Information systems analysis for the computerization of a long range financial planning model : a case study
Creators: name: Argyle, Janice Elaine
Publisher: name: University of British Columbia
Year: 2011

description: Information systems analysis was done for the computerization of an existing long range financial planning model, in case study form. The model, that of Lockheed Petroleum Services Limited, was analyzed and recommendations for model sophistication were made. Computerization was justified by projected cost reduction and several other advantages which were judged to outweigh the disadvantages of computerization. Implications of computerization and difficulties of information systems analysis were described. Results of the study were the design of a detailed algorithm and of ancillary documents making future computer programming, verification, and implementation easily achievable.

description: We discuss mm-wavelength radio, 2.2-11.8um NIR and 2-10 keV X-ray light curves of the super massive black hole (SMBH) counterpart of Sagittarius A* (SgrA*) near its lowest and highest observed luminosity states. The luminosity during the low state can be interpreted as synchrotron emission from a continuous or even spotted accretion disk. For the high luminosity state SSC emission from THz peaked source components can fully account for the flux density variations observed in the NIR and X-ray domain. We conclude that at near-infrared wavelengths the SSC mechanism is responsible for all emission from the lowest to the brightest flare from SgrA*. For the bright flare event of 4 April 2007 that was covered from the radio to the X-ray domain, the SSC model combined with adiabatic expansion can explain the related peak luminosities and different widths of the flare profiles obtained in the NIR and X-ray regime as well as the non detection in the radio domain.

description: We present a new method to remove the impact of random and small-scale non-circular motions from HI velocity fields in galaxies in order to better constrain the dark matter properties for these objects. This method extracts the circularly rotating velocity components from the HI data cube and condenses them into a so-called bulk velocity field. We derive high-resolution rotation curves of IC 2574 and NGC 2366 based on bulk velocity fields derived from The HI Nearby Galaxy Survey (THINGS) obtained at the VLA. The bulk velocity field rotation curves are significantly less affected by non-circular motions and constrain the dark matter distribution in our galaxies, allowing us to address the discrepancy between the inferred and predicted dark matter distribution in galaxies (the "cusp/core" problem). Spitzer Infrared Nearby Galaxies Survey (SINGS) 3.6 micron data as well as ancillary optical information, are used to separate the baryons from the total matter content. Using stellar population synthesis models, assuming various sets of metallicity and star formation histories, we compute stellar mass-to-light ratios for the 3.6 and 4.5 micron bands. Using our predicted value for the 3.6 micron stellar mass-to-light ratio, we find that the observed dark matter distributions of IC 2574 and NGC 2366 are inconsistent with the cuspy dark matter halo predicted by LCDM models, even after corrections for non-circular motions. This result also holds for other assumptions about the stellar mass-to-light ratio. The distribution of dark matter within our sample galaxies is best described by models with a kpc-sized constant-density core.

An analysis of infrared emission spectra from the regions near the Galactic Center
Creators: name: Contini, M.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: We present consistent modelling of line and continuum IR spectra in the region close to the Galactic center. The models account for the coupled effect of shocks and photoionization from an external source. The results show that the shock velocities range between 65 and 80 km/s, the pre-shock densities between 1 cm-3 in the ISM to 200 cm-3 in the filamentary structures. The pre-shock magnetic field increases from 5. 10^{-6} gauss in the surrounding ISM to ~8. 10^{-5} gauss in the Arched Filaments. The stellar temperatures are ~38000 K in the Quintuplet cluster and ~27000 K in the Arches Cluster. The ionization parameter is relatively low (<0.01) with the highest values near the clusters, reaching a maximum >0.01 near the Arches Cluster. Depletion from the gaseous phase of Si is found throughout the whole observed region, indicating the presence of silicate dust. Grains including iron, are concentrated throughout the Arched Filaments. The modelling of the continuum SED in the IR range, indicates that a component of dust at temperatures of ~100-200 K is present in the central region of the Galaxy. Radio emission appears to be thermal bremsstrahlung in the E2-W1 filaments crossing strip, however a synchrotron component is not excluded. More data are necessary to resolve this questions.

