Mediation of the Oral Microbiome Between Obesity and Oral Health in Chicago Children
Creators: name: Whyms, Pamela S
Publisher: name: University of Illinois at Chicago
Year: 2023

description: The dysbiosis or disruption of the oral microbiome can have serious negative health effects in the oral cavity. Dysbiosis can either refer to a change of the composition of the species present in the microbiome, or a change in the genes that are expressed in the microbiota. Dysbiosis is often associated with gingival inflammation, which can cause damage to dental tissue. Inflammation can be an indication of dysbiosis and/or systemic inflammation throughout the body due to obesity. Because of the negative health effects of dysbiosis and gingival inflammation, it’s important to understand how this cycle begins and what occurs during dysbiosis. Many studies on this topic focus on adults. However, childhood obesity is increasing in the U.S. which is also likely causing a rise in systemic inflammation among children as well. Children’s diets are also increasing in sugar and carbohydrates, which can lead to dysbiosis and gingival disease. Therefore, the primary aim of this dissertation was to explore whether specific species in the oral microbiome mediate the relationship between obesity and gingival inflammation among children in Chicago, who are more likely to have obesity compared to national averages. If individual species acted as mediators, they may cause their own level of inflammation and exacerbate poor gingival health. Patients aged 10-12 from UIC’s Pediatric Dental Clinic were recruited for this study. Each child provided dietary information through a Food Frequency Questionnaire (FFQ). Gingival swabs were collected to sequence their oral microbiome. And demographic information such as race, ethnicity, and household income were collected in a survey filled out by the parents of the patients. I identified Tannerella forsythia as a significant mediator in this sample, which was important because its associated with inflammation and periodontal disease. The mediation of T. forsythia between obesity and gingival inflammation may suggest that some of the children in this study are at the precipice of further oral microbiome dysbiosis which could lead to a cascade of oral health problems. I propose that children with obesity may be experiencing the combined effects of obesity-mediated systemic inflammation and oral microbiome-derived local inflammation.

Asian Public Space since 1945: From Mao to the Mall and Beyond
Creators: name: Shane, David Grahame
Publisher: name: FOOTPRINT
Year: 2013

description: The form of the city and its public spaces are changing in Asia. This short survey tracks the retreat of the European imperial space systems as Asian nations gained independence and the multi-centered, global corporate system of public space-making that emerged from 1990-2008. It also tracks the appearance of a specifically Asian rural-urban space-making system of urban villages that has emerged as a long cultural continuity in and around Asian cities. Four models of urban space are examined: Metropolis, Megalopolis, Fragmented Metropolis, and Megacity/Metacity. All are simultaneously present in the Asian city, forming parallel timelines weaving around each other. After the 2008 crash there is reason to pause and re-evaluate this highly successful, emerging Asian urban system and its public spaces, especially in view of the likely implications of energy supplies and climate change on key Asian cities located in coastal and river valley situations.

description: We propose an accurate clocked single-spin source for ac-spintronic applications. Our device consists of a superconducting island covered by a ferromagnetic insulator layer through which it is coupled to superconducting leads. Single-particle transfer relies on the energy gaps and the island's charging energy, and is enabled by a bias and a time-periodic gate voltage. Accurate spin transfer is achieved by the ferromagnetic insulator layer which polarizes the island, provides spin-selective tunneling barriers and improves the precision by suppressing Andreev reflection. We analyze realistic material combinations and experimental requirements which allow for a clocked spin current in the MHz regime.
Assessment of Muscle Stiffness, Electromechanical Delay, and Muscle Extensibility over the Course of the Menstrual Cycle
Creators: name: Pate, Megan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: Anterior cruciate ligament injuries are more common in females than in males. Research has failed to isolate a cause for this bias. Hormones have been implicated in increased injury rates, increased ligamentous laxity, decreased stiffness, and increased electro-mechanical delay. We compared active and passive muscle stiffness, electromechanical delay, and extensibility of the knee flexor group between menses and ovulation in eumenorrheic women. No significant differences in active and passive muscle stiffness, electromechanical delay, or extensibility of the knee flexor group were measured between menses and ovulation. Menstrual cycle phase may not have an effect on active and passive muscle stiffness, electromechanical delay, or extensibility. Therefore, increased anterior cruciate ligament injury rates in females may not be caused by hormonal changes in muscle stiffness.

