description: Adding a small subdominant quadratic in momentum term to a dominant linear Dirac dispersion curve affects conduction and valence band differently and leads to an hourglass-like structure for energy as a function of momentum. This applies to the protected surface states in topological insulators. The energies of the conduction and valence band Landau levels are also different and this leads to the splitting of optical absorption lines produced by the magnetic field, which acquire a two peak structure. It also changes the peaks in the imaginary part of the Hall conductivity into two distinct contributions of opposite signs. The real part of the circularly polarized optical conductivity however retains its single peak structure but the peaks in right and left handedness case are shifted in energy with respect to each other in contrast to the pure Dirac case. The magnitude of the semiclassical cyclotron frequency is significantly modified by the presence of a mass term as is its variation with value of the chemical potential $μ$. Its optical spectral weight is found to decrease with increasing $μ$ rather than increase as it does in the pure Dirac limit.

description: AGT correspondence and its generalizations attracted a great deal of attention recently. In particular it was suggested that $U(r)$ instantons on $R^4/Z_p$ describe the conformal blocks of the coset ${\cal A}(r,p)=U(1)\times sl(p)_r\times {sl(r)_p\times sl(r)_n\over sl(r)_{n+p}}$, where $n$ is a parameter. Our purpose here is to describe Generalized Rogers Ramanujan (GRR) identities for these cosets, which expresses the characters as certain $q$ series. We propose that such identities exist for the coset ${\cal A}(r,p)$ for all positive integers $n$ and all $r$ and $p$. We treat here the case of $n=1$ and $r=2$, finding GRR identities for all the characters.

description: Das digitale Zeitalter und der damit verknüpfte Medienwandel hinterlassen weitreichende Spuren im Journalismus. Dieser entwickelt sich immer mehr zu einem Feld der Partizipation durch Außenstehende. Ziel dieser Arbeit war die Analyse der Rezeption von Bürgerjournalismus im Zuge der Nachrichtenberichterstattung. Im Fokus standen dabei zwei Forschungsfragen, die sich mit der Wahrnehmung zweier Generationen von Bürgerjournalismus in unterschiedlichen Medienformaten sowie den Auswirkungen von Bürgerjournalismus auf das Bild von Journalist:innen allgemein befassen. Um diese Forschungsfragen zu beantworten, wurden zwölf qualitative Leitfadeninterviews mit Personen aus der Generation X und der Generation Z geführt. Im Rahmen einer strukturierenden Inhaltsanalyse wurden die Antworten analysiert und anhand eines Kategorienschemas dargestellt. Die Interviews wurden sowohl persönlich als auch via Telefon durchgeführt. Aus den Ergebnissen der Arbeit können folgende Schlussfolgerungen gezogen werden: Bürgerjournalismus wird vor allem im Internet als wenig vertrauenswürdig erachtet aufgrund der vorherrschenden Anonymität von Nachrichtenverfasser:innen sowie nicht vorhandener Nachvollziehbarkeit der Quellen. Bürgerjournalismus führt dazu, dass Akteur:innen im Journalismus, die nicht als professionell gelten, jegliche journalistischen Standards wie Transparenz, Faktencheck und Quellenangaben abgesprochen werden.
description: The digital age and the associated change in the media are leaving far-reaching traces in journalism. Journalism is increasingly developing into a field of participation by outsiders. The aim of this work was to analyze the reception of citizen journalism in the course of news reporting. The focus was on two research questions dealing with the perception of two generations of citizen journalism in different media formats and the impact of citizen journalism on the image of journalists in general. In order to answer these research questions, twelve qualitative guided interviews were conducted with individuals from Generation X and Generation Z. The interviews were conducted in the context of a structuring content analysis. Within the framework of a structuring content analysis, the answers were analyzed and presented using a category scheme. The interviews were conducted both in person and via telephone. The following conclusions can be drawn from the results of the work: Citizen journalism is considered untrustworthy, especially on the Internet, due to the predominant anonymity of news authors and the lack of traceability of sources. Citizen journalism leads to the denial of any journalistic standards such as transparency, fact-checking and source citation to actors in journalism who are not considered professional.
On error operators related to the arbitrary functions principle

description: The error on a real quantity Y due to the graduation of the measuring instrument may be asymptotically represented, when the graduation is regular and fines down, by a Dirichlet form on R whose square field operator does not depend on the probability law of Y as soon as this law possesses a continuous density. This feature is related to the "arbitrary functions principle" (Poincar'e, Hopf). We give extensions of this property to Rd and to the Wiener space for some approximations of the Brownian motion. This gives new approximations of the Ornstein-Uhlenbeck gradient. These results apply to the discretization of some stochastic differential equations encountered in mechanics.

