Path dependent : Canada and Great Britain's immigration policies 1945 - present
Creators: name: Woznow, Vanessa
Publisher: name: University of British Columbia
Year: 2010

description: After the end of the Second World War both Great Britain and Canada’s immigration policies underwent significant reforms. Great Britain’s transition from country of empire and emigration to independent, immigration nation was met with great resistance on the part of both British society and its government. Racially restrictive legislation aimed at limiting the number of New Commonwealth immigrants was introduced, an action that immediately clashed with Britain’s system of inclusive Commonwealth citizenship. Canada on the other hand implemented liberalizing, non-discriminatory reforms that offered all individuals irrespective of race the opportunity to immigrate, as long as they possessed the human capital required to succeed in Canadian society. This thesis uses the concept of path dependence to explain why, despite strong historical and cultural connections, Canada and Great Britain introduced disparate post-war immigration policies. Historical analysis reveals how both countries’ legislation mirrored socially embedded attitudes and norms, and illustrates the difficulty countries face in an effort to break away from historically accepted and propagated systems and conditions. Britain’s policies were influenced by the historical institution of “Empire,” while Canada’s were motivated by its dependence on immigration for economic prosperity and national unity.

description: A reliable method was developed for sulfur isotopic composition measurements of sulfur solutions (10 ppm) using a 20 mL cyclonic quartz spray chamber and 50 μL/min (Glass Expansion Inc.) quartz nebulizer coupled to a high mass resolution Multiple Collector Inductively Coupled Plasma Mass Spectrometry (MC-ICP-MS). The repeatability of the method was tested which three reference materials (IAEA S-1, IAEA S-2, and IAEA S-3) and the ability to measure sulfur isotopic variations in hair sample was evaluated. The n(34S)/n(32S) and n(33S)/n(32S) isotope amount ratios were measured free from isobaric interferences (e.g. 16O2+ on 32S+ and 32S1H+ on 33S+) and corrected for instrumental mass bias adopting the standard-sample bracketing approach. The reproducibility of IAEA S-2 and IAEA S-3 is typically ± 0.19 ‰ and ±0.52 (2sd) for δ34S and δ33S, respectively and ± 0.30 ‰ and ± 0.53 ‰ (2sd) for δ34S and δ33S, respectively. Freedom from isobaric interferences was verified by plotting δ34S vs. δ33S. Cleanliness of the spray chamber was found to be extremely important to achieve reliable data. A microwave digestion method was developed to analyze sulfur in hair samples. The reproducibility of hair samples was typically ± 0.45 ‰ and ± 0.75 ‰ (2sd) for δ34S and δ33S values, respectively. Achieving a reliable method for δ34S and δ33S measurements will enable now a high precision measurement of sulfur isotopic composition.

description: An ageing population leads to challenges in long-term care homes such as social isolation in multi-cultural communities. While working in Mumbai, India, I observed this social isolation of seniors in long-term care homes first-hand. Familial and financial limitations are insufficient in providing seniors shelters in their own homes, leading to greater demand for ‘nursing homes’ in India. The seniors in care homes with smaller populations were more likely to quickly find relationships among their neighbours. In larger-scale care homes hosting more than 100 seniors, the feeling of institutions, unfamiliarity kept the seniors socially disconnected, in Mumbai as well as the care homes I visited in Vancouver, BC. The policies about eldercare are not updated, leading to insufficient resources and outdated norms. As part of my MDes research, I also visited De Hogeweyk (a dementia village) in the Netherlands. I used methods like observational research, fly on the wall, and interviews with the management members. As a designer, I explored and made iterative design objects and experiences for human-human and human-nature connections. This thesis describes design research activities and prototypes such as guided outdoor walking and reflection practices, using peer designers as proxy participants. I describe my service design workshops and architectural space and layout discussions. This thesis work includes historical perspectives and personal reflection on nature-human connections such as described in the Bhagavad Gita and practiced in traditional Ikebana. One significant insight through the research was that experiencing time in nature might solve institutional issues, whether in India, Vancouver, or the Netherlands. The second important lesson learned as a designer, addresses how time pressure makes people take shortcuts, such as overlooking the importance of material in concept review and testing and too little or too much preparation in developing interview scripts and protocols. The research also reflects on iterations of different design concepts, repeating and improving, recognizing the failures and appreciating them. It is an essential step as a designer to learn from the process, especially when it is imperfect. Lastly, through this research, I found that nature, space, memory and social connection are interconnected, intricately woven together to help humans survive independently and with fellowship.

