title: Entwurf einer Phänomenologie des Anderen im digitalen Bild samt Influencertum als Fallstudie
Creators: name: Wild, Lena
Year: 2022

description: Gegenstand der vorliegenden Arbeit ist eine phänomenologische Betrachtung der Veränderung interpersonaler Alteritätsrelationen bei Übertragung der Interaktion in den digitalen Raum. Der verfolgte Ansatz deckt folglich die zwei Bereiche von Alterität und Medialität im Digitalen ab, wobei in diesem Zusammenhang von einer nichtnormativen, zweifachen Mediatisierung ausgegangen werden muss. Die erste solche Mediatisierung ist jene der Übertragung von Kommunikation in das Medium des digitalen Raumes, welche gegenüber dem real life neben einer ternären Alteritässtruktur – reales Selbst, virtueller Avatar, virtueller Anderer – sowie einer Trichotomie der Öffentlichkeit unter anderem auch den Imperativ zu explizit ausgedrückter Anwesenheit und Authentizität in der Intimität mit sich bringt. Die zweite Mediatisierung hingegen beschreibt eine zusätzliche Mediatisierung im Bild als Kommunikationskanal im bereits einmal mediatisierten Raum des Digitalen. Dieses Medium Bild im Medium Internet wirkt auf Relevanz, Resonanz, Performanz und Distanz der Kommunikation, indem es den Informationsaustausch in der Tiefe durch eine zweifache Zerrspiegelung des Bildes und eine zweifache Übersetzungstätigkeit der Kommunizierenden unter der scheinbar transparenten Oberfläche verrauscht. Der Verlust an Transparenz geht einher mit Freiheiten der Gestaltung und Rezeption bei Sender und Empfänger, worin – so die Hypothese – nicht zu unwesentlichen Teilen der breite Zuspruch zu einschlägigen social media Plattformen begründet liegt. Zur Validierung des Ansatzes aus zweifacher Mediatisierung bietet sich schließlich als Fallbeispiel das Influencertum an, welches sich als relevantes Phänomen für die Untersuchung der „Symptomatik“ von Influencer-Followerbeziehungen eignet. Den Anschauungsgrund bilden dabei neben ausgewählten Beispielen auch Erkenntnisse der Medienwissenschaft zu (virtual) Influencern.

description: In this paper, we present a novel approach to model the fluid/solid interaction forces in a direct solver of the Navier-Stokes equations based on the volume of fluid interface tracking method. The key ingredient of the model is the explicit inclusion of the fluid/solid interaction forces into the governing equations. We show that the interaction forces lead to a partial wetting condition and in particular to a natural definition of the equilibrium contact angle. We present two numerical methods to discretize the interaction forces that enter the model; these two approaches differ in complexity and convergence. To validate the computational framework, we consider the application of these models to simulate two-dimensional drops at equilibrium, as well as drop spreading. We demonstrate that the model, by including the underlying physics, captures contact line dynamics for arbitrary contact angles. More generally, the approach permits novel means to study contact lines, as well as a diverse range of phenomena that previously could not be addressed in direct simulations.

description: Die vorherrschende Vielfachkrise äußert sich unter anderem in einer Krise der Ernährung. In der vorliegenden Masterarbeit wird untersucht, ob es eine sozial-ökologische Transformation der Gemeinsamen Agrarpolitik der Europäischen Union braucht und wie diese ausgestaltet werden müsste. Die Gründe für eine Transformation werden mithilfe von Konzepten kritischpolitökonomischer Theoriestränge, genauer der Imperialismus-, Neokolonialismus-, Regulations- und Dependenztheorien, dem Neogramscianismus sowie der Wissenschaftstheorie des Kritischen Realismus untermauert. Diese Theorien bieten ebenso Anhaltspunkte dafür, warum es nicht zu einer solchen Transformation kommt und welche Akteur:innen sich für einen Erhalt des Status quo aussprechen. Diese Gründe werden durch eine Betrachtung von Begriffen des agrarpolitischen Diskurses anhand des Framing-Ansatzes ergänzt. Für eine Darstellung sozial gerechter und ökologisch nachhaltiger Produktionsformen, die als Alternativen zur aktuellen agrarkapitalistischen Produktionsweise in der EU betrachtet werden können, werden die Perspektiven gegenhegemonialer Organisationen und Bewegungen herangezogen. Damit soll festgestellt werden, ob und inwiefern eine sozial-ökologische Transformation der europäischen Agrarpolitik möglich ist.

