Evaluation of the effects of bolus air gaps on surface dose in radiation therapy and possible clinical implications
Creators: name: Shaw, Adam
Publisher: name: University of British Columbia
Year: 2018

description: In clinical radiotherapy, treatments are frequently delivered using photons with energies in the Megavoltage range. The advantage of such beam energies is that the majority of dose is deposited deeper within the patient, with the depth of maximum dose being up to several centimetres beyond the patient’s skin. This effect allows radiotherapists to target tumours on organs such as the prostate. However, there are times when larger doses must be deposited to the near-skin region. In these cases, a layer of ”substitute tissue” called a bolus is applied, to shift dose towards the patient’s skin. Given the natural contours of the human body, it is difficult for a bolus to achieve perfect contact with the patient and air gaps are often present between the applied bolus and the patient’s surface. Such air gaps have the potential to disturb the distribution of surface dose. In this thesis we present an investigation into the magnitude of the effects of bolus-surface air gaps on 6 MV photon beam surface dose. Using a combination of ionization chamber measurements, film dosimetry, and Monte Carlo simulations, we establish that surface dose is significantly reduced in the presence of an air gap. The observed reduction in dose increases as the distance between the bolus material and the phantom surface increases, and is more severe at smaller field sizes. By examining simulated and experimentally measured surface-dose-profiles, we demonstrate that bolus-surface gaps alter the shape of the dose distribution near the field boundary. We find that surface dose is reduced near the inside of the field edge, with a corresponding increase in dose in the region outside of the defined field. We propose that this effect is caused by low-energy electrons that are generated within the bolus material, near the field edges, but are then scattered outside of the treatment region when passing through the air gap. As such we would recommend that care be taken to reduce the size of any air gaps to below 1 cm, especially in cases with weaker treatment beams and where the PTV is located near to at-risk organs.

description: We investigate atomic force microscope nanolithography of single and bilayer graphene. In situ tip current measurements show that cutting of graphene is not current driven. Using a combination of transport measurements and scanning electron microscopy we show that, while indentations accompanied by tip current appear in the graphene lattice for a range of tip voltages, real cuts are characterized by a strong reduction of the tip current above a threshold voltage. The reliability and flexibility of the technique is demonstrated by the fabrication, measurement, modification and re-measurement of graphene nanodevices with resolution down to 15 nm.

description: In this paper, we propose an averaging method for expert segmentation proposals of microbial organisms, resulting in a smooth, naturally looking segmentation ground truth. The approach exploits a geometrical property of the majority of the organisms - star-shapedness - and is based on contour averaging in polar space. It is robust and computationally efficient, where robustness is due to the absence of tuneable parameters. Moreover, the algorithm preserves the uncertainty (in terms of the standard deviation) of the experts' opinion, which allows to introduce an uncertainty-aware metric for estimation of the segmentation quality. This metric emphasizes the influence of ground truth regions with low variance. We study the performance of the proposed averaging method on time-lapse microscopy data of Corynebacterium glutamicum and the uncertainty-aware metric on synthetic data.

description: We study the effect of entropy injection in the intracluster medium (ICM) in light of the recent observationally determined universal pressure profile of the ICM. Beginning with a power-law entropy profile that is expected in the absence of any feedback, we show that a simple universal prescription of entropy injection results in the final, observed universal pressure profile. This simple prescription has two components, one associated with an overall increase in entropy and another associated with injection in the central parts of the cluster. Importantly, both the components of entropy injection are needed to produce the final universal pressure profile. This is indicative of a need of both preheating the ICM as well {\it in situ} AGN/SNe heating. We demonstrate the usefulness of the method by extending the calculations to clusters at high redshift, and predict redshift evolution of cluster scaling relations that can be tested against data. We show that the self-similar evolution of the universal pressure profile is equivalent to a negative evolution of entropy injection with redshift, with a scaling $S_{inj} \propto (1+z)^{-0.8} S_{inj}(z=0)$. We also show the current observational data are indicative of the entropy injection decreasing with redshift.

