description: Η Φυσική Οργανική Ύλη (NOM) στα επιφανειακά ύδατα αποτελεί ένα ετερογενές μίγμα οργανικών ενώσεων που προέρχεται από διεργασίες που λαμβάνουν χώρα στα νερά ή στη λεκάνη απορροής. Η ΝΟΜ διαδραματίζει σπουδαίο ρόλο στους βιογεωχημικούς κύκλους των θρεπτικών συστατικών και του οξυγόνου, στη μεταφορά της οργανικής ύλης στα τροφικά πλέγματα καθώς και στην τύχη των οργανικών ενώσεων. Οι ανθρωπογενείς δραστηριότητες έχουν οδηγήσει σε μία αυξημένη εισροή θρεπτικών συστατικών και οργανικού φορτίου στα επιφανειακά υδάτινα συστήματα προκαλώντας έντονα φαινόμενα ευτροφισμού και υποβαθμίζοντας την ποιότητα των υδάτων. Στην εργασία αυτή εξετάζεται η χωρική και χρονική διακύμανση των επιπέδων της διαλυτής οργανικής ύλης (DOM) καθώς και των φασματοσκοπικών χαρακτηριστικών της στις λίμνες Βόλβη και Κορώνεια που ανήκουν στη λεκάνη της Μυγδονίας, σε 2 υδατορέματα της λεκάνης απορροής καθώς και στη λίμνη της Καστοριάς. Για το σκοπό αυτό πραγματοποιήθηκαν εποχικές δειγματοληψίες περιμετρικά αλλά και στο κέντρο κάθε λίμνης σε τρεις περιόδους. Στα δείγματα προσδιορίστηκε η συγκέντρωση του διαλυτού οργανικού άνθρακα (DOC) καθώς και το βιοαποικοδομήσιμο κλάσμα (BDOC). Εφαρμόσθηκαν διάφορες αναλυτικές τεχνικές όπως απορρόφηση UV-Vis, φθορισμομετρία, φασματοσκοπία NMR και FT-IR για τη διερεύνηση της σύστασης και των δομών της DOM. Έτσι, γίνεται ο χαρακτηρισμός της DOM ως προς το μοριακό μέγεθος, τη δομή, την ένταση φθορισμού και την περιεκτικότητα σε αλειφατικές/αρωματικές δομές. Τα αποτελέσματα συγκρίνονται μεταξύ των εξεταζόμενων υδάτινων συστημάτων
description: Natural Organic Matter (NOM) in surface waters is a heterogeneous mixture of organic compounds derived from processes occurring in the water or in the water’s basin. NOM plays an important role in the biogeochemical cycles of nutrients and oxygen, transport of organic matter in food chains and fate of organic compounds. Human activities have led to an increased inflow of nutrients and organic matter in surface water bodies causing intense eutrophication and degrading the water quality. Spatial and temporal variation of the level and the spectroscopic characteristics of the dissolved organic matter (DOM) in Lake Volvi, Lake Koronia and two streams which belong to the Mygdonia basin, and also in Lake of Kastoria have been evaluated. For this purpose, seasonal sampling was made around the lakes but also within each lake in 3 periods. DOC of the samples and the biodegradable fraction has been measured. Analytical techniques such as UV-Vis absorption, fluorimetry, NMR and FT-IR spectroscopy have been applied to investigate DOM’s composition. Thus, the DOM is characterized in terms of molecular size, structure, fluorescence intensity and aliphatic/aromatic content. The results are compared between the studied water bodies

