title: The weight of history: change and continuity in German foreign policy towards the Israeli-Palestinian conflict
Creators: name: Kreft, Anne-Kathrin
Publisher: name: Western Washington University
Year: 2010

description:
This study tests whether the consensus on German foreign policy continuity after unification is applicable to foreign policy towards the Israeli-Palestinian conflict, where the involvement is complicated by historical legacies resulting from the Holocaust, and includes an evaluation of realist and constructivist theories. An interpretative case study with comparative insights from EU, UK and French foreign policy considers three cases in the pre- and two in the postunification period: the 1967 War, the 1982 Israel-Lebanon War and the 1987 Intifada; and the Red-Green Coalition period from 2000-2005 and the Grand Coalition period from 2005-2009 respectively. The hypothesis of foreign policy continuity caused primarily by an elite level norm of philo-Zionism is confirmed, although a constructivist reading needs to also acknowledge rational liberal norm compliance. European integration and national interests are further determinants of German foreign policy towards the conflict, whereas transatlantic relations and U.S. involvement have merely an enabling or obstructing impact on the success of German (and European) policy. While the findings support constructivism and illustrate the salience of norms in German foreign policy making, they also demonstrate the limitations of the civilian power model, which is at the core of the constructivist continuity thesis.

description: For quasifields, the concept of parastrophy is slightly weaker than isotopy. Parastrophic quasifields yield isomorphic translation planes but not conversely. We investigate the right multiplication groups of finite quasifields. We classify all quasifields having an exceptional finite transitive linear group as right multiplication group. The classification is up to parastrophy, which turns out to be the same as up to the isomorphism of the corresponding translation planes.
title: Large scale neural dynamics of rhythmic sensorimotor coordination and stability
Creators: name: Borrell, Joseph William
Publisher: name: Western Washington University
Year: 2010

description:
Coordination Dynamics posits that the stability of coordinated patterns of movement may be a key variable for organizing neural activity underlying coordinated action. In support, recent findings suggest that premotor areas play an important role in maintaining pattern stability. The present EEG study investigates how changes in neural activation (assessed via event-related power) are affected both by rate and stability of coordination. Nineteen participants coordinated finger taps with an auditory metronome in either a synchronized or syncopated pattern presented at five different rates (1.00, 1.25, 1.50, 1.75, and 2.00 Hz). Premotor areas demonstrated increases in event-related synchronization (neural deactivation) within the alpha band following slow, synchronized movements. Stepwise increases in rate led to greater desynchronization (neural activation) throughout the entire duration of the movement cycle. During syncopation medial premotor regions remained desynchronized during movement. Moreover, medial premotor was more involved during synchronization with subsequent increases in movement rate. Counter to previous findings, medial premotor did not modulate changes in coordination stability. We suggested that medial premotor regions are involved in processes related to the coincidence of the finger tap and auditory tone. These findings support premotor cortex's role in motor inhibition, timing, and execution.

description: The Turing machine models an old-fashioned computer, that does not interact with the user or with other computers, and only does batch processing. Therefore, we came up with a Reactive Turing Machine that does not have these shortcomings. In the Reactive Turing Machine, transitions have labels to give a notion of interactivity. In the resulting process graph, we use bisimilarity instead of language equivalence. Subsequently, we considered other classical theorems and notions from automata theory and formal languages theory. In this paper, we consider the classical theorem of the correspondence between pushdown automata and context-free grammars. By changing the process operator of sequential composition to a sequencing operator with intermediate acceptance, we get a better correspondence in our setting. We find that the missing ingredient to recover the full correspondence is the addition of a notion of state awareness.
Challenges to the Bohr Wave Particle Complementarity Principle

description: Contrary to the Bohr complementarity principle, in 1995 Rabinowitz proposed that by using entangled particles from the source it would be possible to determine which slit a particle goes through while still preserving the interference pattern in the Young two slit experiment. In 2000, Kim et al used spontaneous parametric down conversion to prepare entangled photons as their source, and almost achieved this. In 2012, Menzel et al. experimentally succeeded in doing this. When the source emits entangled particle pairs, the traversed slit is inferred from measurement of the entangled particle location by using triangulation. The violation of complementarity breaches the prevailing probabilistic interpretation of quantum mechanics, and benefits the Bohm pilot wave theory.

