description: Interface of transition metal dichalcogenide (TMDC) and high-k dielectric transition metal oxides (TMO) had triggerred umpteen discourses due to the indubitable impact of TMO in reducing the contact resistances and restraining the Fermi-level pinning for the metal-TMDC contacts. In the present work, we focus on the unresolved tumults of large-area TMDC/TMO interfaces, grown by adopting different techniques. Here, on a pulsed laser deposited (PLD) MoS2 thin film, a layer of TiO2 is grown by using both atomic layer deposition (ALD) and PLD. These two different techniques emanate TiO2 layers with different crystalline properties, thicknesses and interfacial morphologies, subsequently influencing the electronic and optical properties of the interfaces. In addition, they manifest a boost in the extent of p-type doping with increasing thickness of TiO2, as emerged after analyzing the core-level shifts of the X-ray photoelectron spectra (XPS). Density functional analysis of the MoS2/Anatase-TiO2 interfaces, for pristine and in presence of a wide range of interfacial defects, could explain the interdependence of doping and the terminating atomic-surface of TiO2 on MoS2. The optical properties of the interface, encompassing the photoluminescence, transient absorption and z-scan two-photon absorption indicate the presence of defect-induced localized mid-gap levels in MoS2/TiO2 (PLD), resulting quenched exciton signals. On the contrary, the relatively defect-free interface in MoS2/TiO2 (ALD) demonstrates a clear presence of both A and B excitons of MoS2. From the investigation of optical properties, we indicate that MoS2/TiO2 (PLD) interface may act as a promising saturable absorber. Moreover, MoS2/TiO2 (PLD) interface had resulted a better photo-transport. A potential application of MoS2/TiO2 (PLD) is demonstrated by the fabrication of a p-type photo-transistor with the ionic-gel top gate.

description: A scheme is presented for realizing frequency-up conversion and a two-qubit quantum swap gate for intracavity fields. In the scheme, a V-type atomic ensemble prepared in their ground states collectively mediates the interaction between the two cavity modes. Under certain conditions, the cavity-field degree of freedom is decoupled from the atomic degrees of freedom, and the effective coupling strength between the two cavity modes scales up with $\sqrt{N}$ ($N$ is the number of atoms). The numerical simulation shows that the quantum swap gate still has a high fidelity under the influence of the atomic spontaneous emission and the decay of the cavity modes.

description: Kinetic Monte Carlo simulations are performed to study the influence of external magnetic fields on the growth of magnetic fcc binary alloy nanoclusters with perpendicular magnetic anisotropy. The underlying kinetic model is designed to describe essential structural and magnetic properties of CoPt_3-type clusters grown on a weakly interacting substrate through molecular beam epitaxy. The results suggest that perpendicular magnetic anisotropy can be enhanced when the field is applied during growth. For equilibrium bulk systems a significant shift of the onset temperature for L1_2 ordering is found, in agreement with predictions from Landau theory. Stronger field induced effects can be expected for magnetic fcc-alloys undergoing L1_0 ordering.

description: The glass transition temperature and relaxation dynamics of the segmental motions of thin films of polystyrene labeled with a dye, 4-[N-ethyl-N-(hydroxyethyl)]amino-4-nitraozobenzene (Disperse Red 1, DR1) are investigated using dielectric measurements. The dielectric relaxation strength of the DR1-labeled polystyrene is approximately 65 times larger than that of the unlabeled polystyrene above the glass transition, while there is almost no difference between them below the glass transition. The glass transition temperature of the DR1-labeled polystyrene can be determined as a crossover temperature at which the temperature coefficient of the electric capacitance changes from the value of the glassy state to that of the liquid state. The glass transition temperature of the DR1-labeled polystyrene decreases with decreasing film thickness in a reasonably similar manner to that of the unlabeled polystyrene thin films. The dielectric relaxation spectrum of the DR1-labeled polystyrene is also investigated. As thickness decreases, the $α$-relaxation time becomes smaller and the distribution of the $α$-relaxation times becomes broader. These results show that thin films of DR1-labeled polystyrene are a suitable system for investigating confinement effects of the glass transition dynamics using dielectric relaxation spectroscopy.

