description: Εισαγωγή: Η αιμορροφιλία Α και Β αποτελούν κληρονομικές διαταραχές της πήξης του αίματος οι οποίες οδηγούν σε αυτόματες ενδοαρθρικές αιμορραγίες. Η μειωμένη κινητικότητα λόγω της αιμορροφιλικής αρθροπάθειας και η αποφυγή ασκήσεων άρσης βάρους επιδρούν αρνητικά στην οστική πυκνότητα (BMD). Λίγες μελέτες υπάρχουν σχετικά με την επίπτωση της χαμηλής BMD στους αιμορροφιλικούς, χωρίς μέχρι στιγμής μελέτη εκτίμησης της επίδρασης αντι-οστεοπορωτικής αγωγής στους ασθενείς αυτούς. Σκοποί: Πρωτογενής σκοπός της μελέτης ήταν η εκτίμηση της επίπτωσης της χαμηλής BMD στους αιμορροφιλικούς και η συσχέτισή της με πιθανούς παράγοντες κινδύνου. Δευτερογενής σκοπός ήταν η εκτίμηση της επίδρασης της 12μηνης θεραπείας με ιμπανδρονάτη στη BMD και τους δείκτες οστικού μεταβολισμού (ΔΟΜ). Ασθενείς-Μέθοδοι: Έλαβαν μέρος ενήλικες ασθενείς με αιμορροφιλία Α και Β που παρακολουθούνται στο αιμορροφιλικό κέντρο Βορείου Ελλάδας. Μετρήθηκαν οι εξής ΔΟΜ: Ν-και C-τελοπεπτίδιο κολλαγόνου τύπου Ι (ΝΤΧ, CTX) και όξινη φωσφατάση ανθεκτική στη δράση του τρυγικού οξέος (TRAP-5b) (δείκτες οστικής απορρόφησης), οστεοκαλσίνη (OC) και οστικό κλάσμα αλκαλικής φωσφατάσης (b-ALP) (δείκτες οστικού σχηματισμού).

description: Background: Haemophilia A and B are hereditary bleeding disorders characterized by deficiency of factor VIII and IX, respectively, leading to spontaneous intra-articular bleeding episodes. Reduced mobility due to haemophilic arthropathy and avoidance of weight-bearing exercise negatively affect acquisition of peak bone mass and may increase bone resorption in adult life. Few studies have assessed the prevalence of low bone mineral density (BMD) in haemophiliacs. No study has evaluated the effects of anti-osteoporotic therapy on BMD in these patients.Aim: The primary end-point of this prospective study was to estimate the prevalence of low BMD in haemophiliacs and its association with potential risk factors. The secondary endpoint was to estimate the effect of 12-month therapy of oral ibandronate on BMD and bone turnover markers (BTM). Patients and Methods: Adult patients with haemophilia A and B followed-up in the Haemophilia Centre of Northern Greece were included. Bone resorption was assessed by: serum N- (NTX), C-terminal telopeptide of type 1 collagen (CTX) and tartrate-resistant acid phosphatase band 5b (TRAP-5b). Bone formation was assessed by osteocalcin (OC) and bone-specific alkaline phosphatase (b-ALP). Patients with osteoporosis or Z-score

description: Worldsheet string theory compactified on exceptional holomony manifolds is revisited following arXiv:1809.06376, where aspects of the chiral symmetry were described for the case where the compact space is a 7-dimensional G$_2$-holonomy manifold constructed as a Twisted Connected Sum. We reinterpret this result and extend it to Extra Twisted Connected Sum G$_2$-manifolds, and to 8-dimensional Generalized Connected Sum Spin(7)-manifolds. Automorphisms of the latter construction lead us to conjecture new mirror maps.

