description: Objective: This study aims to establish a generalized transfer-learning framework for boosting the performance of steady-state visual evoked potential (SSVEP)-based brain-computer interfaces (BCIs) by leveraging cross-domain data transferring. Approach: We enhanced the state-of-the-art template-based SSVEP decoding through incorporating a least-squares transformation (LST)-based transfer learning to leverage calibration data across multiple domains (sessions, subjects, and EEG montages). Main results: Study results verified the efficacy of LST in obviating the variability of SSVEPs when transferring existing data across domains. Furthermore, the LST-based method achieved significantly higher SSVEP-decoding accuracy than the standard task-related component analysis (TRCA)-based method and the non-LST naive transfer-learning method. Significance: This study demonstrated the capability of the LST-based transfer learning to leverage existing data across subjects and/or devices with an in-depth investigation of its rationale and behavior in various circumstances. The proposed framework significantly improved the SSVEP decoding accuracy over the standard TRCA approach when calibration data are limited. Its performance in calibration reduction could facilitate plug-and-play SSVEP-based BCIs and further practical applications.

description: This work presents an application that generates real-time holograms to be displayed on a holographic optical tweezers setup; a technique that allows the manipulation of particles in the range from micrometres to nanometres. The software is written in Java, and uses random binary masks to generate the holograms. It allows customization of several parameters that are dependent on the experimental setup, such as the specific characteristics of the device displaying the hologram, or the presence of aberrations. We evaluate the software's performance and conclude that real-time interaction is achieved. We give our experimental results from manipulating 5 micron-diametre microspheres using the program.

description: We present Very Large Array (VLA) observations of H2O and OH masers, as well as radio continuum emission at 1.3 and 18 cm toward three sources previously cataloged as planetary nebulae (PNe) and in which single-dish detections of H2O masers have been reported: IRAS 17443-2949, IRAS 17580-3111, and IRAS 18061-2505. Our goal was to unambiguously confirm their nature as water-maser-emitting PNe, a class of objects of which only two bona-fide members were previously known. We detected and mapped H2O maser emission toward all three sources, while OH maser emission is detected in IRAS 17443-2949 and IRAS 17580-3111 as well as in other two objects within the observed fields: IRAS 17442-2942 (unknown nature) and IRAS 17579-3121 (also cataloged as a possible PN). We found radio continuum emission associated only with IRAS 18061-2505. Our results confirm IRAS 18061-2505 as the third known case of a PN associated with H2O maser emission. The three known water-maser-emitting PNe have clear bipolar morphologies, which suggests that water maser emission in these objects is related to non-spherical mass-loss episodes. We speculate that these bipolar PNe would have ``water-fountain'' Asymptotic Giant Branch (AGB) and post-AGB stars as their precursors. A note of caution is given for other objects that have been classified as OHPNe (objects with both OH maser and radio continuum emission, that could be extremely young PNe) based on single-dish observations, since interferometric data of both OH masers and continuum are necessary for a proper identification as members of this class.

description: The purpose of this thesis was to probe into civil law issues arising in the context of maritime oil transport in relation to the contractual and non- contractual liability that is being established in case of environmental pollution. The first part describes the national legal framework in respect of maritime oil transport through the analysis of the most significant points of charter and the carriage of goods by sea. In the second part, we examine the civil liability that is being established due to the environmental pollution in the field of these activities. In particular, we present and analyze the general provisions which are included in Greek Civil Code and establish the civil liability of those who caused the environmental damage and bear responsibility for that. In conclusion, all the International Conventions, that have been ratified by Greece and establish a notable civil liability regime for the person who caused the environmental pollution and liable to pay compensation, are fully recorded and thoroughly analyzed.

Liangshan Yi folk song
Creators: name: Zhou, Li
Publisher: name: University of British Columbia
Year: 2008

description: This thesis examines the relationship between the folk songs of the Liangshan Yi of China and other aspects of their culture. Special attention is given to the social function of these folk songs. On the basis of musical analyses, the author believes that three important features can be identified. These are syncopation of rhythm as influenced by lyrics, simple single-phrase structure with plain melodic contour and subdued emotive musical expression. These characteristics are deeply rooted in Yi culture, since most Liangshan Yi folk songs are performed to serve specific social functions, especially in religious and ceremonial communication. In addition, the songs as emotional expression reflect the influence of traditional ideology and the general temperament of the people.
Asymptotic Estimation for Eigenvalues in the Exponential Potential and for Zeros of $K_{{\rm i}ν}(z)$ with Respect to Order

description: The paper presents the derivation of the asymptotic behavior of $ν$-zeros of the modified Bessel function of imaginary order $K_{{\rm i}ν}(z)$. This derivation is based on the quasiclassical treatment of the exponential potential on the positive half axis. The asymptotic expression for the $ν$-zeros (zeros with respect to order) contains the Lambert $W$ function, which is readily available in most computer algebra systems and numerical software packages. The use of this function provides much higher accuracy of the estimation comparing to known relations containing the logarithm, which is just the leading term of $W(x)$ at large $x$. Our result ensures accuracies sufficient for practical applications.

