description: We have fabricated a quantum dot single electron transistor based on an AlGaAs/GaAs heterostructure without any modulation doping. Our device is very stable from an electronic perspective, with clear Coulomb blockade oscillations, and minimal drift in conductance when the device is set to the midpoint of a Coulomb blockade peak and held at constant gate bias. Bias spectroscopy measurements show typical Coulomb 'diamonds' free of any significant charge fluctuation noise. We also observe excited state transport in our device.

description: Earlier measurements of the masses and radii of the detached eclipsing binary V20 in the open cluster NGC 6791 were accurate enough to demonstrate that there are significant differences between current stellar models. Here we improve on those results and add measurements of two additional detached eclipsing binaries, the cluster members V18 and V80. The enlarged sample sets much tighter constraints on the properties of stellar models than has hitherto been possible, thereby improving both the accuracy and precision of the cluster age. We employed (i) high-resolution UVES spectroscopy of V18, V20 and V80 to determine their spectroscopic effective temperatures, [Fe/H] values, and spectroscopic orbital elements, and (ii) time-series photometry from the Nordic Optical Telescope to obtain the photometric elements. The masses and radii of the V18 and V20 components are found to high accuracy, with errors on the masses in the range 0.27-0.36% and errors on the radii in the range 0.61-0.92%. V80 is found to be magnetically active, and more observations are needed to determine its parameters accurately. The metallicity of NGC 6791 is measured from disentangled spectra of the binaries and a few single stars to be [Fe/H]= +0.29 \pm 0.03 (random) \pm 0.07 (systematic). The cluster reddening and apparent distance modulus are found to be E(B - V) = 0.160 \pm 0.025 and (m - M)V = 13.51 \pm 0.06 . A first model comparison shows that we can constrain the helium content of the NGC 6791 stars, and thus reach a more accurate age than previously possible. It may be possible to constrain additional parameters, in particular the C, N, and O abundances. This will be investigated in paper II.

Machine learning applications to geophysical data analysis
Creators: name: Bougher, Benjamin Bryan
Publisher: name: University of British Columbia
Year: 2016

description: The sedimentary layers of the Earth are a complex amorphous material formed from chaotic, turbulent, and random natural processes. Exploration geophysicists use a combination of assumptions, approximate physical models, and trained pattern recognition to extract useful information from complex remote sensing data such as seismic and well logs. In this thesis I investigate supervised and unsupervised machine learning models in geophysical data analysis and present two novel applications to exploration geophysics. Firstly, interpreted well logs from the Trenton-Black River study are used to train a classifier that results in a success rate of 67% at predicting stratigraphic units from gamma ray logs. I use the scattering transform, a multiscale analysis transform, to extract discriminating features to feed a K-nearest neighbour classifier. A second experiment frames a conventional pre-stack seismic data characterization workflow as an unsupervised machine learning problem that is free from physical assumptions. Conventionally, the Shuey model is used to fit the angle dependent reflectivity response of seismic data. I instead use principle component based approaches to learn projections from the data that improve classification. Results on the Marmousi II elastic model and an industry field dataset show that unsupervised learning models can be effective at segmenting hydrocarbon reservoirs from seismic data.

description: The development of new electronic markets is challenging, since many factors influence the market outcomes and hence the markets’ success. Even worse, a fundamental lesson learned from economics is that details matter: small changes in market design can have a significant impact on the market participant’s behaviors and thus on the achieved outcomes. Consequently a well structured process for design, implementation, testing and maintenance of markets is required. meet2trade is a software tool suite designed to systematically support each step of such a Market Engineering (ME) process. This paper presents the generic trading platform meet2trade that enables users to individually configure their own electronic markets, to run them on the integrated auction server, and to evaluate them using the built-in full-featured lab experiment system.

description: This article explores the possibilities of technology for working universal bite structure gear shafts to improve the process of biting dry fruits. The authors conducted experiments based on the size of each of the dry fruits to determine their optimal parameters, such as the diameter of the toothed shafts, the radius of the ribs and the main working material. The effect of the physical and mechanical properties of dry fruit on the efficiency of processing was also studied. Obtained result showed that bites of dry fruits universal structure help to increase the quality of the product and reduce damage to the kernels. The process of dry fruit bites can be improved by using the technology of universal bite structure gear shafts, which is an effective equipment.

