description: In [Dugan-Glennon-Gunnells-Steingrimsson-2019], the authors introduce tiered trees to define combinatorial objects counting absolutely indecomposable representations of certain quivers, and torus orbits on certain homogeneous varieties. In this paper, we use Theta operators, introduced in [D'Adderio-Iraci-VandenWyngaerd-Theta-2021], to give a symmetric function formula that enumerates these trees. We then formulate a general conjecture that extends this result, a special case of which might give some insight about how to formulate a unified Delta conjecture [Haglund-Remmel-Wilson-2018].
Salutogenese und Lebensqualität von Menschen mit einer kognitiven Beeinträchtigung: Handlungsempfehlungen für die Sozialpädagogik in Wohnsettings
Creators: name: Bögli, Doris
Publisher: name: Zenodo

description: Die Förderung der Lebensqualität ist ein zentrales Ziel der sozialpädagogischen Arbeit mit Menschen, welche in speziellen Abhängigkeitsverhältnissen leben. Die vorliegende Literaturarbeit beschäftigt sich mit der Frage, wie die Lebensqualität von erwachsenen Menschen mit einer kognitiven Beeinträchtigung im Wohnsetting unter Einbezug der Salutogenese sozialpädagogisch gefördert werden kann. Was Lebensqualität für Menschen mit einer kognitiven Beeinträchtigung grundsätzlich beinhaltet, wird anhand des Lebensqualitätsmodells von Curaviva aufgezeigt. Die Sozialpädagogik orientiert sich bei ihrer Arbeit unter anderem an Leitprinzipien, mit der Absicht, das übergeordnete Ziel der Erhaltung und Optimierung der Lebensqualität der Klientel zu erreichen. Die Theorie der Salutogenese weist zahlreiche Parallelen zu diesen sozialpädagogischen Leitprinzipien auf und ist aufgrund des dahinterliegenden, ganzheitlichen Gesundheitsverständnisses und der Fokussierung auf die Ressourcen gut geeignet, um die Lebensqualität der Klientel zu verbessern. Die Autorin zeigt in dieser Arbeit auf, dass eine Orientierung an der Theorie der Salutogenese Einfluss auf Aspekte von Lebensqualität hat und wie die Theorie in sozialpädagogischen Wohnsettings für Menschen mit einer kognitiven Beeinträchtigung konkret angewendet werden kann. Vermitteln Sozialpädagog:innen beispielsweise Informationen verständlich, fördern sie die Klientel bewusst und ohne diese zu überfordern, bestärken sie sie im Verfolgen von persönlichen Zielen und ermöglichen sie eine möglichst hohe Selbst- und Mitbestimmung, so kann dies die individuelle Lebensqualität steigern.

description: Usually, we expect large particles to sediment faster than small of the same material. Contrary to this intuition, we report a dynamical competition between sedimentation and phase ordering which leads to smaller particles settling faster than larger ones. We access this phenomenon using suspensions of polymers and two colloidal species which we image with confocal microscopy. Polymers mediate attractions between colloids, leading to phase separation and crystallisation. We find that the dynamical interplay between sedimentation, phase separation and crystal nucleation underlie this phenomenon. Furthermore, under certain conditions we find a kinetic pathway leading to an apparent coexistence between a one component crystal and binary fluid of equal buoyancy. These findings may be relevant to the basic understanding of sedimentation-induced zone formation in nature and industrial applications.

description: We study the performance of Markov chains for the $q$-state ferromagnetic Potts model on random regular graphs. It is conjectured that their performance is dictated by metastability phenomena, i.e., the presence of "phases" (clusters) in the sample space where Markov chains with local update rules, such as the Glauber dynamics, are bound to take exponential time to escape. The phases that are believed to drive these metastability phenomena in the case of the Potts model emerge as local, rather than global, maxima of the so-called Bethe functional, and previous approaches of analysing these phases based on optimisation arguments fall short of the task. Our first contribution is to detail the emergence of the metastable phases for the $q$-state Potts model on the $d$-regular random graph for all integers $q,d\geq 3$, and establish that for an interval of temperatures, which is delineated by the uniqueness and a broadcasting threshold on the $d$-regular tree, the two phases coexist. The proofs are based on a conceptual connection between spatial properties and the structure of the Potts distribution on the random regular graph, rather than complicated moment calculations. Based on this new structural understanding of the model, we obtain various algorithmic consequences. We first complement recent fast mixing results for Glauber dynamics by Blanca and Gheissari below the uniqueness threshold, showing an exponential lower bound on the mixing time above the uniqueness threshold. Then, we obtain tight results even for the non-local Swendsen-Wang chain, where we establish slow mixing/metastability for the whole interval of temperatures where the chain is conjectured to mix slowly on the random regular graph. The key is to bound the conductance of the chains using a random graph "planting" argument combined with delicate bounds on random-graph percolation.

