description: Σκοπός της διατριβής ήταν η μελέτη της σύγκρουσης δικαιωμάτων και συγκεκριμένα αυτών της θρησκευτικής ελευθερίας και της ελευθερίας της τέχνης, όπως αυτή αποδόθηκε από το Ευρωπαϊκό Δικαστήριο Ανθρωπίνων Δικαιωμάτων. Αρχικά, εξετάσαμε το θεωρητικό υπόβαθρο του νομικού πλαισίου της Ευρωπαϊκής Συνθήκης Ανθρωπίνων Δικαιωμάτων. Συγκεκριμένα προσεγγίσαμε και αναλύσαμε το περιεχόμενο των διατάξεων της Ευρωπαϊκής Σύμβασης Ανθρωπίνων Δικαιωμάτων. Στη συνέχεια δώσαμε έμφαση στους θεμιτούς περιορισμούς των δύο ελευθεριών, όπως αυτοί προβλέπονται στη Σύμβαση, διανθίζοντάς τους παράλληλα με νομολογιακά παραδείγματα. Στο δεύτερο μέρος της διατριβής, αναφερθήκαμε αναλυτικά στη σύγκρουση των δύο ελευθεριών, όπως αυτή εκδηλώθηκε σε κράτη-μέλη του Συμβουλίου της Ευρώπης. Επίσης, κεντρικό σημείο της διατριβής αποτέλεσαν οι λύσεις που κλήθηκε να δώσει το Ευρωπαϊκό Δικαστήριο Ανθρωπίνων Δικαιωμάτων, προκειμένου να άρει τη σύγκρουση αυτή. Eπιπλέον ασχοληθήκαμε με τη κριτική των εν λόγω αποφάσεων, παρουσιάζοντας συγχρόνως διαφορετικές προσεγγίσεις επίλυσης των υποθέσεων.
description: The aim of the present thesis was the study of conflict of rights and particularly those of freedom of religion and freedom of art, as the European Court of Human rights expressed them. Firstly, we examined the theoretical basis of the legal frame of European Convention of Human Rights. Specifically, we approached and analyzed the content of articles of European Convention of Human Rights. Then we emphasized the legal restrictions of the two freedoms, as the Convention defines them, enriching them with jurisprudential examples. In the second part of thesis, we examined the conflict of two freedoms, as it occurred to the members of the European Council. Furthermore, a central part of thesis was the solutions that the European Court gave, so as to solve the conflict. Additionally, we focused on the criticism of the decisions, presenting parallel different approaches of solutions in the cases.

description: To investigate the magnetic properties of SmFe$_{12}$, we construct an effective spin model, where magnetic moments, crystal field (CF) parameters, and exchange fields at 0 K are determined by first principles. Finite temperature magnetic properties are investigated by using this model. We further develop an analytical method with strong mixing of states with different quantum number of angular momentum $J$ ($J$-mixing), which is caused by strong exchange field acting on spin component of 4$f$ electrons. Comparing our analytical results with those calculated by Boltzmann statistics, we clarify that the previous analytical studies for Sm transition metal compounds over-estimate the $J$-mixing effects. The present method enables us to make quantitative analysis of temperature dependence of magnetic anisotropy (MA) with high-reliability. The analytical method with model approximations reveals that the $J$-mixing caused by exchange field increases spin angular momentum, which enhances the absolute value of orbital angular momentum and MA constants via spin-orbit interaction. It is also clarified that these J-mixing effects remain even above room temperature. Magnetization of SmFe$_{12}$ shows peculiar field dependence known as first-order magnetization process (FOMP), where the magnetization shows an abrupt change at certain magnetic field. The result of the analysis shows that the origin of FOMP is attributed to competitive MA constants between positive $K_1$ and negative $K_2$. The sign of $K_{1(2)}$ appears due to an increase in CF potential denoted by the parameter $A_2^0\langle r^2\rangle$ ($A_4^0\langle r^4\rangle$) caused by hybridization between 3$d$-electrons of Fe on 8$i$ (8$j$) site and 5$d$ and 6$p$ valence electrons on Sm site. It is verified that the requirement for the appearance of FOMP is given as $-K_2