description: From energy conservation perspective inWireless Sensor Networks (WSNs), clustering of sensor nodes is a challenging task. Clustering technique in routing protocols play a key role to prolong the stability period and lifetime of the network. In this paper, we propose and evaluate a new routing protocol for WSNs. Our protocol; Divide-and-Rule (DR) is based upon static clustering and dynamic Cluster Head (CH) selection technique. This technique selects fixed number of CHs in each round instead of probabilistic selection of CH. Simulation results show that DR protocol outperform its counterpart routing protocols.

description: Das Ziel dieser Arbeit ist es, die Versprachlichung von weiblicher* Sexualität in ausgewählten Romanen der Gegenwartsliteratur, in denen Sexualität und sexuelle Handlungen der zentrale Fokus ist, zu analysieren. Dazu wird die folgende Forschungsfrage gestellt: Mit welchen Sexualsprachgebrauch und welchen sprachlichen Mitteln wird weibliche* Sexualität in Romanen mit weiblichen* Protagonist*innen versprachlicht, welche Machtverhältnisse, und Sexualitätskonzepte werden dabei beschrieben und welche Sexualnormen werden dabei thematisiert, dekonstruiert, kritisiert, destabilisiert oder erweitert? Um die Forschungsfrage zu beantworten, wurde eine linguistische Analyse der Lexik und Metaphorik der verwendeten Sexualsprache und eine hermeneutische literaturwissenschaftliche Analyse durch die Praktik des close readings der Romane „Feuchtgebiete“ von Charlotte Roche, „Unter meinen Händen“ von Karen-Susan Fessel und „Hautfreundin“ von Doris Anselm durchgeführt. Die Untersuchung zeigte, dass es bei der Versprachlichung von Sexualität in den Romanen trotz unterschiedlichem Sexualsprachvokabulars zu wesentlichen Ähnlichkeiten in den verwendeten sprachlichen Mitteln kam. Jedes der Werke legte lexikalisch wie semantisch einen Fokus auf den weiblichen* Körper und die weibliche* Lust und in beinahe allen Sexualitätsbeschreibungen wurden gleichberechtigte Machtverhältnisse durch die Verwendung von standardsexualsprachlichen und obszön-vulgärsexualsprachlichen Plural-Verbenhergestellt. Alle Romane zeigten die Tendenz, non-normative oder als obszön wahrgenommene sexuelle Praktiken durch wertschätzende oder positive Beschreibungen aufzuwerten und dabei Sexualnormen explizit oder implizit zu thematisieren. Dies zeigt, dass in Darstellungen von lustvoller weiblicher* Sexualität positive Alternativen von-normativer weiblicher* Sexualität in Koexistenz mit einer Kritik von Sexualnormen geschildert werden und die verwendete Sexualsprache dabei zur Kritik der Normen oder zur Normalisierung der Normabweichungen verwendet wird.

description: We study the quantum evolution of a cloud of hard-core bosons loaded on a one-dimensional optical lattice after its sudden release from a harmonic trap. Just after the trap has been removed, a linear ramp potential is applied, mimicking the so called Galileo ramp experiment. The non-equilibrium expansion of the bosonic cloud is elucidated through a hydrodynamical description which is compared to the exact numerical evolution obtained by exact diagonalization on finite lattice sizes. The system is found to exhibit a rich behavior showing in particular Bloch oscillations of a self-trapped condensate and an ejected particle density leading to two diverging entangled condensates. Depending on the initial density of the gas different regimes of Josephson-like oscillations are observed. At low densities, the trapped part of the cloud is in a superfluid phase that oscillates in time as a whole. At higher densities, the trapped condensate is in a mixed superfluid-Mott phase that show a breathing regime for steep enough potential ramps.

