Iterative algorithms for the inversion of matrices on digital computers
Creators: name: Harris, Arthur Dorian Shaw
Publisher: name: University of British Columbia
Year: 2011

description: After a general discussion of matrix norms and digital operations, matrix inversion procedures based on power series expansions are examined. The general class of methods of which the Diagonal and Gauss-Seidel iterations are illustrative is studied in some detail with bounds for the error matrix being obtained assuming, both exact and digital operations. The concept of the condition of a matrix and its bearing on iterative inversion procedures is looked into. A similar derivation and examination is then made for Hotelling's algorithm. Hotelling's iteration is further examined with a view to modifying it. Higher-order formulae are obtained and criticized and a new variation of the algorithm called the Optimized Hotelling method is derived and commented on. Some schemes for constructing initial approximations in connection with Hotelling's iteration (and similar methods) are discussed and a new modification of a procedure proposed by Berger and Saibel is constructed. The final part of the thesis discusses a class of finite-step iterative inversions based on an identity of Householder's. Three members of the class, namely Jordan-type Completion, the Symmetric method and the Quasi-optimum method are defined and briefly discussed. The Quasi-optimum method is then examined in further detail and some of its properties derived for the special case with the unit matrix for an initial approximation.

description: We suggest an alternative mathematical model for the massless neutrino. Consider an elastic continuum in 3-dimensional Euclidean space and assume that points of this continuum can experience no displacements, only rotations. This framework is a special case of the so-called Cosserat theory of elasticity. Rotations of points of the continuum are described by attaching to each point an orthonormal basis which gives a field of orthonormal bases called the coframe. As the dynamical variables (unknowns) of our theory we choose a coframe and a density. We write down a potential energy which is conformally invariant and then incorporate time in the standard Newtonian way, by subtracting kinetic energy. Finally, we rewrite the resulting nonlinear variational problem in terms of an unknown spinor field. We look for quasi-stationary solutions, i.e. solutions that harmonically oscillate in time. We prove that in the quasi-stationary setting our model is equivalent to a pair of massless Dirac equations. The crucial element of the proof is the observation that our Lagrangian admits a factorisation.

title: Как мы читаем гипертекст? (ответы феноменологической теории В. Изера)
Creators: name: Сергеева, О. В.
Publisher: name: Реноме
Year: 2023

description: Автор рассматривает идеи феноменологии чтения немецкого теоретика литературы В. Изера (1926-2007), с целью сравнения практики чтения традиционных линейных и новых нелинейных текстов, вошедших в обиход благодаря компьютерной технологии. Поколения, воспитанные в эпоху преобладания книжного чтения, часто опасаются «мозаичности» восприятия реальности цифровыми поколениями, которые оперируют преимущественно гипертекстами. Мозаичность и смысловые разрывы характеризуют не только гипертекст. Феноменология чтения обращает внимание на активность читателя по созданию связного впечатления от читаемого произведения. То есть любой текст, а не только компьютерный, предполагает точки переходов и пробелов в повествовании, что активизирует горизонт ожиданий читающего. Автор делает вывод, что принципиальное отличие практики чтения гипертекста от обычного – в неограниченности рамками начала и конца повествования и, следовательно, в сложности разделения текста и контекста.
On the Structure of the Effective Potential for a Spherical Wormhole

Year: 2009
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The structure of the effective potential $V$ describing causal geodesics near the throat of an arbitrary spherical wormhole is analyzed. Einstein's equations relative to a set of regular coordinates covering a vicinity of the throat imply that any spherical wormhole can be constructed from solutions of an effective initial value problem with the throat serving as an initial value surface. The initial data involve matter variables, the area A(0) of the throat and the gradient $Λ(0)$ of the red shift factor on the throat. Whenever $Λ(0)=0$, the effective potential $V$ has a critical point on the throat. Conditions upon the data are derived ensuring that the critical point is a local minimum (resp. maximum). For particular families of Quasi-Schwarzschild wormholes, $V$ exhibits a local minimum on the throat independently upon the energy $E$ and angular momentum $L^2 $ of the test particles and thus such wormholes admit stable circular timelike and null geodesics on the throat. For families of Chaplygin wormholes, we show that such geodesics are unstable. Based on a suitable power series representation of the metric, properties of $V$ away from the throat are obtained that are useful for the analysis of accretion disks and radiation processes near the throat of any spherical wormhole.

description: Let $X$ be a connected Riemannian manifold such that the resolvent of the free Laplacian $(Δ-z)^{-1}, z\in\C\setminus\R^{+},$ has a meromorphic continuation through $\R^{+}$. The poles of this continuation are called resonances. When $X$ has some symmetries, we construct complex-valued potentials, $V$, such that the resolvent of $Δ+V$, which has also a meromorphic continuation, has the same resonances with multiplicities as the free Laplacian.