description: Le esigenze sempre piu' esasperate e le contunue evoluzioni dell'Elettronica hanno fatto in modo che la tecnica della Progettazione dei Circuiti Stampati subisse in questi ultimi dieci anni una trasformazione radicale, passando dalla lavorazione strettamente manuale a quella completamente automatica. La Progettazione Computerizzata dei Circuiti Stampati, pertanto, rappresenta oggi quanto di meglio la tecnologia possa offrire alle complesse esigenze dell'Elettronica. L'esasperata riduzione dello spazio, la continua lotta con il tempo verso l'apparato piu' sofisticato e la qualita' del prodotto finale richiedono un insieme di potenzialita' che solo un attrezzatura molto evoluta puo' avere. Computer e Software oggi permettono una egregia risoluzione di queste tre incompatibili richieste, consentendo un rapporto qualita'-prezzo talmente elevato che qualche anno fa era addirittura inconcepibile. Ed e' proprio sulla base di tali risultati e sulla consapevolezza che uno strumento del genere debba essere alla portata di tutti nell'ambito della Ricerca, si e' ritenuto opportuno creare un documento semplice e schematico sull'argomento. Pertanto tutti coloro che non hanno mai lavorato con strumenti di Progettazione Computerizzata, ma che comunque hanno una discreta conoscenza del sistema operativo delle Vax Station Digital, potranno, tramite questa pubblicazione, facilmente apprendere e molto rapidamente realizzare il proprio circuito. Inoltre nella convinzione che il metodo piu' stimolante ed efficace per l'apprendimento sia quello di dare una traccia chara e semplice del procedimento da seguire, si e' ritenuto opportuno, nei vari paragrafi, di mostrare in modo sequenziale tutto cio' che appare sul monitor, dal momento in cui si e' fatto partire il software fino alla completa realizzazione del circuito stampato. Si vuole inoltre sottolineare un particolare ringraziamento al Prof. Roumen Iltchev che con la sua squisita collaborazione ha permesso all'INFN di poter utilizzare ed apprezzare uno strumento cosi fondamentale per la Progettazione Elettronica.

description: Object recognition is a key enabler across industry and defense. As technology changes, algorithms must keep pace with new requirements and data. New modalities and higher resolution sensors should allow for increased algorithm robustness. Unfortunately, algorithms trained on existing labeled datasets do not directly generalize to new data because the data distributions do not match. Transfer learning (TL) or domain adaptation (DA) methods have established the groundwork for transferring knowledge from existing labeled source data to new unlabeled target datasets. However, current DA approaches assume similar source and target feature spaces and suffer in the case of massive domain shifts or changes in the feature space. Existing methods assume the data are either the same modality, or can be aligned to a common feature space. Therefore, most methods are not designed to support a fundamental domain change such as visual to auditory data. We propose a novel deep learning framework that overcomes this limitation by learning separate feature extractions for each domain while minimizing the distance between the domains in a latent lower-dimensional space. The alignment is achieved by considering the data manifold along with an adversarial training procedure. We demonstrate the effectiveness of the approach versus traditional methods with several ablation experiments on synthetic, measured, and satellite image datasets. We also provide practical guidelines for training the network while overcoming vanishing gradients which inhibit learning in some adversarial training settings.

description: We analyze electromagnetic modes in multi-layered nano-composites and demonstrate that the response of a majority of realistic layered structures is strongly affected by the non-local effects originating from strong field oscillations across the system, and is not described by conventional effective-medium theories. We develop the analytical description of the relevant phenomena and confirm our results with numerical solutions of Maxwell equations. Finally, we use the developed formalism to demonstrate that multi-layered plasmonic nanostructures support high-index volume modes, confined to deep subwavelength areas, opening a wide class of applications in nanoscale light management.

description: Optics is a promising platform in which to help realise the next generation of fast, parallel and energy-efficient computation. We demonstrate a reconfigurable free-space optical multiplier that is capable of over 3000 computations in parallel, using spatial light modulators with a pixel resolution of only 340x340. This enables vector-matrix multiplication and parallel vector-vector multiplication with vector size of up to 56. Our design is the first to simultaneously support optical implementation of reconfigurable, large-size and real-valued linear algebraic operations. Such an optical multiplier can serve as a building block of special-purpose optical processors such as optical neural networks and optical Ising machines.

