description: We obtain the phase diagram of the half-filled two-dimensional Hubbard model on a square lattice in the presence of Einstein phonons. We find that the interplay between the instantaneous electron-electron repulsion and electron-phonon interaction leads to new phases. In particular, a d$_{x^2-y^2}$-wave superconducting phase emerges when both anisotropic phonons and repulsive Hubbard interaction are present. For large electron-phonon couplings, charge-density-wave and s-wave superconducting regions also appear in the phase diagram, and the widths of these regions are strongly dependent on the phonon frequency, indicating that retardation effects play an important role. Since at half-filling the Fermi surface is nested, spin-density-wave is recovered when the repulsive interaction dominates. We employ a functional multiscale renormalization-group method that includes both electron-electron and electron-phonon interactions, and take retardation effects fully into account.

description: In the status quo, dementia is yet to be cured. Precise diagnosis prior to the onset of the symptoms can prevent the rapid progression of the emerging cognitive impairment. Recent progress has shown that Electroencephalography (EEG) is the promising and cost-effective test to facilitate the detection of neurocognitive disorders. However, most of the existing works have been using only resting-state EEG. The efficiencies of EEG signals from various cognitive tasks, for dementia classification, have yet to be thoroughly investigated. In this study, we designed four cognitive tasks that engage different cognitive performances: attention, working memory, and executive function. We investigated these tasks by using statistical analysis on both time and frequency domains of EEG signals from three classes of human subjects: Dementia (DEM), Mild Cognitive Impairment (MCI), and Normal Control (NC). We also further evaluated the classification performances of two features extraction methods: Principal Component Analysis (PCA) and Filter Bank Common Spatial Pattern (FBCSP). We found that the working memory related tasks yielded good performances for dementia recognition in both cases using PCA and FBCSP. Moreover, FBCSP with features combination from four tasks revealed the best sensitivity of 0.87 and the specificity of 0.80. To our best knowledge, this is the first work that concurrently investigated several cognitive tasks for dementia recognition using both statistical analysis and classification scores. Our results yielded essential information to design and aid in conducting further experimental tasks to early diagnose dementia patients.

Learner and Task Considerations in Designing Instruction for Native Adult Learners
Creators: name: Wiesenberg, Faye P.
Publisher: name: Canadian Journal of Native Education
Year: 2021

description: The study contributes to an exploration of directions in which instruction might be in­dividualized, taking into account modality strength and preference in learning. Rather than following the suggestion in the literature that Native people are predominantly "visual" in learning style in comparison with non-Natives, in this study, which involved 111 non-Na- tive adult learners and 18 Native adult learners, all participants were assessed for relative preference for visual and verbal learning style. Knowledge and comprehension test scores were compared for the groups, relative to their use of instructional material that was dif­ferentiated by the inclusion or absence of analogical visual illustration. Comparisons be­ tween performance outcome measures on the one hand and mental imagery and verbal reasoning subtest scores on the other seemed to indicate different general patterns between Natives and non-Natives. A formally untested but evident conclusion, however, is that in­ dividual differences were as important as Native/non-Native differences. The evident com­ plex interaction of learning style modality preference, instructional material, learning task, and individual and cultural background suggests that in the creation of learning materials, the interaction of instructional variables, not the variables in isolation, should be the focus.

description: Recent experiments on strongly-interacting bosons in optical lattices have revealed the co-existence of spatially-separated Mott-insulating and number-fluctuating phases. The description of this inhomogeneous situation is the topic of this Letter. We establish that the number-fluctuating phase forms a superfluid trapped between the Mott-insulating regions and derive the associated collective mode structure. We discuss the interlayer's crossover between two- and three-dimensional behavior as a function of the lattice parameters and estimate the critical temperatures for the transition of the superfluid phase to a normal phase.

