description: A study of the practice of dictamen among the schools and chanceries of Late medieval Europe (13th–15th c.) offers a broad range of perspectives in order to map neglected dimensions of late medieval textual cultures. It is well known that Ars dictaminis was a set of rhetorical doctrines, mostly devised for and used in the world of chanceries and for the redaction of letters and charters. But how exactly did the process of translation of a sophisticated rhetoric in an epistolary, mostly political practice, work? This paper focuses on the coalescence and the impact of the rhetoric ‘database’ constituted by the great collections of dictamina traditionally called summae dictaminis. This material served as a matrix to create an immense array of rhetorically and rhythmically similar texts throughout Europe during at least two centuries. This process transcends the disciplinary frontiers between literary and politico-administrative studies. Not only had classical ars dictaminis developed into a sort of semi-formulaic logic, a combinatory technique that was in some ways more akin to poetry than to what we would imagine under the heading of ‘letter writing,’ but the variety of texts impacted by these techniques also cancelled every genetic barrier between ‘literary’ and ‘non-literary’ textual production.

description: Gallium nitride (GaN), a wide band-gap semiconductor, has been broadly used in power electronic devices due to its high electron mobility and high breakdown voltage. Its relatively high thermal conductivity makes GaN a favorable material for such applications, where heat dissipation is a major concern for device efficiency and long-term stability. However, in GaN-based transistors, where the active region can withstand extremely strong electric fields, the field effect on the thermal transport properties has drawn little attention so far. In this work, we apply first-principles methods to investigate phonon properties of wurtzite GaN in the presence of a near-breakdown electric field applied along different crystallographic directions. We find that the electric field changes thermal conductivity considerably via impacting the bond stiffness and ionicity as well as the crystal symmetry, although it has little effect on phonon dispersions. The presence of an out-of-plane electric field increases (decreases) the thermal conductivity parallel (perpendicular) to the electric field, which is attributed to different changes of the Ga-N bond stiffness and ionicity. When an in-plane electric field is applied, the sizable decrease of thermal conductivities along all directions is attributed to the crystal symmetry breaking that enhances the phonon-phonon scattering. Our study provides insights into the effect of extreme external electric fields on phonon transport properties in wide-gap semiconductors.

Genealogies of Czech Literary History
Creators: name: Rychterová, Pavlína
Publisher: name: University of Milan
Year: 2015

description: The article analyses the most important and most influential narratives of the history of Czech medieval literature that were produced from the beginnings of modern historiography and literary history in the 19th century onwards. The question is how the character of individual narratives and their socio-historical contexts influenced the questions, topics and areas of interest in research on the history of medieval literatures in Bohemia. For Czech literature, such analysis is especially important, because it shows that the problems the history of Czech literature has had to fight from its modern beginnings are also the problems of any new approach that literary historiography may pursue in future, from whatever point of departure. The narratives on which the article focuses are built on an amalgamation of the history of society, language and literature, which a) makes it difficult to supersede them and b) makes any detailed research on transmitted texts look less important. Here lies one of the challenges for future research: the relation of language, text and social and political history has to be analysed in detail, because it is only via their conflation that a coherent narrative of the history of Czech literature has been maintained in the past.

