description: The broad high-energy spectral component in blazars is usually attributed to various inverse Compton scattering processes in the relativistic jet, but has not been clearly identified in most cases due to degeneracies in physical models. AP Librae, a low-synchrotron-peaking BL Lac object (LBL) detected in 2015 by H.E.S.S. at very high energies (VHE; $>$ 0.5 TeV), has an extremely broad high-energy spectrum, covering $\sim$ 9 decades in energy. Standard synchrotron self-Compton models generally fail to reproduce the VHE emission, which has led to the suggestion that it might arise not from the blazar core, but on kiloparsec scales from inverse Compton scattering of cosmic microwave background (CMB) photons by a still-relativistic jet (IC/CMB). IC/CMB models for the TeV emission of AP Librae in prior works have implied a high level of infrared emission from the kpc-scale jet. With newly obtained Hubble Space Telescope imaging, we obtain a deep upper limit on the kpc-scale jet emission at 1.6 $μ$m, well below the expected level. High-resolution ALMA imaging in bands 3-9 reveals a residual dust disk signature after core subtraction, with a clearly thermal spectrum, and an extent ($\sim$500 pc) which matches with a non-jet residual emission seen after PSF subtraction in our 1.6 $μ$m HST imaging. We find that the unusually broad GeV and VHE emission in AP Librae can be reproduced through the combined IC scattering of photons from the CMB and the dust disk, respectively, by electrons in both the blazar core and sub-kpc jet.

description: In this paper we present a scalable algorithm for performing a subset of OWL reasoning over web data using a rule-based approach to forward-chaining; in particular, we identify the problem of ontology hijacking: new ontologies published on the Web redefining the semantics of existing concepts resident in other ontologies. Our solution introduces consideration of authoritative sources. We present the results of applying our methods on a re-crawl of the billion triple challenge dataset.

description: We examine the common belief that the $N_pN_n$ scheme is manifested as a direct consequence of the valence proton-neutron interaction which has proven to be a dominant factor in developing collectivity in nuclei. We show that the simplification of the $N_pN_n$-plot of the lowest $2^+$ excitation energy is introduced merely because the excitation energy always decreases when the valence nucleon number becomes larger.

description: We present the radio properties of optically selected quasars with $z\geq3$. The complete sample consists of 102 quasars with a flux density level $S_{1.4}\geq100$ mJy in a declination range -35$^{\circ}$ $\leq$ Dec $\leq$ +49$^{\circ}$. The observations were obtained in 2017-2020 using the radio telescope RATAN-600. We measured flux densities at six frequencies 1.2, 2.3, 4.7, 8.2, 11.2, and 22 GHz quasi-simultaneously with uncertainties of 9-31 %. The detection rate is 100, 89, and 46 % at 4.7, 11.2, and 22 GHz, respectively. We have analysed the averaged radio spectra of the quasars based on the RATAN and literature data. We classify 46 % of radio spectra as peaked-spectrum, 24 % as flat, and none as ultra-steep spectra ($α\leq-1.1$). The multifrequency data reveal that a peaked spectral shape (PS) is a common feature for bright high-redshift quasars. This indicates the dominance of bright compact core emission and the insignificant contribution of extended optically thin kpc-scale components in observed radio spectra. Using these new radio data, the radio loudness $\log~R$ was estimated for 71 objects with a median value of 3.5, showing that the majority of the quasars are highly radio-loud with $\log~R>2.5$. We have not found any significant correlation between $z$ and $α$. Several new megahertz-peaked spectrum (MPS) and gigahertz-peaked spectrum (GPS) candidates are suggested. Further studies of their variability and additional low-frequency observations are needed to classify them precisely.

The Quebec Winter Carnival of 1894 : the transformation of the city and the festival in the nineteenth century
Creators: name: Abbott, Frank Albert
Publisher: name: University of British Columbia
Year: 2010

