description: On 7 May 2012, the Cologne regional court ruled that circumcising young boys was a form of previous bodily harm (körperverletzung). Although both Muslims and Jews circumcise infant boys as a religious practice, the Cologne court found that the child’s “fundamental right to bodily integrity” was more important than the parents’ rights, leaving Mus-lim and Jewish parents under suspicion of causing bodily harm to their children. After heated public discussions and an expedited legal process, legal authorities permitted the ritual circumcision of male children under a new law. However, the German debates on religious diversity are not yet over. On the third anniversary of the Court decision in 2015, thir-ty-five civil society organisations organised a rally in Cologne for “genital autonomy”, calling for a ban on ritual male cir-cumcision. In this article, I will focus on religious diversity, which is undergoing changes through minority and immigrant claims for religious accommodation. Analysing the ongoing controversies of ritual male circumcision in Germany, I ar-gue that this change is best observed with Muslim and Jewish claims for practicing their religion. By using political de-bates, news reports and information provided by lawyers and medical doctors who were involved in the public debate, I show that religious diversity debates are a litmus test for social inclusion: Muslims and Jews, in this context, are both passive subjects of social inclusion policies and active participants in creating a religiously diverse society in Germany.

description: Στην παρούσα μεταπτυχιακή διατριβή θα μελετήσουμε και θα αναπτύξουμε μεθόδους και αλγορίθμους για την περιγραφή του περιβάλλοντος και των κινηματικών χαρακτηριστικών μίας κινούμενης κάμερας. Συγκεκριμένα θα μελετήσουμε αλγορίθμους ταυτόχρονης χαρτογράφησης και εντοπισμού (SLAM), ενώ θα επικεντρωθούμε στην ανάπτυξή τους με την χρήση μιας μόνο κάμερας. Οι μεθοδολογίες που θα παραθέσουμε, απευθύνονται σε συστήματα πραγματικού χρόνου. Το πλεονέκτημα σε αυτά τα συστήματα είναι ότι εξάγουν τα αποτελέσματα που χρειαζόμαστε για την πλοήγησή του οχήματος επαναλαμβανόμενα και σε κάθε στιγμή που τα χρειαζόμαστε. Στην παρούσα διατριβή θα γίνει μια αναφορά στα ήδη υπάρχοντα πειραματικά συστήματα που έχουν υλοποιηθεί και θα προταθούν δυο νέες μέθοδοι που αποσκοπούν στην εκτίμηση του περιβάλλοντος χάρτη και των κινηματικών χαρακτηριστικών του οχήματος. Η πρώτη μέθοδος που θα αναπτύξουμε βασίζεται στην εκτίμησή με την χρήση φίλτρων Kalman , ενώ στη δεύτερη θα επιχειρηθεί εκτίμηση με την μέθοδο των ελαχίστων τετράγωνων.
description: In the current thesis we will study and develop methods and algorithms in order to describe the kinematic characteristics of a camera in motion. Particularly we will study Simultaneous Localisation and Mapping (SLAM) algorithms and we will focus on developing methods using a single camera. All the methods are in real time systems. The advantage of these systems is the rapid result output periodically and every time we need them. In the current thesis we will demonstrate other existing systems and we will develop two new methods in order to estimate the environment’s map and the kinematics of the camera. The first method is based on estimation with non linear Kalman filters (Extended Kalman Filter or EKF). The second method is based on parameter estimation with the least square method.

description: An analysis is presented for the photometric data on comet C/2013 A1 (Siding Spring) from observations at a large heliocentric distance (near 4.1 AU). Comet C/2013 A1 (Siding Spring) displays intense activity despite the relatively large heliocentric distance. The morphology of the comet's coma is analyzed. The following parameters are measured: the color indices V-R, the normalized spectral gradient of the reflectivity of the comet's dust S', and the dust production rate Af\r{ho}. A numerical simulation is performed for the evolution of the comet's orbit after a close encounter with Mars. The most probable values are obtained for the Keplerian orbital elements of the comet over a hundred-year period. The comet's orbit remains nearly parabolic after passing the orbits of all the Solar System planets.

