description: Starting from the anthropological perspective presented by Hans Belting and related to the medium-image-body triad, this article offers a recontextualization of the current condition of images. According to Marie-José Mondza, this is a ‘radical’ issue which is particularly relevant to the context of political and mass media communication. The complexity of creating and enjoying images is due to the nature of ‘the visible’. Therefore, asking what images are is actually a multifaceted question concerning their meaning, their distribution, and their transformation. Thrown into a condition of technological reproducibility and subordinated to the interests of a ‘spectacle’ society, the images of the 21st century need to be constantly interpreted following their movement and transformations. This paper focuses on the living nature of images and proposes a re-appropriation of words and images which have been subject to political and business interests. This paper proposes an alternative model that reflects the historical-anthropological and political need of a rebirth of images in order to grasp their potential as forms of life. Il presente articolo, partendo dalla prospettiva antropologica presentata da Hans Belting nei termini della triade mezzo-immagine-corpo, procede verso una ricontestualizzazione delle condizioni delle immagini del nostro tempo. La questione è presentata come “radicale” da Marie-José Mondzain e assume una particolare rilevanza per la comunicazione politica e massmediatica. La complessità del fare e fruire immagini si ricollega alla natura del visibile. Pertanto, chiedersi cosa siano le immagini è in realtà una domanda sfaccettata che riguarda il loro significato, la loro diffusione e la loro trasformazione. Gettate in una condizione di riproducibilità tecnica e per lo più assoggettate ai fini di una “società dello spettacolo”, le immagini del XXI secolo richiedono di essere costantemente interpretate seguendo il movimento e le trasformazioni che vivono. Il saggio propone un riconoscimento della natura vivente dell'immagine e un invito alla riappropriazione di parole e immagini "sequestrate" dagli interessi politici e dalle leggi del mercato. Esso descrive un modello alternativo che coincide con la manifestazione della necessità storico-antropologica, oltre che politica, di una rinascita delle immagini per cogliere le potenzialità intrinseche in simili forme di vita.

description: In recent years, the stars of the Of?p category have revealed a wealth of peculiar phenomena: varying line profiles, photometric changes, and X-ray overluminosity are only a few of their characteristics. Here we review their physical properties, to facilitate comparisons among the Galactic members of this class. As one of them has been proposed to resemble the magnetic oblique rotator Theta Ori C, though with a longer period, this latter object is also included in our study to illuminate its similarities and differences with the Of?p category.

description: Stationarity of the constituents of the body and of its functionalities is a basic requirement for life, being equivalent to survival in first place. Assuming that the resting state activity of the brain serves essential functionalities, stationarity entails that the dynamics of the brain needs to be regulated on a time-averaged basis. The combination of recurrent and driving external inputs must therefore lead to a non-trivial stationary neural activity, a condition which is fulfilled for afferent signals of varying strengths only close to criticality. In this view, the benefits of working vicinity of a second-order phase transition, such as signal enhancements, are not the underlying evolutionary drivers, but side effects of the requirement to keep the brain functional in first place. It is hence more appropriate to use the term 'self-regulated' in this context, instead of 'self-organized'.

description: More than 130 pure rotational transitions of $^{46}$TiO, $^{47}$TiO, $^{48}$TiO, $^{49}$TiO, $^{50}$TiO, and $^{48}$Ti$^{18}$O are recorded using a high-resolution mm-wave supersonic jet spectrometer in combination with a laser ablation source. For the first time a mass-independent Dunham-like analysis is performed encompassing rare titanium monoxide isotopologues, and are compared to results from high-accuracy quantum-chemical calculations. The obtained parametrization reveals for titanium monoxide effects due to deviations from the Born-Oppenheimer approximation. Additionally, the dominant titanium properties enable an insight into the electronic structure of TiO by analyzing its hyperfine interactions. Further, based on the mass-independent analysis, the frequency positions of the pure rotational transitions of the short lived rare isotopologue $^{44}$TiO are predicted with high accuracy, i.e., on a sub-MHz uncertainty level. This allows for dedicated radio-astronomical searches of this species in core-collapse environments of supernovae.

