description: Ὁ Μέγας Ἀθανάσιος, μέ τήν βαθεία κατανόησή του γιά τήν κρίση τῆς ἐποχῆς του, δηλαδή γιά τόν ἀρειανισμό, ἔφτασε στό οὐσιαστικό πρόβλημα τοῦ Ἀρείου, πού εἶναι ἡ θεώρηση περί τῆς δημιουργίας. Γι’ αὐτό ξεκίνησε ἀπό ὅτι ἡ δημιουργία ἔγινε «ἐξ οὐκ ὄντων» τονίζοντας τήν ὑπερβατικότητα καί τήν παν¬ταχοῦ παρουσία τοῦ Θεοῦ. Ὁ ἄνθρωπος πρίν τήν πτώση δημιουργήθηκε κατ’ εἰκόνα τοῦ Θεοῦ μέ σκοπό νά φτάσει στό καθ’ ὁμοίωση, δηλαδή στήν θέωση. Δυστυχῶς ὁ ἄνθρωπος μέ τήν παράβαση τῆς θείας ἐντολῆς δέν ἐξασφάλισε τήν πορεία του ἀπό τό κατ’ εἰκόνα στήν θέωση, ἀντί θέωση στήν πτώση. Ὁ Θεός μέ τή θεία του χάρη μέ τήν ὁποία ἀσχολήθηκε ἀρκετά ὁ Μέγας Ἀθανάσιος, χορηγεῖ τήν σωτηρία στό μεταπτωτικό ἄνθρωπο. Ἡ σωτηριολογία τοῦ Πατρός περιέχει τίς τρεῖς θεωρίες περί τῆς σωτηρίας, διορθώνοντας τήν τρίτη καί κάνοντας διάκριση στόν σταυρικό θάνατο σέ προσφορά καί θυσία. Ἔτσι μέ τήν σωτηρία ἔγινε ὄχι μόνο ἡ ἀποκατάσταση τοῦ μεταπτωτικοῦ ἀνθρώπου, ἀλλά ἐπί πλέον καί ἡ θέωσή του.
description: St. Athanasius had deep comprehension of the crisis of the arianisme at his time. He reached to the essential problem of Arius which is the look about the Creation. This is why he started his theology from the creation which is done from non-existence. And then St. Athanasius emphasized the omnipotence and the omnipresence of God. Before the fall the man had created in the image of God to reach into likeness of God that is into deification. Unfortunately, because the transgression of the divine commandment, the man did not secure his course from the image into likeness namely into deification, and in stead of deification into the fall. By the divine grace, with which St. Athanasius was occupied enough, God grants the salvation to after-falled man. The soteriology of the father contains the three theories about the salvation. But the corrected the third theory and made discrimination in the death of a cross in offer and sacrifice. So, with the salvation the result is no only the restoration but more over the deification to the after-falled man.

description: We report a $μ$SR investigation of a non-centrosymmetric superconductor (LaNiC$_2$) in single crystal form. Compared to previous $μ$SR studies of non-centrosymmetric superconducting polycrystalline and powder samples, the unambiguous orientation of single crystals enables a simultaneous determination of the absolute value of the magnetic penetration depth and the vortex core size from measurements that probe the magnetic field distribution in the vortex state. The magnetic field dependence of these quantities unambiguously demonstrates the presence of two nodeless superconducting energy gaps. In addition, we detect weak internal magnetic fields in the superconducting phase, confirming earlier $μ$SR evidence for a time-reversal symmetry breaking superconducting state. Our results suggest that Cooper pairing in LaNiC$_2$ is characterized by the same interorbital equal-spin pairing model introduced to describe the pairing state in the centrosymmetric superconductor LaNiGa$_2$.

