description: The trace set of a Fuchsian group $Γ$ ist the set of length of closed geodesics in the surface $Γ\backslash \mathbb{H}$. Luo and Sarnak showed that the trace set of a cofinite arithmetic Fuchsian group satisfies the bounded clustering property. Sarnak then conjectured that the B-C property actually characterizes arithmetic Fuchsian groups. Schmutz stated the even stronger conjecture that a cofinite Fuchsian group is arithmetic if its trace set has linear growth. He proposed a proof of this conjecture in the case when the group $Γ$ contains at least one parabolic element, but unfortunately this proof contains a gap. In the present paper we point out this gap and we prove Sarnak's conjecture under the assumption that the Fuchsian group $Γ$ contains parabolic elements.

description: We discuss the relationship between the cycle probabilities in the path-integral representation of the ideal Bose gas, off-diagonal long-range order, and Bose--Einstein condensation. Starting from the Landsberg recursion relation for the canonic partition function, we use elementary considerations to show that in a box of size L^3 the sum of the cycle probabilities of length k >> L^2 equals the off-diagonal long-range order parameter in the thermodynamic limit. For arbitrary systems of ideal bosons, the integer derivative of the cycle probabilities is related to the probability of condensing k bosons. We use this relation to derive the precise form of the π_k in the thermodynamic limit. We also determine the function π_k for arbitrary systems. Furthermore we use the cycle probabilities to compute the probability distribution of the maximum-length cycles both at T=0, where the ideal Bose gas reduces to the study of random permutations, and at finite temperature. We close with comments on the cycle probabilities in interacting Bose gases.

I focus on materials stacks, quantum dot architectures, bandstructure properties and qualifiers for disorder from electrical transport. This brief note is far from being exhaustive and should be considered a first introduction to the materials challenges and opportunities towards a larger spin qubit quantum processor.

description: Video super-resolution (VSR) aims to reconstruct a sequence of high-resolution (HR) images from their corresponding low-resolution (LR) versions. Traditionally, solving a VSR problem has been based on iterative algorithms that can exploit prior knowledge on image formation and assumptions on the motion. However, these classical methods struggle at incorporating complex statistics from natural images. Furthermore, VSR has recently benefited from the improvement brought by deep learning (DL) algorithms. These techniques can efficiently learn spatial patterns from large collections of images. Yet, they fail to incorporate some knowledge about the image formation model, which limits their flexibility. Unrolled optimization algorithms, developed for inverse problems resolution, allow to include prior information into deep learning architectures. They have been used mainly for single image restoration tasks. Adapting an unrolled neural network structure can bring the following benefits. First, this may increase performance of the super-resolution task. Then, this gives neural networks better interpretability. Finally, this allows flexibility in learning a single model to nonblindly deal with multiple degradations. In this paper, we propose a new VSR neural network based on unrolled optimization techniques and discuss its performance.

description: To evaluate and compare the effectiveness and quality of standard face-to-face and teleaudiology hearing aid fitting follow-up consultations and blended services for adult hearing aid users. Fifty-six participants were randomly allocated to two equal groups, with equal numbers of new and experienced users. One standard and one teleaudiology follow-up consultation were delivered by an audiologist, the latter assisted by a facilitator. The order was reversed for the second group. Outcome measurement tools were applied to assess aspects of participants’ communication, fitting (physical, sensorial), quality of life, and service. Cross-sectional and longitudinal outcomes were analysed. Most participants presented with moderate, sloping, and symmetrical sensorineural hearing loss. The duration of teleaudiology (42.96 ± 2.73 min) was equivalent to face-to-face consultations (41.25 ± 2.61 min). All modes of service delivery significantly improved outcomes for communication, fitting, and quality of life (p > 0.05). Satisfaction for both consultation modes was high, although significantly greater with standard consultations. The mode and order of delivery of the consultations did not influence the outcomes. Teleaudiology hearing aid follow-up consultations can deliver significant improvements, and do not differ from standard consultations. Blended services also deliver significant improvements. Satisfaction can be negatively impacted by technical or human-related issues.