description: The classical discrete time model of proportional transaction costs relies on the assumption that a feasible portfolio process has solvent increments at each step. We extend this setting in two directions, allowing for convex transaction costs and assuming that increments of the portfolio process belong to the sum of a solvency set and a family of multivariate acceptable positions, e.g. with respect to a dynamic risk measure. We describe the sets of superhedging prices, formulate several no (risk) arbitrage conditions and explore connections between them. In the special case when multivariate positions are converted into a single fixed asset, our framework turns into the no good deals setting. However, in general, the possibilities of assessing the risk with respect to any asset or a basket of the assets lead to a decrease of superhedging prices and the no arbitrage conditions become stronger. The mathematical technique relies on results for unbounded and possibly non-closed random sets in Euclidean space.

description: We study multiparticle production in the unbroken $(3+1)$-dimensional $λϕ^4$ theory using the semiclassical method of singular solutions. We show that the probabilities of these processes are exponentially suppressed in terms of a small coupling constant $λ\ll 1$ if the multiplicity of the final state is large: $n \gg 1$. At $ n \ll λ^{-1}$ the probabilities agree with well-known perturbative results. At $ n \gg λ^{-1}$ they are dominated by loop effects and decrease exponentially with $n$, as we show for the first time.

description: With the advancement in the digital camera technology, the use of high resolution images and videos has been widespread in the modern society. In particular, image and video frame registration is frequently applied in computer graphics and film production. However, conventional registration approaches usually require long computational time for high resolution images and video frames. This hinders the application of the registration approaches in the modern industries. In this work, we first propose a new image representation method to accelerate the registration process by triangulating the images effectively. For each high resolution image or video frame, we compute an optimal coarse triangulation which captures the important features of the image. Then, we apply a surface registration algorithm to obtain a registration map which is used to compute the registration of the high resolution image. Experimental results suggest that our overall algorithm is efficient and capable to achieve a high compression rate while the accuracy of the registration is well retained when compared with the conventional grid-based approach. Also, the computational time of the registration is significantly reduced using our triangulation-based approach.
Science for Architecture: Designing Architectural Research in Post-War Sweden
Creators: name: Rosenberg, Frida
Publisher: name: FOOTPRINT
Year: 2012

description: How did architectural research in Sweden become scientific in its approach rather than artistic, as architecture education in the post-war period was primarily influenced by the Bauhaus pedagogy? Via the American Bauhaus pedagogical developments taking place at the IIT and the GSD, Swedish architecture education adopted the artistic ‘learning by doing’ approach. The most interesting structure signifying this was a permanent exhibition of building materials located in the foreground of the 1957 KTH architecture school. When the new KTH architecture school was completed its architecture illustrated another image: that of the new architecture curriculum, A68, put into practice the same year as the building was designed. A68 reorganized architecture education and put more focus on environmental studies and building function analysis. The new curriculum included the subjects Formlära, Design Principles, and Byggnadsfunktionslära, Building Function Analysis, which were technical in their approach of using empirical research. As a result, the 1969 KTH architecture building included a laboratory for testing technical problems in air-conditioned spaces as well as a laboratory for testing acoustics. The 1961 LTH architecture building included a full-scale-laboratory where studies were directed by Carin Boalt, the first female professor at a technical university.

