description: Unter Verwendung holographischer Methoden rechnen wir die Zweipunkt- Korrelationsfunktion und die Entanglement Entropie für Schwerionen-Kollisionen aus, welche als Kollision von Gravitationsschockwellen in 5 dimensionaler Anti-de Sitter Raumzeit modelliert werden. Die Berechnung dieser Größen reduziert sich auf der Seite der Gravitationstheorie auf die Berechnung extremaler Flächen (bzw. Geodäten, unter Verwendung der Symmetrie der untersuchten Region). Im Rahmen dieser Arbeit wurde ein Mathematica Package entwickelt, das diese Berechnungen mittels Relaxationsmethoden für verschiedene Szenarios ausführen kann. Unter Verwendung zweier verschiedener Anfangsbedingungen, breiten und schmalen Schockwellen, zeigt sich qualitativ unterschiedliches Verhalten der berechneten Größen. Das erlaubt es, die Entanglement Entropie als Ordnungsparameter für die Unterscheidung zwischen Transparenz und vollem Abstoppen der kollidierenden Schockwellen zu verwenden.
description: Using the methods of holography we calculate the two-point function and entanglement entropy in heavy ion collisions, modeled by colliding gravitational shock waves in Anti-de Sitter spacetime. The calculation reduces to finding extremal surfaces (or geodesics, using the symmetry of the investigated boundary region) in the gravitational problem. A Mathematica package, capable of finding geodesics for several different scenarios using relaxation methods, was developed as part of this work. Using two different initial conditions, wide and narrow shock waves, we find qualitatively different behavior of the calculated quantities. This allows to use the entanglement entropy as order parameter to distinguish between the transparency and full stopping scenario of colliding shock waves.

Ancient Egypt

description: Issue 27 comprises two articles focusing on the collection of ancient Egyptian artefacts at the British Museum. The first one publishes for the first time a group of mummy bandages inscribed with the Liturgy of Opening the Mouth for Breathing. This text is only known from a few other sources, and none on bandages. This study introduces the text written on these unique documents, as well as their owner, a man named Hor. It also investigates the possibly close relationship between these documents and the other versions of this text. The second article delves into the acquisition by the British Museum in 1823 of the first collection of antiquities formed by Henry Salt (1780-1827), British Consul in Egypt. This extensive ensemble of objects and mummies was crucial in shaping the Museum’s Egyptian collection, which until then had been relatively small. This article publishes for the first time in their entirety many of the archival documents relating to this acquisition, including a list of the main objects drafted by Salt, with commentary and identifications of items in the collection, as far as these are possible. This paper aims at making these documents available in the hope that future research will build on this information.

description: The paper contains the analysis of an introductory survey results carried out among organic farmers in Lower Silesia and in nine randomly selected voivodeships outside the region in 2008 and 2009. Thanks to the research, the key factors influencing organic farming were identified. It was revealed that there were such opportunities for organic food market as production profitability, potential growth of sales, EU agri-environmental subsidies and farmers’ optimistic predictions of demand growth. The barriers for organic farming development are high production costs, difficulties connected with bureaucratic procedures as well as the underdeveloped distribution system. It was stated that on the supply side there were meaningful opportunities of further development of organic food market but it was conditioned by an intensification of public measures connected with the institutional and financial support such as increasing of the subsidies, simplification of administrative procedures and stimulation of distribution system development. / Synopsis. W artykule przedstawiono wyniki badań ankietowych przeprowadzonych dwukrotnie w 2008 i 2009 roku wśród rolników prowadzących gospodarstwa ekologiczne na Dolnym Śląsku oraz w dziewięciu losowo wybranych województwach w innych regionach. Zidentyfikowano istotne czynniki stanowiące szanse rozwoju rolnictwa ekologicznego, takie jak opłacalność produkcji, rosnące możliwości sprzedaży, możliwość uzyskiwania dotacji UE i korzystne przewidywania rolników odnośnie przyszłych zmian popytu w Polsce. Po stronie barier zwrócono uwagę na wysokie koszty produkcji, trudności związane z biurokratycznymi procedurami administracyjnymi oraz niewystarczające możliwości dotarcia do konsumentów, wynikające ze słabo rozwiniętego systemu dystrybucji. Stwierdzono, że po stronie podaży istnieją korzystne perspektywy rozwoju rynku żywności ekologicznej, jednak należałoby usprawnić politykę wsparcia producentów poprzez podniesienie stawek dotacji, uproszczenie wymogów proceduralno-administracyjnych oraz stymulowanie rozwoju systemu dystrybucji.

