description: Intramedullary nailing of diaphyseal femoral fractures is a commonly used treatment method in dogs because of its biological and biomechanical advantages compared to bone plating. To achieve adequate resistance of the intramedullary nail against torsional and axial compressive forces, additional application of transcortical screws is needed. As these interlocking screws represent a frequent cause of post-operative complications, a new expandable intramedullary nail (EXPN) was developed, which was designed to provide adequate fracture stabilisation without the need for transcortical fixation. The evaluation of the biomechanical properties of the new EXPN with regard to torsional, compressive and bending stability as well as direct comparison to the biomechanical properties of conventional Steinmann (STMN)- and interlocking (ILN) nails was carried out with different biomechanical test arrangements. No significant statistical differences regarding the torsional and bending resistance between the EXPN and ILN group were seen, which indicates that rotatory as well as bending stability of the innovative EXPN is similar to the conventional ILN. Nevertheless, the percentage deviation between the attempted and successfully reached physiological compressive forces was significantly higher (p = 0.045) in the EXPN group compared to the ILN group, which indicates that the compressive stability of the innovative EXPN might be weaker compared to the ILN. In summary, the new EXPN represents an interesting alternative to conventional intramedullary nails. However, in direct comparison to conventional interlocking nails, the EXPN has shown weaknesses in the neutralization of axial compressive forces, which indicates that at least biomechanically the interlocking nail seems advantageous. Further in-vitro and in-vivo investigations are required before clinical use can be recommended. © 2020 Plenert et al.

description: We introduce a self-passivation of single lead (Pb) and oxygen (O) vacancies in the α-PbO compound through formation of a Pb-O vacancy pair. The preferential mechanism for pair formation involves initial development of the single Pb vacancy which, by weakening the covalent bonding, sets up the crystal lattice for an appearance of the O vacancy. Binding of the Pb and O vacancies occurs through the ionization interactions. Since no dangling bonds appear at the Pb-O pair site, this defect has a minor effect on the electronic properties. In such, vacancy self-passivation offers a practical way to improve the transport properties in thermally grown PbO layers.

description: A bound-state field theory approach to muonic hydrogen is set up using a variant of the Furry representation in which the lowest-order Hamiltonian describes a muon in the presence of a point Coulomb field, but the origin of the binding field is taken to be three charged quarks in the proton which are modeled as Dirac particles that move freely within a spherical well. Bound-state field theory techniques are used to evaluate one- and two-photon effects. Particular attention is paid to two-photon exchange diagrams, which include the effect of proton polarizability. In addition the modification of the electromagnetic self energy of the proton by the electric field of the muon is examined. Finally, the model is used to carry out a calculation of the static electric polarizability of the proton.

description: A Lei nº 13.655/2018 incluiu dispositivos na LINDB com o principal objetivo de elevar os níveis de segurança jurídica e de eficiência na criação e aplicação do Direito Público. Tendo em vista as muitas críticas lançadas ao artigo 20 e seu relevante impacto na atuação dos agentes públicos, no presente artigo, avalia-se se as referidas alterações podem traduzir a adoção da teoria do pragmatismo jurídico no Direito brasileiro, bem como sua adequabilidade ao alcance dos objetivos da lei. Para a persecução desse fim, foram adotados como marco teórico os pressupostos da teoria do pragmatismo jurídico de Richard Posner e Neil MacCormick, estruturando-se sobre a vertente jurídico-dogmática, por meio do raciocínio hipotético dedutivo. Foram realizadas análises de conteúdo, avaliando-se a justificativa da proposição da lei e os pressupostos à teoria do pragmatismo jurídico, por meio de levantamento bibliográfico, bem como os estudos que trataram da aplicação de argumentos consequencialistas nas decisões. Conclui-se que o legislador não optou pela adoção da supramencionada teoria e que, ademais, sua utilização não se mostra adequada para atender aos anseios da lei, em especial, os relativos ao alcance da segurança jurídica e da previsibilidade das decisões, dado os inúmeros desafios para a sua aplicação.

