description: The prospects for direct measurements of inflationary gravitational waves by next generation interferometric detectors inferred from the possible detection of B-mode polarization of the cosmic microwave background are studied. We compute the spectra of the gravitational wave background and the signal-to-noise ratios by two interferometric detectors (DECIGO and BBO) for large-field inflationary models in which the tensor-to-scalar ratio is greater than the order of 0.01. If the reheating temperature $T_{\rm RH}$ of chaotic inflation with the quadratic potential is high ($T_{\rm RH}>7.9\times10^6$ GeV for upgraded DECIGO and $T_{\rm RH}> 1.8\times 10^{6}$ GeV for BBO), it will be possible to reach the sensitivity of the gravitational background in future experiments at $3σ$ confidence level. The direct detection is also possible for natural inflation with the potential $V(ϕ)=Λ^4 [1-\cos(ϕ/f)]$, provided that $f>4.2 M_{\rm pl}$ (upgraded DECIGO) and $f>3.6 M_{\rm pl}$ (BBO) with $T_{\rm RH}$ higher than $10^8$ GeV. The quartic potential $V(ϕ)=λϕ^4/4$ with a non-minimal coupling $ξ$ between the inflaton field $ϕ$ and the Ricci scalar $R$ gives rise to a detectable level of gravitational waves for $|ξ|$ smaller than the order of 0.01, irrespective of the reheating temperature.

title: When open-meets-digital: GOV.uk info-attention marketplace, actionable UK government priorities and agenda-attention

description: Social scientists have tried to decode institutional and societal priorities for decades – which issues/events/countries attract attention and how long they maintain their actionable agenda status. One of the reoccurring challenges in the process was the lack of accessible, standardised, and comparable data, especially when trying to identify government priorities and measure policy/public agenda-attention. However, as the adoption of web-based technology changes how government communicates and engages citizens, our ability to access open-digital information and make more accurate agenda observations has improved. As the role of centralised government portals expands, so is the need to examine how this ‘Open-Information meets Digital Attention’ nexus can help us identify actionable government priorities, improve our understanding of how issues are (re)prioritised and how those agenda-attention dynamics change over time. We consider the launch of GOV.uk in 2012 to be highly relevant for this research. Thanks to the portal’s centralised knowledge management system, standardised organisational typology, and uninformed search filters, we can now access new data, observe users’ preferences, and repurpose government information to establish associations between 357 departments/agencies, 47 policy areas, 219 policies, 49 topical events and 237 locations. The premise of this thesis is to examine the untapped potential of centralised government portals for agenda-attention research. We want to know if portals like GOV.uk can unlock alternative agenda-perspectives and data sources that can be aligned with existing theoretical frameworks as we seek to bridge a gap between theory and practice? We address this issue by contextualising GOV.uk as an ‘InfoAttention Marketplace’ – to be observed as a space where a Supply of digitised government information meets a digital footprint of users’ Demand for open data. In the process, we have used published government ‘info-flows’ to establish institutional preferences and the ‘pageview’ analytics to define public attentiveness for actionable government priorities over six years (10.05.2010 – 10.05.2016). Finally, we were able to demonstrate the applicability and resourcefulness of a centralised government portal for the agenda-attention research by (1) mapping out the UK Policy Platform and identifying the actionable government priorities; (2) computing policy/public agenda-attention frequency; (3) observing Aggregated-Coordinative-Communicative agenda-attention perspectives; (4) establishing a ranking order of institutional preferences along the Agenda-Attention Continuum; and (5) detecting the level of (miss)alignment between policy and public agendas when ‘Supply-meets-Demand’ on the GOV.uk platform.

