description: The interface and electronic structure of thin (~20-74 nm) Co3O4(110) epitaxial films grown by oxygen-assisted molecular beam epitaxy on MgAl2O4(110) single crystal substrates have been investigated by means of real and reciprocal space techniques. As-grown film surfaces are found to be relatively disordered and exhibit an oblique low energy electron diffraction (LEED) pattern associated with the O-rich CoO2 bulk termination of the (110) surface. Interface and bulk film structure are found to improve significantly with post-growth annealing at 820 K in air and display sharp rectangular LEED patterns, suggesting a surface stoichiometry of the alternative Co2O2 bulk termination of the (110) surface. Non-contact atomic force microscopy demonstrates the presence of wide terraces separated by atomic steps in the annealed films that are not present in the as-grown structures; the step height of ~ 2.7 A corresponds to two atomic layers and confirms a single termination for the annealed films, consistent with the LEED results. A model of the (1 * 1) surfaces that allows for compensation of the polar surfaces is presented.

description: We report on the results of new simulations of near-infrared (NIR) observations of the Sagittarius A* (Sgr A*) counterpart associated with the super-massive black hole at the Galactic Center. The observations have been carried out using the NACO adaptive optics (AO) instrument at the European Southern Observatory's Very Large Telescope and CIAO NIR camera on the Subaru telescope (13 June 2004, 30 July 2005, 1 June 2006, 15 May 2007, 17 May 2007 and 28 May 2008). We used a model of synchrotron emission from relativistic electrons in the inner parts of an accretion disk. The relativistic simulations have been carried out using the Karas-Yaqoob (KY) ray-tracing code. We probe the existence of a correlation between the modulations of the observed flux density light curves and changes in polarimetric data. Furthermore, we confirm that the same correlation is also predicted by the hot spot model. Correlations between intensity and polarimetric parameters of the observed light curves as well as a comparison of predicted and observed light curve features through a pattern recognition algorithm result in the detection of a signature of orbiting matter under the influence of strong gravity. This pattern is detected statistically significant against randomly polarized red noise. Expected results from future observations of VLT interferometry like GRAVITY experiment are also discussed.

description: Some field theoretical aspects, such as the effective action and Schwinger pair production, are critically reviewed in strong QED. The difference of the boundary conditions on the solutions of the field equation is discussed to result in the effective action both in the Coulomb and time-dependent gauge. Finally, the apparent spin-statistics inversion is also discussed, where the WKB action for bosons (fermions) works well for fermion (boson) pair-production rate.

Lyman "bump" galaxies - I. Spectral energy distribution of galaxies with an escape of nebular Lyman continuum
Creators: name: Inoue, Akio K.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: It is essential to know galactic emissivity and spectrum of Lyman continuum (LyC) in order to understand the cosmic reionization. Here we consider an escape of nebular LyC from galaxies and examine the consequent spectral energy distribution. It is usually assumed that hydrogen nebular LyC mostly produced by bound-free transitions is consumed within photo-ionized nebulae (so-called "on-the-spot" approximation). However, an escape of the continuum should be taken into account if stellar LyC escapes from galaxies through "matter-bounded" nebulae. We show that the escaping hydrogen bound-free LyC makes a strong bump just below the Lyman limit. Such a galaxy would be observed as a Lyman "bump" galaxy. This bump results from the radiation energy re-distribution of stellar LyC by nebulae. The strength of the bump depends on electron temperature in nebulae, escape fraction of stellar and nebular LyC, hardness of stellar LyC (i.e. metallicity, initial mass function, age and star formation history), and IGM attenuation. We can use the bump to find very young ($\sim1$ Myr), massive ($\sim100$ $M_\odot$), and extremely metal-poor (or metal-free) stellar populations at $z<4$. Because of the bump, 900 Å-to-1500 Åluminosity density ratio (per Hz) becomes maximum (2--3 times larger than the stellar intrinsic ratio) when about 40% of the stellar LyC is absorbed by nebulae. The total number of escaping LyC photons increases due to the escape of nebular LyC but does not exceed the stellar intrinsic one. The radiation energy re-distribution by nebulae reduces the mean energy of escaping LyC only by $\approx10$% relative to that of stellar LyC. Therefore, the effect of the escape of nebular LyC on the reionization process may be small.

