description: Ο σκοπός της διατριβής ήταν ο χαρακτηρισμός των λεμφοκυτταρικών υποπληθυσμών και των MHC-II+ κυττάρων του φλεγμονικού διηθήματος στις αλλοιώσεις της αποφολιδωτικής δερματίτιδας(ΑΔ) στη συμπτωματική λεισμανίωση του σκύλου(ΛΣ) σε συνδυασμό με την παρουσία παράσιτων και σμηγματαδενίτιδας στο χορίο του δέρματος. Βιοψίες δέρματος από σκύλους με αλλοιώσεις ΑΔ(ομάδα Α) συγκρίθηκαν με φυσιολογικής όψης δέρμα από τα ίδια ζώα(ομάδα Β), φυσιολογικής όψης δέρμα από σκύλους με ΛΣ χωρίς ΑΔ(ομάδα Γ) και υγιείς μάρτυρες(ομάδα Δ). Εγινε καταγραφή των ιστοπαθολογικών αλλοιώσεων και ανοσοϊστοχημική χρώση των CD3+, CD45RA+, CD4+, CD8α+, CD8β+, CD21+, MHC-II+ κυττάρων και των αμαστίγωτων μορφών της λεϊσμανίας που καταμετρήθηκαν με το σύστημα ανάλυσης της εικόνας. Η ομάδα Α χαρακτηρίζεται ιστοπαθολογικά από (πυο)κοκκιωματώση δερματίτιδα με ή χωρίς σμηγματαδενίτιδα και ανοσοιστοχημικά από αυξημένο αριθμό διηθούντων CD3+ κυττάρων και μικρότερο CD21+ κυττάρων στο χορίο, υπεροχή των CD8+ σε σχέση με τα CD4+ κύτταρα (εκτος των περιοχών με σμηγματαδενίτιδα) και έντονη έκφραση του MHC-II τόσο από τα επιδερμικά όσο και από τα κύτταρα του χορίου. Παρόμοια(αν και λιγότερο έντονα) ευρήματα παρατηρήθηκαν στις ομάδες Β και Γ
description: The purpose of this study was to chapacterize the lymphocyte subsets and MHC-II expressing cells of the inflammatory infiltrate in exfoliative dermatitis lesions(ED) in spontaneous canine leishmaniosis(CL) along with the presence of parasites from dogs with CL and ED lesions(Group A) were compared with normal-looking skin of the same animals(group B), normal-looking skin from dogs with CL without ED(goup C) and normal controls(group D). Apart from histopathological lesions recording, CD3+, CD45RA+, CD4+, CD8a+, CD8b+, CD21+, MHC-II+ cells and leishmania amastigotes were immunohistochemically stained and counted by using an image analysis system. Group A is characterized pathologically by (pyo)granulomatous dermatitis with or without sebaceous adenitis and immunohistochemically by icreased numbers of CD3+ cells and lower of C021+ cells in the dermis, a predominance of CD8+ over CD4+ cells(except in areas with sebaceous adenitis) and a strong expression of MHC-II by both dermal and epidermal cells, similar(although less pronounced) finding are present in groups B and C

description: A new technique to detect protoplanets is by observing the kinematics of the surrounding gas. Gravitational perturbations from a planet produce peculiar `kinks' in channel maps of different gas species. In this paper, we show that such kinks can be reproduced using semi-analytic models for the velocity perturbation induced by a planet. In doing so we i) confirm that the observed kinks are consistent with the planet-induced wake; ii) show how to quantify the planet mass from the kink amplitude; in particular, we show that the kink amplitude scales with the square root of the planet mass for channels far from the planet velocity, steepening to linear as the channels approach the planet; iii) show how to extend the theory to include the effect of damping, which may be needed in order to have localized kinks.