Against the Tide: A Biography of Dr. Marie Olive Reay
Creators: name: Gates, Erin
Publisher: name: The Australian National University
Year: 2023

description: Dr. Marie Olive Reay (1922-2004) was a pioneering anthropologist and a leading contributor to Australian and Pacific anthropology. She was the first to study contemporary conditions of Aboriginal communities in rural NSW, as well as the first woman to conduct extensive fieldwork in the Highlands region of PNG. However, she often expressed in her personal wrings, that her work in the male dominated field of anthropology was undervalued and over-managed as a direct result of her gender. Drawing primarily from her substantial collection of unpublished writings, correspondence and field notes, this thesis seeks to produce a feminist biography of Reay that captures her contribution to the discipline of anthropology, her tremendous spirit, as well as her defiance of and critical outlook towards the societal expectations of women during her lifetime. Through the methodology of feminist biography, the research draws upon theory from the fields of anthropology, feminism, gender relations, and queer studies in order to analyse the impacts of gender and power upon Reay's career. This will be illustrated not only by the ways in which Reay was acted upon by others, but also by how Reay chose to navigate her positionality as a queer, female anthropologist in a male dominated discipline. Using the framework of the scholarly persona, with Reay's life as a medium, the ensuing narrative navigates within and between the personal and the professional in order to articulate the complicated position of a female academic in Australia in the mid-late twentieth century. The research will illustrate not only the lasting importance of Reay's work to the historical record, but also contextualise the highly toxic environment in which she completed it. What emerges are reoccurring patterns of sexism and misogyny, the consequences of which had a long-term deleterious effect on Reay's mental health. While Reay herself is the subject of this thesis, her story as an individual helps to illuminate the much larger system of structural discrimination and disadvantage leveraged against her and other early female scholars during the mid to late twentieth century.

description: EK Eri is one of the most slowly rotating active giants known, and has been proposed to be the descendant of a strongly magnetic Ap star. We have performed a spectropolarimetric study of EK Eri over 4 photometric periods with the aim of inferring the topology of its magnetic field. We used the NARVAL spectropolarimeter at the Bernard Lyot telescope at the Pic du Midi Observatory, along with the least-squares deconvolution method, to extract high signal-to-noise ratio Stokes V profiles from a timeseries of 28 polarisation spectra. We have derived the surface-averaged longitudinal magnetic field Bl. We fit the Stokes V profiles with a model of the large-scale magnetic field and obtained Zeeman Doppler images of the surface magnetic strength and geometry. Bl variations of up to about 80 G are observed without any reversal of its sign, and which are in phase with photometric ephemeris. The activity indicators are shown to vary smoothly on a timescale compatible with the rotational period inferred from photometry (308.8 d.), however large deviations can occur from one rotation to another. The surface magnetic field variations of EK Eri appear to be dominated by a strong magnetic spot (of negative polarity) which is phased with the dark (cool) photometric spot. Our modeling shows that the large-scale magnetic field of EK Eri is strongly poloidal. For a rotational axis inclination of i = 60°, we obtain a model that is almost purely dipolar. In the dipolar model, the strong magnetic/photometric spot corresponds to the negative pole of the dipole, which could be the remnant of that of an Ap star progenitor of EK Eri. Our observations and modeling conceptually support this hypothesis, suggesting an explanation of the outstanding magnetic properties of EK Eri as the result of interaction between deep convection and the remnant of an Ap star magnetic dipole.

description: We present evidence for the presence of a weak compact jet during a soft X-ray state of Cygnus X-1. Very-high-resolution radio observations were taken with the VLBA, EVN and MERLIN during a hard-to-soft spectral state change, showing the hard state jet to be suppressed by a factor of about 3-5 in radio flux and unresolved to direct imaging observations (i.e. < 1 mas at 4 cm). High time-resolution X-ray observations with the RXTE-PCA were also taken during the radio monitoring period, showing the source to make the transition from the hard state to a softer state (via an intermediate state), although the source may never have reached the canonical soft state. Using astrometric VLBI analysis and removing proper motion, parallax and orbital motion signatures, the residual positions show a scatter of ~0.2 mas (at 4 cm) and ~3 mas (at 13 cm) along the position angle of the known jet axis; these residuals suggest there is a weak unresolved outflow, with varying size or opacity, during intermediate and soft X-ray states. Furthermore, no evidence was found for extended knots or shocks forming within the jet during the state transition, suggesting the change in outflow rate may not be sufficiently high to produce superluminal knots.