description: Let $G$ be a finite $p$-group of order $p^n$. YA. G. Berkovich (Journal of Algebra {\bf 144}, 269-272 (1991)) proved that $G$ is elementary abelian $p$-group if and only if the order of its Schur multiplier, $M(G)$, is at the maximum case. In this paper, first we find the upper bound $p^{χ_{c+1}{(n)}}$ for the order the $c$-nilpotent multiplier of $G$, $M^{(c)}(G)$, where $χ_{c+1}{(i)}$ is the number of basic commutators of weight $c+1$ on $i$ letters. Second, we obtain the structure of $G$, in abelian case, where $|M^{(c)}(G)|=p^{χ_{c+1}{(n-t)}}$, for all $0\leq t\leq n-1$. Finally, by putting a condition on the kernel of the left natural map of the generalized Stallings-Stammbach five term exact sequence, we show that an arbitrary finite $p$-group with the $c$-nilpotent multiplier of maximum order is an elementary abelian $p$-group.

description: Shrinking meat intake levels and simultaneously increasing consumption of plant-based products among consumers suggest that consumers’ dietary behavior implies the purchase of plant-based food substitutes. We contribute to the literature by investigating the most important determinants of consumers’ dietary behavior and attitude towards plant-based food substitutes and whether consumers’ dietary behavior is of relevance for the attitude towards plant-based food substitutes. Data of 1,363 consumers was used for structural equation modeling as well as necessary condition analysis. Consumers’ dietary behavior is found to play only a minor role in attitude formation towards plant-based food substitutes. Dietary behavior is primarily influenced by animal welfare concerns. We did not find environmental concerns, consumers’ perceived effectiveness, and health consciousness to influence dietary behavior. However, as consumers associate a high standard of animal welfare with healthiness and food safety, following a plant-based diet due to animal welfare concerns might be an altruistic pretext for health consciousness as an egoistic motive.

description: We report the first observational search for tau neutrinos from gamma ray bursts (GRBs) using one of the Ashra light collectors. The earth-skimming tau-neutrino technique of imaging Cherenkov tau showers was applied as a detection method. We set stringent upper limits on the tau-neutrino fluence in PeV-EeV region for 3780 s (between 2.83 and 1.78 hours before) and another 3780 s (between 21.2 and 22.2 hours after) surrounding GRB081203A triggered by the Swift satellite. This first search for PeV-EeV tau neutrino complements other experiments in energy range and methodology, and suggests the prologue of "multi-particle astronomy" with a precise determination of time and location.

description: The conjugation site of dihydrofluorescein (H2F) is important for the rational design of H2F-based reactive oxygen species (ROS) sensors. Despite the prevalence of H2F analogs detecting cellular ROS, the role of the carboxylic acid of H2F in oxidation is still unclear. To get insight into the conjugation site of H2F, we synthesized H2F diacetate (2) and its amide derivative (3). The absorption and emission spectra of deacetylated 2 and 3 in the presence of H2O2/hematin showed that the carboxylic acid of H2F plays a crucial role in the oxidation of H2F. NMR and HPLC analysis of the oxidation product of deacetylated 3 showed a quantitative and fast generation of non-fluorescent spirolactam (F-Lactam). As regards these observations, we untouched the carboxylic acid at the 3rd position and designed an H2F-based ROS sensor (7) that conjugated the lipophilic chain at the 5th position instead. A series of confocal microscopic experiments of 7 demonstrated that 7 prefers the ER location and that ROS are elevated in the cells by ER stress inducers.