description: We present correlations involving central intensity ratio (CIR) of 52 early type galaxies, including 24 ellipticals and 28 lenticulars, selected from low density environment in the nearby (< 30 Mpc) universe. CIR is found to be negatively and significantly correlated with the mass of the central super massive black hole, central velocity dispersion, absolute B band magnitude, stellar bulge mass and central Mg2 index of the host galaxy. The study proposes the use of CIR as a simple, fast and efficient photometric tool for exploring the co-evolution scenario existing in galaxies.

Constructive and Destructive Interference of Kerker-type Scattering in an Ultra-thin Silicon Huygens Metasurface

description: High refractive index dielectric nanoparticles have provided a new platform for exotic light manipulation through the interference of multipole modes. The Kerker effect is one example of a Huygens source design. Rather than exploiting interference between the electric dipole and magnetic dipole, as in many conventional Huygens source designs, we explore Kerker-type suppressed backward scattering mediated by the dominant electric dipole, toroidal dipole and magnetic quadrupole. These modes are provided by a designed and fabricated CMOS compatible ultra-thin Silicon nanodisk metasurface with a suppressed magnetic dipole contribution, and verified through multipole decomposition. The non-trivial substrate effect is considered using a semi-analytical transfer matrix model. The model successfully predicts the observed reflection dip. By applying a general criterion for constructive and destructive interference, it is shown that while constructive interference occurs between the electric and toroidal dipole contributions, the experimentally observed suppressed backward Kerker-type scattering arises from the destructive interference between backward scattered contributions due to the total electric dipole and the magnetic quadrupole. Our study paves the way towards new types of Huygens sources or metasurface design, such as for peculiar transverse Kerker scattering.
Strong Decays of Charmed Baryons in Heavy Hadron Chiral Perturbation Theory

description: Strong decays of charmed baryons are analyzed in the framework of heavy hadron chiral perturbation theory (HHChPT) in which heavy quark symmetry and chiral symmetry are synthesized. HHChPT works excellently for describing the strong decays of s-wave charmed baryons. For L=1 orbitally excited states, two of the unknown couplings, namely, $h_2$ and $h_{10}$, are determined from the resonant $Λ_c^+ππ$ mode produced in the $Λ_c(2593)$ decay and the width of $Σ_c(2800)$, respectively. Predictions for the strong decays of the p-wave charmed baryon states $Λ_c(2625)$, $Ξ_c(2790)$ and $Ξ_c(2815)$ are presented. Since the decay $Λ_c(2593)^+\toΛ_c^+ππ$ receives non-resonant contributions, our value for $h_2$ is smaller than the previous estimates. We also discuss the first positive-parity excited charmed baryons. We conjecture that the charmed baryon $Λ_c(2880)$ with $J^P=\frac52^+$ is an admixture of $Λ_{c2}(\frac52^+)$ with and $\tildeΛ''_{c3}(\frac52^+)$; both are L=2 orbitally excited states. The potential model suggests $J^P=\frac52^-$ or $\frac32^+$ for $Λ_c(2940)^+$. Measurements of the ratio of $Σ_c^*π/Σ_cπ$ will enable us to discriminate the $J^P$ assignments for $Λ_c(2940)$. We advocate that the $J^P$ quantum numbers of $Ξ_c(2980)$ and $Ξ_c(3077)$ are $\frac12^+$ and $\frac52^+$, respectively. Under this $J^P$ assignment, it is ready to understand why $Ξ_c(2980)$ is broader than $Ξ_c(3077)$.

description: The application of deep learning toward discovery of data-driven models requires careful application of inductive biases to obtain a description of physics which is both accurate and robust. We present here a framework for discovering continuum models from high fidelity molecular simulation data. Our approach applies a neural network parameterization of governing physics in modal space, allowing a characterization of differential operators while providing structure which may be used to impose biases related to symmetry, isotropy, and conservation form. We demonstrate the effectiveness of our framework for a variety of physics, including local and nonlocal diffusion processes and single and multiphase flows. For the flow physics we demonstrate this approach leads to a learned operator that generalizes to system characteristics not included in the training sets, such as variable particle sizes, densities, and concentration.