description: The new quaternary iron arsenide-fluoride SrFeAsF with the tetragonal ZrCuSiAs-type structure was synthesized and the crystal structure was determined by X-ray powder diffraction (P4/nmm, a = 399.30(1), c = 895.46(1) pm). SrFeAsF undergoes a structural and magnetic phase transition at 175 K, accompanied by strong anomalies in the specific heat, electrical resistance and magnetic susceptibility. In the course of this transition, the space group symmetry changes from tetragonal (P4/nmm) to orthorhombic (Cmme). 57Fe Moessbauer spectroscopy experiments show a single signal at room temperature at an isomer shift of 0.30(1) mm/s and magnetic hyperfine-field splitting below the phase transition temperature. Our results clearly show that SrFeAsF exhibits a spin density wave (SDW) anomaly at 175 K very similar to LaFeAsO, the parent compound of the iron arsenide-oxide superconductors and thus SrFeAsF may serve as a further parent compound for oxygen-free iron arsenide superconductors.

description: The problem of spectra formation in hydrodynamic approach to A+A collisions is considered within the Boltzmann equations. It is shown analytically and illustrated by numerical calculations that the particle momentum spectra can be presented in the Cooper-Frye form despite freeze-out is not sharp and has the finite temporal width. The latter is equal to the inverse of the particle collision rate at points $(t_σ({\bf r},p),{\bf r})$ of the maximal emission at a fixed momentum $p$. The set of these points forms the hypersurfaces $t_σ({\bf r},p)$ which strongly depend on the values of $p$ and typically do not enclose completely the initially dense matter. This is an important difference from the standard Cooper-Frye prescription (CFp), with a common freeze-out hypersurface for all $p$, that affects significantly the predicted spectra. Also, the well known problem of CFp as for negative contributions to the spectra from non-space-like parts of the freeze-out hypersurface is naturally eliminated in this improved prescription.

Centrioles are frequently amplified in early B cell development but dispensable for humoral immunity

centrosome amplification

description: Centrioles define centrosome structure and function. Deregulation of centriole numbers can cause developmental defects and foster malignant disease. The p53 tumor suppressor limits the growth of cells lacking or harboring additional centrioles and can be engaged by the “mitotic surveillance” or the “PIDDosome pathway”, respectively. Here, we show that early B cell progenitors frequently present extra centrioles that are rapidly lost during maturation. Increasing centriole counts beyond physiological levels by Polo-like kinase 4 (PLK4) overexpression induces apoptosis, suggesting clearance of such cells during development. Remarkably, this apoptotic response is independent of PIDD1 or p53, but can be blocked by excess BCL2. In contrast, loss of centrosomes upon Plk4 deletion arrests B cell development at the pro B cell stage. This defect can be rescued by co-deletion of Usp28, a critical component of the mitotic surveillance pathway that restores cell number and function in the absence of centrioles. In both scenarios, too many and too few centrosomes, mitochondrial apoptosis is engaged to kill B cells with abnormal centriole counts during their development with progenitor B cells being intolerant to centriole loss but permissive to centriole amplification. Unexpectedly, our findings show that centrioles are dispensable for mounting an effective humoral immune response.

description: We describe an application of the MultiNest algorithm to gravitational wave data analysis. MultiNest is a multimodal nested sampling algorithm designed to efficiently evaluate the Bayesian evidence and return posterior probability densities for likelihood surfaces containing multiple secondary modes. The algorithm employs a set of live points which are updated by partitioning the set into multiple overlapping ellipsoids and sampling uniformly from within them. This set of live points climbs up the likelihood surface through nested iso-likelihood contours and the evidence and posterior distributions can be recovered from the point set evolution. The algorithm is model-independent in the sense that the specific problem being tackled enters only through the likelihood computation, and does not change how the live point set is updated. In this paper, we consider the use of the algorithm for gravitational wave data analysis by searching a simulated LISA data set containing two non-spinning supermassive black hole binary signals. The algorithm is able to rapidly identify all the modes of the solution and recover the true parameters of the sources to high precision.

