description: In order to generate initial data for nonlinear relativistic simulations, one needs to solve the Einstein constraints, which can be cast into a coupled set of nonlinear elliptic equations. Here we present an approach for solving these equations on three-dimensional multi-block domains using finite element methods. We illustrate our approach on a simple example of Brill wave initial data, with the constraints reducing to a single linear elliptic equation for the conformal factor $ψ$. We use quadratic Lagrange elements on semi-structured simplicial meshes, obtained by triangulation of multi-block grids. In the case of uniform refinement the scheme is superconvergent at most mesh vertices, due to local symmetry of the finite element basis with respect to local spatial inversions. We show that in the superconvergent case subsequent unstructured mesh refinements do not improve the quality of our initial data. As proof of concept that this approach is feasible for generating multi-block initial data in three dimensions, after constructing the initial data we evolve them in time using a high order finite-differencing multi-block approach and extract the gravitational waves from the numerical solution.

Interference effects in interacting quantum dots

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: In this paper we study the interplay between interference effects in quantum dots (manifested through the appearance of Fano resonances in the conductance), and interactions taken into account in the self-consistent Hartree-Fock approximation. In the non-interacting case we find that interference may lead to the observation of more than one conductance peak per dot level as a function of an applied gate voltage. This may explain recent experimental findings, which were thought to be caused by interaction effects. For the interacting case we find a wide variety of different interesting phenomena. These include both monotonous and non-monotonous filling of the dot levels as a function of an applied gate voltage, which may occur continuously or even discontinuously. In many cases a combination of the different effects can occur in the same sample. The behavior of the population influences, in turn, the conductance lineshape, causing broadening and asymmetry of narrow peaks, and determining whether there will be a zero transmission point. We elucidate the essential role of the interference between the dot levels in determining these outcomes. The effects of finite temperatures on the results are also examined.

description: We study theoretically the resonant structure of the double Cabibbo suppressed $D^+\to K^- K^+K^+$ decay. We start from an elementary production diagram, considered subleading in previous approaches, which cannot produce a final $K^- K^+$ pair at the tree level but which we show to be able to provide the strength of the decay through final meson-meson state interaction. The different meson-meson elementary productions are related through SU(3) and the final rescattering is implemented from a suitable implementation of unitary extensions of ChPT which generate dynamically the scalar resonances $f_0(980)$ and $a_0(980)$. We obtain a good agreement with recent experimental data from the LHCb collaboration with a minimal freedom in the fit and show the dominance of the $a_0(980)$ contribution close to the threshold of the $K^- K^+$ spectrum.

Linear and nonlinear absolute phase effects in interactions of ultrashort laser pulses with a metal nano-layer or with a plasma layer

Year: 2006
Subjects: subject: Plasma Physics (physics.plasm-ph)
subject: FOS: Physical sciences

description: It has been shown that in the scattered radiation, generated by an ultrashort laser pulse impinging on a metal nano-layer, non-oscillatory wake-fields appear with a definite sign. The magnitude of these wake-fields is proportional with the incoming field strength, and a sign of them is governed by the cosine of the carrier-envelope phase difference of the incoming pulse. At relativistic laser intensities the target is considered as a plasma layer in vacuum, produced from a thin foil by a pre-pulse, which is followed by the main high-intensity laser pulse. The nonlinearities stemming from the relativistic kinematics of the surface current density (representing the plasma electrons) lead to the appearance of higher-harmonics in the scattered spectra. In general, the harmonic peaks are down-shited due to the presence of an intensity-dependent factor. Certain regions of these spectra are very sensitive to the variation of the carrier-envelope phase difference. The spectra has a long tail where the heigths of the peaks vary practically within one order of magnitude forming a quasi-continuum. By Fourier synthetising the components from this plateau region attosecond pulses have been obtained.

description: We present results from an extensive survey of 64 cavities in the X-ray halos of clusters, groups and normal elliptical galaxies. We show that the evolution of the size of the cavities as they rise in the X-ray atmosphere is inconsistent with the standard model of adiabatic expansion of purely hydrodynamic models. We also note that the majority of the observed bubbles should have already been shredded apart by Rayleigh-Taylor and Richtmyer-Meshkov instabilities if they were of purely hydrodynamic nature. Instead we find that the data agrees much better with a model where the cavities are magnetically dominated and inflated by a current-dominated magneto-hydrodynamic jet model, recently developed by Li et al. (2006) and Nakamura et al. (2006). We conduct complex Monte-Carlo simulations of the cavity detection process including incompleteness effects to reproduce the cavity sample's characteristics. We find that the current-dominated model agrees within 1sigma, whereas the other models can be excluded at >5sigma confidence. To bring hydrodynamic models into better agreement, cavities would have to be continuously inflated. However, these assessments are dependent on our correct understanding of the detectability of cavities in X-ray atmospheres, and will await confirmation when automated cavity detection tools become available in the future. Our results have considerable impact on the energy budget associated with active galactic nucleus feedback.

