description: A complex network processing information or physical flows is usually characterized by a number of macroscopic quantities such as the diameter and the betweenness centrality. An issue of significant theoretical and practical interest is how such a network responds to sudden changes caused by attacks or disturbances. By introducing a model to address this issue, we find that, for a finite-capacity network, perturbations can cause the network to \emph{oscillate} persistently in the sense that the characterizing quantities vary periodically or randomly with time. We provide a theoretical estimate of the critical capacity-parameter value for the onset of the network oscillation. The finding is expected to have broad implications as it suggests that complex networks may be structurally highly dynamic.

description: We systematically analyze the effects of the derivatives of the hydrodynamic fields on axial Wigner function that describes the spin polarization vector in phase space. We have included all possible first-order derivative contributions that are allowed by symmetry and compute the associated transport functions at one-loop using the linear response theory. In addition to reproducing known effects due to the temperature gradient and vorticity, we have identified a number of potentially significant contributions that are overlooked previously. In particular, we find that the shear strength, the symmetric and traceless part of the flow gradient, will induce a quadrupole for spin polarization in the phase space. We refer to this novel effect as the shear-induced polarization (SIP). Our results, together with hydrodynamic gradients obtained from hydrodynamic simulations, can be employed as a basis for the interpretation of the $Λ$ (anti-$Λ$) spin polarization measurement in heavy-ion collisions.

Experiments with withdrawal-induced resonant internal waves
Creators: name: Allan, Gary
Publisher: name: University of British Columbia
Year: 2008

description: Control of natural and artificial reservoirs by means of outlet structures (specifically, dams) has been considered by Imberger (1980). Such control has been proposed on Kootenay Lake in eastern British Columbia, as a means to modify the ecology of the lake. This study considers the feasibility of pumped control of a reservoir and the practical problems associated with application on the lake. The generation of internal waves in a rectangular tank by a pump with sinusoidally modulated flow has been investigated via laboratory experiments. Theory appropriate to internal waves in two layer systems has been presented with an extension to deal with the effect of viscosity. The study shows that modulated pumping is a viable method of generating internal waves experimentally and may have applications in controlled reservoirs on which outflow could be modulated. The period of resonant waves increases with interfacial thickness as does wave amplitude: observed periods ranged from 1.01 to 1.05 times greater than theoretically determined periods for two-layer systems. Theoretical determination of the period is based on consideration of the density structure and boundary conditions of the system under study; one would expect real conditions to produce some variation in the observed period versus the theoretical period. The result above is borne out by observation of the amplitude response curves generated by the data and by calculations of the beat frequencies associated with the forcing and generated waves and agrees approximately with the data of Hyden (1974) and Thorpe (1968). There is some indication that as the interface widens the amplitude response curves sharpen, implying that if one hoped to generate a resonant wave in a system with a thick interface one would have to be closer to the resonant period than in a system with a thinner interface to achieve a similar response. Calculation indicates that, for the peak response, the wave with maximum amplitude, 1.7 to 4 % of the energy input per cycle is present in the wave. Energy input per cycle is determined by integrating instantaneous kinetic energy of the water that is pumped over a cycle. Fourier transforms of the data show response, in some cases, in the 6th harmonic modes of the systems, with a decline in energy from the 1st to 2nd mode of 20 to 25 %, typically. Estimates are presented for the damping coefficients for the systems investigated: the average value is 0.0020 s-1. A brief review of problems associated with a practical application of resonant internal waves forced by flow modulation is presented. Several technical problems exist which need further consideration before the application is undertaken, on Kootenay Lake in eastern British Columbia. It may be practicable to try generating internal waves on a smaller lake or reservoir controlled by a dam as a means of testing the feasibility.