description: Large-scale, scientist-led, participatory science (citizen science) projects often engage primarily participants who are White, wealthy, and well-educated. Calls to diversify contributory projects are increasingly common, but little research has evaluated the efficacy of suggested strategies for diversification. We engaged participants in Crowd the Tap through facilitator organizations like Historically Black Colleges and Universities (HBCUs), predominantly White institutions (PWI), high school science classrooms, and corporate volunteer programs. Crowd the Tap is a contributory project focused on identifying and addressing lead contamination in household drinking water in the United States. We investigated how participant diversity with respect to race, ethnicity, and homeownership (a proxy for income) differed between participation facilitated through a partner organization and in unfacilitated participation in which participants came to the project independently. We were also interested in which facilitators were most effective at increasing participant diversity. White and wealthy participants were overrepresented in unfacilitated participation. Facilitation helped increase engagement of people of color, especially Black households, and lower-income households. High schools were particularly effective at engaging Hispanic or Latino participants and HBCUs were important for engaging Black households. Ultimately, our results suggest that engagement through facilitator organizations may be an effective means of engaging diverse participants in large-scale projects. Our results have important implications for the field of participatory science as we seek to identify evidence-based strategies for diversifying project participants.

description: The data was collected through an IRB approved survey in which Crowd the Tap participants submitted data on the types of pipes they had, the age of their home, water aesthetics, and demographic information. As part of this process, participants also indicated if they came to the project through a partner organization (what we call facilitator organizations). We used information on reported types of facilitators, race and ethnicity, and homeownership (as a proxy for income) to investigate how diversity differed across facilitation.

description: This deliverable describes the ICS-C final architecture. Based on user satisfaction with the architectural design and simple prototype of EPOS-PP (Preparatory Phase) the initial architecture was defined. During the period M1-M18 of EPOS-IP (Implementation Phase) the architecture was refined based on interactions with the TCS and presented at EPOS project meetings. During the period M19-M36 progressive iterative prototypes driven by evolving user requirements and aspirations have been developed allowing the architecture to be specified in much more detail and the components refined and implemented. For some components (ICS-D, CES) implementation is continuing because this requires especially close working with the TCS. Detailed work has been undertaken validating the ICS-C against the evolving and increasingly ambitious user requirements and – in particular – collecting the metadata describing the assets in the TCS to populate the catalog. The architecture has been designed using the latest advances in metadata (for the catalog) and architectural approach (microservices). A consistent spiral, agile systems development method has been used. As part of this work the teams of WP6 and WP7 of EPOS – each spread across several organisations – have been integrated into a functioning unit with appropriate skills and abilities for the tasks. There has been some delay in recruitment to provide the human resources required but this has been overcome and the work is on schedule.

description: Fueled by the ever-increasing need for statistics that guarantee the privacy of their training sets, this article studies the centrally-private estimation of Sobolev-smooth densities of probability over the hypercube in dimension d. The contributions of this article are two-fold : Firstly, it generalizes the one dimensional results of (Lalanne et al., 2023) to non-integer levels of smoothness and to a high-dimensional setting, which is important for two reasons : it is more suited for modern learning tasks, and it allows understanding the relations between privacy, dimensionality and smoothness, which is a central question with differential privacy. Secondly, this article presents a private strategy of estimation that is data-driven (usually referred to as adaptive in Statistics) in order to privately choose an estimator that achieves a good bias-variance trade-off among a finite family of private projection estimators without prior knowledge of the ground-truth smoothness $β$. This is achieved by adapting the Lepskii method for private selection, by adding a new penalization term that makes the estimation privacy-aware.

description: ICS-D is the distributed component of ICS. ICS-D characteristics are documented in the metadata catalog and ICS-C utilises the user request and the catalog to generate a workflow to be deployed and executed across ICS-D using computing resources in the TCS environment and the e-I (e- Infrastructure) environment external to EPOS. ICS-D may be a distributed computing or sensor platform (whether in the field or in a laboratory) and also may be specialised software services integrated with a distributed computing platform e.g. for analytics, simulation or visualisation. We specify the updated elements of the characteristic description of ICS-Ds to be included in the catalog and the plan for the integration.

