description: The COVID-19 pandemic has resulted in a radical increase in the use of face masks as a protective measure against the virus all over the world. Facial concealment has been accused of obstructing the production of speech and, therefore, the perception by listeners, making, in this way, the communication more difficult. In this study, we explore the effect of the two main masks used against the spread of the pandemic (the surgical mask and the cloth mask) on the acoustic properties of Greek nasals and voiceless fricatives. We also examine whether there is a difference in the way the two face masks affect the speech production. The sounds are produced by eight speakers of both genders and are examined in three-syllable words in onset and medial position, stressed and unstressed condition and in different vowel environments. The results showed that the facewear had a greater effect on the non-sibilant fricatives and especially their intensity, while the nasals were barely affected. Between the two facemasks, it was proven that the cloth mask affected the production to a greater extent. In addition, besides the sound absorption, the increased vocal effort and the speakers’ behavior towards the face masks played a significant role in the results.
description: Η πανδημία COVID-19 έχει οδηγήσει σε μια ραγδαία αύξηση της χρήσης μάσκας προσώπου ως προστατευτικού μέτρου κατά του ιού σε όλο τον κόσμο. Η απόκρυψη του προσώπου έχει κατηγορηθεί ότι παρεμποδίζει την παραγωγή λόγου και, ως εκ τούτου, την αντίληψη των ακροατών, καθιστώντας, με αυτόν τον τρόπο, την επικοινωνία δυσκολότερη. Σε αυτή τη μελέτη, διερευνούμε την επίδραση των δύο κύριων μασκών που χρησιμοποιούνται κατά της εξάπλωσης της πανδημίας (της χειρουργικής μάσκας και της υφασμάτινης μάσκας) στις ακουστικές ιδιότητες των ρινικών και άηχων εμποδιστικών συμφώνων στα Ελληνικά. Εξετάζουμε επίσης κατά πόσον υπάρχει διαφορά στον τρόπο με τον οποίο οι δύο μάσκες προσώπου επηρεάζουν την παραγωγή λόγου. Οι ήχοι παράγονται από οχτώ ομιλητές και των δύο φύλων και εξετάζονται σε τρισύλλαβες λέξεις σε αρχική και μεσαία θέση, τονισμένη και άτονη και σε διαφορετικά περιβάλλοντα φωνήεντος. Μεταξύ των δύο μασκών προσώπου, αποδείχθηκε ότι η υφασμάτινη μάσκα επηρέασε την παραγωγή λόγου σε μεγαλύτερο βαθμό. Επιπλέον, εκτός από την απορρόφηση του ήχου, η αυξημένη φωνητική προσπάθεια και η συμπεριφορά των ομιλητών προς τις μάσκες προσώπου έπαιξαν σημαντικό ρόλο στα αποτελέσματα.
Universality of affine formulation in General Relativity theory

description: Affine variational principle for General Relativity, proposed in 1978 by one of us (J.K.), is a good remedy for the non-universal properties of the standard, metric formulation, arising when the matter Lagrangian depends upon the metric derivatives. Affine version of the theory cures the standard drawback of the metric version, where the leading (second order) term of the field equations depends upon matter fields and its causal structure violates the light cone structure of the metric. Choosing the affine connection (and not the metric one) as the gravitational configuration, simplifies considerably the canonical structure of the theory and is more suitable for purposes of its quantization along the lines of Ashtekar and Lewandowski (see http://www.arxiv.org/gr-qc/0404018). We show how the affine formulation provides a simple method to handle boundary integrals in general relativity theory.

