description: Η παρούσα διπλωματική εργασία αφορά την υπολογιστική μελέτη της χωρητικής υπερθερμίας με τη χρήση ρεαλιστικών μοντέλων. Στο πρώτο κεφάλαιο γίνεται μια γενική εισαγωγή στην θεραπεία του καρκίνου με τη χρήση της υπερθερμίας, αλλά και της χωρητικής υπερθερμίας πιο συγκεκριμένα. Στο δεύτερο κεφάλαιο, παρουσιάζονται οι λεπτομέρειες κατασκευής των ρεαλιστικών μοντέλων που χρησιμοποιήθηκαν κατά το υπολογιστικό κομμάτι της εργασίας αυτής. Στο τρίτο κεφάλαιο, παρατίθεται η αριθμητική τεχνική που χρησιμοποιήθηκε για τον υπολογισμό των αποτελεσμάτων, καθώς και οι ρυθμίσεις που ορίστηκαν μέσα στην πλατφόρμα των προσομοιώσεων. Τέλος στο τέταρτο κεφάλαιο της εργασίας, παρουσιάζονται τα αποτελέσματα της υπολογιστικής μελέτης, μέσα από πίνακες και εικόνες. Πιο συγκεκριμένα μελετήθηκε η κατανομή του SAR (Specific Absorption Rate), για διαφορετικές αγωγιμότητες των υδάτινων στρωμάτων, για διαφορετικές θέσεις και αριθμό των ηλεκτροδίων και για διαφορετικές αγωγιμότητες των ιστών. Επίσης μελετήθηκε η επίδραση της αντικατάστασης του ιστού του στήθους με εμφυτεύματα σιλικόνης στην κατανομή του SAR στο ήπαρ, και εγινε υπολογισμός της μεταβολής της θερμοκρασίας που μπορεί να προκαλέσει ένα σύστημα χωρητικής υπερθερμίας. Οι πίνακες περιέχουν τις τιμές του SAR για το ήπαρ και τον καρκίνο του ήπατος, καθώς και τις κανονικοποιημένες τιμές αυτών ώστε να είναι δυνατή η σύγκριση των αποτελεσμάτων, καθώς τα σχήματα τα οποία παρατίθενται απεικονίζουν την κατανομή του SAR στους παραπάνω ιστούς
description: The present thesis concerns the computational study of capacitive hyperthermia with realistic models. In the first chapter, a general introduction in cancer treatment with the use of hyperthermia, as well as an introduction in RF capacitive hyperthermia, are presented. In the second chapter, the details of the models used in the computational part of the study, are mentioned. In the third chapter, we describe the numerical technique which has been used for the calculations of the results, and the settings selected inside the simulation platform. Finally, in the fourth chapter of this study, the results are presented in the form of appropriate tables and figures. More specifically, the distribution of SAR (Specific Absorption Rate) for different values of electric conductivity of the fluid contained within the water boluses, for different locations and number of electrodes and different electric conductivity for the tissues, was studied. The effect of the replacement of breast fat with silicone breast implants in the distribution of SAR, was also studied, and we calculated the maximum increase of temperature that a capacitive applicator can induce. Tables contain the results of SAR for liver and liver cancer, as well as the normalized values of them, for a comparison of results to be possible, while figures show the distribution of SAR for the above tissues

Αυτό αποσκοπεί στην προσπάθεια της μείωσης των εκπομπών διοξειδίου του άνθρακα, προκειμένου να προστατευτούν τα σημαντικότερα αγαθά που διαθέτει ο άνθρωπος, η υγεία και το περιβάλλον. Υπάρχουν χώρες που έχουν κάνει σημαντικά βήματα για τη πάταξη αυτού του φαινόμενου, ενώ κάποια άλλα δεν έχουν κάνει την παραμικρή προσπάθεια σκεφτόμενοι μονάχα το προσωπικό τους συμφέρον. Συνεπώς ο σκοπός της κάθε χώρας για υψηλότερη οικονομική μεγέθυνση, ανεξαρτήτως κόστους μπορεί να λογιστεί ως μια από τις αιτίες της μη εφαρμογής ανανεώσιμων πηγών ενεργείας.

