description: In this paper we introduce a new approach to study jet substructure in the center-of-mass frame of the jet. We demonstrate that it can be used to discriminate the boosted heavy particles from the QCD jets and the method is complimentary to the existing other jet substructure algorithms. Applications to searches for hadronically decaying W/Z+jets and heavy resonance that decays to a WW final state are also discussed.

description: Sport-related concussion (SRC) is a common injury among Canadian adolescent sport participants (ASP). Numerous factors potentially impact recovery from SRC, including psychological resilience and cortisol. Researchers have found low psychological resilience and low cortisol may be independently linked to increased post-SRC symptom burden and a longer duration of recovery. However, the relationship between resilience and cortisol has not yet been investigated following adolescent SRC, which was the overarching goal of this thesis. The first aim of this study was to explore the trajectory of resilience, as measured by the Connor-Davidson Resilience Scale 10 (CDRISC-10), before and after SRC, controlling for age and sex. Following, we described the relationships between resilience and SRC outcomes, including symptom burden and length of recovery based on physician clearance to return to play. We also aimed to examine group differences in plasma cortisol (stratified by morning [before 11:00am] and basal [11:00am–6:00pm] collection times) between uninjured and post-SRC ASP, controlling for age and sex/menstrual cycle phase (male, female follicular, female luteal), and time of blood draw. We then compared post-SRC cortisol to SRC outcomes controlling for age, and sex/menstrual cycle phase. Finally, we aimed to investigate the associations between resilience and plasma cortisol before and after adolescent SRC. The analyses were stratified by time of cortisol collection as outlined above. Uninjured analyses controlled for age and sex, while post-SRC analyses controlled for age, sex, and symptom severity. We found sex-specific trajectories of resilience following SRC, and that acute post-SRC measures of resilience may better predict SRC outcomes compared to pre-injury measures. Morning and basal cortisol were significantly lower post-SRC for males and females regardless of menstrual cycle phase. Post-SRC morning and basal cortisol demonstrated non-linear relationships with symptom burden, potentially reflecting impairment of the HPA axis and HPA axis activation in response to stress. Finally, morning cortisol decreased with increased resilience in our uninjured participants, but not in our post-SRC participants, suggesting HPA axis impairment following SRC. Overall, the results of this thesis revealed novel aspects of SRC pathophysiology and provide groundwork for future investigations into the complex relationship between resilience, cortisol, and SRC outcomes.

description: Membrane phase behavior has been well characterized in model membranes in vitro under thermodynamic equilibrium state. However, the widely observed differences between biological membranes and their in vitro counterparts are placing more emphasis on nonequilibrium factors, including influx and efflux of lipid molecules. The endoplasmic reticulum (ER) is the largest cellular membrane system and also the most metabolically active organelle responsible for lipid synthesis. However, how the nonequilibrium metabolic activity modulates ER membrane phase has not been investigated. Here, we studied the phase behavior of functional ER in the context of lipid metabolism. Utilizing advanced vibrational imaging technique, that is, stimulated Raman scattering microscopy, we discovered that metabolism of palmitate, a prevalent saturated fatty acid (SFA), could drive solid-like domain separation from the presumably uniformly fluidic ER membrane, a previously unknown phenomenon. The potential of various fatty acids to induce solid phase can be predicted by the transition temperatures of their major metabolites. Interplay between saturated and unsaturated fatty acids is also observed. Hence, our study sheds light on cellular membrane biophysics by underscoring the nonequilibrium metabolic status of living cell.

description: Pericytes are critical players in vascular development and disease but are not widely studied in the context of cerebral small vessel disease, a vascular condition related to stroke that progressively weakens brain microvessels. Foxf2, a pericyte-expressed gene, is involved in vascular stability and reduced FOXF2 is associated with increased stroke risk and CSVD prevalence. Here, I use a zebrafish foxf2a loss of function mutant as a genetic model of CSVD to show pathological alterations in brain pericytes. Not only are there fewer brain pericytes across the lifespan, but these pericytes also exhibit morphological abnormalities like increased soma size, process length and degeneration. These abnormalities manifest differently in adult brains, and blood vessel defects are evident. I show that embryonic pericyte defects are not the result of decreased pericyte density but a combination of cell-autonomous and non-cell-autonomous effects. A downstream target of foxf2a, loxl2b, is downregulated in foxf2 mutants. While loxl2b mRNA is sufficient to boost brain pericyte numbers, mutants for this gene do not show an obvious phenotype, suggesting a more complicated role. This thesis sheds light on novel lifespan defects in mutant brain pericytes, potentially contributing to vascular destabilization, and opens new avenues for studying genetic forms of human cerebral small vessel disease.