description: Bell inequalities rest on three fundamental assumptions: realism, locality, and free choice, which lead to nontrivial constraints on correlations in very simple experiments. If we retain realism, then violation of the inequalities implies that at least one of the remaining two assumptions must fail, which can have profound consequences for the causal explanation of the experiment. We investigate the extent to which a given assumption needs to be relaxed for the other to hold at all costs, based on the observation that a violation need not occur on every experimental trial, even when describing correlations violating Bell inequalities. How often this needs to be the case determines the degree of, respectively, locality or free choice in the observed experimental behavior. Despite their disparate character, we show that both assumptions are equally costly. Namely, the resources required to explain the experimental statistics (measured by the frequency of causal interventions of either sort) are exactly the same. Furthermore, we compute such defined measures of locality and free choice for any nonsignaling statistics in a Bell experiment with binary settings, showing that it is directly related to the amount of violation of the so-called Clauser-Horne-Shimony-Holt inequalities. This result is theory independent as it refers directly to the experimental statistics. Additionally, we show how the local fraction results for quantum-mechanical frameworks with infinite number of settings translate into analogous statements for the measure of free choice we introduce. Thus, concerning statistics, causal explanations resorting to either locality or free choice violations are fully interchangeable.

description: We address the problem of observables in generally invariant spacetime theories such as Einstein's general relativity. Using the refined notion of an event as a ``point-coincidence'' between scalar fields that completely characterise a spacetime model, we propose a generalisation of the relational local observables that does not require the existence of four everywhere invertible scalar fields. The collection of all point-coincidences forms in generic situations a four-dimensional manifold, that is naturally identified with the physical spacetime.

description: Scintillation detector is widely used for the particle detection in the field of particle physics. Particle detectors containing fluorine-19 ($^{19}\mathrm{F}$) are known to have advantages for Weakly Interacting Massive Particles (WIMPs) dark matter search, especially for spin-dependent interactions with WIMPs due to its spin structure. In this study, the scintillation properties of carbontetrafluoride ($\mathrm{CF_{4}}$) gas at low temperature was evaluated because its temperature dependence of light yield has not been measured. We evaluated the light yield by cooling the gas from room temperature (300K) to 263K. As a result, the light yield of $\mathrm{CF_{4}}$ was found to increase by $(41.0\pm4.0_{\rm stat.}\pm6.6_{\rm syst.})\%$ and the energy resolution was also found to improve at low temperature.

Orógeno Brasília Meridional

description: RESUMO Termocronologia é uma técnica que aplica sistemas químicos e isotópicos para extrair informações sobre a história termal de um terreno geológico. O conhecimento da história termal, associado a outras informações geológicas, permite estabelecer a duração/idade de processos geológicos-chave para o entendimento da evolução da história da Terra. Neste trabalho investigamos a evolução geotectônica do Orógeno Brasília Meridional, caracterizado por um sistema de nappes de diferentes gradientes metamórficos, originado durante a colisão entre as paleoplacas Paranapanema (margem ativa) e São Francisco (margem passiva) durante o Neoproterozóico. Os alóctones são denominados, das nappes superiores às inferiores, Nappe Socorro-Guaxupé, Sistema de Nappes Andrelândia (Oriental e Ocidental), Sistema de Nappes Carracas e Nappe Lima Duarte. A evolução geotectônica do orógeno é interpretada, atualmente, segundo dois modelos principais: (i) o Orógeno Brasília Meridional como a zona de interferência entre as faixas orogênicas Brasília e Ribeira e (ii) o modelo de evolução de migração do front orogênico em um evento único. Os dados obtidos neste trabalho e compilados da literatura indicam uma rápida exumação dos granulitos félsicos da Nappe Três Pontas-Varginha (Sistema de Nappes Andrelândia Ocidental - interior orogênico), evidenciada pelas idades em torno de 590 Ma obtidas por diferentes sistemas isotópicos com temperaturas de bloqueio distintas (U-Pb in situ em zircão, monazita e rutilo e 40Ar/39Ar em hornblenda e biotita). Também no interior orogênico, o lobo Guaxupé da Nappe Socorro-Guaxupé apresenta o mesmo padrão de exumação rápida, com cristalização de zircão soccer ball em ca. 608 Ma e idades 40Ar/39Ar em hornblenda e biotita entre 595-590 Ma. No Sistema de Nappes Andrelândia Oriental, idades 40Ar/39Ar em muscovita e biotita diminuem progressivamente em direção ao cráton São Francisco (555 Ma a 490 Ma), sugerindo resfriamento progressivo das nappes em direção ao craton. Por outro lado, no Sistema de Nappes Carrancas (frente orogênica), observase diminuição progressiva destas idades, de 541 Ma a 491 Ma, em direção à margem oriental do orógeno, sugerindo uma influência localizada da docagem do sistema orogênico Ribeira.