description: In recent years, efforts have been increasingly made by states to establish the consumption of renewable energy sources in their day-to-day operations. This is aimed to success in reducing carbon dioxide emissions in order to protect the most important goods for people, health and the environment. There are countries that have taken important steps to counter this phenomenon, while some countries have not made the slightest effort by thinking only of their own personal interest. Therefore the purpose of each country for highest economic growth, regardless of cost, can be counted as one of the causes of non-renewable energy consumption. The ultimate goal of this diploma thesis is to investigate a particular group of countries, the center and Eastern Europe, in order to obtain a safe conclusion for the dynamic interaction of the following variables: 1) life expectancy, 2) consumption of renewable energy sources, 3) consumption of non-renewable energy sources, 4) economic growth and 5) carbon dioxide emissions

description: Supersolidity -- a quantum-mechanical phenomenon characterized by the presence of both superfluidity and crystalline order -- was initially envisioned in the context of bulk solid helium, as a possible answer to the question of whether a solid could have superfluid properties. While supersolidity has not been observed in solid helium (despite much effort), ultracold atomic gases have provided a fundamentally new approach, recently enabling the observation and study of supersolids with dipolar atoms. However, unlike the proposed phenomena in helium, these gaseous systems have so far only shown supersolidity along a single direction. By crossing a structural phase transition similar to those occurring in ionic chains, quantum wires, and theoretically in chains of individual dipolar particles, we demonstrate the extension of supersolid properties into two dimensions, providing an important step closer to the bulk situation envisioned in helium. This opens the possibility of studying rich excitation properties, including vortex formation, as well as ground-state phases with varied geometrical structure in a highly flexible and controllable system.

Generalized Squashing Factors for Covariant Description of Magnetic Connectivity in the Solar Corona
Creators: name: Titov, V. S.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The study of magnetic connectivity in the solar corona reveals a need to generalize the field line mapping technique to arbitrary geometry of the boundaries and systems of coordinates. Indeed, the global description of the connectivity in the corona requires the use of the photospheric and solar wind boundaries. Both are closed surfaces and therefore do not admit a global regular system of coordinates. At least two overlapping regular systems of coordinates for each of the boundaries are necessary in this case to avoid spherical-pole-like singularities in the coordinates of the footpoints. This implies that the basic characteristic of magnetic connectivity - the squashing degree or factor $Q$ of elemental flux tubes (Titov et al., 2002) - must be rewritten in covariant form. Such a covariant expression of $Q$ is derived in this work. The derived expression is very flexible and highly efficient for describing the global magnetic connectivity in the solar corona. In addition, a general expression for a new characteristic $Q_\perp$ which defines a squashing of the flux tubes in the directions perpendicular to the field lines is determined. This new quantity makes it possible to filter out the quasi-separatrix layers whose large values of $Q$ are caused by a projection effect at the field lines nearly touching the photosphere. Thus, the value $Q_\perp$ provides a much more precise description of the volumetric properties of the magnetic field structure. The difference between $Q$ and $Q_\perp$ is illustrated by comparing their distributions for two configurations, one of which is the Titov-Demoulin (1999) model of a twisted magnetic field.

Evanescent wave interference and the total transparency of a warm high-density plasma slab

description: It is shown that an overcritical density plasma slab can be totally transparent to a \textit{p}-polarized obliquely incident electromagnetic wave. High transparency is achieved due to the interference of the evanescent waves in the subcritical region. The transmission coefficient has the resonant character due to the excitation of a plasma surface mode (plasmon-polariton). It is crucial that two evanescent waves have certain phase shift to provide non-zero energy flux through non-transparent region. The required phase shift is obtained at the exact resonance and corresponds to the absolute transparency. In a warm plasma case, the excitation of the propagating longitudinal (electrostatic) modes becomes possible. We demonstrate that these longitudinal excitations facilitate the total transparency of an opaque plasma slab creating additional resonances in the transmission property of the system.
Density of States, Entropy, and the Superconducting Pomeranchuk Effect in Pauli-Limited Al Films

description: We present low temperature tunneling density of states measurements of Pauli-limited Al films in which the Zeeman and orbital contributions to the critical field are comparable. We show that films in the thickness range of 6-7 nm exhibit a reentrant parallel critical field transition which is associated with a high entropy superconducting phase, similar to the high entropy solid phase of 3He responsible for the Pomeranchuk effect. This phase is characterized by an excess of states near the Fermi energy so long as the parallel critical field transition remains second order. Theoretical fits to the zero bias tunneling conductance are in good agreement with the data well below the transition but theory deviates significantly near the transition. The discrepancy is a consequence of the emergence of e-e interaction correlations as one enters the normal state.

