description: We use rotation stereoscopy to estimate the height of a steady-state solar feature relative to the photosphere, based on its apparent motion in the image plane recorded over several days of observation. The stereoscopy algorithm is adapted to work with either one- or two-dimensional data (i.e. from images or from observations that record the projected position of the source along an arbitrary axis). The accuracy of the algorithm is tested on simulated data, and then the algorithm is used to estimate the coronal radio source heights associated with the active region NOAA 10956, based on multifrequency imaging data over 7 days from the Siberian Solar Radio Telescope near 5.7 GHz, the Nobeyama Radio Heliograph at 17 GHz, as well as one-dimensional scans at multiple frequencies spanning the 5.98--15.95 GHz frequency range from the RATAN-600 instrument. The gyroresonance emission mechanism, which is sensitive to the coronal magnetic field strength, is applied to convert the estimated radio source heights at various frequencies, h(f), to information about magnetic field vs. height B(h), and the results are compared to a magnetic field extrapolation derived from photospheric magnetic field observations obtained by Hinode and MDI. We found that the gyroresonant emission comes from the heights exceeding location of the third gyrolayer irrespectively on the magnetic extrapolation method; implications of this finding for the coronal magnetography and coronal plasma physics are discussed.

description: We consider a continuum model describing the dynamic behavior of nematic liquid crystal elastomers (LCEs) and implement a numerical scheme to solve the governing equations. In the model, the Helmholtz free energy and Rayleigh dissipation are used, within a Lagrangian framework, to obtain the equations of motion. The free energy consists of both elastic and liquid crystalline contributions, each of which is a function of the material displacement and the orientational order parameter. The model gives dynamics for the material displacement, the scalar order parameter and the nematic director, the latter two of which correspond to the orientational order parameter tensor. Our simulations are carried out by solving the governing equations using an implicit-explicit scheme and the Chebyshev polynomial method. The simulations show that the model can successfully capture the shape changing dynamics of LCEs that have been observed in experiments, and also track the evolution of the order parameter tensor.

description: We briefly study the dynamics at classical level of the Carrollian limit, with vanishing speed of light and no possible propagation of signals, for a simply effective action in a flat space with a open string tachyon as scalar field. The canonical analysis of the theory indicates that the equation of motion is of Dirac type contrary to non-relativistic case where the equation is of Schrodinger type. The ultimate intention is to analize the latter case with electromagnetic fluxes finding that in this case the open string tachyon cannot be interpreted as time.

description: The defect of a function $f:M\rightarrow \mathbb{R}$ is defined as the difference between the measure of the positive and negative regions. In this paper, we begin the analysis of the distribution of defect of random Gaussian spherical harmonics. By an easy argument, the defect is non-trivial only for even degree and the expected value always vanishes. Our principal result is obtaining the asymptotic shape of the defect variance, in the high frequency limit. As other geometric functionals of random eigenfunctions, the defect may be used as a tool to probe the statistical properties of spherical random fields, a topic of great interest for modern Cosmological data analysis.

description: In this paper we study photon pairs generated in a nonlinear cavity, composed of a nonlinear crystal surrounded by mirrors, by the process of spontaneous parametric downconversion. We analyze two different regimes: singly-resonant cavities where the signal and idler modes are resonant, and doubly-resonant cavities where the pump mode is also resonant. We present analytic expressions for the joint spectral amplitude in these two cases, and study the reduction in emission bandwidth as the cavity coefficient finesse is increased. We also study the enhancement of the source brightness resulting from the presence of the cavity.

