title: Artistic Expression and Personal Identity: The Figure of the Huntress in Virgil’s Aeneid and Ovid’s Metamorphoses

description: The huntress who endeavours to remain unwed is at variance with the Roman girls and young women who almost universally become wives (and mothers). Why, then, is this seemingly unconventional literary figure of such interest to the early Imperial Latin poets Virgil and Ovid? In order to ascertain this, this thesis attempts to answer the following questions pertaining to the “how” and “why” of the huntress’ depiction in Virgil’s Aeneid and Ovid’s Metamorphoses: did the poets adhere to any sort of paradigm for the huntress (the “how”); and why did they include the huntress in their poems (the “why”). My methodological approach to answer these questions comprises lexical analyses of the passages containing these characters and the categorization of the data on the huntress’ characterization drawn from them according to the five characteristics that I propose comprise the huntress. The “how” of Virgil’s huntress consists of a paradigm, while Ovid does not have one. With respect to the question of “why”, the huntress is a means for Virgil to express the idea of the hunt in the Aeneid and permits a high level of creative expression that other female characters do not. Ovid’s purpose for including her in the Metamorphoses is to explore certain ideas relating to rape and the “erotic hunt” and the opposition of specific concepts pertaining to sexual/romantic relationships. Since the literary huntress is a diametric character to actual Roman girls and young women, the larger question arises about whether these poets’ ideas about the former reflect anything about their attitudes towards the latter. It is the case for Virgil that they do, and, building on Ramsby’s arguments about Roman women and autonomy, I argue that he uses the huntress to express his observations regarding women in his society. Ovid, on the other hand, seems to use the huntress to convey the theme of victimization with respect to personal identity which involves the huntress being forced to give up her identity due to the interference from a god or goddess, a theme which I suggest may have personally resonated with him.

description: We extend our earlier results delineating the supersymmetry (SUSY) reach of the CERN Large Hadron Collider operating at a centre-of-mass energy \sqrt{s}=7 TeV to integrated luminosities in the range 5 - 30 fb^{-1}. Our results are presented within the paradigm minimal supergravity model (mSUGRA or CMSSM). Using a 6-dimensional grid of cuts for the optimization of signal to background ratio -- including missing E_T-- we find for m(gluino) \sim m(squark) an LHC 5σSUSY discovery reach of m(gluino) \sim 1.3,\ 1.4,\ 1.5 and 1.6 TeV for 5, 10, 20 and 30 fb^{-1}, respectively. For m(squark)>> m(gluino), the corresponding reach is instead m(gluino)\sim 0.8,\ 0.9,\ 1.0 and 1.05 TeV, for the same integrated luminosities.

description: Following the adoption of the Paris Agreement, there has been an increasing interest in quantifying impacts at discrete levels of global mean temperature (GMT) increase such as 1.5 °C and 2 °C above pre-industrial levels. Consequences of anthropogenic greenhouse gas emissions on agricultural productivity have direct and immediate relevance for human societies. Future crop yields will be affected by anthropogenic climate change as well as direct effects of emissions such as CO2 fertilization. At the same time, the climate sensitivity to future emissions is uncertain. Here we investigate the sensitivity of future crop yield projections with a set of global gridded crop models for four major staple crops at 1.5 °C and 2 °C warming above pre-industrial levels, as well as at different CO2 levels determined by similar probabilities to lead to 1.5 °C and 2 °C, using climate forcing data from the Half a degree Additional warming, Prognosis and Projected Impacts project. For the same CO2 forcing, we find consistent negative effects of half a degree warming on productivity in most world regions. Increasing CO2 concentrations consistent with these warming levels have potentially stronger but highly uncertain effects than 0.5 °C warming increments. Half a degree warming will also lead to more extreme low yields, in particular over tropical regions. Our results indicate that GMT change alone is insufficient to determine future impacts on crop productivity.