description: RESUMO – A interação de fluidos derivados de magmas carbonatíticos e alcalinos com suas encaixantes gera produtos caracteristicamente enriquecimentos em álcalis, em um processo denominado de fenitização (metassomatismo alcalino). Uma vez que esses fluidos outrora constituíam o magma, em estudos focados na evolução petrológica de magmas carbonatíticos e alcalinos, é importante que se considere também os fenitos. Na plataforma brasileira, são reconhecidas centenas de ocorrências alcalinas e alcalino-carbonatíticas de idade mesozóica, cuja gênese relaciona-se ao intenso magmatismo que se seguiu à quebra do Gondwana. Na maioria desses casos, fenitos restringem-se à zona de contato entre essas unidades e suas encaixantes (em geral proterozoicas). Algumas ocorrências particulares, no entanto, apresentam zonas fenitizadas em seu interior, particularmente entre carbonatitos e suas contrapartes ultramáficas/alcalinas. Nesse cenário, o presente projeto de pesquisa visa investigar as características dos fluidos fenitizadores e as reações ocorridas no contato entre rochas ultramáficas e carbonatitos em diferentes ocorrências brasileiras: complexos de Catalão, Tapira, Araxá (Alto Paranaíba) e Jacupiranga (Arco de Ponta Grossa). Enquanto o complexo de Jacupiranga caracteriza-se pela intercalação de níveis metassomáticos composicionalmente distintos (shells de anfibólio, flogopita e olivina), somente flogopititos foram gerados por fenitização nas ocorrências do Alto Paranaíba. Tendo em vista o caráter localizado desse processo, a abordagem pretendida envolve principalmente análises in situ (por microssonda eletrônica e laser ablation, LA ICP-MS) tanto dos minerais metassomáticos quanto dos protólitos ultramáficos. Análises de rocha total (química de rocha e isotopia) também serão ponderadas conforme o avanço do trabalho. A partir desses elementos, pretende-se responder questões como: (1) quais são as variações composicionais relacionadas às fases minerais das paragêneses metassomáticas? (2) quais as características e efeitos dos fluidos metassomáticos nas diferentes ocorrências? e (3) quais foram os elementos removidos e/ou adicionados do/ao magma carbonatítico?

description: The concept of social trust has attracted an attention of information processors/data scientists and information consumers / business firms. One of the main reasons for acquiring the value of SBD is to provide frameworks and methodologies using which the credibility of online social services users can be evaluated. These approaches should be scalable to accommodate large-scale social data. Hence, there is a need for well comprehending of social trust to improve and expand the analysis process and inferring credibility of social big data. Given the exposed environment's settings and fewer limitations related to online social services, the medium allows legitimate and genuine users as well as spammers and other low trustworthy users to publish and spread their content. This chapter presents an overview of the notion of credibility in the context of SBD. It also list an array of approaches to measure and evaluate the trustworthiness of users and their contents. Finally, a case study is presented that incorporates semantic analysis and machine learning modules to measure and predict users' trustworthiness in numerous domains in different time periods. The evaluation of the conducted experiment validates the applicability of the incorporated machine learning techniques to predict highly trustworthy domain-based users.

