description: The energetic balance of the Standard Solar Model (SSM) results from an equilibrium between nuclear energy production, energy transfer, and photospheric emission. In this letter, we derive an order of magnitude of several % for the loss of energy in kinetic energy, magnetic energy, and X or UV radiation during the whole solar lifetime from the observations of the present Sun. We also estimate the mass loss from the observations of young solar analogs which could reach up to 30% of the current mass. We deduce new models of the present Sun, their associated neutrino fluxes, and their internal sound-speed profile. This approach sheds quantitative lights on the disagreement between the sound speed obtained by helioseismology and the sound speed derived from the SSM including the updated photospheric CNO abundances, based on recent observations. We conclude that about 20% of the present discrepancy could come from the incorrect description of the early phases of the Sun, its activity, its initial mass and mass-loss history. This study has obvious consequences on the solar system formation and the early evolution of the closest planets.

description: The Hagedorn temperature, T_H is determined from the number of hadronic resonances including all mesons and baryons. This leads to a stable result T_H = 174 MeV consistent with the critical and the chemical freeze-out temperatures at zero chemical potential. We use this result to calculate the speed of sound and other thermodynamic quantities in the resonance hadron gas model for a wide range of baryon chemical potentials following the chemical freeze-out curve. We compare some of our results to those obtained previously in other papers.

description: In the search for the mechanism of high-temperature superconductivity, intense research has been focused on the evolution of the spin excitation spectrum upon doping from the antiferromagnetic insulating to the superconducting states of the cuprates. Because of technical limitations, the experimental investigation of doped cuprates has been largely focused on low-energy excitations in a small range of momentum space. Here we use resonant inelastic x-ray scattering to show that a large family of superconductors, encompassing underdoped YBa$_2$Cu$_4$O$_8$ and overdoped YBa$_2$Cu$_3$O$_{7}$, exhibits damped spin excitations (paramagnons) with dispersions and spectral weights closely similar to those of magnons in undoped cuprates. %The results are in excellent agreement with the spin excitations obtained by exact diagonalization of the $\bf t-J$ Hamiltonian on finite-sized clusters. The comprehensive experimental description of this surprisingly simple spectrum permits quantitative tests of magnetic Cooper pairing models. A numerical solution of the Eliashberg equations for the magnetic spectrum of YBa$_2$Cu$_3$O$_{7}$ reproduces its superconducting transition temperature within a factor of two, a level of agreement comparable to Eliashberg theories of conventional superconductors.

description: In light of recent political developments in Western democracies, several political commentators and theorists have argued that encouraging anger in citizens may contribute to social justice and should therefore constitute an aim of civic education. In this article, Douglas Yacek investigates these claims in depth. In doing so, he expands on previous work on the political and educational significance of anger — particularly by critical and “agonistic” theorists of civic education — in two distinct ways. First, Yacek explores the psychological costs and benefits of cultivating student anger. Second, he examines the potential cultural effects of anger in Western democratic societies. While sympathetic to the defenses of anger that have been recently offered in political and educational theory, Yacek concludes that we should be cautious about embracing anger in civic education. In particular, he argues that anger involves serious psychological risk, may exacerbate the social problems that it sets out to solve, and can lead to a disposition of adversarial and politically counterproductive closed-mindedness. In the closing sections, Yacek suggests that experiences he calls “civic epiphanies” are central to cultivating a politically beneficial form of open-mindedness, and argues that such experiences should therefore be encouraged in civic education.

description: This paper addresses the statistical significance of structures in random data: Given a set of vectors and a measure of mutual similarity, how likely does a subset of these vectors form a cluster with enhanced similarity among its elements? The computation of this cluster p-value for randomly distributed vectors is mapped onto a well-defined problem of statistical mechanics. We solve this problem analytically, establishing a connection between the physics of quenched disorder and multiple testing statistics in clustering and related problems. In an application to gene expression data, we find a remarkable link between the statistical significance of a cluster and the functional relationships between its genes.

