description: Knowing the site of gamma-ray emission in AGN jets will do much for our understanding of the physics of the source. In particular, if the emission region is close to the black hole then absorption of gamma-rays with photons from the broad-line region could become significant. Such absorption is predicted to produce two specific spectral breaks in the gamma-ray spectra of Flat Spectrum Radio Quasars (FSRQs). We test this hypothesis using 3 years of Fermi observations of nine bright FSRQs. A simple power law fit to the spectrum of each source can be significantly improved by introducing a break, but the break energies are inconsistent with those predicted by the double-absorber model. In some cases the fit can be further improved by a log-parabola. In addition, by dividing the data from each source into two equal epochs we find that the best description of an object's spectrum often varies between a log-parabola and a broken power law.

Modelling the dynamics and control of aedes aegypti populations at fine spatial scales
Creators: name: McCormack, Clare
Publisher: name: Imperial College London
Year: 2018

description: Novel vector control measures such as the release of Wolbachia-infected Aedes aegypti offer a promising new pathway for dengue control. However, to realistically model the likely impact of these measures, improved mathematical models of Aedes aegypti population dynamics are needed, with the final goal being spatially explicit models of Aedes aegypti population dynamics, calibrated against high quality entomological data. Here we begin to address the challenge of developing such models by (i) examining the role of spatial structure in shaping the dynamics of Aedes aegypti populations at fine spatial scales and (ii) using advanced inferential methods to fit a dynamical model of Aedes aegypti population dynamics to entomological field data, while allowing for the highly variable nature of mosquito trapping data. We explore the effects of larval breeding habitat fragmentation on fine-scale Aedes aegypti population dynamics for a variety of different landscapes, examining how features of the underlying landscape and the dispersal behaviour of the mosquito affect the dynamics observed. In addition, by modelling the same population at different levels of spatial granularity, we investigate the appropriate level of spatial granularity for models to adopt to represent the fine-scale dynamics of Aedes aegypti populations. We examine the results of a small-scale field trial testing the use of Wolbachia as a tool for Aedes aegypti population suppression in Singapore by calibrating a stochastic model of Aedes aegypti population dynamics against the detailed entomological data collected during the trial. We model both the underlying population dynamics and the trapping process, thereby accounting for variability in mosquito trapping data when estimating the impact of the trial on local Aedes aegypti populations. Thus, the work presented in this thesis represents an important step forward in the challenge of developing models needed to realistically assess the likely impact of novel vector control measures.

description: (Z)-2-(2-(4-(Dihexylamino)-2-methylbenzylidene)-1,1-dioxidobenzo[b]thiophen-3(2H)ylidene)malononitrile (C.I.Disperse Blue 354) and (E)-N-(2-((2-bromo-6-cyano-4-nitrophenyl)diazenyl)-5-(diethylamino)phenyl)propionamide (C.I.Disperse Blue 183) are investigated for nonlinear optical (NLO) properties using Density Functional Theory (DFT) and Z-scan technique. The Z-scan results suggest that both the dyes possess considerably large NLO properties. C.I.Disperse Blue 183 showed major mean first hyperpolarizability (β0) values. B3LYP/6311++G(d,p) performs better compared to other functionals for computing NLO properties of the dyes. Solvent environment contribute an influential role for NLO properties of the dyes as NLO characteristics of dyes increases from non-polar to polar solvents.

description: Extending a previously developed two-phase equation of state, we simulate head-on relativistic lead-lead collisions with fluid dynamics, augmented with a finite-range term, and study the effects of the phase structure on the evolution of the baryon density. For collision energies that bring the bulk of the system into the mechanically unstable spinodal region of the phase diagram, the density irregularities are being amplified significantly. The resulting density clumping may be exploited as a signal of the phase transition, possibly through an enhanced production of composite particles.