description: The drastic effect of local alliances in three-party competition is investigated in democratic hierarchical bottom-up voting. The results are obtained analytically using a model which extends a sociophysics frame introduced in 1986 \cite{psy} and 1990 \cite{lebo} to study two-party systems and the spontaneous formation of democratic dictatorship. It is worth stressing that the 1990 paper was published in the Journal of Statistical Physics, the first paper of its kind in the journal. It was shown how a minority in power can preserve its leadership using bottom-up democratic elections. However such a bias holds only down to some critical value of minimum support. The results were used latter to explain the sudden collapse of European communist parties in the nineties. The extension to three-party competition reveals the mechanisms by which a very small minority party can get a substantial representation at higher levels of the hierarchy when the other two competing parties are big. Additional surprising results are obtained, which enlighten the complexity of three-party democratic bottom-up voting. In particular, the unexpected outcomes of local voting alliances are singled out. Unbalanced democratic situations are exhibited with strong asymmetries between the actual bottom support of a party and its associated share of power at the top leadership. Subtle strategies are identified for a party to maximize its hold on the top leadership. The results are also valid to describe opinion dynamics with three competing opinions.

title: Implosion auf dem Balkan
Creators: name: Pably, David
Year: 2022

description: Die vorliegende Masterarbeit untersucht Deutungsmuster zur Erklärung des staatlichen Zusammenbruchs Großrumäniens im Sommer 1940. Dabei werden nach der Methode eines "Literature Review" sowohl relevante Beiträge aus der Sekundärliteratur als auch hermeneutisch analysierte Quellenausschnitte interpretiert. Der Verfasser argumentiert im Text für die sogenannte Implosionsthese, welche davon ausgeht, dass eine massiv defizitäre Verfasstheit der Demokratie sowie die Aushöhlung staatlicher Strukturen sowohl durch eine korrumpierte Elite als auch durch einen autoritär eingestellten König dazu führte, dass das Politsystem dem Druck von außen nicht standhalten konnte. In diesem Zusammenhang spielten einerseits die Struktur des Landes als kompositer und postimperialer Vielvölkerstaat und andererseits der rasante Aufstieg des rumänischen Faschismus eine außerordentliche Rolle. Relativiert wird vom Verfasser hingegen die Aggressionsthese, welche vor allem von Historikern nationalistischer Prägung vertreten wird, deren Anliegen es ist, den Zusammenbruch des Landes über die persönliche Unfähigkeit des Königs in Kombination mit einer schier aussichtlosen außenpolitischen Lage zu erklären, während das politische System und dessen Eliten zumeist als erfolgreiche Experimentierphase dargestellt werden. Der bis in die Gegenwart andauernde Kampf um die vermeintlich richtige Auslegung rumänischer Zeitgeschichte muss in diesem Zusammenhang als Ausdruck eines fehlenden Reflexionswillens infolge jahrzehntelanger Prägung durch eine kommunistische Einparteienherrschaft verstanden werden. Terminologisch wird die Zuschreibung „faschistoid“ als für das vorliegende Königsregime angemessener Begriff festgemacht. Dieses war geprägt von einem Versuch der totalen Erfassung der Gesellschaft, insbesondere der Jugend, einer symbolischen Nachahmung in erster Linie des italienischen Faschismus sowie eine starke spirituelle Note durch die Einbindung des rumänisch-orthodoxen Patriarchats. In diesem Sinne wird das entsprechende Herrschaftssystem als „Monarchokratie“ nach Sundhausen definiert und entlang der von Stanley Payne definierten Kriterien des Faschismus als rechtsautoritäres Regime innerhalb eines gesamteuropäischen Rahmens eingeordnet.
title: Kulturalisierung von Gewalt am Beispiel der Berichterstattung über die Übergriffe auf Frauen während der Silvesternacht in Köln 2015/16
Creators: name: Mehrwald, Anna Katarina
Year: 2022