description: This study set out to determine tetracycline and erythromycin resistance profiles and detect various tetracycline (tetB, tetC, tetL, tetM, tetQ and tetW) or erythromycin (ermA, ermB and ermF) resistance determinants from clinical isolates of bovine foot rot bacteria isolated from affected animals in Alberta. Using agar dilution assay, we determined that 82% (32/39) of Fusobacterium necrophorum were tetracycline resistant and 62% (24/39) were classified intermediate to erythromycin. Approximately 82% (18/22) and 91% (20/22) of Prevotella melaninogenica was sensitive to tetracycline and erythromycin respectively, For Porphyromonas levii, 88% (21/24) were sensitive to tetracycline and 100% (24/24) were erythromycin sensitive. Polymerase chain reaction amplification revealed that tetC, tetL, tetM and ermF were commonly detected in F.necrophorum, and tetQ in Pr.melaninogenica and P.levii. Special resistance determinant patterns were not observed in antibiotic resistant strains compared to sensitive isolates in all three pathogens because as high as 90% of resistance determinants were detected in both resistant and sensitive strains of bacteria.

description: Purpose: To determine the role of the collagen binding receptor integrin α1β1 in regulating chondrocyte osmotransduction. Methods: The [Ca2+]i transient response of wildtype and integrin α1-null chondrocytes to osmotic stress was measured ex vivo and in vitro using real-time confocal microscopy. Immunocytochemistry was performed to detect the presence of the osmosensor, transient receptor potential vanilloid 4 (TRPV4), and the agonist GSK1016790A (GSK101) was used to test for its functionality. Results: Deletion of the integrin α1 subunit inhibited the ability of chondrocytes to respond to a hypo-osmotic stress ex vivo and in vitro. TRPV4 protein was expressed by both wildtype and integrin α1-null chondrocytes, however TRPV4 could only be activated on wildtype chondrocytes. Conclusion: Integrin α1β1 is a key participant in chondrocyte transduction of a hypo-osmotic stress. Furthermore, the mechanism by which integrin α1β1 influences osmotransduction is independent of matrix binding, but likely dependent on the chondrocyte osmosensor TRPV4.

description: A unified model of voltage mode control (VMC) and current mode control (CMC) is proposed to predict the saddle-node bifurcation (SNB). Exact SNB boundary conditions are derived, and can be further simplified in various forms for design purpose. Many approaches, including steady-state, sampled-data, average, harmonic balance, and loop gain analyses are applied to predict SNB. Each approach has its own merits and complement the other approaches.

Mitochondrial potassium sequestration and neuroprotection is mediated by connexin43
Creators: name: Kozoriz, Michael Gregory
Publisher: name: University of British Columbia
Year: 2010

description: Reduction in the expression of the astrocyte gap junction protein connexin43 (Cx43) increases infarct volume following middle cerebral artery occlusion (MCAO). A potential mechanism for this effect is disruption of ion buffering. During ischemia, extracellular potassium concentration ([K⁺]₀) rises, leading to a variety of potentially detrimental effects on neuronal function. It is known that astrocytes contribute to the clearance of K⁺o to neighbouring cells through Cx43 based gap junctions, but mitochondria also contain Cx43 which could play a role in K⁺ uptake. Mitochondrial K⁺ sequestration was examined by loading astrocytes with the fluorescent K⁺ indicator PBFI. Release of K⁺ from mitochondria into the cytoplasm was examined after uncoupling the mitochondrial membrane potential with carbonyl cyanide m-chlorophenylhydrazone (CCCP). Transient applications of elevated [K⁺]₀ led to increases in K⁺ within mitochondria, as assessed by increases in the magnitudes of cytoplasmic [K⁺] ([K⁺]i) transients evoked by brief exposures to CCCP. When mitochondrial K⁺ sequestration was impaired by prolonged application of CCCP, there was a robust increase in [K⁺]i upon exposure to elevated [K⁺]₀. Blockade of plasmalemmal K⁺ uptake routes by ouabain, Ba²⁺, or a cocktail of voltage-activated K⁺ channel inhibitors reduced K⁺ uptake into mitochondria. Reductions in mitochondrial K⁺ uptake occurred in the presence of the mitoKATP channel inhibitor 5-hydroxydecanoic acid. Rises in [K⁺]i evoked by brief applications of CCCP following exposure to high-[K⁺]₀ were also reduced by gap junction blockers and in astrocytes isolated from Cx43-null mice, suggesting that connexins also play a role in K⁺ uptake into astrocyte mitochondria. In a second study, the carboxy-terminal (CT) region of Cx43, a region important for channel activity, was explored in mutant mice expressing a truncated form of Cx43 (Cx43ΔCT mice). These mice exhibit enhanced cerebral injury following MCAO. In the peri-infarct region, astrogliosis was reduced and inflammatory cell invasion was increased. Cultured astrocytes from Cx43ΔCT mice were less coupled, and displayed alterations in channel gating, hemichannel activity, Ca²⁺ wave properties and showed impairment of mitochondrial K⁺ sequestration. These results suggest that astrocytic Cx43 contributes to the mitochondrial sequestration of K⁺ and that the CT region plays an important role in protection following stroke.