Εγινε η συνοπτική κατάταξη των ημερών σε τέσσερις βασικές ισοβαρικές στάθμες. Μελετήθηκε η κατανομή των καταστάσεων αυτών. Επίσης μελετήθηκε μια σειρά μετεωρολογικών παραμέτρων. Αυτές είναι είτε δυναμικές-συνοπτικές ή μέσης κλίμακας-είτε μικροφυσικές. Εντοπίστηκαν αυτές που παρουσιάζουν τη μεγαλύτερη διακριτική ικανότητα μεταξύ των ημερών χαλαζόπτωσης και σχετικής ευστάθειας τόσο στο σύνολο τηε θερμής περιόδου όσο και κατά μήνα και κατά συνοπτική κατάσταση. Προσδιορίστηκαν τιμές αυτών που συνδέονται με αυξημένη πιθανότητα χαλαζόπτωσης. Από τη μελέτη, αναδείχθηκε ο ρόλος των μέσων και ανωτέρων, κυρίως, στρωμάτων της τροπόσφαιρας σε ένα φαινόμενο που έχει έντονο τοπικό χαρακτήρα
description: In the present study the hailstorms that occured in Northern Greece(North-Central Macedonia) during the warm period of the years 1984-2000 were studied. The hailstorm days were classified according to the prevailing synoptic situation in four isobaric levels. The distribution of the synoptic situation at these level, was studied. Additionally, a series of meteorological parameters were studied. Those parameters are either dynamical-of synoptic or meso-scale - either microphysical parameters. Among them, the ones that contribute to the best identification between hailstorm days and relatively stable days were identified, and they were studied by mont and synoptic situation, the role of various parameters at certain levels was pointed out, especially at higher levels
Exact magnetization plateaus and phase transitions in spin-S Heisenberg antiferromagnets in arbitrary dimensions

description: We generalize a class of Heisenberg antiferromagnets in one, two and three dimensions, which have been shown to exhibit magnetization plateaus for spin-1/2. In a certain parameter range of the general model, which is formally defined in D dimensions, we obtain the exact ground state(s) in the presence of an external magnetic field for arbitrary values of spin. In this range, the magnetization remains a constant as a function of the external field, except at some special values of the field where there is a jump from one plateau to the next. The plateaus are formed at certain specific fractions of the full magnetization which are determined by the spin and the lattice. Our general spin-S result reproduces the known cases for spin-1/2 in various lattices. Furthermore, we argue that outside the exact regime, the mechanism for the plateau formation is different. This results in first order phase transitions along some of the plateaus as the coupling constant is varied. We rigorously show the existence of such transitions for some particular cases. Finally, we numerically analyze a spin-1 model in one dimension using exact diagonalization to obtain its complete phase diagram. It agrees with our analytic results.

description: Currently many different modeling languages are used for workflow definitions in BPM systems. Authors of this paper analyze the two most popular graphical languages, with highest possibility of wide practical usage - UML Activity diagrams (AD) and Business Process Modeling Notation (BPMN). The necessary in practice workflow aspects are briefly discussed, and on this basis a natural AD profile is proposed, which covers all of them. A functionally equivalent BPMN subset is also selected. The semantics of both languages in the context of process execution (namely, mapping to BPEL) is also analyzed in the paper. By analyzing AD and BPMN metamodels, authors conclude that an exact transformation from AD to BPMN is not trivial even for the selected subset, though these languages are considered to be similar. Authors show how this transformation could be defined in the MOLA transformation language.

description: The Security Council of the United Nations is a political organ vested with wide powers and subject to few limitations when acting under Chapter VII of the UN Chapter. The purposes and principles of the United Nations Constitute its limitations such as, in particular the right of peoples to self-determination, the fundamental rules of human rights, the rules of international humanitation law and the territorial integrity of states. However, there is no established procedure of direct judicial control of the Security Council action in the UN system. Judicial control by th ICJ is only possible either through its advisory jurisdiction or indirectly and incidentally in contentions cases albeit with poor results. Such judicial control is, therefore, not a sufficient instrument to present or redress instances of illegal Security Council action

In particular, we display the class of space-times that possess this property and demonstrate how these congruences can be found. A special case within this class are the Robinson- Trautman space-times. In addition, we show that in each case the congruence is isolated in the sense that there are no other neighboring congruences with this dual property.

