description: NdFeAsO0.88F0.12 belongs to the recently discovered family of high-TC iron-based superconductors. The influence of high pressure on transport properties of this material has been studied. Contrary to La-based compounds, we did not observe a maximum in TC under pressure. Under compression, TC drops rapidly as a linear function of pressure with the slope k = -2.8 \pm 0.1 K / GPa. The extrapolated value of TC at zero pressure is about TC (0) = 51.7 \pm 0.4 K. At pressures higher than ~18.4 GPa, the superconducting state disappears at all measured temperatures. The resistance changes slope and shows a turn-up behavior, which may be related to the Kondo effect or a weak localization of two-dimensional carriers below ~45 K that is above TC and thus competing with the superconducting phase. The behavior of the sample is completely reversible at the decompression. On the bases of our experimental data, we propose a tentative P-T phase diagram of NdFeAsO0.88F0.12.

description: Extracorporeal Shock Wave Therapy (ESWT) is a noninvasive treatment for a variety of musculoskeletal ailments. A shock wave is generated in water and then focused using an acoustic lens or reflector so the energy of the wave is concentrated in a small treatment region where mechanical stimulation enhances healing. In this work we have computationally investigated shock wave propagation in ESWT by solving a Lagrangian form of the isentropic Euler equations in the fluid and linear elasticity in the bone using high-resolution finite volume methods. We solve a full three-dimensional system of equations and use adaptive mesh refinement to concentrate grid cells near the propagating shock. We can model complex bone geometries, the reflection and mode conversion at interfaces, and the the propagation of the resulting shear stresses generated within the bone. We discuss the validity of our simplified model and present results validating this approach.

description: Quantum information processing promises to have transformative impacts on information and communication science and technology. Photonic implementation of quantum information processing is among successful candidates for implementation of quantum computation and is an essential part of quantum communication. Linear optical quantum computation, specifically the KLM scheme, and quantum repeaters are prominent candidates for practical photonic quantum computation and long-distance quantum communication. Quantum memories for photons are key elements for any practical implementation of these schemes. Practical quantum memories require theoretical and experimental investigations into quantum memory protocols and physical systems for implementations. The present thesis is focused on studying new approaches toward practical solid-state based quantum memories. First, I present a proposal for a new quantum memory protocol called the controllable-dipole quantum memory. It represents a protocol, in a two-level system, without any optical control that is shown to be equivalent to the Raman type-quantum memory. Then I include our studies on the quantum memory based on the refractive index modulation of the host medium. It is shown that it can resemble the gradient echo quantum memory without a spatial gradient in the external field. These two protocols can be implemented in rare-earth doped crystals. With regards to using new physical systems, I present a proposal based on nitrogen vacancy centers. This may pave the way toward micron-scale on-chip quantum memories that may contribute to the implementation of integrated quantum photonics. Finally, I studied the precision requirements for the spin echo technique. This technique is necessary to extend the storage time in solid-state quantum memories, in which the coherence times are limited by spin inhomogeneous broadening.

description: The key objective of this study was to design, develop, and test a schema-less graph network Land Tenure Information System (LTIS) database prototype that is integrated with data mining and social network analysis techniques for the purpose of revealing hidden tenure information in the data related to conflict and post-conflict situations. Conventional LTISs are ineffective in conflict and post-conflict situations because they only describe recorded tenure information, and therefore these systems are not reflective of land practices taking place on the ground. In conflict and post-conflict situations, multiple sets of state held and privately held land tenure records may exist. The question then is how can LTISs be better designed to capture and describe tenure information in conflict and post-conflict situations. The study adapts a spiral software development model to develop a Talking Titler Network (TTN) database prototype. Simulated tenure data from two illustrative cases was entered and automatically mined and analysed within the database system. The results show that a schema-less graph network database integrated with data mining and social network analysis techniques can capture and describe complex land tenure information among and between people and tenure objects. In addition, the integrated techniques automatically extract, investigate, and visualise embedded tenure information emerging from these situations. The experimental test results provide important empirical observations to advance the TTN database design and development in order to assist in supporting land tenure dispute resolution for conflict and post-conflict situations. However, further field work needs to be carried out to validate the results.
Patterns of planetary boundary layer influence at the Whistler Mountain air chemistry observatory : an observational mountain meteorology study
Creators: name: Gallagher, John Patrick
Publisher: name: University of British Columbia
Year: 2010