description: Die pandemiebedingte Schließung der Schulen und Universitäten setzte die Dringlichkeit von Digitalstrategien in der Fortbildungskultur von (Hoch)Schulen und die Notwendigkeit einer Stärkung medienpädagogischer Kompetenzen von Lehrenden, Studierenden sowie von Schülerinnen und Schülern vermehrt auf die bildungspolitische und gesellschaftliche Agenda. Eine Umstellung auf digital geprägte Lehr- und Lernangebote für den sogenannten Distanzunterricht musste jedoch unter großem Zeit- und Entscheidungsdruck erfolgen. Eine tiefergehende Auseinandersetzung mit der Medialität dieser veränderten Lehr- und Lernarrangements trat hinter pragmatischen Entscheidungen zurück. Damit einhergehend war vielerorts eine Vernachlässigung der ästhetisch-künstlerischen und damit körperlich, sinnlich erfahrbaren Ebene des Lehrens und Lernens zu beobachten (Krauß 2021 sowie der Beitrag von Anke Redecker in dieser Ausgabe). Die Suche nach den ästhetischen Wahrnehmungsdimensionen digitaler Lehr- und Lernmedien machte die Arbeitsgemeinschaft Medienkultur und -bildung der Gesellschaft für Medienwissenschaft daher zum Ausgangspunkt ihres Symposiums (2021), woraus auch die Schwerpunktbeiträge dieser Ausgabe stammen. Es sollten Lehr- und Lernformen in den Blick genommen werden, die durch digitale Medien wie beispielsweise Games, E-Portfolios, Videos, Webplattformen, Augmented-Reality- und Virtual-Reality-Anwendungen oder Apps unterstützt, erweitert, verändert oder womöglich ersetzt werden. Die Beiträge konnten unter anderem die folgenden Fragestellungen adressieren: • Wie können körperliche Ausdrucksformen und ästhetische Erfahrungen in digitale Formate überführt werden? • Welche Potenziale oder Herausforderungen lassen sich beim unterrichtlichen Einsatz von digitalen Medien im Hinblick auf ästhetische Praxis (Elberfeld/Krankenhagen 2017) ausmachen? Inwiefern sind dabei Fachperspektiven und unterrichtsspezifische Rollenzuschreibungen zu berücksichtigen? • Welche Formen der Bewertung von Leistung, Kompetenz und/oder Wissen werden durch digitale Medien etabliert oder in digitale Bildungsangebote eingeschrieben (Claussen 2021) und inwiefern werden dabei inklusive Prozesse oder künstlerische Artikulationen mitgedacht? • Werden im Rahmen der medialen Spezifikationen und Interfacegestaltungen von digitalen Bildungsangeboten bestimmte Körper idealisiert? Inwiefern findet eine Reflexion darüber statt, auf welche Körper und Medienpraktiken die Applikationen rekurrieren und welche diese hervorbringen (Orland 2005; Beinsteiner/Kohn 2016; Rode/Stern 2019)? • Wie kann über ästhetisch-künstlerische, partizipative Umgangsformen ein medienkritischer Zugang zu digitalen Medien im Unterricht geübt werden (Niesyto 2012/2013; Wiesche/Lipinski 2020)?

SUPERSPACE COMPUTATIONS IN SUSY AND SUGRA THEORIES
Creators: name: BANAUDI, ALESSANDRO
Publisher: name: Universit� degli Studi di Milano
Year: 2019

