description: To harness the potential of advanced computing technologies, efficient (real time) analysis of large amounts of data is as essential as are front-line simulations. In order to optimise this process, experts need to be supported by appropriate tools that allow to interactively guide both the computation and data exploration of the underlying simulation code. The main challenge is to seamlessly feed the user requirements back into the simulation. State-of-the-art attempts to achieve this, have resulted in the insertion of so-called check- and break-points at fixed places in the code. Depending on the size of the problem, this can still compromise the benefits of such an attempt, thus, preventing the experience of real interactive computing. To leverage the concept for a broader scope of applications, it is essential that a user receives an immediate response from the simulation to his or her changes. Our generic integration framework, targeted to the needs of the computational engineering domain, supports distributed computations as well as on-the-fly visualisation in order to reduce latency and enable a high degree of interactivity with only minor code modifications. Namely, the regular course of the simulation coupled to our framework is interrupted in small, cyclic intervals followed by a check for updates. When new data is received, the simulation restarts automatically with the updated settings (boundary conditions, simulation parameters, etc.). To obtain rapid, albeit approximate feedback from the simulation in case of perpetual user interaction, a multi-hierarchical approach is advantageous. Within several different engineering test cases, we will demonstrate the flexibility and the effectiveness of our approach.

description: Domain-wall solutions in four-dimensional supersymmetric field theories with distinct discrete vacuum states lead to the spontaneous breaking of supersymmetry, either completely or partially. We consider in detail the case when the domain walls are the BPS-saturated states, and 1/2 of supersymmetry is preserved. Several useful criteria that relate the preservation of 1/2 of supersymmetry on the domain walls to the central extension appearing in the N=1 superalgebras are established. We explain how the central extension can appear in N=1 supersymmetry and explicitly obtain the central charge in various models: the generalized Wess-Zumino models, and supersymmetric Yang-Mills theories with or without matter. The BPS-saturated domain walls satisfy the first-order differential equations which we call the creek equations, since they formally coincide with the (complexified) equations of motion of an analog high-viscosity fluid on a profile which is given by the superpotential of the original problem. Some possible applications are considered.

Publisher: name: Monash University

Subjects: subject: 90599 Civil Engineering not elsewhere classified
subject: FOS: Civil engineering

description: This thesis investigates the interaction between nonlinear guided waves and fatigue crack at its initiation in metallic pipes. Literature review in terms of guided wave propagation and interaction with damage through linear and nonlinear characteristics in pipe structures are introduced. Theoretical analysis is extended from plate-like to pipe-like scenario and a proper nonlinear index is developed to assess the severity of fatigue crack of a pipe. The detection of fatigue crack in pipe structures with second harmonic generation method is then conducted numerically and experimentally. The relation between crack length and nonlinearity induced by a fatigue crack is assessed quantitatively.

description: We study the influence of weak periodic signals on the transport properties of underdamped ratchets. We find that the constant current intervals related to the ratchet, can be significantly enlarged by a weak subharmonic signal which is in phase with the internal driver. This stabilization phenomenon is found to exist both in absence and in presence of noise. The dependence of this effect on the phase of the applied signal is also investigated.

description: A naked singularity is formed by the collapse of a Sine-Gordon soliton in 1+1 dimensional dilaton gravity with a negative cosmological constant. We examine the quantum stress tensor resulting from the formation of the singularity. Consistent boundary conditions require that the incoming soliton is accompanied by a flux of incoming radiation across past null infinity, but neglecting the back reaction of the spacetime leads to the absurd conclusion that the total energy entering the system by the time the observer is able to receive information from the singularity is infinite. We conclude that the back reaction must prevent the formation of the naked singularity.

description: When a multifactor experiment is carried out over a period of time, the responses may depend on a time trend. Unless the tests of the experiment are conducted in proper order, the time trend has a negative impact on the precision of the estimates of the main effects, the interaction effects, and the quadratic effects. A proper run order, called a trend-robust run order, minimizes the confounding between the effects’ contrast vectors and the time trend’s linear, quadratic, and cubic components. Finding a trend-robust run order is essentially a permutation problem. We develop a multistage approach based on integer programing to find a trend-robust run order for any given design. The multistage nature of our algorithm allows us to prioritize the trend robustness of the main-effect estimates. In the literature, most of the methods used are tailored to specific designs and are not applicable to an arbitrary design. Additionally, little attention has been paid to trend-robust run orders of response surface designs, such as central composite designs, Box–Behnken designs, and definitive screening designs. Our algorithm succeeds in identifying trend-robust run orders for arbitrary factorial designs and response surface designs with two up to six factors.
Dyons as a source of CP and time invariance violation: electric dipole moments and K-meson decays

