description: We present a semi-analytical method for the calculation of coherent Askaryan radiation in showers induced by neutrinos of any flavor in ice. We compare our results with those of a full Monte Carlo simulation based on the ZHAireS code. This approach is able to reproduce the vector potential and hence electric field at any experimentally relevant observer position in the time domain. This work extends published results only valid for electron-induced showers. We establish the validity of the semi-analytical calculation of the radio signal produced by all types of neutrino-induced showers in ice. The method is computationally efficient and only requires as inputs the longitudinal charge excess profile of the showers and a parameterization of the vector potential in the far-field region of the shower at the Cherenkov angle that we also provide. Our methodology avoids tracking the contributions to the electric field from millions of particles every time the radio pulse has to be calculated at a given observer position. These results can be readily used in the interpretation of the data taken by experiments, and in the planning and design of future initiatives based on the radio technique in ice.

description: We consider some classes of solutions of the static, spherically symmetric gravitational field equations in the vacuum in the brane world scenario, in which our Universe is a three-brane embedded in a higher dimensional space-time. The vacuum field equations on the brane are reduced to a system of two ordinary differential equations, which describe all the geometric properties of the vacuum as functions of the dark pressure and dark radiation terms (the projections of the Weyl curvature of the bulk, generating non-local brane stresses). Several classes of exact solutions of the vacuum gravitational field equations on the brane are derived. In the particular case of a vanishing dark pressure the integration of the field equations can be reduced to the integration of an Abel type equation. A perturbative procedure, based on the iterative solution of an integral equation, is also developed for this case. Brane vacuums with particular symmetries are investigated by using Lie group techniques. In the case of a static vacuum brane admitting a one-parameter group of conformal motions the exact solution of the field equations can be found, with the functional form of the dark radiation and pressure terms uniquely fixed by the symmetry. The requirement of the invariance of the field equations with respect to the quasi-homologous group of transformations also imposes a unique, linear proportionality relation between the dark energy and dark pressure. A homology theorem for the static, spherically symmetric gravitational field equations in the vacuum on the brane is also proven.

Null energy conditions outside a background potential

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study the Casimir energy of a minimally coupled, real, massless scalar field outside a spherically symmetric background potential. We obtain a general expression for the null energy condition in d dimensions and explicit expressions for a perfectly reflecting spherical boundary in 3+1 and 2+1 dimensions. In these cases, the null energy condition is always violated for radial motion and obeyed for azimuthal motion. Nevertheless, the averaged null energy condition is always obeyed.

description: Inspired by the idea of blurring the exponential function, we define blurred variants of the $j$-function and its derivatives, where blurring is given by the action of a subgroup of $\rm{GL}_2(\mathbb{C})$. For a dense subgroup (in the complex topology) we prove an Existential Closedness theorem which states that all systems of equations in terms of the corresponding blurred $j$ with derivatives have complex solutions, except where there is a functional transcendence reason why they should not. For the $j$-function without derivatives we prove a stronger theorem, namely, Existential Closedness for $j$ blurred by the action of a subgroup which is dense in $\rm{GL}_2^+(\mathbb{R})$, but not necessarily in $\rm{GL}_2(\mathbb{C})$. We also show that for a suitably chosen countable algebraically closed subfield $C \subseteq \mathbb{C}$, the complex field augmented with a predicate for the blurring of the $j$-function by $\rm{GL}_2(C)$ is model theoretically tame, in particular, $ω$-stable and quasiminimal.

description: Spin-orbit interaction and structure inversion asymmetry in combination with magnetic ordering is a promising route to novel materials with highly mobile spin-polarized carriers at the surface. Spin-resolved measurements of the photoemission current from the Si-terminated surface of the antiferromagnet TbRh2Si2 and their analysis within an ab initio one-step theory unveil an unusual triple winding of the electron spin along the fourfold-symmetric constant energy contours of the surface states. A two-band k.p model is presented that yields the triple winding as a cubic Rashba effect. The curious in-plane spin-momentum locking is remarkably robust and remains intact across a paramagnetic-antiferromagnetic transition in spite of spin-orbit interaction on Rh atoms being considerably weaker than the out-of-plane exchange field due to the Tb 4f moments.