description: Giant liver fluke (Fascioloides magna) is a parasitic worm found in wild and domestic ruminants in North America. Infection with F. magna, known as fascioloidiasis, causes liver damage, fibrosis, and inflammation that can negatively impact the fitness of hosts. In Elk Island National Park (EINP), Alberta, Canada, this parasitic disease is suspected to contribute to the ongoing moose population decline. To manage the park’s moose population, fluke control measures, including anthelmintic treatment and environmental control strategies, can reduce the prevalence of fascioloidiasis. However, efficient, targeted interventions require knowledge on the fine-scale distribution of the parasite. In this thesis, I investigated the epidemiology of F. magna to guide an effective and minimally invasive fluke control program in EINP. First, I developed and validated a molecular assay to detect F. magna in freshwater snails. A multiplex qPCR assay was created to specifically target F. magna as well as an internal amplification control endogenous to freshwater snails. I used this assay, along with its constituent singleplex assay, to diagnose F. magna infections in lymnaeid snails from EINP. The singleplex assay proved to be more sensitive than the multiplex, making it a more accurate tool for epidemiological surveys. Stagnicola elodes was identified as an intermediate host species of F. magna in EINP, with an estimated prevalence of 5.8%. Second, I determined the spatial distribution of F. magna and its snail host in EINP and assessed whether environmental factors could predict their occurrence among water bodies. I found that snail hosts for F. magna were generally widespread across the park and were associated with physiochemical and plant-related environmental indicators at water bodies. Snail infections with F. magna were relatively rare, observed at only 12% of sites. Using remote-sensing environmental data, I created fine-scale predictive models to forecast the occurrence of snail hosts and F. magna-infected snails across water bodies. However, these predictive occupancy models demonstrated poor predictive accuracy. This work has contributed a molecular tool for the surveillance of F. magna, explored the utility of ecological niche modeling for the epidemiological control of the parasite, and furthered our understanding of fascioloidiasis in EINP.

description: Pipelines are an essential infrastructure for the transportation of fluids and gases in many industries. Leaks in pipelines present significant environmental and economic concerns, making accurate and timely leak detection crucial. Recent advances in deep learning, particularly sequential models, have shown promising capabilities in anomaly detection for time series data. However, the challenge remains to detect leaks accurately while minimizing false alarms. This paper presents a novel approach combining the CB-AttentionNet model, which integrates a 1D convolutional neural network (CNN), bidirectional long short-term memory (BiLSTM), and multi-head attention mechanisms to capture local and long time series dependencies. Additionally, we introduce a probabilistic search framework using Monte Carlo methods to optimize window sizes dynamically, addressing the limitations of fixed window sizes in handling variable-length sequential data. Experimental results demonstrate that our method performs better in terms of accuracy and reducing false positives across various simulations with industrial pipeline data. Optimized window sizes, particularly between 45 and 60 seconds, offer an effective balance between reducing misclassified leaks and maintaining high training accuracy. Furthermore, our analysis of resource usage and evaluation time shows that the model’s performance is efficient and manageable within typical operational constraints.

description: Brane dark energy cosmologies, leading to various possible evolutions of our universe, are investigated. The discussion shows that while all these models can be made arbitrarily close to the standard $Λ$CDM cosmology at present, their future evolutions can be very different, even diverge with time in a number of ways. This includes asymptotic de-Sitter evolution, Little Rip with dissolution of bound structures, and various possible singularities, as the Big Rip, a sudden future singularity (Type II), and Type III and Type IV cases. Specifically, some interesting effects coming from the brane tension are investigated. It is shown, in particular, that the Little Rip occurs faster on the brane model than in usual FRW cosmology. And in the asymptotic de-Sitter regime the influence of the brane tension leads to a deviation of the value of the effective cosmological constant from that corresponding to ordinary dark energy. As a consequence, the value of the inertial force from the accelerating expansion can greatly exceed the corresponding inertial force in ordinary cosmological models.