Τι συμβαίνει μέχρι τότε; Ποιες ιδέες διατηρούν οι μαθητές για το άπειρο και ποια είναι η σχέση τους με την επίσημη γνώση; Στην παρούσα εργασία εξετάζονται οι διαισθητικές ιδέες των μαθητών των δύο τελευταίων τάξεων του Δημοτικού όσον αφορά τα απειροσύνολα και τη σύγκρισή τους. Πιο συγκεκριμένα, μελετώνται αρχικά οι στρατηγικές που χρησιμοποιούν για να τα συγκρίνουν και σε δεύτερο στάδιο η επίδραση που έχει ο τρόπος που αναπαριστώνται στη χρήση των στρατηγικών αυτών. Τα αποτελέσματα της έρευνας φανερώνουν ότι οι μαθητές γενικεύουν τις στρατηγικές που εφαρμόζονται στη σύγκριση πεπερασμένων συνόλων και στη σύγκριση απειροσυνόλων. Η κατάλληλη αναπαράσταση όμως των απειροσυνόλων μπορεί να ωθήσει προς τη σωστή κατεύθυνση τους μαθητές και να εντοπίσουν έτσι την ‘1-1’ αντιστοιχία μεταξύ των στοιχείων τους, που αποτελεί και την αποδεκτή για σύγκριση απειροσυνόλων στρατηγική
description: The concept of infinity constitutes a corner stone in Mathematics. However, it is only in secondary education that students are introduced formally to it. It is reasonable then to wonder about the prior ideas the students have about infinity as well as to what extend these ideas correspond to the formal knowledge. This research study examines how primary school students approach the issue of comparing infinite sets. More precisely, the focus is on the strategy the students apply to compare such sets as well as the impact of the sets’ representations on the selection of certain strategies. The findings give evidence that the students transfer the strategies for comparing finite sets to compare now infinite ones Th proper use of representations seems that guides students towards the use of the one-to-one correspondence between the elements of the sets, which actually is the mathematically appropriate method for comparing infinite sets

description: The evidence for particle acceleration in supernova shells comes from electrons whose synchrotron emission is observed in radio and X-rays. Recent observations by the HESS instrument reveal that supernova remnants also emit TeV gamma-rays; long awaited experimental evidence that supernova remnants can accelerate cosmic rays up to the ``knee'' energies. Still, uncertainty exists whether these gamma-rays are produced by electrons via inverse Compton scattering or by protons via neutral pion decay. The multi-wavelength spectra of supernova remnants can be fitted with both mechanisms, although a preference is often given to neutral pion decay due to the spectral shape at very high energies. A recent study of the interstellar radiation field indicates that its energy density, especially in the inner Galaxy, is higher than previously thought. In this paper we evaluate the effect of the interstellar radiation field on the inverse Compton emission of electrons accelerated in a supernova remnant located at different distances from the Galactic Centre. We show that contribution of optical and infra-red photons to the inverse Compton emission may exceed the contribution of cosmic microwave background and in some cases broaden the resulted gamma-ray spectrum. Additionally, we show that if a supernova remnant is located close to the Galactic Centre its gamma-ray spectrum will exhibit a ``universal'' cutoff at very high energies due to the Klein-Nishina effect and not due to the cut-off of the electron spectrum. As an example, we apply our calculations to the supernova remnants RX J1713.7-3946 and G0.9+0.1 recently observed by HESS.

description: Automated classification of the anatomical regions of digital intraoral periapical x-rays only through pixel data can provide significant benefits. In this study, 36 neural network models, mainly convolutional, were systematically developed, trained, validated for the above purpose with a relatively limited radiographic dataset, and then evaluated and compared on their performance, training parameters and architecture, in a sufficiently balanced test set. Based on the results, it is concluded that artificial neural networks are suitable for this purpose, with an expected prediction accuracy of 80 – 90%. It is proposed to use deep convolutional architectures that have been recently introduced in the literature, while using extensive data augmentation, image data normalization, and the use of a Global Average Pooling layer to reduce the model size. Model selection in the clinical setting should be based on clinical limitations
From Comparatism to Comparativity: Comparative Reasoning Reconsidered

description: Comparative literature was born with the national paradigm of literary historiography in the early nineteenth century when literary studies, together with other historical and comparative studies, were institutionalized as a particular field of research and higher education. The cognitive pattern generated by this paradigm comprises both national literary studies and comparative literature. They are both instances of comparatism, solidly anchored in a national context as its basic and indispensable point of reference rather than in the border crossing life of literary texts. In contrast, the comparative reasoning of the twenty first century, as exemplified by the emerging interest in world literature studies, attempts to cultivate the comparativity of the literary texts themselves – their potential to engage with several possible contexts of comparison beyond the standard theories and methods of comparatism and without giving an axiomatic priority to one of them. In the traditional aesthetics of imitation, European and non European, the double nature of any text as being organized around both an external centre and a domestic centre is already an integral part of the definition of literature in view, first of all, of their degree of canonicity. Today, more radically, all literary texts, irrespective of canonical position but as part of their status and function as literary texts, are assumed to possess the capacity to be part of several textual and cultural contexts beyond that of their place and time of origin. The paper traces the history of comparative reasoning, leading both to the national paradigm and the nineteenth century inspired comparatism and to the consequences for modern literary studies, opening a broader view of the comparative potentials of texts across time and space.