description: Die sexuellen Übergriffe auf Frauen in der Kölner Silvesternacht stellen ein vielfach debattiertes Ereignis dar, das zur Projektionsfläche für das Ende der deutschen Willkommenskultur geworden ist. Es wird als Bruch in der Diskussion um die Positionierung Deutschlands in der Flüchtlingsfrage verstanden und von der deutschen Regierung zum Anlass genommen, restriktivere Asylgesetze einzufordern und zum Teil auch umzusetzen. In der medialen Debatte und auch von politischen Vertreter*innen wird festgehalten, dass die Übergriffe von rechten Akteur*innen instrumentalisiert werden, um mithilfe des Arguments, man müsse Frauen beschützen und die Emanzipation in Deutschland aufrechterhalten, Stimmung gegen Flüchtlinge zu machen. Während die Kulturalisierung von Gewalt und die damit einhergehende Forderung, man solle Einwanderer aus gewissen Kulturen nicht aufnehmen, ein bekanntes Phänomen unter rechten Akteur*innen ist, sind derartige Argumente aus der Mitte der Gesellschaft und von links positionierten Akteur*innen aber als eine Neuerscheinung anzusehen, die nach der Silvesternacht ein gewisses Unbehagen hervorrief. Die vorliegende Arbeit möchte sich mit diesem Unbehagen beschäftigen und sich der These widmen, dass über die Anrufung der Zivilisiertheit und Emanzipation der deutschen Gesellschaft und durch das Argument der Sexismus-Abwehr, auch in nicht dem rechten Politikspektrum zuzuordnenden Gesellschaftsegmenten nationalistische bis rassistische Aussagen über die Vorfälle sagbar wurden. Um sich mit dieser These auseinanderzusetzen wurde die Berichterstattung zweier deutscher Zeitungen, der Süddeutschen Zeitung und der taz, anhand der Critical Frame Analysis analysiert. Die forschungsleitenden Fragen wurden dabei anhand des theoretischen Gerüsts formuliert, welches sich mit antimuslimischem Rassismus, Kulturalisierung von Gewalt und Sexuellem Exzeptionalismus auseinandersetzt.
Variable selection for sparse Dirichlet-multinomial regression with an application to microbiome data analysis

description: With the development of next generation sequencing technology, researchers have now been able to study the microbiome composition using direct sequencing, whose output are bacterial taxa counts for each microbiome sample. One goal of microbiome study is to associate the microbiome composition with environmental covariates. We propose to model the taxa counts using a Dirichlet-multinomial (DM) regression model in order to account for overdispersion of observed counts. The DM regression model can be used for testing the association between taxa composition and covariates using the likelihood ratio test. However, when the number of covariates is large, multiple testing can lead to loss of power. To address the high dimensionality of the problem, we develop a penalized likelihood approach to estimate the regression parameters and to select the variables by imposing a sparse group $\ell_1$ penalty to encourage both group-level and within-group sparsity. Such a variable selection procedure can lead to selection of the relevant covariates and their associated bacterial taxa. An efficient block-coordinate descent algorithm is developed to solve the optimization problem. We present extensive simulations to demonstrate that the sparse DM regression can result in better identification of the microbiome-associated covariates than models that ignore overdispersion or only consider the proportions. We demonstrate the power of our method in an analysis of a data set evaluating the effects of nutrient intake on human gut microbiome composition. Our results have clearly shown that the nutrient intake is strongly associated with the human gut microbiome.

description: The mechanism of emergence of robust quantum criticality in Yb- and Ce-based heavy electron systems under pressure is analyzed theoretically. By constructing a minimal model for quasicrystal Yb15Al34Au51 and its approximant, we show that quantum critical points of the first-order valence transition of Yb appear in the ground-state phase diagram with their critical regimes being overlapped to be unified, giving rise to a wide quantum critical regime. This well explains the robust unconventional criticality observed in Yb15Al34Au51 under pressure. We also discuss broader applicability of this mechanism to other Yb- and Ce-based systems such as beta-YbAlB4 showing unconventional quantum criticality.

