Homological reduction of constrained Poisson algebras
Creators: name: Stasheff, Jim
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1997

description: Reduction of a Hamiltonian system with symmetry and/or constraints has a long history. There are several reduction procedures, all of which agree in "nice" cases [1]. Some have a geometric emphasis - reducing a (symplectic) space of states [39], while others are algebraic- reducing a (Poisson) algebra of observables [43]. Some start with a momentum map whose components are constraint functions [15]; some start with a gauge (symmetry) algebra whose generators, regarded as vector fields, correspond via the symplectic structure to constraints [10]. The relation between symmetry and constraints is particularly tight in the case Dirac calls "first class". The present paper is concerned entirely with this first class case and deals with the reduction of a Poisson algebra via homological methods, although there is considerable motivation from topology, particularly via the models central to rational homotopy theory.

Subjects: Steganografie, Developer Framework

description: Diese Arbeit beschäftigt sich mit der steganografischen Bearbeitung von Bildern und der
 Verbreitung des Ergebnisses über öffentliche, unverschlüsselte Kanäle.
 Steganografie bezeichnet die Kunst, Informationen so in einem Medium unterzubringen,
 dass diese selbst für einen investigativen Beobachter schwer zu entdecken sind. Ziel ist, die
 Kommunikation an sich geheim zu halten, die Verschlüsselung einer bereits entdeckten
 Kommunikation steht nicht im Fokus.
 Die Anforderungen an steganografisch bearbeitete Bilder schließen schlechte Wahrnehm-
 barkeit der Bildveränderung und Resistenz gegen statistische Angriffe, aber auch gegen
 Kompression ein, die bei der Veröffentlichung auf einem Kanal stattfinden könnte.
 Diese Arbeit beschreibt das Vorgehen bei dem simultan bearbeiteten Projekt, in dessen
 Ergebnis die erfolgreiche Verbreitung von steganografisch versteckten Informationen in
 Bildern über öffentliche Kanäle möglich ist. Dabei werden verschiedene Konzepte der
 Steganografie vorgestellt und eine konfigurier- und erweiterbare Struktur implementiert,
 die die Verwendung unterschiedlicher steganografischer Methoden anbietet.
Connectedness principle for $3$-folds in characteristic $p>5$

description: A conjecture, known as the Shokurov-Kollár connectedness principle, predicts the following. Let $(X,B)$ be a pair, and let $f \colon X \rightarrow S$ be a contraction with $-(K_X + B)$ nef over $S$; then, for any point $s \in S$, the intersection $f^{-1} (s) \cap \mathrm{Nklt}(X,B)$ has at most two connected components, where $\mathrm{Nklt}(X,B)$ denotes the non-klt locus of $(X,B)$. This conjecture has been extensively studied in characteristic zero, and it has been recently settled in that context. In this work, we consider this conjecture in the setup of positive characteristic algebraic geometry. We prove this conjecture holds for threefolds in characteristic $p> 5$, and, under the same assumptions, we characterize the cases in which $\mathrm{Nklt}(X,B)$ fails to be connected.

description: In Business Process Management (BPM), process modelling has been solved in various ways. However, there are no commonly accepted modelling tools (languages). Some of them are criticized for their inability to capture both the lifecycle, informational and organizational models of processes. For some others, process modelling is generally done using a single graph; this does not facilitate modularity, maintenance and scalability. In addition, some of these languages are very general; hence, their application to specific domain processes (such as administrative processes) is very complex. In this paper, we present a new language and a new methodology, dedicated to administrative process modelling. This language is based on a variant of attributed grammars and is able to capture the lifecycle, informational and organizational models of such processes. Also, it proposes a simple graphical formalism allowing to model each process's execution scenario as an annotated tree (modularity). In the new language, a particular emphasis is put on modelling (using "views") the perceptions that actors have on processes and their data.
The impact of the faculty-student relationship on student course engagement
Creators: name: Zhang, Xing
Publisher: name: ETH Learning and Teaching Journal
Year: 2020

description: This study introduces the situation of the faculty-student relationship and students’ course engagement and analyzes the influence of the former on the latter. The research sample included 457 undergraduates, who come from Shanghai Jiao Tong University. The study found that almost all undergraduates can participate fully in class, but take part in fewer participation/interaction activities. The faculty-student relationship places the highest score on “Satisfaction” and the lowest score on “Conflict”. Conflict is a negative predictor of attitude engagement; the Support scale and the “Closeness” scale have a positive impact on student engagement, in contrast to the “Attitude” scale.