description: The growth of electromagnetic ion cyclotron waves (EMIC) due to a ring distribution of Hydrogen ions is examined. Though these distributions are more commonly implicated in the generation of equatorial noise, their potential for exciting EMIC waves is considered here. It is shown that since the ring distribution is non-monotonic in perpendicular velocity, the amplification achieved by this instability is greater than bi-Maxwellian distributions for typical anisotropies, because the waves can maintain resonance over a much longer part of its trajectory. For ring speeds V_R close to the Alfven speed V_A, the growth rate is maximum at parallel propagation but is much larger at oblique angles compared with a bi-Maxwellian, and can have a second peak approximately at kperp c/omegaPH V_R/V_A ~2.3 for ring speeds about the parallel thermal speed. Strong wave gain is achieved for moderate ring speeds V_R~V_A . The analysis suggests that EMIC wave activity should be closely associated with equatorial noise.

description: The spatially-dependent mass Dirac equation is solved exactly for attractive scalar and repulsive vector Coulomb potentials including a tensor interaction potential under the spin and pseudospin (p-spin) symmetric limits by using the Laplace transformation method (LTM). Closed forms of the energy eigenvalue equation and wave functions are obtained for arbitrary spin-orbit quantum number Some numerical results are given too. The effect of the tensor interaction on the bound states is presented. It is shown that the tensor interaction removes the degeneracy between two states in the spin doublets. We also investigate the effects of the spatially-dependent mass on the bound states under the conditions of the spin symmetric limit and in the absence of tensor interaction

description: We discuss Cahn's time cone method modeling phase transformation kinetics. The model equation by the time cone method is an integral equation in the space-time region. First we reduce it to a system of hyperbolic equations, and in the case of odd spatial dimensions, the reduced system is a multiple hyperbolic equation. Next we propose a numerical method for such a hyperbolic system. By means of alternating direction implicit methods, numerical simulations for practical forward problems are implemented with satisfactory accuracy and efficiency. In particular, in the three dimensional case, our numerical method on basis of reduced multiple hyperbolic equation, is fast.

description: In this paper, a novel receiver for Hexagonal Multicarrier Transmission (HMT) system based on the maximizing Signal-to-Interference-plus-Noise Ratio (Max-SINR) criterion is proposed. Theoretical analyses show that there is a timing offset between the prototype pulses of the proposed Max-SINR receiver and the traditional projection receiver. Meanwhile, the timing offset should be matched to the channel scattering factor of the doubly dispersive (DD) channel. The closed form timing offset expressions of the prototype pulse for Max-SINR HMT receiver over DD channel with different channel scattering functions are derived. Simulation results show that the proposed Max-SINR receiver outperforms traditional projection scheme and obtains an approximation to the theoretical upper bound SINR performance. Consistent with the SINR performance improvement, the bit error rate (BER) performance of HMT system has also been further improved by using the proposed Max-SINR receiver. Meanwhile, the SINR performance of the proposed Max-SINR receiver is robust to the channel delay spread estimation errors.

description: We extend our previous SPH parameter study of the effects of photoionization from O-stars on star-forming clouds to include initially unbound clouds. We generate a set of model clouds in the mass range $10^{4}-10^{6}$M$_{\odot}$ with initial virial ratios $E_{\rm kin}/E_{\rm pot}$=2.3, allow them to form stars, and study the impact of the photoionizing radiation produced by the massive stars. We find that, on the 3Myr timescale before supernovae are expected to begin detonating, the fractions of mass expelled by ionizing feedback is a very strong function of the cloud escape velocities. High-mass clouds are largely unaffected dynamically, while lower-mass clouds have large fractions of their gas reserves expelled on this timescale. However, the fractions of stellar mass unbound are modest and significant portions of the unbound stars are so only because the clouds themselves are initially partially unbound. We find that ionization is much more able to create well-cleared bubbles in the unbound clouds, owing to their intrinsic expansion, but that the presence of such bubbles does not necessarily indicate that a given cloud has been strongly influenced by feedback. We also find, in common with the bound clouds from our earlier work, that many of the systems simulated here are highly porous to photons and supernova ejecta, and that most of them will likely survive their first supernova explosions.

