Mechanical model for the analysis of liquefaction of horizontal soil deposits
Creators: name: Lee, Kwok Wing
Publisher: name: University of British Columbia
Year: 2010

description: During the development of liquefaction in a soil deposit subjected to vibration there are two processes which work in opposite directions. The volume compaction tendency under cyclic loading causes the pore water pressure to rise, and the dissipation of excess pore water pressure (consolidation) decreases it. Recently, Martin, Finn and Seed (l975) studied the mechanics of pore water pressure generation of a soil sample subjected to cyclic loading and a relation between shear strain cycles, volume compaction and pore water pressure increment was established. A material model based on this relationship is developed in this thesis for saturated granular soil under cyclic simple shear conditions. The model includes a hysteretic stress-strain relationship, volume compaction, pore water pressure rise and dissipation. Using this proposed comprehensive material model, a global mechanical model is constructed to simulate the liquefaction (including consolidation) behavior of a thick horizontal deposit when subjected to horizontal base motion. In this way the coupled problems of dynamic response, pore water pressure rise and consolidation of the deposit under seismic loading can be analysed. The numerical techniques used to solve such problems are discussed in detail. The response of a typical saturated sand deposit under earthquake loading is determined using the proposed model and the results show that the model can predict the various phenomena that saturated sand deposits exhibit during earthquakes. The global model also makes clear the influence of permeability on the liquefaction potential of the soil deposit.

description: The chiral-odd transversity generalized parton distributions (GPDs) of the nucleon can be accessed experimentally through the exclusive photoproduction process gamma + N -> pi + rho + N', in the kinematics where the meson pair has a large invariant mass and the final nucleon has a small transverse momentum, provided the vector meson is produced in a transversally polarized state. We calculate perturbatively the scattering amplitude at leading order in alpha_s. We build a simple model for the dominant transversity GPD H_T(x,xi, t) based on the concept of double distribution. We estimate the unpolarized differential cross section for this process in the kinematics of the Jlab and COMPASS experiments. Counting rates show that the experiment looks feasible with the real photon beam characteristics expected at JLab@12 GeV, and with the quasi real photon beam in the COMPASS experiment.

Inflow and outflow from the accretion disc of the microquasar SS433: UKIRT spectroscopy
Creators: name: Perez, Sebastian
name: Blundell, Katherine M.
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: A succession of near-IR spectroscopic observations, taken nightly throughout an entire cycle of SS433's orbit, reveal (i) the persistent signature of SS433's accretion disc, having a rotation speed of ~500 km/s, (ii) the presence of the circumbinary disc recently discovered at optical wavelengths by Blundell, Bowler and Schmidtobreick (2008) and (iii) a much faster outflow than has previously been measured for the disc wind. From these, we find a much faster accretion disc wind than has noted before, with a terminal velocity of ~1500 km/s. The increased wind terminal velocity results in a mass-loss rate of ~10e-4 M_sun/yr. These, together with the newly (upwardly) determined masses for the components of the SS433 system, result in an accurate diagnosis of the extent to which SS433 has super-Eddington flows. Our observations imply that the size of the companion star is comparable with the semi-minor axis of the orbit which is given by (1-e^2)^(1/2) 40 R_sun, where e is the eccentricity. Our relatively high spectral resolution at these near-IR wavelengths has enabled us to deconstruct the different components that comprise the Brackett-gamma line in this binary system, and their physical origins. With this line dominated throughout our series of observations by the disc wind, and the accretion disc itself being only a minority (~15 per cent) contribution, we caution against use of the unresolved Brackett-gamma line intensity as an "accretion signature" in X-ray binaries or microquasars in any quantitative way.