Dynamics of Black Hole Pairs II: Spherical Orbits and the Homoclinic Limit of Zoom-Whirliness

description: Spinning black hole pairs exhibit a range of complicated dynamical behaviors. An interest in eccentric and zoom-whirl orbits has ironically inspired the focus of this paper: the constant radius orbits. When black hole spins are misaligned, the constant radius orbits are not circles but rather lie on the surface of a sphere and have acquired the name "spherical orbits". The spherical orbits are significant as they energetically frame the distribution of all orbits. In addition, each unstable spherical orbit is asymptotically approached by an orbit that whirls an infinite number of times, known as a homoclinic orbit. A homoclinic trajectory is an infinite whirl limit of the zoom-whirl spectrum and has a further significance as the separatrix between inspiral and plunge for eccentric orbits. We work in the context of two spinning black holes of comparable mass as described in the 3PN Hamiltonian with spin-orbit coupling included. As such, the results could provide a testing ground of the accuracy of the PN expansion. Further, the spherical orbits could provide useful initial data for numerical relativity. Finally, we comment that the spinning black hole pairs should give way to chaos around the homoclinic orbit when spin-spin coupling is incorporated.

The jurisprudence of the International Court of Justice : customary international law; state sovereignty; and the domestic jurisdiction
Creators: name: Dogra, H.K.
Publisher: name: University of British Columbia
Year: 2011

description: Purpose and Limits of the Present Study. International litigation is primarily concerned with finding a solution for the conflicting and contradictory claims of the disputant states who have different notions of justice for their acts and omissions at the international level. This problem becomes more acute when one party asserts its right against the other, and, in the absence of any treaty or convention, tries to establish and prove the existence of such right, on the basis of long usage, practice or custom, recognized as such by the civilized nations of the international community. The International Court of Justice, like its predecessor, the Permanent Court of International Justice, had to face those problems in a number of cases brought before it, and it succeeded, to a great extent, in solving those complicated problems, and, by crystallizing those rudimentary rules of customary law, which in the past had been a source of confusion for the international jurists, has made important contributions to the development of international law. It is the purpose of the present study to analyze the jurisprudence of the Court and, to find those principles of customary international law that the Court has applied for arriving at a particular decision. The approach is basically expository, and is confined to scrutinize that volume of authority, which the Court has produced on "international custom, as evidence of a general practice accepted as law."¹ Within this limited range it was thought desirable not to ignore the fundamental questions relating to state sovereignty and "domestic jurisdiction", which present-' various problems in international adjudication. Since the object of the present thesis is to extract, assemble, and evaluate the nature of those principles which the Court enunciated in its Judgments, it was found necessary to draw upon the individual opinions of the dissenting Judges, or, the separate opinions of those who concurred in the operative part of the Judgment, but, gave different reasons for arriving at the same conclusion, because it has been said that: "A dissent in a court of last resort is an appeal to the broadening spirit of the law, to the intelligence of a future day where a later decision may possibly correct the error into which the dissenting judge believes the court to have been betrayed.”¹ 1 Art. 38 (1) (b) of the Statute of the Court. 1 Charles Evans Hughes, U.S. Supreme Court 68 (1928) (quoted by Runz, "The Nottebohm Judgment (second phase)," 514 AJIL (I960), p.. 539; see however, Lauterpacht, The Development of International Law by the International Court of Justice, Stevens, London, 1958, pp. 66-7).

description: The twistor space of the sphere S^{2n} is an isotropic Grassmannian that fibers over S^{2n}. An orthogonal complex structure on a subdomain of S^{2n} (a complex structure compatible with the round metric) determines a section of this fibration with holomorphic image. In this paper, we use this correspondence to prove that any finite energy orthogonal complex structure on R^6 must be of a special warped product form, and we also prove that any orthogonal complex structure on R^{2n} that is asymptotically constant must itself be constant. We will also give examples defined on R^{2n} which have infinite energy, and examples of non-standard orthogonal complex structures on flat tori in complex dimension three and greater.