description: This paper illustrates an application of machine learning (ML) within a complex system that performs grade estimation. In surface mining, assay measurements taken from production drilling often provide useful information that allows initially inaccurate surfaces created using sparse exploration data to be revised and subsequently improved. Recently, a Bayesian warping technique has been proposed to reshape modeled surfaces using geochemical and spatial constraints imposed by newly acquired blasthole data. This paper focuses on incorporating machine learning into this warping framework to make the likelihood computation generalizable. The technique works by adjusting the position of vertices on the surface to maximize the integrity of modeled geological boundaries with respect to sparse geochemical observations. Its foundation is laid by a Bayesian derivation in which the geological domain likelihood given the chemistry, p(g|c), plays a similar role to p(y(c)|g). This observation allows a manually calibrated process centered around the latter to be automated since ML techniques may be used to estimate the former in a data-driven way. Machine learning performance is evaluated for gradient boosting, neural network, random forest and other classifiers in a binary and multi-class context using precision and recall rates. Once ML likelihood estimators are integrated in the surface warping framework, surface shaping performance is evaluated using unseen data by examining the categorical distribution of test samples located above and below the warped surface. Large-scale validation experiments are performed to assess the overall efficacy of ML assisted surface warping as a fully integrated component within an ore grade estimation system where the posterior mean is obtained via Gaussian Process inference with a Matern 3/2 kernel.

description: We examine the tripartite entanglement properties of an optical system using interlinked $χ^{(2)}$ interactions, recently studied experimentally in terms of its phase-matching properties by Bondani et al [M. Bondani, A. Allevi, E. Gevinti, A. Agliati, and A. Andreoni, arXiv:quant-ph/0604002.]. We show that the system does produce output modes which are genuinely tripartite entangled and that detection of this entanglement depends crucially on the correlation functions which are measured, with a three-mode Einstein-Podolsky-Rosen inequality being the most sensitive.

description: We report on the analysis of a deep Chandra observation of the high-magnetic field pulsar (PSR) J1119-6127 and its compact pulsar wind nebula (PWN) taken in October 2019, three years after the source went into outburst. The 0.5-7 keV post-outburst (2019) spectrum of the pulsar is best described by a two-component blackbody plus powerlaw model with a temperature of 0.2\pm0.1 keV, photon index of 1.8\pm0.4 and X-ray luminosity of ~1.9e33 erg s^{-1}, consistent with its pre-burst quiescent phase. We find that the pulsar has gone back to quiescence. The compact nebula shows a jet-like morphology elongated in the north-south direction, similar to the pre-burst phase. The post-outburst PWN spectrum is best fit by an absorbed powerlaw with a photon index of 2.3\pm0.5 and flux of ~3.2e-14 erg cm^{-2} s^{-1} (0.5-7 keV). The PWN spectrum shows evidence of spectral softening in the post-outburst phase, with the pre-burst photon index of 1.2\pm0.4 changing to 2.3\pm0.5, and pre-burst luminosity of ~1.5e32 erg s^{-1} changing to 2.7e32 erg s^{-1} in the 0.5-7 keV band, suggesting magnetar outbursts can impact PWNe. The observed timescale for returning to quiescence, of just a few years, implies a rather fast cooling process and favors a scenario where J1119 is temporarily powered by magnetic energy following the magnetar outburst, in addition to its spin-down energy.

description: Deep learning has demonstrated its strengths in numerous binary analysis tasks, including function boundary detection, binary code search, function prototype inference, value set analysis, etc. When applying deep learning to binary analysis tasks, we need to decide what input should be fed into the neural network model. More specifically, we need to answer how to represent an instruction in a fixed-length vector. The idea of automatically learning instruction representations is intriguing, however the existing schemes fail to capture the unique characteristics of disassembly. These schemes ignore the complex intra-instruction structures and mainly rely on control flow in which the contextual information is noisy and can be influenced by compiler optimizations. In this paper, we propose to pre-train an assembly language model called PalmTree for generating general-purpose instruction embeddings by conducting self-supervised training on large-scale unlabeled binary corpora. PalmTree utilizes three pre-training tasks to capture various characteristics of assembly language. These training tasks overcome the problems in existing schemes, thus can help to generate high-quality representations. We conduct both intrinsic and extrinsic evaluations, and compare PalmTree with other instruction embedding schemes. PalmTree has the best performance for intrinsic metrics, and outperforms the other instruction embedding schemes for all downstream tasks.

