description: Umbrella species approaches are a widely used ‘short-cut’ to guide conservation planning and management. Determining how to select surrogate species is a current gap in praxis and would allow for more successful and efficient implementation of this approach. I used a systematic literature review and narrative synthesis to synthesize the published literature on 1) empirical evaluations of umbrella and extended- umbrella species effectiveness in terrestrial ecosystems; and 2) selection frameworks for these surrogates. In phase 1, I found that there are no generalizable criteria to identify effective umbrella species and instead identified four principles of an effective umbrella species. These are representativeness, applicability, practicality, and persistence. In phase 2, I synthesized existing selection frameworks and recommend a twelve-step process for selecting and using umbrella species in conservation planning. I conclude with six recommendations for the identification and selection of umbrella species for systematic conservation planning in terrestrial landscapes.

description: The conductance of a two-dimensional electron gas at the transition from one quantum Hall plateau to the next has sample-specific fluctuations as a function of magnetic field and Fermi energy. Here we identify a universal feature of these mesoscopic fluctuations in a Corbino geometry: The amplitude of the magnetoconductance oscillations has an e^2/h resonance in the transition region, signaling a change in the topological quantum number of the insulating bulk. This resonance provides a signed scaling variable for the critical exponent of the phase transition (distinct from existing positive definite scaling variables).

description: This thesis explores the ability of Victorian-era women to demonstrate agency in the colonial setting. The subjects of this study are Frances Simpson, Isobel Finlayson, and Letitia Hargrave, all upper-middle class European women who married fur traders of the Hudson’s Bay Company in the first half of the nineteenth century and relocated with their husbands to Rupert’s Land. While traveling to, and living in the fur trade, these women recorded their experiences and actions in the form of travel journals and letters, demonstrating how they purposefully and deliberately upheld the expectations placed upon them to be respectable, domestic, feminine women. This thesis argues that by acting in ways expected of them as Victorian-era women, Simpson, Finlayson, and Hargrave found the ability to display agency and negotiate their physical and social spaces in the fur trade.

Power Amplifier Behavioral Modeling Algorithms for Digital/Hybrid Predistortion in Software Defined Transmitters

subject: Polynomial Functions

description: Power amplifier (PA) is a vital component of transmission system and effect of PA nonlinearity and memory effects are generally investigated in system level analysis of communication systems. Among time and frequency domain approaches, time domain behavioral modeling is more popular as it also considers memory effect and it finds useful application as inverse modeling for digital predistorter to enhance the signal quality. Among many models, Memory polynomial (MP) model is still considered as most simple and effective parametric model as it provides best modeling performance with less complexity. This thesis investigates two models, which aim to improve stability and accuracy of memory polynomial model. The proposed Pseudo Zernike Memory polynomial (PZMP) model is modified version of the Zernike polynomial function, which provides more robust performance in terms of better condition number and dispersion coefficients for PA behavioral modelling, with respect to previously proposed models such as orthogonal memory polynomial (OMP) and MP model. It provides approximately, i) . 75% and 50% improvement in terms of dispersion coefficients (in dB) over MP model and OMP model respectively; ii). 61% and 15% improvement in terms of condition number (in dB) over MP model and OMP model respectively. The other model takes advantage of recursive property of Rational Polynomial (RP), which is closer to the physical analogy of PA. The proposed model retrieves data in two steps to maintain causality of the system. The proposed two-step-rational polynomial model improves modeling performance in terms of in-band and out-of-band performance and provides far better modeling as compared to memory polynomial model. This thesis also includes the study of hydrid digital predistortion (DPD) technique for complete RF-in and RF-out system. The system is implemented in Field-Programmable Gate (FPGA) using Look-Up Tables (LUT). The compensation of the I-Q (Inphase-Quadrature phase) imbalance in the setup is further studied for such system.