description: In quantum mechanics, the process of measurement is a subtle interplay between extraction of information and disturbance of the state of the quantum system. A quantum non-demolition (QND) measurement minimizes this disturbance by using a particular system - detector interaction which preserves the eigenstates of a suitable operator of the quantum system. This leads to an ideal projective measurement. We present experiments in which we perform two consecutive measurements on a quantum two -level system, a superconducting flux qubit, by probing the hysteretic behaviour of a coupled nonlinear resonator. The large correlation between the results of the two measurements demonstrates the QND nature of the readout method. The fact that a QND measurement is possible for superconducting qubits strengthens the notion that these fabricated mesoscopic systems are to be regarded as fundamental quantum objects. Our results are also relevant for quantum information processing, where projective measurements are used for protocols like state preparation and error correction.

Mechanical model of a boundary layer for the parallel tracks of kilohertz quasi-periodic oscillations in accreting neutron stars

description: Kilohertz-scale quasi-periodic oscillations (kHz QPOs) are a distinct feature of the variability of neutron star low-mass X-ray binaries. Among all the variability modes, they are especially interesting as a probe for the innermost parts of the accretion flow, including the accretion boundary layer (BL) on the surface of the neutron star. All the existing models of kHz QPOs explain only part of their rich phenomenology. Here, we show that some of their properties may be explained by a very simple model of the BL that is spun up by accreting rapidly rotating matter from the disk and spun down by the interaction with the neutron star. In particular, if the characteristic time scales for the mass and the angular momentum transfer from the BL to the star are of the same order of magnitude, our model naturally reproduces the so-called parallel tracks effect, when the QPO frequency is correlated with luminosity at time scales of hours but becomes uncorrelated at time scales of days. The closeness of the two time scales responsible for mass and angular momentum exchange between the BL and the star is an expected outcome of the radial structure of the BL.

description: Ρατσισμός είναι η αντίληψη πως όλοι οι άνθρωποι μεταξύ τους δεν είναι ίσοι, εξαιτίας της διαφορετικότητάς τους. Είναι μια συμπεριφορά που παρατηρείται στις περισσότερες κοινωνίες. Αποτελεί διαχρονικό φαινόμενο και δυστυχώς, τα περιστατικά ρατσιστικής βίας και ρατσιστικού λόγου σε βάρος συνανθρώπων μας πληθαίνουν. Εκτός από το φαινόμενο του ρατσισμού, παρουσιάζονται και άλλα φαινόμενα όπως αυτό του εθνικισμού και της ξενοφοβίας, τα οποία, όμως, δεν ταυτίζονται με την έννοια «ρατσισμός». Στόχος της παρούσας διπλωματικής εργασίας είναι να παρουσιασθεί το νομικό πλαίσιο μέσα στο οποίο αντιμετωπίζεται το φαινόμενου του ρατσισμού στην ελληνική έννομη τάξη, καθώς και η αποτελεσματικότητά του. Προαπαιτούμενο αυτής της παρουσίασης είναι η εξέταση του διεθνούς και ευρωπαϊκού πλαισίου κατά του ρατσισμού, καθώς η χώρα μας δεσμεύεται από τις επιταγές του. Η ποινικοποίηση, ωστόσο, του ρατσιστικού λόγου από τον Έλληνα νομοθέτη αποτελεί οριακό σημείο σύγκρουσης μεταξύ δύο θεμελιωδών αρχών του δημοκρατικού πολιτεύματος: της απαγόρευσης των διακρίσεων και της ελευθερίας του λόγου. Ιδιαίτερο ενδιαφέρον παρουσιάζει ο τρόπος με τον οποίο τα ελληνικά δικαστήρια αντιμετώπισαν στην πράξη την σύγκρουση αυτή (ΟλΑΠ 3/2010).
description: Racism is the concept that all people are not equal because of their differences. It is a behavior observed in the majority of societies. It is a timeless phenomenon and unfortunately incidents of racist behavior and racist speech have increased. Apart from racism, there are as well other phenomena as nationalism and xenophobia, which, however, cannot be considered identical to the term 'racism'. The subject of this master thesis is to present the legal context within which the phenomenon of racism is treated in the Greek legislation system as well as its effectiveness. Prerequisite of this presentation is to examine the international and European framework against racism, as our country is bound by these requirements. The criminalization, however, of the racist speech imposed by the Greek legislator is a marginal point of collision between two of the fundamental principles of democracy: non-discrimination and freedom of speech. The way the Greek courts encountered in practice this conflict is also of particular interest.