TCP-Aware Scheduling in LTE Networks
Creators: name: Shojaedin, Narges
Publisher: name: Graduate Studies
Year: 2014
Subjects: subject: Computer Science
subject: Wireless Networking

description: Designing scheduling algorithms that work in synergy with TCP is a challenging problem. In this thesis, we focus on Max Weight (MW) schedulers and show that contrary to its performance with inelastic traffic, MW schedulers may not perform well in LTE networks in the presence of TCP traffic. We then design two new schedulers which both are based on MW. The first proposed scheduler, called Q-MW, is tailored to TCP dynamics by giving higher priority to TCP flows whose queue at the base station is very small to encourage them to send more data at a faster rate. The second proposed scheduler is named H-MW in which some of the subcarriers with low channel quality are left unassigned to improve the total MW scheduler throughput. In the last part of the thesis, we consider how LTE handovers affect the performance of scheduling algorithms under TCP traffic.

description: This thesis explores parenting advice literature directed to parents of young children. My research includes investigating parents’ experiences and responses to reading and what prominent messages can be found within popular sources. To explore this topic, I used two main methods. First, I conducted in-depth interviews with mothers and fathers about what they had read in terms of parenting advice. Second, I analyzed a selection of popular parenting books to explore what messages they were conveying. Both of these approaches revealed that parenting advice remains highly gendered. Mothers were portrayed as the primary caregiver and fathers as the mothers’ assistant. In terms of their responses to these expectations, the parents I interviewed demonstrated agency by actively selecting which pieces of advice to accept and which to reject. This agency also had a gendered dimension, as mothers were the ones taking on the work of customizing the advice for their family.

description: Boron (B) alloying transforms the magnetoelectric antiferromagnet Cr2O3 into a multifunctional single-phase material which enables electric field driven π/2 rotation of the Néel vector. Nonvolatile, voltage-controlled Néel vector rotation is a much-desired material property in the context of antiferromagnetic spintronics enabling ultra-low power, ultra-fast, nonvolatile memory, and logic device applications. Néel vector rotation is detected with the help of heavy metal (Pt) Hall-bars in proximity of pulsed laser deposited B:Cr2O3 films. To facilitate operation of B:Cr2O3-based devices in CMOS environments, the Néel temperature, TN, of the functional film must be tunable to values significantly above room temperature. Cold neutron depth profiling and x-ray photoemission spectroscopy depth profiling reveal thermally activated B-accumulation at the B:Cr2O3/ vacuum interface in thin films deposited on Al2O3 substrates. We attribute the B-enrichment to surface segregation. Magnetotransport data confirm B-accumulation at the interface within a layer of about 50 nm thick where the device properties reside. Here TN enhances from 334 K prior to annealing, to 477 K after annealing for several hours. Scaling analysis determines TN as a function of the annealing temperature. Stability of post-annealing device properties is evident from reproducible Néel vector rotation at 370 K performed over the course of weeks.

