description: Interactions that animals experience can have a significant influence on their health and welfare. These interactions can occur between animals themselves, but also between animals and keepers, and animals and the public. Human and non-human animals come into contact with each other in a variety of settings, and wherever there is contact there is the opportunity for interaction to take place. Interaction with companion animals are well known, but human–animal interaction (HAR) (Hosey, 2008) also occurs in the context of farms (Hemsworth and Gonyou, 1997; Hemsworth, 2003), laboratories (Chang and Hart, 2002), zoos (Kreger and Mench, 1995) and even the wild (e.g. Cassini, 2001). This project proposes a permanent monitoring scheme to record animal-human interactions and animal-animal interactions in zoos. This will be accompanied by a survey of animal personality for welfare, husbandry, breeding programs and reintroduction purposes. The pilot project is currently based on direct monitoring of animal behaviour, use of time lapse cameras and animal personality questionnaires completed by experienced keepers. The goal of this project is to create a network between zoos to explore the aforementioned interactions to produce husbandry protocols and explore personality and behavioural traits in multiple species. We present provisional data regarding polar bear (Fasano Zoosafari, Italy), Sumatran tigers, Amur tigers and Asiatic lion (ZSL London and Whipsnade zoo) interactions with humans and conspecifics. This data is collected across a broad range of environmental conditions and outlines the monitoring protocols developed to collect this data.
 The first year data show the great adaptability of these species to ex situ environments, low or absent negative impact of visitors’ presence and the relevance of individual personality in these interactions.

description: Aims: This paper commences a series devoted to the study of the stellar content of early-type galaxies. The goal of the series is to set constraints on the evolutionary status of these objects. Methods: In this paper we describe the details of the galaxy sample, the observations, and the data reduction. Line-strength indices and velocity dispersions sigma are measured in 98 early-type galaxies drawn from different environments, and the relation of the indices with the velocity dispersion analysed in detail. Results: The present sample indicates that some of the index-sigma relations depend on galaxy environment. In particular, the slope of the relation between Balmer lines and sigma is steeper for galaxies in the Virgo cluster, small groups, and in the field than for galaxies in the Coma cluster. In several indices there is also a significant offset in the zero point between the relations defined by the different subsamples. The slopes of the index-sigma relation for the Virgo and low-density environment galaxies are explained by a variation of both age and metallicity with velocity dispersion, as previously noted in other studies. For the galaxies in the Coma cluster, however, the relation of the indices with sigma only requires a variation of the abundance along the sigma sequence. In agreement with other studies we find that the models that better reproduce the slopes are those in which the alpha elements vary more than the Fe-peak elements along the sigma sequence, while, at a given sigma, older galaxies show an higher alpha/Fe ratio. Conclusions: The results can be explained assuming that galaxies in the Coma cluster have experienced a truncated star formation and chemical enrichment history compared to a more continuous time-extended history for their counterparts in lower density environments.

Wavepacket dynamics of the nonlinear Harper model

description: The destruction of anomalous diffusion of the Harper model at criticality, due to weak nonlinearity $χ$, is analyzed. It is shown that the second moment grows subdiffusively as $ \sim t^α$ up to time $t^*\sim χ^γ$. The exponents $α$ and $γ$ reflect the multifractal properties of the spectra and the eigenfunctions of the linear model. For $t>t^*$, the anomalous diffusion law is recovered, although the evolving profile has a different shape than in the linear case. These results are applicable in wave propagation through nonlinear waveguide arrays and transport of Bose-Einstein condensates in optical lattices.

Various results about these subalgebras are proven by presenting them in the notation of the St Petersburg school. These results are then used to demonstrate the integrability, and find the symmetries, of two types of physical system: twisted Gaudin magnets, and Calogero-type models of particles on several half-lines meeting at a point.

description: We study the gluonic phase in a two-flavor color superconductor as a function of the ratio of the gap over the chemical potential mismatch,$Δ/δμ$. We find that the gluonic phase resolves the chromomagnetic instability encountered in a two-flavor color superconductor for $Δ/δμ< \sqrt{2}$. We also calculate approximately the free energies of the gluonic phase and the single plane-wave LOFF phase and show that the former is favored over the latter for a wide range of coupling strengths.