Publisher: name: University of British Columbia
Year: 2008

description: This M.A. thesis is a critical study of two contemporary Chinese novels: Jia Pingwa’s Turbulence and Zhang Wei’s The Old Boat. The purpose of this study is to demonstrate the two novels’ achievements and limitations in portraying the images of Chinese peasants in the reform era. Chapter One provides the synopses of these works and discusses their repercussions in China. It also gives a brief account of the authors’ backgrounds and the two novels’ social and literary milieu. Chapter Two discusses the thematic similarities and differences of these works, with an emphasis on the ideological breakthroughs demonstrated in the themes. Chapter Three and Chapter Four analyse four groups of characters, mainly from the social and historical perspective. The first group consists of the protagonists. Discussion concentrates on the characteristics of these protagonists as educated peasants and the conflicts between the opposing desires and values within their respective temperaments. The second group is made up of two characters who believe in “combating evil with evil”. The complexities of their personalities and the meanings of their failures are explored. The third group comprises the villains. Attention is focused on the negative aspect of the peasant revolution and the influence of the clan system. The fourth group includes a few supporting characters. Chapter Five deals with the artistic techniques employed by the authors in characterization. It examines how the two authors present the personalities and feelings of the characters by the reproduction of their speech and movement, or through the descriptions of the physical settings. This chapter also probes the functions of the symbols used in these works. Chapter Six draws some conclusions based on the above discussion. It points out the meanings of these works in the context of modern Chinese literature.

description: Quasi-two-dimensional kagome metals AV3Sb5 (A = K, Rb, and Cs) have attracted much recent interest due to exotic quantum phenomena such as unconventional superconductivity, topological charge order and giant anomalous Hall effect. Here we report pressure-induced reemergent superconductivity in CsV3Sb5 by electrical transport measurements under high pressures up to 47.9 GPa. We show that the superconducting critical temperature Tc is first enhanced by pressure and reaches its first maximum ~ 8.9 K at 0.8 GPa, then the Tc is suppressed by pressure and cannot be detected above 7.5 GPa, forming a dome-shaped superconducting phase diagram. Remarkably, upon further compression above 16.5 GPa, a new superconducting state arises, of which Tc is enhanced by pressure to a second maximum ~ 5.0 K and the reemergent superconductivity keeps robust up to 47.9 GPa. Combined with high-pressure synchrotron x-ray diffraction measurements that demonstrate the stability of the pristine hexagonal phase up to 43.1 GPa, we suggest that the reemergence of superconductivity in the V-based superconductor could be attributed to a pressure-induced Lifshitz transition.

description: We present the results from a spectroscopic monitoring campaign to obtain reverberation-mapping measurements and investigate the broad-line region kinematics for active galactic nuclei (AGN) of Mrk~817 and NGC~7469. This campaign was undertaken with the Lijiang 2.4-meter telescope, the median spectroscopic sampling is 2.0 days for Mrk~817 and 1.0 days for NGC~7469. We detect time lags of the broad emission lines including H$β$, H$γ$, He~{\sc ii} and He~{\sc i} for both AGNs, and including Fe~{\sc ii} for Mrk~817 with respect to the varying AGN continuum at 5100~Å. Investigating the relationship between line widths and time lags of the broad emission lines, we find that the BLR dynamics of Mrk~817 and NGC~7469 are consistent with the virial prediction. We estimate the masses of central supermassive black hole (SMBH) and the accretion rates of both AGNs. Using the data of this campaign, we construct the velocity-resolved lag profiles of the broad H$γ$, H$β$, and He~{\sc i} lines for Mrk~817, which show almost the same kinematic signatures that the time lags in the red wing are slightly larger than the time lags in the blue wing. For NGC~7469, we only clearly construct the velocity-resolved lag profiles of the broad H$γ$ and H$β$, which show very similar kinematic signatures to the BLR of Mrk~817. These signatures indicate that the BLR of Keplerian motion in both AGNs seemingly has outflowing components during the monitoring period. We discuss the kinematics of the BLR and the measurements including SMBH mass and accretion rates.

