Simulating and visualizing marine oil spills
Creators: name: Van Blankenstein, David
Publisher: name: University of British Columbia
Year: 2008

description: The main goals of this thesis are to develop a system to simulate and visualize the dynamics of a marine oil spill. This necessitates the development of computational models of the properties of petroleum, the containing environment, and a melding of them into a consistent simulation of the fate and transport of oil spills. Techniques of computer graphics will be applied to present the state of this system as a visual output. Through a large set of accessible parameters and data, the variation of the system in terms of spill simulation, and model tuning, will be visualized over both time and space. The resulting system is a combination of research from a spectrum of scientific and technological areas. It provides a means of abstracting the problem of pollution through an accessible and consistent collection of mathematical models, and presents its results for interpretation through visualization. As a practical illustration of the system, it will be tested and verified in the region of southwestern British Columbia.

Comment on "Prediction of lattice constant in cubic perovskites"
Creators: name: Moreira, Roberto L.

Year: 2007

subject: FOS: Physical sciences

description: In a recent work by Jiang et al. [J. Phys. Chem. Solids 67 (2006) 1531-1536], the interrelationship between lattice constant, ionic radii and tolerance factor of cubic perovskites has been established and an empirical equation was obtained. However, the assumption of incorrect ionic coordination led to an incorrect mathematical expression even though the average relative errors between predicted and observed lattice constants of 132 materials were below 1%. Here, corrected coefficients for that empirical expression are obtained, which would likely be useful for investigation of general perovskite materials.
Towards an explanatory division of competence and performance : a language-independent parsing scheme
Creators: name: Alphonce, Carl G.
Publisher: name: University of British Columbia
Year: 2008

description: This dissertation defends in some small measure the thesis that there is a universal parsing model for natural languages. Such a model will apply, without change, cross-linguistically. The defense of this thesis proceeds by finding solutions to some apparently insurmountable problems which arise from the interaction of a set of basic and seemingly uncontroversial assumptions concerning both the linguistic framework and the computational one. Some of the difficulties associated with parsing overtly and covertly derived unbounded A dependencies, as instantiated in English and Chinese in particular, are explored; solutions which are psycholinguistically plausible are presented. In further defense, it is claimed that there are certain linguistic phenomena, such as Relativized Minimality and some curious directional asymmetries in the movement rule move-a, which are better analyzed as artifacts of performance constraints, rather than competence constraints; by removing some of the burden from the competence theory(the syntactic theory, in this case) and placing it on the performance theory (the parsing model), a more perspicuous model of human language-processing emerges. By delimiting more strictly the division between competence and performance in this manner, the adoption of a universal parsing scheme is made possible. This cross-linguistically applicable model makes strong computational and linguistic predictions, which are also explored.

description: Motivated by two seminal models proposed to explain the Universe acceleration, this paper is devoted to study a hybrid model which is constructed through a generalized Chaplygin gas with the addition of a bulk viscosity. We call the model a Viscous Generalized Chaplygin Gas (VGCG) and its free parameters are constrained through several cosmological data like the Observational Hubble Parameter, Type Ia Supernovae, Baryon Acoustic Oscillations, Strong Lensing Systems, HII Galaxies and using Joint Bayesian analysis. In addition, we implement a Om-diagnostic to analyze the VGCC dynamics and its difference with the standard cosmological model. The hybrid model shows important differences when compared with the standard cosmological model. Finally, based on our Joint analysis we find that the VGCG could be an interesting candidate to alleviate the well-known Hubble constant tension.

Η μελέτη της έκφρασης της survivin σε ασθενείς με ΟΜΛ πραγματοποιήθηκε για πρώτη φορά, τόσο σε επίπεδο mRNA, με τη μέθοδο της Real-TimeRT-PCR (στον μυελό των οστών και στο περιφερικό αίμα), όσο και σε πρωτεϊνικό επίπεδο, με την ανοσοενζυμική μέθοδο ELISA.

