title: Communication planning for development: an operational framework
Creators: name: Hancock, Alan
Publisher: name: The Open University
Year: 1980

description: This thesis is concerned with communication planning for national development: specifically with the problem of utilising a developing country's communication resources to support an integrated programme of social, political and economic mobilisation. The research which it describes sets out to construct, and test, an operational planning framework, to include among its parameters decision-making processes and political factors as well as planning strategies for communication. Following a literature search, a number of guiding principles in support of communication planning are hypothesized. These principles are then evaluated, modified and categorised, through comparison with selected communication projects and surveys, at levels ranging from the local to the national and regional. Subsequently, on the basis of this analysis, an experimental planning framework is devised, which is constructed around two basic axes: the first defining planning participants (including both planners and decision-makers), and the second defining the sequence of planning. A particular emphasis in elaborating this framework is on the relationship between communication and development planning, and on interactions between the various sectors concerned with national development. An account is then given of a field test of the experimental framework in a developing country (Afghanistan); during which independent evaluations of both the framework and of its application were carried out. Following an analysis of these evaluations, the framework is modified and a revised version proposed. Finally, an attempt is made to relate the planning framework to current concerns with popular access to communication resources, and participation in communication planning and management, as a guide to future application and evaluation.

description: An action minimizing path between two given configurations, spatial or planar, of the $n$-body problem is always a true -- collision-free -- solution. Based on a remarkable idea of Christian Marchal, this theorem implies the existence of new "simple" symmetric periodic solutions, among which the Eight for 3 bodies, the Hip-Hop for 4 bodies and their generalizations.

description: Observations of hot stars belonging to the young cluster LMC-NGC2004 and its surrounding region have been obtained with the VLT-GIRAFFE facilities in MEDUSA mode. 25 Be stars were discovered; the proportion of Be stars compared to B-type stars is found to be of the same order in the LMC and in the Galaxy fields. 23 hot stars were discovered as spectroscopic binaries (SB1 and SB2), 5 of these are found to be eclipsing systems from the MACHO database, with periods of a few days. About 75% of the spectra in our sample are polluted by hydrogen (Halpha and Hgamma), [SII] and [NII] nebular lines. These lines are typical of HII regions. They could be associated with patchy nebulosities with a bi-modal distribution in radial velocity, with higher values (+335 kms^{-1}) preferentially seen inside the southern part of the known bubble LMC4 observed in HI at 21 cm.

Subjects: subject: 620 Ingenieurwissenschaften und zugeordnete Tätigkeiten

description: Die Erschließung von Neubauflächen, steigende Bauwerkslasten und strengere Anforderungen an Setzungen und Setzungsdifferenzen führen zu einem steigenden Bedarf an Tiefgründungsmaßnahmen. Eine relativ junge Entwicklung auf diesem Gebiet ist die Anwendung von Stabilisierungssäulen (StS) und pfahlähnlichen Tragelementen als Alternative zur konventionellen Pfahlgründung. Auf Grund der im Vergleich zum Pfahl geringeren Tragfähigkeit der StS werden diese zumeist als „Säulenwald“ angeordnet und die abzutragende Last über eine Lasttransferschicht (LTS) auf die einzelnen StS abgeleitet. Zusätzlich wird häufig eine oder mehrere Geogitterlagen eingebracht, was zur Erhöhung des Lastanteils der StS führt. Ein gängies Anwendungsbeispiel hierfür ist z.B. die Gründung eines Damms. Über die Lastaufteilung zwischen StS und anstehender Weichschicht wurden im Laufe der Jahre verschiedenste Theorien und Berechnungsansätze veröffentlicht. Zunächst wird eine Auswahl verschiedener geschlossener Berechnungsansätze für den 3-dimensionalen Fall vorgestellt und miteinander verglichen. Diesen ist gemein, dass für die Lastaufteilung lediglich die bodenmechanischen Eigenschaften der LTS und die geometrischen Parameter benötigt werden. Eine Berücksichtigung der anstehenden Weichschicht ist z.B. bei der iterativen Berechnung mittels Lasttransfermethode oder bei FE-Berechnungen möglich. Diese Ansätze werden, da durch die Berücksichtigung der Eigenschaften der Weichschicht weitere Freiheitsgrade entstehen, gesondert miteinander verglichen. Abschließend wird an Hand zweier Beispiele die Komplexität der Problemstellung „Ermittlung der Laustaufteilung zwischen StS und WS“ aufgezeigt.
Suppression of turbulence and travelling waves in a vertical heated pipe