description: In the hydraulic fracturing of natural rocks, understanding and predicting crack penetrations into the neighboring layers is crucial and relevant in terms of cost-efficiency in engineering and environmental protection. This study constitutes a phase field framework to examine hydraulic fracture propagation in naturally-layered porous media. Biot's poroelasticity theory is used to couple the displacement and flow field, while a phase field method helps characterize fracture growth behavior. Additional fracture criteria are not required and fracture propagation is governed by the equation of phase field evolution. Thus, penetration criteria are not required when hydraulic fractures reach the material interfaces. The phase field method is implemented within a staggered scheme that sequentially solves the displacement, phase field, and fluid pressure. We consider the soft-to-stiff and the stiff-to-soft configurations, where the layer interface exhibits different inclination angles $θ$. Penetration, singly-deflected, and doubly-deflected fracture scenarios can be predicted by our simulations. In the soft-to-stiff configuration, $θ=0^\circ$ exhibits penetration or symmetrical doubly-deflected scenarios, and $θ=15^\circ$ exhibits singly-deflected or asymmetric doubly-deflected scenarios. Only the singly-deflected scenario is obtained for $θ=30^\circ$. In the stiff-to-soft configuration, only the penetration scenario is obtained with widening fractures when hydraulic fractures penetrate into the soft layer.

description: We present the results of the first complete unbaised survey of the Galactic Plane for 6035-MHz excited-state hydroxyl masers undertaken as part of the Methanol Multibeam Survey. These observations cover the Galactic longitude ranges $186^{\circ}< l < 60^{\circ}$ including the Galactic Centre. We report the detection of 127 excited-state hydroxyl masers within the survey region, 47 being new sources. The positions of new detections were determined from interferometric observations with the Australia Telescope Compact Array. We discuss the association of 6035-MHz masers in our survey with the 6668-MHz masers from the MMB Survey, finding 37 likely methanol-excited-state hydroxyl masers maser pairs with physical separations of <=0.03pc and 55 pairings separated by <=0.1pc. Using these we calculate for the first time an excited-state hydroxyl maser life time of between 3.3x10^3 and 8.3x10^3 years. We also discuss the variability of the 6035-MHz masers and detection rates of counterpart 6030-MHz excited-state hydroxyl masers (28% of our sample having detection at both frequencies).

John Hejduk’s Pursuit of an Architectural Ethos
Creators: name: Søberg, Martin
Publisher: name: FOOTPRINT
Year: 2012

description: Reflected, artistic practices and design-based research are drastically expanding fields within architectural academia. However, the interest in uniting theory and practice is not entirely new. Just a few decades ago, before a ‘death of theory’ was proclaimed, questions of architectural epistemology, of the language(s) of architecture, were indeed of profound interest to the discipline. This essay returns to and examines the investigatory practices of John Hejduk in an attempt to identify a poetic method asserting difference through repetition and primarily grounded in the medium of architectural drawing; a method which, when approached on a more general and conceptual level, might even have the potential to inform design-based architectural research today. The author argues that the conceptual framework of such a method is not a theoretical pursuit of logos, but more a matter of character – an embracing pursuit of an architectural ethos.

description: We consider the problem of scale detection in images where a region of interest is present together with a measurement tool (e.g. a ruler). For the segmentation part, we focus on the graph based method by Flenner and Bertozzi which reinterprets classical continuous Ginzburg-Landau minimisation models in a totally discrete framework. To overcome the numerical difficulties due to the large size of the images considered we use matrix completion and splitting techniques. The scale on the measurement tool is detected via a Hough transform based algorithm. The method is then applied to some measurement tasks arising in real-world applications such as zoology, medicine and archaeology.
Effects of individualized prescriptive exercise program on selected fitness parameters and fatigue of acute leukemia patients undergoing treatment
Creators: name: Sanzhar, Anna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: Although standard treatment improves survival for acute leukemia patients, development of treatment side effects is of major concern. Therefore, it is important to explore the impact of adjunct therapies, such as exercise, in mitigating treatment-related side effects. The primary purpose of this study was to examine the effects of exercise on selected fitness parameters and fatigue in acute leukemia patients undergoing treatment. A secondary purpose was to examine the relationship between changes in selected fitness parameters and fatigue. Ten patients with acute leukemia participated in this study. Exercise protocol included aerobic, resistance, and flexibility performed 3 times/week for 6 weeks. Significant changes in cardiovascular endurance and overall fatigue (p = 0.009 for both), with no changes in overall muscular endurance (p= 0.715) were observed. In conclusion, the results of this study suggest that administration of exercise during the leukemia treatment promotes improvement of cardiovascular endurance, maintenance of muscular endurance and reduction in fatigue levels.
Architecture’s Awaking from Correlationist Slumber: On Transdisciplinarity and Disciplinary Specificity
Creators: name: Radman, Andrej
Publisher: name: FOOTPRINT
Year: 2012