description: The article discusses the development of an approximation model of selected plastic and mechanical properties obtained from compression tests of model materials used in physical modeling. The use of physical modeling with the use of soft model materials such as a synthetic wax branch with various modifiers is a popular tool used as an alternative or verification of numerical modeling of bulk metal forming processes. In order to develop an algorithm to facilitate the choice of material model to simulate the behavior of real-metallic materials used in industrial production processes the induction of decision trees was used. First of all, the Statistica program was used for data mining, which made it possible to determine / find the relationship between the percentage of particular constituents of the model material (base material and modifiers) and yield strength, critical and maximum strain, and provide the opportunity to indicate the most important variables determining the shape of the stress – strain curve. Next, using the induction of decision trees, an approximation model was developed, which allowed to create an algorithm facilitating the selection of individual modifying components. The last stage of the research was verification of the correctness of the developed algorithm. The obtained research results indicate the possibility of using decision tree induction to approximate selected properties of modeling materials simulating the behavior of real materials, thus eliminating the need for costly and time-consuming experiments carried out on metallic material.

description: The aim of this study is the development of a short self-report tool of the Multidimensional Emotional Competence Questionnaire (MECQ). The MECQ consists of 109 items representing 11 factors resulting in an ineffective usability in combination with other measurement instruments and constitutes the reason for this study. Based on the selection criteria at content and statistical level, the results of the analyses of 777 participants suggest the creation of a 32-item short version (MECQ-s). Confirmatory factor analysis supports a four-dimensional structure, including 11 factors of emotional competence (EC). The internal consistency reliability coefficients ranged from α = .75 to .76. A comparison between the MECQ and the MECQ-s provides evidence of construct validity. The main difference between the MECQ-s and other existing self-report tools is its multidimensionality integrating several factors of EC. Researchers and practitioners can use it to measure, map and describe, or evaluate EC.

description: Το θέμα της διατριβής είναι η μελέτη του μοντέλου του Skyrme σε διάφορα πλαίσια: από τη γενική θεωρία της σχετικότητας ως την πυρηνική φυσική και φυσική συμπυκνωμένης ύλης. Δεδομένου ότι το μοντέλο δεν είναι ολοκληρώσιμο αλλά τοπολογικό, λόγω της ύπαρξης του ενεργειακού φράγματος Bogomol'nyi, η μελέτη του έχει βασιστεί σε τοπολογικές και γεωμετρικές τεχνικές. Επιπλέον, αριθμητικές μέθοδοι έχουν χρησιμοποιηθεί. Στα κεφάλαια 1 και 2, παρατίθονται τα μαθηματικά κίνητρα και οι τεχνικές για τη μελέτη του μοντέλου του Skyrme. Στο κεφάλαιο 3, εφαρμόζονται ανεξάρτητοι μετασχηματισμοί κλίμακας στο μοντέλο του Skyrme και τα προσεγγιστικά σκαρμιόνια κατασκευάζονται με βάση το θεώρημα του Derrick. Στο κεφάλαιο 4, το μοντέλο του Skyrme είναι συζευγμένο με βαρύτητα και λύσεις που περιγράφουν σκουληκότρυπες λαμβάνονται ως αποτέλεσμα. Ειδικότερα, οι σφαιρικά συμμετρικές Morris-Thorne σκουληκότρυπες παρουσιάζουν μια αστάθεια η οποία σχετίζεται με την Ellis σκουληκότρυπα, παρά το γεγονός ότι φέρουν τοπολογικό φορτίο. Στο κεφάλαιο 5 παρουσιάζεται μια διακριτή έκδοση του μοντέλου Skyrme βασιζόμενη στο ενεργειακό φράγμα τύπου Bogomol'nyi. Με αυτόν τον τρόπο προκύπτουν οι διακριτές σκαρμιονικές λύσεις και εξετάζεται η φασματική τους ευστάθεια.
description: The topic of the thesis is the study of the Skyrme model in various contexts: from general relativity to nuclear and condensed matter physics. Since the model is not integrable but topological due to the existence of a Bogomol'nyi energy bound, its study has been based on topological and geometrical techniques. In addition, numerical methods have been employed, as well. In chapters 1 and 2, we review the mathematical motivation and techniques for studying the Skyrme model. Chapter 3 applies independent rescalings to the Skyrme model and the approximate skyrmions are constructed based on Derrick's theorem. In chapter 4, the Skyrme model is coupled to gravity and wormhole solutions are obtained as a result. In particular, we show that all spherically symmetric Morris-Thorne wormholes exhibit an instability related to the Ellis wormhole, in spite of the fact that they do carry a topological charge. Chapter 5 presents a lattice version of the Skyrme model based on its Bogomol'nyi-type energy bound. That way, we obtain the lattice skyrmion solutions and examine their spectral stability.