description: We use the "Evolution and assembly of galaxies and their environments" (EAGLE) cosmological simulation to investigate the effect of baryons on the density profiles of rich galaxy clusters. We focus on EAGLE clusters with $M_{200}>10^{14}~M_\odot$ of which we have six examples. The central brightest cluster galaxies (BCGs) in the simulation have steep stellar density profiles, $ρ_*(r) \propto r^{-3}$. Stars dominate the mass density for $r<10~\rm{kpc}$, and, as a result, the total mass density profiles are steeper than the Navarro-Frenk-White (NFW) profile, in remarkable agreement with observations. The dark matter halo itself closely follows the NFW form at all resolved radii ($r\gtrsim3.0~\rm{kpc}$). The EAGLE BCGs have similar surface brightness and line-of-sight velocity dispersion profiles as the BCGs in the sample of Newman et al., which have the most detailed measurements currently available. After subtracting the contribution of the stars to the central density, Newman et al. infer significantly shallower slopes than the NFW value, in contradiction with the EAGLE results. We discuss possible reasons for this discrepancy, and conclude that an inconsistency between the kinematical model adopted by Newman et al. for their BCGs, which assumes isotropic stellar orbits, and the kinematical structure of the EAGLE BCGs, in which the orbital stellar anisotropy varies with radius and tends to be radially biased, could explain at least part of the discrepancy.

description: Zielsetzung. Geschlechtergerechte Sprache erreicht nachweislich das Ziel, mehr Menschen in ihrer Vielfalt, jenseits der Geschlechterbinarität, zu repräsentieren, als es generischer Sprache möglich ist. Auf dem Weg, einen maßgeblichen Beitrag zur Gleichstellung der Geschlechter zu leisten, stößt geschlechtergerechter Sprachgebrauch nicht selten auf Unverständnis und Reaktanz. Die Frage nach dem Einfluss unserer Veränderungsakzeptanz auf den Gebrauch geschlechtergerechter Sprache wurde dabei noch nie gestellt, weshalb die vorliegende Masterarbeit das Ziel verfolgt, den Zusammenhang zwischen dem Ausmaß der ‚Akzeptanz von Veränderungen‘ und dem Effekt von Input mittels geschlechtergerecht formulierter Sprache auf den Ge-brauch derselben, darzulegen. Methode. Um eine zufriedenstellende Beantwortung dieser Fragestellung gewährleisten zu können, wurde ein experimentelles Forschungsdesign, in Anlehnung an die Studie von Koeser et al.

Der geschlechtergerechte Sprachgebrauch konnte dabei anhand von zehn Lückentextaufgaben operationalisiert werden (Kuhn / Gabriel 2014), wobei die Datenerhebung mit 190 randomisierten Versuchsteilnehmer*innen online erfolgte. Um die Qualität der Manipulation sowie die Kohärenz der übersetzten Acceptance of Change Scale (di Fabio / Gori 2016) zu überprüfen, wurden zwei Pretests durchgeführt. Ergebnisse. Die Untersuchung zeigte, dass sowohl Frauen als auch Männer nach der Lektüre von geschlechtergerecht formulierten Texten nicht mehr geschlechtergerechte Formen verwendeten als nach Lektüre der nicht geschlechtergerecht formulierten Texte. Trotz der Tatsache, dass in der vorliegenden Untersuchung die Ergebnisse der Vorläuferstudie von Koeser et al. (2014) nur zum Teil repliziert werden konnten, zeigt sich, dass die Nutzung geschlechtergerechter Sprache nicht in einem Abhängigkeitsverhältnis zur Veränderungsakzeptanz steht. Dem Bildungsstand beziehungsweise schulischen, universitären und berufspolitischen Richtlinien werden zudem eine zentrale Bedeutung zugeschrieben. Beitrag. Aus theoretischer Sicht erweitert die vorliegende Arbeit den Forschungsstand in Bezug auf Prädiktoren und Barrieren hinsichtlich geschlechtergerechter Sprache. Darüber hinaus macht diese Studie den Effekt der Uneinheitlichkeit geschlechtergerechter Sprache sichtbar, der in einer intra- sowie interindividuellen inkonsistenten Verwendung entsprechender Sprachformen zu resultieren scheint.
Design Principles for More-than-Data Walks
Creators: name: Mullagh, Louise
Publisher: name: Lancaster University
Year: 2022