FE-Modellierung von Holzschraubenverbindungen in Vollholz und Furnierschichtholz unter axialer Beanspruchung
Creators: name: Bertram, Christian

description: Die vorliegende Arbeit beschäftigt sich vorwiegend mit der axialen Steifigkeit von selbstbohrenden Holzschrauben. Hierzu wurde ein numerisches Modell entwickelt, mit welchem sich derartige Verbindungen für nahezu beliebige Geometrien und Einbindetiefen der Schrauben untersuchen lassen. Das Modell liefert ein vertieftes Verständnis der Spannungszustände sowohl im Holz als auch in der Schraube. Da ein Abgleich der Ergebnisse bestehender Versuche nur eine geringe Übereinstimmung mit den Simulationen ergab, wurden weitere Versuche geplant und durchgeführt. Neben klassischen Ausziehversuchen wurden auch Verbindungen geprüft, bei denen die Schrauben zuvor eingeklebt wurden. Insbesondere für Hölzer aus Buchenschnittholz und Buchenfurnierschichtholz war eine gute Übereinstimmung der Ergebnisse aus Versuchen und Simulationen zu erkennen. Dabei wiesen die eingeklebten Schrauben durchweg die höchste axiale Steifigkeit auf.

description: We present the first abundances analysis based on high-resolution infrared (IR) echelle spectra of NGC 6569 and NGC 6624, two moderately reddened globular clusters located in the outer bulge of the Galaxy. We find [Fe/H]=-0.79$\pm$0.02 dex and [Fe/H]=-0.69$\pm$0.02 dex for NGC 6569 and NGC 6624, respectively and an average $α$-elements enhancement of $\approx$+0.43$\pm$0.02 dex and +0.39$\pm$0.02 dex, consistent with previous measurements on other metal-rich Bulge clusters. We measure accurate radial velocities of $\rm =-47\pm 4 km s^{-1}$ and $\rm =+51\pm 3 km s^{-1}$ and velocity dispersions of $\rm \approx 8 km s^{-1}$ and $\rm \approx6 km s^{-1}$ for NGC 6569 and NGC 6624, respectively. Finally, we find very low $^{12}C/^{13}C$ isotopics ratio ($\leq$7 in NGC 6624 and $\approx$5 in NGC 6569), confirming the presence extra-mixing mechanisms during the red giant branch evolution phase.

Distributed skip list in fine-grain message passing interface : implementation and analysis of a dictionary data structure that supports range queries
Creators: name: Alam, Sarwar
Publisher: name: University of British Columbia
Year: 2014

description: With scalability in mind, we have implemented a pure message-passing distributed data structure ideal for range queries. The structure is a distributed skip list that takes full advantage of Fine-Grain MPI to execute on a variety of scales ranging from a single multicore to multiple machines across clusters. The skip list data structure provides parallel implementation of range queries. Our implementation architecture is based on several services layered on top of each other that simplifies the effort required in building distributed code. Unlike concurrent data structures the distributed skip list operations are deterministic and atomic. The layered service architecture of our implementation exposes several control parameters that make it easy to distribute load, have operation flow control, vary granularity at different layers and tune performance to the underlying machine and network. Range-queries are implemented in a way that parallelizes the operation and takes advantage of the recursive properties of the skip list structure. We investigate a shortcut mechanism that alleviates the bottleneck at the head and introduces semantic trade offs between performance and consistency. We report on the performance of the skip list on a medium size cluster of two hundred cores with twenty thousand processes.
Uncovering editorial voices : an analysis of the dog stories in the Taiping guangji
Creators: name: Meade, Samantha Amber
Publisher: name: University of British Columbia
Year: 2014

description: Extensive Records of the Taiping Era (Taiping guangji 太平廣記) is an important sourcebook within Chinese medieval literature dating from the 10th century that contains over 500 volumes and thousands of examples of zhiguai, or stories of strange events and anomalies. This study examines thirty-six dog stories within one chapter of Extensive Records of the Taiping Era, “Domesticated and Wild Beasts” (Chu Shou 畜獸), that are split into two sections “Dogs, Part One” (Quan shang 犬上) and “Dogs, Part Two” (Quan xia 犬下). I trace the history of collecting zhiguai, I evaluate the significance of the content of the dog stories, and I reveal a possible reason for the selection and appearance of the specific dog stories. Using literary and folkloric methods of analysis I uncover what I consider to be an editorial voice of the literati that compiled Extensive Records of the Taiping Era, during the late Tang/early Song dynasty. This voice reveals political and philosophical changes introduced in the stories—a desire for knowledge of expanded people and territories, a new presence of scholar-officials, the resurgence of Confucianism, and a promotion of male-dominance—and the sentiments of these changes held by the literati who collected and edited the dog stories.

