description: We introduce an Eulerian Perturbation Theory to study the clustering of tracers for cosmologies in the presence of massive neutrinos. Our approach is based on mapping recently-obtained Lagrangian Perturbation Theory results to the Eulerian framework. We add Effective Field Theory counterterms, IR-resummations and a biasing scheme to compute the one-loop redshift-space power spectrum. To assess our predictions, we compare the power spectrum multipoles against synthetic halo catalogues from the Quijote simulations, finding excellent agreement on scales $k\lesssim 0.25 \,h \text{Mpc}^{-1}$. One can obtain the same fitting accuracy using higher wave-numbers, but then the theory fails to give a correct estimation of the linear bias parameter. We further discuss the implications for the tree-level bispectrum. Finally, calculating loop corrections is computationally costly, hence we derive an accurate approximation wherein we retain only the main features of the kernels, as produced by changes to the growth rate. As a result, we show how FFTLog methods can be used to further accelerate the loop computations with these reduced kernels.

Free energy and defect $C$-theorem in free fermion

description: We describe a $p$-dimensional conformal defect of a free Dirac fermion on a $d$-dimensional flat space as boundary conditions on a conformally equivalent space $\mathbb{H}^{p+1} \times \mathbb{S}^{d-p-1}$. We classify allowed boundary conditions and find that the Dirichlet type of boundary conditions always exists while the Neumann type of boundary condition exists only for a two-codimensional defect. For the two-codimensional defect, a double trace deformation triggers a renormalization group flow from the Neumann boundary condition to the Dirichlet boundary condition, and the free energy at UV fixed point is always larger than that at IR fixed point. This provides us with further support of a conjectured $C$-theorem in DCFT.

Strategies for observing extreme mass ratio inspirals

description: I review the status of research, conducted by a variety of independent groups, aimed at the eventual observation of Extreme Mass Ratio Inspirals (EMRIs) with gravitational wave detectors. EMRIs are binary systems in which one of the objects is much more massive than the other, and which are in a state of dynamical evolution that is dominated by the effects of gravitational radiation. Although these systems are highly relativistic, with the smaller object moving relative to the larger at nearly light-speed, they are well described by perturbative calculations which exploit the mass ratio as a natural small parameter. I review the use of such approximations to generate waveforms needed by data analysis algorithms for observation. I also briefly review the status of developing the data analysis algorithms themselves. Although this article is almost entirely a review of previous work, it includes (as an appendix) a new analytical estimate for the time over which the influence of radiation on the binary itself is observationally negligible.

ResDepth: A Deep Residual Prior For 3D Reconstruction From High-resolution Satellite Images

description: Modern optical satellite sensors enable high-resolution stereo reconstruction from space. But the challenging imaging conditions when observing the Earth from space push stereo matching to its limits. In practice, the resulting digital surface models (DSMs) are fairly noisy and often do not attain the accuracy needed for high-resolution applications such as 3D city modeling. Arguably, stereo correspondence based on low-level image similarity is insufficient and should be complemented with a-priori knowledge about the expected surface geometry beyond basic local smoothness. To that end, we introduce ResDepth, a convolutional neural network that learns such an expressive geometric prior from example data. ResDepth refines an initial, raw stereo DSM while conditioning the refinement on the images. I.e., it acts as a smart, learned post-processing filter and can seamlessly complement any stereo matching pipeline. In a series of experiments, we find that the proposed method consistently improves stereo DSMs both quantitatively and qualitatively. We show that the prior encoded in the network weights captures meaningful geometric characteristics of urban design, which also generalize across different districts and even from one city to another. Moreover, we demonstrate that, by training on a variety of stereo pairs, ResDepth can acquire a sufficient degree of invariance against variations in imaging conditions and acquisition geometry.

description: It was recently shown in hep-th/0610334 that in the context of the ISS models with a metastable supersymmetry breaking vacuum, thermal effects generically drive the Universe to the metastable vacuum even if it began after inflation in the supersymmetry-preserving one. We continue this programme and specifically take into account two new effects. First is the effect of the mass-gap of the gauge degrees of freedom in the confining supersymmetry preserving vacua, and second, is the effect of the back reaction of the MSSM sector on the SUSY breaking ISS sector. It is shown that, even though the mass-gap is parametrically smaller than the vevs, it drastically reduces the temperature required for the Universe to be driven to the metastable vacuum: essentially any temperature larger than the supersymmetry breaking scale μis sufficient. On the other hand we also find that any reasonable transmission of SUSY breaking to the MSSM sector has no effect on the vacuum transitions to, and the stability of the SUSY breaking vacuum. We conclude that for these models the early Universe does end up in the SUSY breaking vacuum.