Effect of atmospheric pressure fluctuations on bulk gas flow and composition of flavour volatiles from bulky plant tissues
Creators: name: Buckley, Katherine Elaine
Publisher: name: University of British Columbia
Year: 2009

description: The occurrence of total gas pressure gradients, which act as a driving force for the mass transport of fluids, may be common phenomena in plant organs. A gas-exchange system was devised to characterize changes in CO₂ emission rates of greenhouse tomato fruit (Lycopersicon esculentum L. Dombito), greenhouse green bell pepper fruit (Capsicum annum L. Doria), slicing cucumber fruit (Cucumis sativa L. Straight Eight and Sweet Success) and jumbo yellow onion bulbs (Allium cepa L.) in response to the imposition of total gas pressure gradients. Cyclical variations in atmospheric pressure induced significantly higher rates of gas exchange in peppers and onions but not in tomatoes and cucumbers. Oxygen concentration significantly affected carbon dioxide efflux rates in onions subjected to variable pressures. Temperature had no significant effect on relative efflux rates in any of the plant organs used in this study. Duration of the interval between varying pressure treatments was an important factor in CO₂ emission rate in onions, tomatoes and cucumbers. The differing response of various commodities to varying pressure treatments was probably due to differences in routes of gas exchange as well as intercellular space volumes and internal structure. To determine if variable pressure treatments had a metabolic effect on tissues, a dynamic head-space sampling technique was developed to collect and concentrate aroma volatiles for analysis by gas chromatography/mass spectrometry. Principal component analysis of pepper, onion and tomato volatiles revealed that variable pressure storage increased levels of compounds associated with oxidation compared to those stored under constant pressure. Data from peppers stored under 3% oxygen and variable pressures for 1 week indicated that compounds associated with off-flavours were lower than in peppers stored in air.

description: We analyse the presence of nonradial oscillations in Cepheids, a problem which has not been theoretically revised since the work of Dziembowsky (1977) and Osaki (1977). Our analysis is motivated by a work of Moskalik et al. (2004) which reports the detec tion of low amplitude periodicities in a few Cepheids of the large Magellanic cloud. These newly discovered periodicities were interpreted as nonradial modes.} {Based on linear nonadiabatic stability analysis, our goal is to reanalyse the presence and stability of nonradial modes, taking into account improvement in the main input phys ics required for the modelling of Cepheids.} {We compare the results obtained from two different numerical methods used to solve the set of differential equations: a matrix method and the Ricatti method.} {We show the limitation of the matrix method to find low order p-modes ($l<6$), because of their dual character in evolved stars such as Cepheids. For higher order p-modes, we find an excellent agreement between the two methods.} {No nonradial instability is found below $l=5$, whereas many unstable nonradial modes exist for higher orders. We also find that nonradial modes remain unstable, even at hotter effective temperatures than the blue edge of the Cepheid instability strip, where no radial pulsations are expected.

description: Transfermium nuclei (101$\leq$Z$\leq$110) are investigated thoroughly to describe structural properties viz. deformation, radii, shapes, magicity, etc. as well as their probable decay chains. These properties are explored using relativistic mean-field (RMF) approach and compared with other theories along with available experimental data. Neutron numbers N$=$152 and 162 have come forth with a deformed shell gap whereas N$=$184 is ensured as a spherical magic number. The region with N$>$168 bears witness of the phenomenon of shape transition and shape coexistence for all the considered isotopic chains. Experimental $α$-decay half-lives are compared with our theoretical half-lives obtained by using various empirical/semi-empirical formulas. The recent formula proposed by Manjunatha \textit{et al.}, which results best among the considered 10 formulas, is further modified by adding asymmetry dependent terms ($I$ and $I^2$). This modified Manjunatha formula is utilized to predict probable $α$-decay chains that are found in excellent agreement with available experimental data.

description: This paper continues a research program on constructive investigations of non-commutative Ore localizations, initiated in our previous papers, and particularly touches the constructiveness of arithmetics within such localizations. Earlier we have introduced monoidal, geometric and rational types of localizations of domains as objects of our studies. Here we extend this classification to rings with zero divisors and consider Ore sets of the mentioned types which are commutative enough: such a set either belongs to a commutative algebra or it is central or its elements commute pairwise. By using the systematic approach we have developed before, we prove that arithmetic within the localization of a commutative polynomial algebra is constructive and give the necessary algorithms. We also address the important question of computing the local closure of ideals which is also known as the desingularization, and present an algorithm for the computation of the symbolic power of a given ideal in a commutative ring. We also provide algorithms to compute local closures for certain non-commutative rings with respect to Ore sets with enough commutativity.