description: This dissertation sets out to explore and unfold the visitor's experience in the museum. We aim to examine how museums provide a setting where informal learning is to be found, considering the practices that museums employ towards this direction. We try to show how modern learning theories are being exploited in museums, what museums offer in education, what is the museum's relationship with school and formal learning, how the classroom is preparing itself for an educational program in a museum or cultural space, how to make use of the visit and participation in a similar program in the museum. We, moreover, look at on how museums, institutionally and by hosting educational activities are granted with the ability to empower participants with theoretical knowledge and practical skills that will give them the opportunity to exploit the potential of museums and cultural spaces for dynamic learning. We will try to showcase this perspective by making use of the advantageous features of the so-called project method, through a proposal for a nutrition educational action inspired by Aristotle's philosophical thinking and cosmological view of the value of food as a creation of gastronomic choice by the past with an extension to the present and the future

description: Let G be a discrete group, and let M be a closed spin manifold of dimension m>3 with pi_1(M)=G. We assume that M admits a Riemannian metric of positive scalar curvature. We discuss how to use the L2-rho invariant and the delocalized eta invariant associated to the Dirac operator on M in order to get information about the space of metrics with positive scalar curvatur1e. In particular we prove that, if G contains torsion and M is congruent 3 mod 4 then M admits infinitely many different bordism classes of metrics with positive scalar curvature. We show that this is true even up to diffeomorphism. If G has certain special properties then we obtain more refined information about the ``size'' of the space of metric of positive scalar curvature, and these results also apply if the dimension is congruent to 1 mod 4. For example, if G contains a central element of odd order, then the moduli space of metrics of positive scalar curvature has infinitely many components, if it is not empty. Some of our invariants are the delocalized eta-invariants introduced by John Lott. These invariants are defined by certain integrals whose convergence is not clear in general, and we show, in effect, that examples exist where this integral definitely does not converge, thus answering a question of Lott. We also discuss the possible values of the rho invariants of the Dirac operator and show that there are certain global restrictions (provided the scalar curvature is positive).

Subjects: cross-cultural comparison; supranationalism; mokken scaling; comparative politics; trust; European Parliament

description: Which policies should the European Union (EU) regulate? Which issues should national governments regulate? This is a crucial issue within the EU. Citizens in EU member states have had little influence on decisions allocating political decision-making powers between the supranational and the national/regional levels. Given this situation, it is important to study the supranationalism of people in different European countries. The issues addressed here are the following:
- How can one determine the supranationalism of European citizens?
- Is the homogeneity of these opinions such that one scale can be used for the whole of Europe?
Data used are obtained from the first round of the European Social Survey. The paper reports on an effort to develop a cumulative (Mokken) scale of supranationalism. The paper concludes that one unique scale does not exist that is applicable to all European countries; however, different cumulative scales can be constructed for four clusters of countries. Finally, cross cultural comparisons are carried out testing different hypotheses relating the level of supranationalism with political trust, age, education and establishment in the area.

description: The aim of the present thesis was to discuss the redesign of the investment services sector, taking into account the developments of the past decades. The legislation that has been developed at both a European and a national level to provide the best possible relationship between investors and money market operators and to protect investors from practices of investment services firms to facilitate their trading with large numbers of people. We introduced the legislative framework for the capital market, we have explained important terms and individual investment services. Then we discussed the ways in which money market operators artificially restrict their obligations and criteria by which their various obligations depending on the pre-contractual or contractual stage. In addition, were examined ways of dealing with these practices and the procedural way for them to be reviewed by the Court. Finally, were discussed supervision issues of the Bank of Greece, ways of Collective Investor Protection and Alternative Dispute Resolution

description: The direct income of owners and tenants of dwellings is not comparable since the owners have a hidden income from the investment in their dwelling. This hidden income is considered a part of the disposable income of owners. It may be predicted with the help of a linear model of the rent. Since such a model must be developed and estimated for tenants with observed market rents a selection bias may occur. The selection bias can be minimised through a Heckman correction. The paper applies the Heckman correction to data from the Swiss Statistics on Income and Living Conditions. The Heckman method is adapted to the survey context, the modeling process including the choice of covariates is explained and the effect of the prediction using the model is discussed.

description: We consider the one-person game of peg solitaire on a triangular board of arbitrary size. The basic game begins from a full board with one peg missing and finishes with one peg at a specified board location. We develop necessary and sufficient conditions for this game to be solvable. For all solvable problems, we give an explicit solution algorithm. On the 15-hole board, we compare three simple solution strategies. We then consider the problem of finding solutions that minimize the number of moves (where a move is one or more consecutive jumps by the same peg), and find the shortest solution to the basic game on all triangular boards with up to 55 holes (10 holes on a side).

