description: The analytic properties of the ground state resonance energy E(g) of the cubic potential are investigated as a function of the complex coupling parameter g. We explicitly show that it is possible to analytically continue E(g) by means of a resummed strong coupling expansion, to the second sheet of the Riemann surface, and we observe a merging of resonance and antiresonance eigenvalues at a critical point along the line arg(g) = 5 pi/4. In addition, we investigate the convergence of the resummed weak-coupling expansion in the strong coupling regime, by means of various modifications of order-dependent mappings (ODM), that take special properties of the cubic potential into account. The various ODM are adapted to different regimes of the coupling constant. We also determine a large number of terms of the strong coupling expansion by resumming the weak-coupling expansion using the ODM, demonstrating the interpolation between the two regimes made possible by this summation method.

description: Die Studie dokumentiert den Stand der Digitalisierung im Schulsystem aus der Perspektive von Lehrkräften. Grundlage bildet eine bundesweit repräsentative Befragung von 2.750 Lehrkräften an Gesamtschulen, Gymnasien und vergleichbaren Schulen der Sekundarstufe I und II in Deutschland. Die Lehrkräfte beschreiben ihre Nutzung digitaler Medien und Techniken und die Rahmenbedingungen an ihrer Schule – wobei ein Vergleich des Standes Februar 2021 mit der Situation vor der Corona‐Pandemie 2020 gezogen wird. Erhoben wird auf dieser Basis auch die Selbsteinschätzung zu ihren digitalen Kompetenzen, die Arbeitszeit und Arbeitsbelastung sowie das Ausmaß des digitalen Stresses. Die Studie präsentiert die Ergebnisse und vergleicht sie mit früheren, nationalen und internationalen Studienergebnissen. Anhand von differenzierten Analysen kommt sie zu vier zentralen Befunden: Erstens hat 2020/2021 eine forcierte Digitalisierung an deutschen Schulen stattgefunden, die sehr stark durch technische ad‐hoc‐Lösungen zur Sicherung des Fernlernens und Wechselunterrichts und andere Basis‐Lösungen geprägt ist – aber kaum durch eine weiterführende Praxis des digitalen Lehrens und Lernens. Zweitens hat dies die Arbeitsbedingungen (Arbeitszeit, Arbeitsbelastung, Technostress) für Lehrkräfte in der Krisensituation sehr deutlich verändert. Drittens sind die digitalen Kompetenzen sehr unterschiedlich ausgeprägt, viele Lehrkräfte stehen vor großen Herausforderungen. Neben der organisierten Weiterbildung spielen entwicklungsförderliche Rahmenbedingungen an den Schulen für die Kompetenzentwicklung eine zentrale Rolle. Viertens existiert eine digitale Spaltung zwischen den Schulen in Deutschland, die erhebliche Unterschiede in der Arbeitssituation und den beruflichen Entwicklungsmöglichkeiten von Lehrkräften bedingt – aber auch für die Bildungschancen der Schülerinnen und Schüler ein Problem darstellt.

description: Exponential integrators are a class of numerical methods for stiff systems of differential equations which require the computation of products of so-called matrix phi-functions and vectors. In this thesis, we consider the approximation of these matrix functions times some vector by rational and extended Krylov subspace methods. For arbitrary matrices with a field of values in the left complex half-plane, a uniform approximation is obtained that predicts a sublinear convergence.

description: Experimental progress in the study of strongly interacting ultracold atoms has recently allowed the observation of Efimov trimers. We study theoretically a non-conventional observable for these trimer states, that may be accessed experimentally, the momentum distribution n(k) of the constitutive bosonic particles. The large momentum part of the distribution is particularly intriguing: In addition to the expected 1/k^4 tail associated to contact interactions, it exhibits a subleading tail 1/k^5 which is a hall-mark of Efimov physics and leads to a breakdown of a previously proposed expression of the energy as a functional of the momentum distribution.