description: The aim of the present thesis is to highlight the main features of the crime of misappropriation of funds, presenting all the problems of criminal law that have arisen, issues which have been the subject of intense controversy in both science and jurisprudence. Furthermore, we referred to a substantive intervention that has been made by the case law of the Greek courts in the formation of this crime, which in terms of interpretation has brought about substantial changes in the criminal treatment of the offense, which the common legislator has not yet incorporated into the legislative form. Finally, in the third chapter of the present, the presentation of Law 1608/1950 was made, from the precursor regulation to its present form and the amendments that the law endured throughout its lifetime. In view of the inclusion of the offense of misappropriation of funds in the list of offenses under Law 1608/1950, we would be remiss if we did not comment on the problems of a general nature which this law faces, and in particular the question of the emerging widening of the concept of public property, and the manner in which the offense under Article 256 of the Criminal Code is included in the framework of its implementation

description: We propose a semiconductor-superconductor hybrid device for realizing topological superconductivity and Majorana zero modes consisting of a planar Josephson junction structure with periodically modulated junction width. By performing a numerical analysis of the effective model describing the low-energy physics of the hybrid structure, we demonstrate that the modulation of the junction width results in a substantial enhancement of the topological gap and, consequently, of the robustness of the topological superconducting phase and associated Majorana zero modes. This enhancement is due to the formation of minibands with strongly renormalized effective parameters, including stronger spin-orbit coupling, generated by the effective periodic potential induced by the modulated structure. In addition to a larger topological gap, the proposed device supports a topological superconducting phase that covers a significant fraction of the parameter space, including the low Zeeman field regime, in the absence of a superconducting phase difference across the junction. Furthermore, the optimal regime for operating the device can be conveniently accessed by tuning the potential in the junction region using, for example, a top gate.

description: An analytic method is proposed to compute the surface energy and elementary excitations of the XXZ spin chain with generic non-diagonal boundary fields. For the gapped case, in some boundary parameter regimes the contributions of the two boundary fields to the surface energy are non-additive. Such a correlation effect between the two boundaries also depends on the parity of the site number $N$ even in the thermodynamic limit $N\to\infty$. For the gapless case, contributions of the two boundary fields to the surface energy are additive due to the absence of long-range correlation in the bulk. Although the $U(1)$ symmetry of the system is broken, exact spinon-like excitations, which obviously do not carry spin-$\frac12$, are observed. The present method provides an universal procedure to deal with quantum integrable systems either with or without $U(1)$ symmetry.

A Universal Decline Law of Classical Novae. II. GK Persei 1901 and Novae in 2005

description: Optical and infrared light-curves of classical novae are approximately homologous among various white dwarf (WD) masses and chemical compositions when free-free emission from optically thin ejecta dominates the continuum flux of novae. Such a homologous template light-curve is called a ``universal decline law.'' The timescale of the light curve depends strongly on the WD mass but weakly on the chemical composition, so we are able to roughly estimate the WD mass from the light-curve fitting. We have applied the universal decline law to the old nova GK Persei 1901 and recent novae that outbursted in 2005. The estimated WD mass is 1.15 M_sun for GK Per, which is consistent with a central value of the WD mass determined from the orbital velocity variations. The other WD masses of 10 novae in 2005 are also estimated to be 1.05 M_sun (V2361 Cyg), 1.15 M_sun (V382 Nor), 1.2 M_sun (V5115 Sgr), 0.7 M_sun (V378 Ser), 0.9 M_sun (V5116 Sgr), 1.25 M_sun (V1188 Sco), 0.7 M_sun (V1047 Cen), 0.95 M_sun (V476 Sct), 0.95 M_sun (V1663 Aql), and 1.30 M_sun (V477 Sct), within a rough accuracy of +- 0.1 M_sun. Four (V382 Nor, V5115 Sgr, V1188 Sco, and V477 Sct) of ten novae in the year 2005 are probably neon novae on an O-Ne-Mg WD. Each WD mass depends weakly on the chemical composition (especially the hydrogen content X in mass weight), i.e., the obtained WD masses increase by +0.5(X-0.35) M_sun for the six CO novae and by +0.5(X-0.55) M_sun for the four neon novae above. Various nova parameters are discussed in relation to its WD mass.