description: Within an advanced Langevin-hydrodynamics framework coupled to a hybrid fragmentation-coalescence hadronization model, we study heavy flavor quenching and flow in relativistic heavy-ion collisions. We investigate how the initial heavy quark spectrum, the energy loss and hadronization mechanisms of heavy quarks in medium, the evolution profile of pre-equilibrium stage, the flow of medium and the temperature dependence of heavy quark diffusion coefficient influence the suppression and elliptic flow of heavy mesons at RHIC and the LHC. Our result shows that different modeling of initial conditions, pre-equilibrium evolution and in-medium interaction can individually yield about 10-40% uncertainties in D meson suppression and flow at low transverse momentum. We also find that a proper combination of collisional versus radiative energy loss, coalescence versus fragmentation in hadronization, and the inclusion of medium flow are the most important factors for describing the suppression and elliptic flow of heavy mesons.

description: Measuring the amplitude and the absolute phase of a monochromatic microwave field at a specific point of space and time has many potential applications, including precise qubit rotations and wavelength quantum teleportation. Here we show how such a measurement can indeed be made using resonant atomic probes, via detection of incoherent fluorescence induced by a laser beam. This measurement is possible due to self-interference effects between the positive and negative frequency components of the field. In effect, the small cluster of atoms here act as a highly localized pick-up coil, and the fluorescence channel acts as a transmission line.

description: The Barker-Henderson perturbation theory is a bedrock of liquid-state physics, providing quantitative predictions for the bulk thermodynamic properties of realistic model systems. However, this successful method has not been exploited for the study of inhomogeneous systems. We develop and implement a first-principles 'Barker-Henderson density functional', thus providing a robust and quantitatively accurate theory for classical fluids in external fields. Numerical results are presented for the hard-core Yukawa model in three dimensions. Our predictions for the density around a fixed test particle and between planar walls are in very good agreement with simulation data. The density profiles for the free liquid vapour interface show the expected oscillatory decay into the bulk liquid as the temperature is reduced towards the triple point, but with an amplitude much smaller than that predicted by the standard mean-field density functional.

description: It is shown that harmonic functions from a simply connected domain in R^3 to R^3 cannot always be expressed as a sum of a monogenic (hyperholomorphic) function and an antimonogenic function, in contrast to the situation for complex numbers or quaternions. Harmonic functions orthogonal in L_2 to all such sums are termed "contragenic" and their properties are studied. A "Bergman kernel" and is derived, whose corresponding operator vanishes precisely on the contragenic functions. A graded orthonormal basis for the contragenic function in the ball B^3 is given.

description: We investigate the practice of assigning high spin temperatures to damped Lyman-alpha absorption systems (DLAs) not detected in HI 21-cm absorption. In particular, Kanekar & Chengaulr (2003) have attributed the mix of 21-cm detections and non-detections in low redshift (z<2.04) DLAs to a mix of spin temperatures, while the non-detections at high redshift were attributed to high spin temperatures. Below z=0.9, where some of the DLA host galaxy morphologies are known, we find that 21-cm absorption is normally detected towards large radio sources when the absorber is known to be associated with a large intermediate (spiral) galaxy. Furthermore, at these redshifts, only one of the six 21-cm non-detections has an optical identification and these DLAs tend to lie along the sight-lines to the largest background radio continuum sources. For these and many of the high redshift DLAs occulting large radio continua, we therefore expect covering factors of less than the assumed/estimated value of unity. This would have the effect of introducing a range of spin temperatures considerably narrower than the current range of >9000 K, while still supporting the hypothesis that the high redshift DLA sample comprises a larger proportion of compact galaxies than the low redshift sample.

title: Combinatorial aspects of root lattices and words
Creators: name: Heuer, Manuela
Publisher: name: The Open University
Year: 2010

description: This thesis is concerned with two topics that are of interest for the theory of aperiodic order. In the first part, the similar sublattices and coincidence site lattices of the root lattice A4 are analysed by means of a particular quaternion algebra. Dirichlet series generating functions are derived, which count the number of similar sublattices, respectively coincidence site lattices, of each index. In the second part, several strategies to derive upper and lower bounds for the entropy of certain sets of powerfree words are presented. In particular, Kolpakov's arguments for the derivation of lower bounds for the entropy of powerfree words are generalised. For several explicit sets we derive very good upper and lower bounds for their entropy. Notably, Kolpakov's lower bounds for the entropy of ternary squarefree, binary cubefree and ternary minimally repetitive words are confirmed exactly.