description: This chapter of the report of the ``Flavour in the era of the LHC'' Workshop discusses the theoretical, phenomenological and experimental issues related to flavour phenomena in the charged lepton sector and in flavour-conserving CP-violating processes. We review the current experimental limits and the main theoretical models for the flavour structure of fundamental particles. We analyze the phenomenological consequences of the available data, setting constraints on explicit models beyond the Standard Model, presenting benchmarks for the discovery potential of forthcoming measurements both at the LHC and at low energy, and exploring options for possible future experiments.

description: We study, by means of numerical lattice simulations, the properties of the reconfinement phase transition taking place in trace deformed $SU(3)$ Yang-Mills theory defined on $\mathbb{R}^3\times S^1$, in which center symmetry is recovered even for small compactification radii. We show, by means of a finite size scaling analysis, that the reconfinement phase transition is first-order, like the usual $SU(3)$ thermal phase transition. We then investigate two different physical phenomena, which are known to characterize the standard confinement/deconfinement phase transition, namely the condensation of thermal magnetic monopoles and the change in the localization properties of the eigenmodes of the Dirac operator. Regarding the latter, we show that the mobility edge signalling the Anderson-like transition in the Dirac spectrum vanishes as one enters the reconfined phase, as it happens in the standard confined phase. Thermal monopoles, instead, show a peculiar behavior: their density decreases going through reconfinement, at odds with the standard thermal theory; nonetheless, they condense at reconfinement, like at the usual confinement transition. The coincidence of monopole condensation and Dirac mode delocalization, even in a framework different from that of the standard confinement transition, suggests the existence of a strict link between them.

description: As part of the development of the Forest Reference Emissions Level (NERF) of the Republic of Congo, it was organized in selected forest sites (Kabo, Ngombé, Leopolda and Mpoukou - Ogoueé), dendrometric work, to measure the actual diameters and lengths of barrels and logs of felled trees. 

The measurements of the trees were carried out on the so-called "Declared Fût" i.e., the "Gross Fût" and on the "Real Fût" that is, the "Net Fût".

In forest sites developed and certified to the FSC standard (Kabo and Ngombé), the average rate of cask ad waste after felling of trees is around 20%. On the other hand, in developed and not yet certified logging sites to the standards approved by the Republic of Congo, the average rate of cask arse losses after felling of trees is around 30%.

description: In a closed system, it is well known that the time-reversal symmetry can lead to Kramers degeneracy and protect nontrivial topological states such as quantum spin Hall insulator. In this letter we address the issue whether these effects are stable against coupling to environment, provided that both environment and the coupling to environment also respect the time-reversal symmetry. By employing a non-Hermitian Hamiltonian with the Langevin noise term and ultilizing the non-Hermitian linear response theory, we show that the spectral functions for Kramers degenerate states can be split by dissipation, and the backscattering between counter-propagating edge states can be induced by dissipation. The latter leads to the absence of accurate quantization of conductance in the case of quantum spin Hall effect. As an example, we demonstrate this concretely with the Kane-Mele model. Our study could also be extended to interacting topological phases protected by the time-reversal symmetry.

description: In recent years microfabricated microwave cavities have been extremely successful in a wide variety of detector applications. In this article we focus this technology on the challenge of quantum-limited displacement detection of a macroscopic object. We measure the displacement of a nanomechanical beam by capacitively coupling its position to the resonant frequency of a superconducting transmission-line microwave cavity. With our device we realize near state-of-the-art mechanical force sensitivity (3 $\rm{aN/\sqrt{Hz}}$) and thus add to only a handful of techniques able to measure thermomechanical motion at 10's of milliKelvin temperatures. Our measurement imprecision reaches a promising 30 times the expected imprecision at the standard quantum limit, and we quantify our ability to extract measurement backaction from our results as well as elucidate the important steps that will be required to progress towards the full quantum limit with this new detector.

description: Recent work in percolation has led to exact solutions for the site and bond critical thresholds of many new lattices. Here we show how these results can be extended to other classes of graphs, significantly increasing the number and variety of solved problems. Any graph that can be decomposed into a certain arrangement of triangles, which we call self-dual, gives a class of lattices whose percolation thresholds can be found exactly by a recently introduced triangle-triangle transformation. We use this method to generalize Wierman's solution of the bow-tie lattice to yield several new solutions. We also give another example of a self-dual arrangement of triangles that leads to a further class of solvable problems. There are certainly many more such classes.