description: Turbulence in the flow of fluid through a pipe can be suppressed by buoyancy forces. As the suppression of turbulence leads to severe heat transfer deterioration, this is an important and undesirable phenomenon in both heating and cooling applications. Vertical flow is often considered, as the axial buoyancy force can help drive the flow. With heating measured by the buoyancy parameter $C$, our DNS show that shear-driven turbulence may either be completely laminarised or transitions to a relatively quiescent convection-driven state. Buoyancy forces cause a flattening of the base flow profile, which in isothermal pipe flow has recently been linked to complete suppression of turbulence (Kühnen et al. Nat. Phys., 2018), and the flattened laminar base profile has enhanced nonlinear stability (Marensi et al. JFM, 2019). In agreement with these findings, the nonlinear lower-branch travelling-wave solution analysed here, which is believed to mediate transition to turbulence in isothermal pipe flow, is shown to be suppressed by buoyancy. A linear instability of the laminar base flow is responsible for the appearance of the relatively quiescent convection driven state for $C\gtrsim 4$ across the range of Reynolds numbers considered. In the suppression of turbulence, however, i.e. in the transition from turbulence, we find clearer association with the analysis of He et al. (JFM, 2016) than with the above dynamical systems approach, which describes better the transition to turbulence. The laminarisation criterion He et al. propose, based on an apparent Reynolds number of the flow as measured by its driving pressure gradient, is found to capture the critical $C=C_{cr}(Re)$ above which the flow will be laminarised or switch to the convection-driven type. Our analysis suggests that it is the weakened rolls, rather than the streaks, which appear to be critical for laminarisation.

These experiments show that the staggered moment of Ce and the incommensurate magnetic structure change weakly with applied pressure up to 1.63 GPa, where resistivity, specific heat and NQR measurements confirm the presence of bulk superconductivity. This work places new constraints on an interpretation of the relationship between antiferromagnetism and unconventional superconductivity in CeRhIn$_{5}$.

A random journey through dynamics and finance: pullback attractors, price impact, nonlinear valuation and FX market.
Creators: name: Graceffa, Federico
Publisher: name: Imperial College London
Year: 2021

description: The main objective of this thesis is to explore several areas of Random Dynamical Systems and Mathematical Finance. We start by considering random dynamical systems with two different sources of noise, which we call common and intrinsic. We study the interplay between these two sources of randomness from a novel point of view, going beyond the usual statistical approach. We determine the stochastic Fokker-Planck equation describing the system and prove that such equation has a pullback attractor for almost all realizations of the common noise. On the mathematical finance side, we start by discussing consistency properties of jump-diffusion models with respect to inversion, with applications to the Foreign Exchange market. We first solve the constant jump size case, and then analyze the more involved case of the compound Poisson process. We determine a fairly general class of admissible densities for the jump size in the domestic measure. Then, we delve into the nonlinear valuation framework under credit risk, collateral and funding costs, generalizing the mathematical framework of \cite{brigo2019nonlinear} for what concerns in particular the filtrations and the default times. Finally, we propose a first theory of price impact in presence of an interest-rates term structure. We formulate an instantaneous and transient price impact model for zero-coupon bond, defining a cross price impact that is endogenous to the term structure. We extend this setup to coupon-bearing bonds, HJM framework and conclude by solving an optimal execution problem in interest rates market.
Multiple-Scales Approach to The Averaging Problem in Cosmology

description: The Universe is homogeneous and isotropic on large scales, so on those scales it is usually modelled as a Friedmann-Lemaître-Robertson-Walker (FLRW) space-time. The non-linearity of the Einstein field equations raises concern over averaging over small-scale deviations form homogeneity and isotropy, with possible implications on the applicability of the FLRW metric to the Universe, even on large scales. Here I present a technique, based on the multiple-scales method of singular perturbation theory, to handle the small-scale inhomogeneities consistently. I obtain a leading order effective Einstein equation for the large-scale space-time metric, which contains a back-reaction term. The derivation relies on a series of consistency conditions, that ensure that the growth of deviations from the large-scale space-time metric do not grow unboundedly; criteria for their satisfiability are discussed, and it is shown that they are indeed satisfied if matter is non-relativistic on small scales. The analysis is performed in harmonic gauge, and conversion to other gauges is discussed. I estimate the magnitude of the back-reaction term relative to the critical density of the Universe in the example of an NFW halo, and find it to be of the order of a few percent. In this example, the back-reaction term is interpreted as a contribution of the energy-density of gravitational potential energy, averaged over the small-scale, to the total energy-momentum tensor.