description: In the present study, survivin expression was detected in all elderly AMLpatients at diagnosis and in complete remission, in both protein and mRNAlevel. Moreover, survivin mRNA levels were found in bone marrow cells of allcontrol individuals, while Real-Time RT-PCR method revealed low mRNA expressionlevels in peripheral blood cells of the control individuals. In bone marrowcells, mRNA expression was significantly lower, compared to control individuals, while in peripheral blood cells, both mRNA and protein levels were significantly higher. In patients in complete remission, both mRNA and protein levels were similar and not significantly different from the levels in control group. High mRNA expression levels in bone marrow cells were significantly correlated with unfavourable karyotype, unfavourable type of FAB classification and secondary AML, while high mRNA levels in peripheral blood cells were significantly correlated with unfavourable karyotype and failure to achieve complete remission. Finally, high serum protein levels were significantly correlated with failure to response in chemotherapy

description: Symmetries, quantum geometries and electronic correlations are among the most important ingredients of condensed matters, and lead to nontrivial phenomena in experiments, for example, non-reciprocal charge transport. Here we report the non-reciprocal charge transport in the intrinsic magnetic topological insulator MnBi2Te4. The current direction relevant resistance is observed at chiral edges, which is magnetically switchable, edge position sensitive and septuple layer number controllable. Applying gate voltage can effectively tune the non-reciprocal resistance. The observation and manipulation of non-reciprocal charge transport indicate the fundamental role of chirality in charge transport of MnBi2Te4, and pave ways to develop van der Waals spintronic devices by chirality engineering.

The rapid recovery of three-dimensional structure from line drawings
Creators: name: Rensink, Ronald Andy
Publisher: name: University of British Columbia
Year: 2008

description: A computational theory is developed that explains how line drawings of polyhedral objects can be interpreted rapidly and in parallel at early levels of human vision. The key idea is that a time-limited process can correctly recover much of the three-dimensional structure of these objects when split into concurrent streams, each concerned with a single aspect of scene structure. The work proceeds in five stages. The first extends the framework of Marr to allow a process to be analyzed in terms of resource limitations. Two main concerns are identified: (i) reducing the amount of nonlocal information needed, and (ii) making effective use of whatever information is obtained. The second stage traces the difficulty of line interpretation to a small set of constraints. When these are removed, the remaining constraints can be grouped into several relatively independent sets. It is shown that each set can be rapidly solved by a separate processing stream, and that co-ordinating these streams can yield a low-complexity "approximation" that captures much of the structure of the original constraints. In particular, complete recovery is possible in logarithmic time when objects have rectangular corners and the scene-to-image projection is orthographic. The third stage is concerned with making good use of the available information when a fixed time limit exists. This limit is motivated by the need to obtain results within a time independent of image content, and by the need to limit the propagation of inconsistencies. A minimal architecture is assumed, viz., a spatiotopic mesh of simple processors. Constraints are developed to guide the course of the process itself, so that candidate interpretations are considered in order of their likelihood. The fourth stage provides a specific algorithm for the recovery process, showing how it can be implemented on a cellular automaton. Finally, the theory itself is tested on various line drawings. It is shown that much of the three-dimensional structure of a polyhedral scene can indeed be recovered in very little time. It also is shown that the theory can explain the rapid interpretation of line drawings at early levels of human vision.

Η ασυμφωνία των αποτελεσμάτων στις περισσότερες μελέτες σχετικά με τη συσχέτιση της αγγειογένεσης ιδιαίτερα με την ΟΜΛ, που περιορισμένα έχει μελετηθεί μέχρι σήμερα, αποτέλεσε το κίνητρο για την διασαφήνιση αυτών των διαφορών. Θεωρήθηκε ότι σ' αυτό θα βοηθούσε ιδιαίτερα, μεταξύ των άλλων μεθόδων και η μέτρηση του mRNA του VEGF στον κυτταρικό πληθυσμό του μυελού των οστών με την μέθοδο της Real Time RT-PCR (Real Time Reverse Transcriptase-PCR). Η μέθοδος αυτή, που εφαρμόσθηκε για πρώτη φορά στην παρούσα διατριβή για την μελέτη των ασθενών με ΟΜΛ, είναι ταχεία, έχει τα πλεονεκτήματα της ακρίβειας και της επαναληψιμότητας και επιπλέον εξασφαλίζει τον ποσοτικό προσδιορισμό του VEGF, ακόμη και ελάχιστων μεταγράφων και όχι μόνο τον ποιοτικό, όπως έγινε σε προηγούμενες μελέτες. Κατά συνέπεια, τα αποτελέσματα που συνάγονται είναι πιο αξιόπιστα και αξιολογήσιμα
description: The purpose of this particular research is the study of angiogenesis on patients with AML in order to clarify whether and to what extend it participates in pathogenesis and prognosis of the disease and in the response of patients in the treatment. As well as to clarify the possible correlation between VEGF expression and hematologic findings and prognostic factors. The discrepancy of the results in many papers according to angiogenesis in AML underlied the main motive for this research. We consider that it would be helpful the measurement of VEGF mRNA in all cell types that resident in the bone marrow with the use of Real Time RT-PCR (Real Time Reverse Transcriptase-PCR) method. This method, which applied for first time in the current research for the study of AML patients, is fast, has the advantage of accuracy and repeatability and also provides the quantification of VEGF, even small number of transcripts. Therefore, the results that connote are more credible and appreciable

