description: Οι περισσότεροι μαθητές στην προσπάθειά τους να κατακτήσουν και να μάθουν την ελληνική γλώσσα κάνουν λάθη. Το φαινόμενο αυτό παρατηρείται πιο έντονα σε μαθητές που προέρχονται από διαφορετικό πολιτισμικό περιβάλλον. Οι μαθητές αυτοί, ως αλλόγλωσσοι, πραγματοποιούν λάθη τα οποία αποτελούν αναπόφευκτο αποτέλεσμα της όλης διαδικασίας της εκμάθησης της γλώσσας. Ως γλωσσικό λάθος θα μπορούσε να οριστεί κάθε απόκλιση από τη γλωσσική νόρμα, την οποία μια κοινότητα θέτει ως πρότυπο. Τα λάθη αυτά πιθανόν να οφείλονται α) στην παρεμβολή της πρώτης-μητρικής γλώσσας των μαθητών, β) στην υπεργενίκευση των κανόνων της γλώσσας- στόχου, γ)στις μαθησιακές στρατηγικές που χρησιμοποιεί ο μαθητής π.χ. την επανάληψη και δ) στις επικοινωνιακές στρατηγικές. Από την εμπειρική διερεύνηση που πραγματοποιήθηκε σε 4 διαφορετικά δημοτικά σχολεία της Ελλάδας, προκύπτει το συμπέρασμα ότι η πλειονότητα των λαθών εντοπίζεται κυρίως στα φωνολογικά και γραφηματικά λάθη, δηλαδή λάθη στην ορθογραφία, τον τονισμό , την παράλειψη ή την προσθήκη φωνημάτων κ. ά. Διαδοχικά ακολουθούν τα μορφοσυντακτικά λάθη, τα συντακτικά, τα σημασιολογικά και τέλος τα μορφολογικά λάθη. Η συντριπτική πλειοψηφία των γραπτών της διερεύνησής μας προέρχεται από μαθητές αλβανικής καταγωγής και στη συνέχεια ακολουθούν ρωσικής, γεωργιανής, βουλγαρικής και ουκρανικής καταγωγής αντίστοιχα.
description: Most students attempting to acquire and learn the Greek language make mistakes. This phenomenon is more vivid in students who come from a culturally different environment. These students, as speakers of other languages, do errors which constitute an unavoidable outcome of the whole process of language acquisition. A language error could be defined as every deviation from the language norm, which a community sets as a model. These errors may take place due to a) the intervention of the first- mother tongue of the students, b) the overgeneralization of the targeted language, c) the learning strategies the student uses for eg. Revision, d) the communicative strategies. Based on the empirical evidence of the investigation that took place in 4 different elementary schools of Greece, it is concluded that the majority of the errors concerns phonological and grapheme errors, meaning errors in spelling, intonation, the omission or addition of phonemes etc. Consecutively, there are morphosyntactic errors, syntactic errors, semantic errors and finally morphological errors. The overwhelming majority of the writings of our investigation comes from students of Albanian origin and then of Russian, Georgian, Bulgarian and Ukrainian origin respectively.

description: The Sherrington--Kirkpatrick model of spin glasses, the Hopfield model of neural networks and the Ising spin glass are all models of binary data belonging to the one-parameter exponential family with quadratic sufficient statistic. Under bare minimal conditions, we establish the $\sqrt{N}$-consistency of the maximum pseudolikelihood estimate of the natural parameter in this family, even at critical temperatures. Since very little is known about the low and critical temperature regimes of these extremely difficult models, the proof requires several new ideas. The author's version of Stein's method is a particularly useful tool. We aim to introduce these techniques into the realm of mathematical statistics through an example and present some open questions.