description: The melting of Al clusters in the size range 49 <= N <= 62 has been studied using two model interatomic potentials. The results for the two models are significantly different. The glue potential exhibits a smooth relatively featureless heat capacity curve for all sizes except for N = 54 and N = 55, sizes at which icosahedral structures are favoured over the polytetrahedral. Gupta heat capacity curves, instead, show a well-defined peak that is indicative of a first-order-like transition. The differences between the two models reflect the different ground-state structures, and neither potential is able to reproduce or explain the size dependence of the melting transition recently observed in experiments.

description: We study the current tunable microwave signal properties of nano-constriction based spin Hall nano-oscillators (SHNOs) in oblique magnetic fields as a function of the nano-constriction width, $w=$~50--140 nm. The threshold current is found to scale linearly with $w$, defining a constant threshold current density of $J_{th}=$ 1.7 $\times$ 10$^{8}$ A/cm$^2$. While the current dependence of the microwave frequency shows the same generic non-monotonic behavior for all $w\geqslant$ 80 nm, the quality of the generated microwave signal improves strongly with $w$, showing a linear $w$ dependence for both the total power and the linewidth. As a consequence, the peak power for a 140 nm nano-constriction is about an order of magnitude higher than that of a 80 nm nano-constriction. The smallest nano-constriction, $w=$ 50 nm, exhibits a different behavior with a higher power and a worse linewidth indicating a crossover into a qualitatively different narrow-constriction regime.
title: Permeation studies of hydrogen, deuterium and helium in aluminium, gold molybdenum and silver: the influence of phase boundary processes
Creators: name: Faraj, Eser
Publisher: name: The Open University
Year: 1981

description: The diffusivity of; hydrogen through aluminium, gold, molybdenum and silver; deuterium through gold, molybdenum and silver; helium through aluminium, gold and silver has been studied by a modified response time method using periodically modulated discharge and ion beam injection at the input surface. Measurements consisted of the response time of pressure, across a metal membrane, in the detection chamber due to fluctuations at the input. The downstream vacuum chamber was continuously pumped. The relationship between the time-lag of the downstream pressure relative to the upstream pressure yielded the diffusion coefficient. The permeability of hydrogen and deuterium through molybdenum and gold were determined from separate time independent measurements of the flux through the membrane. The relationships for the time-lags and steady rate fluxes were modified when account was taken of the possible importance of surface processes in permeation. The modified relations were found necessary when analysing the data of aluminium and gold.

description: We report unambiguous experimental evidence of broken time reversal symmetry for the interaction of light with an artificial non-magnetic material. Polarized colour images of planar chiral gold-on-silicon nanostructures consisting of arrays of gammadions show intriguing and unusual symmetry: structures, which are geometrically mirror images, loose their mirror symmetry in polarized light. The symmetry of images can only be described in terms of anti-symmetry (black-and-white symmetry) appropriate to a time-odd process. The effect results from a transverse chiral non-local electromagnetic response of the structure and has some striking resemblance with the expected features of light scattering on anyon matter.