Στη συνέχεια αναλύσαμε την ανθρωπολογία του Γρηγορίου Νύσσης, η οποία μας βοήθησε στην ανάδειξη της κοινωνικής του διδασκαλίας, αφού από αυτήν εξέρχονταν οι αρχές της πατερικής μεθοδολογίας για το πρόβλημα της κοινωνικής δικαιοσύνης. Τέλος, αναλύσαμε την κοινωνική του διδασκαλία και εκφέραμε μία πρόταση για το σήμερα.
description: The aim of this thesis was to study the texts of St. Gregory of Nyssa, and specially those dealing with his social teaching. We specifically investigated the social aspects of his works, such as his Homilies and actions he overtook, and also the social interventions he initiated as a Bishop, living in the 4th century A.D. We presented the opinions of Gregory of Nyssa had regarding the social problems that the people had to face at his time, and his pioneering views about important aspects such as wealth and poverty, borrowing and slavery, the relief of the sick and the poor, and the care for people living at the edge of society. To achieve this aim, we examined the historic, social, economic and cultural frame of the 4th century, in an effort to integrate Gregory of Nyssa in his era. In this way we managed to register the problems that existed and also the conditions that the Church Bishops were called to work, as leaders of their cities. Next we analyzed the anthropology of Gregory of Nyssa, which helped us to show his social teaching, as he followed the principles of the patristic methodology regarding the problem of social justice. Finally, we used Gregory’s social teachings to help us put forward a proposal that deals with today’s social problems.

description: We investigate the problem of fast-forwarding quantum evolution, whereby the dynamics of certain quantum systems can be simulated with gate complexity that is sublinear in the evolution time. We provide a definition of fast-forwarding that considers the model of quantum computation, the Hamiltonians that induce the evolution, and the properties of the initial states. Our definition accounts for any asymptotic complexity improvement of the general case and we use it to demonstrate fast-forwarding in several quantum systems. In particular, we show that some local spin systems whose Hamiltonians can be taken into block diagonal form using an efficient quantum circuit, such as those that are permutation-invariant, can be exponentially fast-forwarded. We also show that certain classes of positive semidefinite local spin systems, also known as frustration-free, can be polynomially fast-forwarded, provided the initial state is supported on a subspace of sufficiently low energies. Last, we show that all quadratic fermionic systems and number-conserving quadratic bosonic systems can be exponentially fast-forwarded in a model where quantum gates are exponentials of specific fermionic or bosonic operators, respectively. Our results extend the classes of physical Hamiltonians that were previously known to be fast-forwarded, while not necessarily requiring methods that diagonalize the Hamiltonians efficiently. We further develop a connection between fast-forwarding and precise energy measurements that also accounts for polynomial improvements.

description: Molybdenum disulfide (MoS2) is one of the most widely used solid lubricants applied in different ways on the surfaces under friction. In this work, AISI 316 austenitic stainless steel was coated with MoS2, using chemical vapor deposition (CVD) at four different temperatures (400, 500, 600 and 700°C). Coatings properties were investigated using SEM, EDX, XRD and FTIR, Hardness Tester and Roughness tester. The results showed that with simultaneous evaporation of sulfur and molybdenum trioxide (MoO3) in the CVD chamber, a uniform coating layer containing MoS2 and MoO2 phases was formed. Increase in the substrate temperature resulted in the rise in the amount of MoS2 to MoO2 phases. The thickness, grain size and the hardness of the coating were 17-29 μm, 50-120 nm and 260-480 HV respectively. Friction tests carried out using pin-on-plate method under normal loads of 10 N under ambient conditions showed values of the friction coefficient 0.25-0.40.