description: Events where the two leading jets are separated by a pseudorapidity interval devoid of particle activity, known as jet-gap-jet events, are studied in proton-proton collisions at $\sqrt{s} =$ 13 TeV. The signature is expected from hard color-singlet exchange. Each of the highest transverse momentum ($p_\mathrm{T}$) jets must have $p_\mathrm{T}^\text{jet}$ $\gt$ 40 GeV and pseudorapidity 1.4 $\lt$ $|η^\text{jet}|$ $\lt$ 4.7, with $η^\text{jet1} η^\text{jet2}$ $\lt$ 0, where $\text{jet1}$ and $\text{jet2}$ are the leading and subleading jets in $p_\mathrm{T}$, respectively. The analysis is based on data collected by the CMS and TOTEM experiments during a low luminosity, high-$β^*$ run at the CERN LHC in 2015, with an integrated luminosity of 0.66 pb$^{-1}$. Events with a low number of charged particles with $p_\mathrm{T}$ $\gt$ 0.2 GeV in the interval $|η|$ $\lt$ 1 between the jets are observed in excess of calculations that assume only color-exchange. The fraction of events produced via color-singlet exchange, $f_\text{CSE}$, is measured as a function of $p_\mathrm{T}^\text{jet2}$, the pseudorapidity difference between the two leading jets, and the azimuthal angular separation between the two leading jets. The fraction $f_\text{CSE}$ has values of 0.4-1.0%. The results are compared with previous measurements and with predictions from perturbative quantum chromodynamics. In addition, the first study of jet-gap-jet events detected in association with an intact proton using a subsample of events with an integrated luminosity of 0.40 pb$^{-1}$ is presented. The intact protons are detected with the Roman pot detectors of the TOTEM experiment. The $f_\text{CSE}$ in this sample is 2.91 $\pm$ 0.70 (stat) $^{+1.08}_{-1.01}$ (syst) times larger than that for inclusive dijet production in dijets with similar kinematics.

description: We consider a generic optomechanical system, consisting of a driven optical cavity and a movable mirror attached to a cantilever. Systems of this kind (and analogues) have been realized in many recent experiments. It is well known that those systems can exhibit an instability towards a regime where the cantilever settles into self-sustained oscillations. In this paper, we briefly review the classical theory of the optomechanical instability, and then discuss the features arising in the quantum regime. We solve numerically a full quantum master equation for the coupled system, and use it to analyze the photon number, the cantilever's mechanical energy, the phonon probability distribution and the mechanical Wigner density, as a function of experimentally accessible control parameters. We observe and discuss the quantum-to-classical transition as a function of a suitable dimensionless quantum parameter.

A physical model for indirect noise in non-isentropic nozzles: Transfer functions and stability

description: We propose a mathematical model from physical principles to predict the sound generated in nozzles with dissipation. The focus is on the sound generated from the acceleration of temperature inhomogeneities (also known as entropy waves), which is referred to as indirect noise. First, we model the dissipation caused by flow recirculation and wall friction with a friction factor, which enables us to derive quasi-one-dimensional equations from conservation laws. The model is valid for both compact nozzles and nozzles with a spatial extent. Second, the predictions from the proposed model are compared against the experimental data available in the literature. Third, we compute the nozzle transfer functions for a range of Helmholtz numbers and friction factors. It is found that the friction and the Helmholtz number have a significant effect on the gain/phase of the reflected and transmitted waves. The analysis is performed from subsonic to supersonic regimes (with and without shock waves). The acoustic transfer functions vary significantly because of non-isentropic effects and the Helmholtz number, in particular, in the subsonic-choked regime. Finally, we calculate the effect that the friction of a nozzle guide vane has on thermoacoustic stability. It is found that the friction and the Helmholtz number can change thermoacoustic stability from a linearly stable regime to a linearly unstable regime. The study opens up new possibilities for the accurate prediction of indirect noise in realistic nozzles with implications on both noise emissions and thermoacoustic stability. nozzles with implications on both noise emissions and thermoacoustic stability.

description: The primary nature of the $^{13}$C neutron source is very significant for the studies of the s-process nucleosynthesis. In this paper we present an attempt to fit the element abundances observed in 16 s-rich stars using parametric model of the single neutron exposure. The calculated results indicate that almost all s-elements were made in a single neutron exposure for 9 sample stars. Although a large spread of neutron exposure is obtained, the maximum value of the neutron exposure will reach about 7.0 mbarn$^{-1}$, which is close to the theoretical predictions by the AGB model. The calculated result is a significant evidence for the primary nature of the neutron source. Combining the result obtained in this work and the neutron exposure-initial mass relations, a large spread of neutron exposure can be explained by the different initial stellar mass and their time evolution. The possibility that the rotationally induced mixing process can lead to a spread of the neutron exposure in AGB stars is also existent.