description: We consider a mechanism by which dyons (electrically charged magnetic monopoles) can produce both a T- and P-odd (i.e. time reversal invariance and parity violating) mixed polarizability beta [defined by Delta E = -beta E.B, where Delta E is the energy change when electric (E) and magnetic (B) fields are applied to a system] and a T- and P-odd interaction between two particles: psi_1-bar gamma_5 psi_1 psi_2-bar psi_2, where the psi_i are electron and quark spinors. The latter can create atomic and neutron electric dipole moments (EDMs). From experimental bounds on these we find limits on the properties of dyons. Our best limit, using the experimental limit for the EDM of the Tl atom, is M |Q g (Q^2 - g^2)|^(-1/4) > 6 GeV, where M is the dyon mass and Q is the electric and g the magnetic charge of the dyons. The contribution of dyons to CP violation in K-meson decays is also estimated.

description: Let $H$ be a semisimple Hopf algebra acting on an Artin-Schelter regular algebra $A$, homogeneously, inner-faithfully, preserving the grading on $A$, and so that $A$ is an $H$-module algebra. When the fixed subring $A^H$ is also AS regular, thus providing a generalization of the Chevalley-Shephard-Todd Theorem, we say that $H$ is a reflection Hopf algebra for $A$. We show that each of the semisimple Hopf algebras $H_{2n^2}$ of Pansera, and $\mathcal{A}_{4m}$ and $\mathcal{B}_{4m}$ of Masuoka is a reflection Hopf algebra for an AS regular algebra of dimension 2 or 3.

description: The worldwide volume and social relevance of migratory processes justify the need to study the psychological acculturation of the host and immigrant populations through a model adapted to the social context in which they develop. Therefore, the main objective of this article is to carry out a review of some of the existing acculturation models (e.g., Berry, Kim, Power, Young, & Bujaki. (1989). Applied Psychology, 38, 185–206; Bourhis, Moïse, Perreault, & Senécal. (1997). International Journal of Psychology, 32(6), 269–386; Piontkowski, Florack, Hoelker, & Obdrzálek. (2000). International Journal of Intercultural Relations, 24, 1–26), ending up with a proposal for a Relative Acculturation Extended Model (RAEM). This theoretical framework gathers some elements from previous models and adds some new ones in order to offer new explanations for the acculturation strategies and attitudes preferred by both the native and immigrant populations. The most relevant contributions of the RAEM can be summarised as, on the one hand, the consideration of different acculturation domains (political, work, economic, family, social, religion and ways of thinking) and on the other, the differentiation between the acculturation strategies adopted in reality and the acculturation attitudes ideally preferred by the groups in contact. This model also takes into account the ethnocultural origin of immigrants and some variables predicting and modulating their acculturation strategies and attitudes.

description: Multi-Criteria Decision Analysis (MCDA) framework is proposed, aiming at the preliminary assessment of different Nature-based Solutions (NbS) for flood risk management. The alternative NbS, i.e., afforestation, basin restoration and creation of intermittently flooding wetlands were assessed on the basis of five evaluation criteria, including: flood mitigation, economic, social and environmental benefits as well as associated benefits offered by ecosystem services. Criteria weights were calculated by employing the Analytical Hierarchy Process (AHP) method. In addition, a ranking system was introduced for assessing the impacts of different alternatives. The suggested assessment approach was tested in a small sub-basin of the transboundary Nestos river, shared by Greece and Bulgaria. Results revealed that the most efficient alternative is afforestation. Moreover, it can be noted that the approach adopted in this analysis may effectively support pre-feasibility studies supporting the holistic assessment of different NbS for flood risk management.

description: The impacts of the carrier-envelope phase (CEP) of a long relativistic tightly-focused laser pulse on the dynamics of a counter-propagating electron beam have been investigated in the, so-called, electron reflection regime, requiring the Lorentz factor of the electron $γ$ to be approximately two orders of magnitudes lower than the dimensionless laser field parameter $ξ$. The electrons are reflected at the rising edge of the laser pulse due to the ponderomotive force of the focused laser beam, and an asymmetric electron angular distribution emerges along the laser polarization direction, which sensitively depends on the CEP of the driving laser pulse for weak radiative stochastic effects. The CEP siganatures are observable at laser intensities of the order or larger than $10^{19}$ W/cm$^2$ and the pulse duration up to 10 cycles. The CEP detection resolution is proportional to the electron beam density and can achieve approximately $0.1^{\circ}$ at an electron density of about $10^{15}$ cm$^{-3}$. The method is applicable for currently available ultraintense laser facilities with the laser peak power from tens of terawatt to multi-petawatt region.