description: Η ορθολογική συνταγογράφηση είναι μια διαδικασία απαραίτητη για κάθε ιατρό, προκειμένου να διασφαλιστεί το καλύτερο δυνατό όφελος για τον ασθενή του. Στην κλινική πράξη, οι ιατροί καλούνται να διαχειριστούν ασθενείς με συννοσηρότητες, ασθενείς σε πολυφαρμακία και ασθενείς των οποίων τα συμπτώματα είναι δύσκολο να διαφοροδιαγνωσθεί αν προκλήθηκαν λόγω της νόσου ή λόγω ανεπιθύμητης ενέργειας κάποιου φαρμάκου. Στο πλαίσιο αυτό, πολλές είναι οι πληροφορίες που δέχονται οι ιατροί σε σχέση με την έναρξη χορήγησης ενός φαρμάκου, όμως λίγα είναι γνωστά σχετικά με τη διακοπή του. Στην παρούσα διπλωματική εργασία, εξετάζεται η απο-συνταγογράφηση (“deprescribing”) ψυχοτρόπων φαρμάκων, δηλαδή η σταδιακή μείωση ή/και διακοπή ενός πιθανόν ακατάλληλου φαρμάκου, με στόχο τη βελτίωση των αποτελεσμάτων και τη διόρθωση της πολυφαρμακίας. Εξετάστηκαν τρεις κατηγορίες ψυχοτρόπων φαρμάκων, τα αντιψυχωτικά, τα αντικαταθλιπτικά, καθώς και οι βενζοδιαζεπίνες και τα παράγωγά τους (“Z-drugs”)
description: The process of rational prescribing is a necessary skill for the physician, in order to ensure the best outcome for his patients. In every day practice, physicians have to manage patients with comorbidities, patients in polypharmacy and patients whose symptoms are difficult to distinguish whether they are caused due to their illness or due to adverse effects of a medication. Furthermore, physicians receive a lot of information on how to start a medication, however, very few are known about stopping it. The purpose of this master’s thesis is to look into “deprescribing” of psychotropic drugs, meaning intentionally stopping an inappropriate drug or reducing its dose, in order to minimize the harmful effects of polypharmacy and improve the outcomes for patients. Three classes of psychotropic drugs are examined here: antipsychotics, antidepressants, benzodiazepines and Z-drugs

Σκοπός της έρευνας είναι να διαφανεί κατά πόσο τα άχυρα των Ελληνικών ποικιλιών χρησιμοποιούμενα ως υπόστρωμα τροφοδοσίας στις μονάδες βιοαερίου θα μπορούσαν να αντικαταστήσουν δυνητικά το ενσίρωμα καλαμποκιού ως προς την παραγωγή τους σε μεθάνιο. Παράλληλα, διερευνήθηκε το δυναμικό παραγωγής σε μεθάνιο έξι συχνά χρησιμοποιούμενων ως υποστρώματα παραπροϊόντων βιομηχανιών τροφίμων σε μονάδες βιοαερίου. Το πείραμα πραγματοποιήθηκε σε 28 αντιδραστήρες διαλείποντος έργου, οι οποίοι λειτουργούσαν στη μεσόφιλη ζώνη στους 37 oC. Όσον αφορά τα γεωργικά υποστρώματα, την υψηλότερη απόδοση μεθανίου παρουσίασε η ποικιλία Γέκορα με 341,33 LCH4kg−1 πτητικών στερεών, με την Λήμνο να ακολουθεί με παραγωγή 270,62 LCH4 kg−1 πτητικών στερεών και την Δίο με 257,72 270,62 LCH4 kg−1 πτητικών στερεών, χωρίς να υπάρχει στατιστικώς σημαντική διαφορά μεταξύ των υποστρωμάτων. Στα μη γεωργικά υποστρώματα οι υψηλότερες αποδόσεις μεθανίου ανήλθαν σε 437,71 LCH4kg−1 πτητικών στερεών (rendering) και 413,59 LCH4kg−1 πτητικών στερεών (ραφιναρία).
description: In the present study, straws of Greek varieties of soft wheat, such as Gekora, Dio and durum wheat Lemnos, were investigated for their yield in methane production. The purpose of the research is to determine whether the straws of the Greek varieties used as feed substrate in biogas units could potentially replace the corn silage in terms of methane production. At the same time, the production potential of methane and six, often used as substrates, by-products of food industries in biogas units were investigated. The experiment was carried out on 28 batch reactors, operating in the mesophilic zone at 37 oC. Concerning agricultural substrates, the highest yield of methane was reported by the Gekora variety with 341.33 LCH4kg-1 volatile solids, followed by Limnos with 270.62 LCH4 kg-1 volatile solids and Zeus with 257.72 270.62 LCH4 kg-1 volatile solids, without statistically significant difference between substrates. In non-agricultural substrates, the highest yields of methane were 437.71 LCH4kg-1 volatile solids (rendering) and 413.59 LCH4kg-1 volatile solids (refineries).