description: No abstracts are to be cited without prior reference to the author.Many maritime countries in Europe have marine environmental monitoring programmes which include the measurement of chemical contaminants and related biological effects. How best to integrate these two types of monitoring data into meaningful assessments has been the subject of much recent effort by a number of ICES Working and Study Groups including SGIMC and WGBEC. The output from this process has culminated in draft OSPAR guidelines and an ICES CRR in press. The OSPAR guidelines have been adopted (in 2012) on a trial basis for the period of 3 years to establish their practical applicability The work has concentrated on defining a core set of techniques that can be used across maritime areas, defining confounding factors, supporting parameters and standards for measurement. Most importantly the output of the work has defined assessment criteria for biological effect measurements and suggests how these measurements can be used in an integrated manner together with chemical contaminant measurements in biota, sediments and water. The scientific basis for this approach is presented. The approach is also considered to provide a potential tool for EU member states to determine whether Good Environmental Status (GES) for Descriptor 8 is being achieved i.e. concentrations of contaminants are at levels not giving rise to pollution. National and international case studies to demonstrate the approach have been recently trialled and suggest that adoption of the approach adds value to environmental assessments.

description: We study the heat relaxation in current biased metallic films in the regime of strong electron-phonon coupling. A thermal gradient in the direction normal to the film is predicted, with a spatial temperature profile determined by the temperature-dependent heat conduction. In the case of strong phonon scattering the heat conduction occurs predominantly via the electronic system and the profile is parabolic. This regime leads to the linear dependence of the noise temperature as a function of voltage bias, in spite of the fact that all the dimensions of the film are large compared to the electron-phonon relaxation length. This is in stark contrast to the conventional scenario of relaxation limited by the electron-phonon scattering rate. A preliminary experimental study of a 200 nm thick NbN film indicates the relevance of our model for materials used in superconducting nanowire single-photon detectors.

description: The subject of this dissertation thesis is the study of consent systems regarding organ procurement in the field of transplantation. In the context of this thesis, there is initially an introduction to the concept of transplantation and a brief review of the legislation that has been enacted in Greek legal order. Also, we presented a comparative overview of the consent systems prevailing in other countries. We examined the issue of informing patients, in this case the donor and the recipient, and more specifically the content of the information and the time at which it should be carried out. Another issue we mentioned is the end of human life and brain death. Furthermore, we covered in detail the issue of consent from a living, cadaveric and finally a minor donor, presented the prevailing consent systems and made a brief comparison of the two most recent transplantation laws in force in our country, Law No. 2737/1999 and Law No. 3984/2011. Finally, we raised some concerns regarding the various proposed consent systems, made a brief comparison between the declared and presumed consent system, made some ethical considerations and drew some useful conclusions.

description: In this work we develop the maximum likelihood detection (MLD) algorithm for noncoherent amplitude shift keying (NCASK) systems in additive white Gaussian noise (AWGN) channels. The developed algorithm was used to investigate the performance of the NCASK system with convolutional coding and soft-decision Viterbi decoding. Tight and simple upper bounds have been derived to describe the system performance; simulation results have shown that the derived upper bounds are within 0.1 dB of the simulated points.

Search for Colour Reconnection Effects in e+e- -> W+W- -> hadrons through Particle-Flow Studies at LEP

Year: 2003
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search for colour reconnection effects in hadronic decays of W pairs is performed with the L3 detector at centre-of-mass energies between 189 and 209 GeV. The analysis is based on the study of the particle flow between jets associated to the same W boson and between two different W bosons in qqqq events. The ratio of particle yields in the different interjet regions is found to be sensitive to colour reconnection effects implemented in some hadronisation models. The data are compared to different models with and without such effects. An extreme scenario of colour reconnection is ruled out.

description: Magnetic nanoparticles were integrated with graphene oxide sheets modified by metformin to introduce polyamine functionality in structure. Modified magnetic graphene oxide by metformin (MMGO) adsorption ability was studied for removal of methyl violet (MV) and acid red 88 (AR88) at different pH, initial concentration, and contact time. The successful preparation of magnetic nanoparticles supported with modified graphene oxide sheets is evident from FTIR spectra, TGA, zeta-potential and magnetic measurements. Morphology and chemical structure of the preparedMMGO nanocompositewas studied by TEM, SEM, XPS and EDS analyses. Surface area measurement of the MMGO composite revealed high BET surface area of 226 m2 g−1. Equilibrium isotherms were employed to evaluate the experimental data and calculate the isotherms' parameters. Results showed that adsorption process is based on Langmuir isotherm (R2 N 0.99) and adsorption capacity of fabricated nano-composite was found to be 243 mg g−1 for MV and 303 mg g−1 for AR88. Kinetical results were based on pseudo-second order (R2 N 0.99) and physisorption was main process in the rate-controlling step.