description: Convection and turbulence in core-collapse supernovae (CCSNe) are inherently three-dimensional in nature. However, 3D simulations of CCSNe are computationally demanding. Thus, it is valuable to modify simulations in spherical symmetry to incorporate 3D effects using some parametric model. In this paper, we report on the formulation and implementation of general relativistic (GR) neutrino-driven turbulent convection in the spherically symmetric core-collapse supernova code \texttt{GR1D}. This is based upon the recently proposed method of Supernova Turbulence in Reduced-dimensionality (\textit{STIR}) in Newtonian simulations from \cite{Couch2020_STIR}. When the parameters of this model are calibrated to 3D simulations, we find that our GR formulation of \textit{STIR} requires larger turbulent eddies to achieve a shock evolution similar to the original \textit{STIR} model. We also find that general relativity may alter the correspondence between progenitor mass and successful vs.~failed explosions.

description: We reconsider the widely held view that the Mannheim--Kazanas (MK) vacuum solution for a static, spherically-symmetric system in conformal gravity (CG) predicts flat rotation curves, such as those observed in galaxies, without the need for dark matter. This prediction assumes that test particles have fixed rest mass and follow timelike geodesics in the MK metric in the vacuum region exterior to a spherically-symmetric representation of the galactic mass distribution. Such geodesics are not conformally invariant, however, which leads to an apparent discrepancy with the analogous calculation performed in the conformally-equivalent Schwarzschild-de-Sitter (SdS) metric, where the latter does not predict flat rotation curves. This difference arises since the mass of particles in CG must instead be generated dynamically through interaction with a scalar field. The energy-momentum of this required scalar field means that, in a general conformal frame from the equivalence class of CG solutions outside a static, spherically-symmetric matter distribution, the spacetime is not given by the MK vacuum solution. A unique frame does exist, however, for which the metric retains the MK form, since the scalar field energy-momentum vanishes despite the field being non-zero and radially dependent. Nonetheless, we show that in both this MK frame and the Einstein frame, in which the scalar field is constant, massive particles follow timelike geodesics of the SdS metric, thereby resolving the apparent frame dependence of physical predictions and unambiguously yielding rotation curves with no flat region. We also comment on how our analysis resolves the long-standing uncertainty regarding gravitational lensing in the MK metric. (Abridged)

description: This contribution is a plea for the substitution of the grand narratives of literary history by small ‘good (hi)stories.’ These ‘good (hi)stories’ must be based on a detailed reconstruction of the literary realities: on the testimony of the work itself, on its transmission, on the description of the social networks in which the works circulated and which they addressed. An integrated view of these ‘good (hi)stories’ can help develop a dynamically changing picture of a possible literary history of the Middle Ages which must be negotiated further in the scholarly discussion. Two examples will demonstrate this model: Otfried’s Evangelienbuch and the paraphrase of the Song of Songs by Williram of Ebersberg.

description: The Talbot effect, epitomized by periodic revivals of a freely evolving periodic field structure, has been observed with waves of diverse physical nature in space and separately in time, whereby diffraction underlies the former and dispersion the latter. To date, a combined spatio-temporal Talbot effect has not been realized in any wave field because diffraction and dispersion are independent physical phenomena, typically unfolding at incommensurable length scales. Here we report the observation of an optical 'space-time' Talbot effect, whereby a spatio-temporal optical lattice structure undergoes periodic revivals after suffering the impact of both diffraction and dispersion. The discovered space-time revivals are governed by a single self-imaging length scale, which encompasses both spatial and temporal degrees of freedom. Key to this effect is the identification of a unique pulsed optical field structure, which we refer to as a V-wave, that is endowed with intrinsically equal diffraction and dispersion lengths in free space, thereby enabling self-imaging to proceed in lockstep in space and time.