description: The apparatus of correlation gamma function (Γ*(r)) is used to analyze volume-limited samples from the DR4 Main Galaxy Sample of the SDSS survey with the aim of determining the characteristic scales of galaxy clustering. Up to 20 h^{-1} Mpc (H_0 = 65 km s^{-1}Mpc^{-1}), the distribution of galaxies is described by a power-law density-distance dependence, Γ*(r) proportional to r^{-γ}, with an index γapproximately 1.0. A change in the state of clustering (a significant deviation from the power law) was found on a scale of 20-25 h^{-1}Mpc. The distribution of SDSS galaxies becomes homogeneous (γapproximately 0) from a scale of ~60 h^{-1}Mpc. The dependence of γon the luminosity of galaxies in volume-limited samples was obtained. The power-law index γincreases with decreasing absolute magnitude of sample galaxies M_abs. At M_abs ~ -21.4, which corresponds to the characteristic value Mr* of the SDSS luminosity function, this dependence exhibits a break followed by a more rapid increase in γ.

description: We present a variational wavefunction which explains the behaviour of the supersolid state formed by hard-core bosons on the triangular lattice. The wavefunction is a linear superposition of {\em only and all} configurations minimising the repulsion between the bosons (which it thus implements as a hard constraint). Its properties can be evaluated exactly--in particular, the variational minimisation of the energy yields (i) the surprising and initially controversial spontaneous density deviation from half-filling (ii) a quantitatively accurate estimate of the corresponding density wave (solid) order parameter.

description: The ATLAS phase-I upgrade aims to enhance event trigger performance in the Liquid Argon (LAr) calorimeter and the forward muon spectrometer. The trigger signals are transmitted by optical transceivers at 5.12 Gbps per channel in a radiation field. We report the design, quality control in production and ageing test of the transceivers fabricated with the LOCld laser driver and multi-mode 850 nm vertical-cavity surface-emitting laser (VCSEL). The modules are packaged in miniature formats of dual-channel transmitter (MTx) and transceiver (MTRx) for the LAr. The transmitters are also packaged in small form-factor pluggable (SFP) for the muon spectrometer. In production, the LOCld chips and VCSELs in TOSA package were examined before assembly. All of the modules were tested and selected during production for quality control based on the eye-diagram parameters measured at 5.12 Gbps. The yield is 98 % for both the MTx and MTRx on a total 4.7k modules. The uniformity of transmitter channels of a MTx was assured by choosing the TOSA components with approximately equal light powers. The ageing effect is monitored in burn-in of a small batch of transmitter modules with bit-error test and eye-diagrams measured periodically. The observables are stable with the light power degradation within 5 % over a period of more than 6k hours.

description: We perform rescaled range analysis upon the signals measured by Dual Particle Dynamical Analyzer in gas-liquid two-phase turbulent jets. A novel rescaled range analysis is proposed to investigate these unevenly sampled signals. The Hurst exponents of velocity and other passive scalars in the bulk of spray are obtained to be 0.59$\pm $0.02 and the fractal dimension is hence 1.41$\pm $ 0.02, which are in remarkable agreement with and much more precise than previous results. These scaling exponents are found to be independent of the configuration and dimensions of the nozzle and the fluid flows. Therefore, such type of systems form a universality class with invariant scaling properties.

Exact Christoffel-Darboux Expansions: A New, Multidimensional, Algebraic, Eigenenergy Bounding Method

description: Although the Christoffel-Darboux representation (CDR) plays an important role within the theory of orthogonal polynomials, and many important bosonic and fermionic multidimensional Schrodinger equation systems can be transformed into a moment equation representation (MER), the union of the two into an effective, algebraic, eigenenergy bounding method has been overlooked. This particular fusion of the two representations, suitable for bounding bosonic or fermionic systems, defines the Orthonormal Polynomial Projection Quantization - Bounding Method (OPPQ-BM), as developed here. We use it to analyze several one dimensional and two dimensional systems, including the quadratic Zeeman effect for strong-superstrong magnetic fields. For this problem, we match or surpass the excellent, but intricate, results of Kravchenko et al (1996 Phys. Rev. A 54287) for a broad range of magnetic fields, without the need for any truncations or approximations.