description: This study examined absolute and relative judgment accuracies of German early childhood (EC) teachers with respect to the mathematical skills of the children under their supervision. The two types of judgment accuracies are crucial prerequisites for pacing activities in EC education and offering differentiated educational activities adapted to individual skill levels of children. Data from 39 EC teachers and 268 children were analyzed using multilevel modeling. Teachers rated the skills of children on a structured observation instrument (“Kinder Diagnose Tool,” KiDiT). Children were assessed on their mathematical skills with a standardized test (“Mathematische Basiskompetenzen im Kindesalter,” MBK-0). On average, 65% of the variation in judgments of teachers on the KiDiT could be explained by MBK-0 scores of children, which suggest that teachers are—on average—able to rank children within their groups. Teachers were also able to judge the mathematical level of skills of children as assessed by the MBK-0. Neither mathematical content knowledge (MCK) of teachers nor their mathematics pedagogical content knowledge (MPCK) or general pedagogical knowledge (GPK) moderated the relationship between judgments of teachers and test scores of children or the relationship between the level of the judgments and the level of test scores. Conclusions for future research and practice are drawn.
Involutions of the Mathieu groups
Creators: name: Fraser, Richard Evan James
Publisher: name: University of British Columbia
Year: 2011

description: The five Mathieu permutation groups M₁₁, M₁₂M₂₂,M₂₃ and M₂₄ are constructed and the involutions (elements of order two) of these groups are classified according to the number of letters they fix. It is shown that in M₁₂ ah involution fixes no letters or four letters, while in M₂₄ an involution fixes zero or eight letters. It is also shown that in each of the Mathieu groups, all the irregular involutions are conjugate and that in M₁₂ all the regular involutions are conjugate. The orders of the centralizers of the involutions are calculated and it is shown that no regular involution lies in the centre of a 2-Sylow subgroup. Most of the results are obtained by calculating directly the form a permutation must take in order to have a certain property and then finding one or all the permutations of this form.

description: Detailed geological mapping of the Urtier Valley in the Western Alps allowed to realize a new geological map 1:10.000 in scale. In the mapped area, a complete nappe stack of the axial part of the Alpine belt crops out. The study focused on the two units derived from the Piemonte-Ligurian oceanic domain, Broillot and Bardonney units, for which, in addition to the classic petrographic and structural considerations, a lithostratigraphic approach was applied. The lithostratigraphic approach, combined with structural analysis, led to reconstruct a nappe stacking significantly different from that generally proposed for the Western Alps. In the Urtier Valley in fact, the eclogite facies units are at the top of the nappe pile, overlapped on the blueschist facies units. This anomalous stacking order could be explained by interpreting the study area as an inverted limb of a regional fold with the eclogite facies units at the core.

description: The quantum dynamics of one-dimensional bosonic Josephson junctions with attractive and repulsive interparticle interactions is studied using the Bose-Hubbard model and by numerically-exact computations of the full many-body Hamiltonian. A symmetry present in the Bose-Hubbard Hamiltonian dictates an equivalence between the evolution in time of attractive and repulsive Josephson junctions with attractive and repulsive interactions of equal magnitude. The full many-body Hamiltonian does not possess this symmetry and consequently the dynamics of the attractive and repulsive junctions are different.

description: Abstract

All researchers emphasize the need for an individual approach to teaching students, the importance of a unified educational strategy for universities as the main condition for successful work with students. However, there are still no generalizing scientific and pedagogical works that holistically reveal the process of using the technology of student-centered learning. The social significance of student development and the analysis of the state of scientific development of this process determined the choice of the problem of this study, which is to determine how to use technologies for student-centered learning in university setting. The purpose of the article is determined by the need to identify the conditions for using the technology of student-centered learning in the conditions of a modern university.

The black hole mass, Eddington ratio, and M_bh-σ_[O III] relation in young radio galaxies

description: The BH masses and the Eddington ratios for a sample of 65 young radio galaxies [27 GPS and 38 CSS sources] are estimated by various methods. We find that the average BH mass of these young radio galaxies is =8.3, which is less than that of radio loud QSOs and low redshift radio galaxies(=9.0). The CSS/GPS sources have relatively high Eddington ratios with average ratio =-0.56, which are similar to those of narrow line Seyfert 1 galaxies (NLS1s). It suggests that the CSS/GPS sources may not only be in the early stage of radio activities, but also in the early stage of their accretion activities. We find that the young radio galaxies as a class deviate systematically from the M_bh-σ_* relation defined by nearby inactive galaxies, when using σ_[O III] as a surrogate for the stellar velocity dispersion σ_*. There is no significant correlation between the deviation of the [O III] emission line width, $Δσ$=σ_[O III]-σ_[pred], and the jet/accretion power, where σ_[pred] are calculated from the Tremaine et al. relation using the estimated BH masses. However, we find that the deviation $Δσ$ in young radio galaxies is well correlated with the Eddington ratio, and this correlation is found to be similar to that of radio quiet AGN (QSOs/NLS1s) where the radio jet is absent or weak. We suggest that the accretion activities may still play an important role in shaping the kinematics of [O III] narrow line in these young radio galaxies.