description: No abstracts are to be cited without prior reference to the author.Criteria and indicators related to the assessment of benthic habitats are included in descriptor 1, 4 and 6 of the Marine Strategy Framework Directive (MSFD). Therefore, an appropriate, integrative assessment procedure for this habitat type shall contribute to an integrated assessment of the marine status. An assessment procedure for determining the good environmental status (GES) of benthic habitats requires the attention of the following topics: (1) the selection and integration of complementary indicator tools to assess the structure and function of the benthic ecosystem (indicator approach), (2) a habitat assignation of the area (habitat approach), (3) reference or target conditions for the different benthic parameters (reference approach) (Figure 1).
The Lifetime Asymmetry of Polarized Muons in Flight

description: Based on the parity violation in Standard Model, we study the dependence of the lifetime on the polarization of an initial-state fermion in weak interactions. The fermion lifetime was usually calculated in terms of spin states. However, after comparing spin states with helicity states and chirality states, it is pointed out that a spin state is helicity degenerate, and the spin state and the helicity state are entirely different. Using helicity states, we calculate the lifetime of polarized muons. The result shows that the lifetime of right-handed polarized muons is always greater than that of left-handed polarized muons with the same speed in flight.

description: This article is an account of the NABUCO project achieved during the summer camp CEMRACS 2019 devoted to geophysical fluids and gravity flows. The goal is to construct finite difference approximations of the transport equation with nonzero incoming boundary data that achieve the best possible convergence rate in the maximum norm. We construct, implement and analyze the so-called inverse Lax-Wendroff procedure at the incoming boundary. Optimal convergence rates are obtained by combining sharp stability estimates for extrapolation boundary conditions with numerical boundary layer expansions. We illustrate the results with the Lax-Wendroff and O3 schemes.

description: Diava, the UNESCO-protected practise of livestock herding for hundreds of kilometres between summer and winter, is a centuries old Greek, pastoral tradition that is kept alive despite the emergence of new technologies. Throughout time and space, pastoral migration has been at the core of the cultural and social composition of the mountainous farming communities of the Balkans, contributing to shaping and developing the landscape of the areas they took place from the emergence of the Greek state onwards. This thesis explores the ‘making of’ the author’s ambitious photojournastic project on the practice of Diava in Northern Greece, published in Deutsche Welle in March 2021. After a concise literature review and background information in the introductory chapter, Chapter 1 explores the relationship between the media and their impact on the environment with a special focus on the coverage of environmental news and the emergence of environmental storytelling on multimedia platforms. Chapter 2 offers a brief introduction to various ethnographic tools employed by journalists such as field observation, ethnographic interviews and indigenous knowledge. Last but not least, Chapter 3 describes the methodology utilised for the completion of the project, which received the first prize in the Athens Photo World Award 2021.

