Salience, Inference and Plural Anaphora
Creators: name: Hardt, Daniel
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In this paper, I argue that the DRT Construction Rules for plural antecedents are redundant, because they are subsumed by an inference mechanism that must be made generally available for anaphora resolution. While Kamp and Reyle originally argued against a general inference mechanism for plural anaphora, I argue that the facts of compset anaphora require inference. Furthermore, I observe that compset anaphora is blocked by refset anaphora. I consider an alternative DRT account, in which inference coexists with Construction Rules. I argue that the Construction Rules are not necessary to capture the blocking generalization; rather, I argue that refset descriptions are semantically primed, thus deriving the blocking generalization in terms of general inference, together with an independently required mechanism of semantic priming. I argue that this alternative is to be preferred on grounds of theoretical parsimony. Furthermore, I present an argument that the general inference account correctly captures the fact that plural descriptions can be interpreted at the position of the plural pronoun, while the DRT account incorrectly requires that they be interpreted at the position of the antecedent.

description: We propose a matrix-free solver for the numerical solution of the cardiac electrophysiology model consisting of the monodomain nonlinear reaction-diffusion equation coupled with a system of ordinary differential equations for the ionic species. Our numerical approximation is based on the high-order Spectral Element Method (SEM) to achieve accurate numerical discretization while employing a much smaller number of Degrees of Freedom than first-order Finite Elements. We combine vectorization with sum-factorization, thus allowing for a very efficient use of high-order polynomials in a high performance computing framework. We validate the effectiveness of our matrix-free solver in a variety of applications and perform different electrophysiological simulations ranging from a simple slab of cardiac tissue to a realistic four-chamber heart geometry. We compare SEM to SEM with Numerical Integration (SEM-NI), showing that they provide comparable results in terms of accuracy and efficiency. In both cases, increasing the local polynomial degree $p$ leads to better numerical results and smaller computational times than reducing the mesh size $h$. We also implement a matrix-free Geometric Multigrid preconditioner that results in a comparable number of linear solver iterations with respect to a state-of-the-art matrix-based Algebraic Multigrid preconditioner. As a matter of fact, the matrix-free solver proposed here yields up to 45$\times$ speed-up with respect to a conventional matrix-based solver.

description: Hyperspectral images (HSI) classification is a high technical remote sensing software. The purpose is to reproduce a thematic map . The HSI contains more than a hundred hyperspectral measures, as bands (or simply images), of the concerned region. They are taken at neighbors frequencies. Unfortunately, some bands are redundant features, others are noisily measured, and the high dimensionality of features made classification accuracy poor. The problematic is how to find the good bands to classify the regions items. Some methods use Mutual Information (MI) and thresholding, to select relevant images, without processing redundancy. Others control and avoid redundancy. But they process the dimensionality reduction, some times as selection, other times as wrapper methods without any relationship . Here , we introduce a survey on all scheme used, and after critics and improvement, we synthesize a dashboard, that helps user to analyze an hypothesize features selection and extraction softwares.

description: This article presents a method of emotion analysis for German drama from the 17th to the 19th century that significantly goes beyond previous research approaches in computational literary studies. It is based on annotations of 17 dramatic texts resulting in 11,939 annotations which were used as training material to fine-tune a German language BERT model that achieves an average accuracy of 73% for the single-label emotion classification of fourteen emotion types in cross-validation. We apply the emotion classification on a corpus of 141 comedies and 92 tragedies to compare these genres. For tragedies, the mean proportion percentages of ‘suffering’ and ‘abhorrence’ are higher than for comedies. Inversely, mean percentages of ‘anger’ and ‘joy’ are higher for comedies than for tragedies. A new finding is the surprisingly high proportion of ‘anger’ in comedies. Emotion distribution of the last scenes in dramatic texts also proves the quality of the classified data in terms of literary studies. In addition, the emotion distribution for several subgenres of comedy is investigated including non-canonical works of wide circulation which reached the recipients directly through the depicted emotions in the Kasperl Plays. Comedies from 1740 to 1770 are characterized by a pairing of higher amounts of ‘friendship’ and ‘love’. Satirical comedies from the same period stand out due to high rates of ‘anger’ as well as ‘suffering’. The very successful Kasperl plays turn out to be characterized by a comparatively large percentage of ‘schadenfreude’ and ‘joy’.