description: An observational study was conducted to characterize atmospheric conditions at an air chemistry monitoring site on the summit of Whistler Mountain, British Columbia, Canada. Discrimination of air samples from the observatory as either representative of the free troposphere (FT) or modified by air from the valley-based planetary boundary layer (PBL) is critical to the proper interpretation of air chemistry datasets. Atmospheric data from a one-year study period were used to evaluate indicators and possible driving forces of PBL influence at the Whistler site. Diurnal cycles in water vapour and aerosol concentration were attributed primarily to convective uplift of PBL air during daytime heating hours. Analysis of these variables found that PBL influence was common in the spring and summer months and relatively rare in late fall through early winter. For the one-year period, 37% of the days had diurnal cycles in aerosol concentration that were considered typical of thermally induced vertical transport processes. Patterns of slope and valley winds were also identified for Whistler, and the presence of these diurnal wind systems was associated with enhanced aerosol concentration at the summit. Synoptic classification methods were used to describe the prevailing conditions on days with well-defined indicators of PBL influence. Strong solar insolation and light synoptic scale winds were found to be common on such days. Case studies of particular days confirmed that a deep convective boundary layer (CBL) of well-mixed air can encompass the mountain summits, even during the winter season. During the summer, a tendency for PBL constituents to remain aloft through the night means that the summit observatory can be unrepresentative of the FT for several days at a time. Separation of air chemistry measurements into periods of FT conditions and times of PBL influence requires careful analysis of a variety of datasets on both local and regional scales.

 Material examined. Matua Island, Point Kluv, 15 m, 25.08.2016, two colonies and fragments (#156, 157).
 Description. The specimens form irregular small colonies composed of several separated of fused lobes (Figure 10 B). In live the colonies are colourless, whitish, the superficial layer of the test contains crowded white pigment granules which make the colony opaque. Inner layers of the test are transparent and soft. Large common cloacal openings are on the top of low elevations on the upper surface of colony. Zooids are probably arranged in rows along the cloacal canals converging to common cloacal opening, but this is not quite clear on existing photographs of live colonies.
The zooids are up to 11 mm long with the thorax and abdomen attaining up to 5 mm in better expanded zooids. The branchial siphon is short, six lobed. The atrial languet is simple and short, issued from the upper rim of the atrial opening, which is very small in contracted zooids. The branchial sac has 12 rows of stigmata with 18 or 19 stigmata per row counted in the middle part of the branchial sac (on each side). The stomach is barrel shaped, with 12–14 regular and prominent longitudinal folds. Some zooids have incubated eggs in the atrial cavity, but no developed larvae were found.
 Remarks. The species was known previously only from Kamchatka waters. The colonies from Matua Island are smaller than the colonies from Kamchatka and have less evident systems: in the specimens from Kamchatka the zooids are arranged into distinct double rows along the cloacal canals which are clearly visible in live colonies (see Sanamyan & Sanamyan, 2011, Figure 5). Also, the type specimens from Kamchatka have a bit larger branchial sac (14 rows of stigmata) and slightly more numerous stomach folds (13–15). All these differences are considered here as connected with the smaller size of colonies from Matua Island, however, the identification remains not very reliable and should be confirmed on a material containing larvae.

