Propagation, linkage, and interaction of caldera ring-faults: comparison between analogue experiments and caldera collapse at Miyakejima, Japan, in 2000
Creators: name: Burchardt, Steffi
name: Walter, Thomas
Publisher: name: Springer-Verlag
Year: 2009

description: The formation of ring faults yields important implications for understanding the structural and dynamic evolution of collapse calderas and potentially associated ash-flow eruptions. Caldera collapse occurred in 2000 at Miyakejima Island (Japan) in response to a lateral intrusion. Based on geophysical data it is inferred that a set of caldera ring faults was propagating upward. To understand the kinematics of ring-fault propagation, linkage, and interaction, we describe new laboratory sand-box experiments that were analyzed through Digital Image Correlation (DIC) and post-processed using 2D strain analysis. The results help us gain a better understanding of the processes occurring during caldera subsidence at Miyakejima. We show that magma chamber evacuation induces strain localization at the lateral chamber margin in the form of a set of reverse faults that sequentially develops and propagates upwards. Then a set of normal faults initiates from tension fractures at the surface, propagating downwards to link with the reverse faults at depth. With increasing amounts of subsidence, interaction between the reverse- and normal-fault segments results in a deactivation of the reverse faults, while displacement becomes focused on the outer normal faults. Modeling results show that the area of faulting and collapse migrates successively outward, as peak displacement transfers from the inner ring faults to later developed outer ring faults. The final structural architecture of the faults bounding the subsiding piston-like block is hence a consequence of the amount of subsidence, in agreement with other caldera structures observed in nature. The experimental simulations provide an analogy to the observations and seismic records of caldera collapse at Miyakejima volcano, but are also applicable to caldera collapse in general.

description: For any complex reductive connected Lie group G, many of the structure constants of the ordinary cohomology ring H^*(G/B; Z) vanish in the Schubert basis, and the rest are strictly positive. We present a combinatorial game, the ``root game'', which provides some criteria for determining which of the Schubert intersection numbers vanish. The definition of the root game is manifestly invariant under automorphisms of G, and under permutations of the classes intersected. Although these criteria are not proven to cover all cases, in practice they work very well, giving a complete answer to the question for G=SL(7,C). In a separate paper we show that one of these criteria is in fact necessary and sufficient when the classes are pulled back from a Grassmannian. More generally If G' -> G is an inclusion of complex reductive connected Lie groups, there is an induced map H^*(G/B) -> H^*(G'/B') on the cohomology of the homogeneous spaces. The image of a Schubert class under this map is a positive sum of Schubert classes on G'/B'. We investigate the problem of determining which Schubert classes appear with non-zero coefficient. This is the vanishing problem for branching Schubert calculus, which plays an important role in representation theory and symplectic geometry, as shown in [Berenstein-Sjamaar 2000]. The root game generalises to give a vanishing criterion and a non-vanishing criterion for this problem.

A clear detection was achieved for LHS 2076 during a major flare and for CN Leo, where the line had been discovered before. For some other stars the situation is not quite clear. For CN Leo we investigated the timing behaviour of the Fe xiii line and report a high level of variability on a timescale of hours which we ascribe to microflare heating.

description: Here I review vectorial type condensation due to a non zero chemical potential associated to some of the global conserved charges of the theory. The phase structure is very rich since three distinct phases exists depending on the value assumed by one of the zero chemical potential vector self interaction terms. In a certain limit of the couplings and for large chemical potential the theory is not stable. This limit corresponds to a gauge type limit often employed to economically describe the ordinary vector mesons self interactions in QCD. Our analysis is relevant since it leads to a number of physical applications not limited to strongly interacting theories at non zero chemical potential.