description: Parents frequently experience challenges implementing daily routines important for consistent hearing aid management. Education that supports parents in learning new information and gaining confidence is essential for intervention success. We conducted a pilot study to test an eHealth program to determine if we could implement the program with adherence and affect important behavioural outcomes compared to treatment as usual. Randomised controlled trial. Parents of children birth to 42 months who use hearing aids. Eighty-two parents were randomly assigned to the intervention or treatment-as-usual group. Four parents assigned to the intervention group did not continue after baseline testing. The intervention was delivered successfully with low drop out (10%), high session completion (97%), and high program adherence. The intervention conditions showed significantly greater gains over time for knowledge, confidence, perceptions, and monitoring related to hearing aid management. Significant differences between groups were not observed for hearing aid use time. We found that we could successfully implement this eHealth program and that it benefitted the participants in terms of knowledge and confidence with skills important for hearing aid management. Future research is needed to determine how to roll programs like this out on a larger scale.

We propose a new approach, based on Papapetrou multipole expansion, that provides a new equation for the motion of a test particle. We show how this equation provides right couplings and does not generate huge massive modes.

BREVE NOTA SULLE ATTESTAZIONI DI SIGILLATA AFRICANA A TROINA (EN)

description: Il presente contributo illustra i risultati preliminari derivanti dallo studio degli esemplari di ceramica sigillata africana rivenuti a Troina (EN), nella fascia meridionale dei Monti Nebrodi, nel corso delle indagini archeologiche svolte tra gli anni Settanta e Novanta sul versante meridionale della Rocca di Troina, dove si trovano i resti della città antica. Il vasellame di produzione africana qui attestato, databile tra il I e il V secolo d.C., è riconducibile alle principali produzioni esportate nell’isola, con netta prevalenza di manufatti di prima (sigillata africana A) e tarda età imperiale (sigillata africana D, C/D, e F), trovando riscontro con i dati finora a disposizione dai coevi contesti della Sicilia interna. 


This paper shows the preliminary results from the study of African Red Slip Ware (or ‘ceramica sigillata africana’) fragments found in Troina (EN), on the southern part of Nebrodi Mountains, during the archaeological research carried out between the Seventies and the Nineties on the southern slope of the Rocca di Troina, where the remains of the ancient city are located. The African Red Slip Ware fragments here attested, dating from 1st to 5th century AD, were produced in the main workshops that exported pottery in Sicily, especially products made during the Early (“sigillata africana A”) and Late Imperial Age (“sigillata africana D”, “C/D” and “F”). They can be also compared to the data available so far from the contemporary contexts of inland Sicily.

Metastable phases and "metastable" phase diagrams

description: The work discusses specifics of phase transitions for metastable states of substances. The objects of condensed media physics are primarily equilibrium states of substances with metastable phases viewed as an exception, while the overwhelming majority of organic substances investigated in chemistry are metastable. It turns out that at normal pressure many of simple molecular compounds based on light elements (these include: most hydrocarbons; nitrogen oxides, hydrates, and carbides; carbon oxide (CO); alcohols, glycerin etc) are metastable substances too, i.e. they do not match the Gibbs' free energy minimum for a given chemical composition. At moderate temperatures and pressures, the phase transitions for given metastable phases throughout the entire experimentally accessible time range are reversible with the equilibrium thermodynamics laws obeyed. At sufficiently high pressures (1-10 GPa), most of molecular phases irreversibly transform to more energy efficient polymerized phases, both stable and metastable. These transformations are not consistent with the equality of the Gibbs' free energies between the phases before and after the transition, i.e. they are not phase transitions in "classical" meaning. The resulting polymeric phases at normal pressure can exist at temperatures above the melting one for the initial metastable molecular phase. Striking examples of such polymers are polyethylene and a polymerized modification of CO. Many of energy-intermediate polymeric phases can apparently be synthesized by the "classical" chemistry techniques at normal pressure.

