description: The lattice spin model with $Q$--component discrete spin variables restricted to have orientations orthogonal to the faces of $Q$-dimensional hypercube is considered on the Bethe lattice, the recursive graph which contains no cycles. The partition function of the model with dipole--dipole and quadrupole--quadrupole interaction for arbitrary planar graph is presented in terms of double graph expansions. The latter is calculated exactly in case of trees. The system of two recurrent relations which allows to calculate all thermodynamic characteristics of the model is obtained. The correspondence between thermodynamic phases and different types of fixed points of the RR is established. Using the technique of simple iterations the plots of the zero field magnetization and quadrupolar moment are obtained. Analyzing the regions of stability of different types of fixed points of the system of recurrent relations the phase diagrams of the model are plotted. For $Q \leq 2$ the phase diagram of the model is found to have three tricritical points, whereas for $Q> 2$ there are one triple and one tricritical points.

description: Cen X-3 is a compact high mass X-ray binary likely powered by Roche lobe overflow. We present a phase-resolved X-ray spectral and timing analysis of two pointed XMM-Newton observations. The first one took place during a normal state of the source, when it has a luminosity $L_{\rm X}\sim 10^{36}$ erg s$^{-1}$. This observation covered orbital phases $ϕ= 0.00-0.37$, i.e. the egress from the eclipse. The egress lightcurve is highly structured, showing distinctive intervals. We argue that different intervals correspond to the emergence of different emitting structures. The lightcurve analysis enables us to estimate the size of such structures around the compact star, the most conspicuous of which has a size $\sim 0.3R_{*}$, of the order of the Roche lobe radius. During the egress, the equivalent width of Fe emission lines, from highly ionized species, decreases as the X-ray continuum grows. On the other hand, the equivalent width of the Fe K$α$ line, from near neutral Fe, strengthens. This line is likely formed due to the X-ray illumination of the accretion stream. The second observation was taken when the source was 10 times X-ray brighter and covered the orbital phases $ϕ= 0.36-0.80$. The X-ray lightcurve in the high state shows dips. These dips are not caused by absorption but can be due to instabilities in the accretion stream. The typical dip duration, of about 1000~s, is much longer than the timescale attributed to the accretion of the clumpy stellar wind of the massive donor star, but is similar to the viscous timescale at the inner radius of the accretion disk.

description: We use simulations to study the growth of a pseudobulge in an isolated thin exponential stellar disc embedded in a static spherical halo. We observe a transition from later to earlier morphological types and an increase in bar prominence for higher disc-to-halo mass ratios, for lower disc-to-halo size ratios, and for lower halo concentrations. We compute bulge-to-total stellar mass ratios $B/T$ by fitting a two-component Sérsic-exponential surface-density distribution. The final $B/T$ is strongly related to the disc's fractional contribution $f_{\rm d}$ to the total gravitational acceleration at the optical radius. The formula $B/T=0.5\,f_{\rm }^{1.8}$ fits the simulations to an accuracy of $30\%$, is consistent with observational measurements of B/T and f_d as a function of luminosity, and reproduces the observed relation between $B/T$ and stellar mass when incorporated into the GalICS~2.0 semi-analytic model of galaxy formation.

description: We develop a three-party quantum secret sharing protocol based on arbitrary dimensional quantum states. In contrast to the previous quantum secret sharing protocols, the sender can always control the state, just using local operations, for adjusting the correlation of measurement directions of three parties and thus there is no waste of resource due to the discord between the directions. Moreover, our protocol contains the hidden value which enables the sender to leak no information of secret key to the dishonest receiver until the last steps of the procedure.