Symmetries of the relativistic two-boson system in external field

description: We investigate the survival of symmetries in a relativistic system of two mutually interacting bosons coupled with an external field, when this field is "strongly" translation invariant in some directions and additionally remains unchanged by other isometries of spacetime. Since the relativistic interactions cannot be composed additively, it is not a priori garanteed that the two-body system inherits all the symmetries of the external potential. However, using an ansatz which permits to preserve the compatibility of the mass-shell constraints in the presence of the field, we show how "surviving isometries" can actually be implemented in the two-body wave equations.

The export development corporation : its role and effectiveness in British Columbia
Creators: name: Brown, James Gervin
Publisher: name: University of British Columbia
Year: 2011

description: The objective of this thesis is the evaluation of the Export Development Corporation's effectiveness in British Columbia. This objective is readily devisable into two tasks, an examination of the Corporation's programs in terms of its objectives, and the assessment of the performance and potential of the programs in British Columbia. In Chapter I, a theory of the role of export credit in trade expansion is developed. The importer's demand for export credit and the exporter's supply of that credit are examined separately, and the joint effect of both on trade volume is considered. The effect of export credit insurance and financing in altering trade volume is also presented. The questionnaire, sample, and method of analysis are described. In Chapter II, a profile is presented of British Columbia exporters answering the questionnaire. Six characteristics are examined: industry sector, export experience, sales volume, number of export markets, relative importance of exports and domestic sales, and the relative profitability of exports and domestic sales as perceived by the respondent. In Chapter III, risk perception and compensation are considered. Sample data are presented regarding the relative risk of exports and domestic business, the explanation of that risk, and the difference in selling terms which is deemed in part to compensate for risk differentials. A theory of the effect of risk on profitability is presented and a joint relationship of credit terms, profitability, and risk developed. The theory and data of the first three chapters suggest that the Corporation's services should greatly enhance the export profitability of B.C. firms. However, the response to these services has not been as positive as is to be expected. Chapter IV presents respondent attitudes toward EDC programs. Information sources are suggested as a possible explanation for negative attitudes, and evidence is presented to suggest that the confidence of firms in sources from which they learn of EDC is suspect. Three appendices are included to provide background for the study; the questionnaire, export credit services in other major trading countries, and a description of the historical performance and present status of the Export Development Corporation. This study concludes that the programs of the Corporation are rational in view of its objectives, and that the potential for export expansion in British Columbia is considerable. However, acceptance to date has been poor as a result of an information gap which can be overcome to a great extent by efforts of the Corporation.

PsOF is grouped under benign fibro-osseous lesion as a separate entity. The lesion is seen in all age groups and is not restricted to younger age only. It is highly aggressive and needs to be differentiated from other benign fibro-osseous lesions that are not aggressive. The lesion typically affects paranasal sinuses commonly and shows presence of ossicles known as a psammoma bodies. The classification of this lesion has seen a dramatic change over a period of 2 decades. We hereby report a case of Psammomatoid ossifying fibroma of mandible with review of literature.

description: The observed D0 - anti-D0 oscillations provide a new stage in our search for New Physics in heavy flavour dynamics. The theoretical verdict on the observed values of x_D and y_D remains ambiguous: while they could be totally generated by Standard Model dynamics, they could also contain a sizable or even leading contribution from New Physics. Those oscillations are likely to enhance the observability of CP violation as clear manifestations of New Physics. We present general formulae for D0 - anti-D0 oscillations, concentrating on the case of negligible direct CP violation. In particular we derive a general formula for the time-dependent mixing-induced CP asymmetry in decays to a CP eigenstate and its correlation with the semileptonic CP asymmetry a_SL(D0) in D0(t) -> l nu K. We apply our formalism to the Littlest Higgs model with T-parity, using the time-dependent CP asymmetry in D -> K_S phi as an example. We find observable effects at a level well beyond anything possible with CKM dynamics. Comparisons with CP violation in the K and B systems offer an excellent test of this scenario and reveal the specific pattern of flavour and CP violation in the D0 - anti-D0 system predicted by this model. We discuss a number of charm decays that could potentially offer an insight in the dynamics of CP violation in D decays. We also apply our formalism to B_s - anti-B_s mixing.