description: The interplay of Coulomb repulsion and geometrical frustration on charge-driven quantum phase transitions is explored. The ground state phase diagram of an extended Hubbard model on an anisotropic triangular lattice relevant to quarter-filled layered organic materials contains homogeneous metal, 'pinball' and three-fold charge ordered metallic phases. The stability of the 'pinball' phase occurring for strong Coulomb repulsions is found to be strongly influenced by geometrical frustration. A comparison with a spinless model reproduces the transition from the homogeneous metallic phase to a pinball liquid, which indicates that the spin correlations should play a much smaller role than the charge correlations in the metallic phase close to the charge ordering transition. Spin degeneracy is, however, essential to describe the dependence of the system on geometrical frustration. Based on finite temperature Lanczos diagonalization we find that the effective Fermi temperature scale, T*, of the homogeneous metal vanishes at the quantum phase transition to the ordered metallic phase driven by the Coulomb repulsion. Above this temperature scale 'bad' metallic behavior is found which is robust against geometrical frustration in general. Quantum critical phenomena are not found whenever nesting of the Fermi surface is strong, possibly indicating a first order transition instead. 'Reentrant' behavior in the phase diagram is encountered whenever the 2kF-CDW instability competes with the Coulomb driven three-fold charge order transition. The relevance of our results to the family of quarter-filled materials: theta-(BEDT-TTF)2X is discussed.

description: We show how quark-disconnected and quark-connected contributions to hadronic n-point functions can be written as independent correlators for which one can derive expressions in partially quenched chiral effective theory. As an example we apply the idea to the case of the hadronic vacuum polarisation. In particular, we consider the cases of the Nf = 2 theory without and with a partially quenched strange quark and also the Nf = 2 + 1 theory. In the latter two cases a parameter-free prediction for the disconnected contribution at NLO in the effective theory is given. Finally we show how twisted boundary conditions can then be used in lattice QCD to improve the q^2 resolution in the connected contributions even when flavour singlet operators are considered.

The Spring 2023 issue presents research and guidance on topics related to student self-reflection, participatory learning, and returning to the in-person learning following the COVID-19 pandemic. The first article takes a critical approach to understanding pedagogy with adult learners by involving students in the creation of course syllabi as a way to challenge ideologies related the roles of instructor and students. The second article blends research and narrative to explore how the experiences of the COVID-19 shift to online learning can be translated to in-person learning environments to redefine what participation looks like and to advance faculty collaboration. The third article continues to explore how the COVID-19 pandemic can lead to opportunities for improved course development and delivery as faculty and students return to the classroom, particularly in the areas of communication, equity, and inclusion. The fourth article presents a selection of prompts used to promote student learning through written reflection tasks and describes how such tasks can be applied to various teaching contexts. The fifth article describes the use of a digital poverty simulation with business students and examines how the activity affected the students' attitudes toward poverty.

description: The output of an association rule miner is often huge in practice. This is why several concise lossless representations have been proposed, such as the "essential" or "representative" rules. We revisit the algorithm given by Kryszkiewicz (Int. Symp. Intelligent Data Analysis 2001, Springer-Verlag LNCS 2189, 350-359) for mining representative rules. We show that its output is sometimes incomplete, due to an oversight in its mathematical validation. We propose alternative complete generators and we extend the approach to an existing closure-aware basis similar to, and often smaller than, the representative rules, namely the basis B*.

subject: likelihood of confusion
subject: machine learning

description: Over the past years, the number of trademark application has risen continuously. To make it easier for trademark owners to protect their trademarks' territory and for trademark applicants to know if their trademark is likely to be refused, an automated and reliable tool is needed to compare two trademarks and their respective goods and services. Most of the existing services offering a similarity search just consider the spelling of the trademarks’ names, which is insufficient to assess likelihood of confusion. For this reason, this thesis introduces the concept of a trademark management system, TrademarkML. TrademarkML faciliates tasks like trademark monitoring and searching for conflicting trademarks by automatically classifying trademark pairs. TrademarkML employs state-of-the-art methods for extracting meaningful features for the comparison of trademarks in various aspects. Exhaustive feature selection is then used to tune random forests and support vector machines to all feature combinations. TrademarkML achieves an F1-score of 88% for word marks and 81% for figurative marks, a recall of 98% for word marks and 84% for figurative marks, and a precision of 80% for word marks and 77% for figurative marks. Overall, TrademarkML performs better on word mark data by 6.8% on average for each metric. None of the top-performing models uses a feature for measuring the similarity of goods and services. This makes it impossible to correctly predict partially upheld oppositions. A larger dataset and more meaningful features are required to overcome this issue.

Transformative participatory approaches in education are positioned to challenge traditional models where instructors bear all responsibility for knowledge creation and learners are passive recipients of knowledge. The promotion of participatory learning and critical pedagogy is essential to helping professionals seeking to understand oppressive structural barriers and employing strategies to dismantle these structures. This article describes a participatory approach undertaken to guide learners through an exercise to co-create syllabus content in a graduate social work course. Learners identified three themes, concerns, fears, and problems, related to the course material. Learners were also asked to think about how they could address the three themes to apply new information to problem solve. Through the syllabus cloud activity, learners shaped course content, decided on the format to deliver content, and applied their status as adult learners in an intentional way. As educators prepare to critically and intentionally dismantle aspects of the learning milieu that may perpetuate systems of oppression, collaborative learning and teaching can help to reduce oppressive practices. Reflections for formative and summative evaluation and future research are discussed.