description: Με την βιοκλιματική αρχιτεκτονική επιδιώκεται στο μεγαλύτερο δυνατό βαθμό η δέσμευση φυσικής ενέργειας που παράγεται από ήπιες και ανανεώσιμες πηγές ενέργειας, που θεωρούνται πρακτικά ανεξάντλητες. Η δέσμευση της ηλιακής ακτινοβολίας κατά τη χειμερινή περίοδο και η μετατροπή της σε θερμότητα που θα συνεισφέρει στη θέρμανση του κτιρίου, όπως και η αξιοποίηση του ανέμου κατά τη θερινή περίοδο που θα συμβάλλει στο δροσισμό των χώρων του, παίζουν σημαντικό ρόλο στη βιοκλιματική αρχιτεκτονική. Από την άλλη πλευρά όμως εξίσου σημαντική είναι και η προστασία του κτιρίου από την υπερθέρμανση το καλοκαίρι και από τους ισχυρούς ανέμους το χειμώνα. Τα κύρια στοιχεία του βιοκλιματικού σχεδιασμού είναι τα παθητικά συστήματα θέρμανσης, τα ενεργειακά συστήματα και τα παθητικά συστήματα φυσικού δροσισμού. Χάρη στην ραγδαία αύξηση της επιλογής βιοκλιματικής αρχιτεκτονικής, αναζητούνται συνεχώς νέοι τρόποι βελτίωσης της κατασκευής ως προς τα δομικά της στοιχεία αλλά και ως προς την χρήση πιο καινοτόμων δομικών υλικών. Μερικές απ’ αυτές τις νέες λύσεις έχουν εφαρμογή σε διάφορες κατοικίες σε παγκόσμια κλίμακα και τα αποτελέσματα τους είναι ακόμα προς έρευνα.
description: Bioclimatic architecture seeks to the fullest extent possible the capture of natural energy produced by mild and renewable energy sources, which are considered practically inexhaustible. The commitment of solar radiation during the winter period and its transformation into heat that will contribute to the heating of the building, as well as the use of wind during the summer period, which will contribute to the cooling of its premises, play an important role in bioclimatic architecture. On the other hand, however, it is equally important to protect the building from overheating in the summer and from strong winds in the winter. The main elements of the bioclimatic design are passive heating systems, energy systems and passive natural cooling systems. Thanks to the rapid increase in the choice of bioclimatic architecture, new ways of improving construction are being constantly sought in terms of structural elements, but also for the use of more innovative building materials. Some of these new solutions are applicable to various residential developments worldwide and their results are still for research.

description: Magnetic skyrmion, i.e. a topologically stable swirling spin texture, appears as a particle-like object in the two-dimensional (2D) systems, and has recently attracted attention as a candidate of novel information carrier. In the real three-dimensional (3D) systems, a skyrmion is expected to form a string structure along an extra dimension, while its experimental identification has rarely been achieved. Here, we report the direct visualization of 3D shape of individual skyrmion strings, for the recently discovered room-temperature skyrmion-hosting noncentrosymmetric compound Mn1.4Pt0.9Pd0.1Sn. For this purpose, we have newly developed the magnetic X-ray tomography measurement system that can apply magnetic field, which plays a key role on the present achievement. Through the tomographic reconstruction of the 3D magnetization distribution based on the transmission images taken from various angles, a genuine skyrmion string running through the entire thickness of the sample, as well as various defect structures such as the interrupted and Y-shaped strings, are successfully identified. The observed point defect may represent the emergent magnetic monopole, as recently proposed theoretically. The present tomographic approach with tunable magnetic field paves the way for the direct visualization of the structural dynamics of individual skyrmion strings in the 3D space, which will contribute to the better understanding of the creation, annihilation and transfer process of these topological objects toward the potential device applications.