description: We have studied the cosmological evolution of domain wall networks in two, three and four spatial dimensions using high-resolution field theory simulations. The dynamical range and number of our simulations is larger than in previous works, but does not allow us to exclude previous hints of deviations to the naively expected scale-invariant evolution. These results therefore suggest that the approach of domain wall networks to linear scaling is a much slower process than that of cosmic strings, which has been previously characterized in detail.

description: The paper presents diagnosis of incomes in different types of households in the regions of Poland. The study was based on desk research method. Basic data come from the Central Statistical Office (GUS) from the publication Household budgets in the years 2009-2012. Analysis of the data confirmed the differentiation between the amount of income, available income and disposable income per one household member in different regions of Poland, and between urban and rural residents. Revenues in the provinces of lubelskie, opolskie, podlaskie and świętokrzyskie increased whereas the revenues in the kujawsko-pomorskie and warmińsko-mazurskie declined. The biggest increase in households available income occurred in cities with less than 20 thousands residents (9.3%). It resulted mainly from an increase in all social benefits. An increase in revenues in regions widely recognized as poor should be regarded as a positive trend.
Geometric approach to fragile topology beyond symmetry indicators

description: We present a framework to systematically address topological phases when finer partitionings of bands are taken into account, rather than only considering the two subspaces spanned by valence and conduction bands. Focusing on $C_2\mathcal{T}$-symmetric systems that have gained recent attention, for example in the context of layered van-der-Waals graphene heterostructures, we relate these insights to homotopy groups of Grassmannians and flag varieties, which in turn correspond to cohomology classes and Wilson-flow approaches. We furthermore make use of a geometric construction, the so-called Plücker embedding, to induce windings in the band structure necessary to facilitate non-trivial topology. Specifically, this directly relates to the parametrization of the Grassmannian, which describes partitioning of an arbitrary band structure and is embedded in a better manageable exterior product space. From a physical perspective, our construction encapsulates and elucidates the concepts of fragile topological phases beyond symmetry indicators as well as non-Abelian reciprocal braiding of band nodes that arises when the multiple gaps are taken into account. The adopted geometric viewpoint most importantly culminates in a direct and easily implementable method to construct model Hamiltonians to study such phases, constituting a versatile theoretical tool.

It has been found that with the increase in farm size increased the percentage of farmers who declared the use of banking services and products, and in the majority of them (over 80% of respondents) used the services of only one bank. The analysis also showed that of banking services and products likely to use farmers with secondary or higher education.
title: A framework for understanding user interaction with content-based image retrieval: model, interface and users
Creators: name: Liu, Haiming
Publisher: name: The Open University
Year: 2010

description: User interaction is essential to the communication between users and content-based image retrieval (CBIR) systems. User interaction covers three key elements: an interaction model, an interactive interface and users. The three key elements combine to enable effective interaction to happen. Many studies have investigated different aspects of user interaction. However, there is lack of research in combining all three elements in an integrated manner, especially through well-principled data analysis based on a systematic user study. In this thesis, we investigate the combination of all three elements for interactive CBIR. We first propose uInteract - a framework including a novel four-factor user interaction model (FFUIM) and an interactive interface. The FFUIM aims to improve interaction and search accuracy of the relevance feedback mechanism for CBIR. The interface delivers the FFUIM visually, aiming to support users in grasping how the interaction model functions and how best to manipulate it. The framework is tested in three task-based and user-oriented comparative evaluations, which involves 12 comparative systems, 12 real life scenario tasks and 50 subjects. The quantitative data analysis shows encouraging observations on ease of use and usefulness of the proposed framework, and also reveals a large variance of the results depending on different user types. Accordingly, based on Information Foraging Theory, we further propose a user classification model along three user interaction dimensions: information goals (I), search strategies (S) and evaluation thresholds (E) of users. To our best knowledge, this is the first principled user classification model in CBIR. The model is operated and verified by a systematic qualitative data analysis based on multi linear regression on the real user interaction data from comparative user evaluations. From final quantitative and qualitative data analysis based on the ISE model, we have established what different types of users like about the framework and their preferences for interactive CBIR systems. Our findings offer useful guidelines for interactive search system design, evaluation and analysis.