description: We analyze the experimental observation of metastable anisotropy resistance orientation at half filled quantum Hall fluids by means of a model of a quantum nematic liquid in an explicit symmetry breaking potential. We interpret the observed ``rotation'' of the anisotropy axis as a process of nucleation of nematic domains and compute the nucleation rate within this model. By comparing with experiment, we are able to predict the critical radius of nematic bubbles, $R_c\sim 2.6 μm $. Each domain contains about $10^4$ electrons.

A modified discrepancy principle to attain optimal convergence rates under unknown noise

Publisher: name: arXiv
Year: 2021
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: We consider a linear ill-posed equation in the Hilbert space setting. Multiple independent unbiased measurements of the right hand side are available. A natural approach is to take the average of the measurements as an approximation of the right hand side and to estimate the data error as the inverse of the square root of the number of measurements. We calculate the optimal convergence rate (as the number of measurements tends to infinity) under classical source conditions and introduce a modified discrepancy principle, which asymptotically attains this rate.

It is shown that its signal drops at a (pseudo-)critical chemical potential mu_c. The Polyakov loop and the chiral condensate undergo their transitions at the same value. Pauli blocking supervenes at a value of the chemical potential larger than mu_c.

We show that every separately holomorphic mapping $f: W:=(A\times Y) \cup (X\times B)\longrightarrow Z$ extends to a holomorphic mapping $\hat{f}$ on $\hat{W}:=\left\lbrace(z,w)\in X\times Y:\ \widetildeω(z,A,X)+\widetildeω(w,B,Y)<1 \right\rbrace$ such that $\hat{f}=f$ on $W\cap \hat{W},$ where $\widetildeω(\cdot,A,X)$ (resp. $\widetildeω(\cdot,B,Y))$ is the plurisubharmonic measure of $A$ (resp. $B$) relative to $X$ (resp. $Y$). Generalizations of this result for an $N$-fold cross are also given.

description: The main focus of the present paper is on teachers’ knowledge and beliefs towards dyslexia and dyslectic students in Greece and to what extent postgraduate studies have contributed to their shaping. This study used seventy-five (n=75) Greek teachers of English who are employed in the state sector. The data was collected through an online questionnaire and two semi-structured interviews. The questionnaire included questions about teachers’ knowledge and self-perception of knowledge of dyslexia, the factors that impede them from teaching dyslectic students and the beliefs they have about them. Results indicated that a great number of English teachers have several common misconceptions about dyslexia and this is evident in their self-perception and in the factors that refrain them from effective teaching. The study finally revealed that the teachers’ beliefs are controversial and that postgraduate studies influence mostly them rather than their knowledge. The paper aims to explore in depth the aforementioned issues, suggest some possible explanations for the outcomes and discuss the implications that are derived from the results.
description: Η παρούσα έρευνα εστιάζει στη μελέτη των γνώσεων και των απόψεων των εκπαιδευτικών σχετικά με τη δυσλεξία και τους μαθητές με δυσλεξία και κατά πόσο οι μεταπτυχιακές σπουδές τους τούς έχουν επηρεάσει. 75 Έλληνες καθηγητές Αγγλικής Γλώσσας που δουλεύουν στη δημόσια πρωτοβάθμια και δευτεροβάθμια εκπαίδευση της χώρας ήταν το δείγμα της έρευνας. Τα εργαλεία συλλογής δεδομένων ήταν ένα ερωτηματολόγιο που διανεμήθηκε ηλεκτρονικά και δύο ημι-δομημένες συνεντεύξεις. Το ερωτηματολόγιο περιείχε ερωτήσεις σχετικά με τις γνώσεις και την αυτοαντίληψη των εκπαιδευτικών όσον αφορά τη δυσλεξία, τους παράγοντες που τους εμποδίζουν να διδάξουν μαθητές με δυσλεξία και τις απόψεις που έχουν για εκείνους. Τα αποτελέσματα έδειξαν ότι αρκετοί εκπαιδευτικοί Αγγλικής Γλώσσας έχουν κοινές παρανοήσεις σχετικά με τη δυσλεξία και αυτό γίνεται εμφανές τόσο στην αυτοαντίληψη που έχουν όσο και στους παράγοντες που τους παρεμποδίζουν από μια επιτυχή διδασκαλία. Τέλος, έγινε φανερό ότι οι απόψεις των εκπαιδευτικών σχετικά με τους μαθητές με δυσλεξία είναι αμφιλεγόμενες και ότι οι μεταπτυχιακές σπουδές επηρεάζουν σε μεγαλύτερο βαθμό τις απόψεις τους και όχι τις γνώσεις τους. Σκοπός της έρευνας είναι να διερευνηθούν τα προαναφερθέντα ζητήματα, να προταθούν και να συζητηθούν πιθανές αιτίες για τα αποτελέσματα.

