our conclusions are supported by multiple-scattering theory calculations of the XANES spectra and by quantum chemistry calculations of Fe coordination electronic structure.

description: This paper is a contribution to the theoretical foundations of strategies. We first present a general definition of abstract strategies which is extensional in the sense that a strategy is defined explicitly as a set of derivations of an abstract reduction system. We then move to a more intensional definition supporting the abstract view but more operational in the sense that it describes a means for determining such a set. We characterize the class of extensional strategies that can be defined intensionally. We also give some hints towards a logical characterization of intensional strategies and propose a few challenging perspectives.
title: Relationality as Resistance: Dismantling Colonialism and Racial Capitalism
Creators: name: Gonzalez Mendoza, Yolanda
Publisher: name: University of Georgia Press
Year: 2023

description: Abolishing Poverty argues for a project of relationality that refuses the whiteness of liberal poverty studies and instead centers critiques of the poverty relation and political futures disavowed under liberal governance. In disrupting poverty thinking, the author collective opens space for diverse frameworks for understanding impoverishment and articulating antiracist knowledges and political visions. The book explores new infrastructures of possibilities and political solidarities rooted in accountable relations to each other and from flights to the future that animate diverse communities.This book is boundary and genre crossing, with broad appeal to scholars of such disciplines as human geography, ethnic studies, decolonial theory, and feminist studies. As a volume, the work is unique in its primary field of human geography in the form of its making, its collective authorship, and its investigation of politics that abolish poverty thinking and engage in activism against the poverty relation produced through settler colonialism, heteropatriarchy, white supremacy, and capitalist exploitation.
Balloons over the volcano: ecocriticism, vengeful nature and apocalyptic anxieties
Creators: name: Ramos, Iolanda Freitas
Publisher: name: Gaudium Sciendi
Year: 2022

description: The 1883 eruption of Krakatoa was a major natural disaster that had a profound impact on the global climate for at least five years. Drawing on the consequences of the volcanic eruption, this essay begins by approaching how the geographic effects and the optical phenomena inspired the arts, as far as sketches and paintings of a darkened sky and beautiful sunsets were concerned. It then looks at how the implicit meaning of apocalyptic weather as nature’s response to man’s abuse was discussed in Ruskin’s The Storm-Cloud of the Nineteenth Century (1884), a text that not only embodied civilisational anxieties but foresaw ecocritical discourses. The essay proceeds to briefly address natural disasters as leitmotifs of the literary and filmic imagination used in the science-fiction genre for the purpose of setting up a dystopian situation. Finally, it focuses on William Pène du Bois’s The Twenty-One Balloons (1947) in order to examine how the novel recreates the Krakatoa catastrophe as a background to what can be regarded as a utopian story for children and to illustrate how a fictional representation distorts a non-fictional cataclysm.

description: One kind of particularly interesting pseudoscalar particles, called axion-like particles (ALPs), have rich physical phenomenology at high- and low-energy collider experiments. After discussing most of single production channels of ALP at electron-positron colliders, we investigate the possibility of detecting this kind of new particles through the W$^{+}$W$^{-}$ fusion process e$^{+}$e$^{-}$ $\rightarrow$ $\overlineν_{e}$$ν_{e}a$ $(\rightarrow γγ)$ at the CLIC. The 3$σ$ and 5$σ$ bounds on the ALP parameter space at the three energy stages of the CLIC are obtained. We find that the bounds given by the CLIC are complementary to the existing experiments exclusion regions.

“Encerrar” e “desencerrar” ou a arte da capeia em “uma corrida de toiros no sabugal”, de Abel Botelho (1854-1917)
Creators: name: Pina, Margarida Esperança
Publisher: name: Gaudium Sciendi
Year: 2022

description: São muitos os testemunhos (de tradição oral, entre outros) que procuram dizer a cultura arraiana. Mas o que se pretende é tentar avaliar o património cultural em torno da capeia arraiana, a partir do conto “Uma corrida de toiros no Sabugal”, publicado por Abel Botelho em Mulheres da Beira (1898). A capeia arraiana é uma corrida de touros típica das terras de Riba Côa, nas aldeias da raia e pensa-se que tenha tido origem num acordo entre os ganadeiros da província espanhola de Salamanca e as aldeias portuguesas. Uma vez por ano, cediam algumas vacas bravas para, de alguma forma, compensar os estragos causados pelo gado espanhol que atravessava a raia para pastar nas hortas e lameiros portugueses. Pretendemos, deste modo, revisitar o primeiro conto que se assume como verdadeiro testemunho semântico e poético desse acervo arraiano. E, sob este olhar, acreditamos que a partir de um código literário, a linguagem dos toiros se transforma num diálogo vivo entre a simbólica e o imaginário do património cultural imaterial dos povos da raia.

description: Through this research I have tried to demonstrate how the evolution of the newest marketing strategies - that work towards engaging relationships with consumers, thus building an emotional connection between the brand and the user- can be considered as a response to the evolution of young audiences and consumers.
More specifically, I have analized product placement as a cultural and social phenomena above all, and not only as an economical one, thus demonstrating all the social and cultural practices that this tool implies.
The approach I have chosen to do so, is historical-analytical, particularly focusing on the evolution of the society and of the consumer, especially for what teenagers (both as audiences and as consumers) are concerned.