description: To improve the performance of a quantum key distribution (QKD) system, high speed, low dark count single photon detectors (or low noise homodyne detectors) are required. However, in practice, a fast detector is usually noisy. Here, we propose a "dual detectors" method to improve the performance of a practical QKD system with realistic detectors: the legitimate receiver randomly uses either a fast (but noisy) detector or a quiet (but slow) detector to measure the incoming quantum signals. The measurement results from the quiet detector can be used to bound eavesdropper's information, while the measurement results from the fast detector are used to generate secure key. We apply this idea to various QKD protocols. Simulation results demonstrate significant improvements in both BB84 protocol with ideal single photon source and Gaussian-modulated coherent states (GMCS) protocol; while for decoy-state BB84 protocol with weak coherent source, the improvement is moderate. We also discuss various practical issues in implementing the "dual detectors" scheme.

description: We measure the Shubnikov-de Haas effect in thin-film Sr$_2$RuO$_4$ grown on an (LaAlO$_3$)$_{0.29}$-(SrAl$_{1/2}$Ta$_{1/2}$O$_3$)$_{0.71}$ (LSAT) substrate. We detect all three known Fermi surfaces and extract the Fermi surface volumes, cyclotron effective masses, and quantum lifetimes. We show that the electronic structure is nearly identical to that of single-crystal Sr$_2$RuO$_4$, and that the quasiparticle lifetime is consistent with the Tc of comparably clean, single-crystal Sr$_2$RuO$_4$. Unlike single-crystal Sr$_2$RuO$_4$, where the quantum and transport lifetimes are roughly equal, we find that the transport lifetime is $1.3\pm0.1$ times longer than the quantum lifetime. This suggests that extended (rather than point) defects may be the dominant source of quasiparticle scattering in these films. To test this idea, we perform cross-sectional STEM and find that out-of-phase boundaries extending the entire thickness of the film occur with a density that is consistent with the quantum mean free path. The long quasiparticle lifetimes make these films ideal for studying the unconventional superconducting state in Sr$_2$RuO$_4$ through the fabrication of devices -- such as planar tunnel junctions and SQUIDs.

description: Mass accretion rate determinations are fundamental for an understanding of the evolution of pre-main sequence star circumstellar disks. Magnetospheric accretion models are used to derive values of the mass accretion rates in objects of very different properties, from brown dwarfs to intermediate-mass stars; we test the validity of these models in the brown dwarf regime, where the stellar mass and luminosity, as well as the mass accretion rate, are much lower than in T Tauri stars. We have measured simultaneously two infrared hydrogen lines, Pab and Brg, in a sample of 16 objects in the star-forming region rho-Oph. The sample inc ludes 7 very low mass objects and brown dwarfs and 9 T Tauri stars. Brown dwarfs where both lines are detected have a ratio Pab/Brg of ~2. Larger values, >=3.5, are only found among the T Tauri stars. The low line ratios in brown dwarfs indicate that the lines cannot originate in the column of gas accreting from the disk onto the star along the magnetic field lines, and we suggest that they form instead in the shocked photosphere, heated to temperatures of ~3500 K. If so, in analogy to veiling estimates in T Tauri stars, the hydrogen infrared line fluxes may provide a reliable measure of the accretion rate in brown dwarfs.