Year: 2020

description: В современной школе умение анализировать художественный текст и воспринимать его эстетически оказывается практически не нужно. Литература воспринимается в первую очередь как дидактическая публицистика, поучающая школьника, как нужно жить. С этим связано и то, что навыки разговора о литературе у школьников сводятся к умению оперировать определенными формулами, клише, за которыми не стоит реального смысла. Понимание того, как устроен текст, подменяется поверхностными суждениями об этических посылах автора. Незаинтересованность школьников в анализе художественного текста видится связанной с нацеленностью учащихся на конкретный результат, не требующий глубоких знаний по предмету. Представляется, что в подобной ситуации оказываются не только школьники, но и учителя. Описываемые тенденции можно свидетельствовать о том, что в русской культуре все отчетливей проявляются черты культуры «готового слова».
RKKY interaction induced by two-dimensional hole gases

description: We analytically compute the RKKY range function as induced by two-dimensional (2D) hole gases. The bulk valence-band includes heavy-hole (HH) and light-hole (LH) states and their dynamics is described by the Luttinger Hamiltonian which we adopt as our framework. We show that even for situations where only the lowest HH-like subband is occupied the resulting form of the RKKY function can be very different as compared to the one of a 2D electron gas. The associated spin susceptibility tensor has entries along the quantum-well directions and perpendicular to it. Our formluae for the spin susceptibility tensor reveal the crucial influence of HH-LH mixing which gives rise to large anisotropies both among the in-plane components as well as among the in-plane components and the component perpendicular to the quantum-well.

description: Whittle index is a generalization of Gittins index that provides very efficient allocation rules for restless multi-armed bandits. In this work, we develop an algorithm to test the indexability and compute the Whittle indices of any finite-state restless bandit arm. This algorithm works in the discounted and non-discounted cases, and can compute Gittins index. Our algorithm builds on three tools: (1) a careful characterization of Whittle index that allows one to compute recursively the kth smallest index from the $(k - 1)$th smallest, and to test indexability, (2) the use of the Sherman-Morrison formula to make this recursive computation efficient, and (3) a sporadic use of the fastest matrix inversion and multiplication methods to obtain a subcubic complexity. We show that an efficient use of the Sherman-Morrison formula leads to an algorithm that computes Whittle index in $(2/3)n^3 + o(n^3)$ arithmetic operations, where $n$ is the number of states of the arm. The careful use of fast matrix multiplication leads to the first subcubic algorithm to compute Whittle or Gittins index: By using the current fastest matrix multiplication, the theoretical complexity of our algorithm is O(n^2.5286 ). We also develop an efficient implementation of our algorithm that can compute indices of Markov chains with several thousands of states in less than a few seconds.

Parametric study of efficiency measures for home energy conservation in Las Vegas, Nevada

description: Pulte Homes, a production home builder and community developer partnering with the U.S. Department of Energy's Building America program, has collaborated with the Center for Energy Research at the University of Nevada, Las Vegas and NV Energy, the local electric utility, on an energy conservation project in the Las Vegas Valley.

This study entails four model homes at a new development in the Summerlin community of Las Vegas, Nevada, named Villa Trieste. The home models, ranging in floor plan area from 1,487 to 1,777 square feet, have been constructed under the Environments for Living program and are LEED (Leadership in Energy and Environmental Design) platinum certified. According to the Home Energy Rating System (HERS) Index, all four models are over 50% more efficient than homes of equal size built with standard construction methods.