description: The purpose of this work is to design networks using GNS3 software. This will be done by describing and executing networking exercises on the GNS3 program. These exercises are based on simple, daily or more specialized issues, which could be met in real network topologies. Before analyzing the exercises will be introduced into GNS3 network simulation software, as well as concepts such as networks and some configurations of them, network protocols and network devices. The thesis is divided into three parts, the first two theoretical and the third practical. In detail the theoretical part of the networks, the theoretical part of the software and the exercises. Initially, an introductionwill be made to the theoretical part of the networks and their related elements so that the reader can understand the networks and be able to solve the corresponding exercises. The second part introduces the GNS3 program to adapt and familiarize you with the exercise tool. In conclusion, with the combination of all the above, a description of the issues of the exercises and then the presentation of the solution of the exercises, following concrete steps, will be presented in a simplistic and understandable way

description: In this paper, we propose a class of high breakdown point estimators for the linear regression model when the response variable contains censored observations. These estimators are robust against high-leverage outliers and they generalize the LMS (least median of squares), S, MM and $τ$-estimators for linear regression. An important contribution of this paper is that we can define consistent estimators using a bounded loss function (or equivalently, a redescending score function). Since the calculation of these estimators can be computationally costly, we propose an efficient algorithm to compute them. We illustrate their use on an example and present simulation studies that show that these estimators also have good finite sample properties.

description: Στόχος της παρούσας εργασίας είναι να εντοπίσει τους προσδιοριστικούς παράγοντες του χρηματιστηριακού δείκτη. Στους προσδιοριστικούς αυτούς παράγοντες συμπεριλαμβάνονται: η βιομηχανική παραγωγή, το μακροχρόνιο πραγματικό επιτόκιο, το άνοιγμα του εμπορίου, και το ποσοστό του κέρδους. Η ανάλυση διεξάγεται χρησιμοποιώντας ετήσια στοιχεία 15 οικονομικά αναπτυγμένων χωρών για το διάστημα 1985-2015. Η εκτίμηση του υποδείγματος γίνεται με τη μεθοδολογία σταθερών επιδράσεων τόσο για το διάστημα 1985-2015 όσο και για τα επιμέρους διαστήματα 1985-2000, 2000-2015 αλλά και 1985-2006, 2006-2015 με σκοπό να παρουσιαστεί ο τρόπος με τον οποίο διαμορφώνεται η επίδραση των προσδιοριστικών παραγόντων στον χρηματιστηριακό δείκτη σε περιόδους χρηματιστηριακής και οικονομικής κρίσης, αντίστοιχα. Επιπρόσθετα, για τον υπολογισμό της μακροχρόνιας σχέσης ισορροπίας των μεταβλητών χρησιμοποιείται η μεθοδολογία PMG/ARDL. Από τα αποτελέσματα των δυο μεθοδολογιών προκύπτει ότι η επίδραση των ερμηνευτικών μεταβλητών στην εξαρτημένη στο σύνολο της περιόδου και στις περισσότερες υποπεριόδους είναι θετική εκτός από αυτή του επιτοκίου η οποία είναι αρνητική. Μεταξύ των προσδιοριστικών παραγόντων ξεχωρίζει το ποσοστό κέρδους (δείκτης κερδοφορίας) το οποίο βρίσκεται θετικό σε όλες τις περιπτώσεις. Τέλος, από τη μεθοδολογία PMG/ARDL επιβεβαιώνεται η ύπαρξη μακροχρόνιας σχέσης ισορροπίας
description: The aim of this paper is to identify the determinants of the stock market index. These determinants include: industrial production, long-term real interest rate, trade opening, and profit rate. The analysis is conducted using annual figures of 15 economically developed countries for the period 1985-2015. The estimation of the model is based on Fixed Effect methodology for both 1985-2015 and for the sub periods 1985-2000, 2000-2015 and 1985-2006, 2006-2015 in order to illustrate the way in which the influence of determinants on the stock market index during periods of stock market and financial crisis, changes respectively. In addition, the PMG / ARDL methodology is used to calculate the long-term equilibrium balance of variables. The results of the two methodologies show that the effect of the explanatory variables on the subordinate in the whole period and in most sub periods is positive except for the interest rate which is negative. Among the determinants is the profit rate (profitability index) that is positive in all cases. Finally, the PMG / ARDL methodology confirms the existence of a long-term equilibrium relationship

