description: We investigate the use of Malliavin calculus in order to calculate the Greeks of multidimensional complex path-dependent options by simulation. For this purpose, we extend the formulas employed by Montero and Kohatsu-Higa to the multidimensional case. The multidimensional setting shows the convenience of the Malliavin Calculus approach over different techniques that have been previously proposed. Indeed, these techniques may be computationally expensive and do not provide flexibility for variance reduction. In contrast, the Malliavin approach exhibits a higher flexibility by providing a class of functions that return the same expected value (the Greek) with different accuracies. This versatility for variance reduction is not possible without the use of the generalized integral by part formula of Malliavin Calculus. In the multidimensional context, we find convenient formulas that permit to improve the localization technique, introduced in Fournié et al and reduce both the computational cost and the variance. Moreover, we show that the parameters employed for variance reduction can be obtained \textit{on the flight} in the simulation. We illustrate the efficiency of the proposed procedures, coupled with the enhanced version of Quasi-Monte Carlo simulations as discussed in Sabino, for the numerical estimation of the Deltas of call, digital Asian-style and Exotic basket options with a fixed and a floating strike price in a multidimensional Black-Scholes market.

description: We apply the phase field crystal model to study the structure and energy of symmetric tilt grain boundaries of bcc iron in 3D. The parameters for the model are obtained by using a recently developed eight-order fitting scheme [A. Jaatinen et al., Phys. Rev. B 80, 031602 (2009)]. The grain boundary free energies we obtain from the model are in good agreement with previous results from molecular dynamics simulations and experiments.

description: We present a catalogue of galaxy groups and clusters selected using a friends-of-friends algorithm with a dynamic linking length from the 2dF-SDSS and QSO (2SLAQ) luminous red galaxy survey. The linking parameters for the code are chosen through an analysis of simulated 2SLAQ haloes. The resulting catalogue includes 313 clusters containing 1,152 galaxies. The galaxy groups and clusters have an average velocity dispersion of sigma_v = 467.97 km/s and an average size of R_clt = 0.78 Mpc/h. Galaxies from regions of one square degree and centred on the galaxy clusters were downloaded from the Sloan Digital Sky Survey Data Release 6 (SDSS DR6). Investigating the photometric redshifts and cluster red-sequence of these galaxies shows that the galaxy clusters detected with the FoF algorithm are reliable out to z~0.6. We estimate masses for the clusters using their velocity dispersions. These mass estimates are shown to be consistent with 2SLAQ mock halo masses. Further analysis of the simulation haloes shows that clipping out low richness groups with large radii improves the purity of catalogue from 52% to 88%, while retaining a completeness of 94%. Finally, we test the two-point correlation function of our cluster catalogue. We find a best-fitting power law model with parameters r0 = 24\pm4 Mpc/h and gamma = -2.1\pm 0.2, which are in agreement with other low redshift cluster samples and consistent with a ΛCDM universe.

An evaluation of the North American Regional Reanalysis precipitation fields in a topographically complex domain, British Columbia, Canada
Creators: name: Hunter, Cameron
Publisher: name: University of British Columbia
Year: 2016

description: The accuracy of gridded precipitation products in mountainous environments has been shown to be unreliable compared to other geographic areas due to the complex terrain and sparse network of stations typically found in these regions. This study is an analysis of the accuracy of the North American Regional Reanalysis (NARR) precipitation dataset for the province of British Columbia. Unlike similar gridded precipitation products, the NARR has not yet been evaluated to determine how reliably it reproduces observed patterns of precipitation in this region. The objective of this study is to assess the temporal and spatial patterns of precipitation in the NARR record in order to determine how closely it reproduces observed precipitation. A comparison of the NARR precipitation records with station precipitation records was conducted to evaluate the NARR’s ability to reproduce the interannual, monthly, and daily patterns of precipitation experienced. Streamflow records and NARR precipitation records for a number of basins throughout British Columbia were examined using a water balance approach to better understand the spatial variability of errors. A structural break in the NARR data was observed in 2003, which led to larger inaccuracies in the NARR record in subsequent years. This break was caused by a decision to exclude Canadian rain gauge data from the NARR’s data assimilation process from 2003 onwards. Several clear spatial patterns were observed in the NARR precipitation data. The NARR underpredicted precipitation in mountainous regions due to inaccuracies in its digital elevation model (DEM). The NARR overpredicted precipitation in the northern region of BC’s Interior Plateau due to a lack of available rain gauge data in this area. Finally, the NARR was found to be more accurate at modelling precipitation in areas with flat terrain and adequate station coverage, such as the southern region of the Interior and the Northeast Plateau. This analysis has shown the spatial and temporal variability of errors in the NARR dataset, allowing users to recognize both the strengths and potential shortcomings of this tool.