description: Using density matrix renormalization group simulations on open chains, we map out the wave-vector in the incommensurate disordered phase of a realistic model of Rydberg chains with $1/r^6$ interactions, and we locate and characterize the points along the commensurate lines where the transition out of the period 3 and 4 phases is conformal. We confirm that it is 3-state Potts for the period-3 phase, and we show that it is Ashkin-Teller with $ν\simeq 0.80$ for the period-4 phase. We further show that close to these points the transition is still continuous, but with a completely different scaling of the wave-vector, in agreement with a chiral transition. Finally, we propose to use the conformal points as benchmarks for Kibble-Zurek experiments, defining a roadmap towards a conclusive identification of the chiral universality class.

description: With the High Luminosity LHC coming online in the near future, event generators will need to provide very large event samples to match the experimental precision. Currently, the estimated cost to generate these events exceeds the computing budget of the LHC experiments. To address these issues, the computing efficiency of event generators need to be improved. Many different approaches are being taken to achieve this goal. I will cover the ongoing work on implementing event generators on the GPUs, machine learning the matrix element, machine learning the phase space, and minimizing the number of negative weight events.

description: In this article we present the quantization process for Schwarzschild space-time in the context of Teleparallel gravity. In order to achieve such a goal we use the Weyl formalism that establishes a well defined correspondence between classical quantities which are realized by functions and quantum ones which are realized by operators. In the process of quantization we introduce a fundamental constant that is used to construct what we call the quantum of matter by the imposition of periodic conditions over the eigenfunction.

description: The design for an inductive superconducting quantum interference proximity transistor with enhanced performance, the L-SQUIPT, is presented and analyzed. The interferometer is based on a double-loop structure, where each ring comprises a superconductor-normal metal-superconductor mesoscopic Josephson weak-link and the read-out electrode is implemented in the form of a superconducting tunnel probe. Our design allows both to improve the coupling of the transistor to the external magnetic field and to increase the characteristic magnetic flux transfer functions, thereby leading to an improved ultrasensitive quantum limited magnetometer. The L-SQUIPT behavior is analyzed in both the dissipative and the dissipationless Josephson-like operation modes, in the dissipative or in the dissipationless Josephson-like operation mode in the latter case by exploiting both an inductive and a dispersive readout scheme. The improved performance makes the L-SQUIPT promising for magnetic field detection as well as for specific applications in quantum technology, where a responsive dispersive magnetometry at milliKelvin temperatures is required.

description: The LUXE experiment (LASER Und XFEL Experiment) is a new experiment in planning at DESY Hamburg, which will study Quantum Electrodynamics (QED) at the strong-field frontier. In this regime, QED is non-perturbative. This manifests itself in the creation of physical electron-positron pairs from the QED vacuum. LUXE intends to measure the positron production rate in this unprecedented regime by using, among others, a silicon tracking detector. The large number of expected positrons traversing the sensitive detector layers results in an extremely challenging combinatorial problem, which can become computationally very hard for classical computers. This paper presents a preliminary study to explore the potential of quantum computers to solve this problem and to reconstruct the positron trajectories from the detector energy deposits. The reconstruction problem is formulated in terms of a quadratic unconstrained binary optimisation. Finally, the results from the quantum simulations are discussed and compared with traditional classical track reconstruction algorithms.