Variation of GIT and Variation of Lagrangian Skeletons II: Quasi-Symmetric Case

Year: 2020

subject: FOS: Mathematics

description: Consider $(\mathbb{C}^*)^k$ acting on $\mathbb{C}^N$ satisfying certain 'quasi-symmetric' condition which produces a class of toric Calabi-Yau GIT quotient stacks. Using subcategories of $Coh([\mathbb{C}^N / (\mathbb{C}^*)^k])$ generated by line bundles whose weights are inside certain zonotope called the 'magic window', Halpern-Leistner and Sam give a combinatorial construction of equivalences between derived categories of coherent sheaves for various GIT quotients. We apply the coherent-constructible correspondence for toric varieties to the magic windows and obtain a non-characteristic deformation of Lagrangian skeletons in $\mathbb{R}^{N-k}$ parameterized by $\mathbb{R}^k$, exhibiting derived equivalences between A-models of the various phases. Moreover, by translating the magic window zonotope in $\mathbb{R}^k$, we obtain a universal skeleton over $\mathbb{R}^k \times \mathbb{R}^k \setminus \mathcal{D}$ for some fattening of hyperplane arrangements $\mathcal{D}$, and we show that the the universal skeleton induces a local system of categories over $\mathbb{R}^k \times \mathbb{R}^k \setminus \mathcal{D}$. We also connect our results to the perverse schober structure identified by Špenko and Van den Bergh.

We unravel a monoclinic to triclinic phase transition at 58 K, and a paramagnetic to stripe antiferromagnetic (AFM) phase transition at 54 K, below which spins order 45$^\circ$ away from the stripe direction. Furthermore, we demonstrate this material is substantially structurally untwinned at ambient pressure with the formation of spin rotation walls (S-walls). Finally, in addition to the central-hole and corner-electron Fermi pockets usually appearing in Fe pnictide superconductors, angle-resolved photoemission (ARPES) measurements resolve a Fermiology where an extra electron pocket of mainly As chain character exists at the Brillouin zone edge.

Year: 2020

description: Future oriented pedagogy deals with changes in learning and adaptability to them. Awareness of a personal resource pool, the ability to recognize task-specific strengths and constructive learning are all important components here and can assist in training learners in the 21st century. Our premise is that people use their personal strengths to perform tasks, but they do so subconsciously. The purpose of this paper is to examine how raising awareness of strengths, expanding the personal resource pool and consciously selecting strengths for a specific task – “escape boxes” – can improve both learning itself and the learning experience. The study used Switzerland-themed “escape boxes” that suited the ICED 2020 convention, which was cancelled due to COVID-19. Our study shows that learning through “escape boxes” and awareness and selection of task-specific strengths improve learning and the learning experience.

description: We present the deepest optical photometry for any dwarf elliptical (dE) galaxy based on Hubble Space Telescope ACS observations of the Local Group dE galaxies NGC 147 and NGC 185. The resulting F606W and F814W color-magnitude diagrams are the first to reach below the main sequence turnoff in a dE galaxy, allowing us to determine full star formation histories in these systems. The ACS fields are located ~1.5 effective radii from the galaxy center to avoid photometric crowding. While our ACS pointings in both dEs show unambiguous evidence for old and intermediate age stars, the mean age in NGC 147 is ~ 4 Gyr younger as compared to NGC 185. In NGC 147, only 40% of stars were in place 12.5 Gyrs ago (z~5), with the bulk of the remaining stellar population forming between 5 to 7 Gyr. In contrast, 70% of stars were formed in NGC 185 field more than12.5 Gyr ago with the majority of the remaining population forming between 8 to 10 Gyr. Star formation ceased in both ACS fields at least 3 Gyr ago. Previous observations in the central regions of NGC 185 show evidence for star formation as recent as 100 Myr ago and a strong metallicity gradient with radius. We suggest that the orbit of NGC 185 has a larger pericenter as compared to NGC 147, allowing it to preserve radial gradients and maintain a small central reservoir of recycled gas. We interpret the inferred differences in star formation histories to imply an earlier infall time into the M31 environment for NGC 185 as compared to NGC 147.