The lent particle method for marked point processes

subject: FOS: Mathematics

description: Although introduced in the case of Poisson random measures, the lent particle method applies as well in other situations. We study here the case of marked point processes. In this case the Malliavin calculus (here in the sense of Dirichlet forms) operates on the marks and the point process doesn't need to be Poisson. The proof of the method is even much simpler than in the case of Poisson random measures. We give applications to isotropic processes and to processes whose jumps are modified by independent diffusions.

description: We present the first secondary eclipse and phase curve observations for the highly eccentric hot Jupiter HAT-P-2b in the 3.6, 4.5, 5.8, and 8.0 μm bands of the Spitzer Space Telescope. The 3.6 and 4.5 μm data sets span an entire orbital period of HAT-P-2b, making them the longest continuous phase curve observations obtained to date and the first full-orbit observations of a planet with an eccentricity exceeding 0.2. We present an improved non-parametric method for removing the intrapixel sensitivity variations in Spitzer data at 3.6 and 4.5 μm that robustly maps position-dependent flux variations. We find that the peak in planetary flux occurs at 4.39+/-0.28, 5.84+/-0.39, and 4.68+/-0.37 hours after periapse passage with corresponding maxima in the planet/star flux ratio of 0.1138%+/-0.0089%, 0.1162%+/-0.0080%, and 0.1888%+/-0.0072% in the 3.6, 4.5, and 8.0 μm bands respectively. We compare our measured secondary eclipse depths to the predictions from a one-dimensional radiative transfer model, which suggests the possible presence of a transient day side inversion in HAT-P-2b's atmosphere near periapse. We also derive improved estimates for the system parameters, including its mass, radius, and orbital ephemeris. Our simultaneous fit to the transit, secondary eclipse, and radial velocity data allows us to determine the eccentricity and argument of periapse of HAT-P-2b's orbit with a greater precision than has been achieved for any other eccentric extrasolar planet. We also find evidence for a long-term linear trend in the radial velocity data. This trend suggests the presence of another substellar companion in the HAT-P-2 system, which could have caused HAT-P-2b to migrate inward to its present-day orbit via the Kozai mechanism.

title: Mit Politikinstrumenten zur Arbeitszeitverkürzung?
Creators: name: Pauer, Agnes Karoline
Year: 2022

description: Die vorliegende Masterarbeit beschäftigt sich mit der Arbeitszeitverkürzung in Österreich. Sie schlägt Politikinstrumente vor, die bei einer flächendeckenden Arbeitszeitverkürzung bei gleichbleibendem Gehalt in Österreich zum Einsatz kommen könnten. Dafür wird zum einen der Inhalt qualitativer Interviews mit Unternehmenssprechern untersucht, die auf eigene Initiative eine Arbeitszeitverkürzung eingeführt haben, bestehende Literatur analysiert und bisherigen Wegen zur Arbeitszeitverkürzung in Österreich gegenübergestellt. Methodologisch ist diese Arbeit auf der Constructivist Grounded Theory nach Kathy Charmaz (2014) aufgebaut. Diese Vorgehensweise ermöglicht die Theoretisierung von Daten für eine weitere Bearbeitung. Da die Beweggründe von Unternehmen, die auf eigene Initiative eine Arbeitszeitverkürzung in Österreich eingeführt haben, noch nicht erhoben wurden, leisten die Daten dadurch einen ersten Beitrag in diese Richtung. Die Analyse zeigt, dass die Unternehmen eine flächendeckende Arbeitszeitverkürzung nicht unterstützen würden. Das könnte daran liegen, dass jene für die Unternehmen ein Alleinstellungsmerkmal und einen Wettbewerbsvorteil in Zeiten eines branchenübergreifenden Fachkräftemangels bedeutet. Dennoch hätte eine Arbeitszeitverkürzung gesamtgesellschaftliche Vorteile. Abschließend schlägt die Arbeit deshalb vier unterschiedliche Kombinationsarten von Politikinstrumenten vor, an denen für die Umsetzung einer flächendecken Arbeitszeitverkürzung bei gleichbleibendem Gehalt in Österreich weitergeforscht werden kann.
description: This master's thesis deals with the reduction of working hours in Austria. It proposes policy instruments that could be used in the case of a nationwide reduction of working hours at constant salaries in Austria. For this purpose, the content of qualitative interviews with company spokespersons who have introduced a reduction in working hours on their own initiative is examined, existing literature is analyzed and being compared with previous ways of reducing working hours in Austria. Methodologically, this work is based on Constructivist Grounded Theory according to Kathy Charmaz (2014). This approach enables the theorization of data for further processing. Since the motivations of companies that have introduced a reduction in working hours in Austria on their own initiative have not yet been surveyed, the data thereby make a first contribution here. The analysis shows that companies would not support a nationwide reduction in working hours. This could be due to the fact that it represents a unique selling proposition for companies and a competitive advantage in times of a cross-sector shortage of skilled workers. Nevertheless, a reduction in working hours would have benefits for society as a whole. In conclusion, the paper therefore proposes four different combinations of policy instruments on which further research can be conducted for the implementation of a nationwide reduction in working hours at constant salaries in Austria.
Polarization structure in the core of 1803+784: a signature of recollimation shocks?