Our bounds improve on earlier results of de Launey and Levin (2010) and, for certain congruence classes of n mod 4, those of Koukouvinos, Mitrouli and Seberry (2000). In an Appendix we give a new proof, using Jacobi's determinant identity, of a result of Szöllősi (2010) on minors of Hadamard matrices.

description: The transition from the microscopic Heisenberg model to the macroscopic elastic theory is carried out for the chiral magnetics of MnSi-type with the B20 crystal structure. Both exchange and Dzyaloshinskii-Moriya (DM) interactions are taken into account for the first, second, and third magnetic neighbors. The particular components of the DM vectors of bonds are found, which are responsible for (i) the global magnetic twist and (ii) the canting between four different spin sublattices. A possible mechanism for effective reinforcement of the global magnetic twist is suggested: it is demonstrated that the components of the DM vectors normal to corresponding interatomic bonds become very important for the twisting power. The Ruderman-Kittel-Kasuya-Yosida (RKKY) theory is used for model calculation of exchange parameters. It is found that just the interplay between the exchange parameters of several magnetic shells rather than the signs of DM vectors can be responsible for the concentration-induced reverse of the magnetic chirality recently observed in the Mn_(1-x)Fe_xGe crystals.

If $c_{0} \in \mathbb{R}$ is such that $g(c_0)$ equals the average of $f$ and $g'(c_0)\neq0$, under very mild assumptions on $ω$ there exists a quasi-periodic solution close to $c_0$. We show that such a solution depends analytically on $\varepsilon$ in a domain of the complex plane tangent more than quadratically to the imaginary axis at the origin.

description: Esta pesquisa tem como objetivo caracterizar praxeologias didáticas e matemáticas da abordagem do conteúdo Geometria dos Fractais em livros didáticos do Ensino Médio. Diante do conhecimento da inclusão da Geometria Fractal nas Diretrizes Curriculares de Matemática do Estado do Paraná (DCE) desde 2008, para alcançar o objetigo geral da pesquisa, propomos-nos a analisar quatro coleções de livros didáticos aprovadas pelo Plano Nacional do Livro Didático (PNLD) de 2018, e que foram as mais adotadas entre as 5 maiores cidades, em termos de habitantes, deste estado. A análise dos dados produzidos foi realizada sob o ponto de vista das organizações praxeológicas, sendo nosso referencial teórico-metodológico a Teoria Antropológica do Didático, que oportunizou investigar escolhas matemáticas e didáticas dos autores das coleções. Diante das análises, podemos apontar que o conteúdo Geometria dos Fractais se faz presente, seja de modo teórico ou durante os exercícios, em 4 dos 16 livros didáticos analisados, de modo articulado com outros conteúdos matemáticos como, por exemplo, Números e Álgebra. Desta forma, observamos que o fato de o assunto Geometria dos Fractais não estar contemplado na Base Nacional Comum Curricular (BNCC) não impede que ele seja trabalhado em sala de aula, uma vez que promove a articulação com outras unidades temáticas indicadas no referido documento. Com relação aos Tipos de Tarefas encontrados, apresentam-se, assim como sugerido nas DCE (PARANÁ, 2008), mediante explorações dos fractais como o floco de neve e a curva de Koch; o triângulo e o tapete de Sierpinski. Porém, de maneira geral, predominou uma proposta de ensino para esse tema como meio para o ensino de outros conteúdos.

description: In this paper we continue the investigation of partition functions of critical systems on a rectangle initiated in [R. Bondesan et al, Nucl.Phys.B862:553-575,2012]. Here we develop a general formalism of rectangle boundary states using conformal field theory, adapted to describe geometries supporting different boundary conditions. We discuss the computation of rectangular amplitudes and their modular properties, presenting explicit results for the case of free theories. In a second part of the paper we focus on applications to loop models, discussing in details lattice discretizations using both numerical and analytical calculations. These results allow to interpret geometrically conformal blocks, and as an application we derive new probability formulas for self-avoiding walks.

Nuclear quadrupole interactions of 111In/Cd solute atoms in a series of rare-earth palladium alloys

