description: We analyze in detail the highly damped quasinormal modes of $d$-dimensional Reissner-Nordstr$\ddot{\rm{o}}$m black holes with small charge, paying particular attention to the large but finite damping limit in which the Schwarzschild results should be valid. In the infinite damping limit, we confirm using different methods the results obtained previously in the literature for higher dimensional Reissner-Nordstr$\ddot{\rm{o}}$m black holes. Using a combination of analytic and numerical techniques we also calculate the transition of the real part of the quasinormal mode frequency from the Reissner-Nordstr$\ddot{\rm{o}}$m value for very large damping to the Schwarzschild value of $\ln(3) T_{bh}$ for intermediate damping. The real frequency does not interpolate smoothly between the two values. Instead there is a critical value of the damping at which the topology of the Stokes/anti-Stokes lines change, and the real part of the quasinormal mode frequency dips to zero.

description: Accurate forecasting of the arrival time and arrival speed of coronal mass ejections (CMEs) is a unsolved problem in space weather research. In this study, a comparison of the predicted arrival times and speeds for each CME based, independently, on the inputs from the two STEREO vantage points is carried out. We perform hindcasts using ELlipse Evolution model based on Heliospheric Imager observations (ELEvoHI) ensemble modelling. An estimate of the ambient solar wind conditions is obtained by the Wang-Sheeley-Arge/Heliospheric Upwind eXtrapolation (WSA/HUX) model combination that serves as input to ELEvoHI. We carefully select 12 CMEs between February 2010 and July 2012 that show clear signatures in both STEREO-A and STEREO-B HI time-elongation maps, that propagate close to the ecliptic plane, and that have corresponding in situ signatures at Earth. We find a mean arrival time difference of 6.5 hrs between predictions from the two different viewpoints, which can reach up to 9.5 hrs for individual CMEs, while the mean arrival speed difference is 63 km s$^{-1}$. An ambient solar wind with a large speed variance leads to larger differences in the STEREO-A and STEREO-B CME arrival time predictions ($cc~=~0.92$). Additionally, we compare the predicted arrivals, from both spacecraft, to the actual in situ arrivals at Earth and find a mean absolute error of 7.5 $\pm$ 9.5 hrs for the arrival time and 87 $\pm$ 111 km s$^{-1}$ for the arrival speed. There is no tendency for one spacecraft to provide more accurate arrival predictions than the other.
Effect of measurement probes upon the conductance of an interacting nanosystem: Detection of an attached ring by non local many body effects

description: We consider a nanosystem connected to measurement probes via leads. When a magnetic flux is varied through a ring attached to one lead at a distance Lc from the nanosystem, the effective nanosystem transmission |ts|^2 exhibits Aharonov-Bohm oscillations if the electrons interact inside the nanosystem. These oscillations can be very large if Lc is small and if the nanosystem has almost degenerate levels which are put near the Fermi energy by a local gate.
Legal controls of corporate management in Japan : comparisons with common law jurisdictions
Creators: name: Oyama, Kuniko
Publisher: name: University of British Columbia
Year: 2008

description: Corporate management involves various individuals, groups and organizations involved with corporations. Among them, in theory, the shareholders and directors play the critical roles in managing the corporations. Shareholders have the ultimate power in managing a corporation, and directors actually exercise these powers under the instruction of shareholders. Directors are also conferred with statutory powers to carry on the day-to-day business of their corporations. Between these two main actors within a corporation, conflicts sometimes arise. Thus, there is a need for corporate law whose functions include regulating how these powers ought to be exercised by them. This thesis attempts to analyze the legal controls regulating shareholders and directors under Japanese corporate law, primarily by focusing on legal rules governing the general meeting, through which shareholders exercise their powers, and the legal duties of directors. Through the examination of such legal controls on the general meeting and directors, it is hoped that the role of corporate law in Japanese corporate society will be brought to light. To elucidate the Japanese legal system regulating corporate management, comparison will be made to relevant areas of the law in common law jurisdictions, in particular that of Canada. This thesis also tries to shed some light on sociological peculiarities of Japanese society which may have influenced the present legal system affecting corporate management in Japan.