description: The contemporary restructuring of religion and secularism demands a departure from conventional post-secular analyses that remain confined within the epistemic and institutional frameworks of the nation-state. This paper develops the concept of post-secular cosmopolitanization to theorize the dissolution of the secular–religious binary as a regulatory mechanism of power, revealing how religion and secularism are co-constituted through global entanglements that transcend national boundaries. Unlike dominant conceptions of post-secularism, which assumes the continued dominance of secular and national institutions despite religious resurgence, post-secular cosmopolitanization captures the ways in which transnational religious movements, digital religious networks, and global governance structures are reshaping religious authority, secular regulation, and political sovereignty. It is shown that this transformation leads to three major consequences: (1) the erosion of the nation-state’s regulatory monopoly over religious life as alternative religious and transnational actors emerge as influential governance entities; (2) the deterritorialization and fragmentation of religious authority, undermining traditional clerical and institutional hierarchies; and (3) the blurring of religious and secular domains, where global economic, legal, and political structures increasingly integrate religious actors, norms, and ethical frameworks. These developments signal a paradigmatic shift beyond the secularization thesis and dominant conceptions of post-secularism, necessitating a reconsideration of how power, governance, and religious authority function in a world no longer structured by the nation-state’s exclusive claim to sovereignty. By analyzing these entanglements, this paper provides a theoretical framework to understand the reconfiguration of global secular and religious orders, challenging entrenched assumptions about the trajectory of modernity.

description: The coupling between the angular momentum of a compact object and an external tidal field gives rise to the "rotational" tidal Love numbers, which affect the tidal deformability of a spinning self-gravitating body and enter the gravitational waveform of a binary inspiral at high post-Newtonian order. We provide numerical evidence for a surprising "hidden" symmetry among the rotational tidal Love numbers with opposite parities, which are associated to perturbations belonging to separate sectors. This symmetry, whose existence had been suggested on the basis of a Lagrangian description of the tidal interaction in a binary system, holds independently of the equation of state of the star.

description: Applications of algebras in physics are related to the connection of measurable observables to relevant elements of the algebras, usually the generators. However, in the determination of the generators in Lie algebras there is place for some arbitrary conventions. The situation is much more involved in the context of quantum algebras, where inside the quantum universal enveloping algebra, we have not enough primitive elements that allow for a privileged set of generators and all basic sets are equivalent. In this paper we discuss how the Drinfeld double structure underlying every simple Lie bialgebra characterizes uniquely a particular basis without any freedom, completing the Cartan program on simple algebras. By means of a perturbative construction, a distinguished deformed basis (we call it the analytical basis) is obtained for every quantum group as the analytical prolongation of the above defined Lie basis of the corresponding Lie bialgebra. It turns out that the whole construction is unique, so to each quantum universal enveloping algebra is associated one and only one bialgebra. In this way the problem of the classification of quantum algebras is moved to the classification of bialgebras. In order to make this procedure more clear, we discuss in detail the simple cases of su(2) and su_q(2).

description: Renormalization Group (RG) techniques have been successfully employed in quantum field theory and statistical physics. Here we apply RG methods to study the non-linear stages of structure formation in the Universe. Exact equations for the power spectrum, the bispectrum, and all higher order correlation functions can be derived for any underlying cosmological model. A remarkable feature of the RG flow is the emergence of an intrinsic UV cutoff, due to dark matter velocity dispersion, which improves the convergence of the equations at small scales. As a consequence, the method is able to follow the non-linear evolution of the power-spectrum down to zero redshift and to length-scales where perturbation theory fails. Our predictions accurately fit the results of $N$-body simulations in reproducing the ``Baryon Acoustic Oscillations'' features of the power-spectrum, which will be accurately measured in future galaxy surveys and will provide a probe to distinguish among different dark energy models.

