description: We propose a two-population lattice Boltzmann model on standard lattices for the simulation of compressible flows. The model is fully on-lattice and uses the single relaxation time Bhatnagar-Gross-Krook kinetic equations along with appropriate correction terms to recover the Navier-Stokes-Fourier equations. The accuracy and performance of the model are analyzed through simulations of compressible benchmark cases including Sod shock tube, sound generation in shock-vortex interaction and compressible decaying turbulence in a box with eddy shocklets. It is demonstrated that the present model provides an accurate representation of compressible flows, even in the presence of turbulence and shock waves.

Onthe base of a uniform semiclassical theory we derive the fidelity decay which displays a quite complexbehaviour, from Gaussian to power law decay $t^{-α}$ with $1 \le α\le 2$. Semiclassical estimates are given for the time scales separating the different decaying regions and numerical results are presented which confirm our theoretical predictions.

description: The main purpose of this dissertation is to review and evaluate the fishery production of coastal lakes in the prefectures of Xanthi, Kavala, and Rodopi in Northern Greece, for the time span between 1972 and 2014. Data was taken from local fishery authorities and cooperatives. For each individual lake there was a presentation of its entire cumulative production by year, in timeline graphs. The fishery composition was presented for the entire time span, and also divided in 5 year periods to show changes in the distribution of species. Finally, ARIMA, moving average and trend analysis models were utilized to predict the course of fishery production for the next 3 years. This analysis of yearly fluctuations, combined with bibliographical resources led us to evaluate the potential of each lake, their sensitivity to external factors and the way the affect fishery production.

description: A detailed investigation of the first order antiferromagnetic insulator (AFI) to ferromagnetic metal (FMM) transition in $Nd{_{0.5}}Sr{_{0.5}}MnO{_{3}}$ is carried out by resistivity and magnetization measurements. These studies reveal several anomalous features of thermomagnetic irreversibility across the first order transition. We show that these anomalous features can not be explained in terms of supercooling effect alone and H-T diagram based on isothermal MH or RH measurement alone do not reflect true nature of the first order transition in this compound. Our investigations reveal glass-like arrest of kinetics at low temperature which plays a dominant role in the anomalous thermomagnetic irreversibility observed in this system. The interplay between kinetic arrest and supercooling is investigated by following novel paths in the H-T space. It is shown that coexisting FMM and AFI phases can be tuned in a number of ways at low temperature. These measurements also show that kinetic arrest temperature and supercooling temperature are anti-correlated i.e. regions which are arrested at low temperature have higher supercooling temperature and vice versa.

Differential polarization of Hβ in γ CAS
Creators: name: Jiang, Yiman
Publisher: name: University of British Columbia
Year: 2008

description: High resolution ( 0.15 Å/pixel ) spectropolarimetry across the Hβ emission line of the Be star γ Cas is presented. The differential polarization and polarization angle vary both in profile and depth. It was found that the polarization profile fits the relation PL, = (Iunderlying / Itotal)Pc, instead of the generally accepted PL = PC / Iemmission (Coyne 1975). Assuming the absolute polarization in the adjoining continuum is constant, the polarization profile is used to determine Teff, geff, and v sin i for the underlying star by fitting the Hubeny (1988) atmosphere model. The Be star model developed by Poeckert and Marlborough (1978a) for γ Cas is used as a basis to explain our polarization observations. We have made two types of modifications to the model: the first being to revise the intrinsic properties of the underlying star; the other is to make more accurate treatment of the radiation transfer equation in the disk. A search of the parameter space was made to find the best fit. We find an adequate fit to the emission line profile, but only a poor fit to the polarization profile from Poeckert and Marlborough model.