Recent global events pushed in-person learning to online formats. As K-12 teachers struggled with shifting from in-person to online teaching while adapting and adjusting instruction, and higher education prepared to do the same, two faculty members in a TESOL teacher preparation program joined forces to question assumptions about online teaching, reflect on praxis, and revisit pedagogy and practices through a critical autoethnographic study. Building from adult constructivist learning theory and collegial inquiry, the researchers utilized the pandemic as a stage for innovation and an opportunity to study their own ability, as teacher educators, to adapt and develop in changing circumstances. Researcher journals, course evaluations, student projects, and recorded classes and discussions were analyzed to question assumptions about online pedagogy, perceptions of professors and students, and what innovation could accompany the return to face-to-face learning or hybrid models. This article presents their findings and offers a discussion about the importance of faculty re-envisioning pedagogical practices that move beyond traditional lectures in favor of a more learning-centered classroom which prioritizes problem solving and applying new knowledge in a variety of contexts. Furthermore, the researchers note the importance of collegial inquiry to innovating higher education.

description: We study a coherent superposition of field annihilation and creation operator acting on continuous variable systems and propose its application for quantum state engineering. Specifically, it is investigated how the superposed operation transforms a classical state to a nonclassical one, together with emerging nonclassical effects. We also propose an experimental scheme to implement this elementary coherent operation and discuss its usefulness to produce an arbitrary superposition of number states involving up to two photons.

This Scholarship of Teaching and Learning (SoTL) study examined whether undergraduate business students reported having different attitudes towards poverty after completing SPENT. SPENT is an open-access, digital poverty simulation offered through Urban Ministries of Durham. The author used the Reflexive Thematic Analysis approach (Braun & Clarke, 2006) to analyze 17 student reflection papers. The students were enrolled in an introductory finance course at a small teaching institution in the Southwest. The student reflection paper prompts were based on the four-phase Experiential Learning Model (Kolb, 1984). The author constructed four themes about the students’ attitudes toward poverty: (1) laziness and poor decisions, (2) multiple causes, (3) low wages, and (4) importance of education. This research offers implications for college instructors who use simulations and those who teach about poverty.

description: Access the online Pressbooks version of this article here.
Reflection is a necessary component of learning. Through reflective assignments and tasks, students are given opportunities to evaluate their learning and analyze strategies they use while acquiring and applying course material. Reflections also help students assess and think deeply about the information presented in class and thus better retain it. Through reflecting on their learning, students are also given the opportunity to formulate goals for future improvement. Reflective tasks can be implemented in any classroom, and writing is a powerful tool to do that. This article describes several writing tasks that promote student reflection both on the course material and on their own performance: writing reflective journals, reflections on writing assignments, reflections on teacher and peer feedback, writing-to-learn activities, and letters to the Reviewer.

description: We have developed the formalism necessary to employ the discontinuous-Galerkin approach in general-relativistic hydrodynamics. The formalism is firstly presented in a general 4-dimensional setting and then specialized to the case of spherical symmetry within a 3+1 splitting of spacetime. As a direct application, we have constructed a one-dimensional code, EDGES, which has been used to asses the viability of these methods via a series of tests involving highly relativistic flows in strong gravity. Our results show that discontinuous Galerkin methods are able not only to handle strong relativistic shock waves but, at the same time, to attain very high orders of accuracy and exponential convergence rates in smooth regions of the flow. Given these promising prospects and their affinity with a pseudospectral solution of the Einstein equations, discontinuous Galerkin methods could represent a new paradigm for the accurate numerical modelling in relativistic astrophysics.