description: Platelet responses to focal hepatic necrosis were studied using spinning disk confocal intravital microscopy. Platelets instantly adhered to molecularly altered sinusoidal endothelium adjacent to the necrosis paving approximately 200 µm of vessels abutting the injury. Platelets remained accumulated around the necrosis for at least 4 hours but dissipated by 8 hours. GPIIbIIIa was the main adhesive mechanism; GPIb and GPVI were involved at later stages. Platelets did not cause by-stander injury and did not occlude the vessels. Endothelin-induced vasoconstriction via hepatic stellate cells and not the platelet accumulation or coagulation was responsible for temporarily restricted perfusion around the injury. Neutrophil recruitment over four hours to the sterile necrosis was platelet and GPIIbIIIa dependent. As platelets slowly dissipated neutrophil recruitment was also halted. Healing was delayed in GPIIbIIIa deficient mice. We conclude that in localized sterile injury platelets are essential for neutrophil recruitment and subsequent repair of the lesion.
Power Law Distributions of Patents as Indicators of Innovation

description: The total number of patents produced by a country (or the number of patents produced per capita) is often used as an indicator for innovation. Here we present evidence that the distribution of patents amongst applicants within many OECD countries is well-described by power laws with exponents that vary between 1.66 (Japan) and 2.37 (Poland). Using simulations based on simple preferential attachment-type rules that generate power laws, we find we can explain some of the variation in exponents between countries, with countries that have larger numbers of patents per applicant generally exhibiting smaller exponents in both the simulated and actual data. Similarly we find that the exponents for most countries are inversely correlated with other indicators of innovation, such as R&D intensity or the ubiquity of export baskets. This suggests that in more advanced economies, which tend to have smaller values of the exponent, a greater proportion of the total number of patents are filed by large companies than in less advanced countries.

description: We present a new observational campaign, DWARF, aimed at detection of circumbinary extrasolar planets using the timing of the minima of low-mass eclipsing binaries. The observations will be performed within an extensive network of relatively small to medium-size telescopes with apertures of ~20-200 cm. The starting sample of the objects to be monitored contains (i) low-mass eclipsing binaries with M and K components, (ii) short-period binaries with sdB or sdO component, and (iii) post-common-envelope systems containing a WD, which enable to determine minima with high precision. Since the amplitude of the timing signal increases with the orbital period of an invisible third component, the timescale of project is long, at least 5-10 years. The paper gives simple formulas to estimate suitability of individual eclipsing binaries for the circumbinary planet detection. Intrinsic variability of the binaries (photospheric spots, flares, pulsation etc.) limiting the accuracy of the minima timing is also discussed. The manuscript also describes the best observing strategy and methods to detect cyclic timing variability in the minima times indicating presence of circumbinary planets. First test observation of the selected targets are presented.

Compactly Supported Biorthogonal Wavelet Constructions on the A-star Lattice and their Application to Visualization

Year: 2017

description: In this dissertation, a family of compact biorthogonal wavelet filter banks that are tailored to the geometry of the A-star lattice are derived. Our application of interest is on the three dimensional A-star or {\em body centered cubic} (BCC) lattice. While the BCC lattice has been shown to have superior approximation properties for volumetric data when compared to the Cartesian cubic (CC) lattice, there has been little work in the way of designing wavelet filter banks that respect the geometry of the BCC lattice. Since wavelets have applications in signal de-noising, compression, and sparse signal reconstruction, these filter banks are an important tool that addresses some of the scalability concerns presented by the BCC lattice. We use these filters in the context of volumetric data compression and reconstruction and qualitatively evaluate our results by rendering images of isosurfaces from compressed data.
Active Region Moss: Doppler Shifts from Hinode/EIS Observations

description: Studying the Doppler shifts and the temperature dependence of Doppler shifts in moss regions can help us understand the heating processes in the core of the active regions. In this paper we have used an active region observation recorded by the Extreme-ultraviolet Imaging Spectrometer (EIS) onboard Hinode on 12-Dec-2007 to measure the Doppler shifts in the moss regions. We have distinguished the moss regions from the rest of the active region by defining a low density cut-off as derived by Tripathi et al. (2010). We have carried out a very careful analysis of the EIS wavelength calibration based on the method described in Young et al. (2012). For spectral lines having maximum sensitivity between log T = 5.85 and log T = 6.25 K, we find that the velocity distribution peaks at around 0 km/s with an estimated error of 4-5 km/s. The width of the distribution decreases with temperature. The mean of the distribution shows a blue shift which increases with increasing temperature and the distribution also shows asymmetries towards blue-shift. Comparing these results with observables predicted from different coronal heating models, we find that these results are consistent with both steady and impulsive heating scenarios. However, the fact that there are a significant number of pixels showing velocity amplitudes that exceed the uncertainty of 5 km s$^{-1}$ is suggestive of impulsive heating. Clearly, further observational constraints are needed to distinguish between these two heating scenarios.

