description: Blind and universal image denoising consists of using a unique model that denoises images with any level of noise. It is especially practical as noise levels do not need to be known when the model is developed or at test time. We propose a theoretically-grounded blind and universal deep learning image denoiser for additive Gaussian noise removal. Our network is based on an optimal denoising solution, which we call fusion denoising. It is derived theoretically with a Gaussian image prior assumption. Synthetic experiments show our network's generalization strength to unseen additive noise levels. We also adapt the fusion denoising network architecture for image denoising on real images. Our approach improves real-world grayscale additive image denoising PSNR results for training noise levels and further on noise levels not seen during training. It also improves state-of-the-art color image denoising performance on every single noise level, by an average of 0.1dB, whether trained on or not.

Generalized Cardassian Expansion: Models in Which the Universe is Flat, Matter Dominated, and Accelerating

description: The Cardassian universe is a proposed modification to the Friedmann Robertson Walker (FRW) equation in which the universe is flat, matter dominated, and accelerating. Here we generalize the original Cardassian proposal to include additional variants on the FRW equation. Specific examples are presented. In the ordinary FRW equation, the right hand side is a linear function of the energy density, $H^2 \sim ρ$. Here, instead, the right hand side of the FRW equation is a different function of the energy density, $H^2 \sim g(ρ)$. This function returns to ordinary FRW at early times, but modifies the expansion at a late epoch of the universe. The only ingredients in this universe are matter and radiation: in particular, there is {\it no} vacuum contribution. Currently the modification of the FRW equation is such that the universe accelerates. The universe can be flat and yet consist of only matter and radiation, and still be compatible with observations. The energy density required to close the universe is much smaller than in a standard cosmology, so that matter can be sufficient to provide a flat geometry. The modifications may arise, e.g., as a consequence of our observable universe living as a 3-dimensional brane in a higher dimensional universe. The Cardassian model survives several observational tests, including the cosmic background radiation, the age of the universe, the cluster baryon fraction, and structure formation. As will be shown in future work, the predictions for observational tests of the generalized Cardassian models can be very different from generic quintessence models, whether the equation of state is constant or time dependent.

description: This dissertation analyzes the intellectual and political contributions of choreographer Katherine Dunham (1909-2006). As an African American woman, Dunham broke several barriers of race and gender, first as an anthropologist conducting ethnographic fieldwork in the Caribbean in the 1930s, and second as the artistic director of a major dance company that toured the United States, Latin America, Europe, Asia, and Australia from the 1930s through the 1960s. She also wrote several scholarly books and articles, opened multiple schools, and served on the boards of numerous arts organizations. Although Dunham's contributions to anthropology and dance are vitally important, "Choreographing a New World" emphasizes her political engagement. Through actions both onstage and off, she helped strengthen the transnational ties of black social movements from the New Negro Movement to the Black Power Movement. In particular, the dissertation contends that Dunham made dance one of the primary forces in the creation and perpetuation of the African diaspora. She herself attempted to live diaspora by forging personal connections across racial, linguistic, national, class, and cultural borders.
      In order to shift the focus to Dunham's intellectual and political engagement, "Choreographing a New World" turns to previously untapped archival sources. This dissertation is the first scholarly work on Dunham to examine archives from the U.S. State Department, Office of Economic Opportunity, Bernard Berenson Papers, Rockefeller Foundation Records, Langston Hughes Papers, and Rosenwald Foundation Papers, among other archives. It combines insights from these archives with choreographic analysis, interviews with Dunham's former dancers and students, and embodied participant-observation research at the annual International Katherine Dunham Technique Seminars from 2010 to 2013. Overall, "Choreographing a New World" not only provides a new perspective on Dunham, but also raises important questions about dance as an intellectual and political activity, especially within an African diasporic context.

description: Surfaces in i-Al68Pd23Mn9 as observed with STM and LEED experiments show atomic terraces in a Fibonacci spacing. We analyze them in a bulk tiling model due to Elser which incorporates many experimental data. The model has dodecahedral Bergman clusters within an icosahedral tiling T^*(2F) and is projected from the 6D face-centered hypercubic lattice. We derive the occurrence and Fibonacci spacing of atomic planes perpendicular to any 5fold axis, compute the variation of planar atomic densities, and determine the (auto-) correlation functions. Upon interpreting the planes as terraces at the surface we find quantitative agreement with the STM experiments.

