description: In physics, biology and engineering, network systems abound. How does the connectivity of a network system combine with the behavior of its individual components to determine its collective function? We approach this question for networks with linear time-invariant dynamics by relating internal network feedbacks to the statistical prevalence of connectivity motifs, a set of surprisingly simple and local statistics of connectivity. This results in a reduced order model of the network input-output dynamics in terms of motifs structures. As an example, the new formulation dramatically simplifies the classic Erdos-Renyi graph, reducing the overall network behavior to one proportional feedback wrapped around the dynamics of a single node. For general networks, higher-order motifs systematically provide further layers and types of feedback to regulate the network response. Thus, the local connectivity shapes temporal and spectral processing by the network as a whole, and we show how this enables robust, yet tunable, functionality such as extending the time constant with which networks remember past signals. The theory also extends to networks composed from heterogeneous nodes with distinct dynamics and connectivity, and patterned input to (and readout from) subsets of nodes. These statistical descriptions provide a powerful theoretical framework to understand the functionality of real-world network systems, as we illustrate with examples including the mouse brain connectome.

description: The PHENIX experiment presents results from the RHIC 2006 run with polarized $p + p$ collisions at $\sqrt{s}$ = 62.4 GeV, for inclusive $\pi^0$ production at mid-rapidity. Unpolarized cross section results are measured for transverse momenta $p_T$ = 0.5 to 7 GeV/$c$. Next-to-leading order perturbative quantum chromodynamics calculations are compared with the data, and while the calculations are consistent with the measurements, next-to-leading logarithmic corrections improve the agreement. Double helicity asymmetries ALL are presented for $p_T$ = 1 to 4 GeV/$c$ and probe the higher range of Bjorken $x$ of the gluon ($x_g$) with better statistical precision than our previous measurements at $\sqrt{s}$ = 200 GeV. These measurements are sensitive to the gluon production in the proton for 0.06 < $x_g$ < 0.4.

description: RNA silencing is a cellular mechanism of post-transcriptional gene regulation which is highly conserved among the plant and animal kingdoms of life, and plays a critical part of developmental biology, maintenance of homeostasis, and host-pathogen interactions. The pathway is engaged by small double-stranded (ds)RNA molecules (small RNAs), which effect sequence specific gene silencing by targeting complementary RNA sequences. There are several classes of small RNAs which engage the pathway. MicroRNAs (miRNAs) are expressed in the genome as endogenous regulators of gene expression. Short-interfering RNAs (siRNAs) are usually from exogenous sources such as viral-derived short-interfering RNAs, or synthetic siRNAs which are applied to cells or organisms to inhibit expression of specific genes. The p19 protein is a viral suppressor of RNA silencing (VSRS) endogenous to tombusviruses, which binds small RNA duplexes of any sequence with extremely high affinity. Because of its unique binding properties, recombinant p19 proteins are an excellent platform for tool development surrounding the RNA silencing pathway and are used extensively in novel applications for modulating the activity of small RNAs in living systems and for detecting small RNAs in biological samples. Herein we present work that has increased the breadth of p19’s utility as a biotechnology tool in three distinct realms. First, we present a chemical biology approach which combines p19 and small molecules for potent inhibition of the RNA silencing pathway in human cells. Secondly, we present the development of a novel fusion protein between p19 and a cell penetrating peptide (CPP), which functions as an siRNA delivery agent to allow gene knockdown in human cells. Thirdly, we have improved the utility of p19 for detecting and sequestering human miRNAs through rationally designing the binding surface; we describe mutations which dramatically enhance p19's affinity for human miRNA-122. The work presented here adds to the growing repertoire of engineered RNA binding proteins (RBPs) as tools for studying small RNA molecules and modulating their activity for applications in human therapeutics.