description: Amorphe Kohlenstoffschichten zeichnen sich durch eine hohe Härte, niedrige Reibung und hohe Verschleißbeständigkeit aus und sind daher effektive Schichtsysteme zur Verbesserung des Reib- und Verschleißverhaltens von tribologisch beanspruchten Werkzeugen. Diese kohlenstoffbasierten Dünnschichten weisen allerdings eine niedrige Haftung auf metallischen Substraten auf. Da adhäsive Schichtschädigungen zu einem frühzeitigen Werkzeugausfall führen, ist eine hohe Haftfestigkeit der amorphen Kohlenstoffschichten auf dem Werkzeugstahl entscheidend für die tribologische Leistungsfähigkeit und eine langlebige Einsatzzeit des beschichteten Werkzeugs. Dieser Herausforderung wird mit der Entwicklung einer Substrat/Schichtgestaltung zur Steigerung der Schichthaftung auf den Werkzeugstählen und der Anpassung der tribo-mechanischen Eigenschaften begegnet. Die Prozesskette, bestehend aus der Plasmavorbehandlung der Werkzeugstähle und der nachfolgenden Synthese einer chemisch gradierten Zwischenschicht sowie einer multilagigen Funktionsschicht aus amorphem Kohlenstoff, wird systematisch in Abhängigkeit des verwendeten Werkzeugstahls untersucht. Dabei werden verschiedene Verfahrensvarianten der Magnetron-Kathodenzerstäubung für die Substratvorbehandlung und Schichtsynthese genutzt.

description: Monte Carlo algorithms are frequently used in atomistic simulations, including for computation of magnetic parameter temperature dependences in multiscale simulations. Even though parallelization strategies for Monte Carlo simulations of lattice spin models are known, its application to computation of magnetic parameter temperature dependences is lacking in the literature. Here we show how, not only the unconstrained algorithm, but also the constrained atomistic Monte Carlo algorithm, can be parallelized. Compared to the serial algorithms, the parallel Monte Carlo algorithms are typically over 200 times faster, allowing computations in systems with over 10 million atomistic spins on a single GPU with relative ease. Implementation and testing of the algorithms was carried out in large-scale systems, where finite-size effects are reduced, by accurately computing temperature dependences of magnetization, uniaxial and cubic anisotropies, exchange stiffness, and susceptibilities. In particular for the exchange stiffness the Bloch domain wall method was used with a large crosssectional area, which allows accurate computation of the domain wall width up to the Curie temperature. The exchange stiffness for a simple cubic lattice closely follows an mk scaling at low temperatures, with k < 2 dependent on the anisotropy strength. However, close to the Curie temperature the scaling exponent tends to k = 2. Furthermore, the implemented algorithms are applied to the computation of magnetization temperature dependence in granular thin films with over 15 million spins, as a function of average grain size and film thickness. We show the average Curie temperature in such systems may be obtained from a weighted Bloch series fit, which is useful for analysis of experimental results in granular thin films.

description: We report the results of the first two 5 GHz e-VLBI observations of the X-ray binary Cygnus X-3 using the European VLBI Network. Two successful observing sessions were held, on 2006 April 20, when the system was in a quasi-quiescent state several weeks after a major flare, and on 2006 May 18, a few days after another flare. At the first epoch we detected faint emission probably associated with a fading jet, spatially separated from the X-ray binary. The second epoch in contrast reveals a bright, curved, relativistic jet more than 40 milliarcseconds in extent. In the first, and probably also second epochs, the X-ray binary core is not detected, which may indicate a temporary suppression of jet production as seen in some black hole X-ray binaries in certain X-ray states. Spatially resolved polarisation maps at the second epoch provide evidence of interaction between the ejecta and the surrounding medium. These results clearly demonstrate the importance of rapid analysis of long-baseline observations of transients, such as facilitated by e-VLBI.