description: The ambiguous nature and the importance of ancient traditions adapting to modernization are very evident in the celebration of the winter carnivals held in Montreal between 1883 and 1889 and especially in Quebec City in 1894. In looking at the motivations of their organizers, it is possible to see a primarily economic goal: the attraction of large numbers of American tourists to help the local economy in the slow winter season by offering to them "cultural" spectacles of French and English Canada. According to the newspapers of the period, these new carnivals had no connection at all with the older cyclical and religious celebration of Carnival-Lent-Easter which were well-known and celebrated with enthusiasm in New France from the seventeenth century onwards. In fact the opposite was true. These events were seen as occasions for the amateur athletic clubs of the French and especially the English-speaking middle class of Quebec to put on spectacles of their winter sports like curling, snowshoeing and hockey. Along with this went the expectation of decorous behaviour within the limits of Victorian morality and an end to the traditional public drunkenness and boisterous behaviour traditionally associated with such occasions. The centrepiece of this event was the evening torch-light parade in and around the large ice palace, a tradition which the English speaking organizers of the five Montreal carnivals of the 1880's had borrowed from winter festivals of the Imperial Russian court. Paradoxically, this has survived to become one of most famous symbols of the present Carnaval de Quebec. The participation of middle class French Canadians and even the tacit support of the Catholic Church, one of the most persistent foes of the older carnival celebrations, both contributed immeasurably to the success of the new festival. This can be explained by three related phenomena: 1) A change in social mores in general between the beginning and the end of the nineteenth century gave the Church a large voice over the lives of French Canadians. 2) A greater process of regulation of the society, and especially the city, was reflected in and even responsible for the disappearance of several old community festivals of the past like the carnival. It is not yet possible to say conclusively whether the authorities suppressed these old festivals or whether the public simply abandoned them, though it appears to be a combination of both. 3) The economic transformation of the city of Quebec from a commercial centre to an industrial city, with the consequent social changes. Thus the study of the carnival raises cultural and social questions. By studying the history of the changes in the observance of the carnival and in who observed its celebration, it is possible to understand a little more about the mentality of the urban population of the time and to begin to understand their responses to the other changes taking place in the society around them.
The role of proactive coping strategies and perceived health status for Social well-being and life-project in old age.

description: The latter part of the 20th century was a period characterized by a fundamental  demographic transition of western society. This substantial and structural demographic change proposes several challenges to contemporary society and fosters the emergence of new issues and challenges. Among these, none is more crucial than the comprehension of the mechanisms and the processes that lead people to positive aging. Rowe and Kahn’s model of successful aging highlights the interplay between social engagement with life, health, and functioning for a positive aging experience. Other systemic models of successful aging (Kahana et al., 1996; 2003; Stevernik et al., 2006) emphasize the role of internal and external resources for attaining positive aging. Among these, the proactive coping strategies are indicated as important  active strategies for avoiding the depletion of resources, counterbalancing the declines and maintaining social and civic involvement.
The study has analyzed the role of proactive coping strategies for two facets of positive aging, the experience of a high social well-being and the presence of personal projects in fundamental life domains. As expected, the proactive coping strategies, referred to as the active management of the environment, the accumulation of resources and the actualization of human potentials are confirmed as positive predictors of high level of social well-being and of many personal projects focused on family, culture, leisure time, civic and social participation. Perceived health status give a significant contribution only to the possession of many personal projects. Gender and level of school education give also a significant contribution to these two dimensions of positive aging, highlighting how positive aging is rooted not only in the possession of personal resources, but also in historical models of education and in positive longitudinal chains related to early development.

description: Superconductivity and magnetism in the non-centrosymmetric heavy fermion compound CePt$_3$Si and related materials are theoretically investigated. Based on the randam phase approximation (RPA) analysis for the extended Hubbard model we describe the helical spin fluctuation induced by the Rashba-type anti-symmetric spin-orbit coupling and identify the two stable superconducting phases with either dominantly p-wave ($s$ + $P$-wave) or d-wave ($p$ + $D$ + $f$-wave) symmetry. The influcnce of the coexistent anti-ferromagnetic order is investigated in both states. The SC order parameter, quasiparticle density of state, NMR $1/T_{1}T$, specific heat, anisotropy of $H_{\rm c2}$ and possible multiple phase transitions are discussed in details. The comparison with experimental results indicates that the $s$ + $P$-wave superconducting state is likely realized in CePt$_3$Si.

Year: 2017

description: The present study is part of a process of reflection on the relation, relevance and intervention of the body in the musical performance. Considering that the entire performative process demands a unified participation of the instrument, mind and body, it is necessary to deepen the reflection about the perceptions, knowledge and convictions of the faculty, student and professional in the field of music. Given the complementarity between body and performative dimension, it is fundamental to consider the quality that this relationship assumes in the learning processes. Given the objectives of the study, we opted for a methodological conception that allows the articulation of qualitative and quantitative approaches, fundamental to understand, describe and interpret the different representations / perceptions of the participants. In this way, the questionnaire survey (Questionnaire I and II) was directed to the faculty and students of the area of music of the Federal University of Rio de Janeiro and researchers of the Brazilian Association of Musical Performance. The obtained results show that the differentiated coordination and the body movements assume an essential condition for the musician and his performance.