The study focuses on the cost benefit of including specific energy efficient upgrades in future homes built at the development. Though all proposed upgrades offer reductions in energy use, most offer little improvement relative to their additional installation costs. High-efficiency windows and heat recovery ventilators have been deemed appropriate upgrades for future homes. All homes at the development are to be equipped with photovoltaic arrays; increasing the size of the arrays will reduce net energy consumption in a cost-effective manner.

description: Based on the tensor network state representation, we develop a nonlinear dynamic theory coined as network contractor dynamics (NCD) to explore the thermodynamic properties of two-dimensional quantum lattice models. By invoking the rank-$1$ decomposition in the multi-linear algebra, the NCD scheme makes the contraction of the tensor network of the partition function be realized through a contraction of a local tensor cluster with vectors on its boundary. An imaginary-time-sweep algorithm for implementation of the NCD method is proposed for practical numerical simulations. We benchmark the NCD scheme on the square Ising model, which shows a great accuracy. Besides, the results on the spin-1/2 Heisenberg antiferromagnet on honeycomb lattice are disclosed in good agreement with the quantum Monte Carlo calculations. The quasi-entanglement entropy $S$, Lyapunov exponent $I^{lya}$ and loop character $I^{loop}$ are introduced within the dynamic scheme, which are found to display the ``nonlocality" near the critical point, and can be applied to determine the thermodynamic phase transitions of both classical and quantum systems.

description: We compute the total cross section for the production of a light CP even Higgs boson within the framework of supersymmetric QCD up to next-to-next-to-leading order. Technical subtleties in connection to the evaluation of three-loop Feynman integrals with many mass scales are discussed in detail and explicit results for the counterterms of the evanescent couplings are provided. The new results are applied to several phenomenological scenarios which are in accordance with the recent discovery at the LHC. In a large part of the still allowed parameter space the $K$ factor of the supersymmetric theory is close to the one of the Standard Model. However, for the case where one of the top squarks is light, a deviation of more than 5% in the next-to-next-to-leading order prediction of the cross section can be observed where at the same time the predicted Higgs boson mass has a value of about 125 GeV.

From feminism

Publisher: name: University of Nevada, Las Vegas

description: From Feminism means to emphasize a world-view rather than an a-priori eye towards women; the manuscript does occasionally strike a generic feminist-didactic mode, but for the most part its concerns are with humanity/ecology and gender goes un-marked or people are altogether absent. The world is various, and in terms of form, the poems in this book are rangy: sonnets, prose poems, serial fragments, free verse tercets, measured and rhymed tercets, couplets, over-the-top monuments to generation by rhyme. Unconventional use of white-space occurs fairly frequently. My thought is that having breaks in articulation in two places, not just the end of lines, may create potential for more sense, for a more various way to breathe. Many of these breath-oriented poems do end-up having a visual component, and I'm interested in the way prosodies geared towards the eye needn't be seen as adversarial to ones oriented around the ear and utterance, either song or speech or a medley.

description: Identifying phase transitions and classifying phases of matter is central to understanding the properties and behavior of a broad range of material systems. In recent years, machine-learning (ML) techniques have been successfully applied to perform such tasks in a data-driven manner. However, the success of this approach notwithstanding, we still lack a clear understanding of ML methods for detecting phase transitions, particularly of those that utilize neural networks (NNs). In this work, we derive analytical expressions for the optimal output of three widely used NN-based methods for detecting phase transitions. These optimal predictions correspond to the results obtained in the limit of high model capacity. Therefore, in practice they can, for example, be recovered using sufficiently large, well-trained NNs. The inner workings of the considered methods are revealed through the explicit dependence of the optimal output on the input data. By evaluating the analytical expressions, we can identify phase transitions directly from experimentally accessible data without training NNs, which makes this procedure favorable in terms of computation time. Our theoretical results are supported by extensive numerical simulations covering, e.g., topological, quantum, and many-body localization phase transitions. We expect similar analyses to provide a deeper understanding of other classification tasks in condensed matter physics.

We show that there exists a large family of such relations; the problem is in finding their algebraic-topologically meaningful parameterization. We solve this problem in part, providing two nicely parameterized subfamilies of such relations. For the second of them, we further investigate the nature of some of its parameters: they turn out to correspond to an exotic analogue of middle homologies. In passing, we also provide the 2-4 Pachner move relation for this second case.

description: We study countably infinite Markov decision processes (MDPs) with real-valued transition rewards. Every infinite run induces the following sequences of payoffs: 1. Point payoff (the sequence of directly seen transition rewards), 2. Mean payoff (the sequence of the sums of all rewards so far, divided by the number of steps), and 3. Total payoff (the sequence of the sums of all rewards so far). For each payoff type, the objective is to maximize the probability that the $\liminf$ is non-negative. We establish the complete picture of the strategy complexity of these objectives, i.e., how much memory is necessary and sufficient for $\varepsilon$-optimal (resp. optimal) strategies. Some cases can be won with memoryless deterministic strategies, while others require a step counter, a reward counter, or both.