description: We apply a friends-of-friends (FoF) algorithm to identify galaxy clusters and we use the catalog to explore the evolutionary synergy between BCGs and their host clusters. We base the cluster catalog on the dense HectoMAP redshift survey (2000 redshifts deg$^{-2}$). The HectoMAP FoF catalog includes 346 clusters with 10 or more spectroscopic members. We list these clusters and their members (5992 galaxies with a spectroscopic redshift). We also include central velocity dispersions ($σ_{*, BCG}$) for all of the FoF cluster BCGs, a distinctive feature of the HectoMAP FoF catalog. HectoMAP clusters with higher galaxy number density (80 systems) are all genuine clusters with a strong concentration and a prominent BCG in Subaru/Hyper Suprime-Cam images. The phase-space diagrams show the expected elongation along the line-of-sight. Lower-density systems include some false positives. We establish a connection between BCGs and their host clusters by demonstrating that $σ_{*,BCG}/σ_{cl}$ decreases as a function of cluster velocity dispersion ($σ_{cl}$), in contrast, numerical simulations predict a constant $σ_{*, BCG}/σ_{cl}$. Sets of clusters at two different redshifts show that BCG evolution in massive systems is slow over the redshift range $z < 0.4$. The data strongly suggest that minor mergers may play an important role in BCG evolution in these clusters ($σ_{cl} \gtrsim 300$ km s$^{-1}$). For systems of lower mass ($σ_{cl} < 300$ km s$^{-1}$), the data indicate that major mergers may play a significant role. The coordinated evolution of BCGs and their host clusters provides an interesting test of simulations in high density regions of the universe.

description: Meuleman and Billiet (2009) have carried out a simulation study aimed at the question how many countries are needed for accurate multilevel SEM estimation in comparative studies. The authors concluded that a sample of 50 to 100 countries is needed for accurate estimation. Recently, Bayesian estimation methods have been introduced in structural equation modeling which should work well with much lower sample sizes. The current study reanalyzes the simulation of Meuleman and Billiet using Bayesian estimation to find the lowest number of countries needed when conducting multilevel SEM. The main result of our simulations is that a sample of about 20 countries is sufficient for accurate Bayesian estimation, which makes multilevel SEM practicable for the number of countries commonly available in large scale comparative surveys.

description: Finite group extensions offer a natural language to quantum computing. In a nutshell, one roughly describes the action of a quantum computer as consisting of two finite groups of gates: error gates from the general Pauli group P and stabilizing gates within an extension group C. In this paper one explores the nice adequacy between group theoretical concepts such as commutators, normal subgroups, group of automorphisms, short exact sequences, wreath products... and the coherent quantum computational primitives. The structure of the single qubit and two-qubit Clifford groups is analyzed in detail. As a byproduct, one discovers that M20, the smallest perfect group for which the commutator subgroup departs from the set of commutators, underlies quantum coherence of the two-qubit system. One recovers similar results by looking at the automorphisms of a complete set of mutually unbiased bases.

description: Multi-agent path finding (MAPF) determines an ensemble of collision-free paths for multiple agents between their respective start and goal locations. Among the available MAPF planners for workspace modeled as a graph, A*-based approaches have been widely investigated due to their guarantees on completeness and solution optimality, and have demonstrated their efficiency in many scenarios. However, almost all of these A*-based methods assume that each agent executes an action concurrently in that all agents start and stop together. This article presents a natural generalization of MAPF with asynchronous actions (MAPF-AA) where agents do not necessarily start and stop concurrently. The main contribution of the work is a proposed approach called Loosely Synchronized Search (LSS) that extends A*-based MAPF planners to handle asynchronous actions. We show LSS is complete and finds an optimal solution if one exists. We also combine LSS with other existing MAPF methods that aims to trade-off optimality for computational efficiency. Numerical results are presented to corroborate the performance of LSS and the applicability of the proposed method is verified in the Robotarium, a remotely accessible swarm robotics research platform.

description: In a previous work, assuming that the nucleus can be treated as a perfect fluid, we have studied the propagation of perturbations in the baryon density. For a given equation of state we have derived a Korteweg - de Vries (KdV) equation from Euler and continuity equations in non-relativistic hydrodynamics. Here, using a more general equation of state, we extend our formalism to relativistic hydrodynamics.

description: Strongly interacting binary mixtures of superparamagnetic colloidal particles confined to a two-dimensional water-air interface are examined by theory, computer simulation and experiment. The mixture exhibits a partial clustering in equilibrium: in the voids of the matrix of unclustered big particles, the small particles form subclusters with a sponge-like topology which is accompanied by a characteristic small-wave vector peak in the small-small structure factor. This partial clustering is a general phenomenon occurring for strongly coupled negatively non-additive mixtures.