description: We map the infinite-range coupled quantum kicked rotors over an infinite-range coupled interacting bosonic model. In this way we can apply exact diagonalization up to quite large system sizes and confirm that the system tends to ergodicity in the large-size limit. In the thermodynamic limit the system is described by a set of coupled Gross-Pitaevskij equations equivalent to an effective nonlinear single-rotor Hamiltonian. These equations give rise to a power-law increase in time of the energy with exponent $γ\sim 2/3$ in a wide range of parameters. We explain this finding by means of a master-equation approach based on the noisy behaviour of the effective nonlinear single-rotor Hamiltonian and on the Anderson localization of the single-rotor Floquet states. Furthermore, we study chaos by means of the largest Lyapunov exponent and find that it decreases towards zero for portions of the phase space with increasing momentum. Finally, we show that some stroboscopic Floquet integrals of motion of the noninteracting dynamics deviate from their initial values over a time scale related to the interaction strength according to the Nekhoroshev theorem.

description: We present optical spectroscopy of a sample of 77 luminous AGN and quasars selected on the basis of their mid-infrared colors. Our objects are selected from the Spitzer Extragalactic First Look Survey and SWIRE XMM-LSS fields, with a typical 24mu flux density of 5mJy. The median redshift is 0.6, with a range of ~0.05-4. Only 33% (25/77) of these objects are normal type-1 quasars, with no obscuration. 44% (34/77) are type-2 objects, with high-ionization, narrow emission lines, 14% (11/77) are dust-reddened type-1 quasars, showing broad lines but a dust-reddened or unusually weak quasar continuum. 9% (7/77) show no sign of an AGN in the optical spectrum, having either starburst spectra or spectra which could be of either starburst or LINER types. These latter objects are analogous to the X-ray detected population of AGN with weak or non-existent optical AGN emission (the ``XBONGs''). 21 of our objects from the SWIRE field fall within moderately-deep XMM exposures. All the unobscured quasars, and about half the obscured quasars are detected in these exposures. This sample, when taken together with other samples of Spitzer selected AGN and quasars, and results from X-ray studies, confirms that obscured AGN dominate the AGN and quasar number counts of all rapidly-accreting supermassive black hole systems, at least for z~<4. This implies a high radiative efficiency for the black hole accretion process.

description: Let Gamma_k be the lower central series of a surface group Gamma of a compact surface S with one boundary component. A simple question to ponder is whether a mapping class of S can be determined to be pseudo-Anosov given only the data of its action on Gamma/Gamma_k for some k. In this paper, to each mapping class f which acts trivially on Gamma/Gamma_{k+1}, we associate an invariant Psi_k(f) in End(H_1(S, Z)) which is constructed from its action on Gamma/Gamma_{k+2} . We show that if the characteristic polynomial of Psi_k(f) is irreducible over Z, then f must be pseudo-Anosov. Some explicit mapping classes are then shown to be pseudo-Anosov.

description: We present a flexible public transit network design model which optimizes a social access objective while guaranteeing that the system's costs and transit times remain within a preset margin of their current levels. The purpose of the model is to find a set of minor, immediate modifications to an existing bus network that can give more communities access to the chosen services while having a minimal impact on the current network's operator costs and user costs. Design decisions consist of reallocation of existing resources in order to adjust line frequencies and capacities. We present a hybrid tabu search/simulated annealing algorithm for the solution of this optimization-based model. As a case study we apply the model to the problem of improving equity of access to primary health care facilities in the Chicago metropolitan area. The results of the model suggest that it is possible to achieve better primary care access equity through reassignment of existing buses and implementation of express runs, while leaving overall service levels relatively unaffected.

This study clarified the synthesis conditions under which low and high magnetic defect concentrations can be obtained within the spinel structure of LiV2O4. We confirmed that the LiV2O4 phase can be obtained containing low (0.006 mol%) to high (0.83 mol%) magnetic defect concentrations n{defect} and with consistently high magnetic defect spin S values between 3 and 6.5. The high n{defect} values were obtained in the LiV2O4 phase in equilibrium with V2O3, Li3VO4, or LiVO2 and the low values in the LiV2O4 phase in equilibrium with V3O5. A model is suggested to explain this correlation.