description: Quantum error correction offers a promising path for performing quantum computations with low errors. Although a fully fault-tolerant execution of a quantum algorithm remains unrealized, recent experimental developments, along with improvements in control electronics, are enabling increasingly advanced demonstrations of the necessary operations for applying quantum error correction. Here, we perform quantum error correction on superconducting qubits connected in a heavy-hexagon lattice. The full processor can encode a logical qubit with distance three and perform several rounds of fault-tolerant syndrome measurements that allow the correction of any single fault in the circuitry. Furthermore, by using dynamic circuits and classical computation as part of our syndrome extraction protocols, we can exploit real-time feedback to reduce the impact of energy relaxation error in the syndrome and flag qubits. We show that the logical error varies depending on the use of a perfect matching decoder compared to a maximum likelihood decoder. We observe a logical error per syndrome measurement round as low as $\sim0.04$ for the matching decoder and as low as $\sim0.03$ for the maximum likelihood decoder. Our results suggest that more significant improvements to decoders are likely on the horizon as quantum hardware has reached a new stage of development towards fully fault-tolerant operations.

We treat the inverse Faraday effect (IFE) theoretically in terms of the spin-selective optical Stark effect for linearly or circularly polarized light. In the dilute magnetic semiconductors (Ga,Mn)As, strong laser pulses below the band gap induce effective magnetic fields of several teslas in a direction which depends on the magnetization and light wave vectors. Our theory demonstrates that the polarized light catalyzes the angular momentum transfer between lattice and the magnetization.

description: A mixed graph is a set of vertices together with an edge set and an arc set. An $(m,n)$-mixed graph $G$ is a mixed graph whose edges are each assigned one of $m$ colours, and whose arcs are each assigned one of $n$ colours. A \emph{switch} at a vertex $v$ of $G$ permutes the edge colours, the arc colours, and the arc directions of edges and arcs incident with $v$. The group of all allowed switches is $Γ$. Let $k \geq 1$ be a fixed integer and $Γ$ a fixed permutation group. We consider the problem that takes as input an $(m,n)$-mixed graph $G$ and asks if there a sequence of switches at vertices of $G$ with respect to $Γ$ so that the resulting $(m,n)$-mixed graph admits a homomorphism to an $(m,n)$-mixed graph on $k$ vertices. Our main result establishes this problem can be solved in polynomial time for $k \leq 2$, and is NP-hard for $k \geq 3$. This provides a step towards a general dichotomy theorem for the $Γ$-switchable homomorphism decision problem.

description: The problem of identifying a probabilistic context free grammar has two aspects: the first is determining the grammar's topology (the rules of the grammar) and the second is estimating probabilistic weights for each rule. Given the hardness results for learning context-free grammars in general, and probabilistic grammars in particular, most of the literature has concentrated on the second problem. In this work we address the first problem. We restrict attention to structurally unambiguous weighted context-free grammars (SUWCFG) and provide a query learning algorithm for \structurally unambiguous probabilistic context-free grammars (SUPCFG). We show that SUWCFG can be represented using \emph{co-linear multiplicity tree automata} (CMTA), and provide a polynomial learning algorithm that learns CMTAs. We show that the learned CMTA can be converted into a probabilistic grammar, thus providing a complete algorithm for learning a structurally unambiguous probabilistic context free grammar (both the grammar topology and the probabilistic weights) using structured membership queries and structured equivalence queries. A summarized version of this work was published at AAAI 21.