description: We explore the use of remapping techniques to improve the efficiency of highly-multiplexed fibre systems for astronomical spectroscopy. This is particularly important for the implementation of Diverse Field Spectroscopy (DFS, described in Paper II) using highly-multiplexed monolithic fibre systems (MFS). Diverse Field Spectroscopy allows arbitrary distributions of target regions to be addressed to optimise observing efficiency when observing complex, clumpy structures such as protoclusters which will be increasingly accessible to Extremely Large Telescopes (ELTS). We show how the adoption of various types of remapping between the input and output of a Monolithic Fibre Systems can allow contiguous regions of spatial elements to be selected using only simple switch arrays. Finally we show how this compares in efficiency with integral-field and multiobject spectroscopy by simulations using artificial and real catalogues of objects. With the adoption of these mapping strategies, DFS outperforms other techniques when addressing a range of realistic target distributions. These techniques are also applicable to bio-medical science and were in fact inspired by it.

Kinetics of the Cu(II) catalysed reduction of Dichrmoate by hydrogen in aqueous solutions
Creators: name: Hahn, Edmund Alexander
Publisher: name: University of British Columbia
Year: 2011

description: The kinetics of the Cu⁺⁺ catalysed reduction of dichromate by hydrogen in aqueous perchlorate solutions were investigated between 160° and 200°C. A significant dependence of rates on Cr[superscript](VI) was observed. The mechanism proposed to account for the kinetics gave rise to a rate law of the form [formula omitted] where the rate constant for the hydrogen activation step, k₁, is given by [formula omitted]. The rate constant ratios k₋₁/k₂ and k₋₁/k₃ are believed to be temperature independent in the temperature range under consideration, and have approximate values of 0.38 and 0.02 respectively. As a consequence of these studies a similar mechanism was proposed for the Cu⁺⁺ catalysed hydrogen-oxygen recombination reaction investigated by McDuffie and co-workers. According to this mechanism an apparent discrepancy between the observations of Halpern et al and those of the former workers can be explained.

We find remarkable phenomena in a temperature range around a tenth of the Fermi-temperature, accessible with present experimental techniques: at zero chemical potential, besides a conventional s-wave superconducting phase, unconventional superconductivity with non-local bond pairing arises. In a temperature versus doping phase diagram, the unconventional superconducting phase exhibits a dome structure, reminiscent of the phase diagram for high-temperature superconductors and heavy fermions.

description: A number of substellar companions to evolved cool stars have now been reported. Cool giants are distinct from their progenitor Main Sequence (MS) low-mass stars in a number of ways. First, the mass loss rates of cool giant stars are orders of magnitude greater than for the late-type MS stars. Second, on the cool side of the Linsky-Haisch "dividing line", K and M giant stars are not X-ray sources, although they do show evidence for chromospheres. As a result, cool star winds are largely neutral for those spectral types, suggesting that planetary or brown dwarf magnetospheres will not be effective in standing off the stellar wind. In this case one expects the formation of a bow shock morphology at the companion, deep inside its magnetosphere. We explore radio emissions from substellar companions to giant stars with ionised winds or neutral winds.

description: Possible effects of magnetic fields in core collapse supernovae rely on an efficient amplification of the weak pre-collapse fields. It has been suggested that the magneto-rotational instability (MRI) leads to rapid field growth. Although MRI studies exist for accretion discs, the application of their results to core collapse supernovae is inhibited as the physics of supernova cores is substantially different from that of accretion discs. We address the problem of growth and saturation of the MRI by means of semi-global simulations, which combine elements of global and local simulations by taking the presence of global background gradients into account and using a local computational grid. We analyze the dispersion relation of the MRI to identify different regimes of the instability. This analysis is complemented by simulations, where we consider a local computational box rotating at sub-Keplerian velocity, and where we allow for a radial entropy gradient. We identify six regimes of the MRI depending on the ratio of the entropy and angular velocity gradient. Our numerical models confirm the instability criteria and growth rates for all relevant regimes. The MRI grows exponentially within milliseconds the flow and magnetic field geometries being dominated by channel flows. The MRI growth ceases once the channels are disrupted by resistive instabilities (due to finite numerical conductivity), and MHD turbulence sets in. From an analysis of the growth rates of the resistive instabilities, we deduce scaling laws for the termination amplitude of the MRI which agree well with our numerical models. We determine the dependence of the development of coherent flow structures in the saturated state on the aspect ratio of the simulation boxes. [abridged]

description: This work reports a study of the nonlinear Hall Effect (HE) in the semimetallic ferromagnet EuB6. A distinct switch in its Hall resistivity slope is observed in the paramagnetic phase, which occurs at a single critical magnetization over a wide temperature range. The observation is interpreted as the point of percolation for entities of a more conducting and magnetically ordered phase in a less ordered background. With an increasing applied magnetic field, the conducting regions either increase in number or expand beyond the percolation limit, hence increasing the global conductivity and effective carrier density. An empirical two-component model expression provides excellent scaling and a quantitative fit to the HE data and may be applicable to other correlated electron systems.