description: As quantum computing approaches its first commercial implementations, quantum simulation emerges as a potentially ground-breaking technology for several domains, including Biology and Chemistry. However, taking advantage of quantum algorithms in Quantum Chemistry raises a number of theoretical and practical challenges at different levels, from the conception to its actual execution. We go through such challenges in a case study of a quantum simulation for the hydrogen (H2) and lithium hydride (LiH) molecules, at an actual commercially available quantum computer, the IBM Q. The former molecule has always been a playground for testing approximate calculation methods in Quantum Chemistry, while the latter is just a little bit more complex, lacking the mirror symmetry of the former. Using the Variational Quantum Eigensolver (VQE) method, we study the molecule's ground state energy versus interatomic distance, under the action of stationary electric fields (Stark effect). Additionally, we review the necessary calculations of the matrix elements of the second quantization Hamiltonian encompassing the extra terms concerning the action of electric fields, using STO-LG type atomic orbitals to build the minimal basis sets.

description: Most metallo-supramolecular assemblies of low nuclearity adopt simple topologies, with bridging ligands spanning neighboring metal centers in a direct fashion. Here we contribute a new structural motif to the family of host compounds with low metal count (two) that consists of a pair of doubly-interlocked, figure-eight-shaped subunits, also termed “lemniscates”. Each metal is chelated by two chiral bidentate ligands, composed of a peptidic macrocycle that resembles a natural product with two pyridyl-terminated arms. DFT calculation results suggest that dimerization of the mononuclear halves is driven by a combination of 1) Coulomb interaction with a central anion, 2) π-stacking between intertwined ligand arms and 3) dispersive interactions between the structure’s compact inner core bedded into an outer shell composed of the cavitand-type macrocycles. The resulting cage-like architecture was characterized by NMR, MS and X-ray structure analyses. This new mechanically bonded system highlights the scope of structural variety accessible in metal-mediated self-assemblies composed of only a few constituents.

description: During plastic deformation of crystalline materials, point defects such as vacancies and interstitials are generated by jogs on moving dislocations. A detailed model for jog formation and transport during plastic deformation was developed within the vector density-based continuum dislocation dynamics framework (Lin and El-Azab, 2020; Xia and El-Azab, 2015). As a part of this model, point defect generation associated with jog transport was formulated in terms of the volume change due to the non-conservative motion of jogs. Balance equations for the vacancies and interstitials including their rate of generation due to jog transport were also formulated. A two-way coupling between point defects and dislocation dynamics was then completed by including the stress contributed by the eigen-strain of point defects. A jog drag stress was further introduced into the mobility law of dislocations to account for the energy dissipation during point defects generation. A number of test problems and a fully coupled simulation of dislocation dynamics and point defect generation and diffusion were performed. The results show that there is an asymmetry of vacancy and interstitial generation due to the different formation energies of the two types of defects. The results also show that a higher hardening rate and a higher dislocation density are obtained when the point defect generation mechanism is coupled to dislocation dynamics.
Phase equivalent potentials, Complex coordinates and Supersymmetric Quantum Mechanics

description: Supersymmetric Quantum Mechanics may be used to construct reflectionless potentials and phase-equivalent potentials. The exactly solvable case of the $λsech^2$ potential is used to show that for certain values of the strength $λ$ the phase-equivalent singular potential arising from the elimination of all the boundstates is identical to the original potential evaluated at a point shifted in the complex cordinate space. This equivalence has the consequence that certain general relations valid for reflectionless potentials and phase-equivalent potentials lead to hitherto unknown identities satisfied by the Associated Legendre functions. This exactly solvable probelm is used to demonstrate some aspects of scattering theory.

description: We show that if there exists a special kind of Born-Infeld type scalar field, then one can send information from inside a black hole. This information is encoded in perturbations of the field propagating in non-trivial scalar field backgrounds, which serves as a "new ether". Although the theory is Lorentz-invariant it allows, nevertheless, the superluminal propagation of perturbations with respect to the "new ether". We found the stationary solution for background, which describes the accretion of the scalar field onto a black hole. Examining the propagation of small perturbations around this solution we show the signals emitted inside the horizon can reach an observer located outside the black hole. We discuss possible physical consequences of this result.