description: Graph neural networks (GNNs) have been widely used to learn vector representation of graph-structured data and achieved better task performance than conventional methods. The foundation of GNNs is the message passing procedure, which propagates the information in a node to its neighbors. Since this procedure proceeds one step per layer, the range of the information propagation among nodes is small in the lower layers, and it expands toward the higher layers. Therefore, a GNN model has to be deep enough to capture global structural information in a graph. On the other hand, it is known that deep GNN models suffer from performance degradation because they lose nodes' local information, which would be essential for good model performance, through many message passing steps. In this study, we propose multi-level attention pooling (MLAP) for graph-level classification tasks, which can adapt to both local and global structural information in a graph. It has an attention pooling layer for each message passing step and computes the final graph representation by unifying the layer-wise graph representations. The MLAP architecture allows models to utilize the structural information of graphs with multiple levels of localities because it preserves layer-wise information before losing them due to oversmoothing. Results of our experiments show that the MLAP architecture improves the graph classification performance compared to the baseline architectures. In addition, analyses on the layer-wise graph representations suggest that aggregating information from multiple levels of localities indeed has the potential to improve the discriminability of learned graph representations.

Galaxy surveys, inhomogeneous reionization, and dark energy

description: We examine the effect of inhomogeneous reionization on the galaxy power spectrum and the consequences for probing dark energy. To model feedback during reionization, we apply an ansatz setting the galaxy overdensity proportional to the underlying ionization field. Thus, inhomogeneous reionization may leave an imprint in the galaxy power spectrum. We evolve this imprint to low redshift and use the Fisher-matrix formalism to assess the effect on parameter estimation. We show that a combination of low- (z=0.3) and high- (z=3) redshift galaxy surveys can constrain the size of cosmological HII regions during reionization. This imprint can also cause confusion when using baryon oscillations or other features of the galaxy power spectrum to probe the dark energy. We show that when bubbles are large, and hence detectable, our ability to constrain w can be degraded by up to 50%. When bubbles are small, the imprint has little or no effect on measuring dark-energy parameters.

description: In tasks such as tracking, time-series data inevitably carry missing observations. While traditional tracking approaches can handle missing observations, recurrent neural networks (RNNs) are designed to receive input data in every step. Furthermore, current solutions for RNNs, like omitting the missing data or data imputation, are not sufficient to account for the resulting increased uncertainty. Towards this end, this paper introduces an RNN-based approach that provides a full temporal filtering cycle for motion state estimation. The Kalman filter inspired approach, enables to deal with missing observations and outliers. For providing a full temporal filtering cycle, a basic RNN is extended to take observations and the associated belief about its accuracy into account for updating the current state. An RNN prediction model, which generates a parametrized distribution to capture the predicted states, is combined with an RNN update model, which relies on the prediction model output and the current observation. By providing the model with masking information, binary-encoded missing events, the model can overcome limitations of standard techniques for dealing with missing input values. The model abilities are demonstrated on synthetic data reflecting prototypical pedestrian tracking scenarios.

description: We study the breaking of reciprocity in non-Hermitian coupled photonic waveguides by the simultaneous action of the nonlinear effect of saturable absorption, and the presence of exceptional points. The nonlinear response of such a system is studied in depth, giving physical insight into the operational principles and fundamental limitations, while producing analytical and semi-analytical results for the transmission and nonreciprocal intensity range. We numerically validate the theoretical results and assess important performance metrics for the nonreciprocal operation of such a device. This novel class of passive non-resonant devices can offer on-chip broadband nonreciprocal operation, making them potentially very important for high-speed applications.

description: Well-known (spinless) fermionic qubits may need more subtle consideration in comparison with usual (spinful) fermions. Taking into account a model with local fermionic modes, formally only the 'occupied' states |1> could be relevant for antisymmetry with respect to particles interchange, but 'vacuum' state |0> is not. Introduction of exchange rule for such fermionic qubits indexed by some 'positions' may look questionable due to general super-selection principle. However, a consistent algebraic construction of such 'super-indexed' qubits is presented in this work. Considered method has some relation with construction of super-spaces, but it has some differences with standard definition of supersymmety sometimes used for generalizations of qubit model.