description: Σκοπός της παρούσας μεταπτυχιακής εργασίας ήταν η αξιοποίηση της λιγνίνης που προέρχεται από την πολτοποίηση του ξύλου (λιγνοκυτταρινούχας βιομάζας) με την μέθοδο Kraft, είτε αυτούσιας είτε έπειτα από την τροποποίησή της με εποξειδικούς δακτύλιους, ως πρόσθετο πολυμερών. Η τροποποίηση της λιγνίνης με εποξειδικούς δακτύλιους επιτεύχθηκε με δύο διαφορετικές μεθόδους: α) σύνθεση με καταλύτη μεταφοράς φάσης (CTAB), β) σύνθεση με αλκοολικό (CH3OH) διάλυμα υδροξειδίου του νατρίου (ΝaOH). H τροποποίηση ήταν αποτελεσματικότερη μέσω της μεθόδου με αλκοολικό διάλυμα υδροξειδίου του νατρίου, σύμφωνα με τα αποτελέσματα χαρακτηρισμού με τις τεχνικές φασματοσκοπίας υπερύθρου FT-IR και πυρηνικού μαγνητικού συντονισμού 1H-NMR. Το συγκεκριμένο δείγμα ήταν και το θερμικά σταθερότερο (TGA, DTG). Παρασκευάστηκαν σύνθετα υλικά εποξειδικών πολυμερών με Kraft λιγνίνη και σύνθετα υλικά πολυμερών με εποξειδωμένη Kraft λιγνίνη. Τα τελευταία παρουσίασαν καλύτερες μηχανικές αντοχές σε σύγκριση με το καθαρό πολυμερές (EPON828/Jeffamine D-230). Η ικανότητα ενίσχυσης των ιδιοτήτων των εποξειδικών πολυμερών με τους διάφορους τύπους λιγνίνης μπορεί να συσχετιστεί με το μέγεθος των σωματιδίων και με την τροποποίηση τους με εποξειδικές ομάδες. Όσο μικρότερο είναι το μέγεθος των σωματιδίων, τόσο μεγαλύτερη είναι η διασπορά της λιγνίνης στο πολυμερές και μεγαλύτερη η ικανότητα ενίσχυσης, ενώ η τροποποίηση επιφέρει παρόμοια θετικά αποτελέσματα
description: The purpose of this postgraduate thesis was to utilize lignin originating from kraft pulping of wood (lignocellulosic biomass), either as it is or after its modification with epoxy rings, as a polymer additive. Functionalization of lignin with epoxy rings was achieved by two different methods: a) phase transfer catalyst (CTAB) synthesis; b) synthesis with alcoholic (CH3OH) sodium hydroxide solution (NaOH). The functionalization was more effective through the sodium hydroxide solution method, according to the characterization results with the FT-IR infrared spectroscopy and 1 H-NMR nuclear magnetic resonance techniques. This sample was also thermally stable (TGA, DTG). Composite materials of epoxy polymers with Kraft lignin and polymer composites with epoxidized Kraft lignin were also prepared. The latter exhibited better mechanical properties compared to pure polymer (EPON828 / Jeffamine D-230). The ability to enhance the properties of epoxy polymers with the different types of lignin can be correlated with the size of the particles and their modification with epoxy groups. The smaller the particle size, the greater the dispersion of lignin in the polymer and the greater the improvement of mechanical properties, the modification bringing about similar positive results

description: A novel hypersonic facility is proposed that will reproduce the high pressures and temperatures necessary for the accurate simulation of hypersonic flight conditions. It will provide sufficient test times for investigating unsteady, transient flow effects while maintaining high flow quality due to the absence of vitiation contaminants and shocks in the generating flow. An electrically preheated Ludwieg tube provides the initial means of heating while the piston-compression is used to further increase the pressure and temperature. Preliminary constraints on the design space for optimal operation are presented through the method of characteristics (MOC). Further characterization is performed with quasi-one-dimensional Euler computations. The MOC approach shows the optimal operating condition constrains the compression ratio and Ludwieg tube to nozzle exit diameter ratio, assuming proper simulation of flight conditions. The unsteady Euler computations predict the presence of  pressure oscillations generated during the piston-compression process. Methods are investigated to mitigate these oscillations.

Βασικοί άξονες συγκρότησης του νεοφιλελεύθερου πολίτη, ανεξαρτήτως συμμόρφωσης, είναι η έννοια της ελεύθερης επιλογής, η ευθύνη, η αυτονομία, η ισορροπία και η ενεργητική στάση απέναντι στις σωματικές δράσεις. Από την ανάλυση συνάγεται επίσης, ότι η έμφυλη ταυτότητα θεμελιώνεται στη βάση του διπόλου δύναμη(άνδρες)- αδυναμία (γυναίκες). Βασικό άξονας συγκρότησής της είναι η σεξουαλικότητα
description: The present study focuses on the detection of characteristics and practices which form the subjectivity of neoliberal citizen and gender identity, through the discourse of health and body. Data collected by unstructured interviews of twelve young men and women. Analysis used the principles of thematic interpretative analysis and Foucault’s model of power relations. Analysis indicated that neoliberal citizen, formed by the contrast among health and illness. Citizens are separated in the compliants and the refusers of health’s order. The concepts of free choice, responsibility, autonomy, balance and the active attitude towards body’s actions are the basic themes in the construction of neoliberal citizen through the discourse. Furthermore, analysis indicated that gender identities, based on the contrast among power (about men) and weakness (about women). Sexuality is the main theme in their construction