description: Parallel to the discussion of conceptual issues regarding health, some pedagogical proposals and curricular conceptions were developed in Physical Education in Brazil in the 80’s, which represented a breakthrough in the academic field. Meanwhile, a detachment of most of the proposals, regarding health as a teaching subject in school, came over. So, we ask: nowadays would the state curriculum proposals indicating health as a theme for Physical Education? Under what health perspective would be grounded these documents? How has this theme been translated to Physical Education lessons? To seek for answers, we conducted a survey in the curriculum proposals for Physical Education in northeast of Brazil. We use the thematic content analysis and realized that health is a prime topic in some proposals at the same level of corporal practices, being structured by themes, teaching content and content underlying other topics of corporal practices. We noted that both in intentions and proposals, health revolves predominantly around the healthy habits in anatomical physiological perspective, as, paradoxically, intentions and proposals share the concept of health in a public health perspective.

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

description: Particle number fluctuations are studied in the ideal pion gas approaching Bose-Einstein condensation. Two different cases are considered: Bose condensation of pions at large charge densities $ρ_Q$ and Bose condensation at large total densities of pions $ρ_π$. Calculations are done in grand canonical, canonical and microcanonical ensembles. At high collision energy, in the samples of events with a fixed number of all pions, $N_π$, one may observe a prominent signal. When $N_π$ increases the scaled variances for particle number fluctuations of both neutral and charged pions increase dramatically in the vicinity of the Bose-Einstein condensation line. As an example, the estimates are presented for $p+p$ collisions at the beam energy of 70 GeV.

description: A Pixelized Photon Detector (PPD) is a generic name for the semiconductor devices operated in the Geiger-mode, such as Silicon PhotoMultiplier and Multi-Pixel Photon Counter, which has high photon counting capability. While the internal mechanisms of the PPD have been intensively studied in recent years, the existing models do not include the avalanche process. We have simulated the multiplication and quenching of the avalanche process and have succeeded in reproducing the output waveform of the PPD. Furthermore our model predicts the existence of dead-time in the PPD which has never been numerically predicted. For serching the dead-time, we also have developed waveform analysis method using deconvolution which has the potential to distinguish neibouring pulses precisely. In this paper, we discuss our improved model and waveform analysis method.

description: We investigate the presence of an acoustic-quasi-elastic interaction contribution in the IXS spectra of liquid water at 301K using inelastic x-ray scattering with sub-meV energy resolution at momentum transfers 0.77<=Q<=4.20 /nm. The contribution appears due to the overlap the acoustic mode with the tail the quasi-elastic mode and is fully consistent with hydrodynamic theory. Incorporating this interaction allows us to describe the dynamic structure factor, S(Q,w), without introducing an extra mode, and may help explain earlier contradictory interpretations. The sound velocity, and relative intensity of the quasi-elastic and acoustic mode, plateau for Q>2/nm at values consistent with a viscoelastic generalization of the Landau-Placzek relation.

Controlling for individual heterogeneity in longitudinal models, with applications to student achievement

Year: 2007

description: Longitudinal data tracking repeated measurements on individuals are highly valued for research because they offer controls for unmeasured individual heterogeneity that might otherwise bias results. Random effects or mixed models approaches, which treat individual heterogeneity as part of the model error term and use generalized least squares to estimate model parameters, are often criticized because correlation between unobserved individual effects and other model variables can lead to biased and inconsistent parameter estimates. Starting with an examination of the relationship between random effects and fixed effects estimators in the standard unobserved effects model, this article demonstrates through analysis and simulation that the mixed model approach has a ``bias compression'' property under a general model for individual heterogeneity that can mitigate bias due to uncontrolled differences among individuals. The general model is motivated by the complexities of longitudinal student achievement measures, but the results have broad applicability to longitudinal modeling.

description: We study the spin Coulomb drag in a quasi-two-dimensional electron gas beyond the random phase approximation (RPA). We find that the finite transverse width of the electron gas causes a significant reduction of the spin Coulomb drag. This reduction, however, is largely compensated by the enhancement coming from the inclusion of many-body local field effects beyond the RPA, thereby restoring good agreement with the experimental observations by C. P. Weber \textit{et al.}, Nature, \textbf{437}, 1330 (2005).

Geant4 provides an optical physics process category, allowing the simulation of the production and propagation of light. Its capabilities are well tailored for the simulation of optics systems namely in cosmic-rays experiments based in the detection of Cherenkov and fluorescence light. The use of Geant4 as an engineering tool for the optics design and simulation of Fresnel lens systems is discussed through a specific example.