description: We investigate a system of fermions on a two-dimensional optical square lattice in the strongly repulsive coupling regime. In this case, the interactions can be controlled by laser intensity as well as by Feshbach resonance. We compare the energetics of states with resonating valence bond d-wave superfluidity, antiferromagnetic long range order and a homogeneous state with coexistence of superfluidity and antiferromagnetism. We show that the energy density of a hole $e_{hole}(x)$ has a minimum at doping $x=x_c$ that signals phase separation between the antiferromagnetic and d-wave paired superfluid phases. The energy of the phase-separated ground state is however found to be very close to that of a homogeneous state with coexisting antiferromagnetic and superfluid orders. We explore the dependence of the energy on the interaction strength and on the three-site hopping terms and compare with the nearest neighbor hopping {\it t-J} model.

description: The neuromagnetic activity (magnetoencephalogram, MEG) from healthy human brain and from an epileptic patient against chromatic flickering stimuli has been earlier analyzed on the basis of a memory functions formalism (MFF). Information measures of memory as well as relaxation parameters revealed high individuality and unique features in the neuromagnetic brain responses of each subject. The current paper demonstrates new capabilities of MFF by studying cross-correlations between MEG signals obtained from multiple and distant brain regions. It is shown that the MEG signals of healthy subjects are characterized by well-defined effects of frequency synchronization and at the same time by the domination of low-frequency processes. On the contrary, the MEG of a patient is characterized by a sharp abnormality of frequency synchronization, and also by prevalence of high-frequency quasi-periodic processes. Modification of synchronization effects and dynamics of cross-correlations offer a promising method of detecting pathological abnormalities in brain responses.

Morse Theory for Geodesics in Conical Manifolds

Publisher: name: arXiv
Year: 2010
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: The aim of this paper is to extend the Morse theory for geodesics to the conical manifolds. We define these manifolds as submanifolds of $\R^n$ with a finite number of conical singularities. To formulate a good Morse theory we must use an appropriate definition of geodesic. The main theorem of this paper claims that, although the energy is nonsmooth, we can find a continuous retraction of its sublevels in absence of critical points. So, we can give a good definition of index for isolated critical values and for isolated critical points. We prove that Morse relations hold and, at last, we give a definition of multiplicity of geodesics which is geometrical meaningful.

Finally, it follows that the prescribed models derive the acceleration of the universe.

Gender differences in pain-physical activity linkages among older adults : lessons learned from daily life approaches
Creators: name: Ho, Amy
Publisher: name: University of British Columbia
Year: 2016

description: Many older adults know about the health benefits of an active lifestyle, but frequently, pain prevents them from engaging in physical activity. The majority of older adults experience pain, which is a complex experience that can vary across time and is shaped by sociocultural factors such as gender. The objectives of this study are twofold: first, to describe the time- varying associations between daily pain and physical activity, and second to explore differences in these associations between women and men. One hundred and twenty eight community dwelling older adults aged 65 years and older were asked to report their pain levels three times daily over a 10-day period. For the same period, participants wore an accelerometer to objectively capture their daily physical activity (step counts; minutes of moderate to vigorous physical activity). Findings indicate that increased daily pain was associated with increased daily step counts and minutes of moderate to vigorous physical activity especially among older women. Secondly, confirming past literature and contrasting daily pain reports, overall pain levels across the study period were negatively associated with minutes of moderate to vigorous physical activity. Findings highlight that pain is significantly associated with physical activity in old age. The nature of this association depends on the time-scale that is considered and it differs between women and men. There is a need to pay more attention to those that are particularly vulnerable pain experience, to ensure both older men and women have an equal opportunity to engage in and benefit from physical activity.

description: To derive carbon isotopic ratios from optically thin tracers in the central regions of the starburst galaxies M82 and NGC253. We present high sensitivity observations of CCH and two of its 13C isotopologues, C13CH and 13CCH, as well as the optically thin emission from C18O and 13C18O. We assume the column density ratio between isotopologues is representative of the 12C13C isotopic ratio. From CCH, lower limits to the 12C/13C isotopic ratio of 138 in M82, and 81 in NGC253, are derived. Lower limits to the 12C/13C ratios from CO isotopologues support these. 13C18O is tentatively detected in NGC253, which is the first reported detection in the extragalactic ISM. Based on these limits, we infer ratios of 16O/18O>350 and >300 in M82 and NGC253, respectively, and 32S/34S>16 in NGC253. and the H2 column density determination through the optically thin tracers 13CO and C18O.