description: Deliverable 3.4 “Spatial scenarios for urban neighbourhoods” marks the culmination of the research phase of Work Package 3 and the commencement of the next demonstration phase. Within Work package 3 (WP3), tasks 3.2 to 3.9 have contributed to Deliverable 3.4, via the stages of the four milestones detailed in Section 3 of this report. Work Package 3 concludes with Milestone 18, an inventory of demonstration sites in the partner cities where transition strategies emerging from the research work in Work Package 3 will be trialled in Task 3.9. Impacts and results of pilot actions on demonstration sites will be measured in Task 3.10, which will act as the link between the output of Work Package 3 and Work Package 7 “Integrated Transition Strategies”. Key high-level findings and conclusions are summarised as follows: Urban resilience precipitates a paradigm shift from command and control processes to adaptive and flexible approaches that recognise that change is the only constant and respects that citizens have knowledge of systems and their own actions. Urban resilience is not a new or abstract idea. There are examples of urban resilience in practice existing within the TURAS partner cities and regions, although the language of resilience thinking may not be referenced. Urban resilience promotes the use of systems thinking in relation to cities, highlighting that all systems are interconnected and interdependent, and emphasising the import of a synoptic view and layering of datasets in GIS in order to make connections and identify opportunities and vulnerabilities. Urban resilience requires the active engagement of citizens with their place and one another in order to build awareness and participation in effecting change. Urban resilience is operationalised through a continuous process of learning, adapting and adjusting generally referred to as adaptive co-management.

description: Vibrational spectroscopy is the most effective, efficient and informative method of structural analysis of amorphous materials with silica matrix and, therefore, an indispensable tool for examining silicon oxycarbide-based amorphous materials (SiOC). The subject of this work is a description of the modification process of SiOC glasses with phosphate ions based on the structural examination including mainly Infrared and Raman Spectroscopy. They were obtained as polymer-derived ceramics based on ladder-like silsesquioxanes synthesised via the sol-gel method. With the high phosphate's volatility, it was decided to introduce the co-doping ions to create [AlPO4] and [BPO4] stable structural units. As a result, several samples from the SiPOC, SiPAlOC and SiPBOC systems were obtained with various quantities of the modifiers. All samples underwent a detailed structural evaluation of both polymer precursors and ceramics after high-temperature treatment with Fourier-transformed infrared spectroscopy (FTIR), Raman spectroscopy, X-ray diffraction (XRD) and magic angle spinning nuclear magnetic resonance (MAS-NMR). Obtained results proved the efficient preparation of desired materials that exhibit structural parameters similar to the unmodified one. They were X-ray-amorphous with no phase separation and crystallisation. Spectroscopic measurements confirmed the presence of the crucial Si-C bond and how modifying ions are incorporated into the SiOC network. It was also possible to characterise the turbostratic free carbon phase. The modification was aimed to improve the bioperformance of the materials in the context of their future application as bioactive coatings on metallic implants.

description: Speech recognition technology, which allows for the conversion of speech to text, is commonly used with individuals who struggle with writing due to cognitive, physical, or sensory issues. While there is initial support for the positive impact of speech recognition technology on specific writing outcomes (e.g., skilled writing), limited attention has been given to examining the cognitive mechanisms by which it exerts influence. One possible avenue to consider is the link between speech recognition technology and student cognitive engagement, defined as an investment in the work of learning. With evidence to suggest that certain technology use increases student engagement (e.g., interactive whiteboards, writing pads), it is possible that the use of speech recognition technology helps students to become more cognitively invested in their writing. Findings from this case study identify: (a) the extent to which students utilizing speech recognition technology are cognitively engaged in their writing; (b) necessary conditions to elicit cognitive engagement; and (c) the impact of speech recognition technology on student writing. Comparison is made between students identified as engaged and non-engaged in the writing task, with examination given to possible differences in the learning environments and student and teacher perceptions toward the use of speech recognition technology. This study provides insight into important factors to consider when using speech recognition technology in order to maximize the impact of this technology on student learning.