The bacterial production of antimicrobial, cationic peptides and their effects on the outer membranes of Gram-negative bacteria
Creators: name: Piers, Kevin Lee
Publisher: name: University of British Columbia
Year: 2009

description: Natural polycationic antibiotic peptides have been found in many different species of animals and insects and shown to have broad antimicrobial activity. To permit further studies on these peptides, bacterial expression systems were developed. Attempts to express these peptides with an N-terminal signal sequence were unsuccessful due to the lability of the basic peptides. Therefore, different fusion protein systems were tested, including fusions to glutathione-S-transferase (GST) and Staphylococcus aureus protein A. For GST, fusions to the defensin, human neutrophil peptide 1 (HNP- 1), or a synthetic cecropin/melittin hybrid (CEME) were generally unstable if found in the soluble fraction of lysed cells, but were stable if found as insoluble inclusion bodies. In the course of these studies, we developed a novel method of purilring inclusion bodies, using the detergent octyl-polyoxyethylene, as well as establishing methods for preventing fusion protein proteolytic breakdown. Cationic peptides could be successfully released from the GST carrier protein with high efficiency by chemical means (cyanogen bromide digestion) and with low efficiency by enzymatic cleavage (using factor Xa). Fusions of protein A to cationic peptides were expressed in the culture supernatant of S. aureus clones and after affinity purification, CNBr digestion and column chromatography, pure cationic peptide was obtained. CEME produced by this procedure had the same amino acid content, amino acid sequence, gel electrophoretic mobility and antibacterial activity as CEME produced by protein chemical procedures. Three catiorilc peptides, CEME, CEMA and melittin, were all found to have a broad range of antibacterial activity at concentrations that were comparable to conventional antibiotics. All three were found to permeabiize the outer membrane of Pseudomorias aeruginosa and Enterobacter cloacae to lysozynie and the hydrophobic probe l-N-phenylnaphthylamine. CEMA permeabiized membranes at concentrations 2- to 5-fold lower than CEME and 20-fold lower than melittin. In some cases, it disrupted membranes better than polymyxin B, a known potent permeabilizer. CEMA also had the highest binding affinity for purified P. aeruginosa LPS and whole cells, although CEME and melittin also bound strongly. These data are discussed with special reference to the mechanism by which these peptides cross the outer membrane of Gram-negative bacteria. It is proposed that they utilize the self-promoted uptake pathway which has been suggested previously for other cationic antibiotics. As well, the potential for the use of cationic peptides as therapeutic antibiotics is discussed.

description: It is known that general relativity (GR) theory is not consistent with the latest observations. The modified gravity of GR known as $\mathrm{f(R)}$ where $\mathrm{R}$ is the Ricci scalar, is considered to be a good candidate for dealing with the anomalies present in classical GR. In this context, we study static rotating uncharged anti-de Sitter and de Sitter (AdS and dS) black holes (BHs) using $\mathrm{f(R)}$ theory without assuming any constraints on the Ricci scalar or on $\mathrm{f(R)}$. We derive BH solutions depend on the convolution function and deviate from the AdS/dS Schwarzschild BH solution of GR. Although the field equations have no dependence on the cosmological constant, the BHs are characterized by an effective cosmological constant that depends on the convolution function. The asymptotic form of this BH solution depends on the gravitational mass of the system and on extra terms that lead to BHs being different from GR BHs but to correspond to GR BHs under certain conditions. We also investigate how these extra terms are responsible for making the singularities of the invariants milder than those of the GR BHs. We study some physical properties of the BHs from the point of view of thermodynamics and show that there is an outer event horizon in addition to the inner Cauchy horizons. Among other things, we show that our BH solutions satisfy the first law of thermodynamics. To check the stability of these BHs we use the geodesic deviations and derive the stability conditions. Finally, using the odd-type mode it is shown that all the derived BHs are stable and have a radial speed equal to one.