description: Fully general-relativistic binary-neutron-star (BNS) merger simulations with quark-hadron crossover (QHC) equations of state (EOSs) are studied for the first time. In contrast to EOSs with purely hadronic matter or with a first-order quark-hadron phase transition (1PT), in the transition region QHC EOSs show a peak in sound speed, and thus a stiffening. We study the effects of such stiffening in the merger and post-merger gravitational (GW) signals. Through simulations in the binary-mass range $2.5 < M/M_{\odot} < 2.75$, characteristic differences due to different EOSs appear in the frequency of the main peak of the post-merger GW spectrum ($f_2$), extracted through Bayesian inference. In particular, we found that (i) for lower-mass binaries, since the maximum baryon number density ($n_{\rm max}$) after the merger stays below $3\text{--}4$ times the nuclear-matter density ($n_0$), the characteristic stiffening of the QHC models in that density range results in a lower $f_2$ than that computed for the underlying hadronic EOS and thus also than that for EOSs with a 1PT, (ii) for higher-mass binaries, where $n_{\rm max}$ may exceed $4\text{--}5 n_0$ depending on the EOS model, whether $f_2$ in QHC models is higher or lower than that in the underlying hadronic model depends on the height of the sound-speed peak. Comparing the values of $f_2$ for different EOSs and BNS masses gives important clues on how to discriminate different types of quark dynamics in the high-density end of EOSs and is relevant to future kilohertz GW observations with third-generation GW detectors.

description: Recently, graph neural networks (GNNs) have been successfully used for a variety of particle reconstruction problems in high energy physics, including particle tracking. The Exa.TrkX pipeline based on GNNs demonstrated promising performance in reconstructing particle tracks in dense environments. It includes five discrete steps: data encoding, graph building, edge filtering, GNN, and track labeling. All steps were written in Python and run on both GPUs and CPUs. In this work, we accelerate the Python implementation of the pipeline through customized and commercial GPU-enabled software libraries, and develop a C++ implementation for inferencing the pipeline. The implementation features an improved, CUDA-enabled fixed-radius nearest neighbor search for graph building and a weakly connected component graph algorithm for track labeling. GNNs and other trained deep learning models are converted to ONNX and inferenced via the ONNX Runtime C++ API. The complete C++ implementation of the pipeline allows integration with existing tracking software. We report the memory usage and average event latency tracking performance of our implementation applied to the TrackML benchmark dataset.

General properties of the radiation spectra from relativistic electrons moving in a Langmuir turbulence

description: We examine the radiation spectra from relativistic electrons moving in a Langmuir turbulence expected to exist in high energy astrophysical objects by using numerical method. The spectral shape is characterized by the spatial scale λ, field strength σ, and frequency of the Langmuir waves, and in term of frequency they are represented by ω_0 = 2πc/λ, ω_st = eσ/mc, and ω_p, respectively. We normalize ω_st and ω_p by ω_0 as \a \equiv ω_st/ω_0 and \b \equivω_p/ω_0, and examine the spectral shape in the a-b plane. An earlier study based on Diffusive Radiation in Langmuir turbulence (DRL) theory by Fleishman and Toptygin showed that the typical frequency is γ^2ω_p and that the low frequency spectrum behaves as F_ω pronto ω^1 for b > 1 irrespective of a. Here, we adopt the first principle numerical approach to obtain the radiation spectra in more detail. We generate Langmuir turbulence by superposing Fourier modes,inject monoenergetic electrons, solve the equation of motion, and calculate the radiation spectra using Lienard-Wiechert potential. We find different features from the DRL theory for a>b>1. The peak frequency turns out to be γ^2ω_st which is higher than γ^2ω_p predicted in the DRL theory, and the spectral index of low frequency region is not 1 but 1/3. It is because the typical deflection angle of electrons is larger than the angle of the beaming cone sim 1/γ. We call the radiation for this case "Wiggler Radiation in Langmuir turbulence" (WRL).

description: We construct a countable p-local group with a proper invariant metric whose Assouad-Nagata dimension is strictly greater than the asymptotic dimension with linear control. This solves Problem 8.6 from the list [Dr]. We study asymptotic dimension with linear control $\ell$-$asdim_ω$ that depends on a fixed ultrafilter on the naturals. It turns out that the Assouad-Nagata dimension is the supremum of $\ell$-$asdim_ω$ on all $ω$ and the asymptotic dimension with linear control is the minimum.

description: Composing Graph Neural Networks (GNNs) of operations that respect physical symmetries has been suggested to give better model performance with a smaller number of learnable parameters. However, real-world applications, such as in high energy physics have not born this out. We present the novel architecture VecNet that combines both symmetry-respecting and unconstrained operations to study and tune the degree of physics-informed GNNs. We introduce a novel metric, the \textit{ant factor}, to quantify the resource-efficiency of each configuration in the search-space. We find that a generalized architecture such as ours can deliver optimal performance in resource-constrained applications.

description: Photo nuclear reactions are shown to be used for studying neutrino/weak nuclear responses involved in astro-neutrino nuclear interactions and double beta decays. Charged current weak responses for ground and excited states are studied by using photo nuclear reactions through isobaric analog states of those states, while neutral current weak responses for excited states are studied by using photo nuclear reactions through the excited states. The weak interaction strengths are studied by measuring the cross sections of the photo nuclear reactions, and the spin and parity of the state are studied by measuring angular correlations of particles emitted from the photo nuclear reactions. Medium-energy polarized photons obtained from laser photons scattered off GeV electrons are very useful. Nuclear responses studied by photo nuclear reactions are used to evaluate neutrino/weak nuclear responses, i.e. nuclear beta and double beta matrix elements and neutrino nuclear interactions, and to verify theoretical calculations for them.