description: In this paper, we present a Kane-Mele model in the presence of magnetic field and next nearest neighbors hopping amplitudes for investigations the electronic and optical properties of monolayer Germanene. Specially, we address the dynamical conductivity of the structure as a function of photon frequency and in the presence of magnetic field and spin-orbit coupling at finite temperature. Using linear response theory and Green's function approach, the frequency dependence of optical conductivity has been obtained in the context of Kane-Mele model Hamiltonian. Our results show a finite Drude response at low frequency at non zero value for magnetic field in the presence of spin-orbit coupling. However Drude weight gets remarkable amount in the presence of electron doping. The thermal conductivity and specific heat increase with increasing the temperature at low amounts of temperature due to the increasing of thermal energy of charge carriers and excitation of them to the conduction bands. The results for Seebeck coefficient show the sign of thermopower is negative in the presence of spin-orbit coupling. Also we have studied the temperature dependence of electrical conductivity of Germanene monolayer due to both spin orbit coupling and magnetic field factors in details.

description: The dissipative mechanism at low current density is compared in three different classes of superconductors. This is achieved by measurement of resistance as a function of temperature and magnetic field in clean polycrystalline samples of NbSe2, MgB2 and Bi2Sr2Ca2Cu3O10 superconductors. Thermally activated flux flow behavior is clearly identified in bulk MgB2. While the activation energy at low fields for MgB2 is comparable to Bi2Sr2Ca2Cu3O10, its field dependence follows a parabolic behavior unlike a power law dependence seen in Bi2Sr2Ca2Cu3O10. We analyze our results based on the Kramer's scaling for grain boundary pinning in MgB2and NbSe2.

description: Casual readers and scholars alike celebrate Petrarch’s Rerum vulgarium fragmenta (RVF) as an early masterpiece of vernacular lyric. Yet Petrarch directed most of his professional energies as writer to Latin composition, in the belief that Latin was the language of his most important literary models and of the literary future. This essay studies Petrarch’s life – in particular, episodes revealing his conflicted attitudes toward the sea and especially toward travel by ship – in order to comment on his attitude toward the language of literature: his respect for Latin, his enduring affection for Italian, and his work on the vernacular lyrics at the very end of his life. The essay uses Theodor Adorno’s formulation of late style (Adorno used this concept to discuss the late work of composers, in particular Beethoven) to describe Petrarch’s late work on the RVF in his last years. It argues that Petrarch’s turn to the vernacular in his final years should be read as a kind of linguistic experimentalism – fragmentary and catastrophic, as Adorno would describe it, rather than sweet, unified and harmonic – made possible when Petrarch is no longer using Latin to think about literary posterity.

description: We study how the structure of the interaction graph of a game affects the existence of pure Nash equilibria. In particular, for a fixed interaction graph, we are interested in whether there are pure Nash equilibria arising when random utility tables are assigned to the players. We provide conditions for the structure of the graph under which equilibria are likely to exist and complementary conditions which make the existence of equilibria highly unlikely. Our results have immediate implications for many deterministic graphs and generalize known results for random games on the complete graph. In particular, our results imply that the probability that bounded degree graphs have pure Nash equilibria is exponentially small in the size of the graph and yield a simple algorithm that finds small nonexistence certificates for a large family of graphs. Then we show that in any strongly connected graph of n vertices with expansion $(1+Ω(1))\log_2(n)$ the distribution of the number of equilibria approaches the Poisson distribution with parameter 1, asymptotically as $n \to +\infty$.