description: To date the search for habitable Earth-like planets has primarily focused on nuclear burning stars. I propose that this search should be expanded to cool white dwarf stars that have expended their nuclear fuel. I define the continuously habitable zone of white dwarfs, and show that it extends from ~0.005 to 0.02 AU for white dwarfs with masses from 0.4 to 0.9 solar masses, temperatures less than 10,000 K, and habitable durations of at least 3 Gyr. As they are similar in size to Earth, white dwarfs may be deeply eclipsed by terrestrial planets that orbit edge-on, which can easily be detected with ground-based telescopes. If planets can migrate inward or reform near white dwarfs, I show that a global robotic telescope network could carry out a transit survey of nearby white dwarfs placing interesting constraints on the presence of habitable Earths. If planets were detected, I show that the survey would favor detection of planets similar to Earth: similar size, temperature, rotation period, and host star temperatures similar to the Sun. The Large Synoptic Survey Telescope could place even tighter constraints on the frequency of habitable Earths around white dwarfs. The confirmation and characterization of these planets might be carried out with large ground and space telescopes.

Energy efficient video sensor networks for surveillance applications
Creators: name: Sarif, Bambang Ali Basyah
Publisher: name: University of British Columbia
Year: 2016

description: Video sensor networks (VSNs) provide rich sensing information and coverage, both beneficial for applications requiring visual information such as smart homes, traffic control, healthcare systems and monitoring/surveillance systems. Since a VSN-based surveillance application is usually assumed to have limited resources, energy efficiency has become one of the most important design aspects of such networks. However, unlike common sensor network platforms, where power consumption mostly comes from the wireless transmission, the encoding process in a video sensor network contributes to a significant portion of the overall power consumption. There is a trade-off between encoding complexity and bitrate in a sense that in order to increase compression performance, i.e., achieve a lower bitrate, a more complex encoding process is necessary. The coding complexity and video bitrate determine the overall encoding and transmission power consumption of a VSN. Thus, choosing the right configuration and setting parameters that lead to optimal encoding performance is of primary importance for controlling power consumption in VSNs. The coding complexity and bitrate also depend on the video content complexity, as spatial details and high motion tend to lead to higher computation costs or increased bitrates. In a video surveillance network, each node captures an event from a different point of view, such that each captured video stream has unique spatial and temporal information. This thesis investigates the trade-off between encoding complexity and communication power consumption in a video surveillance network where the effect of video encoding parameters, content complexity, and network topology are taken into consideration. In order to take into account the effect of content complexity, we created a video surveillance dataset consisting of a large number of captured videos with different levels of spatial information and motion. Then, we design an algorithm that minimizes the video surveillance network’s power consumption for different scene settings. Models that estimate the coding complexity and bitrate were proposed. Finally, these models were used to minimize the video surveillance network’s power consumption and estimate the encoding parameters per each node that yield the minimum possible power consumption for the entire network.

description: (abridged) The massive black hole at the center of the Milky Way, SagittariusA* is, in relative terms, the weakest accreting black hole accessible to observations. At the moment, the mean SED of SgrA* is only known reliably in the radio to mm regimes. The goal of this paper is to provide constraints on the mean emission from SgrA* in the near-to-mid infrared. Excellent imaging quality was reached in the MIR by using speckle imaging combined with holographic image reconstruction, a novel technique for this kind of data. No counterpart of SgrA* is detected at 8.6 microns. At this wavelength, SgrA* is located atop a dust ridge, which considerably complicates the search for a potential point source. An observed 3 sigma upper limit of ~10 mJy is estimated for the emission of SgrA* at 8.6 microns, a tighter limit at this wavelength than in previous work. The de-reddened 3 sigma upper limit, including the uncertainty of the extinction correction, is ~84 mJy . Based on the available data, it is argued that, with currently available instruments, SgrA* cannot be detected in the MIR, not even during flares. At 4.8 and 3.8 microns, on the other hand, SgrA* is detected at all times, at least when considering timescales of a few up to 13 min. We derive well-defined time-averaged, de-reddened flux densities of 3.8+-1.3 mJy at 4.8 microns and 5.0+-0.6 mJy at 3.8 microns. Observations with NIRC2/Keck and NaCo/VLT from the literature provide good evidence that SgrA* also has a fairly well-defined de-reddened mean flux of 0.5-2.5 mJy at wavelengths of 2.1-2.2 microns. We present well-constrained anchor points for the SED of SgrA* on the high-frequency side of the Terahertz peak. The new data are in general agreement with published theoretical SEDs of the mean emission from SgrA*, but we expect them to have an appreciable impact on the model parameters in future theoretical work.