Defect states and excitations in a Mott insulator with orbital degrees of freedom: Mott-Hubbard gap versus optical and transport gaps in doped systems

description: We address the role played by charged defects in doped Mott insulators with active orbital degrees of freedom. It is observed that defects feature a rather complex and rich physics, which is well captured by a degenerate Hubbard model extended by terms that describe crystal-field splittings and orbital-lattice coupling, as well as by terms generated by defects such as the Coulomb potential terms that act both on doped holes and on electrons within occupied orbitals at undoped sites. We show that the multiplet structure of the excited states generated in such systems by strong electron interactions is well described within the unrestricted Hartree-Fock approximation, once the symmetry breaking caused by the onset of magnetic and orbital order is taken into account. Furthermore, we uncover new spectral features that arise within the Mott-Hubbard gap and in the multiplet spectrum at high energies due to the presence of defect states and strong correlations. These features reflect the action on electrons/holes of the generalized defect potential that affects charge and orbital degrees of freedom, and indirectly also spin ones. The present study elucidates the mechanism behind the Coulomb gap appearing in the band of defect states and investigates the dependence on the electron-electron interactions and the screening by the orbital polarization field. As an illustrative example of our general approach, we present explicit calculations for the model describing three t_2g orbital flavors in the perovskite vanadates doped by divalent Sr or Ca ions, such as in La_(1-x)Sr_xVO_3 and Y_(1-x)Ca_xVO_3 systems. We analyze the orbital densities at vanadium ions in the vicinity of defects, and the excited defect states which determine the optical and transport gaps in doped systems.

description: Neural networks have been successfully employed in various domains such as classification, regression and clustering, etc. Generally, the back propagation (BP) based iterative approaches are used to train the neural networks, however, it results in the issues of local minima, sensitivity to learning rate and slow convergence. To overcome these issues, randomization based neural networks such as random vector functional link (RVFL) network have been proposed. RVFL model has several characteristics such as fast training speed, direct links, simple architecture, and universal approximation capability, that make it a viable randomized neural network. This article presents the first comprehensive review of the evolution of RVFL model, which can serve as the extensive summary for the beginners as well as practitioners. We discuss the shallow RVFLs, ensemble RVFLs, deep RVFLs and ensemble deep RVFL models. The variations, improvements and applications of RVFL models are discussed in detail. Moreover, we discuss the different hyperparameter optimization techniques followed in the literature to improve the generalization performance of the RVFL model. Finally, we give potential future research directions/opportunities that can inspire the researchers to improve the RVFL's architecture and learning algorithm further.

title: Verrat in den eigenen Reihen? Hernán Valdés’ literarische Produktion als eine (unmögliche) differenzierte Kritik an der chilenischen Linken im Kalten Krieg

description: Seit Oktober 2019 gehen die Menschen in Chile wieder auf die Straße, um gegen die aktuelle politische und wirtschaftliche Lage zu demonstrieren. Es sind die größten Demonstrationen seit dem Ende der chilenischen Diktatur (1973–1990). Die Demonstrationen sind auch eine der Nachwirkungen der Diktatur, die tiefe Spuren in der ideologisch und ökonomisch gespaltenen Gesellschaft hinterlassen hat.
Der chilenische Autor Hernán Valdés (*1934) wurde zu Beginn der Diktatur gefangen genommen und gefoltert: Diese Erfahrung schrieb er in seinem Testimonialtext Tejas Verdes (1974) nieder und wurde quasi über Nacht weltberühmt, sein Text zum Beweisstück für die grausamen Verbrechen des chilenischen Militärs. Der nachfolgende Roman A partir del fin (1981) behandelt autofiktional die chilenische Gesellschaft vor und nach dem Putsch, kritisiert aber auch den demokratisch gewählten Präsidenten Salvador Allende und sein Regierungsbündnis Unidad Popular (1970–1973).
In dem vorliegenden Band werden diese Veröffentlichungen Valdés' im Wechselspiel von literarischer und empirischer Welt analysiert und miteinander in Beziehung gesetzt. Im Rahmen des Aufarbeitungsprozesses widmet sich diese Forschung der Rezeptionsgeschichte von Tejas Verdes und A partir del fin sowie ihren gesellschaftlichen Implikationen. Der frühere Text machte den Autoren in der Opposition zu Pinochet berühmt, der zweite dagegen, der eine nuancierte Kritik am eigenen politischen Lager darstellt, erschwert weiterhin die Wahrnehmung und Diskussion des Romans in einer ideologisch tief gespaltenen Gesellschaft. In dieser Studie wird der Zusammenhang von Literatur, Rezeptionsgeschichte und Kanonisierung exemplarisch untersucht sowie die Verbindung von Literatur und gesellschaftlichen Aufarbeitungsprozessen dargestellt.
Entanglement entropy, single-particle occupation probabilities, and short-range correlations