description: Η κλιματική αλλαγή είναι ένα παγκόσμιο φαινόμενο, το οποίο συνδέεται στενά με την ενέργεια που καταναλώνεται στις πόλεις, εξαιτίας του υψηλού βαθμού συγκέντρωσης ανθρώπων και δραστηριοτήτων, καθιστώντας φλέγον το ζήτημα της Βιώσιμης Αστικής Ανάπτυξης. Σε παγκόσμιο και ευρωπαϊκό επίπεδο, τα τελευταία χρόνια λαμβάνουν χώρα συζητήσεις και συμφωνίες για τον περιορισμό των επιπτώσεων της ανθρώπινης δραστηριότητας στο περιβάλλον και τη μείωση των εκπομπών αερίων του θερμοκηπίου, κύριων υπεύθυνων για την κλιματική αλλαγή, την ώρα που η Ελλάδα από τη μεριά της δεν επιδεικνύει υψηλές επιδόσεις σε θέματα περιβάλλοντος.

description: Climate Change is a universal phenomenon, closely related to energy consumption within cities, due to high accumulation of people and activities, thus raising the issue of Sustainable Urban Development. Recently, numerous discussions and agreements have been taking place on a worldwide and European level, regarding the limitation of human activity environmental impacts, as well as the reduction of greenhouse gas emissions, to which climate change is attributed. Meanwhile, Greece does not exhibit satisfactory performance rates on environmental issues. In the modern urban theory, the question of the ideal urban form with regard to minimal energy consumption remains unanswered, but Energy Planning on a community level has been proven capable of offering holistic solutions, which contribute to the general socio-economic development of an area. City Planning for Sustainable Urban Development has also come up with several city models, some of which are the Low Carbon or Zero Carbon City, the Solar City, Sustainable Neighborhoods or Eco-neighborhoods, as well as communities that make use of Geothermal Phenomena. These models project themselves as answers to the issue of urban sustainability and initiate the discussion of Urban Energy issues and the Sustainable City of the Future.

description: Η παρούσα εργασία είναι μία απόπειρα μελέτης και εμβάθυνσης στο περιεχόμενο του πλαστού λόγου του Αίαντα στην ομώνυμη τραγωδία του Σοφοκλή (στ.646-692). Πρόκειται για ένα από τα πιο πολυσυζητημένα χωρία της αρχαίας ελληνικής γραμματείας που έχει προβληματίσει και διχάσει τους μελετητές. Αυτός ο υπέροχος, αινιγματικός και περίπλοκος λόγος που βρίθει αμφίσημων αναφορών βρίσκεται στην καρδιά του δράματος και θεωρείται μάλιστα το κλειδί για την κατανόηση όλου του έργου. Έτσι, κάθε στίχος αναλύεται και ερμηνεύεται ξεχωριστά σε μία προσπάθεια διασάφησης της διττής σημασίας του. Το ερώτημα που τίθεται είναι αν ο ήρωας εκφράζεται με ειλικρίνεια και είναι όντως διατεθειμένος να αλλάξει, ανακαλώντας την αρχική του απόφαση να θέσει τέλος στη ζωή του ή φορώντας το μανδύα της προσποίησης εκφράζει με οξύτατη διαύγεια τη σχέση του με το γύρω κόσμο, μέσα στον οποίο φαίνεται τελικά να μην έχει θέση. Στη δεύτερη περίπτωση ο χορός και η Τέκμησσα παραπλανώνται, ωστόσο ο Αίαντας αφήνει κάποιες σχισμές στα λεγόμενά του, ώστε να διακρίνεται η αλήθεια, η τελική κατάληξη, ο θάνατος. Ακολουθεί αναλυτική εκτίμηση των μελετητών για το αν ο ήρωας εξαπατά σκόπιμα ή μη τους δέκτες του για να καταλήξει η παρούσα μελέτη στον προσδιορισμό των ποικίλων λειτουργιών που επιτελεί, καθώς φαίνεται, ο συγκεκριμένος λόγος του Αίαντα.
description: This paper is an attempt to study thoroughly the dissembling speech of Ajax, part of the homonymous tragedy of Sophocles. The perplexing “Deception speech”(646-692) has been a controversial issue of much scholarship for many years. This is not surprising, since many believe that this magnificent, mysterious and complex speech, which is loaded with verbal ambiguity, is the key to understand the entire play. Its central position corresponds to its inner significance as the tragedy’s heart and the speech acts as the play’s major turning point. This is the reason why every single verse of this speech is been analyzed separately in this paper trying to give its two-edged meaning. The major question is whether the sophoclean hero speaks the truth and has really changed and abandoned the idea of committing suicide or he realizes and expresses wisely his position in a world where nothing is permanent and the moral code of the heroic code is meaningless. Ajax cannot accept such a world. In that case Tekmessa and the chorus are been deceived despite the fact that there are hints in the speech, which reveal the final truth, the hero’s death. Afterwards, the crucial question whether Ajax deceives deliberately or not his hearers is been answered by many scholars and the paper ends with the variety of functions that the deception speech has.