description: With the rise of the data-driven society, there is a danger of losing insights of unique, nuanced, and complex dynamics that are critical to our understanding of and engagement with place. This research establishes how the use of walking reveals the concept of More-than-Data. This concept forms the basis of a series of design principles capable of engaging with complex, unique, and temporal placed-based data, information, knowledge, wisdom and lived experience. Our understanding and experience of the places we inhabit are being increasingly mediated by technologies, many of which are driven by quantitative, automatically gathered data. These types of data can provide us with huge amounts of information once processed and analysed, however this data-driven mediation of our spaces and places is but one way of understanding and experiencing the world in which we live. Whilst these types of automatically gathered data enable us to gain valuable insights into our world, the reliance upon outsourcing our senses and collecting data are often illegible to many people who do not possess the skills or equipment to engage in these modes of quantifying and mapping place. Other, valuable types of data exist in place, but these are often latent within place or people and more difficult to access. Therefore, those who have much to contribute to increasing knowledge about our world, are often excluded. This research explores the knowledge gap that exists in understanding how these data-driven and situated modes of understanding place might be synthesised and contributes to a growing body of research that explores how we might interrogate the data-driven society through the practice of walking. This nascent approach answers calls for critical approaches to understanding the impact of the data-driven society by moving through a place and exploring what data means in that location. Through the exploration of practices that are located within the data-driven realm the concept of More-than-Data emerged and is defined as “a heuristic guide that encourages and embeds the collection, conceptualisation, interrogation, storage and re-use of data, information, knowledge, wisdom and lived-experience in, from and through place.” To explore how More-than-Data can be embedded within a practice, five walks were designed and carried out. The insights developed through the walks have been synthesised with findings from literature and interviews carried out, to form the basis for a set of design heuristics. The three key contributions to knowledge presented in this research are: 1. The concept of More-than-Data 2. A set of design principles that can be used by a wide range of people that embed More-than-Data in place. 3. The “Pathways Forward” Method that can be used to collate and make sense of emergent findings that brings together diverse types of research data and artefacts.

description: In the present work we search for a new wormhole solution inspired by noncommutative geometry with the additional condition of allowing conformal Killing vectors (CKV). A special aspect of noncommutative geometry is that it replaces point-like structures of gravitational sources with smeared objects under Gaussian distribution. However, the purpose of this paper is to obtain wormhole solutions with noncommutative geometry as a background where we consider a point-like structure of gravitational object without smearing effect. It is found through this investigation that wormhole solutions exist in this Lorentzian distribution with viable physical properties.

This deliverable summarises the work of WP6 to deliver a FAIRsharing Collection of these data resources (and associated standards) to ensure these resources are Findable (e.g. discoverable and citable via a DOI), Accessible (e.g. access methods to their data is clearly described), Interoperable (e.g. standards implemented are declared) and Re-usable (e.g. terms of use of the data are made explicit to users). This work is described in detail in D1.2 and D1.3, and the EOSC-Life FAIRsharing Collection of 133 records (as of Aug 2022) is publicly available. As this is a live view of the EOSCLife resource ecosystem, a variety of stages of the resource life cycle are displayed. Indevelopment, Ready and Deprecated resources are marked as such allowing users to assess their relevance. In Jan 2022 a newly improved FAIRsharing backend and frontend was also released by the UOXF partner, who also runs and curates the registry. This new version is set to improve the discoverability of and the relationships among the resources, and also offers new RI-centric pages (e.g. ELIXIR and MIRRI). These pages enable attribution at the level of the RIs and the responsible individuals themselves. Each RI page in FAIRsharing showcases its associated repositories, standards and collections and identifies and attributes (via ORCID) related users. The records in the EOSC-Life FAIRsharing Collection are a part of the wider FAIRsharing registry, which is computationally accessible to a wide variety of third-party tools, and which is interoperable with pan-EOSC activities via the FAIRsharing collaboration with OpenAIRE.
title: Die Qualität der maschinellen Übersetzung im Rechtsbereich anhand einer Fehlertypologie am Beispiel Russisch-Deutsch
Creators: name: Dunina, Kristina