description: The notion of nonpositive curvature in Alexandrov's sense is extended to include p-uniformly convex Banach spaces. Infinite dimensional manifolds of semi-negative curvature with a p-uniformly convex tangent norm fall in this class on nonpositively curved spaces, and several well-known results, such as existence and uniqueness of best approximations from convex closed sets, or the Bruhat-Tits fixed point theorem, are shown to hold in this setting, without dimension restrictions. Homogeneous spaces G/K of Banach-Lie groups of semi-negative curvature are also studied, explicit estimates on the geodesic distance and sectional curvature are obtained. A characterization of convex homogeneous submanifolds is given in terms of the Banach-Lie algebras. A splitting theorem via convex expansive submanifolds is proven, inducing the corresponding splitting of the Banach-Lie group G. Finally, these notions are used to study the structure of the classical Banach-Lie groups of bounded linear operators acting on a Hilbert space, and the splittings induced by conditional expectations in such setting.

description: We study oscillation death (OD) in a well-known coupled-oscillator system that has been used to model cardiovascular phenomena. We derive exact analytic conditions that allow the prediction of OD through the two known bifurcation routes, in the same model, and for different numbers of coupled oscillators. Our exact analytic results enable us to generalize OD as a multiparameter-sensitive phenomenon. It can be induced, not only by changes in couplings, but also by changes in the oscillator frequencies or amplitudes. We observe synchronization transitions as a function of coupling and confirm the robustness of the phenomena in the presence of noise. Numerical and analogue simulations are in good agreement with the theory.

A importância do estudo da literatura para a infância na academia: um contributo central e cordial de Maria Laura Bettencourt Pires
Creators: name: Pereira, Cláudia Sousa
Publisher: name: Gaudium Sciendi
Year: 2022

description: O presente texto é uma revisitação da importante obra da Professora Maria Laura Bettencourt Pires, incontornável para quem se dedica ao estudo consistente e persistente do subsistema da literatura e cultura infantojuvenil em Portugal. Trata-se da História da Literatura Infantil em Portugal, publicada na editora Vega em 1983 (ou 1982, já que as várias referências que encontrámos não concordam na data e a ausência desta na única edição não nos permitiu desambiguar a questão, pelo que optámos por 1983), e é a primeira sistematização, no panorama académico e editorial, etapa inaugural que se reclama quando se constitui um campo de estudos - a sua história – para prosseguir na teorização e aplicação nas abordagens mais consistentes de obras, autores e contextos. A obra é prefaciada por um dos vultos mais importantes do século XX no que respeita à divulgação de obras e figuras históricas, Adolfo Simões Müller, jornalista e autor que adaptou, em versões de leitura facilitada, obras clássicas e nos deixou relatos das vidas de grandes figuras universais, numa preocupação em disseminar, por um maior número possível de leitores, cultura no sentido de erudição por conhecimento de factos. O nosso texto tem em particular conta esse prefácio, ao mesmo tempo provocador e crítico de uma certa situação que vigorava à data da publicação da História, mas também a Nota Final da autora. A opção pela incidência do nosso foco nestes dois textos, prende-se com a relevância do pioneirismo do trabalho da professora Maria Laura Bettencourt Pires e com a sua elevada consciência da importância de se trabalhar uma literatura que, tendo em conta, no momento da sua criação, as competências limitadas dos leitores mais jovens, não cede um milímetro na qualidade literária. Mesmo quando, aos olhos de hoje, essa qualidade não se desliga de certos preconceitos e de práticas e formas de pensar anacrónicas, sobretudo quando comparamos os livros publicados para crianças então, com os que são publicados nos dias de hoje. A esta qualidade da obra, a Professora e Investigadora acrescenta uma perspetiva que tem em conta fenómenos internacionais que conferem ao panorama português quer uma especificidade, quer uma integração que continuam a contribuir para a relevância do estudo da literatura e cultura para a infância e a juventude na academia e, acrescentamos, para além da preocupação coma formação de profissionais do ensino básico e secundário.

description: We propose a surface plasmon-polariton based nano-rod array lens structure that incorporates two additional lateral input channels, with the ability to control the focal length and the deflection of the transmitted beam through the lens actively by the intensity of the channel sources. We demonstrate by numerical simulations that, applying the sources with the same intensity can change the focal point and the beam waist, whereas unequal intensities generate an asymmetric field profile in the nano-rod array inducing an off-axis beam deflection.

description: This work is dedicated to the study of damaging phenomena involving reinforced concrete structures and masonry buildings  and the consequences in terms of structural performances decay. 
In the Italian context there are many examples of structures  that have already exceeded their service life, considering not only the ancient buildings but also infrastructures and R/C buildings that today are operating from more than 50th years. Climate change which is subject to the entire planet, with changing in seasonal weather and  increasing in environmental pollution, is not excluded could have a harmful influence on the rate of building materials decay previously deemed as durables. If the aggressive input changes very fast, for example in a few decades, then it can also change the response of a construction material considered so far durable; in this way the knowledge about the art of good build, consolidated  over the centuries, is thwarted. Hence this study is focused on the possibility to define the residual capacity for vertical or seismic loads for structures that are already at the limit of their service life, or for which is impossible to define a service life. The problem in an analysis of this kind, and that is what makes this research different from the main studies avaibles in the literature, is to keep in correlation – in a not so expensive computationally way – issues such as: 
- dangerous environmental inputs adequately simulated; 
- environmental conditions favorable to the spread of pollutants and development of the degradation reactions (decay’s speed); 
- link between environmental degradation and residual bearing capacity 
A more realistic assessment of materials residual performances that constitute the structure  allows to leave the actual system for the residual load-bearing capacity estimation in  which all factors are simply considered through the use of a safety factor on the materials properties.