Polarization diagnostics of proton beams in solar flares

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We review the problem of proton beam bombardment of solar chromosphere considering the self-consistent NLTE polarized radiation transfer in hydrogen lines. Several observations indicate a linear polarization of the H-alpha line of the order of 5% or higher and preferentially in radial direction. This polarization is often explained as anisotropic collisional excitation of the n=3 level by vertical proton beams. Our calculations indicate that deceleration of the proton beam with initial power-law energy distribution together with increased electron and proton densities in the H-alpha forming layers lead to a negligible line polarization. Thus the proton beams seem not to be a good candidate for explanation of the observed polarization degree. On the other hand, the effect of electric return currents could perhaps provide a better explanation of the observed linear polarization. We report the new calculations of this effect.

description: It has been established that "hard probes", observables involving high-momentum transfer, provide useful tools for studying the hot, dense medium created in nucleus-nucleus collisions at RHIC. The nuclear modification factor, azimuthal correlations, direct photon production, as well as the dependence of the nuclear modificaton factor on centrality and angle with respect to the reaction plane are critical for understanding the early dynamics of such heavy-ion collisions. We will review recent results from PHENIX for particle production at high-pT and discuss their implications.

We use simulated LSST data and existing real observations to test the estimations of the physical properties of galaxies, such as star formation rate (SFR), stellar mass ($M_{star}$), and dust luminosity ($L_{dust}$). We focus on normal star-forming galaxies, as they form the majority of the galaxy population in the universe and therefore are more likely to be observed by the LSST. We perform a simulation of LSST observations and uncertainties of 50,385 real galaxies within redshift range $0

International trade and legal modernization: effects of Mexico’s membership in the North American Free Trade Agreement
Creators: name: Beteta, Armando F.
Publisher: name: University of British Columbia
Year: 2008

description: The North American Free Trade Agreement, signed by the United States, Canada, and Mexico in December 17, 1992, establishes an important example of a Common Market which includes the participation of both developing and developed nations. However, the fact that a less developed nation is included in this "first world" economic enterprise has created uncertainty regarding the Agreement's possibilities of success, since severe economic, political, and legal discrepancies separate the Parties. Legislation usually reflects a nation's economic, political and cultural, characteristics. Therefore, by comparing different legal systems, one is able to observe the discrepancies existing among the economics, cultures and politics of nations. The main purpose of this thesis is to find out if NAFTA is a proper instrument for the elimination of differences between developed and developing countries and; if this is the case, examining the means used to achieve such purpose. This thesis consists of four chapters. The theoretical approach of the thesis will be developed in the first two, where an overview of the theories of free trade and dependency will be presented. The problem of how to regulate divergent economies under an international agreement will be approached in the last two chapters by making (in Chapter Three) a legal comparison between NAFTA and the European Economic Community; and by addressing (in Chapter Four) particular legal disparities among North American nations in the area of intellectual and industrial property, and their treatment under NAFTA. Benefits of free trade have encourage nations to forming international economic blocs, which will improve their competitiveness at both the domestic and international level. Less developed nations which are interested in participating in this new economic trend, have engaged in legal reform and trade liberalization, in order to satisfy the pressures and meet the standards of industrialized nations. NAFTA has proven to be an efficient instrument for the homogeneization of rules. Because, especially in the branch of Intellectual Property, the Agreement helps eliminate most differences between the Parties in establishing clear and unified principles and encouraging domestic legal reform in Mexico.
Prolegomena to a postmodern theory of law
Creators: name: Braithwaite, Murray J.
Publisher: name: University of British Columbia
Year: 2008