description: We prove two basic conjectures on the distribution of the smallest singular value of random n times n matrices with independent entries. Under minimal moment assumptions, we show that the smallest singular value is of order n^{-1/2}, which is optimal for Gaussian matrices. Moreover, we give a optimal estimate on the tail probability. This comes as a consequence of a new and essentially sharp estimate in the Littlewood-Offord problem: for i.i.d. random variables X_k and real numbers a_k, determine the probability P that the sum of a_k X_k lies near some number v. For arbitrary coefficients a_k of the same order of magnitude, we show that they essentially lie in an arithmetic progression of length 1/p.

Communication Technologies Support to Railway Infrastructure and Operations
Creators: name: Sniady, Aleksander
Publisher: name: Department of Photonics Engineering, Technical Univeristy of Denmark

description: GSM-Railways (GSM-R), which is state-of-the-art railway mobile communication technology, is gradually replacing legacy analogue radio systems. Although GSM-R is an unquestionable achievement in terms of European railway interoperability, from a telecommunication point of view, it is an obsolete technology. In the research work presented in this thesis, GSM-R technology is analysed and its main shortcomings are identified, namely: lack of capacity, limited data transmission capabilities, and inefficiency in radio resource usage. Due to these significant disadvantages, alternative mobile technologies are considered to replace GSM-R in the future. This thesis is focused on Long Term Evolution (LTE) as one of the most likely successors to GSM-R. As a technology designed for commercial purposes, LTE has to be investigated specifically in railway environment. Using computer-based simulations, the LTE network is examined in various scenarios modelling typical railway conditions. The transmission performance offered by LTE is analysed under worst-case assumptions in terms of traffic load, base station density, and user speed. The results demonstrate that LTE fulfils transmission requirements set for the two most important railway applications: European Train Control System (ETCS) signalling and railway-specific voice communication. Therefore, LTE is technically capable of replacing GSM-R as the communication network for the European Rail Traffic Management System (ERTMS). Moreover, the simulation results show that LTE offers a significant improvement over GSM-R in terms of transmission capacity and performance. Thus, LTE as a ii railway communication technology would create an opportunity to introduce new business-supporting applications, which could enhance railway operation. The demand for such applications is growing in railways, but the GSM-R networks cannot deliver them. Furthermore, a radio access architecture based on cooperating macro and micro cells is proposed in the thesis. This heterogeneous network architecture, which is novel for railways, may bring numerous advantages, such as high network availability and reduction of inter-cell handover rate for running trains. It also enables railways to use new high-frequency radio bands, which is not a feasible option in the classical railway radio deployments. Simulation results indicate that the macro/micro architecture offers huge capacity increase, which can be used for providing bandwidth-demanding applications, such as video surveillance. All in all, this thesis presents a feasible evolution in the field of railway communications. LTE technology together with the novel heterogeneous architecture may transform railway mobile networks from being a bottleneck of the system into becoming its strong asset.

