description: Difference arrays are used in applications such as software testing, authentication codes and data compression. Pseudo-orthogonal Latin squares are used in experimental designs. A special class of pseudo-orthogonal Latin squares are the mutually nearly orthogonal Latin squares (MNOLS) first discussed in 2002, with general constructions given in 2007. In this paper we develop row complete MNOLS from difference covering arrays. We will use this connection to settle the spectrum question for sets of 3 mutually pseudo-orthogonal Latin squares of even order, for all but the order 146.

description: We present the analysis of four first overtone RR Lyrae stars observed with the Kepler space telescope, based on data obtained over nearly 2.5yr. All four stars are found to be multiperiodic. The strongest secondary mode with frequency f_2 has an amplitude of a few mmag, 20 - 45 times lower than the main radial mode with frequency f_1. The two oscillations have a period ratio of P_2/P_1 = 0.612 - 0.632 that cannot be reproduced by any two radial modes. Thus, the secondary mode is nonradial. Modes yielding similar period ratios have also recently been discovered in other variables of the RRc and RRd types. These objects form a homogenous group and constitute a new class of multimode RR Lyrae pulsators, analogous to a similar class of multimode classical Cepheids in the Magellanic Clouds. Because a secondary mode with P_2/P_1 ~ 0.61 is found in almost every RRc and RRd star observed from space, this form of multiperiodicity must be common. In all four Kepler RRc stars studied, we find subharmonics of f_2 at ~1/2 f_2 and at ~3/2 f_2. This is a signature of period doubling of the secondary oscillation, and is the first detection of period doubling in RRc stars. The amplitudes and phases of f_2 and its subharmonics are variable on a timescale of 10 - 200d. The dominant radial mode also shows variations on the same timescale, but with much smaller amplitude. In three Kepler RRc stars we detect additional periodicities, with amplitudes below 1mmag, that must correspond to nonradial g-modes. Such modes never before have been observed in RR Lyrae variables.

A partir de observações a olho nu, não se constatou alteração de cor em relação à exposição ultravioleta. Em razão disso, foi essencial a caracterização da neoformação cristalina presente nas amostras com o intuído de compreender sua composição e realizar análises complementares a fim de neutralizar sua formação, de modo a proporcionar a estabilidade do pó obtido, para a produção de um pigmento eficaz na aplicação de processos restaurativos.

description: Die Darstellung erläutert und illustriert ein Verfahren, die zeitliche Abfolge von Texten ohne Zuhilfenahme äußerer Daten zu bestimmen. Indem die Texte als aktuales Sprechereignis verstanden werden, treten sie in ihrer jeweiligen authentischen Gegenwart in den Blick. Getragen von ihrem originären Sprecher in actu, setzen sie – in dessen elementarer Funktion – ein verstehendes Äquivalent frei, den originären Rezipienten. Als Gegenüber des Sprecher-Subjekts, zugleich aber nur aus diesem ableitbar, bekundet er eine räumliche Gegenwart, die zugleich zeitliche Gegenwart beglaubigt und mit dieser notwendig verfällt. – Das Verfahren erweist die Vorstellung vom Alter des griechischen Alphabets und damit zugleich die seit 1952 herrschende Deutung der bronzezeitlichen Linear-B-Schrift als revisionsbedürftig. Der komplette Datenbestand mit Suchfunktion ist online zugänglich unter: http://hdl.handle.net/10900/97631
description: The article illustrates a method for determining the temporal sequence of texts without the use of external data. By interpreting the texts as an instant speech event, one can focus on their authentic presence. As they are communicated by the speaker of origin in actu, they – in their most elementary function – construct a comprehending equivalent, i.e. the original addressee. He is a vis à vis of the speaking subject and simultaneously, however, derived from the speaking subject. In this capacity, he possesses a temporal and consequently a spatial presence, which with the former necessarily decays. - The method provides evidence that both the conception of the age of the Greek alphabet and the since 1952 prevailing interpretation of the Bronze-age Linear B script stand in need of revision.