description: Single-shot time-of-flight spectra for Coulomb explosion of N2 and I2 molecules have been recorded at the Free Electron LASer in Hamburg (FLASH) and have been analysed using a partial covariance mapping technique. The partial covariance analysis unravels a detailed picture of all significant Coulomb explosion pathways, extending up to the N4+–N5+ channel for nitrogen and up to the I8+–I9+ channel for iodine. The observation of the latter channel is unexpected if only sequential ionization processes from the ground state ions are considered. The maximum kinetic energy release extracted from the covariance maps for each dissociation channel shows that Coulomb explosion of nitrogen molecules proceeds much faster than that of the iodine. The N2 ionization dynamics is modelled using classical trajectory simulations in good agreement with the outcome of the experiments. The results suggest that covariance mapping of the Coulomb explosion can be used to measure the intensity and pulse duration of free-electron lasers.

description: Taking advantage of the two-parameter central extension of the planar Galilei group, we construct a non relativistic particle model in the plane. Owing to the extra structure, the coordinates do not commute. Our model can be viewed as the non-relativistic counterpart of the relativistic anyon considered before by Jackiw and Nair. For a particle moving in a magnetic field perpendicular to the plane, the two parameters combine with the magnetic field to provide an effective mass. For vanishing effective mass the phase space admits a two-dimensional reduction, which represents the condensation to collective ``Hall'' motions and justifies the rule called ``Peierls substitution''. Quantization yields the wave functions proposed by Laughlin to describe the Fractional Quantum Hall Effect.

description: This study develops a model for students and graduates of Soft Skills, Hard Skills, and Competitiveness (SHC) and seeks user validation after the development process. The development process uses the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model. A quantitative survey using questionnaires and descriptive quantitative analysis was applied in obtaining user validation as the study objective. The development results validated the students' SHC Development model, which has 3 main phases, including Input, Process and Output. The Input phase comprises course content, SHC component, and strategy of students’ center approach. The Process phase consists of blended course design, instruction and students' engagement, and evaluation. The Output phase comprises soft and hard skills achievement, as well as students’ competitiveness level. Users perceived the model’s phases and components as wholly acceptable, appropriate, and applicable for implementation through curriculum, teaching, and learning at the university. This study contributes to graduate preparation for employability skills in the challenging and complex working environment in revolution industry 4.0.

I discuss the see-saw mechanism, and show how it may be applied in a very natural way to give a neutrino mass hierarchy with large atmospheric and solar angles by assuming single right-handed neutrino dominance. A theoretical framework for understanding quark and lepton (including neutrino) masses and mixing angles based on SUSY, GUTs and Family symmetry is then described, and sample models which involve single right-handed neutrino dominance are discussed.

description: Background Midwives are frequently exposed to traumatic birth events which may place them at risk of developing posttraumatic stress (PTS) symptoms. Posttraumatic stress can reduce empathic and cognitive abilities and increase perceptions of risk and danger. PTSD research and theory have identified personal, trauma event-related and work environment related variables as risk factors for PTSD. It is not known whether these factors also apply among midwives. Aims 1. To identify prevalence of posttraumatic stress among Australian midwives. 2. To identify risk factors for posttraumatic stress and use a socioecological model to explain posttraumatic stress in midwives. Methods A national internet survey of midwives who are members of the Australian College of Midwives was conducted. Trauma symptoms were assessed with the PTSD Symptom Scale Self-Report version (PSS-SR). Probable PTSD was assessed as meeting DSM IV PTSD diagnostic criteria B, C and D (a score of at least ‘one’ on the four-point frequency scale for a minimum of one intrusion, three avoidance and two arousal symptoms) and a total PSS-SR score ≥14. The Traumatic Experiences in Perinatal Care List (TEPCL) assessed which types of birth events were perceived as traumatic by midwives. The Sensitivity in Perinatal Care Scale (SPCS) was developed to assess sensitivity in perinatal caregiving. Other measures included the Interpersonal Reactivity Index (IRI) to assess empathy and the Job Content Questionnaire (JCQ) to assess job demands and job control.

