description: Schülerinnen und Schüler mit Deutsch als Zweitsprache (DAZ-SuS) haben ein riesiges Sprachlernvolumen zu bewältigen. Dies zeigt sich verstärkt im Frühfremdsprachunterricht Englisch oder Französisch. So stehen die DaZ-SuS vor der Herausforderung, eine weitere Fremdsprache in einer Fremdsprache lernen zu müssen.Im Rahmen der vorliegenden Arbeit wurde eine virtuelle Lerneinheit (VRLe) für das Kommunizieren in Französisch für Kinder mit Deutsch als Zweitsprache (DaZ) bei Anwendung des Lehrmittels «dis donc!» entwickelt und mit fünf DaZ-Kindern einer sechsten Klasse getestet. Es wurde untersucht, wie sich die VRLe auf die Motivation auswirkt und inwiefern sie den DaZ-SuS einen niederschwelligen Zugang zum Kommunizieren ermöglicht.Die Forschung in dieser Masterarbeit wurde nach dem «Design Science Research» aufgebaut. Sie vereint aktuelle Sprachlern- und Verhaltenstheorien sowie Gestaltungsaspekte rund um Virtual Reality. In vier Feldtestungen wurden diagnostische Verfahren wie direkte Verhaltensbeobachtung, FlowKurzfragebogen sowie verschiedene Interviews eingesetzt.Es konnte aufgezeigt werden, dass sich die spezifisch für die DaZ-SuS entwickelte VRLe positiv sowohl auf die Motivation der SuS als auch auf das sichere und deutliche Sprechen der Fremdsprache Französisch auswirkte. Verschiedene in der VRLe eingesetzte Scaffolds (Hilfestellungen) erwiesen sich dabei als wirksam. Als die bei den DaZ SuS beliebtesten Scaffolds prägten sich die Erklärungen in ihrer Erstsprache (L1), das modellierte Nachsprechen sowie die Bildunterstützung in Form von eingeblendeten Dialogfenstern aus.Die Daten dieser Studie zeigen einerseits ein grosses Potential VRLe für den passgenauen Fremdspracherwerb von DaZ-SuS auf. Andererseits brachte die Studie auch deutlich hervor, dass die Entwicklung von VRLe eine multidisziplinäre und zeitaufwändige Herausforderung ist.

description: Το ερευνητικό πεδίο της επιστήμης των δικτύων παρουσιάζει ραγδαία ανάπτυξη τα τελευταία χρόνια σε διάφορες επιστήμες, κυρίως λόγω της ιδιαίτερης προόδου της Τεχνολογίας, καθώς και της αυξανόμενης ανάγκης της επιστήμης της πληροφορικής στην ζωή μας. Το αποτέλεσμα αυτής της εξέλιξης είναι η παραγωγή και η δημοσίευση ενός μεγάλου πλήθους επιστημονικών εργασιών και δημιουργία δικτύων μεταξύ των επιστημόνων. Στην παρούσα διπλωματική εργασία, γίνεται ανάλυση δεδομένων των προγραμμάτων Erasmus, χρησιμοποιώντας τη θεωρία γραφημάτων και δικτύων. Οι διοργανώτριες χώρες, καθώς και οι χώρες που συμμετέχουν ανά πρόγραμμα δίνουν τις πληροφορίες που αποτελούν τα δεδομένα. Η ανάπτυξη ενός προγράμματος στη γλώσσα προγραμματισμού Python, συνέβαλε στην ανάπτυξη ενός δικτύου βαρών – σχέσεων μεταξύ των χωρών. Το πρόγραμμα αναπτύχθηκε με σκοπό να εξεταστεί ποιες χώρες συνεργάζονται και ποιες χώρες συμμετέχουν πιο συχνά στα προγράμματα Erasmus. Επιπλέον, αναπτύχθηκε ένα πρόγραμμα, το οποίο συλλέγει αρχεία excel και δημιουργεί δίκτυα ώστε να αναλύονται και να επεξεργάζονται για την εξαγωγή συμπερασμάτων. Για την ανάλυση του δικτύου υπολογίστηκαν ορισμένα μέτρα κεντρικότητας, όπου έχουν καθοριστικό ρόλο στην εξαγωγή των συμπερασμάτων της παρούσας διπλωματικής εργασίας.
description: The field of network research has shown rapid growth in recent years in various sciences, mainly due to the particular advancement of Technology, as well as the growing need for computer science in our lives. The result of this development is the production and publication of a large number of scientific papers and the creation of networks between scientists. In this dissertation, data of Erasmus programs are analyzed, using the theory of graphs and networks. The host countries, as well as the countries participating per program give the information which constitutes the data. The development of a program in the python programming language, contributed to the development of a network weights – relations between countries. The program was developed to examine which countries cooperate and countries most often in Erasmus programs. In addition, the program was developed to collect excel files and create networks to analyze and edit the outcome of conclusions. For the analysis of the networks some centrality measures have been calculated, where they have the decisive role in drawing the conclusions of the present dissertation.