description: As technology advances, so does our understanding of the world. Technology can act as that great disruptor which facilitates, (or hinders) access to cultural knowledge. Towards a National Collection (TaNC) is a 22m euro UK investment that aims to identify the pathways into such sustainable socio-technical infrastructures where all levels of knowledge and representation can be produced and used by diverse groups with different cultural needs of information, and therefore tools to make use of it. The Museo Integrado calls for museums to “take part in bringing awareness into the societies to which it serves”. However, this can become challenging due to the alienation generated by Western and Anglo-centric epistemologies, cosmovision and technologic impositions. How are museums meant to represent knowledge when the systems used to describe such knowledge do not engage with the perspective of the communities they are meant to serve? How do we overcome the large digital divide within cultural institutions, their staff, and especially among communities, not only in the context of the Global South, but also evident within the UK. The Digital Humanities have provided a paradigm shift in how knowledge production can sustain (and disrupt) novel research methods in the historic and cultural sector. TaNC research aims to identify such novel methods and integrate them within a sustainable model accessible for the wide range of users and non-direct users of cultural heritage.

A Probabilistic Modeling Approach to Hearing Loss Compensation
Creators: name: van de Laar, Thijs

Publisher: name: arXiv
Year: 2016
Subjects: subject: Machine Learning (stat.ML)
subject: FOS: Computer and information sciences

description: Hearing Aid (HA) algorithms need to be tuned ("fitted") to match the impairment of each specific patient. The lack of a fundamental HA fitting theory is a strong contributing factor to an unsatisfying sound experience for about 20% of hearing aid patients. This paper proposes a probabilistic modeling approach to the design of HA algorithms. The proposed method relies on a generative probabilistic model for the hearing loss problem and provides for automated inference of the corresponding (1) signal processing algorithm, (2) the fitting solution as well as a principled (3) performance evaluation metric. All three tasks are realized as message passing algorithms in a factor graph representation of the generative model, which in principle allows for fast implementation on hearing aid or mobile device hardware. The methods are theoretically worked out and simulated with a custom-built factor graph toolbox for a specific hearing loss model.
A Malleable Strategic Culture? Transatlantic Think Tanks as Autopoetic Systems
Creators: name: Wesselhoeft, William
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: This essay pioneers a systems theory/liberalist approach to strategic culture. Employing a 3rd generation definition of strategic culture which treats security decisions as culturally unique and scientifically traceable, it works with the theory of Niklas Luhmann and Andrew Moravcsik. Societal interest groups operate within a society/environment milieu in their creation of strategic culture. The milieu is self-referential, ‘autopoeitic.’ Think tanks, ‘Stiftung Wissenschaft und Politik’ (SWP) and ‘Deutsche Gesellschaft für Auswärtige Politik’ (DGAP), have their Transatlantic leanings evaluated as autopoeitic milieus, for societal actor interest and structural coupling. SWP and DGAP have very different levels of autonomy in their research agenda/productive output, and likely different influence in German foreign policy towards the Transatlantic relationship. Evident is a ‘thought bubble’ (autopoeisis) and high level of structural coupling with non-government donors in DGAP, compared to SWP, with high research/production output autonomy – no thought bubble – and a low level of potential structural coupling with private corporations. SWP can be considered a quangos (quasi non-governmental organization), while DGAP cannot be. Think tanks evaluated exhibit societal actor behavior, operationally closed or open to evolutionary developments. This indicates that think tanks, and other systems involved in foreign policy creation, are malleable. Strategic culture is malleable.

Online Covering: Efficient and Learning-Augmented Algorithms
Creators: name: Lin, Young-san
Publisher: name: Purdue University Graduate School
Year: 2022
Subjects: Data structures and algorithms

