description: Σκοπός της παρούσας εργασίας είναι να προσεγγίσει τον δικαστικό έλεγχο της συνταγματικότητας των νόμων στην Ελλάδα και στη Γαλλία με αφορμή την τροποποίηση που επέφερε στο γαλλικό σύστημα η αναθεώρηση του γαλλικού Συντάγματος το 2008 και τον συνεχιζόμενο διάλογο περί τροποποίησης του ελληνικού συστήματος. Πρόκειται για δύο συστήματα που παρουσιάζουν ιδιαιτερότητες σε σχέση με το επικρατούν στην Ευρώπη σύστημα δικαστικού ελέγχου της συνταγματικότητας των νόμων. Γι' αυτό αρχικά αναλύονται οι λόγοι και οι συνθήκες διαμόρφωσης του γαλλικού συστήματος και ακολουθεί η περιγραφή των χαρακτηριστικών του διαμορφωθέντος μετά την τροποποίηση συστήματος. Με ανάλογο τρόπο αναλύονται και τα ιδιαίτερα χαρακτηριστικά και οι πυλώνες στήριξης και νομιμοποίησης του δικαστικού ελέγχου της συνταγματικότητας των νόμων στην Ελλάδα. Πόσο συγκλίνουν τα δύο συστήματα μετά την γαλλική αναθεώρηση; Τελικά ο άξονας της έρευνας μετατοπίζεται στο Κράτος Δικαίου και στις επιρροές που δέχεται ο πυρήνας του από την επελθούσα μεταβολή στη Γαλλία και την ενδεχόμενη αλλαγή στην Ελλάδα.
description: The aim of the present work is to approach the judicial review of the constitutionality of the law in Greece and in France, on the occasion of the modification that took place in the French system with the revision of French Constitution in 2008 and the continuing dialogue concerning the modification of the Greek system. These two systems present particularities in regard to the prevailing in Europe system of judicial review of the constitutionality of the law. First we analyze the reasons and the conditions of configuration of the French system and then we describe the characteristics of the new system. With similar way we analyze the particular characteristics and the pylons of legalisation of judicial review of the constitutionality of the law in Greece. How close are the two systems after the French constitutional revision? Finally the axis of the survey is shifted in the State of Law and in the influences on his core from the change in France and the potential change in Greece.

description: In this repository, there is an example of how the data-driven model is utilized to evaluate the turbulent heat fluxes from the RegIPSL model. You can find the 3-hour observational data at the Meteopole station (MTOPole_3Hrly_MLP-Features_ObservationalData_Cleaned.nc) and the RegIPSL simulation at the two nearest grid cells (MTOPole_RegIPSL_Data-GrdPt1_With_MLP-Features.nc and MTOPole_RegIPSL_Data-GrdPt2_With_MLP-Features.nc).  The script “Estimating_Statistically-Based_Fluxes.py” provides the statistically-based estimates of sensible and latent heat fluxes corresponding with each environment. Subsequently,  “Comparing_RegIPSL_With_ObsandMLP_byScatter.py” performs the comparison.

description: We investigate theoretically the electronic structure and transport for a two-level quantum wire with Rashba spin-orbit coupling (SOC) under the irradiation of an external laser field at low temperatures. The photon-induced transitions between SOC-splitted subbands with the same lateral confinement quantum numbers and between subbands with different confinement quantum number are expected. Using the method of equation of motion (EOM) for Keldysh nonequilibrium Green's functions (NGF), we examine the time-averaged density of states (DOS) and the spin polarized conductance for the system with photon polarization perpendicular to the wire direction. Through the analytical analysis and some numerical examples, the interplay effects of the external laser field and the Rashba SOC on both the DOS and the conductance of the system are demonstrated and discussed. It is found that the external laser field can adjust the spin polarization rate and the transport of the quantum wire system with some proper Rashba SOC strengths.