description: We present a joint experimental and theoretical study on strong-field photo-ionization of sodium atoms using chirped femtosecond laser pulses. By tuning the chirp parameter, selectivity among the population in the highly excited states 5p, 6p, 7p and 5f, 6f is achieved. Different excitation pathways enabling control are identified by simultaneous ionization and measurement of photoelectron angular distributions employing the velocity map imaging technique. Free electron wave packets at an energy of around 1 eV are observed. These photoelectrons originate from two channels. The predominant 2+1+1 Resonance Enhanced Multi-Photon Ionization (REMPI) proceeds via the strongly driven two-photon transition $4s\leftarrow\leftarrow3s$, and subsequent ionization from the states 5p, 6p and 7p whereas the second pathway involves 3+1 REMPI via the states 5f and 6f. In addition, electron wave packets from two-photon ionization of the non-resonant transiently populated state 3p are observed close to the ionization threshold. A mainly qualitative five-state model for the predominant excitation channel is studied theoretically to provide insights into the physical mechanisms at play. Our analysis shows that by tuning the chirp parameter the dynamics is effectively controlled by dynamic Stark-shifts and level crossings. In particular, we show that under the experimental conditions the passage through an uncommon three-state "bow-tie" level crossing allows the preparation of coherent superposition states.

A new twist-3 analysis of the single transverse-spin asymmetry for pion and kaon production at RHIC

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We present a new analysis for the single-transverse spin asymmetry (SSA) for the inclusive pion and kaon productions in the proton-proton collisions measured at RHIC. The framework we use is the collinear factorization in which SSA appears as a twist-3 observable resulting from the multiparton correlations in the hadrons. As a relevant multiparton correlation, we include all the contributions associated with the quark-gluon correlation functions in the transversely polarized proton, i.e., those from the soft-gluon-pole (SGP) and the soft-fermion-pole (SFP). We have found that the SGP contribution alone is insufficient to describe the observed RHIC A_N data and the inclusion of the SFP contribution plays an important role for the improved description of the data. In particular, P_T-dependence of A_N and A_N for K^- have been well described in our new analysis.

Activating Visual Imagination: Ida Fink’s Tangible Narrative
Creators: name: Melcer-Padon, Nourit
Publisher: name: Centro Studi Arti della Modernità | Università degli Studi di Torino
Year: 2018
Subjects: Narrative Techniques, Photography, Imagination, Ida Fink, Holocaust, Memory, Public and Private Spaces

description: Ida Fink’s short story “Traces” is a prime example of the conjuring power of a narrative that makes use of a photograph. Fink relies on the primacy given to the visual sense; in addition, she relies on a pervasive basic assumption regarding photography, namely that photos are faithful to the reality they capture, and correspondingly are endowed with a truth value. Yet the photo described by a witness to Nazi atrocities is perplexing: taken shortly after the murder of the village’s Jews, it is almost completely empty, since the only visible signs of life are the footmarks they left on the snow. Fink nonetheless manages to use this photo in her narrative and turn the existence of the traces’ owners into a tangible presence. Yet the testimony of the last survivor of the village is as fragile and problematic as the photograph is prone to manipulations. Both testimony and photograph perpetuate what cannot be seen, in a manoeuvre that reminds one of Jochen Gerz’s “vanishing memorial,” organically turning the invisible existence of the dead into cobble stones bearing the names of Jewish cemeteries upside down, so we may—or may not—be stepping on a replicated grave-stone. Both Gerz and Fink use barely visible traces as a constitutive middle ground for creator and reader / viewer, to demonstrate that the most powerful of visual capacities must be ceded to imagination.