description: For quantum many-body systems with short-range correlations (SRCs), the intimate relationship between their magnitude, the behavior of the single-particle occupation probabilities at momenta larger than the Fermi momentum, and the entanglement entropy is a new qualitative aspect not studied and exploited yet. A large body of recent condensed matter studies indicate that the time evolution of the entanglement entropy describes the non-equilibrium dynamics of isolated and strongly interacting many-body systems, in a manner similar to the Boltzmann entropy, which is strictly defined for dilute and weakly interacting many-body systems. Both theoretical and experimental studies in nuclei and cold atomic gases have shown that the fermion momentum distribution has a generic behavior $n(k)=C/k^4$ at momenta larger than the Fermi momentum, due to the presence of SRCs, with approximately 20\% of the particles having momenta larger than the Fermi momentum. The presence of the long momentum tails in the presence of SRCs changes the textbook relation between the single-particle kinetic energy and occupation probabilities, $n_\text{mf}(k) = {1}/\{ 1+\expβ[ε(k)-μ]\}$ for momenta very different form the Fermi momentum, particularly for dynamics processes. SRCs induced high-momentum tails of the single-particle occupation probabilities increase the entanglement entropy of fermionic systems, which in its turn affects the dynamics of many nuclear reactions, such as heavy-ion collisions and nuclear fission.

Self-interacting Dark Radiation

description: We consider a simple class of models where dark radiation has self-interactions and therefore does not free stream. Such dark radiation has no anisotropic stress (or viscosity), leaving a distinct signature on the CMB angular power spectrum. Specifically we study a possibility that hidden gauge bosons and/or chiral fermions account for the excess of the effective number of neutrino species. They have gauge interactions and remain light due to the unbroken hidden gauge symmetry, leading to ΔN_{\rm eff} \simeq 0.29 in some case.

Dieser Artikel befasst sich mit den vielfältigen Herausforderungen der Produktionsoptimierung und untersucht die komplexe Landschaft, die durch technologische Fortschritte, Nachhaltigkeitsziele und Arbeitskräftedynamik geprägt ist. Im Kern dreht sich die Diskussion um die Einführung und Bedeutung der S = A ⊕ B-Formel – ein bahnbrechender mathematischer Ansatz, der die Einschränkungen herkömmlicher Summationsmethoden beim Umgang mit vielfältigen und dynamischen Datensätzen beseitigen soll. Die Formel dient als Eckpfeiler im Kontext der Produktionsplanung und bietet einen differenzierten und anpassungsfähigen Ansatz für die Summierung, der mit den Zielen der realen Welt übereinstimmt. Der Artikel betont die Rolle mathematischer Formeln bei der Optimierung von Fertigungsprozessen, der Personalzuteilung und der Erreichung von Produktionszielen. Praktische Überlegungen wie die Integration von Einschränkungen und die Bedeutung genauer Daten werden hervorgehoben und geben Einblicke in die Anwendung mathematischer Modelle in realen Produktionsszenarien. Die Untersuchung numerischer Lösungen und die Bewertung einer optimierten Arbeitskräftezuteilung unterstreichen das Engagement des Artikels, mathematische Präzision mit betrieblicher Machbarkeit und ethischen Überlegungen bei der Suche nach effizienten und gerechten Produktionssystemen zu verbinden.
title: Help-to-buy Scheme is Detached From How we Really Live

description: The government’s help-tobuy scheme, announced in the budget, was rightfully criticised by many people. Various ministers seemed a little surprised, if not a bit tetchy, that fewpeople had rowed in behind their latest genius wheeze. In research carried out by Davy stockbrokers and the property website myhome.ie, even firsttime buyers did not expect a helpto- buy scheme (people are not too easily schmoozed these days). Two other things flew under the radar when the proposal was announced. First, the silence from retail banks was deafening, which was strange given the allegedly positive response from the Central Bank. It nowlooks as though the bank was not as “on board” with the plan as ministers made out. (The government’s own Housing Agency merely “noted” the scheme in its budget response.)