description: In this thesis, we present two current topics in theoretical high energy physics: We construct the Lagrangian of a deformed supergravity theory on a manifold with a non-trivial spacetime boundary by using the geometric (or rheonomic) approach and we discuss and analyze the supersymmetry invariance of the theory. Separately, we compute some scattering amplitudes in a supersymmetric conformal field theory with the Superspace formalism and Feynman superdiagrams. These two different topics conceptually achieve a contact point through the so-called AdS/CFT duality, which is actually one of the most flourishing fields in theoretical physics today. In the supergravity limit of string theory, this duality outlines a one-to-one correspondence between operators in the CFT on the boundary and the fields of the supergravity theory in the bulk. It could constitute a possible theoretical path towards the building of a theory of quantum gravity, which is the last piece needed to complete the puzzle of unified fundamental interactions. Precisely, we first give an overview of some aspects about supersymmetry, supergravity and AdS/CFT duality, in order to introduce the main two parts of the thesis: On one hand, the study of a particular supergravity theory, which will be referred to as D = 4 generalized AdS-Lorentz deformed supergravity theory, in the presence of a non-trivial boundary (that is when the boundary of spacetime is not thought as set at infinity); on the other hand, the computation of a 1-loop MHV reduced amplitude in N = 2 SCQCD (in D = 4). In the first topic discussed in this thesis, supersymmetry is understood as a local symmetry; indeed, we are dealing with a supergravity theory. On the converse, in the second part of this dissertation, supersymmetry is a global symmetry.

description: Wireless cellular networks evolve towards a heterogeneous infrastructure, featuring multiple types of Base Stations (BSs), such as Femto BSs (FBSs) and Macro BSs (MBSs). A wireless device observes multiple points (BSs) through which it can access the infrastructure and it may choose to receive the downlink (DL) traffic from one BS and send uplink (UL) traffic through another BS. Such a situation is referred to as decoupled DL/UL access. Using the framework of stochastic geometry, we derive the association probability for DL/UL. In order to maximize the average received power, as the relative density of FBSs initially increases, a large fraction of devices chooses decoupled access, i.e. receive from a MBS in DL and transmit through a FBS in UL. We analyze the impact that this type of association has on the average throughput in the system.

description: Eine Vielzahl an Schulklassen besucht jährlich den Nationalpark Donau-Auen. Der Besuch au-ßerschulischer Lernorte ist in den österreichischen Lehrplänen aufgelistet und soll Abwechslung zur alltäglichen schulischen Wissensvermittlung von Kindern schaffen. Die Vermittlung von Themen wie „Natur“ und „Naturschutz“, während einer Exkursion in einem Schutzgebiet, ermöglicht ein besseres Verständnis für Schüler*innen, da ein Bezug zu diesem hergestellt werden kann. Solche Exkursionen sollten im besten Fall vor- und nachbereitet wer-den, um nachhaltige Lernerfolge zu erzielen. Im Unterricht kann einerseits auf Erlebtes zurück-gegriffen werden und andererseits kann ein Verständnis für die oben genannten Themen erzielt werden. Durch eine Umfrage sollen die Interessens- und Erwartungshaltung von Lehrkräften, die bereits eine Exkursion in den Nationalpark Donau-Auen durchgeführt haben, erhoben werden. Mithilfe dieser Ergebnisse soll eine auf die Bedürfnisse und Interessen der Lehrkräfte zugeschnittene Basis für zielgruppenorientierte Unterrichtsmaterialien für die Vor- und Nachbereitung von Ex-kursionen geschaffen werden. Diese Erhebung soll in weiterer Folge auch bei der Entwicklung von Unterrichtskonzepten helfen.
description: A large number of school classes visit the Donau-Auen National Park every year. Visit-ing extracurricular places of learning is listed in the Austrian curricula and creates a setting different to the everyday school knowledge transfer. Excursions should optimally be prepared before and after the visit in order to achieve the best learning results. Moving the topics "nature" and "nature conservation" to out-of-school locations, which allows a hands-on experience of these topics, links them also with the daily life experience of the students. In this way, lessons can be connect-ed to what they have experienced. A survey was conducted to determine the interests and expectations of teachers who have already taken an excursion to the Donau-Auen National Park. With the help of these results, a basis for target group-oriented teaching materials for the preparation and follow-up of excursions will be created. This survey should subsequently help in the development of future teaching concepts.