Domain walls of ferroelectric BaTiO3 within the Ginzburg-Landau-Devonshire phenomenological model

description: Mechanically compatible and electrically neutral domain walls in tetragonal, orthorhombic and rhombohedral ferroelectric phases of BaTiO3 are systematically investigated in the framework of the phenomenological Ginzburg-Landau-Devonshire (GLD) model with parameters of Ref. [Hlinka and Marton, Phys. Rev. 74, 104104 (2006)]. Polarization and strain profiles within domain walls are calculated numerically and within an approximation leading to the quasi-one-dimensional analytic solutions applied previously to the ferroelectric walls of the tetragonal phase [W. Cao and L.E. Cross, Phys. Rev. 44, 5 (1991)]. Domain wall thicknesses and energy densities are estimated for all mechanically compatible and electrically neutral domain wall species in the entire temperature range of ferroelectric phases. The model suggests that the lowest energy walls in the orthorhombic phase of BaTiO3 are the 90-degree and 60-degree walls. In the rhombohedral phase, the lowest energy walls are the 71-degree and 109-degree walls. All these ferroelastic walls have thickness below 1 nm except for the 90-degree wall in the tetragonal phase and the 60-degree S-wall in the orthorhombic phase, for which the larger thickness of the order of 5 nm was found. The antiparallel walls of the rhombohedral phase have largest energy and thus they are unlikely to occur. The calculation indicates that the lowest energy structure of the 109-degree wall and few other domain walls in the orthorhombic and rhombohedral phases resemble Bloch-like walls known from magnetism.

description: The eukaryotic genome is organized in three dimensions within the nucleus. Transcriptionally active chromatin is spatially separated from silent heterochromatin, a large fraction of which is located at the nuclear periphery. However, the mechanisms by which chromatin is localized at the nuclear periphery remain poorly understood. Here we demonstrate that Proline Rich 14 (PRR14) protein organizes H3K9me3-modified heterochromatin at the nuclear lamina. We show that PRR14 dynamically associates with both the nuclear lamina and heterochromatin, and is able to reorganize heterochromatin in the nucleus of interphase cells independent of mitosis. We characterize two functional HP1-binding sites within PRR14 that contribute to its association with heterochromatin. We also demonstrate that PPR14 forms an anchoring surface for heterochromatin at the nuclear lamina where it interacts dynamically with HP1-associated chromatin. Our study proposes a model of dynamic heterochromatin organization at the nuclear lamina via the PRR14 tethering protein.
Spectroscopy of the symbiotic star CH Cygni from 1996 to 2007

description: We monitored a set of emission lines in the optical spectra of CH Cyg using the 1.5-m telescope at the Tartu Observatory, Estonia. Most of the spectra were registered in the H alpha region, but other Balmer lines and lines of He, N, O, and Fe were also investigated in terms of their equivalent widths, radial velocities, and absolute fluxes. The spectra indicate different stages that CH Cyg has been through in the course of our observations. During quiescence, the strength of the line profiles changes in opposite phase with the star's luminosity. The H alpha profile becomes double-peaked at times, which may point to the temporary presence of some disk-like structure, but also to absorption in neutral gas surrounding the area of the formation of the emission component. In 1999, when a periastron passage is assumed according to the 5700-day model, the Balmer lines strengthen considerably, as might be expected due to an increase in the accretion rate. The eclipse in 2001, however, is not noticed. At certain episodes, the controversial 756-day period of CH Cyg is seen in our data.