description: We show that in three-dimensional (3D) topological metals, a subset of the van Hove singularities of the density of states sits exactly at the transitions between topological and trivial gapless phases. We may refer to these as topological van Hove singularities. By investigating two minimal models, we show that they originate from energy saddle points located between Weyl points with opposite chiralities, and we illustrate their topological nature through their magnetotransport properties in the ballistic regime. We exemplify the relation between van Hove singularities and topological phase transitions in Weyl systems by analyzing the 3D Hofstadter model, which offers a simple and interesting playground to consider different kinds of Weyl metals and to understand the features of their density of states. In this model, as a function of the magnetic flux, the occurrence of topological van Hove singularities can be explicitly checked.

Subjects: subject: Information science

description: Information retrieval research for informal conversational settings differs in important ways from the more traditional goal of document retrieval. The goal of this research is to build an information retrieval test collection from informal conversational messages and to demonstrate the use of that collection to compare the retrieval effectiveness of some information retrieval systems. The test collection is

based on the Linguistic Data Consortium's collection of more than 8,000 English SMS (Short Message Service) conversations, which contain more than 120,000 individual messages. The collection is described, followed by a description of the processes for creating and collecting topics, performing relevance judgments, and establishing baseline results. The findings indicate that traditional approaches for building information retrieval test collections can reasonably be applied to preclustered SMS conversations, but that the process of creating relevance judgments is somewhat more challenging and thus the reliable detection of differences in system effectiveness is somewhat more complex.

description: Several approaches to the formulation of a fractional theory of calculus of "variable order" have appeared in the literature over the years. Unfortunately, most of these proposals lack a rigorous mathematical framework. We consider an alternative view on the problem, originally proposed by G. Scarpi in the early seventies, based on a naive modification of the representation in the Laplace domain of standard kernels functions involved in (constant-order) fractional calculus. We frame Scarpi's ideas within recent theory of General Fractional Derivatives and Integrals, that mostly rely on the Sonine condition, and investigate the main properties of the emerging variable-order operators. Then, taking advantage of powerful and easy-to-use numerical methods for the inversion of Laplace transforms of functions defined in the Laplace domain, we discuss some practical applications of the variable-order Scarpi integral and derivative.

Imitation and adaptation

description: The aim of this study is to examine the intertexual references to Homer’s epic in Lucretius’ De Rerum Natura. Luctetius concepts an epic poem in which atoms make aristeia. Moreover, I investigate how the homeric heroes are substituted by atoms in the lucretian epic. In my analysis, homeric intertextuality is proven to be an important and unambiguous element of the De Rerum Natura. Lucretius –a philosopher and poet- negotiates with Homer’s previous literary tradition. Integrating homeric tradition in his poem, Lucretius adapts it to epicurean content. However, the artistic quality of Homer’s narration is maintained. Finally, I examine why Lucretius echoes Homer in all realms of epicurean philosophy (epistemology, physics and ethics)

Στο έργο του, ο Λουκρήτιος αντικαθιστά του ομηρικούς ήρωες με τα δομικά στοιχεία του σύμπαντος. Επιπρόσθετα, η παρούσα μελέτη εστιάζει στις εικόνες στις οποίες η διακειμενική σχέση του Λουκρήτιου με τον Όμηρο είναι ευδιάκριτη και σαφής, και ερμηνεύει την κάθε περίπτωση. Επιπλέον, η μελέτη διερευνά τον τρόπο με τον οποίο ο φιλόσοφος-ποιητής εξασφαλίζει την ποιητικότητα τους έπους. Ο Λουκρήτιος κληρονομεί την προγενέστερη ομηρική παράδοση και την εξορθολογίζει, εντάσσοντάς την στο φιλοσοφικό του έπος. Ωστόσο, διατηρεί την ποιότητα της ομηρικής αφήγησης, διασφαλίζοντας τη λογοτεχνικότητα για το έργο του. Τέλος, η εργασία εξετάζει τον λόγο για τον οποίο ο Λουκρήτιος απηχεί τον Όμηρο σε όλους τους τομείς της επικούρειας φιλοσοφίας (γνωσιολογία, φυσική και ηθική)