description: Perception cannot be considered independently of the environment since it is defined as an evolved adaptive and constructive relation between the life-form and its milieu. Unfortunately, experimental psychology research has relied overwhelmingly on object perception, rather than environment perception, with the findings of the former providing the basis for understanding the latter. Architectural research continues to suffer from this fallacy. Furthermore, to separate the ‘cultural’ from the ‘natural’ environment – as if there were a world of mental and a world of material products – is a fatal mistake. There is only one world. The paper explores J.J. Gibson’s unwitting affiliation with Deleuze. The most notable point of convergence between the two thinkers is their more or less overt theory of ‘passive synthesis’ of perception with which they vehemently oppose, or better yet complement, the active synthesis of representation.

description: The Glasgow Haskell Compiler is known for its feature-laden runtime system (RTS), which includes lightweight threads, asynchronous exceptions, and a slew of other features. Their combination is powerful enough that a programmer may complete the same task in many different ways -- some more advisable than others. We present a user-accessible actor framework hidden in plain sight within the RTS and demonstrate it on a classic example from the distributed systems literature. We then extend both the framework and example to the realm of dynamic types. Finally, we raise questions about how RTS features intersect and possibly subsume one another, and suggest that GHC can guide good practice by constraining the use of some features.

The Tradition of Spatial Writing: The Case of the Palindrome in between Literature and Architecture
Creators: name: Varsamis, Sotirios
Publisher: name: FOOTPRINT
Year: 2012

description: In this work I define as spatial writing a kind of writing that could be expressed spatially in text and textually in architecture and that includes examples from both text and buildings. In that sense spatial writing is related not only to literary theory but also to architecture, architectural writing or ‘architecture writing’. In the first part of my paper I outline very briefly the tradition of spatial writing in literary theory, but the main focus is on how text is treated spatially and architecturally within such a theory. In the second part I focus on the palindrome as a specific kind of spatial writing and examine how its geometric poetic form stands in between the disciplines of literature and architecture. From the two examples I study the first is taken from literature and is a palindromic poetic composition from a 1745 pamphlet entitled Coelum Orbis Teutonici, and the second from architecture and looks at palindrome’s use as inscriptions at fountains and thresholds.

description: We consider the consequence of nonreciprocity in near-field heat transfer by studying systems consisting of magneto-optical nanoparticles.We demonstrate that, in thermal equilibrium, a nonreciprocal many-body system in heat transfer can support a persistent directional heat current, without violating the second law of thermodynamics. Such a persistent directional heat current cannot occur in reciprocal systems, and can only arise in many-body systems in heat transfer. The use of nonreciprocity therefore points to a new regime of near-field heat transfer for the control of heat flow in the nanoscale.