description: In this paper we consider the reproducing kernel thesis for boundedness and compactness for operators on $\ell^2$--valued Bergman-type spaces. This paper generalizes many well--known results about classical function spaces to their $\ell^2$--valued versions. In particular, the results in this paper apply to the weighted $\ell^2$--valued Bergman space on the unit ball, the unit polydisc and, more generally to weighted Fock spaces.

description: We probe the transition between superfluid and Bose glass phases using quantum quenches of disorder in an ultracold atomic lattice gas that realizes the disordered Bose-Hubbard model. Measurements of excitations generated by the quench exhibit threshold behavior in the disorder strength indicative of a phase transition. Ab-initio quantum Monte Carlo simulations confirm that the appearance of excitations coincides with the equilibrium superfluid--Bose-glass phase boundary at different lattice potential depths. By varying the quench time, we demonstrate the disappearance of an adiabatic timescale compared with microscopic parameters in the BG regime.

title: Optical springs to create macroscopic optical traps and negative inertia for gravitational wave detectors
Creators: name: Wright, Jennifer L.
Publisher: name: University of Glasgow
Year: 2022

description: This thesis investigates the phenomena of negative inertia and optical traps, and endeavours to implement them in an interferometer system that is a prototype of a gravitational wave detector arm cavity and uses similar control techniques and apparatus. Chapter 1 discusses gravitational waves and how they are produced. It then moves onto the basic design of current gravitational wave detectors and the main noise sources that are required to be taken into account when engineering the detector. Lastly, it concludes by discussing future gravitational wave detector designs and how this work might inform these. In Chapter 2 the theoretical underpinnings of optical springs are discussed. The chapter moves on to discuss the quantum noise of an interferometer and how optical springs change this. An expression for the optical spring constant is given, and then the thesis discusses how the frequency dependence of this quantity complicates obtaining analytical expressions. A review of optical spring stability in a Fabry-Perot interferometer is then provided. Systems with multiple optical springs that would be interesting to investigate in the current work are discussed, then a justification is given for investigating these effects and optical springs in general, in the light of the current state of the field. The layout of the experimental apparatus is laid out in Chapter 3. There are two experimental cavities which share a common mirror, the central test mass (CTM), and two input lasers. The setup of the optical systems is discussed first, then the layout of the suspensions, then how the electronic control of the lasers and experimental cavities is achieved. Chapter 4 lays out the procedure for calibrating the experiment and carrying it out. The determination of the cavity circulating power is discussed mathematically. Then the setup of the cavity simulation, the experimental calibration of the two cavity measurement process, and finally the calibration of spring detuning in the main experimental cavity is described. Results of the main thesis experiments are discussed in Chapter 5. Measurements using simple optomechanical systems are discussed first, then more complex measurements are described. Finally, evidence for both negative inertia and trapping is discussed. The conclusion given in Chapter 6 sums up the tasks achieved in the thesis work and the limitations of the results obtained are discussed. Some suggestions for further work are given.

A Gaussian Treatment for the Friction Issue of Lennard-Jones Potential in Layered Materials: Application to Friction between Graphene, MoS2 and Black Phosphorus

description: The Lennard-Jones potential is widely used to describe the interlayer interactions within layered materials like graphene. However, it is also widely known that this potential strongly underestimates the frictional properties for layered materials. Here we propose to supplement the Lennard-Jones potential by a Gaussian-type potential, which enables more accurate calculations of the frictional properties of two-dimensional layered materials. Furthermore, the Gaussian potential is computationally simple as it introduces only one additional potential parameter that is determined by the interlayer shear mode in the layered structure. The resulting Lennard-Jones-Gaussian potential is applied to compute the interlayer cohesive energy and frictional energy for graphene, MoS2, black phosphorus, and their heterostructures.