BMNH 1946.8.6.25. Designated herein. Type locality: Arabian / Persian Gulf, Iran. MorphoBank pictures: M407236–M407250. Paralectotypes. BMNH 1917.3.6.16–17, same locality as the lectotype; BNHM 1946.8.6.34, Kalabagh, Punjab, Pakistan. MorphoBank pictures: M407251–M407267. Distribution. Southern Iran, including islands in the Arabian/Persian Gulf, Bahrain, Qatar, United Arab Emirates and adjacent Saudi Arabia (Fig. 1). Apart from the paralectotype BNHM 1946.8.6.34, the species has been reported from Pakistan by some authors (e.g. Haas & Werner 1969; Khan 2006). The Pakistani range seems to be formed by two disjunct populations – (i) coastal, which might represent an eastern continuation of the range of M. brevirostris s. s. documented in Iran, and (ii) the Punjab population. Unfortunately, we were not able to obtain any Pakistani material for the genetic analyses and we thus cannot confirm whether the Pakistani populations are conspecific with those from the Arabian/Persian Gulf. Khan (2006) noticed the presence of occipital shield in the Punjab population (found also in the paralectotype) which is usually absent in M. brevirostris s. s. and which may indicate a possible distinction of the northern Pakistani population. Notes. The type locality restriction made by Schmidt (1939) to ‘Kalabagh, Punjab’ without designating a lectotype is per se not valid according to the International Code of Zoological Nomenclature, Articles 74.1 and 76.2 (ICZN 1999). The type locality designated herein represents Blanford’s original collection site on the Tumb Island, which is located close to the genetically screened populations (Fig. 1).

Unravelling the Dark Matter - Dark Energy Paradigm
Creators: name: Cahill, Reginald T
Publisher: name: arXiv
Year: 2009
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: The standard LambdaCDM model of cosmology is usually understood to arise from demanding that the Friedmann-Lemaitre-Robertson-Walker (FLRW) metric satisfy the General Relativity dynamics for spacetime metrics. The FLRW data-based dominant parameter values, Omega_Lambda=0.73 and Omega_m=0.27 for the dark energy and dark matter+matter, respectively, are then determined by fitting the supernova red-shift data. However in the pressure-less flat-space case the LambdaCDM model is most easily derived from Newtonian gravity, and which was based on the special case of planetary motion in the solar system. Not surprisingly when extended to galactic rotations and cosmology Newtonian dynamics is found to be wanting, and the fix-up involves introducing dark matter and dark energy, as shown herein. However a different theory of gravity leads to a different account of galactic rotations and cosmology, and does not require dark matter nor dark energy to fit the supernova data. It is shown that fitting the LambdaCDM model to this new model, and so independently of the actual supernova data, requires the LambdaCDM model parameters to be those given above. Hence we conclude that dark energy and dark matter are no more than mathematical artifacts to fix-up limitations of Newtonian gravity. Various other data are also briefly reviewed to illustrate other successful tests of this new theory of gravity.

description: We show that any metacompact Moore space is monotonically metacompact and use that result to characterize monotone metacompactness in certain generalized ordered (GO)spaces. We show, for example, that a generalized ordered space with a sigma-closed-discrete dense subset is metrizable if and only if it is monotonically (countably) metacompact, that a monotonically (countably) metacompact GO-space is hereditarily paracompact, and that a locally countably compact GO-space is metrizable if and only if it is monotonically (countably) metacompact. We give an example of a non-metrizable LOTS that is monotonically metacompact, thereby answering a question posed by S. G. Popvassilev. We also give consistent examples showing that if there is a Souslin line, then there is one Souslin line that is monotonically countable metacompact, and another Souslin line that is not monotonically countably metacompact.

The growing importance of Casimir forces in microelectromechanical systems motivates this subject as a topic for graduate many-body physics courses. To this end, we revisit the Casimir effect using methods common in condensed matter physics. We recover previously derived results and explore the implications of the analogies implicit in this treatment.

description: In this work we present the results of theoretical analysis of the de Haas-van Alphen oscillations in quasi-two-dimensional conductors. We have been studying the effect of the Fermi-liquid correlations of charge carriers on the above oscillations. It was shown that at reasonably low temperatures and weak electron scattering the Fermi-liquid interactions may cause noticeable changes in both amplitude and shape of the oscillations even at realistically small values of the Fermi-liquid parameters. Also, we show that the Fermi-liquid interactions in the system of the charge carriers may cause magnetic instability of a quasi-two-dimensional conductor near the peaks of quantum oscillations in the electron density of states at the Fermi surface, indicating the possibility for the diamagnetic phase transition within the relevant ranges of the applied magnetic fields.

description: It is generally believed that a point defect in graphene gives rise to an impurity state at zero energy and causes a sharp peak in the local density of states near the defect site. We revisit the defect problem in graphene and find the general consensus incorrect. By both analytic and numeric methods, we show that the contribution to the local density of states from the impurity state vanishes in the thermodynamic limit. Instead, the pronounced peak of the zero-bias anomaly is a power-law singularity $1/|E|$ from infinite resonant peaks in the low-energy regime induced by the defect. Our finding shows that the peak shall be viewed as a collective phenomenon rather than a single impurity state in previous studies.