The art of dialogue in The sacred fount by Henry James and Martereau by Nathalie Sarraute
Creators: name: Burns, Nancy Jane
Publisher: name: University of British Columbia
Year: 2010

description: Conversation in Martereau is largely an affair of platitudinous and banal statements masking the antagonistic content of the subconversation. Consisting mainly of dialogue, The Sacred Fount presents the polished talk that evolves as the characters attempt to unravel an enigma. Though the aims of both authors are very different in many respects, Sarraute and James share a common fascination with the way in which language constitutes a means of dissimulation rather than communication. Dialogue is consequently a problematic element of both novels, registering the drama of the unspoken through commonplace remarks, echoes, and pauses which suggest the presence of a discrete psychological reality. In seeking to renew the dialogue form in the novel, both authors depict dramatic situations in which speech functions as a means of manipulation. The nature of reported discourse in the two novels will be discussed using Jakobson's six-part model of communication, examining in detail the constitutive elements of Jamesian and Sarrautian conversation. The stylistic traits of each author will be considered as a function of the specific constraints of indirect and duplicitous communication. In juxtaposition to the "trompe-l'oeil,” or illusory, reality presented in the dialogue, a pattern of repetitive social exchanges becomes apparent as characters make contact in conversation. While James is most interested in the way in which covert strategies are expressed in speech through implication and allusion, Sarraute examines the effect of speech upon the listener: in both cases, indirect language is perceived as accomplishing certain acts and producing unpredictable effects. The interplay between hidden strategies in James or tropistic activity in Sarraute and dialogue becomes more evident in the narrative discourse, which develops the suggestions and possibilities inherent in the reported speech. The polyphony of the dialogue form is dominated in the narrative discourse by an obsessive observer, who, in the case of The Sacred Fount, is patently unreliable, or at best, unduly sensitive, as in Martereau. An examination of the various forms of narrative intervention, from sporadic inquit interpolations to sustained commentary, suggests the contribution of each novelist in innovating the dialogue form. The post-Victorian experimental novel of Henry James is considered in relation to the nouveau roman, the latter illuminating the autonomous play of language in The Sacred Fount, which documents—if not "l'aventure d'une ecriture"—the adventure of the creative imagination. Placed in parallel with the more traditional dialogue form, Sarraute's work is seen to exemplify the subconscious impulsions generated by the nature of the dialogue. Each author sheds light on the artistic project of the other: incipient, subconscious motivations are brought to light in the Jamesian text, while reported speech is revealed as having a major significance in Sarraute's fiction.

description: We investigate the role of jet and shower parton broadening by the strong colour field in the $Δη$-$Δϕ$ correlation of high $p_T$ particles. When anisotropic momentum broadening ($Δp_z > Δp_T$) is given to jet and shower partons in the initial stage, a ridge-like structure is found to appear in the two hadron correlation. The ratio of the peak to the pedestal yield is overestimated.

description: Phase separation in the nanometer- to micrometer-scale is characteristic for correlated materials, for example, high temperature superconductors, colossal magnetoresistance manganites, Mott insulators, etc. Resolving the electronic structure with spatially-resolved information is critical for revealing the fundamental physics of such inhomogeneous systems yet this is challenging experimentally. Here by using nanometer- and micrometer-spot angle-resolved photoemission spectroscopies (NanoARPES and MicroARPES), we reveal the spatially-resolved electronic structure in the stripe phase of IrTe$_2$. Each separated domain shows two-fold symmetric electronic structure with the mirror axis aligned along 3 equivalent directions, and 6$\times$1 replicas are clearly identified. Moreover, such electronic structure inhomogeneity disappears across the stripe phase transition, suggesting that electronic phase with broken symmetry induced by the 6$\times$1 modulation is directly related to the stripe phase transition of IrTe$_2$. Our work demonstrates the capability of NanoARPES and MicroARPES in elucidating the fundamental physics of phase-separated materials.

description: Immune system and cell metabolism have been interacted constantly, by synthesis and release of immunomodulatory proteins, recognized as cytokines, in order to maintain the body homeostasis. The “crosstalk” between systems has been widely spread in several areas of knowledge, mainly in the health field, as Immunometabolism. Diseases of the 21st century, which affect world populations, are characterized by inflammatory processes favoring the worsening of the illness itself and the installation of other co-morbidities. In general, the inflammatory response is associated with poor diet and physical inactivity, which modify the metabolic dynamics among cytokines, fatty acids and endotoxin culminating in reaction cascades, activating gene transcription factors, such as NF-kB. Furthermore, regular physical exercise is widely recommended as a powerful tool at the prevention and treatment of several metabolic diseases in virtue of anti-inflammatory and anti-atherogenic capacity, through anti-inflammatory myokine production, such as IL-6, from the stimuli generated by muscle contraction and proteins and gene transcription factors activation, as PPAR, which increase the anti-inflammatory response. Thus, the purpose of this review is to contextualize and disseminate knowledge about an emerging area, the Immunometabolism, featuring its function and performance in the illness and health fields by physical exercise.