Presolar Diamond in Meteorites

description: Presolar diamond, the carrier of the isotopically anomalous Xe component Xe-HL, was the first mineral type of presolar dust that was isolated from meteorites. The excesses in the light, p-process only isotopes 124Xe and 126Xe, and in the heavy, r-process only isotopes 134Xe and 136Xe relative to the solar ratios indicate that Xe-HL was produced in supernovae: they are the only stellar source where these two processes are believed to take place. Although these processes occur in supernovae, their physical conditions and timeframes are completely different. Yet the excesses are always correlated in diamond separates from meteorites. Furthermore, the p-process 124Xe/126Xe inferred from Xe-L and the r-process 134Xe/136Xe from Xe-H do not agree with the p-process and r-process ratios derived from the solar system abundance, and the inferred p-process ratio does not agree with those predicted from stellar models. The 'rapid separation scenario', where the separation of Xe and its radiogenic precursors Te and I takes place at the very early stage (7900 sec after the end of the r-process), has been proposed to explain Xe-H. Alternatively, mixing of 20% of material that experienced neutron burst and 80% of solar material can reproduce the pattern of Xe-H, although Xe-L is not accounted for with this scenario.

Dynamical Screening in Correlated Electron Materials

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We present an efficient method for incorporating the dynamical effects of the screening of the Hubbard U by electronic degrees of freedom in the solid into the single site dynamical mean field approximation. The formalism is illustrated by model system calculations which capture the essential features of the frequency dependent interactions proposed for Gd, Ni, SrVO_3 and other compounds. Screening leads to shifts in the metal-insulator phase boundary, changes in the spectral function near the Mott-Hubbard gap edge and to a renormalization of the quasiparticle weight. Hubbard bands are generically neither separated by the screened nor the unscreened interaction energy, implying that the common practice of extracting the Hubbard U from the energies of features in photoemission and inverse photoemission spectra requires reexamination.

description: Black soldier fly larvae (BSFL) oil has garnered interest as potential substitute for vegetable oil in feed formulations aimed at enhancing productivity and product quality. This study aimed to investigate the impact of supplementation BSFL oil calcium salt (BSFLO-SCa) on the egg quality and gene expression involved in fat metabolism in laying hens. A total of sixty 40-wk-old ISA Brown laying hens were divided into three distinct groups: a control group (T0) that received a basic diet, and two treatment groups that were supplemented with 1% (T1) and 2% (T2) BSFLO-SCa. Each group consisted of 5 replicates, with 4 laying hens per replicate. The study indicated that inclusion 2% of BSFLO-SCa significantly increased egg albumen weight, height and ratio, eggshell weight, and thickness (P < 0.05). The inclusion 1 and 2% of BSFLO-SCa increased the yolk lightness (L*) and yellowness (b*), but redness (a*) was decreased (P < 0.05). Moreover, BSFLO-SCa supplementation with 1 and 2% reduced (P < 0.05) egg fat and cholesterol. Analysis fatty acid profiles showed significant increased medium chain fatty acid (MCFA) and polyunsaturated fatty acid (PUFA) (P < 0.05), while monosaturated fatty acid (MUFA) reduced (P < 0.05) with 2% BSFLO-SCa. Gene expression related to lipid metabolism, such as fatty acid synthase (FAS) and acetyl-CoA carboxylase (ACC), as well as cholesterol synthesis gene expression of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) were downregulated (P < 0.05). In conclusion, inclusion at 2% of BSFLO-SCa in diet improved the egg quality and reduced fat and cholesterol egg of laying hens. This improvement was accompanied by downregulation of key genes involved in lipid metabolism.

Mass media destabilizes the cultural homogeneous regime in Axelrod's model

description: An important feature of Axelrod's model for culture dissemination or social influence is the emergence of many multicultural absorbing states, despite the fact that the local rules that specify the agents interactions are explicitly designed to decrease the cultural differences between agents. Here we re-examine the problem of introducing an external, global interaction -- the mass media -- in the rules of Axelrod's model: in addition to their nearest-neighbors, each agent has a certain probability $p$ to interact with a virtual neighbor whose cultural features are fixed from the outset. Most surprisingly, this apparently homogenizing effect actually increases the cultural diversity of the population. We show that, contrary to previous claims in the literature, even a vanishingly small value of $p$ is sufficient to destabilize the homogeneous regime for very large lattice sizes.
Application of operations research in the airline industry
Creators: name: Alexander, Arthur
Publisher: name: University of British Columbia
Year: 2011