description: Modular equations occur in number theory, but it is less known that such equations also occur in the study of deformation properties of quasiconformal mappings. The authors study two important plane quasiconformal distortion functions, obtaining monotonicity and convexity properties, and finding sharp bounds for them. Applications are provided that relate to the quasiconformal Schwarz Lemma and to Schottky's Theorem. These results also yield new bounds for singular values of complete elliptic integrals.

description: Action Recognition from visual content is a highly active research field in Computer Science and more particular in Machine Learning area. This field is applied in many areas such as smart surveillance, biometrics, and robotics by emphasize in human-computer interaction. Recently research community is focus in Deep Learning techniques and application, due to state-of-the-art results in Computer Vision and Multimedia Analysis fields. In this work a new method for human action recognition is proposed. This method is based in Deep Learning techniques such as Autoencoders and Neural Networks Classifiers. The proposed method is view invariant which is a very important for ``real-world'' problems. We try to encode the temporal information in a video in order to simplify the problem for the subsequent classification.

description: Divergent values and. approaches to land and resource use and fur conservation created conflicts between aboriginal and non- aboriginal peoples which have remained largely hidden in historical records. This study of the compulsory trap line registration system implemented in British Columbia in 1925 examines these conflicts; the jurisdictional arid administrative issues related, to fur conservation that contributed, to the disputes; and the First Nations objections to fur management schemes that validated white appropriation of traditional lands and restricted traditional vocations and access to important sources of food.' supplies. Although First Nations people spoke persuasively about aboriginal rights and justice, their voices remained largely unheard and. unheeded. Legally disempowered and without political support, First Nation's people were marginalized, removed from lands they had occupied and used, since 'time immemorial.'

description: With the major increase in the volume of the spectroscopic line lists needed to perform accurate radiative transfer calculations, disseminating accurate radiative data has become almost as much a challenge as computing it. Considering that many planetary science applications are only looking for heating rates or mid-to-low resolution spectra, any approach enabling such computations in an accurate and flexible way at a fraction of the computing and storage costs is highly valuable. For many of these reasons, the correlated-k approach has become very popular. Its major weakness has been the lack of ways to adapt the spectral grid/resolution of precomputed k-coefficients, making it difficult to distribute a generic database suited for many different applications. Currently, most users still need to have access to a line-by-line transfer code with the relevant line lists or high-resolution cross sections to compute k-coefficient tables at the desired resolution. In this work, we demonstrate that precomputed k-coefficients can be binned to a lower spectral resolution without any additional assumptions, and show how this can be done in practice. We then show that this binning procedure does not introduce any significant loss in accuracy. Along the way, we quantify how such an approach compares very favorably with the sampled cross section approach. This opens up a new avenue to deliver accurate radiative transfer data by providing mid-resolution k-coefficient tables to users who can later tailor those tables to their needs on the fly. To help with this final step, we briefly present Exo_k, an open-access, open-source Python library designed to handle, tailor, and use many different formats of k-coefficient and cross-section tables in an easy and computationally efficient way.

description: The well known (3+1) decomposition of Thorne and Macdonald is invoked to write down the Einstein-Maxwell equations generalised to (d+1) dimensions and also to formulate the plasma equations in a flat FRW like spacetime in higher dimensions (HD). Assuming an equation of state for the background metric we find solutions as also dispersion relations in different regimes of the universe in a unified manner both for magnetised(un) cold plasma. We find that for a free photon in expanding background we get maximum redshift in 4D spacetime, while for a particular dimension it is so in pre recombination era. Further wave propagation in magnetised plasma is possible for a restricted frequency range only, depending on the number of dimensions. Relevant to point out that unlike the special relativistic result this allowed range evolves with time. Interestingly the dielectric constant of the plasma media remains constant, not sharing the expansion of the background, which generalises a similar 4D result of Holcomb-Tajima in radiation background to the case of higher dimensions with cosmic matter obeying an equation of state . Further, analogous to the flat space static case we observe the phenomenon of Faraday rotation in higher dimensional case also.