description: Lead titanate (PbTiO3) is a classical example of a ferroelectric perovskite oxide illustrating a displacive phase transition accompanied by a softening of a symmetry-breaking mode. The underlying assumption justifying the soft-mode theory is that the crystal is macroscopically sufficiently uniform so that a meaningful free energy function can be formed. In contrast to PbTiO3, experimental studies show that the phase transition behaviour of lead-zirconate-titanate solid solution (PZT) is far more subtle. Most of the studies on the PZT system have been dedicated to ceramic or powder samples, in which case an unambiguous soft-mode study is not possible, as modes with different symmetries appear together. Our Raman scattering study on titanium-rich PZT single crystal shows that the phase transitions in PZT cannot be described by a simple soft-mode theory. In strong contrast to PbTiO3, splitting of transverse E-symmetry modes reveals that there are different locally-ordered regions. The role of crystal defects, random distribution of Ti and Zr at the B-cation site and Pb ions shifted away from their ideal positions, dictates the phase transition mechanism. A statistical model explaining the observed peak splitting and phase transformation to a complex state with spatially varying local order in the vicinity of the morphotropic phase boundary is given.

description: For high-speed quantum key distribution systems, error reconciliation is often the bottleneck affecting system performance. By exchanging common information through a public channel, the identical key can be generated on both communicating sides. However, the necessity to eliminate disclosed bits for security reasons lowers the final key rate. To improve this key rate, the amount of disclosed bits should be minimized. In addition, decreasing the time spent on error reconciliation also improves the key rate. In this paper we introduce a practical method for expeditious error reconciliation implemented in a Field Programmable Gate Array for a discrete variable quantum key distribution system, and illustrate the superiority of this method to other similar algorithms running on a PC. Experimental results demonstrate the rapidity of the proposed protocol.

description: We present new photometric and spectral observations of the newly discovered nova-like eclipsing star 2MASS J01074282+4845188. To obtain a light curve solution we used model of a nova-like star whose emission sources are a white dwarf surrounded by an accretion disk, a secondary star filling its Roche lobe, a hot spot and a hot line. 2MASS J01074282+4845188 shows the deepest permanent eclipse among the known nova-like stars. It is reproduced by covering the very bright accretion disk by the secondary component. The luminosity of the disk is much bigger than that of the rest light sources. The determined high temperature of the disk is typical for that observed during the outbursts of CVs. The primary of 2MASS J01074282+4845188 is one of the hottest white dwarfs in CVs. The temperature of 5090 K of its secondary is also quite high and more appropriate for a long-period SW Sex star. It might be explained by the intense heating from the hot white dwarf and the hot accretion disk of the target. The high mass accretion rate $\dot{M} = 8\times 10^{-9} M_{\sun}$ yr$^{-1}$, the broad and single-peaked H$α$ emission profile, and the presence of an S-wave are sure signs for the SW Sex classification of 2MASS J01074282+4845188. The obtained flat temperature distribution along the disk radius as well as the deviation of the energy distribution from the black-body law are evidence of the non-steady emission of the disk. The close values of the disk temperature and the parameter $α_{g}$ of 2MASS J01074282+4845188 and those of the cataclysmic stars at eruptions might be considered as an additional argument for the permanent active state of nova-like stars.

description: Nowadays, with the emergence and the evolution of new technologies, such as e-business, a large number of companies are connected to Internet, and have proposed web services to trade. Web services as presented, are conceptually limited components to relatively simple functionalities. Generally, a single service does not satisfy the users needs that are more and more complex. Therefore, services must be made able to be composed to offer added value services. In this paper, a web services composition approach, modelled by Objects-Oriented Petri nets, is presented. In his context, an expressive algebra, which successfully solves the web services complex composition problem, is proposed. A java tool that allows automating this approach; based on a definite algebra and a G-nets meta-model, proposed by us, is developed.