description: We present a simple lithographic method for fabrication of microresonator devices at the optical fiber surface. First, we undress the predetermined surface areas of a fiber segment from the polymer coating with a focused CO2 laser beam. Next, using the remaining coating as a mask, we etch the fiber in a hydrofluoric acid solution. Finally, we completely undress the fiber segment from coating to create a chain of silica bottle microresonators with nanoscale radius variation (SNAP microresonators). We demonstrate the developed method by fabrication of a chain of five 1 mm long and 30 nm high microresonators at the surface of a 125 micron diameter optical fiber and a single 0.5 mm long and 291 nm high microresonator at the surface of a 38 micron diameter fiber. As another application, we fabricate a rectangular 5 mm long SNAP microresonator at the surface of a 38 micron diameter fiber and investigate its performance as a miniature delay line. The propagation of a 100 ps pulse with 1 ns delay, 0.035c velocity, and negligible dispersion is demonstrated. In contrast to the previously developed approaches in SNAP technology, the developed method allows the introduction of much larger fiber radius variation ranging from nanoscale to microscale.

description: The Square Kilometer Array (SKA) would be the world's largest radio telescope with eventually over a square kilometer of collecting area. However, there are enormous challenges in its data processing. The using of modern distributed computing techniques to solve the problem of massive data processing in SKA is one of the most important challenges. In this study, basing on the Dask distribution computational framework, and taking the visibility function integral processing as an example, we adopt a multi-level parallelism method to implement distributed averaging over time and channel. Dask Array was used to implement super large matrix or arrays with supported parallelism. To maximize the usage of memory, we further exploit the data parallelism provided by Dask that intelligently distributes the computational load across a network of computer agents and has a built-in fault tolerance mechanism. The validity of the proposed pattern was also verified by using the Common Astronomy Software Application (CASA), wherein we analyze the smearing effects on images reconstructed from different resolution visibilities.

New estimations of the added mass and damping of two cylinders vibrating in a viscous fluid, from theoretical and numerical approaches

Publisher: name: arXiv
Year: 2021
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: This paper deals with the small oscillations of two circular cylinders immersed in a viscous stagnant fluid. A new theoretical approach based on an Helmholtz expansion and a bipolar coordinate system is presented to estimate the fluid forces acting on the two bodies. We show that these forces are linear combinations of the {\textcolor{black}{cylinder accelerations}} and velocities, through viscous fluid added coefficients. {\textcolor{black}{To assess the validity of this theory, we consider the case of two equal size cylinders, one of them being stationary while the other one is forced sinusoidally}}. The self-added mass and damping coefficients are shown to decrease with both the Stokes number and the separation distance. The cross-added mass and damping coefficients tend to increase with the Stokes number and the separation distance. Compared to the inviscid results, the effect of viscosity is to add a correction term which scales as $Sk^{-1/2}$. When the separation distance is sufficiently large, the two cylinders behave as if they were independent and the Stokes predictions for an isolated cylinder are recovered. Compared to previous works, the present theory offers a simple and flexible alternative for an easy determination of the fluid forces and related added coefficients. To our knowledge, this is also the first time that a numerical approach based on a penalization method is presented in the context of fluid-structure interactions for relatively small Stokes numbers, and successfully compared to theoretical predictions.