The model considered takes into account both the charge exchange couplings, responsible for superconducting orderings, and the density-density interactions, which can stabilize charge ordered states in the system. Depending on the strength of the random on-site potential, the interactions and the particle concentrations the model is found to exhibit several various phases, including the homogeneous ones: superconducting (SC), charge density wave (CDW) and nonordered (NO), as well as the phase separated states (CDW-SC and CDW-NO).

A comparison with a 1998 BeppoSAX observation suggests that XMM-Newton caught the source in a `reflection-dominated' phase, measuring the lowest continuum flux level ever (F(2-10 keV) = 2.3 x 10^(-12) erg cm^-2 s^-1) in 2005. NGC 7582 therefore experienced a dramatic spectral transition most likely due to the partial switching-off of the nuclear activity. The XMM-Newton spectrum of the continuum emission is very complex. It can be well described by a model consisting of a combination of a heavily absorbed (Nh ~ 10^(24) cm^-2) power law and a pure reflection component both obscured by a column density of ~ 4 x 10^(22) cm^-2. Notably, we detect a significant increase by a factor of ~2 in the column density of the inner, thicker absorber covering the primary X-ray source between 2001 and 2005. The 2005 XMM-Newton spectra show the strongest Fe Kalpha emission line ever measured in this source. This is consistent with the line delayed time response to the decrease of the nuclear activity. Our analysis also reveals that the soft X-ray spectrum is dominated by emission lines from highly ionized metals. The detection of a narrow OVIII radiative recombination continuum suggests an origin in a photoionized plasma.

description: We present the spectra of 14 quasars with a wide coverage of rest wavelengths from 1000 to 7300 A. The redshift ranges from z = 0.061 to 0.555 and the luminosity from M_{B} = -22.69 to -26.32. We describe the procedure of generating the template spectrum of Fe II line emission from the spectrum of a narrow-line Seyfert 1 galaxy I Zw 1 that covers two wavelength regions of 2200-3500 A and 4200-5600 A. Our template Fe II spectrum is semi-empirical in the sense that the synthetic spectrum calculated with the CLOUDY photoionization code is used to separate the Fe II emission from the Mg II line. The procedure of measuring the strengths of Fe II emission lines is twofold; (1) subtracting the continuum components by fitting models of the power-law and Balmer continua in the continuum windows which are relatively free from line emissions, and (2) fitting models of the Fe II emission based on the Fe II template to the continuum-subtracted spectra. From 14 quasars, we obtained the Fe II fluxes in five wavelength bands, the total flux of Balmer continuum, and the fluxes of Mg II, Halpha, and other emission lines, together with the full width at half maxima (FWHMs) of these lines. Regression analysis was performed by assuming a linear relation between any two of these quantities. Eight correlations were found with a confidence level higher than 99%. The fact that six of these eight are related to FWHM or M_{BH} may imply that M_{BH} is a fundamental quantity that controls Gamma or the spectral energy distribution (SED) of the incident continuum, which in turn controls the Fe II emission. Furthermore, it is worthy of noting that Fe II(O1)/Fe II(U1) is found to tightly correlate with Fe II(O1)/Mg II, but not with Fe II(U1)/Mg II.

description: We consider a multilevel hydrogen atom in interaction with the quantum electromagnetic field and separately calculate the contributions of the vacuum fluctuation and radiation reaction to the rate of change of the mean atomic energy of the atom for uniform acceleration. It is found that the acceleration disturbs the vacuum fluctuations in such a way that the delicate balance between the contributions of vacuum fluctuation and radiation reaction that exists for inertial atoms is broken, so that the transitions to higher-lying states from ground state are possible even in vacuum. In contrast to the case of an atom interacting with a scalar field, the contributions of both electromagnetic vacuum fluctuations and radiation reaction to the spontaneous emission rate are affected by the acceleration, and furthermore the contribution of the vacuum fluctuations contains a non-thermal acceleration-dependent correction, which is possibly observable.