Genetic studies (Nishikawa et al. 2014) have confirmed the distinction between this species and A. aspersa, to which it is very similar and the two species share the same type locality. It is likewise considered invasive in Japan but has been listed as cryptogenic in the Mediterranean (López-Legentil and Legentil 2015). It should be considered cryptogenic in British waters until its origin has been determined.

description: The two objects 1SWASP J150822.80-054236.9 and 1SWASP J160156.04+202821.6 were initially detected from their SuperWASP archived light curves as candidate eclipsing binaries with periods close to the short-period cut-off of the orbital period distribution of main sequence binaries, at ~0.2 d. Here, using INT spectroscopic data, we confirm them as double-lined spectroscopic and eclipsing binaries, in contact configuration. Following modelling of their visual light curves and radial velocity curves, we determine their component and system parameters to precisions between ~2 and 11%. The former system contains 1.07 and 0.55 M_sun components, with radii of 0.90 and 0.68 R_sun respectively; its primary exhibits pulsations with period 1/6 the orbital period of the system. The latter contains 0.86 and 0.57 M_sun components, with radii of 0.75 and 0.63R_sun respectively.

description: We consider a typical circuit QED setup where an artificial atom encodes a qubit and is dispersively coupled to a measurement resonator that in turn is coupled to a transmission line. We show theoretically that by placing another artificial atom in this transmission line to act as a filter, the Purcell decay of the qubit into the transmission line is suppressed. When strong control fields are applied in the transmission line, the filter is saturated and effectively switched off. Such a Purcell filtering capability permits both the control and measurement of the qubit using the single transmission line, while maintaining the long coherence time of the qubit in the absence of the control pulses. We show that high fidelity Pauli $σ_x$ gates on the qubit can be realized using simple pulse shapes. For devices that already use one transmission line both for control and measurement of the qubit, our work provides a way to completely filter out the qubit frequency without removing the possibility of controlling the system. Further, combining the proposed filter with frequency multiplexing potentially enables both control and measurement of several qubits using a single Purcell-filtered transmission line. This will enhance the scalability of superconducting quantum processors by decreasing the number of the required transmission lines.

description: The electronic and topological properties of single-layer X3YZ6 (X=Nb,Ta, Y=Si,Ge,Sn, Z=S,Se,Te) materials have been studied with the aid of first principles calculations. This kind of materials belong to topological semimetals (TMs) with abundant nodal lines and nodes. Considering their similar properties, we focus on the analysis of Ta3SnTe6 and Ta3SiSe6. The present of spin-orbit coupling (SOC) leads to the transition from type-I nodal lines to Dirac points as well as the disappear of type-II Dirac points. The three-dimensional (3D) band diagrams reproduce vividly the characteristics of nodes and nodal lines. The appearance of the flat bands in (110) edge states further confirm their nontrivial topological properties. We also explore the relationship among different nodal lines (nodes), crystal symmetry and SOC. The type-I nodal lines are protected by Mz and My symmetry in the absent of SOC. Symmetry breaking leads to band splitting even in the presence of SOC. The single-layer X3YZ6 can be used as candidates for two-dimensional (2D) TMs and provide a platform for further study of interesting physical phenomena.