description: Modern advances in particle physics depend strongly on the usage of reliable computer programs. In this context two issues become important: The usage of powerful algorithms to handle the amount of evaluated data properly, and a software architecture capable to overcome the problems of maintainability and extendability. We present our approach to such a computer program, called tapir. This tool assists computations in perturbative quantum field theory in many ways. Such calculations often involve the evaluation of a large amount of Feynman diagrams with multiple loops. tapir helps in reducing the number of diagrams, and the resulting integrals thereof, by identifying and minimizing their topological structure. We will focus on a three-loop calculation which is needed for the next-to-next-to leading order predictions of neutral $B$-meson systems. We show how tapir can be utilized for this kind of calculation.

description: Remote sensing is a higher technology to produce knowledge for data mining applications. In principle hyperspectral images (HSIs) is a remote sensing tool that provides precise classification of regions. The HSI contains more than a hundred of images of the ground truth (GT) map. Some images are carrying relevant information, but others describe redundant information, or they are affected by atmospheric noise. The aim is to reduce dimensionality of HSI. Many studies use mutual information (MI) or normalised forms of MI to select appropriate bands. In this paper we design an algorithm based also on MI, and we combine MI with steepest ascent algorithm, to improve a symmetric uncertainty coefficient-based strategy to select relevant bands for classification of HSI. This algorithm is a feature selection tool and a wrapper strategy. We perform our study on HSI AVIRIS 92AV3C. This is an artificial intelligent system to control redundancy; we had to clear the difference of the result's algorithm and the human decision, and this can be viewed as case study which human decision is perhaps different to an intelligent algorithm.

description: Wikipedia is one of the most visited websites in the world and is also a frequent subject of scientific research. However, the analytical possibilities of Wikipedia information have not yet been analyzed considering at the same time both a large volume of pages and attributes. The main objective of this work is to offer a methodological framework and an open knowledge graph for the informetric large-scale study of Wikipedia. Features of Wikipedia pages are compared with those of scientific publications to highlight the (di)similarities between the two types of documents. Based on this comparison, different analytical possibilities that Wikipedia and its various data sources offer are explored, ultimately offering a set of metrics meant to study Wikipedia from different analytical dimensions. In parallel, a complete dedicated dataset of the English Wikipedia was built (and shared) following a relational model. Finally, a descriptive case study is carried out on the English Wikipedia dataset to illustrate the analytical potential of the knowledge graph and its metrics.

description: With the rapid development of quantum computers, several applications are being proposed for them. Quantum simulations, simulation of chemical reactions, solution of optimization problems and quantum neural networks (QNNs) are some examples. However, problems such as noise, limited number of qubits and circuit depth, and gradient vanishing must be resolved before we can use them to their full potential. In the field of quantum machine learning, several models have been proposed. In general, in order to train these different models, we use the gradient of a cost function with respect to the model parameters. In order to obtain this gradient, we must compute the derivative of this function with respect to the model parameters. One of the most used methods in the literature to perform this task is the parameter-shift rule method. This method consists of evaluating the cost function twice for each parameter of the QNN. A problem with this method is that the number of evaluations grows linearly with the number of parameters. In this work we study an alternative method, called Evolution Strategies (ES), which are a family of black box optimization algorithms which iteratively update the parameters using a search gradient. An advantage of the ES method is that in using it one can control the number of times the cost function will be evaluated. We apply the ES method to the binary classification task, showing that this method is a viable alternative for training QNNs. However, we observe that its performance will be strongly dependent on the hyperparameters used. Furthermore, we also observe that this method, alike the parameter shift rule method, suffers from the problem of gradient vanishing.
Asymptotic properties of extremal Kähler metrics of Poincaré type