description: Galaxy cluster outskirts mark the transition region from the mildly non-linear cosmic web to the highly non-linear, virialised, cluster interior. It is in this transition region that the intra-cluster medium (ICM) begins to influence the properties of accreting galaxies and groups, as ram pressure impacts a galaxy's cold gas content and subsequent star formation rate. Conversely, the thermodynamical properties of the ICM in this transition region should also feel the influence of accreting substructure (i.e. galaxies and groups), whose passage can drive shocks. In this paper, we use a suite of cosmological hydrodynamical zoom simulations of a single galaxy cluster, drawn from the nIFTy comparison project, to study how the dynamics of substructure accreted from the cosmic web influences the thermodynamical properties of the ICM in the cluster's outskirts. We demonstrate how features evident in radial profiles of the ICM (e.g. gas density and temperature) can be linked to strong shocks, transient and short-lived in nature, driven by the passage of substructure. The range of astrophysical codes and galaxy formation models in our comparison are broadly consistent in their predictions (e.g. agreeing when and where shocks occur, but differing in how strong shocks will be); this is as we would expect of a process driven by large-scale gravitational dynamics and strong, inefficiently radiating, shocks. This suggests that mapping such shock structures in the ICM in a cluster's outskirts (via e.g. radio synchrotron emission) could provide a complementary measure of its recent merger and accretion history.

Two-point Functions and Quantum Fields in de Sitter Universe

Year: 1995
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We present a theory of general two-point functions and of generalized free fields in d-dimensional de Sitter space-time which closely parallels the corresponding minkowskian theory. The usual spectral condition is now replaced by a certain geodesic spectral condition, equivalent to a precise thermal characterization of the corresponding ``vacuum''states. Our method is based on the geometry of the complex de Sitter space-time and on the introduction of a class of holomorphic functions on this manifold, called perikernels, which reproduce mutatis mutandis the structural properties of the two-point correlation functions of the minkowskian quantum field theory. The theory contains as basic elementary case the linear massive field models in their ``preferred'' representation. The latter are described by the introduction of de Sitter plane waves in their tube domains which lead to a new integral representation of the two-point functions and to a Fourier-Laplace type transformation on the hyperboloid. The Hilbert space structure of these theories is then analysed by using this transformation. In particular we show the Reeh-Schlieder property. For general two-point functions, a substitute to the Wick rotation is defined both in complex space-time and in the complex mass variable, and substantial results concerning the derivation of Kallen-Lehmann type representation are obtained.

description: The spherically symmetric reduction of higher dimensional Einstein-scalar theory leads to lower dimensional dilatonic gravity with dilaton coupled scalar (for example, from 4D to 2D system). We calculate trace anomaly and anomaly induced effective action for 2D and 4D dilaton coupled scalars. The large-N effective action for 2D quantum dilaton-scalar gravity is also found. These 2D results maybe applied for analysis of 4D spherical collapse. The role of new, dilaton dependent terms in trace anomaly for 2D black holes and Hawking radiation is investigated in some specific models of dilatonic gravity which represent modification of CGHS model. The conformal sector for 4D dilatonic gravity is constructed. Quantum back-reaction of dilaton coupled matter is briefly discussed (it may lead to the inflationary Universe with non-trivial dilaton).

description: We look into the newly observed $Ω(2012)$ state from the molecular perspective in which the resonance is generated from the $\bar{K} Ξ^*$, $ηΩ$ and $\bar{K} Ξ$ channels. We find that this picture provides a natural explanation of the properties of the $Ω(2012)$ state. We stress that the molecular nature of the resonance is revealed with a large coupling of the $Ω(2012)$ to the $\bar{K} Ξ^*$ channel, that can be observed in the $Ω(2012) \rightarrow \bar{K} πΞ$ decay which is incorporated automatically in our chiral unitary approach via the use of the spectral function of $Ξ^*$ in the evaluation of the $\bar{K} Ξ^*$ loop function.

description: The magnetic properties of the ferromagnetic Kondo-lattice model (FKLM) are investigated. Starting from an analysis of the magnon spectrum in the spin-wave regime, we examine the ferromagnetic stability as a function of the occupation of the conduction band $n$ and the strength $J$ of the coupling between the localised moments and the conduction electrons. From the properties of the spin-wave stiffness $D$ the ferromagnetic phase at zero temperature is derived. Using an approximate formula the critical temperature $T_c$ is calculated as a function of $J$ and $n$.