Equivalent energy based design procedure for controlled rocking-concentrically braced frames
Creators: name: Boddapati, Vinay Kumar
Publisher: name: University of British Columbia
Year: 2016

description: Conventional seismic force resisting systems (SFRSs) such as moment frames, braced frames and shear wall systems rely on the use of ductile design philosophy, where structural components are designed to undergo large inelastic deformations to dissipate the sudden surge of the earthquake energy. This design philosophy has shown to be very effective in preventing structural collapse. However, the extensive inelastic deformation usually leads to significant damage to the structural and non-structural components. Many earthquake reconnaissance reports show that this design philosophy typically leads to residual deformations which result in hefty financial losses. In recent years, novel structural systems, which are targeted to achieve higher performance, have been developed. These structural systems are targeted to resist strong earthquake shaking with minimal structural/non-structural damages. This allows the structure to remain functional immediately after the earthquake. Controlled rocking-concentrically braced frame (CR-CBF) is one such novel system developed to achieve higher performance. CR-CBF relies on the use of post-tensioning (PT) tendons and supplemental damping devices (ED), to create a controlled-rocking mechanism at the base of the structure. Since gravity loads alone cannot eliminate the residual deformations, the PT are introduced in the system to allow self-centering. In addition, ED are installed in the system to dissipate the sudden surge of seismic energy and control the peak displacement response of the structure. Both the PT and ED components are designed to be easily replaceable without affecting the functionality of the structure after a strong earthquake shaking. A novel seismic design methodology named Equivalent-Energy Design Procedure (EEDP) is adopted in this study to design the CR-CBF. This design procedure allows the designers to select different performance objectives at different shaking intensities. Two prototype buildings with varying heights are designed using EEDP. Detailed numerical models of these prototypes are developed in OpenSees (2010) to evaluate the seismic performance of CR-CBF. Detailed performance assessment of the CR-CBFs, in terms of adjusted collapse margin ratio, are evaluated using the FEMA P695 (2009) methodology. The results presented in this thesis demonstrate that the proposed CR-CBFs have adequate earthquake safety and they can be designed efficiently using the proposed EEDP approach.

description: Zn(CN)2 and Ni(CN)2 are known for exhibiting anomalous thermal expansion over a wide temperature range. The volume thermal expansion coefficient for the cubic, three dimensionally connected material, Zn(CN)2, is negative (αV = -51 x 10-6 K-1) while for Ni(CN)2, a tetragonal material, the thermal expansion coefficient is negative in the two dimensionally connected sheets (αa=-7 x 10-6 K-1), but the overall thermal expansion coefficient is positive (αV=48 x 10-6 K-1). We have measured the temperature dependence of phonon spectra in these compounds and analyzed them using ab-initio calculations. The spectra of the two compounds show large differences that cannot be explained by simple mass renormalization of the modes involving Zn (65.38 amu) and Ni (58.69 amu) atoms. This reflects the fact that the structure and bonding are quite different in the two compounds. The calculated pressure dependence of the phonon modes and of the thermal expansion coefficient, αV, are used to understand the anomalous behavior in these compounds. Our ab-initio calculations indicate that it is the low-energy rotational modes in Zn(CN)2, which are shifted to higher energies in Ni(CN)2, that are responsible for the large negative thermal expansion. The measured temperature dependence of the phonon spectra has been used to estimate the total anharmonicity of both compounds. For Zn(CN)2, the temperature- dependent measurements (total anharmonicity), along with our previously reported pressure dependence of the phonon spectra (quasiharmonic), is used to separate the explicit temperature effect at constant volume (intrinsic anharmonicity).

description: Cellular and organismal redox imbalance leading to the accumulation of reactive oxygen species significantly enhances lipid peroxidation (LPO). LPO is relatively well studied for phospholipid membranes and to some extent for circulating lipoproteins. However, it is rarely addressed for intracellular lipid droplets (LDs). Here we optimized an in vitro model system to investigate oxidizability of different lipid classes within artificial LDs (aLDs). To this end, aLDs were reconstructed using differential centrifugation and characterized by a variety of analytical methods. Influence of different lipid compositions on aLDs size was studied and showed opposing effects of unsaturated phospholipids (PLs), triacyclglycerols (TAGs) and cholesteryl esters (CEs). To address aLDs oxidizability, the LPO sensitive ratiometric probe BODIPY-C11 was infused into aLDs, and lipid peroxidation kinetics, upon LPO activation either by copper/ascorbate or 2,2′-azobis(2-methylpropionamidine), was followed up by fluorescence spectroscopy. Generated lipid peroxidation products were additionally identified and relatively quantified by high-resolution LC-MS/MS. It was demonstrated that lipid composition is detrimental to aLD’s oxidation sensitivity. Increasing unsaturation levels in the PL monolayer or the TAG core increases oxidation sensitivity, whereas the presence of CEs in the LD core has a dual effect depending on the acylated fatty acid. Moreover, not only the total level of lipid unsaturation, but also the ratio between different lipid species was shown to play a significant role in LPO propagation. This shows that the lipid composition of aLD’s determines their sensitivity to LPO. As LDs lipidome reflects and is dynamically influenced by cellular and organismal metabolic status, our findings provide an important observation linking LD lipid composition and their redox sensitivity.