Based on \cite{Perenon:2016blf}, we review the diagnostic of these theories on the correlation of the large-scale structure phenomenological functions: the effective Newton constant, the light deflection parameter and the growth function of matter perturbations. We take this opportunity to discuss the evolution of the bounds the propagation speed of gravitational waves has undergone and use the most restrictive one to update the diagnostic.

The curvaton as a Bose-Einstein condensate of chiral pseudo Nambu-Goldstone bosons

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

description: Explaining cosmic inflation by the effective dynamics of an $SU(N_C)$ pure gauge theory of scale $\La\sim 10^{-6} M_p$ is lacking an explanation of the (Gaussian) spatial curvature perturbations needed to seed the formation of large-scale structure after inflation. In this work it is demonstrated how fundamentally charged fermions of mass $m_F\sim 10^{-12} \La$, whose approximate chiral symmetry is spontaneously broken during inflation, can cure this shortcoming. The associated gas of weakly interacting pseudo Nambu-Goldstone bosons (PNGB) undergoes Bose-Einstein (BE) condensation well before the end of inflation. This causes the occurence of condensed light scalar fields effectively acting as a curvaton. Fermions may also be charged under a gauge group $G$ with a weak coupling $g$. Since fermions charged under $SU(N_C)$ are confined after inflation the decay of Nambu-Goldstone bosons, which reside in the condensates and in the PNGB radiation generated at reheating, is mainly into fermions {\sl solely} charged under $G$. The associated decay rate $Γ$ is estimated using PCAC and large $N_C$ counting. PNGB decay takes place during radiation domination after cosmological scales have entered the horizon. Neglecting the effects of the spontaneous breaking of G induced by the BE condensation, it is demonstrated that the observed spectrum of spatial curvature perturbations $P^{1/2}_ξ\sim 5\times 10^{-5}$ is compatible with $g\sim 10^{-3}$, a ratio $r_{\tiny{dec}}\sim 10^{-4}$ of curvaton to radiation energy at PNGB decay, and a curvaton effective equation of state $p_{\tiny{curv}}=-0.9 ρ_{\tiny{curv}}$.

Multitask Deep Learning with Spectral Knowledge for Hyperspectral Image Classification

Year: 2019
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: In this letter, we propose a multitask deep learning method for classification of multiple hyperspectral data in a single training. Deep learning models have achieved promising results on hyperspectral image classification, but their performance highly rely on sufficient labeled samples, which are scarce on hyperspectral images. However, samples from multiple data sets might be sufficient to train one deep learning model, thereby improving its performance. To do so, we trained an identical feature extractor for all data, and the extracted features were fed into corresponding Softmax classifiers. Spectral knowledge was introduced to ensure that the shared features were similar across domains. Four hyperspectral data sets were used in the experiments. We achieved higher classification accuracies on three data sets (Pavia University, Pavia Center, and Indian Pines) and competitive results on the Salinas Valley data compared with the baseline. Spectral knowledge was useful to prevent the deep network from overfitting when the data shared similar spectral response. The proposed method tested on two deep CNNs successfully shows its ability to utilize samples from multiple data sets and enhance networks' performance.

description: This dissertation examines Cicero’s contribution to the rise of astronomy and astrology in the literary and cultural milieu of the late Republic and early Empire. Chapter One, “Rome’s Star Poet,” examines how Cicero conceives of world building through words to connect Rome to the stars with the Latin language. Through a close study of the Aratea, I consider how Cicero’s pioneering of Latin astronomical language influenced other writers, especially his contemporaries Lucretius and Catullus. In Chapter Two, “The Stars and the Statesman,” I examine Cicero’s attitudes towards politics. By analyzing Scipio’s Dream and astronomy in De re publica, I show how Cicero uses cosmic models to yoke Rome to the stars. To understand the astral dimensions of Cicero’s philosophy, in Chapter Three, “Signs and Stars, Words and Worlds,” I provide a close reading of Cicero’s poetic quotations in context in the De natura deorum and De divinatione to show how Cicero puts the Aratean cosmos to the test in Academic fashion. Ultimately, I argue that Cicero profoundly shaped the Roman view of the stars and cemented the link between cosmos and empire.