Electromagnetic radiation (EMR) and its interpretation in terms of stresses in the lithosphere

description: Electromagnetic radiation (EMR) as measured at the surface of the lithosphere or underground shows preferred orientations, which can be related to microcracks and other brittle structures at micro and nano scales (see Bahat et al. 2005 and references therein). During the last years, numerous studies showed the applicability of EMR measurements for the determination of active fractures and stress orientations. EMR is determined with a ‘Cerescope’, which picks up EMR signals at frequencies from 5– 50 kHz (Obermeyer, 2005) with a ferrite aerial and processes them electronically so that the results can be displayed on a screen or copied to a computer. With the help of oriented EMR measurements, intensity variations are determined, which can be related to preferred crack fracture orientations. From this information, orientations of the principal stresses can be calculated. In addition, the intensity of the EMR is related to stress magnitudes...

description: In spite of the fact that there are different techniques in the creation of the high-quality liquid crystals (LCs) alignment by means of various surfaces, the azimuthal and polar anchoring energies as well as the pre-tilt angle are important parameters to all of them. Here, the modified by a certain manner aligning layers, previously formed by nonlinear laser lithography (NLL), having high-quality nano-periodic grooves on Ti surfaces, recently proposed for LC alignment was studied. The change of the scanning speed of NLL in the process of nano-structured Ti surfaces and their further modification by means of ITO-coating, and deposition of polyimide film has enabled different aligning layers, whose main characteristics, namely azimuthal and polar anchoring energies, were measured. For the modified aligning layers, the dependencies of the twist and pre-tilt angles for LC cells filled by nematic E7 (Δε > 0) and MLC-6609 (Δε < 0) were obtained. Also the contact angle for droplets of isotropic liquid (glycerol), and nematic LCs was measured for the various values of the scanning speed during the laser processing.

description: We study the stress tensor multiplet four-point function in the 6d maximally supersymmetric $(2,0)$ $A_{N-1}$ and $D_N$ theories, which have no Lagrangian description, but in the large $N$ limit are holographically dual to weakly coupled M-theory on $AdS_7\times S^4$ and $AdS_7\times S^4/\mathbb{Z}_2$, respectively. We use the analytic bootstrap to compute the 1-loop correction to this holographic correlator coming from Witten diagrams with supergravity $R$ and the first higher derivative correction $R^4$ vertices, which is the first 1-loop correction computed for a non-Lagrangian theory. We then take the flat space limit and find precise agreement with the corresponding terms in the 11d M-theory S-matrix, some of which we compute for the first time using two-particle unitarity cuts.

description: Excerpts from the report: The equations and related information presented in this report are helpful to the cotton trade and textile industry in choosing cottons best suited to the manufacture of specific products, in selecting various blends of cotton for processing, and for meeting different levels of product quality. Such equations and knowledge, moreover, give assistance to cotton breeders by informing them of the fiber properties they should consider important in their programs. This report presents a number of new equations for predicting the strength and appearance of any size of carded yarn over a wide range, number of neps per 100 sq. in. of card web, and percentage of total picker and card waste on the basis of improved methods for evaluating raw-cotton quality. Predicting equations including only the several most important factors to each of those dependent variables, however, are recommended. These equations are adapted to the general run of American upland cottons in current commercial production.