description: This deliverable describes the ICS-C system portal integration. The EPOS ICS-C portal is indeed the front window of a complex system that provides the end user scientific data aggregated from EPOS Thematic Core Services. In addition to this data level integration and in order to guarantee functional and non-functional requirements defined in synergy with the EPOS communities, the portal offers a number of functionalities, for instance a secure layer for accessing the Data portal (namely Authentication, Authorisation, Accounting Infrastructure - AAAI), that are not built from the ground up, but integrated from existing resource provider. This second level of integration, functionality level integration, is exemplified in the case of AAAI and distributed processing. In the current document we describe how the integration of all assets that compose the EPOS ICS System portal has been carried out. The described work has involved several team from many countries and has created synergies between EPOS technical Work Packages, namely WP6 and WP7, and EPOS community Work Packages, that is to say Wps from 8 to 17. The description of the strategies for managing, interacting and bringing together such a number of stakeholders with different background and even slightly different cultures cannot be dealt with in the framework of this deliverable. However, it might be considered an added value and high-value hidden achievements of the EPOS enterprise.

description: The critical theories for the topological phase transitions of integer quantum Hall states to a trivial insulating state with the same symmetry can be obtained by calculating the ground state entanglement spectrum under a symmetric checkerboard bipartition. In contrast to the gapless edge excitations under the left-right bipartition, a quantum network with bulk gapless excitations naturally emerges at the Brillouin zone center without fine tuning. On a large finite lattice, the resulting critical theory for the $ν=1$ state is the (2+1) dimensional relativistic quantum field theory characterized by a \textit{single} Dirac cone spectrum and a pair of \textit{fractionalized} zero-energy states, while for the $ν=2$ state the critical theory exhibits a parabolic spectrum and no sign of fractionalization in the zero-energy states. A triangular correspondence is established among the bulk topological theory, gapless edge theory, and the critical theory via the ground state entanglement spectrum.

description: In dieser Arbeit wird der Diskurs zum Klimawandel in Österreich erforscht. Auf der Basis von Zeitungsartikeln aus den Jahren 1990 bis 2019, die dem Austrian Media Corpus entnommen sind, soll der Frage nachgegangen werden, welche Änderungen in Hinsicht auf Lexik, Akteur*innen und Argumentationsmuster im Diskurs stattgefunden haben. Hierzu kommen computerlinguistische quantitative Methoden zum Einsatz, die auf intratextueller Ebene Kollokationen, auf Akteursebene Keywords sowie auf transtextueller Ebene Keywords in Context identifizieren. Damit wird der Frage nachgegangen, welche Implikationen die Lexik zur Beschreibung des Phänomens birgt, wer es schafft, sich im Diskurs Gehör zu verschaffen und welche Topoi textübergreifend im printmedialen Diskurs vorkommen. Dabei zeigt sich, dass der Diskurs in unterschiedlichen Dekaden und Ressorts unterschiedliche Schwerpunkte hat, sowie dass einer anfänglichen Konsolidierung eine größere Vielfalt in Themen und Akteur*innen folgt. Auch bei den Topoi konnten neben solchen, die zeit- und themenübergreifen vorherrschend sind, auch spezifische Muster in Dekaden und Ressorts festgestellt werden.
description: This thesis deals with the discourse about climate change in Austria. The aim is to answer questions about how lexical patterns, actors and lines of reasoning have changed. The database consists of print articles published between 1990 and 2019 which are taken from the Austrian Media Corpus. Collocations, keywords and keywords in context, created by using quantitative computer linguistic methods, are used to investigate 1. the implications of lexical patterns; 2. who manages to make themselves heard and 3. which lines of reasoning occur throughout the articles. It shows that the discourse about climate change has different characteristics in different decades and spheres. Also, after a period of consolidation in the beginning, the actors and topics become more diverse. Additionally, some lines of reasoning have shown to be prominent regardless of time and spheres, while others can be seen as characteristic for different decades and specific topics.