Choosing Border Work

Publisher: name: Canadian Journal of Native Education

description: Assuming that research, the creation of knowledge, influences local power and authority and may in fact contribute to changing power relationships between First Nations and non- First Nations peoples and institutions, is it a paradox for a non-Native researcher to enter a social arena— a Native education centre dedicated to Indian control o f Indian education— and to profess to contribute to the struggle for control, through research? In a retrospective on just such a research project, Haig-Brown conceptualizes her place in the struggle for In­dian control as being on a border that demarcates a wider struggle related to land and to a First Nations definition of people's relationship to land. A subsidiary struggle is for recogni­tion of the legitimacy of First Nations' conceptual ordering of research priorities and of First Nations voice in the articulation of research findings. Haig-Brown reviews the detail of research design, entry into the research "field," the nature of an ethnographer's relation­ ships with the people who provide information, and the choosing of strategies for making generalizations and for reporting the experience. Those discussions are tangential border positions for a triangulated focus on questions about the legitimacy and adequacy of eth­nographic research in such a situation.

description: Σκοπός της παρούσας μεταπτυχιακής εργασίας ήταν η διερεύνηση των αναπαραστάσεων των καθηγητών γλωσσών της πρωτοβάθμιας και δευτεροβάθμιας εκπαίδευσης στην Ελλάδα τόσο για την αρχική και τη συνεχιζόμενη κατάρτισή τους σε θέματα διαπολιτισμικότητας, όσο και για τη χρήση της διαπολιτισμικής προσέγγισης κατά τη διάρκεια των διδακτικών τους πρακτικών έχοντας ως στόχο τη βελτιστοποίηση των παιδαγωγικών προσεγγίσεων. Προκειμένου να επιτευχθεί αυτός ο στόχος, διεξήγαμε μια ποιοτική έρευνα χρησιμοποιώντας ένα δείγμα αποτελούμενο από δέκα καθηγήτριες γλωσσών που εργάζονται στην πρωτοβάθμια και δευτεροβάθμια εκπαίδευση στην Ελλάδα, σε μικτές τάξεις. Επιλέξαμε την ημιδομημένη συνέντευξη ως εργαλείο συλλογής δεδομένων, εφόσον το ενδιαφέρον μας επικεντρωνόταν κυρίως στην ερμηνεία των αναπαραστάσεων, των στάσεων, των σκέψεων και των συναισθημάτων των εκπαιδευτικών. Σε ότι αφορά τα αποτελέσματα της έρευνάς μας, διαπιστώσαμε ότι οι περισσότερες καθηγήτριες, παρά την έλλειψη αρχικής και συνεχιζόμενης κατάρτισης, καταβάλλουν σοβαρές προσπάθειες για να ενσωματώσουν τη διαπολιτισμική προσέγγιση στις διδακτικές πρακτικές τους. Ωστόσο, μερικές από αυτές συνεχίζουν να δίνουν μεγαλύτερη βαρύτητα στη διδασκαλία της γλωσσικής δεξιότητας ακολουθώντας πιστά το αναλυτικό πρόγραμμα. Κατά συνέπεια, πρέπει να γίνουν ακόμη πολλά για να προωθηθεί η ανάπτυξη της διαπολιτισμικής δεξιότητας προς όφελος της διδασκαλίας των γλωσσών
description: The aim of the present thesis was to probe the representations of language teachers of primary and secondary education in Greece regarding not only their own initial and continuous training in interculturality but also the use of the intercultural approach during their didactic practices having as a goal the optimization of pedagogical approaches. In order to meet this objective, we conducted a qualitative survey using a sample composed of ten female language teachers working in primary and secondary education in Greece, in mixed classes. We chose the semi-structured interview as a data collection tool, since our interest focused mainly on the interpretation of representations, attitudes, thoughts and feelings of teachers. Regarding the results of our survey, we found that most teachers, despite the lack of initial and continuous training, are making serious efforts to integrate the intercultural approach into their teaching practices. Nevertheless, some of them continue to give more weight to the teaching of linguistic competence by faithfully following the analytical program. Consequently, much remains to be done to promote the development of intercultural competence for the benefit of language teaching