description: Collisions of twisted particles --- that is, non-plane-wave states of photons, electrons, or any other particle, equipped with a non-zero orbital angular momentum (OAM) with respect to its propagation direction --- offer novel ways to probe particle structure and interactions. In the recent paper \cite{Ivanov:2019vxe}, we argued that resonance production in twisted photon collisions or twisted $e^+e^-$ annihilation gives access to parity- and spin-sensitive observables in inclusive cross sections, even when the initial particles are unpolarized. Here, we explore these features in detail, providing a qualitative picture and illustrating it with numerical examples. We show how one can detect parity-violating effects in collisions of unpolarized twisted photons and how one can produce almost $100\%$ polarized vector mesons in unpolarized twisted $e^+e^-$ annihilation. These examples highlight the unprecedented level of control over polarization offered by twisted particles, impossible in the usual plane wave collisions.

title: The Relationship between Liberalism and Conservatism: Competitive, Symbiotic or Parasitic?
Creators: name: Bousfield, Ann
Publisher: name: The Open University
Year: 2002

description: The thesis argues that the relationship between liberalism and conservatism is closer than is commonly supposed. Though the 'triumph of liberalism' - whether intellectual or political - is a commonplace it in fact rests on a conceit: liberalism's claim to be able to provide a publicly justified morality founded on the ideas of rationality, tolerance and autonomy. That is the root of, to quote MacIntyre, 'the spectre haunting contemporary liberal theorists [which] is not communitarianism, but their own irrelevance'. I shall argue that this irrelevance is neither the result of liberal theorists' inadequacies nor a corollary of the exigencies of contemporary politics. Rather, it is a structural inevitability. For liberalism can justify its values only by resorting to a conservative axiology. The thesis delineates three strands of liberalism, classical liberalism, libertarianism and perfectionism. I argue that the problem that all these liberalisms have in common is that they all need to use a conservative form of argument to justify liberal norms of rationality, autonomy and tolerance. The origin of this dilemma lies in the nature of liberalism itself. Since liberalism's emergence as a self-conscious form of political discourse it has been founded on a particular view of how people are. Liberal doctrines about the social and political obligations of individuals are derived from the view of man (sic) as a rational choosing individual. However, such individuals are historical artefacts and their flourishing depends on a precise set of historical circumstances. I argue, therefore, that the various species of liberalism examined in this thesis all advocate - to a greater or lesser extent - conservative political prescriptions in defence of the matrix of institutions, laws, manners and mores which allow liberal individuality to flourish.

description: In this work we present a multi-modal machine learning-based system, which we call ACORN, to analyze videos of school classrooms for the Positive Climate (PC) and Negative Climate (NC) dimensions of the CLASS observation protocol that is widely used in educational research. ACORN uses convolutional neural networks to analyze spectral audio features, the faces of teachers and students, and the pixels of each image frame, and then integrates this information over time using Temporal Convolutional Networks. The audiovisual ACORN's PC and NC predictions have Pearson correlations of $0.55$ and $0.63$ with ground-truth scores provided by expert CLASS coders on the UVA Toddler dataset (cross-validation on $n=300$ 15-min video segments), and a purely auditory ACORN predicts PC and NC with correlations of $0.36$ and $0.41$ on the MET dataset (test set of $n=2000$ videos segments). These numbers are similar to inter-coder reliability of human coders. Finally, using Graph Convolutional Networks we make early strides (AUC=$0.70$) toward predicting the specific moments (45-90sec clips) when the PC is particularly weak/strong. Our findings inform the design of automatic classroom observation and also more general video activity recognition and summary recognition systems.

description: Spherical plasma lens models are known to suffer from a severe over-pressure problem, with some observations requiring lenses with central pressures up to millions of times in excess of the ambient ISM. There are two ways that lens models can solve the over-pressure problem: a confinement mechanism exists to counter the internal pressure of the lens, or the lens has a unique geometry, such that the projected column-density appears large to an observer. This occurs with highly asymmetric models, such as edge-on sheets or filaments, with potentially low volume-density. In the first part of this work we investigate the ability of non-magnetized plasma filaments to mimic the magnification of sources seen behind spherical lenses and we extend a theorem from gravitational lens studies regarding this model degeneracy. We find that for plasma lenses, the theorem produces unphysical charge density distributions. In the second part of the work, we consider the plasma lens over-pressure problem. Using magnetohydrodynamics, we develop a non self-gravitating model filament confined by a helical magnetic field. We use toy models in the force-free limit to illustrate novel lensing properties. Generally, magnetized filaments may act as lenses in any orientation with respect to the observer, with the most high density events produced from filaments with axes near the line of sight. We focus on filaments that are perpendicular to the line of sight that show the toroidal magnetic field component may be observed via the lens rotation measure.