Constraints from Solar and Reactor Neutrinos on Unparticle Long-Range Forces

description: We have investigated the impact of long-range forces induced by unparticle operators of scalar, vector and tensor nature coupled to fermions in the interpretation of solar neutrinos and KamLAND data. If the unparticle couplings to the neutrinos are mildly non-universal, such long-range forces will not factorize out in the neutrino flavour evolution. As a consequence large deviations from the observed standard matter-induced oscillation pattern for solar neutrinos would be generated. In this case, severe limits can be set on the infrared fix point scale, Lambda_u, and the new physics scale, M, as a function of the ultraviolet (d_UV) and anomalous (d) dimension of the unparticle operator. For a scalar unparticle, for instance, assuming the non-universality of the lepton couplings to unparticles to be of the order of a few per mil we find that, for d_UV=3 and d=1.1, M is constrained to be M > O(10^9) TeV (M > O(10^10) TeV) if Lambda_u= 1 TeV (10 TeV). For given values of Lambda_u and d, the corresponding bounds on M for vector [tensor] unparticles are approximately 100 [3/Sqrt(Lambda_u/TeV)] times those for the scalar case. Conversely, these results can be translated into severe constraints on universality violation of the fermion couplings to unparticle operators with scales which can be accessible at future colliders.

description: G0.253+0.016, aka 'the Brick', is one of the most massive (> 10^5 Msun) and dense (> 10^4 cm-3) molecular clouds in the Milky Way's Central Molecular Zone. Previous observations have detected tentative signs of active star formation, most notably a water maser that is associated with a dust continuum source. We present ALMA Band 6 observations with an angular resolution of 0.13" (1000 AU) towards this 'maser core', and report unambiguous evidence of active star formation within G0.253+0.016. We detect a population of eighteen continuum sources (median mass ~ 2 Msun), nine of which are driving bi-polar molecular outflows as seen via SiO (5-4) emission. At the location of the water maser, we find evidence for a protostellar binary/multiple with multi-directional outflow emission. Despite the high density of G0.253+0.016, we find no evidence for high-mass protostars in our ALMA field. The observed sources are instead consistent with a cluster of low-to-intermediate-mass protostars. However, the measured outflow properties are consistent with those expected for intermediate-to-high-mass star formation. We conclude that the sources are young and rapidly accreting, and may potentially form intermediate and high-mass stars in the future. The masses and projected spatial distribution of the cores are generally consistent with thermal fragmentation, suggesting that the large-scale turbulence and strong magnetic field in the cloud do not dominate on these scales, and that star formation on the scale of individual protostars is similar to that in Galactic disc environments.

description: Sharp fronts observed by Chandra satellite between dense cool cluster cores moving with near-sonic velocity through the hotter intergalactic gas, require strong suppression of thermal conductivity across the boundary. This may be due to magnetic fields tangential to the contact surface separating two plasma components. We point out that a super-Alfvenic motion of a plasma cloud (a core of a merging galaxy) through a weakly magnetized intercluster medium leads to "magnetic draping", formation of a thin, strongly magnetized boundary layer with a tangential magnetic field. For supersonic cloud motion, M_s > 1, magnetic field inside the layer reaches near-equipartition values with thermal pressure. Typical thickness of the layer is L /M_A^2 << L, where L is the size of the obstacle (plasma cloud) moving with Alfven Mach number M_A >> 1. To a various degree, magnetic draping occurs both for sub- and supersonic flows, random and ordered magnetic fields and it does not require plasma compressibility. The strongly magnetized layer will thermally isolate the two media and may contribute to the Kelvin-Helmholtz stability of the interface. Similar effects occur for radio bubbles, quasi-spherical expanding cavities blown up by AGN jets; in this case the thickness of the external magnetized layer is smaller, L /M_A^3 << L.