description: Emotional expressions are the behaviors that communicate our emotional state or attitude to others. They are expressed through verbal and non-verbal communication. Complex human behavior can be understood by studying physical features from multiple modalities; mainly facial, vocal and physical gestures. Recently, spontaneous multi-modal emotion recognition has been extensively studied for human behavior analysis. In this paper, we propose a new deep learning-based approach for audio-visual emotion recognition. Our approach leverages recent advances in deep learning like knowledge distillation and high-performing deep architectures. The deep feature representations of the audio and visual modalities are fused based on a model-level fusion strategy. A recurrent neural network is then used to capture the temporal dynamics. Our proposed approach substantially outperforms state-of-the-art approaches in predicting valence on the RECOLA dataset. Moreover, our proposed visual facial expression feature extraction network outperforms state-of-the-art results on the AffectNet and Google Facial Expression Comparison datasets.

description: Quantum resonances in the kicked rotor are characterized by a dramatically increased energy absorption rate, in stark contrast to the momentum localization generally observed. These resonances occur when the scaled Planck's constant hbar=(r/s)*4pi, for any integers r and s. However only the hbar=r*2pi resonances are easily observable. We have observed high-order quantum resonances (s>2) utilizing a sample of low temperature, non-condensed atoms and a pulsed optical standing wave. Resonances are observed for hbar=(r/16)*4pi r=2-6. Quantum numerical simulations suggest that our observation of high-order resonances indicates a larger coherence length than expected from an initially thermal atomic sample.

description: Using Monte-Carlo computer simulations, we study the impact of matter fields on the geometry of a typical quantum universe in the CDT model of lattice quantum gravity. The quantum universe has the size of a few Planck lengths and the spatial topology of a three-torus. The matter fields are multi-component scalar fields taking values in a torus with circumference $δ$ in each spatial direction, which acts as a new parameter in the CDT model. Changing $δ$, we observe a phase transition caused by the scalar field. This discovery may have important consequences for quantum universes with non-trivial topology, since the phase transition can change the topology to a simply connected one.

Mutation testing is generally used by software practitioners to assess the robustness of a given test-suite. However, we leverage this technique to systematically evaluate static analysis tools and uncover and document soundness issues. $μ$SE's analysis has found 25 previously undocumented flaws in static data leak detection tools for Android. $μ$SE offers four mutation schemes, namely Reachability, Complex-reachability, TaintSink, and ScopeSink, which determine the locations of seeded mutants. Furthermore, the user can extend $μ$SE by customizing the API calls targeted by the mutation analysis. $μ$SE is also practical, as it makes use of filtering techniques based on compilation and execution criteria that reduces the number of ineffective mutations.

description: Neologism is the new lexical unit that is introduced into a language dictionary via the complicated process of neology and originates from the compounding of some older linguistic elements or is a loan from a foreign language. The aforementioned phenomenon constitutes an aspect of language change and, due to the fact that its results are detected in the vocabulary part of a language, the speakers can observe them during their short period of existence. The aim of the current work is to trace neologisms in particular texts of Greek Enlighteners (archaists, advocates of demotic and modest representatives) and refer to their attitude towards this phenomenon. In more details, original texts, translated ones and greek papers have been used. Our research has been based on the dictionary of Stephanos Koumanoudis, the only Greek work that includes neologisms, whereas some older and contemporary dictionaries have also assisted the whole process. Finally, a wide range of neologisms has been recorded and then classified by their way of formation and their loan type