description: Ellipticity of boundary value problems is characterized in terms of the Calderon projector. The presence of topological obstructions for the chiral Dirac operator under local boundary conditions in even dimension is discussed. Functional determinants for Dirac operators on manifolds with boundary are considered. The functional determinant for a Dirac operator on a bidimensional disk, in the presence of an Abelian gauge field and subject to global boundary conditions of the type introduced by Atiyah-Patodi-Singer, is evaluated. The relationship with the index theorem is also commented.

Quand le biotope est précisé, il s’agit toujours de savane (Ziéla, Kéoulenta); le milieu n’est pas indiqué pour Yalanzou, Yéalé, Séringbara et Pierré Richaud (captures de 1942), mais dans le cas des deux dernières localités au moins, la savane doit être également le milieu de vie. Des adultes ont été pris en février, juin, octobre et décembre, des jeunes en février, mars, juillet et d’octobre à décembre, ce qui semble indiquer une reproduction continue, conformément à ce que l’on sait par ailleurs sur cette espèce.

description: I propose a method to decompose changes in income inequality into the contributions of policy changes, wage rate changes, and population changes while considering labor supply reactions. Using data from the Socio-Economic Panel (SOEP), I apply this method to decompose the increase in income inequality in Germany from 2002 to 2011, a period that saw tax reductions and a controversial overhaul of the transfer system. The simulations show that tax and transfer reforms have had an inequality reducing effect as measured by the Mean Log Deviation and the Gini coefficient. For the Gini, these effects are offset by labor supply reactions. In contrast, policy changes explain part of the increase in the ratio between the 90th and the 50th income percentile. Changes in wage rates have led to a decrease in income inequality. Thus, the increase in inequality was mainly due to changes in the population.
Church Historians and Maronite Communal Consciousness: Agency and Creativity in Writing the History of Mount Lebanon

description: The intent of this dissertation is to trace the genealogy of Maronite identity through an examination of the development of the historical tradition that shaped its contemporary manifestation. It examines how the current identity of the Lebanese Maronite community was formed and how its content is claimed by those interpolated by it as a stable and fixed essence, and what the claims of the contemporary nationalists regarding its formation would be. What this study aims to reveal, is how early Maronite historiography's plea for inclusion, as a part of Catholic orthodoxy, was transformed and recast in subsequent centuries into a demand for exclusion and exclusivity. The metahistorical task of Maronite ecclesiastical historiography, the claim of perpetual orthodoxy was recast through emplotment in different narratives that perform oppositional tasks relevant to each era and each political project. Those include an exclusivist and exclusionary political history with the nineteenth century rise of sectarian politics, as well as a nationalist narrative in the twentieth century that attempted to preserve Maronite privilege and political ascendency. This study brings evidence to bear on a particular aspect of history writing in Lebanon by presenting a reassessment and re-examination of an existing historiographical debate. It will demonstrate how history writing is one of the main instruments in generating and perpetuating nationalist myths and ideologies and that historians are central agents of nationality.

description: Four dimensional reflexive polyhedra encode the data for smooth Calabi-Yau threefolds that are hypersurfaces in toric varieties, and have important applications both in perturbative and in non-perturbative string theory. We describe how we obtained all 473,800,776 reflexive polyhedra that exist in four dimensions and the 30,108 distinct pairs of Hodge numbers of the resulting Calabi-Yau manifolds. As a by-product we show that all these spaces (and hence the corresponding string vacua) are connected via a chain of singular transitions.

description: We enumerate certain geometric equivalence classes of subgraphs induced by Hamiltonian paths and cycles in complete graphs. Said classes are orbits under the action of certain direct products of dihedral and cyclic groups on sets of strings representing subgraphs. These orbits are enumerated using Burnside's lemma. The technique used also provides an alternative proof of the formulae found by S. W. Golomb and L. R. Welch which give the number of distinct $n$-gons on fixed, regularly spaced vertices up to rotation and optionally reflection.