Eremias brevirostris – Boulenger (1921) Eremias brevirostris microlepis – Angel (1936) Mesalina brevirostris microlepis – Szczerbak (1989) Holotype. MNHN 1935.285. Type locality: ‘Haouarine’ [‘à 55 kilomètres au S.­ E. de Homs’], (Syria). MorphoBank pictures: M407268–M407305. Distribution. Lebanon, Syria, northern Jordan and southern Turkey (Fig. 1). Notes. Mesalina microlepis is morphologically very similar to M. bernoullii and, contrary to what Angel (1936) suggested it cannot be distinguished from it by the numbers of dorsal and gular scales, and subdigital lamellae. The only morphological character that discriminates the species is the structure of the lower eyelid window. All specimens of M. microlepis (including the holotype) possess a window consisting of more than three roughly equal semitransparent scales whereas the window of M. bernoullii, M. brevirostris s. s. and the new Saudi species consists of 1–3 larger semitransparent scales (see Fig. 3 in Mayer et al. 2006). Mesalina microlepis and M. bernoullii have been confirmed to occur syntopically in western Syria (Mayer et al. 2006). The presence of M. microlepis in Jordan and Turkey is confirmed based on specimens with similar eyelid window structure (Haas & Werner 1969; Kumlutaş et al. 2002).

description: We confirm our earlier tentative detection of M31* in X-rays and measure its light-curve and spectrum. Observations in 2004-2005 find M31* rather quiescent in the X-ray and radio. However, X-ray observations in 2006-2007 and radio observations in 2002 show M31* to be highly variable at times. A separate variable X-ray source is found near P1, the brighter of the two optical nuclei. The apparent angular Bondi radius of M31* is the largest of any black hole, and large enough to be well resolved with Chandra. The diffuse emission within this Bondi radius is found to have an X-ray temperature ~0.3 keV and density 0.1 cm-3, indistinguishable from the hot gas in the surrounding regions of the bulge given the statistics allowed by the current observations. The X-ray source at the location of M31* is consistent with a point source and a power law spectrum with energy slope 0.9+/-0.2. Our identification of this X-ray source with M31* is based solely on positional coincidence.

description: The recent discovery of a three-planet extrasolar system of HR 8799 by Marois et al. is a breakthrough in the field of the direct imaging. This great achievement raises questions on the formation and dynamical stability of the HR 8799 system, because Keplerian fits to astrometric data are strongly unstable during ~0.2Myr. We search for stable, self-consistent N-body orbits with the so called GAMP method that incorporates stability constraints into the optimization algorithm. Our searches reveal only small regions of stable motions in the phase space of three-planet, coplanar configurations. Most likely, if the planetary masses are in 10-Jupiter-mass range, they may be stable only if the planets are involved in two- or three-body mean motion resonances (MMRs). We found that 80% systems found by GAMP that survived 30Myr backwards integrations, eventually become unstable after 100Myr. It could mean that the HR 8799 system undergo a phase of planet-planet scattering. We test a hypothesis that the less certain detection of the innermost object is due to a blending effect. In such a case, two-planet best-fit systems are mostly stable, on quasi-circular orbits and close to the 5:2 MMR, resembling the Jupiter-Saturn pair.

Threshold pricing in University continuing education
Creators: name: Lamoureux, Marvin Eugene
Publisher: name: University of British Columbia
Year: 2010