The switching mechanisms of social network densification

description: Densification and sparsification of temporal networks are attributed to two fundamental mechanisms: a change in the population in the system and/or a change in the chances that nodes in the system are connected. In theory, each of these mechanisms generates a distinctive type of densification scaling, but in reality both types are generally mixed. Here, we develop a Bayesian statistical method to identify the extent to which each of these mechanisms is at play at a given point in time, taking the mixed densification scaling as input. We apply the method to networks of face-to-face interactions of individuals and reveal that the main mechanism that causes densification and sparsification occasionally switches, the frequency of which depending on the social context. The proposed method uncovers an inherent regime-switching property of network dynamics, which will provide a new insight into the mechanics behind evolving social interactions.

description: The stellar initial mass function (IMF) seems to be variable and not universal, as argued in the literature in the last three decades. Several relations among the low-mass end of the IMF slope and other stellar population, photometric or kinematic parameters of massive early-type galaxies (ETGs) have been proposed, but a consolidated agreement on a factual cause of the observed variations has not been reached yet. We investigate the relations between the IMF and other stellar population parameters in NGC 3311, the central galaxy of the Hydra I cluster. NGC 3311 is characterized by old and metal-rich stars, like other massive ETGs, but has unusual increasing stellar velocity dispersion and [$α/$Fe] profiles. We use spatially resolved MUSE observations to obtain stellar population properties using Bayesian full-spectrum fitting in the central part of NGC 3311 to compare the IMF slope against other stellar parameters with the goal of assessing their relations/dependencies. For NGC 3311, we unambiguously invalidate the previously observed direct correlation between the IMF slope and the local stellar velocity dispersion, confirming some doubts already raised in the literature. This relation may arise as a spatial coincidence only, between the region with the largest stellar velocity dispersion, with that where the oldest, $\textit{in situ}$ population is found and dominates. We also show robust evidence that the proposed IMF-metallicity relation is contaminated by the degeneracy between these two parameters. The tightest correlations we found are those between stellar age and IMF and between galactocentric radius and IMF. The variation of the IMF is not due to kinematical, dynamical, or global properties in NGC 3311. We speculate that IMF might be dwarf-dominated in the "red-nuggets" formed at high redshifts that ended up being the central cores of today's giant ellipticals. [Abridged]

Κατά την πρώτη φάση ανάλυσης ορίζονται οι εγκεφαλικοί ρυθμοί και μελετώνται τα φάσματα ισχύος. Στη συνέχεια δημιουργούνται οι γράφοι λειτουργικής συνδεσιμότητας και τα ελάχιστα ζευγνύοντα δέντρα τους. Έτσι μελετώνται τα χαρακτηριστικά των MSTs πριν και μετά την αναισθησία. Ακολούθως βρίσκοντας την απόσταση μεταξύ των MSTs εξετάζεται η διαχωρισιμότητα των 2 καταστάσεων. Με μια διαδικασία υποδειγματοποίησης εντοπίζεται το ενδιάμεσο MST σε κάθε κατάσταση και μελετάται η διαφορά της συνδεσιμότητας τους. Τέλος μελετάται η σχέση ανατομικής και λειτουργικής συνδεσιμότητας των 2 καταστάσεων. Τα αποτελέσματα δείχνουν μεγαλύτερη ενέργεια φάσματος ισχύος μετά την αναισθησία στις χαμηλές συχνότητες αλλά στις ψηλές συχνότητες συμβαίνει το αντίθετο. Σχεδόν σε όλα τα χαρακτηριστικά των MSTs η μεγαλύτερη διαφορά των 2 καταστάσεων παρατηρείται στη delta και alpha ζώνη συχνοτήτων. Στη delta και beta ζώνη συχνοτήτων τα MSTs των 2 καταστάσεων είναι πιο καλά διαχωρίσιμα. Στην alpha και gamma2 ζώνη συχνοτήτων οι 2 καταστάσεις ενδιάμεσων MSTs έχουν μεγαλύτερη διαφορά.
description: In the particular work, the brain activity during anesthesia in monkey, using ECoG is examined. The first part of the study consists of the definition of brain waves and the examination of the power spectrum. Then, the functional connectivity graphs and their minimum spanning trees are generated. Thus, the characteristics of MSTs before and after anesthesia are investigated. Then, finding the distance between the MSTs, the separability of the two states is examined. With a modeling process the centroid MST is found for every state and the difference of their connectivity is examined. Finally the relationship between anatomical and functional connectivity of the two states is studied. The results show that the power spectrum density after anesthesia is greater at low frequencies but it is the opposite at high frequencies. In delta and alpha frequency band the difference of the two states of MST’s features is greater. In delta and beta frequency band the MSTs of the two states are better separable. In alpha and gamma2 frequency band the difference of the two states of centroid MST is greater.