As compared to previous studies, we use an extensive sample of observations that include all the radio/X-ray spectral states that have been categorized in the source recently. In this study we identify two additional instances of Quasi-Periodic Oscillations that have centroid frequencies in the mHz regime. These events are all associated to a certain extent with major radio flaring, that in turn is associated with relativistic jet ejection events. We review briefly scenarios whereby the Quasi-Periodic Oscillations may arise.

description: The radio surface brightness-to-diameter (Σ - D) relation for supernova remnants (SNRs) in the starburst galaxy M82 is analyzed in a statistically more robust manner than in the previous studies that mainly discussed sample quality and related selection effects. The statistics of data fits in log Σ - log D plane are analyzed by using vertical (standard) and orthogonal regressions. As the parameter values of D - Σ and Σ - D fits are invariant within the estimated uncertainties for orthogonal regressions, slopes of the empirical Σ - D relations should be determined by using the orthogonal regression fitting procedure. Thus obtained Σ - D relations for samples which are not under severe influence of the selection effects could be used for estimating SNR distances. Using the orthogonal regression fitting procedure Σ - D slope β \approx 3.9 is obtained for the sample of 31 SNRs in M82. The results of implemented Monte Carlo simulations show that the sensitivity selection effect does not significantly influence the slope of M82 relation. This relation could be used for estimation of distances to SNRs that evolve in denser interstellar environment, with number denisty up to 1000 particles per cm3 .

description: Generalized Langevin equations (GLE) with multiplicative white Poisson noise pose the usual prescription dilemma leading to different evolution equations (master equations) for the probability distribution. Contrary to the case of multiplicative gaussian white noise, the Stratonovich prescription does not correspond to the well known mid-point (or any other intermediate) prescription. By introducing an inertial term in the GLE we show that the Ito and Stratonovich prescriptions naturally arise depending on two time scales, the one induced by the inertial term and the other determined by the jump event. We also show that when the multiplicative noise is linear in the random variable one prescription can be made equivalent to the other by a suitable transformation in the jump probability distribution. We apply these results to a recently proposed stochastic model describing the dynamics of primary soil salinization, in which the salt mass balance within the soil root zone requires the analysis of different prescriptions arising from the resulting stochastic differential equation forced by multiplicative white Poisson noise whose features are tailored to the characters of the daily precipitation. A method is finally suggested to infer the most appropriate prescription from the data.

Visual influences on speech perception in infancy
Creators: name: Danielson, Donald Kyle
Publisher: name: University of British Columbia
Year: 2016