description: We present the first direct distance determination to a detached eclipsing binary in M33, which was found by the DIRECT Project. Located in the OB 66 association at coordinates (alpha, delta)=(01:33:46.17,+30:44:39.9) for J2000.0, it was one of the most suitable detached eclipsing binaries found by DIRECT for distance determination, given its apparent magnitude and orbital period. We obtained follow-up BV time series photometry, JHKs photometry and optical spectroscopy from which we determined the parameters of the system. It contains two O7 main sequence stars with masses of 33.4+/-3.5 Mo and 30.0+/-3.3 Mo and radii of 12.3+/-0.4 Ro and 8.8+/-0.3 Ro, respectively. We derive temperatures of 37000+/-1500 K and 35600+/-1500 K. Using BVRJHKs photometry for the flux calibration, we obtain a distance modulus of 24.92+/-0.12 mag (964+/-54 kpc), which is ~0.3 mag longer than the Key Project distance to M33. We discuss the implications of our result and the importance of establishing M33 as an independent rung on the cosmological distance ladder.

description: Radar sensors are crucial for environment perception of driver assistance systems as well as autonomous cars. Key performance factors are a fine range resolution and the possibility to directly measure velocity. With a rising number of radar sensors and the so far unregulated automotive radar frequency band, mutual interference is inevitable and must be dealt with. Sensors must be capable of detecting, or even mitigating the harmful effects of interference, which include a decreased detection sensitivity. In this paper, we evaluate a Convolutional Neural Network (CNN)-based approach for interference mitigation on real-world radar measurements. We combine real measurements with simulated interference in order to create input-output data suitable for training the model. We analyze the performance to model complexity relation on simulated and measurement data, based on an extensive parameter search. Further, a finite sample size performance comparison shows the effectiveness of the model trained on either simulated or real data as well as for transfer learning. A comparative performance analysis with the state of the art emphasizes the potential of CNN-based models for interference mitigation and denoising of real-world measurements, also considering resource constraints of the hardware.

description: The objective of this study was to develop and use a mathematical model for the simulation of phosphorus balance in the lowland paddy-rice fields under Greek conditions.The development of the model was achieved by modifying the phosphorus sub-model of the GLEAMS-PR, which is a modification of GLEAMS v3.0 for water and nitrogen balance in rice fields. The modifications in the phosphorus sub-model included the evaluation of phosphorus balance and algae growth in the ponded water. For the calibration and evaluation of the model, experimental measurements were performed in two experimental rice-fields (A and B) in Sindos region, at Thessaloniki plain in northern Greece for one year (2005). The measurements included labile, total, mineral and organic phosphorus in the soil, total phosphorus concentration of dry plant biomass, concentrations of total phosphorus in irrigation and surface runoff water. The model was calibrated and evaluated by comparing simulation results with measured data of the field A and B, respectively.

description: In this manuscript we investigate the one-dimensional anisotropic XY model with ferromagnetic and antiferromagnetic interactions, which gives more interesting phase diagrams and dynamic critical behaviors. By using quantum renormalization-group method, we find that there are three phases in the system: antiferromagnetic Ising phase ordered in "x direction", spin-fluid phase and ferromagnetic Ising phase ordered in "y direction". In order to study the dynamical critical behaviors of the system, two quantum quenching methods are used. In both cases, the concurrence, a measure of entanglement, oscillates periodically over time. We show that the periods are the same and can be used as a new order parameter for quantum phase transitions. For further discussion, we derive the scaling exponent, θ, and correlation length exponent, ν, from the scaling behavior of the evolution period.

A Unifying Framework for Self-consistent Gravitational Lensing and Stellar Dynamics Analyses of Early-Type Galaxies

description: Gravitational lensing and stellar dynamics are two independent methods, based solely on gravity, to study the mass distributions of galaxies. Both methods suffer from degeneracies, however, that are difficult to break. In this paper, we present a new framework that self-consistently unifies gravitational lensing and stellar dynamics. This approach breaks some of classical degeneracies that have limited their individual usage, in particular in the study of high-redshift galaxies. The methodology is based on the premise that, for any given galaxy potential, the mapping of both the unknown lensed source brightness distribution and the stellar phase-space distribution function on to the photometric and kinematic observables, can be cast as a single set of coupled linear equations. This set of linear equations is solved, maximizing the likelihood penalty function. The evidence penalty function, as derived from Bayesian statistics, subsequently allows the best potential-model parameters to be found and potential-model families, or other model assumptions (e.g. PSF), to be quantitatively ranked. We have implemented a fast algorithm that solves for the maximum-likelihood pixelized lensed source brightness distribution and the two-integral stellar phase-space distribution function f(E, L_z), assuming axisymmetric potentials. To make the method practical, we have devised a new Monte-Carlo approach to Schwarzschild's orbital superposition method, based on the superposition of two-integral (E and L_z) toroidal components, to find the maximum-likelihood two-integral distribution function in a matter of seconds in any axisymmetric potential. The non-linear parameters of the potential are subsequently found through a hybrid MCMC and Simplex optimization of the evidence. (Abridged)