description: We have shown in a previous paper that two identical detectors with each fiducial mass of 0.27 megaton water, one in Kamioka and the other in Korea, which receive the (anti-) muon neutrino beam of 4 MW power from J-PARC facility have potential of determining the neutrino mass hierarchy and discovering CP violation by resolving the degeneracies associated with them. In this paper, we point out that the same setting has capability of resolving the θ_{23} octant degeneracy in region where sin^2 2θ_{23} \lsim 0.97 at 2 standard deviation confidence level even for very small values of θ_{13}. Altogether, it is demonstrated that one can solve all the eight-fold neutrino parameter degeneracies in situ by using the Tokai-to-Kamioka-Korea setting if θ_{13} is within reach by the next generation superbeam experiments. We also prove the property called ``decoupling between the degeneracies'', which is valid to first order in perturbation theory of the earth matter effect, that guarantees approximate independence between analyses to solve any one of the three different type of degeneracies.

How does Background Air Pressure Influence the Inner Edge of the Habitable Zone for Tidally Locked Planets in a 3D View?

description: We examine the effect of varying background N2 surface pressure (labelled as pN2) on the inner edge of the habitable zone for 1:1 tidally locked planets around M dwarfs, using the three-dimensional (3D) atmospheric general circulation model (AGCM) ExoCAM. In our experiments, the rotation period is fixed when varying the stellar flux, in order to more clearly isolate the role of pN2. We find that the stellar flux threshold for the runaway greenhouse is a non-monotonous function of pN2. This is due to the competing effects of five processes: pressure broadening, heat capacity, lapse rate, relative humidity, and clouds. These competing processes increase the complexity in predicting the location of the inner edge of the habitable zone. For a slow rotation orbit of 60 Earth days, the critical stellar flux for the runaway greenhouse onset is 1700--1750, 1900--1950, and 1750--1800 W m$^{-2}$ under 0.25, 1.0, and 4.0 bar of pN2, respectively, suggesting that the magnitude of the effect of pN2 is within ~13%. For a rapid rotation orbit, the effect of varying pN2 on the inner edge is smaller, within a range of ~7%. Moreover, we show that Rayleigh scattering effect as varying pN2 is unimportant for the inner edge due to the masking effect of cloud scattering and to the strong shortwave absorption by water vapor under hot climates. Future work using AGCMs having different cloud and convection schemes and cloud-resolving models having explicit cloud and convection are required to revise this problem.