description: We analysed 866 observations of the neutron-star low-mass X-ray binary XTE J1701-462 during its 2006-2007 outburst. XTE J1701-462 is the only example so far of a source that during an outburst showed, beyond any doubt, spectral and timing characteristics both of the Z and atoll type. We found that the lower kHz QPO in the atoll phase has a significantly higher coherence and fractional rms amplitude than any of the kHz QPOs seen during the Z phase, and that in the same frequency range, atoll lower kHz QPOs show coherence and fractional rms amplitude, respectively, 2 and 3 times larger than the Z kHz QPOs. Out of the 707 observations in the Z phase, there is no single observation in which the kHz QPOs have a coherence or rms amplitude similar to those seen when XTE J1701-462 was in the atoll phase, even though the total exposure time was about 5 times longer in the Z than in the atoll phase. Since it is observed in the same source, the difference in QPO coherence and rms amplitude between the Z and atoll phase cannot be due to neutron-star mass, magnetic field, spin, inclination of the accretion disk, etc. If the QPO frequency is a function of the radius in the accretion disk in which it is produced, our results suggest that in XTE J1701-462 the coherence and rms amplitude are not uniquely related to this radius. Here we argue that this difference is instead due to a change in the properties of the accretion flow around the neutron star. Regardless of the precise mechanism, our result shows that effects other than the geometry of space time around the neutron star have a strong influence on the coherence and rms amplitude of the kHz QPOs, and therefore the coherence and rms amplitude of the kHz QPOs cannot be simply used to deduce the existence of the innermost stable circular orbit around a neutron star.

description: Real-world sculptures that display patient imaging data for anatomical education purposes have seen a recent resurgence through the field of data physicalization. In this paper, we describe an automated process for the computer-assisted generation of sculptures that can be employed for anatomical education among the general population. We propose a workflow that supports non-expert users to generate and physically display volumetric medical data in a visually appealing and engaging way. Our approach generates slide-based, interactive sculptures-called volograms-that resemble holograms of underlying medical data. The volograms are made out of affordable and readily available materials (e.g., transparent foils and cardboard) and can be produced through commonly available means. To evaluate the educational value of the proposed approach with our target audience, we assess the volograms, as opposed to classical, on-screen medical visualizations in a user study. The results of our study, while highlighting current weaknesses of our physicalization, also point to interesting future directions.

description: Electronic phase separation and related inhomogeneity is ubiquitously seen in strongly-correlated systems. A typical example is found between ferromagnetic metal and antiferromagnetic insulator in CMR manganese oxides. Here we demonstrate that the geometrical frustration brings distinctive aspects into the phase separation phenomena. From Monte Carlo simulation and a simple energy comparison for the pyrochlore double-exchange model, we show that such phase separation takes place between ferromagnetic and paramagnetic metals. We discuss the relevance of our results to a spin-glassy metallic phase found in Mo pyrochlore oxides under external pressure.

description: 4D Flow MRI is a recent promising technology that is able to capture blood flow information within the heart chambers over a cardiac cycle. To accurately study the flow inside the chambers, there is a need for a high quality anatomical reference which can be provided by another scan known as 3D cine MRI (short-axis 3D (multiple 2D slices) cine SSFP). To take advantage of both scans, data fusion can be done using an intensity-based registration. To reduce the impact of noise on the registration result and the chance of misalignment between the organs, defining a region of interest (localization) should be done prior to the registration. Localizing a dataset - especially a time-varying dataset - can be a daunting task since the localization should be provided for all time frames. We design and evaluate different strategies for extending single time frame localization to time varying data in order to register the 4D Flow MRI and 3D cine MRI over the cardiac cycle.