description: Rhizobiophages are the group of bacteriophages that infect rhizobia. The rhizobia constitute a bacterial group that includes members of several different genera and are capable of nodulating legume plant roots, and providing a source of fixed nitrogen for the plant. Rhizobiophages can play a vital role in the Rhizobium-legume symbiosis by altering the population dynamics of the rhizobia present in the rhizosphere, which can be used in agriculture to improve the efficacy of commercial Rhizobium inoculants and mitigate the Rhizobium competition problem. As a prerequisite for the application of such technology, a thorough understanding of rhizobiophage biology is required. Isolation of rhizobiophages from soil samples obtained from Alberta, Saskatchewan, Ontario and British Columbia was performed using several different strains of rhizobia as trapping hosts. The isolated phages were characterized using host range, transmission electron microscopy, protein profiles and genomic characterization. All phage isolates were characterized as tailed phages belonging to the Order Caudovirales, while further classification allowed us to place them in families Siphoviridae, Myoviridae and Podoviridae. Depending on the host range, morphotype and trapping host, several phages were selected and detailed genome characterization was performed using whole genome sequencing. Five rhizobiophage genomes were sequenced to finished state (vB_RleM_P10VF, vB_RglS_P106B, vB_RleM_PPF1, vB_MloP_Lo5R7ANS, and vB_MloP_Cp1R7ANS-C2) and annotated. The complete genome sequences of vB_RglS_P106B (KF977490), vB_RleM_PPF1 (KJ746502), vB_RleM_P10VF (KM199770) and vB_MloP_Lo5R7ANS (KM199771) are publically available at the database of National Center of Biological Information (NCBI). The genome of vB_MloP_Cp1R7ANS-C2 will be submitted to the NCBI in the near future. The integration of temperate phage vB_RleM_PPF1 into its bacterial host R. leguminosarum F1 was also studied. The site-specific recombination system of the phage targets an integration site that lies within a putative tRNA-Pro (CGG) gene in R. leguminosarum F1. Upon integration, the phage is capable of restoring the disrupted tRNA gene, owing to the 50 bp homologous sequence (att core region) it shares with its rhizobial host. To develop a phage-based inoculant technology, the phages of Rhizobium leguminosarum with broadest possible host range were selected and tested in nodulation competition assays. The presence of phages altered the nodule occupancy by phage-sensitive and phage-resistant strains of rhizobia, increasing the efficacy of nodulation by phageresistant rhizobia under controlled environmental conditions.

description: The extraction of bitumen in the Alberta oil sands results in large volumes of oil sands process-affected water (OSPW). OSPW contains an acid extractable organic (AEO) fraction that consists of numerous compounds, including naphthenic acids (NAs). This research was aimed at a functional genomic characterization of the model plant Arabidopsis thaliana (Arabidopsis) in response to OSPW, AEO, and NAs. From this research, insight was gained into the phenotypic response of Arabidopsis to OSPW, AEO, and NAs in terms of germination and early seedling development. A microarray experiment illustrated how Arabidopsis responds to AEO at the transcriptome level, and provided insight into toxicity, possible degradation pathways, and mechanisms for dealing with the stress. In addition, a large population of plants with enhanced expression of individual genes was screened for growth on model/surrogate NAs to give insight into genes that may be involved in NA tolerance, sequestration, or degradation. This research provides a framework for future work on biosensing, phytoremediation, and metabolic pathways involved in degradation/sequestration of toxic organic acids in OSPW.

description: Neural spike trains, which are sequences of very brief jumps in voltage across the cell membrane, were one of the motivating applications for the development of point process methodology. Early work required the assumption of stationarity, but contemporary experiments often use time-varying stimuli and produce time-varying neural responses. More recently, many statistical methods have been developed for nonstationary neural point process data. There has also been much interest in identifying synchrony, meaning events across two or more neurons that are nearly simultaneous at the time scale of the recordings. A natural statistical approach is to discretize time, using short time bins, and to introduce loglinear models for dependency among neurons, but previous use of loglinear modeling technology has assumed stationarity. We introduce a succinct yet powerful class of time-varying loglinear models by (a) allowing individual-neuron effects (main effects) to involve time-varying intensities; (b) also allowing the individual-neuron effects to involve autocovariation effects (history effects) due to past spiking, (c) assuming excess synchrony effects (interaction effects) do not depend on history, and (d) assuming all effects vary smoothly across time.

description: 4th Generation high-temperature gas-cooled nuclear reactors (HTGR) are regarded as possible sources of industrial heat in Poland and Europe, allowing for a substantial reduction of the dependency on gas and coal import. It is mainly due to their safety of use, reliability and economy in a current energetic crisis. In this work, graphite, as a primary construction material and neutron moderator in HTGR, was evaluated before and after ion irradiation since its properties depend on the material's structure and purity. Commercial graphite materials (IG-110, NBG-17) and the laboratory's in-home material were chosen for the exemplary samples. The structural damage in HTGR was simulated with energetic Ar+ and He+ ions with fluencies from 1E12 to 2E17 ion/cm2. Raman imaging was chosen to assess radiation damage build-up: the crystallites' evolution, occurrence and types of defects. The recorded evolution showed stronger disordering of the material with heavier Ar+ ions than with He+.