description: In this paper, we argue that differences in the cost structures across sectors play an important role in firms’ decisions to adjust their prices. We develop a menu-cost model of pricing in which retail firms intermediate trade between producers and consumers. An important facet of our analysis is that the labor-cost share of retail production differs across goods and services in the consumption basket. For example, the price of gasoline at the retail pump is predicted to adjust more frequently and by more than the price of a haircut because of the high volatility in wholesale gasoline prices relative to the wages of unskilled labor, even when both retailers face a common menu cost. This modeling approach allows us to account for some of the cross-sectional differences observed in the frequency of price adjustments across goods. We apply this model to Ecuador to take advantage of inflation variations and the rich panel of monthly retail prices.
description: Dans cet article, nous avançons que les différences de structures de coûts entre les secteurs jouent un rôle essentiel dans les décisions des entreprises de rajuster leurs prix. Nous recourons à un modèle à coûts d’étiquetage dans lequel les détaillants servent d’intermédiaires commerciaux entre les producteurs et les consommateurs. L’un des aspects importants de notre analyse tient au fait que la part associée aux coûts de maind’oeuvre dans la production au détail diffère d’un bien et d’un service à l’autre dans le panier de consommation. À titre d’exemple, le modèle prédit un rajustement du prix de l’essence à la pompe plus fréquent et plus marqué que celui du prix d’une coupe de cheveux en raison de la grande volatilité des prix de gros de l’essence par rapport aux salaires des travailleurs non spécialisés, même lorsque les deux détaillants doivent composer avec des coûts d’étiquetage identiques. Cette méthode de modélisation nous permet de tenir compte de certaines des différences transversales observées dans la fréquence de rajustement des prix selon les biens. Nous appliquons ce modèle à l’Équateur pour tirer avantage des variations de l’inflation et d’un riche ensemble de données sur les prix de détail mensuels.

description: Collective excitations in liquids are important for understanding liquid dynamical and thermodynamic properties. Gapped momentum states (GMS) are a notable feature of liquid dynamics predicted to operate in the transverse sector of collective excitations. Here, we combine inelastic neutron scattering experiments, theory and molecular dynamics modelling to study collective excitations and GMS in liquid Ga in a wide range of temperature and $k$-points. We find that all three lines of enquiry agree for the longitudinal sector of liquid dynamics. In the transverse sector, the experiments agree with theory, modelling as well as earlier X-ray experiments at larger $k$, whereas theory and modelling agree in a wide range of temperature and $k$-points. We observe the emergence and development of the $k$-gap in the transverse sector which increases with temperature and inverse of relaxation time as predicted theoretically.

description: In this paper, we calculate the decay rate and CP asymmetry of the $B_s \to π^+π^-$ decay in perturbative QCD approach with Sudakov resummation. Since none of the quarks in final states is the same as those of the initial $B_s$ meson, this decay can occur only via annihilation diagrams in the standard model. Besides the current-current operators, the contributions from the QCD and electroweak penguin operators are also taken into account. We find that (a) the branching ratio is about $4 \times 10^{-7}$; (b) the penguin diagrams dominate the total contribution; and (c) the direct CP asymmetry is small in size: no more than $3% $; but the mixing-induced CP asymmetry can be as large as ten percent testable in the near future LHC-b experiments.

description: To ensure the water availability from small dams in the Pothwar Plateau of Punjab, two dams namely Khasala and Jawa were investigated. Pothwar Plateau has erratic rainfall pattern and depends on rainfall for agriculture production. The construction of small dams in this region provides a lifeline to the farmer’s community. The Government of Punjab has constructed 55 small dams in this region to facilitate the farmers in terms of irrigation services. The selected dams have potential to irrigate the culturable command area but due to poor water managements services and absence of agriculture extension services, farmers produce low agriculture yield and hesitate to cultivate more land. Water availability from these dams is more important than construction of small dams. Some farmers in the study area use dug-wells for irrigation purposes and bear a high cost of production. The several bottlenecks existing in the full utilization of dam’s water are mentioned as: failure of warabandi system, absence of water user associations, broken water channels, blockage of water courses, improper maintenance of water channels and absence of water management services. The Government of Punjab (GOP) and Small Dams Organization (SDO) need more efforts to facilitate the farmers in terms of irrigation services and effective water management practices are desirable to enhance the agriculture production in the Pothwar region.
title: Handel and the English Chapel Royal during the reigns of Queen Anne and King George I
Creators: name: Burrows, Donald James
Publisher: name: The Open University
Year: 1981