description: Die Masterarbeit Schlupflöcher im Anthropozän: Moralische Wertanpassungen und digitale Mediensysteme als emergente Möglichkeiten der posthumanen Adaption beschäftigt sich mit dem Begriff des „Anthropozän“ und dessen Entwicklung im posthumanistischen Zeitalter. Anhand gesellschaftlicher Entwicklungen und moderner Technologien werden die für den Menschen essentiellen Lebensbedingungen untersucht und mögliche Lösungsansätze für die Anthropozänbewältigung erkundet. Die Forschungsfrage lautet: Gibt es digitale oder alternative Schlupflöcher, die uns dabei verhelfen, dem garantierten Kollaps des Anthropozän zu entfliehen? Den Ergebnissen nach zu urteilen, könnten Altruismus, eine frühkindliche Erziehung, sowie eine gesetzlich festgelegte und moralisch geprüfte Nutzung von autonomen und immersiven Medien als sinnvolle Lösungsstrategien der fortschreitenden Entwicklungen betrachtet werden. Weltraumbergbau und transgenetische Kunst werfen derzeit noch vermehrt kritische Fragen bei der Umsetzung auf. Da Gesellschaftliches und Ökologisches im Anthropozän fließend ineinander übergehen, müssten laut Schwartz drei spezifische Existenzansprüche gegeben sein, um ein rundum erfülltes Menschenleben zu sichern: Zum einen muss die Verwirklichung eigener Bedürfnisse erfolgen (1). Zum anderen benötigen Menschen ein geordnetes soziales Vernetzungssystem (2). Und das Stillen von Bedürfnissen der Gruppe ist die dritte, unabdingbare Anforderung (3). Das von der „Industrie 4.0“ ins Leben gerufene Motto „Wohlstand für alle durch Nachhaltigkeit“ spiegelt sich in den transkulturell erforschten Hauptprinzipien „Wachstum“ und „Schutz“ wider. Daher sollte dieses Ziel weiterhin angestrebt, aber von einem guten Maß an Selbstarbeit („Shadow Work“) begleitet und im Rahmen eines inklusiven, offenen Diskurses diskutiert werden.

description: Reductionism has dominated science and philosophy for centuries. Complexity has recently shown that interactions---which reductionism neglects---are relevant for understanding phenomena. When interactions are considered, reductionism becomes limited in several aspects. In this paper, I argue that interactions imply non-reductionism, non-materialism, non-predictability, non-Platonism, and non-nihilism. As alternatives to each of these, holism, informism, adaptation, contextuality, and meaningfulness are put forward, respectively. A worldview that includes interactions not only describes better our world, but can help to solve many open scientific, philosophical, and social problems caused by implications of reductionism.

description: We generalize here our earlier results on particle acceleration by naked singularities. We showed recently[1] that the naked singularities that form due to gravitational collapse of massive stars provide a suitable environment where particles could get accelerated and collide at arbitrarily high center of mass energies. However, we focussed there only on the spherically symmetric gravitational collapse models, which were also assumed to be self-similar. In this paper, we broaden and generalize the result to all gravitational collapse models leading to the formation of a naked singularity as final state of collapse, evolving from a regular initial data, without making any prior restrictive assumptions about the spacetime symmetries such as above. We show that when the particles interact and collide near the Cauchy horizon, the energy of collision in the center of mass frame will be arbitrarily high, thus offering a window to the Planck scale physics. We also consider the issue of various possible physical mechanisms of generation of such very high energy particles from the vicinity of naked singularity. We then construct a model of gravitational collapse to a timelike naked singularity to demonstrate the working of these ideas, where the pressure is allowed to be negative but the energy conditions are respected. We show that a finite amount of mass-energy density has to be necessarily radiated away from the vicinity of the naked singularity as the collapse evolves. Therefore the nature of naked singularities, both at classical and quantum level could play an important role in the process of particle acceleration, explaining the occurrence of highly energetic outgoing particles in the vicinity of Cauchy horizon that participate in extreme high energy collisions.