description: We introduce a new operation on skew diagrams called composition of transpositions, and use it and a Jacobi-Trudi style formula to derive equalities on skew Schur Q-functions whose indexing shifted skew diagram is an ordinary skew diagram. When this skew diagram is a ribbon, we conjecture necessary and sufficient conditions for equality of ribbon Schur Q-functions. Moreover, we determine all relations between ribbon Schur Q-functions; show they supply a Z-basis for skew Schur Q-functions; assert their irreducibility; and show that the non-commutative analogue of ribbon Schur Q-functions is the flag h-vector of Eulerian posets.

description: We present a new survey strategy to discover and study high redshift Type Ia supernovae (SNe Ia) using the Hubble Space Telescope (HST). By targeting massive galaxy clusters at 0.90.95, nine of which were in galaxy clusters. This strategy provides a SN sample that can be used to decouple the effects of host galaxy extinction and intrinsic color in high redshift SNe, thereby reducing one of the largest systematic uncertainties in SN cosmology.

Extension of Airy's equation
Creators: name: Headley, Velmer Bentley
Publisher: name: University of British Columbia
Year: 2011

description: We consider the differential equation d²u/dz² - zⁿu = 0 (z, u complex variables; n a positive integer), which is the simplest second order ordinary differential equation with a turning point of order n. The solutions which we study, herein called Aռ functions, are generalizations of Airy functions. Most of their properties are then deduced from those of related Bessel functions of order [formula omitted], but in the discussion of the zeros in section 3, results are deduced directly from the differential equation. It is easy to see that the Aռ functions are special cases of functions studied by Turrittin [9]. The relation of the former to Bessel functions, however,, enables us to use methods not available in [9] to obtain uniform asymptotic representations for large z. We obtain new results on the distribution of the zeros which extend a property [6] of Airy functions, that is, of A₁functions,, to all positive integers n. A similar remark applies to bounds [8] for Airy functions and their reciprocals.

description: The continuous wavelet transform is adapted to account for signal truncation through renormalization and by modifying the shape of the analyzing window. Comparison is made of the instant and integrated wavelet power with previous algorithms. The edge adapted and renormalized admissible wavelet transforms are used to estimate the level of solar magnetic activity from the sunspot record. The solar activity is compared to Oerlemans' temperature reconstruction and to the Central England Temperature record. A correlation is seen for years between 1610 and 1990, followed by a strong deviation as the recently observed temperature increases.

Essentsiaalse hüpertensiooniga haigetel on mikroalbuminuuria ilmumine märgiks, et veresoonkonna olukord halveneb progresseeruvalt ning võib areneda nefroskleroos. Hiljuti tehtud uuringutel on leitud, et mikroalbuminuuria on sage ka üldrahvastikus. Seetõttu on soovitatav suure kardiovaskulaarse riskiga inimestel mikroalbuminuuria sõeluurimine ja vasoprotektiivse ravi määramine.

description: We present new evolutionary synthesis models for Simple Stellar Populations for a wide range of ages and metallicities. The models are based on the Padova isochrones. The core of the spectral library is provided by the medium resolution Lejeune et al. atmosphere models. These spectra are complemented by NLTE atmosphere models for hot stars that have an important impact in the stellar cluster's ionizing spectra: O, B and WR stellar spectra at the early ages, and spectra of post-AGB stars and planetary nebulae, at intermediate and old ages. At young ages, our models compare well with other existing models but we find that, the inclusion of the nebular continuum, not considered in several other models, reddens significantly the integrated colours of very young stellar populations. This is consistent with the results of spectral synthesis codes particularly devised for the study of starburst galaxies. At intermediate and old ages, the agreement with literature model is good and, in particular, we reproduce well the observed colours of star clusters in LMC. Given the ability to produce good integrated spectra from the far-UV to the infrared at any age, we consider that our models are particularly suited for the study of high redshift galaxies. These models are available on the web site {http://www.fractal-es.com/SEDmod.htm} and also through the Virtual Observatory Tools on the PopStar server.