A study of the relationships between road access, traffic safety and travel speed, and applications to access planning and speed zone design
Creators: name: Li, Jian
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates the impacts of highway access on traffic safety and traffic operation efficiency, and develops a model for planning access provisions. A comprehensive data base was created for the analyses by taking advantage of an existing photographic log of selected sectional highway information for one Canadian province. The data base includes information on access types, access density, traffic volume, speed limit, geometry, and accident records. A review of the existing traffic situation and an examination of some established relationships of access and accidents indicated a need to update current knowledge of the impact of highway access. Accident models are developed with particular emphasis on access and its combined effects with traffic volume and road geometric factors on highways. Furthermore, a conceptual hazard model is developed which includes traffic conflicts as additional information to extend the knowledge of access as a road hazard. The literature on access and traffic operation relationships is sparse, particularly on two-lane highways, perhaps because of the high cost of comprehensive data collection for this complex problem. Consequently the present investigation is restricted to the use of a surrogate of average travel speed to define access and speed relationship. In addition to the investigation of access impact, a framework for determining the optimal number of access points is formulated to help to set up access planning criteria. The optimization process is the application of the defined relationships between access and traffic safety and operations in highway planning and design. The process minimizes the total social cost as an integer nonlinear programming problem, solved by piecewise approximation. Finally, the relevant issues of access and speed zone design are addressed, in which particular attention is given to deriving speed transition zone length. The derived accident models show that accesses are major contributing factors of accidents on all types of highways. In some situations, the combined effects of access and geometric factors undermine further the safety level. The analysis for two-lane highway indicates that non-linear relationships may exist between accesses and travel speed. The derived optimization framework for planning access provisions provides a quantitative base for functional classification of roads. In traffic control design, a procedure of speed zone design is outlined with consideration of access provisions.

description: We explore the possible values of the $μ\to e γ$ branching ratio, $\text{BR}(μ\rightarrow eγ)$, and the electron dipole moment (eEDM), $d_e$, in no-scale SU(5) super-GUT models with the boundary conditions that soft supersymmetry-breaking matter scalar masses vanish at some high input scale, $M_{\rm in}$, above the GUT scale, $M_{\rm GUT}$. We take into account the constraints from the cosmological cold dark matter density, $Ω_{CDM} h^2$, the Higgs mass, $M_h$, and the experimental lower limit on the lifetime for $p \to K^+ \bar ν$, the dominant proton decay mode in these super-GUT models. Reconciling this limit with $Ω_{CDM} h^2$ and $M_h$ requires the Higgs field responsible for the charge-2/3 quark masses to be twisted, and possibly also that responsible for the charge-1/3 and charged-lepton masses, with model-dependent soft supersymmetry-breaking masses. We consider six possible models for the super-GUT initial conditions, and two possible choices for quark flavor mixing, contrasting their predictions for proton decay with versions of the models in which mixing effects are neglected. We find that $τ\left(p\rightarrow K^+ \barν\right)$ may be accessible to the upcoming Hyper-Kamiokande experiment, whereas all the models predict $\text{BR}(μ\rightarrow eγ)$ and $d_e$ below the current and prospective future experimental sensitivities or both flavor choices, when the dark matter density, Higgs mass and current proton decay constraints are taken into account. However, there are limited regions with one of the flavor choices in two of the models where $μ\to e$ conversion on a heavy nucleus may be observable in the future. Our results indicate that there is no supersymmetric flavor problem in the class of no-scale models we consider.

Few-Shot Hyperspectral Image Classification With Unknown Classes Using Multitask Deep Learning

Publisher: name: arXiv
Year: 2020
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: Current hyperspectral image classification assumes that a predefined classification system is closed and complete, and there are no unknown or novel classes in the unseen data. However, this assumption may be too strict for the real world. Often, novel classes are overlooked when the classification system is constructed. The closed nature forces a model to assign a label given a new sample and may lead to overestimation of known land covers (e.g., crop area). To tackle this issue, we propose a multitask deep learning method that simultaneously conducts classification and reconstruction in the open world (named MDL4OW) where unknown classes may exist. The reconstructed data are compared with the original data; those failing to be reconstructed are considered unknown, based on the assumption that they are not well represented in the latent features due to the lack of labels. A threshold needs to be defined to separate the unknown and known classes; we propose two strategies based on the extreme value theory for few-shot and many-shot scenarios. The proposed method was tested on real-world hyperspectral images; state-of-the-art results were achieved, e.g., improving the overall accuracy by 4.94% for the Salinas data. By considering the existence of unknown classes in the open world, our method achieved more accurate hyperspectral image classification, especially under the few-shot context.