description: We develop a Fermionic Chern-Simons (CS) theory for the fractional quantum Hall effect in monolayer graphene with SU(4) symmetry, arising from the spin and the valley degrees of freedom, which involves four distinct CS gauge fields. We choose the corresponding elements of the CS coupling matrix such that an even number of spin and valley quantum number dependent flux quanta is attached to all electrons and that any electron with a given spin and valley quantum number sees an integer number of flux attached to other electrons with different (spin and valley) quantum numbers. Using this CS matrix, we obtain a list of possible fractional quantum Hall states that might occur in graphene and propose wavefunctions for those states. Our analysis also applies to fractional quantum Hall states of both bilayer quantum Hall systems without spin polarization and bilayer spin polarized graphene.

description: Pediatric brain tumor radiotherapy research is investigating how radiation influences the development and function of a patient's brain. To better understand how brain growth is affected by the treatment, the brain structures of the patient need to be explored and analyzed pre- and post-treatment. In this way, anatomical changes are observed over a long period and are assessed as potential early markers of cognitive or functional damage. In this early work, we propose an automated approach for the visual assessment of the growth prediction of brain structures in pediatric brain tumor radiotherapy patients. Our approach reduces the need for re-segmentation and the time required for it. We employ as a basis pre-treatment Computed Tomography (CT) scans with manual delineations (i.e., segmentation masks) of specific brain structures of interest. These pre-treatment masks are used as initialization, to predict the corresponding masks on multiple post-treatment follow-up Magnetic Resonance (MR) images, using an active contour model approach. For the accuracy quantification of the automatically predicted posttreatment masks, a support vector regressor (SVR) with features related to geometry, intensity, and gradients is trained on the pre-treatment data. Finally, a distance transform is employed to calculate the distances between pre- and post-treatment data and to visualize the predicted growth of a brain structure, along with its respective accuracy. Although segmentations of larger structures are more accurately predicted, the growth behavior of all structures is learned correctly, as indicated by the SVR results. This suggests that our pipeline is a positive initial step for the visual assessment of brain structure growth prediction.

Excavating a legacy : a contextual study of the Miniature Frescoes from the Neopalatial court complex at Knossos
Creators: name: Brake, Andrea Helene
Publisher: name: University of British Columbia
Year: 2018

description: Sir Arthur Evans was the first official excavator of Knossos, and his legacy is centred on his imaginative creation of Minoan society as a peaceful monarchy of liberal, goddess-worshipping people. Evans’ interpretations and reconstructions, based on his excavations of the court complex at Knossos, have proven difficult to move beyond, despite much scholarly work aimed at dismantling his legacy in order to extract aspects of our understanding of Minoan society that have been dependent on his misleading, biased, or erroneous views. I propose a new, holistic approach to analyzing Evans’ legacy data that incorporates access analysis, proxemics, and embodied archaeology. The aim of this approach is to contextualize a particular group of related artifacts from Evans’ excavations in order to facilitate analyses that might offer new interpretations of the evidence from Knossos, or perhaps confirm Evans’ initial conclusions. As a case study I analyze the Miniature Frescoes from the Neopalatial period at the court complex of Knossos, and incorporate the use of experimental archaeology, specifically an experiment designed to analyze the sensory aspects of the context. Based on my reanalysis, I conclude that the court complex at Knossos may have been a ritual centre for the regional community, and that the room where the fragments of the Miniature Frescoes were discovered may have been a location of preparation for these community events, especially considering the location of this room adjacent to both the Central Court and the North Entrance Passageway. I therefore show that new insights can be gained from engaging in a contextualizing study of legacy data, and that these insights can inform an updated interpretation of the material evidence from Knossos.