description: Teaching students how to think critically is a key issue of the educational process nowadays because of the abundance of information, the speed of its transmission and the multiplicity of information sources. Based on this assumption, we attempted to study the development of critical thinking in the school subject of Modern Greek History and, more specifically, how teaching practices and the use of appropriate questions by teachers could contribute to such development. The study focused on this particular school subject due to the fact that it is both stimulating and demanding and it has a great impact on our social lives. This paper attempts to investigate whether teachers are pedagogically aware of the appropriate techniques that can be stimulating for students, as well as the extent to which questions are employed as a methodological tool in the teaching of Modern Greek History, in order to cultivate students’ critical and sound reasoning with regard to various issues of contemporary Greek society.

Applications of optimal nonlinear control to a whole-brain network of FitzHugh-Nagumo oscillators

description: We apply the framework of optimal nonlinear control to steer the dynamics of a whole-brain network of FitzHugh-Nagumo oscillators. Its nodes correspond to the cortical areas of an atlas-based segmentation of the human cerebral cortex, and the inter-node coupling strengths are derived from Diffusion Tensor Imaging data of the connectome of the human brain. Nodes are coupled using an additive scheme without delays and are driven by background inputs with fixed mean and additive Gaussian noise. Optimal control inputs to nodes are determined by minimizing a cost functional that penalizes the deviations from a desired network dynamic, the control energy, and spatially non-sparse control inputs. Using the strength of the background input and the overall coupling strength as order parameters, the network's state-space decomposes into regions of low and high activity fixed points separated by a high amplitude limit cycle all of which qualitatively correspond to the states of an isolated network node. Along the borders, however, additional limit cycles, asynchronous states and multistability can be observed. Optimal control is applied to several state-switching and network synchronization tasks, and the results are compared to controllability measures from linear control theory for the same connectome. We find that intuitions from the latter about the roles of nodes in steering the network dynamics, which are solely based on connectome features, do not generally carry over to nonlinear systems, as had been previously implied. Instead, the role of nodes under optimal nonlinear control critically depends on the specified task and the system's location in state space. Our results shed new light on the controllability of brain network states and may serve as an inspiration for the design of new paradigms for non-invasive brain stimulation.

Στην έρευνα αυτή συμμετείχαν 13 άτομα που είχαν χρόνια πάθηση στο ένα ή και στα δύο γόνατα και παρουσίαζαν πόνο στην περιοχή της ΚΓΔ. Από όλα τα άτομα του δείγματος συμπληρώθηκε το ερωτηματολόγιο brief pain inventory για την μέτρηση της έντασης του πόνου στην περιοχή της ΚΓΔ. Στη συνέχεια, έγινε αξιολόγηση της ύπαρξης ή όχι: 1) παρεκτόπισης της κάτω γνάθου, 2) πονοκεφάλου, 3) πόνου στην περιοχή του αυχένα, 4) πόνου ή εμβοών στο εσωτερικό του αυτιού, 5) ήχου στο εσωτερικό της ΚΓΔ και 6) μειωμένης στοματικής διάνοιξης. Για να ελεγχθεί η συσχέτιση της χρόνιας πάθησης του γόνατος με κάθε ένα από τα συμπτώματα του δυσλειτουργικού συνδρόμου της ΚΓΔ, έγινε το τεστ ανεξαρτησίας και ο υπολογισμός του δείκτη χ2. Σε περίπτωση που το στατιστικό κριτήριο χ2 έδωσε p<0.05 υπολογίστηκαν και τα μέτρα συνάφειας για τον έλεγχο της έντασης της συνάφειας μεταξύ των εξεταζόμενων μεταβλητών. Ένα από τα συμπεράσματα της παρούσας εργασίας είναι ότι βρέθηκε στατιστικά σημαντική σχέση μεταξύ της χρόνιας πάθησης του γόνατος και: 1) τη μειωμένη στοματική διάνοιξη, 2) τη μέγιστη και ηπιότερη αντιλαμβανόμενη ένταση του πόνου στην ΚΓΔ, ως διαστάσεις της ύπαρξης δυσλειτουργίας της ΚΓΔ. Σύμφωνα με την ομάδα 1β του Άξονα Ι των Ερευνητικών Διαγνωστικών Κριτηρίων, πόνος στην περιοχή του προσώπου και μειωμένη στοματική διάνοιξη, υποδηλώνουν την ύπαρξη δυσλειτουργίας της ΚΓΔ μυϊκής προέλευσης. Ωστόσο, περαιτέρω έρευνα με μεγαλύτερο δείγμα ενδείκνυται για την καλύτερη τεκμηρίωση των αποτελεσμάτων.
description: The purpose of this study was to investigate the possible association between chronic knee disorder and temporomandibular disorder (TMD), through kinetic chain. In total, 13 patients with chronic knee disorder and temporomandibular joint (TMJ) pain completed the brief pain inventory, for the TMJ’s pain intensity assessment and were examined for the presence of TMD symptoms (mandibular deviation upon mouth opening, headache, cervical pain, ear pain, restricted mouth opening and clicking or grating sounds in the joint upon movements of the mandible). Statistical analysis included Chi-square test and associations’ coefficients calculations for the quantification of dependence’s strength among variables. Results indicated statistically significant relationship among chronic knee disorder with restricted mouth opening and among chronic knee disorder with two BPI’s parameters regarding TMJ’s pain. According to Group 1b of Research Diagnostic Criteria’s Axis I, restricted mouth opening and orofacial pain indicate TMD with muscular origin. However, further research with larger sample is requested for better results’s documentation.