description: We investigate the possibility that dark matter is a mixture of two non-interacting perfect fluids, with different four-velocities and thermodynamic parameters. The two-fluid model can be described as an effective single anisotropic fluid, with distinct radial and tangential pressures. The basic equations describing the equilibrium structure of the two-fluid dark matter model, and of the tangential velocity of test particles in stable circular orbits, are obtained for the case of a spherically symmetric static geometry. By assuming a non-relativistic kinetic model for the dark matter particles, the density profile and the tangential velocity of the dark matter mixture are obtained by numerically integrating the gravitational field equations. The cosmological implications of the model are also briefly considered, and it is shown that the anisotropic two-fluid model isotropizes in the large time limit.

description: We report on experiments investigating quantum transport and band interferometry of an atomic Bose-Einstein condensate in an optical lattice with a two-band miniband structure, realized with a Fourier-synthesized optical lattice potential. Bloch-Zener oscillations, the coherent superposition of Bloch oscillations and Landau-Zener tunneling between the two bands are observed. When the relative phase between paths in different bands is varied, an interference signal is observed, demonstrating the coherence of the dynamics in the miniband system. Measured fringe patterns of this Stückelberg interferometer allow to interferometrically map out the band structure of the optical lattice over the full Brillouin zone.

description: Lung cancer is the leading cancer according to the World Health Organization (WHO), resulting in highest death rate worldwide due to the high level of metastasis. Hence, the drugs that protect from metastasis either as an adjuvant or a primary therapeutic agent may help to reduce the death rate. In this study, All Trans Retinoic Acid (ATRA) was tested for its action against metastatic lodging of B16F10 melanoma cells in the lung and liver of the C57BL/6 mouse model. Serum, lung and liver were evaluated biochemically for the cancer associated changes. Metastatic cancer development was confirmed by tumor nodule formation and histopathological analysis. RAR-β protein expression was analyzed by immunohistochemistry and histopathology. ATRA treated mice showed a percentage of inhibition on metastatic tumor growth in lung and liver and a corresponding protection against pathological changes in these organs. Cholesterol and γ-Glutamyl Transferase (GGT) levels found in cancer induced mice were reduced in the ATRA treated group. As compared to the normal group, lung tissue from cell line induced cancer control group had less RAR-β protein expression while the ATRA treated group showed enhanced RAR-β protein expression. This indicates that the anti-metastasis effects of ATRA might have shown the induction of RAR-β expression and subsequent molecular signaling pathways to regulate the homeostasis of biochemical changes. This study demonstrated the capability of ATRA to prevent the establishment of metastasis by the melanoma cell line into the lung and liver of experimental mice.

description: We investigate the phenomenon of the diffraction of charged particles by thin material targets using the method of the de Broglie-Bohm quantum trajectories. The particle wave function can be modeled as a sum of two terms $ψ=ψ_{ingoing}+ψ_{outgoing}$. A thin separator exists between the domains of prevalence of the ingoing and outgoing wavefunction terms. The structure of the quantum-mechanical currents in the neighborhood of the separator implies the formation of an array of \emph{quantum vortices}. The flow structure around each vortex displays a characteristic pattern called `nodal point - X point complex'. The X point gives rise to stable and unstable manifolds. We find the scaling laws characterizing a nodal point-X point complex by a local perturbation theory around the nodal point. We then analyze the dynamical role of vortices in the emergence of the diffraction pattern. In particular, we demonstrate the abrupt deflections, along the direction of the unstable manifold, of the quantum trajectories approaching an X-point along its stable manifold. Theoretical results are compared to numerical simulations of quantum trajectories. We finally calculate the {\it times of flight} of particles following quantum trajectories from the source to detectors placed at various scattering angles $θ$, and thereby propose an experimental test of the de Broglie - Bohm formalism.

description: Context: Infrared spectroscopy of primary and secondary eclipse events probes the composition of exoplanet atmospheres and, using space telescopes, has detected H2O, CH4 and CO2 in three hot Jupiters. However, the available data from space telescopes has limited spectral resolution and does not cover the 2.4 - 5.2 micron spectral region. While large ground based telescopes have the potential to obtain molecular-abundance-grade spectra for many exoplanets, realizing this potential requires retrieving the astrophysical signal in the presence of large Earth-atmospheric and instrument systematic errors. Aims: Here we report a wavelet-assisted, selective principal component extraction method for ground based retrieval of the dayside spectrum of HD 189733b from data containing systematic errors. Methods: The method uses singular value decomposition and extracts those critical points of the Rayleigh quotient which correspond to the planet induced signal. The method does not require prior knowledge of the planet spectrum or the physical mechanisms causing systematic errors. Results: The spectrum obtained with our method is in excellent agreement with space based measurements made with HST and Spitzer (Swain et al. 2009b; Charbonneau et al. 2008) and confirms the recent ground based measurements (Swain et al. 2010) including the strong 3.3 micron emission.