Modelling of Interfacial Flows Based on An Explicit Volume Diffusion Concept

description: A novel volume of fluid model (VoF) called explicit volume diffusion (EVD) is developed for the simulation of interfacial flows, including those with turbulence and primary spray atomisation. The EVD model is derived by volume averaging the VoF equations over a physically-defined length scale. This introduces unclosed sub-volume flux, sub-volume stress and volume averaged surface tension force. Sub-volume fluctuations arise due to both turbulent motions and other interface dynamics which can, in general, occur in both laminar and turbulent flows. Both of these types of fluctuations are attenuated by the volume averaging process. The sub-volume flux is closed by a gradient diffusion model and involves an explicit volume diffusion coefficient that is linked to the physical length scale. The sub-volume stress closure introduces an explicit volume viscosity augmented by turbulent viscosity in turbulent flows. The volume averaged surface tension force closure is based on fractal properties of wrinkled sub-volume interfaces. These closures are evaluated through a priori analysis of resolved flow simulations for a series of two-dimensional laminar and three-dimensional turbulent interfacial shear flows. Subsequently, full EVD simulations are validated for these shear flows and for a laboratory airblast spray jet. Numerical convergence is demonstrated by keeping the physical length scale constant while reducing the numerical grid size so that numerical diffusion diminishes and becomes overwhelmed by the explicit volume diffusion. A sensitivity analysis is also conducted for variations in the physical length scale, which is compared to the boundary layer thickness on the light fluid side of the interface.
Thermally assisted Pauli spin blockade in double quantum dots

description: We investigate the influence of thermal energy on the current flow and electron spin states in double quantum dots in series. The quadruplet Pauli spin blockade, which is caused by the quadruplet and doublet states, occurs at low temperatures affecting the transport properties. As the temperature increases, the quadruplet Pauli spin blockade occurs as a result of the thermal energy, even in regions where it does not occur at low temperatures. This is because the triplet state is formed in one dot as a result of the gradual change of the Fermi distribution function of the electrodes with increasing temperature. Moreover, the thermally assisted Pauli spin blockade results in coexistence of the Coulomb and Pauli spin blockades. Conversely, for the standard triplet Pauli spin blockade, which occurs as a result of the triplet and singlet states, the current through the double dots monotonously smears out as the temperature increases. Therefore, the thermally assisted Pauli spin blockade is not clearly observed. However, the coexistence of the Coulomb and triplet Pauli spin blockades as a result of the thermal energy is clearly obtained in the calculation of the probability of the spin state in the double dots.

description: Disk material has been observed around both components of some young close binary star systems. It has been shown that if planets form at the right places within such disks, they can remain dynamically stable for very long times. Herein, we numerically simulate the late stages of terrestrial planet growth in circumbinary disks around 'close' binary star systems with stellar separations between 0.05 AU and 0.4 AU and binary eccentricities up to 0.8. In each simulation, the sum of the masses of the two stars is 1 solar mass, and giant planets are included. Our results are statistically compared to a set of planet formation simulations in the Sun-Jupiter-Saturn system that begin with essentially the same initial disk of protoplanets. The planetary systems formed around binaries with apastron distances less than ~ 0.2 AU are very similar to those around single stars, whereas those with larger maximum separations tend to be sparcer, with fewer planets, especially interior to 1 AU. We also provide formulae that can be used to scale results of planetary accretion simulations to various systems with different total stellar mass, disk sizes, and planetesimal masses and densities.

On the nonlinear dynamics of a space platform based mobile flexible manipulator
Creators: name: Mah, Harry Wayne
Publisher: name: University of British Columbia
Year: 2008

description: The thesis aims at development of a rather versatile tool for studying dynamics and control of an orbiting flexible manipulator. It is motivated by the Canadian contribution, in the form of the Mobile Servicing System (MSS), to the U.S. led Space Station (Freedom) program, scheduled to be operational by the turn of the century. To begin, a relatively general dynamical formulation is developed for a large class of systems characterized by interconnected beam and/or rigid articulating members forming a chain-type geometry. As can be expected, the governing nonlinear, nonautonomous and coupled equations of motion, extremely long even in matrix notation, are not amenable to any known closed form solution. Hence the attention is focused towards development of an efficient numerical code, in a modular format to help assess relative importance of the various system parameters. Validity of the formulation and the computer code are assessed and their operational aspects demonstrated through a parametric response analysis. Emphasis throughout is on methodology and general approach leading to understanding of the multibody dynamics problem at the fundamental level.
New Photometry and Spectra of AB Doradus C: An Accurate Mass Determination of a Young Low-Mass Object with Theoretical Evolutionary Tracks