description: Research in artificial intelligence and law has stalled because it presumes the model of legal reasoning asserted by legal positivism. An adequate model of legal reasoning must relate legal rules to social goals and must respond to critical perspectives. No existing legal theory accomplishes these tasks. This thesis asserts that postmodernism overcomes current difficulties in constructing an adequate model of legal reasoning. My methodology is to apply results from the sciences of chaos and complex adaptive systems to derive the elements of postmodernism from a mathematical perspective. This shows how systems can spontaneously construct knowledge and improve without assuming the possibility of perfect knowledge about social systems. I show how law behaves as a complex adaptive system and argue that legal reasoning shows the type of knowledge-building accomplished by complex adaptive systems. This implies limitations on what legal reasoning can attempt to accomplish and provides criteria to criticize existing legal theories. Social orders emerge from the concurrent behaviour of many individuals. The utility of social orders for society implies that there is value in individuals behaving according to rules. An important implication of chaos theory is that our knowledge about social orders must in principle remain imprecise. We can model social orders but the models must employ fuzzy concepts that are correlated or causally related probabilistically. The fundamental task of legal reasoning is to mediate the requirements of conflicting social orders. Some social orders are undesirable, so legal reasoning must include a strategy to expose ideology and decadence. When law-makers choose between alternative rules, they must consider the possible impact of each proposed rule upon desirable social orders. In a hard case, a law-maker must choose to impair either of two social orders. Since knowledge about the functioning of the social orders is fuzzy and probabilistic, the law-maker must model the social orders in terms of fuzzy instrumental goals and estimate the probable degree of impairment to the goals by each of the alternative rule possibilities. This thesis confirms and advances the "deep-structure" theory of jurisprudence and its application to legal expert systems.

description: We report a strong experimental evidence of the optical anisotropy in a CdTe-based microcavity: the polarization of light is pinned to one of the crystallographic axes independently on the polarization of the excitation. The polarization degree depends strongly on the excitation power, reaching almost 100 % in the stimulated regime. The relaxation time of the polarization is about 1 ns. We argue that all this is an effect of a splitting of the polariton doublet at k=0. We consider different sources for the splitting and conclude that the most likely one is optical birefringence in the mirrors and/or the cavity.

description: Quantum spin-liquid van der Waals magnets such as TaS$_2$, TaSe$_2$, and RuCl$_3$ provide a natural platform to explore new exotic phenomena associated with spinon physics, whose properties can be controlled by exchange proximity with ferromagnetic insulators such as CrBr$_3$. Here we put forward a twisted van der Waals heterostructure based on a quantum spin-liquid bilayer encapsulated between ferromagnetic insulators. We demonstrate the emergence of spinon flat bands and topological spinon states in such heterostructure, where the emergence of a topological gap is driven by the twist. We further show that the spinon bandstructure can be controlled via exchange proximity effect to the ferromagnetic leads. We finally show how by combining small magnetic fields with tunneling spectroscopy, magnetically encapsulated heterostructures provide a way of characterizing the nature of the quantum spin-liquid state. Our results put forward twisted quantum spin-liquid bilayers as potential platforms for exotic moire spinon phenomena, demonstrating the versatility of magnetic van der Waals heterostructures.