description: Cortical visual prostheses have the potential to restore sight in people who are blind. These prostheses aim to provide high-resolution vision for critical tasks like object recognition and real-world navigation through electrode-based brain stimulation. However, the number of electrodes required in the brain to provide high-resolution artificial vision is not feasible due to neural tissue damage. Additionally, the simultaneous stimulation of multiple electrodes, a requirement for artificial vision generation, can lead to unexpected visual outcomes. This thesis presents novel stimulation strategies for addressing these prominent challenges that prevent high visual resolution from being attained.

description: A (closed) dynamical system is a notion of how things can be, together with a notion of how they may change given how they are. The idea and mathematics of closed dynamical systems has proven incredibly useful in those sciences that can isolate their object of study from its environment. But many changing situations in the world cannot be meaningfully isolated from their environment - a cell will die if it is removed from everything beyond its walls. To study systems that interact with their environment, and to design such systems in a modular way, we need a robust theory of open dynamical systems. In this extended abstract, we put forward a general definition of open dynamical system. We define two general sorts of morphisms between these systems: covariant morphisms which include trajectories, steady states, and periodic orbits; and contravariant morphisms which allow for plugging variables of some systems into parameters of other systems. We define an indexed double category of open dynamical systems indexed by their interface and use a double Grothendieck construction to construct a double category of open dynamical systems. In our main theorem, we construct covariantly representable indexed double functors from the indexed double category of dynamical systems to an indexed double category of spans. This shows that all covariantly representable structures of dynamical systems - including trajectories, steady states, and periodic orbits - compose according to the laws of matrix arithmetic.

description: The celebrated Sutherland-Einstein relation for systems at thermal equilibrium states that spread of trajectories of Brownian particles is an increasing function of temperature. Here, we scrutinize diffusion of underdamped Brownian motion in a biased periodic potential and analyse regimes in which a diffusion coefficient decreases with increasing temperature within finite temperature window. Comprehensive numerical simulations of the corresponding Langevin equation performed with unprecedented resolution allow us to construct phase diagram for the occurrence of the non-monotonic temperature dependence of the diffusion coefficient. We discuss the relation of the latter effect with the phenomenon of giant diffusion.

Considering the longitudinal and transverse polarization states of the Z boson and incoming polarized beams we find the 95% C.L. limits on the form factors $h_{3}^{Z}$, $h_{4}^{Z}$, $h_{3}^γ$ and $h_{4}^γ$ with integrated luminosity 500$fb^{-1}$ and $\sqrt{s}=$0.5, 1, 1.5 TeV energies. It is shown that the polarization can improve sensitivities by factors 2-3 depending on the energy.

description: We study the bifurcations of a set of nine nonlinear ordinary differential equations that describe the regulation of the cyclin-dependent kinase that triggers DNA synthesis and mitosis in the budding yeast, Saccharomyces cerevisiae. We show that Clb2-dependent kinase exhibits bistability (stable steady states of high or low kinase activity). The transition from low to high Clb2-dependent kinase activity is driven by transient activation of Cln2-dependent kinase, and the reverse transition is driven by transient activation of the Clb2 degradation machinery. We show that a four-variable model retains the main features of the nine-variable model. In a three-variable model exhibiting birhythmicity (two stable oscillatory states), we explore possible effects of extrinsic fluctuations on cell cycle progression.

description: We study the possibility of realising cosmic inflation, dark matter (DM), baryon asymmetry of the universe (BAU) and light neutrino masses in non-supersymmetric minimal gauged $B-L$ extension of the standard model with three right handed neutrinos. The singlet scalar field responsible for spontaneous breaking of $B-L$ gauge symmetry also plays the role of inflaton by virtue of its non-minimal coupling to gravity. While the lightest right handed neutrino is the DM candidate, being stabilised by an additional $Z_2$ symmetry, we show by performing a detailed renormalisation group evolution (RGE) improved study of inflationary dynamics that thermal DM is generally overproduced due to insufficient annihilations through gauge and scalar portals. This happens due to strict upper limits obtained on gauge and other dimensionless couplings responsible for DM annihilation while assuming the non-minimal coupling to gravity to be at most of order unity. The non-thermal DM scenario is viable, with or without $Z_2$ symmetry, although in such a case the $B-L$ gauge sector remains decoupled from the inflationary dynamics due to tiny couplings. We also show that the reheat temperature predicted by the model prefers non-thermal leptogenesis with hierarchical right handed neutrinos while being consistent with other requirements.