La Défense / Zone B (1953-91): Light and Shadows of the French Welfare State
Creators: name: Chabard, Pierre
Publisher: name: FOOTPRINT
Year: 2011

description: Planned as early as 1958 by the Etablissement Public d’Aménagement de La Défense (EPAD, the first such agency in France), the business district of La Défense is a typical urban result of the French version of the welfare state: centralism, modernism, alliance between public and private elites. But with its vertical skyline, this district – called Zone A – constitutes only a small part of the operational sector of the EPAD; the other part, Zone B, coincides with the northern part of the city of Nanterre. In the shadows of the crystalline skyscrapers of La Défense, Zone B was not only a kind of ‘back-office’ of the business district, but also an urban laboratory for public housing ‘paved with good intentions’. From the slab projects of Le Corbusier and his epigones to the urban compositions of postmodern architects, along the proliferating textures of Jacques Kalisz, or the humanized ‘grands ensembles’ of Emile Aillaud, the many EPAD projects for Zone B, built or not, constitute a complete collection that documents the evolution of the ‘architecture urbaine’ from the mid 1950s to the turn of the 1990s.

description: This paper addresses the attitude tracking of a rigid body using a quaternion description. Global finite-time attitude controllers are designed with three types of measurements, namely, full states, attitude plus constant-biased angular velocity, and attitude only. In all three scenarios hybrid control techniques are utilized to overcome the well-known topological constraint on the attitude manifold, while coupled nonsmooth feedback inputs are designed via homogeneous theory to achieve finite-time stability. Specially, a finite-time bias observer is derived in the second scenario and a quaternion filter is constructed to provide damping in the absence of velocity feedback. The proposed methods ensure bounded control torques a priori and, in particular, include several existing attitude controllers as special cases.

The Odd One Out? Revisiting the Belgian Welfare State
Creators: name: Wagenaar, Cor
Publisher: name: FOOTPRINT
Year: 2011

description: Michael Ryckewaert publication Building the Economic Backbone of the Belgian Welfare State. Infrastructure, planning and architecture 1945-1973 describes the evolution of the welfare state and Belgium, more specifically its spatial characteristics. This by now historical socio-political model had decidedly collectivist traits, culminating in the provision of social security networks and a vast expansion of the public domain. If collectivism was one of the key elements of the welfare state, the absence of centralized planning appears to make the Belgian variant somewhat problematic. Whereas in countries like the Netherlands, Germany and France, modernism became the house style of the welfare state, thanks to the massive investments in public housing, this did not happen in Belgium. Here, the De Taeye Act of 1948 sponsored the construction of individual, detached houses; not surprisingly, most clients preferred traditional architecture and refrained from modern experiments. Industrial parks, office buildings and shops, on the other hand, developed into the cornerstones of Belgian modern architecture after 1945. Both the low-density sprawl and the industrial parks depend heavily on the use of the car, which was accommodated by the construction of a network of highways.

description: We propose in this paper the Security Policy Language (SePL), which is a formal language for capturing and integrating distributed security policies. The syntax of SePL includes several operators for the integration of policies and it is endowed with a denotational semantics that is a generic semantics, i.e., which is independent of any evaluation environment. We prove the completeness of SePL with respect to sets theory. Furthermore, we provide a formalization of a subset of the eXtensible Access Control Markup Language (XACML), which is the well-known standard informal specification language of Web security policies. We provide also a semantics for XACML policy combining algorithms.

The Multiple Modernities of Sweden
Creators: name: Gosseye, Janina
Publisher: name: FOOTPRINT
Year: 2011

description: This article reviews the book Swedish Modernism. Architecture, Consumption and the Welfare State, edited by Helena Mattsson and Sven-Olov Wallenstein. In this volume, the editors plea for the construction of ‘multiple modernities’, following which a more diversified understanding of the European welfare state can be constructed. Through twelve contributions by a group of international scholars, Mattsson and Wallenstein aspire to initiate the construction of an emblematic Swedish modernism. The book offers an intricate and diversified reading of the history of the Swedish Folkhemmet, including political history, social sciences and media studies. When it comes to the built environment, however, the volume focuses largely on the home, with a few excursions to exhibition spaces and into corporate culture. In this volume, Mattsson and Wallenstein answer many questions, but raise an equal amount of new questions and thus leave the reader wanting more, as any good book should.