description: We studied nanoprecipitates and defects in p-type filled skutterudite CeFe4Sb12 prepared by non-equilibrium melt-spinning plus spark plasma sintering method using transmission electron microscopy. Nanoprecipitates with mostly spherical shapes and different sizes (from several nm to several tens of nm) have been observed. The most typically observed nanoprecipitates are shown to be Sb-rich. Superlattices with a periodicity of about 3.576 nm were induced by the ordering of excessive Sb atoms along the c direction. These nanoprecipitates usually share coherent interfaces with the surrounding matrix and induce anisotropic and strong strain fields in the surrounding matrix. Nanoprecipitates with compositions close to CeSb2 are much larger in size (~ 30 nm) and have orthorhombic structures. Various defects were typically observed on the interfaces between these nanoprecipitates and the matrix. The strain fields induced by these nanoprecipitates are less distinct, possibly because part of the strains has been released by the formation of defects.

The observed phonon energies near Γwere in good agreement with published optical data. It was found that two high-energy modes strongly soften near q=0.25 when the system becomes metallic (x >0.35). There was no softening in the insulating phase, even at x=0.30, very near the metal-insulator transition. This suggests that the phonon softening is linked to the appearance of the Fermi-surface.

description: Sharpless Tis report illustrates the application ofAsymmetric Sharpless Aminohydroxylation (ASAH) in the stereoselective synthesis of vicinal amino alcohols as important intermediates in the total synthesis of complex molecules and natural products with significant biological activities. The ASHA allows the regio- syn-selective synthesis of 1,2-amino alcohols via reaction of alkenes with salts of N-halosulfonamides, -amides and -carbamates employing osmium tetroxide (OsO4) as an efficient catalyst. In this reaction, chirality is induced via the addition of dihydroquinine- and dihydroquinidine as derived chiral ligands.

description: Context: The interaction of plasma motions and magnetic fields is an important mechanism, which drives solar activity in all its facets. For example, photospheric flows are responsible for the advection of magnetic flux, the redistribution of flux during the decay of sunspots, and the built-up of magnetic shear in flaring active regions. Aims: Systematic studies based on G-band data from the Japanese Hinode mission provide the means to gather statistical properties of horizontal flow fields. This facilitates comparative studies of solar features, e.g., G-band bright points, magnetic knots, pores, and sunspots at various stages of evolution and in distinct magnetic environments, thus, enhancing our understanding of the dynamic Sun. Methods: We adapted Local Correlation Tracking (LCT) to measure horizontal flow fields based on G-band images obtained with the Solar Optical Telescope on board Hinode. In total about 200 time-series with a duration between 1-16 h and a cadence between 15-90 s were analyzed. Selecting both a high-cadence (dt = 15 s) and a long-duration (dT = 16 h) time-series enabled us to optimize and validate the LCT input parameters, hence, ensuring a robust, reliable, uniform, and accurate processing of a huge data volume. Results: The LCT algorithm produces best results for G-band images having a cadence of 60-90 s. If the cadence is lower, the velocity of slowly moving features will not be reliably detected. If the cadence is higher, the scene on the Sun will have evolved too much to bear any resemblance with the earlier situation. Consequently, in both instances horizontal proper motions are underestimated. The most reliable and yet detailed flow maps are produced using a Gaussian kernel with a size of 2560 km x 2560 km and a full-width-at-half-maximum (FWHM) of 1200 km (corresponding to the size of a typical granule) as sampling window.