description: The purpose of this thesis is to implement a complete UTBB FD-SOI MOSFET process flow in a commercially available 2D TCAD-environment and estimate the trans-capacitances after an AC-analysis simulation. TCAD simulation tools were used for the definition of the theoretical structure and the comparison between the extracted and the realistic experimental data in order to achieve the best possible convergence. After the verification of the simulated and experimental Id-Vg characteristics, figure of merits are presented for various channel lengths and back-gate bias conditions. Specifically, parameters such as transconductance (gm), subthreshold-slope (SS) and Ion/Ioff ratio are discussed, along with their variations estimated for different bias conditions. Moreover, variations of the cut-off frequency, delay time and capacitances are also presented for estimating the perspectives of the devices for analog and RF applications.

description: We report the spectroscopic detection of mid-infrared emission from the transiting exoplanet HD 209458b. Using archive data taken with the Spitzer/IRS instrument, we have determined the spectrum of HD 209458b between 7.46 and 15.25 microns. We have used two independent methods to determine the planet spectrum, one differential in wavelength and one absolute, and find the results are in good agreement. Over much of this spectral range, the planet spectrum is consistent with featureless thermal emission. Between 7.5 and 8.5 microns, we find evidence for an unidentified spectral feature. If this spectral modulation is due to absorption, it implies that the dayside vertical temperature profile of the planetary atmosphere is not entirely isothermal. Using the IRS data, we have determined the broad-band eclipse depth to be 0.00315 +/- 0.000315, implying significant redistribution of heat from the dayside to the nightside. This work required development of improved methods for Spitzer/IRS data calibration that increase the achievable absolute calibration precision and dynamic range for observations of bright point sources.

description: We calculate the 1-loop effect in super-Yang-Mills which preserves 1/4-supersymmetries and is holographically dual to the null-like cosmology with a big-bang singularity. Though the bosonic and fermionic spectra do not agree precisely, we do obtain vanishing 1-loop vacuum energy for generic warped plane-wave type backgrounds with a big-bang singularity. Moreover, we find that the cosmological "constant" contributed either by bosons or fermions is time-dependent. The issues about the particle production of some background and about the UV structure are also commented. We argue that the effective higher derivative interactions are suppressed as long as the Fourier transform of the time-dependent coupling is UV-finite. Our result holds for scalar configurations that are BPS but with arbitrary time-dependence. This suggests the existence of non-renormalization theorem for such a new class of time-dependent theories. Altogether, it implies that such a super-Yang-Mills is scale-invariant, and that its dual bulk quantum gravity might behave regularly near the big bang.

description: In this paper we continue the program pioneered by D'Hoker and Phong, and recently advanced by Cacciatori, Dalla Piazza, and van Geemen, of finding the chiral superstring measure by constructing modular forms satisfying certain factorization constraints. We give new expressions for their proposed ansätze in genera 2 and 3, respectively, which admit a straightforward generalization. We then propose an ansatz in genus 4 and verify that it satisfies the factorization constraints and gives a vanishing cosmological constant. We further conjecture a possible formula for the superstring amplitudes in any genus, subject to the condition that certain modular forms admit holomorphic roots.