description: We analyse our recently-published velocity measurements of alpha Cen A (Butler et al. 2004). After adjusting the weights on a night-by-night basis in order to optimize the window function to minimize sidelobes, we extract 42 oscillation frequencies with l=0 to 3 and measure the large and small frequency separations. We give fitted relations to these frequencies that can be compared with theoretical models and conclude that the observed scatter about these fits is due to the finite lifetimes of the oscillation modes. We estimate the mode lifetimes to be 1-2 d, substantially shorter than in the Sun.

description: Support Vector Machines (SVMs) can solve structured multi-output learning problems such as multi-label classification, multiclass classification and vector regression. SVM training is expensive especially for large and high dimensional datasets. The bottleneck of the SVM training often lies in the kernel value computation. In many real-world problems, the same kernel values are used in many iterations during the training, which makes the caching of kernel values potentially useful. The majority of the existing studies simply adopt the LRU (least recently used) replacement strategy for caching kernel values. However, as we analyze in this paper, the LRU strategy generally achieves high hit ratio near the final stage of the training, but does not work well in the whole training process. Therefore, we propose a new caching strategy called EFU (less frequently used) which replaces the less frequently used kernel values that enhances LFU (least frequently used). Our experimental results show that EFU often has 20\% higher hit ratio than LRU in the training with the Gaussian kernel. To further optimize the strategy, we propose a caching strategy called HCST (hybrid caching for the SVM training), which has a novel mechanism to automatically adapt the better caching strategy in the different stages of the training. We have integrated the caching strategy into ThunderSVM, a recent SVM library on many-core processors. Our experiments show that HCST adaptively achieves high hit ratios with little runtime overhead among different problems including multi-label classification, multiclass classification and regression problems. Compared with other existing caching strategies, HCST achieves 20\% more reduction in training time on average.

description: We show that the g-factor and the spin-flip time T_{1} of a heterojunction quantum dot is very sensitive to the band-bending interface electric field even in the absence of wave function penetration into the barrier. When this electric field is of the order of 10^{5} V/cm, g and T_{1} show high sensitivity to dot radius and magnetic field arising from the interplay between Rashba and Dresselhaus spin-orbit interactions. This result opens new possibilities for the design of a quantum dot spin quantum computer where g-factor and T_{1} can be engineered by manipulating the spin-orbit coupling through external gates.

description: The role of recommendation algorithms in online user confinement is at the heart of a fast-growing literature. Recent empirical studies generally suggest that filter bubbles may principally be observed in the case of explicit recommendation (based on user-declared preferences) rather than implicit recommendation (based on user activity). We focus on YouTube which has become a major online content provider but where confinement has until now been little-studied in a systematic manner. Starting from a diverse number of seed videos, we first describe the properties of the sets of suggested videos in order to design a sound exploration protocol able to capture latent recommendation graphs recursively induced by these suggestions. These graphs form the background of potential user navigations along non-personalized recommendations. From there, be it in topological, topical or temporal terms, we show that the landscape of what we call mean-field YouTube recommendations is often prone to confinement dynamics. Moreover, the most confined recommendation graphs i.e., potential bubbles, seem to be organized around sets of videos that garner the highest audience and thus plausibly viewing time.

