Essays in the economics of insurance markets
Creators: name: Blazenko, George William
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation investigates several aspects of the economics of insurance markets. First, conditions under which policies with deductible provisions, coinsurance provisions, or premium rebates are optimal are given. Results of previous papers on indemnity costs are considered as special cases. For both personal and commercial lines of insurance, further applications consider income taxes, interest income and acquisition costs. Second, the effect of individuals' characteristics on the trade-off between risk-sharing and incentives in a competitive insurance market affected by moral hazard is studied. An increase in the utility cost of effort decreases both prevention and coverage, while an increase in productivity of effort decreases loss frequencies and increases coverage. Decreases of utility in the loss state increase both prevention and coverage. Additional results establish the effect of wealth and risk aversion changes. Third, features of insurance markets that affect the use of reinsurance are examined. An active reinsurance market exists when the direct market is imperfectly competitive. The manager of an insurance firm with monopoly power takes reinsurance in preference to holding this on own account. Market power in the reinsurance market also restricts reinsurance. The manager of a monopsonistic insurer takes reinsurance when risk aversion is greater than that of clients; this is consistent with the interests of owners. The use of reinsurance is then decreasing with the ratio of policy-holder to manager risk aversion coefficients. Costs incurred by either insurers or reinsurers in the reinsurance market reduce the use of reinsurance, while costs incurred by insurers in the original transaction leave coverage provided by insurers themselves unchanged.

description: Triggering of long-lived nuclear isomeric states via coupling to the atomic shells in the process of nuclear excitation by electron capture (NEEC) is studied. NEEC occurring in highly-charged ions can excite the isomeric state to a triggering level that subsequently decays to the ground state. We present total cross sections for NEEC isomer triggering considering experimentally confirmed low-lying triggering levels and reaction rates based on realistic experimental parameters in ion storage rings. A comparison with other isomer triggering mechanisms shows that, among these, NEEC is the most efficient.

description: The frictional heating by ion-neutral drift is calculated and its effect on isobaric thermal instability is carried out. Ambipolar drift heating of one-dimensional self-gravitating magnetized molecular slab is used under the assumptions of quasi-magnetohydrostatic and local ionization equilibrium. We see that ambipolar drift heating is inversely proportional to density and its value in some regions of the slab can be significantly larger than the average heating rates of cosmic rays and turbulent motions. The results show that the isobaric thermal instability can occur in some regions of the slab; therefore it may produce the slab fragmentation and formation of the AU-scale condensations.

description: Multi-task learning is increasingly used to investigate the association structure between multiple responses and a single set of predictor variables in many applications. In the era of big data, the coexistence of incomplete outcomes, large number of responses, and high dimensionality in predictors poses unprecedented challenges in estimation, prediction, and computation. In this paper, we propose a scalable and computationally efficient procedure, called PEER, for large-scale multi-response regression with incomplete outcomes, where both the numbers of responses and predictors can be high-dimensional. Motivated by sparse factor regression, we convert the multi-response regression into a set of univariate-response regressions, which can be efficiently implemented in parallel. Under some mild regularity conditions, we show that PEER enjoys nice sampling properties including consistency in estimation, prediction, and variable selection. Extensive simulation studies show that our proposal compares favorably with several existing methods in estimation accuracy, variable selection, and computation efficiency.

description: We propose a scheme to realize the fractional quantum Hall system with atoms confined in a two-dimensional array of coupled cavities. Our scheme is based on simple optical manipulation of atomic internal states and inter-cavity hopping of virtually excited photons. It is shown that as well as the fractional quantum Hall system, any system of hard-core bosons on a lattice in the presence of an arbitrary Abelian vector potential can be simulated solely by controlling the phases of constantly applied lasers. The scheme, for the first time, exploits the core advantage of coupled cavity simulations, namely the individual addressability of the components and also brings the gauge potential into such simulations as well as the simple optical creation of particles.

