Hydrologic behavior of a forested mountain slope in coastal British Columbia
Creators: name: Tischer, Evelyn
Publisher: name: University of British Columbia
Year: 2010

description: This is a study of the hydrologic behavior of a forested west coast mountain slope soil. Flow mechanisms were investigated using experimental results, mainly outflow hydrographs, and a simple model of saturated flow over a steep bed, described in the second chapter and called the kinematic wave model. The main experiments consisted of subjecting the forest plot to both concentrated and uniform irrigation. The rationale for using concentrated irrigation was that it was expected it would enhance flow in low resistance paths or as fingers in the unsaturated zone, also called short-circuiting. It was concluded that the soil-water system behaves as if short-circuiting were not enhanced by concentration of irrigation. The fact that both the observed hydrograph and the kinematic wave model hydrograph display a straight line rise was the rationale for using the kinematic wave model. It indicates that the system behaves as if the kinematic wave model were valid. Readily verified assumptions are a steep bed slope and a high hydraulic conductivity due to concentration of low resistance paths on top of the bed. As for other assumptions, it can only be said that the system behaves as if they were satisfied. In particular it behaves as if no short-circuiting occurred. Using the kinematic wave model, an effective hydraulic conductivity of 1.6 x 10⁻⁴ to 3.2 x 10⁻⁴ ms⁻¹ was obtained for the saturated zone. Finally, it was shown that nonlinear flow, if it occurs at all, is probably uncommon in the unsaturated zone of the Forest plot and its vicinity. It is not certain whether it can occur in the saturated zone of the Forest plot.

description: Transparent materials do not absorb light but have profound influence on the phase evolution of transmitted radiation. One consequence is chromatic dispersion, i.e., light of different frequencies travels at different velocities, causing ultrashort laser pulses to elongate in time while propagating. Here we experimentally demonstrate ultrathin nanostructured coatings that resolve this challenge: we tailor the dispersion of silicon nanopillar arrays such that they temporally reshape pulses upon transmission using slow light effects and act as ultrashort laser pulse compressors. The coatings induce anomalous group delay dispersion in the visible to near-infrared spectral region around 800 nm wavelength over an 80 nm bandwidth. We characterize the arrays' performance in the spectral domain via white light interferometry and directly demonstrate the temporal compression of femtosecond laser pulses. Applying these coatings to conventional optics renders them ultrashort pulse compatible and suitable for a wide range of applications.

description: The dynamics of a cascaded system that consists of two atom-cavity subsystems is studied by using the quantum trajectory method. Considering the two atom-cavity subsystems driven by a Raman interaction, analytical solutions are obtained. Subsequently, the entanglement evolution between the two atoms is studied, and it is shown that the entanglement can be stored by switching off the Raman coupling. By monitoring the radiation field, the entanglement between the two atoms can be enhanced.

description: Recently, an intriguing relationship (the "double copy") has been discovered between theories like electromagnetism, and gravity. This potentially gives us a new way to think about gravity, and there are also practical applications involving the efficient calculation of gravitational observables, and also how to simulate gravity using optical systems. In this tutorial, we will review what is known about the double copy, and argue that now is the perfect time for researchers in optics and / or condensed matter to become interested in this fascinating correspondence.

description: Path integral Monte Carlo approach is used to study the coupled quantum dynamics of the electron and nuclei in hydrogen molecule ion. The coupling effects are demonstrated by comparing differences in adiabatic Born--Oppenheimer and non-adiabatic simulations, and inspecting projections of the full three-body dynamics onto adiabatic Born--Oppenheimer approximation. Coupling of electron and nuclear quantum dynamics is clearly seen. Nuclear pair correlation function is found to broaden by 0.040 a_0 and average bond length is larger by 0.056 a_0. Also, non-adiabatic correction to the binding energy is found. Electronic distribution is affected less, and therefore, we could say that the adiabatic approximation is better for the electron than for the nuclei.

description: We consider FRW cosmology in non-local modified gravity. Its local scalar-tensor formulation is developed. It is explicitly demonstrated that such theory may lead to the unification of early-time inflation with late-time cosmic acceleration. The quintessence or phantom era may emerge for specific form of the action. The coupled non-local-F(R) gravity is also investigated. It is shown that such theory being consistent with Solar System tests may lead to the known universe history sequence: inflation, radiation/matter dominance and dark epoch.