Social protection in transnational contexts [Working paper]

This working paper is a literature review on transnational social protection practices, and is part of the research project "The role of transnational social fields in the emergence, maintenance and decline of ethnic and demographic enclaves" (CSO2015-68687-P) ( 2016-2020), financed by the Ministry of Economy, Industry and Competitiveness (MINECO) of the Government of Spain, in the call for excellence projects of the National R & D Plan.

Summary. In this paper we analyze the results of studies on social protection systems used by migrants in transnational spaces. To do this, we start by reviewing the concepts of "transnationalism" and "transnational social field" in order to analyze the main transnational practices of migrants. Finally, we study the concept of transnational social protection and its relationship and intersection with the practices that often take place in transnational social fields.

description: The pseudopotential theory is extended to the Bogoliubov-de Gennes equations to determine the excess energy when one atom is added to the trapped superfluid Fermi system with even number of atoms. Particular attention is paid to systems being at the Feshbach resonance point. The results for relatively small particle numbers are in harmony with the Monte-Carlo calculations, but are also relevant for systems with larger particle numbers. Concerning the additional one quasiparticle state we define and determine two new universal numbers to characterize its widths.

description: Symmetric Teleparallel Gravity allows for the reformulation of gravity in the form of nonmetricity by vanishing the contorsion term in the generic affine connection. Our focus is on investigating a recently proposed extension of this theory in which the Lagrangian has the form $f(Q,C)$ by incorporating the boundary term $C$. In this work, we first use a reconstruction approach in $f(Q,C)$ gravity that might admit the $Λ$CDM expansion history. Furthermore, we perform a novel approach for cosmological reconstruction of $f(Q,C)$ gravity in terms of e-folding, and it shows how any FLRW cosmology can arise from a specific $f(Q,C)$ gravity. A variety of instances are provided using this approach in which $f(Q, C)$ gravity is reconstructed to yield the well-known cosmic evolution: $Λ$CDM era, acceleration/deceleration era which is equivalent to the presence of phantom and non-phantom matter, late-time acceleration with the crossing of phantom-divide line and transient phantom era.

description: Multiple sclerosis (MS) is a common inflammatory demyelinating and neurodegenerating disease of the central nervous system impacting over 2.8 million people worldwide. Most people start MS with a relapsing-remitting form (RRMS), yet no two persons have the same disease course. Many of them will develop a secondary-progressive course (SPMS) despite treatment, causing dramatic health and socioeconomic consequences. Early accurate measurement of disease activity will permit early effective treatment for improved prognosis. But there is no established method to classify these two subtypes beforehand clinically. By leveraging the power of deep learning such as convolutional neural networks (CNNs), this project aims to optimize personalized disease characterization using standard clinical data especially brain magnetic resonance imaging (MRI). Specifically, based on 140 clinical participants with RRMS or SPMS, the research targets phenotype prediction through a series of development and validation processes. These included data optimization, model development and testing based on both 2D- and 3D- CNN models, and model interpretation using a recognized method called gradient-class activation mapping (Grad- CAM). Results showed that axial images normalized with a Z-score like approach were most feasible. Both the 2D and 3D models achieved >80% accuracy in predicting RRMS and SPMS, where combining both MRI and clinical variables appeared to perform better than either data type alone. The Grad-CAM analysis helped discern critical brain areas related to each MS subtype. These findings underscore the potential of deep learning based completely on clinical care data to detect disease activity, marking early diagnosis and personalized treatment possible.