 Type locality: Greenland.
 See: Fisher (1930: 60–61, pl. 30, figs. 1, 1a–c, 2, 2a–2d, pl. 32, figs. 3, 3a, pl. 35, figs. 1–3); A.M. Clark & Downey (1992: 441–442).
 Occurrence: circumpolar Arctic; in the Atlantic, from Labrador and Greenland south to George’s Bank (Fisher 1930, A.M. Clark & Downey 1992).
 Depth: 0–360 m (A.M. Clark & Downey 1992).
 Habitat: juveniles and small adults can be found on rocky substrates in shallow water, below lowest water of spring tides; large adults occupy cobble to sandy and muddy areas at greater depths (Rochette et al. 1994).
 Larval stage: brooding (Hamel & Mercier 1995).
 Remarks: Perrier (1896a) reported L. polaris (as Asterias polaris) from the Azorean rocky intertidal, which later Koehler (1924) re-identifed to Asterias rubens. Later references of this species to the archipelago were based on Perrier’s original report. Nonetheless, the sea surface temperatures in the Azores reach an average minimum of 14°C in the winter (Bashmachnikov et al. 2004) clearly providing an inhospitable environment far too warm to sustain a viable population of this Arctic species (see Hamel & Mercier 1995). The same conclusion can be reached on the possible presence of C. crispatus in the archipelago, i.e. it is unlikely that this stenothermal boreo-arctic species (see Shick et al. 1981) could maintain a viable population in the rocky shores of the Azores.

description: We investigate the possibility of tracking individual hydrogen micro-spheres from an internal pellet target. Such a method aims to provide the primary vertex of a reaction to within about 100 micrometres, without utilizing any detector response. Apart from background considerations the knowledge of the reaction vertex may be essential for the reconstruction of many physics channels. This is in particular true for the study of the Psi(3770) decay into D-mesons planned at the PANDA detector at the future FAIR facility. Here, the reconstruction of displaced vertices is especially difficult since neutral particles are involved. Studies with a pellet target at The Svedberg Laboratory, Uppsala, show the technical feasibility of a tracking system utilizing fast CCD line-scan cameras. Simulations for the reaction p-bar p to Psi(3770) to D+ D- prove the large impact such a system would have on the data taking and reconstruction at PANDA.

description: Context: The sub-Jovian or Neptunian desert is a previously-identified region of parameter space where there is a relative dearth of intermediate-mass planets at short orbital periods. Aims: We present the discovery of a new transiting planetary system within the Neptunian desert, NGTS-14. Methods: Transits of NGTS-14Ab were discovered in photometry from the Next Generation Transit Survey (NGTS). Follow-up transit photometry was conducted from several ground-based facilities, as well as extracted from TESS full-frame images. We combine radial velocities from the HARPS spectrograph with the photometry in a global analysis to determine the system parameters. Results: NGTS-14Ab has a radius about 30 per cent larger than that of Neptune ($0.444\pm0.030~\mathrm{R_{Jup}}$), and is around 70 per cent more massive than Neptune ($0.092 \pm 0.012~\mathrm{M_{Jup}}$). It transits the main-sequence K1 star, NGTS-14A, with a period of 3.54 days, just far enough to have maintained at least some of its primordial atmosphere. We have also identified a possible long-period stellar mass companion to the system, NGTS-14B, and we investigate the binarity of exoplanet host stars inside and outside the Neptunian desert using Gaia.

description: We present results of magnetisation and electron paramagnetic resonance experiments on the spin-dimer system BaCuSi2O6. Evidence indicates that the origin of anisotropic terms in the spin Hamiltonian is from magnetic dipolar interactions. Axial symmetry-breaking is on a very small energy scale of ~11 mK, confirming Bose Einstein condensation critical scaling over an extended temperature range in the vicinity of the quantum critical point.

Application of the single-cell gel electrophoresis (’COMET’) assay to lymphocytes exposed In Vitro to captan, a fungicide
Creators: name: Stuart, Gregory Roy
Publisher: name: University of British Columbia
Year: 2009