description: We study an electron transport property in two parallel quantum wires with random potentials. Assuming the same microscopic parameters for both wires, we focus on the relationship between inter-wire interaction and electron backward scattering by random potentials at low energy regime. Our analytical and numerical calculations show that the Drude weight, a measure of the electron transport, is influenced by inter-wire interaction and random potential independently, and little coupling between those two is observed, which is in contrast to a deep relationship between up- and down-spin interactions and random potentials in a single wire. It leads to that inter-wire interactions do not have a great influence on the Anderson localization in each wire.

description: We present a lattice QCD based determination of the chiral phase transition temperature in QCD with two massless (up and down) and one strange quark having its physical mass. We propose and calculate two novel estimators for the chiral transition temperature for several values of the light quark masses, corresponding to Goldstone pion masses in the range of $58~{\rm MeV}\lesssim m_π\lesssim 163~{\rm MeV}$. The chiral phase transition temperature is determined by extrapolating to vanishing pion mass using universal scaling analysis. After thermodynamic, continuum and chiral extrapolations we find the chiral phase transition temperature $T_c^0=132^{+3}_{-6}$ MeV. We also present some preliminary calculations on interplay of effective $U_A(1)$ restoration and chiral phase transition towards chiral limit.

description: Sign language recognition (SLR) is a challenging problem, involving complex manual features, i.e., hand gestures, and fine-grained non-manual features (NMFs), i.e., facial expression, mouth shapes, etc. Although manual features are dominant, non-manual features also play an important role in the expression of a sign word. Specifically, many sign words convey different meanings due to non-manual features, even though they share the same hand gestures. This ambiguity introduces great challenges in the recognition of sign words. To tackle the above issue, we propose a simple yet effective architecture called Global-local Enhancement Network (GLE-Net), including two mutually promoted streams towards different crucial aspects of SLR. Of the two streams, one captures the global contextual relationship, while the other stream captures the discriminative fine-grained cues. Moreover, due to the lack of datasets explicitly focusing on this kind of features, we introduce the first non-manual-features-aware isolated Chinese sign language dataset~(NMFs-CSL) with a total vocabulary size of 1,067 sign words in daily life. Extensive experiments on NMFs-CSL and SLR500 datasets demonstrate the effectiveness of our method.

Publisher: name: FID GEO
Year: 2020

description: The earthquake catalogue of southwestern Germany for the last millennium now contains about 30,000 digital macroseismic intensity data points (IDPs). Intensity assessments are based mainly on primary sources using the European Macroseismic Scale 1998 (EMS). The article describes a guideline for best practice of conventional macroseismic evaluation in application to historical and modern-time earthquakes in SW-Germany. Suitability of various diagnostics for intensity assessment is discussed. Assumptions to estimate damage grades and vulnerability classes of buildings are presented. Data restrictions and treatment of special cases are outlined. Further topics are quantification of uncertainties and IDP quality as well as substitutes for intensity. An essential task is to bridge the gap between information from historical sources and seismological needs for use in the earthquake catalogue, thus all issues have a focus on historical earthquakes. Questions of completeness, subjectivity, transparency, and interdisciplinary work are addressed also. Special emphasis is given to a well balanced use of the EMS scale throughout all time periods leading to consistent assessments in the catalogue.

