description: This paper proposes a novel cell-based neural architecture search algorithm (NAS), which completely alleviates the expensive costs of data labeling inherited from supervised learning. Our algorithm capitalizes on the effectiveness of self-supervised learning for image representations, which is an increasingly crucial topic of computer vision. First, using only a small amount of unlabeled train data under contrastive self-supervised learning allow us to search on a more extensive search space, discovering better neural architectures without surging the computational resources. Second, we entirely relieve the cost for labeled data (by contrastive loss) in the search stage without compromising architectures' final performance in the evaluation phase. Finally, we tackle the inherent discrete search space of the NAS problem by sequential model-based optimization via the tree-parzen estimator (SMBO-TPE), enabling us to reduce the computational expense response surface significantly. An extensive number of experiments empirically show that our search algorithm can achieve state-of-the-art results with better efficiency in data labeling cost, searching time, and accuracy in final validation.

description: The quantum theory of rotation angles (S. M. Barnett and D. T. Pegg, Phys. Rev. A, 41, 3427-3425 (1990)) is generalised to non-integer values of the orbital angular momentum. This requires the introduction of an additional parameter, the orientation of a phase discontinuity associated with fractional values of the orbital angular momentum. We apply our formalism to the propagation of light modes with fractional orbital angular momentum in the paraxial and non-paraxial regime.

Interactions between an integrated deaf child of hearing parents and his hearing partners in the school setting: a vygoskian perspective
Creators: name: Shaw, Jeanne Annette
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this research was to describe, from a Vygotskian perspective, the nature and quality of the social interactions experienced by a fully integrated deaf child of hearing parents (dchp) in the school setting. Because social transmission of information is one of the key ways that members acquire social knowledge and because dchp do not have easy access to reciprocal communication with the hearing adults and peers who surround them, it was anticipated that examination of the social interaction processes would yield important information about the cultural knowledge of the deaf child. A case study research design was used, focussing on the interactions of an eight year-old male dchp who had been fully integrated among hearing peers. The dchp was videotaped for nine hours in both social and instructional settings. The videotapes were analyzed to determine patterns of communicative action. The dchp was found to interact primarily with girls in social settings and with the Sign Language interpreter in instructional settings. He seldom initiated interactions and responded only briefly to most of his partners' contributions. Linguistic semiotic mediation was used to discuss a limited number of topics and was usually highly contextualized. Although many communication breakdowns were not repaired, however, reciprocal dialogues between the deaf child and hearing partners who signed well were also noted. Unexpected findings emerged regarding the effects of the Sign Language interpreter during interaction between the classroom teacher and the deaf student. The case study design was found to be a pedagogically useful tool. Overall, the findings are consistent with Vygotsky's theory of child development.

description: We investigated the tunnelling dynamics of a zero-temperature Bose-Einstein condensate (BEC) in configuration of four potential wells arranged in a loop. We found three interesting dynamic regimes: (a) flows of matter with small amplitude, (b) steady flow and (c) forced flow of matter for large amplitudes. The regime of quantum self-confinement has been studied and a new variant of it has been found for this system.

description: We only see a small fraction of the matter in the universe, but the rest gives itself away by the impact of its gravity. The distortions from pure Hubble flow (or peculiar velocities) that this matter creates have the potential to be a powerful cosmological tool, but are also a nuisance for extragalactic astronomers who wish to use redshifts to estimate distances to local galaxies. We provide a quick overview of work on the local peculiar velocity field, discussing both simple spherical infall models, non-parametric modeling using redshifts surveys, and full velocity and density field reconstruction from peculiar velocities. We discuss results from a multiattractor model fit to data from the SFI++ sample of peculiar velocities - the best peculiar velocity data currently available. We also talk about the future of samples for the study of the local velocity field, especially the 2MASS Tully-Fisher (2MTF) survey.

