description: We give an overview of different types of entanglement that can be generated in experiments, as well as of various protocols that can be used to verify or quantify entanglement. We propose several criteria that, we argue, should be applied to experimental entanglement verification procedures. Explicit examples demonstrate that not following these criteria will tend to result in overestimating the amount of entanglement generated in an experiment or in infering entanglement when there is none. We distinguish protocols meant to refute or eliminate hidden-variable models from those meant to verify entanglement.

Animal-Shaped Masks in Sixteenth-Century Italian Sculpture, Architecture and Armour

Year: 2024

description: In sixteenth-century Florence a variety of sculptural or architectural ornament was developed in the shape of animal masks, often featuring several animals or parts of different animals in one object, and the presence of eyes half hidden behind the surface mask. Michelangelo’s New Sacristy is a main locus for the development of these ornaments, but they soon spread over the city. Although sixteenth-century viewers called them “grotesques”, they differ from the two-dimensional variety inspired by the Domus Aurea because they consistently use strange, hybrid animal features that are not part of the repertoire of mythological hybrid beasts such as griffins, commonly used in grotesques inspired by the Roman tradition. They also stand out because they share these animal features with parade and tournament armour of the same period. Their formal characteristics, as well as their similarity to the ornament of contemporary parade armour, little studied until now, raises many questions about their origins, meaning, circumstances of creation and use, and possible impact. These ornaments also share many formal and compositional features with the masks made in the nineteenth and twentieth centuries by the peoples of the Northwest Coast of North America. They share a duplication or triplication of animal shapes, the presence of eyes behind the mask, incrustation and other graphical patterns, and a particular patterning, or spreading, of animal features across the object they cover. The central question this article seeks to address is therefore: is it possible to develop an approach to these masks, both Italian and North American, that can suggest a common ground, in form, function, impact, or sets of beliefs that drove their creation and use? The analysis of Northwestern Coast mask design by Franz Boas, Claude Lévi-Strauss and Philippe Descola will serve, first, as an instrument to better understand the composition of sixteenth-century animal-shaped masks, because they make the viewer aware of aspects of their design that remain under the radar in traditional stylistic or iconographical interpretation. Second, the similarities between these two groups of artefacts will point to shared sets of beliefs in nature as a source of endless transformation, and in the fundamental kinship of humans and animals.

description: We present a numerical and experimental study of the impact of phase errors on the performance of large, high-resolution Arrayed Waveguide Gratings (AWG) for applications in astronomy. We use a scalar diffraction model to study the transmission spectrum of an AWG under random variations of the optical waveguide lengths. We simulate phase error correction by numerically trimming the lengths of the optical waveguides to the nearest integer multiple of the central wavelength. The optical length error distribution of a custom-fabricated silica AWG is measured using frequency-domain interferometry and Monte-Carlo fitting of interferogram intensities. In the end, we give an estimate for the phase-error limited size of a waveguide array manufactured using state-of-the-art technology. We show that post-processing eliminates phase errors as a performance limiting factor for astronomical spectroscopy in the H-band.

Όλες οι παράμετροι της τεχνικής ατομικής φασματοσκοπίας με συζευγμένο πλάσμα βελτιστοποιήθηκαν ενώ επίσης προσδιορίστηκε η μέγιστη μάζα του δείγματος προς πέψη και ο συνολικός χρόνος της πέψης. Τέλος όλες οι πέψεις έγιναν με τη χρήση μόνο HNO3. Η προτεινόμενη μέθοδος είναι ικανή να εφαρμοστεί για τον ταυτόχρονο προσδιορισμό των Al, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, In, Mg, Mn, Ni, Pb, Tl, και Zn σε δείγματα ελαιολάδου με όρια ανίχνευσης 0,07 – 0,5 μg/g ενώ επίσης προσδιορίστηκαν η επαναληψιμότητα και η ανάκτηση της μεθόδου. Η μέθοδος εφαρμόστηκε σε 47 δείγματα που προέρχονταν από τα Ιόνια νησιά και η ανάλυση των δειγμάτων έδειξε ότι οι συγκεντρώσεις των τοξικών μετάλλων ήταν κάτω από τα επιτρεπτά όρια από τους κανονισμούς της Ευρωπαϊκής Ένωσης.
description: A fast technique was develop for the determination of metals in oil samples with inductively coupled plasma atomic emission spectrometry (ICP-AES) and a microwave assisted decomposition of the olive oil in closed vessels using only nitric acid. Microwave digestion sample mass as well as digestion time have been optimised, also instrumental parameters have been optimised with the presence of olive oil matrix. The proposed ICP-AES method permits the determination of Al, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, In, Mg, Mn, Ni, Pb, Tl, and Zn in olive oils and the low achievable LODs enable the determination even very low concentrations of most elements of interest. The proposed method was applied to the analysis of 47 olive oil sample from western Greece (Ionian islands) and the concentration of metal were below of the EU regulations limits.
Michael Snijders's Copious Copies and the Mechanisms of Print