description: Nuclear quadrupole interactions were measured at 111In/Cd probe atoms in rare-earth palladium phases RPd3 having the L12 structure using the technique of perturbed angular correlation of gamma rays (PAC). Measurements were made for pairs of samples having compositions of the Pd-poorer and Pd-rich boundaries of the RPd3 phase fields, typically 75 and 78 at.% Pd. Two signals were detected in most phases, corresponding to probe atoms on cubic R- and non-cubic Pd-sublattices. Site preferences of parent In-probe atoms were characterized by site-fractions of probes on the R- and Pd-sublattices. For all Pd-rich samples, probes exclusively occupied the R-sublattice, consistent with a heuristic rule that solute atoms tend to occupy the sublattice of an element in which there is a deficiency. For Pd-poorer alloys with R= Tb, Er, Yb, Lu, Y and Sc, probes exclusively occupied the Pd-sublattice. For Pd-poorer alloys with R= Ce, Pr, Nd, Sm and Eu, probes occupied both sublattices, with site fractions varying as a function of temperature. In contrast, probes only occupied the R-sublattice in Pd-poorer LaPd3. Jump frequencies on the Pd-sublattice of daughter Cd-probes were determined from nuclear relaxation caused by fluctuating electric field gradients. Activation enthalpies for diffusional jumps were determined from temperature dependences and found to increase linearly as the lattice parameter decreases along the series Pr, Nd, Eu and Sm. Jump frequencies are believed to have been even higher in CePd3 than in PrPd3, but were too low to be detectable in Tb, Er, Yb, Lu, Y and Sc palladides. A correlation between site preferences and jump frequencies is noted and discussed. This paper provides a complete account of measurements of jump frequencies of Cd-probe atoms and comparisons with similar measurements made on other series of L12 phases.

High yields, short reaction time, easy workup, inexpensive, and reusability of the catalyst are advantages of this method. All structures were elucidated by spectral and elemental analyses. Structures of 6a–c were further proved by alternative synthesis of 6a.
Electroweak phase transition and Higgs boson couplings in the model based on supersymmetric strong dynamics

description: We discuss a strongly-coupled extended Higgs sector with the 126 GeV Higgs boson, which is a low-energy effective theory of the supersymmetric SU(2)$_H$ gauge thoery that causes confinement. In this effective theory, we study the parameter region where electroweak phase transition is of strongly first order, as required for successful electroweak baryogenesis. In such a parameter region, the model has a Landau pole at the order of 10 TeV, which corresponds to the confinement scale of the SU(2)$_H$ gauge theory. We find that the large coupling constant which blows up at the Landau pole results in large non-decoupling loop effects on low-energy observables, such as the Higgs-photon-photon vertex and the triple Higgs boson vertex. As phenomenological consequences of electroweak baryogenesis in our model, the Higgs-to-diphoton branching ratio is about 20% smaller while the triple Higgs boson coupling is more than about 20% larger than the standard model predictions. Such deviations may be detectable in future collider experiments.
Self-Consistent Magnetic Stellar Evolution Models of the Detached, Solar-Type Eclipsing Binary EF Aquarii

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We introduce a new one-dimensional stellar evolution code, based on the existing Dartmouth code, that self-consistently accounts for the presence of a globally pervasive magnetic field. The methods involved in perturbing the equations of stellar structure, the equation of state, and the mixing-length theory of convection are presented and discussed. As a first test of the code's viability, stellar evolution models are computed for the components of a solar-type, detached eclipsing binary (DEB) system, EF Aquarii, shown to exhibit large disagreements with stellar models. The addition of the magnetic perturbation corrects the radius and effective temperature discrepancies observed in EF Aquarii. Furthermore, the required magnetic field strength at the model photosphere is within a factor of two of the magnetic field strengths estimated from the stellar X-ray luminosities measured by ROSAT and those predicted from Ca II K line core emission. These models provide firm evidence that the suppression of thermal convection arising from the presence of a magnetic field is sufficient to significantly alter the structure of solar-type stars, producing noticeably inflated radii and cooler effective temperatures. The inclusion of magnetic effects within a stellar evolution model has a wide range of applications, from DEBs and exoplanet host stars to the donor stars of cataclysmic variables.

description: We study the primordial density perturbations and non-Gaussianities generated from the combined effects of an inhomogeneous end of inflation and curvaton decay in hybrid inflation. This dual role is played by a single isocurvature field which is massless during inflation but acquire a mass at the end of inflation via the waterfall phase transition. We calculate the resulting primordial non-Gaussianity characterized by the non-linearity parameter, $f_{NL}$, recovering the usual end-of-inflation result when the field decays promptly and the usual curvaton result if the field decays sufficiently late.