description: No abstracts are to be cited without prior reference to the author. In the paper MSY reference points of sprat are estimated in relation to pressure from cod (predation) and density dependence in sprat growth. The analysis is based on long-term stochastic simulations, in which density dependent growth and density dependent predation mortality of sprat are considered. The analysis indicates that estimates of MSY parameters and the equilibrium biomass and yield curves strongly depend on the way growth and natural mortality are considered in the analysis.

description: No abstracts are to be cited without prior reference to the author. Sustainable harvest refers to exploiting a resource so that it is not depleted or permanently damaged. Sustainability is often assessed in purely demographic terms. However, there is an increasing realization that looking at total numbers or biomass of individuals left behind may reveal only an incomplete picture of consequences of the harvest. Genetic composition of the individuals harvested and those left behind will typically differ; effects of such selective removals will accumulate over time and result in evolutionary change. In this paper we summarize the present knowledge about management implications of this fisheries-induced evolution. We first discuss the potential consequences of fisheries-induced evolution on maximum sustainable yield, reference points, quality of catch, and resilience, establishing the case that fisheries-induced evolution needs to be accounted for in truly sustainable management. We then outline harvest strategies and tactics that may be used to minimize unwanted evolutionary changes

description: Electrical current can be completely spin polarized in a class of materials known as half-metals, as a result of the coexistence of metallic nature for electrons with one spin orientation and insulating for electrons with the other. Such asymmetric electronic states for the different spins have been predicted for some ferromagnetic metals - for example, the Heusler compounds- and were first observed in a manganese perovskite. In view of the potential for use of this property in realizing spin-based electronics, substantial efforts have been made to search for half-metallic materials. However, organic materials have hardly been investigated in this context even though carbon-based nanostructures hold significant promise for future electronic device. Here we predict half-metallicity in nanometre-scale graphene ribbons by using first-principles calculations. We show that this phenomenon is realizable if in-plane homogeneous electric fields are applied across the zigzag-shaped edges of the graphene nanoribbons, and that their magnetic property can be controlled by the external electric fields. The results are not only of scientific interests in the interplay between electric fields and electronic spin degree of freedom in solids but may also open a new path to explore spintronics at nanometre scale, based on graphene.

description: We experimentally investigate the properties of radio-frequency-dressed potentials for Bose-Einstein condensates on atom chips. The three-dimensional potential forms a connected pair of parallel waveguides. We show that rf-dressed potentials are robust against the effect of small magnetic-field variations on the trap potential. Long-lived dipole oscillations of condensates induced in the rf-dressed potentials can be tuned to a remarkably low damping rate. We study a beam-splitter for Bose-Einstein condensates and show that a propagating condensate can be dynamically split in two vertically separated parts and guided along two paths. The effect of gravity on the potential can be tuned and compensated for using a rf-field gradient.

description: Gravitational lensing and black hole shadows are one of the strongest observational evidences to prove the existence of black holes in the universe. The gravitational lensing arises due to the deflection of light by the gravitational field of a gravitating body such as a black hole. Investigation of the shadow cast by a compact object as well as deflection of light around it may provide the useful information about physical nature of the particular compact object and other related aspects. In this paper, we study the deflection of light by a dual charged stringy black hole spacetime derived in dilaton-Maxwell gravity. The variation of deflection angle with the impact parameter for different values of electric and magnetic charges is studied. We also study the shadow of this black hole spacetime to obtain the radius of shadow cast by it. We have considered an optically thin emission disk around it and observed that there are not significant changes in the shadow cast by this black hole compared to well-known Schwarzschild black hole spacetime in GR.