description: In dieser Dissertation betrachten wir die Gleichung $$\sigma_k(A^u) = u^{\left(p-\frac{n+2}{n-2}\right)k}, wobei $n\ge 3$ und $ p \in \left(\frac n{n-2} , \frac{n+2}{n-2}\right). Dabei ist $\sigma_k$ das $k$-te elementarsymmetrische Polynom in den Eigenwerten von $A^u$ und $$A^u = -\frac2{n-2} u^{-\frac{n+2}{n-2}}D^2u + \frac{2n}{(n-2)^2} u^{-\frac{2n} n-2}} \nabla u \otimes \nabla u - \frac2{(n-2)^2}u^{-\frac{2n}{n-2}}|\nabla u|^2 I,$$ wobei $\nabla u$ den Gradienten von $u$ und $D^2u$ die Hessesche Matrix bezeichnen. Diese Gleichung ergibt sich in natürlicher Weise aus dem $\sigma_k$-Yamabe-Problem. Für $k=1$ erhalten wir $$-\Delta u =u^p;$$ dies ist einfach eine klassische subkritische semilinear-elliptische Gleichung. Für $1\le k<\frac n2$ zeigen wir, dass eine zulässige Lösung dieser Gleichung mit nicht-hebbarer isolierter Singularität asymptotisch gleich einer radialen Lösung ist. Mit Hilfe einer genauen Analyse der linearisierten Gleichung sind wir dann in der Lage, asymptotische Entwicklungen höherer Ordnung für die Lösungen zu zeigen. Diese Resultate verallgemeinern die früheren bahnbrechenden Arbeiten von Caffarelli, Gidas und Spruck. Als Beiprodukt erhalten wir Schoens Harnack-Ungleichung in Euklidischen Kugeln, das asymptotische Verhalten ganzer Lösungen. Basierend auf dem asymptotischen Verhalten erhalten wir einen weiteren Beweis des Liouville-Satz von Li und Li.

ALD process is investigated to deposit Al2O3 and HfO2 thin films. The film properties are studied and compared to Ion Beam Sputtering (IBS) Al2O3 and HfO2 single layer films. Anti-reflection coatings for 1ω-4ω of Nd: YAG laser are prepared with ALD HfO2/Al2O3 double layers. The anti-reflection coatings are characterized and compared to the coatings prepared by IBS HfO2/Al2O3. Both ALD HfO2 and Al2O3 have thickness with high resolution due to the self-terminating feature. Thin films can be controlled by counting the cycle number. Both ALD films have uniformity >99% in ϕ60 mm area. At 1064 nm, the ALD single layer films show absorption as weak as 3.7 ppm, and similar LIDT compared to the IBS films. Annealing at 300/400 °C promote the LIDT of ALD Al2O3 by 30%, but does not promote that of ALD HfO2. For 1ω-4ω of Nd: YAG laser, the ALD anti-reflection coatings have generally higher LIDT than IBS coatings. The LIDT of the ALD anti-reflection coating is limited by HfO2 film layer. The damage of both ALD single layers and anti-reflection coatings are induced by defects. ALD films, both single layers and multilayers, were found to have severe tensile stress. A model for the origin of the film stress is established. Taking advantage of the high LIDT and opposite stress of ALD and IBS films, a concept is proposed to develop high LIDT and stress compensated coatings with ALD Al2O3 and IBS SiO2. An anti-reflection coating consisting of 4 layers was prepared following this concept. The compensated stress is much smaller than either ALD Al2O3 or IBS SiO2 single layer. The LIDT of the multi-layer is lower than the single layers because of the defects introduced during shift between the ALD and IBS coating chambers. This concept has potential application in high power laser components if a proper coating plant is developed to reduce the defects. ALD films have high density, thus could be used as capping layer against vacuum-air-shift when the environment changes. The capping effect of ALD Al2O3 on evaporated Ta2O5/SiO2 multilayers was studied and discussed. The application of ALD films in nanolaminates and chirped mirror is discussed. The study in this thesis indicates the high versatility of ALD films for applications in high-power coatings.