So far, 7 missions have been already implemented, for a total of 18 days. In summary, the development and mobility of staff is on track, as many of the missions required some preparation and will be realized in the remainder of the project. A Final report on staff development (D2.4) will be provided at the end of the project (M48).
Spin transfer torque enhancement in dual spin valve in the ballistic regime

description: The spin transfer torque in all-metal dual spin valve, in which two antiparallelly aligned pinned ferromagnetic layers are on the two sides of a free ferromagnetic layer with two thin nonmagnetic spacers in between, is studied in the ballistic regime. It is argued that, similar to the results in the diffusion regime, the spin transfer torque is dramatically enhanced in comparison to that in a conventional spin valve although no spin accumulation exists at the magnetic-nonmagnetic interfaces. Within the Slonczewski's approach, an analytical expression of the torque on the free magnetic layer is obtained, which may serve as a theoretical model for the micromagnetic simulation of the spin dynamics in dual spin valve. Depending on the orientation of free layer and the degree of electron polarization, the spin transfer torque enhancement could be tens times. The general cases when transmission and reflection probabilities of free layer are different from zero or one are also numerically calculated.

In order to achieve this, we construct isomorphisms between associated coalgebras and notice their correspondence with the exponential map. Moreover, we define the notion of the Atiyah class of the Lie pair and show that the Kapranov dg manifold we constructed is linearizable if and only if the Atiyah class vanishes.

description: We report on the observation of triatomic Efimov resonances in an ultracold gas of cesium atoms. Exploiting the wide tunability of interactions resulting from three broad Feshbach resonances in the same spin channel, we measure magnetic-field dependent three-body recombination loss. The positions of the loss resonances yield corresponding values for the three-body parameter, which in universal few-body physics is required to describe three-body phenomena and in particular to fix the spectrum of Efimov states. Our observations show a robust universal behavior with a three-body parameter that stays essentially constant.

description: Σε αυτή την εργασία παρουσιάζεται η θεωρητική προσέγγιση ενός πρωτότυπου συστήματος μετατροπής Ελληνικού κειμένου σε Ελληνική Νοηματική Γλώσσα (GSL). Παρέχεται η λεπτομερής εφαρμογή της συνιστώσας επεξεργασίας γλώσσας ενός συστήματος μετατροπής ελληνικού κειμένου σε GSL, εστιάζοντας στα εγγενή προβλήματα εξαγωγής γνώσης της γραμματικής της νοηματικής γλώσσας (SL) και της εφαρμογής της σε ένα πλαίσιο ανάλυσης. Σχεδιάστηκε ώστε να χρησιμοποιεί μια βάση δεδομένων λεξικού SL με κωδικοποιημένες γνώσεις GSL. Το προτεινόμενο σύστημα έχει σχεδιαστεί αφού έχουν ληφθεί υπόψη τα περισσότερα state-of-the-art συστήματα αυτόματης μετάφρασης ή μετατροπής SL και λαμβάνοντας υπόψη τα πλεονεκτήματα και τα μειονεκτήματά τους. Η συνολική αρχιτεκτονική είναι καινοτόμος αφού άλλα υπάρχοντα συστήματα είτε δεν λαμβάνουν υπόψη το GSL είτε δεν μπορούν να εφαρμοστούν αποτελεσματικά σε προτάσεις αλλά μόνο σε μεμονωμένες λέξεις.
description: The aim of the present thesis was to present a prototype Greek text to Greek Sign Language (GSL) conversion system. The detailed implementation of the language-processing component of a Greek text to GSL conversion system is provided, focusing upon the inherent problems of knowledge elicitation of sign language (SL) grammar and its implementation within a parser framework. It uses an SL dictionary database of coded GSL knowledge. The proposed system has been designed after considering most state-of-the-art SL machine translation or Conversion systems and taking into account their advantages and disadvantages. The overall architecture is innovative since other existing systems either do not consider the GSL or they cannot be effectively applied on sentences but just on single words.

description: Stellar metallicity strongly correlates with the presence of planets and their properties. To check for new correlations between stars and the existence of an orbiting planet, we determine precise stellar parameters for a sample of metal-poor solar-type stars. This sample was observed with the HARPS spectrograph and is part of a program to search for new extrasolar planets. The stellar parameters were determined using an LTE analysis based on equivalent widths (EW) of iron lines and by imposing excitation and ionization equilibrium. The ARES code was used to allow automatic and systematic derivation of the stellar parameters. Precise stellar parameters and metallicities were obtained for 97 low metal-content stars. We also present the derived masses, luminosities, and new parallaxes estimations based on the derived parameters, and compare our spectroscopic parameters with an infra-red flux method calibration to check the consistency of our method in metal poor stars. Both methods seems to give the same effective temperature scale. Finally we present a new calibration for the temperature as a function of \textit{B-V} and [Fe/H]. This was obtained by adding these new metal poor stars in order to increase the range in metallicity for the calibration. The standard deviation of this new calibration is $\sim$ 50 K.