description: Vielfach belegt sind mittlerweile die schwierigen Arbeitsbedingungen in der stationären Altenpflege und die mit ihnen verbundenen teils negativ geprägten Erfahrungen der Mitarbeiter vor dem Hintergrund des Spannungsfeldes zwischen der Gewährleistung einer möglichst hohen Pflegequalität (der idealistische Anspruch des Sollens) und den tatsächlichen Rahmenbedingungen (das reale Sein). Im Rahmen der Dissertation wird durch die Definition eines moralischen Standards in Anlehnung an die bereits bestehenden Expertenstandards ein neuer Ansatz für den Umgang mit diesem Widerspruch entwickelt. Dieser basiert auf allgemeinen Annahmen für einen ethisch adäquaten Pflege- und Betreuungsprozess in der stationären Altenpflege und kann an die Rahmenbedingungen der jeweiligen Einrichtung (erste Ebene der Individualisierung) beziehungsweise an die jeweilige Situation des Heimbewohners (zweite Ebene der Individualisierung) angepasst werden. Damit bietet er den Mitarbeitern ein Instrument nicht nur für Grenzfälle (u.a. sterbende oder demente Heimbewohner), sondern auch für die ganz alltäglichen Entscheidungen im Pflege- und Betreuungsprozess. Zur Definition des moralischen Standards wurden Kenntnisse unterschiedlicher Disziplinen (Anthropologie, Gerontologie, Pflegewissenschaften, Philosophie des Geistes, Metaethik, deskriptive und präskriptive Ethik) mittels empirischer Ethik auf innovative Weise so miteinander kombiniert, dass für die stationäre Altenpflege ein neuartiges potentielles Qualitätsinstrument geschaffen werden konnte. Dieses wird in Anlehnung an das populäre Georgetown-Mantra von Tom L. Beauchamp und James F. Childress gebildet durch fünf Grundprinzipien medizinisch-pflegerischer Intervention (Vertrauen, Respekt vor der Würde, Respekt vor Selbstbestimmung und Autonomie, Leidreduktion, Gerechtigkeit), die anhand anthropologischer (Altern und Mortalität, Sichtbarkeit von Körper und Leid, Bewusstsein und Selbstbewusstsein, Bedürfnisse) und geroanthropologischer (Alter und Hochaltrigkeit, Multimorbidität, Defizite und Kompetenzverluste, Schrumpfung des sozialen Netzwerkes, Nähe zum Tod) Konstanten erklärt und gerechtfertigt werden.
Cognitive ecology & visual poetry : toward a multimodal cognitive poetics
Creators: name: Borkent, Michael
Publisher: name: University of British Columbia
Year: 2015

description: In this dissertation I offer a new approach to North American visual poetry. I develop an eco-cognitive analysis of visual poetic features and bring them into critical dialogue with other literary genres. I focus primarily on the Canadian tradition and reception of visual poetry, using it as a helpful microcosm for discussions of poetic influence and critical engagement, while also bringing it into dialogue with experimental and lyrical transnational Anglophone poetry and poetics. I propose an interdisciplinary methodology that addresses visual poetry as a hybrid of verbal, visual, and tactile modes of communication. I discuss visual poetry from the perspective of conceptual mechanisms that produce specific interpretive possibilities, thereby offering a more robust account of how visual poems specifically interact with the materiality of print culture. I begin by defining multimodal literature and visual poetry and outlining a multimodal approach to media that bridges traditional poetic and hermeneutic approaches. I propose a model of cognitive ecology as a framework that meets the needs of visual poetic criticism. In particular, I rely on research into perception, mental simulation, and conceptual integration to show how communicative modalities are transformed to yield synthetic multimodal understandings of hybrid texts. Furthermore, I consider common cognitive biases to expose the underlying fallacious assumptions in several poetic, critical, and popular approaches to visual poetry in Canada and abroad. I then show how my eco-cognitive framework offers a more productive understanding of the interactions between modalities. I offer critical tools which view the poems as multimodal anchors for conceptualization, thereby distinguishing between multimodal textuality and the readerly experience of it. Finally, I develop a theory of cognitive improvisation which addresses how even illegible or abstract cues in visual poetry can prompt meaningful interpretations. I argue that all experiences of texts involve some level of cognitive improvisation, but that visual poetry foregrounds this aspect of everyday creativity. Finally, I show how this multimodal cognitive poetics extends naturally to other forms of multimodal literature, especially comics and graphic novels.

description: A graph is a data structure composed of dots (i.e. vertices) and lines (i.e. edges). The dots and lines of a graph can be organized into intricate arrangements. The ability for a graph to denote objects and their relationships to one another allow for a surprisingly large number of things to be modeled as a graph. From the dependencies that link software packages to the wood beams that provide the framing to a house, most anything has a corresponding graph representation. However, just because it is possible to represent something as a graph does not necessarily mean that its graph representation will be useful. If a modeler can leverage the plethora of tools and algorithms that store and process graphs, then such a mapping is worthwhile. This article explores the world of graphs in computing and exposes situations in which graphical models are beneficial.