description: Three pricing methods: multi-stage, economic and threshold were reviewed relative to continuing education. Because threshold pricing's scope for course price development was so broad, it became this study's purpose to determine if such a pricing method could be applied to continuing education. Three studies were conducted using University of British Columbia Continuing Education data. The first study analyzed 937 courses which either failed to materialize or were conducted. Mean course prices between both groups were not significant. Course price and length interaction as each affected enrolment were also analyzed. Course length, not price, significantly affected enrolment. Centre course prices were therefore "acceptable" to the Centre's participants. A second study analyzed 119 general and professional education course participants to determine threshold pricing attitudes. Although course price thresholds existed for both groups, it was evident that each represented a distinct market. Significant variations in socioeconomic variables and pricing attitudes occurred. A more detailed study was then conducted using another 242 professional education course participants. Hypotheses based on threshold pricing theory were tested. Significant differences existed between the mean price of courses and participant determined upper and lower bound prices. Positive and significant correlations occurred for selected "wealth" and "continuing education commitment" variables, as both variables related to these upper and lower bound prices. Price and imputed quality attitudes about Centre courses were evident with only 8.5% of the participants wanting free courses. Classification of the 242 participants into three participant-determined price-oriented sub-markets ("top dollar", average, low) was statistically accomplished but proved inadequate for marketing decision purposes. All three studies defined beneficial uses for both market segmentation and threshold pricing as each relates to continuing education. It was suggested, however, that further studies be conducted to broaden the scope of these decision techniques.
Measurement of the $\ttbar$ Production Cross Section in 2 fb$^{-1}$ of $\ppbar$ Collisions at $\sqrt{s}=1.96$ TeV Using Lepton Plus Jets Events with Soft Muon b-Tagging

description: We present a measurement of the $\ttbar$ production cross section in $\ppbar$ collisions at $\sqrt{s}=1.96$ TeV using events containing a high transverse momentum electron or muon, three or more jets, and missing transverse energy. Events consistent with $\ttbar$ decay are found by identifying jets containing candidate heavy-flavor semileptonic decays to muons. The measurement uses a CDF Run II data sample corresponding to $2 \mathrm{fb^{-1}}$ of integrated luminosity. Based on 248 candidate events with three or more jets and an expected background of $79.5\pm5.3$ events, we measure a production cross section of $9.1\pm 1.6 \mathrm{pb}$.

description: We perform an update of the next-to-leading order calculation of the rate for Higgs boson production in association with two jets. Our new calculation incorporates the full analytic result for the one-loop virtual amplitude. This new theoretical information allows us to construct a code including the decay of the Higgs boson without incurring a prohibitive penalty in computer running time. Results are presented for the Tevatron, where implications for the Higgs search are sketched, and also for a range of scenarios at the LHC.

description: We study the quark deconfinement phase transition in hot $β$-stable hadronic matter. Assuming a first order phase transition, we calculate the enthalpy per baryon of the hadron-quark phase transition. We calculate and compare the nucleation rate and the nucleation time due to thermal and quantum nucleation mechanisms. We compute the crossover temperature above which thermal nucleation dominates the finite temperature quantum nucleation mechanism. We next discuss the consequences for the physics of proto-neutron stars. We introduce the concept of limiting conversion temperature and critical mass $M_{cr}$ for proto-hadronic stars, and we show that proto-hadronic stars with a mass $M < M_{cr}$ could survive the early stages of their evolution without decaying to a quark star.

description: We investigate transport through a single impurity in metallic zigzag carbon nanotube and find the conductance sensitively depends on the impurity strength and the bias voltage. It is rather interesting that interplay between the current-carrying scattering state and evanescent modes leads to rich phenomena including resonant backward scattering, perfect tunneling and charge accumulations. In addition, we also find a dual relation between the backscattered conductance and the charge accumulation. At the end, relevance to the experiments is discussed.

description: Pseudoholostrophus Nikitsky, 1983 Pseudoholostrophus Nikitsky, 1983: 37.— Type species: Hallomenus klapperichi Pic, 1954 (orig. des.); Nikitsky, 1998: 40; Young and Pollock, 2002: 416. This genus was described by Nikitsky (1983) on the basis of examination of Hallomenus klapperichi Pic, which is now included in, and type species of Pseudoholostrophus. According to Nikitsky (1998), Pseudoholostrophus differs from Holostrophus in its smaller and more weakly emarginate eyes, and the prosternal process not extending behind the posterior edge of the procoxae. Th ere are four species in Pseudoholostrophus (Nikitsky, 1998), two of which are Nearctic (including Canada) in distribution. Th e other two species, P. klapperichi (Pic) and P. chinensis Nikitsky, are known from China. Nikitsky (1998) divided the genus into two subgenera; all species other than P. discolor (Horn) are placed in the nominate subgenus. Holostrophus discolor (Horn) was transferred to Pseudoholostrophus (Holostrophinus) by Nikitsky (1998).