title: The vocationalisation of the school curriculum: society, state and economy
Creators: name: Shilling, Chris
Publisher: name: The Open University
Year: 1988

description: This thesis is concerned with the vocationalisation of the school curriculum in Britain from the late nineteenth century to the present. It consists of three sections. The first section constitutes the major theoretical component of the work, and develops a view of society as a dialectically interrelating totality whose parts are invested with differential causal force. The social whole is seen as consisting of micro, meso and macrolevels, which correspond respectively to Inter-individual, interorganizational, and the social relationships which constitute the mode of production. This theory is then used to criticise certain existing approaches towards the sociology of education and develop an alternative which is utilised in the rest of my study. The second section examines the social and economic forces existing on micro, mesa and macro societal levels which were central to the formation and development of school-based vocational schemes. Here, I examine the relationships which have existed between individual career routes, the education system, state, economy, and class struggle. This facilitates an examination of the shifting determinations which constituted vocational education, as they have been located both diachronically and synchronically. The points of interconnection between the forces which impinged upon the progress of vocational education changed between the 'entrepreneurial' (late C19th to WW1), 'collective' (inter-War), and 'corporate' (post WW2) periods of education-industry relations. During these stages, a combination of factors reduced gradually the autonomy of the school system, served to increase the influence of the state over the curriculum, and enabled the introduction of a number of vocational schemes In the 'corporate' period. The final section moves between societal levels in a case-study analysis of the operation of two vocational schemes in a local education authority. This examines how the relationship between micro, meso and macro-levels can introduce disjunctions between the official aims and the actual consequences of vocational schemes. The case-study Is also used to refine elements of the earlier theory and identify the areas of autonomy which remain within micro and meso societal levels. The introduction of the Technical and Vocational Education Initiative, and the Schools Vocational Programme is traced, and their operation is examined. Here, I focus on the subject options process, a school-based vocational course, and the attitudes and approaches of Industrialists, teachers and students to work-experience.

description: As far as the member states of the European Union are concerned, it can be said that besides the declining proportion of agricultural workers, even the number of young farmers is constantly decreasing. In the strategy of Europe 2020: The intelligent, sustainable and inclusive growth, young agricultural growers are devoted a prominent role as taking the future of agriculture into consideration, this role is essential. In my research I am investigating the young smallholders of the southern region of the Great Hungarian Plain focusing on the young farmers of Homokhátság, as a significant section where there are agricultural properties of land of really poor quality. The farmers in Homokhátság dealing with fruit-and vine-growing or arable vegetable growing have tried to find the most suitable forms of agriculture. These characteristics cannot be found in other territories with poor fertility properties so Homokhátság can be considered as a good example. Having the results, I would like to find answers to questions like what motivated the young farmers to start dealing with agriculture, how they see their prospects for the future and what sorts of challenges they face in our age. According to the opinion of the young farmers, the new land law which came into force on 1st May 2014 did not have a positive influence on the chances of their getting a property of land. Due to the arable prices risen recently only farmers with more capital are able to buy properties. Cooperation is less popular among the youngsters and only some of the respondents were aware of the concept of machinery rings.

description: The aim of the paper was to present cluster organizations as a complementary structure in relation to clusters in the context of support that takes form of public intervention in the agri-food sector in Poland. In the process of integration of the Polish and the EU economic systems, cluster organizations have become a new element of the market. With the expansion of the cluster concept a blur has occurred with regard to the distinction of these two terms. Their proper perception is necessary if greater competitiveness is expected to take place in the agri-food sector that is a result of a planned and implemented cluster policy. In the literature as well as in business practice a wrong approach in which these two concepts are considered to be identical can be recognized. Consequently, public intervention is focused on supporting cluster organizations that are formed by only a fraction of entities operating in a cluster. The effects of such intervention are therefore limited to a small group of market participants.
The role of local governments in advancing energy efficiency for buildings : a British Columbia case study
Creators: name: Zeeg, Taylor
Publisher: name: University of British Columbia
Year: 2011