description: Observations of gamma-ray burst afterglows suggest that the correlation length of magnetic field fluctuations downstream of relativistic non-magnetized collisionless shocks grows with distance from the shock to scales much larger than the plasma skin depth. We argue that this indicates that the plasma properties are described by a self-similar solution, and derive constraints on the scaling properties of the solution. For example, we find that the scaling of the characteristic magnetic field amplitude with distance from the shock is B \propto D^{s_B} with -1 \propto x^{2s_B} (for x>>D). We show that the plasma may be approximated as a combination of two self-similar components: a kinetic component of energetic particles and an MHD-like component representing "thermal" particles. We argue that the latter may be considered as infinitely conducting, in which case s_B=0 and the scalings are completely determined (e.g. dn/dE \propto E^{-2} and B \propto D^0). Similar claims apply to non- relativistic shocks such as in supernova remnants, if the upstream magnetic field can be neglected. Self-similarity has important implications for any model of particle acceleration and/or field generation. For example, we show that the diffusion function in the angle μof momentum p in diffusive shock acceleration models must satisfy D_{μμ}(p,D) = D^{-1}D'_{μμ}(p/D), and that a previously suggested model for the generation of large scale magnetic fields through a hierarchical merger of current-filaments should be generalized. A numerical experiment testing our analysis is outlined (Abridged).

description: We investigate the liberation of an atomic electron by a linearly polarized single-cycle near-infrared laser pulse having a peak intensity that ensures tunneling. Based on phase space analysis and energy distribution in the instantaneous potential, we reveal the importance of quantum interference between tunneling and over-the-barrier pathways of escape. Tunneling is blurred both in space and time, and the contribution of tunneling at the mean energy is almost negligible. We suggest and justify improved initial conditions for a classical particle approximation of strong-field ionization, based on the quantum momentum function, and we show how to reconstruct them from the detected momentum of an escaped electron.
Der Philosoph als Nekromant: Gerbert von Aurillac (Silvester II.) und Vergil im europäischen Hochmittelalter
Creators: name: Ricklin, Thomas
Publisher: name: University of Milan
Year: 2015
Subjects: Gerbert of Aurillac; Vergil; image of the philosopher; necromancer; Naples

description: The philosopher as necromancer is a commonplace medieval reality. This paper traces how William of Malmesbury invents the figure of a necromantic philosopher in the person of Gerbert of Aurillac. This new image of the philosopher, which William elaborates using many classical and religious reminiscences, gave personal expression, at the beginning of the 12th century, primarily to fears generated by new knowledge arriving from Arabic sources. As a figure inspiring terror, however, the necromantic philosopher did not exist for long. As the second part of the paper will argue, his disappearance owes nothing to scientific progress or religious enlightenment, but is rather connected with the emergence of a new cycle of legends. Virgil is their protagonist: in the new legends that begin to circulate in the late 12th century, the Latin vates becomes a kind of magician. He uses his magical powers, however, not so much for his own benefit as to help out his adopted hometown of Naples. Thanks to Virgil, or rather thanks to the new Neapolitan stories about him, the formerly evil necromantic philosopher turns into a good necromantic philosopher, whose newly positive image colours the representation of many great philosophers in the following centuries.

description: The purpose of these guidelines (“Test Guidelines”) is to elaborate the principles contained in the General Introduction (document TG/1/3), and its associated TGP documents, into detailed practical guidance for the harmonized examination of distinctness, uniformity and stability (DUS) and, in particular, to identify appropriate characteristics for the examination of DUS and production of harmonized variety descriptions.
'Translatio studii' e 'translatio imperii.' Appunti per un percorso

Publisher: name: University of Milan
Year: 2015
Subjects: Daniel's prophecies; translatio imperii; paganism vs. christianity; Alcuin; Paris caput studiorum; Italian pre-humanism; Arnaldo da Brescia; Brunetto Latini

description: The essay reconsiders in a broader framework the theme of translatio studii already studied by Etienne Gilson. This broader context moves from the ancient biblical model (Daniel’s dream) to the sketch of a progressive understanding of historical events drawn from the theories concerning the succession of earthly kingdoms and their eras, derived from Roman historical thought. In the Early Middle Ages this idea was interpreted in a contradictory and even negative way, since Christian thought tended to reduce the autonomy of human history as governed by its own principles. However, after the experience of the Carolingian Empire the theory of the succession of kingdoms was revived. It was fully developed in France in the following centuries, in order to exalt the French kingdom as taking up the legacy of Greek and Roman civilization. This interpretation had strong nationalistic connotations, which were opposed by the great cultural utopia of the Italian humanism and its ‘dream’ (as Rico called it), and its greatest and most tireless interpreter, Petrarch.