description: Clara Schumann's op. 20 variations and Brahms' op. 9 variations on the same theme are both intensely communciative works. This thesis seeks to discover their emotional content by examining subtle musical and textual clues in the light of Robert Schumann's aesthetic theory and practice, and with in-depth reference to biographical context. The author brings together many threads from pre-existing literature about these works and their composers in order to trace the significance of the shared theme and to explore certain psychological issues surrounding the composition of the two sets of variations. Special attention is given to the tightly-knit internal relationships and the many external references, whether deliberate or unconscious, which enrich the Brahms work.

Two distinctive structural modulations, a major q1= (1/3, 1/3, 2) and a weak q2=q1/10 + (0, 0, 3/2), have been well determined at the temperature of 20K. Systematic analysis demonstrates that the charges at low temperatures are well crystallized in a charge stripe phase, in which the charge density wave behaviors in a non-sinusoidal fashion resulting in elemental electric dipoles for ferroelectricity. It is also noted that the charge ordering and ferroelectric domains often change markedly with lowering temperatures and yields a rich variety of structural phenomena.

description: The success of deep ensembles on improving predictive performance, uncertainty estimation, and out-of-distribution robustness has been extensively studied in the machine learning literature. Albeit the promising results, naively training multiple deep neural networks and combining their predictions at inference leads to prohibitive computational costs and memory requirements. Recently proposed efficient ensemble approaches reach the performance of the traditional deep ensembles with significantly lower costs. However, the training resources required by these approaches are still at least the same as training a single dense model. In this work, we draw a unique connection between sparse neural network training and deep ensembles, yielding a novel efficient ensemble learning framework called FreeTickets. Instead of training multiple dense networks and averaging them, we directly train sparse subnetworks from scratch and extract diverse yet accurate subnetworks during this efficient, sparse-to-sparse training. Our framework, FreeTickets, is defined as the ensemble of these relatively cheap sparse subnetworks. Despite being an ensemble method, FreeTickets has even fewer parameters and training FLOPs than a single dense model. This seemingly counter-intuitive outcome is due to the ultra training/inference efficiency of dynamic sparse training. FreeTickets surpasses the dense baseline in all the following criteria: prediction accuracy, uncertainty estimation, out-of-distribution (OoD) robustness, as well as efficiency for both training and inference. Impressively, FreeTickets outperforms the naive deep ensemble with ResNet50 on ImageNet using around only 1/5 of the training FLOPs required by the latter. We have released our source code at https://github.com/VITA-Group/FreeTickets.