description: This article develops new techniques for understanding the relationship between the three different mathematical formulations of two-dimensional chiral conformal field theory: conformal nets (axiomatizing local observables), vertex operator algebras (axiomatizing fields), and Segal CFTs. It builds upon previous work which introduced a geometric interpolation procedure for constructing conformal nets from VOAs via Segal CFT, simultaneously relating all three frameworks. In this article, we extend this construction to study the relationship between the representation theory of conformal nets and the representation theory of vertex operator algebras. We define a correspondence between representations in the two contexts, and show how to construct representations of conformal nets from VOAs. We also show that this correspondence is rich enough to relate the respective 'fusion product' theories for conformal nets and VOAs, by constructing local intertwiners (in the sense of conformal nets) from intertwining operators (in the sense of VOAs). We use these techniques to show that all WZW conformal nets can be constructed using our geometric interpolation procedure.

The Embedding Model of Induced Gravity with Bosonic Sources
Creators: name: Pavsic, Matej
Publisher: name: arXiv
Year: 1995
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We consider a theory in which spacetime is an n-dimensional surface $V_n$ embedded in an $N$-dimensional space $V_N$. In order to enable also the Kaluza-Klein approach we admit $n > 4$. The dynamics is given by the minimal surface action in a curved embedding space. The latter is taken, in our specific model, as being a conformally flat space. In the quantization of the model we start from a generalization of the Howe-Tucker action which depends on the embedding variables $η^a (x)$ and the (intrinsic) induced metric $g_{μν}$ on $V_n$. If in the path integral we perform only the functional integration over $η^a (x)$, we obtain the effective action which functionally depends on $g_{μν}$ and contains the Ricci scalar $R$ and its higher orders $R^2$ etc. But due to our special choice of the conformal factor in $V_N$ enterig our original action, it turns out that the effective action contains also the source term. The latter is in general that of a $p$-dimensional membrane ($p$-brane); in particular we consider the case of a point particle. Thus, starting from the basic fields $η^a (x)$, we induce not only the kinetic term for $g_{μν}$, but also the "matter" source term.

The worldwide volume and social relevance of migratory processes justify the need to study the psychological acculturation of the host and immigrant populations through a model adapted to the social context in which they develop. Therefore, the main objective of this article is to carry out a review of some of the existing acculturation models (e.g., Berry, Kim, Power, Young, & Bujaki. (1989). Applied Psychology, 38, 185–206; Bourhis, Moïse, Perreault, & Senécal. (1997). International Journal of Psychology, 32(6), 269–386; Piontkowski, Florack, Hoelker, & Obdrzálek. (2000). International Journal of Intercultural Relations, 24, 1–26), ending up with a proposal for a Relative Acculturation Extended Model (RAEM). This theoretical framework gathers some elements from previous models and adds some new ones in order to offer new explanations for the acculturation strategies and attitudes preferred byboth the native and immigrant populations. The most relevant contributions of the RAEM can be summarised as, on the one hand, the consideration of different acculturation domains (political, work, economic, family, social, religion and ways of thinking) and on the other, the differentiation between the acculturation strategies adopted in reality and the acculturation attitudes ideally preferred by the groups in contact. This model also takes into account the ethnocultural origin of immigrants and some variables predicting and modulating their acculturation strategies and attitudes.

description: The cross section for dijet photoproduction at high transverse energies is presented as a function of the transverse energies and the pseudorapidities of the jets. The measurement is performed using a sample of ep-interactions corresponding to an integrated luminosity of 6.3 pb^(-1), recorded by the ZEUS detector.Jets are defined by applying a k_T-clustering algorithm to the hadrons observed in the final state. The measured cross sections are compared to next-to-leading order QCD calculations. In a kinematic regime where theoretical uncertainties are expected to be small, the measured cross sections are higher than these calculations.

Determining VA physician requirements through empirically based models.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1995

description: As part of a project to estimate physician requirements for the Department of Veterans Affairs, the Institute of Medicine (IOM) developed and tested empirically based models of physician staffing, by specialty, that could be applied to each VA facility. These analyses used selected data on all patient encounters and all facilities in VA's management information systems for FY 1989. Production functions (PFs), with patient workload dependent on physicians, other providers, and nonpersonnel factors, were estimated for each of 14 patient care areas in a VA medical center. Inverse production functions (IPFs), with physician staffing levels dependent on workload and other factors, were estimated for each of 11 specialty groupings. These models provide complementary approaches to deriving VA physician requirements for patient care and medical education. All data were assembled by VA and put in analyzable SAS data sets containing FY 1989 workload and staffing variables used in the PFs and IPFs. All statistical analyses reported here were conducted by the IOM. Existing VA data can be used to develop statistically strong, clinically plausible, empirically based models for calculating physician requirements, by specialty. These models can (1) compare current physician staffing in a given setting with systemwide norms and (2) yield estimates of future staffing requirements conditional on future workload. Empirically based models can play an important role in determining VA physician staffing requirements. VA should test, evaluate, and revise these models on an ongoing basis.