description: The flat directions LLe and udd within the minimal supersymmetric Standard Model provide all the necessary ingredients for a successful inflation with the right amplitude of the scalar density perturbations, negligible gravity waves and the spectral tilt within 2σobserved range 0.92 \leq n_s \leq 1.0. In this paper we explore the available parameter space for inflation in conjunction with a thermal cold dark matter abundance within the minimal supergravity model. Remarkably for the inflaton, which is a combination of squarks and sleptons, there is a stau-neutralino coannihilation region below the inflaton mass 500 GeV for the observed density perturbations and the tilt of the spectrum. For such a low mass of the inflaton the LHC is capable of discovering the inflaton candidates within a short period of its operation. Inflation is also compatible with the focus point region which opens up for the inflaton masses above TeV. We show that embedding MSSM within SO(10) can naturally favor this region.

description: Basket trials examine the efficacy of a single intervention in multiple patient groups simultaneously. The assignment of patients to the subgroups, called baskets, is based on matching medical characteristics, which can result in small sample sizes within baskets that are also likely to differ. Sparse data complicate statistical inference. A number of Bayesian methods have been proposed in the literature that share information across baskets to increase statistical power. The power prior design incorporates data from all baskets using a weighted likelihood that shares information according to the similarity of the individual baskets. However, with unequal basket sizes, there is a risk of information loss, as the information of small baskets may be superimposed by that of larger baskets. We propose a new weighting method that accounts for differing sample sizes by limiting the amount of information shared between baskets. Considering unequally sized baskets, we systematically compare the power prior design with our new weighting method to existing methods as well as to other competing designs. The results of our simulation study show a superior performance of the power prior design with our new quantity limiting weights in reliably detecting an effect of the intervention under consideration.
The effect of AM noise on correlation phase noise measurements

Year: 2006
Subjects: subject: Instrumentation and Detectors (physics.ins-det)

description: We analyze the phase-noise measurement methods in which correlation and averaging is used to reject the background noise of the instrument. All the known methods make use of a mixer, used either as a saturated phase detector or as a linear synchronous detector. Unfortunately, AM noise is taken in through the power-to-dc-offset conversion mechanism that results from the mixer asymmetry. The measurement of some mixers indicates that the unwanted amplitude-to-voltage gain is of the order of 5-50 mV, which is 12-35 dB lower than the phase-to-voltage gain of the mixer. In addition, the trick of setting the mixer at a sweet point -- off the quadrature condition -- where the sensitivity to AM nulls, works only with microwave mixers. The HF-VHF mixers have not this sweet point. Moreover, we prove that if the AM noise comes from the oscillator under test, it can not be rejected by correlation. At least not with the schemes currently used. An example shows that at some critical frequencies the unwanted effect of AM noise is of the same order -- if not greater -- than the phase noise. Thus, experimental mistakes are around the corner.

description: L’idea di dar vita a questo volume nasce dallo stimolante confronto sul tema dell’orario di lavoro organizzato dai dottorandi e dai giovani ricercatori dell’Università Sapienza di Roma. Gli scritti riprendono gli interventi dei relatori del webinar “Tempi di lavoro e di riposo: leggi nazionali, norme europee e interventi della Corte di Giustizia”, da cui il titolo del volume, tenutosi il 7 aprile 2021. L’opera sviluppa una riflessione corale sul tema dell’orario di lavoro, con particolare attenzione ai suoi limiti e confini, sempre più labili e incerti. I diversi scritti di cui si compone, nonostante le differenze di approccio e di metodo, rivelano l’esistenza di un fitto dialogo tra gli studiosi. La varietà dei temi affrontati dimostra come la disciplina dell’orario di lavoro rappresenti una sede privilegiata per l’osservazione delle trasformazioni del lavoro e per dare conto delle esigenze di tutela della persona durante i periodi di non lavoro. Attraverso le riflessioni degli autori, si comprende come, ancora oggi, l’orario di lavoro rappresenti una sfida innovativa per gli interpreti, che si interrogano alla ricerca di soluzioni ragionevoli.