description: Pushing data traffic from cellular to WiFi is an example of inter radio access technology (RAT) offloading. While this clearly alleviates congestion on the over-loaded cellular network, the ultimate potential of such offloading and its effect on overall system performance is not well understood. To address this, we develop a general and tractable model that consists of $M$ different RATs, each deploying up to $K$ different tiers of access points (APs), where each tier differs in transmit power, path loss exponent, deployment density and bandwidth. Each class of APs is modeled as an independent Poisson point process (PPP), with mobile user locations modeled as another independent PPP, all channels further consisting of i.i.d. Rayleigh fading. The distribution of rate over the entire network is then derived for a weighted association strategy, where such weights can be tuned to optimize a particular objective. We show that the optimum fraction of traffic offloaded to maximize $\SINR$ coverage is not in general the same as the one that maximizes rate coverage, defined as the fraction of users achieving a given rate.

description: We present a theoretical model for the experimentally found but counter-intuitive exceptionally long lifetime of surface nanobubbles. We can explain why, under normal experimental conditions, surface nanobubbles are stable for many hours or even up to days rather than the expected microseconds. The limited gas diffusion through the water in the far field, the cooperative effect of nanobubble clusters, and the pinned contact line of the nanobubbles lead to the slow dissolution rate.

description: Three different organic compounds, 2-phenyl-5-(4-trifloromethyl phenyl sulfonamido) benzoxazole (PTPS), 2-(4-chlorobenzyl)-5-(2,4-dinitrophenylsulfonamido)benzoxazole (CNSB) and 2-(4-fluorobenzyl)-5-(2,4-dinitrophenylsulfonamido)benzoxazole (FBPS), were synthesized. To find their energetically stable conformation, geometry optimization was done using density functional theory with the level B3LYP/cc-pVDZ. Electron distribution of the system was studied using molecular electrostatic potential map. Different intermolecular interactions arising from hyperconjugative effect were investigated using the natural bond orbital (NBO) formalism. Nonlinear optical properties were further studied using first-order hyperpolarizability values. The three compounds may be important in the development of novel inhibitor molecules of Topoisomerase II enzyme, as lead compounds. Light harvesting efficiency of PTPS is 0.9342, which shows that it is having potential applications in the design of new DSSC's.

description: In order to explore some general features of modified theories of gravity which involve higher derivatives and spontaneous Lorentz and/or diffeomorphism symmetry breaking, we study the recently proposed new version of covariant renormalizable gravity (CRG). CRG attains power-counting renormalizability via higher derivatives and introduction of a constrained scalar field and spontaneous symmetry breaking. We obtain an Arnowitt-Deser-Misner representation of the CRG action in four-dimensional spacetime with respect to a foliation of spacetime adapted to the constrained scalar field. The resulting action is analyzed by using Hamiltonian formalism. We discover that CRG contains two extra degrees of freedom. One of them carries negative energy (a ghost) and it will destabilize the theory due to its interactions. This result is in contrast with the original paper [Phys. Lett. B 701, 117 (2011), arXiv:1104.4286 [hep-th]], where it was concluded that the theory is free of ghosts and renormalizable when we analyze fluctuations on the flat background.

description: Galaxies and galaxy clusters have rotational velocities apparently too fast to allow them to be gravitationally bound by their visible matter. This has been attributed to the presence of invisible (dark) matter, but so far this has not been directly detected. Here, it is shown that a new model that modifies inertial mass by assuming it is caused by Unruh radiation, which is subject to a Hubble-scale (Theta) Casimir effect predicts the rotational velocity (v) to be: v^4=2GMc^2/Theta (the Tully-Fisher relation) where G is the gravitational constant, M is the baryonic mass and c is the speed of light. The model predicts the outer rotational velocity of dwarf and disk galaxies, and galaxy clusters, within error bars, without dark matter or adjustable parameters, and makes a prediction that local accelerations should remain above 2c^2/Theta at a galaxy's edge.

description: We consider small perturbations of the Laplace operator in a multi-dimensional cylindrical domain by second order differential operators with periodic coefficients. We show that under certain non-degeneracy conditions such perturbations can open a gap in the continuous spectrum and give the leading asymptotic terms for the gap edges. We also estimate the values of quasi-momentum at which the spectrum edges are attained. The general machinery is illustrated by several new examples in two- and three-dimensional structures.