description: From media coverage of transgender celebrities to national discussions of rights for transgender people, transgender and gender non-conforming identities and experiences are more visible than ever. However, visibility doesn’t always equate to inclusion and equity. There is still much to be done and much that social workers can do. Regardless of specialization or area of practice, social workers ought to understand the dynamics of gender, gender identity and expression in order to further assist the transgender community. Because people are at varying stages of the transgender spectrum (from curiosity to exploration to gender reassignment/confirmation), social workers across settings and practices will find themselves working with this community and so should be prepared for their evolving needs. This training is designed to provide information about trans-identities and help attendees develop skills to provide support, treatment and advocacy that is trans-affirming, inclusive and prevents retraumatization.

description: Wetlands, spanning approximately 15 million hectares globally, play a crucial role in supporting diverse ecosystems and sustaining livelihoods, particularly in tropical and subtropical regions. In Africa alone, these vital ecosystems cover over 3.2 million hectares, constituting 19% of the world's wetland coverage. This paper delves into the significance of wetland ecosystems and their associated fisheries, which are lifelines for an estimated 275 million people in developing countries. Traditional activities such as timber and non-timber forest product harvesting, fishing, and fuelwood collection form the cornerstone of livelihoods reliant on wetland resources.

Beyond their economic importance, wetlands serve as essential ecological, cultural, and aesthetic entities. They act as crucial exporters of materials supporting near-shore food webs, including prized commodities such as prawns and shrimp. Additionally, wetlands play a pivotal role in intercepting pollutants, land-derived nutrients, and suspended matter, thereby mitigating the adverse impacts of contaminants on deeper water bodies. Moreover, these ecosystems harbor rich biodiversity, providing habitats for a myriad of fauna, ranging from mammals and fish to crustaceans, reptiles, amphibians, avian species, and various aquatic and terrestrial insects.

Recognizing the multifaceted values of wetlands is imperative for informed conservation and management efforts. Conservation strategies must not only safeguard the ecological integrity of wetland ecosystems but also prioritize the sustainable utilization of their resources to ensure the continued well-being of dependent communities. Integrated approaches that balance ecological preservation with socio-economic development are paramount for achieving resilience and sustainability in wetland management.

This paper underscores the urgent need for collaborative action among policymakers, scientists, practitioners, and local communities to address the myriad challenges facing wetland ecosystems. By fostering dialogue, knowledge exchange, and innovative solutions, stakeholders can forge pathways towards the conservation and sustainable management of wetlands, safeguarding their invaluable contributions to biodiversity conservation, climate resilience, and human well-being
Understanding disturbance, facilitation, and competition for conservation of whitebark pine in the Canadian Rockies
Creators: name: Wong, Carmen Monica
Publisher: name: University of British Columbia
Year: 2012

description: Understanding forest resilience to novel disturbances and how tree interactions will be affected by global change is critical for predicting future forest composition. The widespread decline of the endangered whitebark pine (Pinus albicaulis) in the Canadian Rockies due to non-native white pine blister rust (Cronartium ribicola) and native mountain pine beetle (Dendroctonus ponderosae) and Ips sp. permitted examination of interactions between disturbances and tree responses in high-elevation forests. Disturbance severity was high with 20-90% whitebark pine mortality over 50 years in 16 stands. Basal annual increment (BAI) of whitebark pines prior to mortality from mountain pine beetles declined 46%, but only by 25% for those subsequently killed by blister rust and Ips sp.. Climate-growth relationships suggest blister rust increased sensitivity of whitebark pines to variation in summer precipitation, reducing resistance to beetles. The mortality of whitebark pine was used as an in-situ experiment simulating neighbour removal to test the stress-gradient hypothesis of tree interactions. Facilitation intensity, determined by comparing subalpine fir (Abies lasiocarpa) regeneration around live, top-killed, or dead adult whitebark pines, increased with elevation but depended on benefactor size and neighbourhood density. Large-diameter, top-killed whitebark pines were more facilitative than live trees, indicating thresholds in benefactor size, below which live, healthy trees were facilitators and above which they were competitors. Size thresholds were also found in interactions between adult trees where competition intensity increased between trees of greater diameter differences as indicated in BAI releases of subalpine fir after the death of neighbouring trees. Conversely, the importance of competition relative to other factors influencing growth increased between trees more similar in size and with abiotic stress. My results refine the stress-gradient hypothesis by demonstrating hierarchical influences on tree interactions. The predominant release from competition doubled subalpine fir’s BAI from the landscape average pre- disturbances compensating for the decline predicted by climate-growth relationships. Lack of regeneration and growth release in surviving whitebark pines and an abrupt shift in key variables suggest a regime shift to fir dominance and whitebark pine extirpation. Whitebark pine resilience was higher at sites of low abiotic stress and disturbance severity, relationships useful for conservation.