description: The fermionic quantum emulator (FQE) is a collection of protocols for emulating quantum dynamics of fermions efficiently taking advantage of common symmetries present in chemical, materials, and condensed-matter systems. The library is fully integrated with the OpenFermion software package and serves as the simulation backend. The FQE reduces memory footprint by exploiting number and spin symmetry along with custom evolution routines for sparse and dense Hamiltonians, allowing us to study significantly larger quantum circuits at modest computational cost when compared against qubit state vector simulators. This release paper outlines the technical details of the simulation methods and key advantages.

description: Using a combined quantum mechanical/classical method, we study the collisions of small Na clusters on large Ar clusters as a model for cluster deposit. We work out basic mechanisms by systematic variation of collision energy, system sizes, and orientations. The soft Ar material is found to serve as an extremely efficient shock absorber. The collisional energy is quickly transfered at first impact and the Na clusters are always captured by the Ar surface. The distribution of the collision energy into the Ar system proceeds very fast with velocity of sound. The relaxation of shapes goes at a slower pace using times of several ps. It produces a substantial rearrangement of the Ar system while the Na cluster remains rather robust.

description: Within the ongoing debate about de Sitter (dS) vacua in string theory, different aspects of explicit dS proposals have come under intense scrutiny. One key ingredient is D7-brane gaugino condensation, which is usually treated using effective 4d supergravity. However, it is clearly more desirable to derive the relevant scalar potential directly from a local 10d Lagrangian. Such a local 10d description captures the interactions among the various localized sources and the background fields which are smeared in the 4d Lagrangian. While progress in this endeavour has recently been made, some form of non-locality related to the 4-gaugino term has remained hidden in the available proposals. We spell out the local counterterm removing the divergence that arises when integrating out the 3-form flux and which, upon dimensional reduction, serves to reproduce the relevant part of the 4d supergravity action. This is both a step towards a more complete understanding of 10d type-IIB supergravity as well as specifically towards better control of dS constructions in string theory involving gaugino condensation.

Utopian design and planning
Creators: name: James, Antoni Michael
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this thesis is to provide a current overview of the subject of Utopian design in order to reaffirm its value as a component of planning methodology. From the relevant literature there is a wealth of comment on the need for such a paradigm expansion as well as a vast body of visions for alternate futures. Primarily a tool of physical planners, the Utopian process can be adapted to the broader context if appropriate methodology can be developed and integrated into the mainstream. The first chapter sets the context. It provides an overview of changing planning paradigms from the turn of the century and discusses areas of inadequacy in the current approach. The second chapter focuses on the subject of Utopian design, its approach, and fundamental elements as a preliminary foundation for methodological development. The third and fourth chapters examine a series of early and recent Utopian designs respectively. Early Utopian designs are described and analysed as to their impact on succeeding planning thought, thereby establishing credibility; recent Utopian designs are studied to speculate on the kinds of issues and options which planners may be involved in for the future. The fifth chapter is a speculative exercise which synthesizes ideas from the vast menu of the Utopian oeuvre into two diametrically opposed scenarios for Canada in the 21st Century. The intention is to illustrate the potential of Utopian designs in modeling alternatives for discussion and decision-making. In the final chapter, the thesis concludes by turning the discussion to other, non-physical aspects of planning where a Utopian element can be effective. It is hoped that further research into this subject can result in a broadening and balancing of the current planning paradigm and thus advance the role and responsibility of planners in better anticipating the future and in more creatively providing improved options for consideration.