description: A superconducting quantum interference device (SQUID) was prepared on a micron-sized single crystal using a selected growth domain of a thin film of $CeCoIn_5$ grown by molecular beam epitaxy. SQUID voltage oscillations of good quality were obtained as well as interference effects stemming from the individual Josephson microbridges. The transport characteristics in the superconducting state exhibited several peculiarities which we ascribe to the periodic motion of vortices in the microbridges. The temperature dependence of the Josephson critical current shows good correspondence to the Ambegaokar-Baratoff relation, expected for the ideal Josephson junction. The results indicate a promising pathway to identify the type of order parameter in $CeCoIn_5$ by means of phase-sensitive measurements on microbridges.

description: I present results for top quark production in hadronic collisions at LHC and Tevatron energies. The soft-gluon corrections to the differential cross section are resummed at next-to-next-to-leading-logarithm (NNLL) accuracy via the two-loop soft anomalous dimension matrices. Approximate next-to-next-to-leading-order (NNLO) differential and total cross sections are calculated. Detailed theoretical predictions are shown for the t tbar cross section and the top quark p_T distribution at the Tevatron and the LHC.

An investigation of the transition from early intervention to school for children who are deaf or hard of hearing

description: The transition to school is considered an important milestone in early childhood development with implications for later school outcomes. However, it has been largely uninvestigated for children who are deaf or hard of hearing (D/HH). The overarching goal of this dissertation was to examine the transition from specialized early intervention (EI) programs into the school system for children who are D/HH and their families. Study 1 investigated the availability, accessibility and content of information on the transition to school for D/HH children on government, outreach program, EI program and school district websites in British Columbia (B.C.), Canada. Results indicated that the majority of these websites offer little information about the transition to school, particularly in rural areas. Limited accessibility, particularly for individuals with disabilities or with lower English literacy was noted. Study 2 investigated the transition from the perspective of administrators and directors from EI, outreach, and school-based programs for D/HH children. Using the enhanced critical incident technique (ECIT), 146 incidents were extracted from 10 interviews and sorted into 10 helping, nine hindering and five wish list categories. Findings highlight the importance of communication and information exchange among stakeholders to provide a smooth transition to school for D/HH children. To further investigate the communication that occurs and the relationships that develop among stakeholders during D/HH children’s transition to school, Study 3 used activity theory as a framework to examine the means by which stakeholders (parents, EI providers, and teachers of the deaf) communicated, and the topics that they discussed. Results add support for families’ need for information about their child’s educational program, and use of personalized, high-intensity transition practices to support children and their families through the transition process. The overall findings of this dissertation lend support to the Ecological and Dynamic Model of Transition (Rimm-Kaufman & Pianta, 2000), which conceptualizes the transition to school as being influenced by a pattern of interactions between the individuals, groups, and institutions connected to the child. Future directions for research and practice are discussed.
Type IA supernovae from very long delayed explosion of core - WD merger

description: We study the spinning down time scale of rapidly rotating white dwarfs (WDs) in the frame of the core-degenerate (CD) scenario for type Ia supernovae (SNe Ia). In the CD scenario the Chandrasekhar or super-Chandrasekhar mass WD is formed at the termination of the common envelope phase or during the planetary nebula phase, from a merger of a WD companion with the hot core of a massive asymptotic giant branch star. In the CD scenario the rapidly rotating WD is formed shortly after the stellar formation episode, and the delay from stellar formation to explosion is basically determined by the spin-down time of the rapidly rotating merger remnant. We find that gravitational radiation is inefficient in spinning down WDs, while the magneto-dipole radiation torque can lead to delay times that are required to explain SNe Ia.

Energy current magnification in coupled oscillator loops

description: Motivated by studies on current magnification in quantum mesoscopic systems we consider sound and heat transmission in classical models of oscillator chains. A loop of coupled oscillators is connected to two leads through which one can either transmit monochromatic waves or white noise signal from heat baths. We look for the possibility of current magnification in this system due to some asymmetry introduced between the two arms in the loop. We find that current magnification is indeed obtained for particular frequency ranges. However the integrated current shows the effect only in the presence of a pinning potential for the atoms in the leads. We also study the effect of anharmonicity on current magnification.

description: We derive analytic expressions for the possibility, probability, and expected size of global spreading events starting from a single infected seed for a broad collection of contagion processes acting on random networks with both directed and undirected edges and arbitrary degree-degree correlations. Our work extends previous theoretical developments for the undirected case, and we provide numerical support for our findings by investigating an example class of networks for which we are able to obtain closed-form expressions.