description: Crystallographic symmetries enforcing band touchings (BTs) in the Brillouin zone (BZ) have been utilized to classify and predict the topological semimetals. Though the early proposed topological semimetals contain isolated nodal points in the BZ, the proposed nodal line semimetals later could host various structures of several nodal lines/loops: nodal chains, nodal nets or Hopf-links, etc. In this work, using compatibility relations, we first list all possible high symmetry lines (HSLs) that can be nodal lines itself, high symmetry planes (HSPLs) that can host nodal loops, high symmetry planes (HSPLs) that are nodal surfaces for all 230 SGs, with spin-orbit coupling and time-reversal symmetry considered or not. We then show how to diagnose a nodal loop from the band crossing in an HSL, or nodal line/surface from irreducible representation (irrep) of an high-symmetry point (HSP), while the rest cases correspond to nodal points. Among our results, those essential cases, for which the nodal points/lines/loops/surfaces must exist, are highlighted since they are promising for the realizations of (nearly) ideal nodal point/line/loop/surface semimetals, as well as systems with flexible tunability owning fixed structure of topological nodal points/lines/loops/surfaces. Based on our results, SGs allowing Hopf-link structure with one straight nodal line threading a nodal loop, or two nesting nodal loops lying in two respective high symmetry planes, are highlighted, with the predicted materials being B$_5$Pb$_2$IO$_9$ in SG 34 and SrAl$_2$Au$_3$ in SG 62, respectively. Our exhaustive results could serve as a useful guide for efficiently predicting and designing materials or artificial systems owning exotic geometric nodal structures of energy bands simply based on structure symmetries.

The inhomogeneous gap structures are observed above and below Tc on Gd-Bi2201. Increasing the out-of-plane disorder which is controlled by mismatch of the ionic radius between Sr and Ln results in the enhancement of pseudogap region with suppressed coherence peaks in the conductance spectrum, making the gap average larger and the gap distribution wider. The degree of electronic inhomogeneity measured by the distribution width of the gap amplitude is shown to have a correlation with Tc in optimally doped Bi2201 and Bi2212.

Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: Recently, gradient index cavities, or so-called transformation cavities, designed by conformal transformation optics have been studied to support resonant modes with both high Q-factors and emission directionality. We propose a new design method for transformation cavities to realize a narrower width of the refractive index profile, a great advantage in experimental implementations, without losing the benefits of conformal mapping. We study the resonant modes with both high Q-factor and directional emission in the newly designed transformation cavities, where the refractive index profile is 50 percent narrower than in previously proposed transformation cavities. By varying a system parameter with a fixed maximal value of the refractive index profile inside the cavity, the width of the refractive index profile narrows, the Q-factors become higher, and the near and far field patterns maintain their properties, namely conformal whispering gallery modes and bidirectional emission, respectively.

description: Spontaneous chiral symmetry breaking in QCD with massless quarks at infinite volume can be seen in a finite box by studying, for instance, the dependence of the chiral condensate from the volume and the quark mass. We perform a feasibility study of this program by computing the quark condensate on the lattice in the quenched approximation of QCD at small quark masses. We carry out simulations in various topological sectors of the theory at several volumes, quark masses and lattice spacings by employing fermions with an exact chiral symmetry, and we focus on observables which are infrared stable and free from mass-dependent ultraviolet divergences. The numerical calculation is carried out with an exact variance-reduction technique, which is designed to be particularly efficient when spontaneous symmetry breaking is at work in generating a few very small low-lying eigenvalues of the Dirac operator. The finite-size scaling behaviour of the condensate in the topological sectors considered agrees, within our statistical accuracy, with the expectations of the chiral effective theory. Close to the chiral limit we observe a detailed agreement with the first Leutwyler-Smilga sum rule. By comparing the mass, the volume and the topology dependence of our results with the predictions of the chiral effective theory, we extract the corresponding low-energy constant.

Aviation emissions transport and long-term characterization of ultrafine particles in and around airports. Introduction of the project AVIATOR
Creators: name: Archilla, Victor
Publisher: name: Karlsruhe
Year: 2019