description: A strong departure from Landau-Fermi liquid (LFL) behavior have been recently revealed in observed anomalies in both the magnetic susceptibility $χ$ and the muon and $\rm ^{63}Cu$ nuclear spin-lattice relaxation rates $1/T_1$ of ${\rm {YbCu_{5-x}Au_x}}$ ($x=0.6$). We show that the above anomalies along with magnetic-field-induced reentrance of LFL properties are indeed determined by the scaling behavior of the quasiparticle effective mass. We obtain the scaling behavior theoretically utilizing our approach based on fermion condensation quantum phase transition (FCQPT) notion. Our theoretical analysis of experimental data on the base of FCQPT approach permits not only to explain above two experimental facts in a unified manner, but to clarify the physical reasons for a scaling behavior of the longitudinal magnetoresistance in $\rm YbRh_2Si_2$.

The Multiverse Hierarchy

Year: 2009
Subjects: subject: Popular Physics (physics.pop-ph)

description: I survey physics theories involving parallel universes, arguing that they form a natural four-level hierarchy of multiverses allowing progressively greater diversity. Level I: A generic prediction of inflation is an infinite ergodic universe, which contains Hubble volumes realizing all initial conditions -- including an identical copy of you about 10^(10^29)m away. Level II: In chaotic inflation, other thermalized regions may have different physical constants, dimensionality and particle content. Level III: In unitary quantum mechanics, other branches of the wavefunction add nothing qualitatively new, which is ironic given that this level has historically been the most controversial. Level IV: Other mathematical structures give different fundamental equations of physics. The key question is not whether parallel universes exist (Level I is the uncontroversial cosmological concordance model), but how many levels there are. I discuss how multiverse models can be falsified and argue that there is a severe "measure problem" that must be solved to make testable predictions at levels II-IV.

The activity of zinc oxide in multicomponent slags
Creators: name: Davenport, William George
Publisher: name: University of British Columbia
Year: 2011

description: The activity of zinc oxide in multicomponent slags has been investigated. Activities were determined experimentally Toy equilibrating iron saturated brasses with slags containing iron oxide. Required activities in the Zn-Cu-Fe system were obtained from experimental iron saturation data and available information on the Zn-Cu and Cu-Fe systems. Where measurement was not possible, thermodynamic analyses of slag systems were carried out. Rigid activity patterns in the ZnO-SiO₂, ZnO-FeO-SiO₂, ZnO-CaO-SiO₂ and ZnO-FeO-CaO-SiO₂ systems have been developed from experimental and analytical data. Agreement with the activity data of Bell, Turner and Peters on ZnO-FeO-CaO-SiO₂ and Okunev and Bovykin on ZnO-FeO-SiO₂ type slags indicates that the present measurement technique provides a good basis for industrial slag investigations.

description: Northern Ireland has long been a contested territory. The 1998 Belfast/Good Friday Agreement seemed to offer a resolution to the long-standing conflict. However, it has been reawakened by Brexit. Brexit presents a threat in Northern Ireland because it raises the divisive question of the United Kingdom’s sovereignty over the region and the issue of the border. However, despite Nationalists’—a political identity group associated with the political ideology of Irish reunification—initial opposition to Brexit, many in this group now view Brexit as a potential opportunity to achieve their political goal of Irish unity. The aim of the present research is to examine the combined influence of the Nationalist’s identity and perceived Brexit threat on people’s understanding of the proximity of this political goal. We specifically test whether Nationalists’ strength of group identification, and the threat of Brexit, is linked to how likely people believe a United Ireland has become. In two studies, we found evidence for the prediction that strong ingroup identification is related to the perception that a United Ireland is more likely. In the second study, path analysis showed that this relationship is conditional on perceived threat. For Nationalists with stronger ingroup identification, the threat of Brexit is greater. Combined, these factors are linked to an increased sense that a United Ireland is likely. In the discussion, we consider the implications of our findings for polarization in this postagreement society