description: Eine nachhaltige und physiologisch gesunde Ernährung, die sowohl regionale als auch saisonale Gewohnheiten miteinschließt, zählt zu den Grundlagen eines gesundheitsförderlichen Lebensstils. Nicht nur die Vermeidung von Zivilisationskrankheiten wird durch die angeführte Thematik tangiert, sondern auch die Auseinandersetzung mit der Umwelt spielt eine bedeutende Rolle. Eine für die Alltagsbewältigung von vielen Menschen wesentliche Frage ist dabei, wie eine solche Ernährungsweise bei geringem Haushaltsbudget umgesetzt werden kann. Daher ist es aus fachdidaktischer und pädagogischer Sicht sehr bedeutsam, dass bereits Kindern und Jugendlichen mittels des Fachunterrichtes genau jene Aspekte vermittelt und sowohl theoretisch als auch praktisch näher gebracht werden. Der Unterricht soll das Bewusstsein über die eigene Ernährung und dem Ernährungsverhalten der Schülerinnen und Schüler wecken um sie zu befähigen, im außerschulischen Bereich nach bestem Wissen und Gewissen eine Kaufentscheidung zu treffen. Im Rahmen dieser Masterarbeit wurde anhand von fachwissenschaftlichen und fachdidaktischen Erkenntnissen ein kompetenzorientiertes Lernarrangement für die Sekundarstufe 1 erstellt, das sich mit nachhaltiger Ernährung bei geringem Haushaltsbudget beschäftigt. Dieses Lernarrangement wurde in weiterer Folge in einer Inklusiv- und Sonderpädagogischen Schule in zwei unterschiedlichen Klassengruppen erprobt. Die gesamten Unterrichtssequenzen wurden von einer weiteren Lehrperson auf Basis eines eigens angefertigten Beobachtungsbogens beobachtet und ein Ausschnitt des Unterrichts mittels eines Audioaufnahmegerätes vertont, um Hinweise dahingehend zu bekommen, wie die Schülerinnen und Schüler mit den Unterrichtsmaterialien arbeiten. Das gesamte Datenmaterial wurde abschließend mittels verschiedener qualitativer Datenerhebungsmethoden ausgewertet.

Ozanam’s life encompassed a particularly turbulent time in French history, and he was a witness to two major political upheavals-the overthrow of the Bourbon dynasty that brought Louis Philippe to power in 1830, and the end of Louis Philippe’s “Bourgeois Monarchy” as a result of the 1848 Revolutions. This book examines Ozanam’s life in a variety of ways. First, it explores the various roles he played throughout his life-son, sibling, student, member of and an inspiration for the Society of St. Vincent de Paul, spouse and father, scholar, and spokesperson for the common people. Second, it examines the lessons he learned in his life, including the importance of friendship, the meaning of solidarity, and the role and purpose of suffering, among many others that he shares with those who study his thought and work. It concludes with an account of Ozanam’s enduring legacy.

Antoine Frédéric Ozanam feared that he would not have a fruitful career, but his legacy remains a powerful testimony to his greatness. This book will interest scholars wishing to know more about Ozanam and the period in which he lived, as well as a wider audience including those who are aware or are members of the Society of St. Vincent de Paul.

description: Augmented and virtual reality (XR) are potentially powerful tools for enhancing the efficiency of interactive visualization of complex data in biology and medicine. The benefits of visualization of digital objects in XR mainly arise from enhanced depth perception due to the stereoscopic nature of XR head mounted devices. With the added depth dimension, XR is in a prime position to convey complex information and support tasks where 3D information is important. In order to inform the development of novel XR applications in the biology and medicine domain, we present a survey which reviews the neuroscientific basis underlying the immersive features of XR. To make this literature more accessible to the visualization community, we first describe the basics of the visual system, highlighting how visual features are combined to objects and processed in higher cortical areas with a special focus on depth vision. Based on state of the art findings in neuroscience literature related to depth perception, we provide several recommendations for developers and designers. Our aim is to aid development of XR applications and strengthen development of tools aimed at molecular visualization, medical education, and surgery, as well as inspire new application areas.

Current characteristics of mesoscopic rings in quantum Smoluchowski regime

description: In normal mesoscopic metals of a ring topology persistent currents can be induced by threading the center of the ring with a magnetic flux. This phenomenon is an example of the famous Aharonov-Bohm effect. In the paper we study the current {\it vs} the external constant magnetic flux characteristics of the system driven by both the classical and the quantum thermal fluctuations. The problem is formulated in terms of Langevin equations in classical and quantum Smoluchowski regimes. We analyze the impact of the quantum thermal fluctuations on the current-flux characteristics. We demonstrate that the current response can be changed from paramagnetic to diamagnetic when the quantum nature of the thermal fluctuations increases.