description: Handel's association with the English Chapel Royal began soon after he settled in London, and continued intermittently for the remainder of his life. ' The thesis traces this association until'the death of King George I in 1727. Handel's Chapel Royal music is examined with dual reference to the Chapel's musical traditions and the development of the composer's style. Political events influenced the extent of Handel's involvement with the Chapel at different periods: the relationship between the composers, the Chapel Royal and the British Court is described within the historical contexts drawing on many unpublished sources. After an introductory survey of the repertoire of Handel's Chapel Royal music, the musical history of the Chapel during the period preceding Handel's arrival in London is described, paying special attention to performances of instrumentally-accompanied services and anthems, and the ceremonial Thanksgiving Services of Queen Anne's reign. Handel's experience of church music In Italy and Germany previous to his arrival in England is described, and the contemporary English anthems of William Croft are examined by way of an introduction to Handel's first English Verse Anthem. Two chapters are devoted, to Handel's Chapel Royal compositions from the period 1710-1714, including his music celebrating the Peace of Utrecht. Chapters 6 and 7 investigate the circumstances surrounding Handel's disassociation from the Chapel in 1715-1722 and his subsequent re-establishment there during the last years of George I's reign. The significance, of Handel's appointment as Composer to the Chapel is considered, and a chronology for his Chapel Royal music from the 1720p suggested. The music is examined in detail, and described with reference to related antecedent Chandos Anthems., The later history of Handel's Chapel Royal music is surveyed briefly in the final chapter. Factual background material is collected in an extended supplement and fifteen appendices.

description: This paper introduces a new methodology to date systemic financial stress events in a transparent, objective and reproducible way. The financial cycle is captured by a monthly country-specific financial stress index. Based on a Markov-switching model, high financial stress regimes are identified, and a simple algorithm is used to select those episodes of financial stress that are associated with a substantial negative impact on the real economy. By applying this framework to 27 European Union countries, the paper is a first attempt to provide a chronology of systemic financial stress episodes in addition to the expert-detected events that are currently available.
description: L’article qui suit présente une nouvelle méthode permettant de dater les événements porteurs de tensions financières systémiques de façon transparente, objective et reproductible. Le cycle financier est représenté par un indice mensuel de tensions financières propre à chaque pays. À l’aide d’un modèle de Markov avec changement de régime, les événements caractérisés par de fortes tensions financières sont recensés, après quoi sont sélectionnés, au moyen d’un algorithme simple, les épisodes de tensions associés à un effet négatif important sur l’économie réelle. Par l’application de ce cadre analytique à 27 pays de l’Union européenne, l’article constitue une première tentative d’établir une chronologie des épisodes de tensions financières systémiques, en complément des événements actuellement identifiés par les spécialistes.

description: We describe the design, commissioning and operation of an ultra-low-vibration closed-cycle cryogenic ion trap apparatus. One hundred lines for low-frequency signals and eight microwave / radio frequency coaxial feed lines offer the possibility of implementing a small-scale ion-trap quantum processor or simulator. With all supply cables attached, more than 1.3 W of cooling power at 5 K is still available for absorbing energy from electrical pulses introduced to control ions. The trap itself is isolated from vibrations induced by the cold head using a helium exchange gas interface. The performance of the vibration isolation system has been characterized using a Michelson interferometer, finding residual vibration amplitudes on the order of 10 nm rms. Trapping of $^9$Be$^+$ ions has been demonstrated using a combination of laser ablation and photoionization.

description: In the 1960s and 1970s a large part of the theory of dynamical systems concerned the case of uniformly hyperbolic or Axiom A dynamical system and abstract ergodic theory of smooth dynamical systems. However since around 1980 an emphasize has been on concrete examples of one-dimensional dynamical systems with abundance of chaotic behavior (Collet &Eckmann and Jakobson). New proofs of Jakobson's one-dimensional results were given by Benedicks and Carleson \cite{BC85} and were considerably extended to apply to the case of Hénon maps by the same authors \cite{BC91}. Since then there has been a considerable development of these techniques and the methods have been extended to the ergodic theory and also to other dynamical systems (work by Viana, Young, Benedicks and many others). In the cases when it applies one can now say that this theory is now almost as complete as the Axiom A theory.