description: Mean-field systems have been previously derived for networks of coupled, two-dimensional, integrate-and-fire neurons such as the Izhikevich, adapting exponential (AdEx) and quartic integrate and fire (QIF), among others. Unfortunately, the mean-field systems have a degree of frequency error and the networks analyzed often do not include noise when there is adaptation. Here, we derive a one-dimensional partial differential equation (PDE) approximation for the marginal voltage density under a first order moment closure for coupled networks of integrate-and-fire neurons with white noise inputs. The PDE has substantially less frequency error than the mean-field system, and provides a great deal more information, at the cost of analytical tractability. The convergence properties of the mean-field system in the low noise limit are elucidated. A novel method for the analysis of the stability of the asynchronous tonic firing solution is also presented and implemented. Unlike previous attempts at stability analysis with these network types, information about the marginal densities of the adaptation variables is used. This method can in principle be applied to other systems with nonlinear partial differential equations.

Towards Mining Creative Thinking Patterns from Educational Data

Subjects: Other education not elsewhere classified

description: Creativity, i.e., the process of generating and developing fresh and original ideas or products that are useful or effective, is a valuable skill in a variety of domains. Creativity is called an essential 21st-century skill that should be taught in schools. The use of educational technology to promote creativity is an active study field, as evidenced by several studies linking creativity in the classroom to beneficial learning outcomes. Despite the burgeoning body of research on adaptive technology for education, mining creative thinking patterns from educational data remains a challenging task. In this thesis, to address this challenge, we put the first step towards formalizing the educational knowledge by constructing a domain-specific Knowledge Base to identify essential concepts, facts, and assumptions in identifying creative patterns. We then introduce a pipeline to contextualize the raw educational data, such as assessments and class activities. Finally, we present a rule-based approach to learn from the Knowledge Base, and facilitate mining creative thinking patterns from contextualized data and knowledge. We evaluate our approach with real-world datasets and highlight how the proposed pipeline can help instructors understand creative thinking patterns from students’ activities and assessment tasks.

description: NICMOS 2 observations are crucial for constraining distances to most of the existing sample of z > 1 SNe Ia. Unlike the conventional calibration programs, these observations involve long exposure times and low count rates. Reciprocity failure is known to exist in HgCdTe devices and a correction for this effect has already been implemented for high and medium count-rates. However observations at faint count-rates rely on extrapolations. Here instead, we provide a new zeropoint calibration directly applicable to faint sources. This is obtained via inter-calibration of NIC2 F110W/F160W with WFC3 in the low count-rate regime using z ~ 1 elliptical galaxies as tertiary calibrators. These objects have relatively simple near-IR SEDs, uniform colors, and their extended nature gives superior signal-to-noise at the same count rate than would stars. The use of extended objects also allows greater tolerances on PSF profiles. We find ST magnitude zeropoints (after the installation of the NICMOS cooling system, NCS) of 25.296 +- 0.022 for F110W and 25.803 +- 0.023 for F160W, both in agreement with the calibration extrapolated from count-rates 1,000 times larger (25.262 and 25.799). Before the installation of the NCS, we find 24.843 +- 0.025 for F110W and 25.498 +- 0.021 for F160W, also in agreement with the high-count-rate calibration (24.815 and 25.470). We also check the standard bandpasses of WFC3 and NICMOS 2 using a range of stars and galaxies at different colors and find mild tension for WFC3, limiting the accuracy of the zeropoints. To avoid human bias, our cross-calibration was "blinded" in that the fitted zeropoint differences were hidden until the analysis was finalized.

description: Spin-orbit torques are studied in Ta/TbFeCo patterned structures with a bulk perpendicular magnetic anisotropy (bulk-PMA) for the first time. The current-induced magnetization switching is investigated in the presence of a perpendicular, longitudinal, or transverse field. In order to rule out Joule heating effect, switching of the magnetization is also demonstrated using current pulses. It is found that the anti-damping torque correlated with spin Hall effect is very strong, and a spin Hall angle of about 0.12 is obtained. The field-like torque related with Rashba effect is negligible in this structure suggesting that the interface play a significant role in Rashba-like torque.