silicic volcanism

description: RESUMO Large Igneous Province (LIP) magmatism is thought to be responsible for global climate changes, which have led in some cases to major mass extinction events during the Phanerozoic. The breakup of Gondwana during the Lower Cretaceous produced the Paraná-Etendeka LIP, with up to 1,000,000 km3 of preserved volcanic rocks of dominantly basaltic composition and is one of the world’s largest LIPs. Silicic volcanic rocks are relatively abundant compared to other continental flood basalt provinces and are divided into Palmas (low-Ti) and Chapecó (high-Ti) types. The Valanginian is marked by a period of global-scale carbon cycle perturbation and biotic crisis, as evidenced by a positive δ13C excursion and Hg enrichment in the sedimentary record. Several studies have attempted to link the Paraná-Etendeka LIP volcanism with the Valanginian environmental event. However, such temporal correlation requires knowledge about the precise timing and duration of the volcanic activity, which is still poorly constrained in the Paraná Magmatic Province (PMP). Due to their relative stratigraphic positions, silicic volcanic rocks are good temporal markers to define the onset and duration of the magmatic activity in the province. Here, we significantly revise the timescales of magmatism and environmental impact of the Paraná Magmatic Province using high-precision U-Pb zircon geochronology. Our data demonstrate that a large amount of silicic magma from the Paraná LIP erupted very rapidly within an extremely narrow time interval of 0.12 ± 0.11 ky, providing evidence for short-lived (~100 ka) low-Ti silicic magmatism. Our new, more precise data agrees overall with older age information, but it also demonstrates that silicic magmatism of the PMP is younger than the Valanginian Weissert Episode that is dated at 135.22 Ma. A previous high-precision age from the Ourinhos trachydacite was re-visited and our new data reveal that the high-Ti silicic volcanic rocks in upper stratigraphic position are ~1.5 Myr younger than previously estimated. This further reinforces the hypothesis that the silicic volcanism of the Paraná Magmatic Province was likely not the triggering mechanism for the Valanginian δ13C excursion.

description: Inelastic neutron scattering (INS), electron spin (ESR) and nuclear magnetic resonance (NMR) measurements were employed to establish the origin of the strong magnetic signal in lightly hole-doped La_{1-x}Sr_xCoO_3, x=0.002. Both, INS and ESR low temperature spectra show intense excitations with large effective g-factors ~10-18. NMR data indicate the creation of extended magnetic clusters. From the Q-dependence of the INS magnetic intensity we conclude that the observed anomalies are caused by the formation of octahedrally shaped spin-state polarons comprising seven Co ions.

description: We model the high-energy emission that results from the interaction of relativistic particles with photons and matter in the cluster of galaxies Abell 3376. The presence of relativistic particles is inferred from the recently found radio relics in this cluster, being one of the most prominent examples of double opposite, giant ringlike radio structures. Assuming that diffusive shock acceleration takes place in the cluster regions where radio relics are observed, we calculate the spectral energy distribution resulting from the most relevant non-thermal processes, which are synchrotron radiation, inverse Compton scattering, relativistic Bremsstrahlung, and inelastic proton-proton collisions. In the context of our model, the major radiative component at high energies is inverse Compton scattering, which could reach luminosities L ~ 9x10^{41} erg/s in the energy range between ~ 1 MeV and 10 TeV. Hadronic interactions would yield a minor contribution to the overall non-thermal emission, but would dominate at ultra-high energies. The cluster Abell 3376 might be detectable at gamma-rays by HESS, GLAST satellite and future planned Cherenkov arrays.

description: The Integrated Information Theory provides a quantitative approach to consciousness and can be applied to neural networks. An embodied agent controlled by such a network influences and is being influenced by its environment. This involves, on the one hand, morphological computation within goal directed action and, on the other hand, integrated information within the controller, the agent's brain. In this article, we combine different methods in order to examine the information flows among and within the body, the brain and the environment of an agent. This allows us to relate various information flows to each other. We test this framework in a simple experimental setup. There, we calculate the optimal policy for goal-directed behavior based on the "planning as inference" method, in which the information-geometric em-algorithm is used to optimize the likelihood of the goal. Morphological computation and integrated information are then calculated with respect to the optimal policies. Comparing the dynamics of these measures under changing morphological circumstances highlights the antagonistic relationship between these two concepts. The more morphological computation is involved, the less information integration within the brain is required. In order to determine the influence of the brain on the behavior of the agent it is necessary to additionally measure the information flow to and from the brain.

description: Effective verbal communication is crucial in human-robot collaboration. When a robot helps its human partner to complete a task with verbal instructions, referring expressions are commonly employed during the interaction. Despite many studies on generating referring expressions, crucial open challenges still remain for effective interaction. In this work, we discuss some of these challenges (i.e., using contextual information, taking users' perspectives, and handling misinterpretations in an autonomous manner).

