description: Alpine karst aquifers serve as vital sources of groundwater and play an important role in supporting local ecosystems. This study investigated the hydrogeology of the Watridge Karst Spring in the southern Canadian Rocky Mountains, an example of a snowmelt-dominated alpine karst aquifer with rapid, long-distance flow. An annual water budget suggested a catchment area of around 20 km2 and dye tracer tests revealed groundwater velocities of up to 0.14 m s−1. The aquifer has a hierarchical conduit structure with underflow-overflow dynamics, and year-round discharge is sustained by fracture flow. This dual flow network allows the aquifer to behave similarly to a surface stream over long distances, but also as a large groundwater reservoir. An innovative approach was introduced to estimate groundwater response times to snowmelt in alpine karst springs using diurnal discharge and electrical conductivity fluctuations, expanding upon previous methods using spectral analysis and cross-correlation. A continuous record of response times was obtained throughout the entire snowmelt seasons of 2020 and 2021. These showed that dilution response time steadily increased alongside decreasing hydraulic head, while celerity remained constant. Geologically analogous karst catchments in the Rocky Mountains hold the potential for storing mountain water, which warrants further studies of groundwater flow in these systems. Climate change may impact the hydrological functioning of alpine karst springs, highlighting the importance of understanding these systems for sustainable water resource management.

description: We explore string/M-theory constructions of holographic theories with Lifshitz scaling exponent $z$ and hyperscaling violation exponent $θ$, finding a range of $z,θ$-values. Some of these arise as effective metrics from dimensional reduction of certain kinds of null deformations of $AdS$ spacetimes appearing in the near horizon geometries of extremal D3-, M2- and M5-brane theories. The $AdS_5$ solution in particular gives rise to $θ=1$ in $d=2$ (boundary) space dimensions. Other solutions arise as the IIA D2- and D4-brane solutions with appropriate null deformations, and we discuss the phase structure of these systems.

description: While many studies assess risk management in a private sector context, public sector risk management and particularly with a focus on German municipalities is lagging behind. One main question in this regard is what factors drive the implementation of risk management in German municipalities. This article addresses that research gap by means of a structural equation model. The results evidence that the stage of risk management implementation is positively related to six factors and the implementation stage of risk management is positively related to the quality of risk management. The organisation size shows a moderating effect on the results.

The refinement of an online, theory-based intervention to decrease COVID-19 vaccination hesitancy in Canadian adults: Phase I of the iPROTECT Study
Creators: name: Seidel, Sydney
Publisher: name: Arts
Year: 2023
Subjects: subject: COVID-19 vaccination
subject: vaccination hesitancy
subject: Psychology--Clinical

description: Background: Approximately 6.9 million deaths due to the coronavirus disease of 2019 (COVID-19) have occurred worldwide. While around 86% of Canadians are fully vaccinated against COVID-19, only 55% have received a booster dose. Current public health strategies to address COVID-19 vaccine hesitancy are inconsistent with health behaviour change theory. Self- determination theory (SDT) is an evidence-based framework which seeks to enhance individual motivation for behaviour change. The purpose of the present study is to refine and evaluate the preliminary effects of an online intervention grounded in SDT to address COVID-19 vaccination hesitancy in Canadian adults, using multi-phasic, pilot mixed methods studies. The present study is divided into two phases (Phases I a and b). Methods: Phase Ia: A purposive sample of 19 Canadian adults (18+) were recruited to participate in a one-on-one- semi-structured interview guided by the Think Aloud method to provide their perspectives on the intervention. Qualitative data was analyzed using Thematic Analysis. Phase Ib: A purposive sample of 70 Canadian adults completed the intervention to assess whether it produced indications of a preliminary clinical signal (i.e., defined by at least 40% of participants increasing their likelihood of receiving an additional COVID-19 vaccine one-week post-intervention). Acceptability and usability measures were collected as secondary outcomes. Results: Phase Ia revealed 4 overarching themes: (1) Normalization video is neutral and emphasizes agency, (2) Intervention language is impartial and accessible, (3) User experiences with the intervention are acceptable, and (4) Feedback for intervention refinement. Phase Ib demonstrated that a preliminary clinical signal was not achieved (20% of participants increased the likelihood at one-week follow-up). However, acceptability (uMARS Total App Quality = 4.38 out of 5) and usability (Total SUS = 80.72 out of 100) measures revealed high participant ratings. Conclusion: This preliminary work provides support for high levels of intervention usability and acceptability. Additional testing to assess for a clinical signal threshold should be conducted prior to progression toward proof-of-concept pilot testing.

