description: The role of spin-orbit interaction on the ground state and thermal entanglement of a Heisenberg XYZ two-qubit system in the presence of an inhomogeneous magnetic field is investigated. For a certain value of spin-orbit parameter $D$, the ground state entanglement tends to vanish suddenly and when $D$ crosses its critical value $D_c$, the entanglement undergoes a revival. The maximum value of the entanglement occurs in the revival region. In finite temperatures there are revival regions in $D-T$ plane. In these regions, entanglement first increases with increasing temperature and then decreases and ultimately vanishes for temperatures above a critical value. This critical temperature is an increasing function of $D$, thus the nonzero entanglement can exist for larger temperatures. In addition, the amount of entanglement in the revival region depends on the spin-orbit parameter. Also, the entanglement teleportation via the quantum channel constructed by the above system is investigated and finally the influence of the spin-orbit interaction on the fidelity of teleportation and entanglement of replica state is studied.

description: A desirable property of learning systems is to be both effective and interpretable. Towards this goal, recent models have been proposed that first generate an extractive explanation from the input text and then generate a prediction on just the explanation called explain-then-predict models. These models primarily consider the task input as a supervision signal in learning an extractive explanation and do not effectively integrate rationales data as an additional inductive bias to improve task performance. We propose a novel yet simple approach ExPred, that uses multi-task learning in the explanation generation phase effectively trading-off explanation and prediction losses. And then we use another prediction network on just the extracted explanations for optimizing the task performance. We conduct an extensive evaluation of our approach on three diverse language datasets -- fact verification, sentiment classification, and QA -- and find that we substantially outperform existing approaches.

Accuracy improvements for interior residual stress measurements
Creators: name: Liu, Xue Mei
Publisher: name: University of British Columbia
Year: 2009

description: The accuracy of interior residual stress measurements using the layer-removal, hole-drilling and ring-core methods was enhanced in two ways. In the first way, the mathematical method for calculating residual stresses from the measured strains was made more robust by applying an inverse solution method based on Linear Inverse Theory. This approach eliminates the two main weaknesses of the existing method, stress solution sensitivity to strain measurement errors and not obeying equilibrium. Optimal smoothing is introduced as an effective method for reducing sensitivity to strain data errors. With the proposed method, stress equilibrium can be easily enforced. Both experimental and theoretical results show that the inverse solution method stabilizes the calculation procedure and it is an effective and reliable method for determining residual stresses in a material. The second way of enhancing residual stress measurement is to develop a new residual stress measurement technique. The new technique, called ring-hole drilling, overcomes the limitations of strain sensitivity to subsurface stresses of the hole-drilling and ring-core methods. By moving the strain gauges from the material surface to the interior, the overall strain sensitivity of the ring-hole drilling method is increased to double that of the ring-core method, and about four times that of the hole-drilling method. The experimental measurements made with ring-hole method correspond very closely with theoretical expectations determined using finite element method. The results show that ring-hole drilling is a practical method for evaluating residual stresses in a material.

description: Characterizing the galaxy population in the early Universe holds the key to understanding the evolution of these objects and the role they played in cosmic reionization. However, the number of observations at the very highest redshifts are to date, few. In order to shed light on the properties of galaxies in the high-redshift Universe and their interstellar media, we observe the Lyman-$α$ emitting galaxy z7\_GSD\_3811 at $z=7.664$ with band 6 and 8 at the Atacama Large Millimeter/submillimeter Array (ALMA). We target the far-infrared [O III] 88 $μm$, [C II] 158 $μm$ emission lines and dust continuum in the star-forming galaxy z7\_GSD\_3811 with ALMA. We combine these measurements with earlier observations in the rest-frame ultraviolet (UV) in order to characterize the object, and compare results to those of earlier studies observing [O III] and [C II] emission in high-redshift galaxies. The [O III] 88 $μm$ and [C II] 158 $μm$ emission lines are undetected at the position of z7\_GSD\_3811, with $3σ$ upper limits of $1.6 \ \times \ 10^{8} \ L_{\odot}$ and $4.0 \ \times \ 10^{7} \ L_{\odot}$, respectively. We do not detect any dust continuum in band 6 nor band 8. The measured rms in the band 8 and band 6 continuum is 26 and 9.9 $μJy \ beam^{-1}$, respectively. Similar to several other high-redshift galaxies, z7\_GSD\_3811 exhibits low [C II] emission for its star formation rate compared to local galaxies. Furthermore, our upper limit on the [O III] line luminosity is lower than all the previously observed [O III] lines in high-redshift galaxies with similar ultraviolet luminosities. Our ALMA band 6 and 8 dust continuum observations imply that z7\_GSD\_3811 likely has a low dust content, and our non-detections of the [O III] and [C II] lines could indicate that z7\_GSD\_3811 has a low metallicity ($Z \lesssim 0.1 \ Z_{\odot}$).