 Material examined. Matua Island, Point Kluv, 16–17 m, collected at 25– 28.08.2016, three colonies (#153, 160, 169).
 Description. All colonies are small, the largest is 3 cm long, and all are represented by a single head on rather high peduncle and contain from two to five zooids only. The most conspicuous part of colony is a transparent head containing thoraces of the zooids. In the head the zooids are oriented in such a way, that their branchial openings open on the sides of the head and the atrial openings open independently from each other closer to the top of the head (Figure 8 B). The atrial openings have six equal prominent round lobes, the branchial openings also have six lobes, but the dorsal lobe is larger than other, which are low.
The zooids are large and characteristic for this species. They have wide, but relatively short branchial sac with 10 rows of stigmata and about 40 stigmata per row on each side. The abdomen is very long, the stomach is in its posterior end which is filled by parenchymatous tissue. The postabdomen and gonads not present in the material examined, however several zooids contained larvae attached to a placental membrane in the right side of the thorax (Figure 8 C, D). The fully developed larva has a trunk 1.1 mm long. It has thee adhesive organs arranged in a vertical row and has no vesicles or ampullae (Figure 8 E).
 Remarks. In the Sea of Okhotsk and in Kamchatka waters this species may form large, 20 cm and more, heavily branching, tree-like colonies, but all specimens recorded in Matua Island are very small, although some contain fully developed larvae.
 The genus Homoedistoma Redikorzev, 1927 is a synonym, its type species, H. michaelseni Redikorzev, 1927 is conspecific with Placentela crystallina (see Sanamyan, 1993, type revision).

description: The interests in alternative renewable fuels such as syngas and biogas have intensified the search for an accurate chemical kinetics model to describe the combustion of syngas and biogas fuels. Unfortunately, a generally accepted mechanism for the fuels of interest remains elusive. Therefore, this thesis is aimed at developing the most up-to-date chemistry model for syngas and biogas combustion. Based on comprehensive comparison between several notable mechanisms available in the literature, the NUIG2013 mechanism [1] was found to have the closest agreement with the experimental data for H2 –CO–CH4 –CO2 fuel mixtures diluted with N2 and H2O. However, the NUIG2013 mechanism failed to predict accurately the ignition delay time at several experimental conditions and the NUIG2013 consists of too many irrelevant species and reactions for syngas and biogas combustion purpose. Therefore, sensitivity analysis were conducted to identify the cause of discrepancies observed between the predicted results and experimental data, and Genetic Algorithm (GA) approach was proposed and validated to optimally extract relevant reactions for H2/CO/CH4/CO2 mixtures from the detailed NUIG2013 chemical kinetics mechanism. Two new rate constants for H+O2(+CO2) = HO2(+CO2) and CH4+OH = CH3+H2O reactions were proposed based on the sensitivity analysis, and it was found that the modified rate constants reconciled the observed discrepancies between the predicted and the measured results. The GA eliminated 1777 insensitive reactions in the NUIG2013 mechanism [1], where the final detailed chemical kinetics model presented in this thesis for biogas/syngas fuel mixtures comprised of 290 reactions and 72 species. The final detailed chemical kinetics model with the incorporation of the two modified rate constants was validated against a large set of experimental data, and excellent agreements were found between the predicted and experimental data. Consequently, the final mechanism presented in this thesis is currently the most up-to-date detailed chemical kinetics mechanism that is suitable for predicting the combustion properties of biogas/syngas accurately.