description: Στην παρούσα εργασία επιχειρείται η παρουσίαση δύο μύθων των Ειδυλλίων του Θεοκρίτου, του Κύκλωπα και του Ύλα, χρησιμοποιώντας τα ερμηνευτικά φίλτρα της φιλολογίας και της τέχνης, με σκοπό να ερευνηθεί ο βαθμός επίδρασης του ελληνιστικού ποιητή στην πρόσληψη και εικονιστική μεταφορά των δύο εκδοχών στη ζωγραφική από την περίοδο της Αναγέννησης έως τη Σύγχρονη Τέχνη. Αρχικά, μέσω της φιλολογικής ανάλυσης των μύθων και τη διακειμενική ανάγνωσή τους με τις προϋπάρχουσες και τις μεταθεοκρίτειες παρουσιάσεις επισημαίνονται τα σημεία στα οποία αποκλίνουν και οι καινοτομίες του Θεοκρίτου. Ο βουκολικός κόσμος του βρίσκεται σε συμφωνία με τις νέες αισθητικές θεωρίες, αξίες και αντιλήψεις της ελληνιστικής τέχνης, η οποία λειτουργεί ως καλλιτεχνική προμήτωρ των σημαντικότερων ευρωπαϊκών ρυθμών μετά τον 15ο αι., όσον αφορά όχι μόνο τα τεχνικά χαρακτηριστικά αλλά και την τοποθέτηση του ανθρώπου στο επίκεντρο του ενδιαφέροντος, την έκφραση έντονων συναισθημάτων, τον ερωτισμό, τις σκηνές καθημερινής ζωής. Παρακολουθώντας την καλλιτεχνική παραγωγή από το 1500 έως σήμερα αναλύονται έργα τέχνης των Sebastiano del Piombo, Ραφαήλ, Gustave Moreau, Odilon Redon, Θεοδοσίας Παπαδοπούλου, Joseph Anton Koch, Édouard-Théophile Blanchard, John William Waterhouse και Henrietta Rae με κριτήριο επιλογής το βαθμό πνευματικής συμπόρευσης των ζωγράφων με το λογοτεχνικό πρότυπό τους και τη σύνδεσή τους ως προς το αίσθημα που εκπέμπουν.
description: The present study is about the presentation of two myths of Theocritean Idylls, Cyclops and Hyllas, using the interpretative filters of philology and art so as to examine the Hellenistic poet’s influence to the reception and adaptation of these myths in painting from the Renaissance to Contemporary Art. Initially, through the philological analysis of the myths and their intertextual reading with the preexisting and post-theocritean presentations are indicated Theocritean inclinations and innovations. His bucolic world goes together with the new aesthetic theories, values and conceptions of the Hellenistic art, which works as an artistic pioneer of the most important European styles after the 15th century, as it concerns not only the technical characteristics, but also the placing of man in the center of interest, the emphasis of intense feelings, the eroticism, the scenes of everyday life. Observing art from the 1500’s till now works of Sebastiano del Piombo, Raphael, Gustave Moreau, Odilon Redon, Theodosia Papadopoulou, Joseph Anton Koch, Édouard-Théophile Blanchard, John William Waterhouse and Henrietta Rae are analyzed with criterion the level of intellectual concurrence of the artists with their literary model and the link as far as the emotions they convey.

description: Over the past decade, strong interactions of light and matter at the single-photon level have enabled a wide set of scientific advances in quantum optics and quantum information science. This work has been performed principally within the setting of cavity quantum electrodynamics with diverse physical systems, including single atoms in Fabry-Perot resonators, quantum dots coupled to micropillars and photonic bandgap cavities, and Cooper-pairs interacting with superconducting resonators. Experiments with single, localized atoms have been at the forefront of these advances with the use of optical resonators in high-finesse Fabry-Perot configurations. As a result of the extreme technical challenges involved in further improving the multilayer dielectric mirror coatings of these resonators and in scaling to large numbers of devices, there has been increased interest in the development of alternative microcavity systems. Here we show strong coupling between individual Cesium atoms and the fields of a high-quality toroidal microresonator. From observations of transit events for single atoms falling through the resonator's evanescent field, we determine the coherent coupling rate for interactions near the surface of the resonator. We develop a theoretical model to quantify our observations, demonstrating that strong coupling is achieved, with the rate of coherent coupling exceeding the dissipative rates of the atom and the cavity. Our work opens the way for investigations of optical processes with single atoms and photons in lithographically fabricated microresonators. Applications include the implementation of quantum networks, scalable quantum logic with photons, and quantum information processing on atom chips.