description: Purpose. Poverty in Pakistan mostly exists as a rural poverty rather than urban poverty and presents a desolate vision. Rural poverty shows divergence with respect to area, region or any other administrative division. The tenacious rise of rural poverty in the history of Pakistan with some omissions, it affords plenty of material and remains a lot of questions related to poverty in the mind of researchers. The current study focused on three main poverty measures i.e. incidence, depth and severity of rural poverty in the rice-wheat zone of Punjab, Pakistan (Middle Punjab).Methodology / approach. To overcome the existing poverty issues in the area, we utilize secondary datasets at districts, regions, provinces or at national levels collected from Pakistan Bureau of Statistics, Islamabad (PBS). Poverty assessment for the year 2011–2012 is analyzed through Foster Greer and Thorbecke (FGT) method. Moreover, the Logit model is also used to find out the empirical values existing in the datasets.Results. The fluctuations in rural poverty for the year 2011–12 in the existing zone was analyzed by using logit regression model and data source was Household Integrated Economic Survey (HIES). The incidence of uni-dimensional and multidimensional poverty in middle Punjab (2011–12) were 35.38 and 27.40 percent has been seen after estimations.Originality / scientific novelty. The education level, health services, availability of assets, facilities and age of household head are the key factors related to incidence, depth and severity of poverty. All the above mentioned factors have negative relation with poverty measures.Practical value / implications. The decline in poverty can be achieved via implementation of sharp economic activities including the dimensions as analyzed in the manuscript. At this point, policy makers did not pay attention on the key factors that influence rural poverty at regional levels. There is a dire need to make development in basic standards of life to alleviate poverty in a long way in the middle Punjab.
Beyond energy futures : an exploration of sustainability-driven and transition dynamics-driven approaches to guiding socio-technical change

description: Energy technologies and systems are imperative for the proper functioning of our economies and societies, but due to their growing environmental and social impacts, there appears to be an interest in making a transition toward alternative forms of energy systems. However, making such a transition would involve understanding the complex characteristics of energy technologies, their interdependencies, sustainability impacts and socio-technical contexts, therefore, it calls for an inter-disciplinary approach to such an analysis. This dissertation proposes two approaches to informing future energy and technology policies. The first approach is motivated by the need to improve methods for sustainability assessment. While a variety of tools and methods exist for the assessment of sustainability, there appears to be no systematic approach to their selection and thus the design of sustainability assessments is often driven by convenience, familiarity and availability of tools. Therefore, a framework (Sustainability Assessment Framework) is proposed for a more systematic approach to tool selection and for the design of the next generation of sustainability assessments. The second approach is based on an attempt to understand the dynamics of technological transitions. Much of the literature on technological change focuses on technologies, but the technological transitions literature highlights the importance of thinking about transitions between socio-technical systems. This dissertation suggests that the guidance to socio-technical transitions may not come from choices made between technologies, but instead from choices made about desirable futures. The articulation of a desirable future may then enable compatible technologies currently within niches, to co-evolve and develop inter-dependencies with other compatible technologies and systems, thus initiating a possible socio-technical transition. It is argued that both approaches complement each other in informing energy and technology policy regarding transitions to future energy systems. While the first approach (sustainability-driven) allows us to assess the sustainability of future technologies and systems, the second approach (transition dynamics-driven) informs us about the dynamics of the transition process and urges us to think of transitions in terms of a desired future and its characteristics (i.e. sustainability characteristics). Together the two approaches inform us on how we might think about choosing and guiding a desirable future.

Defining the British Flute School : a study of British flute performance practice 1890-1940
Creators: name: Raposo, Jessica Ann

description: The British Flute School went through dramatic change in the twentieth century, as its leading players adopted elements of the French style of playing. These changes caused tensions that have led to a subjective oral history: a history which depicts two camps of flautists vying for the superior style, with one winner in the end. This document aims to provide a more comprehensive and more accurate history of the British Flute School from 1890 to 1940, and, through this investigation, explore what it means to define a style of playing in terms of both nationality and as a unified school. It will include not only an exploration of the interactions between the French and British flute schools, but also an in-depth examination of the influences of flautists of other nationalities, their career activities, performed repertoire, critical commentary in the press (primarily from The Musical Times and the London Times), British flute pedagogy, the recording industry, and aspects of the overarching musical culture in Great Britain. A survey of the active flautists of the time includes: John Amadio, Jean Firmin Brossa, Albert Cunningham, Edward De Jong, Louis Fleury, John Francis, Albert Fransella, Philippe Gaubert, Geoffrey Gilbert, Frederic Griffith, René Le Roy, Joseph Lingard, Gareth Morris, Marcel Moyse, Robert Murchie, Vincent Needham, Edith Penville, E. Stanley Redfern, Joseph Slater, and Lupton Whitelock. The document concludes with a proposal for a redefinition of the British Flute School that, like the culture from which it comes, values rather than disparages the diversity of its history.