Cournot Competition and “Green” Innovation: An Inverted-U Relationship

description: We examine the relationship between competition and innovation in an industry where production is polluting and R&D aims to reduce emissions (“green” innovation). We present an n-firm oligopoly where firms compete in quantities and decide their investment in “green” R&D.
When environmental taxation is exogenous, aggregate R&D investment always increases with the number of firms in the industry. Next we analyse the case where the emission tax is set endogenously by a regulator (committed or time-consistent) with the aim to maximise social welfare. We show that an inverted-U relationship exists between aggregate R&D and industry size under reasonable conditions, and is driven by the presence of R&D spillovers.

description: We prove existence of maximal entropy measures for an open set of non-uniformly expanding local diffeomorphisms on a compact Riemannian manifold. In this context the topological entropy coincides with the logarithm of the degree, and these maximizing measures are eigenmeasures of the transfer operator. When the map is topologically mixing, the maximizing measure is unique and positive on every open set.

description: The main goal of the present paper is to evaluate the perturbed locations and investigate the linear stability of the triangular points. We studied the problem in the elliptic restricted three body problem frame of work. The problem is generalized in the sense that the two primaries are considered as triaxial bodies. It is found that the locations of these points are affected by the triaxiality coefficients of the primaries and the eccentricity of orbits. Also it is observed that the stability regions depend on the involved perturbations. In addition to this we studied the periodic orbits in the vicinity of the triangular points.

description: We consider quantum backreaction of the quantized scalar field with an arbitrary mass and curvature coupling on ultraextremal horizons. The problem is distinguished in that (in contrast to non-extremal or extremal black holes) the WKB approximation remains valid near $r_{+}$ (which is the radius of the horizon) even in the massless limit. We examine the behavior of the stress-energy tensor of the quantized field near $r_{+}$ and show that quantum-corrected objects under discussion do exist. In the limit of the large mass our results agree with previous ones known in literature.

description: Λέγει ο Άγιος Σιλουανός ο Αθωνίτης ότι ο άνθρωπος επιθυμεί να γνωρίσει τον τρόπο με τον οποίο δημιουργήθηκε ο ήλιος και ακούει μία φωνή από τον Θεό να του λέει «Ταπείνωσε το πνεύμα σου και θα γνωρίσεις όχι μόνο τον ήλιο αλλά και τον δημιουργό του και όταν γνωρίσεις τον δημιουργό του τότε οποιαδήποτε άλλη γνώση θα είναι περιττή » . Ο άνθρωπος προσπαθεί συνεχώς να ανακαλύψει την φύση και τα μυστικά της. Δημιουργεί ακατάπαυστα θαυμαστά έργα, αναπτύσσει επιστήμες και δημιουργεί τεχνολογικές εφαρμογές. Όλα αυτά είναι δωρήματα και ευλογίες του Θεού που δόθηκαν στον άνθρωπο, για να τα διαχειριστεί επ' αγαθώ της κοινωνίας. Οφείλουμε να θέσουμε στην υπηρεσία του Θεού όλα τα δώρα της πρόνοιας Του, ώστε να παραχθούν μόνο ωφέλημα αποτελέσματα για τον άνθρωπο. Σε αυτή την διπλωματική εργασία μελετώνται τα Μεγάλα Δεδομένα (Big Data) τα οποία έχουν δημιουργηθεί από την ανάπτυξη της τεχνολογίας και από την παραγωγή μεγάλου όγκου πληροφορίας. Η εξαγωγή γνώσης από την μελέτη ομάδων μεγάλων δεδομένων είναι πολύτιμη και συναντάται σε πολλά επιστημονικά πεδία. Στην παρούσα εργασία εστιάζουμε στην μελέτη δεδομένων μεγάλου όγκου θεολογικού περιεχομένου
description: Saint Silouan the Athonite says that man wishes to know how the sun was created and hears the voice of God telling him "Humble your spirit and you shall know not only the sun but even its creator, and since you know its creator than any other knowledge will be unnecessary."Man tries constantly to discover nature and its secrets. He ceaselessly creates amazing artwork and develops sciences and technological applications. All these are gifts and blessings from God given to man for the purpose of use to the benefit of society. We are obligated to put all gifts of His providence in the service of God in order that only beneficial to man outcome be produced. The present thesis researches Big Data created by the development of technology and production of large information volume. The knowledge extraction from the study of big data groups is valuable and apparent in many scientific fields. In this thesis we will attempt to study large amount data of theological content