description: The perception of speech involves the integration of both heard and seen signals. Increasing evidence indicates that even young infants are sensitive to the correspondence between these sensory signals, and adding visual information to the auditory speech signal can change infants’ perception. Nonetheless, important questions remain regarding the nature of and limits to early audiovisual speech perception. In the first set of experiments in this thesis, I use a novel eyetracking method to investigate whether English-learning six-, nine-, and 11-month-olds detect content correspondence in auditory and visual information when perceiving non-native speech. Six- and nine-month-olds, prior to and in the midst of perceptual attunement, switch their face-scanning patterns in response to incongruent speech, evidence that infants at these ages detect audiovisual incongruence even in non-native speech. I then probe whether this familiarization, to congruent or incongruent speech, affects infants’ perception such that auditory-only phonetic discrimination of the non-native sounds is changed. I find that familiarization to incongruent speech changes—but does not entirely disrupt—six-month-olds’ auditory discrimination. Nine- and 11-month-olds, in the midst and at the end of perceptual attunement, do not discriminate the non-native sounds regardless of familiarization condition. In the second set of experiments, I test how temporal information and phonetic content information may both contribute to an infant’s use of auditory and visual information in the perception of speech. I familiarize six-month-olds to audiovisual Hindi speech sounds in which the auditory and visual signals of the speech are incongruent in content and, in two conditions, are also temporally asynchronous. I hypothesize that, when presented with temporally synchronous, incongruent stimuli, infants rely on either the auditory or the visual information in the signal and use that information to categorize the speech event. Further, I predict that the addition of a temporal offset to this incongruent speech changes infants’ use of the auditory and visual information. Although the main results of this latter study are inconclusive, post-hoc analyses suggest that when visual information is presented first or synchronously with auditory information, as is the case in the environment, infants exhibit a moderate matching preference for auditory information at test.

Local softness, softness dipole and polarizabilities of functional groups: application to the side chains of the twenty amino acids

description: The values of molecular polarizabilities and softnesses of the twenty amino acids were computed ab initio (MP2). By using the iterative Hirshfeld scheme to partition the molecular electronic properties, we demonstrate that the values of the softness of the side chain of the twenty amino acid are clustered in groups reflecting their biochemical classification, namely: aliphatic, basic, acidic, sulfur containing, and aromatic amino acids . The present findings are in agreement with previous results using different approximations and partitioning schemes [P. Senet and F. Aparicio, J. Chem. Phys. 126,145105 (2007)]. In addition, we show that the polarizability of the side chain of an amino acid depends mainly on its number of electrons (reflecting its size) and consequently cannot be used to cluster the amino acids in different biochemical groups, in contrast to the local softness. Our results also demonstrate that the global softness is not simply proportional to the global polarizability in disagreement with the intuition that "a softer moiety is also more polarizable". Amino acids with the same softness may have a polarizability differing by a factor as large as 1.7. This discrepancy can be understood from first principles as we show that the molecular polarizability depends on a "softness dipole vector" and not simply on the global softness.

description: Based on data for 102 OB3 stars with known proper motions and radial velocities, we have tested the distances derived by Megier et al. from interstellar Ca II spectral lines. The internal reconciliation of the distance scales using the first derivative of the angular velocity of Galactic rotation Ω'0 and the external reconciliation with Humphreys's distance scale for OB associations refined by Mel'nik and Dambis show that the initial distances should be reduced by \approx 20%. Given this correction, the heliocentric distances of these stars lie within the range 0.6-2.6 kpc. A kinematic analysis of these stars at a fixed Galactocentric distance of the Sun, R0=8 kpc, has allowed the following parameters to be determined:(1) the solar peculiar velocity components (U_o,V_o,W_o)=(8.9,10.3,6.8)\pm(0.6,1.0,0.4) km/s;(2) the Galactic rotation parameters Ω_o=-31.5\pm0.9 km/s/kpc, Ω'_o=+4.49\pm0.12 km/s/kpc^2, Ω"_o=-1.05\pm0.38 km/s/kpc^3, (the corresponding Oort constants are A=17.9\pm0.5 km/s/kpc, B=-13.6\pm1.0 km/s/kpc and the circular rotation velocity of the solar neighborhood is |V_o|=252\pm14 km/s); (3) the spiral density wave parameters, namely: the perturbation amplitudes for the radial and azimuthal velocity components, respectively, f_R = -12.5\pm1.1 km/s and f_θ=2.0\pm1.6 km/s; the pitch angle for the two-armed spiral pattern i=-5.3\pm0.3 degrees, with the wavelength of the spiral density wave at the solar distance being λ=2.3\pm0.2 kpc; the Sun's phase in the spiral wave χ_o=-91\pm4 degrees.