Reducing Model Uncertainty in Crossing Fiber Tractography

description: Diffusion MRI (dMRI) tractography permits the non-invasive reconstruction of major white matter tracts, and is therefore widely used in neurosurgical planning and in neuroscience. However, it is affected by various sources of uncertainty. In this work, we consider the model uncertainty that arises in crossing fiber tractography, from having to select between alternative mathematical models for the estimation of multiple fiber orientations in a given voxel. This type of model uncertainty is a source of instability in dMRI tractography that has not received much attention so far. We develop a mathematical framework to quantify it, based on computing posterior probabilities of competing models, given the local dMRI data. Moreover, we explore a novel strategy for crossing fiber tractography, which computes tracking directions from a consensus of multiple mathematical models, each one contributing with a weight that is proportional to its probability. Experiments on different white matter tracts in multiple subjects indicate that reducing model uncertainty in this way increases the accuracy of crossing fiber tractography.

description: We measure the resistivity and magnetic susceptibility in the temperature range from 5 K to 600 K for the single crystals $A$Fe$_{2-y}$Se$_2$ ($A$ = K$_{0.8}$, Rb$_{0.8}$, Cs$_{0.8}$, Tl$_{0.5}$K$_{0.3}$ and Tl$_{0.4}$Rb$_{0.4}$). A sharp superconducting transition is observed in low temperature resistivity and susceptibility, and susceptibility shows 100% Meissner volume fraction for all crystals, while an antiferromagnetic transition is observed in susceptibility at Neel temperature ($T_N$) as high as 500 K to 540 K depending on A. It indicates the coexistence of superconductivity and antiferromagnetism. A sharp increase in resistivity arises from the structural transition due to Fe vacancy ordering at the temperature slightly higher than $T_{\rm N}$. Occurrence of superconductivity in an antiferromagnetic ordered state with so high $T_{\rm N}$ may suggest new physics in this type of unconventional superconductors.

description: Objective: To study which behavioral components are implemented within participatory health interventions for precision prevention, specifically how they are realized as part of the interventions and how the tailoring of the interventions is implemented. Methods: We selected three case studies of participatory health interventions for precision prevention for three different target groups (children, parents, older adults with chronic conditions). One author with a background in psychology mapped the interventions and the digital functionalities to the 9 intervention functions of the behavioral change wheel (education, persuasion, incentivisation, coercion, training, enablement, modeling, environmental restructuring, restrictions). Results: While the intervention functions persuasion, incentivisation, education, modeling and coercion are implemented in all three interventions under considerations, two techniques (restrictions, and environmental restructuring) were not implemented in any of the three solutions. Training was only applied in one application and enablement in two interventions. We identified significant evidence gaps in both the tailoring process and the effectiveness of behavior change techniques in precision prevention. Conclusion: We conclude that there is a need for more focused studies on the effects of behavior interventions functions in digital health interventions and for design guidelines to improve these interventions for personalized health outcomes, thereby advancing precision prevention in digital health.
Ultrahigh-energy neutrino-nucleon deep-inelastic scattering and the Froissart bound

description: We present a simple formula for the total cross section sigma^{nu N} of neutral- and charged-current deep-inelastic scattering of ultrahigh-energy neutrinos on isoscalar nuclear targets, which is proportional to the structure function F_2^{nu N}(M_V^2/s, M_V^2), where M_V is the intermediate-boson mass and s is the square of the center-of-mass energy. The coefficient in the front of F_2^{nu N}(x, Q^2) depends on the asymptotic low-x behavior of F_2^{nu N}. It contains an additional ln(s) term if F_2^{nu N} scales with a power of ln(1/x). Hence, an asymptotic low-x behavior F_2^{nu N} propto ln^2(1/x), which is frequently assumed in the literature, already leads to a violation of the Froissart bound on sigma^{nu N}.