Η μέθοδος του ψεκασμού η οποία χρησιμοποιήθηκε είναι πολύ χαμηλού κόστους, μεγάλης ευκολίας στην εφαρμογή της και ανεξάρτητη του υποστρώματος, έτσι μπορεί να εφαρμοστεί σε μεγάλη κλίμακα για την προστασία μνημείων πολιτισμού. Διεξήχθησαν πειράματα μέτρησης της γωνίας επαφής και στροφής του νερού όταν αυτό εναποτίθεται στην επιφάνεια του προστατευτικού υμενίου, έγιναν χρωματομετρικές μετρήσεις για να διαπιστωθεί εάν το υμένιο αλλάζει το χρώμα του υποστρώματος, κάτι που δεν συμβαίνει. Επίσης, έγινε peeling test για να διαπιστωθεί η μηχανική αντοχή του υμενίου. Οι πειραματικές μετρήσεις έδειξαν ότι λόγω του σχηματισμού τραχύτητας στη μίκρο- και νάνο-κλίμακα, με το υμένιο αυτό τα υποστρώματα απέκτησαν υδρόφοβο χαρακτήρα, ορισμένες φορές μάλιστα πλησιάζοντας την υπερυδροφοβικότητα. Επιπλέον, έγινε μια θεωρητική προσέγγιση της πιθανής σχέσης της γωνίας στροφής με τη δύναμη προσκόλλησης της σταγόνας στην επιφάνεια και της υδατοαπωθητικότητας, καθώς παρατηρήθηκε ότι επιφάνειες με μεγάλες γωνίες επαφής (>140ο) δεν εμφάνιζαν, αντίστοιχα, μικρή γωνία στροφής.
description: The subject of this diploma thesis was the preparation of hydrophobic thin films on marble’s surface, in order to protect it from rain droplets and air pollutants, in general. These films were created by a spraying process, which is cheap, easy to handle and independent of the substrate used. The above reasons make this method easy to use in large-scale applications for the protection of the heritage monuments. We performed several experiments for the measurement of water’s contact angle on the thin film’s surface, after it was deposited on the substrate. Colorimetric measurements demonstrated that the substrate’s color does not change after the thin film is deposited. We also performed peeling tests, which resulted in very good values for the mechanical stability of the thin film. The morphology of the films was examined using scanning electron microscopy (SEM). The experimental measurements have shown that due to the formation of double-scale roughness (micro- and nano-) all substrates became hydrophobic, sometimes reaching superhydrophobicity. Furthermore, a theoretical study for the correlation between the tilt angle and the adhesion force was performed, since surfaces with high water contact angle (140o) did not have a low tilt angle.

description: This paper presents a new kinematic model based on the Darboux frame for motion control and planning. In this work, we show that an underactuated model of a spin-rolling sphere on a plane with five states and three inputs can be transformed into a fully-actuated one by a given Darboux frame transformation. This nonlinear state transformation establishes a geometric model that is different from conventional state-space ones. First, a kinematic model of the Darboux frame at the contact point of the rolling sphere is established. Next, we propose a virtual surface that is trapped between the sphere and the contact plane. This virtual surface is used for generating arc-length-based inputs for controlling the contact trajectories on the sphere and the plane. Finally, we discuss the controllability of this new model. In the future, we will design a geometric path planning method for the proposed kinematic model.

Long-Term Profile Variability of Double Peaked Emission Lines in Active Galactic Nuclei

description: We present up to two decades of spectroscopic monitoring of the double-peaked broad Halpha emission lines of seven broad-line radio galaxies. These extremely broad, double-peaked lines are successfully modeled by emission from gas in the outer accretion disk, and their profiles vary on timescales of months to years. This variability is a valuable probe for understanding the structure and dynamics of the accretion disk. We characterize the long-term broad-line profile variability in detail, and compare the evolution of the line profiles with predictions from a few simple physical models for dynamical processes in the accretion disk. We find no evidence for persistent, periodic variability that would be indicative of a precessing elliptical disk, or a circular disk with a long-lived, single-armed spiral or warp. We do find transient, periodic variability on the orbital timescale, possibly resulting from shocks induced by tidal perturbations, and variability in the wings of the profile which suggests changes in the emissivity of the inner accretion flow. Dramatic but localized profile changes are observed during flares and high-states of broad-line flux. In 3C 332, these changes can be explained by a slow, smooth, secular change in disk illumination. In Arp 102B and 3C 390.3, however, a simple disk model cannot explain the asymmetric profile changes, suggesting a need for more sophisticated models. We also observe sharp, transient features that appear in the blue peak of the objects, which require a well-organized velocity field.

description: We investigate a species selective cooling process of a trapped $\mathrm{SU}(N)$ Fermi gas using entropy redistribution during adiabatic loading of an optical lattice. Using high-temperature expansion of the Hubbard model, we show that when a subset $N_A < N$ of the single-atom levels experiences a stronger trapping potential in a certain region of space, the dimple, it leads to improvement in cooling as compared to a $\mathrm{SU}(N_A)$ Fermi gas only. We show that optimal performance is achieved when all atomic levels experience the same potential outside the dimple and we quantify the cooling for various $N_A$ by evaluating the dependence of the final entropy densities and temperatures as functions of the initial entropy. Furthermore, considering ${}^{87}{\rm Sr}$ and ${}^{173}{\rm Yb}$ for specificity, we provide a quantitative discussion of how the state selective trapping can be achieved with readily available experimental techniques.