description: The aim of the present thesis is to present the interaction between the European Arrest Warrant (hereinafter EAW) and the fundamental rights of the requested person during its execution. Initially, an attempt is made to clarify the meaning and content of the principle of mutual recognition, as well as the basic elements of the EAW, as a tool for its implementation. Afterwards, the issue of the conflict between the principle of mutual recognition and the fundamental rights of the requested person is analyzed and the limits that the protection of these rights places on the principle of mutual recognition. Furthermore, an overview of the jurisprudence of the CJEU is attempted, with a presentation of key decisions, which demonstrate the repercussions between the relationship of mutual recognition and fundamental rights. In conclusion, the paper aims to draw conclusions from the effect of the protection of fundamental rights on the execution of the EAW, through the evaluation of the evolution of the jurisprudence of the CJEU.

description: A large and ideal Rashba-type spin-orbit splitting is desired for the applications of materials in spintronic devices and the detection of Majorana Fermions in solids. Here, we propose an approach to achieve giant and ideal spin-orbit splittings through a combination of ordered surface alloying and interface engineering, that is, growing alloy monolayers on an insulating polar surface. We illustrate this unique strategy by means of first-principles calculations of buckled hexagonal monolayers of SbBi and PbBi supported on Al$_2$O$_3$(0001). Both systems display ideal Rashba-type states with giant SO splittings, characterized with energy offsets over 600 meV and momentum offsets over 0.3 $Å^{-1}$, respectively. Our study thus points to an effective way of tuning spin-orbit splitting in low-dimensional materials to draw immediate experimental interest.

description: Let $(M,I,J,K)$ be a hyperkaehler manifold, $\dim_\R M =4n$. We study positive, Dolbeault-closed $(2p,0)$-forms on $(M,I)$. These forms are quaternionic analogues of the positive $(p,p)$-forms. We construct an injective homomorphism mapping Dolbeault-closed $(2p,0)$-forms to closed $(n+p,n+p)$-forms, and positive $(2p,0)$-forms to positive $(n+p,n+p)$-forms. This construction is used to prove a hyperkaehler version of the classical Skoda-El Mir theorem, which says that a trivial extension of a closed, positive current over a pluripolar set is again closed. We also prove the hyperkaehler version of the Sibony's lemma, showing that a closed, positive $(2p,0)$-form defined outside of a compact complex subvariety $Z\subset (M,I)$, $\codim Z > 2p$ is locally integrable in a neighbourhood of $Z$. These results are used to prove polystability of derived direct images of certain coherent sheaves.

description: For the multiple differential algebra of iterated differential forms (see math.DG/0605113 and math.DG/0609287) on a diffiety (O,C) an analogue of C-spectral sequence is constructed. The first term of it is naturally interpreted as the algebra of secondary iterated differential forms on (O,C). This allows to develop secondary tensor analysis on generic diffieties, some simplest elements of which are sketched here. The presented here general theory will be specified to infinite jet spaces and infinitely prolonged PDEs in subsequent notes.

description: Passive filtering is a common strategy to reduce airborne disease transmission and particulate contaminants across scales spanning orders of magnitude. The engineering of high-performance filters with relatively low flow resistance but high virus- or particle-blocking efficiency is a non-trivial problem of paramount relevance, as evidenced in the variety of industrial filtration systems and face masks. Next-generation industrial filters and masks should retain sufficiently small droplets and aerosols while having low resistance. We introduce a novel 3D-printable particle filter inspired by animals’ complex nasal anatomy. Unlike standard random-media-based filters, the proposed concept relies on equally spaced channels with tortuous airflow paths. These two strategies induce distinct effects: a reduced resistance and a high likelihood of particle trapping by altering their trajectories with tortuous paths and induced local flow instability. The structures are tested for pressure drop and particle filtering efficiency over different airflow rates. We have also cross-validated the observed efficiency through numerical simulations. We found that the designed filters exhibit a lower pressure drop, compared to commercial masks and filters, while capturing particles bigger than approximately μm