Im Mittelpunkt dieser Leitlinien steht das Verständnis, dass jedes KI-Produkt oder -Verfahren als Instrument zur Förderung und Wahrung der in der Allgemeinen Erklärung der Menschenrechte verankerten Rechte dienen muss. Diese vorläufigen Leitlinien sind in mehrere Abschnitte gegliedert und bieten den Parlamenten allgemeine Anhaltspunkte für die schrittweise Entwicklung eines eigenen Regelungsrahmens.
title: Tuning the Catalytic Performance of Nitrogen- and Iron-Nitrogen-Doped Mesoporous Carbons for CO2 Reduction
Creators: name: Li, Jialang
Publisher: name: Graduate Studies
Year: 2024
Subjects: subject: Chemistry--Physical

description: This thesis systematically explores the catalytic performance of nitrogen-doped and iron-nitrogen co-doped mesoporous carbon materials for electrochemical CO2 reduction (CO2RR). It particularly examines the effects of nitrogen doping speciation, structural disorder, various pore sizes, and single iron atom incorporation on catalytic performance. First, this research compares the CO2RR performance of N-doped mesoporous carbon materials in both powder (CIC) and self-supported film (NCS). These two materials were prepared using the same process except that the CICs are powder and the NCS is tape-casted into a film. Physical characterization revealed that the N-doped carbon powders possess a more disordered carbon wall structure and more micropores than the sheets, while X-ray photoelectron spectroscopy indicates a higher content of pyridinic nitrogen in the powder (53% of the total nitrogen content). The CO2RR experiments showed that the N-doped CIC-12 exhibits the highest FECO of 97%, higher than the 50% FECO shown by the N-NCS-12, attributed to the higher pyridinic N content and more structural disorder providing more active sites. Then the effect of varying pore sizes in N-doped CIC powders was explored, comparing with another method of templating carbon synthesized via aniline pyrolysis and having 22 nm pores (AD-22), containing 6 at% graphitic nitrogen and exhibiting lower structural disorder due to the absence of NH3 etching. N-doped CIC-12, with the highest structural disorder and pyridinic nitrogen, achieved 97% FECO at -0.45 V vs. RHE, while CIC-85 and CIC-22 gave lower FECO values. AD-22, containing only graphitic nitrogen, showed no CO2RR activity, confirming the inactivity of graphitic N towards CO2RR. This part of the work resulted in a first-time structure-property-performance relationship for CO2RR at N-doped carbons. Finally, the medium-performing N-CIC-85 powder was used to introduce single iron atoms to further enhance the CO2RR performance. The Fe-NCIC-85 catalysts, synthesized at 900 °C, achieved an excellent FECO of 97% at -0.45 V vs. RHE and maintained this high selectivity for over 100 hours without any signs of loss of stability beyond that. This enhancement was attributed to single-atom iron stabilization by the nitrogen doped onto the CIC powder surface during preparation through NH3 exposure.
Knowing women : Sei Shōnagon's Makura no sōshi in early-modern Japan
Creators: name: Ivanova, Gergana Entcheva
Publisher: name: University of British Columbia
Year: 2012

description: This dissertation explores the reception history of Makura no sōshi (The Pillow Book, 11th c.) from the seventeenth through the nineteenth centuries. Focusing on an extensive body of texts, including scholarly commentaries, erotic parodies, and instruction manuals for women, I examine how Makura no sōshi and the image of its female author Sei Shōnagon were transformed through shifts in political contexts, readerships, and socio-cultural conditions. The complex reception history of The Pillow Book, in which the text was recreated through diverse forms, serves as a useful case study of how literary criticism, gender structures, and the status of women have changed through time. Drawing from research on the invention of national literatures and the historical reception of Japanese “classical” works, this study reveals the processes and agents that contributed to the shifting place of Makura no sōshi within Japanese literature. By so doing, it sheds light on the extent to which misrepresentations of Heian texts and their authors have influenced approaches in literary scholarship and shaped contemporary images of the Heian period as a whole. The Introduction analyzes the context in which Makura no sōshi was produced and considers theoretical approaches to the reception of literary works, particularly the processes of evaluation, interpretation, adaptation, and canonization. Chapter One traces scholarly debates regarding the textual identity and the genre of the work as recorded in scholarly commentaries and works of literary criticism. Chapter Two takes up the popularization of the Heian text among male readers and considers its transformation into a highly eroticized work. An examination of illustrated adaptations of Makura no sōshi for a female readership follows in Chapter Three, which shows how the work was used as a manual for social mobility gained through marriage. Chapter Four turns to constructions of Sei Shōnagon in instruction manuals for women and examines the use of the image of the author as an efficient tool for gender training both in Edo (1603-1868) and Meiji (1868-1912) Japan. The Conclusion summarizes aspects of Makura no sōshi that defy categorization and make it a dynamic text.