description: Consider a compact Kähler manifold X with a simple normal crossing divisor D, and define Poincaré type metrics on X\D as Kähler metrics on X\D with cusp singularities along D. We prove that the existence of a constant scalar curvature (resp. an extremal) Poincaré type Kähler metric on X\D implies the existence of a constant scalar curvature (resp. an extremal) Kähler metric, possibly of Poincaré type, on every component of D. We also show that when the divisor is smooth, the constant scalar curvature/extremal metric on X\D is asymptotically a product near the divisor.
Aspect and Actuality Entailment: Too and Enough Constructions
Creators: name: Hacquard, Valentine
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper discusses implicative readings of too and enough constructions (TECs), that is, readings where their complement clause is realized in the actual world. There appears to be a correlation between aspect and implication in these constructions: with perfective aspect, TECs are implicatives, with imperfective, they aren’t. I show that previous analyses cannot handle this aspectual interaction, nor derive implicative readings at all. I propose a new analysis, in which the base meaning of TECs is implicative and non modal, and emerges with perfective aspect, while the non implicative readings of TECs arise with imperfective morphology, which I take to be a reflection of a covert genericity operator.

description: Recent advances in measuring and interpreting cosmic rays from the spectral ankle to the highest energies are briefly reviewed. The prime question at the highest energies is about the origin of the flux suppression observed at E ~ 4x10^{19} eV. Is this the long awaited GZK-effect or the exhaustion of sources? The key to answering this question will be provided by the largely unknown mass composition at the highest energies. The high level of isotropy observed even at the highest energies challenges models of a proton dominated composition if extragalactic magnetic fields are on the order of a few nG or less. We shall discuss the experimental and theoretical progress in the field and the prospects for the next decade.

Utilizing the generalized beta prime distributions, we successfully reproduce the relativistic kappa distribution, including the power-law tail. The derivation of the procedure, mathematical preparations, comparison with other procedures, and numerical tests are presented.

description: We analyze diffusion processes with finite propagation speed in a non-homogeneous medium in terms of the heterogeneous telegrapher's equation. In the diffusion limit of infinite-velocity propagation we recover the results for the heterogeneous diffusion process. The heterogeneous telegrapher's process exhibits a rich variety of diffusion regimes including hyperdiffusion, ballistic motion, superdiffusion, normal diffusion and subdiffusion, and different crossover dynamics characteristic for complex systems in which anomalous diffusion is observed. The anomalous diffusion exponent in the short time limit is twice the exponent in the long time limit, in accordance to the crossover dynamics from ballistic diffusion to normal diffusion in the standard telegrapher's process. We also analyze the finite-velocity heterogeneous diffusion process in presence of stochastic Poissonian resetting. We show that the system reaches a non-equilibrium stationary state. The transition to this non-equilibrium steady state is analysed in terms of the large deviation function.

Quantificational Variability Effects with Plural Definites

name: Hinterwimmer, Stefan
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In this paper we give evidence that Quantificational Variability Effects (Berman (1991)) in sentences containing plural definites come about as an indirect effect of quantification over sum eventualities. Evidence for this claim comes from the fact that those sentences – in contrast to minimally varying sentences where the Q-adverb has been replaced by a quantificational determiner – have to obey two newly observed constraints in order to get QV-readings. We show that those constraints can be explained if an analysis that is based on Nakanishi/Romero’s (2004) analysis of the Q-adverb for the most part is combined with the results of Endriss/Hinterwimmer (to appear), where we offer an explanation for similar constraints in adverbially quantified sentences that contain singular indefinites.