description: We start by slightly modifying the generic framework for solving online covering and packing linear programs (LP) proposed in the seminal work of Buchbinder and Naor (Mathematics of Operations Research, 34, 2009) to obtain efficient implementations in settings in which one has access to a separation oracle.
 We then apply the generic framework to several online network connectivity problems with LP formulations, namely pairwise spanners and directed Steiner forests. Our results are comparable to the previous state-of-the-art results for these problems in the offline setting.
 Further, we extend the generic frameworks to online optimization problems enhanced with machine-learning predictions. In particular, we present learning-augmented algorithms for online covering LPs and semidefinite programs (SDP), which outperform any optimal online algorithms when the prediction is accurate while maintaining reasonable guarantees when the prediction is misleading. Specifically, we obtain general online learning-augmented algorithms for covering LPs with fractional advice and general constraints and initiate the study of learning-augmented algorithms for covering SDPs.
Relationship between body mass index percentile and skeletal maturation and dental development in orthodontic patients
Creators: name: Mack, Kervin B.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Objective: To investigate the relationship between body mass index (BMI) percentile and skeletal and dental maturity. Methods: Orthodontic patients between 8 and 17 years of age were assessed using a retrospective chart review. Skeletal maturation was assessed using the Cervical Vertebral Method (CVM), dental age using the Demirjian method, and weight status using BMI percentile. Linear regression and logistic regression models were used to assess the effect of BMI percentile on dental age and CVM stage respectively. Results: 540 subjects were included. CVM stage and dental age were more advanced in subjects with increased BMI percentile. For dental age the coefficient for BMI percentile was 0.005 years per 1 unit increase (p<0.001) and the odds ratio for BMI percentile's effect on CVM was 1.02 (p<0.001). Conclusion: Orthodontists should consider weight status when evaluating the timing of growth modification treatment in growing patients.

Vascular endothelial cadherin phosphorylation modulates endothelial cell permeability and leukocyte transendothelial migration
Creators: name: Hart, Stephanie Hall.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Leukocyte transendothelial migration (TEM) is a key step in many functions of the immune system such as immune surveillance, inflammation and wound repair. The controlled disassembly of endothelial adherens junctions (AJs) is a major component of TEM regulation. Studies have shown the tyrosine phosphorylation of VE-cadherin, a protein important in AJs, disrupts junctions and increases vascular permeability. We found that blocking the phosphorylation of VE-cadherin on residues Y658 and Y731 using non-phosphorylatable VE-cadherin mutants lead to increased barrier function and decreased endothelial cell monolayer permeability. This demonstrates that phosphorylation of VE-cadherin residues Y658 and Y731 is necessary for the disassembly of endothelial junctions. We demonstrated that blocking phosphorylation of these residues also inhibited neutrophil transmigration across endothelial cells. Together, these data demonstrate that phosphorylation of VE-cadherin residues, Y658 and Y731, are required for the regulation of endothelial cell junction permeability and also for effective neutrophil transendothelial migration through endothelial cell monolayers.

description: We propose an explicit, easily-computable algebraic criterion for approximate null-controllability of a class of general piecewise linear switch systems with multiplicative noise. This gives an answer to the general problem left open in [13]. The proof relies on recent results in [4] allowing to reduce the dual stochastic backward system to a family of ordinary differential equations. Second, we prove by examples that the notion of approximate controllability is strictly stronger than approximate null-controllability. A sufficient criterion for this stronger notion is also provided. The results are illustrated on a model derived from repressed bacterium operon (given in [19] and reduced in [5]).

Capite Ablato: The Decapitation Motif in Tacitus' Histories
Creators: name: Beeby, John B.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Throughout Histories 1-3, Tacitus employs a motif of decapitation that functions as a metaphor for the anarchy of the so-called Year of the Four Emperors. The historian emphasizes certain beheadings common to the parallel tradition, and includes others that are unique to the Histories. Tacitus extends this motif to embrace metaphorical beheadings, the foremost of which is the destruction of the Capitolium, which marks the terrible climax of the first three books. Tacitus effectively abandons the motif in Histories 4 and focuses instead on Vespasian's good leadership and Rome's restoration. I conclude that Tacitus' use of this motif contributes to his negative analysis of Roman leadership in 69 CE.

Mapping the Phase Diagram of Quantum Chromodynamics via Fluctuations
Creators: name: Pradeep, Maneesha Sushama
Publisher: name: University of Illinois at Chicago
Year: 2023