Double exchange model in cubic vanadates

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We investigate the role of the double exchange mechanism for stability of the metallic C-type antiferromagnetic (C-AF) phase, which was observed experimentally in hole doped La$_{1-x}$Sr$_x$VO$_3$. The double exchange model treats localized electrons in xy orbitals as classical S=1/2 spins, which interact by Hund's exchange $J_H$ with yz/zx electrons in partly filled $t_{2g}$ orbitals. Including strong on-site Coulomb repulsion $U$ between $t_{2g}$ electrons, and using slave boson method we demonstrate that C-AF and metallic phase can be stabilized due to the specific features of the hopping in degenerate and partly filled $t_{2g}$ orbitals.

description: Let $M$ be the tensor product of finite-dimensional polynomial evaluation Yangian $Y(gl_N)$-modules. Consider the universal difference operator $D = \sum_{k=0}^N (-1)^k T_k(u) e^{-k\partial_u}$ whose coefficients $T_k(u): M \to M$ are the XXX transfer matrices associated with $M$. We show that the difference equation $Df = 0$ for an $M$-valued function $f$ has a basis of solutions consisting of quasi-exponentials. We prove the same for the universal differential operator $D = \sum_{k=0}^N (-1)^k S_k(u) \partial_u^{N-k}$ whose coefficients $S_k(u) : M \to M$ are the Gaudin transfer matrices associated with the tensor product $M$ of finite-dimensional polynomial evaluation $gl_N[x]$-modules.

description: Η επικοινωνία ανάμεσα στα μέλη της εκάστοτε κοινωνίας επιτυγχάνεται με μια κοινή γλώσσα. Την εξέλιξη των κοινωνιών και κατ’ επέκταση των επιστημών και της τεχνολογίας, ακολουθεί η ανάγκη για τη δημιουργία νέων εννοιών και όρων που θα είναι σε θέση να περιγράψουν τις νέες πραγματικότητες. Η παρούσα διπλωματική μελετά την ανεύρεση και καταγραφή όρων στο πεδίο της κοιλιοκάκης και πιο συγκεκριμένα στο υποπεδίο της χημείας. Το πεδίο της κοιλιοκάκης επιλέχθηκε κατόπιν πρότασης από τη Μονάδα Συντονισμού Ορολογίας του Ευρωπαϊκού Κοινοβουλίου (TermCoord) καθώς υπάρχει ανάγκη εμπλουτισμού της βάσης ορολογικών δεδομένων της ΙΑΤΕ σε αυτό το πεδίο, τόσο στα ελληνικά όσο και στα αγγλικά, ενώ το υποπεδίο επιλέχθηκε για να περιοριστεί και να καταστεί πιο στοχευμένη η αναζήτηση. Η αναζήτηση των όρων έγινε μέσα από ποικίλα κείμενα με λέξεις κλειδιά αποφέροντας θετικά αποτελέσματα και μια βαθύτερη γνώση στο πεδίο της κοιλιοκάκης
description: Communication among the members of a society is achieved with a common language. The evolution of societies and, by extension, science and technology, follows the need to create new concepts and terms in order to achieve communication. In this thesis, the need to find and record terms in the field of celiac disease and more specifically in the subfield of chemistry is thoroughly examined. The field of celiac disease was selected on the basis of a proposal by the Terminology Coordination Unit of the European Parliament (TermCord), as it has been considered essential to enrich the IATE’s term base in this field, both in Greek and in English. The subfield was chosen so as to limit the research and make it more specific. The terms were searched and found after examining various types of texts using key words, yielding, in the end, positive results and a deeper knowledge in the field of celiac disease and the subfield of chemistry