Creators: name: McAllister, Luke
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: Sea cage aquaculture can alter the spatial distribution of wild fish populations; however, little is known about the dietary habits and subsequent effects on wild fish. In this thesis, I used stable isotopes δ¹³C and δ¹⁵N values and proportions of vegetable oil-based fatty acids (VOFAs) to investigate the dietary habits of wild cage-associated Atlantic cod Gadus morhua and Atlantic redfish Sebastes fasciatus. Furthermore, I compared the length, weight and condition of cage-associated G. morhua ages 2-4 years old to reference sites within the local division and outside divisions removed from aquaculture, and used VOFAs as biomarkers for waste feed consumption to identify any role(s) in explaining differences in length, weight and condition among age classes. Juvenile G. morhua captured around sea cages had depleted δ¹³C and δ¹⁵N values and elevated proportions of VOFAs consistent with waste feed consumption and sea cage residency, whereas differences in δ¹³C, δ¹⁵N, and VOFAs in cage-associated adult G. morhua and S. fasciatus were predominately absent. Interestingly, waste feed consumption by age 2 cage-associated G. morhua resulted in lower condition than age 2 G.morhua from the local reference division; however, age 4 cage-associated G. morhuawere longer and heavier than the local reference division, despite no evidence to support direct or indirect waste-feed consumption. Overall, the results of this thesis suggest that δ¹³C, δ¹⁵N and VOFAs are suitable biomarkers for tracing sea cage residency and dietary habits of cage-associated wild fish, but waste feed consumption patterns and subsequent effects on wild fish were paradoxical and dependent on species and life stage.

description: The ratio of the production cross sections times branching fractions (sigma(Bc+) B(Bc+ to J/psi pi+))/ (sigma(B+) B(B+ to J/psi K+)) is studied in proton-proton collisions at a center-of-mass energy of 7 TeV with the CMS detector at the LHC. The kinematic region investigated requires Bc+/- and B+/- mesons with transverse momentum pt > 15 GeV and rapidity abs(y) < 1.6. The data sample corresponds to an integrated luminosity of 5.1 inverse femtobarns. The ratio is determined to be [0.48 +/- 0.05 (stat) +/- 0.03 (syst) +/- 0.05 (tau_{Bc})]% The J/psi pi+/- pi+/- pi-/+ decay mode is also observed in the same data sample. Using a model-independent method developed to measure the efficiency given the presence of resonant behaviour in the three-pion system, the ratio of the branching fractions B(Bc+/- to J/psi pi+/- pi+/- pi-/+) / B(Bc+/- to J/psi pi+/-) is measured to be 2.55 +/- 0.80 (stat) +/- 0.33 (syst) +0.04/-0.01 (tau[Bc+]), consistent with the previous LHCb result.

description: Über die Problematisierung von Übersetzung respektive Transformation wird versucht zu veranschaulichen, welchen Stellenwert Übersetzung und Transformation in den Positionen von Meder, Jörissen/Marotzki und Bettinger einnehmen, um anschließend ein Verständnis hinsichtlich des Zusammenhangs von Übersetzung und Transformation generieren zu können. Medien und damit auch Sprache agieren als Vermittler zwischen Ich und Welt. Ein Verstehen respektive Nichtverstehen ist an Übersetzungsleistungen geknüpft. Es scheint, dass es der Übersetzungsleistung als das essenzielle auslösende Momentum bedarf, damit Transformationsprozesse stattfinden können. Der vorliegende Artikel ist als eine Zusammenfassung der Masterthesis Bildung – Medien – Transformation. Auf den Spuren des Transformations- und Übersetzungsbegriffs in der Medienbildung (Oberneder 2022) zu verstehen.