Accurate seeing measurements with MASS and DIMM

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

description: Astronomical seeing is quantified by a single parameter, turbulence integral, in the framework of the Kolmogorov turbulence model. This parameter can be routinely measured by a Differential Image Motion Monitor, DIMM. A new instrument, Multi-Aperture Scintillation Sensor (MASS), permits to measure the seeing in the free atmosphere above ~0.5km and, together with a DIMM, to estimate the ground-layer seeing. The absolute accuracy of both methods is studied here using analytical theory, numerical simulation, and experiments. A modification of the MASS data processing to compensate for partially saturated scintillation is developed. We find that the DIMM can be severely biased by optical aberrations (e.g. defocus) and propagation. Seeing measurements with DIMM and MASS can reach absolute accuracy of ~10% when their biases are carefully controlled. Pushing this limit to 1% appears unrealistic because the seeing itself is just a model-dependent parameter of a non-stationary random process.

Hard Electron Energy Distribution in the Relativistic Shocks of GRB Afterglows

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: Particle acceleration in relativistic shocks is not a very well understood subject. Owing to that difficulty, radiation spectra from relativistic shocks, such as those in GRB afterglows, have been often modelled by making assumptions about the underlying electron distribution. One such assumption is a relatively soft distribution of the particle energy, which need not be true always, as is obvious from observations of several GRB afterglows. In this paper, we describe modifications to the afterglow standard model to accommodate energy spectra which are `hard'. We calculate the overall evolution of the synchrotron and compton flux arising from such a distribution. We also model two afterglows, GRB010222 and GRB020813, under this assumption and estimate the physical parameters.

description: Here we reconstruct the Proportional Solution for Economies with both public and private ownership of productive assets, proving the existence of a competitive equilibrium assuming non-monotonic utility and actors behaving with envy. With a possibility for excess at no additional cost, our aim is to provide a mechanism under which envious individuals, competing for a commonly pooled resource, can reach a stable equilibrium. In other words, we derive a proportional solution with envious agents in a pure exchange economy.

description: INTPIX4NA is an integration-type silicon-on-insulator pixel detector. This detector has a 14.1 x 8.7 mm^2 sensitive area, 425,984 (832 column x 512 row matrix) pixels and the pixel size is 17 x 17 um^2. This detector was developed for residual stress measurement using X-rays (the cos alpha method). The performance of INTPIX4NA was tested with the synchrotron beamlines of the Photon Factory (KEK), and the following results were obtained. The modulation transfer function, the index of the spatial resolution, was more than 50% at the Nyquist frequency (29.4 cycle/mm). The energy resolution analyzed from the collected charge counts is 35.3%--46.2% at 5.415 keV, 21.7%--35.6% at 8 keV, and 15.7%--19.4% at 12 keV. The X-ray signal can be separated from the noise even at a low energy of 5.415 keV at room temperature (approximately 25--27 degree Celsius). The maximum frame rate at which the signal quality can be maintained is 153 fps in the current measurement system. These results satisfy the required performance in the air and at room temperature (approximately 25--27 degree Celsius) condition that is assumed for the environment of the residual stress measurement.

description: We propose a principle of consistency between different hierarchical levels of biological systems. Given a consistency between molecule replication and cell reproduction, universal statistical laws on cellular chemical abundances are derived and confirmed experimentally. They include a power law distribution of gene expressions, a lognormal distribution of cellular chemical abundances over cells, and embedding of the power law into the network connectivity distribution. Second, given a consistency between genotype and phenotype, a general relationship between phenotype fluctuations by genetic variation and isogenic phenotypic fluctuation by developmental noise is derived. Third, we discuss the chaos mechanism for stem cell differentiation with autonomous regulation, resulting from a consistency between cell reproduction and growth of the cell ensemble.

Symmetric and asymmetric solitons in linearly coupled Bose-Einstein condensates trapped in optical lattices