Ελληνική κουζίνα

description: Η παρούσα εργασία με θέμα τους κρυφούς θησαυρούς της ελληνικής κουζίνας πραγματεύεται την πλούσια διατροφική αξία και απλότητα που χαρακτηρίζει τις ελληνικές καθημερινές συνταγές. Με αφορμή την πτυχιακή μου εργασία είχα την χαρά να ασχοληθώ με θέματα πολύ ενδιαφέροντα για μένα, όπως η διατροφή, η μαγειρική και η φωτογραφία και ήλπιζα να καταφέρω να ρίξω φως σε αυτά τα απλά και πολλές φορές υποτιμημένα πιάτα που στην Ελλάδα ξεχνάμε πόσο διατροφικά και πολιτισμικά σπουδαία είναι και στο εξωτερικό είναι παντελώς άγνωστα. Η πρόταση έκθεσης των φωτογραφιών είναι το περιοδικό μαγειρικής, είτε σε έντυπη είτε σε ηλεκτρονική μορφή. Μέσω των φωτογραφιών οι ξένοι αναγνώστες θα ‘’γνωρίσουν’’ τα πιάτα και μέσω του κειμένου θα ενημερωθούν για αυτά. Αντίστοιχα το ελληνικό κοινό θα θυμηθεί το πλούσιο κόσμο της κουζίνας του τόπου του και ίσως παρακινηθεί να τα εντάσσει συχνότερα στη καθημερινή του διατροφή. Η επιλογή των συνταγών ήταν πολύ συνειδητή και είχε ως πυλώνα την απλότητα και ευκολία εύρεσης των υλικών, την ευκολία και συντομία παρασκευής σε συνδυασμό κυρίως με την πλούσια διατροφική αξία. Η μαγειρική μαρτυρά πολλά για έναν τόπο. Το κλίμα, τα διαθέσιμα υλικά και οι ασχολίες των ανθρώπων είναι κάποια από τα χαρακτηριστικά μίας χώρας άρρηκτα συνδεδεμένα με το φαγητό. Έτσι μέσω συνταγών εύκολων, απλών και υγιεινών το κοινό θα έχει την ευκαιρία να πάρει μία γεύση από τον ελληνικό πολιτισμό και να εμπνευστεί ώστε να τα εντάξει στη ζωή του.

description: The Kuramoto model constitutes a paradigmatic model for the dissipative collective dynamics of coupled oscillators, characterizing in particular the emergence of synchrony. Here we present a classical Hamiltonian (and thus conservative) system with 2N state variables that in its action-angle representation exactly yields Kuramoto dynamics on N-dimensional invariant manifolds. We show that the synchronization transition on a Kuramoto manifold emerges where the transverse Hamiltonian action dynamics becomes unstable. The uncovered Kuramoto dynamics in Hamiltonian systems thus distinctly links dissipative to conservative dynamics.