description: In this paper we analyse the asymptotic behaviour of some nonlocal diffusion problems with local reaction term in general metric measure spaces. We find certain classes of nonlinear terms, including logistic type terms, for which solutions are globally defined with initial data in Lebesgue spaces. We prove solutions satisfy maximum and comparison principles and give sign conditions to ensure global asymptotic bounds for large times. We also prove that these problems possess extremal ordered equilibria and solutions, asymptotically, enter in between these equilibria. Finally we give conditions for a unique positive stationary solution that is globally asymptotically stable for nonnegative initial data. A detailed analysis is performed for logistic type nonlinearities. As the model we consider here lack of smoothing effect, important focus is payed along the whole paper on differences in the results with respect to problems with local diffusion, like the Laplacian operator.
title: Heterogenität im Mathematikunterricht in Bezug auf das Lösen von Gleichungen bei Schüler*innen mit bzw. ohne Migrationshintergrund
Creators: name: Tiefengraber, Thomas
Year: 2021

description: Heterogenität im Mathematikunterricht ist ein sehr häufig diskutiertes Thema im Kontext Schule, welches immer mehr an Bedeutung gewinnt. Seit einigen Jahren wird dabei ein bestimmter Aspekt als entscheidender Faktor in diesem Diskurs betrachtet: der Migrationshintergrund der Kinder. Ausgehend von einigen statistischen Kennzahlen und Daten sowie verschiedensten Begriffserklärungen im theoretischen Teil, soll im Rahmen dieser Masterarbeit durch eine geplante wissenschaftliche Erhebung an zwei Mittelschulen versucht werden klarzustellen, ob es tatsächlich Unterschiede in Bezug auf die Lösekompetenz von Gleichungen bei Schüler*innen mit bzw. ohne Migrationshintergrund gibt, und wenn ja, wie groß diese Unterschiede auch sind. Dazu wurde mit 117 burgenländischen bzw. wiener Schüler*innen im Alter zwischen zwölf und 15 Jahren eine Testung durchgeführt, in der Gleichungen und Textaufgaben gelöst werden mussten. Die Ergebnisse zeigen, dass es keine Unterschiede bzgl. der Lösekompetenz zwischen den Schüler*innen mit bzw. ohne Migrationshintergrund gibt, allerdings konnte festgestellt werden, dass Textaufgaben schlechter gelöst werden als andere Gleichungen.

description: We propose a computational method to measure and visualize interrelationships among any number of DNA sequences allowing, for example, the examination of hundreds or thousands of complete mitochondrial genomes. An "image distance" is computed for each pair of graphical representations of DNA sequences, and the distances are visualized as a Molecular Distance Map: Each point on the map represents a DNA sequence, and the spatial proximity between any two points reflects the degree of structural similarity between the corresponding sequences. The graphical representation of DNA sequences utilized, Chaos Game Representation (CGR), is genome- and species-specific and can thus act as a genomic signature. Consequently, Molecular Distance Maps could inform species identification, taxonomic classifications and, to a certain extent, evolutionary history. The image distance employed, Structural Dissimilarity Index (DSSIM), implicitly compares the occurrences of oligomers of length up to $k$ (herein $k=9$) in DNA sequences. We computed DSSIM distances for more than 5 million pairs of complete mitochondrial genomes, and used Multi-Dimensional Scaling (MDS) to obtain Molecular Distance Maps that visually display the sequence relatedness in various subsets, at different taxonomic levels. This general-purpose method does not require DNA sequence homology and can thus be used to compare similar or vastly different DNA sequences, genomic or computer-generated, of the same or different lengths. We illustrate potential uses of this approach by applying it to several taxonomic subsets: phylum Vertebrata, (super)kingdom Protista, classes Amphibia-Insecta-Mammalia, class Amphibia, and order Primates. This analysis of an extensive dataset confirms that the oligomer composition of full mtDNA sequences can be a source of taxonomic information.

description: One of the central appealing properties of magnetic gels and elastomers is that their elastic moduli can reversibly be adjusted from outside by applying magnetic fields. The impact of the internal magnetic particle distribution on this effect has been outlined and analyzed theoretically. In most cases, however, affine sample deformations are studied and often regular particle arrangements are considered. Here we challenge these two major simplifications by a systematic approach using a minimal dipole-spring model. Starting from different regular lattices, we take into account increasingly randomized structures, until we finally investigate an irregular texture taken from a real experimental sample. On the one hand, we find that the elastic tunability qualitatively depends on the structural properties, here in two spatial dimensions. On the other hand, we demonstrate that the assumption of affine deformations leads to increasingly erroneous results the more realistic the particle distribution becomes. Understanding the consequences of the assumptions made in the modeling process is important on our way to support an improved design of these fascinating materials.