description: Neural-network quantum states (NQS) have become a powerful tool in many-body physics. Of the numerous possible architectures in which neural-networks can encode amplitudes of quantum states the simplicity of the Restricted Boltzmann Machine (RBM) has proven especially useful for both numerical and analytical studies. In particular devising exact NQS representations for important classes of states, like Jastrow and stabilizer states, has provided useful clues into the strengths and limitations of the RBM based NQS. However, current constructions for a system of $N$ spins generate NQS with $M \sim O(N^2)$ hidden units that are very sparsely connected. This makes them rather atypical NQS compared to those commonly generated by numerical optimisation. Here we focus on compact NQS, denoting NQS with a hidden unit density $α= M/N \leq 1$ but with system-extensive hidden-visible unit connectivity. By unifying Jastrow and stabilizer states we introduce a new exact representation that requires at most $M=N-1$ hidden units, illustrating how highly expressive $α\leq 1$ can be. Owing to their structural similarity to numerical NQS solutions our result provides useful insights and could pave the way for more families of quantum states to be represented exactly by compact NQS.

Η συλλογή του διαλεκτικού υλικού βασίστηκε στην αποδελτίωση των φρασεολογισμών από τα λογοτεχνικά έργα των συγγραφέων Τ. Κώτσια και Σ. Δημητρίου, οι οποίοι γράφουν χρησιμοποιώντας συστηματικά τη διάλεκτο. Στο υλικό προστέθηκαν και άλλες φρασεολογικές μονάδες των τοπικών ιδιωμάτων, οι οποίες αντλήθηκαν από εργασίες που αφορούν την περιοχή της Ηπείρου. Στη συνέχεια έγινε μια σύγκριση του συγκεντρωμένου υλικού με το αντίστοιχο φρασεολογικό υλικό που είναι διαθέσιμο για την αλβανική γλώσσα. Η μελέτη ανέδειξε μια σειρά από φρασεολογικά ισοδύναμα ανάμεσα στις δύο γλωσσικές ποικιλίες, τα οποία είναι τα αποτελέσματα των γλωσσικών επαφών μεταξύ των ελληνόφωνων και των αλβανόφωνων πληθυσμών της συγκεκριμένης γεωγραφικής, αλλά και γλωσσικής περιοχής (linguistic area). Επίσης, εντοπίζονται ιδιαίτεροι φρασεολογισμοί της διαλέκτου, γίνεται αναφορά στις παροιμίες της, συζητούνται θέματα που αφορούν την πολιτισμική διάσταση των διαλεκτικών φρασεολογισμών και γίνονται κάποιες παρατηρήσεις σχετικά με τη γεωγραφική τους εξάπλωση
description: The aim of this thesis is to raise questions concerning dialectal phraseology, which is examined within the scope of language contact and Balkan linguistics. In the light of contact linguistics, an attempt was made to examine the phraseological material of the Greek idioms of South Albania and of the mountain region of Thesprotia. The collection of the phraseological material was based on indexing phraseological units from the literary work of T. Kotsias and S. Dimitriou, who systematically use the dialectal variation in their writings. More phraseological units of the local idioms were added, as they derived from work concerning the region of Εpirus. A comparison of the gathered material with the available, corresponding phraseological units coming from the Albanian language was made afterwards. Our study highlighted a series of phraseological equivalents between the two linguistic varieties, which are the result of the language contact between Greek speaking and Albanian speaking populations of this specific geographic, as well as linguistic area. Moreover, characteristic phraseological units and proverbs of the dialect are identified, issues such as the cultural dimension of dialectal phraseology are discussed, and there are some remarks following, concerning the geographical distribution of the units