Disrupting the practice of the elementary school administrator: a reflection on Noddings' challenge to care
Creators: name: Grunlund, Cathy
Publisher: name: University of British Columbia
Year: 2009

description: Nel Noddings in her book The Challenge to Care (1992) presents a philosophy based on an ethic of care and a theory for educational practice that is at once intriguing and satisfyingly resonant. While Noddings describes her notion of caring in terms of practice it is clear that Noddings is grounding this in a philosophical framework rather than in the real and current life of schools. The problem I have attempted to address is whether or not caring, however logical it may appear in my mind, is a reasonable ethic to consciously incorporate into the art of educating children. Specifically I looked at the practice of the elementary school vice-principal by reflecting on my own experience and my attempts to live arid model caring as an important way of being with children and adults who work and learn in schools. I came to this investigation from a point of dissatisfaction with many of the accepted ways of acting within the practice of educational administration. This work is written in the style of story. Noddings' ideas have been taken and situated within the context of my experience and analyzed through narrative. Relevant research has been brought to bear to help support or critically discuss concepts. Chapter 1 discusses some of the problems I saw as inherent within the world of educational administration and of my search for alternative action. Chapter 2 attempts to conceptualize caring in a manner that will make it more comprehensible to educational practitioners. Chapter 3 looks at caring in practice, specifically discussing Noddings' notion of moral education. How caring fits into the larger discussion of moral education is discussed in Chapter 4 with caring being placed in relief to other ethical approaches as they relate to education. The final chapter discusses the implications for educational leaders who would like to work towards a more caring approach to the education of children. It is my hope that educators who read this story will be tempted to disrupt their practice long enough to think about the moral issues inherent in the roles of teachers and principal teachers. The point I have tried to make is that these moral issues are not purely philosophical in nature but have significant impact on the lives and moral development of real children in our schools.

description: We describe the non-relativistic time evolution of an ultra-cold degenerate quantum gas (bosons/fermions) falling in Earth's gravity during long times (10 sec) and over large distances (100 m). This models a drop tower experiment that is currently performed by the QUANTUS collaboration at ZARM (Bremen, Germany). Starting from the classical mechanics of the drop capsule and a single particle trapped within, we develop the quantum field theoretical description for this experimental situation in an inertial frame, the corotating frame of the Earth, as well as the comoving frame of the drop capsule. Suitable transformations eliminate non-inertial forces, provided all external potentials (trap, gravity) can be approximated with a second order Taylor expansion around the instantaneous trap center. This is an excellent assumption and the harmonic potential theorem applies. As an application, we study the quantum dynamics of a cigar-shaped Bose-Einstein condensate in the Gross-Pitaevskii mean-field approximation. Due to the instantaneous transformation to the rest-frame of the superfluid wave packet, the long-distance drop (100m) can be studied easily on a numerical grid.

description: The aging behavior of polymer glass, poly(methyl methacrylate), has been investigated through the measurement of ac dielectric susceptibility ata fixed frequency after a temperature shift $ΔT$ ($\le $ 20 K)between two temperatures, $T_1$ and $T_2$. A crossover from cumulative aging to non-cumulative aging could be observed with increasing $ΔT$ using a twin temperature ($T$-) shift measurement. Based on a growth law of a dynamical coherent length given by activated dynamics, we obtained a unique coherent length for positive and negative $T$-shifts. The possibility of the existence of temperature chaos in polymer glasses is discussed.

description: The present M.Sc. Thesis includes six chapters, as follows: The first chapter includes the scope, objective and content of the research. In the second section there is a numeric estimation of quality values of road accidents especially in Europe, and we give a descriptive approach about the level of road security In section three there is a reference to the meaning of the term road accident cost and also road accident cost categories. Considering human life as priceless and using statistical data of road accidents for Greece and Europe, it is stressed how important is to find the right methods to estimate road accident cost. Section four describes analytical methodologies of estimating road accident cost. Section five describes the application of those methodologies in various countries aiming at better understanding of how they work and adapt to reality. Their application leads to an economic approach of road accident cost where quality values can be measured in terms of money. The sixth chapter includes the findings and conclusions of the research .