description: Ελληνική Περίληψη Η παρούσα διπλωματική έχει ως θέμα τη διατηρητέα κατοικία στην οδό Βαφοπούλου 17, στην περιοχή Ντεπό της Θεσσαλονίκης. Πρόκειται για διώροφο οικοδόμημα, που η ανέγερσή του χρονολογείται στα μέσα της δεκαετίας του 1920, και αποτελεί αντιπροσωπευτικό δείγμα της αρχιτεκτονικής πολυτελούς αστικής μονοκατοικίας την εποχή του Μεσοπολέμου. Στη διάρκεια της μελέτης συλλέχθηκαν ιστορικά στοιχεία, σχετικά έγγραφα και χάρτες από την Εφορεία Νεωτέρων Μνημείων Κεντρικής Μακεδονίας, από το αρχείο της ΚΕΔ καθώς το εν λόγω κτίριο αποτελεί ιδιοκτησία του Ελληνικού Δημοσίου, και από τα αρχεία (παλαιά τοπογραφικά, αντίστοιχα ΦΕΚ, και φωτογραφίες) του κ. Βασίλη Πλαστήρα κάτοικο διπλανής πολυκατοικίας. Στη συνέχεια έγινε τοπογραφική αποτύπωση του κτιρίου με γεωδαιτικό σταθμό Total Station TS02 της εταιρίας Leica Geosysytems εξωτερικά σε όλη την περίμετρό του. Ακολούθησε η αρχιτεκτονική αποτύπωση εσωτερικά με αποστασιόμετρο τύπου Bosch και μετροταινία για τις λεπτομέρειες, και προέκυψαν τα πλήρη και ακριβή σχέδια αποτύπωσης, σε μια προσπάθεια ολοκληρωμένης απόδοσης των οικοδομικών φάσεων του κτιρίου, της υφιστάμενης κατάστασής του, και της παθολογίας του. Με βάση τα παραπάνω δεδομένα και με σεβασμό στην ιστορικότητα του μνημείου, συνυπολογίζοντας και το αμείωτο ενδιαφέρον των περίοικων για την συντήρησή του, επελέγησαν οι αντίστοιχες εργασίες αποκατάστασης και διατήρησης της οικίας μέσω μιας ήπιας πρότασης επανάχρησης, έτσι ώστε να επανενταχθεί αρμονικά στον αστικό ιστό και να αποτραπεί η κατάρρευσή του λόγω εγκατάλειψης.
description: The theme of this diploma essay is the conserved house of Vafopoulou 17, at Ntepo of Thessaloniki. It is a building with two levels, that was constructed at the mid 1920’s, a fine example of luxury architecture of urban houses at the age o Middle War. During the research there were collected historical elements, papers and maps from the Ministry of Culture of Central Macedonia, from the archives of Greek State and from mister Vasileios Plastiras resident of the neighborhood of the residence. The topographical survey of the exterior of the building was made with a Total Station TS02 of Leica Geosystems. The architectural survey of the interior of the building was made with a range finder and a measure, in order to have all the plans and designing models completed, as well as the constructive fases and the pathology. At the end, after the fulfill of the architectural analysis of the residence at Vafopoulou 17, there were chosen several tasks for the conservation and the restoration of the building, as well as a proposal for a mild re-use of it so as to avoid the abandonment and the collapse of the historic monument.

description: We study the magnetoelectric and magnetothermal transport properties of noncentrosymmetric metals using semiclassical Boltzmann transport formalism by incorporating the effects of Berry curvature and orbital magnetic moment. These effects impart quadratic-B dependence to the magnetoelectric and magnetothermal conductivities, leading to intriguing phenomena such as planar Hall effect, negative magnetoresistance, planar Nernst effect and negative Seebeck effect. The transport coefficients associated with these effects show the usual oscillatory behavior with respect to the angle between the applied electric field and magnetic field. The bands of noncentrosymmetric metals are split by Rashba spin-orbit coupling except at a band touching point. For Fermi energy below (above) the band touching point, giant (diminished) negative magnetoresistance is observed. This difference in the nature of magnetoresistance is related to the magnitudes of the velocities, Berry curvature and orbital magnetic moment on the respective Fermi surfaces, where the orbital magnetic moment plays the dominant role. The absolute magnetoresistance and planar Hall conductivity show a decreasing (increasing) trend with Rashba coupling parameter for Fermi energy below (above) the band touching point.