description: Type-IIn supernovae (SNe), which are characterized by strong interaction of their ejecta with the surrounding circumstellar matter (CSM), provide a unique opportunity to study the mass-loss history of massive stars shortly before their explosive death. We present the discovery and follow-up observations of a Type IIn SN, PTF 09uj, detected by the Palomar Transient Factory (PTF). Serendipitous observations by GALEX at ultraviolet (UV) wavelengths detected the rise of the SN light curve prior to the PTF discovery. The UV light curve of the SN rose fast, with a time scale of a few days, to a UV absolute AB magnitude of about -19.5. Modeling our observations, we suggest that the fast rise of the UV light curve is due to the breakout of the SN shock through the dense CSM (n~10^10 cm^-3). Furthermore, we find that prior to the explosion the progenitor went through a phase of high mass-loss rate (~0.1 solar mass per year) that lasted for a few years. The decay rate of this SN was fast relative to that of other SNe IIn.

Creators: name: Hammarberg, Elin
Publisher: name: Karlsruhe
Year: 2008

description: In this work, a microwave-assisted polyol synthesis was developed, with which low-agglomerated suspensions of crystalline TCO (transparent conductive oxide) nanomaterials could be achieved. As-prepared ITO (indium tin oxide) turned out to be highly conductive. Doped ZnO, SnO2, and Zn-In-O were highly conductive after thermal treatment. Solid state NMR spectroscopy was applied to characterize ZnO:Al and SnO2:F. In addition, a phase transfer of synthesized indium nanoparticles was demonstrated.

Observations of the young supernova remnant RX J1713.7-3946 with the Fermi Large Area Telescope

description: We present observations of the young Supernova remnant (SNR) RX J1713.7-3946 with the Fermi Large Area Telescope (LAT). We clearly detect a source positionally coincident with the SNR. The source is extended with a best-fit extension of 0.55$^{\circ} \pm 0.04^{\circ}$ matching the size of the non-thermal X-ray and TeV gamma-ray emission from the remnant. The positional coincidence and the matching extended emission allows us to identify the LAT source with the supernova remnant RX J1713.7-3946. The spectrum of the source can be described by a very hard power-law with a photon index of $Γ= 1.5 \pm 0.1$ that coincides in normalization with the steeper H.E.S.S.-detected gamma-ray spectrum at higher energies. The broadband gamma-ray emission is consistent with a leptonic origin as the dominant mechanism for the gamma-ray emission.

description: We perform the analysis of the trispectrum of curvature perturbations generated by the interactions characterizing a general theory of single-field inflation obtained by effective field theory methods. We find that curvature-generated interaction terms, which can in general give an important contribution to the amplitude of the four-point function, show some new distinctive features in the form of their trispectrum shape-function. These interesting interactions are invariant under some recently proposed symmetries of the general theory and, as shown explicitly, do allow for a large value of the trispectrum.

Non-Canonical Phase-Space Noncommutativity and the Kantowski-Sachs singularity for Black Holes

description: We consider a cosmological model based upon a non-canonical noncommutative extension of the Heisenberg-Weyl algebra to address the thermodynamical stability and the singularity problem of both the Schwarzschild and the Kantowski-Sachs black holes. The interior of the black hole is modelled by a noncommutative extension of the Wheeler-DeWitt equation. We compute the temperature and entropy of a Kantowski-Sachs black hole and compare our results with the Hawking values. Again, the noncommutativity in the momenta sector allows us to have a minimum in the potential, which is relevant in order to apply the Feynman-Hibbs procedure. For Kantowski-Sachs black holes, the same model is shown to generate a non-unitary dynamics, predicting vanishing total probability in the neighborhood of the singularity. This result effectively regularizes the Kantowski-Sachs singularity and generalizes a similar result, previously obtained for the case of Schwarzschild black hole.