description: No abstracts are to be cited without prior reference to the author.Descriptor 8 of the Marine Strategy Framework Directive (MSFD) requires that “Concentrations of contaminants are at levels not giving rise to pollution effects” in order for Good Environmental Status (GES) to be achieved. Prior to publication of the MSFD, OSPAR/ICES Working and Study Groups identified a coherent set of biological effects measurements spanning various trophic levels and levels of biological organisation, and developed a scheme to produce a holistic assessment of environmental status with respect to contaminants through integration of the biological effects measurements with chemical concentration data. To trial the integrated approach, we established a demonstration programme that included the determination of biological effects responses in mussels and flounder in addition to existing monitoring for the OSPAR CEMP that included chemical analyses of biota and sediment, and biological effects responses such as imposex in dogwhelks and EROD activity in flatfish. We demonstrated the utility of the OSPAR/ICES scheme by conducting an integrated assessment of the Forth estuary and the Firth of Forth, including measurements in dogwhelks, mussels, fish, water (passive sampling), and sediment. Contaminant concentrations and effects showed an inshore-offshore gradient within the Forth sea area and whilst most were below levels of concern, there were individual cases that exceeded the environmental assessment criteria. An assessment of these data is presented which integrates across determinants, matrices and sites which provides information about the status of the area using indicators that may be used for Descriptor 8.

description: Measuring high energy cosmic ray electrons/positrons (CRE) provides important means for the dark matter (DM) indirect detection and for probing the nearby galactic sources. In this work, we perform a systematic analysis of the flavor structure of DM annihilations into charged leptons based on the cosmic ray CRE spectra measured by DAMPE, Fermi-LAT, AMS-02, and CALET experiments. We study the annihilations of possible TeV scale DM particles in a nearby subhalo, which is proposed to explain the possible peak-like structure of the DAMPE CRE data. We pay special attention to the possible non-resonant excess (besides the possible peak-like structure) and demonstrate that such non-resonant excess can mainly arise from the decay of muons produced by the DM annihilations in the subhalo. With these we study the flavor composition of the lepton final states from DM annihilations $χχ\to e^+e^-, μ^+μ^-, τ^+τ^-$ by fitting the CRE data. We demonstrate that decays of the final states $μ^+ μ^-$ and $τ^+ τ^-$ can provide the non-resonant excess, while the peak excess arises from the $e^+ e^-$ final state. We further analyze the constraints on the lepton flavor composition using the Fermi-LAT $γ$-ray measurements. We find that the flavor composition is consistent with the Fermi-LAT data at relatively low Galactic latitudes, while the fraction of the final state $τ^\pm$ is severely bounded.

description: Continuous Nb wires, 7-15 nm in diameter, have been fabricated by sputter-coating single fluorinated carbon nanotubes. Transmission electron microscopy revealed that the wires are polycrystalline, having grain sizes of about 5 nm. The critical current of wires thicker than ~12 nm is very high (10^7 A/cm^2) and comparable to the expected depairing current. The resistance versus temperature curves measured down to 0.3 K are well described by the Langer-Ambegaokar-McCumber-Halperin (LAMH) theory of thermally activated phase slips. Quantum phase slips are suppressed.

description: A group of noroxymorphone derivatives were subjected to Gewald reaction conditions to prepare their respective aminothieno products. In refluxing piperidine/ethanol, 1a–g reacted with elemental sulfur and malononitrile to produce 2a–g in high yields. Reactions took place in one pot and completed within 4–7 h and products precipitated spontaneously in the reaction mixtures.

description: No abstracts are to be cited without prior reference to the author.Fishing can change the structure of marine food webs, impairing ecosystem functioning, with the removal of high trophic level target species changing fish abundance and composition at lower trophic levels (Pauly et al., 1998). The Marine Strategy Framework Directive (MSFD) requires indicators of “Abundance trends of functionally important selected groups/species” to identify Good Environmental Status, with the large fish indicator (LFI) subsequently developed to measure the proportion by weight of fish above a specified length threshold (Greenstreet et al., 2011; Shephard et al., 2011). However, this indicator measures changes in the size composition of fish communities, and not changes in the proportion of top predators. While changes in trophic composition are indicated by changes in size composition, as body size is generally related to trophic position in marine food webs, this may not always be the case. For example, in the North Sea, a decline in the size composition of fish communities did not coincide with a decline in the trophic composition; large bodied high trophic level predators were replaced by smaller bodied predators feeding at the same trophic level (Jennings et al., 2002). Hence, ecological indicators under the MSFD need to be developed which consider all components of the fish community, and not simply those occupying higher trophic levels.