description: A comprehensive study has been performed to estimate the kaon to pion ($K^\pm$/$π^\pm$) yield ratio and total kaon to total pion ($K$/$π$) yield ratio as a function of centre of mass energy in $pp$ collisions at different energies i.e., \sqrts~= 6.3, 17.3, 62.4, 200, 900 GeV, 2.76 TeV, 7 TeV, 13 TeV and 14 TeV using EPOS1.99, EPOS-LHC, HIJING, QGSJETII-03 and Sibyll2.3d model simulations. NA61/SHINE experiment reported that $K^+/π^+$ yield ratio exhibits rapid changes at the SPS energy range. A horn like structure appears in $K/π$ yield ratio as a function of collision energy. Significant presence of horn in $K^+$/$π^+$ and $K^-$/$π^-$ yield ratio is suggested by experimental data at lower energies, which is confirmed by HIJING and EPOS-LHC models. A smooth increase in $K/π$ yield ratio is also seen at higher energies. The model simulations predict similar increase in yield ratio with increasing energies. On the basis of previous available measurements, we also study model predictions of these yield ratios at \sqrts~= 13 and 14 TeV where no data is available. Almost all models suggest a saturation in the yield ratio within statistical fluctuations at these energies except EPOS1.99 and QGSJETII-03 which slightly over predict the yield ratio. These systematic comparisons are helpful to apply possible constraints on various hadronic event generators to significantly improve the predictions of Standard Model physics as well as for the understanding of underlying physics mechanisms in high energy collisions.

description: The Event Horizon Telescope (EHT) has imaged the shadow of the supermassive black hole in M87. A library of general relativistic magnetohydrodynamics (GMRHD) models was fit to the observational data, providing constraints on black hole parameters. We investigate how much better future experiments can realistically constrain these parameters and test theories of gravity. We generate realistic synthetic 230 GHz data from representative input models taken from a GRMHD image library for M87, using the 2017, 2021, and an expanded EHT array. The synthetic data are run through a data reduction pipeline used by the EHT. Additionally, we simulate observations at 230, 557, and 690 GHz with the Event Horizon Imager (EHI) Space VLBI concept. Using one of the EHT parameter estimation pipelines, we fit the GRMHD library images to the synthetic data and investigate how the black hole parameter estimations are affected by different arrays and repeated observations. Repeated observations play an important role in constraining black hole and accretion parameters as the varying source structure is averaged out. A modest expansion of the EHT already leads to stronger parameter constraints. High-frequency observations from space rule out all but ~15% of the GRMHD models in our library, strongly constraining the magnetic flux and black hole spin. The 1$σ$ constraints on the black hole mass improve by a factor of five with repeated high-frequency space array observations as compared to observations with the current ground array. If the black hole spin, magnetization, and electron temperature distribution can be independently constrained, the shadow size for a given black hole mass can be tested to ~0.5% with the EHI, which allows tests of deviations from general relativity. High-precision tests of the Kerr metric become within reach from observations of the Galactic Center black hole Sagittarius A*.

Some new results on constructing optimal alphabetic binary trees
Creators: name: Mumey, Brendan M.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis studies the question of whether optimal alphabetic binary trees can be constructed in o(n lg n) time. Hu and Tucker [1] gave the first subquadratic algorithm in 1971, namely an O(n lg n) time algorithm. Optimal alphabetic binary trees have many applications and the question of whether an o(n lg n) time algorithm exists has remained an open problem in data structures for the last 20 years. We show that a class of techniques for finding optimal alphabetic trees which includes all current methods yielding O(n lg n) time algorithms are at least as hard as sorting in whatever model of computation used. We introduce a new idea for finding optimal alphabetic binary trees which we refer to as region-processing. Region-processing methods have been successfully used to give O(n) time algorithms for the case where all the input weights are within a constant factor of one another and when they are exponentially separated. Although the region based method we give exhibits o(n lg n) time performance for many cases, we also show a reduction from sorting to it as well. It is possible that the ideas used in this reduction can be extended to yield a general ω(n) lower bound.
Barchan dune corridors: field characterization and investigation of control parameters

description: The structure of the barchan field located between Tarfaya and Laayoune (Atlantic Sahara, Morocco) is quantitatively investigated and compared to that in La Pampa de la Joya (Arequipa, Peru). On the basis of field measurements, we show how the volume, the velocity and the output sand flux of a dune can be computed from the value of its body and horn widths. The dune size distribution is obtained from the analysis of aerial photographs. It shows that these fields are in a statistically homogeneous state along the wind direction and present a `corridor' structure in the transverse direction, in which the dunes have a rather well selected size. Investigating the possible external parameters controlling these corridors, we demonstrate that none among topography, granulometry, wind and sand flux is relevant. We finally discuss the dynamical processes at work in these fields (collisions and wind fluctuations), and investigate the way they could regulate the size of the dunes. Furthermore we show that the overall sand flux transported by a dune field is smaller than the maximum transport that could be reached in the absence of dunes, i.e. in saltation over the solid ground.