description: The rotation profile of a magnetized plasma cylinder composed of multiple fluids is investigated analytically, expanding on previous results. The analytic steady-state solution is used as a benchmark for a time-dependent multiple-fluid finite-difference code, MITNS: Multiple-Ion Transport Numerical Solver. Magnetic field evolution is taken into account, both analytically and numerically. Its details are shown to be of importance when particles are allowed out of the domain. MITNS reproduces the asymptotic expansion results for a small parameter $δ\lll1$. For $\sqrt{m_e/m_i} \sim δ\ll 1$, a slightly different regime, dominated by viscosity-induced transport of ions, is found numerically and analytically. This validation supports the use of this code for more complex time-dependent calculations in the future.

Coping strategies for working women : aerobic exercise and relaxation interventions
Creators: name: Haney, Colleen Judith
Publisher: name: University of British Columbia
Year: 2010

description: This study examined the effects of two 8-week stress-management interventions (aerobic exercise and progressive relaxation) on reductions in trait anxiety, increases in self-efficacy, and enhancement of coping strategies for sedentary working women. It was expected that aerobic exercise, a relatively new treatment, would be as effective or more effective than progressive relaxation, a well researched treatment, as a stress-management intervention. The subjects were 72 females aged 24-59, (M = 39.8) solicited from the Vancouver community via newspaper advertisement asking for stressed volunteers to participate in two stress-management programs. They were interviewed and randomly assigned to an aerobic exercise or progressive relaxation treatment. The treatment sessions were conducted over an 8-week period with subjects meeting in groups for 1 1/2 hours per week. Prior to the first session subjects were administered: STAI-T (Spielberger, Gorsuch, & Lushene, 1970), the General Self-Efficacy Scale (Sherer et al., 1982), Ways of Coping Checklist (Lazarus 6 Folkman, 1984), and a 7-Day Exercise Recall Inventory (Blair, 1984). Subjects were assessed again at post treatment and at 8-week follow-up. Repeated measures, multivariate analysis of variance with preplanned contrasts, indicated that both treatment groups were effective in decreasing trait anxiety and increasing self-efficacy from pre- to post-treatment. These changes were maintained at 8-week follow-up. In addition, a one-way multivariate analysis of variance with repeated measures indicated that the total number of coping strategies, as well as the difference between the number of problem-focused and emotion-focused coping strategies, did not change significantly from pre- to post-treatment. Additionally, there was a negative relationship between low scores in self-efficacy and high scores in emotion-focused coping. In response to ancillary post-treatment and follow-up questionnaires, aerobic exercise was perceived by the participants as a more satisfactory stress-management treatment. Implications of these results and suggestions for future studies are discussed.

description: Today, cellular networks have saturated frequencies below 3\,GHz. Because of increasing capacity requirements, 5th generation (5G) mobile networks target the 3.5\,GHz band (3.4 to 3.8\,GHz). Despite its expected wide usage, there is little empirical path loss data and mobile radio network planning experience for the 3.5\,GHz band available. This paper presents the results of rural, suburban, and urban measurement campaigns using a pre-standard 5G prototype testbed operating at 3.5\,GHz, with outdoor as well as outdoor-to-indoor scenarios. Based on the measurement results, path loss models are evaluated, which are essential for network planning.

description: In this paper we numerically conduct micromagnetic modelling to optimize computational boundaries of magnetic thin-film elements applicable to single and double point contact spin torque nano-oscillators. Different boundary conditions have been introduced to compensate spin waves reflections at boundaries that are based on extended layers, absorbing boundaries, and focal point methods and are compared with a technique based on scattering theory. A surface roughness boundary model is presented which is modelled according to the Rayleigh criterion to minimize specular reflections at computational boundaries. It is shown that the surface roughness model disperses the reflected spin waves and improves the signal to background noise ratio. The model is tested in comparison to conventional approaches such as extended layer systems, variable damping constant and focal point methods for double point contacts. The surface roughness model gives solutions that are stable in time, in qualitative agreement with experiments and capable to reproduce phenomena such as phase locking in double point contacts.

description: The quantum field-theoretic approach to classical observables due to Kosower, Maybee and O'Connell provides a rigorous pathway from on-shell scattering amplitudes to classical perturbation theory. In this paper, we promote this formalism to describe general classical spinning objects by using coherent spin states. Our approach is fully covariant with respect to the massive little group ${\rm SU}(2)$ and is therefore completely synergistic with the massive spinor-helicity formalism. We apply this approach to classical two-body scattering due gravitational interaction. Starting from the coherent-spin elastic-scattering amplitude, we derive the classical impulse and spin kick observables to first post-Minkowskian order but to all orders in the angular momenta of the massive spinning objects. From the same amplitude, we also extract an effective two-body Hamiltonian, which can be used beyond the scattering setting. As a cross-check, we rederive the classical observables in the center-of-mass frame by integrating the Hamiltonian equations of motion to the leading order in Newton's constant.