description: The application of photonics to astronomy offers major advantages in the area of highly-multiplexed spectroscopy, especially when applied to extremely large telescopes. These include the suppression of the near-infrared night-sky spectrum [J. Bland-Hawthorn et al, Opt. Express 12, 5902 (2004), S. G. Leon-Saval et al, Opt. Lett. 30, 2545 (2005)] and the miniaturisation of spectrographs so that they may integrated into the light-path of individual spatial samples [J. Bland-Hawthorn et al, Proc SPIE 6269, 62690N (2006)]. Efficient collection of light from the telescope requires multimode optical fibres and three-dimensional photonic devices. We propose ultrafast laser inscription (ULI) [R. R. Thomson et al, Opt. Express 15, 11691 (2007)] as the best technology to fabricate 3D photonic devices for astrophotonic applications.

description: (abridged) We use the 1.4 GHz VIMOS-VLA Deep Survey and the optical VVDS and the CFHT-LS to compare the properties of radio loud galaxies with respect to the whole population of optical galaxies. The availability of multiband photometry and high quality photometric redshifts allows to derive rest frame colors and radio luminosity functions down to a limit of a B rest-frame magnitude of M=-20. Galaxy properties and luminosity functions (LFs) are estimated up to z~1 for radio loud and radio quiet early and late type galaxies. Radio loud late type galaxies are redder than radio quiet objects of the same class and this is an effect related to the presence of more dust in stronger star forming galaxies. Moreover, we estimate optical LFs, stellar masses and star formation rate distributions for radio sources and compare them with those derived for a well defined control sample, finding that the probability for a galaxy to be a radio emitter significantly increases at high values of these parameters. Radio loud early type galaxies show luminosity evolution of their bivariate radio-optical LF, due to an evolution in the radio-optical ratio. The lack of evolution of the mass function of radio loud early type galaxies means that no new AGN are formed at z<1. On the contrary, radio loud late type objects show a strong evolution, both in luminosity and in density, of the radio LF for z>0.7. This evolution is the direct effect of the strong optical evolution of this class and no significant change with redshift of the radio-optical ratio is required. With the knowledge of the radio-optical ratio and the optical and radio LFs for late type galaxies, we estimated the star formation history of the Universe up to z~1.5, using optical galaxies as tracers of the global radio emission.

The deformation of copper whiskers
Creators: name: Saimoto, Shigeo
Publisher: name: University of British Columbia
Year: 2011

description: The deformation of copper whiskers was studied by testing them at room and low temperatures in a specially built tensometer. The whiskers were grown by the standard method of hydrogen reduction of cupric chloride. X-ray studies of straight and kinked whiskers showed that crystallographic directions of the whisker axis other than <100>, <110>, and <111> are possible. In addition the formation of coherent twins is possible in copper whiskers grown by the above method. Tensile tests at various temperatures revealed a step effect, a hesitant flow and yield points in the flow region which were explained by proposing dislocation mechanisms. Tensile tests in dilute sulphuric acid showed that the oxide coating is not solely responsible for the strength of whiskers.
Comparison of Clinical and Radiological Outcome of Carotid Angioplasty and Stenting after Direct Navigation Versus Exchange Methods: A Randomized Clinical Trial
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo

description: Background

The purpose of this study was to compare the frequency of microembolic brain infarcts after direct navigation method versus exchange method in carotid artery stenting and vertebral artery origin angioplasty.

Methods and Material

This is a prospective study conducted at Shiraz University of Medical Sciences in southern Iran. Consecutive patients undergoing “carotid angioplasty and stenting” and “vertebral artery origin stenting” were randomly assigned into two groups with “direct navigation method” and “exchange method.” Subsequently, postprocedural magnetic resonance imaging (MRI) including diffusion weighted imaging and apparent diffusion coefficient were obtained within the first 24 hours after completion of the procedure.

Results

In total, 89 patients were recruited (67% male, mean age: 72 years). Cases comprised of 38 left internal carotid arteries (ICAs), 38 right ICAs, 6 left vertebral artery origin, and 7 right vertebral artery origin. Forty patients underwent exchange method, while 49 underwent direct navigation method. There was only one clinical stroke that occurred in “exchange method” group. Fifteen patients (37.5%) in exchange group and 23 patients (46.9%) in direct navigation group developed diffusion restricted lesions. In exchange group, 13 patients (32.5%) had at least one diffusion restricted lesion ipsilateral to the target vessel, and three patients (7.5%) had at least one diffusion restricted lesion contralateral to the target vessel. In direct navigation group, these measures were 19 (38.8%) and 9 (18.4%). However, no statistically significant intergroup differences were observed. The only significant difference was bilateral infarct percentile, which was more common in the direct navigation method (0.032)