Implementing a global perspective: the role of teacher-librarians in facilitating curriculum change
Creators: name: Hidber, Teresa P.
Publisher: name: University of British Columbia
Year: 2009

description: The politics of education is such that curricula in our schools are continually changing. In British Columbia, this is especially apparent since the Sullivan Royal Commission on Education released its report in August 1988. The Commission suggested that "a quality curriculum clearly reflects relevance, equity of access, response to diversity, accountability, and achievement" (Sullivan, 1988, p. 79). Consequently, the British Columbia Ministry of Education published several documents to guide teachers in developing, implementing, and assessing curricula, which promotes the development of an educated citizen. As a teacher and a teacher-librarian, I believe that it is my responsibility to help develop students as educated citizens. I also believe that to become educated citizens, students need to develop a global perspective. The purpose of this research was to investigate ways in which teacher-librarians could facilitate the implementation of a global perspective. I expected to gain insight into the ways that reflection and collaboration motivated teacher-librarians to affect curriculum development and implementation. I also expected to create a situation that encouraged teacher-librarians to evolve as leaders in their schools, whether it was as cooperative program planners and teachers, as advocates of teaching for a global perspective, or as forerunners of information technology. My method of investigation was action research. I chose this approach because it was a collaborative process that involved creating a research plan, acting on the plan, reflecting on the information that was collected, and then revising the plan. Furthermore, it allowed for the improvement of our practice as we progressed. During the project, a group of five teacher-librarians, including me, completed two action research cycles where we developed and reflected upon strategies for implementing a global perspective within our separate schools. In conclusion, the teacher-librarians demonstrated a commitment to the project and documented various situations in which they influenced curriculum implementation that reflected facilitating a global perspective. They felt that the action research process provided valuable opportunities for sharing with peers, which generally does not occur because teacher-librarians tend to occupy unique, solitary positions within their schools.

Designing Decision Aids for Digital Service Design Technique Selection
Creators: name: Liu, Xuanhui
Publisher: name: Karlsruhe
Year: 2019

description: Today, people from a multi-disciplinary background are becoming involved in digital service design processes. With the increasing number of digital service design processes in organizations, it is becoming critical to quickly onboard design novices. A huge amount of design techniques is available in digital service design processes. However, too-much-choice makes the selecting process difficult. Thus, selecting appropriate techniques is a challenge, especially for design novices. This dissertation project focuses on providing decision support for design novices to select design techniques in design processes. Several artifacts in the form of different types of classifications and web-based platforms were developed as decision aids seeking to guide novices to select design techniques in digital service design processes. A design science research paradigm was followed, and three design cycles were conducted in the entire dissertation project. Artifacts were developed and evaluated in each design cycle. In design cycle 1, an expert-based taxonomy and a set of novice-based tags were derived. In design cycle 2, the taxonomy and tags were instantiated as decision aids in a web-based platform and evaluated in a lab experiment. The evaluation demonstrated that the expert-based taxonomy outperformed the novice-based tags. In design cycle 3, an extended version of the web-based platform was developed, including a natural language user interface (UI) in combination with the taxonomy to provide selection support for design techniques. The results of the experimental evaluation of cycle 3 demonstrated that novices’ performance using graphical and natural language UI was dependent on decision-making style and duration of use. The work presented in this thesis contributes to the body of knowledge in the field of digital service design. In design cycle 1, the created taxonomy represents a theory for analysis (type I theory). In design cycle 2 and 3, the proposed design principles represent the core of a theory for design and action (type V theory) to guide the design of decision aids for supporting design novices’ selection of design techniques. Besides the theoretical contribution, the developed platform for the selection of design techniques contributes practically to help design novices select design techniques under different design situations.