 reality. This is the case of learning communities which despite being in challenging contexts, have
 been capable of coping with adversities. This study, framed within two bigger research projects
 about Professional learning communities1, focuses on a school located in Spain that has shown an
 inner strength to transform a prior challenging context to another that looks towards learning
 quality and educational equity. In essence, the research developed adopts a single case study
 format, from a reflective biographical-narrative and dialogical perspective. The thematic analysis
 carried out from this case study has found a group of themes that allow us to understand how this
 school is led and organised. Results are related to the capacity of resilience that this school has
 developed to achieve the transformation they were looking for.

description: The last decade has witnessed substantial interest in protocols for transferring information on networks of quantum mechanical objects. A variety of control methods and network topologies have been proposed, on the basis that transfer with perfect fidelity --- i.e. deterministic and without information loss --- is impossible through unmodulated spin chains with more than a few particles. Solving the original problem formulated by Bose [Phys. Rev. Lett. 91, 207901 (2003)], we determine the exact number of qubits in unmodulated chains (with XY Hamiltonian) that permit the transfer with fidelity arbitrarily close to 1, a phenomenon called pretty good state transfer. We prove that this happens if and only if the number of nodes is n=p-1, 2p-1, where p is a prime, or n=2^{m}-1. The result highlights the potential of quantum spin system dynamics for reinterpreting questions about the arithmetic structure of integers, and, in this case, primality.

Kirby exposes a peculiar construction of cosmopolitanism at the root of Grainger’s modes of presenting Delius to US audiences, arguing that by downplaying his European national roots, Delius and his music could be deployed as a “blank canvas” upon which Grainger could superimpose his own “developing racist ideologies.”

description: Storage tanks in the process industry are often filled with hazardous media under atmospheric conditions. Due to heavy rain showers the tank content is cooled down and the system temperature drops significantly. During this process the pressure decreases and condensate forms. It is known that "vacuum" can cause serious damage on storage tanks due to undersized venting devices. To describe the transient storage tank behaviour modelling of  complex  inbreathing  fluid  flow,  heat  transfer,  condensation,  retrograde  gas  states  or  thermodynamic  non-equilibrium  is  needed.  Conservative  sizing  of  protection  devices  for  storage  tanks  is  only  possible  if  the  influencing  phenomena  and  their  couplings  are  well  understood.  The  influence  of  heat  transfer  through film condensation  as  an  example  phenomenon  is  mentioned  by  several  authors  in  science  and  industry,  but  not  included in common models.With  the  new  approach  of  ARTEM  (advanced  reactor  and  storage  tank  emission  model)  phenomena,  like  condensation  or  complex  heat  transfer  will  be  considered  for  transient  vessel  venting.  Experience  and  preparatory  work  have  shown  that  detailed  modelling  with  computational  fluid  dynamic  (CFD)  tools  is  necessary  to  analyse  the  complex  multiscale  phenomena  accurately  and  in  sufficient  detail.  As  a  first  step  towards ARTEM, an analytical parameter study on tank breathing with common sizing models and a CFD study on heat transfer through a tank wall is presented.