description: Anecdotal reports within the Caribbean track and field fraternity have revealed that there is a high level of athlete dropout from competitive sport at the junior-elite level, and a poor transition to senior-elite status. Consequently, this qualitative investigation explored the key motives that may have contributed toward the unsuccessful transitions and ensuing dropout of Caribbean track and field athletes during the junior to senior transition period. Eleven former junior-elite track and field athletes (four males, seven females; Mage = 29, SD ± 4.2 years) from four English-speaking Caribbean islands participated in semi-structured interviews. Following an inductive and deductive thematic analysis, four higher order themes were identified: (1) “there's not enough support”; (2) “felt pressure to make sure I committed”; (3) “it's always competitive here”; and (4) “battle with the injuries.” For these former junior-elite Caribbean athletes, the decision on whether to continue within the sport was influenced by a combination of factors, although inadequate financial and organizational support had the most bearing on athletes' decision to drop out during the crucial transition years. Implications for consideration by key stakeholders and policymakers within the region are discussed.

Investigating the effect of dynamic culture and lactate on colony formation of human induced pluripotent stem cells (hiPSCs)

description: Research into stem cell treatments has led to the ability to reprogram somatic cells in the body, like skin cells and bloods cells, to behave like stem cells, and have pluripotent characteristics, ability to self-renew and develop into almost any cell type or tissue. These reprogrammed cells, referred to as human induced pluripotent stem cells (hiPSCs), have broad applications in cell therapy, drug screening, and disease modelling. Unlike traditional pluripotent cells, these cells are more accessible, avoid ethical concerns, and can be used for autologous therapies. Various methods of reprogramming somatic cells are available but come with challenges of virus integration into the genome, low reprogramming efficiency, and long transition from cultivation to large-scale manufacturing. The proposed research addresses this by combining two innovative approaches for improved somatic cell reprogramming: 1. transient exposure to lactate, and 2. dynamic culture environment. The generation of hiPSCs is highly dependent on a metabolic shift from oxidative phosphorylation (OXPHOS) to glycolysis and lactate has shown to facilitate this metabolic shift thereby potentially increasing reprogramming efficiency. The dynamic environment also plays a role in reprogramming and the subsequent physiology which allows for great cell expansion, heterogeneity and scale-up. This study first outlines the isolated effects of a dynamic system and transient lactate exposure on the reprogramming process as well as the optimization of these conditions. The two approaches were then integrated with findings suggesting that the independent conditions outperformed the tandem. Further phenotype and functional testing post reprogramming is required, however the examined conditions show promise in increasing reprogramming efficiency, reducing time of reprogramming process and improving translation to a bioprocess.

description: The effect of chaotic bath dynamics on the decoherence of a quantum system is examined for the vibrational degrees of freedom of a diatomic molecule in a realistic, constant temperature collisional bath. As an example, the specific case of I$_2$ in liquid xenon is examined as a function of temperature, and the results compared with an integrable xenon bath. A crossover in behavior is found: the integrable bath induces more decoherence at low bath temperatures than does the chaotic bath, whereas the opposite is the case at the higher bath temperatures. These results, verifying a conjecture due to Wilkie, shed light on the differing views of the effect of chaotic dynamics on system decoherence.

Dynamical Flow Characteristics in Response to a Maneuver in the L1 or L2 Earth-Moon Region

description: National security concerns regarding cislunar space have become more prominent due to the anticipated increase in cislunar activity. Predictability is one of these concerns. Cislunar motion is difficult to predict because it is chaotic. The chaotic nature of cislunar motion is pronounced near the L1 and L2 Lagrange points. For this reason, among others, it is likely that a red actor (an antagonist) would have its cislunar spacecraft perform a maneuver in one of the aforementioned vicinities to reach some cislunar point of interest. This realization unveils the need to ascertain some degree of predictability in the motion resulting from a maneuver performed in the L1 or L2 region. To investigate said motion, impulsive maneuvers are employed on the L1 and L2 Lagrange points and on L1 and L2 Lyapunov orbits in the model that is the circular restricted three-body problem. The behavior of the resultant trajectories is analyzed to understand how the magnitude and direction of a maneuver in said regions affect the behavior of the resultant trajectory. It is found that the direction of such maneuvers is particularly influential with respect to said behavior. Regarding both the L1 and L2 regions, certain maneuver directions yield certain behaviors in the resultant trajectory over a wide range of maneuver magnitudes. This understanding is informative to cislunar mission design.