We present a simple network model where the weights are generated dynamically and they shape the developing topology. By tuning a model parameter governing the importance of weights, the resulting networks undergo a gradual structural transition from a module free topology to one with communities. The model also reproduces many features of large social networks, including the "weak links" property.

description: Abstract

The objective of this study was to apply Quality by Design (QBD) concept for development and validation of stability indicating high-performance thin-layer chromatography (HPTLC) method for estimation of Favipiravir in bulk and marketed tablet formulations. Box-Behnken design was applied to optimize chromatographic conditions and to determine their effect on retardation factor (Rf) value. The developed chromatographic method was validated for linearity, specificity, range, accuracy, LOD and LOQ, precision and robustness as per ICH guidelines. This study was carried out by using the mobile phase containing toluene-ethyl acetate-methanol-formic acid in the ratio of (7:2:1:0.5 v/v). Scanning and densitometric analysis were done at 240 nm. The densitogram of favipiravir was obtained at Rf value of 0.49±0.02. The correlation coefficient was found to be 0.9913 in the concentration range of 2000-12000 ng/band. The percentage recovery was found to be between 98.37 – 100.20%. The LOD and LOQ were found be 20.50 ng/band and 62.13 ng/band respectively. For stability study, favipiravir was subjected to acid, base, oxidation, heat and photo-degradation studies. The developed method has advantages in being robust and able to determine the model drugs and degradation products with sensitivity, selectivity using simple mobile phase.

description: Recent water line observations toward several low-mass protostars suggest low water gas fractional abundances in the inner warm envelopes. Water destruction by X-rays has been proposed to influence the water abundances in these regions, but the detailed chemistry, including the nature of alternative oxygen carriers, is not yet understood. In this study, we aim to understand the impact of X-rays on the composition of low-mass protostellar envelopes, focusing specifically on water and related oxygen bearing species. We compute the chemical composition of two low-mass protostellar envelopes using a 1D gas-grain chemical reaction network, under various X-ray field strengths. According to our calculations, outside the water snowline, the water gas abundance increases with $L_{\mathrm{X}}$. Inside the water snowline, water maintains a high abundance of $\sim 10^{-4}$ for small $L_{\mathrm{X}}$, with water and CO being the dominant oxygen carriers. For large $L_{\mathrm{X}}$, the water gas abundances significantly decrease just inside the water snowline (down to $\sim10^{-8}-10^{-7}$) and in the innermost regions ($\sim10^{-6}$). For these cases, the O$_{2}$ and O gas abundances reach $\sim 10^{-4}$ within the water snowline, and they become the dominant oxygen carriers. The HCO$^{+}$ and CH$_{3}$OH abundances, which have been used as tracers of the water snowline, significantly increase/decrease within the water snowline, respectively, as the X-ray fluxes become larger. The abundances of some other dominant molecules, such as CO$_{2}$, OH, CH$_{4}$, HCN, and NH$_{3}$, are also affected by strong X-ray fields, especially within their own snowlines. These X-ray effects are larger in lower density envelope models. Future observations of water and related molecules (using e.g., ALMA and ngVLA) will access the regions around protostars where such X-ray induced chemistry is effective.

description: Quantum Fisher information and signal-to-noise ratio bounds are derived for the estimation of moments of general partially coherent objects. Under an asymptotic analysis in the sub-Rayleigh regime, these bounds are shown to be less restrictive than those of the incoherent case. This leaves open the possibility of more accurately estimating object distribution moments when the object is partially coherent.