description: Instability of electron-positron vacuum in strong electric fields is studied. First, falling to the Coulomb center is discussed at $Z>137/2$ for a spinless boson and at $Z>137$ for electron. Then, focus is concentrated on description of deep electron levels and spontaneous positron production in the field of a finite-size nucleus with the charge $Z>Z_{\rm cr}\simeq 170$. Next, these effects are studied in application to the low-energy heavy-ion collisions. Then, we consider phenomenon of "electron condensation" on levels of upper continuum crossed the boundary of the lower continuum $ε=-m$ in the field of a supercharged nucleus with $Z\gg Z_{\rm cr}$. Finally, attention is focused on many-particle problems of polarization of the QED vacuum and electron condensation at ultra-short distances from a source of charge. We argue for a principal difference of cases, when the size of the source is larger than the pole size $r_{\rm pole}$, at which the dielectric permittivity of the vacuum reaches zero, and smaller $r_{\rm pole}$. Some arguments are presented in favor of the logical consistency of QED. All problems are considered within the same relativistic semiclassical approach.

description: Η Ορθόδοξη Εκκλησία εορτάζει την Ίνδικτο ως έναρξη του εκκλησιαστικού έτους, ως αφετηρία της επίγειας διδασκαλίας του Χριστού και ως ανανέωση της καρποφορίας της γης. Όλα τα παραπάνω σχετίζονται με τον χρόνο και τον χώρο ως δημιουργίες και μέσα του Θεού για τον επαναπροσδιορισμό του ανθρώπου στο φυσικό του περιβάλλον. Η παρούσα διπλωματική εργασία, που ονομάζεται «Η εορτή της Ινδίκτου στη βυζαντινή και μεταβυζαντινή μελοποιία», πραγματεύεται την δημιουργία και εξέλιξη της εορτής της Ινδίκτου και την αναλύει ως προς τη θεολογική της υπόσταση αλλά και την υμνογραφική της επένδυση. Επίσης προσπαθεί να εντοπίσει όλες τις παραμέτρους ως προς τις τυπικές διατάξεις που διέπουν την εορτή αυτή. Στο τελευταίο αλλά μεγαλύτερο και σημαντικότερο μέρος της η διατριβή αυτή καταλήγει σε μία μουσικολογική συγκριτική μελέτη συνθέσεων ενός δοξαστικού της ημέρας στην παλιά παρασημαντική από δύο σημαντικούς μελοποιούς, τον Γερμανό Νέων Πατρών και τον Χρυσάφη το νέο, και στην εξήγηση αυτών από τον Χουρμούζιο Χαρτοφύλακα.
description: The Orthodox Church celebrates the Feast of Indictum as the beginning of the ecclesiastical year, as the starting point of the earthly teaching of Christ and the renewal of the fruitfulness of the earth. All of the above relate to time and space as creations and means of God to redefine man in his natural environment. This dissertation, which called “The Feast of Indictum in the Byzantine and Late Byzantine Composing”, deals with the creation and evolution of the feast of Indictum and analyzes it in terms of its theological hypostasis and its hymnographic investment. It also tries to identify all the parameters regarding the formal provisions governing this feast. In the last but larger and most important part of this dissertation is presented a musicological comparative study of compositions of a Doxastikon in the old notation by two important musicians, the Germanos of New Patras and Chrysafi the new, and to their explanation by Hourmousios the Chartophylax.

description: We consider a mixture of one neutral and two oppositely charged types of molecules confined to a surface. Using analytical techniques and molecular dynamics simulations, we construct the phase diagram of the system and exhibit the coexistence between a patterned solid phase and a charge-dilute phase. The patterns in the solid phase arise from competition between short-range immiscibility and long-range electrostatic attractions between the charged species. The coexistence between phases leads to observations of stable patterned domains immersed in a neutral matrix background.