description: Die Studie «Gesundheit von Sozialhilfebeziehenden» der Berner Fachhochschule (BFH) und der Zürcher Fachhochschule für Angewandte Wissenschaften (ZHAW) aus dem Jahr 2021 hat gezeigt, dass der physische und psychische Gesundheitszustand von Sozialhilfebeziehenden in der Schweiz im Vergleich zur Restbevölkerung signifikant schlechter ist und sie ein risikoreicheres Gesundheitsverhalten aufweisen. Da alleinerziehende Eltern zu den Personengruppen gehören, die am stärksten von Einkommensarmut betroffen sind, ist der Fokus dieser Bachelor-Arbeit auf sie gerichtet. Es wird der Frage nachgegangen, wie Sozialarbeitende die psychische und physische Gesundheit von alleinerziehenden Eltern fördern können. Gestützt auf Fachliteratur wird einerseits aufgezeigt, wie Armut und Gesundheit in Zusammenhang stehen. Andererseits werden Aspekte betrachtet, welche die Lebenslage alleinerziehender Eltern prägen. Die theoretischen Grundlagen sowie die identifizierten Herausforderungen des Alleinerziehendseins stellen schliesslich die Grundlage für die Handlungsempfehlungen dar. Die Autorin der vorliegenden Bachelor-Arbeit zeigt Sozialarbeitenden der wirtschaftlichen Sozialhilfe somit Handlungsmöglichkeiten auf, die darauf abzielen, die Gesundheit von alleinerziehenden Eltern zu fördern. Es werden Massnahmen erläutert, die auf verschiedenen Ebenen ansetzen. Diese streben eine Verbesserung der Lebensverhältnisse sowie die Erweiterung der Gesundheitskompetenz von Alleinerziehenden an.

description: For a network of generic oscillators with nonlocal topology and symmetry-breaking coupling we establish novel partially coherent inhomogeneous spatial patterns, which combine the features of chimera states (coexisting incongruous coherent and incoherent domains) and oscillation death (oscillation suppression), which we call chimera death. We show that due to the interplay of nonlocality and breaking of rotational symmetry by the coupling two distinct scenarios from oscillatory behavior to a stationary state regime are possible: a transition from an amplitude chimera to chimera death via in-phase synchronized oscillations, and a direct abrupt transition for larger coupling strength.

description: We theoretically and numerically investigate metamaterials composed of coupled resonators with indirect coupling. First, we theoretically analyze a mechanical model of coupled resonators with indirect coupling. The theoretical analysis shows that an electromagnetically induced transparency (EIT)-like phenomenon with a transparency bandwidth narrower than the resonance linewidths of the constitutive resonators can occur in the metamaterial with strong indirect coupling. We then numerically examine the characteristics of the metamaterial composed of coupled cut-wire pairs using a finite-difference time-domain (FDTD) method. The FDTD simulation confirms that an EIT-like transparency phenomenon occurs in the metamaterial owing to indirect coupling. Finally, we compare the results of the theoretical and numerical analyses. The behavior of the EIT-like metamaterial is found to be well described by the mechanical model of the coupled resonators.

description: The main goal of this paper is to defend the claim that ni, the French counterpart of neither and nor is always a negative conjunction which takes part in the negative concord system of French. The interpretation one seems to get for this negative concord ni varies depending on the environment where it occurs: depending on its scope position with respect to other negative expressions in the sentence it may alternate with and, or and and not. The paper considers some consequences of this cameleontic behaviour for theories of negative concord.

description: We investigate the depletion of single-electron states in small molecules under the influence of very short XUV pulses. In N$_2$, for a certain window of XUV energies around 50 eV, we observe a marked occupation inversion, i.e. a situation where depletion of the deepest bound valence electron state is much larger than for any other state. This represents a realistic mechanism which is able to cut, almost instantaneously, a hole into a deep lying state, a situation which is often assumed ad hoc in numerous theoretical studies of energetic ultrafast processes. This occupation inversion furthermore drives a dipole instability, i.e. a spontaneous reappearance of the dipole signal long after the laser pulse is over and the dipole signal has died out. The dipole signal that emerges from this instability can be identified as a particular low-energy structure in photo-electron spectra.