description: For delay tolerant networks (DTNs), since there is no guarantee of end-to-end path from a source to a destination, routing protocols should make use of opportunistic contacts to deliver files. Although protocols employing network coding have been shown to achieve promising results in DTNs, they still suffer from redundant transmissions. An efficient stopping condition utilizing nullspace has been proposed recently. But more comprehensive studies are needed. In this thesis, a systematic research on effectiveness and efficiency of nullspace stopping condition is explored. We propose a novel algorithm to calculate nullspace. Using comprehensive simulations, we show that the benefits of nullspace stopping condition to network coding depend on scenarios. Moreover, performances may vary even in the same scenario with respect to the number and size of disseminated files. Finally explanations

about these phenomena are given out.

description: The recent observation of superconductivity in infinite-layer Nd$_{1-x}$Sr$_x$NiO$_2$ thin films has attracted a lot of attention, since this compound is electronically and structurally analogous to the superconducting cuprates. Due to the challenges in the phase stabilization upon chemical doping with Sr, we synthesized artificial superlattices of LaNiO$_3$ embedded in insulating LaGaO$_3$, and used layer-selective topotactic reactions to reduce the nickelate layers to LaNiO$_{2}$. Hole doping is achieved via interfacial oxygen atoms and tuned via the layer thickness. We used electrical transport measurements, transmission electron microscopy, and x-ray spectroscopy together with ab initio calculations to track changes in the local nickel electronic configuration upon reduction and found that these changes are reversible. Our experimental and theoretical data indicate that the doped holes are trapped at the interfacial quadratic pyramidal Ni sites. Calculations for electron-doped cases predict a different behavior, with evenly distributed electrons among the layers, thus opening up interesting perspectives for interfacial doping of transition metal oxides.

description: Green walls are technologies that provide benefits to the human, natural, and built environments including building shading and cooling, aesthetics, and habitat. Using natural ecosystems as templates, it should be possible to design green walls to provide enhanced ecological functions and play a role in urban reconciliation ecology. This thesis describes the design and performance of two types of green wall drawing inspiration from Mid-Atlantic ecosystems. The first, a wall modeled on Chesapeake Bay brackish marshes, was operated in the Baltimore Harbor for five months and successfully replicated some conditions of wetlands including supporting the growth of native macrophytes throughout the growing season. Notably, this model is the first functional green wall designed for an urban waterfront. The second design tested native grass survival in a dry grasslands-inspired green wall model. In this model, which was moisture-limited with a very shallow substrate, both planted grass species gave way to an invasion of volunteer species.

description: The Eurasian space is geographically, culturally, historically and mentally linked to Asia and Europe. This area is characterised by global regionalisation, namely the increase of national and regional competitiveness in the globalised economy. The theory of Eurasianism evolved and received a radically new content, through articles and speeches by the leaders of Russia, Kazakhstan and Belarus. They communicated their vision of the Eurasian Economic Union (EAEU), by bypassing the failed integration attempts during the past. The goal is a realistic economic entity that would help modernise the economies of its five-member states, with the prospect of becoming an organic part of the new global economic architecture. The Treaty establishing the EAEU in 2014, following the EU's footsteps, is the cornerstone of this effort, by establishing institutions and by defining objectives and policies. In its years of operation, EAEU, as an international organization, has made progress and aims to overcome obstacles such as the hegemonic policies of Russia, in order to come closer with the EU and to exploit China's project "One Belt, One Road" (OBOR)

description: Public Private Partnerships (P3’s) are a relatively new project delivery method. In reaction to the increased attention to this delivery method, the Federal Highway Administration has begun to enhance its existing P3-VALUE toolkit, an educational toolkit which demonstrates the potential benefits of utilizing a Public Private Partnership over a traditional method like Design Bid Build for transportation projects. The toolkit utilizes assumptions about P3 project characteristics to build the scenarios for its analyses. Unfortunately, there is a significant lack of data which would serve to justify assumptions made about improved P3 quality performances. Furthermore, there is a basic lack of knowledge regarding what data is even available to make certain assumptions. The intent of this thesis is to identify what data can be collected, what data can be shared, and to determine what data can be expected to be reliably available, and not subject to proprietary rights, for future analysis regarding the improved P3 quality performance.