description: Classification of polarimetric synthetic aperture radar (PolSAR) images is an active research area with a major role in environmental applications. The traditional Machine Learning (ML) methods proposed in this domain generally focus on utilizing highly discriminative features to improve the classification performance, but this task is complicated by the well-known "curse of dimensionality" phenomena. Other approaches based on deep Convolutional Neural Networks (CNNs) have certain limitations and drawbacks, such as high computational complexity, an unfeasibly large training set with ground-truth labels, and special hardware requirements. In this work, to address the limitations of traditional ML and deep CNN based methods, a novel and systematic classification framework is proposed for the classification of PolSAR images, based on a compact and adaptive implementation of CNNs using a sliding-window classification approach. The proposed approach has three advantages. First, there is no requirement for an extensive feature extraction process. Second, it is computationally efficient due to utilized compact configurations. In particular, the proposed compact and adaptive CNN model is designed to achieve the maximum classification accuracy with minimum training and computational complexity. This is of considerable importance considering the high costs involved in labelling in PolSAR classification. Finally, the proposed approach can perform classification using smaller window sizes than deep CNNs. Experimental evaluations have been performed over the most commonly-used four benchmark PolSAR images: AIRSAR L-Band and RADARSAT-2 C-Band data of San Francisco Bay and Flevoland areas. Accordingly, the best obtained overall accuracies range between 92.33 - 99.39% for these benchmark study sites.
Workshop: Experiential learning for future ready teaching

Year: 2020

description: Amongst the many proven truths emerging during 2020 is the certain uncertainty about the future. Before Covid-19, the rise of automation across all industries and disciplines saw an increased demand for skill sets in graduates that enabled emerging employees to traverse the unknown, preparing them to be competitive in a job market with an unseen landscape. The global pandemic has accelerated the interest in these skills, and educators need to ensure that attention remains on the development of these skills. This skill curriculum need not compete with discipline-specific skills education, but rather sit alongside it to compliment the development of soft skill competencies using teaching methodologies that can be adapted and curated according to even the most specific industry needs. For a future world (where 85% of jobs in 2030 do not yet exist), the need for cognitive flexibility, critical thinking, creativity, innovation and complex problem solving is expected to increase. Experiential learning systems allow the exploration of these skills, and the hands-on, minds- on nature of this type of learning ensures that students are ready for real-world application sooner. This workshop invites participants to engage in some of these teaching methodologies, and explores not only the activities, but the follow-up reflection work which embeds student learning into long term acquisition of knowledge.

description: The existence of multi-pulse solutions near orbit-flip bifurcations of a primary single-humped pulse is shown in reversible, conservative, singularly perturbed vector  elds. Similar to the nonsingular case, the sign of a geometric condition that involves the  first integral decides whether multi-pulses exist or not. The proof utilizes a combination of geometric singular perturbation theory and Lyapunov-Schmidt reduction through Lin's method. The motivation for considering orbit flips in singularly perturbed systems comes from the regularized short-pulse equation and the Ostrovsky equation, which both fi t into this framework and are shown here to support multi-pulses.

Approximation of Random Slow Manifolds and Settling of Inertial Particles Under Uncertainty

description: A method is provided for approximating random slow manifolds of a class of slow-fast stochastic dynamical systems. Thus approximate, low dimensional, reduced slow systems are obtained analytically in the case of sufficiently large time scale separation. To illustrate this dimension reduction procedure, the impact of random environmental fluctuations on the settling motion of inertial particles in a cellular flow field is examined. It is found that noise delays settling for some particles but enhances settling for others. A deterministic stable manifold is an agent to facilitate this phenomenon. Overall, noise appears to delay the settling in an averaged sense.

description: Katz and Sarnak conjectured a correspondence between the $n$-level density statistics of zeros from families of $L$-functions with eigenvalues from random matrix ensembles. In many cases the sums of smooth test functions, whose Fourier transforms are finitely supported, over scaled zeros in a family converge to an integral of the test function against a density $W_{n, G}$ depending on the symmetry $G$ of the family (unitary, symplectic or orthogonal). This integral bounds the average order of vanishing at the central point of the corresponding family of $L$-functions. We can obtain better estimates on this vanishing by finding better test functions to minimize the integral. We pursue this problem when $n=2$, minimizing \[ \frac{1}{Φ(0, 0)} \int_{{\mathbb R}^2} W_{2,G} (x, y) Φ(x, y) dx dy \] over test functions $Φ\colon {\mathbb R}^2 \to [0, \infty)$ with compactly supported Fourier transform. We study a restricted version of this optimization problem, imposing that our test functions take the form $ϕ(x) ψ(y)$ for some fixed admissible $ψ(y)$ and $\mathrm{supp}({\hat ϕ}) \subseteq [-1, 1]$. Extending results from the $1$-level case, namely the functional analytic arguments of Iwaniec, Luo and Sarnak and the differential equations method introduced by Freeman and Miller, we explicitly solve for the optimal $ϕ$ for appropriately chosen fixed test function $ψ$. The solution allows us to deduce strong estimates for the proportion of newforms of rank $0$ or $2$ in the case of $\mathrm{SO}(\mathrm{even})$, rank $1$ or $3$ in the case of $\mathrm{SO}(\mathrm{odd})$, and rank at most $2$ for $\mathrm{O}$, $\mathrm{Sp}$, and $\mathrm{U}$; our estimates are a significant strengthening of the best known estimates obtained with the $1$-level density. We conclude by discussing further improvements on estimates by the method of iteration.