description: The gravitomagnetic field is the force exerted by a moving body on the basis of the intriguing interplay between geometry and dynamics which is the analog to the magnetic field of a moving charged body in electromagnetism. The existence of such a field has been demonstrated based on special relativity approach and also by special relativity plus the gravitational time dilation for two different cases, a moving infinite line and a uniformly moving point mass, respectively. We treat these two approaches when the applied cases are switched while appropriate key points are employed. Thus, we demonstrate that the strength of the resulted gravitomagnetic field in the latter approach is twice the former. Then, we also discuss the full linearized general relativity and show that it should give the same strength for gravitomagnetic field as the latter approach. Hence, through an exact analogy with the electrodynamic equations, we present an argument in order to indicate the best definition amongst those considered in this issue in the literature. Finally, we investigate the gravitomagnetic effects and consequences of different definitions on the geodesic equation including the second order approximation terms.

description: The analysis of gravitational wave data may require greater accuracy than is afforded by the adiabatic approximation to the trajectory of and field produced by a particle moving in curved spacetime. Higher accuracy is available with a two-timescale approach using as an expansion parameter the ratio of orbital time to radiation reaction time. To avoid apparent divergences at large distances, the details of the method are important, especially the choice of the foliation, the spacetime surfaces on which the orbital elements are taken to be constant. Here we apply the two-timescale approach to a simple linear model to demonstrate the details of the method. In particular we use it to show that a null foliation avoids large-distance divergences in the first-order post-adiabatic approximation, and we argue that this will be true more generally for a null foliation.

description: Underwater sites are a harsh environment for augmented reality applications. Obstacles that must be battled include poor visibility conditions, difficult navigation, and hard manipulation with devices under water. This chapter focuses on the problem of localizing a device under water using markers. It discusses various filters that enhance and improve images recorded under water, and their impact on marker-based tracking. It presents various combinations of 10 image improving algorithms and 4 marker detecting algorithms, and tests their performance in real situations. All solutions are designed to run real-time on mobile devices to provide a solid basis for augmented reality. Usability of this solution is evaluated on locations in Mediterranean Sea. It is shown that image improving algorithms with carefully chosen parameters can reduce the problems with visibility under water and improve the detection of markers. The best results are obtained with marker detecting algorithms that are specifically designed for underwater environments.

description: It is well known that the SOM algorithm achieves a clustering of data which can be interpreted as an extension of Principal Component Analysis, because of its topology-preserving property. But the SOM algorithm can only process real-valued data. In previous papers, we have proposed several methods based on the SOM algorithm to analyze categorical data, which is the case in survey data. In this paper, we present these methods in a unified manner. The first one (Kohonen Multiple Correspondence Analysis, KMCA) deals only with the modalities, while the two others (Kohonen Multiple Correspondence Analysis with individuals, KMCA\_ind, Kohonen algorithm on DISJonctive table, KDISJ) can take into account the individuals, and the modalities simultaneously.

Extending applications to the network

description: Network applications are applications capable of selecting, at run-time, portions of their code to execute at remote network locations. By executing remote code in a restricted environment and providing convenient communication mechanisms within the application, network applications enable the implementation of tasks that cannot be implemented using traditional techniques. Even existing applications can realize significant performance improvements and reduced resource consumption when redesigned as network applications. By examining several application domains, we expose specific desirable capabilities of a software infrastructure to support network applications. These capabilities entail a variety of interacting software development challenges for which we recommend solutions. The solutions are applied in the design and implementation of a network application infrastructure, Jay, based on the Java language. Jay meets most of the desired capabilities, particularly demonstrating a cohesive and expressive communication framework and an integrated yet simple security model. In all, network applications combine the best qualities of intelligent networks, active networks, and mobile agents into a single framework to provide a unique and effective development environment.

description: We suggest a new practical scheme for the direct detection of pure spin current by using the two-color Faraday rotation of optical quantum interference process (QUIP) in a semiconductor system. We demonstrate theoretically that the Faraday rotation of QUIP depends sensitively on the spin orientation and wave vector of the carriers, and can be tuned by the relative phase and the polarization direction of the $ω$ and $2ω$ laser beams. By adjusting these parameters, the magnitude and direction of the spin current can be detected.