description: Various aspects of the statistics of work performed by an external classical force on a quantum mechanical system are elucidated for a driven harmonic oscillator. In this special case two parameters are introduced that are sufficient to completely characterize the force protocol. Explicit results for the characteristic function of work and the respective probability distribution are provided and discussed for three different types of initial states of the oscillator: microcanonical, canonical and coherent states. Depending on the choice of the initial state the probability distributions of the performed work may grossly differ. This result in particular holds also true for identical force protocols. General fluctuation and work theorems holding for microcanonical and canonical initial states are confirmed.

description: Automated monitoring and analysis of passenger movement in safety-critical parts of transport infrastructures represent a relevant visual surveillance task. Recent breakthroughs in visual representation learning and spatial sensing opened up new possibilities for detecting and tracking humans and objects within a 3D spatial context. This paper proposes a flexible analysis scheme and a thorough evaluation of various processing pipelines to detect and track humans on a ground plane, calibrated automatically via stereo depth and pedestrian detection. We consider multiple combinations within a set of RGB- and depth-based detection and tracking modalities. We exploit the modular concepts of Meshroom [2] and demonstrate its use as a generic vision processing pipeline and scalable evaluation framework. Furthermore, we introduce a novel open RGB-D railway platform dataset with annotations to support research activities in automated RGB-D surveillance. We present quantitative results for multiple object detection and tracking for various algorithmic combinations on our dataset. Results indicate that the combined use of depth-based spatial information and learned representations yields substantially enhanced detection and tracking accuracies. As demonstrated, these enhancements are especially pronounced in adverse situations when occlusions and objects not captured by learned representations are present.

Postwar industrial relations and the origins of lean production in Japan (1945-1973)
Creators: name: Price, John
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the evolution of postwar industrial relations in postwar Japan from 1945 to 1973. It analyzes the impact of postwar industrial relations institutions on the origins and development of “lean production” or, as it is otherwise known, the Toyota production system. It uses three case studies, Mitsui Coal’s Miike mine in Kyushu, Suzuki Motors in Hamamatsu, and Moriguchi City Hall as an empirical basis for analysis and constructs a schema of industrial relations institutions that challenges the conventional “three pillars” interpretation (lifetime employment, seniority-based wages, and enterprise unions). From a historical perspective there were three distinct stages in the evolution of industrial relations. The first, from 1945-1947 was a labour-dominated period during which unions began to develop a distinct factory regime in which they were equal partners with management and could veto layoffs. Employers rejected this regime, however, and led an offensive against the independent union movement. This offensive was relatively successful in weakening labour and overturning the new institutions, but it engendered further antagonism. Thus the 1950s were characterized by instability in labour relations and new institutions had to evolve out of the workplace. A stable Fordist regime consolidated in the 1960-1973 period. From a comparative perspective and in the context of the development of lean production, the author stresses four institutions: tacit and limited job tenure; a performance-based wage system controlled by management; unions with an enterprise (i.e. market) orientation; and joint consultation. These institutions gave Japanese industrial relations their distinctiveness and also help to explain why lean production developed in Japan. Under the traditional Fordist model, work was broken down into short, repetitive cycles and organized along an assembly line. Employers exerted control by keeping conceptual activities as their mandate and workers were to simply follow instructions. This study found that work itself did not change substantively under lean production but workers participated more in conceptual activities. One of the key reasons for this was that employers in Japan were able to exercise control not only through the division of labour but through the wage system and enterprise unions as well. These mechanisms put discrete limits on the scope of worker innovations. They also limited the benefits workers could expect from the system. Lean production represented a new stage in production, identified as lean, intensified Fordism.