description: We present a theory which explains how to achieve an enhancement of nonlinear effects in a thin layer of nonlinear medium by involving a planar periodic structure specially designed to bear a trapped-mode resonant regime. In particular, the possibility of a nonlinear thin metamaterial to produce the bistable response at a relatively low input intensity due to a large quality factor of the trapped-mode resonance is shown. Also a simple design of an all-dielectric low-loss silicon-based planar metamaterial which can provide an extremely sharp resonant reflection and transmission is proposed. The designed metamaterial is envisioned for aggregating with a pumped active medium to achieve an enhancement of quantum dots luminescence and to produce an all-dielectric analog of a 'lasing spaser'.

description: The mathematical model of a steadily propagating Saffman-Taylor finger in a Hele-Shaw channel has applications to two-dimensional interacting streamer discharges which are aligned in a periodic array. In the streamer context, the relevant regularisation on the interface is not provided by surface tension, but instead has been postulated to involve a mechanism equivalent to kinetic undercooling, which acts to penalise high velocities and prevent blow-up of the unregularised solution. Previous asymptotic results for the Hele-Shaw finger problem with kinetic undercooling suggest that for a given value of the kinetic undercooling parameter, there is a discrete set of possible finger shapes, each analytic at the nose and occupying a different fraction of the channel width. In the limit in which the kinetic undercooling parameter vanishes, the fraction for each family approaches 1/2, suggesting that this 'selection' of 1/2 by kinetic undercooling is qualitatively similar to the well-known analogue with surface tension. We treat the numerical problem of computing these Saffman-Taylor fingers with kinetic undercooling, which turns out to be more subtle than the analogue with surface tension, since kinetic undercooling permits finger shapes which are corner-free but not analytic. We provide numerical evidence for the selection mechanism by setting up a problem with both kinetic undercooling and surface tension, and numerically taking the limit that the surface tension vanishes.

description: The report examines the impact of artificial intelligence on vocational education and training in Europe. Based on a conceptual clarification, the societal and social aspects of this technology are examined using international literature. This includes various scenarios about future development as well as the effects on the commercial technical professions. A comprehensive analysis of future changes in qualifications and skills, especially with regard to the various professions, is undertaken. Chapter five looks at important subaspects of vocational education and training such as tutorial learning support, the creation of new learning environments such as »smart classrooms & factories«, as well as learning analytics and digital assessment. The empirical part of the study contains a summary evaluation of the more than 40 interviews carried out in the European countries Germany, Greece, Italy, Lithuania and UK. The first project approaches are presented in case studies, in which AI is used in corresponding projects. The results of the online survey conducted in Germany among vocational school teachers will then be presented. The summary underlines the complex effects of this new technology with regard to the further development of professional content and which methodological didactic measures in the form of a new kind of professional learning and work tasks are especially necessary.

description: Digital tools are essential in geosciences. ITC’s state-of-the-art Geospatial Computing Platform provides such tools for research and education purposes. Many of the provided tools are also useful for citizen science (CS) projects and ITC can significantly facilitate such activities through the platform. However, the threshold to start using them is currently high and any serious attempt to support CS requires a well-designed approach with training targeting citizen scientists. This includes primary and secondary school students, whose curricula pay special attention on digital technology and promote involvement to CS activities. This project focuses on this group and aims to find out how pre-university students and teachers can be supported to use a modern digital geoscience toolbox for CS projects. In cooperation with UT Pre‑U, a feasibility study will be performed to identify how the platform and available tools can be used for CS activities, including blitz campaigns. Potential use cases and expected impacts will be documented. Finally, a roadmap for developing well-written training material for the target audience will be prepared in consultation with teachers.
Non-contractible Periodic Orbits in Hamiltonian Dynamics on Closed Symplectic Manifolds

description: We study Hamiltonian diffeomorphisms of closed symplectic manifolds with non-contractible periodic orbits. In a variety of settings, we show that the presence of one non-contractible periodic orbit of a Hamiltonian diffeomorphism of a closed toroidally monotone or toroidally negative monotone symplectic manifold implies the existence of infinitely many non-contractible periodic orbits in a specific collection of free homotopy classes. The main new ingredient in the proofs of these results is a filtration of Floer homology by the so-called augmented action. This action is independent of capping, and, under favorable conditions, the augmented action filtration for toroidally (negative) monotone manifolds can play the same role as the ordinary action filtration for atoroidal manifolds.