description: The problem was to review and evaluate operations research techniques and models that had been applied in the airline industry and to discover problem areas where further research is needed. The method was to review management and operations research literature pertaining to airlines, and to formulate the thesis outline on the basis of literature consulted. More specialized literature was then sought under each of the main chapter headings: Marketing, Production, Airports, Finance. In Marketing, little was found that originated from airline companies, except in the area of forecasting. Advertising and pricing models studied were chiefly from manufacturing industries. Airline Production, the revenue-earning part of airline operation, has been extensively studied by operations researchers in the airline industry. Reservations systems, manpower planning, scheduling of aircraft and crews and passenger check-in and baggage handling were main topics of study. Airport models dealing with traffic congestion, Air Traffic Control, aircraft, maintenance, and inventory control have been successfully implemented. Financial models have been developed largely by airframe manufacturers as selling tools for new aircraft, and for market research by the plane builders. Cash flow models and models that aid financial control have been applied. General conclusions are that operations research has been investigated as a means to better airline management in most departments of airline operation. Much remains to be done to develop practical operations research competence in the following areas: 1. Advertising and Pricing. 2. Routing and Scheduling of aircraft and crews. 3. Financial Investment. The volume of the literature on operations research is growing rapidly. This thesis includes only a small sampling of the work done prior to 1971. For more intensive study, bibliographies of current and past work should be consulted. An excellent source of bibliographical data is the International Abstracts in Operations Research, by the International Federation of Operational Research Societies, (IFORS).
Bioethics as Educational Practice Under the Optical of the Morality of Health Professionals: An Integrating Review
Creators: name: Magalhães, Guilherme Lins De

Publisher: name: Zenodo
Year: 2018

description: The article discusses the importance of attention to moral dilemmas in educational practices in health in bioethical context. Displays the ethical argument of Habermas's discussion where the argument must have space in dialogue and the definition of moral strangers coined by Tristram Engelhardt to describe people who defend their worldview, their beliefs and thoughts and at the same time, get to hear reviews and praise. After searching the database LILACS and SciELO were found and analyzed only two scientific articles that contain the descriptors of this work. Unfortunately, the research did not respond to the hypothesis presented in this article: Moral conflicts hinder the educational practice of bioethics in the training of health professionals ?. However, the exercise of this work can encourage research the issue of respect because it is highly relevant topic in the training of health professionals.

description: The argument of this paper is to highlight the gaps that IR theories have in acknowledging the relevance of international cultural relations and dialogue as influential components of increased understanding and cooperation. The paper uses the example of relations between America and Mexico to illustrate that a more holistic view of IR is needed to consider the complexities that existing theories fail to recognise.

description: Digital technologies have revolutionized the business field, offering significant opportunities for small and medium-sized enterprises (SMEs) to enhance sustainability and value creation. This study investigates the impact of digital technology adoption on economic and social value creation, as well as SME performance. Specifically, it examines how social media applications, big data analytics, IoT applications, blockchain applications, and AI-enabled applications influence economic and social value within SMEs. We employed a hybrid approach integrating Structural Equation Modeling (SEM) and Artificial Neural Network (ANN) techniques using SmartPLs 4.0 Application; this research analyzes these relationships. For our analysis, data were collected from 305 SME managers operating in Upper Sindh, Pakistan, specifically from major cities like Sukkur, Larkana, Shikarpur, Jacobabad, and Khairpur. The findings reveal that social media applications, big data analytics, IoT applications, and blockchain applications significantly contribute to both economic and social value creation for SMEs. Conversely, AI-enabled applications show no significant impact on value creation. Importantly, economic and social value creation positively correlates with enhanced SME performance. This study enriches our understanding of how digital technologies influence SMEs in Pakistan, particularly in enhancing economic and social value creation. Through advanced methodologies and rigorous analysis, it bridges theory with practical applications in SMEs’ digital transformation