Ο προσδιορισμός αυτός χωρίζεται σε τρία στάδια. Στο πρώτο στάδιο, τροποποιούμε, ίσως για πρώτη φορά στην βιβλιογραφία, τον ‘κλαδικό’ δείκτη Balassa σε ‘χωρικό’ δείκτη, ώστε αντί να υπολογίζει το συγκριτικό πλεονέκτημα μιας χώρας προς ένα προϊόν, να μετρά το συγκριτικό πλεονέκτημα προς μια άλλη χώρα. Έπειτα επιλέγουμε κάποιες μεταβλητές, οι οποίες καλύπτουν σε σημαντικό βαθμό την θεωρία του διεθνούς εμπορίου και τις κυριότερες παραμέτρους μιας εθνικής οικονομίας. Στην συνέχεια κατασκευάζουμε 4 διαφορετικές οικονομετρικές εξισώσεις για την κάθε χώρα, με εξαρτημένη μεταβλητή το τροποποιημένο Αποκαλυπτόμενο Συγκριτικό Πλεονέκτημα (RCA) και ανεξάρτητες μεταβλητές τις παραπάνω. Σκοπός της εμπειρικής μας ανάλυσης είναι να ερμηνεύσουμε από ποιες παραμέτρους εξαρτάται το «spatial RCA», αλλά και πώς αυτές μεταβλήθηκαν από το 2001 έως το 2013. Μετά την εμπειρική ανάλυση, ακολουθεί μία επισκόπηση του εμπορίου της Ελλάδας, συγκρίνοντας τα έτη 2001 - 2015 και παρουσιάζοντας μία διεισδυτική κλαδική και χωρική ανάλυση, αντλώντας στοιχεία από το Διεθνές Κέντρο Εμπορίου (ITC). Η παρούσα μελέτη έχει αρκετό ενδιαφέρον, λόγω του νέου χωρικού δείκτη RCA καθώς επίσης περιλαμβάνεται σε μία σχετικά περιορισμένη βιβλιογραφία, αυτής της χωρικής διάρθρωσης του εμπορίου.
description: The main purpose of this thesis is to define the spatial structure of the export trade for Greece, Italy, Portugal, and Spain. The definition is separated in 3 stages. Firstly, it is modified, maybe for the first time in bibliography, the ‘commodity’ Balassa Index to ‘spatial’ Balassa Index, in order to measure the comparative advantage of an origin country, not to a sector, but to a destination country. Secondly, it is chosen the independent variables, which explain the biggest part of trade theory, and cover as well, the most important figures of a national economy. Thirdly, it is constructed 4 econometric models for each country, taken as a dependent variable the spatial Revealed Comparative Advantage, and as independent the variables above. In other words, the target of the empirical analysis is to explicate the variables which affect the spatial RCA, and also to notice the changes that happened between 2001 and 2013. After the econometric analysis, it follows a thorough description of Greek trade, by comparing the years of 2001 and 2015 and finally presented a spatial and commodity analysis. The data that are used were drawn by International Trade Center (ITC). In this thesis a lot of attention should be paid to the ‘new’ RCA, because it describes the spatial pattern of trade, which is a quite restricted part in the research of trade analysis.