description: The extragalactic radio source 1803+784 is a BL Lac object that shows rapid variability and strong linear polarization. Very long baseline interferometry observations reveal that the core possesses a distinctive structure in polarized intensity with two maxima on axis and two minima symmetrically placed on either side. The approximately radial pattern of electric field polarization rods is reminiscent of the results obtained earlier by Cawthorne (2006) for conical shocks, but, individually, these do not reproduce the main features of the polarized intensity images. In numerical simulations and experiments, these shocks occur in pairs and help to stabilize jets as they adjust to changes in environment. Here, the polarization resulting from such structures is investigated using an approximate, analytical approach, by making some simple assumptions about the nature of the flow between two such shock waves. For fairly small viewing angles, it is found that a reasonable representation of the core polarization of 1803+784 can be obtained. The similarity between the observed and model polarization supports the view that the core structure in 1803+784 represents a recollimation shock, and that such shock waves may be responsible for the first disturbance and hence brightening of the quiescent flow in astrophysical jets.

description: Self-assembly of structures from vertically aligned, charged dust particle bundles within a glass box placed on the lower, powered electrode of a RF GEC cell were produced and examined experimentally. Self-organized formation of one-dimensional vertical chains, two-dimensional zigzag structures and three-dimensional helical structures of triangular, quadrangular, pentagonal, hexagonal, and heptagonal symmetries are shown to occur. System evolution is shown to progress from a one-dimensional chain structure, through a zigzag transition to a two-dimensional, spindle-like structure and then to various three-dimensional, helical structures exhibiting multiple symmetries. Stable configurations are found to be dependent upon the system confinement, (where are the horizontal and vertical dust resonance frequencies), the total number of particles within a bundle and the RF power. For clusters having fixed numbers of particles, the RF power at which structural transitions occur is repeatable and exhibits no observable hysteresis. The critical conditions for these structural transitions as well as the basic symmetry exhibited by the one-, two- and three-dimensional structures that subsequently develop are in good agreement with the theoretically predicted configurations of minimum energy determined employing molecular dynamics simulations for charged dust particles confined in a prolate, spheroidal potential as presented theoretically by Kamimura and Ishihara [10].

Iteration of the lent particle method for existence of smooth densities of Poisson functionals

description: In previous works we have introduced a new method called the lent particle method which is an efficient tool to establish existence of densities for Poisson functionals. We now go further and iterate this method in order to prove smoothness of densities. More precisely, we construct Sobolev spaces of any order and prove a Malliavin-type criterion of existence of smooth density. We apply this approach to SDE's driven by Poisson random measures and also present some non-trivial examples to which our method applies.

description: Slides used for the Recognition & Rewards Festival 2023, Workshop 1.8 - Recognising supporting roles on the 13th of April 2023. Session contributors listed in alphabetical order. Workshop abstract: The position paper ‘Room for everyone's talent’ focusses, amongst other things, on diversifying career paths and how to recognise team performances. This should be a key opportunity to involve staff at research institutions that have more specialised or supporting tasks in these teams. This workshop aims to increase awareness regarding supporting roles, what role they play in Team Science and how to recognise their expertise. During this interactive workshop we will exchange practices and start with setting up a survey and roadmap to ensure that supporting roles are involved in current and future Recognition and Rewards efforts. Please note that animations were used in the slides, which are properly displayed in the .pptx format.