description: Complex  phenomena  in  wastewater  systems,  such  as  flow  pattern  in  sewers  and  sediment  transport  could  be  investigated in detail using computational fluid dynamics (CFD). However, it is not easy to find an appropriate CFD model for a specific problem. This paper aims to develop and validate a CFD model to correctly predict the  free-surface turbulent flow passing through a circular pipe.  In this study, the multiphase model Volume of Fluid  (VOF)  of  the  software  Ansys-Fluent was used  to  capture  the  interface  between  air  and  water.  Different  variants of the k-eturbulence model of the RANS group and meshing approaches were investigated. To validate the CFD model, a set-up of an acryl-glass pipe in a closed system was constructed under laboratory conditions. The  centre-plane  velocity  profile  was  used  to  compare  the  CFD  model  results  and  Laser  Doppler  Velocimetry  (LDV)  measurements.  Furthermore,  the  values  of  the  average  velocity  and  shear  stress  from  the  experiments  were compared to the results of the CFD model. The best results were obtained using a Cutcell mesh combined with  the  RNG  k-eturbulence  model.The  validated  model  was  used  to  investigate  the  influence  of  the  bed  roughness  on  the  velocity  and  shear  stress  distribution  in  partially  filled  pipes.  The  velocity  decreases  while  increasing the bed roughness,  however  the shear stress becomes greater over a rough bed than over a smooth bed.
Milton Babbitt’s Glosses on American Jewish Identity

description: Despite the fact that Babbitt claimed to “regard himself as Jewish and did not wish to be in any way evasive about being Jewish,” little scholarship has documented how Babbitt’s Jewish identity influenced his discourse or music. Yet, during the postwar era—a time when many American Jews felt an obligation to reaffirm their Jewish identity—Babbitt frequently employed Jewish themes in his discourse. Mapping the Jewish Exile narrative onto the plight of academic composers, he often draws correspondences between Schoenberg and Moses, America and the Promised Land, and the university and Masada. In this article, I contextualize this aspect of Babbitt’s rhetoric by outlining how his relationship to his Jewish identity evolved over the course of his career: from concessions he made to Princeton’s anti-Semitic policies early in his career to his active participation in conferences devoted to Jewish issues later in his career. I argue that the analogies Babbitt draws between Jewish tradition and his music demonstrate that he, like many American Jews during the period, fashioned his Jewish identity around Jewish individuals and religious beliefs that complemented his secular worldview. Then, I examine the repercussions Babbitt’s constructed Jewish identity had for his music. To this end, I offer an interpretation of three climactic, unsung moments in Glosses (1988). These three un-pitched vocalizations, I argue, not only realize the Jewish tradition wherein God, who in defying definition also resists signification, but also gloss Schoenberg’s musical symbol for YHVH.

description: Introduction: Coronavirus-19 disease (COVID-19) continues to influence the health and quality of life of Canadians to this day, even after recovering from the initial infection itself. Long COVID is a heterogenous and multi-organ disease that captures a range of symptoms that are prevalent months after infection, including persistent breathlessness (dyspnea for >12 weeks post-infection). Hypoxia and inflammation are important potential mechanisms for long COVID that cause endothelial damage and changes to the pulmonary vasculature which may contribute to unexplained dyspnea. Tissue-specific damage can be characterized using fragments of DNA released into the circulation known as cell-free DNA (cfDNA). Importantly, these fragments retain epigenetic information that can be leveraged to determine the tissue of origin as well as disease-specific methylation changes. Objective: To develop a cfDNA methylation assay to characterize cell-specific damage in PVD groups and delimitate the role of PVD in long COVID. Specific Aims: Aim 1: Identify and validate DMRs for pulmonary cell types. Aim 2: Use Nanopore sequencing to find tissue and disease-specific DMRs. Aim 3: Associate levels of DMRs in patients with PVD and long COVID with clinical presentations. Key Results and Significance: We have validated the specificity of endothelial cell and pulmonary tissue DMRs against a tissue panel to quantify cell-specific injury in patient cfDNA. We have also performed Nanopore sequencing of cfDNA from patients with long COVID, Pulmonary Arterial Hypertension (PAH), and Chronic Thromboembolic Pulmonary Hypertension (CTEPH). We have used this data to demonstrate disease-specific methylation patterning. Our work has also highlighted some gaps to address in order to use the advantages of a PCR-free, Bisulfite-conversion-free and absolute quantification of cfDNA methylation via Nanopore sequencing.

description: We discuss quantum fluctuations of the interface between a superfluid and a Mott-insulating state of ultracold atoms in a trap. The fluctuations of the boundary are due to a new type of surface modes, whose spectrum is similar (but not identical) to classical capillary waves. The corresponding quantum capillary length sets the scale for the penetration of the superfluid into the Mott-insulating regime by the proximity effect and may be on the order of several lattice spacings. It determines the typical magnitude of the interface width due to quantum fluctuations, which may be inferred from single site imaging of ultracold atoms in an optical lattice.