description: Stochastic evolution equations in Banach spaces with unbounded nonlinear drift and diffusion operators driven by a finite dimensional Brownian motion are considered. Under some regularity condition assumed for the solution, the rate of convergence of various numerical approximations are estimated under strong monotonicity and Lipschitz conditions. The abstract setting involves general consistency conditions and is then applied to a class of quasilinear stochastic PDEs of parabolic type.

description: The spine has a direct influence on postural alignment and movement of the whole body. Lumbar muscles constitute a critical element in trunk performance while weakness of these muscles has been associated with low back pain. Hence, strength profiling of trunk muscles is clinically significant. The objective of this research was to determine, by means of isokinetic dynamometry, peak moment (PM) values during isokinetic concentric and eccentric efforts of trunk flexion and extension in sedentary asymptomatic individuals. The sample consisted of 100 asymptomatic sedentary volunteers, fifty from each sex, aging 22.2 ± 3.3 years old. The sample underwent concentric and eccentric isokinetic assessment of the trunk flexor and extensor muscles at an angular velocity of 60 degrees/sec for each mode of contraction. The mean concentric PM for trunk flexion and extension were 139.5 and 166.6 Nm, respectively, while the respective values for the eccentric efforts were 188.8 and 221.2 Nm. The PM flexion/extension ratio was 0.87 and 0.89 for the concentric and eccentric efforts, respectively. These values of concentric and eccentric PM and PM ratio will serve as comparison parameters for future research, as well as for the assessment of symptomatic patients, and to help in the creation of the trunk muscle rebalance protocols.

description: Developing artificial Intelligence (AI) technology has become a business of power. AI innovation is increasingly centralized in a few large companies – mainly, Google, Facebook, and Apple.1 Specialized data scientists - the backbone of these institutions - understand how AI functions, further creating a power dynamic between the layperson and the corporatized specialist. In the age of COVID-19, we have all become more reliant on technology companies and innovations to fulfill the needs of our new digital lives. We have little choice but to trust them in developing the AI technologies of the future.

description: The past two decades have witnessed a surge of interest in borrowing tools from quantum information theory to investigate quantum phase transitions (QPTs). The best known examples are entanglement measures whose nonanalyticities at critical points were tied to QPTs in a plethora of physical models. Here, focusing on the XXZ model, we show how QPTs can be revealed through the quantum steering ellipsoid (QSE), which is a geometric tool capable of characterizing both the strength and type of quantum correlations between two subsystems of a compound system. We find that the QSE associated with the XXZ model changes in shape with the QPTs, that is, it is a needle in the ferromagnetic phase, an oblate spheroid in the gapless phase, and a prolate spheroid in the antiferromagnetic phase. This finding offers an example demonstrating the intriguing possibility of unveiling QPTs in a geometrically visible fashion. Some connections between our results and previous ones are discussed.

description: Entropic uncertainty relations place nontrivial lower bounds to the sum of Shannon information entropies for noncommuting observables. Here we obtain a novel lower bound on the entropy sum for general pairs of observables in finite-dimensional Hilbert space, which improves on the best bound known to date [Maassen and Uffink, Phys. Rev. Lett. 60, 1103 (1988)] for a wide class of observables. This result follows from another formulation of the uncertainty principle, the Landau-Pollak inequality, whose relationship to the Maassen-Uffink entropic uncertainty relation is discussed.

description: In many cases, the computation of a neural system can be reduced to a receptive field, or a set of linear filters, and a thresholding function, or gain curve, which determines the firing probability; this is known as a linear/nonlinear model. In some forms of sensory adaptation, these linear filters and gain curve adjust very rapidly to changes in the variance of a randomly varying driving input. An apparently similar but previously unrelated issue is the observation of gain control by background noise in cortical neurons: the slope of the firing rate vs current (f-I) curve changes with the variance of background random input. Here, we show a direct correspondence between these two observations by relating variance-dependent changes in the gain of f-I curves to characteristics of the changing empirical linear/nonlinear model obtained by sampling. In the case that the underlying system is fixed, we derive relationships relating the change of the gain with respect to both mean and variance with the receptive fields derived from reverse correlation on a white noise stimulus. Using two conductance-based model neurons that display distinct gain modulation properties through a simple change in parameters, we show that coding properties of both these models quantitatively satisfy the predicted relationships. Our results describe how both variance-dependent gain modulation and adaptive neural computation result from intrinsic nonlinearity.