description: We study superconducting transition temperature ($T_c$) of oxygen-doped double-layer high-temperature superconductors YBa$_2$Cu$_3$O$_{6+δ}$ (0 $\le$ $δ$ $\le$ 1) as a function of the oxygen dopant concentration ($δ$) and planar hole-doping concentration ($P_{pl}$). We find that $T_c$, while clearly influenced by the development of the chain ordering as seen in the $T_c$ $vs.$ $δ$ plot, lies on a universal curve originating at the critical hole concentration ($P_c$) = 1/16 in the $T_c$ $vs.$ $P_{pl}$ plot. Our analysis suggests that the universal behavior of $T_c$($P_{pl}$) can be understood in terms of the competition and collaboration of chemical-phases and electronic-phases that exist in the system. We conclude that the global superconductivity behavior of YBa$_2$Cu$_3$O$_{6+δ}$ as a function of doping is electronically driven and dictated by pristine electronic phases at magic doping numbers that follow the hierarchical order based on $P_c$, such as 2 $\times$ $P_c$, 3 $\times$ $P_c$ and 4 $\times$ $P_c$. We find that there are at least two intrinsic electronic superconducting phases of $T_c$ = 60 K at 2 $\times$ $P_c$ = 1/8 and $T_c$ = 90 K at 3 $\times$ $P_c$ = 3/16.

description: H παρούσα μελέτη εξέτασε την αποτελεσματικότητα δύο αυτοδιαχειριζό-μενων παρεμβάσεων, που αναπτύχθηκαν για τους σκοπούς της έρευνας και απέβλεπαν στην ενίσχυση της ευζωίας των ενηλίκων μέσω της καλλιέργειας συγχωρητικών δεξιοτήτων. Συμμετείχαν, συνολικά, 11 άνδρες και 31γυναίκες ηλικίας 34-80 ετών. Οι συμμετέχοντες κλήθηκαν να συμπληρώσουν ερωτη-ματολόγια για τη μέτρηση της ψυχικής άνθησης, των συγχωρητικών δεξιοτήτων και των κινήτρων αποφυγής εκδίκησης και καλοσύνης. Στη συνέχεια, διαχωρίστηκαν τυχαία σε δύο ομάδες εξισωμένες ως προς την ηλικία, το φύλο και το μορφωτικό επίπεδο και παρακολούθησαν η μια τη Γενική, και η άλλη την εμπλουτισμένη με στοιχεία από την Ορθόδοξη Παράδοση παρέμβαση. Οι παρεμβάσεις περιλάμβαναν έξι φάσεις/βήματα προς τη συγχώρηση. Για την ολοκλήρωσή τους εφαρμόστηκε συνδυασμός ατομικής συνεδρίας και προσωπικής μελέτη. Η διαδικασία ολοκληρώ-θηκε σε μία εβδομάδα. Στο τέλος της παρέμβασης και δύο εβδομάδες μετά την ολοκλήρωσή της, οι συμμετέχοντες κλήθηκαν να συμπληρώσουν εκ νέου τα ίδια ερωτηματολόγια. Τα αποτελέσματα έδειξαν ότι οι συγχωρητικές δεξιότητες και τα επίπεδα της ευζωίας ενισχύθηκαν και στις δύο παρεμβάσεις και σημαντικά περισσότερο στην Ορθόδοξη. Αναδείχθηκε η υπεροχή της Ορθόδοξης προσέγγισης στη μείωση των αρνητικών συναισθημάτων και στην προώθηση των επιμέρους διαστάσεων της ευζωίας σε διάρκεια χρόνου. Διερευνήθηκαν πιθανοί μηχανισμοί που ερμηνεύουν την αποτελεσματικότητα των παρεμβάσεων
description: The present study examined the efﬁcacy of two self-guided interventions, which aimed at enhancing adults’ wellbeing through the cultivation of forgiveness skills. A total of 11 men and 31 women aged 34-80 years were involved. The participants were asked to complete questionnaires measuring the sense of wellbeing, the trait of forgiveness, and avoidance, revenge, and benevolence motivations. Subsequently, they were randomly divided into two groups which were matched in age, gender and educational level, and one group followed the General, and the other one the Orthodox-Tradition-Enhanced Intervention. The two interventions included six steps towards forgiveness. For their completion a combination of individual sessions and a personal study were implemented. The process was completed within one week. Participants were also asked to complete the same questionnaires immediately after the intervention as well as two weeks after the intervention (follow-up measurement). The results showed that forgiveness skills and subjective wellbeing were strengthened via both interventions and significantly more in the Orthodox. The primacy of the Orthodox approach has been demonstrated to reduce negative emotions and to promote a sense of wellbeing over time. Possible mechanisms for the effectiveness of the intervention are discussed