Year: 2007
Subjects: subject: Pattern Formation and Solitons (nlin.PS)
subject: FOS: Physical sciences

description: We study spontaneous symmetry breaking in a system of two parallel quasi-one-dimensional traps, equipped with optical lattices (OLs) and filled with a Bose-Einstein condensate (BEC). The cores are linearly coupled by tunneling. Analysis of the corresponding system of linearly coupled Gross-Pitaevskii equations (GPEs) reveals that spectral bandgaps of the single GPE split into subgaps. Symmetry breaking in two-component BEC solitons is studied in cases of the attractive (AA) and repulsive (RR) nonlinearity in both traps; the mixed situation, with repulsion in one trap and attraction in the other (RA), is considered too. In all the cases, stable asymmetric solitons are found, bifurcating from symmetric or antisymmetric ones (and destabilizing them), in the AA and RR systems, respectively. In either case, bi-stability is predicted, with a nonbifurcating stable branch, either antisymmetric or symmetric, coexisting with asymmetric ones. Solitons destabilized by the bifurcation tend to rearrange themselves into their stable asymmetric counterparts. The impact of a phase mismatch, between the OLs in the two cores is also studied. Also considered is a related model, for a binary BEC in a single-core trap with the OL, assuming that the two species (representing different spin states of the same atom) are coupled by linear interconversion. In that case, the symmetry-breaking bifurcations in the AA and RR models switch their character, if the inter-species nonlinear interaction becomes stronger than the intra-species nonlinearity.

description: Preliminary results on KUV 02464+3239, a pulsating DA white dwarf are presented. Located near the red edge of the DAV instability strip, KUV 02464+3239 shows large amplitude and long period pulsation modes. Up to now only one mode was known from a 50-minute-long light curve. Our more extended observations allowed the identification of three additional frequencies. The presence of previously known harmonics were confirmed and weak subharmonics are also noticeable at some parts of the light curve. This suggests the dominance of nonlinear pulsation effects from time to time.

description: Ultraviolet light curves constructed from NUV and FUV detectors on GALEX reveal large amplitude variations during the orbital period of the Low Accretion Rate Polar MQ Dra (SDSSJ1553+55). This unexpected variation from a UV source is similar to that seen and discussed in the Polar EF Eri during its low state of accretion, even though the accretion rate in MQ Dra is an order of magnitude lower than even the low state of EF Eri. The similarity in phasing of the UV and optical light curves in MQ Dra imply a similar location for the source of light. We explore the possibilities of hot spots and cyclotron emission with simple models fit to the UV, optical and IR light curves of MQ Dra. To match the GALEX light curves with a single temperature circular hot spot requires different sizes of spots for the NUV and FUV, while a cyclotron model that can produce the optical harmonics with a magnetic field near 60 MG requires multipoles with fields > 200 MG to match the UV fluxes.

We use these results to show that the relevant entanglement measures satisfy the generalized Coffman-Kundu-Wootters formula of distributed entanglement. An explicit formula for the residual tangle is also given. The geometry of such density matrices is elaborated in some detail. In particular an explicit form for the Bures metric is given.

Analysis of hematopoiesis in human normal long-term marrow cultures and in cultures from patients with CML and AML
Creators: name: Coulombel, Laure
Publisher: name: University of British Columbia
Year: 2010

description: The hematopoietic system supplies short-lived functional end cells of multiple lineages from a common pool of pluripotent stem cells throughout life. In man neoplastic transformation of these stem cells results in the development of the acute and chronic myeloid leukemias. An in vitro system where functional murine stem cells can be maintained for several months has recently become available. This system has been a powerful tool to analyze mechanisms regulating normal hematopoiesis and leukemogenesis in mice. The purpose of this work was to develop an analogous culture system applicable to human marrow and to evaluate its ability to support leukemic hematopoiesis. Long-term cultures were established with normal human marrow cells. In these, the more primitive progenitors were found to be almost exclusively located in the adherent layer for the duration of the culture (i.e., at least 2 months). A prerequisite for these studies was the development of a procedure for detaching adherent cells so that various colony-forming progenitors could be assayed in semi-solid media. The consistent finding of adherent layer-associated hematopoiesis suggests that cell-cell interactions between primitive hematopoietic cells and adherent layer elements may be essential for the maintenance of the former. Long-term cultures were also initiated with marrow from 11 CML patients and 13 AML patients (all untreated) and maintenance of normal and neoplastic progenitor cell populations assessed. A common finding was the rapid disappearance of neoplastic progenitor cells (recognized either by the presence of chromosomal abnormalities or by their abnormal differentiation capacity) in most cultures, even though cytogenetically normal precursors were often maintained. These differences between the behaviour of normal and neoplastic cells in long-term cultures may reflect changes at the stem cell level that are related to the acquisition of abnormal growth properties. In a minority of patients a different result was obtained. Clonal dominance persisted in vitro and normal hematopoiesis was not detected. Thus long-term cultures have also allowed differences in the behaviour of primitive neoplastic cells from different patients to be revealed. Future investigation of the basis for these differences may provide new insights into the biological heterogeneity that characterizes these disorders