description: This thesis describes the assembly and validation of a relatively developed assay of genotoxicity, the single-cell gel electrophoresis ('comet') assay, and its application to the detection of D N A damage associated with the exposure to captan, a fungicide, in human cells. The comet assay system was assembled using commercially available laboratory and image processing equipment. To facilitate the analysis of digital images from the comet assay, software was developed that was based on the public-domain program N IH Image. The comet assay system was validated in vitro using human peripheral blood lymphocytes and a known genotoxic agent, hydrogen peroxide, previously shown to give a positive response in the comet assay. The results from these experiments confirmed that this assay is capable of providing sensitive quantitative measures of the extent of induced D N A damage. Investigations of the amount of damage present in untreated lymphocyte D N A from different donors were also conducted. Once the comet assay system was validated it was applied to a study of the genotoxic effects of an agricultural fungicide, captan, which is widely used in British Columbia and may pose a risk to human health through occupational exposures. Both technical and analytical grades of captan were examined in vitro in the comet assay, using human lymphocytes. It was demonstrated that the comet assay was capable of detecting D N A strand breaks caused by captan at 0.1 micromolar concentrations. This result represents an increase in sensitivity of greater than an order of magnitude for detecting D N A strand breaks caused by captan, when compared to techniques previously employed, such as alkaline sucrose sedimentation.
ALMA measures rapidly depleted molecular gas reservoirs in massive quiescent galaxies at z~1.5

description: We present ALMA CO(2-1) spectroscopy of 6 massive (log$_{10}$M$_{\rm{*}}/\rm{M}_\odot>$11.3) quiescent galaxies at $z\sim1.5$. These data represent the largest sample using CO emission to trace molecular gas in quiescent galaxies above $z>1$, achieving an average 3$σ$ sensitivity of M$_{\rm{H_{2}}}\sim10^{10}\rm{M}_\odot$. We detect one galaxy at 4$σ$ significance and place upper limits on the molecular gas reservoirs of the other 5, finding molecular gas mass fractions M$_{\rm{H_{2}}}$/M$_{\rm{*}}$=f$_{\rm{H_{2}}}<2-6$% (3$σ$ upper limits). This is 1-2 orders of magnitude lower than coeval star-forming galaxies at similar stellar mass, and comparable to galaxies at $z=0$ with similarly low sSFR. This indicates that their molecular gas reservoirs were rapidly and efficiently used up or destroyed, and that gas fractions are uniformly low ($12$ by $z\sim4$ that halt the accretion of baryons early in the Universe. Our data is consistent with a simple picture where galaxies truncate accretion and then consume the existing gas at or faster than typical main sequence rates. Alternatively, we cannot rule out that these galaxies reside in lower mass halos, and low gas fractions may instead reflect either stronger feedback, or more efficient gas consumption.

Security proof for QKD systems with threshold detectors

description: In this paper, we rigorously prove the intuition that in security proofs for BB84 one may regard an incoming signal to Bob as a qubit state. From this result, it follows that all security proofs for BB84 based on a virtual qubit entanglement distillation protocol, which was originally proposed by Lo and Chau [H.-K. Lo and H. F. Chau, Science 283, 2050 (1999)], and Shor and Preskill [P. W. Shor and J. Preskill, Phys. Rev. Lett. 85, 441 (2000)], are all valid even if Bob's actual apparatus cannot distill a qubit state explicitly. As a consequence, especially, the well-known result that a higher bit error rate of 20% can be tolerated for BB84 protocol by using two-way classical communications is still valid even when Bob uses threshold detectors. Using the same technique, we also prove the security of the Bennett-Brassard-Mermin 1992 (BBM92) protocol where Alice and Bob both use threshold detectors.

Για τους ανωτέρω λόγους διερευνάται η δυνατότητα προστασίας των προγραμμάτων η/υ με δίπλωμα ευρεσιτεχνίας, γίνεται προσπάθεια να διακριθούν τα προβλήματα που αντιμετωπίστηκαν, οι λύσεις που εφαρμόστηκαν και οι προτάσεις που διατυπώθηκαν για μελλοντική βελτίωση.
description: The aim of the present thesis is to discuss the rapidly evolving technology and the efforts of intellectual property law to evolve likewise in order to provide intellectual protection to the products of this technology. Specifically, the thesis deals with the patent protection of computer programs and aims to inform the lawyers about the practical aspects of software and encourage the engineers to explore the potential protection of their inventions. It is obvious that during the investigation for protecting a computer invention, cooperation between lawyers and engineers is necessary, a fact that means that both sides should understand technical and legal terms. Moreover, it is observed that the legal regime as for computer patents is controversial due to the complex nature of the computer programs and the continued development of information technology. Technology dominates internationally, with many industries around the world dealing with the acquisition and exploitation of the economic