title: Object Documentary: The Ethics of the Documentary Encounter Reframed
Creators: name: Norouzi, Minou
Publisher: name: Goldsmiths, University of London
Year: 2018

description: This practice-based research explores the objectification of the real in the context of interdisciplinary documentary practices. The exploration is undertaken through historical theoretical research, through interviews, and through my practice as a filmmaker and film curator. The research outcome comprises a written thesis, a film, and two curatorial projects. The central concern is the objectification of the real. By this I mean, perceiving the ‘real’ as a material resource. When artists use the real as material, does it always amount to a negative form of objectification? I explore objectification as a mode of resistance, as a way of destabilising the documentary method itself, and argue for objectification as a critical aesthetic method. 

The research context circles around the so-called documentary turn where critical debates on ‘truth’, power, and ethics have resurfaced since the mid-1990s. My approach throughout is to move away from dualist subject/object relational thinking. Instead, the research configures a theoretical field of thought and puts into practice a method that considers both the aesthetic potential and the ethical challenges of an object-to-object relation. Whilst the research derives some concepts from an intersection of materialist philosophies, its primary drive is to reframe documentary ethics. I position documentary films and their constituents as objects in order to examine the ethics of this approach. The analysis presented aims to show that the critical method of the works explored, in part, consists of soliciting an ethical response through the production of discomfort. I argue objectification is central to this method. By reframing the relationship between films, filmmakers, and film viewers, I come to define the role of documentary making and viewing, as creating spaces for self-interrogation through a shared modality I call omnidirectional responsibility. This responsibility is considered through an inter-objective sensibility. That is, the physical engagement with the material world as material.

description: We introduce a toy model implementing the proposal of using a custodial symmetry to protect the Zbb coupling from large corrections. This "doublet-extended standard model" adds a weak doublet of fermions (including a heavy partner of the top quark) to the particle content of the standard model in order to implement an O(4) x U(1)_X = SU(2)_L x SU(2)_R x P_{LR} x U(1)_X symmetry that protects the Zbb coupling. This symmetry is softly broken to the gauged SU(2)_L x U(1)_Y electroweak symmetry by a Dirac mass M for the new doublet; adjusting the value of M allows us to explore the range of possibilities between the O(4)-symmetric (M to 0) and standard-model-like (M to infinity) limits.

title: Canadian and US mass media representation of Iranian women and their activities in social movements
Creators: name: Nezhadhossein, Elahe
Publisher: name: Memorial University of Newfoundland

description: Media can display a stereotypical image of women to represent, produce, or reinforce an inequality system. In Western mass media, images of Iranian women as women of a Muslim, Middle Eastern country may not provide a comprehensive view of these women. To understand the dominant discourses in the US and Canada’s mass media, my research asks: How are Iranian women represented in US and Canadian media, and have there been any changes in this representation during the years since the Islamic Revolution of 1979 and, more specifically, after 2001? Have women’s activities in social movements in Iran, specifically since 2009, had any effects on their representations in Canadian and US media? Through a critical discourse analysis of four widely circulated national newspapers in Canada and the US, and using theories of hegemony and counter-hegemony, social movements and power of networks, and intersectionality, my research shows that women in Iran have gained attention from the Canadian and US mass media by means of their participation in street protests. The results show that media images of women and their activities since 2009 include more positive representations and are different, in the main, from the older images of women during the years immediately after the Islamic Revolution or stereotypical images of Middle Eastern women as victims of an oppressive Islamic system. In general, when women’s activities and their resistance take forms that are familiar to US and Canadian mass media, they receive greater visibility. The results also show that overall representations of Iranian women in the media vary more so with the orientation of newspapers than media geographies. However, in some respects, such as the images in which the hijab is featured, the dominant discourse has not changed; the hijab is represented as oppressive and negative in both time-periods. The focus of the newspapers remain on the hijab law in both time-periods, and women’s clothes are represented as mainly oppressive.

description: The asymptotic behavior of the integrated density of states for a randomly perturbed lattice at the infimum of the spectrum is investigated. The leading term is determined when the decay of the single site potential is slow. The leading term depends only on the classical effect from the scalar potential. To the contrary, the quantum effect appears when the decay of the single site potential is fast. The corresponding leading term is estimated and the leading order is determined. In the multidimensional cases, the leading order varies in different ways from the known results in the Poisson case. The same problem is considered for the negative potential. These estimates are applied to investigate the long time asymptotics of Wiener integrals associated with the random potentials.