description: We investigate theoretically the feasibility of generation and amplification of terahertz radiation in aligned achiral carbon nanotubes (zigzag and armchair) in comparison with a superlattice in the presence of a constant (dc) and high-frequency (ac) electric fields. The electric current density expression is derived using the semiclassical Boltzmann transport equation with a constant relaxation time with the electric field applied along the nanotube axis. Our analysis on the current density versus electric field characteristics demonstrates negative differential conductivity at high frequency as well as photon assisted peaks. The characteristic peaks are about an order of magnitude styronger in the carbon nanotubes compared to superlattice. These strong phenomena in carbon nanotubes can be used to obtain domainless amplification of terahertz radiation in carbon nanotubes at room temperature.

Examining the Effect of Warning Instructions in the Interview

description: Employment interviews are often used in making hiring decisions, and as such, interview accuracy is critical. One obstacle that organizations face is that as an interviewer is trying to evaluate an interviewee, the interviewee is simultaneously trying to present him or herself as the best candidate through the use of Impression Management (IM). This study investigates the novel application of three different warning instructions as a method to reduce IM usage in the interview. Results indicated that warning instructions do not appear to influence IM tactic usage or applicant reactions in the interview. Supplemental analyses revealed significant main and moderating effects of an individual difference, Honesty-Humility. Though warnings did not have a direct effect on IM tactic usage, they appear to influence cognitions related to response distortion. Additionally, as Honesty-Humility was positively related to the use of extensive IM tactics, screening procedures may be needed. Keywords: warning instructions, impression management, employment interview, honesty-humility, selection
Quantifying Selection and Diversity in Viruses by Entropy Methods, with Application to the Hemagglutinin of H3N2 Influenza

description: Many viruses evolve rapidly. For example, hemagglutinin of the H3N2 influenza A virus evolves to escape antibody binding. This evolution of the H3N2 virus means that people who have previously been exposed to an influenza strain may be infected by a newly emerged virus. In this paper, we use Shannon entropy and relative entropy to measure the diversity and selection pressure by antibody in each amino acid site of H3 hemagglutinin between the 1992-1993 season and the 2009-2010 season. Shannon entropy and relative entropy are two independent state variables that we use to characterize H3N2 evolution. The entropy method estimates future H3N2 evolution and migration using currently available H3 hemagglutinin sequences. First, we show that the rate of evolution increases with the virus diversity in the current season. The Shannon entropy of the sequence in the current season predicts relative entropy between sequences in the current season and those in the next season. Second, a global migration pattern of H3N2 is assembled by comparing the relative entropy flows of sequences sampled in China, Japan, the USA, and Europe. We verify this entropy method by describing two aspects of historical H3N2 evolution. First, we identify 54 amino acid sites in hemagglutinin that have evolved in the past to evade the immune system. Second, the entropy method shows that epitopes A and B in the top of hemagglutinin evolve most vigorously to escape antibody binding. Our work provides a novel entropy-based method to predict and quantify future H3N2 evolution and to describe the evolutionary history of H3N2.

description: We report the electronic properties of R4PtAl (R = Ho, and Er), which contains 3 sites for R, by the measurements of magnetization (ac and dc), heat-capacity, transport, and magnetoresistance (MR). Dc magnetization data reveal antiferromagnetic order below 19 K and 12 K in Ho and Er compounds, respectively. Additional features observed at lower temperatures (12 K for Ho4PtAl and 5 K for Er4PtAl) are akin to cluster spin-glass phase. Resistivity data exhibit a weak minimum at a temperature marginally higher than their respective Néel temperature (T_N) which is unusual for such rare-earths with well localized 4f states. Isothermal magnetization and magnetoresistance data well below T_N exhibit signatures of a subtle field-induced magnetic transition for a small magnetic field (less than 10 kOe). Notably, the isothermal entropy change at T_N has the largest peak value within this rare-earth family; for a field change from zero to 50 kOe, the entropy change is about 14.5 J/kg K (Ho4PtAl) and 21.5 J/kg K (Er4PtAl) suggesting a role of anisotropy of 4f orbital in determining this large value. The results provide some clues for the advancement of the field of magnetocaloric effect. The magnetocaloric property of Er4PtAl is nonhysteretic meeting a challenge to find materials with reversible magnetocaloric effect.