description: Public coastal access is a growing issue in coastal management, particularly as both environmental changes and increased coastal development threaten existing public coastal access points around the country. This has implications both economically and on non-economic factors such as individual and community well-being. Through a mixed-methods case study of coastal users in Rhode Island (n = 200 surveys and n = 29 interviews), this study explores the concept of attachment to coasts as a specific type of place attachment by identifying Coastal Place Attachment (CPA) as a concept, developing a quantitative index to measure CPA, and qualitatively describing the value that coastal attachment brings to well-being. Results show that individuals do have a unique attachment to coastal environments that is not transferable to other natural areas, although it may be generalizable to other coastal areas. We also document how this attachment provides important contributions to psychological, physical, and social well-being. Implications for coastal access management are discussed.

description: The phenomenon of shadowing of nuclear structure functions at small values of Bjorken-$x$ is analyzed. First, multiple scattering is discussed as the underlying physical mechanism. In this context three different but related approaches are presented: Glauber-like rescatterings, Gribov inelastic shadowing and ideas based on high-density Quantum Chromodynamics. Next, different parametrizations of nuclear partonic distributions based on fit analysis to existing data combined with Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution, are reviewed. Finally, a comparison of the different approaches is shown, and a few phenomenological consequences of nuclear shadowing in high-energy nuclear collisions are presented.

Συγκεκριμένα καλούνται τα παιδιά να αναπαραστήσουν τον εαυτό τους και στη συνέχεια οι γονείς τα παιδιά τους. Μέσω της ανάλυσης των αναπαραστάσεων αυτών θα αναζητηθεί η συνοχή ανάμεσα στις δύο αναπαραστάσεις καθώς και η διεργασία εσωτερική αφήγησης/παρουσίασης του γονέα για το παιδί του
description: The aim of the present thesis was to present the type of relationship between the parents and the child through an experiential activity. The attachment between the child and the care person (the parent) is very important for its psycho-emotional development. In the present study the type of attachment will be presented through the representations of children and parents in art activities. The children are invited to represent their selves and then the parents to represent the children. Through the analysis of these representations the cohesion between the representations will be investigated as well as the process of the inner narrative of parent for his/her child

Διερευνήθηκαν μια σειρά από παράγοντες όπως το φύλο, το επίπεδο εκπαίδευσης, ο τομέας εργασίας, τα χρόνια προϋπηρεσίας, το εάν οι νηπιαγωγοί είχαν επαφή με παιδιά με διαταραχές της ανάπτυξης, το εάν οι νηπιαγωγοί είχαν γνώσεις για τον αυτισμό σε σχέση με την ανίχνευση πιθανών διαταραχών ανάπτυξης και με τις ενέργειες στις οποίες προβαίνουν οι νηπιαγωγοί σε περίπτωση ανίχνευσης των διαταραχών ανάπτυξης. Όσον αφορά στα αποτελέσματα, οι δύο σημαντικές μεταβλητές για την ανίχνευση και για τις ενέργειες των νηπιαγωγών σε περίπτωση ανίχνευσης αποτελούν το αν είχαν παιδιά με διαταραχή στο φάσμα του αυτισμού στην τάξη και η εκπαίδευση τους σε θέματα διάχυτων αναπτυξιακών διαταραχών
description: The aim of this quantitative research is to investigate the perceptions of preschool teachers about the early identification and referral of developmental disorders in preschool children. This is a quantitative survey using a questionnaire. A number of factors have been investigated, like gender, level of education, field of work, years of service, whether the teachers had contact with children with developmental disabilities, whether the teachers had knowledge of autism spectrum disorders were investigated in relation to the detection of possible developmental disorders and in relation to the actions taken by preschool teachers in case of detecting developmental disorders. In terms of the results, the two important factors for the detection and the teacher’s actions in case of detection were whether the teachers had children with autism spectrum disorder in the classroom and the education they had received on those issues
Weight cycling in competitive judokas
Creators: name: Brewer, Paula E.
Publisher: name: University of British Columbia