description: Σε δύο εδάφη από την Β. Ελλάδα, ένα όξινο (Γαλάτιστας) και ένα ελαφρώς όξινο (Μεσήμβριας), έγιναν πειράματα προσρόφησης και κινητικής Cu, Zn και Cu+Zn. Το φαινόμενο της προσρόφησης του Cu περιγράφετε καλύτερα από την μη γραμμική εξίσωση του Freundlich, ενώ του Zn από την μη γραμμική εξίσωση του Langmuir. Το έδαφος της Μεσήμβριας προσροφούσε περισσότερο Cu απ’ ότι Zn, αλλά ο Zn προσροφήθηκε σε υψηλότερες ενεργειακά θέσεις απ’ ότι ο Cu, ενώ το έδαφος της Γαλάτιστας προσροφούσε τις ίδιες ποσότητες Cu ή Zn. Παρουσία των δύο στοιχείων στο διάλυμα ισορροπίας, το έδαφος της Μεσήμβριας προσροφούσε περισσότερο Cu απ’ ότι Zn, ενώ στο έδαφος της Γαλάτιστας προσροφήθηκε περισσότερος Cu αφήνοντας τα ιόντα του Zn στο διάλυμα ισορροπίας (Kd medium Cu = 9,808 ml/g και Kd medium Zn = 0,066 ml/g). Η Ι.Α.Κ., το pH και πιθανόν η ορυκτολογική σύσταση της αργίλου επηρέασαν την προσρόφηση των δύο στοιχείων στα εδάφη αυτά. Στα πειραματικά δεδομένα της κινητικής προσρόφησης η εξίσωση του Elovich περιέγραφε καλύτερα το φαινόμενο της κινητικής για τον Cu και τον Zn για τα δύο εδάφη. Επίσης από την κινητική προσρόφησης προκύπτει ότι η διάχυση είναι ένας από τους παράγοντες που επηρέασαν την ταχύτητα της προσρόφησης, καθώς και η συγκέντρωση των ιόντων στο διάλυμα ισορροπίας και οι θέσεις προσρόφησης της στερεής φάσης.
description: Tow soils from N. Greece, an acid one (Galatista) and a slightly acid (Mesimvria) were used to study Cu, Zn and Cu+Zn adsorption and kinetics. Cu adsorption was better described by the non linear equation of Freundlich, while Zn adsorption was better described by the non linear equation of Langmuir. Mesimvria soil was adsorbing more Cu than Zn, but Zn was adsorbed in sites of higher energy in respect to Cu. Galatista soil was adsorbing the same quantities of Cu or Zn. In the presence of both elements in the equilibrium solution Mesimvria soil was adsorbing more Cu than Zn. In Galatista soil was observed an affinity for Cu as Zn ions remained in the equilibrium solution (Kd medium Cu = 9,808 ml/g and Kd medium Zn = 0,066 ml/g). The adsorption of the tow elements was affected by the CEC and the pH and probably by clay mineralogy of the soils used. The application of Elovich equation on the experimental data described better the kinetics of Cu and Zn, in both soils. Also, the adsorption kinetics revealed that the diffusion, the ion concentration in the equilibrium solution and the adsorption sites of the soil solid phase control the rate of the adsorption.
Competition in auditing : a spatial approach
Creators: name: Chan, Derek Kwok-Wing
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation develops variants of the well-known Hotelling’s location model to examine the nature of competition in the audit market where audit firms make strategic specialization and pricing decisions. In a multi-period spatial oligopoly model of auditing competition, audit firms obtain market power through their service specialization with respect to client characteristics relevant to audit production. This market power allows audit firms to price discriminate among clients. Competition among audit firms is localized: an audit firm optimally charges a client, to whom it has the lowest auditing cost to serve, the marginal auditing cost of the second lowest-cost audit firm. These equilibrium audit firms’ pricing strategies result in an allocation of clients’ surplus and audit firms’ profits that lies in the core of the economy. The existence of a specialization-pricing equilibrium is also established. In equilibrium, given its rivals’ specializations, each audit firm’s profit is maximized by choosing a specialization that maximizes the social welfare (the sum of clients’ surplus and audit firms’ profits). Moreover, audit firms never choose the same specialization in equilibrium. Instead, in order to earn rents as ‘local monopolists’, audit firms differentiate themselves from each other. This result is consistent with a widely held notion that audit firms search for ‘niche’ markets, such as industry specialization, to increase their profits. The dissertation then focuses on a two-period spatial duopoly model in which the market power created by audit firm specialization is now further fortified by the presence of auditors’ learning and clients’ switching costs. In this case, audit firms optimally price discriminate among clients by offering them ‘specialization-and-relationship-specific’ audit fee schedules. The practice of ‘low-balling’ is found to be a natural consequence of the competition among audit firms. However, low-balling occurs only in a certain market segment where audit firms compete quite fiercely. The analysis also demonstrates how equilibrium audit fee schedules, audit firms’ specializations and profits, clients’ surplus, and social welfare depend on the auditing costs, the learning rate, and the switching costs. Some interesting policy implications are illustrated. Finally, the model is used to analyze the impact of banning audit firms from the practice of low-balling. It is demonstrated that even though a policy of banning low-balling always reduces competition, it improves social efficiency in some cases.