description: Lysorophia is a poorly-understood group of fossil tetrapods known from the Late Carboniferous and Early Permian of North America. Some prior workers have noted similarities between lysorophians and modern amphibians, suggesting that lissamphibians may have evolved from lysorophian-like ancestors. I used high resolution x-ray micro-computed tomography (HR-XCT) to study skulls of the lysorophian Brachydectes newberryi from the Early Permian of Kansas and Nebraska, USA. I present a detailed description of the skeletal morphology of these skulls, including fine structure of the braincase. With reference to the skeletal morphology described here, I present a list of new, phylogenetically-informative characters from the braincase and incorporate these into phylogenetic analysis of early tetrapods. Lysorophians are found to be microsaurs, a diverse group of early tetrapods. The data presented here suggest that lysorophians and microsaurs may be early reptiles and thus not relevant to the discussion of lissamphibian origins.

description: Recently, polarons in the Peyrard-Bishop-Holstein model under DC electric fields were established to perform Bloch oscillations, provided the charge-lattice coupling is not large. In this work, we study this model when the charge is subjected to an applied field with both DC and AC components. Similarly to what happens in the rigid lattice, we find that the carrier undergoes a directed motion or coherent oscillations when the AC field is resonant or detuned with respect to the Bloch frequency, respectively. The electric density current and its Fourier spectrum are also studied to reveal the frequencies involved in the polaron dynamics.

description: We have investigated for the first time the magnetic behaviour of an intermetallic compound, Dy4RhAl, crystallizing in Gd4RhIn type cubic structure containing 3 sites for rare-earth (R), by several bulk measurements down to 1.8 K. This work is motivated by the fact that the isostructural Dy compound in the R4PtAl family surprisingly orders ferromagnetically unlike other members of this series, which order antiferromagnetically. The results reveal that the title compound undergoes antiferromagnetic order at about 18 K, similar to other heavy R members of R4RhAl family, unlike its Pt counterpart, indicating a subtle difference in the role of conduction electrons to decide magnetism of these compounds. Besides, spin-glass features coexisting with antiferromagnetic order could be observed, which could mean cluster antiferromagnetism. The electrical resistivity and magnetoresistance behaviours in the magnetically ordered state are typical of magnetic materials exhibiting antiferromagnetic gap. Features attributable to spin-reorientation as a function of temperature and magnetic field can be seen in the magnetization data.

description: A dairy cow at its first appearance looks extremely angular and carries no surplus flesh and it should have extraordinary development of udder and milk vein. The barrel (body) development should be marked in proportion to the size of the animal.
The dairy conformation signifies that appearance which indicates a tendency to produce milk rather than body fat. The body of the dairy cow should be angular in shape as viewed from the front, the side and over the top or withers.
The angularity of the body is referred as the three wedges. The top and bottom lines, if extended (imaginary) will be in front of the head forming the first wedge. When viewed from the front, the two lines over the shoulder should meet at withers. The third wedge is the line drawn from the hook bones to the withers, with the apex at the withers.
in addition to the three wedges there should not be any excess fleshing and coarseness and all part should have clean cut. The back, hook and pin bones should be prominent and free from coarseness.
A Novel Approach to Employee Recruitment: Gamification

description: Gamification is the use of game-design in a non-game context to attract, engage and elicit desired behaviors. Recently, a number of organizations have employed the use of gamification for the purpose of employee recruitment. Results of these gamified recruitment processes are purportedly positive, although no empirical studies to date have been conducted to determine their effectiveness. This thesis was designed to provide an objective and empirical analysis of the efficacy of gamified recruitment procedures compared to traditional recruitment practices. Results indicated that traditional recruitment processes were more effective in changing participant attitudes towards organizations than the gamified processes. However, although traditional recruitment practices engendered more positive attitudes towards companies, both recruitment practices generated a similar amount of interest in terms of applying for jobs at the respective company. Implications of these findings are discussed.

description: It has been shown that very light or even massless neutralinos are consistent with all current experiments, given non-universal gaugino masses. Furthermore, a very light neutralino is consistent with astrophysical bounds from supernovæ and cosmological bounds on dark matter. Here we study the cosmological constraints on this scenario from Big Bang nucleosynthesis taking gravitinos into account and find that a very light neutralino is even favoured by current observations.