description: There is little doubt that local governments in Canada have a major role to play in addressing greenhouse gas emissions (GHGs). Considering about 50% of the nation's GHGs are under the direct or indirection influence or control of local governments, and the fact that local governments are well-positioned to reduce emissions through land use, energy and transportation planning, the question is not so much whether there is a role for municipalities but rather what ought that role be. The thesis draws on a Community Energy Management (CEM) conceptual framework in order to define the relationship between planning decisions and energy use. Following an analysis of buildings' energy use and associated greenhouse gas emissions, potential energy technologies and design practices that reduce buildings' secondary energy use and emissions are explored. Using British Columbia as a case study, this thesis explores the policy instruments available to local governments to advance effective energy efficiency related policies. Though local governments across Canada and beyond operate in distinct statutory environments, the case study aims to provide some general insight about how to improve the energy performance of buildings, and reduce emissions. From the case study I derive recommendations for all local governments and explore the policy implications of the findings. This thesis demonstrates there is a range of at-hand policy instruments local governments can readily utilize in order to realize the necessary conditions for a more energy efficient built environment.

description: In social processes, long-term trends can be influenced or disrupted by various factors, including public policy. When public policies depend on a misrepresentation of trends in the areas they are aimed at, they become random and disruptive, which can be interpreted as a source of disorder. Here we consider policies on the spatial organization of the French Higher Education and Research system, which reflects the authorities' hypothesis that scientific excellence is the prerogative of a few large urban agglomerations. By geographically identifying all the French publications listed in the Web of Science databases between 1999 and 2017, we highlight a spatial deconcentration trend, which has slowed down in recent years due to a freezed growth of the teaching force. This deconcentration continues, however, to sustain the growth of scientific production in small and medium-sized towns. An examination of the large conurbations shows the relative decline of sites that nevertheless have been highlighted as examples to be followed by the Excellence policies (Strasbourg among others). The number of students and faculty has grown less there, and it is a plaussible explanation for the relative decline in scientific production. We show that the publication output of a given site depends directly and strongly on the number of researchers hosted there. Based on precise data at the French level, our results confirm what is already known at world scale. In conclusion, we question the amount of disorder resulting from policies aligned with poorly assessed trends.
title: Trade unionism and socio-economic development in the Yorkshire glass industry, circa 1840-1940
Creators: name: Spencer, Terence
Publisher: name: The Open University
Year: 1988

description: This thesis examines the developmental pattern of trade unionism within the Yorkshire Glass Industry in the century after 1840. The concept of labour aristocracy is utilised to provide a framework for analysis of the actions and ideology of the artisan glassmakers both at the point of production and in a wider societal context. The thesis consists of two parts. Part, One, is a summary of the principal theories which have emerged from the controversy concerning the nature and role of the labour aristocracy and indicates areas of investigation concerning the position of the artisan glassworkers within the context of the ongoing debate. The nature of the principal sources employed together with the methodology utilised to form the overall analysis is discussed and ,a hypothesis is formulated. Part Two of the thesis consists of the analysis of data sources to test the hypothesis. The source material is examined within the context of three chronologically based sections. Each section corresponds to a discernable phase in trade union development within the Yorkshire Glass Industry. The three chronological sections are subdivided into an uneven series of topic headings each dealing with relevant aspects of the trade and trade unionism during the period under review. The arbitrary disruption of the time continuum in order to facilitate the handling of the source material has meant that some sub-topics are common to all three chronological periods whilst others are, perhaps, applicable to one or two only. Section one examines the years 1840 to 1880 which were years of trade union growth and the adoption and consolidation of centralised systems of union administration. The years 1880 to 1910 which form the second section were ones in which the unions under the adverse effects of trade depression, intensified competition both foreign and domestic, and the impact of technological change, suffered enforced retreat and retrenchment before experiencing a brief period of revival at the turn of the present century. The third section, 1910 - 1940, deals with the decline and demise of the craft-based unions in the face of the threat by automatic machine production processes and the adverse effects of the Great War and its economic aftermath.