description: The H II regions LMC N191 and SMC N77 are among the outermost massive star-forming regions in the Magellanic Clouds. So far, few works have dealt with these objects despite their interesting characteristics. We aim at studying various physical properties of these objects regarding their morphology (in the optical and Spitzer IRAC wavelengths), ionized gas emission, nebular chemical abundances, exciting sources, stellar content, age, presence or absence of young stellar objects, etc. This study is based mainly on optical ESO NTT observations, both imaging and spectroscopy, coupled with other archive data, notably Spitzer images (IRAC 3.6, 4.5, 5.8, and 8.0 microns) and 2MASS observations. We show the presence of two compact H II regions, a low-excitation blob (LEB) named LMC N191A and a high-excitation blob (HEB) named SMC N77A, and study their properties and those of their exciting massive stars as far as spectral type and mass are concerned. We also analyze the environmental stellar populations and determine their evolutionary stages. Based on Spitzer IRAC data, we characterize the YSO candidates detected in the direction of these regions. Massive star formation is going on in these young regions with protostars of mass about 10 and 20 M_sun in the process of formation.

description: Background: Cardiac rehabilitation reduces mortality and subsequent cardiac events in patients with coronary heart disease. While economic evaluations of cardiac rehabilitation have been published, none consider clinical, age and sex subgroups to demonstrate how the cost-effectiveness varies. Methods: We performed a cost-utility analysis comparing cardiac rehabilitation with no cardiac rehabilitation, for patients who had a cardiac catheterization, using a health system payer perspective. The model was stratified by clinical presentation, age and sex. Clinical, quality of life and cost data were provided by the Alberta Provincial Project for Outcome Assessment in Coronary Heart Disease (APPROACH) and TotalCardiology. Data on efficacy was obtained from a meta-analysis of randomized controlled trials. Results: The incremental cost per quality-adjusted life year (QALY) gained for cardiac rehabilitation is $37,662. The incremental cost per QALY gained varies by subgroup, from $18,101 per QALY gained to $104,518 per QALY gained. There is significant uncertainty in the estimates due to uncertainty in the clinical effectiveness of cardiac rehabilitation. Overall, the probabilistic sensitivity analysis found that 75% of the time, cardiac rehabilitation is more effective and expensive than no cardiac rehabilitation. Conclusions: The cost-effectiveness of cardiac rehabilitation varies depending on patient characteristics. However, irrespective of baseline characteristics, the cost per QALY gained for cardiac rehabilitation is less than or similar to other technologies funded in many health systems. The current analysis indicates that cardiac rehabilitation is most cost effective for those who suffered an ACS and those who are at higher risk for subsequent cardiac events. The findings of the current study provide insight into who may benefit most from cardiac rehabilitation, with important implications for patient referral patterns.

description: In the field of medical image analysis, achieving high accuracy is not enough; ensuring well-calibrated predictions is also crucial. Confidence scores of a deep neural network play a pivotal role in explainability by providing insights into the model's certainty, identifying cases that require attention, and establishing trust in its predictions. Consequently, the significance of a well-calibrated model becomes paramount in the medical imaging domain, where accurate and reliable predictions are of utmost importance. While there has been a significant effort towards training modern deep neural networks to achieve high accuracy on medical imaging tasks, model calibration and factors that affect it remain under-explored. To address this, we conducted a comprehensive empirical study that explores model performance and calibration under different training regimes. We considered fully supervised training, which is the prevailing approach in the community, as well as rotation-based self-supervised method with and without transfer learning, across various datasets and architecture sizes. Multiple calibration metrics were employed to gain a holistic understanding of model calibration. Our study reveals that factors such as weight distributions and the similarity of learned representations correlate with the calibration trends observed in the models. Notably, models trained using rotation-based self-supervised pretrained regime exhibit significantly better calibration while achieving comparable or even superior performance compared to fully supervised models across different medical imaging datasets. These findings shed light on the importance of model calibration in medical image analysis and highlight the benefits of incorporating self-supervised learning approach to improve both performance and calibration.

description: Objectives The objective of the research was to explore the possible relationships of commonly used pain measures in women suffering from vulvar pain. Methods Characterization of the pain profiles of a twenty women cohort presenting with vulvar pain was undertaken. Descriptive analysis was used to describe the cohort. Scatter plots were used to explore the relationships between the vulvalgesiometer pain thresholds, the McGill Pain Questionnaire responses and modified visual analogue scale scores. Spearman’s correlation coefficient of Rho greater than eight was considered important. Results The cohort was representative of the spectrum of women suffering from vulvar pain. There was no correlation between the different pain measures. This was seen on scatter plots and confirmed with Spearman correlation coefficients less than eight. Conclusion There is no correlation between the commonly used pain measures in women presenting with vulvar pain. Better characterization and understanding of women suffering from vulvar pain is required.