These models predict the same background evolution as in the LambdaCDM and possess a non-vanishing speed of sound. We provide a very accurate approximation of Phi, valid after the recombination epoch, in the form of a Bessel function of the first kind. This approximation may be useful for a future deeper analysis of Unified Dark Matter scalar field models.

The next-to-leading order hard factors are calculated in the Ji-Ma-Yuan factorization scheme. We further derive the QCD resummation formalisms for these observables following the Collins-Soper-Sterman method. The results are expressed in terms of the collinear correlation functions from initial and/or final state hadrons coupled with the Sudakov form factor containing all order soft-gluon resummation effects. The scheme independent coefficients are calculated up to one-loop order.

description: In this paper I will try to show how photography informs Geoff Dyer’s novel and essay writing, not only by affecting its contents, but mainly by playing a part in the structures and modes of his works, both on the narrative and non-narrative level. Taking the lead from Dyer’s early essay on John Berger, Ways of Telling (1986), I will try to show in what way Berger’s photographic theory shapes Dyer’s most famous novels, The Colour of Memory (1989) and But Beautiful (1991). I will then first follow the steps Dyer trod in perfecting his knowledge of photography up to his producing a substantial and innovative work on the history and criticism of American photography, The Ongoing Moment (2005); then show how, in one of his most recent works, White Sands (2016), he managed to create a form of essay in which his foremost passions, photography and jazz, become an essential feature of the text, just like he did in But Beautiful, yet, this time, without relying on themes and contents.

Our findings seems to suggest a universal form of distribution which presents a good agreement with a one-parameter stretched Gaussian. We also argue that this parameter can give information on music complexity, and consequently it goes towards classifying songs as well as music genres. Additionally, we present statistical evidences that correlation aspects of the songs are directly related with the non-Gaussian nature of their sound amplitude distributions.

description: The structure of transformation semigroups on a finite set is analyzed by introducing a hierarchy of functions mapping subsets to subsets. The resulting hierarchy of semigroups has a corresponding hierarchy of minimal ideals, or kernels. This kernel hierarchy produces a set of tools that provides direct access to computations of interest in probability limit theorems; in particular, finding certain factors of idempotent limit measures. In addition, when considering transformation semigroups that arise naturally from edge colorings of directed graphs, as in the road-coloring problem, the hierarchy produces simple techniques to determine the rank of the kernel and to decide when a given kernel is a right group. In particular, it is shown that all kernels of rank one less than the number of vertices must be right groups and their structure for the case of two generators is described.

The regulatory mechanisms of the maltose transporter
Creators: name: Bao, Huan
Publisher: name: University of British Columbia
Year: 2014

description: ATP-binding cassette (ABC) transporters couple ATP hydrolysis to import and export of a large array of substances across cell membranes in all kingdoms of life. Since the transport reaction consumes cellular energy, substrate translocation mediated by ABC transporters must be regulated according to the requirements of the cell. This thesis uses the Escherichia coli maltose transporter MalFGK2 to understand the regulatory mechanisms of ABC importers. Biochemical and biophysical approaches were employed to investigate how this transport process is modulated by maltose, the maltose-binding protein MalE and the glucose-specific enzyme EIIAGlc. First, I show that ATP facilitates MalE binding to MalFGK2, which forms the complex of MalE-MalFGK2 for efficient maltose transport. In addition, when the external maltose level exceeds that required, maltose is able to limit the maximal transport rate by promoting dissociation of MalE from MalFGK2. Finally, I find that the N-terminal tail of EIIAGlc and acidic phospholipids are essential for the binding of the protein to the MalK dimer, so that cleavage of ATP by MalFGK2 is inhibited. These results, combined with previous genetic, biochemical and structural work, provide valuable insights into our understanding of the regulatory mechanisms of the maltose transport system.
The Narration of Photography on the Example of Selected Famous Photographs
Creators: name: Mamcarz-Plisiecki, Artur
Publisher: name: Centro Studi Arti della Modernità | Università degli Studi di Torino
Year: 2018
Subjects: Photography, Narration, Visual Rhetoric, Visual Analysis