description: We explore fermionic T-duality and self-duality in the geometry AdS3 x S3 x T4 in type IIB supergravity. We explicitly construct the Killing spinors and the fermionic T-duality isometries and show that the geometry is self-dual under a combination of two bosonic AdS3 T-dualities, four fermionic T-dualities and either two additional T-dualities along T4 or two T-dualities along S3. In addition, we show that the presence of a B-field acts as an obstacle to self-duality, a property attributable to S- duality and fermionic T-duality not commuting. Finally, we argue that fermionic T-duality may be extended to CY2 = K3, a setting where we cannot explicitly construct the Killing spinors.

description: One hundred and twenty-four coal and coaly shale samples were collected from a 13-meter-thick coal open mining section of the early Eocene Guchengzi Formation in the Fushun Basin, NE China. The coals and coaly shales from the Eocene Guchengzi Formation were deposited in an oxic environment and are classified within the subbituminous A rank. Rock-Eval hydrogen index values indicate the presence of Type II2-III kerogens. Molecular compositions were determined using gas chromatography-mass spectrometry (GC-MS) to diagnose source inputs and assess depositional conditions. The n-alkane distribution in these samples is characterized by a dominance of long-chain odd-numbered n-alkanes, exhibiting high odd-to-even preference. The isoprenoid distribution is marked by a high pristane/phytane (Pr/Ph) ratio, which is indicative of oxic conditions during organic matter formation. The samples show high concentrations of bicyclic sesquiterpanes, tricyclic diterpanes, tetracyclic diterpanes, and hopane homologs, along with low concentrations of steranes and the absence of oleanane. This suggests a dominance of gymnosperm biomass input with significant bacterial activity. Aromatic hydrocarbons in the samples are dominated by naphthalene, phenanthrene, and their alkylated homologs, with a low abundance of four- and five-ring aromatic hydrocarbons. Various higher plant-derived aromatic hydrocarbons were identified, including 1,2,5-trimethylnaphthalene, 1,2,5,6-tetramethylnaphthalene, cadalene, 6-isopropyl-1-isohexyl-2-methylnaphthalene, 1,7-dimethylphenanthrene, simonellite, and retene. The distribution of combustion-derived polycyclic aromatic hydrocarbons such as fluoranthene, pyrene, benzo[a]anthracene, and various benzofluoranthenes and benzopyrenes suggests that forest fires occurred in the study area during the early Eocene period. Molecular constituents provide valuable insights into the paleoenvironmental conditions and the type of vegetation contributing to the organic matter in the Fushun Basin during the early Eocene. The geochemical data highlight the complex interplay between terrestrial and aquatic inputs, bacterial activity, and environmental factors such as forest fires, all of which played a significant role in shaping the depositional environment of the Guchengzi Formation coals and coaly shales.

description: We provide a deterministic-control-based interpretation for a broad class of fully nonlinear parabolic and elliptic PDEs with continuous Neumann boundary conditions in a smooth domain. We construct families of two-person games depending on a small parameter which extend those proposed by Kohn and Serfaty (2010). These new games treat a Neumann boundary condition by introducing some specific rules near the boundary. We show that the value function converges, in the viscosity sense, to the solution of the PDE as the parameter tends to zero. Moreover, our construction allows us to treat both the oblique and the mixed type Dirichlet-Neumann boundary conditions.

description: A fundamental limit to the sensitivity of optical interferometers is imposed by Brownian thermal fluctuations of the mirrors' surfaces. This thermal noise can be reduced by using larger beams which "average out" the random fluctuations of the surfaces. It has been proposed previously that wider, higher-order Laguerre-Gaussian modes can be used to exploit this effect. In this article, we show that susceptibility to spatial imperfections of the mirrors' surfaces limits the effectiveness of this approach in interferometers used for gravitational-wave detection.