description: Some aspects of the predictability problem in dynamical systems are reviewed. The deep relation among Lyapunov exponents, Kolmogorov-Sinai entropy, Shannon entropy and algorithmic complexity is discussed. In particular, we emphasize how a characterization of the unpredictability of a system gives a measure of its complexity. A special attention is devoted to finite-resolution effects on predictability, which can be accounted with suitable generalization of the standard indicators. The problems involved in systems with intrinsic randomness is discussed, with emphasis on the important problems of distinguishing chaos from noise and of modeling the system.

The merchandising experiment was conducted during an 8-week period in 12 retail food stores. The research indicated that under comparable conditions, sales of Cheddar cheese may be stimulated by: (1) Providing consumers with an opportunity to purchase both in-store packaged and prepackaged cheese; (2) making cheese available to consumers in packages varying in weights up to 2 pounds, but restricting the larger packages to perhaps 15 percent of the total number of packages displayed; and (3) allocating, in most instances, slightly more display space to sharp cheese than to mild cheese.

description: Computability logic is a formal theory of (interactive) computability in the same sense as classical logic is a formal theory of truth. This approach was initiated very recently in "Introduction to computability logic" (Annals of Pure and Applied Logic 123 (2003), pp.1-99). The present paper reintroduces computability logic in a more compact and less technical way. It is written in a semitutorial style with a general computer science, logic or mathematics audience in mind. An Internet source on the subject is available at http://www.cis.upenn.edu/~giorgi/cl.html, and additional material at http://www.csc.villanova.edu/~japaridz/CL/gsoll.html .

 Cylindroiulus (Phalloiulus) rifanus Schubart 1960: 184.
No specimens of this species were available for examination but the illustrations of the gonopods and the original description by Schubart are good and show that this species is clearly different to any of those above. For the sake of completeness, a brief description is provided here.
 Locality. Morocco: Southern Chauen, Rif.
 Descriptiυe notes. Body length 24 mm („) to 25 mm (♀). Diameter 1.9 mm („) to 2.2 mm (♀); number of body rings 53 („) to 56 (♀).
 Telson. Not described. Anal valves with five to seven pairs of setae.
 Male gonopods (Figures 26, 27). The promerite, mesomerite and flagellum do not appear of particular note. The paracoxal rim seems high. The solenomere and brachite appear separate, but linked. There seem to be at least two other projections from the posterior gonopods that might be synonymous with those termed here X and Y. The anterior view of the posterior gonopods seems to be the clearest for separating this from the other species described here.

description: Recent developments in superstring theory and noncommutative geometry are deeply related to the idea of Eguchi-Kawai reduction in large N gauge theories which dates back to early 80s. After a general review on this subject including revived interests in solving planar QCD, we present some results in the superstring matrix model suggesting the dynamical generation of 4d space-time due to the collapse of the eigenvalue distribution. We then discuss interesting dynamical properties of field theories in noncommutative geometry, which have been revealed by Monte Carlo simulations of twisted reduced models. We conclude with a comment on the recent proposal for a lattice construction of supersymmetric gauge theories based on reduced models.