description: Multiferroic tunnel junctions (MFTJs) have aroused significant interest due to their functional properties useful for non-volatile memory devices. So far, however, all the existing MFTJs have been based on perovskite-oxide heterostructures limited by a relatively high resistance-area (RA) product unfavorable for practical applications. Here, using first-principles calculations, we explore spin-dependent transport properties of van der Waals (vdW) MFTJs which consist of two-dimensional (2D) ferromagnetic FenGeTe2 (n = 3, 4, 5) electrodes and 2D ferroelectric In2Se3 barrier layers. We demonstrate that such FemGeTe2/In2Se3/FenGeTe2 (m, n = 3, 4, 5) MFTJs exhibit multiple non-volatile resistance states associated with different polarization orientation of the ferroelectric In2Se3 layer and magnetization alignment of the two ferromagnetic FenGeTe2 layers. We find a remarkably low RA product which makes the proposed vdW MFTJs superior to the conventional MFTJs in terms of their promise for non-volatile memory applications.

Recent Developments in Neutron Star Thermal Evolution Theories and Observation

description: Recent years have seen some significant progress in theoretical studies of physics of dense matter. Combined with the observational data now available from the successful launch of Chandra and XMM/Newton X-ray space missions as well as various lower-energy band observations, these developments now offer the hope for distinguishing various competing neutron star thermal evolution models. For instance, the latest theoretical and observational developments may already exclude both nucleon and kaon direct Urca cooling. In this way we can now have a realistic hope for determining various important properties, such as the composition, superfluidity, the equation of state and stellar radius. These developments should help us obtain deeper insight into the properties of dense matter.

description: We calculate the void probability function (VPF) in simulations of Lyman-$α$ emitters (LAEs) across a wide redshift range ($z=3.1,\ 4.5,\ 5.7,\ 6.6$). The VPF measures the zero-point correlation function (i.e. places devoid of galaxies) and naturally connects to higher order correlation functions while being computationally simple to calculate. We explore the Poissonian and systematic errors on the VPF, specify its accuracy as a function of average source density and the volume probed, and provide the appropriate size scales to measure the VPF. At small radii the accuracy of the VPF is limited by galaxy density, while at large radii the VPF is limited by the number of independent volumes probed. We also offer guidelines for understanding and quantifying the error in the VPF. We approximate the error in the VPF by using independent sub-volumes of the catalogs, after finding that jackknife statistics underestimate the uncertainty. We use the VPF to probe the strength of higher order correlation functions by measuring and examining the hierarchical scaling between the correlation functions using count-in-cells. The negative binomial model (NBM) has been shown to best describe the scaling between the two point correlation function and VPF for low-redshift galaxy observations. We further test the fit of the NBM by directly deriving the volume averaged two-point correlation function from the VPF and vice versa. We find the NBM best describes the $z=3.1, 4.5, 5.7$ simulated LAEs, with a 1$σ$ deviation from the model in the $z=6.6$ catalog. This suggests that LAEs show higher order clustering terms similar to those of normal low redshift galaxies.

description: Dirac showed that the existence of one magnetic pole in the universe could offer an explanation for the discrete nature of the electric charge. Magnetic poles appear naturally in most Grand Unified Theories. Their discovery would be of greatest importance for particle physics and cosmology. The intense experimental search carried thus far has not met with success. Moreover, if the monopoles are very massive their production is outside the range of present day facilities. A way out of this impasse would be if the monopoles bind to form monopolium, a monopole- antimonopole bound state, which is so strongly bound, that it has a relatively small mass. Under these circumstances it could be produced with present day facilities and the existence of monopoles could be indirectly proven. We study the feasibility of detecting monopolium in present and future accelerators.