description: M-theory is known to possess supersymmetric solutions where the geometry is $\mathrm{AdS}_3\times S^3\times S^3$ warped over a Riemann surface $Σ_{2}$. The simplest examples in this class can be engineered by placing M2 and M5 branes as defects inside of a stack of background M5 branes. In this paper we show that a generalization of this construction yields more general solutions in the aforementioned class. The background branes are now M5's carrying M2 brane charge, while the defect branes are now placed at the origin of a flat hyperplane with a conical defect. The equations of motion imply a relation between the deficit angle produced by the conical defect and the M2 charge carried by the background branes.

description: We study from first principles the magnetism in graphene induced by single carbon atom defects. For two types of defects considered in our study, the hydrogen chemisorption defect and the vacancy defect, the itinerant magnetism due to the defect-induced extended states has been observed. Calculated magnetic moments are equal to 1 $μ_B$ per hydrogen chemisorption defect and 1.12$-$1.53 $μ_B$ per vacancy defect depending on the defect concentration. The coupling between the magnetic moments is either ferromagnetic or antiferromagnetic, depending on whether the defects correspond to the same or to different hexagonal sublattices of the graphene lattice, respectively. The relevance of itinerant magnetism in graphene to the high-$T_C$ magnetic ordering is discussed.

Glassy dynamics in thin films of polystyrene
Creators: name: Fukao, Koji

Publisher: name: arXiv
Year: 2008
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Glassy dynamics was investigated for thin films of atactic polystyrene by complex electric capacitance measurements using dielectric relaxation spectroscopy. During the isothermal aging process the real part of the electric capacitance increased with time, whereas the imaginary part decreased with time. It follows that the aging time dependences of real and imaginary parts of the electric capacitance were primarily associated with change in volume (film thickness) and dielectric permittivity, respectively. Further, dielectric permittivity showed memory and rejuvenation effects in a similar manner to those observed for poly(methyl methacrylate) thin films. On the other hand, volume did not show a strong rejuvenation effect.

description: Αντικείμενο της παρούσας εργασίας είναι να εφαρμόσει και να διερευνήσει την αποτελεσματικότητα των εννοιολογικών χαρτών σε πραγματικές συνθήκες εκπαίδευσης και να εξετάσει τη συμβολή της στη μάθηση με νόημα. Πιο συγκεκριμένα, σχεδιάστηκαν εκπαιδευτικές δραστηριότητες που σκοπό είχαν να εξετάσουν τους εννοιολογικούς χάρτες ως εργαλεία: (α) μάθησης, (β) διδασκαλίας, (γ) αξιολόγησης και (δ) συνεργασίας. Οι δραστηριότητες σχεδιάστηκαν κατάλληλα προσαρμοσμένες για τις ανάγκες του εκπαιδευτικού πλαισίου στο οποίο εφαρμόστηκαν και το οποίο αφορούσε μαθητές Β' Τάξης ΕΠΑ.Λ της κατεύθυνσης Πληροφορικής & Δικτύων. Το εκπαιδευτικό σενάριο που εφαρμόστηκε περιελάμβανε τόσο ατομικές όσο και συνεργατικές δραστηριότητες. Το εργαλείο εννοιολογικών χαρτών που επιλέχθηκε και χρησιμοποιήθηκε για την υλοποίηση των δραστηριοτήτων ήταν το CmapTools. Η αξιολόγηση που ακολούθησε σκοπό είχε να εξετάσει τόσο το μαθησιακό αποτέλεσμα όσο και την αποτελεσματικότητα και λειτουργικότητα του εργαλείου. Τα συμπεράσματα που προέκυψαν αναδεικνύουν τη δυναμική των εννοιολογικών χαρτών στα πλαίσια διδασκαλίας μαθημάτων σε συνδυασμό με την παραδοσιακή μέθοδο, αλλά και προβληματισμούς για την αναγκαιότητα δημιουργίας κατάλληλων συνθηκών για την επιτυχή εφαρμογή τους στο εκπαιδευτικό πλαίσιο της διδασκαλίας στη δευτεροβάθμια εκπαίδευση.
description: The subject of this dissertation is to apply and examine the effectiveness of concept maps in real life education and to study the contribution of education to meaningful learning. More concretely, educational activities were drawn that aim to examine concept maps as tools of: (a) learning, (b) teaching, (c) evaluation and (d) collaboration. The activities were drawn suitably adapted to the needs of the educational frame in which they were applied and which concerned second year students of a greek technical high school in the direction of Information technology and Networks. The educational script that was applied included both individual and collaborative activities. The tool of concept maps that was selected and used for the materialization of activities was CmapTools. The evaluation that followed aimed to examine the learning result as well as the effectiveness and functionality of the tool. The conclusions of this evaluation show the dynamics of concept maps in the frames of teaching of courses in combination with the traditional method, but also reflections on the necessity of creation of suitable conditions for their successful application in the educational frame of secondary teaching.