description: Perovskite oxides ABO$_3$ containing heavy B-site elements are a class of candidate materials to host topological metals with a large spin-orbit interaction. In contrast to the band insulator BaSnO$_3$, the semimetal BaPbO$_3$ is proposed to be a typical example with an inverted band structure, the conduction band of which is composed of mainly the O-2p orbital. In this study, we exemplify a band-gap modification by systematic structural, optical, and transport measurements in BaSn$_{1-x}$Pb$_x$O$_3$ films. A sudden suppression of the conductivity and an enhancement of the weak antilocalization effect at $x$ = 0.9 indicate the presence of a singular point in the electronic structure as a signature of the band inversion. Our findings provide an intriguing platform for combining topological aspects and electron correlation in perovskite oxides based on band-gap engineering.

title: The petrology, geochemistry and structure of the plutonic rocks of the Oman ophiolite
Creators: name: Browning, Paul
Publisher: name: The Open University

description: The Oman Ophiolite represents a fragment of oceanic crust and upper mantle that was emplaced onto the Arabian continental margin during the late Cretaceous. An area of 3000km2, comprising the Haylayn and Rustaq Blocks, has been mapped and specific localities were investigated in order to examine the petrological and structural processes that operate during and subsequent to the formation of oceanic lithosphere at a spreading axis. Four successive plutonic suites have been recognized : (i) the Mantle Sequence, Cumulate Sequence and High Level Intrusives that form the lower part of the classic Penrose ophiolite stratigraphy, which has been intruded by three Later Plutonic Suites, (ii) the Late Trondhjemite-Gabbro Complexes, (iii) the Late Peridotite-Gabbro Complexes, and (iv) the Late Biotite Granites. The tectonite harzburgite of the Mantle Sequence represents the residuum formed during 177. partial melting of upward flowing fertile spinet lherzolite mantle at pressures of 20kB or more. The primary magmas generated (tholeiitic picrites, minimum MgO 14%) supplied a sub-oceanic spreading ridge magma chamber in which formed the layered mafic and ultramafic rocks of the Cumulate Sequence and the isotropic gabbros, diorites and trondhjemites of the High Level Intrusives. Structures and petrofabrics developed in the Mantle Sequence preserve lines and planes of mantle flow beneath the oceanic crust. Layering in the Cumulate Sequence formed in situ within a long-lived, dynamic, compositionally stratified, open system magma chamber. The Later Plutonic Suites record the post-spreading igneous history of the Oman Ophiolite. The Late Trondhjemite-Gabbro Complexes and the Late Peridotite-Gabbro Complexes reflect incipient arc formation and subsequent arc-rifting on and in young oceanic crust. The Late Biotite Granites are considered to be syn-emplacement plutons derived from the underthrust Arabian continental margin. A back-arc (marginal) basin rather than a major ocean basin is considered to be the likely tectonic setting in which these successive magmatic episodes occurred.

description: With the Spitzer Space Telescope Infrared Spectrograph (IRS) we have observed seven powerful FR2 radio galaxies and seven quasars. Both samples, the galaxies and the quasars, are comparable in isotropic 178 MHz luminosity (10^26.5 W/Hz < P 178MHz < 10^29.5 W/Hz) and in redshift range (0.05 < z < 1.5). We find for both samples similar distributions in the luminosity ratios of high- to low-excitation lines ([NeV] 14.3 mu / [NeII] 12.8 mu) and of high-excitation line to radio power ([NeV] 24.3 μ/ P 178MHz). This solves the long debate about the apparent difference of quasars and radio galaxies in favor of the orientation-dependent unified schemes. Furthermore, the luminosity ratio [OIII] 500.7 nm / [OIV] 25.9 mu of most galaxies is by a factor of ten lower than that of the quasars. This suggests that the optical emission from the central NLR is essentially absorbed (A_V} > 3) in the powerful FR2 galaxies and that the [OIII] 500.7 nm luminosity does not serve as isotropic tracer for testing the unified schemes.