description: Emissions from aircraft have adverse effects on air quality in and around airports and can contribute to public health concerns within neighboring communities. Routine air quality monitoring at airports generally focus on regulated air pollutants. However, recent work has shown that aircraft exhaust emissions are a major source of UFP (<0.1μm) in and around airports. This is creating significant concern as the health and environmental impact of UFP is currently insufficiently understood. AVIATOR (Assessing aViation emission Impact on local Air quality at airports: TOwards Regulation) is a European proposal which will adopt a multi-level measurement, modelling and assessment approach to develop an improved description and quantification of the relevant aircraft engine emissions, and their impact on air quality under different climatic conditions. Engine generated particulate matter (PM) and gaseous emissions in test-cell and on-wing from an in-service aircraft will be measured to determine pollutant plume evolution from the engine and APU exhaust. This will provide an enhanced understanding of emitted pollutants, and the scalability between the regulatory test-cell and real-world environments. Specific attention will be focused on non-volatile PM and volatile PM (down to <10 nm), and volatile PM gaseous precursors. AVIATOR will develop and deploy across multiple airports, a proof-of-concept low-cost sensor network for the monitoring of ultra-fine particles (UFP), total PM and gaseous species such as NOx and SOx, across airport and surrounding communities. Transport of emissions from aircraft engines and APU will be monitored in this complex environment through high-fidelity and sensor measurements. Measurement campaigns will be complemented by high-fidelity modelling of aircraft exhaust dynamics, and microphysical and chemical processes within the plume. Inter-connected process models will be applied and new validated parameterisations of the critical processes determined. AVIATOR will develop improved guidance on measuring and modelling the impact of aircraft emissions with specific reference to UFP.

description: The process of writing and verifying planning problems is a process that can be quite complex and demands a lot of resources in order to provide or verify a satisfying solution. For that reason, specialized software have been create with the purpose of easing the whole process, either for veterans in the field or amateurs alike. The variety of the aforementioned tools, the complexity of the problems at hand and the differences observed between the suggested solutions make clear that there is need for further research concerning the ease of the process of solving planning problems. This thesis focuses on the creation of a new system that verifies proposed solutions for planning problems through the development of specialized web services as well as through the extension of existing means of visualizing planning problems in order to hetter utilize the newly created functions. The new services try to validate any solution that is offered by an automated planner that got input from a user. After finishing their task, they provide various informational pieces concerning the solved problem and its validity. Moreover, these services are tightly integrated into VLEPpO, a platform for designing and validating planning problems.

description: This paper concerns the analysis of Late Bronze Age charred plant remains from Archondiko Giannitson, a bronze age tell settlement, in order to investigate the different aspects related to the use of plants by humans: the choice of species, their possible uses, agricultural practices, processing methods and storage. The study of the archaeobotanical remains indicates that they come from stored crops, mostly cereals, and less pulses and non-cultivated species. The analysis provides evidence for the possible coexistence of intensive husbandry practices with extensive cultivation of wheat, the diversification of production, and the introduction of new cultivated species. This new dataset contributes to the ongoing discussion about the economic organization of Late Bronze Age communities in the broader area of Macedonia.
Unmasking the Origin of Kinks in the Photoemission Spectra of Cuprate Superconductors

description: The origin of a ubiquitous bosonic coupling feature in the photoemission spectra of high-Tc cuprates, an energy-momentum dispersion 'kink' observed at ~70 meV binding energy, remains a two-decade-old mystery. Understanding this phenomenon requires an accurate description of the coupling between the electron and some collective modes. We report here ab initio calculations based on GW perturbation theory and show that correlation-enhanced electron-phonon interaction in cuprates gives rise to the strong kinks, which not only explains quantitatively the observations but provides new understanding of experiments. Our results reveal it is the electron density-of-states being the predominant factor in determining the doping-dependence of the kink size, manifesting the multi-band nature of the cuprates, as opposed to the prevalent belief of it being a measure of the mode-coupling strength.

description: It is usual in introductory courses of mechanics to develop the work and energy formalism from Newton's laws. On the other hand, literature analyzes the way in which forces transform under a change of reference frame. Notwithstanding, no analogous study is done for the way in which work and energy transform under those changes of reference frames. We analyze the behavior of energy and work under such transformations and show explicitly the expected invariance of the formalism under Galilean transformations for one particle and a system of particles. The case of non inertial systems is also analyzed and the fictitious works are characterized. In particular, we show that the total fictitious work in the center of mass system vanishes even if the center of mass defines a non inertial frame. Finally, some subtleties that arise from the formalism are illustrated by examples.