description: Historically, the element of uncertainty in quantum mechanics has been expressed through mathematical identities called uncertainty relations, a great many of which continue to be discovered. These relations use diverse measures to quantify uncertainty (and joint uncertainty). In this paper we use operational information-theoretic principles to identify the common essence of all such measures, thereby defining measure-independent notions of uncertainty and joint uncertainty. We find that most existing entropic uncertainty relations use measures of joint uncertainty that yield themselves to a small class of operational interpretations. Our notion relaxes this restriction, revealing previously unexplored joint uncertainty measures. To illustrate the utility of our formalism, we derive an uncertainty relation based on one such new measure. We also use our formalism to gain insight into the conditions under which measure-independent uncertainty relations can be found.

We show that supersymmetric solutions are in one-to-one correspondence with solutions to a set of differential constraints on an SU(2) structure. As an application of our results we (i) show that this structure reduces at a conformal boundary to the five-dimensional rigid supersymmetric geometry previously studied by the authors, (ii) find a general expression for the holographic dual of the VEV of a BPS Wilson loop, matching an exact field theory computation, (iii) construct holographic duals to squashed Sasaki-Einstein backgrounds, again matching to a field theory computation, and (iv) find new analytic solutions.

description: We propose a new concept of secure list decoding, which is related to bit-string commitment. While the conventional list decoding requires that the list contains the transmitted message, secure list decoding requires the following additional security conditions to work as a modification of bit-string commitment. The first additional security condition is the receiver's uncertainty for the transmitted message, which is stronger than the impossibility of the correct decoding, even though the transmitted message is contained in the list. The other additional security condition is the impossibility for the sender to estimate another element of the decoded list except for the transmitted message. The first condition is evaluated by the equivocation rate. The asymptotic property is evaluated by three parameters, the rates of the message and list sizes, and the equivocation rate. We derive the capacity region of this problem. We show that the combination of hash function and secure list decoding yields the conventional bit-string commitment. Our results hold even when the input and output systems are general probability spaces including continuous systems. When the input system is a general probability space, we formulate the abilities of the honest sender and the dishonest sender in a different way.

(1) The definition of secure list decoding of this paper contains the equivocation rate while arXiv:1901.02590 does not consider it. (2) This paper shows that our secure list decoding can be applied to bit-string commitment while the paper arXiv:1901.02590 does not consider it

description: Microwave sheath-Voltage combination Plasma (MVP) is a high density plasma source and can be used as a suitable plasma processing device (e.g., ionized physical vapor deposition). In the present report, the temporal behavior of an argon MVP sustained along a direct-current biased Ti rod is investigated. Two plasma modes are observed, one is an "oxidized state" (OS) at the early time of the microwave plasma and the other is "ionized sputter state" (ISS) at the later times. Transition of the plasma from OS to ISS, results a prominent change in the visible color of the plasma, resulting from a significant increase in the plasma density, as measured by a Langmuir probe. In the OS, plasma is dominated by Ar ions and the density is order 10^11 cm^-3. In the ISS, metal ions from the Ti rod contribute significantly to the ion composition and higher density plasma (10^12 cm^-3) is produced. Nearly uniform high density plasma along the length of the Ti rod is produced at very low input microwave powers (around 30 W). Optical emission spectroscopy measurements confirm the presence of sputtered Ti ions and Ti neutrals in the ISS.