description: Die vorliegende Arbeit setzt sich mit der Qualität der maschinellen Übersetzung mit dem Schwerpunkt Rechtsübersetzung auseinander. In der Arbeit wird analysiert, welche Arten von Fehlern maschinell übersetze Texte am häufigsten aufweisen. Es wird überprüft, ob falsche Terminologie die Fehlerkategorie ist, in der die meisten Fehler zu finden sind. Für die Untersuchung werden vier Texte aus dem Rechtsbereich aus dem Russischen ins Deutsche maschinell übersetzt. Für die Erstellung maschineller Übersetzungen wird der neuronale maschinelle Online-Übersetzter DeepL verwendet. Die maschinellen Übersetzungen werden anhand der Fehlertypologie der SAE-J2450 manuell evaluiert. Die Untersuchung der maschinell erstellten Übersetzungen zeigt, dass das untersuchte NMÜ-System im Bereich der Rechtsübersetzung eine ungenügende Übersetzungsqualität liefert, da keiner der maschinell übersetzten Texte die SAE-J2450-Qualitätsprüfung bestanden hat. Fast die Hälfte aller festgestellten Fehler (48 %) gehört zur Kategorie „falsche Benennung“, die sich mit der Verwendung der falschen Terminologie befasst. Dies deutet darauf hin, dass das Problem der richtigen Terminologie dem NMÜ-System DeepL große Schwierigkeiten bereitet. Die Untersuchungsergebnisse lassen annehmen, dass die meisten Schwierigkeiten des DeepL-Systems mit der mangelnden Zuverlässigkeit des verwendeten Korpus zusammenhängen.
Relation between Random Walks and Quantum Walks

description: Based on studies on four specific networks, we conjecture a general relation between the walk dimensions $d_{w}$ of discrete-time random walks and quantum walks with the (self-inverse) Grover coin. In each case, we find that $d_{w}$ of the quantum walk takes on exactly half the value found for the classical random walk on the same geometry. Since walks on homogeneous lattices satisfy this relation trivially, our results for heterogeneous networks suggests that such a relation holds irrespective of whether translational invariance is maintained or not. To develop our results, we extend the renormalization group analysis (RG) of the stochastic master equation to one with a unitary propagator. As in the classical case, the solution $ρ(x,t)$ in space and time of this quantum walk equation exhibits a scaling collapse for a variable $x^{d_{w}}/t$ in the weak limit, which defines $d_{w}$ and illuminates fundamental aspects of the walk dynamics, e.g., its mean-square displacement. We confirm the collapse for $ρ(x,t)$ in each case with extensive numerical simulation. The exact values for $d_{w}$ in themselves demonstrate that RG is a powerful complementary approach to study the asymptotics of quantum walks that weak-limit theorems have not been able to access, such as for systems lacking translational symmetries beyond simple trees.

On the Factorization of Rational Discrete-Time Spectral Densities

description: In this paper, we consider an arbitrary matrix-valued, rational spectral density $Φ(z)$. We show with a constructive proof that $Φ(z)$ admits a factorization of the form $Φ(z)=W^\top (z^{-1})W(z)$, where $W(z)$ is stochastically minimal. Moreover, $W(z)$ and its right inverse are analytic in regions that may be selected with the only constraint that they satisfy some symplectic-type conditions. By suitably selecting the analyticity regions, this extremely general result particularizes into a corollary that may be viewed as the discrete-time counterpart of the matrix factorization method devised by Youla in his celebrated work (Youla, 1961).