description: Magnetic, transport, and x-ray diffraction measurements of ferromagnetic shape memory alloy Ni$_{2.16}$Mn$_{0.84}$Ga revealed that this alloy undergoes an intermartensitic transition upon cooling, whereas no such a transition is observed upon subsequent heating. The difference in the modulation of the martensite forming upon cooling from the high-temperature austenitic state [5-layered (5M) martensite], and the martensite forming upon the intermartensitic transition [7-layered (7M) martensite] strongly affects the magnetic and transport properties of the alloy and results in a large thermal hysteresis of the resistivity $ρ$ and magnetization $M$. The intermartensitic transition has an especially marked influence on the transport properties, as is evident from a large difference in the resistivity of the 5M and 7M martensite, $(ρ_{\mathrm{5M}} - ρ_{\mathrm{7M}})/ρ_{\mathrm{5M}} \approx 15%$, which is larger than the jump of resistivity at the martensitic transition from the cubic austenitic phase to the monoclinic 5M martensitic phase. We assume that this significant difference in $ρ$ between the martensitic phases is accounted for by nesting features of the Fermi surface. It is also suggested that the nesting hypothesis can explain the uncommon behavior of the resistivity at the martensitic transition, observed in stoichiometric and near-stoichiometric Ni-Mn-Ga alloys.

description: A comparative examination of the two major exporters' dynamic wheat acreage response models reveals that U.S. farmers have responded more .sensitively than their Canadian counterparts to government programs but less sensitively to price. This results from differences in the method of government intervention and possibilities for crop substitution. Direct control on acreage characterizes the U.S. approach,. while the Canadian approach is one_ of guaranteeing minimum returns and volumes marketed through the Canadian Wheat Board. In addition, more alternative crops are available for substitution in Canada than in the U.S.

description: DSSR (Dissecting the Spatial Structure of RNA) is a versatile computational tool for the analysis, annotation, modeling, and schematic of RNA/DNA structures, including G-quadruplexes (http://docs.x3dna.org/dssr-overview/). It is built on the widely used 3DNA (3D Nucleic Acids) suite of programs but goes far beyond it in terms of capabilities, usability, and documentation. All DSSR functionalities are integrated into a single executable application (x3dna-dssr) that is just 2MB in size, has no runtime dependencies on third-party libraries, and can be readily incorporated into other bioinformatics resources and research pipelines. DSSR excels in structural bioinformatics of nucleic acids, including RNA, DNA, and their protein complexes. In this webinar, I’ll give an overview of the main features of DSSR.

description: Additional file 2: Table S2 Retroviral-related Pol polyproteins identified in Yarrowia-like yeast genomes. We identified a total of 15 genes that are annotated as retrovirus-related Pol polyproteins within the genome of the five YLYs analyzed. The proteins belong to three different categories which are ‘Line-1’, ‘transposon 297’ and ‘opus’. While the clade II genomes of Y. strains B02, F05 and H10 do only encode for one such protein per genome, genomes of the clade I genomes of Y. strains C11 and E02 encode for several retrovirus-related Pol polyproteins. Thereby, it has to be noted that the type ‘opus’ is only present in the genome of strain E02 and that all respective genes belong to the set of singleton genes (*) of E02.

description: This paper introduces a waveform design method using Multi-Tone Feedback Frequency Modulation (MT-FFM), a generalization of the single oscillator feedback FM method developed by [Tomisawa, 1981]. The MT-FFM utilizes a collection of $K$ harmonically related oscillators each governed by a design parameter $z_k$ which are utilized as a discrete set of parameters that may be modified to generate a richer set of modulation functions than in the single oscillator case. The resulting modulation function is represented using a form of Kapteyn series composed of Generalized Bessel Functions. This paper describes the structure of the MT-FFM waveform, derives the Kapteyn series representation of the waveform's modulation function, and demonstrates the design method with a waveform design example.

description: We present a novel perspective to characterize the chiral magnetic and related effects in terms of angular decomposed modes. We find that the vector current and the chirality density are connected through a surprisingly simple relation for all the modes and any mass, which defines the mode decomposed chiral magnetic effect in such a way free from the chiral chemical potential. The mode decomposed formulation is useful also to investigate properties of rotating fermions. For demonstration we give an intuitive account for a nonzero density emerging from a combination of rotation and magnetic field as well as an approach to the chiral vortical effect at finite density.