description: Die Schreibkompetenz ist nicht nur ein wichtiger Bestandteil im Deutschunterricht, sondern auch elementar für die spätere berufliche Ausbildung und den Alltag eines jeden Kindes. Doch immer wieder haben Schülerinnen und Schüler – ob mit oder ohne Migrationshintergrund – gerade mit der Schreibkompetenz Probleme in der Schule. Speziell Kinder mit Migrationshintergrund weisen zudem häufig noch einen kleinen Wortschatz auf und haben Probleme mit der deutschen Syntax. Diese Masterarbeit geht der Frage nach, wie Viertklässler mit besonderem Förderbedarf im Bereich Schreiben gefördert werden können. Abgestützt auf den theoretischen Grundlagen in den Bereichen Schreibkompetenz, Schreibförderung und Deutsch als Zweitsprache wurde ein Konzept zur Förderung der Schreibkompetenz entwickelt. Dabei lag der Fokus auf dem Vermitteln von Schreibstrategien, einem Wortschatztraining und der Auseinandersetzung mit der deutschen Syntax durch das Schreiben mehrerer Bildergeschichten. Als Unterrichtsform wurde die Methode der direkten Instruktion angewendet. Das Konzept wurde in drei vierten Klassen durchgeführt und mit Hilfe der qualitativen Inhaltsanalyse, einem normierten Wortschatztest und einem eigens dafür entwickelten Textbeurteilungsraster evaluiert.

description: O objetivo deste estudo visa compreender o processo e desenvolvimento das obras de Rafael Moneo sob dois aspectos: o do tempo intrínseco e do tempo extrínseco a fim de encontrar dois projetos que justifiquem esse entendimento de modo a estabelecer um comparativo entre diferentes formas de aplicação desses aspectos. Para tal, primeiramente, propomos entender a relação do tempo e da arquitetura associada ao conceito de pré-existência e, assim, compreender para onde e como se dá o próprio processo de desenvolvimento projetual de acordo com o sítio. Por meio de bibliografias que relacionem a disciplina arquitetônica a ideia do tempo já desenvolvidos por William Curtis, Josep Quetglas, Ignasi de Solá-Morales e, do próprio Rafael Moneo, buscamos ir além da questão teórica trabalhada pelos autores no que diz respeito aos conceitos do tempo, mas sim, buscar nos projetos de Moneo, a aplicação desses diferentes modos de diálogo com o lugar a partir de um condicionante interno ou externo. Ao longo do desenvolvimento do estudo foram encontrados projetos e escritos que contribuem para a escolha de dois projetos para análise prática a partir de um entendimento teórico - o Museu de Arte Romana (1986) e a Ampliação da Prefeitura de Múrcia (1998). Os dois exemplos buscam retratar diferentes tipos de relação com o tempo, o primeiro, sendo concebido a partir de condições intrínsecas do lugar e, o segundo, a partir de condições extrínsecas. Como se dão as relações com os tempos pré-existentes nos projetos de Rafael Moneo? Até que ponto essa pré- existência se torna fator determinante no processo de concepção e tradução em arquitetura?

title: The concept of function in osteopathy and conventional medicine : a comparative study
Creators: name: Tyreman, Stephen John
Publisher: name: The Open University
Year: 2001

description: This study compares and contrasts the uses of 'function' in osteopathy and in a closely related area of conventional medicine, viz., orthopaedic surgery. Function is a fundamental concept in both; but a survey of the literature, and an initial analysis of the language used by practitioners in a sample of case studies, suggests that while orthopaedic surgeons focus on local failures of physiological function (Fphys), osteopaths are concerned with such failures in the global context of the whole body (Fglob). This is closely related to individual patients' expectations in relation to their overall ability to function (Fpt). The musculo-skeletal system, with which osteopaths are expert, is shown to be particularly significant for understanding Fphys, Fpt and Fglob. These uses of function are further analysed by drawing on the philosophical literature. This is shown to focus, like orthopaedic surgeons, mainly on biological function (Fbiol which includes Fphys). In consequence, it is argued, the philosophical literature has under-emphasised the significance of context in defining functional norms. Certain authors have recognised the importance of context for the functioning of people (i. e. as Fpt); in this thesis, by contrast, context is shown to be important in defining functional norms at all levels, including the physiological/biological. In respect of the relationship between osteopathy and conventional medicine, it is concluded that Fglob (as employed more by osteopaths) involves explaining the clinical significance of local dysfunction in the broad context of patients' activities, and Fphys (as employed more by orthopaedic surgeons) involves categorising local dysfunction in terms of referential standards. The concept of agency, although not examined in detail, emerges as the key to linking the role of context in the meaning of function statements to the intentions and self-perception of patients in clinical practice. Because of the special role of the musculo-skeletal system in enacting agency, osteopathy offers particular insights into the contextual nature of function statements.