description: The DSHARP survey evidenced the ubiquity of substructure in the mm dust distribution of large, bright protoplanetary discs. Intriguingly, these datasets have yet higher resolution information that is not recovered in a CLEAN image. We first show that the intrinsic performance of the CLEAN algorithm is resolution-limited. Then analyzing all 20 DSHARP sources using the 1D, super-resolution code Frankenstein (frank), we accurately fit the 1D visibilities to a mean factor of 4.3 longer baseline than the Fourier transform of the CLEAN images and a factor of 3.0 longer baseline than the transform of the CLEAN component models. This yields a higher resolution brightness profile for each source, identifying new substructure interior to 30 au in multiple discs; resolving known gaps to be deeper, wider, and more structured; and known rings to be narrower and brighter. Across the survey, high contrast gaps are an average 14% wider and 44% deeper in the frank profiles relative to CLEAN, and high contrast rings are an average 26% narrower. Categorizing the frank brightness profiles into trends, we find that the relative scarcity of features interior to 30 au in the survey's CLEAN images is an artifact of resolving power, rather than an intrinsic rarity of inner disc (or compact disc) substructure. Finally the rings in the frank profiles are narrower than the previously inferred deconvolved widths, indicating smaller alpha / St ratios in the local gas disc.

description: We consider a generalization of the Jarzynski relation to the case where the system interacts with a bath for which the temperature is not kept constant but can vary during the transformation. We suggest to use this relation as a replacement to the thermodynamic perturbation method or the Bennett method for the estimation of the order-order surface tension by Monte Carlo simulations. To demonstrate the feasibility of the method, we present some numerical data for the 3D Ising model.

Renormalization-group techniques for single-field inflation in primordial cosmology and quantum gravity

description: We study inflation as a "cosmic" renormalization-group flow. The flow, which encodes the dependence on the background metric, is described by a running coupling $α$, which parametrizes the slow roll, a de Sitter free, analytic beta function and perturbation spectra that are RG invariant in the superhorizon limit. Using RG invariance as a guiding principle, we classify the main types of flows according to the properties of their spectra, without referring to their origins from specific actions or models. Novel features include spectra with essential singularities in $α$ and violations of the relation $r+8n_{\text{t}}=0$ to the leading order. Various classes of potentials studied in the literature can be described by means of the RG approach, even when the action includes a Weyl-squared term, while others are left out. In known cases, the classification helps identify the models that are ruled out by data. The RG approach is also able to generate spectra that cannot be derived from standard Lagrangian formulations.

description: We demonstrate a conceptually new mechanism for sub-wavelength focusing at optical frequencies based upon the use of nano-hole quasi-periodic arrays in metal screens. Using coherent illumination at 660 nm and scanning near-field optical microscopy, ~290 nm "hot spots", were observed at a distance of ~12.5 mkm from the array. Even smaller hot-spots of about 200 nm in waist were observed closer to the plane of the array.
Screening in (d+s)-wave superconductors: Application to Raman scattering

description: We study the polarization-dependent electronic Raman response of untwinned YBa$_2$Cu$_3$O$_{7-δ}$ superconductors employing a tight-binding band structure with anisotropic hopping matrix parameters and a superconducting gap with a mixing of $d$- and s-wave symmetry. Using general arguments we find screening terms in the $B^{\}_{1g}$ scattering channel which are required by gauge invariance. As a result, we obtain a small but measurable softening of the pair-breaking peak, whose position has been attributed for a long time to twice the superconducting gap maximum. Furthermore, we predict superconductivity-induced changes in the phonon line shapes that could provide a way to detect the isotropic s-wave admixture to the superconducting gap.

description: We measure the galaxy 2- and 3-point correlation functions at $z=[0.5,0.7]$ and $z=[0.7, 0.9]$, from the final data release of the VIPERS survey (PDR2). We model the two statistics including a nonlinear 1-loop model for the 2-point function and a tree-level model for the 3-point function, and perform a joint likelihood analysis. The entire process and nonlinear corrections are tested and validated through the use of the 153 highly realistic VIPERS mock catalogues, showing that they are robust down to scales as small as 10 $h^{-1} \, \mathrm{Mpc}$. The mocks are also adopted to compute the covariance matrix that we use for the joint 2- and 3-point analysis. Despite the limited statistics of the two (volume-limited) sub-samples analysed, we demonstrate that such a combination successfully breaks the degeneracy existing at 2-point level between clustering amplitude $σ_8$, linear bias $b_1$ and the linear growth rate of fluctuations $f$. For the latter, in particular, we measure $f(z=0.61)=0.64^{+0.55}_{-0.37}$ and $f(z=0.8)=1.0\pm1.0$, while the amplitude of clustering is found to be $σ_8(z=0.61)=0.50\pm 0.12$ and $σ_8(z=0.8)=0.39^{+0.11}_{-0.13}$. These values are in excellent agreement with the extrapolation of a Planck cosmology.