Licensing and Interpretation of n-words in Comparative Clauses

description: The available analysis of comparative constructions that intend to explain the possibility of NPIs to occur in than-clauses do not give a satisfactory account of the licensing and interpretation of N-words in such clauses. In this paper, I propose a different analysis of comparative constructions, which, contrary to previous analysis, does not assume any stipulation particular to such structures, such as some rule that reverses the scope relations between different elements. This is achieved by considering that the semantics of comparative constructions involves the consideration of three degrees. The proposed analysis explains naturally the presence and interpretation of N-words in than-clauses.

description: Continual learning, also known as lifelong learning, is an emerging research topic that has been attracting increasing interest in the field of machine learning. With human activity recognition (HAR) playing a key role in enabling numerous real-world applications, an essential step towards the long-term deployment of such recognition systems is to extend the activity model to dynamically adapt to changes in people's everyday behavior. Current research in continual learning applied to HAR domain is still under-explored with researchers exploring existing methods developed for computer vision in HAR. Moreover, analysis has so far focused on task-incremental or class-incremental learning paradigms where task boundaries are known. This impedes the applicability of such methods for real-world systems since data is presented in a randomly streaming fashion. To push this field forward, we build on recent advances in the area of continual machine learning and design a lifelong adaptive learning framework using Prototypical Networks, LAPNet-HAR, that processes sensor-based data streams in a task-free data-incremental fashion and mitigates catastrophic forgetting using experience replay and continual prototype adaptation. Online learning is further facilitated using contrastive loss to enforce inter-class separation. LAPNet-HAR is evaluated on 5 publicly available activity datasets in terms of the framework's ability to acquire new information while preserving previous knowledge. Our extensive empirical results demonstrate the effectiveness of LAPNet-HAR in task-free continual learning and uncover useful insights for future challenges.

Publisher: name: Zenodo
Year: 2017

description: Every firm without good marketing team and strategies is bound to fail. In order to be competitive and profitable in the industry, bankers should acquire and retain profitable customers. Definitely this is done with relationship marketing. Relationship marketing is a philosophy of doing business, a strategic orientation that focuses on keeping and improving current customers rather than acquiring new customers. Therefore, relationship marketing has become more and more important since last decade of 20th century, especially in service industry. This research was conducted to investigate the effect of relationship marketing on customer’s loyalty in the banking industry in Ethiopia the case of commercial banks in Sebeta city municipality town. There are many relationship marketing dimensions implemented for retaining customers. This study was aimed to explore the effect of relationship marketing dimensions (trust, commitment, conflict handling and empathy) on customers’ loyalty in banking industry in Ethiopia the case of commercial banks in Sebeta city municipality town
'Be' the One

Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper presents an analysis of the semantics of be in which the verb only contains an argument position. In a sense, the function of this verb is to introduce a subject in a proposition. Different readings of the verbs are accounted for by assuming that the rules that combine the verb with other terms introduce semantic distinctions, the restrictions on what is possible being determined by the capacity of the representation constructed to relate to a situation in the world. The analysis emerges from the assumption that an adequate description of a term should not refer to contingent properties—that is, properties the term only has in specific context—a position that, when pushed to its logical conclusion, leads to articulate the sound-meaning relation in grammar in a different light than what is generally assumed in traditional frameworks.

description: Strongly correlated electron systems host a variety of poorly understood correlations in their high temperature normal state. Unlike ordered phases defined by order parameters, these normal state phases are often defined through unconventional properties such as strange metallic transport or spectroscopic pseudogaps. Characterizing the microscopic correlations in the normal state is necessary to elucidate mechanisms that lead to these properties and their connection to ground state orders. Here we establish the presence of intertwined charge and spin stripes in the strange metal normal state of the Hubbard model using determinant quantum Monte Carlo calculations. The charge and spin density waves constituting the stripes are fluctuating and short-ranged, yet they obey a mutual commensurability relation and remain microscopically interlocked, as evidenced through measurements of three-point spin-spin-hole correlation functions. Our findings demonstrate the ability of many-body numerical simulations to unravel the microscopic correlations that define quantum states of matter.
Producer Interpretations of the English Pre-Nominal Genitive
Creators: name: Jensen, Per Anker
name: Vikner, Carl
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper presents a theory of the pre-nominal genitive in English based on the claims that it is argument-only and polymorphic, on the one hand allowing a control interpretation delivered by ‘s itself, and, on the other hand, three ‘constructional interpretations’: an inherently relational, a partwhole, and a producer interpretation delivered by the head noun of the genitive construction. The paper addresses four types of evidence seeming to raise problems for the claim that producer interpretations are semantic, i.e. available as default interpretations, rather than pragmatic. We argue that in spite of this evidence, the hypothesis can be upheld. Finally, independent evidence is adduced concerning the semantics of the Hebrew Construct State Construction, which allows precisely the range of semantic interpretations we have proposed for the English pre-nominal genitive, including the producer interpretation, while not allowing pragmatic interpretations.