description: Adversarial input detection has emerged as a prominent technique to harden Deep Neural Networks(DNNs) against adversarial attacks. Most prior works use neural network-based detectors or complex statistical analysis for adversarial detection. These approaches are computationally intensive and vulnerable to adversarial attacks. To this end, we propose DetectX - a hardware friendly adversarial detection mechanism using hardware signatures like Sum of column Currents (SoI) in memristive crossbars (XBar). We show that adversarial inputs have higher SoI compared to clean inputs. However, the difference is too small for reliable adversarial detection. Hence, we propose a dual-phase training methodology: Phase1 training is geared towards increasing the separation between clean and adversarial SoIs; Phase2 training improves the overall robustness against different strengths of adversarial attacks. For hardware-based adversarial detection, we implement the DetectX module using 32nm CMOS circuits and integrate it with a Neurosim-like analog crossbar architecture. We perform hardware evaluation of the Neurosim+DetectX system on the Neurosim platform using datasets-CIFAR10(VGG8), CIFAR100(VGG16) and TinyImagenet(ResNet18). Our experiments show that DetectX is 10x-25x more energy efficient and immune to dynamic adversarial attacks compared to previous state-of-the-art works. Moreover, we achieve high detection performance (ROC-AUC > 0.95) for strong white-box and black-box attacks. The code has been released at https://github.com/Intelligent-Computing-Lab-Yale/DetectX

description: The aim of the present thesis was the study of plastic surgeries. We first analyzed the types of plastic surgeries and the responsibility of the plastic surgeon who carries them out in the context of medical negligence and analyzed the case law examples. Then, we looked at the psychiatric contribution that is needed to carry them out, before and after, and we studied the categories of candidates who wish to do so. We also analyzed the confrontation of plastic surgeries by Christianity, both Orthodox and Catholic, and by Islam, describing the similarities and differences between these religions

description: We report on measurements of the anisotropic dynamical polarizability of Dy near the 626-nm intercombination line, employing modulation spectroscopy in a one-dimensional optical lattice. To eliminate large systematic uncertainties resulting from the limited knowledge of the spatial intensity distribution, we use K as a reference species with accurately known polarizability. This method can be applied independently of the sign of the polarizability, i.e., for both attractive and repulsive optical fields on both sides of a resonance. By variation of the laser polarization we extract the scalar and the tensorial part. To characterize the strength of the transition, we also derive the natural linewidth. We find our result to be in excellent agreement with literature values, which provide a sensitive benchmark for the accuracy of our method. In addition we demonstrate optical dipole trapping on the intercombination line, confirming the expected long lifetimes and low heating rates. This provides an additional tool to tailor optical potentials for Dy atoms and for the species-specific manipulation of atoms in the Dy-K mixture.

description: GeV electron bunches accelerated on a centimeter scale device exemplify the extraordinary advances of laser-plasma acceleration. The combination of high charges from optimized injection schemes and intrinsic femtosecond short bunch duration yields kiloampere peak currents. Further enhancing the current while reducing the energy spread will pave the way for future application, e.g. the driver for compact secondary radiation sources such as high-field THz, high-brightness x-ray or gamma-ray sources. One essential key for beam transport to a specific application is an electron bunch with high quality beam parameters such as low energy spread as well as small divergence and spot size. The inherent micrometer size at the plasma exit is typically sufficient for an efficient coupling into a conventional beamline. However, energy spread and beam divergence require optimization before the beam can be transported efficiently. Induced by the high peak current, the beam loading regime can be used in order to achieve optimized beam parameters for beam transport. In this thesis, the impact of beam loading on the transverse electron dynamic is systematically studied by investigating betatron radiation and electron beam divergence. For this reason, the bubble regime with self-truncated ionization injection (STII) is applied to set up a nanocoulomb-class laser wakefield accelerator. The accelerator is driven by 150TW laser pulses from the DRACO high power laser system. A supersonic gas jet provides a 3mm long acceleration medium with electron densities from 3 × 1018 cm−3 to 5 × 1018 cm−3. The STII scheme together with the employed setup yields highly reproducible injections with bunch charges of up to 0.5 nC. The recorded betatron radius at the accelerator exit is about one micron and reveals that the beam size stays at the same value. The optimal beam loading, which is observed at around 250 pC to 300 pC, leads to the minimum energy spread of ~40MeV and a 20% smaller divergence. It is demonstrated that an incomplete betatron phase mixing due to the small energy spread can explain the experimentally observed minimum beam divergence.

description: Forty-eight parents from three First Nations communities in Ontario were interviewed about the value of play and the place of play in early childhood programs. Parents valued play as an appropriate activity for young children and as the way of learning in early childhood. In addition, parents approved of play-oriented programs in daycare centers. Parents made a number of valuable suggestions about child care in general and openly ex­ pressed some of their concerns. Issues important to parents were raised such as the amount of parent involvement in centers, daycare as an opportunity for cultural transmission, and daycare staff training.