description: We investigate the electronic structure of a complex conventional superconductor, ZrB12 employing high resolution photoemission spectroscopy and ab initio band structure calculations. The experimental valence band spectra could be described reasonably well within the local density approximation. Energy bands close to the Fermi level possess t_(2g) symmetry and the Fermi level is found to be in the proximity of quantum fluctuation regime. The spectral lineshape in the high resolution spectra is complex exhibiting signature of a deviation from Fermi liquid behavior. A dip at the Fermi level emerges above the superconducting transition temperature that gradually grows with the decrease in temperature. The spectral simulation of the dip and spectral lineshape based on a phenomenological self energy suggests a finite electron pair lifetime and a pseudogap above the superconducting transition temperature.

description: In a modern power system with an increasing proportion of renewable energy, wind power prediction is crucial to the arrangement of power grid dispatching plans due to the volatility of wind power. However, traditional centralized forecasting methods raise concerns regarding data privacy-preserving and data islands problem. To handle the data privacy and openness, we propose a forecasting scheme that combines federated learning and deep reinforcement learning (DRL) for ultra-short-term wind power forecasting, called federated deep reinforcement learning (FedDRL). Firstly, this paper uses the deep deterministic policy gradient (DDPG) algorithm as the basic forecasting model to improve prediction accuracy. Secondly, we integrate the DDPG forecasting model into the framework of federated learning. The designed FedDRL can obtain an accurate prediction model in a decentralized way by sharing model parameters instead of sharing private data which can avoid sensitive privacy issues. The simulation results show that the proposed FedDRL outperforms the traditional prediction methods in terms of forecasting accuracy. More importantly, while ensuring the forecasting performance, FedDRL can effectively protect the data privacy and relieve the communication pressure compared with the traditional centralized forecasting method. In addition, a simulation with different federated learning parameters is conducted to confirm the robustness of the proposed scheme.

description: We first point out that the Laia-Tong model realizes the Lieb lattice in the holographic setup. It generates a flat band of sharp particle spectrum together with a Dirac band of unparticle spectrum. We then construct a model which opens a gap to the Dirac band so that one can realize a well-separated flat band, which can play the role of the hydrogen atom of strongly correlated systems. We then study the phase transition between the gapped and gapless phases analytically. We also made methodological progress to find a few other quantizations and we express the Green functions in any quantization in terms of that in the standard quantization.

description: Despite significant efforts devoted to understanding the underlying complexity and emergence of collective movement in animal groups, the role of different external settings on this type of movement remains largely unexplored. Here, by combining time series analysis and complex network tools, we present an extensive investigation of the effects of shady environments on the behavior of a fish species (Silver Carp Hypophthalmichthys molitrix) within earthen ponds. We find that shade encourages fish residence during daylight hours, but the degree of preference for shade varies substantially among trials and ponds. Silver Carp are much slower and exhibit lower persistence in their speeds when under shade than out of it during daytime and nighttime, with fish displaying the highest persistence degree and speeds at night. Furthermore, our research shows that shade affects fish schooling behavior by reducing their polarization, number of interactions among individuals, and the stability among local neighbors; however, fish keep a higher local degree of order when under shade compared to nighttime positions.

description: In this paper, I argue that ‘two’ means ‘exactly two’ and in cases where there is an ‘at least two’ interpretation, this is due to pragmatic presupposition (often about speaker’s grounds). By contrast, I argue that ‘some’ means ‘a quantity (of)’. Where there is an ‘and not all’ interpretation this is due to pragmatic inference/implicature (about speaker’s grounds) based on some kind of Gricean Quantity maxim/principle - even in cases where the implicature is embedded.

description: The dynamics of stochastic reaction networks within cells are inevitably modulated by factors considered extrinsic to the network such as for instance the fluctuations in ribsome copy numbers for a gene regulatory network. While several recent studies demonstrate the importance of accounting for such extrinsic components, the resulting models are typically hard to analyze. In this work we develop a general mathematical framework that allows to uncouple the network from its dynamic environment by incorporating only the environment's effect onto the network into a new model. More technically, we show how such fluctuating extrinsic components (e.g., chemical species) can be marginalized in order to obtain this decoupled model. We derive its corresponding process- and master equations and show how stochastic simulations can be performed. Using several case studies, we demonstrate the significance of the approach. For instance, we exemplarily formulate and solve a marginal master equation describing the protein translation and degradation in a fluctuating environment.