description: This paper introduces a version of empirical likelihood based on the periodogram and spectral estimating equations. This formulation handles dependent data through a data transformation (i.e., a Fourier transform) and is developed in terms of the spectral distribution rather than a time domain probability distribution. The asymptotic properties of frequency domain empirical likelihood are studied for linear time processes exhibiting both short- and long-range dependence. The method results in likelihood ratios which can be used to build nonparametric, asymptotically correct confidence regions for a class of normalized (or ratio) spectral parameters, including autocorrelations. Maximum empirical likelihood estimators are possible, as well as tests of spectral moment conditions. The methodology can be applied to several inference problems such as Whittle estimation and goodness-of-fit testing.

description: In a recent Letter (Phys. Rev. Lett. \textbf{98}, 083601 (2007), arXiv:cond-mat/0610804), O. Assaf and E. Akkermans claim that the angular correlations of the light intensity scattered by a cloud of cold atoms with internal degeneracy (Zeeman sublevels) of the ground state overcome the usual Rayleigh law. More precisely, they found that they become exponentially large with the size of the sample. In what follows, we will explain why their results are wrong and, in contrary, why the internal degeneracy leads to lower intensity correlations.

description: One of the most challenging issues in the characterization of magnetic materials is to obtain quantitative analysis on the nanometer scale. Here we describe how electron magnetic circular dichroism (EMCD) measurements using the transmission electron microscope (TEM) can be used for that purpose, utilizing reciprocal space maps. Applying the EMCD sum rules, an orbital to spin moment ratio of $m_L/m_S=0.08 \pm 0.01$ is obtained for Fe, which is consistent with the commonly accepted value. Hence, we establish EMCD as a quantitative element specific technique for magnetic studies, using a widely available instrument with superior spatial resolution.

description: In this paper, we investigate the thermal stability and Joule-Thomson expansion of some new qusitopological black hole solutions. We first study the higher-dimensional static quasitopological black hole solutions in the presence of Born-Infeld, exponential and logarithmic nonlinear electrodynamics. The stable regions of these solutions are independent of the types of the nonlinear electrodynamics. The solutions with the horizons relating to the positive constant curvature, $k=+1$, have a larger region in thermal stability, if we choose positive quasitopological coefficients, $μ_{i}>0$. We also have a review on the power Maxwell quasitopological black hole. Then, we obtain the five-dimensional Yang-Mills quasitopological black hole solution and compare with the quasitopological Maxwell solution. For large values of the electric charge, $q$, and the Yang-Mills charge, $e$, we showed that the stable range of the Maxwell quasitopological black hole is larger than the Yang-Mills one. This is while thermal stability for small charges has the same behavior for these black holes. In the following, we obtain the thermodynamic quantities for these solutions and then study the Joule-Thomson expansion. We consider the temperature changes in an isenthalpy process during this expansion. The obtained results show that the inversion curves can divide the isenthalpic ones into two parts in the inversion pressure, $P_{i}$. For $PP_{i}$. As the values of the nonlinear parameter, $β$, the electric and Yang-Mills charges decrease, the temperature goes to zero with a small slope and so the heating phenomena happens slowly.