Publisher: name: 21: Inquiries into Art, History, and the Visual
Year: 2024

description: Between around 1630 and 1640, the little-studied printmaker Michael Snijders engraved an idiosyncratic series likely consisting of at least twenty-two prints. Approximating the logics of both drawing manual and sketchbook, the series brings together head studies, limbs, flora, fauna, antique costume, and fantastical creatures. Almost every one of these myriad motifs is copied from another source and staged – over the course of multiple, radically altered states – to produce a delightful play on the entwined concepts of copy and copiousness for artists and increasingly attentive connoisseurs. As this essay argues, Snijders’s series thus amounts to an intensive commentary on the mechanisms of print as a medium and, through this, on the history of early modern art and the status of the “copy” within it.

Στόχος της παρούσας εργασίας είναι να μελετήσει το θέμα της συνεργασίας σχολείου οικογένειας σε διαπολιτισμικά σχολεία. Η έρευνα προσπάθησε να φέρει στην επιφάνεια πληροφορίες για το τι πιστεύουν οι εκπαιδευτικοί για τη σχέση αυτή( τη σπουδαιότητα της συνεργασίας, τη συχνότητα και τους τρόπους επικοινωνίας, το αντικείμενο και τα χαρακτηριστικά της συνεργασίας καθώς και τα εμπόδια που δυσχεραίνουν τη συνεργασία σχολείου οικογένειας). Η συλλογή των δεδομένων πραγματοποιήθηκε κατά τη διάρκεια του σχολικού έτους 2008-09 και πιο συγκεκριμένα τους μήνες του Απριλίου, Μαΐου και του Ιουνίου, μέσω ημιδομημένων συνεντεύξεων δώδεκα εκπαιδευτικών που εργάζονται σε τρία Διαπολιτισμικά σχολεία. Τα ευρήματα της έρευνας ανέδειξαν ανάμεσα στα άλλα ότι οι εκπαιδευτικοί επιθυμούν τη συμμετοχή και συνεργασία των γονέων, η συνεργασία περιορίζεται στην ενημέρωση των γονέων και πως οι εκπαιδευτικοί δεν αντιμετωπίζουν τους γονείς ως ισότιμους εταίρους στην εκπαιδευτική διαδικασία. Η πλειοψηφία των εκπαιδευτικών πιστεύει ότι οι γονείς μειονοτικών ομάδων (ειδικά οι ρομά γονείς) δεν ενδιαφέρονται για την εκπαίδευση των παιδιών τους.
description: Both family and school want young people to succeed in their academic, personal and social lives. The purpose of this dissertation is to explore the issue of school-family collaboration. A qualitative research was used to determine the views of teachers who work in intercultural elementary schools regarding the School- Family partnership (the importance of school-home collaboration, the frequency and the ways of the communication, the content of the collaboration and the barriers to this collaboration). Data were collected through semi-structured interviews for the period from April to June 2009. Twelve educators in three intercultural public schools were studied. The findings revealed, amongst others, that all of the educators would like parents to become more involved. The majority of educators believe that parents should just be kept informed. The educators see the parents as agents than as equal partners in the educational process. The majority of teachers believe that minority parents (roma parents) take too little interest in their children's education.

description: In recent years, a great deal of emphasis has been placed on achieving the diffraction limit with large aperture telescopes. For a well matched focal-plane instrument, the diffraction limit provides the highest possible angular resolution and sensitivity per pixel. But it offers another key advantage as we now show. Conventionally, as the telescope aperture D grows, the instrument size grows in proportion to D, and cost increases as D^2 or faster. However, an instrument that operates at the diffraction limit can break the trend of spiralling costs. In traditional instruments, the light must pass through a succession of large lenses, mirrors and gratings, making it difficult to conserve the integrity of such as small psf. An alternative approach, as we now show, is to couple the diffraction limited beam directly into an integrated photonic spectrograph operating in low-order modes.