description: Consider the multiple testing problem of testing null hypotheses $H_1,...,H_s$. A classical approach to dealing with the multiplicity problem is to restrict attention to procedures that control the familywise error rate ($\mathit{FWER}$), the probability of even one false rejection. But if $s$ is large, control of the $\mathit{FWER}$ is so stringent that the ability of a procedure that controls the $\mathit{FWER}$ to detect false null hypotheses is limited. It is therefore desirable to consider other measures of error control. This article considers two generalizations of the $\mathit{FWER}$. The first is the $k-\mathit{FWER}$, in which one is willing to tolerate $k$ or more false rejections for some fixed $k\geq 1$. The second is based on the false discovery proportion ($\mathit{FDP}$), defined to be the number of false rejections divided by the total number of rejections (and defined to be 0 if there are no rejections). Benjamini and Hochberg [J. Roy. Statist. Soc. Ser. B 57 (1995) 289--300] proposed control of the false discovery rate ($\mathit{FDR}$), by which they meant that, for fixed $α$, $E(\mathit{FDP})\leqα$. Here, we consider control of the $\mathit{FDP}$ in the sense that, for fixed $γ$ and $α$, $P\{\mathit{FDP}>γ\}\leq α$. Beginning with any nondecreasing sequence of constants and $p$-values for the individual tests, we derive stepup procedures that control each of these two measures of error control without imposing any assumptions on the dependence structure of the $p$-values. We use our results to point out a few interesting connections with some closely related stepdown procedures. We then compare and contrast two $\mathit{FDP}$-controlling procedures obtained using our results with the stepup procedure for control of the $\mathit{FDR}$ of Benjamini and Yekutieli [Ann. Statist. 29 (2001) 1165--1188].

description: The interplay between the formation of neutron skin and alpha cluster at the dilute surface of neutron-rich nuclei is one of the interesting subjects in the study of neutron-rich nuclei and nuclear clustering. A theoretical model has predicted that the growth of neutron skin will prevent the alpha clustering at the nuclear surface. Quite recently, this theoretical perspective; the suppression of alpha clustering by the neutron-skin formation was first confirmed experimentally in Sn isotopes as the reduction of the (p, p alpha) reaction cross-section. Motivated by the novel discovery, in this work, we have investigated the relationship between the neutron-skin thickness and alpha clustering in C isotopes. Based on the analysis by the antisymmetrized molecular dynamics, we show that the alpha spectroscopic factor at nuclear exterior decreases in neutron-rich C isotopes, and the clustering suppression looks correlated with the growth of the neutron-skin thickness.

description: Σκοπός της παρούσας διπλωματικής εργασίας ήταν η μελέτη της πολιτικής διαχείρισης των στερεών αποβλήτων σε νομοθετικό επίπεδο και του βαθμού επίτευξης των στόχων που τίθενται με αυτή. Αρχικά αναφερθήκαμε στο κοινοτικό δίκαιο, παρουσιάζοντας τα κυριότερα σημεία και τις βασικές αρχές που διέπουν την Οδηγία 2008/98/ΕΚ για τα απόβλητα, ενώ παράλληλα αναφερθήκαμε στο ρόλο που διαδραμάτισε διαχρονικά η νομολογία του Δικαστηρίου της Ευρωπαϊκής Ένωσης (ΔΕΕ) στην ερμηνεία και εφαρμογή της κοινοτικής νομοθεσίας για τη διαχείριση των στερεών αποβλήτων. Στη συνέχεια, αναλύσαμε το σχετικό νομοθετικό πλαίσιο στη χώρα μας, με αναφορά στα βασικά σημεία του Ν. 4042/2012, με τον οποίο εναρμονίστηκε το εθνικό δίκαιο με την ανωτέρω Οδηγία 2008/98/ΕΚ. Ένα άλλο θέμα που θίξαμε ήταν το νέο μοντέλο διαχείρισης αποβλήτων που εισήγαγε το Εθνικό Σχέδιο Διαχείρισης Αποβλήτων, το οποίο εγκρίθηκε με την Πράξη Υ.Σ. 49/15.12.2015, καθώς και οι στόχοι που τίθενται με αυτό. Ακολούθως, ασχοληθήκαμε με τα βασικά ζητήματα αναφορικά με τη διαχείριση των στερεών αποβλήτων που εντοπίζονται στην πρόσφατη νομολογία του Συμβουλίου της Επικρατείας, επιχειρώντας, παράλληλα, μία σύγκριση με τα αντίστοιχα ζητήματα που έχουν απασχολήσει το ΔΕΕ. Επιπλέον, παρουσιάσαμε τις πιο πρόσφατες και πλέον σημαντικές αποφάσεις του ΔΕΕ, με τις οποίες η Ελλάδα έχει καταδικαστεί για παραβάσεις του κοινοτικού δικαίου για τη διαχείριση στερεών αποβλήτων.
description: The aim of the present thesis was the study of waste management policy at the legislative level and the achievement of the objectives set by it. Firstly, we referred to the Community law, presenting the main points and principles underlying Directive 2008/98/EC on waste; also, we discussed the role that over time the jurisprudence of the European Court of Justice (ECJ) played in the interpretation and application of the Community legislation on waste management. Then, we analyzed the legal framework in our country, with reference to the main points of Law 4042/2012, which harmonized the national law with the Directive 2008/98 EC. Another issue that we discussed was the new waste management model introduced by the National Waste Management Plan, which was approved by the Act of Ministerial Council 49 / 12.15.2015, as well as the objectives set by it. Subsequently, we addressed the key issues regarding the management of solid waste identified in the recent jurisprudence of the Council of State, while attempting a comparison with the corresponding issues have occupied the ECJ. Furthermore, we presented the latest and most important decisions of the ECJ, with which Greece is convicted for transgressions of Community law on waste management.