description: The cavity method is a well established technique for solving classical spin models on sparse random graphs (mean-field models with finite connectivity). Laumann et al. [arXiv:0706.4391] proposed recently an extension of this method to quantum spin-1/2 models in a transverse field, using a discretized Suzuki-Trotter imaginary time formalism. Here we show how to take analytically the continuous imaginary time limit. Our main technical contribution is an explicit procedure to generate the spin trajectories in a path integral representation of the imaginary time dynamics. As a side result we also show how this procedure can be used in simple heat-bath like Monte Carlo simulations of generic quantum spin models. The replica symmetric continuous time quantum cavity method is formulated for a wide class of models, and applied as a simple example on the Bethe lattice ferromagnet in a transverse field. The results of the methods are confronted with various approximation schemes in this particular case. On this system we performed quantum Monte Carlo simulations that confirm the exactness of the cavity method in the thermodynamic limit.

description: Large clouds of cold atoms prepared in a magneto-optical trap are known to present spatiotemporal instabilities when the frequency of the trapping lasers is brought close to the atomic resonance. This system bears similarities with trapped plasmas where the role of the Coulomb interaction is played by the exchange of scattered photons, and astrophysical objects such as stars whose size is dependent on radiative forces. We present in this paper a study of the phase-space of such instabilities, and reveal different dynamical regimes. Three dimensional simulations of the highly nonlinear atomic dynamics permit a detailed analysis of the experimental observations.

description: We present spectroscopy of individual stars in 26 Magellanic Cloud (MC) star clusters with the aim of estimating dynamical masses and $V$-band mass-to-light ($M/L_V$) ratios over a wide range in age and metallicity. We obtained 3137 high-resolution stellar spectra with M2FS on the \textit{Magellan}/Clay Telescope. Combined with 239 published spectroscopic results of comparable quality, we produced a final sample of 2787 stars with good quality spectra for kinematic analysis in the target clusters. Line-of-sight velocities measured from these spectra and stellar positions within each cluster were used in a customized expectation-maximization (EM) technique to estimate cluster membership probabilities. Using appropriate cluster structural parameters and corresponding single-mass dynamical models, this technique ultimately provides self-consistent total mass and $M/L_V$ estimates for each cluster. Mean metallicities for the clusters were also obtained and tied to a scale based on calcium IR triplet metallicites. We present trends of the cluster $M/L_V$ values with cluster age, mass and metallicity, and find that our results run about 40 per cent on average lower than the predictions of a set of simple stellar population (SSP) models. Modified SSP models that account for internal and external dynamical effects greatly improve agreement with our results, as can models that adopt a strongly bottom-light IMF. To the extent that dynamical evolution must occur, a modified IMF is not required to match data and models. In contrast, a bottom-heavy IMF is ruled out for our cluster sample as this would lead to higher predicted $M/L_V$ values, significantly increasing the discrepancy with our observations.

description: Keeping single-qubit quantum coherence above some threshold value not far below unity is a prerequisite for fault-tolerant quantum error correction (QEC). We study the initial dephasing of solid-state qubits in the independent-boson model, which describes well recent experiments on quantum dot (QD) excitons both in bulk and in substrates of reduced geometry such as nanotubes. Using explicit expressions for the exact coherence dynamics, a minimal QEC rate is identified in terms of the error threshold, temperature, and qubit-environment coupling strength. This allows us to systematically study the benefit of a current trend towards substrates with reduced dimensions.

description: We present systematic results, based on density functional calculations, for the structure and energetics of $^3$He and $^4$He nanodroplets doped with alkaline earth atoms. We predict that alkaline earth atoms from Mg to Ba go to the center of $^3$He drops, whereas Ca, Sr, and Ba reside in a deep dimple at the surface of $^4$He drops, and Mg is at their center. For Ca and Sr, the structure of the dimples is shown to be very sensitive to the He-alkaline earth pair potentials used in the calculations. The $5s5p\leftarrow5s^2$ transition of strontium atoms attached to helium nanodroplets of either isotope has been probed in absorption experiments. The spectra show that strontium is solvated inside $^3$He nanodroplets, supporting the calculations. In the light of our findings, we emphasize the relevance of the heavier alkaline earth atoms for analyzing mixed $^3$He-$^4$He nanodroplets, and in particular, we suggest their use to experimentally probe the $^3$He-$^4$He interface.

description: Let $(C,\underline{w})$ be a polarized nodal reducible curve. In this paper we consider coherent systems of type $(r,d,k)$ on $C$ with $k < r$. We prove that the moduli spaces of $(\underline{w},α)$-stable coherent systems stabilize for large $α$ and we generalize several results known for the irreducible case when we chose a good polarization. Then, we study in details the components of moduli spaces containing coherent systems arising from locally free sheaves.