A new low-beta regime for unstable proton firehose modes in bi-Kappa distributed plasmas

description: In the solar wind plasma an excess of kinetic temperature along the background magnetic field stimulates proton firehose modes to grow if the parallel plasma beta parameter is sufficiently high, i.e., $β_{p \parallel}\gtrsim 1$. This instability can prevent the expansion-driven anisotropy from increasing indefinitely, and explain the observations. Moreover, such kinetic instabilities are expected to be even more effective in the presence of suprathermal Kappa-distributed populations, which are ubiquitous in the solar wind, are less affected by collisions than the core population, but contribute with an additional free energy. In this work we use both linear and extended quasi-linear (QL) frameworks to characterize the unstable periodic proton firehose modes (propagating parallel to the magnetic field) under the influence of suprathermal protons. Linear theory predicts a systematic stimulation of the instability, suprathermals amplifying the growth rates and decreasing the instability thresholds to lower anisotropies and lower plasma betas ($β_{p \parallel}<1$). In perfect agreement with these results, the QL approach reveals a significant enhancement of the resulting electromagnetic fluctuations up to the saturation with a stronger back reaction on protons, leading also to a faster and more efficient relaxation of the temperature anisotropy.

description: We present a series of cosmological N-body simulations which make use of the hydrodynamic approach to the evolution of structures (Dominguez 2000). This approach addresses explicitly the existence of a finite spatial resolution and the dynamical effect of subresolution degrees of freedom. We adapt this method to cosmological simulations of the standard LCDM structure formation scenario and study the effects induced at redshift z=0 by this novel approach on the large-scale clustering patterns as well as (individual) dark matter halos. Comparing these simulations to usual N-body simulations, we find that (i) the new (hydrodynamic) model entails a proliferation of low--mass halos, and (ii) dark matter halos have a higher degree of rotational support. These results agree with the theoretical expectation about the qualitative behaviour of the "correction terms" introduced by the hydrodynamic approach: these terms act as a drain of inflow kinetic energy and a source of vorticity by the small-scale tidal torques and shear stresses.

Εξετάσαμε την έννοια της ιατρικής ευθύνης και τα είδη της, το ιατρικό σφάλμα και την υποχρέωση ενημέρωσης και συναίνεσης του ασθενούς ως γενεσιουργούς λόγους της ιατρικής ευθύνης καθώς και την υποχρέωση του ιατρού ή του φορέα παροχής υπηρεσιών υγείας προς αποζημίωση στα πλαίσια του ΑΚ. Στη συνέχεια παρουσιάσαμε αναλυτικά τη λειτουργία της ασφάλισης στον τομέα της ιατρικής ευθύνης, ξεκινώντας από μια ιστορική επισκόπηση και εξετάζοντας εν συνεχεία τα επιμέρους χαρακτηριστικά της, όπως τη νομική της φύση, τον μη υποχρεωτικό της χαρακτήρα στα πλαίσια του άρθρου 25 ΑσφΝ, την διαδικασία κατάρτισης και το περιεχόμενο της σύμβασης. Ιδιαίτερη έμφαση δόθηκε στην εννοιολογική και χρονική διαφορά μεταξύ της επέλευσης της ασφαλιστικής περίπτωσης και της πραγματοποίησης του κινδύνου στην ασφάλιση ιατρικής ευθύνης και στις συνέπειες που επιφέρει η διαφορά αυτή ως προς τη διάρκεια κάλυψης και την έκταση της ευθύνης του ασφαλιστή. Τέλος αναφερθήκαμε στις δυο ρήτρες της διεθνούς ασφαλιστικής πρακτικής(ρήτρα occurrence και ρήτρα claims made) και ασχοληθήκαμε επιπλέον με την αξίωση ελευθερώσεως και νομικής προστασίας του λήπτη- ασφαλισμένου στα πλαίσια του άρθρου 25ΑσφΝ, τα δικαιώματα των τρίτων ζημιωθέντων και το ζήτημα της συμμετοχής του ασφαλιστή στην αστική δίκη.
description: The topic of this dissertation is insurance of medical liability in terms of malpractice, as special type of civil liability insurance. We presented the concept of medical liability and its types , the medical error and the obligation for informed patient consent, as the underlying reasons for medical malpractice and finally the obligation for compensation, according to the civil code. Subsequently, we delved into the topic of insurance for medical malpractice, starting with a historical overview of the particular insurance product, the not compulsory character but the general or optional character of the professional malpractice insurance according to insurance law (article 25), the legal nature and the drafting procedure, as well as the contents of the contract . We emphasized the conceptual and temporal divergence between “occurrence” and “claims made” and the consequences on the duration of coverage and the liability of the insurer. At this point the two clauses of international insurance practice are presented and interpreted, namely the clauses of “occurrence” and “claims made”. Finally we focused on the right for debt transfer and legal protection of the insured as stated in insurance law (article 25), the rights of third parties and the practice of calling the insurer to participate in the civil trial .