description: Many scholars have recently focused on traffic congestion to find a solution and reduce the significant economic losses it causes. In this context, studying the speed and flow characteristics of roads helps to develop ways to manage traffic more efficiently. The main goal of this study is to suggest ideas for traffic improvements in the three selected intersections in Pabna City. The legs of these intersections are composed of both motorized vehicles (Bus, Passenger cars etc.) and non-motorized vehicles (Bicycles, Cycle rickshaws, Carts etc.). A VISSIM model (a traffic microscopic simulation software) is calibrated and validated to build a road network, identify and optimize problems, and visualize the results. Accordingly, this study evaluates the present traffic flow condition, creates signalized intersections on the three existing roundabout intersections, and analyses the congestion costs. The study shows that the developed VISSIM model significantly improves vehicular flows and speeds and reduces the travel time of trip-makers without installing new infrastructure to the existing road capacity. The congestion cost at the developed signalized intersections on the roundabout intersections is reduced by 30% per hour at Pabna-Sujanagar Hwy. It decreases by 31% at Ataikhula road and A. Hamid Road by 24% per hour.
Computational modelling of manifold type flowspreaders

Publisher: name: University of British Columbia
Year: 2009

description: A computational model is developed for the prediction of flow distribution in manifold type flowspreaders. To address the difficulties associated with complex configurations of manifold type flowspreaders and convergence problems, several numerical techniques are used, including curvilinear coordinate-based calculations and domain segmentation. A 3D curvilinear coordinate-based CFD code, called CMGFD, which can be used to calculate laminar/turbulent flows in arbitrary geometries using curvilinear grids is adapted. To support the application of the CMGFD code, a multigrid elliptic grid generation code, MBEGG, was modified to generate multi-block curvilinear grids for the CMGFD code. Validation of these methods is performed. The calculation of flow in liquid cooling module manifolds shows that the predicted flow rate in each channel is in good agreement with other numerical studies; the calculated cross-stream motions at different locations agree well with experimental data for the turbulent flow modelling in a pipe junction, . A Canfor manifold type flow spreader, which includes a tapered rectangular duct with 560 tubes, is modelled. The effects of spreader recirculation rate and inlet flow rate on the flow distribution have been considered. The computational results show that the numerical tool has the ability to model the flow distribution of manifold type flowspreaders.

XMCD measurements allow us to investigate element-selective magnetic proximity effects at the very TI/EuS interface. A systematic analysis reveals that there is neither significant induced magnetism within the TI nor an enhancement of the Eu magnetic moment at such interface. The induced magnetic moments in Bi, Sb, Te, and Se sites are lower than the estimated detection limit of the XMCD measurements of $\sim\!10^{-3}$ $μ_\mathrm{B}$/at.

Αναγνωρίστηκαν και ταυτοποιήθηκαν 169 είδη φυτών, που ανήκουν συνολικά σε 48 οικογένειες, εκ των οποίων τα 45 είδη είναι υδρόβια μακρόφυτα. Για τα κυριότερα από αυτά έχει δοθεί μια σύντομη περιγραφή.Τα υδρόβια μακρόφυτα συμβάλλουν στην διατήρηση των υγροτοπικών λειτουργειών και αξιών του ποταμού και μπορεί να αποτελέσουν δείκτες της ποιότητας των νερών. Η κατανόηση των λειτουργειών και αξιών του ποταμού Λουδία μπορεί να οδηγήσει στη σύνταξη και εφαρμογή κατάλληλων διαχειριστικών σχεδίων στη λεκάνη απορροής του.
description: The river Loudias constitutes a modified wetland in central Macedonia. It was created by the drainage of the lake Giannitsa and the surrounding marshlands. The river is influenced by the sea tides of the Thermaikos gulf and it is affected by human activities. The main anthropogenic sources of pollution are industrial and urban wastes.The main objective of the present work was to do the inventory of the wetland flora and the plants of the coastal area of the Loudias river. One hundred and sixty nine species were identified which belong to forty eight families, forty five species are aquatic macrophytes and some of them have been briefly described. These plants contribute to the wetland functions and values and they can be indices of the water quality.The understanding of these functions and values can lead to the construction and implementation of the appropriate management plans in the watershed of the river