In the first part we investigate the effect of nuclear parameters on the synthesis of Mo92 and Mo94. Based on recent experimental results, we find that the proton rich winds of the model investigated here can not be the source of solar Mo92 and Mo94. In the second part we investigate the nucleosynthesis from neutron rich bubbles and show that they do not contribute to the overall nucleosynthesis.

description: Exploration is an essential way for children to make sense of the world and reflect on self-identity in the view of constructionism. With materials provided by culture and surroundings, children explore and act in the unknowns in order to understand them. Nowadays, the digital age has created a large variety of technical artifacts that children interact with and provided new environments for them to explore and learn. Existing technologies have been utilized for children’s learning and personal growth. Particularly, artifacts with various levels of anthropomorphism are widely researched in the education domain. On the one end of the spectrum are social robots, which have a higher level of autonomy and more complex underlying mechanisms. They are commonly used as children’s companions and provide social support for learning activities in school or at home. On the other end of the spectrum are animated objects with more abstract shapes and less autonomous behaviors. Many of them are built on the learning theory of constructionism and invented for children's creative activities such as drawing and storytelling. This thesis is particularly interested in using social robots in the domain of art making. Different from the objects with abstract forms in the prior work, the robot examined here has a more anthropomorphic look and animated behaviors. In comparison with skill development and subject learning that are commonly researched for social robots, this thesis aims to stimulate children's exploration and curiosity in art creation. The hypothesis is that children may act differently with more willingness to explore uncertainties in art with the life endowment for the robot. Here an augmented system with a social robot is designed and implemented that engages children in digital art making activities. On a projected floor, children interact with a mobile robot Kuri with movements and explore the underlying mechanisms of robot behaviors. Further, the thesis investigates robot social behaviors displayed with its facial expressions, body movements, sound and light, and designs experiments to evaluate their effects on children’s exploration of uncertainties in the interactive process.

description: In this work, we study the lepton-number-violating processes of $K^\pm$ and $D^\pm$ mesons. Two quasi-degenerate sterile neutrinos are assumed to induce such processes. Different with the case where only one sterile neutrino involves, here, the CP phases of the mixing parameters could give sizable contribution. This, in turn, would affect the absolute values of the mixing parameters determined by the experimental upper limits of the branching fractions. A general function which express the difference of the mixing parameters for two-generation and one-generation is presented. Special cases with specific relations of the parameters are discussed. Besides, we also thoroughly investigate the CP violation effect of such processes. It is shown that generally $\mathcal A_{CP}$ is a function of the sterile neutrino mass.

description: There are 10 generalized Kac-Moody algebras whose denominator identities are completely reflective automorphic products of singular weight on lattices of squarefree level. Under the assumption that the meromorphic vertex operator algebra of central charge 24 and spin-1 algebra $\hat{A}_{p-1,p}^r$ exists we show that four of them can be constructed in a uniform way from bosonic strings moving on suitable target spaces.

description: The nonlinear Hall effect due to Berry curvature dipole (BCD) induces frequency doubling, which was recently observed in time-reversal-invariant materials. Here we report novel electric frequency doubling in the absence of BCD on a surface of the topological insulator Bi2Se3 under zero magnetic field. We observe that the frequency-doubling voltage transverse to the applied ac current shows a threefold rotational symmetry, whereas it forbids BCD. One of the mechanisms compatible with the symmetry is skew scattering, arising from the inherent chirality of the topological surface state. We introduce the Berry curvature triple, a high-order moment of the Berry curvature, to explain skew scattering under the threefold rotational symmetry. Our work paves the way to obtain a giant second-order nonlinear electric effect in high mobility quantum materials, as the skew scattering surpasses other mechanisms in the clean limit.