Significant polarization squeezing at the threshold level (-3dB) required for the implementation of several continuous variables quantum protocols was observed. The extreme simplicity of the setup, based on standard polarization components, makes it particularly convenient for quantum information applications.

description: This preregistration outlines a project on the relation between math and spatial skills in a sample of approximately 600 first grade students across two waves of data collection. This project centers around two main research questions. For Research Question 1 - Aim 1 the goal is to examine the relation between spatial and math skills over two waves of data collection and, more specifically, examine if early spatial skills predict later math skills, early math skills predict later spatial skills, or both (indicating bidirectional relations). For Research Question 1 - Aim 2 we will examine if the relations between spatial and math skills remain significant when accounting for reading skills. For Research Question 2 - Aim 1 we will identify if spatial and math anxiety at Wave 1 predict spatial and math skills at Wave 2, with particular interest in examining if cognitive anxieties exhibit domain-specificity (i.e., math anxiety being more predictive of math skills than spatial skills) in their relations with children’s cognitive performance. For Research Question 2 - Aim 2 we will address if any relations between cognitive anxieties and skills remain significant when accounting for reading skills.

This may involve the relocalization of host proteins away from their original subcellular targets to sites which may benefit the virus, a process that is not as well understood as it relates to the nucleus. To identify nuclear proteins that may be involved in such processes, a library of random Nicotiana benthamiana cDNAs were expressed as GFP fusions in a transgenic marker lines expressing a histone 2B:RFP nuclear marker. Of the 1,087 proteins screened, 355 were found to be associated with the nucleus. These nuclear proteins were then expressed in plants infected with sonchus yellow net virus, a betanucleorhabdovirus which forms its replication complex in the nucleus. Of the 355 nuclear-associated proteins, 15 were found to relocalize in response to SYNV infection, and to test if this phenomenon was virus-specific, these proteins were then expressed in plants infected with tobacco etch virus (TEV), a potyvirus which replicates in the cytoplasm. Of these 16 proteins, 6 were found to show both general and virus-specific localization patterns between the two viruses. To gain insight into the cellular tropism of SYNV, a cell map was generated in order determine the effect of this virus on membranes in N. benthamiana tissues. Finally, sowthistle yellow vein virus (SYVV), another betanucleorhabdovirus and classical model virus, was identified in the wild for the first time in over 30 years. Sequence and phylogenetic analysis confirmed the identity of this virus with historical laboratory isolates. The availability of SYVV will facilitate future studies that compare the effect of rhabdovirus infection on host nuclear proteins and membranes.

description: We present here a method for the relativistic positioning in spacetime based on the reception of pulses from sources of electromagnetic signals whose worldline is known. The method is based on the use of a four-dimensional grid covering the whole spacetime and made of the null hypersurfaces representing the propagating pulses. In our first approach to the problem of positioning we consider radio-pulsars at infinity as primary sources of the required signals. The reason is that, besides being very good clocks, pulsars can be considered as being fixed stars for reasonably long times. The positioning is obtained linearizing the worldline of the observer for times of the order of a few periods of the signals. We present an exercise where the use of our method applied to the signals from four real pulsars permits the reconstruction of the motion of the Earth with respect to the fixed stars during three days. The uncertainties and the constraints of the method are discussed and the possibilities of using moving artificial sources carried around by celestial bodies or spacecrafts in the Solar System is also discussed.