description: Recent theoretical and experimental research has explored magnetic solitons in binary Bose-Einstein condensates (BECs). Here we demonstrate that such solitons are part of an SO(3) soliton family when embedded within a full three-component spin-1 manifold with spin-rotational symmetry. To showcase this, we have experimentally created a new type of domain wall magnetic soliton (DWMS) obtained by 90 degree rotations, which consist of a boundary between easy-axis and easy-plane polar phases. Collisions between SO(3) solitons are investigated by numerically solving the Gross-Pitaevskii equations, which exhibit novel properties including rotation and dissipation of soliton spin polarization.

description: We evaluate the density of states (DOS) associated with tridiagonal symmetric Hamiltonian matrices and study the effect of perturbation on one of its entries. Analysis is carried out by studying the resulting three-term recursion relation and the corresponding orthogonal polynomials of the first and second kind. We found closed form expressions for the new DOS in terms of the original one when perturbation affects a single diagonal or off-diagonal site or a combination of both. The projected DOS is also calculated numerically and its relation to the average DOS is explored both analytically and numerically.

description: Groups of companies are the most important characteristic in the global economy. Despite of that groups of companies law as an individual part does not exist. The meaning of groups of companies gave for the first time the Seventh Directive for the harmonization of the law of the member states governing the consolidated accounts of groups of companies and in Greek Law the article 42ε § 5 in law 2190/1920. An attempt to adjust the phenomenon of groups of companies was made with Council Directive 94/45/EC of 22 September 1994 on the establishment of a European Works Council or a procedure in Community-scale undertakings and Community-scale groups of undertakings for the purposes of informing and consulting employees. This directive contains a much better definition of groups of companies and gives a rebuttable assumption of control, including simple cases.

description: We experimentally and theoretically investigate the second order nonlinear optical response of metallo-dielectric multilayer structures composed of Ag and Ta2O5 layers, deposited by magnetron sputtering. Second harmonic generation measurements were performed in reflection mode as a function of incidence angle, using femtosecond pulses originating from a Ti:Sapphire laser system tuned at 800 nm. The dependence of the generated signal was investigated as a function of pump intensity and polarization state. Our experimental results show that the conversion efficiency from a periodic metallo-dielectric sample may be enhanced by at least a factor of 30 with respect to the conversion efficiency from a single metal layer, thanks in part to the increased number of active surfaces, pump field localization and penetration inside the metal layers. The conversion efficiency maximum shifts from 70 degrees for the single silver layer down to approximately 55 degrees for the stack. The experimental results are found to be in good agreement with calculations based on coupled Maxwell-Drude oscillators under the action of a nonlinear Lorentz force term.

Ως όρος ευρύτερος, εντάσσει μέσα στη δυναμική του και την εκπαίδευση ενηλίκων. Η αφετηρία (χρονολογική) της ενηλικίωσης παρουσιάζεται προβληματική και ένας από τους παράγοντες που καλείται να βοηθήσει στη διάκριση αυτή είναι η εμπειρία. Η εμπειρία αναλαμβάνει πλέον το ρόλο της ως διαδικασία μάθησης κι έτσι γίνεται λόγος για την εμπειρική μάθηση, η οποία ως κύρια θέση της προβάλλει τη δυνατότητα που έχουμε οι άνθρωποι να μαθαίνουμε από οποιοδήποτε ερέθισμα είχαμε κατά τη διάρκεια της ζωής μας. Θεωρίες μάθησης προσανατολισμένες ή (και) βασιζόμενες στην εμπειρία βοηθούν για τη δημιουργία ενός θεωρητικου υποβάθρου, ενώ προγράμματα, τα οποία έχουν ήδη εφαρμοστεί στην πράξη αποδεικνύουν τη χρησιμότητα της προσέγγισης αυτής. Στην παρούσα εργασία διερευνήθηκε ο ρόλος της εμπειρίας σε προγράμματα γλωσσομάθειας, στα οποία συμμετείχαν ενήλικοι.
description: Continuing education is related to be part of the whole –general- system of education that tends to be radically developed (for the greek reality) the last years (in terms of scientific survey). As ranged terminology (continuing education) is included in the wider term adult education. The chronological starting point of maturity seems to be problematic and one of the factors that is asked to help in that discrimination is experience. Approaching experience and her role as a process of learning, we reach experiential learning, whose main point of view is to make known the human ability to learn from any stimulus we have during our lives. Learning theories orientated or (even) based on experience help us create the theoretical support, while educational programmes that had already been in use approve the usefulness of this specific approach. This scientifical thesis surveyed the important role of experience in learning language programmes, where adults took part.