description: This thesis project celebrates 2SLGBTQIA+ Bangladeshi people. I am a Bangladeshi person and a Canadian citizen who is part of the 2SLGBTQIA+ community. This thesis consists of three painted portraits titled Radha is Crowned King that portray Bharatnatyam dance positions which convey the love described by famous Bengali poet Kazi Nazrul Islam about the deity partners Radha and Krishna. Through culturally recognizable and significant gestures, the figures swap genders. Through this gender swap, the paintings represent diversity in gender that one can embody. South Asian artists who utilize storytelling to share 2SLGBTQIA+ experiences, have informed the way in which my work resists dehumanization of Bangladeshi LGBTQIA+ people. Artists Vivek Shraya, Salman Toor, Ruhul Abdin, and Tara Asgar are telling queer stories through their visual art and writing. Kazi Nazrul Islam wrote the poem Shoke She Hari Kemon Bol that is about being passionately in love, and that inspired this thesis. Radha is Crowned King confronts the audience with fluidity of gender adding to this collective depth of 2SLGBTQIA+ storytelling, through my queer truth and narrative. This work consists of painting which allows for the creation and illustration of a world where gender hybridity and fluidity exists and is celebrated despite discrimination in the real world. This work is informed by cultural understanding and familial knowledge. This work is also informed by the book Queering Autoethnography by Stacy Holman Jones and Anne M. Harris, and is invigorated by the historical existence of LGBTQIA+ Bangladeshi people. Within cis-heteronormative cultures there is dehumanization and discrimination of LGBTQIA+ Bangladeshi people. The significance of this work is to rejoice with and for 2SLGBTQIA+ people and honor our existence and beauty. My work functions to share a narrative of 2SLGBTQIA+ acceptance. It mediates between 2SLGBTQIA+ people and the Bangladeshi masses, contributing to fostering a stronger community that is peaceful and accepting.

Blacks--Social life and customs

description: Among the musical representations of Deep South African American life circulating in the 1930s and early 1940s, Ellington’s extended composition Black, Brown, and Beige and Zora Neale Hurston’s staged revue The Great Day stand out for their shared emphasis on the laboring body. This emphasis, I argue, countervailed predominant representations produced in two important spheres of artistic activity at the time. The first, Tin Pan Alley, had inherited much from the legacy of nineteenth-century blackface minstrel theater and tended to present Southern plantation life through nostalgic, bucolic tableaus and through playful “naturally rhythmic” dancing black bodies. The second, intellectuals associated with the Harlem Renaissance, cast the concert spiritual as the music best suited to put black cultural actors on equal footing with their white counterparts, positioning the “soul” as the bearer of African American culture, thus downplaying the role of the body.

Building on works from Cedric Robinson and Raymond Williams, this article highlights the ideological work that goes into naturalizing ideas of race and space. In the 1930s and 1940s this ideological work could be seen in what Ellington labeled “the Dixie Chamber of Commerce dream picture of the South.” Through Ellington’s poetry and Hurston’s critical essays, I show the intent of these artists to reimagine the Deep South landscape in ways that highlight the contribution of black labor. Then, through an analysis of Ellington’s music and Hurston’s staging of folkloric songs, I demonstrate the specific ways that each artist went about realizing this intent.

description: By extending our general spin-current model to non-centrosymmetric spin dimers and performing density functional calculations, we investigate the causes for the helical magnetic order and the origin of the giant ferroelectric polarization of CaMn7O12. The giant ferroelectric polarization is proposed to be caused by the symmetric exchange striction due to the canting of the Mn4+ spin arising from its strong Dzyaloshinskii-Moriya (DM) interaction. Our study suggests that CaMn7O12 may exhibit a novel magnetoelectric coupling mechanism in which the magnitude of the polarization is governed by the exchange striction, but the direction of the polarization by the chirality of the helical magnetic order.

description: Part I of this two-part article addressed the difficulties experienced by Australian higher education providers, namely universities, with respect to the implementation of learning outcomes and graduate attributes, and the potential legal consequences institutions may face from affected stakeholders if they are unable to produce convincing evidence demonstrating the integration of the learning outcomes and graduate attributes. Part II presents measures higher education providers can implement to mitigate their potential legal liability. The measures presented in this article are specifically designed to assist higher education providers to discharge their legal obligations and produce convincing evidence demonstrating the integration of their promoted learning outcomes and graduate attributes. Given that research has suggested that effective implementation of learning outcomes and graduate attributes is largely dependent on academic staff, the measures presented in this paper are centred on motivating and building confidence in academic staff to foster the development of learning outcomes and graduate attributes through their teaching and assessment practices.