description: In the Greek legal order hate crime is regulated in the Penal Code, in article 79 par. 3, that states: “Committing a crime out of hate due to the victim’s race, color, religion, genealogical background, national or ethnic origin or sexual orientation or gender identity constitutes an aggravating condition and the penalty cannot be suspended”. The present paper attempts a theoretical approach to hate crime, starting with a general description and examining certain issues that arise, such as the non-suspension of the penalty. The main issue examined is whether, according to criminal law theory, it is justifiable to treat hate crime differently and impose enhanced penalties. Therefore, the main part of this paper is devoted to analyzing the arguments for and against this enhanced punishment, with respect to actus reus as well as with respect to mens rea, and concludes with pinpointing the harm caused to the vested legal interest of human dignity as that carrying the extra denunciation that justifies an enhanced penalty.

description: Group consensus implies reaching multiple groups where agents belonging to the same cluster reach state consensus. This paper focuses on linear multi-agent systems under nonnegative directed graphs. A new necessary and sufficient condition for ensuring group consensus is derived, which requires the spanning forest of the underlying directed graph and that of its quotient graph induced with respect to a clustering partition to contain equal minimum number of directed trees. This condition is further shown to be equivalent to containing cluster spanning trees, a commonly used topology for the underlying graph in the literature. Under a designed controller gain, lower bound of the overall coupling strength for achieving group consensus is specified. Moreover, the pattern of the multiple consensus states formed by all clusters is characterized when the overall coupling strength is large enough.

The Cult of Mount Tyai in the Ming: baliefs, practices and historical developments
Creators: name: Shiau, Mei-Hui
Publisher: name: University of British Columbia
Year: 2009

description: This thesis explores the cult of Mount T'ai in the Ming dynasty (1368-1644) by examining its beliefs, practices and historical developments. The first chapter introduces the religious environment of the Ming by addressing the historical background of the founder of the Ming, Ming T'ai-tsu (r. 1368-1398), and his policy toward popular religions. T'ai-tsu's background influenced his views about religion, and his attitudes were followed, to some extent, by his descendants, later emperors. The last part provides a summary of the environment of ordinary people's religions and their religious practices. Since the Mount T'ai cult had existed long before the Ming, chapter two summarizes this cult prior to the Ming by discussing its early history and the early history of the role of Mount T'ai in beliefs about afterlife. Chapter three examines the cult of Mount T'ai in the Ming from three perspectives: as a state cult, a popular cult, and as the most popular cult of the goddess of Mount T'ai during the Ming. This chapter suggests that the development of these cults was closely linked to the ongoing changes in popular culture and the the attitudes of the state toward religions. Chapter four turns to religious and social activities related to Mount T'ai. In analyzing the incense tax, which was levied on pilgrims and visitors entering Mount T'ai, the pilgrimage trade, and the attitudes of the Ming elites toward popular beliefs about Mount T'ai, I suggest that religious activities were an area where people of all social classes, including the educated level, routinely came into contact. Chapter five discusses two seventeenth century religious texts about Mount T'ai: Lina-vina T'ai-shan niang-niana pao-chuan (The precious volume of our efficacious Lady of Mount T'ai) and T'ai-shan tung-yueh shih-wang paochuan (The precious volume of the Ten Kings of the eastern peak Mount T'ai). This chapter explores these two books in terms of their connections to three teachings (Buddhism, Taoism, and Confucianism), sectarianism, and the attitudes of the religious groups toward the state. The concluding comments characterize the interactions between popular religions, the state, and society. The cult of Mount T'ai developed in a context of socio-religious culture through a process of mutual enrichment.