description: Ο σκοπός της εργασίας εστιάζεται στην ανάδειξη της διδασκαλίας της Ορθόδοξης Εκκλησίας για το φυσικό περιβάλλον. Βαρύνουσα σημασία αποκτά η αναζήτηση της βαθύτερης αιτίας της οικολογικής κρίσης και η εξεύρεση της ιδανικής λύσης για την καλύτερη αντιμετώπιση. Στη διαχείριση της οικολογικής κρίσης με προοπτική τη σωτηριολογική διάσταση, ιδιαίτερη αναφορά γίνεται στον άνθρωπο, καθώς δίχως αλλαγή στον άνθρωπο δεν αναμένεται μια ριζική αντιμετώπιση της υπάρχουσας κατάστασης. Ο άνθρωπος καλείται να συλλογιστεί και να δράσει υπό το πρίσμα μιας νέας ρητορικής, της αειφορίας. Το σύστημα κοινωνία-περιβάλλον-οικονομία θα καθορίσει τις επόμενες κινήσεις του ανθρώπου, οι οποίες θα φανερώνουν περισσότερο σεβασμό, συνετή διαχείριση, φροντίδα και μέριμνα για τα οικολογικά προβλήματα. Σε σχέση με τα παραπάνω η εργασία ολοκληρώνεται με την εκπόνηση μιας διδακτικής παρέμβασης βασισμένης στις αρχές και στις τεχνικές της Υπαίθριας Εκπαίδευσης.
description: This thesis aims at highlighting Orthodox Church teaching in the natural environment. The main focus is the research of the primitive cause of the ecological crisis and the discovery of the optimum solution for the best treatment. While managing the ecological crisis with prospect the soteriological dimension, certain reference is dedicated to the human genre, as without human change there will not be any chance of finding a radical solution to the current situation. Humans are called to think and act within the new rhetoric and sustainability. The system society- environment- economy will determine the future human moves, which will demonstrate more respect, wise management ,care and concern for the ecological problems. In relation to all the above stated, the thesis is completed with conducting a teaching intervention, based on the principles and techniques of outdoor education.

description: Σκοπός της διατριβής είναι να παρουσιάσει το μυστήριο του ευχελαίου αλλά και να προβάλει τη χρήση του ως σωματικό και ψυχικό θεραπευτικό μέσο. Εξετάσαμε την χρήση του ελαίου στην αρχαία Ελλάδα αλλά και στον Ιουδαϊκό κόσμο. Στην συνέχεια παρουσιάσαμε την λειτουργική χρήση αλλά και την μυστηριακή υπόσταση του ελαίου στα μυστήρια του Βαπτίσματος, Χρίσματος και Ευχελαίου καθώς και την σχέση του τελευταίου με το μυστήριο της Μετάνοιας. Ακόμα αναφερθήκαμε στις διάφορες παρανοήσεις και δεισιδαιμονίες του μυστηρίου του Ευχελαίου. Αποσαφηνίσαμε τον ορισμό της ψυχοσωματικής ασθένειας. Ένα άλλο θέμα που θίξαμε είναι η συνέργεια και η σωστή χρήση του αυτεξουσίου του ασθενή στο θαύμα της θεραπείας και τέλος στην παιδαγωγική αξία του μυστηρίου μέσα από τα ψαλλόμενα και αναγινωσκόμενα κατά την διάρκεια της τελέσεως του μυστηρίου. Τελειώσαμε με την θέση που κατέχει το μυστήριο του αγίου ελαίου στην συνείδηση του σύγχρονου χριστιανού.
description: The purpose of the thesis is to present its Euchelian mystery but also to highlight its use as a physical and mental therapeutic agent. We examined the use of oil in ancient Greece and also in the Jewish world. Then we presented the liturgical use and the sacramental essence of the oil in the sacraments of Baptism, Anointing, Euchelian mystery and the as well as the relationship of the latter with the sacrament of Repentance. We also referred to the various misconceptions and superstitions of the Euchelian mystery. We clarified the definition of psychosomatic illness. Another topic we touched on is the synergy and the correct use of the patient's autonomy in the miracle of healing and finally in the pedagogical value of the sacrament through the things chanted and renewed during the performance of the sacrament. We are done with the place held by the mystery of the holy oil in the consciousness of the modern Christian.