description: Σκοπός της διατριβής είναι η φιλολογική και θεολογική προσέγγιση του έπους Περί της του εκτός ανθρώπου ευτελείας του Γρηγορίου Ναζιανζηνού. Παρουσιάσαμε αρχικά το ιδεολογικό, κοινωνικό, πολιτικό, θεολογικό, πολιτιστικό πλαίσιο στο πλαίσιο στο οποίο έζησε και έγραψε ο Γρηγόριος και από τα βιογραφικά του στοιχεία δώσαμε έμφαση σε γεγονότα που επηρέασαν τις σκέψεις και τα συναισθήματά του. Ακόμη αναφερθήκαμε στις θεολογικές του αντιλήψεις και διδασκαλία του για το χρόνο, την εν Χριστώ ζωή, τη φυγή, τον κόσμο, για την πληρέστερη κατανόηση του προς διερεύνηση έπους. Στη συνέχεια μετά το κείμενο παραθέσαμε την απόδοσή του στη νεοελληνική γλώσσα, τη φιλολογική ανάλυσή του από άποψη γλωσσική, υφολογική, αισθητική (με έμφαση στα ρητορικά σχήματα), πραγματολογική και το σχολιασμό των θεολογικών αναφορών στο κείμενο, καθώς και συνοπτικό διάγραμμα της δομής του. Επιπλέον ασχοληθήκαμε με τη σύγκριση του Περί της του εκτός ανθρώπου ευτελείας με τα ηθικά έπη της ίδιας ομάδας (ΙΑ-ΚΔ) και ολοκληρώσαμε την εργασία με δύο παραρτήματα, το πρώτο με το λεξιλόγιο του έπους και το δεύτερο με τα κείμενα της ομάδας (ΙΑ-ΚΔ)
description: The aim of this dissertation is to detect the literary and theological aspects of the Gregory Nazianzen epic On the starkness of the non outer human condition. Having initially explored the ideological, social, political, theological and cultural background in which Gregory lived becoming an author we then proceeded in the stressing of facts and sentiments of his that we regarded as most influential to his work. Following that, we took notice and further referred to his theological ideals and teachings about time, Life in Christ, escapism and the mass in order to proceed in a deeper understanding of the pertaining epic. Next to that, we provided a version of the text in contemporary spoken Greek, an analysis in terms of its literary, linguistic, artistic form, aesthetic (with emphasis on rhetorical patterns) and pragmatic elements with critical remarks on its theological references, as well as a concise table of the dissertation’s structure. Finally, we provided a comparative assessment between On the starkness of the non outer human condition and the ethical epics of this same group (IA – KD) and concluded our dissertation with the addition of two annexes: one containing the epic’s vocabulary and another containing the texts of the group (IA – ΚD)

description: We demonstrate semiconductor superlattices or nanocavities as narrow band acoustic transducers in the sub-terahertz range. Using picosecond ultrasonics experiments in the transmission geometry with pump and probe incident on opposite sides of the thick substrate, phonon generation and detection processes are fully decoupled. Generating with the semiconductor device and probing on the metal, we show that both superlattices and nanocavities generate spectrally narrow wavepackets of coherent phonons with frequencies in the vicinity of the zone center and time durations in the nanosecond range, qualitatively different from picosecond broadband pulses usually involved in picosecond acoustics with metal generators. Generating in the metal and probing on the nanoacoustic device, we furthermore evidence that both nanostructured semiconductor devices may be used as very sensitive and spectrally selective detectors.

description: Associated to a discrete group $G$, one has the topological category of finite dimensional (unitary) $G$-representations and (unitary) isomorphisms. Block sums provide this category with a permutative structure, and the associated $K$-theory spectrum is Carlsson's deformation $K$-theory of G. The goal of this paper is to examine the behavior of this functor on free products. Our main theorem shows the square of spectra associated to $G*H$ (considered as an amalgamated product over the trivial group) is homotopy cartesian. The proof uses a general result regarding group completions of homotopy commutative topological monoids, which may be of some independent interest.