description: This article analyses both well-known and unfamiliar paintings, illustrations and mosaics depicting the Ukrainian Donbas region by the Socialist Realist artist Aleksandr Deineka (1899–1969). Having been received, because of his modernism, rather sympathetically in the West, Deineka produced an array of Donbas images that can be employed as a starting point for analysing Soviet imperial ideology in art. The case of Deineka shows the extent of Soviet imperial and colonial strategies in regard to nations that were subjected to Moscow’s rule, and that even Deineka, who is considered as a critical Socialist Realist, was one of the most powerful ideologues of Soviet colonial imperialism.

description: The periodic Lorentz gas with external field and iso-kinetic thermostat is equivalent, by conformal transformation, to a billiard with expanding phase-space and slightly distorted scatterers, for which the trajectories are straight lines. A further time rescaling allows to keep the speed constant in that new geometry. In the hyperbolic regime, the stationary state of this billiard is characterized by a phase-space contraction rate, equal to that of the iso-kinetic Lorentz gas. In contrast to the iso-kinetic Lorentz gas where phase-space contraction occurs in the bulk, the phase-space contraction rate here takes place at the periodic boundaries.

description: Personalized community detection aims to generate communities associated with user need on graphs, which benefits many downstream tasks such as node recommendation and link prediction for users, etc. It is of great importance but lack of enough attention in previous studies which are on topics of user-independent, semi-supervised, or top-K user-centric community detection. Meanwhile, most of their models are time consuming due to the complex graph structure. Different from these topics, personalized community detection requires to provide higher-resolution partition on nodes that are more relevant to user need while coarser manner partition on the remaining less relevant nodes. In this paper, to solve this task in an efficient way, we propose a genetic model including an offline and an online step. In the offline step, the user-independent community structure is encoded as a binary tree. And subsequently an online genetic pruning step is applied to partition the tree into communities. To accelerate the speed, we also deploy a distributed version of our model to run under parallel environment. Extensive experiments on multiple datasets show that our model outperforms the state-of-arts with significantly reduced running time.

description: We give a criterion on pairs $(G,S)$ - where $G$ is a virtually $s$-step nilpotent group and $S$ is a finite generating set - saying whether the geodesic growth is exponential or strictly sub-exponential. Whenever $s=1,2$, this goes further and we prove the geodesic growth is either exponential or polynomial. For $s\ge 3$ however, intermediate growth is possible. We provide an example of virtually $3$-step nilpotent group for which $γ_{\mathrm{geod}}(n) \asymp \exp\!\big(n^{3/5}\cdot \log(n)\big)$. This is the first known example of group with intermediate geodesic growth. Along the way, we prove results on the geometry of virtually nilpotent groups, including asymptotics with error terms for their volume growth.

Effects of chronic stress and diabetes on antioxidant status and myocardial susceptibility to ischemia/reperfusion injury
Creators: name: Toleikis, Philip
Publisher: name: University of British Columbia
Year: 2009