description: It has been suggested that repeated cycles of weight loss, followed by weight gain (termed weight cycling) will lead to metabolic and physiological adaptations which increase food efficiency and thus cause resistance to future weight loss. Athletes who compete in Judo (named judokas), were used as an athletic model of weight cycling. Some judokas cut weight (lose weight) repeatedly, in order to meet specific weight categories for competition, and may therefore represent a weight cycling population. Consequently it is important to determine if suggested metabolic and physiological adaptations associated with weight cycling occur in these athletes. Two groups, weight cyclers (n=9) and matched non-cyclers (n=9),were followed over a period of 10 months (including one competitive season). They followed similar training routines. Weight cyclers dieted (cut weight) in order to compete in a weight class below their usual bodyweight, because they believed that this would give them an advantage over their opponents. Dieting habits were characterized by food restriction an average of 8.1±6.9 (mean±SD) days before their competition. Following the competition, weight was regained to baseline values. There was no significant difference in lean body mass, percentage body fat, height, weight, age, or activity level between the two group sat baseline. Measurements were recorded three times within a one year period. The first pre-season (baseline) value was measured when the judokas were training, but had not yet started to diet for competition. The second test session was during their peak season, at which point the weight cyclers had experienced episodes of weight reduction to meet competitive weight classes. The final test session was conducted during the off-season, at least three months after the Judo season had ended. Measurements included resting energy expenditure (REE), body composition (skinfolds), usual three day food intake (three day food records), and biochemical parameters (fasting insulin, glucose and triiodothyronine). The weight cyclers lost 4.1±1.5 kg, 4.2±2.7 (mean±SD) times per season, whereas the non-cyclers lost little or no weight throughout the study. Weight loss was achieved primarily through food restriction. There was no significant difference in metabolic or physiological parameters between the weight cyclers and the non-cyclers during any of the three test sessions. This study indicated that there were no effects of weight cycling in this athletic population. It is possible that regular physical activity protected against any suggested metabolic adaptations.

description: We construct the integral equations by taking the thermodynamic limit of both the all-loop gauge Bethe ansatz equation and the string Bethe ansatz equation for the highest states in the su(1|1) and su(2) sectors of the N=4 super Yang-Mills theory. Using the Fourier transformation we solve the integral equations iteratively to obtain the anomalous dimensions of the highest states in the weak coupling expansion. In the su(1|1) sector we analytically study the strong coupling limit of the anomalous dimension for the all-loop gauge Bethe ansatz equation by means of the Laplace transformation.

description: We use Bayesian model selection tools to forecast the Planck satellite's ability to distinguish between different models for the reionization history of the Universe, using the large angular scale signal in the cosmic microwave background polarization spectrum. We find that Planck is not expected to be able to distinguish between an instantaneous reionization model and a two-parameter smooth reionization model, except for extreme values of the additional reionization parameter. If it cannot, then it will be unable to distinguish between different two-parameter models either. However, Bayesian model averaging will be needed to obtain unbiased estimates of the optical depth to reionization. We also generalize our results to a hypothetical future cosmic variance limited microwave anisotropy survey, where the outlook is more optimistic.

description: The noncentrosymmetric RAlPn (R = rare earth, Pn = Si, Ge) family, predicted to host nonmagnetic and magnetic Weyl states, provide an excellent platform for investigating the relation between magnetism and Weyl physics. By using high field magnetotransport measurements and first principles calculations, we have unveiled herein both type-I and type-II Weyl states in the nonmagnetic LaAlSi. By a careful comparison between experimental results and theoretical calculations, nontrivial Berry phases associated with the Shubnikov-de Haas oscillations are ascribed to the electron Fermi pockets related to both types of Weyl points located ~ 0.1 eV above and exactly on the Fermi level, respectively. Under high magnetic field, signatures of Zeeman splitting are also observed. These results indicate that, in addition to the importance for exploring intriguing physics of multiple Weyl fermions, LaAlSi as a comparison with magnetic Weyl semimetals in the RAlPn family would also yield valuable insights into the relation between magnetism and Weyl physics.