description: This paper outlines an emerging methodology that links separate art projects made in multiple locations. Accumulation (of both materials and experiences over time) combined with a process of interruption serve as a common line of enquiry that reflects both my past and present situations as a temporary resident in a foreign country. Through a psycho-geographical and phenomenological lens the work uses the experience of movement through a landscape (natural or urban) as a site where the visual and haptic sensory information imprints itself in the mind. Mapping, tracking and recording these experiences points towards a broader engagement with ideas about attachment to places that are not yet home. My work utilizes the methods of layering, collage and assemblage as a means to visualize and contrast our complicated experiences of time that cross borders and continents in a highly mobile and technological society. I ask what can be learned by questioning our connections to place and how do these experiences contribute to our sense of belonging? How do we carry these experiences with us to create continuity between places, past, present and future? Filtered through the ambiguity of memory I build upon patterns of association, trusting in intuitive yet controlled responses where the work becomes a site to explore our permanent and temporary relationships to place.

description: Chronic Wasting Disease (CWD) is a fatal neurological disease affecting cervids caused by prions. Infected cervids shed the CWD prion in bodily fluids and excrement, contaminating the environment and creating an agricultural and ecological calamity. Preclinical antemortem CWD testing method is demanded by CWD risk management programs. In vitro PrP-conversion assays have been developed as potential tools for such an approach with increasing sensitivity for prion detection. However, no method has been routinely employed thus far. Timing recombinant-PrP conversion into amyloid fibrils, seeded by elk CWD prion, as a diagnostic method is presented herein. The assay, termed “RePLICA”, is at least as sensitive for detecting elk CWD in brain tissues as Tg(CerPrP-M132)1536+/- and Tg(CerPrP-E226)5037+/- mouse bioassay models. The assay performs within a period of 35 hours, is consistently reproducible, and functions on elk brain and tonsil tissues. There are indications RePLICA has the potential to titre CWD infectivity.

description: Any non-gravitational coupling between dark matter and dark energy modifies the cosmological dynamics. Interactions in the dark sector are considered to be relevant to address the coincidence problem. Moreover, in various models the observed accelerated expansion of the Universe is a pure interaction phenomenon. Here we review recent approaches in which a coupling between both dark components is crucial for the evolution of the Universe.

description: This study introduces a novel forecasting strategy that leverages the power of fractional differencing (FD) to capture both short- and long-term dependencies in time series data. Unlike traditional integer differencing methods, FD preserves memory in series while stabilizing it for modeling purposes. By applying FD to financial data from the SPY index and incorporating sentiment analysis from news reports, this empirical analysis explores the effectiveness of FD in conjunction with binary classification of target variables. Supervised classification algorithms were employed to validate the performance of FD series. The results demonstrate the superiority of FD over integer differencing, as confirmed by Receiver Operating Characteristic/Area Under the Curve (ROCAUC) and Mathews Correlation Coefficient (MCC) evaluations.
Seismic Depth Imaging in Anisotropic Media

description: Our ultimate goal of seismic data processing is to produce seismic images with correct lateral and vertical positions, and with amplitude proportional to the reflection coeffi- cients in the subsurface. A good migrated image depends strongly on the accuracy of the velocity model. Prestack depth migration (PSDM) is a powerful tool not only for imaging but also for velocity model building. The main techniques used for migration velocity analysis include vertical updating and tomography analysis , including anisotropy parameters estimation. To achieve the goal of accurately positioning the seismic events in subsurface, the velocity anisotropy should be accounted for. If the presence of velocity anisotropy is important, then ignoring it will significantly degrade the final image accuracy. This thesis examines a frontier exploration survey acquired off the East Coast of Canada by Statoil Canada Ltd. and processed by CGG. Kirchhoff isotropic PSDM and tilted transverse isotropy (TTI) PSDM were conducted with the goals of good imaging and good velocity estimation. Structural interpretation and Amplitude Versus Offset (AVO) analysis for this survey demonstrate the benefits of TTI PSDM, whose subsurface images significantly reduced the exploration risk compared with isotropic PSDM. Estimation of reliable anisotropy parameters is challenging, especially for the survey studied in this thesis where no well information is available. This thesis presents a practical production method for building five parameter fields needed for TTI PSDM: p- wave velocity, Thomsen’s anisotropy parameters and the angles describing the symmetry axis of the anisotropy. This method includes 1D joint inversion (Huang, 2007) to estimate anisotropy parameter and high resolution tomography (Hu, 2011) to obtain accurate velocity models.