Unlike Euxoa macleani, which occurs only as a single form (Figs 10–12) with a dark brownish-gray forewing with most maculation obscure except for black transverse lines and medial line, E. chimoensis occurs in three color forms with two pattern forms. The forewing may be reddish brown, blackish brown or gray. For each of these color forms the forewing occurs in two pattern forms; in one form (Figs 13, 14) the transverse lines are prominent and the reniform and orbicular spots are similar to the ground color or darker; in the second form (Figs 15–18) the transverse lines and or- bicular and reniform spots appear mainly paler than the ground color; both of these forms seem to be equally common in Quebec and Labrador, but only the form with pale markings is known from the west coast of Hudson Bay. Forewing length varies from 13 to 17 mm. The male and female genitalia (Figs 23, 28) are similar to those of E. macleani (Figs 22, 27), but the appendix bursae in E. chimoensis projects mainly to the left, whereas in that of E. macleani has a lobe of the appendix bursae that projects posteriorly giving the appendix a longitudinal orientation. Distribution and biology. Euxoa chimoensis is known only from two localities in Labrador, three in Quebec, and one in Manitoba, but these are widely scattered and indicate that the species is widely distributed in Labrador and northern Quebec and along the west coast of Hudson Bay. Adults have been collected throughout July. Acknowledgments We thank Jocelyn Gill (CNC, Ottawa) for assistance with the preparation of the genitalia and photographs.

description: We report the relative abundances of 17 elements in the atmosphere of the white dwarf star GD 362, material that, very probably, was contained previously in a large asteroid or asteroids with composition similar to the Earth/Moon system. The asteroid may have once been part of a larger parent body not unlike one of the terrestrial planets of our solar system.

description: An ultrafast spin current can be induced by femtosecond laser excitation in a ferromagnetic (FM) thin film in contact with a nonmagnetic (NM) metal. The propagation of an ultrafast spin current into NM metal has recently been found in experiments to generate transient spin accumulation. Unlike spin accumulation in equilibrium NM metals that occurs due to spin transport at the Fermi energy, transient spin accumulation involves highly nonequilibrium hot electrons well above the Fermi level. To date, the diffusion and dissipation of this transient spin accumulation has not been well studied. Using the superdiffusive spin transport model, we demonstrate how spin accumulation is generated in NM metals after laser excitation in an FM|NM bilayer. The spin accumulation shows an exponential decay from the FM|NM interface, with the decay length increasing to the maximum value and then decreasing until saturation. By analyzing the ultrafast dynamics of laser-excited hot electrons, the "effective mean free path", which can be characterized by the averaged product of the group velocity and lifetime of hot electrons, is found to play a key role. The interface reflectivity has little influence on the spin accumulation in NM metals. Our calculated results are in qualitative agreement with recent experiments.

description: Monte Carlo cluster algorithms are popular for their efficiency in studying the Ising model near its critical temperature. We might expect that this efficiency extends to the bond-diluted Ising model. We show, however, that this is not always the case by comparing how the correlation times $τ_w$ and $τ_{\rm sw}$ of the Wolff and Swendsen-Wang cluster algorithms scale as a function of the system size $L$ when applied to the two-dimensional bond-diluted Ising model. We demonstrate that the Wolff algorithm suffers from a much longer correlation time than in the pure Ising model, caused by isolated (groups of) spins which are infrequently visited by the algorithm. With a simple argument we prove that these cause the correlation time $τ_w$ to be bounded from below by $L^{z_w}$ with a dynamical exponent $z_w=γ/ ν\approx 1.75$ for a bond concentration $p < 1$. Furthermore, we numerically show that this lower bound is actually taken for several values of $p$ in the range $0.5 < p < 1$. Moreover, we show that the Swendsen-Wang algorithm does not suffer from the same problem. Consequently, it has a much shorter correlation time, shorter than in the pure Ising model even. Numerically at $p = 0.6$, we find that its dynamical exponent is $z_{\rm sw} = 0.09(4)$.

description: Wholesale electricity markets have been of academic interest, particularly in response to privatisation of electricity markets around the world. The overarching theme of the thesis is that any improvements to the efficiency of pricing in electricity markets can have potential benefits to the population at large. This thesis examines some economic quantities in the German wholesale electricity market and the econometric techniques involved in their analysis. The methods employed in this thesis are relatively simple, but all show improvements over existing approaches. These findings suggest that improved understanding of electricity markets need not be associated with high levels of complexity.
Is there Evidence for a Hubble bubble? The Nature of Type Ia Supernova Colors and Dust in External Galaxies