description: The prevalent need for publicly available data set along with the privacy-breach-related incidents occurring when such data is released, increases the need to develop resilient and precise techniques of privacy-preserving data publishing. To this end, numerous privacy models and algorithms have been developed for different data types. However, advances in privacy algorithms still suffer from two fundamental problems: data dimensionality and cardinality growth. The data dimensionality has remained a challenge for a wide variety of algorithms in data mining, clustering, classification and privacy. In the privacy domain, simply applying the existing privacy algorithms results in unacceptable information loss. Similar to the dimensionality problem, cardinality growth is an open problem in the privacy realm. In fact, privacy algorithms are not implementable in an acceptable time over tera-byte scale data sets. This thesis shows that some of the common properties of real data can be leveraged to ameliorate the negative effects of the curse of dimensionality in practice. In real data sets, many dimensions contain high levels of inter-attribute correlations. Such correlations enable the use of a process known as vertical fragmentation to create vertical subsets of smaller dimensionality. This allows the use of an anonymization process, which is based on combining results from multiple independent fragments. This dissertation presents a vertical fragmentation which is general enough to be applied to the k-anonymity and l-diversity models. In addition, this dissertation presents a new approach to privacy-preserving data mining of very massive data sets using MapReduce. Two of the most widely-used privacy models k-anonymity and l-diversity for anonymization are studied. We also investigate the privacy issue in publishing graph data commonly seen as big data sets (i.e. social networks). Graph data is generally more difficult to anonymize because the structural information “hidden” in the graph can be leveraged by an attacker to infer sensitive information. In big graph data publishing, we only focus on protecting attributes as they typically carry sensitive information.

description: Jaynes-Cummings-Hubbard arrays provide unique opportunities for quantum emulation as they exhibit convenient state preparation and measurement, and in-situ tuning of parameters. We show how to realise strongly correlated states of light in Jaynes-Cummings-Hubbard arrays under the introduction of an effective magnetic field. The effective field is realised by dynamic tuning of the cavity resonances. We demonstrate the existence of Fractional Quantum Hall states by com- puting topological invariants, phase transitions between topologically distinct states, and Laughlin wavefunction overlap.

description: Mass-action kinetics is frequently used in systems biology to model the behaviour of interacting chemical species. Many important dynamical properties are known to hold for such systems if they are weakly reversible and have a low deficiency. In particular, the Deficiency Zero and Deficiency One Theorems guarantee strong regularity with regards to the number and stability of positive equilibrium states. It is also known that chemical reaction networks with disparate reaction structure can exhibit the same qualitative dynamics. The theory of linear conjugacy encapsulates the cases where this relationship is captured by a linear transformation. In this paper, we propose a mixed-integer linear programming algorithm capable of determining weakly reversible reaction networks with a minimal deficiency which are linearly conjugate to a given reaction network.

Unified Simulation Methodology and Project Risk Assessment Framework

subject: Risk Assessment

description: Simulation applications in construction-project management are primarily limited to academic research. Where simulation has been used in project risk assessment in the industry, it has not been used to its potential. This research addresses two problems: the difficulty associated with using simulation, and the lack of project risk models that correctly reflect the risk identification assumptions. Surveys show that facilitating the modelling process and reducing programming efforts are the most important factors in increasing the appeal to simulation. Large models are impractical for standalone computers. Simulation methodologies serving construction projects are built around the cyclic operations that do not support seamless data transfer between the models and the data storage media. Project management systems are data driven where data are updated regularly, making it difficult to simultaneously keep models current. Project risk management attempts to increase the chances of achieving project objectives; however, simulation-based risk-assessment models use range estimates that do not reflect the causal relationship between the risk events and the objectives’ outcomes. The literature on risk assessment recommends integration between risk-assessment tools and those of cost and schedule management. However, current simulation-based risk-assessment applications are standalone models built around the independent creation of random numbers that do not support integration within the project or within a portfolio of projects. This research has two objectives: increasing the appeal of simulations and facilitating the modeling process, and measuring project risks in an integrated environment. The researcher identified criteria that improve current simulation methodologies and simulation-based risk assessment methods, and developed the computer applications that incorporate these criteria. The simulation methodology provides a user-friendly interface with a built-in code generation and database integration for standalone and distributed models. The risk assessment framework allows the effects of risks on projects and portfolio objectives to be measured in an integrated environment. The risk assessment model was used by graduate students at the University of Calgary as part of the verification and validation process. Feedback from students confirmed that the simulation methodology increases the appeal to simulation and that calculating risk effects using the proposed framework produces better risk assessment than range estimate