Numerical study of the transverse localization of waves in one-dimensional lattices with randomly distributed gain and loss: Effect of disorder correlations

description: We study numerically the effects of short- and long-range correlations on the localization properties of the eigenstates in a one-dimensional disordered lattice characterized by a random non-Hermitian Hamiltonian, where the imaginary part of the on-site potential is random. We calculate participation number versus strengths of disorder and correlation. In the short-ranged case and when the correlation length is sufficiently small, we find that there exists a critical value of the disorder strength, below which enhancement and above which suppression of localization occurs as the correlation length increases. In the region where the correlation length is larger, localization is suppressed in all cases. A similar behavior is obtained for long-range correlations as the disorder strength and the correlation exponent are varied. Unlike in the case of a long-range correlated real random potential, no signature of the localization transition is found in a long-range correlated imaginary random potential. In the region where localization is enhanced in the presence of long-range correlations, we find that the enhancement occurs in the whole energy band, but is strongest near the band center. In addition, we find that the anomalous localization enhancement effect occurs near the band center in the long-range correlated case.

title: Destination Brand Governance: An Exploration of Destination Management Organisations’ and Operators’ Perspectives.

description: This thesis explores Destination Management Organisations’ (DMOs) and operators’ role in destination branding. The thesis draws upon a resource-based view to explore how the combination of a destination’s key resources and capabilities (i.e. destination brand) create valuable destination experiences that are aligned to consumer needs and wants. In doing so, through a multi-stakeholder exploration of branding practices, this thesis builds on existing destination branding literature. As the broker of the destination’s resources, the DMO must balance the relationships with operators to establish a consistent destination experience through brand governance. Yet, destination brand governance is complex due to the heterogeneity of the organisations involved developing and delivering the brand. As such, balancing the relationships within the destination to establish brand buy-in is a challenge for DMOs. This thesis defines brand buy-in as the operators’ willingness to engage positively with the destination brand. The process requires the operators and DMOs to contribute resources together to achieve a consistent brand experience. Failure to do so weakens brand experience and negatively influences consumer loyalty. It is therefore vital that DMOs understand the dominant logic influencing operators’ destination branding goals to stimulate brand buy-in. The absence of empirical research exploring destination brands from an operator perspective and, in particular, ways to promote their buy-in prompt the need for this research. In doing so, ways for DMOs to balance operator relationships through governance mechanisms are revealed

Generalized Fock Spaces, New Forms of Quantum Statistics and their Algebras

Year: 1996
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We formulate a theory of generalized Fock spaces which underlies the different forms of quantum statistics such as ``infinite'', Bose-Einstein and Fermi-Dirac statistics. Single-indexed systems as well as multi-indexed systems that cannot be mapped into single-indexed systems are studied. Our theory is based on a three-tiered structure consisting of Fock space, statistics and algebra. This general formalism not only unifies the various forms of statistics and algebras, but also allows us to construct many new forms of quantum statistics as well as many algebras of creation and destruction operators. Some of these are : new algebras for infinite statistics, q-statistics and its many avatars, a consistent algebra for fractional statistics, null statistics or statistics of frozen order, ``doubly-infinite'' statistics, many representations of orthostatistics, Hubbard statistics and its variations.

description: Magnon propagation length in a ferrimagnetic insulator yttrium iron garnet (YIG) has been investigated by measuring and analyzing the YIG-thickness t_YIG dependence of the spin Peltier effect (SPE) in a Pt/YIG junction system. By means of the lock-in thermography technique, we measured the spatial distribution of the SPE-induced temperature modulation in the Pt/YIG system with the t_YIG gradation, allowing us to obtain the accurate t_YIG dependence of SPE with high t_YIG resolution. Based on the t_YIG dependence of SPE, we verified the applicability of several phenomenological models to estimate the magnon diffusion length in YIG.