description: Through detailed radiative transfer modeling, we present a disk+cavity model to simultaneously explain both the SED and Subaru H-band polarized light imaging for the pre-transitional protoplanetary disk PDS 70. Particularly, we are able to match not only the radial dependence, but also the absolute scale, of the surface brightness of the scattered light. Our disk model has a cavity 65 AU in radius, which is heavily depleted of sub-micron-sized dust grains, and a small residual inner disk which produces a weak but still optically thick NIR excess in the SED. To explain the contrast of the cavity edge in the Subaru image, a factor of ~1000 depletion for the sub-micron-sized dust inside the cavity is required. The total dust mass of the disk may be on the order of 1e-4 M_sun, only weakly constrained due to the lack of long wavelength observations and the uncertainties in the dust model. The scale height of the sub-micron-sized dust is ~6 AU at the cavity edge, and the cavity wall is optically thick in the vertical direction at H-band. PDS 70 is not a member of the class of (pre-)transitional disks identified by Dong et al. (2012), whose members only show evidence of the cavity in the millimeter-sized dust but not the sub-micron-sized dust in resolved images. The two classes of (pre-)transitional disks may form through different mechanisms, or they may just be at different evolution stages in the disk clearing process.

description: To interpret the measurements in heavy-ion collisions at the Relativistic Heavy-Ion Collider (RHIC) it is crucial to understand the initial state of the colliding gold (Au) nuclei. The parton distribution in Au nuclei is modified compared to protons, and their isospin composition is different due to the presence of neutrons. d+Au collisions at RHIC at the same collision energies are an important tool to study initial state modifications. PHENIX has measured pi0, eta, and reconstructed jets at high transverse momentum. These data are compared to predictions from nuclear parton distribution functions. Furthermore, single electrons from heavy-flavor decays have been measured by PHENIX.

description: This thesis examines the relationship between immigrant generation and early adulthood incorporation into higher education and work. Using data from the High School and Beyond Sophomore cohort I explore when and where disparities between the children of immigrants and their native-born, native parent peers emerge. I find that the relationship between immigrant generation and post-secondary education enrollment and early adulthood employment varies by gender. Furthermore, it is at the entry points into higher education and work that disparities emerge. This research indicates that entry into social institutions should be considered as likely sites of inequality and that processes of incorporation may be gendered.
Contesting détente : European challenge to the Yalta order in the late 1960s

description: This master’s thesis analyzes the tensions and anxieties that surrounded the term “détente,” particularly when it came to European affairs, in the late 1960s. It argues that during the last years of the 1960s, 1966-1969, different approaches to détente clashed and influenced each other to create a certain ambiguous atmosphere within the European space, which formed the overall understanding of Europe’s future at the time; Prague Spring, the ultimate geopolitical crisis of the time, was formed and resolved in accordance to these notions. On the one hand, there was a top-down movement, mostly dominated by policymakers from the United States and the Soviet Union, but sometimes embraced by Western European statesmen, to define détente through an entrenchment of the Yalta order. The idea was that mutual acknowledgment of the status quo in Europe would allow for a creation of a commonly accepted and controllable framework for states to cooperate. In parallel, a bottom-up movement consisting of Western and Eastern European believers in European unity as the most rational and effective possible manifestation of détente, existed to challenge and influence the prescriptive nature of détente that was embraced by the superpowers. These idealists sought to define détente as a drive towards the abandonment of the Yalta order and unification of the continent on European terms, thus diminishing the importance of the Iron Curtain, which was seen as the cause of global instability. Overall, this master’s thesis provides an insight into how a term that is widely used to describe a period of time, “détente,” was formed and conceptualized within the central arena of the Cold War – Europe. Its aim is to serve as a think piece that reevaluates the discourses surrounding détente and to position them not as mere products of Cold War bipolar international order, but as ideas rooted in thoughts on European unity and future. Different interpretations of the term “détente” that floated around the continent in the 1960s would later define European unification under the auspices of the European Union in the 1990s and early 2000s.