No Transition Disk? Infrared Excess, PAH, H2, and X-rays from the Weak-Lined T Tauri Star DoAr 21

description: We present new high-resolution mid-infrared imaging, high-resolution optical spectroscopy, and Chandra grating X-ray spectroscopy of the weak-lined T Tauri star DoAr 21. DoAr 21 (age < 10^6 yr and mass ~ 2.2 M_sun) is a strong X-ray emitter, with conflicting evidence in the literature about its disk properties. It shows weak but broad H-alpha emission; polarimetric variability; PAH and H2 emission; and a strong, spatially-resolved 24-micron excess in archival Spitzer photometry. Gemini sub-arcsecond-resolution 9--18 micron images show that there is little or no excess mid-infrared emission within 100 AU of the star; the excess emission is extended over several arcseconds, is quite asymmetric, and is bright in the UV-excited 11.3 micron PAH emission feature. A new high-resolution X-ray grating spectrum from Chandra shows that the stellar X-ray emission is very hard and dominated by continuum emission; it is well-fit by a multi-temperature thermal model and shows no evidence of unusually high densities. We argue that the far-ultraviolet emission from the star's transition region is sufficient to excite the observed extended PAH and continuum emission, and that the H2 emission may be similarly extended and excited. This extended emission may be more akin to a small-scale photodissociation region than a protoplanetary disk, highlighting both the very young ages (< 10^6 yr) at which some stars are found without disks, and the extreme radiation environment around even late-type pre--main-sequence stars.

Estimation of the level of anesthesia during surgery by automatic EEG pattern recognition
Creators: name: McEwen, James Allen
Publisher: name: University of British Columbia
Year: 2010

description: The feasibility of developing an automatic electroencephalographic (EEG) pattern recognition system for reliably estimating the level of consciousness of surgical patients during general anesthesia is investigated. An effort was made to establish a valid methodology, by identifying and controlling as many extraneous variables as possible and by ensuring that the work would be relevant to current anesthetic practice. The data base that was established for use in all experimental investigations consists of 938 EEG pattern samples from 72 subjects and three types of anesthesia. Each EEG pattern sample corresponds to one of five possible clinical levels of anesthesia. The use of automatic pattern recognition techniques, in conjunction with heuristic techniques of clinical EEG analysis, to develop spectral and time domain EEG pattern recognition systems is described. All of the initially developed systems extract a small number of heuristically derived features from unknown EEG pattern samples. The classifiers in these systems employ Bayes decision rule under the assumption that the extracted features are statistically independent. A rationale concerning the choice of this particular feature extraction scheme and pattern classification algorithm is presented and discussed. Consideration is given to the general problem of how to use a relatively small set of available EEG pattern samples to effectively evaluate the performance of EEG pattern recognition systems. Two non-parametric techniques which provide particularly informative and efficient estimates of the performance of such systems are formulated. Results obtained by employing these techniques to estimate the performance of the initially developed spectral and time domain EEG pattern recognition systems are presented. The results clearly demonstrate the feasibility of estimating the level of anesthesia by means of automatic EEG pattern recognition. However, the results also indicate that the initially developed systems are not sufficiently reliable for immediate and general clinical application. Theoretical techniques are developed to model some relevant statistical properties of spontaneous EEG activity, with a view to improving the performance of the initially developed EEG pattern recognition systems. Results which were obtained by applying the modelling techniques to some specific ensembles of EEG pattern samples are presented. The comparative advantages of employing alternate methods of EEG analysis are then discussed in relation to the estimated statistical characteristics of the particular EEG ensembles under consideration. Several factors which, could adversely affect the reliable performance of EEG pattern recognition systems in general, and the initially developed systems in particular, are identified and discussed. Various schemes for improving the performance of the initially developed systems are suggested and an evaluation of the practicability of each is presented.
Gravity as an effective theory

description: Using as inspiration the well known chiral effective lagrangian describing the interactions of pions at low energies, in these lectures we review the quantization procedure of Einstein gravity in the spirit of effective field theories. As has been emphasized by several authors, quantum corrections to observables in gravity are, by naive power counting, very small. While some quantities are not predictable (they require local counterterms of higher dimensionality) others, non local, are. A notable example is the calculation of quantum corrections to Newton's law. Albeit tiny these corrections are of considerable theoretical importance, perhaps providing information on the ultaviolet properties of gravity. We then try to search for a situation where these non local corrections may be observable in a cosmological context in the early universe. Having seen that gravity admits an effective treatment similar to the one of pions, we pursue this analogy and propose a two-dimensional toy model where a dynamical zwei-bein is generated from a theory without any metric at all.