Is the Kinetoplast DNA a Percolating Network of Linked Rings at its Critical Point?

description: In this work we present a computational study of the Kinetoplast genome, modelled as a large number of semiflexible unknotted loops, which are allowed to link with each other. As the DNA density increases, the systems shows a percolation transition between a gas of unlinked rings and a network of linked loops which spans the whole system. Close to the percolation transition, we find that the mean valency of the network, i.e. the average number of loops which are linked to any one loop, is around 3 as found experimentally for the Kinetoplast DNA. Even more importantly, by simulating the digestion of the network by a restriction enzyme, we show that the distribution of oligomers, i.e. structures formed by a few loops which remain linked after digestion, quantitatively matches experimental data obtained from gel electrophoresis, provided that the density is, once again, close to the percolation transition. With respect to previous work, our analysis builds on a reduced number of assumptions, yet can still fully explain the experimental data. Our findings suggest that the Kinetoplast DNA can be viewed as a network of linked loops positioned very close to the percolation transition, and we discuss the possible biological implications of this remarkable fact.

Derivation of quantum probabilities from deterministic evolution
Creators: name: Philbin, T. G.
Publisher: name: arXiv
Year: 2014
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The predictions of quantum mechanics are probabilistic. Quantum probabilities are extracted using a postulate of the theory called the Born rule, the status of which is central to the "measurement problem" of quantum mechanics. Efforts to justify the Born rule from other physical principles, and thus elucidate the measurement process, have involved lengthy statistical or information-theoretic arguments. Here we show that Bohm's deterministic formulation of quantum mechanics allows the Born rule for measurements on a single system to be derived, without any statistical assumptions. We solve a simple example where the creation of an ensemble of identical quantum states, together with position measurements on those states, are described by Bohm's quantum dynamics. The calculated measurement outcomes agree with the Born-rule probabilities, which are thus a consequence of deterministic evolution. Our results demonstrate that quantum probabilities can emerge from simple dynamical laws alone, and they support the view that there is no underlying indeterminism in quantum phenomena.

title: Maternal Occupation and Pediatric Brain Cancer in Kentucky

Subjects: classificationCode: 3.3
subject: FOS: Health sciences

description: Pediatric brain cancer is a rare and potentially deadly diagnosis that affects children in Kentucky at a higher incidence than those nationally. Limited exposures in children early in life to warrant the development and progression of brain cancer point to the role parental exposures experienced in the period prior to conception and throughout pregnancy may play in its development. Many of these exposures may be experienced through occupation.

Data on a subset of pediatric brain cancer cases in Kentucky was compared to all cases diagnosed in the state from 1995 to 2019. Survey data of the study sample was collected and work-related characteristics of biological mothers of the sample were standardized using industry codes and analyzed to identify occupation fields with potential associations to pediatric brain cancer. Cases diagnosed at a younger age and those from metropolitan areas were over-represented in the sample. The maternal occupation of the sample varied slightly from the occupational prevalence of the general population. However, since the comparison was made to all working women in the United States 16 years and older, the comparison is flawed. Additional research is needed to verify these findings and identify additional exposures that may contribute to cancer development.

Understanding rigid body motion in arbitrary dimensions

subject: FOS: Physical sciences

description: Why would anyone wish to generalize the already unappetizing subject of rigid body motion to an arbitrary number of dimensions? At first sight, the subject seems to be both repellent and superfluous. The author will try to argue that an approach involving no specifically three-dimensional constructs is actually easier to grasp than the traditional one and might thus be generally useful to understand rigid body motion both in three dimensions and in the general case. Specific differences between the viewpoint suggested here and the usual one include the following: here angular velocities are systematically treated as antisymmetric matrices, a symmetric tensor $I$ quite different from the moment of inertia tensor plays a central role, whereas the latter is shown to be a far more complex object, namely a tensor of rank four. A straightforward way to define it is given. The Euler equation is derived and the use of Noether's theorem to obtain conserved quantities is illustrated. Finally the equation of motion for two bodies linked by a spherical joint is derived to display the simplicity and the power of the method.

description: Novel mechanisms of defect annealing in solids are discussed, which are based on the large amplitude anharmonic lattice vibrations, a.k.a. intrinsic localized modes or discrete breathers (DBs). A model for amplification of defect annealing rate in Ge by low energy plasma-generated DBs is proposed, in which, based on recent atomistic modelling, it is assumed that DBs can excite atoms around defects rather strongly, giving them energy $\gg k_BT$ for $\sim$100 oscillation periods. This is shown to result in the amplification of the annealing rates proportional to the DB flux, i.e. to the flux of ions (or energetic atoms) impinging at the Ge surface from inductively coupled plasma (ICP)