description: One of the main goal of large-scale structure surveys is to test the consistency of General Relativity at cosmological scales. In the $Λ$CDM model of cosmology, the relations between the fields describing the geometry and the content of our Universe are uniquely determined. In particular, the two gravitational potentials -- that describe the spatial and temporal fluctuations in the geometry -- are equal. Whereas large classes of dark energy models preserve this equality, theories of modified gravity generally create a difference between the potentials, known as anisotropic stress. Even though measuring this anisotropic stress is one of the key goals of large-scale structure surveys, there are currently no methods able to measure it directly. Current methods all rely on measurements of galaxy peculiar velocities (through redshift-space distortions), from which the time component of the metric is inferred, assuming that dark matter follows geodesics. If this is not the case, all the proposed tests fail to measure the anisotropic stress. In this letter, we propose a novel test which directly measures anisotropic stress, without relying on any assumption about the unknown dark matter. Our method uses relativistic effects in the galaxy number counts to provide a direct measurement of the time component of the metric. By comparing this with lensing observations our test provides a direct measurement of the anisotropic stress.

description: We present new Very Large Array (VLA) observations toward NGC 253 of the recombination line H53alpha (43 GHz) at an angular resolution of 1.''5 X 1.''0. The free-free emission at 43 GHz is estimated to be ~100 mJy, implying a star formation rate of ~1.3 Msun/yr in the nuclear region of this starburst galaxy. A reanalysis is made for previously reported H92alpha observations carried out with angular resolution of 1.''5 X 1.''0 and 0.''36 X 0.''21. Based on the line and continuum emission models used for the 1.''5 X 1.''0 angular resolution observations, the RRLs H53alpha and H92alpha are tracers of the high-density (~10^5 cm-3) and low-density (~10^3 cm^-3) thermally ionized gas components in NGC 253, respectively. The velocity fields observed in the H53alpha and H92alpha lines 1.''5 X 1.''0) are consistent. The velocity gradient in the central ~18 pc of the NE component, as observed in both the H53alpha and H92alpha lines, is in the opposite direction to the velocity gradient determined from the CO observations. The enclosed virial mass, as deduced from the H53alpha velocity gradient over the NE component, is ~5 X 10^6 Msun in the central ~18 pc region. The H92alpha line observations at high angular resolution (0.''36 X 0.''21) reveal a larger velocity gradient, along a P.A. ~ -45 deg on the NE component, of ~110 km/s/arcsec. The dynamical mass estimated using the high angular resolution H92alpha data (~7 X 10^6 Msun) supports the existence of an accreted massive object in the nuclear region of NGC 253.

Hard label black box attack on text classification
Creators: name: Saxena, Sachin
Publisher: name: No Publisher Supplied
Year: 2021

description: Machine learning has been proven to be susceptible to carefully crafted samples, known as adversarial examples. The generation of these adversarial examples helps to make the models more robust and gives us an insight into the underlying decision-making of these models. Over the years, researchers have successfully attacked image classifiers in both white and black-box settings. However, these methods are not directly applicable to texts as text data is discrete. In recent years, research on crafting adversarial examples against textual applications has been on the rise. In this thesis work, we present a novel approach for hard-label black-box attacks against Natural Language Processing (NLP) classifiers, where no model information is disclosed, and an attacker can only query the model to get the final decision of the classifier, without confidence scores of the classes involved. Such an attack scenario applies to real-world black-box models being used for security-sensitive applications such as sentiment analysis and toxic content detection.

description: Cramér and Leadbetter introduced in 1967 the sufficient condition \[\frac{r''(s)-r''(0)}{s}\in L^1([0,δ],dx),\qquad δ>0,\] to have a finite variance of the number of zeros of a centered stationary Gaussian process with twice differentiable covariance function $r$. This condition is known as the Geman condition, since Geman proved in 1972 that it was also a necessary condition. Up to now no such criterion was known for counts of crossings of a level other than the mean. This paper shows that the Geman condition is still sufficient and necessary to have a finite variance of the number of any fixed level crossings. For the generalization to the number of a curve crossings, a condition on the curve has to be added to the Geman condition.