Alternate history - alternate memory : counterfactual literature in the context of German normalization
Creators: name: Schenkel, Guido
Publisher: name: University of British Columbia
Year: 2012

description: This dissertation examines a variety of Alternate Histories of the Third Reich from the perspective of memory theory. The term ‘Alternate History’ describes a genre of literature that presents fictional accounts of historical developments which deviate from the known course of history. These allohistorical narratives are inherently presentist, meaning that their central question of “What If?” can harness the repertoire of collective memory in order to act as both a reflection of and a commentary on contemporary social and political conditions. Moreover, Alternate Histories can act as a form of counter-memory insofar as the counterfactual mode can be used to highlight marginalized historical events. This study investigates a specific manifestation of this process. Contrasted with American and British examples, the primary focus is the analysis of the discursive functions of German-language counterfactual literature in the context of German normalization. The category of normalization connects a variety of commemorative trends in postwar Germany aimed at overcoming the legacy of National Socialism and re-formulating a positive German national identity. The central hypothesis is that Alternate Histories can perform a unique task in this particular discursive setting. In the context of German normalization, counterfactual stories of the history of the Third Reich are capable of functioning as alternate memories, meaning that they effectively replace the memory of real events with fantasies that are better suited to serve as exculpatory narratives for the German collective. To develop the theoretical framework for this new category, the dissertation delineates and contrasts pertinent theories of both collective memory and counter-memory and harnesses the scholarly findings of these fields to expand existing critical understandings of the genre of Alternate History. The combination of this sociological approach with the methodology of literary studies is applied in a close reading to an exemplary selection of Alternate Histories, grouped into three themes which correspond closely to prominent narratives of German collective memory: The universalization of National Socialism, the motif of the ‘good German,’ and the myth of German victimization. This approach demonstrates in detail the narrative strategies that constitute alternate memory in the context of German normalization.

description: We study the production of bound cascade hypernuclei via the (K-,K+) reaction on 12C and 28Si targets within a covariant effective Lagrangian model, employing the cascade bound state spinors derived from the latest quark-meson coupling model as well as Dirac single particle wave functions. The K+-cascade production vertex is described by excitation, propagation and decay of Lambda and Sigma resonance states in the initial collision of a K- meson with a target proton in the incident channel. The parameters of the resonance vertices are fixed by describing the available data on total and differential cross sections for the cascade production in elementary (K-,K+) reaction. We find that both the elementary and hypernuclear production cross sections are dominated by the contributions from the Lambda(1520) intermediate resonant state. The 0 degree differential cross sections for the formation of simple s-state cascade particle-hole states peak at a beam momentum around 1.0 GeV/c, with a value in excess of 1 mub.

description: In favourable cases the low energy dynamics of a stack of M2-branes at a toric Calabi-Yau fourfold singularity can be described by an N=2 supersymmetric Chern-Simons quiver theory, but there still does not exists an "inverse algorithm" going from the toric data of the CY_4 to the CS quiver. We make progress in that direction by deriving CS quiver theories for M2-branes probing cones over a large class of geometries Ypq(B_4), which are S^3/Z_p bundles over toric Fano varieties B_4. We rely on the type IIA understanding of CS quivers, giving a firm string theory footing to our CS theories. In particular we give a derivation of some previously conjectured CS quivers in the case B_4= CP^1*CP^1, as field theories dual to M-theory backgrounds with nontrivial torsion G_4 fluxes.

description: Geospatial data analysis often requires the computing of a distance transform (DT) for a given vector feature. For instance, in wildfire management, it is helpful to find the distance of all points in an area from the wildfire’s boundary. Computing a distance transform on traditional Geographic Information Systems (GIS) is usually adopted from image processing methods, albeit prone to distortion resulting from flat maps. Discrete Global Grid Systems (DGGS) are relatively new low-distortion globe-based GIS that discretize the Earth into highly regular cells using multiresolution grids. In this thesis, we introduce an efficient DT algorithm for DGGS. Our novel algorithm heavily exploits the hierarchy of a DGGS and its mathematical properties and applies to many different DGGSs. We evaluate our method by comparing its distortion with the DT methods used in traditional GIS and its speed with the application of general 3D mesh DT algorithms on the DGGS grid. We demonstrate that our method is efficient and has lower distortion. To evaluate our DT algorithm further, we have used a real-world case study of selecting soil test points within agricultural fields. Multiple criteria including the distance of soil test points to different features should be considered to select representative points in a field. We show that DT can help to automate the process of selecting test points, by allowing us to efficiently calculate objectives for a representative test point. DT also allows for efficient calculation of buffers from certain features such as farm headlands and underground pipelines, to avoid certain regions when selecting the test points.