How to use the Kohonen algorithm to simultaneously analyse individuals in a survey
Creators: name: Cottrell, Marie

Publisher: name: arXiv
Year: 2006
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: The Kohonen algorithm (SOM, Kohonen,1984, 1995) is a very powerful tool for data analysis. It was originally designed to model organized connections between some biological neural networks. It was also immediately considered as a very good algorithm to realize vectorial quantization, and at the same time pertinent classification, with nice properties for visualization. If the individuals are described by quantitative variables (ratios, frequencies, measurements, amounts, etc.), the straightforward application of the original algorithm leads to build code vectors and to associate to each of them the class of all the individuals which are more similar to this code-vector than to the others. But, in case of individuals described by categorical (qualitative) variables having a finite number of modalities (like in a survey), it is necessary to define a specific algorithm. In this paper, we present a new algorithm inspired by the SOM algorithm, which provides a simultaneous classification of the individuals and of their modalities.

description: The tri-bimaximal mixing is a good approximation for the present data of neutrino mixing angles. The deviation from the tri-bimaximal mixing is discussed numerically in the framework of the A4 model. Values of \tan^2θ_{12}, \sin^2 2θ_{23} and |U_{e3}| deviate from the tri-bimaximal mixing due to the corrections of the vacuum alignment of flavon fields. It is remarked that \sin^2 2θ_{23} deviates scarcely from 1 while \sin^2θ_{12} can deviate from 1/3 considerably and \sinθ_{13} could be near the present experimental upper bound. The CP violating measure J_{CP} and the effective Majorana neutrino mass m_{ee} are also discussed.

description: Already today, driver assistance systems help to make daily traffic more comfortable and safer. However, there are still situations that are quite rare but are hard to handle at the same time. In order to cope with these situations and to bridge the gap towards fully automated driving, it becomes necessary to not only collect enormous amounts of data but rather the right ones. This data can be used to develop and validate the systems through machine learning and simulation pipelines. Along this line this paper presents a fleet learning-based architecture that enables continuous improvements of systems predicting the movement of surrounding traffic participants. Moreover, the presented architecture is applied to a testing vehicle in order to prove the fundamental feasibility of the system. Finally, it is shown that the system collects meaningful data which are helpful to improve the underlying prediction systems.

Experimental study of the atmospheric neutrino backgrounds for proton decay to positron and neutral pion searches in water Cherenkov detectors

description: The atmospheric neutrino background for proton decay to positron and neutral pion in ring imaging water Cherenkov detectors is studied with an artificial accelerator neutrino beam for the first time. In total, about 314,000 neutrino events corresponding to about 10 megaton-years of atmospheric neutrino interactions were collected by a 1,000 ton water Cherenkov detector (KT). The KT charged-current single neutral pion production data are well reproduced by simulation programs of neutrino and secondary hadronic interactions used in the Super-Kamiokande (SK) proton decay search. The obtained proton to positron and neutral pion background rate by the KT data for SK from the atmospheric neutrinos whose energies are below 3 GeV is about two per megaton-year. This result is also relevant to possible future, megaton-scale water Cherenkov detectors.