description: Η ανακάλυψη του φουλερενίου από τους Kroto κ.α. οδήγησε στη συνειδητοποίηση ότι άτομα μπορούν να τοποθετηθούν εντός του κλωβού του φουλερενίου. Αυτό το γεγονός έχει μεγάλη σημασία καθώς για να αναπτυχθεί η οικονομία του υδρογόνου είναι απαραίτητο να αναπτυχθούν αποτελεσματικοί τρόποι αποθήκευσης του υδρογόνου. Μέχρι σήμερα έχει αναφερθεί η θεωρητική δυνατότητα για τοποθέτηση 2-57 υδρογόνων εντός του φουλερενίου. Σε αυτή τη μελέτη χρησιμοποιήσαμε car parinello κβαντικές μοριακές προσομοιώσεις με το CPMD λογισμικό. Χρησιμοποιήθηκαν οι υπερυπολογιστές του Α.Π.Θ. για τους υπολογισμούς χρησιμοποιώντας 2.16.26.38, 50 και 58 άτομα υδρογόνου. Τα υδρίδια του φουλερενίου μελετήθηκαν στους 122 και 300 βαθμούς Kelvin που αποτελούν και τις ακραίες θερμοκρασίες στον πλανήτη Άρη. Οι μοριακές προσομοιώσεις έλαβαν χώρα σε κανονικό σύνολο. Η μέγιστη θεωρητική χωρητικότητα του φουλερενίου σε υδρογόνο υπολογίστηκε σε 50 άτομα στους 122 K. Η θερμοκρασία παίζει κρίσιμο ρόλο καθώς για 50 υδρογόνα το σύστημα αποτυγχάνει για τους 300 Κ Επιπλέον για περισσότερα από 50 υδρογόνα εντός του φουλερενίου το σύστημα αστοχεί και για τις δύο θερμοκρασίες. Ο μηχανισμός θραύσης περιγράφεται με τη χρήση μοριακών προσομοιώσεων πρώτης αρχής.
description: The discovery of fullerene by Kroto et al lead to the realization that atoms can be caged inside fullerene. The caging of fullerene has great importance due to the fact that hydrogen economy needs efficient storage devices in order to be fully deployed. Till today there are 2-57 reported hydrogen atoms that can theoretically be caged inside fullerene. In this study we used car parinello ab initio molecular dynamics with the use of CPMD software. GRID infrastructure of AUTH was used for the computational demands. We used 2, 16, 26, 38, 50, and 58 hydrogen atoms. Fullerene hydrids were studied in 122 K and 300 K which are the Mars planet extreme temperature. MD’s were deployed at NVT ensemble. The maximum calculated capacity of fullerene in hydrogen was 50 atoms at 122 K. Temperature plays critical role because at 50 hydrogen atoms at 300 K the fullerene fails. Moreover the for more than 50 hydrogen atoms the fullerene fails as storage device for both temperatures. The failure mechanism is also described with the help of ab initio molecular dynamics.
The Aharonov-Bohm effect: the role of tunneling and associated forces

description: Through tunneling, or barrier penetration, small wavefunction tails can enter a finitely shielded cylinder with a magnetic field inside. When the shielding increases to infinity the Lorentz force goes to zero together with these tails. However, it is shown, by considering the radial derivative of the wavefunction on the cylinder surface, that a flux dependent force remains. This force explains in a natural way the Aharonov-Bohm effect in the idealized case of infinite shielding.

description: In this paper we summarize the ellipsoidally symmetric Buda-Lund model's results on HBT radii. We calculate the Bose-Einstein correlation function from the model and derive formulas for the transverse momentum dependence of the correlation radii in the Bertsch-Pratt system of out, side and longitudinal directions. We show a comparison to $\sqrt{s_{\rm NN}}=200 GeV$ RHIC PHENIX two-pion correlation data and make prediction on the same observable for different particles.