We null the diffraction phase and increase the sensitivity of the interferometer by combining Bragg diffraction with Bloch oscillations. We demonstrate agreement between experiment and theory, and a 1500-fold reduction of the diffraction phase, limited by measurement noise. In addition to reduced systematic effects, our interferometer has high contrast with up to 4.4 million radians of phase difference, and a resolution in the fine structure constant of $δα/α=0.25\,$ppb in 25 hours of integration time.

description: A Fubini instanton is a bounce solution which describes the decay of a vacuum state located at the top of the tachyonic potential {\it via} the tunneling without a barrier. We investigate various types of Fubini instantons of a self-gravitating scalar field under a tachyonic quartic potential. With gravity taken into account, we show there exist various types of unexpected solutions including oscillating bounce solutions. We present numerically oscillating Fubini bounce solutions in anti-de Sitter and de Sitter spaces. We construct the parametric phase diagrams of the solutions, which is the extension of our previous work. Of particular significance is that there always exist solutions in all parameter spaces in anti-de Sitter space. The regions are divided depending on the number of oscillations. On the other hand, de Sitter space allows solutions with codimension-one in parameter spaces. We numerically evaluate semiclassical exponents which give the finite tunneling probabilities.

Furthermore, we unfold the emergence of a peculiar Dirac-shaped dispersion for specific strain conditions, including the zigzag-oriented tensile strain. The observed linear energy spectrum has distinct velocities corresponding to each of its linear branches and is limited to the $Γ-X$ direction in the first Brillouin zone.

title: Experimental evidence: loss of control & immigration attitudes
Creators: name: Polzin, Julian
Year: 2022

description: Diese Master-Thesis führt ein Experiment ein, das den Einfluss eines empfundenen Kontrollverlustes auf die Einstellung zu Immigration untersucht. In einer Sequenz von Entscheidungen, die einen Immigrationskontext suggerieren, sind die Subjekte der Einmischung eines Computers ausgesetzt. Es besteht die Möglichkeit Kosten in einen Protest zu investieren, um sich gegen diese Störung zu wehren. Die Resultate zeigen, dass die Subjekte bereit sind einen Kontrollaufschlag zu bezahlen, um die Kontrolle über ihre Entscheidungen wiederzuerlangen, was im Einklang mit der einschlägigen Literatur steht. Darüber hinaus scheinen Immigrationsentscheidungen von einer Verbindung aus Risiko- und sozialen Präferenzen wie auch Übertragungseffekten des Gefühls von Kontrollverlust abzuhängen. Daher deutet das neuartige experimentelle Design darauf hin, dass Kontrollpräferenzen eine Rolle in der Bildung von Einstellungen zu Immigration spielen.
description: This master thesis introduces an experiment which explores the impact of perceived control loss on immigration attitudes. In a sequence of choices that are framed as immigration decisions, subjects face interference from the computer which can be resisted by performing a costly protest. The results show that subjects are willing to pay a control premium to gain back control over their decisions which is in line with observations from the literature. Moreover, immigration decisions seem to be influenced by a compound of social and risk preferences as well as spillover effects from the feeling of control loss. Hence, the novel experimental design indicates that control preferences play a role in the forming of immigration attitudes.
Composition Operators on Bohr-Bergman Spaces of Dirichlet Series

description: For $α\in \mathbb{R}$, let $\mathscr{D}_α$ denote the scale of Hilbert spaces consisting of Dirichlet series $f(s) = \sum_{n=1}^\infty a_n n^{-s}$ that satisfy $\sum_{n=1}^\infty |a_n|^2/[d(n)]^α< \infty$. The Gordon--Hedenmalm Theorem on composition operators for $\mathscr{H}^2=\mathscr{D}_0$ is extended to the Bergman case $α>0$. These composition operators are generated by functions of the form $Φ(s) = c_0 s + φ(s)$, where $c_0$ is a nonnegative integer and $φ(s)$ is a Dirichlet series with certain convergence and mapping properties. For the operators with $c_0=0$ a new phenomenon is discovered: If $0 < α< 1$, the space $\mathscr{D}_α$ is mapped by the composition operator into a smaller space in the same scale. When $α> 1$, the space $\mathscr{D}_α$ is mapped into a larger space in the same scale. Moreover, a partial description of the composition operators on the Dirichlet--Bergman spaces $\mathscr{A}^p$ for $1 \leq p < \infty$ are obtained, in addition to new partial results for composition operators on the Dirichlet--Hardy spaces $\mathscr{H}^p$ when $p$ is an odd integer.