description: TeV-scale extra dimensions may play an important role in electroweak or supersymmetry breaking. We examine the phenomenology of such dimensions, compactified on a sphere $S^n$, $n \geq 2$, and show that they possess distinct features and signatures. For example, unlike flat toroidal manifolds, spheres do not trivially allow fermion massless modes. Acceptable phenomenology then generically leads to "non-universal" extra dimensions with "pole-localized" 4-$d$ fermions; the bosonic fields can be in the bulk. Due to spherical symmetry, some Kaluza-Klein (KK) modes of bulk gauge fields are either stable or extremely long-lived, depending on the graviton KK spectrum. Using precision electroweak data, we constrain the lightest gauge field KK modes to lie above $\simeq 4$ TeV. We show that some of these KK resonances are within the reach of the LHC in several different production channels. The models we study can be uniquely identified by their collider signatures.

description: WALOP (Wide-Area Linear Optical Polarimeter)-South, to be mounted on the 1m SAAO telescope in South Africa, is first of the two WALOP instruments currently under development for carrying out the PASIPHAE survey. Scheduled for commissioning in the year 2021, the WALOP instruments will be used to measure the linear polarization of around $10^{6}$ stars in the SDSS-r broadband with $0.1~\%$ polarimetric accuracy, covering 4000 square degrees in the Galactic polar regions. The combined capabilities of one-shot linear polarimetry, high polarimetric accuracy ($< 0.1~\%$) and polarimetric sensitivity ($< 0.05~\%$), and a large field of view (FOV) of $35\times35~arcminutes$ make WALOP-South a unique astronomical instrument. In a single exposure, it is designed to measure the Stokes parameters $I$, $q$ and $u$ in the SDSS-r broadband and narrowband filters between $500-700~nm$. During each measurement, four images of the full field corresponding to the polarization angles of $0^{\circ}$, $45^{\circ}$, $90^{\circ}$ and $135^{\circ}$ will be imaged on four detectors and carrying out differential photometry on these images will yield the Stokes parameters. Major challenges in designing WALOP-South instrument include- (a) in the optical design, correcting for the spectral dispersion introduced by large split angle Wollaston Prisms used as polarization analyzers as well as aberrations from the wide field, and (b) making an optomechanical design adherent to the tolerances required to obtain good imaging and polarimetric performance under all temperature conditions as well as telescope pointing positions. We present the optical and optomechanical design for WALOP-South which overcomes these challenges.

Risk prediction models for binary response variables for the coronary bypass operation
Creators: name: Zhang, Hongbin
Publisher: name: University of British Columbia
Year: 2008

description: The ability to predict 30 day operative mortality and complications following coronary artery bypass surgery in the individual patient has important implications clinically and for the design of clinical trials. This thesis focuses on setting up risk stratification algorithms. Utilizing the binary feature of the response variables, logistic regression analyses and classification trees (recursive partitioning) were used with the variables identified by the Health Data Research Institute in Portland, Oregon. The data set contains records for 18171 patients who had coronary artery bypass surgery in one of several hospitals between 1968 to 1991. Statistical models are setup, one from each method, for six outcome variables of the surgery: 30 day operative mortality, renal shutdown complication, central nervous system complication, pneumothorax complication, myocardial infarction complication and low output syndrome. The risk groups vary across different outcomes. The history of cardiac surgery has strong association with operative mortality and patients who suffer from a central nervous system disease tend to have higher risks for all the outcomes. Further study is necessary to consider the differences among hospitals and to divide the population according to the type of previous cardiac surgery.