description: Στην παρούσα εργασία παρουσιάζεται και αναλύεται η ελληνική εξωτερική πολιτική προς την ΠΓΔΜ μετά το τέλος του Ψυχρού πολέμου, οπότε επανήλθε στο προσκήνιο το Μακεδονικό Ζήτημα, με ένταση και συναισθηματική φόρτιση που παράπεμπαν σε περιόδους πριν από τον Ψυχρό Πόλεμο. Πρόκειται για μια περίοδο που χαρακτηρίζεται από διάφορες φάσεις. Η κυριότερη φάση (1992-1995) σημαδεύεται από πολιτικές αντιπαράθεσης με τη νεοπαγή δημοκρατία, οι οποίες βασίζονται σε μια αυστηρή και αδιάλλακτη στάση για το ζήτημα του ονόματος. Η διαμάχη των ετών 1992-1995 είχε σημαντικές επιπτώσεις για την περιοχή, επηρέασε και επηρεάστηκε από την εσωτερική πολιτική σκηνή και τις κομματικές ισορροπίες, τόσο στην Ελλάδα όσο και στην ΠΓΔΜ. Ωστόσο μετά την υπογραφή της Ενδιάμεσης Συμφωνίας από τις δύο χώρες το 1995, αναδύεται σταδιακά μια άλλη φάση εξελίξεων. Η πολιτική της Ελλάδας αλλάζει επιδιώκοντας πλέον μια αμοιβαία επωφελή συνεργασία με την ΠΓΔΜ, με ιδιαίτερη έμφαση στην οικονομική προσέγγιση. Αναλύονται τέλος οι διαπραγματεύσεις των τελευταίων ετών, τα προσκόμματα που τέθηκαν από την ελληνική κυβέρνηση στην προσπάθεια της γειτονικής χώρας να γίνει μέλος του ΝΑΤΟ και η έντονη αντίδραση της κυβέρνησης της ΠΓΔΜ με την προσφυγή της στο Διεθνές Δικαστήριο της Χάγης.
description: This paper presents and analyzes the Greek foreign policy towards Macedonia after the end of the Cold War , when the Macedonian Question was revived, with intensity and emotion which refers to periods prior to the Cold War. It is a period that is characterized by several phases. The main phase (1992-1995) was marked by political conflict and rivalry with the newly established democracy, based on a strict and uncompromising position on the name issue. The controversy over the years 1992-1995 had a significant impact on the area affected and influenced by internal politics , both in Greece and Macedonia . However, after the signing of the Interim Agreement by both countries in 1995, gradually emerges another phase. Greece's policy changes now seeking a mutually beneficial cooperation with FYROM , with particular emphasis on the economic approach. Finally, there is an analysis of the recent negotiations, the obstacles posed by the Greek government in the effort of the neighboring country to join NATO and the strong reaction of the FYROM government to this that has led it to appeal to the International Court of Justice.

description: We study the formation of (quasi-)coherent matter waves emerging from a Mott insulator for strongly interacting bosons on a one-dimensional lattice. It has been shown previously that a quasi-condensate emerges at momentum k=π/2a, where a is the lattice constant, in the limit of infinitely strong repulsion (hard-core bosons). Here we show that this phenomenon persists for all values of the repulsive interaction that lead to a Mott insulator at a commensurate filling. The non-equilibrium dynamics of hard-core bosons is treated exactly by means of a Jordan-Wigner transformation, and the generic case is studied using a time-dependent density matrix renormalization group technique. Different methods for controlling the emerging matter wave are discussed.