description: With a semiclassical quasistatic model we identify the distinct roles of nuclear Coulomb attraction, final state electron repulsion and electron-field interaction in forming the finger-like (or V-shaped) pattern in the correlated electron momentum distribution for Helium double ionization [Phys. Rev. Lett. \textbf{99}, 263002; \emph{ibid}, 263003 (2007)]. The underlying microscopic trajectory configurations responsible for asymmetric electron energy sharing after electron-electron collision have been uncovered and corresponding sub-cycle dynamics are analyzed. The correlation pattern is found to be sensitive to the transverse momentum of correlated electrons.

description: Currently, newly developed artificial intelligence techniques, in particular convolutional neural networks, are being investigated for use in data-processing and classification of particle physics collider data. One such challenging task is to distinguish quark-initiated jets from gluon-initiated jets. Following previous work, we treat the jet as an image by pixelizing track information and calorimeter deposits as reconstructed by the detector. We test the deep learning paradigm by training several recently developed, state-of-the-art convolutional neural networks on the quark-gluon discrimination task. We compare the results obtained using various network architectures trained for quark-gluon discrimination and also a boosted decision tree (BDT) trained on summary variables.

description: The paper examines the formulation of the problem of combining a range of knowledge from neuroscience and cognitive technologies in the study of complex systems - socio-economic, environmental, political. A brief description of neuroscience and cognitive modeling is given. It is hypothesized that a cognitive map, as a structure of cause-and-effect relationships between the considered concepts of the complex system being studied, can exist in the brain of the decision maker as some kind of neural structure. An example of cognitive modeling of the problem of civilizational strategy in geopolitics is given.

description: We analyze the algebra of Dirac observables of the relativistic particle in four space-time dimensions. We show that the position observables become non-commutative and the commutation relations lead to a structure very similar to the non-commutative geometry of Deformed Special Relativity (DSR). In this framework, it appears natural to consider the 4d relativistic particle as a five dimensional massless particle. We study its quantization in terms of wave functions on the 5d light cone. We introduce the corresponding five-dimensional action principle and analyze how it reproduces the physics of the 4d relativistic particle. The formalism is naturally subject to divergences and we show that DSR arises as a natural regularization: the 5d light cone is regularized as the de Sitter space. We interpret the fifth coordinate as the particle's proper time while the fifth moment can be understood as the mass. Finally, we show how to formulate the Feynman propagator and the Feynman amplitudes of quantum field theory in this context in terms of Dirac observables. This provides new insights for the construction of observables and scattering amplitudes in DSR.