description: Diabetes and psychological stress can both be described as states in which the actions of glucocorticoids and catecholamines predominate over those of insulin. Stress has a permissive, albeit poorly defined, effect on the development of myocardial infarction and atherosclerosis, which are major complications of the diabetic state; reactive oxygen radicals have been implicated in both conditions. Therefore, the effects of chronic-intermittent variable restraint stress on antioxidant status and myocardial susceptibility to ischemial/reperfusion injury in control, and streptozotocin diabetic rats were investigated. As an initial approach, the influence of chemical and/or surgical sympathectomy on the, antioxidant status of various tissues was investigated in non-diabetic rats. The effects of acute and chronic stress in diabetic and non-diabetic rats on levels of glucose, corticosterone and catecholamines measured from blood collected through in-dwelling catheters were compared. Antioxidant status of blood and tissues from normal and short- and long-term diabetic rats exposed to stress was assessed in terms of activities of antioxidant enzymes (catalase, superoxide dismutase, g lutathione peroxidase and glutathione reductase), non-enzymatic antioxidants (glutathione, ascorbate and tocopherol) and in vitro peroxide challenge. To determine whether stress-induced alteration in antioxidant capacity in diabetes was a result of the associated hyperlipidemia, non-diabetic rats with diet-induced hyperlipidemia were subjected to stress and resultant effects on plasma lipid profiles and antioxidant components and functional status examined. Finally, the effects of stress on myocardial susceptibility to ischemial/reperfusion injury were investigated in terms of myocardial function and antioxidant status. Studies involving sympathectomy suggested differential actions of adrenaline and noradrenaline on antioxidant components. The corticosterone and catecholamine responses to acute and chronic stress are modified by diabetes. While antioxidant systems are normally resistant to stress, their susceptibility to stress-induced modification increases in diabetes, a pathological condition associated with increased oxidative challenge. Stress-induced changes in plasma lipids and antioxidant components cannot be solely ascribed to the associated hyperlipidemia in diabetes. While some diabetes-associated antioxidant alterations occurred regardless of its duration, other differences related to the long term effects of the disease. The consequences of stress on diabetes-associated antioxidant changes and myocardial susceptibility to ischemial/reperfusion injury were to some extent modified by the duration of diabetes.

description: Having a comprehensive, high-quality dataset of road sign annotation is critical to the success of AI-based Road Sign Recognition (RSR) systems. In practice, annotators often face difficulties in learning road sign systems of different countries; hence, the tasks are often time-consuming and produce poor results. We propose a novel approach using knowledge graphs and a machine learning algorithm - variational prototyping-encoder (VPE) - to assist human annotators in classifying road signs effectively. Annotators can query the Road Sign Knowledge Graph using visual attributes and receive closest matching candidates suggested by the VPE model. The VPE model uses the candidates from the knowledge graph and a real sign image patch as inputs. We show that our knowledge graph approach can reduce sign search space by 98.9%. Furthermore, with VPE, our system can propose the correct single candidate for 75% of signs in the tested datasets, eliminating the human search effort entirely in those cases.

description: We present a generalization of the often-used Crank-Nicolson (CN) method of obtaining numerical solutions of the time-dependent Schrödinger equation. The generalization yields numerical solutions accurate to order $(Δx)^{2r-1}$ in space and $(Δt)^{2M}$ in time for any positive integers $r$ and $M$, while CN employ $r=M=1$. We note dramatic improvement in the attainable precision (circa 10 or greater orders of magnitude) along with several orders of magnitude reduction of computational time. The improved method is shown to lead to feasible studies of coherent-state oscillations with additional short-range interactions, wavepacket scattering, and long-time studies of decaying systems.

description: The spectrum of the spherically symmetric alpha-2 dynamo is studied in the case of idealized boundary conditions. Starting from the exact analytical solutions of models with constant alpha-profiles a perturbation theory and a Galerkin technique are developed in a Krein-space approach. With the help of these tools a very pronounced alpha-resonance pattern is found in the deformations of the spectral mesh as well as in the unfolding of the diabolical points located at the nodes of this mesh. Non-oscillatory as well as oscillatory dynamo regimes are obtained. A Fourier component based estimation technique is developed for obtaining the critical alpha-profiles at which the eigenvalues enter the right spectral half-plane with non-vanishing imaginary components (at which overcritical oscillatory dynamo regimes form). Finally, Frechet derivative (gradient) based methods are developed, suitable for further numerical investigations of Krein-space related setups like MHD alpha-2-dynamos or models of PT-symmetric quantum mechanics.

description: We show that the main features of the cuprates superconductors phase diagram can be derived considering the disorder as a key property of these materials. Our basic point is that the high pseudogap line is an onset of phase separation which generates compounds made up of regions with distinct doping levels. We calculate how this continuous temperature dependent phase separation process occurs in high critical temperature superconductors (HTSC) using the Cahn-Hilliard approach, originally applied to study alloys. Since the level of phase separation varies for different cuprates, it is possible that different systems with average doping level pm exhibit different degrees of charge and spin segregation. Calculations on inhomogeneous charge distributions in form of stripes in finite clusters performed by the Bogoliubov-deGennes superconducting approach yield good agreement to the pseudogap temperature T*(pm), the onset of local pairing amplitudes with phase locked and concomitantly, how they develop at low temperatures into the superconducting phase at Tc(pm) by percolation.