description: The spectrum of the low-redshift QSO PG0953+415 shows two strong, intervening O VI absorption systems. To study the nature of these absorbers, we have used the Gemini Multiobject Spectrograph to conduct a deep spectroscopic galaxy redshift survey in the 5' x 5' field centered on the QSO. This survey is fully complete for r' < 19.7 and is 73% complete for r' < 21.0. We find three galaxies at the redshift of the higher-z O VI system (z = 0.14232) including a galaxy at projected distance rho = 155 kpc. We find no galaxies in the Gemini field at the redshift of the lower-z O VI absorber (z = 0.06807), which indicates that the nearest galaxy is more than 195 kpc away or has L < 0.04 L*. Previous shallower surveys covering a larger field have shown that the z = 0.06807 O VI absorber is affiliated with a group/filament of galaxies, but the nearest known galaxy has rho = 736 kpc. The z = 0.06807 absorber is notable for several reasons. The absorption profiles reveal simple kinematics indicative of quiescent material. The H I line widths and good alignment of the H I and metal lines favor photoionization and, moreover, the column density ratios imply a high metallicity: [M/H] = -0.3 +/- 0.12. The z = 0.14232 O VI system is more complex and less constrained but also indicates a relatively high metallicity. Using galaxy redshifts from SDSS, we show that both of the PG0953+415 O VI absorbers are located in large-scale filaments of the cosmic web. Evidently, some regions of the web filaments are highly metal enriched. We discuss the origin of the high-metallicity gas and suggest that the enrichment might have occurred long ago (at high z).

Origin theories for the eccentricities of extrasolar planets

description: Half the known extrasolar planets have orbital eccentricities in excess of 0.3. Such large eccentricities are surprising as it is thought that planets form in a protoplanetary disk on nearly circular orbits much like the current states of the solar system planets. Possible explanations for the large planetary eccentricities include the perturbations that accompany planet-planet scattering, the tidal interaction between the gas disk and the planets, Kozai's secular eccentricity cycles, the eccentricity excitation during planetary pair migration in mean motion resonance, the perturbations by stellar encounters, stellar-like relaxation that occurs if planets formed through gravitational instability, and the relative acceleration by the stellar jet system of the host star with respect to the companion. In this chapter, we comment on the relevance and characteristics of the various eccentricity origin theories.

description: A high-resolution (sigma_instr. = 1.5 MeV) search for narrow states (Gamma < 10 MeV) with masses of M_x approx 1500-1850 MeV in ep -> e'K^+ X, e'K^- X and e' pi^+ X electroproduction at small angles and low Q^2 was performed. These states would be candidate partner states of the reported Theta^+(1540) pentaquark. No statistically significant signal was observed in any of the channels at 90% C.L. Upper limits on forward production were determined to be between 0.7% and 4.2% of the Lambda(1520) production cross section, depending on the channel and the assumed mass and width of the state.

description: We use the data-driven method, The Cannon, to bring 21,000 stars from the ARGOS bulge survey, including 10,000 red clump stars, onto the parameter and abundance scales of the cross-Galactic survey, APOGEE, obtaining rms precisions of 0.10 dex, 0.07 dex, 74 K, and 0.18 dex for [Fe/H], [Mg/Fe], Teff, and log(g), respectively. The re-calibrated ARGOS survey - which we refer to as the A2A survey - is combined with the APOGEE survey to investigate the abundance structure of the Galactic bulge. We find X-shaped [Fe/H] and [Mg/Fe] distributions in the bulge that are more pinched than the bulge density, a signature of its disk origin. The mean abundance along the major axis of the bar varies such that the stars are more [Fe/H]-poor and [Mg/Fe]-rich near the Galactic center than in the long bar/outer bulge region. The vertical [Fe/H] and [Mg/Fe] gradients vary between the inner bulge and long bar with the inner bulge showing a flattening near the plane that is absent in the long bar. The [Fe/H]-[Mg/Fe] distribution shows two main maxima, an ``[Fe/H]-poor [Mg/Fe]- rich'' maximum and an ``[Fe/H]-rich [Mg/Fe]-poor'' maximum, that vary in strength with position in the bulge. In particular, the outer long bar close to the Galactic plane is dominated by super-solar [Fe/H], [Mg/Fe]-normal stars. Stars composing the [Fe/H]-rich maximum show little kinematic dependence on [Fe/H], but for lower [Fe/H] the rotation and dispersion of the bulge increase slowly. Stars with [Fe/H]