description: The subject of this paper is the consecutive procedure of discretization and quantization of two similar classical integrable systems in three-dimensional space-time: the standard three-wave equations and less known modified three-wave equations. The quantized systems in discrete space-time may be understood as the regularized integrable quantum field theories. Integrability of the theories, and in particular the quantum tetrahedron equations for vertex operators, follow from the quantum auxiliary linear problems. Principal object of the lattice field theories is the Heisenberg discrete time evolution operator constructed with the help of vertex operators.

description: In this talk we consider the problem of a scalar field, non-minimally coupled to gravity, in the presence of a Brane. A number of exact solutions, for a wide range of values of the coupling parameter, are presented. The behavior and general features of these solutions are discussed. We derive solutions for the scalar field compatible with the Randall-Sundrum metric and also geometries which can accomodate a folded kink-like scalar. Analytic and numerical results are provided for the case of a Brane or for smooth geometries, where the scalar field acts as a thick Brane. We also discuss briefly the graviton localization in our setup and demonstrate the characteristic volcano-like localizing potential for gravitons.

description: Recent works have presented promising results from the application of machine learning (ML) to the modeling of flow rates in oil and gas wells. Encouraging results and advantageous properties of ML models, such as computationally cheap evaluation and ease of calibration to new data, have sparked optimism for the development of data-driven virtual flow meters (VFMs). Data-driven VFMs are developed in the small data regime, where it is important to question the uncertainty and robustness of models. The modeling of uncertainty may help to build trust in models, which is a prerequisite for industrial applications. The contribution of this paper is the introduction of a probabilistic VFM based on Bayesian neural networks. Uncertainty in the model and measurements is described, and the paper shows how to perform approximate Bayesian inference using variational inference. The method is studied by modeling on a large and heterogeneous dataset, consisting of 60 wells across five different oil and gas assets. The predictive performance is analyzed on historical and future test data, where an average error of 4-6% and 8-13% is achieved for the 50% best performing models, respectively. Variational inference appears to provide more robust predictions than the reference approach on future data. Prediction performance and uncertainty calibration is explored in detail and discussed in light of four data challenges. The findings motivate the development of alternative strategies to improve the robustness of data-driven VFMs.

description: The Schrodinger equation is solved for many free particles and their quantum entanglement is studied via correlation analysis. Converting the Schrodinger equation in the Madelung hydrodynamic-like form, the quantum mechanics is extended to open quantum systems by adding Ohmic friction forces. The dissipative evolution confirms the correlation decay over time, but a new integral of motion is discovered, being appropriate for storing everlasting quantum information.

description: Η παρούσα εργασία αποτελεί σχολιασμένη μετάφραση από τα γαλλικά στα ελληνικά του άρθρου με τίτλο L'évolution du réalisme au cinéma IV: Les tendances réalistes du cinéma d'aujourd'hui (1940-1960). Το συγκεκριμένο άρθρο αναλύει την εξέλιξη του κινήματος του ρεαλισμού στον κινηματογράφο και των τάσεων που αποτυπώθηκαν στο φιλμ μέσα από το βλέμμα και τον φακό ορισμένων εκ των σπουδαιότερων σκηνοθετών του 20ου αιώνα. Το άρθρο παρακολουθεί τις τεχνολογικές καινοτομίες και την μετατόπιση του ενδιαφέροντος του σύγχρονου δημιουργού / σκηνοθέτη, αλλά και θεατή, από τις ταινίες μυθοπλασίας στις ταινίες που έχουν ως επίκεντρο τον ανθρώπινο πόνο και τα προβλήματα της καθημερινότητας και περαιτέρω καταγράφουν τον απόηχο του πολέμου, ιδωμένο μέσα από τα μάτια των απλών, λαϊκών ανθρώπων. Πρόκειται για ένα θεωρητικό κείμενο που εμπίπτει στο πεδίο της μετάφρασης των ανθρωπιστικών επιστημών και των τεχνών. Ως εκ τούτου, περιλαμβάνει ειδική ορολογία και απαιτεί γνώση του πεδίου (θεωρία του κινηματογράφου). Στην εργασία αιτιολογείται η επιλογή του κειμένου, παρατίθεται στοιχισμένο το πρωτότυπο με το μεταφρασμένο κείμενο, το γλωσσάριο, ενώ τέλος παρουσιάζονται και σχολιάζονται οι ιδιαίτερες δυσκολίες που εντοπίστηκαν κατά τη μετάφρασή του.
description: The present paper is an annotated translation from French to Greek of the article entitled: “L'évolution du réalisme au cinema IV: Les tendances réalistes du cinéma d'aujourd'hui (1940-1960)”. The above-mentioned article analyses the evolution of the movement of realism in cinema and the outlined trends that were depicted on film, through the eyes and the lens of some of the greatest film directors of the 20th century. The article follows the technological innovations as well as the displacement of the contemporary artists’ and viewer’s interest from fiction films to films that focus on human pain and everyday life problems and further depict the aftermath of war as seen through common people’s eyes. It is a theoretical text which falls within the field of humanities and the arts. Therefore, the text is replete with specialised terminology, related to the theory of cinema and requires a degree of knowledge of the respective field. In the present paper, the following are presented: the reasons justifying the choice of the article, the original text aligned to its Greek translation, the glossary of terms found within the text, as well as the particular difficulties encountered during the translation process.