description: Hospital acquired infections are infections that occur in patients during hospitalization, which were not present at the time of admission. They are among the most common adverse events in healthcare around the world, leading to increased mortality and morbidity rates, prolonged hospitalization periods and considerable financial burden on both hospitals and patients. Preventive guidelines and regulations have been devised, however compliance to these is frequently poor and there is much room for improvement. This paper presents the prototype of an extensible, configurable cyber-physical system, developed under European Union funding, that will assist in the prevention of hospital infections and outbreaks. Integrating a wireless sensor network for the surveillance of clinical processes with configurable monitoring software built around a workflow engine as key component, our solution detects deviations from established hygiene practices and provides real-time information and alerts whenever an infection risk is discovered. The platform is described from both hardware and software perspective, with emphasis on the wireless network's elements as well as the most important software components. Furthermore, two clinical workflows of different complexity, which are included in the system prototype are detailed. The finalized system is expected to facilitate the creation and automated monitoring of clinical workflows that are associated with over 90% of hospital infections.

description: We address the electronic properties of quantum dots in the two-dimensional $α-\mathcal{T}_3$ lattice when subjected to a perpendicular magnetic field. Implementing an infinite mass boundary condition, we first solve the eigenvalue problem for an isolated quantum dot in the low-energy, long-wavelength approximation where the system is described by an effective Dirac-like Hamiltonian that interpolates between the graphene (pseudospin 1/2) and Dice (pseudospin 1) limits. Results are compared to a full numerical (finite-mass) tight-binding lattice calculation. In a second step we analyse charge transport through a contacted $α-\mathcal{T}_3$ quantum dot in a magnetic field by calculating the local density of states and the conductance within the kernel polynomial and Landauer-Büttiker approaches. Thereby the influence of a disordered environment is discussed as well.

description: A new approach for analytically solving quantum nonlinear Langevin equations is proposed and applied to calculations of spectra of superradiant lasers where collective effects play an important role. We calculate lasing spectra for arbitrary pump rates and recover well-known results such as the pump dependence of the laser linewidth across the threshold region. We predict new sideband peaks in the spectrum of superradiant lasers with large relaxation oscillations as well as new nonlinear structures in the lasing spectra for weak pump rates. Our approach sheds new light on the importance of population fluctuations in the narrowing of the laser linewidth, in the structure of the lasing spectrum, and in the transition to coherent operation.

description: In several domains it is crucial to store and manipulate data whose origin needs to be completely traceable to guarantee the consistency, trustworthiness and reliability on the data itself typically for ethical and legal reasons. It is also important to guarantee that such properties are also carried further when such data is composed and processed into new data. In this article we present the main requirements and theorethical problems that arise by the design of a system supporting data with such capabilities. We present an architecture for implementing a system as well as a prototype developed in Pharo.

description: In this note we consider the continuous Galerkin time stepping method of arbitrary order as a possible discretization scheme of nonlinear initial value problems. In addition, we develop and generalize a well known existing result for the discrete solution by applying a general linearizing procedure to the nonlinear discrete scheme including also the simplified Newton solution procedure. In particular, the presented existence results are implied by choosing sufficient small time steps locally. Furthermore, the established existence results are independent of the local approximation order. Moreover, we will see that the proposed solution scheme is able to significantly reduce the number of iterations. Finally, based on existing and well known a priori error estimates for the discrete solution, we present some numerical experiments that highlight the proposed results of this note.
Extremum Seeking Control with Attenuated Steady-State Oscillations

description: We propose two perturbation-based extremum seeking control (ESC) schemes for general single input single output nonlinear dynamical systems, having structures similar to that of the classical ESC scheme. We propose novel adaptation laws for the excitation signal amplitudes in each scheme that drive the amplitudes to zero. The rates of decay for both the laws are governed by the gradient measures of the unknown reference-to-output equilibrium map. We show that the proposed ESC schemes achieve practical asymptotic convergence to the extremum with a proper tuning of the parameters in the proposed schemes. As the extremum is reached, and the magnitudes of the gradient measures become small, the excitation signal amplitudes converge to zero. Thus, the proposed schemes ensure that the excitation signal is attenuated as the system output converges to a neighborhood of the extremum and the steady-state oscillations about the extremum, typically observed for the classical ESC schemes, are attenuated. Simulation examples are included to illustrate the effectiveness of the proposed schemes.