Our analytical results give the exact joint distribution function of the Fubini-Study metric and the Berry curvature. We discuss relations to Levy stable distributions and compare our results to numerical simulations of random-matrix ensembles as well as electrons in a random magnetic field.

description: Factors such as non-uniform definitions of mortality, uncertainty in disease prevalence, and biased sampling complicate the quantification of fatality during an epidemic. Regardless of the employed fatality measure, the infected population and the number of infection-caused deaths need to be consistently estimated for comparing mortality across regions. We combine historical and current mortality data, a statistical testing model, and an SIR epidemic model, to improve estimation of mortality. We find that the average excess death across the entire US is 13$\%$ higher than the number of reported COVID-19 deaths. In some areas, such as New York City, the number of weekly deaths is about eight times higher than in previous years. Other countries such as Peru, Ecuador, Mexico, and Spain exhibit excess deaths significantly higher than their reported COVID-19 deaths. Conversely, we find negligible or negative excess deaths for part and all of 2020 for Denmark, Germany, and Norway.
Velocity structure in gravel rivers
Creators: name: Martin, Violeta
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates velocity profiles in high gradient rivers with rough beds. Experimental work was carried out in the Hydraulics Laboratory of The Department of Civil Engineering at the University of British Columbia. Velocity measurements were taken in the flume with variable slope (S=0.01 to 0.021) and the size of bed material was D5o=5.0 cm. An Acoustic Doppler Velocity (ADV) probe was used and the turbulent flow structure was examined. Velocities in all three directions were measured and Reynolds stresses have been calculated. Existing methods for determination of velocity profiles are based on the theory that was developed for smooth rigid boundaries and low gradient rivers. These theories lead to a logarithmic velocity profile. However, a limited number of previous studies have shown that the velocity profile in mountain rivers is non4ogarithmic and therefore the mean velocity can be under or overestimated. This study shows that the commonly used logarithmic law does not give the best results. Using a different approach to the existing theory, a new velocity profile equation was developed. In addition, the Froude number, flow rate and Manning's roughness coefficient n were calculated. These parameters show that high energy dissipation is produced by large roughness elements and the flow is slightly subcritical. When additional roughness elements were added to the model, the Froude number decreased and Manning's n increased. The equation developed herein has a reasonable fit with the measured data, but additional work is needed to determine the exact range of applicability. Some existing field measurements agree and some disagree with the present theory, therefore further field measurements with the same measuring equipment need to be made to investigate whether natural streams behave in a similar manner.

description: Git metadata contains rich information for developers to understand the overall context of a large software development project. Thus it can help new developers, managers, and testers understand the history of development without needing to dig into a large pile of unfamiliar source code. However, the current tools for Git visualization are not adequate to analyze and explore the metadata: They focus mainly on improving the usability of Git commands instead of on helping users understand the development history. Furthermore, they do not scale for large and complex Git commit graphs, which can play an important role in understanding the overall development history. In this paper, we present Githru, an interactive visual analytics system that enables developers to effectively understand the context of development history through the interactive exploration of Git metadata. We design an interactive visual encoding idiom to represent a large Git graph in a scalable manner while preserving the topological structures in the Git graph. To enable scalable exploration of a large Git commit graph, we propose novel techniques (graph reconstruction, clustering, and Context-Preserving Squash Merge (CSM) methods) to abstract a large-scale Git commit graph. Based on these Git commit graph abstraction techniques, Githru provides an interactive summary view to help users gain an overview of the development history and a comparison view in which users can compare different clusters of commits. The efficacy of Githru has been demonstrated by case studies with domain experts using real-world, in-house datasets from a large software development team at a major international IT company. A controlled user study with 12 developers comparing Githru to previous tools also confirms the effectiveness of Githru in terms of task completion time.

description: The properties of kaons and antikaons and their modification in isospin asymmetric nuclear matter are investigated using a chiral SU(3) model. These isospin dependent medium effects are important for asymmetric heavy ion collision experiments. In the present work, the medium modifications of the energies of the kaons and antikaons, within the asymmetric nuclear matter, arise due to the interactions of kaons and antikaons with the nucleons and scalar mesons. The values of the parameters in the model are obtained by fitting the saturation properties of nuclear matter and kaon-nucleon scattering lengths. The pion-nucleon scattering lengths are also calculated within the chiral effective model and compared with earlier results from the literature. The density dependence of the isospin asymmetry is seen to be appreciable for the kaon and antikaon optical potentials. This can be particularly relevant for the future accelerator facility FAIR at GSI, where experiments using neutron rich beams are planned to be used in the study of compressed baryonic matter.