description: We report on the performance of an end-to-end Bayesian analysis pipeline for detecting and characterizing galactic binary signals in simulated LISA data. Our principal analysis tool is the Blocked-Annealed Metropolis Hasting (BAM) algorithm, which has been optimized to search for tens of thousands of overlapping signals across the LISA band. The BAM algorithm employs Bayesian model selection to determine the number of resolvable sources, and provides posterior distribution functions for all the model parameters. The BAM algorithm performed almost flawlessly on all the Round 1 Mock LISA Data Challenge data sets, including those with many highly overlapping sources. The only misses were later traced to a coding error that affected high frequency sources. In addition to the BAM algorithm we also successfully tested a Genetic Algorithm (GA), but only on data sets with isolated signals as the GA has yet to be optimized to handle large numbers of overlapping signals.

description: PyArmadillo is a linear algebra library for the Python language, with the aim of closely mirroring the programming interface of the widely used Armadillo C++ library, which in turn is deliberately similar to Matlab. PyArmadillo hence facilitates algorithm prototyping with Matlab-like syntax directly in Python, and relatively straightforward conversion of PyArmadillo-based Python code into performant Armadillo-based C++ code. The converted code can be used for purposes such as speeding up Python-based programs in conjunction with pybind11, or the integration of algorithms originally prototyped in Python into larger C++ codebases. PyArmadillo provides objects for matrices and cubes, as well as over 200 associated functions for manipulating data stored in the objects. Integer, floating point and complex numbers are supported. Various matrix factorisations are provided through integration with LAPACK, or one of its high performance drop-in replacements such as Intel MKL or OpenBLAS. PyArmadillo is open-source software, distributed under the Apache 2.0 license; it can be obtained at https://pyarma.sourceforge.io or via the Python Package Index in precompiled form.

description: We discuss the conditions for a non-vanishing Dirac phase δand mixing angle θ_{13}, sources of CP violation in neutrino oscillations, to be uniquely responsible for the observed matter-antimatter asymmetry of the universe through leptogenesis. We show that this scenario, that we call δ-leptogenesis, is viable when the degenerate limit (DL) for the heavy right-handed (RH) neutrino spectrum is considered. We derive an interesting joint condition on \sinθ_{13} and the absolute neutrino mass scale that can be tested in future neutrino oscillation experiments. In the limit of hierarchical heavy RH neutrino spectrum (HL), we strengthen the previous result that δ-leptogenesis is only very marginally allowed, even when the production from the two heavier RH neutrinos is taken into account. An improved experimental upper bound on \sinθ_{13} and (or) an account of quantum kinetic effects could completely rule out this option in the future. Therefore, δ-leptogenesis can be also regarded as a motivation for models with degenerate heavy neutrino spectrum.

Long Term Simulations Of Astrophysical Jets; Energy Structure and Quasi-Periodic Ejection

description: We have performed self-consistent 2.5-dimensional nonsteady MHD numerical simulations of jet formation as long as possible, including the dynamics of accretion disks. Although the previous nonsteady MHD simulations for astrophysical jets revealed that the characteristics of nonsteady jets are similar to those of steady jets, the calculation time of these simulations is very short compared with the time scale of observed jets. Thus we have investigated long term evolutions of mass accretion rate, mass outflow rate, jet velocity, and various energy flux. We found that the ejection of jet is quasi-periodic. The period of the ejection is related to the time needed for the initial magnetic filed to be twisted to generate toroidal filed. We compare our results with both the steady state theory and previous 2.5-dimensional nonsteady MHD simulations.

Type-X two Higgs doublet model in light of the muon $\mathbf{g-2}$: confronting Higgs and collider data

description: The recent Fermilab measurement of the muon anomalous magnetic moment yields $4.2 σ$ deviations from the SM prediction when combined with the BNL E821 experiment results. In the Type-X two Higgs doublet model, we study the consequence of imposing the observed muon $g-2$, along with the constraints from theoretical stabilities, electroweak oblique parameters, Higgs precision data, and direct searches. For a comprehensive study, we scan the whole parameter space in two scenarios, the normal scenario where $h_{\rm SM} = h$ and the inverted scenario where $h_{\rm SM}=H$, where $h$ ($H$) is the light (heavy) CP-even Higgs boson. We found that large $\tanβ$ (above 100) and light pseudoscalar mass $M_A$ are required to explain the muon $g-2$ anomaly. This breaks the theoretical stability unless the scalar masses satisfy $M_A^2 \simeq M_{H^\pm}^2 \simeq m_{12}^2 \tanβ\approx M_{H/h}^2$. The direct search bounds at the LEP and LHC exclude the light $A$ window with $M_A \lesssim 62.5~$GeV. We also show that the observed electron anomalous magnetic moment is consistent with the model prediction, but the lepton flavor universality data in the $τ$ and $Z$ decays are not. For a separate exploration of the model, we propose the golden mode $pp \to A h/AH \to 4 τ$ at the HL-LHC.