description: Using confocal Raman and fluorescence spectroscopic imaging in 3-dimensions, we show direct evidence for Nd3+-Nd3+ interactions across grain boundaries (GBs) in Nd3+:YAG laser ceramics. It is clearly shown that Nd3+ segregation takes place at GBs leading to self-fluorescence quenching which affects a volume fraction as high as 20%. In addition, we show a clear trend of increasing spatial inhomogeneities in Nd3+ concentration when the doping levels exceeds 3 at%, which is not detected by standard spectrometry techniques. These results could point the way to further improvements in what is already an impressive class of ceramic laser materials.

description: For decades, AE Aquarii (AE Aqr) has been the only cataclysmic variable star known to contain a magnetic propeller: a persistent outflow whose expulsion from the binary is powered by the spin-down of the rapidly rotating, magnetized white dwarf. In 2020, LAMOST-J024048.51+195226.9 (J0240) was identified as a candidate eclipsing AE Aqr object, and we present three epochs of time-series spectroscopy that strongly support this hypothesis. We show that during the photometric flares noted by Thorstensen (2020) (arXiv:2007.09285), the half-width-at-zero-intensity of the Balmer and HeI lines routinely reaches a maximum of ~3000 km/s, well in excess of what is observed in normal cataclysmic variables. This is, however, consistent with the high-velocity emission seen in flares from AE Aqr. Additionally, we confirm beyond doubt that J0240 is a deeply eclipsing system. The flaring continuum, HeI and much of the Balmer emission likely originate close to the WD because they disappear during the eclipse that is centered on inferior conjunction of the secondary star. The fraction of the Balmer emission remaining visible during eclipse has a steep decrement and it is likely produced in the extended outflow. Most enticingly of all, this outflow produces a narrow P-Cyg absorption component for nearly half of the orbit, and we demonstrate that this scenario closely matches the outflow kinematics predicted by Wynn, King, & Horne (1997). While an important piece of evidence for the magnetic-propeller hypothesis -- a rapid WD spin period -- remains elusive, our spectra provide compelling support for the existence of a propeller-driven outflow viewed nearly edge-on, enabling a new means of rigorously testing theories of the propeller phenomenon.

description: Amine terminated molecules show well behaved conductance in the scanning tunneling microscope break-junction experimental measurements. We performed density functional theory based electron transport calculations to explain the nature of this phenomenon. We find that amines can be adsorbed only on apex Au atom, while thiolate group can be attached equally well to undercoordinated and clean Au surfaces. Our calculations show that only one adsorption geo metry is sterically and energetically possible for amine anchored junction whereas three different adsorption geometries with very distinct transport pro perties are almost equally probable for thiolate anchored junction. We calculated the conductance as a function of the junction stretching when the molecules are pulled by the scanning tunneling microscope tip from the Au electrode. Our calculations show that the stretching of the thiolate anchored junction during its formation is accompanied by significant electrode geometry distortio n. The amine anchored junctions exhibit very different behavior -- the electrode remains intact when the scan ning tunneling microscope tip stretches the junction.