description: In the theory of photography we can find several primarily literary or rhetorical categories. These are terms such as: narration, theme, composition, style, as well as some stylistic means such as: metaphor, comparison, symbol, gradation and others. The same categories will be found in many other areas of art, both visual and verbal. In that case both literature and photography are various forms of communication. The common purpose of them is to tell the audience the fascinating story, to delight, to make moved or to amuse them. The article will be an attempt to answer the question: “What history do photographs tell us?” This is also an attempt to transfer the literary category, “narration” into the visual plane. Of course, this is possible with the assumption that literary and “photographic” narrations use different materials, but have a common essence and purpose—to tell a story that will be interesting and credible to the recipient. In the paper will be used methods of visual rhetoric which is evolving now. This discipline just merges the verbal sphere (in antiquity it was the theory of politic and literary prose) and visual. This is the field which analyses the effect of the message—including the photo on the recipient. It will be an attempt to analyse the narration of photographs by famous photographers like Dorothea Lange, Joe Rosenthal, Marc Riboud, Robert Capa, Charles C. Ebbets, and Kevin Carter.

description: O relatório “Quem consegue pagar as despesas essenciais? Uma análise da pobreza absoluta em Portugal” analisa a pobreza em Portugal através de uma abordagem absoluta. O estudo utiliza os microdados do Inquérito às Despesas das Famílias (IDEF) de 2022 e adapta os métodos de Orshansky e suplementar do United States Census Bureau. Em 2022, a taxa de risco de pobreza absoluta varia entre 8,5% e 12,6%, abaixo dos 16,4% da taxa de risco pobreza relativa. Cerca de 1% da população (perto de 100 mil pessoas) vive em agregados com rendimento insuficiente para cobrir pelos menos o custo do cabaz alimentar essencial.

Photos, Facts and Fiction: Literary Texts and Mechanical Representation

description: As a mechanical mode of representation, both iconic and indexical, photography has a testimonial and documentary power matched only by film and audio recordings. As Roland Barthes put it, “contrary to [language-based] imitations, in Photography, I can never deny that the thing has been there.” Yet “the thing” can be faked, the recording can be manipulated, and the testimonial value of photos can be subverted in many ways. In this article, I examine the various roles that photos can play when connected to literary texts or to graphic novels. Several cases will be discussed: photos as factual documents that complement language in nonfictional literary texts such as autobiographies; deceptive use of photos in fictional texts that try to pass as or imitate factual texts (Wolfgang’s Hildesheimer’s Marbot); non-deceptive use of photos to break the frame of a fictionalized storyworld and assert the real-world reference of the text (Art Spiegelman’s Maus); ambiguous use of photos in texts that hover between the factual and the fictional (W.G. Sebald’s The Emigrants); and the strange case of Orhan Pamuk’s Museum of Innocence, where photos as collector’s items are exhibited in a real-world museum that both refers to the text and remains independent of it, thereby documenting both the fictional and the real world.

description: We present time-resolved photometry of six faint (V>17mag) cataclysmic variables (CVs); one of them is V849 Oph and the others are identified from the Sloan Digital Sky Survey (SDSS J0920+0042, SDSS J1327+6528, SDSS J1227+5139, SDSS J1607.02+3623, SDSS J1457+5148). The optical CCD photometric observations of these objects were performed at the TÜBİTAK National Observatory (Turkey) between February 2006 and March 2009. We aimed to detect short time scale orbital variability arisen from hot-spot modulation, flickering structures which occur from rapid fluctuations of material transferring from red star to white dwarf and orbital period changes for selected short-period (P<4h) CVs at quiescence. Results obtained from eclipse timings and light curves morphology related to white dwarf stars, accretion disks and hot-spots are discussed for each system. Analysis of the short time coverage of data, obtained for SDSS J1227+5139 indicates a cyclical period change arisen from magnetic activity on the secondary star. Photometric period of SDSS J1607+3623 is derived firstly in this study, while for the other five systems light elements are corrected using the previous and new photometric observations. The nature of SDSS J1457+5148 is not precisely revealed that its light curve shows any periodicity that could be related to the orbital period.