Stokes' Cradle: Newton's Cradle with Liquid Coating

description: Flows involving liquid-coated grains are ubiquitous in nature (pollen capture, avalanches) and industry (air filtration, smoke-particle agglomeration, pharmaceutical mixing). In this work, three-body collisions between liquid-coated spheres are investigated experimentally using a "Stokes' cradle", which resembles the popular desktop toy known as the Newton's cradle. Surprisingly, previous work indicates that every possible outcome was observed in the wetted system except the traditional Newton's cradle (NC) outcome. Here, we are able to experimentally achieve NC via guidance from a first-principles model, which revealed that controlling the volume of the liquid bridge connecting the two target particles is the key parameter in attaining the NC outcome. By independently decreasing the volume of the liquid bridge, we not only achieved NC but also uncovered several new findings. For example, in contrast to previous work on two-body collisions, three-body experiments provide direct evidence that the fluid resistance upon rebound cannot be completely neglected due to presumed cavitation; this resistance also plays a role in two-body systems yet cannot be isolated experimentally in such systems. The herein micro-level description provides an essential foundation for macro-level descriptions of wetted granular flows.

Continuous symmetry reduction and return maps for high-dimensional flows

description: We present two continuous symmetry reduction methods for reducing high-dimensional dissipative flows to local return maps. In the Hilbert polynomial basis approach, the equivariant dynamics is rewritten in terms of invariant coordinates. In the method of moving frames (or method of slices) the state space is sliced locally in such a way that each group orbit of symmetry-equivalent points is represented by a single point. In either approach, numerical computations can be performed in the original state-space representation, and the solutions are then projected onto the symmetry-reduced state space. The two methods are illustrated by reduction of the complex Lorenz system, a 5-dimensional dissipative flow with rotational symmetry. While the Hilbert polynomial basis approach appears unfeasible for high-dimensional flows, symmetry reduction by the method of moving frames offers hope.

description: The signature of defects in the optical spectra of hexagonal boron nitride (BN) is investigated using many body perturbation theory. A single BN-sheet serves as a model for different layered BN- nanostructures and crystals. In the sheet we embed prototypical defects such as a substitutional impurity, isolated Boron and Nitrogen vacancies, and the di-vacancy. Transitions between the deep defect levels and extended states produce characteristic excitation bands that should be responsible for the emission band around 4 eV, observed in luminescence experiments. In addition, defect bound excitons occur that are consistently treated in our ab initio approach along with the "free" exciton. For defects in strong concentration, the co-existence of both bound and free excitons adds sub-structure to the main exciton peak and provides an explanation for the corresponding feature in cathodo and photo-luminescence spectra.

description: The occurrence of disasters has a significant influence on hospitals. The accessibility of the hospital emergency information system may be compromised due to an inconsistent network connection. In order to address this requirement, it is necessary to develop a website system that is capable of functioning in situations where the network connection is limited or unavailable, sometimes referred to as offline functionality. Progressive Web Apps (PWA) is the theory of creating web-based applications that are user-friendly, even in situations where the Internet connection is limited or there is no Internet connection at all by utilizing Service Workers. This offline-first hospital system solution is achieved by combining Service Workers technology with React JavaScript for frontend development and cloud Firestore for backend data storage. This research conducts a comparative analysis between online programs versus programs that utilize Service Workers. Additionally, this device incorporates a Raspberry Pi server to support the edge computing emergency response architecture. The findings indicate that web Service Workers exhibit a notably faster average access time and average browser processing time compared to their counterparts. The throughput test indicates that the incorporation of integrated web Service Workers results in a greater volume of requests generated within a certain time frame compared to the scenario in which Service Workers are not employed. The hospital emergency information system has proven its ability to function reliably and effectively utilizing diverse technologies, improving disaster resilience, and facilitating access to Progressive Web Apps medical records.