description: If the electroweak Higgs vacuum expectation value $v$ in early universe is $\sim 1 \%$ higher than its present value $v_0=246$ GeV, the $^7$Li puzzle in BBN and the CMB/$Λ$CDM tension with late-universe measurements on Hubble parameter are mitigated. We propose a model of an axion coupled to the Higgs field, named ``axi-Higgs'', with its mass $m_a \sim 10^{-30} - 10^{-29}\,{\rm eV}$ and decay constant $f_a \sim 10^{17} - 10^{18}\,{\rm GeV}$, to achieve this goal. The axion initial value $a_{\rm ini}$ yields an initial $Δv_{\rm ini}/v_0 \sim 0.01$ throughout the BBN-recombination epoch and a percent level contribution to the total matter density today. Because of its very large de Broglie wavelength, this axion matter density $ω_a$ suppresses the matter power spectrum, alleviating the CMB/$Λ$CDM $S_8/σ_8$ tension with the weak-lensing data. It also explains the recently reported isotropic cosmic birefringence by its coupling with photons. Adding the axion ($m \sim 10^{-22}\,$eV) in the fuzzy dark matter model to the axi-Higgs model allows bigger $Δv_{\rm rec}$ and $ω_a$ to address the Hubble and $S_8/σ_8$ tensions simultaneously. The model predicts that $Δv$ may be detected by the spectral measurements of quasars, while its oscillation may be observed in the atomic clock measurements.

description: We show that fractional decay may be observable in experiments using quantum dots and photonic crystals with parameters that are currently achievable. We focus on the case of inverse opal photonic crystals and locate the position in the crystal where the effect is most pronounced. Furthermore, we quantify the influence of absorptive loss and show that it is a limiting but not prohibitive effect.

description: Το εκπαιδευτικό Δράμα παρόλο που έχει σημαντικά αποτελέσματα να επιδείξει τόσο στην ένταξη των παιδιών, όσο και στη μάθηση, ακόμα παλεύει για την αναγνώρισή του ως τμήμα της σχολικής καθημερινότητας. Οι μαθητές μέσα από το εκπαιδευτικό Δράμα μαθαίνουν να λειτουργούν συνεργατικά και όχι ανταγωνιστικά, να προσεγγίζουν τη γνώση βιωματικά με συναισθηματική εμπλοκή, να επιλύουν προβλήματα και να παίρνουν αποφάσεις, να αποκτούν ενσυναίσθηση και να αναγνωρίζουν το διαφορετικό. Στην παρούσα εργασία προσεγγίζεται αρχικά το θεωρητικό πλαίσιο του εκπαιδευτικού Δράματος. Δίνεται ο ορισμός του, ανιχνεύονται οι καταβολές του και παρουσιάζεται η δομή του. Η θεωρία μάθησης του εποικοδομισμού και η κοινωνικο-πολιτιστική θεωρία συνθέτουν τα ψυχοπαιδαγωγικά θεμέλια του Δράματος. Αντίστοιχα η μέθοδος Στανισλάφσκι, η μπρεχτική αποστασιοποίηση και το κοινωνικό θέατρο ορίζουν τις τεχνικές και τα μέσα του Δράματος. Στο δεύτερο μέρος της εργασίας καταγράφεται η προσπάθεια ένταξης τριών παιδιών στην ομάδα των συνομηλίκων μέσα από ένα πρόγραμμα εκπαιδευτικού Δράματος που εκπονήθηκε από εκπαιδευτικό ειδικής αγωγής και θεατρολόγο. Αναλύονται οι στόχοι κάθε συνάντησης και οι ασκήσεις που επιλέχτηκαν βάσει αυτών των στόχων, ώστε η παράσταση στο τέλος να εξαχθεί μέσα από τους μαθητές της τάξης και να λειτουργήσει ως μία διαδικασία συλλογικής προσπάθειας και κοινωνικής ένταξης.
description: Even though Educational Drama has significant implications in inclusion and in learning, it still struggles for a place in school’s everyday life. Students through Educational Drama learn to cooperate and not to compete each other, to approach knowledge via experiential learning, with emotional involvement, to solve problems, to take decisions, to acquire empathy, and to recognize otherness. In this paper, the theoretical context of Educational Drama, definitions, origin, and structure are initially given. The learning theory of constructuralism, the socio-cultural theory, consist the psycho-pedagogical foundations of Drama. Also, the Stanislavski method, Brecht’s detachment and the social theatre, define the technics and the means of Drama. A Drama-based included programme by the special education and theatre teacher for tree students in the peer group is presented in the second part of the paper. The goals of each meeting and the chosen tasks based on these goals are presented and analyzed. In the end, the performance emerged from the students of the class and the process of drama operated as a process of collective work and achievement of social inclusion.