Comment on the new $D_s^{(*)+} π^0$ resonances

description: We propose an explanation of the new resonances observed in $D_s^{(*)+} π^0$ decays. We suggest that the data can be explained by the mixing of conventional p-wave excited $D_s^+$ mesons with 4-quark states. The narrow states observed in $D_s^+ π^0$ and $D_s^{*+}π^0$ are primarily p-wave $D_{sJ}^{*}$ states, while the predominantly 4-quark states are shifted above $D^{(*)} K$ threshold and should be broad. Ranges for the mixing parameter and mass of the 4-quark state in this scenario are given. Other experimental consequences are discussed.

description: Algorithmic thinking is a central concept in the context of computational thinking, and it is commonly taught by computer programming. A recent trend is to introduce basic programming concepts already very early on at primary school level. There are, however, several challenges in teaching programming at this level: Schools and teachers are often neither equipped nor trained appropriately, and the best way to move from initial "unplugged" activities to creating programs on a computer are still a matter of open debate. In this paper, we describe our experience of a small INTERREG-project aiming at supporting local primary schools in introducing children to programming concepts using Ozobot robots. These robots have two distinct advantages: First, they can be programmed with and without computers, thus helping the transition from unplugged programming to programming with a computer. Second, they are small and easy to transport, even when used together with tablet computers. Although we learned in our outreach events that the use of Ozobots is not without challenges, our overall experience is positive and can hopefully support others in setting up first encounters with programming at primary schools.

description: By performing molecular dynamics simulations of binary Lennard-Jones systems with three different potentials, we show that increase of anharmonicity and capacity for intermolecular coupling of the potential is the cause of (i) the increase of kinetic fragility and nonexponentiality in the liquid state, (ii) the Tg-scaled temperature dependence of the nonergodicity parameter determined by the vibrations at low temperatures in the glassy state. Naturally these parameters correlate with each other, as observed experimentally by T. Scopigno et al., Science 302, 849 (2003).

Sie repräsentieren hinsichtlich Naturausstattung, Entwicklungstyp und Erhaltungszustand verschiedene Moortypen. Ergebnisse stratigraphischer, hydrologischer und vegetationskundlicher Untersuchungen werden vorgestellt. Aus der Kenntnis der Hydrologie der Niedermoore und ihrer Einzugsgebiete wurden Erhaltungs- und Wiedervernässungsmaßnahmen entwickelt. Die Auswirkungen der Wiedervemässungsmaßnahmen wurden untersucht, vor allem die Folgen für Wasserregime, Moorböden und Nutzung der Niedermoore.
description: Within the scope of a life-projekt several large fen areas, located in the Nature Reserve Nossentiner/ Schwinzer Heide, were investigated. They represent different types with respect to natural supply, type of development and state of preservation. The results of stratigraphical, hydrological and vegetational investigations are presented here. By knowledge of the hydrology of the fens and their surrounding areas conservation and rewetting measures have been developed. The effects of rewetting measures were investigated, especially consequences for the hydrological regime, fen soils and the land use of the fen areas as a whole.

description: Intelligent reflecting surfaces (IRSs) are envisioned to provide reconfigurable wireless environments for future communication networks. In this paper, both downlink and uplink IRS-aided non-orthogonal multiple access (NOMA) and orthogonal multiple access (OMA) networks are studied, in which an IRS is deployed to enhance the coverage by assisting a cell-edge user device (UD) to communicate with the base station (BS). To characterize system performance, new channel statistics of the BS-IRS-UD link with Nakagami-$m$ fading are investigated. For each scenario, the closed-form expressions for the outage probability and ergodic rate are derived. To gain further insight, the diversity order and high signal-to-noise ratio (SNR) slope for each scenario are obtained according to asymptotic approximations in the high-SNR regime. It is demonstrated that the diversity order is affected by the number of IRS reflecting elements and Nakagami fading parameters, but the high-SNR slope is not related to these parameters. Simulation results validate our analysis and reveal the superiority of the IRS over the full-duplex decode-and-forward relay.