description: With due consideration of reasonable cosmological assumptions within the limit of the present cosmological scenario, we have analysed a spherically symmetric metric in 5D setting within the framework of Lyra manifold. The model universe is predicted to be a DE model, dominated by vacuum energy. The model represents an oscillating model, each cycle evolving with a big bang and ending at a big crunch, undergoing a series of bounces. The universe is isotropic and undergoes super-exponential expansion. The value of Hubble's parameter is measured to be $H=67.0691$ which is very close to $H_0=67.36\pm0.54kms^{-1}Mpc^{-1}$, the value estimated by the latest Planck 2018 result. A detailed discussion on the cosmological parameters obtained is also presented with graphs.

description: This paper discusses the problem of identifying differentially expressed groups of genes from a microarray experiment. The groups of genes are externally defined, for example, sets of gene pathways derived from biological databases. Our starting point is the interesting Gene Set Enrichment Analysis (GSEA) procedure of Subramanian et al. [Proc. Natl. Acad. Sci. USA 102 (2005) 15545--15550]. We study the problem in some generality and propose two potential improvements to GSEA: the maxmean statistic for summarizing gene-sets, and restandardization for more accurate inferences. We discuss a variety of examples and extensions, including the use of gene-set scores for class predictions. We also describe a new R language package GSA that implements our ideas.

description: We investigate the computability of algebraic closure and definable closure with respect to a collection of formulas. We show that for a computable collection of formulas of quantifier rank at most $n$, in any given computable structure, both algebraic and definable closure with respect to that collection are $Σ^0_{n+2}$ sets. We further show that these bounds are tight.

description: We present a spectroscopic survey of over 3400 potential members in the North America and Pelican nebulae (NAP) using several low-resolution ($R\approx$ 1300-2000) spectrographs: Palomar/Norris, WIYN/HYDRA, Keck/DEIMOS, and MMT/Hectospec. We identify 580 young stars as likely members of the NAP region based on criteria involving infrared excess, Li I 6708 absorption, X-ray emission, parallax, and proper motions. The spectral types of individual spectra are derived by fitting them with templates that are either empirical spectra of pre-main sequence stars, or model atmospheres. The templates are artificially veiled, and a best-fit combination of spectral type and veiling parameter is derived for each star. We use the spectral types with archival photometry to derive $V$-band extinction and stellar luminosity. From the H-R diagram, the median age of the young stars is about 1 Myr, with a luminosity dispersion of $\sim$0.3--0.4 dex. We investigate the photometric variability of the spectroscopic member sample using ZTF data, and conclude that photometric variability, while present, does not significantly contribute to the luminosity dispersion. While larger than the formal errors, the luminosity dispersion is smaller than if veiling were not taken into account in our spectral typing process. The measured ages of stellar kinematic groups, combined with inferred ages for embedded stellar populations revealed by Spitzer, suggests a sequential history of star formation in the NAP region.