description: This thesis presents a study of the four-wave mixing process in hot Rubidium vapor and its applicability to generating arbitrary quantum states, both in the optical domain and as atomic collective spin excitations. The four-wave mixing process involves a double Raman scattering event, where conservation of energy and momentum entangle these Raman-scattered photons. Heralding upon detection of one of these photons in a given mode projects the other photon onto a single photon Fock state in a well-defined mode, which may serve as a narrowband quantum light source that is compatible with atom-based quantum communication protocols. We integrate the existing technique of conditional measurements into our detection scheme, which allows us to engineer more complex quantum states. Experimentally we demonstrate the production of arbitrary superpositions of |0> and |1> in the optical Fock basis. We also present a theoretical model of this process which incorporates experimental complications such as losses, higher photon-number states, and a non-trivial temporal mode. This scheme can be extended to generate arbitrary quantum states with increasing photon numbers, at the expense of repetition rate. The atomic nature of this four-wave mixing process has an added benefit in that it allows access to excitations of the collective atomic ensemble. The optical results demonstrate the creation of transient collective spin excitations, and we present a proposal to extend this work to generate longer lived arbitrary collective atomic states.
Bias in generation of random graphs

description: We study the statistical properties of the generation of random graphs according the configuration model, where one assigns randomly degrees to nodes. This model is often used, e.g., for the scale-free degree distribution ~d^gamma. For the efficient variant, where non-feasible edges are rejected and the construction of a graph continues, there exists a bias, which we calculate explicitly for a small sample ensemble. We find that this bias does not disappear with growing system size. This becomes also visible, e.g., for scale-free graphs when measuring quantities like the graph diameter. Hence, the efficient generation of general scale-free graphs with a very broad distribution (gamma <2) remains an open problem.

description: Dukagjinis in the Middle Ages. The Geographical Area and some Characteristics. In this article is tried will try to give a general overview of the history of Dukagjinis which consisted of some families seemingly belonging to the same tribe and were part of the Albanian nobles in the Middle Ages. Dukagjinis show up many times in documents, and they were an essential factor in the occurrences taking place in Albania in the Middle Ages, especially during Skanderbeg's period. Besides the expansion of their prevalence in North Albanian regions and their distribution into some European countries after the Ottoman occupation, they result to be present even among noble Albanian families with the highest duration until they died out in the 17th century. In this paper, besides the historical data about them in Albanian territories, the reader will also find information on their presence in Italy, Istria and the Ottoman Empire.

description: Informed by my personal experience with organized religion and conditioned ideologies, my photo-based practice aims to explore my position as a female photographer who contributes to the commodification and consumption of women’s images while also undermining and complicating standard and stereotypical versions of female narrative. In this paper, I unpack the impact of my personal history with Evangelicalism, the importance of nature as a reoccurring motif in my images, the role of the camera and photographic exploration, and the trajectory of my practice as established by my thesis photo series titled "Finding The Pieces".
The Development of an Analytical Technique to Measure Stable and Radiogenic Strontium Isotope Ratios Using Thermal Ionization Mass Spectrometry with the Double Spike Method

description: An analytical method using a strontium “double spike” enriched in both 84Sr and 87Sr was developed to measure the n(87Sr)/n(86Sr) and n(88Sr)/n(86Sr) isotope ratios using a thermal ionization mass spectrometer. The results obtained for the SRM987 reference material using this technique are in agreement with published data. However, the results of IAPSO sea water standard revealed an enrichment in the n(88Sr)/n(86Sr) isotope ratio relative to SRM987 of 0.04 % and n(87Sr)/n(86Sr) isotope ratio of 0.709325(27), which is significantly different from the n(87Sr)/n(86Sr) ratio of 0.709191(37), which is found when one assumes a fixed n(88Sr)/n(86Sr) isotope ratio, as has been done in the past. The use of a double spike method for measuring strontium isotopic composition reveals important insights into mass dependent processes that occur as this element moves through a system as well as provide accurate radiogenic strontium isotope amount ratios.