description: It is argued that, using the black hole area entropy law together with the Boltzmann-Gibbs statistical mechanics and the quasinormal modes of the black holes, it is possible to determine univocally the lowest possible value for the spin $j$ in the context of the Loop Quantum Gravity theory which is $j_{min}=1$. Consequently, the value of Immirzi parameter is given by $γ= \ln 3/(2π\sqrt{2})$. In this paper, we have shown that if we use Tsallis microcanonical entropy rather than Boltzmann-Gibbs framework then the minimum value of the label $j$ depends on the nonextensive $q$-parameter and may have values other than $j_{min}=1$.

description: Η σωστή διαχείριση των αποθεμάτων αποτελεί ένα πολύ σημαντικό μέρος της ορθής διαχείρισης σε έναν οργανισμό. Ιδιαίτερα στην περίπτωση του ιδιωτικού φαρμακείου και δη στην περίπτωση των φαρμάκων η διαχείριση αυτή αποκτά ένα επιπλέον νόημα καθώς αφορά ένα ιδιαίτερο προϊόν που αποτελεί κοινωνικό αγαθό το οποίο οφείλει να βρίσκεται διαθέσιμο σε πρώτη ζήτηση. Η πολυπλοκότητα και η μεταβλητότητα που παρατηρείται συχνά στις εφοδιαστικές αλυσίδες πρέπει συνεπώς να αντισταθμιστεί από μία διαχείριση η οποία θα σκοπεί αφενός στη διαφύλαξη της δημόσιας υγείας, αφετέρου στους εταιρικούς στόχους που το φαρμακείο έχει ως επιχείρηση. Η παρούσα εργασία έχει πολλαπλούς στόχους. Αρχικά παρουσιάζει συνοπτικά την αναγκαιότητα που αποτελεί η σωστή διαχείριση των αποθεμάτων για έναν οργανισμό. Ακολούθως επιχειρεί να παρουσιάσει τις ιδιαιτερότητες που υπάρχουν εγγενώς στην εφοδιαστική αλυσίδα του φαρμάκου, προσπαθώντας ταυτόχρονα να παρουσιάσει συνοπτικά το πρόβλημα της διαχείρισης των αποθεμάτων όπως αυτό διαμορφώνεται με βάση τα δεδομένα του ελληνικού ιδιωτικού φαρμακείου. Στη συνέχεια παρουσιάζονται ντετερμινιστικά και στοχαστικά μοντέλα για τη διαχείριση των αποθεμάτων μαζί με τη μαθηματική τους ανασκόπηση. Τέλος αφού παρουσιαστούν τρόποι αξιολόγησης τόσο της ορθότητας στη διαχείριση όσο και της επάρκειας/ποιότητας/ικανοποίησης από τους προμηθευτές γίνονται προτάσεις για μελλοντική έρευνα
description: Effective inventory management is a very important part of effective management in an organization. Especially in the case of the private pharmacy and even more so in the case of medicines, the latter acquires an additional meaning as it concerns a special case of consumer product, a public good, which must be available in first demand. The complexity and variability that is often inherent in supply chains must therefore be offset by an active management that aims to preserve public health but also adhere to the corporate objectives of the pharmacy as a company. The present work has multiple objectives. Firstly, it summarizes the need for proper inventory management for an organization in general. Continuing it tries to present the peculiarities that inherently exist in the supply chain of medicines, while trying to summarize the problem of inventory management as it is formed based on the environment of the Greek private pharmacy. Following, are presented deterministic and stochastic models for inventory management, with a summarizing mathematical approach. Finally, after presenting ways of evaluating both the effectiveness in the management as well as the adequacy/quality of and satisfaction from the suppliers, suggestions are made for future research

description: We propose a family of very efficient hierarchical indexing schemes for ungapped, score matrix-based similarity search in large datasets of short (4-12 amino acid) protein fragments. This type of similarity search has importance in both providing a building block to more complex algorithms and for possible use in direct biological investigations where datasets are of the order of 60 million objects. Our scheme is based on the internal geometry of the amino acid alphabet and performs exceptionally well, for example outputting 100 nearest neighbours to any possible fragment of length 10 after scanning on average less than one per cent of the entire dataset.