description: Το θέμα της εργασίας είναι το έργο της ζωγράφου Σοφίας Λασκαρίδου. Στην εισαγωγή παρατίθενται πληροφορίες για τη μεθοδολογία της εργασίας και για τη ζωή της ζωγράφου. Στο πρώτο κεφάλαιο γίνεται μνεία για τη θέση της γυναίκας στην κοινωνία και την τέχνη των αρχών του 20ου αιώνα. Επειτα εξετάζεται η υποδοχή του έργου και της προσωπικότητας της Λασκαρίδου, και διαπιστώνεται ότι με την πάροδο των χρόνων το έργο της έπεσε σε λήθη, ενώ αντίθετα η ίδια αποτέλεσε πηγή έμπνευσης για λογοτέχνες και καλλιτέχνες. Στη συνέχεια αναλύεται το έργο της ζωγράφου, με βασικό άξονα το θεματολογικό και διερευνάται η σχέση του με τα ρεύματα της καλλιτεχνικής πρωτοπορίας-κυριότερα τον εμπρεσιονισμό, τον εξπρεσιονισμό και το συμβολισμό. Μετά τα τελικά συμπεράσματα ακολουθεί παράρτημα με τις εικόνες των έργων, πίνακα εκθέσεων όπου συμμετείχε η Λασκαρίδου, χρονολογικό πίνακα και παρατηρήσεις πάνω στην υπογραφή της. Βασικό στοιχείο είναι ο αναλυτικός κατάλογος των έργων που ανέδειξε η έρευνα, ενώ δεν παραλείπονται σχόλια πάνω σε μη γνήσια έργα που αποδίδονται στη ζωγράφο
description: The subject is the work of the painter Sofia Laskaridou. In the introduction there is information on the methodology of the project and the life of the painter. The first chapter is dedicated to an inquiry into woman's place in the society and art of the beginning of the 20th century.Afterwards i look into the reception of the work and personality of Laskaridou and i find out that as time went by her work fell into oblivion, whreas her personality became a source of inspiration to writers and artists. Her work is analyzed next, with an order based on their subjects and emphasis being given to the paintings relation to movements of the avant-garde, especially empressionism, expressionims and symbolism. After the conclusion, there is an annex with paintings, tables about her life and work, observations on her signature and nongenuine works and an analytical catalogue of her paintings

description: Word alignments identify translational correspondences between words in a parallel sentence pair and are used, for instance, to learn bilingual dictionaries, to train statistical machine translation systems or to perform quality estimation. Variational autoencoders have been recently used in various of natural language processing to learn in an unsupervised way latent representations that are useful for language generation tasks. In this paper, we study these models for the task of word alignment and propose and assess several evolutions of a vanilla variational autoencoders. We demonstrate that these techniques can yield competitive results as compared to Giza++ and to a strong neural network alignment system for two language pairs.

description: M87 is a key object whose study can reveal the complex phenomena in cooling cores. We use a deep XMM-Newton observation of M87 to produce detailed temperature, pressure and entropy maps in order to analyze the physical processes of cooling cores and of their heating mechanisms. We employed both broad-band fitting and full spectroscopical one-temperature model analysis to derive temperature and surface brightness maps, from which the pseudo-deprojected entropy and pressure were calculated. We discuss possible physical interpretations of small deviations from radial and elliptical symmetry in these maps. The most prominent features observed are the E and SW X-ray arms that coincide with powerful radio lobes, a weak shock at a radius of 3', an overall ellipticity in the pressure map and a NW/SE asymmetry in the entropy map which we associate with the motion of the galaxy towards the NW. For the first time we find evidence that cold, metal-rich gas is being transported out of the center, possibly through bubble-induced mixing. Several edges in the abundance map indicate an oscillation of the galaxy along the NW/SE direction. Furthermore, the radio lobes appear to rise along the short axis of the elliptical pressure distribution, following the steepest gradient of the gravitational potential, and seem to contain a nonthermal pressure component.