description: We investigate the production of beyond-the-standard-model color-sextet vector bosons at the Large Hadron Collider and their decay into a pair of same-sign top quarks. We demonstrate that the energy of the charged lepton from the top quark semi-leptonic decay serves as a good measure of the top-quark polarization, which, in turn determines the quantum numbers of the boson and distinguishes vector bosons from scalars.
Combinatorial aspects of spatial mixing and new conditions for pressure representation
Creators: name: Briceño Domínguez, Raimundo José
Publisher: name: University of British Columbia
Year: 2016

description: Over the last few decades, there has been a growing interest in a measure-theoretical property of Gibbs distributions known as strong spatial mixing (SSM). SSM has connections with decay of correlations, uniqueness of equilibrium states, approximation algorithms for counting problems, and has been particularly useful for proving special representation formulas and the existence of efficient approximation algorithms for (topological) pressure. We look into conditions for the existence of Gibbs distributions satisfying SSM, with special emphasis in hard constrained models, and apply this for pressure representation and approximation techniques in Z^d lattice models. Given a locally finite countable graph G and a finite graph H, we consider Hom(G,H) the set of graph homomorphisms from G to H, and we study Gibbs measures supported on Hom(G,H). We develop some sufficient and other necessary conditions on Hom(G,H) for the existence of Gibbs specifications satisfying SSM (with exponential decay). In particular, we introduce a new combinatorial condition on the support of Gibbs distributions called topological strong spatial mixing (TSSM). We establish many useful properties of TSSM for studying SSM on systems with hard constraints, and we prove that TSSM combined with SSM is sufficient for having an efficient approximation algorithm for pressure. We also show that TSSM is, in fact, necessary for SSM to hold at high decay rate. Later, we prove a new pressure representation theorem for nearest-neighbour Gibbs interactions on Z^d shift spaces, and apply this to obtain efficient approximation algorithms for pressure in the Z² (ferromagnetic) Potts, (multi-type) Widom-Rowlinson, and hard-core lattice gas models. For Potts, the results apply to every inverse temperature except the critical. For Widom-Rowlinson and hard-core lattice gas, they apply to certain subsets of both the subcritical and supercritical regions. The main novelty of this work is in the latter, where SSM cannot hold.

Formation of Multiple Populations in Globular Clusters: constraints on the dilution by pristine gas

description: The star-to-star differences in the abundance of light elements observed in the globular clusters (GCs) can be explained assuming that a second generation (SG) of stars form in the gas ejected by the asymptotic giant branch (AGB) stars belonging to a first stellar generation. However, while Na and O appear to be anticorrelated in the cluster stars, from the stellar models they turn out to be correlated into the AGB ejecta. In order to reconcile the stellar theory with the observational findings, all the GC models invoke an early dilution of AGB ejecta with pristine gas occurring during the SG formation. Despite a vast consensus about the occurrence of such dilution, the physical process behind it is still unknown. In the present paper we set some general constraints on the pristine gas dynamics and on the possible amount of pristine gas involved in the SG formation, making use of a one zone chemical model. We find that such a dilution is a necessary ingredient in the SG star formation to explain the observed abundance patterns. We confirm the conclusion of our previous works showing that clusters must have been initially much more massive. We also show that models assuming that clusters had an initial mass similar to their current one, and adopting a large fraction of pristine gas to form SG stars, fail to reproduce the observed Na-O anticorrelation and are not viable. We finally show that the dilution event should be restricted in time, rather than extended for the all duration of the SG formation.

Phenomenological markers of future psychosis : the role of cannabis
Creators: name: Brooks, Gabriel
Publisher: name: University of British Columbia
Year: 2016

description: Cannabis use is a known risk factor for the development of psychosis, although the precise nature of this relationship is unclear. The phenomenological experiences associated with cannabis use vary dramatically, and for some resemble certain features of psychosis. We hypothesized that individuals who report particularly unusual experiences associated with cannabis use demonstrate similar electrophysiological patterns to those who score high on schizotypal personality traits. The Cannabis Experiences Questionnaire (CEQ) and the Schizotypal Personality Questionnaire (SPQ) were used to measure these experiences and traits. A sample of 97 individuals were placed into one of five groups: high CEQ scorers (High CEQ), high SPQ scorers (High SPQ), high CEQ and SPQ scorers (High on Both), average CEQ and SPQ scorers (Average Users), and average SPQ non-users (Average Non-Users). Participants completed a visual task in which they indicated whether they saw a face embedded within a static field. Electroencephalography was used to measure the neural response to the stimuli. The N170 event-related potential (ERP) was used to measure perceptual encoding of the stimulus. The High SPQ and High on Both groups elicited significantly reduced N170 ERPs compared to the average groups. The High CEQ group demonstrated significantly reduced N170 ERPs compared to Average Non-Users. None of the high scoring groups significantly differed in N170 ERP response from each other. No interaction was detected between trial-type and group, although group differences in laterality were robust and consistent across trial types. Replicating past research, the CEQ and SPQ scales moderately correlated with each other. We propose that the detected attenuated N170 ERP demonstrated by the high scoring groups is a manifestation of an underlying shared cognitive vulnerability.