Knowledge representation and reasoning

description: In this paper we will examine and represents the difficulties about ramification problem. Many proposals can be found with standard solutions in related research works emphasizing on reasoning about actions, but they are insufficient in spatial-temporal databases (STDB) because they can’t capture integrity constrains. Our contribution to the ramification problem is to provide a solution based on situation calculus. This solution will connect the theoretical part with the practical one through a tool called “Anasa”. This tool was created to produce a friendly User Interface in C# in order to graphically project the problem in specific time period of an XML file to address the ramification problem.

Σε σχετικές εργασίες πάνω στην περιοχή μπορούμε να βρούμε αρκετές λύσεις που δίνουν έμφαση στην συλλογιστική των ενεργειών, αλλά είναι ανεπαρκείς σε χωροχρονικές βάσεις δεδομένων (STDB) διότι δεν μπορούν να συμπεριλάβουν την ιδιότητα των κανόνων ακεραιότητας. Η δική μας συνεισφορά στο πρόβλημα αυτών των επιπτώσεων είναι η παρουσίαση μιας λύσης που βασίζεται στην λογική των καταστάσεων (situation calculus). Αυτή η λύση θα συνδυάσει το θεωρητικό κομμάτι με το πρακτικό, μέσω ενός εργαλείου που δημιουργήσαμε για τις ανάγκες της έρευνας μας το οποίο ονομάζεται “Ανάσα”. Αυτό το εργαλείο δημιουργήθηκε με σκοπό να παρέχει ένα εύκολο στην χρήση περιβάλλον χρήστη φτιαγμένο σε C# με σκοπό να παρέχει μια γραφική απεικόνιση του προβλήματος σε κάποια συγκεκριμένη χρονική στιγμή ενός XML αρχείου για να αντιμετωπίσουμε το πρόβλημα των επιπτώσεων.

description: In the quest to understand high-temperature superconductivity in copper oxides, a vigorous debate has been focused on the pseudogap - a partial gap that opens over portions of the Fermi surface in the 'normal' state above the bulk critical temperature ($T_{c}$). The pseudogap has been attributed to precursor superconductivity, to the existence of preformed pairs, or to competing orders such as charge-density waves. A direct determination of the charge of carriers as a function of temperature and bias could help resolve among these alternatives. Here, we report measurements of the shot noise of tunneling current in high-quality La$_{2-x}$Sr$_{x}$CuO$_{4}$/La$_{2}$CuO$_{4}$/La$_{2-x}$Sr$_{x}$CuO$_{4}$ (LSCO/LCO/LSCO) heterostructures fabricated using atomic-layer-by-layer molecular beam epitaxy, for several doping levels. The data delineate three distinct regions in the bias voltage-temperature ($V-T$) space. Well outside the superconducting gap region, the shot noise agrees quantitatively with independent tunneling of charge-e carriers. Deep within the gap, shot noise is greatly enhanced, reminiscent of multiple Andreev reflections. Starting above $T_{c}$ and extending to biases much larger than the gap, there is a broad region in which the noise substantially exceeds the expectations of single-charge tunneling, indicating pairing of carriers. Pairs are detectable deep into the pseudogap region of temperature and bias.

‘Arrayed as if for War’: Tactical innovation and technological change in Late Medieval and Early Modern rebellions (1381-1554)

description: Rebellion in Late-Medieval and Early Modern England has generally been regarded as posing little military threat to the realm, with conflicts between loyalists and insurgents commonly dismissed as one-sided routs of hopelessly outclassed, poorly armed peasants. More detailed investigation, however, suggests that rebels could be tough and resourceful opponents, with access to effective weaponry, training, and leadership, and that government forces faced stiff resistance when supressing popular insurgencies. By exploring the resources available to uprisings ranging from the Peasants’ Revolt to Wyatt’s Rebellion, this article will also assess their implications for England’s uncertain position within the European military context.