Examining the psychometric properties of the Multidimensional experiential avoidance questionnaire in combustible cigarette smokers
Creators: name: Billingsley, Benjamin
Publisher: name: No Publisher Supplied
Year: 2023

description: Experiential avoidance, defined as an unwillingness to remain in contact with aversive internal experiences, has been linked to psychopathology. Smoking specific experiential avoidance, defined as an unwillingness to experience unpleasant smoking-related thoughts, feelings, and physical sensations, has been linked to cigarette smoking. However, what is unclear is whether higher levels of experiential avoidance are connected to greater levels of cigarette smoking. The purpose of this study was to validate a measure of experiential avoidance, the Multidimensional Experiential Avoidance Questionnaire (MEAQ), in a sample of individuals who smoke combustible cigarettes, and to investigate the relationship between nicotine dependence, cigarette smoking, and different facets of experiential avoidance. We ran a confirmatory factor analysis to verify the factor structure of the MEAQ and test measurement invariance across two samples. We conducted correlational analyses to test convergent validity, discriminant validity, and explore the relationship between combustible cigarette use and experiential avoidance. We used multivariate regression to see if general experiential avoidance predicted nicotine dependence beyond what was predicted by the avoidance and inflexibility scale (AIS), which is a measure of smoking specific experiential avoidance. We found that the sixty-two item MEAQ exhibited poor model fit, but a thirty item version of the MEAQ (MEAQ-30) demonstrated adequate model fit and met criteria for measurement invariance. The MEAQ-30 failed to meet our criteria for convergent validity and predictive validity, but met criteria for discriminant validity. We also failed to find a relationship between scores on the MEAQ-30 and level of tobacco dependence. Based on our findings, the MEAQ-30 is a more psychometrically sound measure of experiential avoidance than the full MEAQ. Future studies should investigate the convergent validity of the measure and examine its predictive validity in different samples. Finally, our study results indicate that the avoidance and inflexibility scale should be used to assess experiential avoidance in studies where smoking is a major outcome of interest, rather than the MEAQ-30.

description: Using the time-dependent theory of quantum mechanics, we investigate nuclear electric dipole responses. The time evolution of a wave function is explicitly calculated in the coordinate-space representation. The particle continuum is treated with the absorbing boundary condition. Calculated time-dependent quantities are transformed into those of familiar energy representation. We apply the method to a three-body model for 11Li and to the mean-field model for 22O, then discuss properties of E1 response.

Efficient multimedia retrieval using custom indexing methods
Creators: name: Steenburgh, Malcolm W.
Publisher: name: University of British Columbia
Year: 2009

description: One of the largest problems associated with content-based indexing of multi-media documents is the inefficiencies associated with the process. These inefficiencies are witnessed in a number of areas throughout the process, manifesting themselves in the form of high network bandwidth and processor requirements. The following piece of work examines two novel concepts which attempt to minimize these inefficiencies through the reduction in both bandwidth and processor requirements. Included in this work is a discussion related to the reduction of network bandwidth requirements. The discussion focuses around the network bandwidth currently associated with the development of indexing schemes. In order for developers to implement and test indexing schemes, they currently have to download and index all of the media to which the new scheme will be applied. In addition to this being time consuming and work intensive, the entire process results in large amounts of network traffic. The proposed solution to this problem is a software interface allowing developers to submit unique indexing schemes to remote servers for processing. Upon receipt, the remote server applies the scheme to an arbitrary subset of its indexed media, restricted only by a set of time constraints set by either the developer or server administrator. Within the time constraints, the server will apply the given scheme and return the best results to the user. The result is efficiencies that are orders of magnitude greater than possible through current methodology. The second concept discussed in the work focusses on the efficient application of known indexing schemes in query by example format queries. The algorithm makes use of the triangle inequality to reduce the number of media objects that actually have to be compared during query processing. In addition to a disussion of the aforementioned concepts, this work includes an examination of an actual implementation of the concepts using the Java programming language. The application shows the viability of both concepts, showing that they indeed reduce the inefficiency currently associated with multi-media indexing systems.

description: A nonlinear Schrodinger equation, that had been obtained within the context of the maximum uncertainty principle, has the form of a difference-differential equation and exhibits some interesting properties. Here we discuss that equation in the regime where the nonlinearity length scale is large compared to the deBroglie wavelength; just as in the perturbative regime, the equation again displays some universality. We also briefly discuss stationary solutions to a naturally induced discretisation of that equation.