description: The relevant quasipotential near an equilibrium point is determined by a new linear matrix equation, with less unknowns than an existing (possibly nonlinear) one. This also assures the asymptotic fulfillment of the Fokker-Planck equation, even globally due to the second term in the noise strength. An auxiliary result for the exit problem is derived as well.

description: Water is a major factor limiting crop production in many regions around the world. Irrigation can greatly enhance crop yields, but the local availability and timing of freshwater resources constrains the ability of humanity to increase food production. Innovations in irrigation infrastructure have allowed humanity to utilize previously inaccessible water resources, enhancing water withdrawals for agriculture while increasing pressure on environmental flows and other human uses. While substantial additional water will be required to support future food production, it is not clear whether and where freshwater availability is sufficient to sustainably close the yield gap in cultivated lands. The extent to which irrigation can be expanded within presently rainfed cropland without depleting environmental flows remains poorly understood. Here we perform a spatially explicit biophysical assessment of global consumptive water use for crop production under current and maximum attainable yield scenarios assuming current cropping practices. We then compare these present and anticipated water consumptions to local water availability to examine potential changes in water scarcity. We find that global water consumption for irrigation could sustainably increase by 48% (408 km3 H2O yr−1)—expanding irrigation to 26% of currently rainfed cultivated lands (2.67 × 10^6 km2) and producing 37% (3.38 × 10^15 kcal yr−1) more calories, enough to feed an additional 2.8 billion people. If current unsustainable blue water consumption (336 km3 yr−1) and production (1.19 × 10^15 kcal yr−1) practices were eliminated, a sustainable irrigation expansion and intensification would still enable a 24% increase in calorie (2.19 × 1015 kcal yr−1) production. Collectively, these results show that the sustainable expansion and intensification of irrigation in selected croplands could contribute substantially to achieving food security and environmental goals in tandem in the coming decades.

description: We extract diffractive parton distribution functions (DPDFs) and diffractive structure functions from the most recent H1 and ZEUS diffractive DIS data obtained by various methods. We consider Pomeron as an object with parton distribution function, evolving according to the next-to-leading order (NLO) DGLAP equations within the framework of the `Fixed Flavour Number Scheme' (FFNS). Having performed a global fit analysis, we achieve a very good description of all available measurements by introducing a new set of quark distribution form for the Pomeron. We predict longitudinal and charm proton diffractive structure function as well. Our results are compared with other analysis from the literature.

description: Da der Einsatz von Künstlicher Intelligenz (KI) in den parlamentarischen Prozessen immer mehr zunimmt, ist es notwendig, ethische und operative Leitlinien festzulegen, die Rechenschaftspflicht, Transparenz und menschliche Autonomie gewährleisten und gleichzeitig die Ziele der nachhaltigen Entwicklung fördern sowie Datenschutz, Sicherheit und Vielfalt schützen. Zu diesem Zweck wurde anlässlich der Konferenz "LegisTech: the Americas" in Brasília (13.-14. April 2023) eine technische Arbeitsgruppe einberufen, um eine erste Reihe von Leitlinien zu entwickeln, in denen die ethischen und operativen Grundsätze für die Einführung und Nutzung von KI im parlamentarischen Arbeitsbereich dargelegt werden. Im Mittelpunkt dieser Leitlinien steht das Verständnis, dass jedes KI-Produkt oder -Verfahren als Instrument zur Förderung und Wahrung der in der Allgemeinen Erklärung der Menschenrechte verankerten Rechte dienen muss. Diese vorläufigen Leitlinien sind in mehrere Abschnitte gegliedert und bieten den Parlamenten allgemeine Anhaltspunkte für die schrittweise Entwicklung eines eigenen Regelungsrahmens.
Assessment of the Red Sea ecosystem with emphasis on fisheries