description: Ο όρος της αθλητικής χορηγίας συνάδει με την οικονομική υποστήριξη ενός αθλητικού οργανισμού από μια επιχείρηση, έναντι του δικαιώματος άσκησης ολοκληρωμένης επικοινωνιακής πολιτικής από την επιχείρηση αυτή στο πλαίσιο των δραστηριοτήτων του οργανισμού. Η αθλητική χορηγία στηρίζεται στην ανταποδοτικότητα και μπορεί να αποτελέσει ένα σημαντικό στρατηγικό μέσο επικοινωνίας, αποτελώντας με αυτόν τον τρόπο την πεμπτουσία του αθλητικού μάρκετινγκ. Αναφορικά με την επιστημονική έρευνα περί της αθλητικής χορηγίας, οι δύο τελευταίες δεκαετίες ανέδειξαν σαφείς προόδους και στο κομμάτι της αξιολόγησης των επιδράσεων της χορηγίας, καθώς και της στρατηγικής διαχείρισης χορηγιών, ενώ υπήρξε μια αξιοσημείωτη στροφή προς την καλύτερη κατανόηση του τρόπου με τον οποίο η χορηγία γίνεται αντιληπτή από τον τελικό καταναλωτή. Υπάρχουν, αντιθέτως, τομείς και στόχοι της χορηγίας, οι οποίοι παραμελήθηκαν ερευνητικά, όπως η λειτουργική υπαγωγή μιας αθλητικής χορηγίας εντός των εταιρειών ή οι διαδικασίες προϋπολογισμού χορηγιών Μάλιστα, σύμφωνα με τους Cornwellκαι Maigan (1998), υπάρχουν πέντε βασικές ερευνητικές κατευθύνσεις-άξονες που επισκοπούν την εξέλιξη της έρευνας για την αθλητική χορηγία και αυτές οι κατευθύνσεις αναφέρονται στη φύση της χορηγίας, τις πτυχές διαχείρισής της, τη μέτρηση των αποτελεσμάτων της χορηγίας, τη στρατηγική χρήση της, αλλά και τις νομικές και ηθικές εκτιμήσεις αναφορικά με τη χορηγία. Στόχος, επομένως, της έρευνας ήταν να δημιουργηθεί, μέσω μιας εκτεταμένης βιβλιογραφικής ανασκόπησης, η ομαδοποίηση των μελετών και ερευνών περί αθλητικής χορηγίας στη βάση της κατηγοριοποίησης που εφάρμοσαν οι Cornwellκαι Maigan (1998), η οποία είχε ως απότοκο την εξαγωγή συμπερασμάτων για τα ερευνητικά τεκταινόμενα σχετικά με την αθλητική χορηγία, καθώς και προτάσεων αναφορικά με το που πρέπει να κινηθεί η αθλητική χορηγία στο απώτερο μέλλον.

description: A mean field model is presented for the configuration dependent effective demagnetizing and anisotropy fields in assemblies of exchange decoupled magnetic particles of arbitrary shape which are expressed in terms of the demagnetizing factors of the particles and the volumetric shape containing the assembly. Perpendicularly magnetized 2D assemblies have been considered, for which it is shown that the demagnetizing field is lower than the continuous thin film. As an example of these 2D systems, arrays of bistable cylindrical nanowires have been characterized by remanence curves as well as ferromagnetic resonance, which have served to show the correspondence of these measurements with the model and also to validate the mean field approach. Linear chains of cylinders and spheres have been analyzed leading to simple expressions to describe the easy axis rotation induced by the interaction field in chains of low aspect ratio cylindrical particles, and the dipolar magnetic anisotropy observed in the linear chain of spheres. These examples serve to underline the dependence on the dipolar interaction field and effective demagnetizing factor on the contributions that arise from the shape of the outer volume.

description: Racial discrimination – the unjust or prejudicial treatment of a person or a group of people based on racial group membership – is a harmful stressor on Black families and occurs across many contexts, including workplaces, schools, and neighborhoods. Black parents try to lessen the negative effects of racial discrimination by communicating racial socialization messages through which they tell their children about their race, racial group membership (cultural socialization), and interracial interactions (preparation for bias). In this brief, PRC graduate student trainee Loraine Scott and PRC faculty scholar Fatima Varner test how the racial composition of Black families’ contexts interact with experiences of racial discrimination to shape parents’ racial socialization messages to their adolescents. They found that more personal experiences of racial discrimination and working with more Black people was associated with more cultural socialization messages. Adolescents’ and parents' experiences with racial discrimination were associated with more preparation for bias messages. In addition, parents with few Black co-workers gave more preparation for bias messages when they had more personal racial discrimination experiences. To lessen experiences of racial discrimination for Black workers and other workers from marginalized communities, the authors advocate for strengthening policies related to diversity, equity, and inclusion.

description: Non-radiative energy transfer between a Rydberg atom and a polar molecule can be controlled by a static electric field. Here, we show how to exploit this control for state-resolved, non-destructive detection and spectroscopy of the molecules, where the lineshape reflects the type of molecular transition. Using the example of ammonia, we identify the conditions for collision-mediated spectroscopy in terms of the required electric field strengths, relative velocities, and molecular densities. Rydberg atom-enabled spectroscopy is feasible with current experimental technology, providing a versatile detection method as a basic building block for applications of polar molecules in quantum technologies and chemical reaction studies.