description: Derivations of a noncommutative algebra can be used to construct differential calculi, the so-called derivation-based differential calculi. We apply this framework to a version of the Moyal algebra ${\cal{M}}$. We show that the differential calculus, generated by the maximal subalgebra of the derivation algebra of ${\cal{M}}$ that can be related to infinitesimal symplectomorphisms, gives rise to a natural construction of Yang-Mills-Higgs models on ${\cal{M}}$ and a natural interpretation of the covariant coordinates as Higgs fields. We also compare in detail the main mathematical properties characterizing the present situation to those specific of two other noncommutative geometries, namely the finite dimensional matrix algebra $M_n({\mathbb{C}})$ and the algebra of matrix valued functions $C^\infty(M)\otimes M_n({\mathbb{C}})$. The UV/IR mixing problem of the resulting Yang-Mills-Higgs models is also discussed.

description: The coupling between cell-free massive multiple-input multiple-output (MIMO) systems operating at millimeter-wave (mmWave) carrier frequencies and user mobility is considered in this paper. First of all, a mmWave channel is introduced taking into account the user mobility and the impact of the channel aging. Then, three beamforming techniques are proposed in the considered scenario, along with a dynamic user association technique (handover): starting from a user-centric association between each mobile device and a cluster of access points (APs), a rule for updating the APs cluster is formulated and analyzed. Numerical results reveal that the proposed beamforming and user association techniques are effective in the considered scenario.

description: We theoretically describe the behavior of a terahertz nano-oscillator based on an anisotropic antiferromagnetic dynamical element driven by spin torque. We consider the situation when the polarization of the spin-current is perpendicular to the external magnetic field applied along the anisotropy easy-axis. We determine the domain of the parametric space (field, current) where the oscillator demonstrates chaotic dynamics. Characteristics of the chaotic regimes are analyzed using conventional techniques such as spectra of the Lyapunov exponents. We show that the threshold current of the chaos appearance is particularly low in the vicinity of the spin-flop transition. In this regime, we consider the mechanism of the chaos appearance in detail when the field is fixed and the current density increases. We show that the appearance of chaos is preceded by a regime of quasiperiodic dynamics on the surface of a two-frequency torus arising in phase space as a result of the Neimark-Sacker bifurcation.

description: The nearby face-on spiral galaxy M101 has been observed with the Far-Infrared Surveyor (FIS) onboard AKARI. The far-infrared four-band images reveal fine spatial structures of M101, which include global spiral patterns, giant HII regions embedded in outer spiral arms, and a bar-like feature crossing the center. The spectral energy distribution of the whole galaxy shows the presence of the cold dust component (18 K) in addition to the warm dust component (55 K). The distribution of the cold dust is mostly concentrated near the center, and exhibits smoothly distributed over the entire extent of the galaxy, whereas the distribution of the warm dust indicates some correlation with the spiral arms, and has spotty structures such as four distinctive bright spots in the outer disk in addition to a bar-like feature near the center tracing the CO intensity map. The star-formation activity of the giant HII regions that spatially correspond to the former bright spots is found to be significantly higher than that of the rest of the galaxy. The latter warm dust distribution implies that there are significant star-formation activities in the entire bar filled with molecular clouds. Unlike our Galaxy, M101 is a peculiar normal galaxy with extraordinary active star-forming regions.

Diabatic description of bottomoniumlike mesons

description: We apply the diabatic approach, specially suited for a QCD based study of conventional (quark-antiquark) and unconventional (quark-antiquark + meson-meson) meson states, to the description of hidden-bottom mesons. A spectral analysis of the $I=0$, $J^{++}$ and $1^{--}$ resonances with masses up to about $10.8$ GeV is carried out. Masses and widths of all the experimentally known resonances, including conventional and unconventional states, can be well reproduced. In particular, we predict a significant $B\bar{B}^{\ast}$ component in $Υ(10580)$. We also predict the existence of a not yet discovered unconventional $1^{++}$ narrow state, with a significant $B_{s}\bar{B}_{s}^{\ast}$ content making it to decay into $Υ(1S)ϕ$, whose experimental discovery would provide definite support to our theoretical analysis.