description: Here, we report the detection of phosphorus and fluorine in solid particles collected from the inner coma of comet 67P/Churyumov-Gerasimenko measured with the COmetary Secondary Ion Mass Analyser (COSIMA) instrument on-board the Rosetta spacecraft, only a few kilometers away from the comet nucleus. We have detected phosphorus-containing minerals from the presented COSIMA mass spectra, and can rule out e.g. apatite minerals as the source of phosphorus. This result completes the detection of life-necessary CHNOPS-elements in solid cometary matter, indicating cometary delivery as a potential source of these elements to the young Earth. Fluorine was also detected with CF$^+$ secondary ions originating from the cometary dust.

description: This work explores scattering amplitudes that couple two-particle systems via a single external current insertion, $2+\mathcal{J}\to 2$. Such amplitudes can provide structural information about the excited QCD spectrum. We derive an exact analytic representation for these reactions. From these amplitudes, we show how to rigorously define resonance and bound-state form-factors. Furthermore, we explore the consequences of the narrow-width limit of the amplitudes as well as the role of the Ward-Takahashi identity for conserved vector currents. These results hold for any number of two-body channels with no intrinsic spin, and a current with arbitrary Lorentz structure and quantum numbers. This work and the existing finite-volume formalism provide a complete framework for determining this class of amplitudes from lattice QCD.

description: We explore the origin of a population of stars recently detected in the inner parsec of the Milky Way Nuclear Cluster (NC), which exhibit sub-solar metallicity and a higher rotation compared to the dominant population. Using state-of-the-art $N$-body simulations, we model the infall of a massive stellar system into the Galactic center, both of Galactic and extra-galactic origin. We show that the newly discovered population can either be the remnant of a massive star cluster formed a few kpc away from the Galactic center (Galactic scenario) or be accreted from a dwarf galaxy originally located at 10-100 kpc (extragalactic scenario) and that reached the Galactic center 3-5 Gyr ago. A comparison between our models and characteristic Galactocentric distance and metallicity distributions of Milky Way satellites and globular clusters favours the Galactic scenario. A comparison with clusters associated with the Enceladus-Sausage, Sequoia, Sagittarius and Canis Major structures suggests that the progenitor of the observed metal-poor substructure formed in-situ rather than being accreted.

Τόσο στην Πολιτεία όσο και στους Νόμους, ο Πλάτων ξεδιπλώνει την αυστηρή κριτική του και θέτει όρους και κανόνες για τις τέχνες, αναγνωρίζοντας τον τεράστιο ρόλο τους και τη βαθιά επιρροή τους στην εξέλιξη των νέων και μελλοντικών Φυλάκων της Πολιτείας του
description: To the present essay are being examined the views of Plato about the potentiality of the arts-poetry, music, painting, sculpture etc- to affect the formation of the ethos and character of the young, in a positive or negative way, during the educational process and also later in the social environment, how they do this through from, content, representation and up to what grade. In the Republic as well as in the Laws, Plato unfolds his sever critique and places limits and rules to the arts, cknowledging the huge role and deep infuence they have to the development of the young's and also future Guardians of the Republic

Η μαθηματική προσομοίωση της ποιότητας του νερού δίνει τη δυνατότητα της χωροχρονικής μελέτης των πιο σημαντικών ποιοτικών παραμέτρων τους, όπως η θερμοκρασία, το διαλυμένο οξυγόνο (DO), η βιοχημική ζήτηση σε οξυγόνο (BOD), η αμμωνία (NA4), τα νιτρικά (NO3), τα ορθοφωσφορικά (OPO4), δηλαδή οι παράγοντες του ευτροφισμού. Το WASP αποτελεί ένα μαθηματικό μοντέλο πεπερασμένων διαφορών, που περιγράφει την κατανομή των ποιοτικών παραμέτρων στη λίμνη Παμβώτιδα, η οποία δέχεται μεγάλες ποσότητες απόβλητων, λόγω των γεωργικών δραστηριοτήτων στην ευρύτερη περιοχή, αλλά και λόγω των παρακείμενων βιομηχανικών μονάδων. Η εφαρμογή του μοντέλου αποτελεί εργαλείο για τη λήψη μέτρων για ολοκληρωμένη διαχείριση της ρύπανσης

description: The diploma paper of my postgraduate title was written in the year 2000. At this point the first law concerning the cadastral survey had appeared. The diploma paper concerns the securing of the correctness of the first registrations. That means on one hand the correct registration of the real estate and on the other hand mainly the correct registration of the property rights on this particular real estate. The provisions of the law where predicting ways in order to protect the correcthness of the first registrations, which where exhibited analytically and commented regarding their efficiency