description: The purpose of this study was to assist the Department of Highways in conducting bridge-painting operations involving removal of existing lead-based paint. Pertinent state and Federal regulations affecting generation of hazardous wastes, limiting environmental pollution and protecting public and worker safety were obtained and reviewed.State highway agendas were surveyed relative to how they conducted maintenance bridge painting involving lead-based. paints and comply with applicable regulations. Information from the painting industry related to sale removal of lead-based paints was also reviewed.  Based upon the reviews of applicable regulations, operations of other state highway agencies and painting industry practices, the best demonstrated available technology to use in removing lead-based paints from bridges was identified. The key technologies incorporated the use of: 1) containment enclosures over the open abrasive blasting, 2) recyclable abrasives and 3) closed material-handling systems to move abrasive-blasting wastes.  The Study Advisory Committee determined that the Best Demonstrated Available Technology would be applied to all bridge maintenance painting operations involving the full removal of lead-based paints. The Committee decided that the Department of Highways would limit painting contractors' work to painting-related activities. The Department employ a consultant to monitor activities related to the generation of hazardous wastes. The consultant would also inspect the contractor's painting work. The Department would also employ a contractor to transport treat and dispose hazardous wastes generated by abrasive blasting.  Three documents were prepared to facilitate this work including: 1) an experimental special provision for bridge maintenance painting, 2) a invitation-to-bid for hazardous waste transport and disposal, and 3) a consultant services contract for environmental monitoring, waste management and inspection of contractor painting operations.

description: Στην παρούσα εργασία προσδιορίστηκαν οι ηθολογικές και οικολογικές προσαρμογές ενός πληθυσμού πλατωνιών Dama dama L., κάτω από συνθήκες έντονης πίεσης και μέτριας ή υψηλής όχλησης. Αντικείμενο μελέτης αποτέλεσε ο ημιφυσικός πληθυσμός που διαβιεί στο κάστρο της πόλης της Μύρινας Λήμνου, κάτω από τις δύσκολες συνθήκες που φυσιολογικά επικρατούν σε ένα νησί. Τα δεδομένα που συλλέχθηκαν την περίοδο 2005-2006, κάλυπταν τη διάρκεια ενός χρόνου και αφορούσαν τόσο στα χαρακτηριστικά και στις συνήθειες του είδους όσο και στον περιβάλλοντα χώρο διαβίωσης. Παρά το βεβαρημένο περιβάλλον, με τα έντονα σημάδια υπερβόσκησης και τις περιορισμένες τροφικές πηγές, τα πλατώνια φαινόταν να έχουν προσαρμοστεί αρκετά καλά στο διαθέσιμο χώρο, χρησιμοποιώντας μέρη με μερική κάλυψη, οριζόντια ή ήρεμη κλίση και με τη μικρότερη δυνατή όχληση. Χαρακτηριστικά του πληθυσμού, όπως η αναλογία φύλου και η δημιουργία κοινωνικών ομάδων ακολουθούσαν το αντίστοιχο πρότυπο των άγριων πληθυσμών. Ωστόσο η ιδιαίτερα υψηλή πυκνότητα του πληθυσμού αναλογικά με τον υπάρχοντα χώρο διαβίωσης έχει επιφέρει ποικιλία επιπτώσεων στην αναπαραγωγική στρατηγική και την επιβίωσή των ζώων και σε συνδυασμό με τα υψηλά επίπεδα της όχλησης, πιθανότατα αποτελεί αναδραστικό παράγοντα στην περαιτέρω αύξηση του πληθυσμού. Η αμοιβαία συνύπαρξη των πλατωνιών με τον άνθρωπο προϋποθέτει τη λήψη μέτρων που θα αποσκοπούν στον έλεγχο του πληθυσμού, τον περιορισμό των ενδεχόμενων ζημιών και την αναβάθμιση του ενδιαιτήματος.
description: In the present study a population of Fallow deer Dama dama L., living on the island of Lemnos, in an area near the island's capital, was surveyed. The aim of the study was to describe the current size and structure of the population, as well as use of habitat and behavioral patterns of adult male and female fallow deer under intensive conditions. The data were gathered during 2005-2006, using animal scan sampling procedures. Despite the heavily grazed environment and the limited food sources, the fallow deer appeared to be well habituated to the present area, using mainly forest patches, with horizontal or medium inclination, distant from human settlements. Sex ratio and sexual segregation followed similar patterns to wild populations. However the high density of the population has caused a variety of consequences to the reproductive strategy and survival, which in combination with the high levels of human disturbance may inhibit tendencies of population increase. Mutual coexistence of fallow deer and humans requires the adoption of specific measures of population control, restriction of damages and habitat improvement.