description: A long-standing goal of materials science is to understand, predict and control the evolution of microstructures in crystalline materials. Most microstructure evolution is controlled by interface motion; hence, the establishment of rigorous interface equations of motion is a universal goal of materials science. We present a new model for the motion of arbitrarily curved interfaces that respects the underlying crystallography of the two phases/domains meeting at the interface and is consistent with microscopic mechanisms of interface motion; i.e., disconnection migration (line defects in the interface with step and dislocation character). We derive the equation of motion for interface migration under the influence of a wide range of driving forces. In Part II of this paper [Salvalaglio, Han and Srolovitz, 2021], we implement the interface model and the equation of motion proposed in this paper in a diffuse interface simulation approach for complex morphology and microstructure evolution.

description: The motion of interfaces is an essential feature of microstructure evolution in crystalline materials. While atomic-scale descriptions provide mechanistic clarity, continuum descriptions are important for understanding microstructural evolution and upon which microscopic features it depends. We develop a microstructure evolution simulation approach that is linked to the underlying microscopic mechanisms of interface migration. We extend the continuum approach describing the disconnection-mediated motion of interfaces introduced in Part I [Han, Srolovitz and Salvalaglio, 2021] to a diffuse interface, phase-field model suitable for large-scale microstructure evolution. A broad range of numerical simulations showcases the capability of the method and the influence of microscopic interface migration mechanisms on microstructure evolution. These include, in particular, the effects of stress and its coupling to interface migration which arises from disconnections, showing how this leads to important differences from classical microstructure evolution represented by mean curvature flow.

Πρόκειται για μια κατευθυνόμενη από τα δεδομένα προσέγγιση, η οποία εστιάζει στη δυνατότητα των ίδιων των κείμενων και των γλωσσικών επιλογών που αναδεικνύουν να διαμορφώσουν τα λήμματα εσωτερικά και να αποτελέσουν δείκτη σημασιολογικής εγγύτητας ή απόκλισης μεταξύ λημμάτων. Επιπλέον, έχει ως στόχο την ανάδειξη της συσταδοποίησης ως μεθόδου λεξικογραφικού τύπου ταξινομήσεων και τον συνδυασμό της με άλλα μεθοδολογικά εργαλεία. Στο πλαίσιο της εργασίας καταρτίστηκε ένα ΣΚ δημοσιογραφικού λόγου και αναλύθηκαν οι σχέσεις μεταξύ των πενήντα συχνότερων ρημάτων με βάση ένα πλαίσιο επισημείωσης με σημασιολογικές και συντακτικές κατηγορίες. Η επεξεργασία των δεδομένων έγινε μέσω της γλώσσας προγραμματισμού R και αναδείχθηκε η λειτουργία του δείκτη tf-idf, η έννοια του βέλτιστου αριθμού συστάδων, η ιεραρχική συσταδοποίηση και η συσταδοποίηση μέσω k-means. Τέλος, τα αποτελέσματα αναλύθηκαν και η έρευνα οδηγήθηκε σε ορισμένα συμπεράσματα
description: The aim of this paper, which is based on the fields of Lexicography and Lexicology, is to detect the semantic distance between verbs and be the first step towards the development of a corpus-based dictionary based on a journalistic corpus. This is a corpus-driven approach, which focuses on the ability of texts and their linguistic preferences to shape dictionary entries internally and to be an indicator of semantic proximity or deviation between the entries. Furthermore, it aims to highlight clustering as a lexicographic classification method and examine its combination with other methodological tools. In this context, a journalistic corpus was created and the relations between the fifty more frequent verbs based on an annotation scheme were analyzed. The processing of the data was done through the programming language R. Terms, such as the tf-idf index, the optimal number of clusters, hierarchical clustering and clustering through k-means are being discussed. Finally, the results were analyzed and some conclusions were drawn

description: A new $γ$-ray source with a significance level of approximately 5$σ$ was reported in the region of SNR G272.2-3.2, analysing the approximately 12.4 years of observation data from the Fermi Large Area Telescope (Fermi-LAT). Its $γ$-ray spatial distribution did not show extended feature, and it had a soft spectrum with the spectral index of 2.56$\pm$0.01 of a power-law model. No significant variability of its light curve (LC) with 10 time bins was identified, and its spatial positions in the X-ray and GeV bands overlapped. We suggest that the new $γ$-ray source is a likely counterpart of SNR G272.2-3.2. Analysing its spectrum, we discussed the likely origins of the $γ$-ray emission.