description: A comprehensive assessment of the Red Sea large marine ecosystem (LME), with emphasis on fisheries, was carried out using several approaches. The assessment started with a multidisciplinary rapid appraisal of the sustainability of the fisheries using standardized attributes in ecological, economic, social, technical and ethical fields. Then a time-series assessment of the fishery was carried out using data from interviews and the reconstruction of catch from 1950 - 2006. A case study to estimate the unreported catch by quantifying qualitative information on incentives to misreport was carried out for Eritrean fisheries. Finally, a comprehensive and detailed assessment was done in an ecosystem-based framework using the modelling tool Ecopath with Ecosim (EwE), which quantifies the trophic interactions of the organisms and fisheries. It was used to predict the impact of different scenarios of fisheries on the ecosystem and explore the conflict between artisanal and industrial fisheries. Uncertainty analysis was carried out for the different assessment methods employed. The results of the assessments have varying levels of detail: relative ranking of the sustainability of fisheries in the rapid appraisal assessment, relative quantitative changes over time in the interview analysis, actual historic quantitative assessment of the catches in the catch reconstruction, and finally a quantitative assessment with potential to predict future scenarios using ecosystem modelling. The results give a holistic understanding of the Red Sea ecosystem and its fisheries. The data and resources needed increased as the details of the outputs increased. The assessments complemented each other and there are similarities in the results. They all showed declines in all fisheries, except for beach seining. Sharks, the top predator of the system, showed the worst decline in all the assessments; and the interview and catch reconstruction methods gave strikingly similar results for sharks. The ecosystem modelling did not show direct impact between artisanal and industrial fishery sectors due to the lack of trophic interactions. In addition, the thesis demonstrates that fishery researchers and practitioners can utilize different assessment tools, given the resources at their disposal, to assist the management of resources to conserve ecosystems and livelihoods.

description: Glioblastoma (GBM) is the most common and lethal primary brain malignancy in adults, characterized by therapeutic resistance and inevitable relapse. Major clinical challenges are imposed by extensive intra-tumoral heterogeneity, diffuse infiltrative growth of the tumor, and bi-directional interactions with diverse non-malignant cell-types within the brain tumor microenvironment (TME). A better understanding of how the tumor cells organize spatially and interact with the TME to promote growth and invasion may reveal opportunities for improved therapeutic strategies. In this thesis, I explore transcriptional heterogeneity within the glioblastoma ecosystem using spatially profiled, temporal samples of GBM xenograft models. The species-specific distinction of the human tumor and mouse TME, coupled with spatial resolution, overcomes previous limitations in studying the invasive front and delineating co-existing non-malignant components within the tumor. By applying a novel computational framework based on unsupervised deconvolution, I characterize a compendium of 15 tumor cell gene expression programs set within the context of 90 mouse brain and TME cell types, cell activities, and anatomic structures. This approach reveals the spatial organization of tumor programs along an axis corresponding to tumor density and distinct colocalization patterns with spatiotemporally varying TME components. Notably, tumor-associated macrophages and reactive astrocytes colocalized with the tumor early in its growth, while an outward gradient of invasion programs, centered on hypoxia, was observed with tumor progression. Moreover, distinct tumor programs aligned with well-documented routes of GBM invasion including the white-matter tracts, perivasculature and parenchymal routes. Ligand-receptor analyses highlighted neuronal and extra-cellular matrix (ECM) signaling along these routes, and further analyses indicated that these routes could be distinguished by the expression of tumor and TME-derived ECM molecules. Lastly, using a network-graph of predicted protein-protein interactions, I identified sub-modules of genes serving as program network hubs that were highly prognostic in patient datasets. Taken together, spatial profiling of xenografts has revealed a granular repertoire of transcriptional programs and provides a basis for rational targeting of tumor and/or TME niches within the GBM ecosystem, paving the way for improved therapeutic interventions.