description: A velocity dispersion has been measured for the luminous globular cluster M31 037 - B327, claimed to be the most massive star cluster in the Local Group and to be a young ``super star cluster'' that has survived to an old age. M31 037 - B327 has a mass comparable to that of M31 G1, but not significantly larger. Although near the upper end for the mass distribution of globular clusters, it is not an unprecedented extraordinary object.

description: In terms of the demans of the contemporary competitive world, neither the education system in assam nor that of theentire nation is adequate. While a portion of our society is moving towards a postmodern society, Roughly 30% ofindividuals are still illiterate and falling behind. Due to this unequal distribution of education, our nation is impactpolitically, socially, economically. Our current education system is dominated by the outdated theoretical education system.Mere theoretical knowledge is insufficient to function in the real world today. In order for pupils to compete in the moderncomplicated socio economic sector, the current educational system, particularly that operated by the state government, wasunable to provide them with the necessary information.lack of teaching aids, a shortage of practically qualified teachers, afailure to cover some critical subjects and a lack of adequate educational infrastructure prevents students from developingthe necessary human capital for our economy, which ultimately contibutes to the problem of poverty and unemployment.Therefore, to keep up with the modern technologically advanced, and competitive world, our educational system needs to bemodified somewhat.The problems that now exist should be recognised and appropriate solutions should then beimplemented.
Stress Evaluation of Welded Steel Bridges on Coal-Haul Routes

description: This report describes the procedure developed and being employed to determine and assess live-load stresses in structural members of welded steel bridges on extended· weight coal haul routes. Those bridges are routinely subjected to loads from coal trucks in excess of those permitted on other routes. Those elevated loads may result in high stresses in bridge members. Of principal concern are certain weld details on steel bridges that are susceptible to fatigue cracking when subject to high live-load stresses. Seventeen welded steel bridges on extended-weight coal haul routes have been identified for investigation under this study.  The study test procedure consists of 1) a review of coal-haul data and plans to identify lanes of a bridge subject to greatest coal-truck loading, 2) identification of weld details of interest for analysis on portions of the bridge superstructure subject to high live-load stresses, 3) field application of strain gages to measure live-load stresses at locations of interest on a bridge, 4) continuous monitoring of live stresses from routine traffic for an extended period and 5) data retrieval and reduction and fatigue analysis.  Fatigue analysis is based on the number of stress cycles measured during the field test and the equivalent resolved live-load stress. That is compared to the 1992 AASHTO fatigue performance data for applicable structural details (e.g. welded connections). An exemplary use of the study test procedure is given for the KY 15 bridge over the North Fork of the Kentucky River and KY SO in Perry Co. This report describes the test locations, test procedures and results of the derived test data.  The field tests will indicate the level of live-load stresses to which the bridges are exposed. Additionally, the fatigue analyses may indicate whether welded steel bridges on extended-weight coal haul routes are susceptible to fatigue damage.
On non-homogeneous quasi-linear PDEs involving the p-Laplacian and the critical sobolev exponent
Creators: name: Yuan, Chaogui
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is devoted to the study of some quasi-linear PDEs involving the p-Laplacian. This type of problem represents a model case for the general quasi-linear elliptic equations. These problems arise from the Euler-Lagrange equations associated to various geometric problems and from topics like Non-Newtonian Fluids, Air Dynamics, Nonlinear Biological Population, Reaction-Diffusion Problems etc. The difficulties in- these problems come either from the lack of compactness of the approximate solutions or from the lack of symmetry in the corresponding energy functionals. The thesis has basically two parts. The first part is in Chapter 3, where we consider a problem related to Yamabe's prescribed curvature conjecture in Riemannian Geometry. This problem is critical in the sense that it involves the critical exponent in the Sobolev embedding. In particular, we show the existence of sign changing solutions by using the duality methods introduced by N. Ghoussoub. In the second part of the thesis, chapters 4 - 7, we consider the associated nonhomogeneous problems which arise from either a linear second member or from nonhomogeneous Dirichlet boundary conditions. Because of the lack of symmetry, the traditional equivariant variational principles do not apply here. To overcome those difficulties, we extend and use Bolle's method as well as Ekeland-Ghoussoub's virtual critical point theory to a Banach space setting.