description: The Cern Axion Solar Telescope (CAST) is in operation and taking data since 2003. The main objective of the CAST experiment is to search for a hypothetical pseudoscalar boson, the axion, which might be produced in the core of the sun. The basic physics process CAST is based on is the time inverted Primakoff effect, by which an axion can be converted into a detectable photon in an external electromagnetic field. The resulting X-ray photons are expected to be thermally distributed between 1 and 7 keV. The most sensitive detector system of CAST is a pn-CCD detector combined with a Wolter I type X-ray mirror system. With the X-ray telescope of CAST a background reduction of more than 2 orders off magnitude is achieved, such that for the first time the axion photon coupling constant g_agg can be probed beyond the best astrophysical constraints g_agg < 1 x 10^-10 GeV^-1.

description: Explaining the decisions of models is becoming pervasive in the image processing domain, whether it is by using post-hoc methods or by creating inherently interpretable models. While the widespread use of surrogate explainers is a welcome addition to inspect and understand black-box models, assessing the robustness and reliability of the explanations is key for their success. Additionally, whilst existing work in the explainability field proposes various strategies to address this problem, the challenges of working with data in the wild is often overlooked. For instance, in image classification, distortions to images can not only affect the predictions assigned by the model, but also the explanation. Given a clean and a distorted version of an image, even if the prediction probabilities are similar, the explanation may still be different. In this paper we propose a methodology to evaluate the effect of distortions in explanations by embedding perceptual distances that tailor the neighbourhoods used to training surrogate explainers. We also show that by operating in this way, we can make the explanations more robust to distortions. We generate explanations for images in the Imagenet-C dataset and demonstrate how using a perceptual distances in the surrogate explainer creates more coherent explanations for the distorted and reference images.

description: Using 6.32 fb$^{-1}$ of $e^+e^-$ collision data collected by the BESIII detector at the center-of-mass energies between 4.178 and 4.226 GeV,~an amplitude analysis of the $D^{+}_{s}\rightarrow K^{0}_{S}K^{-}π^{+}π^{+}$ decays is performed for the first time to determine the intermediate-resonant contributions. The dominant component is the $D_s^+ \to K^*(892)^+\overline{K}^*(892)^0$ decay with a fraction of $(40.6\pm2.9_{\rm stat}\pm4.9_{\rm sys})$%. Our results of the amplitude analysis are used to obtain a more precise measurement of the branching fraction of the $D^{+}_{s}\rightarrow K^{0}_{S}K^{-}π^{+}π^{+}$ decay, which is determined to be $(1.46\pm0.05_{\rm stat}\pm0.05_{\rm sys}$)%.

description: We analyze families of particle detector models that linearly couple to different kinds of fermionic and bosonic fields. We also study the response of these detectors to particle and anti-particle excitations of the field. We propose a simple linear complex scalar particle detector model that captures the fundamental features of fermionic field detectors similarly to how the Unruh-DeWitt model captures the features of the light matter interaction. We also discuss why we do not need to limit ourselves to quadratic models commonly employed in past literature. Namely, we provide a physically motivated mechanism that restores U(1) symmetry in these linear complex models.

description: Utilizing a complete Lorentz-covariant and local-gauge-invariant formulation, we discuss graphene response to arbitrary external electric field. The relation, which is called as Kramers-Kr(\ddot{o})nig relation in the paper, between imaginary part and real part of ac conductivity is given. We point out there exists an ambiguity in the conductivity computing, attributed to the wick behavior at ultraviolet vicinity. We argue that to study electrical response of graphene completely, non-perturbational contribution should be considered.