A Dynamic Boundary Guarding Problem with Translating Targets

Publisher: name: arXiv
Year: 2009

description: We introduce a problem in which a service vehicle seeks to guard a deadline (boundary) from dynamically arriving mobile targets. The environment is a rectangle and the deadline is one of its edges. Targets arrive continuously over time on the edge opposite the deadline, and move towards the deadline at a fixed speed. The goal for the vehicle is to maximize the fraction of targets that are captured before reaching the deadline. We consider two cases; when the service vehicle is faster than the targets, and; when the service vehicle is slower than the targets. In the first case we develop a novel vehicle policy based on computing longest paths in a directed acyclic graph. We give a lower bound on the capture fraction of the policy and show that the policy is optimal when the distance between the target arrival edge and deadline becomes very large. We present numerical results which suggest near optimal performance away from this limiting regime. In the second case, when the targets are slower than the vehicle, we propose a policy based on servicing fractions of the translational minimum Hamiltonian path. In the limit of low target speed and high arrival rate, the capture fraction of this policy is within a small constant factor of the optimal.

Topological diffuse semigroups (systems with a stochastic product).
Creators: name: Armstrong, William Ward
Publisher: name: University of British Columbia
Year: 2011

description: A generalization of the concept of a locally compact Hausdorff topological semigroup and its associated convolution semigroup of regular Borel probabilities is defined and studied. Let S be a locally compact Hausdorff space, ℬ be the σ-algebra of all Borel subsets of S , and ℘ be the set of all regular Borel probability measures on S. Suppose P*Q is an associative binary operation defined for P, Q in ℘ with values in ℘ which is affine and continuous (in the topology of weak convergence) in each variable P, Q separately. Then the structure (S,ℬ,℘,*) so defined is termed a topological diffuse semigroup. S is considered to be embedded in ℘ as the set of all point-masses. If the operation * is restricted to S , then S will not be a semigroup in general, for the product x*y for x, y in S will be a probability measure on S . If this is a point-measure for all x, y in S , then S will be a semigroup, and ℘ will be the usual convolution semigroup of regular probabilities. Topological diffuse semigroups are also generalizations of the "generalized convolutions" studied by K. Urbanik. In order to study the structure of topological diffuse semigroups, a product of subsets of S is defined: EF is defined to be the closure of the union of the supports of the measures x*y for x in E and y in F . A right ideal R is then defined to be a subset of S such that RS is contained in R . Left ideals and two-sided ideals are defined similarly. S is defined to be a diffuse group if {X}S = S{x} = S for all x in S . Using these concepts one can partially carry over to compact diffuse semigroups the Rees-Suschkewitsch structure theorem. There are interesting deviations from semigroup behaviour however. For example, it may happen that the union of the minimal right ideals is merely dense in the minimal two-sided ideal of a compact diffuse semigroup. If the minimal one-sided ideals of a compact diffuse semigroup are assumed to be open, then the minimal two-sided ideal is the disjoint union of the finite number of minimal right (or left) ideals, and also the finite disjoint union of diffuse groups. Idempotent probability measures are studied and in some cases expressed in terms of "normed Haar measures" on compact diffuse groups. A limit theorem of Rosenblatt for Cesàro averages of *-powers is generalized to compact diffuse semigroups with jointly continuous multiplication. As an application of the theory of topological diffuse semigroups, it is shown that the "generalized convolutions" of Urbanik are jointly continuos operations.

description: For singular perturbation problems in dynamical systems, various appropriate singular perturbation methods have been proposed to eliminate secular terms appearing in the naive expansion. For example, the method of multiple time scales, the normal form method, center manifold theory, the renormalization group method are well known. In this paper, it is shown that all of the solutions of the reduced equations constructed with those methods are exactly equal to sum of the most divergent secular terms appearing in the naive expansion. For the proof, a method to construct a perturbation solution which differs from the conventional one is presented, where we make use of the theory of Lie symmetry group.