description: We report a spectral-line survey of the extreme carbon star IRC+10216 carried out between 293.9 and 354.8 GHz with the Submillimeter Array. A total of 442 lines were detected, more than 200 for the first time; 149 are unassigned. Maps at an angular resolution of ~3" were obtained for each line. A substantial new population of narrow lines with an expansion velocity of ~4 km/s (i.e. ~ 30% of the terminal velocity) was detected. Most of these are attributed to rotational transitions within vibrationally excited states, emitted from energy levels above the v=0, J=0 ground state with excitation energy of 1000-3000 K. Emission from these lines appears to be centered on the star with an angular extent of <1". We use multiple transitions detected in several molecules to derive physical conditions in this inner envelope of IRC+10216.

description: The Lax pair formulation of the two-component Camassa-Holm equation (CH2) is generalized to produce an integrable multi-component family, CH(n,k), of equations with $n$ components and $1\le |k|\le n$ velocities. All of the members of the CH(n,k) family show fluid-dynamics properties with coherent solitons following particle characteristics. We determine their Lie-Poisson Hamiltonian structures and give numerical examples of their soliton solution behaviour. We concentrate on the CH(2,k) family with one or two velocities, including the CH(2,-1) equation in the Dym position of the CH2 hierarchy. A brief discussion of the CH(3,1) system reveals the underlying graded Lie-algebraic structure of the Hamiltonian formulation for CH(n,k) when $n\ge3$.

description: Bachet elliptic curves are the curves y^2=x^3+a^3 and in this work the group structure E(F_{p}) of these curves over finite fields F_{p} is considered. It is shown that there are two possible structures E(F_{p}){\cong}C_{p+1} or E(F_{p}){\cong}C_{n}{\times}C_{nm}, for m,n{\in}{\mathbb{N}}, according to p{\equiv}5 (mod6) and p{\equiv}1 (mod6), respectively. A result of Washington is restated in a more specific way saying that if E(F_{p}){\cong}Z_{n}{\times}Z_{n}, then p{\equiv}7 (mod12) and p=n^2{\mp}n+1.

description: The HPLWR is an innovative reactor concept cooled with water at supercritical pressure. The pronounced changes of water properties with the heat-up demands advanced analyses tools which have been developed and successfully applied.

description: Let (M,g) be a smooth connected compact Riemannian manifold of finite dimension n \geq 2 with a smooth boundary \partial M. We consider the problem -ε^2Δ_gu+u=|u|^{p-2}u, u>0 on M, \partial u/ \partialν=0 on \partial M where ν is an exterior normal to \partial M. The number of solutions of this problem depends on the topological properties of the manifold. In particular we consider the Lusternik Schnirelmann category of the boundary.

description: "Convergenza" e "conversazione" sono due termini affini nel loro significato etimologico: se "convergere" (cum + vergere) delinea un "andare gradualmente a terminare a un medesimo punto", "conversare" (cum + versare, frequentativo di vertere) nel suo "volgere insieme" gli è decisamente prossimo. Non stupisce, dunque, che proprio la cifra della conversazione possa ben sintetizzare l'intendimento critico del saggio di Remo Ceserani intitolato, appunto, Convergenze.

description: In disordered, viscoelastic or viscoplastic materials a sample response exhibits a recovery phenomenon after the removal of a constant load or after creep. We study experimentally the recovery in paper, a quasi two-dimensional system with intrinsic structural disorder. The deformation is measured by using the digital image correlation (DIC) method. By the DIC we obtain accurate displacement data and the spatial fields of deformation and recovered strains. The averaged results are first compared to several heuristic models for in particular viscoelastic polymer materials. The most important experimental quantity is the permanent creep strain, and we analyze whether it is non-zero by fitting the empirical models of viscoelasticity. We then present in more detail the spatial recovery behavior results from DIC, and show that they indicate a power-law -type relaxation. We outline results on sample-to-sample variation and collective, spatial fluctuations in the recovery behaviour. An interpretation is provided of the relaxation in the general context of glassy, interacting systems with barriers.

description: We present a new family of estimators of the Weibull tail-coefficient. The Weibull tail-coefficient is defined as the regular variation coefficient of the inverse failure rate function. Our estimators are based on a linear combination of log-spacings of the upper order statistics. Their asymptotic normality is established and illustrated for two particular cases of estimators in this family. Their finite sample performances are presented on a simulation study.