Nearly Tri-bimaximal Neutrino Mixing and CP Violation from mu-tau Symmetry Breaking

description: Assuming the Majorana nature of massive neutrinos, we generalize the Friedberg-Lee neutrino mass model to include CP violation in the neutrino mass matrix $M^{}_ν$. We show that a favorable neutrino mixing pattern (with $θ^{}_{12} \approx 35.3^\circ$, $θ^{}_{23} = 45^\circ$, $θ^{}_{13} \neq 0^\circ$ and $δ= 90^\circ$) can naturally be derived from $M^{}_ν$, if it has an approximate or softly-broken $μ$-$τ$ symmetry. We point out a different way to obtain the nearly tri-bimaximal neutrino mixing with $δ= 0^\circ$ and non-vanishing Majorana phases. The most general case, in which all the free parameters of $M^{}_ν$ are complex and the resultant neutrino mixing matrix contains both Dirac and Majorana phases of CP violation, is also discussed.

Weak Lensing of the Cosmic Microwave Background by Foreground Gravitational Waves

description: Weak lensing distortion of the background cosmic microwave background (CMB) temperature and polarization patterns by the foreground density fluctuations is well studied in the literature. We discuss the gravitational lensing modification to CMB anisotropies and polarization by a stochastic background of primordial gravitational waves between us and the last scattering surface. While density fluctuations perturb CMB photons via gradient-type deflections only, foreground gravitational waves distort CMB anisotropies via both gradient- and curl-type displacements. The latter is a rotation of background images, while the former is related to the lensing convergence. For a primordial background of inflationary gravitational waves, with an amplitude corresponding to a tensor-to-scalar ratio below the current upper limit of $\sim$ 0.3, the resulting modifications to the angular power spectra of CMB temperature anisotropy and polarization are below the cosmic variance limit. At tens of arcminute angular scales and below, these corrections, however, are above the level at which systematics must be controlled in all-sky anisotropy and polarization maps with no instrumental noise and other secondary and foreground signals.

Luminosity Indicators in the Ultraviolet Spectra of Type Ia Supernovae

description: We present a complete sample of International Ultraviolet Explorer and Hubble Space Telescope ultraviolet (UV) spectra of Type Ia supernovae (SNe Ia) through 2004. We measure the equivalent width (EW) and blueshifted velocity of the minimum of the one strong UV feature, Fe II 3250. We also quantify the slope of the near-UV spectra using a new parameter, the ``UV ratio.'' We find that the velocity of the Fe II line does not correlate with light-curve shape, while the EW shows distinct behavior for the slow and fast-declining objects. Using precise Cepheid and surface brightness fluctuation distance measurements of 6 objects with UV spectra observed near maximum light (a total of 12 spectra), we determine that the UV ratio at maximum light is highly correlated with SN Ia luminosity. A larger sample of UV spectra is necessary to increase the statistical certainty of these luminosity indicators and whether they can be combined with light-curve shape to improve measured SN Ia distances.

Pressure-tuning of the c-f hybridization in Yb metal detected by infrared spectroscopy up to 18 GPa

description: It has been known that the elemental Yb, a divalent metal at mbient pressure, becomes a mixed-valent metal under external pressure, with its valence reaching ~2.6 at 30 GPa. In this work, infrared spectroscopy has been used to probe the evolution of microscopic electronic states associated with the valence crossover in Yb at external pressures up to 18 GPa. The measured infrared reflectivity spectrum R(w) of Yb has shown large variations with pressure. In particular, R(w) develops a deep minimum in the mid-infrared, which shifts to lower energy with increasing pressure. The dip is attributed to optical absorption due to a conduction c-f electron hybridization state, similarly to those previously observed for heavy fermion compounds. The red shift of the dip indicates that the $c$-$f$ hybridization decreases with pressure, which is consistent with the increase of valence.