description: We report the discovery with XMM-Newton of quasiperiodic variability in the 0.2 - 10 keV X-ray flux from the ultraluminous X-ray source NGC 5408 X-1. The average power spectrum of all EPIC-pn data reveals a strong 20 mHz QPO with an average amplitude (rms) of 9%, and a coherence of Q~6. In a 33 ksec time interval when the 20 mHz QPO is strongest we also find evidence for a 2nd QPO peak at 15 mHz. This is the first indication for a close pair of QPOs in a ULX source. Interestingly, the frequency ratio of this QPO pair is inconsistent with 3:2 at the 3sigma level, but is consistent with a 4:3 ratio. A powerlaw noise component with slope near 1.5 is also present below 0.1 Hz with evidence for a break to a flatter slope at about 3 mHz. The source shows substantial broadband variability, with a total amplitude (rms) of about 30% in the 0.1 - 100 mHz frequency band, and there is strong energy dependence to the variability. We discuss the implications of these findings in the context of models for ULXs, and their implications for the object's mass.

description: Καθημερινά, τόσο τα άτομα στην προσωπική τους ζωή, όσο και οι μάνατζερ στις επιχειρήσεις και τους οργανισμούς, που διευθύνουν, καλούνται να πάρουν αποφάσεις. Από την ορθολογικότητα των αποφάσεών τους κρίνεται η επιβίωση της εταιρείας τους. Η διαδικασία λήψης απόφασης, λόγω της πολυπλοκότητας των προβλημάτων απόφασης, του αυξημένου όγκου των δεδομένων/πληροφοριών και της εξέλιξης της τεχνολογίας, απαιτεί την υποστήριξη ενός συστήματος λήψης απόφασης. Τα συστήματα λήψης απόφασης έχουν πλέον ενσωματωθεί στη λειτουργία πολλών επιχειρήσεων και υπηρεσιών. Παρέχουν σημαντική βοήθεια στους χρήστες τους, λαμβάνοντας αποφάσεις ζωτικής σημασίας για τη βιωσιμότητα της επιχείρησης/υπηρεσίας, όπως η απόφαση αξιολόγησης και επιλογής προσωπικού.

description: Everyday, managers have to make decisions. The sustentation of their firms depends on the soberness of these decisions. For that reason, “Decision Making” needs a Decision Support System, in order to deal with the complexity of the decision problems, the increased volume of data and the development of technology. Nowadays, many companies and organizations use Decision Support Systems (DSS) in their operations. This work examines the key features and value/use of DSS and presents an Analytical Hierarchy Process (AHP) Model for Employee Evaluation and Selection. The decision problem solved with the software Expert Choice. In the first part of the project, the Theoretical Framework is presented, where the definition, meaning and application of DSS is mentioned. Next, the operation and use of Expert Choice is represented with the analysis of the Multicriteria Method of AHP, which is the method that Expert Choice uses. In the second part of the project, the method of AHP is implemented on a real employee evaluation and selection problem of a Greek internal revenue service.
Negative radiation pressure exerted on kinks

description: The interaction of a kink and a monochromatic plane wave in one dimensional scalar field theories is studied. It is shown that in a large class of models the radiation pressure exerted on the kink is negative, i.e. the kink is {\sl pulled} towards the source of the radiation. This effect has been observed by numerical simulations in the $ϕ^4$ model, and it is explained by a perturbative calculation assuming that the amplitude of the incoming wave is small. Quite importantly the effect is shown to be robust against small perturbations of the $ϕ^4$ model. In the sine-Gordon (sG) model the time averaged radiation pressure acting on the kink turns out to be zero. The results of the perturbative computations in the sG model are shown to be in full agreement with an analytical solution corresponding to the superposition of a sG kink with a cnoidal wave. It is also demonstrated that the acceleration of the kink satisfies Newton's law.

description: In this paper, we discuss some numerical realizations of Shannon's sampling theorem. First we show the poor convergence of classical Shannon sampling sums by presenting sharp upper and lower bounds of the norm of the Shannon sampling operator. In addition, it is known that in the presence of noise in the samples of a bandlimited function, the convergence of Shannon sampling series may even break down completely. To overcome these drawbacks, one can use oversampling and regularization with a convenient window function. Such a window function can be chosen either in frequency domain or in time domain. We especially put emphasis on the comparison of these two approaches in terms of error decay rates. It turns out that the best numerical results are obtained by oversampling and regularization in time domain using a sinh-type window function or a continuous Kaiser-Bessel window function, which results in an interpolating approximation with localized sampling. Several numerical experiments illustrate the theoretical results.