description: Protein domains are evolutionarily and functionally independent protein structure units, and domain-domain interactions may be related to protein functions. Predicting assembled domain structures is thus an important part of protein structure prediction. Ab initiostructure assembly of domains is needed when each domain structure can be predicted reliably but there are no proper structure templates covering the whole protein. In this research, we have developed a domain assembly method called GalaxyDomDock that predicts the relative orientation of two domains. Based on the analysis that the inter-domain interactions and the inter-chain interactions are similar, we decided to apply an ab initioprotein-protein docking method, GalaxyTongDock, for the domain assembly problem. First, in GalaxyDomDock, up to 10,000 assembled domain structures were predicted by GalaxyTongDock with additional geometric consideration of the domain linker which effectively reduces the conformational space for docking. The predicted structures were further screened for domain connectabiliy by the given linker using Dijkstra’s algorithm. Lastly, structural redundancy of the remaining structures was removed by clustering dependent on the protein size. GalaxyDomDock showed better or comparable performance compared to AIDA and Rosetta domain assembly protocols on various categories of benchmark tests.

description: The Council of Europe has published the Manual for Relating Language Examinations to the Common European Framework of Reference for Languages (CEFR), in order to help the providers of examinations relate their tests to the CEFR. Among the tools available in the Manual are the CEFR Content Analysis Grids. This study attempts to use the CEFR Content Analysis Grid for Reading to analyse Reading Comprehension test tasks, in order to relate them to the CEFR. The analysis is based on the Reading section of the Certificate of Attainment in Greek (CAG), offered by the Centre for the Greek Language. We use the CEFR Grid to gather information about each task, text and item in the test by specifying their characteristics (e.g. text source, discourse type, item type, estimated difficulty level, etc.). Our aim is the familiarisation with the CEFR Content Analysis Grid for Reading, that is, familiarisation with parameters referred to in the Grid and application of the Grid’s dimensions to test tasks.

description: No abstracts are to be cited without prior reference to the author. Supplementing fish stock assessment with environmental indicators is the core of ecosystem‐based fisheries management. Indicator based approaches are important for fish populations that are strongly affected by climate‐induced changes in the environment, such as Baltic cod (Gadus morhua). Besides the effects of over‐fishing, reproductive success is a crucial process in cod population dynamics; hence, indicators that reliably contribute to forecast recruitment are candidates for integrated advice. Our study focuses on the identification of potential environmental indicators for cod recruitment success, including the setting of thresholds discriminating between good and bad environmental conditions for recruitment. The present study shows that (i) biotic and abiotic indicators explain variation in recruitment success of Eastern Baltic cod (BE) after accounting for the effect of spawning stock size, and that for this case study (ii) spatially explicit indicators and thresholds must be considered. Here we show that depending on stock and environmental conditions, thresholds are inevitable and essential tools in supporting assessment‐model based stock advice for predicting recruitment success and providing first steps towards ecosystem‐based fisheries management.

description: The 21-cm signal from the Cosmic Dawn (CD) is likely to contain large fluctuations, with the most extreme astrophysical models on the verge of being ruled out by observations from radio interferometers. It is therefore vital that we understand not only the astrophysical processes governing this signal, but also other inherent processes impacting the signal itself, and in particular line-of-sight effects. Using our suite of fully numerical radiative transfer simulations, we investigate the impact on the redshifted 21-cm from the CD from one of these processes, namely the redshift-space distortions (RSDs). When RSDs are added, the resulting boost to the power spectra makes the signal more detectable for our models at all redshifts, further strengthening hopes that a power spectra measurement of the CD will be possible. RSDs lead to anisotropy in the signal at the beginning and end of the CD, but not while X-ray heating is underway. The inclusion of RSDs, however, decreases detectability of the non-Gaussianity of fluctuations from inhomogeneous X-ray heating measured by the skewness and kurtosis. On the other hand, mock observations created from all our simulations that include telescope noise corresponding to 1000 h observation with the Square Kilometre Array telescope show that we may be able image the CD for all heating models considered and suggest RSDs dramatically boost fluctuations coming from the inhomogeneous Ly-$α$ background.