description: Recently, a novel approach using surficial CO2 efflux surveys has been used to delineate hydrocarbon source zones in contaminated aquifers and provide estimates of hydrocarbon biodegradation rates. This approach requires accurately distinguishing between petroleum–derived CO2 respiration and background natural soil respiration. Radiocarbon can be used to distinguish 14C–depleted CO2 of hydrocarbon sources from 14C–enriched CO2 of natural soil respiration to quantify the contribution of each source to total CO2 efflux. In this study radiocarbon was sampled from soil gas monitoring wells, soil gas probes, static chambers and dynamic closed chambers during CO2 efflux studies. Isotopic corrections for quantifying contribution of petroleum–derived CO2 efflux to total soil respiration using these methods are compared at a historical pipeline rupture site in Bemidji, MN and a de–commissioned oil refinery. Results confirmed that survey CO2 efflux measurements can be used to delineate subsurface contaminant source zones and the study showed that radiocarbon obtained from static chambers and soil probe methods give large CO2 sample yields that provide representative contaminant CO2 efflux measurements.

description: Colmez conjectured a product formula for periods of abelian varieties over number fields with complex multiplication and proved it in some cases. His conjecture is equivalent to a formula for the Faltings height of CM abelian varieties in terms of the logarithmic derivatives at $s=0$ of certain Artin $L$-functions. In a series of articles we investigate the analog of Colmez's theory in the arithmetic of function fields. There abelian varieties are replaced by Drinfeld modules and their higher dimensional generalizations, so-called $A$-motives. In the present article we prove the product formula for the Carlitz module and we compute the valuations of the periods of a CM $A$-motive at all finite places in terms of Artin $L$-series. The latter is achieved by investigating the local shtukas associated with the $A$-motive.

description: Prostaglandin E2 (PGE2), a metabolite of arachidonic acid, plays a role in water and sodium reabsorption in the collecting duct of the kidney. The collecting duct is responsible for the fine tuning of water and electrolytes. Only a small fraction of the filtered water and sodium is reabsorbed in the collecting duct, a fraction crucial to the regulation of water and electrolyte balance. This current study addresses the role of EP1, one of four PGE2 receptors, in the collecting duct. It is well documented that PGE2 inhibits sodium and water reabsorption in the collecting duct, however the exact mechanism is still debated. To determine whether the EP1 receptor mitigates AngII renal effects, an in vivo study was performed with EP1-/- mice. Global EP1-/- knockout mice were crossed with a renin overexpressing mouse line (herein denoted as “Ren”) and subjected to a high salt (HS) and low salt (LS) diet. Ren mice displayed an 11mmHg increase in systolic blood pressure (BP) on a HS diet and a decrease in BP of 14mmHg on a LS diet compared to the normal salt (NS) diet. Ren EP1-/- mice did not display a significant increase or decrease in BP on a HS or LS diet. On a LS diet, Ren EP1-/- displayed a drop in urine osmolarity (1641 mOsm/ kgH2O) vs. wild type (WT) mice (2107 mOsm/ kgH2O), consistent with increased sodium reabsorption. Narrowing in on the collecting duct, Ren EP1-/- mice had enhanced αENaC levels compared to Ren mice. In ex vivo microperfusion experiments, EP1-/- tubules show no response to PGE2 in the presence of AVP, whereas PGE2 inhibits AVP induced water reabsorption in WT mice. An increase in αENaC membrane accumulation due to EP1 gene ablation results in increased sodium reabsorption subsequently leading to a rise in BP. This contributes to the lack of salt sensitivity in EP1-/- mice. Overall, the EP1 receptor in the collecting duct represents a potential therapeutic target for the treatment of hypertension.
The Ruins of the British Welfare State
Creators: name: Kaminer, Tahl
Publisher: name: FOOTPRINT