description: We have studied the processing of piezoelectric thick films using electrophoretic deposition (EPD) for high-frequency ultrasound applications. Lead-zirconium-titanate (PZT) particles synthetized by solid states synthesis were dispersed in ethanol using ammonium polyacrylate (PAA). The electrophoretic deposition of PZT particles was performed at a constant-current mode. PZT thick-films deposited at 1 mA for 60 seconds were sintered at 900oC for 2 hours in a PbO-controlled atmosphere. The scanning-electron microscopy (SEM) analysis shows that the thickness of PZT layer is uniform and that the pores are homogeneously distributed within the layer. The complex electrical impedance was measured and fitted by KLM scheme in order to deduce the dielectric, mechanical and piezoelectric parameters of the thick-films. The density and thickness of PZT thick films are used as inputs and the thickness coupling factor kt, dielectric constant at constant strain and resonant frequency are deduced. The results show that homogeneous PZT thick-film structures with tailored thickness and density prepared by EPD and sintering having a resonant frequency around 20 MHz can be used for noninvasive medical ultrasound imaging and diagnostics.

Drichlet forms for Poisson measures and Lévy processes : the lent particle method
Creators: name: Bouleau, Nicolas
name: Denis, Laurent
Publisher: name: arXiv
Year: 2013
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: We present a new approach to absolute continuity of laws of Poisson functionals. The theoretical framework is that of local Dirichlet forms as a tool to study probability spaces. The method gives rise to a new explicit calculus that we show first on some simple examples : it consists in adding a particle and taking it back after computing the gradient. Then we apply it to SDE's driven by Poisson measure.
Relaxation of flying spin qubits in quantum wires by hyperfine interaction
Creators: name: Echeverria-Arrondo, C.
name: Sherman, E. Ya.
Publisher: name: arXiv
Year: 2013
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We consider the relaxation of a spin qubit in a quantum dot propagating as a whole in a one-dimensional semiconductor with hyperfine coupling. We show that this motion leads to qualitatively new features in this process compared to static quantum dots. For a fast straightforward motion, the initial spin density decreases to zero with the relaxation rate independent of the spatial spread of the electron wave function and inversely proportional to the electron speed. However, for the oscillatory motion, the qubit acquires memory, and the dephasing becomes Gaussian rather than exponential. After some time, one third of the initial spin polarization is restored, as it happens for static qubits. This revival can occur either through periodic peaks or through a monotonous increase in the polarization, after a minimum, until a plateau has been reached. Our results can be useful for the understanding of the spin dynamics and decoherence in quantum wires.

description: The article aims to define the management mechanism of complex, open dynamic systems with human participation. The following parts of the system life-cycle were identified and unified in the theoretical scope: general and specific compositional elements of repeating changes, marginal index boundaries, the dynamics of the compositional elements of the lifecycle, and the key points of the change in the character of the index dynamics. In the practical scope, two common trends of socio-economical system life-cycle management are considered. The first trend is the regulation of the comprising element ratio, which provides an increase in the duration of the maximally effective performance of a functioning system. The second trend is the regulation of the reproduction time of a new system. The systems life cycle aspects are investigated in almost all sciences and studied within many disciplines in the field of higher education. Therefore, deepening the mastery of scientific and methodological foundations of the life cycle of a complex open dynamic system is useful for any subject in everyday and practical activities. A human being – in the formation of own human capital. Families – when it is formed, the birth of children, the distribution of income and expenses. Companies – for efficient business activities. As well as local communities, local self-government bodies, public authorities, and global entities within their profile activities. The results of the research provide the possibility of the development of applicable mechanisms for the effectiveness and stability enhancement of managerial and entrepreneurial operations in business projects.

description: De Haas-van Alphen oscillations are studied for Fermi surfaces illustrating the Pippard's model, commonly observed in multiband organic metals. Field- and temperature-dependent amplitude of the various Fourier components, linked to frequency combinations arising from magnetic breakdown between different bands, are considered. Emphasis is put on the Onsager phase factor of these components. It is demonstrated that, in addition to the usual Maslov index, field-dependent phase factors must be considered to precisely account for the data at high magnetic field. We present compelling evidence of the existence of such contributions for the organic metal theta-(BEDT-TTF)4CoBr4(C6H4Cl2).