description: Η ενθογένεση και η δημιουργία του κράτους της Νιγηρίας ξεκίνησαν σε διαφορετικές χρονικές στιγμές. Η μορφή και έκταση των συνόρων της σημερινής Νιγηρίας διαμορφώθηκαν από τις αρχές του 20ου αιώνα και είναι ακέραια μέχρι και σήμερα. Ως πρώην βρετανική αποικία η Νιγηρία ήταν ένα ανομοιογενές κράτος όσο αφορά τον πληθυσμό της. Αποτελούνταν από εκατοντάδες διαφορετικές φυλές, οι οποίες μεταξύ τους χωρίζονταν κυρίως γεωγραφικά και θρησκευτικά. Το ομοσπονδιακό σύστημα διακυβέρνησης που εφαρμόστηκε από την αποικιακή περίοδο διατηρήθηκε και στην περίοδο της ανεξαρτησίας της Νιγηρίας καθώς ήταν το καταλληλότερο μέσο για να ξεπεραστούν οι φυλετικές διαφορές και να ενισχυθεί η εθνική ενότητα. Χρειάστηκε χρόνος, μεγάλη προσπάθεια και αρκετές αποτυχίες στην πορεία έτσι ώστε επιτευχθεί η εθνική ενότητα. Ο στρατιωτικός παράγοντας συνέβαλε καθοριστικά στην ισχυροποίηση της εθνικής συνείδησης. Οι πολυάριθμές και μακρόβιες στρατιωτικές δικτατορίες αποτέλεσαν ενοποιητικό παράγοντα, αφού οι νιγηριανοί πολίτες ανεξαιρέτου φυλετικής καταγωγής και θρησκευτικής προτίμησης αγωνίστηκαν για την αποκατάσταση της δημοκρατίας στην χώρα. Οι δεκαετίες στρατιωτικής διακυβέρνησης έδωσαν την ευκαιρία στους προηγούμενους δικτάτορες να νομιμοποιηθούν στις συνειδήσεις των κατοίκων. Η παραπάνω κίνηση είχε ως συνέπεια ακόμη και μετά την αποκατάσταση της δημοκρατίας οι πρώην στρατιωτικοί να μονοπωλούν την προεδρική εξουσία.
description: The ethnogenesis and creation of the state of Nigeria began at different times. The form and extent of the borders of today's Nigeria formed at the beginning of the 20th century and are still intact until today. As a former British colony, Nigeria was a heterogeneous state concerning its population. They consisted of hundreds of different clans, which were mainly geographically and religiously divided. The federal system of governance which was enforced since the colonial era was maintained after the Nigerian independence as it was the most appropriate and appealing mean of overcoming and tackling clan differences, meanwhile strengthening national unity. It took time, a lot of effort and several failures along the long and difficult road to achieve national unity. The military factor has contributed decisively to the strengthening of national consciousness. Numerous and long-standing military dictatorships formed a unifying element, since Nigerian citizens of every clan and racial descent and religious preference fought for the restoration of democracy in the country. Decades of military rule have given the opportunity to previous dictators to legitimize in the consciences of the inhabitants. Consequently, even after the restoration of democracy that the former military monopolized the presidential power.
New Bell inequalities for the singlet state: Going beyond the Grothendieck bound

description: Contemporary versions of Bell's argument against local hidden variable (LHV) theories are based on the Clauser Horne Shimony and Holt (CHSH) inequality, and various attempts to generalize it. The amount of violation of these inequalities cannot exceed the bound set by the Grothendieck constants. However, if we go back to the original derivation by Bell, and use the perfect anti-correlation embodied in the singlet spin state, we can go beyond these bounds. In this paper we derive two-particle Bell inequalities for traceless two-outcome observables, whose violation in the singlet spin state go beyond the Grothendieck constants both for the two and three dimensional cases. Moreover, creating a higher dimensional analog of perfect correlations, and applying a recent result of Alon and his associates (Invent. Math. 163 499 (2006)) we prove that there are two-particle Bell inequalities for traceless two-outcome observables whose violation increases to infinity as the dimension and number of measurements grow. Technically these result are possible because perfect correlations (or anti-correlations) allow us to transport the indices of the inequality from the edges of a bipartite graph to those of the complete graph. Finally, it is shown how to apply these results to mixed Werner states, provided that the noise does not exceed 20%.

description: We investigate triangle UD ladder integrals in the position space. The investigation is necessary to find an all-order in loop solution for an auxiliary Lcc correlator in Wess-Zumino-Landau gauge of the maximally supersymmetric Yang-Mills theory and to present correlators of dressed mean gluons in terms of it in all loops. We show that triangle UD ladder diagrams in the position space can be expressed in terms of the same UD functions Phi^(L) in terms of which they were represented in the momentum space, for an arbitrary number of rungs.