description: We use data from the T-SAGE instrument on board the MICROSCOPE space mission to search for Lorentz violation in matter-gravity couplings as described by the Lorentz violating Standard-Model Extension (SME) coefficients $(\bar{a}_\text{eff})_μ^w$, where ($μ= T,X,Y,Z$) and ($w = e,p,n$) for the electron, proton and neutron. One of the phenomenological consequences of a non-zero value of those coefficients is that test bodies of different composition fall differently in an external gravitational field. This is similar to "standard" tests of the universality of free fall, but with a specific signature that depends on the orbital velocity and rotation of the Earth. We analyze data from five measurement sessions of MICROSCOPE spread over a year finding no evidence for such a signature, but setting constraints on linear combinations of the SME coefficients that improve on best previous results by one to two orders of magnitude. Additionally, our independent linear combinations are different from previous ones, which increases the diversity of available constraints, paving the way towards a full decorrelation of the individual coefficients.
Resolution and accuracy of resonances in R-matrix cross sections

description: We investigate the effect of resonances in photoionization and recombination cross sections computed using the R-matrix method. Photoionization and recombination rates derived from high-resolution cross sections for oxygen ions are compared with earlier works with less resolution and accuracy, such as in the widely used Opacity Project data. We find significant differences in photoionization rates for O II metastable states, averaged over Planck functions corresponding to ionizing radiation fields, with respect to the intrinsic accuracy of the calculations and improved resolution. Furthermore, for highly charged ions other physical effects are also important. Recombination rate coefficients, averaged over a Maxwellian distribution, are extremely sensitive to the position and resolution of near-threshold resonances, and radiation damping, in (e + O VII) --> O VI + hnu. Surprisingly however, the effect on the monochromatic and the mean Rosseland and Planck bound-free opacities is relatively small, but may be potentially significant.

description: Cosmic ray propagation in the Milky Way and other galaxies is largely diffusive, with mean free path determined primarily by pitch angle scattering from hydromagnetic waves with wavelength of order the cosmic ray gyroradius. In the theory of cosmic ray self confinement, the waves are generated by instabilities driven by the cosmic rays themselves. The dominant instability is due to bulk motion, or streaming, of the cosmic rays, parallel to the background magnetic field B, and transfers cosmic ray momentum and energy to the thermal gas as well as confining the cosmic rays. Classical arguments and recent numerical simulations show that self confinement due to the streaming instability breaks down unless the cosmic ray pressure and thermal gas density gradients parallel to B are aligned, a condition which is unlikely to always be satisfied We investigate an alternative mechanism for cosmic ray self confinement and heating of thermal gas based on pressure anisotropy instability. Although pressure anisotropy is demonstrably less effective than streaming instability as a self confinement and heating mechanism on global scales, it may be important on mesoscales, particularly near sites of cosmic ray injection.

description: An optical package for mounting VCSEL and PIN diodes for transmitting and receiving optical signals has been developed. The diodes couple to the fibers in a commercial MT connector. The package is quite compact with its physical size significantly smaller than that of the MT connector. This design simplifies the testing and assembly of the optical components because the MT connector with the long fibers attached can be remounted with ease while preserving good light coupling efficiency.

description: School inclusion of students with disabilities relies on reasonable adjustments to curriculum and class activities. The Reasonable Adjustments for Inclusive Education (RAIE) was designed to elicit reasonable adjustments from stakeholders in mainstream school inclusion for three contrived students with varied learning needs. We evaluated a scale for rating the quality of elicited reasonable adjustments across five dimensions: Agency, Authenticity, Real Learning, Strengths Based, and Inclusion. A trial (n = 5 participants) led to refinement of the scale, which was tested for inter-rater reliability with data from a randomized controlled trial (RCT) of an intervention to improve the quality of reasonable adjustments. RCT participants (10 parents, 10 educators, nine allied health professionals) provided 596 reasonable adjustments, rated for each dimension by two independent raters (n = 2980 ratings). Overall agreement was 75.3%; intraclass correlation (ICC) was.778. ICCs were moderate-good (.612–.816). Further refinement and testing with multiple raters are recommended.