Machine learning based energy-free structure predictions of molecules (closed and open-shell), transition states, and solids

description: The computational prediction of atomistic structure is a long-standing problem in physics, chemistry, materials, and biology. Within conventional force-field or {\em ab initio} calculations, structure is determined through energy minimization, which is either approximate or computationally demanding. Alas, the accuracy-cost trade-off prohibits the generation of synthetic big data records with meaningful energy based conformational search and structure relaxation output. Exploiting implicit correlations among relaxed structures, our kernel ridge regression model, dubbed Graph-To-Structure (G2S), generalizes across chemical compound space, enabling direct predictions of relaxed structures for out-of-sample compounds, and effectively bypassing the energy optimization task. After training on constitutional and compositional isomers (no conformers) G2S infers atomic coordinates relying solely on stoichiometry and bond-network information as input (Our numerical evidence includes closed and open shell molecules, transition states, and solids). For all data considered, G2S learning curves reach mean absolute interatomic distance prediction errors of less than 0.2 Å for less than eight thousand training structures -- on par or better than popular empirical methods. Applicability test of G2S include meaningful structures of molecules for which standard methods require manual intervention, improved initial guesses for subsequent conventional {\em ab initio} based relaxation, and input for structural based representations commonly used in quantum machine learning models, (bridging the gap between graph and structure based models).

Συνολικά, εξετάστηκε το περιεχόμενο της παραπάνω έννοιας, η διαδικασία απόκτησης της ιδιότητας του προσώπου από τον πράττοντα και τα ζητήματα που προκύπτουν από το ζήτημα αυτό. Αρχικά, παρουσιάστηκαν αναλυτικά τα χαρακτηριστικά που οφείλει να διαθέτει κανείς ώστε να ονομαστεί πρόσωπο. Στην συνέχεια, αναλύθηκε η διαδικασία της απόκτησης της ιδιότητας του προσώπου, κυρίως από χρονική άποψη. Τέλος, αναπτύχθηκαν οι βιοηθικού τύπου προεκτάσεις που προκύπτουν από το ζήτημα της ταυτότητας, που συνίστανται σε ζητήματα περί των δικαιωμάτων του ατόμου και σε πράξεις του τερματισμού της ζωής
description: The aim of the present thesis was the study of the person’s identity in the Stoic philosophy. I examined the meaning of the word identity, how the subject gets its own identity and what kind of problems this creates, as far as bioethics concerned. Firstly, I analyzed what it means to have an identity. Furthermore, I examined the way that someone could start having his own identity and specifically, which is the right age in order to start being an individual. I also analyzed the bioethics which arises from the meaning of identity in Stoics

description: Background and rationale: Heart failure (HF), which is an emerging public health issue, adversely affects the strained health system in India. The potential adverse impact of HF on the economic well-being of affected individuals and their families is narrated in various anecdotal reports. Further, HF is known to push the affected individuals and their dependents into poverty. However, there is limited research quantifying how HF impacts the economic well-being of households from the low and middle-income countries. Methods: We describe the methods of a detailed economic impact assessment of HF at the household level in India. The economic impact study in HF is initiated across 20 centres in India. The selected centres represent different regions in India stratified based on the prevailing stage of epidemiological transition levels (ETLs). We will collect data from 1800 patients with acute decompensated HF and within 6-15 months of follow-up from the time of initial admission. The data that we intend to collect will consist of a) household healthcare expenditure including out-of-pocket expenditure, b) financing mechanisms used by households and (c) the impoverishing effects of health expenditures including distress financing and catastrophic health expenditure. Trained staff at each centre will collect relevant data by using a validated and structured interview schedule. The study will have 80% power, after accounting for five percent non-response rate, to test eight percent difference in primary outcome (proportion of families under distress financing) between different ETLs. Impact: The results from the study will help policy makers in understanding the micro-economic impact of HF in India and aid in allocation of appropriate resources for prevention and control of HF.

description: Recently normalizing flows (NFs) have demonstrated state-of-the-art performance on modeling 3D point clouds while allowing sampling with arbitrary resolution at inference time. However, these flow-based models still require long training times and large models for representing complicated geometries. This work enhances their representational power by applying mixtures of NFs to point clouds. We show that in this more general framework each component learns to specialize in a particular subregion of an object in a completely unsupervised fashion. By instantiating each mixture component with a comparatively small NF we generate point clouds with improved details compared to single-flow-based models while using fewer parameters and considerably reducing the inference runtime. We further demonstrate that by adding data augmentation, individual mixture components can learn to specialize in a semantically meaningful manner. We evaluate mixtures of NFs on generation, autoencoding and single-view reconstruction based on the ShapeNet dataset.