description: COVID-19 has caused more than 7 million deaths, and according to the World Health Organization, it continues to result in more than 1000 reported deaths per week at the time of this writing. Therefore, it is crucial to understand the immune response to COVID-19 since the virus has the potential to become endemic, like influenza A. Natural killer (NK) cells are essential for immune defence against viral infections and play a critical role in COVID-19. While it is well documented that infected patients have a reduction in lymphocytes and NK cells, gaps in knowledge exist regarding the function of NK cells. To study the function of NK cells in COVID-19 patients, peripheral blood was obtained from patients admitted to the medical (non-ICU) wards at the Foothills Medical Centre with a positive COVID-19 test. I demonstrated a decrease in the mature cytotoxic subset of NK cells within the peripheral blood of patients hospitalized with COVID-19. I also observed a notable decrease in the cytotoxic function of NK cells against tumour targets. I examined the sequence of events within NK cells that lead to killing in a stepwise manner. I found reductions in the intracellular levels of effector molecules, the degranulation of cytotoxic granules, and the extracellular concentrations of released effector molecules. I identified alterations in intracellular granule trafficking required to position the granules for release. I found alterations in the expression of multiple NK cell receptors, suggesting inhibitory signalling. Additionally, males with COVID-19 showed more pronounced NK cell defects than healthy males, which may partly be due to receptor expressions. My findings highlight defects in cytolytic effector molecules, granule trafficking and release, and increased expression of inhibitory receptors in hospitalized COVID-19 patients, in addition to a sex difference in cytolytic function, which contributes to defective NK cell function in COVID-19.

description: In the early morning hours after the July 15, 2016 Turkish military coup, Turkish President Recep Tayyıp Erdoğan FaceTimed in to CNNTürk to issue an apparently desperate call for Turkish citizens to occupy city squares and “defend democracy.” Erdoğan’s call was loudly repeated by Islamic calls to prayer from muezzins synchronized nationwide via text message. Hearing these calls, thousands of Turks ventured out and collectively reclaimed urban streets and squares for Erdoğan’s government. This paper examines the process by which Islamic calls to prayer forged Turkish citizens into a unisonous body that claimed and transformed secular urban spaces, initiating an epochal neo-Ottoman shift in Turkish politics. I engage with this process via a hybrid virtual-physical ethnographic site derived from coup resistance, treating YouTube videos and contemporary Turkish media as both windows into on-the-ground resistance and sites at which Turks negotiate their political subjectivity. To unpack the role of sacred sound and affective embodiment in leading coup resistance and transforming space (Hirschkind 2006; Massey 2005; Thrift 2009), I employ Turino’s theories of Peircean semiotics and participatory music making. I argue that Islamic calls to prayer-led resistance not only turns the tables on the repressive sonic regimes of Republican Turkey, but also challenges understanding of twenty-first century nationalisms rising in the twittersphere. In the early hours of July 16, 2016, Facetime and text message laid the foundations, but it was Islamic calls to prayer resounding in streets and squares that forged citizens into a unisonous body capable of transforming secular urban space and the future of Turkish politics.
N-Jettiness as a probe of nuclear dynamics

description: We propose the use of N-jettiness (τ_N), a global event shape variable, as a probe of nuclear dynamics in lepton-nucleus collisions. It characterizes the amount of soft radiation between the jet and nuclear beam directions. We write down the factorization for the 1-jettiness ($τ_1$) distribution for the production of a single hard jet (J) in lepton-nucleus collisions: \ell+A(P) \to J(P_{J})+X. Each nuclear target gives rise to a unique pattern radiation, determined by nuclear dynamics, that can be quantified by the τ_1-distribution. Up to power corrections, the τ_1-distribution allows for a direct measurement of the nuclear PDFs. Additional nuclear-dependent effects will be dominated through power corrections of size $\sim Q_s^2(A)/(P_{JT}τ_1)$ where $Q_s(A)$ is a dynamical scale sensitive to nuclear medium effects. Such nuclear-dependent effects and the dependence of Q_s(A) on the nuclear atomic number $A$ can be probed through a dedicated program of precision measurements of τ_1-distributions for various nuclei and kinematics. We give numerical results for the 1-jettiness distribution for the simplest case of a proton target at next-to-leading-log accuracy.