description: Adaptive MCMC is advantageous over traditional MCMC due to its ability to automatically adjust its proposal distributions during the sampling process, providing improved sampling efficiency and faster convergence to the target distribution, especially in complex or high-dimensional problems. However, designing and validating the adaptive scheme cautiously is crucial to ensure algorithm validity and prevent the introduction of biases. This dissertation focuses on the use of Adaptive MCMC for deep learning, specifically addressing the mode collapse issue in Generative Adversarial Networks (GANs) and implementing Fiducial inference, and its application to Causal inference in individual treatment effect problems.
 First, GAN was recently introduced in the literature as a novel machine learning method for training generative models. However, GAN is very difficult to train due to the issue of mode collapse, i.e., lack of diversity among generated data. We figure out the reason why GAN suffers from this issue and lay out a new theoretical framework for GAN based on randomized decision rules such that the mode collapse issue can be overcome essentially. Under the new theoretical framework, the discriminator converges to a fixed point while the generator converges to a distribution at the Nash equilibrium.
 Second, Fiducial inference was generally considered as R.A. Fisher's a big blunder, but the goal he initially set, making inference for the uncertainty of model parameters on the basis of observations, has been continually pursued by many statisticians. By leveraging on advanced statistical computing techniques such as stochastic approximation Markov chain Monte Carlo, we develop a new statistical inference method, the so-called extended Fiducial inference, which achieves the initial goal of fiducial inference.
 Lastly, estimating ITE is important for decision making in various fields, particularly in health research where precision medicine is being investigated. Conditional average treatment effect (CATE) is often used for such purpose, but uncertainty quantification and explaining the variability of predicted ITE is still needed for fair decision making. We discuss using extended Fiducial inference to construct prediction intervals for ITE, and introduces a double neural net algorithm for efficient prediction and estimation of nonlinear ITE.

description: In this paper we study symmetries, Newtonoid vector fields, conservation laws, Noether's Theorem and its converse, in the framework of the $k$-symplectic formalism, using the Frölicher-Nijenhuis formalism on the space of $k^1$-velocities of the configuration manifold. For the case $k=1$, it is well known that Cartan symmetries induce and are induced by constants of motions, and these results are known as Noether's Theorem and its converse. For the case $k>1$, we provide a new proof for Noether's Theorem, which shows that, in the $k$-symplectic formalism, each Cartan symmetry induces a conservation law. We prove that, under some assumptions, the converse of Noether's Theorem is also true and we provide examples when this is not the case. We also study the relations between dynamical symmetries, Newtonoid vector fields, Cartan symmetries and conservation laws, showing when one of them will imply the others. We use several examples of partial differential equations to illustrate when these concepts are related and when they are not.

description: The purpose of this research was to develop an understanding of the perspectives of a group of teachers who engaged in regular physical activity and the subsequent impacts on their wellbeing. Specifically, the research design was a qualitative case study methodology. Teacher participants were asked to engage in semi structured interviews and participant journaling. Participants were asked to reflect deeply about their experiences engaging in physical activity. The researcher then examined school division documents related to teacher wellbeing to further understand the perspectives within the environment in which these teachers worked. Increased understanding of both external and internal factors related to physical activity and relating this to a holistic understanding of wellbeing including social-emotional, spiritual, mental, and physical will contribute to the literature surrounding teacher wellbeing. The results of this study may be used by governments, along with school divisions, to consider how they can support teachers in their quest for wellbeing. In addition, it is possible the results of this study may provide inspiration for current and future teachers to consider how engaging in physical activity may contribute to their wellbeing.

description: In order to study ultracold charge-transfer processes in hybrid atom-ion traps, we have mapped out the potential energy curves and molecular parameters for several low lying states of the Rb, Yb$^+$ system. We employ both a multi-reference configuration interaction (MRCI) and a full configuration interaction (FCI) approach. Turning points, crossing points, potential minima and spectroscopic molecular constants are obtained for the lowest five molecular states. Long-range parameters, including the dispersion coefficients are estimated from our {\it ab initio} data. The separated-atom ionization potentials and atomic polarizability of the ytterbium atom ($α_d=128.4$ atomic units) are in good agreement with experiment and previous calculations. We present some dynamical calculations for (adiabatic) scattering lengths for the two lowest (Yb,Rb$^+$) channels that were carried out in our work. However, we find that the pseudo potential approximation is rather limited in validity, and only applies to nK temperatures. The adiabatic scattering lengths for both the triplet and singlet channels indicate that both are large and negative in the FCI approximation.