description: Recent works have explored non-perturbative effects due to the existence of (infinitesimal) Gribov copies in Yang-Mills-Chern-Simons theories in three Euclidean dimensions. In particular, the removal of such copies modify the gauge field propagator by a self-consistent dynamically generated mass parameter, the Gribov parameter. Due to the interplay with the topological mass introduced by the Chern-Simons term, the propagator features a non-trivial set of phases with poles of different nature, leading to the possible interpretation of a confinfing to deconfining phase transition. Inhere, we restore the BRST symmetry which is softly broken by the elimination of gauge copies and provide a BRST-invariant discussion of such a transition. In order to make clear all physical statements, we deal with linear covariant gauges which contain a gauge parameter and therefore allow for an explicit check of gauge parameter independence of physical results. We also discuss the generation of condensates due to the infrared relevance of infinitesimal Gribov copies.

description: It was first suggested by Englander et al to model the nonlinear dynamics of DNA relevant to the transcription process in terms of a chain of coupled pendulums. In a related paper [q-bio.BM/0604014] we argued for the advantages of an extension of this approach based on considering a chain of double pendulums with certain characteristics. Here we study a simplified model of this kind, focusing on its general features and nonlinear travelling wave excitations; in particular, we show that some of the degrees of freedom are actually slaved to others, allowing for an effective reduction of the relevant equations.

description: In a recent paper a pair of operators $a$ and $b$ satisfying the equations $a^\dagger a=bb^\dagger+γ\1$ and $aa^\dagger=b^\dagger b+δ\1$, has been considered, and their nature of ladder operators has been deduced and analysed. Here, motivated by the spreading interest in non self-adjoint operators in Quantum Mechanics, we extend this situation to a set of four operators, $c$, $d$, $r$ and $s$, satisfying $ dc=rs+γ\1$ and $cd=sr+δ\1$, and we show that they are also ladder operators. We show their connection with biorthogonal families of vectors and with the so-called $\D$-pseudo bosons. Some examples are discussed.

description: We present analysis of XMM-Newton Optical Monitor observations in the near-ultraviolet of HD 189733, covering twenty primary transits of its hot Jupiter planet. The transit is clearly detected with both the UVW2 and UVM2 filters, and our fits to the data reveal transit depths in agreement with that observed optically. The measured depths correspond to radii of $1.059^{+0.046}_{-0.050}$ and $0.94^{+0.15}_{-0.17}$ times the optically-measured radius (1.187 R$_{\rm J}$ at 4950 Å) in the UVW2 and UVM2 bandpasses, respectively. We also find no statistically significant variation in the transit depth across the 8 year baseline of the observations. We rule out extended broadband absorption towards or beyond the Roche lobe at the wavelengths investigated, although observations with higher spectral resolution are required to determine if absorption out to those distances from the planet is present in individual near-UV lines.