Testing the Accuracy of Synthetic Stellar Libraries

description: In the present work we compare in detail some of the major theoretical libraries with observations, aiming at detecting weaknesses and strengths from the stellar population modelling point of view. We compared model predictions and observations for broad- band colours and for high resolution spectral features. Concerning the broad-band colours, we measured the stellar colour given by three recent sets of model atmospheres and flux distributions(Castelli & Kurucz 2003; Gustafsson et al. 2003; Brott & Hauschildt 2005), and compared them with a recent UBVRIJHK calibration (Worthey & Lee 2007). We found that the models can reproduce with reasonable accuracy the stellar colours for a fair interval in effective temperatures and gravities. The exceptions are: 1) the U-B colour, where the models are typically redder than the observations, and; 2) the very cool stars in general (V-K > ~3).Concerning the high resolution features, we measured 35 spectral indices defined in the literature on three high resolution synthetic libraries (Coelho et al. 2005; Martins et al. 2005; Munari et al. 2005), and compared them with the observed measurements given by three empirical libraries (Valdes et al.2004; Sanchez-Blazquez et al. 2006; Prugniel & Soubiran 2001). We found that the direct comparison between models and observations is not a simple task, given the uncertainties in parameter determinations of empirical libraries. Taking that aside, we found that in general the three libraries present similar behaviours and systematic deviations. For stars with Teff < 7000K, the library by Coelho et al. (2005) is the one with best average performance. We detect that lists of atomic and molecular line opacities still need improvement, specially in the blue region of thespectrum, and for the cool stars (Teff < ~4500K).

Diagnosis. The new subgenus Hyporhoe differs from the nominative subgenus Catarhoe in the appearance by the cylindric male flagellum, by the weakly sinuous and somewhat blurred transverse lines on the wings; in the wing venation by the short proximal areole on the forewing and lacking the vein A2 on the hindwing; in the male genitalia by the obtuse distal process of the costa of valva, by presence of numerous small spines on the costa of valva, and by lacking cornuti on the vesica of phallus; in the female genitalia by the presence of a relatively narrow and strictly transverse ring of sclerotisation of the ductus bursae at the base of the corpus bursae.
Description. See description of the species.
Etymology. The name Hyporhoe is formed by the combination of Ancient Greek prefix ὑπο- (hupó—under, sub-, hypo-) and noun ῥοή (feminine gender) (rhoḗ—a river, a stream).

Supersymmetric moduli of the SU(2) x R linear dilaton background and NS5-branes

Year: 2008
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study several classes of marginal deformations of the conformal field theory SU(2) x R. This theory describes the near-horizon region of a stack of parallel and coincident NS5-branes and is related holographically to little string theory. We investigate the supersymmetry properties of these deformations and we elucidate their role in the context of holography. The conformal field theory moduli space contains "non-holographic" operators that do not seem to have a simple interpretation in little string theory. Subsequently, we analyze several NS5-brane configurations in terms of SU(2) x R deformations. We discuss in detail interesting phenomena, like the excision of the strong coupling region associated with the linear dilaton and the manifestation of the symmetries of an NS5-brane setup in the deforming operators. Finally, we present a class of conformally hyperkaehler geometries that arise as "non-holographic" deformations of SU(2) x R.

Pion electromagnetic form factor, perturbative QCD, and large-Nc Regge models

Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We present a construction of the pion electromagnetic form factor where the transition from large-Nc Regge vector meson dominance models with infinitely many resonances to perturbative QCD is built in explicitly. The construction is based on an appropriate assignment of residues to the Regge poles, which fulfills the constraints of the parton-hadron duality and perturbative QCD. The model contains a slowly falling off non-perturbative contribution which dominates over the perturbative QCD radiative corrections for the experimentally accessible momenta. The leading order and next-to-leading order calculations show a converging pattern which describes the available data within uncertainties, while the onset of asymptotic QCD takes place at extremely high momenta, Q ~ 10^3-10^4 GeV. The method can be straightforwardly extended to study other form factors where the perturbative QCD result is available.

description: Time-dependent soliton solutions are explicitly derived in a five-dimensional theory endowed with one (warped) extra-dimension. Some of the obtained geometries, everywhere well defined and technically regular, smoothly interpolate between two five-dimensional anti-de Sitter space-times for fixed value of the conformal time coordinate. Time dependent solutions containing both topological and non-topological sectors are also obtained. Supplementary degrees of freedom can be also included and, in this case, the resulting multi-soliton solutions may describe time-dependent kink-antikink systems.