description: Galactic supernova remnants (SNRs) with angular dimensions greater than a few degrees are relatively rare, as are remnants located more than ten degrees off the Galactic plane. Here we report a UV and optical investigation of two previously suspected SNRs more than ten degrees in both angular diameter and Galactic latitude. One is a proposed remnant discovered in 2008 through 1420 MHz polarization maps near Galactic coordinates $l$ = 353, $b$ = $-$34. GALEX far UV (FUV) and H$α$ emission mosaics show the object's radio emission coincident with a 11 x 14 degree shell of UV filaments surrounding a diffuse H$α$ emission ring. Another proposed high latitude SNR is the 20 x 26 degree Antlia nebula (G275.5+18.4) discovered in 2002 through low-resolution all-sky H$α$ and ROSAT soft X-ray emissions. GALEX UV and H$α$ mosaics along with optical spectra indicate the presence of shocks throughout the Antlia nebula with estimated shock velocities of 70 to over 100 km s$^{-1}$. We also present evidence that it has collided with the northeast rim of the Gum Nebula. We find both of these nebulae are bona fide SNRs with ages less than 10$^{5}$ yr despite their unusually large angular dimensions. We also present FUV and optical images along with optical spectra of a new high-latitude SNR (G249.7+24.7) some 4.5 degrees in diameter which has also been independently discovered in X-rays and radio (Becker at al. 2021). We find this remnant's distance to be $\leq$400 pc based on the detection of red and blue shifted Na I absorption features in the spectra of two background stars.

description: We give lower bounds for the density $p_T(x,y)$ of the law of $X_t$, the solution of $dX_t=σ(X_t) dB_t+b(X_t) dt,X_0=x,$ under the following local ellipticity hypothesis: there exists a deterministic differentiable curve $x_t, 0\leq t\leq T$, such that $x_0=x, x_T=y$ and $σσ^*(x_t)>0,$ for all $t\in \lbrack 0,T].$ The lower bound is expressed in terms of a distance related to the skeleton of the diffusion process. This distance appears when we optimize over all the curves which verify the above ellipticity assumption. The arguments which lead to the above result work in a general context which includes a large class of Wiener functionals, for example, Itô processes. Our starting point is work of Kohatsu-Higa which presents a general framework including stochastic PDE's.

description: The present thesis aims in the study of the coefficient of variation through sampling and applications. Initially, in chapter 1 we perform an approach of the term sampling, we describe briefly the basic methods, stressing the commodity of research and generally in the field of Statistics.In continuation, in chapter 2, we report statistic measures and we focus in disperse measures and especially in the coefficient of Variance. We define it (Cv), we present it through examples and then we report the formulas of weighted and unweighted (Cv).Finally, we record some applications of coefficient of Variance and its existence in other sciences.In continuation, in chapter 3, we study the probability density function in a symmetric and in an increasing arbitrary variable. More specifically, we present the methodology followed for the estimation of the specific probability density functions with the assistance of Cv. Finally, the theory-methodology for the better understanding “accompanied” by applications.

description: A wave function exposed to measurements undergoes pure state dynamics, with deterministic unitary and probabilistic measurement induced state updates, defining a quantum trajectory. For many-particle systems, the competition of these different elements of dynamics can give rise to a scenario similar to quantum phase transitions. To access it despite the randomness of single quantum trajectories, we construct an $n$-replica Keldysh field theory for the ensemble average of the $n$-th moment of the trajectory projector. A key finding is that this field theory decouples into one set of degrees of freedom that heats up indefinitely, while $n-1$ others can be cast into the form of pure state evolutions generated by an effective non-Hermitian Hamiltonian. This decoupling is exact for free theories, and useful for interacting ones. In particular, we study locally measured Dirac fermions in $(1+1)$ dimensions, which can be bosonized to a monitored interacting Luttinger liquid at long wavelengths. For this model, the non-Hermitian Hamiltonian corresponds to a quantum Sine-Gordon model with complex coefficients. A renormalization group analysis reveals a gapless critical phase with logarithmic entanglement entropy growth, and a gapped area law phase, separated by a Berezinskii-Kosterlitz-Thouless transition. The physical picture emerging here is a pinning of the trajectory wave function into eigenstates of the measurement operators upon increasing the monitoring rate.