description: ORNITHOSPILINI BAN & HAN TRIB. NOV.
Type genus: Ornithospila Warren, 1894 (Holloway, 1996: plate 7, figs 217–225 and 315–316; Han & Xue, 2011a: figs 20–22 of plate 18, figs 342–344, 661–663 and 865–866).
Differential features: The wings of the members of Ornithospilini are bright green. The hind tibia of the male is not dilated. The veins Sc+ R 1 are close to the cell at one point, then separate rapidly on the hindwing; CuA 1 and M 3 are separate, and vein 3A is absent. Sternite 3 of the male abdomen lacks setal patches. The socii of the male genitalia are developed and are almost the same length as the uncus as in Hemitheini but sometimes with a basal process. The signum of the female genitalia, if present, is elongate, ovate and scobinate (Holloway, 1996).
Ornithospilini is proposed as a new, currently monobasic tribe that is mainly distributed in the Oriental region. In this study, the Ornithospilini exemplars (two different species of Ornithospila) form a distinct group that occupies a basal position in Geometrinae. Prout (1912) placed Ornithospila in Group IV of the Old World genera and mentioned that it probably derived from Hipparchus (Geometra), but he also stated that the venation and genitalia of the type species agree better with Prasinocyma Warren and the Iodis group (Jodis). Later, Prout (1920 –41) suggested that some species of Ornithospila are somewhat analogous to Aporandria in size, shape and coloration. Although Hausmann (1996) placed Ornithospila in Geometrini, he also referred to features that differentiate it from Geometrini, such as the presence of an uncus and the shorter and slightly sclerotized socii. Holloway (1996) considered Ornithospila as set apart from the rest of the Geometrinae by the condition of the female signum, which is elongate, ovate and scobinate. This opinion is supported here, as Ornithospila is positioned at the base of Geometrinae, and the relationship to Aporandria and Geometrini is not supported.

description: A remarkable consequence of spontaneously breaking the time translational symmetry in a system, is the emergence of time crystals. In periodically driven systems, discrete time crystals (DTC) can be realized which have a periodicity that is n times the driving period. However, all of the experimental observations have been performed for period-doubling and period-tripling discrete time crystals. Novel physics can arise by simulating many-body physics in the time domain, which would require a genuine realisation of the n-tupling DTC. A system of ultra-cold bosonic atoms bouncing resonantly on an oscillating mirror is one of the models that can realise large period DTC. The preparation of DTC demands control in creating the initial distribution of the ultra-cold bosonic atoms along with the mirror frequency. In this work, we demonstrate that such DTC is robust against perturbations to the initial distribution of atoms. We show how Bayesian methods can be used to enhance control in the preparation of the initial state as well as to efficiently calculate the phase diagram for such a model. Moreover, we examine the stability of DTCs by analyzing quantum many-body fluctuations and show that they do not reveal signatures of heating.

description: We present a systematic study of accelerating cosmologies obtained from M/string theory compactifications of hyperbolic spaces with time-varying volume. A set of vacuum solutions where the internal space is a product of hyperbolic manifolds is found to give qualitatively the same accelerating four-dimensional FLRW universe behavior as a single hyperbolic space. We also examine the possibility that our universe is a hyperbolic space and provide exact Milne type solutions, as well as intersecting S-brane solutions. When both the usual 4D spacetime and the m-dimensional internal space are hyperbolic, we find eternally accelerating cosmologies for $m\geq 7$, with and without form field backgrounds. In particular, the effective potential for a magnetic field background in the large 3 dimensions is positive definite with a local minimum and thus enhances the eternally accelerating expansion.

description: The aim of this study is to homogenize the structure and improve the mechanical properties of blanks produced by wire arc additive manufacturing, using a 1.2 mm diameter aluminum-magnesium alloy (AlMg5) wire as the material. Friction stir processing was successfully used to improve the properties of the part. The WAAM process was carried out using a system based on gas metal arc welding. Argon was used as the shielding gas. The results show a 20% increase in tensile strength and hardness and a doubling of elongation compared to a commercial alloy of the same grade.

description: We describe a simple model for the melting and optical properties of a DNA/gold nanoparticle aggregate. The aggregate is modeled as a cluster of gold nanoparticles on a periodic lattice connected by DNA bonds, and the extinction coefficient is computed using the discrete dipole approximation. The optical properties at fixed wavelength change dramatically at the melting transition, which is found to be higher and narrower in temperature for larger particles, and much sharper than that of an isolated DNA link. All these features are in agreement with available experiments.