description: In the paper we described major trends of changes across 2002-2010 in one category of farming system called „declining agriculture with diversification” which was identified within 8 gminas of Podlaskie province using national agricultural census data conducted in 2002. It was found that the trends of these trajectories were rather similar to those showed generally across the entire areas of Poland including Podlaskie province. An unfavorable aspect of these changes on the area involves decreasing the number of economic enterprises related to 2002. Then, rural community settled in the area of these communes has to search additional incomes outside place of their residence. Therefore, local authorities should supportsubstantially non-agricultural activities located both on farms and off farms.

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The profile of the fluorescent iron line from black hole accretion disks is a powerful diagnostic of black hole properties, such as spin and inclination. The state-of-the-art, however, considers an accretion disk whose angular momentum is aligned with that of the black hole; this is a very constraining assumption which is unlikely to apply to many or even most astrophysical systems. Here, we present the first simulation of the reflection spectrum from warped accretion disks using a realistic model of the reflected emission based on the xillver code. We present the effects that the radial location of the warp and the tilt angle have on the line profile, and highlight that the results are highly dependent on the azimuth position of the observer relative to the tilt angle. We fit these profiles in XSpec with the standard relxill lamppost model to quantify the effect that neglecting the disk warps has on the inferred black hole spins and inclinations. We show that fits with two-component relxill can be used to derive more accurate spin and inclination estimates.

In particular, we prove that if $φ\colon \!M^2 \ra D \subseteq \R^3$ is a minimal immersion into an open, bounded, strictly convex subset $D$ with $C^2$-boundary, then $M$ has discrete spectrum provided that $\haus_Ψ(\limφ\cap D)=0$, where $\haus_Ψ$ is the generalized Hausdorff measure of order $Ψ(t) = t^2|\log t|$. Our theorem applies to a number of examples recently constructed by various authors in the light of N. Nadirashvili's discovery of complete, bounded minimal disks in $\R^3$, as well as to solutions of Plateau's problems, giving a fairly complete answer to a question posed by S.T. Yau in his Millenium Lectures. Suitable counter-examples show the sharpness of our results: in particular, we develop a simple criterion for the existence of essential spectrum which is suited for the techniques developed after Jorge-Xavier and Nadirashvili's examples.

description: We derive the UV-optical stellar dust attenuation curve of galaxies at z=1.4-2.6 as a function of gas-phase metallicity. We use a sample of 218 star-forming galaxies, excluding those with very young or heavily obscured star formation, from the MOSFIRE Deep Evolution Field (MOSDEF) survey with H$α$, H$β$, and [NII]$λ6585$ spectroscopic measurements. We constrain the shape of the attenuation curve by comparing the average flux densities of galaxies sorted into bins of dust obscuration using Balmer decrements, i.e., H$α$-to-H$β$ luminosities. The average attenuation curve for the high-metallicity sample (12+log(O/H)>8.5, corresponding to $M_*\gtrsim10^{10.4}\,M_{\odot}$) has a shallow slope, identical to that of the Calzetti local starburst curve, and a significant UV 2175A extinction bump that is $\sim 0.5\times$ the strength of the Milky Way bump. On the other hand, the average attenuation curve of the low-metallicity sample (12+log(O/H) $\sim 8.2-8.5$) has a steeper slope similar to that of the SMC curve, only consistent with the Calzetti slope at the $3σ$ level. The UV bump is not detected in the low-metallicity curve, indicating the relative lack of the small dust grains causing the bump at low metallicities. Furthermore, we find that on average the nebular reddening (E(B-V)) is a factor of 2 times larger than that of the stellar continuum for galaxies with low metallicities, while the nebular and stellar reddening are similar for galaxies with higher metallicities. The latter is likely due to a high surface density of dusty clouds embedding the star forming regions but also reddening the continuum in the high-metallicity galaxies.