Subjects: logistic response; raking; generalized exponential form; selection model; prediction model; WTADJUST

description: Given a randomly drawn sample, calibration weighting can provide double protection against the selection bias resulting from unit nonresponse.  This means that if either an assumed linear prediction model or an implied unit selection model holds, the resulting estimator will be asymptotically unbiased in some sense. The functional form of the selection model when using linear  alibration adjustment is dubious. We discuss an alternative, nonlinear calibration-weighting procedure and software that can, among other things, implicitly estimate a logistic-response model.

description: Abstract

This study investigates the non-linear dynamics between remittance outflows and key macroeconomic indicators in Gulf Cooperation Council (GCC) countries, utilizing a threshold regression model to uncover distinctive threshold effects. The research builds on the premise that the impact of remittances on macroeconomic indicators is non-linear and varies across different levels of economic development, informed by previous studies on remittance flows, macroeconomic impacts, and threshold models. Employing secondary data from 1960 to 2023, the study uses threshold regression models to analyze the relationship between remittance outflows and macroeconomic indicators, considering different threshold levels to capture non-linear dynamics. The analysis reveals limited evidence of significant non-linear relationships within the examined thresholds, suggesting that the impact of remittances varies insignificantly across different levels of economic development within the GCC context. This research sheds light on the nuanced role of remittances in economic development, offering implications for policymakers in crafting remittance-related policies. It highlights the importance of considering the unique economic contexts of GCC countries when evaluating the impact of remittances. This research contributes to the understanding of the complex role of remittances in GCC economies by employing a threshold analysis approach, offering insights for policymakers on optimizing the economic benefits of remittance flows.
Gauge Freedom in the Path Integral Formalism

description: We investigate 't Hooft's technique of changing the gauge parameter of the linear covariant gauge from the point of view of the path integral with respect to the gauge freedom. Extension of the degrees of freedom allows us to formulate a system with extended gauge symmetry. The gauge fixing for this extended symmetry yields the 't Hooft averaging as a path integral over the additional degrees of freedom. Another gauge fixing is found as a non-abelian analogue of the type II gaugeon formalism of Yokoyama and Kubo. In this connection, the 't Hooft average can be viewed as the analogue of the type I gaugeon formalism. As a result, we obtain gauge covariant formulations of non-abelian gauge theories, which allow us to understand 't Hoot's technique also from the canonical fromalism.

description: Το θέμα αυτής της εργασίας ήταν οι μέθοδοι αυτόματης περίληψης κειμένου με τη βοήθεια νευρωνικών δικτύων και πώς αυτές μπορούν να εφαρμοστούν σε επιστημονικά συγγράμματα. Η ανάπτυξη αξιόπιστων μεθόδων αυτόματης περίληψης είναι ένα πρόβλημα που τα τελευταία χρόνια έχει μελετηθεί εκτενώς στην βιβλιογραφία. Στο πρόβλημα της αυτόματης περίληψης κειμένων επιδιώκουμε να κατασκευάσουμε με αυτόματο τρόπο ένα σύντομο κείμενο, πολύ συντομότερο από το πρωτότυπο που όμως να περιλαμβάνει με ακρίβεια τα βασικά στοιχεία που περιγράφονται στο αρχικό κείμενο. Το πρόβλημα αυτό είναι σημαντικό απο πολλές απόψεις. Πρώτον, η αναπαράσταση ενός συγγράμματος με μια σύντομη περίληψη μπορεί να βελτιώσει σημαντικά την επίδοση μηχανών αναζήτησης και συστημάτων ανάκλησης πληροφορίας. Δεύτερον, μπορούν να διευκολύνουν έναν αναγνώστη να βρεί εύκολα ποιά συγγράμματα είναι σχετικά με τα ενδιαφέροντά του και ποιά όχι. Τέλος, θα ήταν εξαιρετικά χρήσιμο για έναν συγγραφέα που μόλις ολοκλήρωσε το άρθρο του να μπορεί να δεί μια αυτόματη περίληψη που στη συνέχεια μπορεί να τροποποιηθεί ώστε να δημοσιευτεί σαν περίληψη του άρθρου. Έχει αναπτυχθεί ένας αριθμός από μεθόδους που βασίζονται στα νευρωνικά δίκτυα, οι οποίες πετυχαίνουν καλά αποτελέσματα ειδικά όταν πρόκειται για σύντομα κείμενα. H πλειοψηφία αυτών των μεθόδων έχει εστιάσει σε σύντομα κείμανα, κυρίως άρθρα εφημερίδων και προσπαθούν να κατασκευάσουν μια περίληψη μερικών προτάσεων. Αντιθέτως, τα επιστημονικά συγγράμματα είναι αρκετά εκτενή και η περίληψη τους είναι αδύνατον να γίνει μέσα σε μερικές προτάσεις. Είναι κατανοητό ότι το συγκεκριμένο πρόβλημα είναι αρκετά πιο δύσκολο από την περίληψη άρθρων από εφημερίδες. Σε αυτή την εργασία μελετήσαμε πώς διάφορες σύγχρονες μέθοδοι πετυχαίνουν καλά αποτελέσματα σε σύντομα άρθρα θα μπορούσαν να εφαρμοστούν σε επιστημονικά συγγράμματα
description: We explore the problem of automatic summarization of academic publications with different state-of-the-art summarization methods that are based on recurrent neural networks. This is a particularly important yet challenging problem with many applications in the academic research. We created a PMC-SA, a novel dataset of academic articles from the biomedical domain that have structured abstracts and is suitable for the training and evaluation of neural network summarization models. We also show that by exploiting the structured abstracts of academic articles, we can train superior summarization models that not only produce readable and structured abstracts, but also manage to maintain a lot of the key concepts described in the article. This method can be used with any summarization model and improves the the performance of all models on the new new PMC-SA dataset by as much as 4 points in terms of ROUGE f1 score
Effects of cold dark matter decoupling and pair annihilation on cosmological perturbations