description: Apicoectomy remains a popular and reliable method of dealing with inflamatory diseases of periapical tissues. In spite of dentists efforts and patient's interest, sometimes apicoectomy fails to succeed, so as a result to relapse. The aim of this study is to point out the information that will help dentists to study the factors which affect each level of apicoectomy's surgery. Not only based on national bibliography but also according to clinical incidents, which concern apicoectomy surgery, there are a lot of suggestions in order to increase the percentage of fully healing metioning new materials and techniques.
Generalized parton distributions of light nuclei

description: The measurement of nuclear generalized parton distributions (GPDs) in hard exclusive processes, such as deeply virtual Compton Scattering (DVCS), will be one of the main achievements of a new generation of experiments at high luminosity, such as those under way at the Jefferson Laboratory (JLab) with the 12 GeV electron beam and, above all, those planned at the future Electron Ion Collider. The CLAS collaboration at JLab has recently demonstrated the possibility to disentangle the two different channels of nuclear DVCS, the coherent and incoherent ones, a first step towards the measurement of GPDs of nuclei and of bound nucleons, respectively, opening new exciting perspectives in the field. In this scenario, theoretical precise calculations, ultimately realistic, become mandatory. Light nuclei, for which realistic studies are affordable and conventional nuclear effects can be safely estimated, so that possible exotic effects can be exposed, play an important role. The status of the calculation of GPDs for light nuclei will be summarized, in particular for $^3$He and $^4$He, and some updates will be presented. The prospects for the next years, related to the new series of measurements at future facilities, will be addressed.

description: We present a method to distinguish the high harmonics generated in individual half-cycle of the driving laser pulse by mixing a weak ultraviolet pulse, enabling one to observe the cutoff of each half-cycle harmonic. We show that the detail information of the driving laser pulse, including the laser intensity, pulse duration and carrier-envelope phase, can be {\it in situ} retrieved from the harmonic spectrogram. In addition, our results show that this method also distinguishes the half-cycle high harmonics for a pulse longer than 10 fs, suggesting a potential to extend the CEP measurement to the multi-cycle regime.

Με βάση αυτές τις θεωρίες κατασκευάστηκε μια σχάρα ανάλυσης πολιτισμικών στοιχείων η οποία εφαρμόστηκε σε εγχειρίδια αγγλικής και ιταλικής γλώσσας προκειμένου να διαπιστωθεί πόσα και τι είδους πολιτισμικά στοιχεία περιλαμβάνουν
description: The aim of the research presented in this thesis is the analysis of the cultural load of foreing language coursebooks. Existing theories of culture and the ways in which they were implemented in the field of language teaching within the framework of the intercultural, communicative approach were examined for the achievement of this aim. The development of a scale for the analysis of cultural elements was based on these theories. The scale was used for the analysis of english and italian coursebooks to find out the number and the kind of cultural elements that they include

description: Electronic correlations are crucial to the low energy physics of metallic systems with localized $d$ and $f$ states; however, their effect on band insulators and semiconductors is typically negligible. Here, we measure the electronic structure of the half-Heusler compound FeVSb, a band insulator with filled shell configuration of 18 valence electrons per formula unit ($s^2 p^6 d^{10}$). Angle-resolved photoemission spectroscopy (ARPES) reveals a mass renormalization of $m^{*}/m_{bare}= 1.4$, where $m^{*}$ is the measured effective mass and $m_{bare}$ is the mass from density functional theory (DFT) calculations with no added on-site Coulomb repulsion. Our measurements are in quantitative agreement with dynamical mean field theory (DMFT) calculations, highlighting the many-body origin of the mass renormalization. This mass renormalization lies in dramatic contrast to other filled shell intermetallics, including the thermoelectric materials CoTiSb and NiTiSn; and has a similar origin to that in FeSi, where Hund's coupling induced fluctuations across the gap can explain a dynamical self-energy and correlations. Our work calls for a re-thinking of the role of correlations and Hund's coupling in intermetallic band insulators.
The brain near the edge

description: When viewed at a certain coarse grain, the brain seems a relatively small dynamical system composed by a few dozen interacting areas, performing a number of stereotypical behaviors. It is known that, even relatively small dynamical systems can reliably generate robust and flexible behavior if they are possed near a second order phase transition, because of the abundance of metastable states at the critical point. The approach pursued here assumes that some of the most fundamental properties of the functioning brain are possible because it is spontaneously possed at the border of such instability. In this notes we review the motivation, the arguments and recent results as well as the implications of this view of the functioning brain.