Propagation and Signatures of Ultra High Energy Cosmic Rays

description: We study the extragalactic protons with universal spectrum, which is independent of mode of propagation, when distance between sources is less than the propagation lengths, such as energy attenuation length or diffusion length (for propagation in magnetic fields). The propagation features in this spectrum, the GZK cutoff, dip and bump, are studied with help of modification factor, which weakly depends on the generation spectrum index $γ_g$. We argue that from the above features the dip is the most model-independent one. For the power-law generation spectrum with $γ_g=2.7$ the dip is very well confirmed by the data of all existing detectors, which gives the strong evidence for extragalactic protons propagating through CMB. We develop the AGN model for origin of UHECR, which successfully explains the observed spectra up to $1\times 10^{20}$ eV and transition from galactic to extragalactic cosmic rays. The calculated spectrum has the GZK cutoff, and the AGASA excess of events at $E \gsim 1\times 10^{20}$ eV needs another component, e.g. from superheavy dark matter. In case of weak extragalactic magnetic fields this model is consistent with small-angle clustering and observed correlation with BL Lacs.

Supernova Neutrino Process and its Impact on the Galactic Chemical Evolution of the Light Elements

description: In order to resolve the overproduction problem of 11B in supernova explosions during Galactic chemical evolution, the dependence of the ejected masses of the light elements produced through the nu-process in supernova explosions on supernova neutrino parameters is investigated and constraints on the supernova neutrinos are evaluated. Detailed nucleosynthesis in a supernova explosion model corresponding to SN 1987A is calculated by postprocessing. The ejected masses of 11B and 7Li depend strongly on the temperature of mu- and tau-neutrinos and their antiparticles and are roughly proportional to the total neutrino energy. The range of temperature of mu- and -tau neutrinos and their antiparticles appropriate for the amount of 11B necessary for Galactic chemical evolution and the total neutrino energy deduced from the gravitational energy of a typical neutron star is between 4.8 MeV and 6.6 MeV. In the case of neutrino energy spectra with non-zero chemical potential, this range decreases by about 10%.

title: Boundaries, bricolage and student-teacher learning
Creators: name: Hutchinson, Steven Andrew
Publisher: name: The Open University
Year: 2008

description: This thesis explores the learning opportunities that are presented to student-teachers as they talk about teaching and learning with their school-based mentor and part-time university-based tutor. Against the backcloth of endemic complexity in initial teacher education, the study asks what these conversations tell us about student-teacher learning. What each of these participants talk about, the sources they draw on and the levels of agreement, disagreement or contradiction evident in their conversations with one another are issues that are central to developing an understanding of this research problem and to this thesis. The thesis adopts an activity theoretical approach, complemented by a social learning theory perspective, to investigate the way that boundaries between university study and the classroom as a site for work-based learning are seen as learning assets. The research is in two phases, the first in the form of a scoping questionnaire which attempts to identify the level of perceived contradiction by student-teachers on a PGCE course and the second in the form of four case studies. A variety of data-gathering tools and methods inform the studies and, in particular, content analysis is used to examine and report on conversations which centre around one taught lesson in each case. The study reveals understandings about the way that learning opportunities are presented to student-teachers. When teaching is presented as a process of bricolage and when provenance is not fully articulated, opportunities for expansive and systemic learning are restricted. The thesis argues that by looking at student-teacher learning systemically, with a focus on dissonance, student-teacher learning can be enhanced. It concludes with recommendations for the Open University PGCE programme team.

description: In this paper, we consider mappings on uniform domains with exponentially integrable distortion whose Jacobian determinants are integrable. We show that such mappings can be extended to the boundary and moreover these extensions are exponentially integrable with quantitative bounds.

description: The ground state of neutral and negatively charged excitons confined to a single self-assembled InGaAs quantum dot is probed in a direct absorption experiment by high resolution laser spectroscopy. We show how the anisotropic electron-hole exchange interaction depends on the exciton charge and demonstrate how the interaction can be switched on and off with a small dc voltage. Furthermore, we report polarization sensitive analysis of the excitonic interband transition in a single quantum dot as a function of charge with and without magnetic field.

description: The glow discharge's main ionization breakdown processes have been understood for about one hundred years. The glow discharge, however, still remains an area of active research in relation to pattern formation and far-from-equilibrium systems. The primary and secondary ionization processes can be mathematically modelled as general branching processes. Not only is the Townsend breakdown criterion obtained but the ionization avalanche can be characterized as a branching set with a unique Hausdorff fractal dimension. These fractal dimensions can be utilized in applications using similarity principles and Paschen's Law.