On the Common Format of Eventives and 'Too'-Comparatives
Creators: name: Brandt, Patrick
Publisher: name: Proceedings of Sinn und Bedeutung

description: Should events be conceived of as primitive or should they be decomposed into more basic elements with certain syntax? This talk presents new evidence for the latter view: If events are represented as contradictory propositional meanings representing their pre- and post states, a uniform analysis of certain eventive and certain too- comparative constructions is possible; this is wanted given striking parallels between the two types of structure. The analysis goes some way, among other, toward explaining ‘repetetive/restitutive’ asymmetries familiar from eventive constructions (von Stechow 1996) but similarly arising in too- comparative constructions.

A theory of quantum (statistical) measurement

description: We propose a theory of quantum (statistical) measurement which is close, in spirit, to Hepp's theory, which is centered on the concepts of decoherence and macroscopic (classical) observables, and apply it to a model of the Stern-Gerlach experiment. The number N of degrees of freedom of the measuring apparatus is such that $N \to \infty$, justifying the adjective "statistical", but, in addition, and in contrast to Hepp's approach, we make a three-fold assumption: the measurement is not instantaneous, it lasts a finite amount of time and is, up to arbitrary accuracy, performed in a finite region of space, in agreement with the additional axioms proposed by Basdevant and Dalibard. It is then shown how von Neumann's "collapse postulate" may be avoided by a mathematically precise formulation of an argument of Gottfried, and, at the same time, Heisenbeg's "destruction of knowledge" paradox is eliminated. The fact that no irreversibility is attached to the process of measurement is shown to follow from the author's theory of irreversibility, formulated in terms of the mean entropy, due to the latter's property of affinity.

description: The MnAs compound shows a first-order transition at T$_C\approx42$ C, and a second-order transition at T$_t\approx120$ C. The first-order transition, with structural (hexagonal-orthorhombic), magnetic (FM-PM) and electrical conductivity changes, is associated to magnetocaloric, magnetoelastic, and magnetoresistance effects. We report a study in a large temperature range from $-196$ up to $140$ C, using the $γ-γ$ perturbed angular correlations method with the radioactive probe $^{77}$Br$\rightarrow^{77}$Se, produced at the ISOLDE-CERN facility. The electric field gradients and magnetic hyperfine fields are determined across the first- and second-order phase transitions encompassing the pure and mixed phase regimes in cooling and heating cycles. The temperature irreversibility of the 1st order phase transition is seen locally, at the nanoscopic scale sensitivity of the hyperfine field, by its hysteresis, detailing and complementing information obtained with macroscopic measurements (magnetization and X-ray powder diffraction). To interpret the results, hyperfine parameters were obtained with first-principles spin-polarized density functional calculations using the generalized gradient approximation with the full potential (L)APW+lo method (\textsc{Wien2k} code) by considering the Se probe at both Mn and As sites. A clear assignment of the probe location at the As site is made and complemented with the calculated densities of states and local magnetic moments. We model electronic and magnetic properties of the chemically similar MnSb and MnBi compounds, complementing previous calculations.

Negative Bias in Polar Questions

Year: 2019

description: This paper investigates the discourse function of negative bias in questions. How and what such questions contribute to the logical form of discourse has not been the focus of previous work. We believe that such a discourse oriented approach, however, provides useful insight into the formal characteristics of bias. Adopting this perspective, we develop an analysis of biased questions as complex speech acts, i.e. illocutionary acts comprised of both an assertion and a question. This analysis, we feel, is useful in accounting for the behavior of biased questions in discourse and dialogue.