description: MHD wave propagation inside the Sun's atmosphere is closely related to the magnetic field topology. For example, magnetic fields are able to lower the cutoff frequency for acoustic waves thus allowing waves which would otherwise be trapped below the photosphere to propagate into the upper atmosphere. Another example is that MHD waves can be transmitted or converted into other forms of waves at altitudes where the sound speed equals the Alfvén speed. We take advantage of the large field-of-view provided by the IBIS experiment to study the wave propagation at two heights in the solar atmosphere, as sampled by the photospheric Fe 617.3 nm spectral line and the chromospheric Ca 854.2 nm spectral line, and its relationship to the local magnetic field. Among other things, we find substantial leakage of waves with 5-minute periods in the chromosphere at the edges of a pore and in the diffused magnetic field surrounding it. By using spectro-polarimetric inversions of Hinode SOT/SP data, we also find a relationship between the photospheric power spectrum and the magnetic field inclination angle; in particular, well-defined transmission peaks around 25\degree for 5 minutes waves and around 15\degree for 3 minutes waves. We propose a very simple model based upon wave transmission theory to explain this behavior. Finally, an analysis of both the power spectra and chromospheric amplification spectra suggests the presence of longitudinal acoustic waves along the magnetic field lines.

description: This dissertation describes the discovery and development of the concept of the particle called neutrino, in a perspective of the philosophy of science of Imre Lakatos, developing a historiographic and epistemological analysis about the scientific practice, which culminated with the formulation of the neutrino particle, as well as later developments. In this sense, the work makes a rational reconstruction about the research program that the neutrino formulation and discovery participates, as well as the law of conservation of energy can be understood as a fundamental part of the methodological assumptions of such program.
A filamentation instability for streaming cosmic-rays

description: We demonstrate that cosmic rays form filamentary structures in the precursors of supernova remnant shocks due to their self-generated magnetic fields. The cosmic-ray filamentation results in the growth of a long wavelength instability, and naturally couples the rapid non-linear amplification on small scales to larger length scales. Hybrid magnetohydrodynamics--particle simulations are performed to confirm the effect. The resulting large scale magnetic field may facilitate the scattering of high energy cosmic rays as required to accelerate protons beyond the knee in the cosmic-ray spectrum at supernova remnant shocks. Filamentation far upstream of the shock may also assist in the escape of cosmic rays from the accelerator.

Characterizing Susceptibility Weighted MRI in the Experimental Autoimmune Encephalomyelitis Mouse Model of Multiple Sclerosis

description: Susceptibility-based magnetic resonance imaging (MRI) methods have been used in multiple sclerosis (MS) patients for lesion detection, visualization of the venous vasculature and to show abnormal iron accumulation in the deep grey matter structures of the brain. The overarching goal of this thesis was to characterize one of the susceptibility-based MRI methods, susceptibility weighted imaging (SWI), in the experimental autoimmune encephalomyelitis (EAE) mouse model of MS. First, we investigated if SWI could detect lesions (or hypointensities) in the lumbar spinal cords and cerebella of EAE mice. We found that SWI hypointensities were present in a region-specific manner in the CNS of EAE mice, where most of these lesions were attributed to deoxyhemoglobin and a smaller number were due to parenchymal iron deposition. Next, we validated a method to identify deoxyhemoglobin-based SWI hypointensities in vivo which entailed combining SWI with hyperoxygenation. Following this, we sought to investigate when SWI hypointensities appear during the EAE disease course and how they change over the course of the disease. This was studied by carrying out serial SWI in vivo in naïve mice and mice immunized for EAE. Here, we found that SWI hypointensities are prominent before signs of motor dysfunction in EAE mice. SWI hypointensities were also observed to evolve over the disease course. Of note, the number of SWI hypointensities was always at a maximum before or at the same time as maximum motor dysfunction. Unlike EAE mice, the number of SWI hypointensities remained stable through all imaging time points in naïve mice, suggesting that SWI hypointensities are linked to EAE pathophysiology. Lastly we used SWI to assess treatment response to an anti-inflammatory treatment (dexamethasone) in EAE mice. This was carried out under the premise that SWI hypointensities may be linked to inflammation, so reducing inflammation could reduce the number of SWI hypointensities present. Our preliminary data suggest that SWI may be able to act as a surrogate marker of inflammation. Overall, findings from this thesis support the use of SWI in future studies in the EAE model to investigate the venous vasculature and parenchymal iron deposition.