description: Η παρούσα διπλωματική εργασία έχει σκοπό αφενός τη μελέτη των Συναξαριών ως αγιολογικών κειμένων και αφετέρου την κατασκευή ενός ιστοχώρου στον οποίο θα γίνεται η ψηφιακή παρουσίαση των προς μελέτη συναξαριών. Τα συναξάρια που μελετήθηκαν παρουσιάζουν δύο κοινά χαρακτηριστικά. Πρώτον αναφέρονται σε Αγίους που μαρτύρησαν σε νεαρή ηλικία και δεύτερον η μνήμη τους εορτάζεται μέσα στο α’ εξάμηνο του εκκλησιαστικού έτους (Σεπτέμβριος - Φεβρουάριος). Η βασική πρωτογενής πηγή που χρησιμοποιήθηκε ήταν τα βιβλία του Νικόδημου του Αγιορείτη «Συναξαριστής των 12 μηνών» και το «Νέο Μαρτυρολόγιο». Η παρουσίαση των συναξαριών έγινε σε ηλεκτρονική - διαδικτυακή μορφή, και συγκεκριμένα με τον ιστοχώρο: Αγιότητα και Νεότητα - Νεανικός Συναξαριστής (users.sch.gr/mvoule). Εδώ τα συναξάρια και η ανάλυσή τους παρουσιάζονται σε τρεις μορφές. Ο επισκέπτης συναντά το κείμενο του βίου, εικόνες των Αγίων αλλά και ηχογραφημένους τους βίους τους, ώστε να υπάρχει η δυνατότητα ακρόασης. Για τη σχεδίαση και υλοποίηση του ιστοχώρου χρησιμοποιήθηκε το Σύστημα Διαχείρισης Περιεχομένου (CMS) Joomla! το οποίο είναι ελεύθερο. Το όνομα χώρου στο Διαδίκτυο και τις ανάλογες υπηρεσίες, μας τα παρέχει το Πανελλήνιο Σχολικό Δίκτυο (ΠΣΔ)
description: This dissertation aims to the study of the “Synaxarion” as hagiological text and the construction of a web site in which our work will be presented in a digital form.The synaxarion studied have two common features. First, they refer to Saints who were martyred at an early age and the second is that their feast day is during the first half of the ecclesiastical year (September - February). The primary source used was the books of Nicodemus of Mount Athos "12 Months Synaxarion" and "New Martyrology". The presentation of the workshop was done in digital - online form, with the website named: Sanctity and Youth - Youthful Synaxarion (users.sch.gr/mvoule). Here the “Synaxarion” and their analysis are presented in three forms. The visitor can not only read the texts about Saints’ life and see their icons but also there is the possibility of listening the recorded texts. The Joomla Content Management System (CMS), which is free, was used to design and implement the website. The domain name on the Internet and the related services is provided to us by the Greek School Network (GSN)

description: Background: There is growing evidence that social and behavioral determinants of health (SBDH) play a substantial effect in a wide range of health outcomes. Electronic health records (EHRs) have been widely employed to conduct observational studies in the age of artificial intelligence (AI). However, there has been little research into how to make the most of SBDH information from EHRs. Methods: A systematic search was conducted in six databases to find relevant peer-reviewed publications that had recently been published. Relevance was determined by screening and evaluating the articles. Based on selected relevant studies, a methodological analysis of AI algorithms leveraging SBDH information in EHR data was provided. Results: Our synthesis was driven by an analysis of SBDH categories, the relationship between SBDH and healthcare-related statuses, and several NLP approaches for extracting SDOH from clinical literature. Discussion: The associations between SBDH and health outcomes are complicated and diverse; several pathways may be involved. Using Natural Language Processing (NLP) technology to support the extraction of SBDH and other clinical ideas simplifies the identification and extraction of essential concepts from clinical data, efficiently unlocks unstructured data, and aids in the resolution of unstructured data-related issues. Conclusion: Despite known associations between SBDH and disease, SBDH factors are rarely investigated as interventions to improve patient outcomes. Gaining knowledge about SBDH and how SBDH data can be collected from EHRs using NLP approaches and predictive models improves the chances of influencing health policy change for patient wellness, and ultimately promoting health and health equity.