On the Interpretation of Stressed Pronouns
Creators: name: De Hoop, Helen
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In this paper I will argue that meaning effects of stress on pronouns are general interpretive effects of constituent focus. I propose two constraints, Contrastive Stress and Continuing Topic, to deal with the interpretation of stressed pronouns in English. These two constraints and their interaction also account for some well-known data that are usually analysed via the Complementary Preference Hypothesis.

Higher rank parabolic geometries with essential automorphisms and nonvanishing curvature

description: We construct infinite families of regular normal Cartan geometries with nonvanishing curvature and essential automorphisms on closed manifolds for many higher rank parabolic model geometries. To do this, we use particular elements of the kernel of the Kostant Laplacian to construct homogeneous Cartan geometries of the desired type, giving a global realization of an elegant local construction due to Kruglikov and The, and then modify these homogeneous geometries to make their base manifolds compact. As a demonstration, we apply the construction to quaternionic contact structrures of mixed signature, among other examples.

Plural Pronouns with Quantified Antecedents
Creators: name: Hardt, Daniel
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: It is well known that plural pronouns can have quantified antecedents which do not c-command them. While both Heim’s E-type approach and DRT’s Abstraction approach can handle some cases of this, there are certain cases neither approach can handle, when the quantified antecedent is embedded with the scope of another quantifier. We show how both approaches can be modified to solve the problem.

description: Deeply Virtual Compton Scattering in the near forward kinematic region is the golden access to Generalized Parton Distributions. We studied the O(alphaS) corrections to the scattering amplitude for both spacelike and timelike kinematics relevant respectively to the leptoproduction of a real photon and to the photoproduction of a lepton pair. It turns out that these corrections are phenomenologically important and that the gluonic contributions are by no means negligible, even in the moderate energy range of JLab12 and of the COMPASS-II experiment at CERN.

description: Normalizing Flows (NFs) are emerging as a powerful class of generative models, as they not only allow for efficient sampling, but also deliver, by construction, density estimation. They are of great potential usage in High Energy Physics (HEP), where complex high dimensional data and probability distributions are everyday's meal. However, in order to fully leverage the potential of NFs it is crucial to explore their robustness as data dimensionality increases. Thus, in this contribution, we discuss the performances of some of the most popular types of NFs on the market, on some toy data sets with increasing number of dimensions.

description: The usefulness of deep learning models in robotics is largely dependent on the availability of training data. Manual annotation of training data is often infeasible. Synthetic data is a viable alternative, but suffers from domain gap. We propose a multi-step method to obtain training data without manual annotation effort: From 3D object meshes, we generate images using a modern synthesis pipeline. We utilize a state-of-the-art image-to-image translation method to adapt the synthetic images to the real domain, minimizing the domain gap in a learned manner. The translation network is trained from unpaired images, i.e. just requires an un-annotated collection of real images. The generated and refined images can then be used to train deep learning models for a particular task. We also propose and evaluate extensions to the translation method that further increase performance, such as patch-based training, which shortens training time and increases global consistency. We evaluate our method and demonstrate its effectiveness on two robotic datasets. We finally give insight into the learned refinement operations.
An Asymmetric Universal in Child Language
Creators: name: Gualmini, Andrea
name: Meroni, Luisa

Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Investigations of sentences with the universal quantifier every have led to qualitatively different conclusions about children's linguistic knowledge. The aim of this paper is to investigate the extent to which children know the semantics of the universal quantifier every. A Truth Value Judgment task was conducted to determine whether young children know that the two arguments of the universal quantifier every differ in that only the restrictor, and not the nuclear scope, is downward entailing. Taken together with previous research, the experimental findings suggest that children’s knowledge of the universal quantifier every runs deep, and includes the asymmetry in interpretation between the restrictor and the nuclear scope. The findings challenge recent claims that children lack knowledge of quantification.

Chaotic resonance modes in dielectric cavities: Product of conditionally invariant measure and universal fluctuations

description: We conjecture that chaotic resonance modes in scattering systems are a product of a conditionally invariant measure from classical dynamics and universal exponentially distributed fluctuations. The multifractal structure of the first factor depends strongly on the lifetime of the mode and describes the average of modes with similar lifetime. The conjecture is supported for a dielectric cavity with chaotic ray dynamics at small wavelengths, in particular for experimentally relevant modes with longest lifetime. We explain scarring of the vast majority of modes along segments of rays based on multifractality and universal fluctuations, which is conceptually different from periodic-orbit scarring.