Infrared scaling solutions beyond the Landau gauge: The maximally Abelian gauge and Abelian infrared dominance

description: Functional equations like exact renormalization group and Dyson-Schwinger equations have contributed to a better understanding of non-perturbative phenomena in quantum field theories in terms of the underlying Green functions. In Yang-Mills theory especially the Landau gauge has been used, as it is the most accessible gauge for these methods. The growing understanding obtained in this gauge allows to proceed to other gauges in order to obtain more information about the relation of different realizations of the confinement mechanism. In the maximally Abelian gauge first results are very encouraging as a variant of Abelian infrared dominance is found: The Abelian part of the gauge field propagator is enhanced at low momenta and thereby dominates the dynamics in the infrared. Its role is therefore similar to that of the ghost propagator in the Landau gauge, where one denotes the corresponding phenomenon as ghost dominance. Also the ambiguity of two different types of solutions (decoupling and scaling) exists in both gauges. Here we present how the two solutions are related in the maximally Abelian gauge. The intricacy of the system of functional equations in this gauge required the development of some new tools and methods as, for example, the automated derivation of the equations by the program DoFun. We also present results for linear covariant and ghost anti-ghost symmetric gauges.

Trading strategies and return patterns in commodity futures markets

description: This PhD thesis analyzes commodity futures pricing, trading activities in commodity futures contracts and their use for investment strategies. The aim of this thesis is to fill important gaps in the research field of commodity markets and to highlight special characteristics of commodity futures. It consists of three main chapters which are based on three research papers. The first paper Smart Beta Strategies on Commodity Futures Markets analyzes the use of commodity futures for passive long-only factor investment strategies. It builds on the idea of using factor investment strategies, sometimes also called smart beta strategies, in the space of commodity futures markets. This paper identifies and analyzes eight different types of smart beta strategies, including equal-weight, low-volatility, momentum and term-structure strategies. Term structure strategies can provide an excess return of up to 25% p.a. in the sample-period and prove to be a very attractive investment strategy. These results also cannot be explained by known equity or bond risk-factors. These results highlight the possible information content of the term structure of futures prices and also provide the idea for the second research paper. The second paper A Factor Decomposition of Term Premiums in Commodity Futures Markets examines the term structure of expected commodity futures returns on a theoretical and empirical basis. We use a 3-factor model, which is based on the Cortazar N-factor model, to decompose commodity futures term premiums into a constant, a linear and a non-linear function for the time to expiry. We show that commodity futures returns for maturities of one month and up to twelve months are well explained by this model. Furthermore the information of this model can also be used for profitable long-short trading strategies with Sharpe ratios up to 0.93. The third paper Short Term Commodity Futures Contracts: Trading Patterns and Returns analyzes the specific behaviour of commodity futures in the last trading months, when trading activity is possibly influenced by the physical delivery process. The physical delivery process is usually avoided by financial investors. In our study we analyze trading patterns in volume, open interest and futures returns based on differences in the timing of the physical delivery process for different commodities. We find that the notice day presents an important turning point for every commodity futures contract, when the contract turns from an actively traded contract to a very illiquid contract. Furthermore, we also show that long investors who are willing to run the risk of physical delivery can earn a risk premium during the notice period.
High-fidelity local addressing of trapped ions and atoms by composite sequences of laser pulses

description: A vital requirement for a quantum computer is the ability to locally address, with high fidelity, any of its qubits without affecting their neighbors. We propose an addressing method using composite sequences of laser pulses, which reduces dramatically the addressing error in a lattice of closely spaced atoms or ions, and at the same time significantly enhances the robustness of qubit manipulations. To this end, we design novel high-fidelity composite pulses for the most important single-qubit operations. In principle, this method allows one to beat the diffraction limit, for only atoms situated in a small spatial region around the center of the laser beam are excited, well within the laser beam waist.