description: A majority of methods from dynamical systems analysis, especially those in applied settings, rely on Poincaré's geometric picture that focuses on "dynamics of states". While this picture has fueled our field for a century, it has shown difficulties in handling high-dimensional, ill-described, and uncertain systems, which are more and more common in engineered systems design and analysis of "big data" measurements. This overview article presents an alternative framework for dynamical systems, based on the "dynamics of observables" picture. The central object is the Koopman operator: an infinite-dimensional, linear operator that is nonetheless capable of capturing the full nonlinear dynamics. The first goal of this paper is to make it clear how methods that appeared in different papers and contexts all relate to each other through spectral properties of the Koopman operator. The second goal is to present these methods in a concise manner in an effort to make the framework accessible to researchers who would like to apply them, but also, expand and improve them. Finally, we aim to provide a road map through the literature where each of the topics was described in detail. We describe three main concepts: Koopman mode analysis, Koopman eigenquotients, and continuous indicators of ergodicity. For each concept we provide a summary of theoretical concepts required to define and study them, numerical methods that have been developed for their analysis, and, when possible, applications that made use of them. The Koopman framework is showing potential for crossing over from academic and theoretical use to industrial practice. Therefore, the paper highlights its strengths, in applied and numerical contexts. Additionally, we point out areas where an additional research push is needed before the approach is adopted as an off-the-shelf framework for analysis and design.

description: Many more survivors of childhood cancer are surviving and thriving today. In Canada, there are approximately 30,000 survivors, and treatment advances have helped to improve survival rates. However, survivors still face challenges that arise after treatment completion. Examples of challenges include difficulties with behavioral or emotional regulation as well as impaired attention and cognitive functioning. These challenges affect broader functional outcomes such as lower adaptive functioning and lower rates of completing higher education. Thus, in this thesis I aimed to summarize the current literature in adaptive functioning and educational outcomes (i.e., reading, writing, and math) and to examine these factors in survivors of childhood cancer (SCC). Chapter 1 of my thesis is a brief introduction about childhood cancer, education achievement, and the factors that affect educational achievement in SCC. Chapter 2 provides a literature review on pediatric acute lymphoblastic leukemia (ALL) and non-central nervous system solid tumors (non-CNS ST), late effects of cancer treatment, educational outcomes and adaptive functioning in ALL, non-CNS ST, and brain tumors (BT). Chapters 3 and 4 of my thesis have been prepared for publication and address four primary aims across these manuscripts. Chapter 3 aimed to examine group differences in adaptive functioning among pediatric survivors of ALL, non-CNS ST, BT, and healthy controls (HC). The second aim of this manuscript was to explore whether age at diagnosis, male sex, and lower socioeconomic status predicted lower adaptive functioning. Chapter 4 aimed to examine group differences on the Wide Range Achievement Test (WRAT-5) between survivors of ALL and non-CNS ST and to examine the association between conceptual skills and WRAT-5 outcomes.

description: Morphological data sets are misleading in salamander (Caudata) phylogeny due to the relative homoplasy of the dermal skull observed in paedomorphic forms, leading to the trend of excluding morphology when exploring questions of salamander phylogeny. Investigations in caecilians (Gymnophiona) have demonstrated that the inclusion of braincase morphology can rescue morphological phylogenetic analyses and produce topologies congruent with molecular data sets. We scanned 28 species (25 genera) of salamander, representing all 10 families, with high-resolution micro-computed tomography to investigate braincase variation. We describe the morphology of the braincase for all 10 families and distinguish between paedomorphic and metamorphic morphologies. Our results demonstrate a general uniformity amongst metamorphic species with variation largely restricted to the occipito-otic region. A greater range of variation is observed within paedomorphic forms than would be expected when considering the homoplasy of the dermal skull. Obligate paedomorphic forms demonstrate considerably more variation in the anterior braincase than do facultative paedomorphs, which we suggest is evidence of a greater complexity in the evolution and development of these forms than neoteny alone would produce. This raises the question of character independence within morphological data sets and warrants further investigation into the correlation of other characters before morphological data are omitted.