description: The subjects of Owen Hatherley’s A Guide to the New Ruins of Great Britain are architecture and urban development. The book addresses also some broader cultural, political and economic references, as well as personal anecdotes and memories. It includes many encounters with the remnants of the British welfare state. As an extension to his blog postings and a sequel of sorts to his previous Militant Modernism, Hatherley’s antagonist here is the semi-official architecture of New Labour, which he terms ‘pseudomodernism’: an unimaginative, inferior, and, in its own specific way, also tacky architecture of white stucco, steel and glass. He attacks the Faustian bargain of Richard Rogers and his allies with neoliberalism, a pact that produces a modernism devoid of social content, reflected by the unimaginative, speculation-driven architectural design. While Hatherley produces the promised indictment of recent British architecture, the book is, at the end of the day, primarily a eulogy to the disappearing postwar architecture he so evidently loves.

Women's Self-Management of Arm Morbidity After Breast Cancer: A Secondary Data Analysis
Creators: name: Samuel, Vicky Rosine

Subjects: Self-management

Breast Cancer

description: Background: Arm morbidity continues to impact the lives of many breast cancer survivors long after acute treatments are completed. The most debilitating symptoms of arm morbidity are pain, lymphedema and limitation with range of motion (ROM). As a chronic condition, management of arm morbidity symptoms requires survivors to engage in self-management practices that alleviate symptoms. Objective: To explore self-management practices performed by breast cancer survivors, and the treatments women receive from healthcare practitioners in managing symptoms of arm morbidity. Methods: A secondary analysis of quantitative and qualitative data was undertaken. A descriptive correlational design was used to analyze data from breast cancer survivors (N = 740). Logistic regression identified variables related to self-management that were associated with pain, lymphedema and ROM limitations. A descriptive qualitative design was used to analyze data from a subset of participants (n = 40). Inductive content analysis approach was applied to develop codes, categories and themes related to how women self-manage arm morbidity symptoms and the treatments they received from healthcare providers to manage their arm morbidity. Results: Participants reported ongoing symptoms of pain (24%), lymphedema (21%), and range of motion limitation (34%) 30 to 36 months post-surgery. Pain was associated with experiencing swelling, taking pain medications, and discussing treatments for pain. Lymphedema was associated with swelling and receiving treatment for pain. ROM limitations were associated with swelling, receiving treatment for pain and taking pain medication. Two overarching qualitative themes emerged: 1) physical symptoms self-management, and 2) psychosocial self-management of uncertainty. Themes for treatments options included: rehabilitation and taking medications. Conclusion: Findings highlight that women living with symptoms of arm morbidity require ongoing monitoring and support for self-management, and there is a need for multidisciplinary approaches. Self-management practices reported are in line with the current lymphedema guidelines, however, the complexities associated with self-management practices can be burdensome to women. Chronic pain and ROM limitation necessitates further investigation to understand their cause and develop management strategies. Oncology nurses are well positioned to implement survivorship care plans that address survivorship needs with multidisciplinary teams and primary healthcare practitioners when women with breast cancer transition from acute cancer care to home. Future research is needed to provide an in depth understanding of self-management of arm morbidity in breast cancer survivors.

description: We introduce a coloured generalization $\mathrm{NSym}_A$ of the Hopf algebra of non-commutative symmetric functions described as a subalgebra of the of rooted ordered coloured trees Hopf algebra. Its natural basis can be identified with the set of sentences over alphabet $A$ (the set of colours). We present also its graded dual algebra $\mathrm{QSym}_A$ of coloured quasi-symmetric functions together with its realization in terms of power series in partially commutative variables. We provide formulas expressing multiplication, comultiplication and the antipode for these Hopf algebras in various bases -- the corresponding generalizations of the complete homogeneous, elementary, ribbon Schur and power sum bases of $\mathrm{NSym}$, and the monomial and fundamental bases of $\mathrm{QSym}$. We study also certain distinguished series of trees in the setting of restricted duals to Hopf algebras.