description: Quantum fluctuations are the key concepts of quantum mechanics. Quantum fluctuations of quantum fields induce a zero-point energy shift under spatial boundary conditions. This quantum phenomenon, called the Casimir effect, has been attracting much attention beyond the hierarchy of energy scales, ranging from elementary particle physics to condensed matter physics together with photonics. However, the application of the Casimir effect to spintronics has not yet been investigated enough, particularly to ferrimagnetic thin films, although yttrium iron garnet (YIG) is one of the best platforms for spintronics. Here we fill this gap. Using the lattice field theory, we investigate the Casimir effect induced by quantum fields for magnons in insulating magnets and find that the magnonic Casimir effect can arise not only in antiferromagnets but also in ferrimagnets including YIG thin films. Our result suggests that YIG, the key ingredient of magnon-based spintronics, can serve also as a promising platform for manipulating and utilizing Casimir effects, called Casimir engineering. Microfabrication technology can control the thickness of thin films and realize the manipulation of the magnonic Casimir effect. Thus, we pave the way for magnonic Casimir engineering.

description: We study the orbits and manifolds near the equilibrium points of a rotating asteroid. The linearised equations of motion relative to the equilibrium points in the gravitational field of a rotating asteroid, the characteristic equation and the stable conditions of the equilibrium points are derived and discussed. First, a new metric is presented to link the orbit and the geodesic of the smooth manifold. Then, using the eigenvalues of the characteristic equation, the equilibrium points are classified into 8 cases. A theorem is presented and proved to describe the structure of the submanifold as well as the stable and unstable behaviours of a massless particle near the equilibrium points. The linearly stable, the non-resonant unstable, and the resonant equilibrium points are discussed. There are three families of periodic orbits and four families of quasi-periodic orbits near the linearly stable equilibrium point. For the non-resonant unstable equilibrium points, there are four cases; for the periodic orbit and the quasi-periodic orbit, the structures of the submanifold and the subspace near the equilibrium points are studied for each case. For the resonant equilibrium points, the dimension of the resonant manifold is greater than four, and we find at least 1 family of periodic orbits near the resonant equilibrium points. Besides, this theory is applied to asteroids 216 Kleopatra, 1620 Geographos, 4769 Castalia, and 6489 Golevka.
Presupposition Incorporation in Adverbial Quantifier Domains
Creators: name: Ahn, David D.
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper proposes a novel solution to the problem of determining the domain of an adverbial quantifier. We observe that adverbial and nominal quantification differ with respect to their ability to incorporate presuppositions into their domain restrictions, and we use that observation to motivate an account of qadverbs as quantifiers over polar alternatives. Along the way to explaining incorporation, we also provide an analysis of presupposing achievement verbs that clarifies the connection between presupposed and asserted situations.

Time Evolution of a Decaying Quantum State: Evaluation and Onset of Non-Exponential Decay

description: The method developed by Van Dijk, Nogami and Toyama for obtaining the time-evolved wave function of a decaying quantum system is generalized to potentials and initial wave functions of non-compact support. The long time asymptotic behavior is extracted and employed to predict the timescale for the onset of non-exponential decay. The method is illustrated with a Gaussian initial wave function leaking through Eckart's potential barrier on the halfline.
Remarks on Grimshaw’s Clausal Typology
Creators: name: Abels, Klaus
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In this paper the question is raised whether Grimshaw’s clause type feature [E] is necessary to capture Generalizations I and II. Generalization I follows directly from independently motivated presuppositions of surprise-predicates once the (nonstandard) assumption is made that polar interrogatives are singleton sets of proposition. The first part of this paper thus constitutes an argument for this approach to polar interrogatives. In fn. 9 we note that this approach to polar interrogatives also solves one of Krifka’s objections to the proposition set approach to questions – which constitutes a second argument. Generalization II also seems to be analyzable in terms of presuppositions, those of wonder-predicates and intensified questions. D’Avis’ intuition that intensified questions are defective appears to lead to a workable result once d’Avis specific implementation is abandoned. A new argument for this view comes from the fact that filters for presuppositions interact in the expected way with acceptability judgments.