description: Experience shows that semiconductor switches in power electronics systems are the most vulnerable components. One of the most common ways to solve this reliability challenge is component-level redundant design. There are four possible configurations for the redundant design in component-level. This paper presents a comparative reliability analysis between different component-level redundant designs for solid state fault current limiter (SSFCL). The aim of the proposed analysis is to determine the more reliable component-level redundant configuration. The mean time to failure (MTTF) is used as the reliability parameter. Considering both fault types (open circuit and short circuit), the MTTFs of different configurations are calculated. It is demonstrated that more reliable configuration depends on the junction temperature of the semiconductor switches in the steady state. That junction temperature is a function of i) ambient temperature, ii) power loss of the semiconductor switch and iii) thermal resistance of heat sink. Also, results sensitivity to each parameter is investigated. The results show that in different conditions, various configurations have higher reliability. The experimental results are presented to clarify the theory and feasibility of the proposed approaches. At last, levelized costs of different configurations are analyzed for a fair comparison.

description: Galaxy clusters are the most massive collapsed structures in the universe whose potential wells are filled with hot, X-ray emitting intracluster medium. Observations however show that a significant number of clusters (the so-called cool-core clusters) also contain large amounts of cold gas in their centres, some of which is in the form of spatially extended filaments spanning scales of tens of kiloparsecs. These findings have raised questions about the origin of the cold gas, as well as its relationship with the central active galactic nucleus (AGN), whose feedback has been established as a ubiquitous feature in such galaxy clusters. Here we report a radiation hydrodynamic simulation of AGN feedback in a galaxy cluster, in which cold filaments form from the warm, AGN-driven outflows with temperatures between $10^4$ and $10^7$ K as they rise in the cluster core. Our analysis reveals a new mechanism, which, through the combination of radiative cooling and ram pressure, naturally promotes outflows whose cooling time is shorter than their rising time, giving birth to spatially extended cold gas filaments. Our results strongly suggest that the formation of cold gas and AGN feedback in galaxy clusters are inextricably linked and shed light on how AGN feedback couples to the intracluster medium.

Speeding up dynamics by tuning the non-commensurate size of rod-like particles in a smectic phase

description: Using simulations, we study the diffusion of rod-like guest particles in a smectic environment of rod-like host particles. We find that the dynamics of guest rods across smectic layers changes from a fast nematic-like diffusion to a slow hopping-type dynamics via an intermediate switching regime by varying the length of the guest rods with respect to the smectic layer spacing. We determine the optimal rod length that yields the fastest and the slowest diffusion in a lamellar environment. We show that this behavior can be rationalized by a complex 1D effective periodic potential exhibiting two energy barriers, resulting in a varying preferred mean position of the guest particle in the smectic layer. The interplay of these two barriers controls the dynamics of the guest particles yielding a slow, an intermediate and a fast diffusion regime depending on the particle length.

description: An implementation of the Reverse Monte Carlo algorithm is presented for the study of amorphous tetrahedral semiconductors. By taking into account a number of constraints that describe the tetrahedral bonding geometry along with the radial distribution function, we construct a model of amorphous silicon using the reverse monte carlo technique. Starting from a completely random configuration, we generate a model of amorphous silicon containing 500 atoms closely reproducing the experimental static structure factor and bond angle distribution and in improved agreement with electronic properties. Comparison is made to existing Reverse Monte Carlo models, and the importance of suitable constraints beside experimental data is stressed.