description: Co-orbital bodies are the byproduct of planet formation and evolution, as we know from the Solar System. Although planet-size co-orbitals do not exists in our planetary system, dynamical studies show that they can remain stable for long periods of time in the gravitational well of massive planets. Should they exist, their detection is feasible with the current instrumentation. In this paper, we present new ground-based observations searching for these bodies co-orbiting with nine close-in (P<5 days) planets, using different observing techniques. The combination of all of them allows us to restrict the parameter space of any possible trojan in the system. We use multi-technique observations (radial velocity, precision photometry and transit timing variations), both newly acquired in the context of the TROY project and publicly available, to constrain the presence of planet-size trojans in the Lagrangian points of nine known exoplanets. We find no clear evidence of trojans in these nine systems through any of the techniques used down to the precision of the observations. However, this allows us to constrain the presence of any potential trojan in the system, specially in the trojan mass/radius versus libration amplitude plane. In particular, we can set upper mass limits in the super-Earth mass regime for six of the studied systems.

Strong enhancement of superconductivity in a nanosized Pb bridge

description: In recent experiments with a superconducting nanosized Pb bridge formed between a scanning tunneling microscope tip and a substrate, superconductivity has been detected at magnetic fields, which are few times larger than the third (surface) critical field. We describe the observed phenomenon on the basis of a numerical solution of the Ginzburg-Landau equations in a model structure consisting of six conoids. The spatial distribution of the superconducting phase is shown to be strongly inhomogeneous, with concentration of the superconducting phase near the narrowest part (the ``neck'') of the bridge. We show that suppression of superconductivity in the bridge by applied magnetic field or by temperature first occurs near the bases and then in the neck region, what leads to a continuous superconducting-to-normal resistive transition. A position of the transition midpoint depends on temperature and, typically, is by one order of magnitude higher than the second critical field H_c2. We find that the vortex states can be realized in the bridge at low temperatures T/T_c < 0.6. The vortex states lead to a fine structure of the superconducting-to-normal resistive transition. We also analyze vortex states in the bridge, which are characterized by a varying vorticity as a function of the bridge's height.

description: In many-body chaotic systems, the size of an operator generically grows in Heisenberg evolution, which can be measured by certain out-of-time-ordered four-point functions. However, these only provide a coarse probe of the full underlying operator growth structure. In this article we develop a methodology to derive the full growth structure of fermionic systems, that also naturally introduces the effect of finite temperature. We then apply our methodology to the SYK model, which features all-to-all $q$-body interactions. We derive the full operator growth structure in the large $q$ limit at all temperatures. We see that its temperature dependence has a remarkably simple form consistent with the slowing down of scrambling as temperature is decreased. Furthermore, our finite-temperature scrambling results can be modeled by a modified epidemic model, where the thermal state serves as a vaccinated population, thereby slowing the overall rate of infection.

Cout du crédit et Pauvreté en zone CEMAC
Creators: name: OBIANG OBIANG Jean Robert
Publisher: name: Zenodo

description: La littérature attestent qu’un coût du crédit élevé est de nature à augmenter la pauvreté dans les pays en développement. Toutefois, elle reste muette quant à la limite à ne pas dépasser si un pays veut s’engager dans la lutte contre ce phénomène. En appliquant une modélisation à changement de régime dans le cadre des pays de la CEMAC, nous trouvons qu’il existe des limites du coût du crédit pour le Gabon, le Cameroun, la Guinée-Equatoriale, le Tchad et la RCA. De tels seuils, étant inférieurs au taux d’intérêt appliqués en pratique, sont la preuve que le secteur bancaire n’est pas capable de soutenir le développement dans la zone. Nous préconisons donc une meilleure promotion du secteur de la microfinance qui constitue l’atout nécessaire pour une inclusion financière efficace.
Alternative mass shell renormalization for minimal supersymmetric Higgs sector

description: An Aoki-Denner form of the renormalization scheme is suggested for the physical amplitudes in MSSM. The Higgs sector is reparameterized with the mass of the CP odd scalar, and the mass of the heavy CP even one instead of $tanβ$ in our scheme. The counterterms of $tanβ$ is fixed perturbatively on mass shell just within Higgs sector. The counterterms of gauge-scalar mixings are defined with Ward-Takahashi identit ies from scalar-scalar mixings. The effect of the reparameterization is also probed on the radiative correction of the mass of the lightest Higgs.