Comparison and verification of enthalpy schemes for polythermal glaciers and ice sheets with a one-dimensional model

description: The enthalpy method for the thermodynamics of polythermal glaciers and ice sheets is tested and verified by a one-dimensional problem (parallel-sided slab). The enthalpy method alone does not include explicitly the transition conditions at the cold-temperate transition surface (CTS) that separates the upper cold from the lower temperate layer. However, these conditions are important for correctly determining the position of the CTS. For the numerical solution of the polythermal slab problem, we consider a two-layer front-tracking scheme as well as three different one-layer schemes (conventional one-layer scheme, one-layer melting CTS scheme, one-layer freezing CTS scheme). Computed steady-state temperature and water-content profiles are verified with exact solutions, and transient solutions computed by the one-layer schemes are compared with those of the two-layer scheme, considered to be a reliable reference. While the conventional one-layer scheme (that does not include the transition conditions at the CTS) can produce correct solutions for melting conditions at the CTS, it is more reliable to enforce the transition conditions explicitly. For freezing conditions, it is imperative to enforce them because the conventional one-layer scheme cannot handle the associated discontinuities. The suggested numerical schemes are suitable for implementation in three-dimensional glacier and ice-sheet models.

Diffusion in the Mean for an Ergodic Schrödinger Equation Perturbed by a Fluctuating Potential

description: Diffusive scaling of position moments and a central limit theorem are obtained for the mean position of a quantum particle hopping on a cubic lattice and subject to a random potential consisting of a large static part and a small part that fluctuates stochastically in time. If the static random potential is strong enough to induce complete localization in the absence of time dependent noise, then the diffusion constant is shown to go to zero proportional to the square of the strength of the time dependent part.

description: Quantum Private Comparison (QPC) allows us to protect private information during its comparison. In the past various three-party quantum protocols have been proposed that claim to work well under noisy conditions. Here we tackle the problem of QPC under noise. We analyze the EPR-based protocol under depolarizing noise, bit flip and phase flip noise. We show how noise affects the robustness of the EPR-based protocol. We then present a straightforward protocol based on CSS codes to perform QPC which is robust against noise and secure under general attacks.

Time-reversal Invariant SU(2) Hofstadter Problem in Three Dimensional Lattices

description: We formulate the lattice version of the three-dimensional SU(2) Landau level problem with time reversal invariance. By taking a Landau-type gauge, the system is reduced into the one-dimensional SU(2) Harper equation characterized by a periodic spin-dependent gauge potential. The surface spectra indicate the spatial separation of helical states with opposite eigenvalues of the lattice helicty operator. The band topology is investigated from both the analysis of the boundary helical Fermi surfaces and the calculation of the Z2-index based on the bulk wavefunctions. The transition between a 3D weak topological insulator to a strong one is studied as varying the anisotropy of hopping parameters.

description: The classical problem of construction of Gardner's deformations for infinite-dimensional completely integrable systems of evolutionary partial differential equations (PDE) amounts essentially to finding the recurrence relations between the integrals of motion. Using the correspondence between the zero-curvature representations and Gardner deformations for PDE, we construct a Gardner's deformation for the Krasil'shchik-Kersten system. For this, we introduce the new nonlocal variables in such a way that the rules to differentiate them are consistent by virtue of the equations at hand and second, the full system of Krasil'shchik-Kersten's equations and the new rules contains the Korteweg-de Vries equation and classical Gardner's deformation for it.

description: Let A and B be normal matrices with coefficients that are continuous complex-valued functions on a topological space X that has the homotopy type of a CW complex, and suppose these matrices have the same distinct eigenvalues at each point of X. We use obstruction theory to establish a necessary and sufficient condition for A and B to be unitarily equivalent. We also determine bounds on the number of possible unitary equivalence classes in terms of cohomological invariants of X.