description: Energy transfer in the photosynthetic complex of the Green Sulfur Bacteria known as the Fenna-Matthews-Olson (FMO) complex is studied theoretically taking all three subunits (monomers) of the FMO trimer and the recently found eighth bacteriochlorophyll (BChl) molecule into account. We find that in all considered cases there is very little transfer between the monomers. Since it is believed that the eighth BChl is located near the main light harvesting antenna we look at the differences in transfer between the situation when BChl 8 is initially excited and the usually considered case when BChl 1 or 6 is initially excited. We find strong differences in the transfer dynamics, both qualitatively and quantitatively. When the excited state dynamics is initialized at site eight of the FMO complex, we see a slow exponential-like decay of the excitation. This is in contrast to the oscillations and a relatively fast transfer that occurs when only seven sites or initialization at sites 1 and 6 is considered. Additionally we show that differences in the values of the electronic transition energies found in the literature lead to a large difference in the transfer dynamics.

description: The advent of industry 4.0 has resulted in increased availability, velocity, and volume of data as well as increased data processing capabilities. There is a need to determine how best to incorporate these advancements to improve the performance of manufacturing systems. The purpose of this research is to present a solution for incorporating industry 4.0 into manufacturing systems. It will focus on how such a system would operate, how to select resources for the system, and how to configure the system. Our proposed solution is a smart manufacturing system that operates as a self-coordinating system. It utilizes a multi-agent system (MAS) approach, where individual entities within the system have autonomy to make dynamic scheduling decisions in real-time. This solution was shown to outperform alternative scheduling strategies (right shifting and dispatching priority rule) in manufacturing environments subject to uncertainty in our simulation experiments. The second phase of our research focused on system design. This phase involved developing models for two problems: (1) resource selection, and (2) layout configuration. Both models developed use simulation-based optimization. We first present a model for determining machine resources using a genetic algorithm (GA). This model yielded results comparable to an exhaustive search whilst significantly reducing the number of required experiments to find the solution. To address layout configuration, we developed a model that combines hierarchical clustering and GA. Our numerical experiments demonstrated that the hybrid layouts derived from the model result in shorter and less variable order completion times compared to alternative layout configurations. Overall, our research showed that MAS-based scheduling can outperform alternative dynamic scheduling approaches in manufacturing environments subject to uncertainty. We also show that this performance can further be improved through optimal resource selection and layout design.

description: We report an updated measurement of the CP-violating phase, $ϕ_s^{J/ψϕ}$, and the decay-width difference for the two mass eigenstates, $ΔΓ_s$, from the flavor-tagged decay $B_s^0 \rightarrow J/ψϕ$. The data sample corresponds to an integrated luminosity of 8.0 fb$^{-1}$ accumulated with the D0 detector using $p \barp$ collisions at $\sqrt{s} = 1.96$ TeV produced at the Fermilab Tevatron collider. The 68% confidence level intervals, including systematic uncertainties, are $ΔΓ_s = 0.163 +0.065 -0.064 ps^{-1}$ and $ϕ_s^{J/ψϕ} = -0.55 +0.38 -0.36$. The $p$-value for the Standard Model point is 29.8%.

On financial generosity and well-being : where, when, and how spending money on others increases happiness