On the existence of solutions for a parabolic-elliptic chemotaxis model with flux limitation and logistic source

description: In this paper we study the existence of solutions of a parabolic-elliptic system of partial differential equations describing the behaviour of a biological species $u$ and a chemical stimulus $v$ in a bounded and regular domain $Ω$ of $\mathbb{R}^N$. The equation for $u$ is a parabolic equation with a nonlinear second order term of chemotaxis type with flux limitation as $ -χdiv (u |\nabla ψ|^{p-2} \nabla v)$, for $p>1$. The chemical substance distribution $v$ satisfies the elliptic equation $-Δv+v=u$. The evolution of $u$ is also determined by a logistic type growth term $μu(1-u)$. The system is studied under homogeneous Neumann boundary conditions. The main result of the article is the existence of uniformly bounded solutions for $p<3/2$ and any $N\ge 2$.

description: We investigate the differences in the dynamics of the ultrafast photo-induced metal-insulator transition (MIT) of two VO$_2$ thin films deposited on different substrates, TiO$_2$ and Al$_2$O$_3$, and in particular the temperature dependence of the threshold laser fluence values required to induce various MIT stages in a wide range of sample temperatures (150 K - 320 K). We identified that, although the general pattern of MIT evolution was similar for the two samples, there were several differences. Most notably, the threshold values of laser fluence required to reach the transition to a fully metallic phase in the VO$_2$ film on the TiO$_2$ substrate were nearly constant in the range of temperatures considered, whereas the VO$_2$/Al$_2$O$_3$ sample showed clear temperature dependence. Our analysis qualitatively connects such behavior to the structural differences in the two VO$_2$ films.

Rezension: "Schwarze Spiegel" von Arno Schmidt und Mahler
Creators: name: Ballhausen, Thomas
Publisher: name: Medienimpulse

description: Der österreichische Künstler Mahler stellt sich mit seinen eigenwilligen, überaus gelungenen Adaptionen literarischer Werke (z.B. Thomas Bernhard, Robert Musil, Marcel Proust) in eine innerhalb des Mediums Comic lange historische Tradition, gleichzeitig gelingt es ihm in diesen Arbeiten die Spezifika seiner erzählerischen und zeichnerischen Erzählweise zu erhalten. Neustes Beispiel aus dieser Reihe von Veröffentlichungen ist die Bearbeitung der Erzählung Schwarze Spiegel (1951) des deutschen Autors Arno Schmidt (1914-1979), in dessen umfangreichen Werk apokalyptische Settings vielfach nachweisbar sind. Die Wahl von Schwarze Spiegel – ein Text, der ja auch in kommentierten Lesefassungen für den Einsatz im Unterricht vorliegt – erweist sich für Mahlers Herangehensweise dabei als besonders glücklich: Schmidts grimmige, aber nicht humorlose Vorlage geht formal wie auch inhaltlich ideal mit Mahlers vorsätzlich reduziertem Stil zusammen. Die vorliegende Adaption erlaubt somit nicht nur eine Begegnung mit Mahlers kondensierter künstlerischer Herangehensweise, sondern auch eine Wiederbegegnung mit einem Text Arno Schmidts, der ja längst als Klassiker der deutschsprachigen Literatur gelten muss.

description: We demonstrate that the synchronization of an array of electrically coupled spin torque nano-oscillators (STNO) modelled by Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equation can be enhanced appreciably in the presence of a common external microwave magnetic field. The applied microwave magnetic field stabilizes and enhances the regions of synchronization in the parameter space of our analysis, where the oscillators are exhibiting synchronized oscillations thereby emitting improved microwave power. To characterize the synchronized oscillations we have calculated the locking range in the domain of external source frequency.