description: Higher education institutions increasingly acknowledge their responsibility to guide students, both in their career development and academic growth (Burke, Scurry, Blenkinsopp & Graley, 2017; National Academy of Engineering. 2018), so recognising the impact of (co-)curricular activities on professional competences is crucial (Kinoshita, Young & Knight. 2015). This research looks into the students’ perspective on the development of professional competences as a Peer Assisted Learning (PAL) tutor. In total, 27 tutors participated in the PAL programme of the Faculty of Engineering Technology (FET), KU Leuven (Belgium). The process included didactic and pedagogical training which prepared the tutors for their educational tasks. Via intermediate and final group discussions, hindrances and opportunities were discussed and tackled. Finally, an online individual questionnaire shed light on the competences indicated. Tutors and tutees indicated many benefits of PAL for their learning activities, such as fostering the ability to communicate clearly and cooperate better. To conclude, we need to keep giving students the possibility to develop their competences via different types of (co-)curricular activity to ensure student involvement and maintain high-quality education.

description: Interest has been growing in testing for nonlinearity or chaos in economic data, but much controversy has arisen about the available results. This paper explores the reasons for these empirical difficulties. We designed and ran a single-blind controlled competition among five highly regarded tests for nonlinearity or chaos with ten simulated data series. The data generating mechanisms include linear processes, chaotic recursions, and nonchaotic stochastic processes; and both large and small samples were included in the experiment. The data series were produced in a single blind manner by the competition manager and sent by e-mail, without identifying information, to the experiment participants. Each such participant is an acknowledged expert in one of the tests and has a possible vested interest in producing the best possible results with that one test. The results of this competition provide much surprising information about the power functions of some of the best regarded tests for nonlinearity or noisy chaos.

description: In this paper, we study consensus-based optimization (CBO), which is a multi-agent metaheuristic derivative-free optimization method that can globally minimize nonconvex nonsmooth functions and is amenable to theoretical analysis. Based on an experimentally supported intuition that, on average, CBO performs a gradient descent of the squared Euclidean distance to the global minimizer, we devise a novel technique for proving the convergence to the global minimizer in mean-field law for a rich class of objective functions. The result unveils internal mechanisms of CBO that are responsible for the success of the method. In particular, we prove that CBO performs a convexification of a large class of optimization problems as the number of optimizing agents goes to infinity. Furthermore, we improve prior analyses by requiring mild assumptions about the initialization of the method and by covering objectives that are merely locally Lipschitz continuous. As a core component of this analysis, we establish a quantitative nonasymptotic Laplace principle, which may be of independent interest. From the result of CBO convergence in mean-field law, it becomes apparent that the hardness of any global optimization problem is necessarily encoded in the rate of the mean-field approximation, for which we provide a novel probabilistic quantitative estimate. The combination of these results allows to obtain probabilistic global convergence guarantees of the numerical CBO method.

Forming future-ready graduates by focusing on the collective dimension of employability
Creators: name: Lungren-Resenterra, Mariangela
Publisher: name: ETH Learning and Teaching Journal
Year: 2020

description: Preparing future-ready graduates who fit readily into labour markets represents a significant issue for higher education institutions (HEIs) worldwide. Industrial stakeholders and HEIs claim that forming students ready for employment implies providing them with the necessary qualifications and personal skills essential for future work. This viewpoint has been challenged by recent research on employability conducted by Kahn and Lundgren-Resenterra. They argue that such interpretations label higher education merely as a personal commodity acquired and consumed for an individual economic reward, thus undermining possibilities to frame employability as developing collective interests. This paper reflects on reinforcing the collective dimension of learning strategies, thereby avoiding reduction of the value of learning to purely labour market needs. It aims to answer the following key research question: How can HEIs provide learning strategies designed to develop graduates’ collective interests towards work through collective reflexivity and corporate agency, whose emancipatory use-value is transferable to workplace collectives? The paper draws on critical realism, and more specifically on Archer’s work, to understand how collective reflexivity generates the emancipation of group members. Meanwhile, expansive learning is viewed as an alternative way of learning and knowledge construction as it relies on sharing concerns and interests with peers, thereby triggering change. Expansive learning cycles will be implemented in a Bachelor’s-level HR Management course of a Swiss School of Business Administration to evaluate by term’s end how students perceive expansion learning as a means of developing their reflexivity and corporate agency, thereby questioning existing current assumptions about employability based on the skillset discourse. Such measures should help HEIs reach beyond the skills agenda discourse dictated by labour markets and provide graduates with learning opportunities that emancipate them to be agents who develop their own narratives for their future work paths, thereby ennobling the role of HEIs.