description: We examine recent evidence from the luminosity-redshift relation of Type Ia Supernovae (SNe Ia) for the $\sim 3 σ$ detection of a ``Hubble bubble'' -- a departure of the local value of the Hubble constant from its globally averaged value \citep{Jha:07}. By comparing the MLCS2k2 fits used in that study to the results from other light-curve fitters applied to the same data, we demonstrate that this is related to the interpretation of SN color excesses (after correction for a light-curve shape-color relation) and the presence of a color gradient across the local sample. If the slope of the linear relation ($β$) between SN color excess and luminosity is fit empirically, then the bubble disappears. If, on the other hand, the color excess arises purely from Milky Way-like dust, then SN data clearly favors a Hubble bubble. We demonstrate that SN data give $β\simeq 2$, instead of the $β\simeq 4$ one would expect from purely Milky-Way-like dust. This suggests that either SN intrinsic colors are more complicated than can be described with a single light-curve shape parameter, or that dust around SN is unusual. Disentangling these possibilities is both a challenge and an opportunity for large-survey SN Ia cosmology.

The quest to quantify selective and synergistic effects of plasma for cancer treatment: Insights from mathematical modeling

description: Cold atmospheric plasma (CAP) and plasma-treated liquids (PTLs) have recently become a promising option for cancer treatment, but the underlying mechanisms of the anti-cancer effect are still to a large extent unknown. Although hydrogen peroxide has been recognized as the major anti-cancer agent of PTL and may enable selectivity in a certain concentration regime, the co-existence of nitrite can create a synergistic effect. We develop a mathematical model to describe the key species and features of the cellular response towards PTL. From the numerical solutions, we define a number of dependent variables, which represent feasible measures to quantify cell susceptibility in terms of the hydrogen peroxide membrane diffusion rate constant and the intracellular catalase concentration. For each of these dependent variables, we investigate the regimes of selective versus non-selective, and of synergistic versus non-synergistic effect to evaluate their potential role as a measure of cell susceptibility. Our results suggest that the maximal intracellular hydrogen peroxide concentration, which in the selective regime is almost four times greater for the most susceptible cells compared to the most resistant cells, could be used to quantify the cell susceptibility towards exogenous hydrogen peroxide. We believe our theoretical approach brings novelty to the field of plasma oncology, and more broadly, to the field of redox biology, by proposing new ways to quantify the selective and synergistic anti-cancer effect of PTL in terms of inherent cell features.

Diagnosis. This widespread species can be distinguished from other taxa from tropical Asia and Australasia by having a pink dorsal side of the abdomen in both the male and the female. Externally, it resembles A. eugenia (Fabricius, 1794) (type locality India) but can be distinguished from it by having a grey ground color of the wings, a lesser curved ampulla, and larger coremata. This species can be separated from A. rhodopa Walker, 1864 (type locality India) and A. vitrea Plötz, 1880 (type locality West Africa) by having a clear dark, elongated spot between the cell apex and the costa on the forewing, and from A. fumida (Swinhoe, 1901) (type locality Indonesia: Halmaheira Is.; Timor) by having semitransparent wings.
Distribution. India, Sri-Lanka, Nepal, mainland China, Taiwan, the Philippines, Indochina, Indonesia, and New Guinea (Dubatolov 2010). On the Flores Island, this species was recorded from the sea level to 1100 m a.s.l. (Bolotov et al. 2018; this study).

description: In the framework of the mimetic approach, we study the $f(R,R_{μν}R^{μν})$ gravity with the Lagrange multiplier constraint and the scalar potential. We introduce field equations for the discussed theory and overview their properties. By using the general reconstruction scheme we obtain the power law cosmology model for the $f(R,R_{μν}R^{μν})=R+d(R_{μν}R^{μν})^p$ case as well as the model that describes symmetric bounce. Moreover, we reconstruct model, unifying both matter dominated and accelerated phases, where ordinary matter is neglected. Using inverted reconstruction scheme we recover specific $f(R,R_{μν}R^{μν})$ function which give rise to the de-Sitter evolution. Finally, by employing the perfect fluid approach, we demonstrate that this model can realize inflation consistent with the bounds coming from the BICEP2/Keck array and the Planck data. Thus, it is suggested that the introduced extension of the mimetic regime may describe any given cosmological model.