description: We present new photometric and spectroscopic measurements for the unique, young, low-mass evolutionary track calibrator AB Dor C. While the new Ks photometry is similar to that previously published in Close et al. (2005) the spectral type is found to be earlier. Based on new H & K IFS spectra of AB Dor C (Thatte et al. 2007; paper 1) we adopt a spectral type of M5.5+/-1.0 for AB Dor C. This is considerably earlier than the M8+/-1 estimated in Close et al. (2005) and Nielsen et al. (2005) yet is consistent with the M6+/-1 independently derived by Luhman & Potter (2005). However, the spectrum presented in paper 1 and analyzed here is a significant improvement over any previous spectrum of AB Dor C. We also present new astrometry for the system which further supports a 0.090+/-0.005 Msun mass for the system. Once armed with an accurate spectrum and Ks flux we find L=0.0021+/-0.0005 Lsun and Teff=2925{+170}{-145}K for AB Dor C. These values are consistent with a ~75 Myr 0.090+/-0.005 Msun object like AB Dor C according to the DUSTY evolutionary tracks (Chabrier et al. 2000). Hence masses can be estimated from the HR diagram with the DUSTY tracks for young low-mass objects like AB Dor C. However, we cautiously note that underestimates of the mass from the tracks can occur if one lacks a proper (continuum preserved) spectra or is relying on NIR fluxes alone.

Improvement of quark propagator estimation through domain decomposition

description: Applying domain decomposition to the lattice Dirac operator and the associated quark propagator, we arrive at expressions which, with the proper insertion of random sources therein, can provide improvement to the estimation of the propagator. Schemes are considered for both open and closed (or loop) propagators. In the end, our technique for improving open contributions is similar to the ``maximal variance reduction'' approach of Michael and Peisa, but contains the advantage, especially for improved actions, of dealing directly with the Dirac operator. Using these improved open propagators for the Chirally Improved operator, we present preliminary results for the static-light meson spectrum.

description: Motivated by recent experiments on the phonon contribution to the thermal Hall effect in the cuprates, we present an analysis of chiral phonon transport. We assume the chiral behavior arises from a non-zero phonon Hall vicosity, which is likely induced by the coupling to electrons. Phonons with a non-zero phonon Hall viscosity have an intrinsic thermal Hall conductivity, but Chen et al. (Phys. Rev. Lett. 124, 167601 (2020)) have argued that a significantly larger thermal Hall conductivity can arise from an extrinsic contribution which is inversely proportional to the density of impurities. We solve the Boltzmann equation for phonon transport and compute the temperature ($T$) dependence of the thermal Hall conductivity originating from skew scattering off point-like impurities. We find that the dominant source for thermal Hall transport is an interference between impurity skew scattering channels with opposite parity. The thermal Hall conductivity $\sim T^{d+2}$ at low $T$ in $d$ dimensions, and has a window of $T$-independent behavior for $T > T_{\rm imp}$, where $T_{\rm imp}$ is determined by the ratio of scattering potentials with opposite parity. We also consider the role of non-specular scattering off the sample boundary, and find that it leads to negligible corrections to thermal Hall transport at low $T$.

Exact Results on Dynamical Decoupling by $π$-Pulses in Quantum Information Processes

description: The aim of dynamical decoupling consists in the suppression of decoherence by appropriate coherent control of a quantum register. Effectively, the interaction with the environment is reduced. In particular, a sequence of $π$ pulses is considered. Here we present exact results on the suppression of the coupling of a quantum bit to its environment by optimized sequences of $π$ pulses. The effect of various cutoffs of the spectral density of the environment is investigated. As a result we show that the harder the cutoff is the better an optimized pulse sequence can deal with it. For cutoffs which are neither completely hard nor very soft we advocate iterated optimized sequences.