description: Can money buy happiness? Recent research has shown that how people spend their money can have important consequences for their well-being. Specifically, research by Dunn, Aknin, and Norton (2008) demonstrated that spending money on others (prosocial spending) leads to higher levels of happiness than spending money on oneself (personal spending). This dissertation extends upon the work of Dunn et al. (2008) in five ways. First, Study 1 examines whether the mood benefits of prosocial spending are self-perpetuating by asking people to recall a previous personal or prosocial spending experience, report their happiness and make a future spending choice. Findings support the presence of a feedback loop; recalling a previous act of prosocial spending led to higher levels of happiness, and higher levels of happiness, in turn, predicted a willingness to engage in prosocial spending again. Second, Studies 2 - 4 test whether the relationship between prosocial spending and happiness requires positive social connection. Participants given the opportunity to spend on others by making a charitable donation (Study 2) or engaging in interpersonal spending (Studies 3 and 4) were happier when giving allowed for positive interpersonal connection with a beneficiary, but not when this connection was blocked or minimized. Third, Studies 5 and 6 examine whether perceived prosocial impact – the belief that one made a positive influence on someone else– represents another critical moderator of the emotional benefits of generous spending. Fourth, Studies 7, 8a, and 8b investigate whether the happiness benefits of prosocial spending exist outside North America and in other countries around the world. Using data from the Gallup World Poll, the relationship between prosocial spending and well-being was found to be positive in the majority of countries surveyed (Study7). Furthermore, participants in Canada and Uganda (Study 8a) and India (Study 8b) who recalled making a purchase for someone else reported higher levels of happiness than those who recalled making a purchase for themselves. Finally, Study 9 explores whether the emotional benefits of sharing one’s resources are detectable in children (< 24 months). Taken together, this research provides greater insight into the relationship between generous financial behavior and well-being.

Software maintenance

description: Software evolution plays a vital role in modern software development. As software systems become more sophisticated and involve more teams and organizations, the evolution of the code bases becomes increasingly frequent, introducing significant challenges to software maintenance and quality assurance. The challenges come from multiple aspects. On the one hand, it is essential to upgrade software components to maintain the health and functionality of code bases. On the other hand, correctly evolving software systems is a non-trivial task, as inappropriate upgrades can cause incompatibility issues. Furthermore, certain characteristics of code bases can increase the difficulty of updating software. Eliminating such characteristics is necessary to ease the maintenance and evolution activities. Our research consists of three techniques. First, we present CompCheck, an automated upgrade compatibility checking framework that generates incompatibility-revealing tests based on previous examples. Second, we introduce JUntangler, a dynamic approach for automatically untangling functionalities of Jupyter Notebooks. Third, we introduce Relancer, an automatic technique that restores the executability of broken Jupyter Notebooks by upgrading deprecated APIs. We instantiate the techniques in automated tools and evaluate them using real-world software projects. The experimental results demonstrate the effectiveness and efficiency of our techniques.

description: The study of fractional variational problems in terms of a combined fractional Caputo derivative is introduced. Necessary optimality conditions of Euler-Lagrange type for the basic, isoperimetric, and Lagrange variational problems are proved, as well as transversality and sufficient optimality conditions. This allows to obtain necessary and sufficient Pareto optimality conditions for multiobjective fractional variational problems.

description: Epilepsy is a neurological disease affecting 70 million people worldwide. For most individuals, these seizures can be controlled using medications, however nearly 1 in 3 people may need surgery to achieve seizure freedom. For this surgery to be successful, the brain region generating the seizures, which contains the critical seizure onset zone (SOZ), must be accurately identified and removed. Unfortunately, the surgical success rate is low likely due to imprecise determination of the SOZ. As a novel approach to SOZ identification, the collection of intracranial electroencephalography and functional magnetic resonance imaging (iEEG-fMRI) has been proposed as a novel method of identifying the SOZ. However, iEEG-fMRI faces the methodological challenge of artifact introduced from MR scanning which completely obscures the physiological EEG signal. Therefore, the first step towards bringing iEEG-fMRI into the clinical realm is to improve methods for extracting the physiological EEG signal from the iEEG-fMRI data. To this end, the first study in this thesis validated a set of methods aimed at removing fMRI artifact from iEEG, culminating in the creation of the first automatic iEEG pre-processing pipeline. The next step towards clinical utility for iEEG-fMRI is improving our interpretation of iEEG-fMRI results. Traditionally, only positive IED related fMRI activation maps were considered in relation to SOZ localization, and the negative response was ignored. It has been suggested that both positive and negative activation maps should be considered, and the maximal cluster of these two maps, regardless of polarity, should be used to localize the SOZ. In the second study, the concept was tested using iEEG-fMRI and it was found that the use of the maximal negative cluster had limited utility for SOZ localization. The results of this thesis provide a new method for preparing EEG data from iEEG-fMRI experiments and it shows that the bulk of maximal negative fMRI clusters have limited reliability for clinical applications.

description: Despite the no-go theorem [5] which rules out static stable solitons in Galileon theory, we propose a family of solitons that evade the theorem by traveling at the speed of light. These domain-wall-like solitons are stable under small fluctuations-analysis of perturbation shows neither ghost-like nor tachyon-like instabilities, and perturbative collision of these solitons suggests that they pass through each other asymptotically, which maybe an indication of the integrability of the theory itself.