description: Σκοπός της εργασίας ήταν η κατάθεση της ομολογουμένως εξαιρετικής θεολογικής εμπειρίας και γνώσης του Αγίου Γρηγορίου του Θεολόγου. Στο παρόν πόνημα επικεντρωθήκαμε στο δόγμα της Χριστολογίας και την ανάγκη περιγραφής αυτής της αλήθειας, απέναντι στην χριστολογική αίρεση του Απολινάριου. Αναφέροντας παράλληλα και τις άλλες πτυχές των δογματικών όρων της Εκκλησίας μας, καθότι είναι δεδομένο, ότι όλες οι δογματικές αλήθειες είναι οργανικά εξαρτημένες μεταξύ τους. Επομένως αποδώσαμε στα επιτρεπτά όρια του κειμένου την ερμηνεία και περιγραφή των αληθειών αυτών, μέσα από την οπτική και την εμπειρία του Αγίου Γρηγορίου. Εξετάζοντας πρώτα τον βίο του Αγίου, τον προσεγγίσαμε κάτω από τους θεολογικούς προβληματισμούς που επηρέασαν τις επιλογές του. Στη συνέχεια καταθέσαμε τον βίο του Απολινάριου και την εσφαλμένη ερμηνεία που κάνει στο χριστολογικό ζήτημα. Και αφού θίξαμε τον πατερικό τρόπο ερμηνείας της δημιουργίας του κόσμου και της πτώσης του ανθρώπου, ασχοληθήκαμε επισταμένως με το μυστήριο της ενανθρώπησης του Χριστού, όπως αυτή αποδίδεται από τον μοναδικό αυτό Πατέρα της Ορθόδοξης Εκκλησίας.
description: The aim of the current study was to illustrate the widely acknowledged, exceptional theological experience and knowledge of Saint Gregory the Theologian. In particular, the focus of this investigation comprised the doctrine of Christology and the necessity to highlight the truth involved, in sharp contrast to the Christological heresy represented by Apollinaris of Laodicea. Specifically, our approach had been comparative, examining and evaluating the various aspects of the associated doctrinal terminology, as expressed by the Greek Orthodox Church, aspects which are integrally interrelated and interdependent to each other. As a result, we described and interpreted the theological truth, stemming from the original text and via the perspective and experience of Saint Gregory. More precisely, firstly, we concentrated to the life of Saint Gregory and the most important theological problematizations, which had affected his theological modus operandi. Consequently, we represented the live of Apollinaris of Laodicea and his erroneous interpretation of the Christological issue. Moreover, important observations had been addressed regarding the way in which the patristic fathers approached and interpreted the creation of the world and the fall of man. Finally, we meticulously engaged with the mystery of the human nature of Jesus Christ (incarnation), as approached and demonstrated by such a unique patristic father of the Greek Orthodox Church.
On the electromagnetic momentum of static charge and steady current distributions

description: Faraday's and Furry's formulas for the electromagnetic momentum of static charge distributions combined with steady electric current distributions are generalised in order to obtain full agreement with Poynting's formula in the case where all fields are of class C^1, i.e., continuous and continuously differentiable, and the integration volume is of finite or infinite extent. These three formulas are further generalised to the case where singularities are allowed to exist at isolated points in the fields, and at surfaces separating domains in which the distributions are of class C^1. Applications are made to electric and magnetic, point-like and finite dipolar systems, with an emphasis on the impact of singularities on the magnitude and location of the electromagnetic momentum.