Controlling entropic uncertainty bound through memory effects

description: One of the defining traits of quantum mechanics is the uncertainty principle which was originally expressed in terms of the standard deviation of two observables. Alternatively, it can be formulated using entropic measures, and can also be generalized by including a memory particle that is entangled with the particle to be measured. Here we consider a realistic scenario where the memory particle is an open system interacting with an external environment. Through the relation of conditional entropy to mutual information, we provide a link between memory effects and the rate of change of conditional entropy controlling the lower bound of the entropic uncertainty relation. Our treatment reveals that the memory effects stemming from the non-Markovian nature of quantum dynamical maps directly control the lower bound of the entropic uncertainty relation in a general way, independently of the specific type of interaction between the memory particle and its environment.

description: SuperSpec is a novel on-chip spectrometer we are developing for multi-object, moderate resolution (R = 100 - 500), large bandwidth (~1.65:1) submillimeter and millimeter survey spectroscopy of high-redshift galaxies. The spectrometer employs a filter bank architecture, and consists of a series of half-wave resonators formed by lithographically-patterned superconducting transmission lines. The signal power admitted by each resonator is detected by a lumped element titanium nitride (TiN) kinetic inductance detector (KID) operating at 100-200 MHz. We have tested a new prototype device that is more sensitive than previous devices, and easier to fabricate. We present a characterization of a representative R=282 channel at f = 236 GHz, including measurements of the spectrometer detection efficiency, the detector responsivity over a large range of optical loading, and the full system optical efficiency. We outline future improvements to the current system that we expect will enable construction of a photon-noise-limited R=100 filter bank, appropriate for a line intensity mapping experiment targeting the [CII] 158 micron transition during the Epoch of Reionization

description: In einer Zeit, in der schulische Herausforderungen zunehmen, erweist sich kooperatives Lernen als wirksames Mittel zu ihrer Bewältigung. Dabei ist es jedoch unerlässlich, dass Schüler*innen ihre Exekutiven Funktionen (EF) «im Griff haben». Diese sind zentral für das Lenken der Gedanken, Gefühle und Handlungen. Das Zusammenwirken zwischen den EF und kooperativem Lernen prägt den Lernprozess massgeblich. Basierend auf einer Literaturrecherche und einer qualitativen Inhaltsanalyse wird diese Wechselwirkung beleuchtet und aufgezeigt, wie EF durch kooperatives Lernen gefördert werden und umgekehrt. Gestützt auf den gewonnenen Erkenntnissen und mittels einer Befragung wurde ein Produkt entwickelt, das Lehrpersonen als praktische Planungshilfe dienen soll, um eine zielführende Berücksichtigung dieser beiden Themen bei der Unterrichtsvorbereitung zu gewährleisten.

description: For a graph $G$, the signless Laplacian Estrada index is defined as $SLEE(G)=\sum^{n}_{i=1}e^{q^{}_i}$,where $q_1, q_2, \dots, q_n$are the eigenvalues of the signless Laplacian matrix of $G$. In this paper, we first characterize the unicyclic graphs with the first two largest and smallest $SLEE$ and then determine the unique unicyclic graph with maximum $SLEE$ among the unicyclic graphs on $n$ vertices with given diameter.

description: Based on an improved isospin- and momentum-dependent interaction, we have studied the qualitative effect of isospin splitting of nucleon effective mass on the specific shear viscosity of neutron-rich nuclear matter from a relaxation time approach. It is seen that for $m_n^\star>m_p^\star$, the relaxation time of neutrons is smaller and the neutron flux between flow layers is weaker, leading to a smaller specific shear viscosity of neutron-rich matter compared to the case for $m_n^\star