description: In a wide range of applications, the estimate of droplet evaporation time is based on the classical d2-law, which, assuming a fast mixing and fixed environmental properties, states that the droplet surface decreases linearly with time at a determined rate. However, in many cases the predicted evaporation rate is overestimated. In this Letter, we propose a revision of the d2-law capable to accurately determine droplet evaporation rate in dilute conditions by a proper estimate of the asymptotic droplet properties. Besides a discussion of the main assumptions, we tested the proposed model against data from direct numerical simulations finding an excellent agreement for predicted droplet evaporation time in dilute turbulent jet-sprays.

description: We live in the Information Age, and information has become a critically important component of our life. The success of the Internet made huge amounts of it easily available and accessible to everyone. To keep the flow of this information manageable, means for its faultless circulation and effective handling have become urgently required. Considerable research efforts are dedicated today to address this necessity, but they are seriously hampered by the lack of a common agreement about "What is information?" In particular, what is "visual information" - human's primary input from the surrounding world. The problem is further aggravated by a long-lasting stance borrowed from the biological vision research that assumes human-like information processing as an enigmatic mix of perceptual and cognitive vision faculties. I am trying to find a remedy for this bizarre situation. Relying on a new definition of "information", which can be derived from Kolmogorov's compexity theory and Chaitin's notion of algorithmic information, I propose a unifying framework for visual information processing, which explicitly accounts for the perceptual and cognitive image processing peculiarities. I believe that this framework will be useful to overcome the difficulties that are impeding our attempts to develop the right model of human-like intelligent image processing.

The effect of breath-holding during intense intermittent exercise on arterial blood gases, acid-base balance, and lactate
Creators: name: Matheson, Gordon Omar
Publisher: name: University of British Columbia
Year: 2010

description: Eight healthy female volunteers (mean age 24.4 ± 3.4) served as subjects in an experiment measuring acid-base and lactate changes while breath-holding during intense, intermittent exercise. The subjects were endurance trained (VO₂[sub max] = 56.8 ± 3.9 ml'kg-min⁻¹) with normal resting pulmonary function. Utilizing a counterbalance design, each subject repeated 5 intervals of a 15 second treadmill run at 125 % VO₂[sub max], once while breath-holding (BH), and once while breathing freely (NBH). Blood samples at rest, at the end of each work and rest interval, and throughout recovery were taken from a teflon catheter inserted in the radial artery. Samples were analyzed for pH, PaO₂, PaCO₂, SO₂, bicarbonate, and lactate. The results were analyzed using repeated measures ANOVA to compare BH with NBH. Significant (p≤.01), reductions were found in pH associated with significant elevations in PaCO₂ and HCO₃- at the end of each 15 sec exercise interval in the BH condition. These changes did not persist throughout the rest intervals (p>.05). In addition, significant (p≤.01), drops in PaO₂ and SaO₂ were found at the end of each exercise interval in the BH condition that were not found at the end of each rest interval. Significantly increased rates of lactate appearance in the arterial blood were found during recovery in the BH conditon. It was concluded that breath-holding during intense, intermittent exercise produced acid-base changes greater than those seen at similar exercise intensities while breathing. In addition, breath-holding during intense, intermittent exercise produces significant hypoxia. The significantly increased rates of lactate appearance during recovery in the BH condition are most likely due to increased tissue anaerobiosis.

description: We consider four-dimensional de Sitter, flat and anti de Sitter branes embedded in a six-dimensional bulk spacetime whose dynamics is dictated by Lovelock theory. We find, applying a generalised version of Birkhoff's theorem, that all possible maximally symmetric braneworld solutions are embedded in Wick-rotated black hole spacetimes of Lovelock theory. These are warped solitonic spaces, where the horizons of the black hole geometries correspond to the possible positions of codimension-2 branes. The horizon temperature is related via conical singularities to the tension or vacuum energy of the branes. We classify the braneworld solutions for certain combinations of bulk parameters, according to their induced curvature, their vacuum energy and their effective compactness in the extra dimensions. The bulk Lovelock theory gives an induced gravity term on the brane, which, we argue, generates four-dimensional gravity up to some distance scale. As a result, some simple solutions, such as the Lovelock corrected Schwarzschild black hole in six dimensions, are shown to give rise to self-accelerating braneworlds. We also find that several other solutions have self-tuning properties. Finally, we present regular gravitational instantons of Lovelock gravity and comment on their significance.