description: Weakly interacting massive particles are part of the lepton-photon plasma in the early universe until kinetic decoupling, after which time the particles behave like a collisionless gas with nonzero temperature. The Boltzmann equation for WIMP-lepton collisions is reduced to a Fokker-Planck equation for the evolution of the WIMP distribution including scalar density perturbations. This equation and the Einstein and fluid equations for the plasma are solved numerically including the acoustic oscillations of the plasma before and during kinetic decoupling, the frictional damping occurring during kinetic decoupling, and the free-streaming damping occurring afterwards and throughout the radiation-dominated era. An excellent approximation reduces the solution to quadratures for the cold dark matter density and velocity perturbations. The subsequent evolution is followed through electron pair annihilation and the radiation-matter transition; analytic solutions are provided for both large and small scales. For a 100 GeV WIMP with bino-type interactions, kinetic decoupling occurs at a temperature $T_d=23$ MeV. The transfer function in the matter-dominated era leads to an abundance of small cold dark matter halos; with a smooth window function the Press-Schechter mass distribution is $dn/d\ln M\propto M^{-1/3}$ for $M<10^{-4} (T_d/$10 MeV)$^{-3}$ M$_\odot$.

description: Der Blick in die Zukunft fällt heute deshalb so schwer, weil sich die Veränderungen unseres Lebens in immer kürzeren Zeiträumen vollziehen. Dies gilt auch im Hinblick auf Institutionen wie Öffentliche Bibliotheken, die fachlich, personell und finanziell auf diese schnelllebigen Veränderungsprozesse reagieren müssen. Dennoch lässt sich anhand von drei Schlüsselkompetenzen, die in der Gegenwart bereits wahrgenommen werden, aufzeigen, welche Rolle Öffentliche Bibliotheken als „Orte der demokratischen Teilhabe“ im Jahr 2030 spielen können und sollten: aktive Vermittlung von Lesekompetenz, fundierte Erschließung und Bereitstellung von politisch und gesellschaftlich relevanten Informationen, offensive Etablierung als Begegnungs-, Kommunikations- und Aktionsorte. Die praktische Ausfüllung dieser drei Kompetenzbereiche setzt allerdings auch ein Personal voraus, das offen und flexibel auf die Anforderungen der Menschen reagiert, die Bibliotheken als „Dritten Ort“ in ihrem Leben nutzen wollen.