description: We consider two-stage inflationary models in which a superheavy scale F-term hybrid inflation is followed by an intermediate scale modular inflation. We confront these models with the restrictions on the power spectrum P_R of curvature perturbations and the spectral index n_s implied by the recent data within the power-law cosmological model with cold dark matter and a cosmological constant. We show that these restrictions can be met provided that the number of e-foldings N_HI* suffered by the pivot scale k_*=0.002/Mpc during hybrid inflation is appropriately restricted. The additional e-foldings required for solving the horizon and flatness problems can be naturally generated by the subsequent modular inflation. For central values of P_R and n_s, we find that, in the case of standard hybrid inflation, the values obtained for the grand unification scale are close to its supersymmetric value M_GUT=2.86 x 10^16 GeV, the relevant coupling constant is relatively large (0.005-0.14), and N_HI* between about 10 and 21.7. In the case of shifted [smooth] hybrid inflation, the grand unification scale can be identified with M_GUT provided that N_HI*=21 [N_HI*=18].

description: We study the Euclidean path integral of two-dimensional quantum gravity with positive cosmological constant coupled to conformal matter with large and positive central charge. The problem is considered in a semiclassical expansion about a round two-sphere saddle. We work in the Weyl gauge whereby the computation reduces to that for a (timelike) Liouville theory. We present results up to two-loops, including a discussion of contributions stemming from the gauge fixing procedure. We exhibit cancelations of ultraviolet divergences and provide a path integral computation of the central charge for timelike Liouville theory. Combining our analysis with insights from the DOZZ formula we are led to a proposal for an all orders result for the two-dimensional gravitational partition function on the two-sphere.

description: Using a recently developed perturbative approach, which considers Hubbard operators as fundamental excitations, we have performed electronic self-energy and spectral function calculations for the $t-J$ model on the square lattice. We have found that the spectral functions along the Fermi surface are isotropic, even close to the critical doping where the $d$-density wave phase takes place. Fermi liquid behavior with scattering rate $\sim ω^2$ and a finite quasiparticle weight $Z$ was obtained. $Z$ decreases with decreasing doping taking low values for low doping. Results are compared with other ones, analytical and numerical like slave-boson and Lanczos diagonalization finding agreement. We discuss our results in the light of recent $ARPES$ experiments in cuprates.

description: A magnetic vortex is a curling magnetic structure realized in a ferromagnetic disk, which is a promising candidate of a memory cell for future nonvolatile data storage devices. Thus, understanding of the stability and dynamical behaviour of the magnetic vortex is a major requirement for developing magnetic data storage technology. Since the experimental proof of the existence of a nanometre-scale core with out-of-plane magnetisation in the magnetic vortex, the dynamics of a vortex has been investigated intensively. However, the way to electrically control the core magnetisation, which is a key for constructing a vortex core memory, has been lacking. Here, we demonstrate the electrical switching of the core magnetisation by utilizing the current-driven resonant dynamics of the vortex; the core switching is triggered by a strong dynamic field which is produced locally by a rotational core motion at a high speed of several hundred m/s. Efficient switching of the vortex core without magnetic field application is achieved thanks to resonance. This opens up the potentiality of a simple magnetic disk as a building block for spintronic devices like a memory cell where the bit data is stored as the direction of the nanometre-scale core magnetisation.