The influence of baryons on the chiral phase transition in QCD

description: A qualitative analysis of the chiral phase transition in QCD with two massless quarks and non--zero baryon density is performed. It is assumed that at zero baryonic density, $ρ=0$, the temperature phase transition is of the second order. Due to a specific power dependence of baryon masses on the chiral condensate the phase transition becomes of the first order at the temperature $T=T_{\mathrm{ph}}(ρ)$ for $ρ>0$. At temperatures $T_{\mathrm{cont}}(ρ) > T > T_{\mathrm{ph}}(ρ)$ there is a mixed phase consisting of the quark phase (stable) and the hadron phase (unstable). At the temperature $T = T_{\mathrm{cont}}(ρ)$ the system experiences a continuous transition to the pure chirally symmetric phase.

description: The Fast Folding Algorithm (FFA) is a phase-coherent search technique for periodic signals. It has rarely been used in radio pulsar searches, having been historically supplanted by the less computationally expensive Fast Fourier Transform (FFT) with incoherent harmonic summing (IHS). Here we derive from first principles that an FFA search closely approaches the theoretical optimum sensitivity to all periodic signals; it is analytically shown to be significantly more sensitive than the standard FFT+IHS method, regardless of pulse period and duty cycle. A portion of the pulsar phase space has thus been systematically under-explored for decades; pulsar surveys aiming to fully sample the pulsar population should include an FFA search as part of their data analysis. We have developed an FFA software package, riptide, fast enough to process radio observations on a large scale; riptide has already discovered sources undetectable using existing FFT+IHS implementations. Our sensitivity comparison between search techniques also shows that a more realistic radiometer equation is needed, which includes an additional term: the search efficiency. We derive the theoretical efficiencies of both the FFA and the FFT+IHS methods and discuss how excluding this term has consequences for pulsar population synthesis studies.

description: We study the thermodynamics of the delta-chain with competing ferro- and antiferromagnetic interactions in an external magnetic field which generalizes the field-free case studied previously. This model plays an important role for the recently synthesized compound Fe$_{10}$Gd$_{10}$ which is nearly quantum critical. The classical version of the model is solved exactly and explicit analytical results for the low-temperature thermodynamics are obtained. The spin-$s$ quantum model is studied using exact diagonalization and finite-temperature Lanzos techniques. Particular attention is focused on the magnetization and the susceptibility. The magnetization of the classical model in the ferromagnetic part of the phase diagram defines the universal scaling function which is valid for the quantum model. The dependence of the susceptibility on the spin quantum number $s$ at the critical point between the ferro- and ferrimagnetic phases is studied and the relation to Fe$_{10}$Gd$_{10}$ is discussed.

description: We extend a recently introduced mapping model, which explains the bunching phenomenon in an ion beam resonator for two ions [Geyer, Tannor, J. Phys. B 37 (2004) 73], to describe the dynamics of the whole ion bunch. We calculate the time delay of the ions from a model of the bunch geometry and find that the bunch takes on a spherical form at the turning points in the electrostatic mirrors. From this condition we derive how the observed bunch length depends on the experimental parameters. We give an interpretation of the criteria for the existence of the bunch, which were derived from the experimental observations by Pedersen et al [Pedersen etal, Phys. Rev. A 65 042704].

description: We explicitly calculate Janossy densities for a special class of finite determinantal point processes with several types of particles introduced by Prähofer and Spohn and, in the full generality, by Johansson in connection with the analysis of polynuclear growth models. The results of our paper generalize the theorem we proved earlier with Borodin about the Janossy densities in biorthogonal ensembles. In particular, our results can be applied to coupled random matrices.