Hypergeometric Functions at Unit Argument: Simple Derivation of Old and New Identities

description: The main goal of this paper is to derive a number of identities for the generalized hypergeometric function evaluated at unity and for certain terminating multivariate hypergeometric functions from the symmetries and other properties of Meijer's $G$ function. For instance, we recover two- and three-term Thomae relations for ${}_3F_2$, give two- and three-term transformations for ${}_4F_3$ with one unit shift and ${}_5F_4$ with two unit shifts in the parameters, establish multi-term identities for general ${}_{p}F_{p-1}$ and several transformations for terminating Kampé de Fériet and Srivastava $F^{(3)}$ functions. We further present a presumably new formula for analytic continuation of ${}_pF_{p-1}(1)$ in parameters and reveal somewhat unexpected connections between the generalized hypergeometric functions and the generalized and ordinary Bernoulli polynomials. Finally, we exploit some recent duality relations for the generalized hypergeometric and $q$-hypergeometric functions to derive multi-term relations for terminating series.

description: We establish the interrelation between the QCD scalar response of the nuclear medium and its response to a scalar probe coupled to nucleons, such as the scalar meson responsible for the nuclear binding. The relation that we derive applies at the nucleonic as well as at the nuclear levels. Non trivial consequences follow. In particular it opens the possibility of relating medium effects in the scalar meson exchange or three-body forces of nuclear physics to QCD lattice studies of the nucleon mass

description: Current techniques for generating a knowledge space, such as QUERY, guarantees that the resulting structure is closed under union, but not that it satisfies wellgradedness, which is one of the defining conditions for a learning space. We give necessary and sufficient conditions on the base of a union-closed set family that ensures that the family is well-graded. We consider two cases, depending on whether or not the family contains the empty set. We also provide algorithms for efficiently testing these conditions, and for augmenting a set family in a minimal way to one that satisfies these conditions.

Rabi Regime of Current Rectification in Solids

description: We investigate rectified currents in response to oscillating electric fields in systems lacking inversion and time-reversal symmetries. These currents, in second-order perturbation theory, are inversely proportional to the relaxation rate, and, therefore, naively diverge in the ideal clean limit. Employing a combination of the non-equilibrium Green function technique and Floquet theory, we show that this is an artifact of perturbation theory, and that there is a well-defined periodic steady-state akin to Rabi oscillations leading to finite rectified currents in the limit of weak coupling to a thermal bath. In this Rabi regime the rectified current scales as the square root of the radiation intensity, in contrast with the linear scaling of the perturbative regime, allowing to readily diagnose it in experiments. More generally, our description provides a smooth interpolation from the ideal Periodic Gibbs Ensemble describing the Rabi oscillations of a closed system to the perturbative regime of rapid relaxation due to strong coupling to a thermal bath.

description: In this study, high performance magnesium-yttria nanocomposite’s room temperature, strength and ductility were significantly enhanced by the dispersion of nano-sized nickel particles using powder blending and a microwave sintering process. The strengthening effect of the dispersed nano-sized nickel particles was consistent up to 100°C and then it gradually diminished with further increases in the test temperature. The ductility of the magnesium-yttria nanocomposite remained unaffected by the dispersed nano-sized nickel particles up to 100°C. Impressively, it was enhanced at 150°C and above, leading to the possibility of the near net shape fabrication of the nanocomposite at a significantly low temperature.