description: An intriguing question about the phase diagram of QCD is the existence and the location of the critical point on the boundary between the two phases – the hadron gas and the quark-gluon plasma. Heavy-ion collisions provide a unique opportunity to look for signatures of this critical point via the event-by-event fluctuations of particle multiplicities. In order to make conclusive inferences from the experimental data, we need a theoretical framework to connect QCD thermodynamics to the particle spectra and correlations observed by the detectors. In this thesis, I use quantum-field-theoretic techniques to develop necessary ingredients to describe the thermodynamics, dynamics, and freeze-out of fluctuations in such a framework. In the first part of the thesis, we use universality of critical phenomenon and the lightness of physical quark masses to deduce certain non-trivial scaling features of the QCD equation of state (EoS). In the second part of the thesis, we demonstrate how slowing down near the critical point affects the growth of hydrodynamic fluctuations relative to the equilibrium expectations obtained using the EoS. In the final part, we propose a generalization to the half-a-century old Cooper-Frye freeze-out procedure to convert the fluctuations of hydrodynamic densities into particle correlations based on the universal maximum entropy principle. Applying the procedure, we derive relations to obtain important phenomenological constants that determine the magnitude of observed particle multiplicity fluctuations directly in terms of the QCD EoS.

Servants Not Soldiers: Lordship and Social Morality in the Via Regia
Creators: name: Gose, Allison
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Smaragdus of St. Mihiel’s Via regia captures a significant moment in Carolingian intellectual thought, emerging during the transition from Charlemagne to Louis the Pious. This thesis argues that ninth-century intellectuals, such as Smaragdus, possessed the historical awareness to recognize this pivotal change and craft innovative solutions to the questions it raised. Experimenting with models of rulership, thinkers constructed an ideal image to which king and noble could aspire, binding royal and aristocratic males to an evolving imperial project. A close examination of the writings of this abbot illuminates how those intimately involved in the court understood this succession and the imaginative opportunities it afforded for a new social order. This thesis thus analyzes the Via regia as a social and political guide for both royal and aristocratic administrators and how it aimed to inculcate universal principles of lordship necessary for the creation of a model Christian empire.

description: Research within the field of human motion assistive device development, with the purpose of reducing the metabolic cost of daily activities, is seeing the benefits of the exclusive use of passive actuators to store and release energy during the gait cycle. Designs of novel exoskeletons at the University of Ottawa implement the Pneumatic Artificial Muscle (PAM) as the primary method of nonlinear, passive actuation. The PAM is proven as a superior actuator for these devices when compared to the linear mechanical springs used by other researchers. There are, however, challenges regarding PAM pressure loss and the limitation of PAM elongation that have been identified. This thesis aims to develop a hyperelastic tubular soft composite that replicates the distinctive mechanical behaviour of the PAM without the need for internal pressurization. The final soft composite solution was achieved by impregnating a prefabricated polyethylene terephthalate braided sleeve, held at a high initial fibre angle, with a silicone prepolymer. A comprehensive experimental evaluation was performed on numerous prototypes for a variety of customizable design parameters including: initial fibre angle, silicone stiffness, and braided sleeve style. Moreover, two separate analytical models were formulated based on incompressible finite elasticity theory using either a structural model of Holzapfel’s type, or a phenomenological model of Fung’s type. Both models were in good agreement with the experimental data that were collected through a modified extension-inflation test. This research has successfully developed, tested, and validated an innovative soft composite that can achieve specific mechanical properties, such as contraction distance and nonlinear stiffness, for optimal use in human motion assistive devices.

description: Ma thèse étudie la quête initiatique dans des œuvres littéraires franco-canadiennes pour adolescents en se fondant sur les étapes présentées par Simone Vierne, soit la préparation, la mort initiatique et la renaissance. Je me suis intéressée à l’évolution de la quête initiatique dans la littérature jeunesse franco-canadienne entre les années 1970, époque où Vierne publie ses premiers travaux, et 2015 afin de voir si la littérature ne permet pas de suppléer aux rites de passage de moins en moins présents dans nos sociétés actuelles où la transition entre l’enfance et l’adolescence semble de moins en moins perceptible. La thèse présente une analyse de la valeur symbolique des éléments participants à la quête initiatique dans La vengeance de l’orignal de Doric Germain, La quête d’Alexandre d’Hélène Brodeur, Les grands sapins ne meurent pas de Dominique Demers, La première pluie de Camilien Roy, Cœur de lionne de Guy Armel Bayegnak et Le silence de la Restigouche de Jocelyne Mallet-Parent. Le corpus est divisé selon trois périodes, soit de 1970 à 1985, de 1986 à 2000 et de 2001 à 2015. L’analyse permet de vérifier si certains éléments sont récurrents d’une époque à l’autre ou de cerner les modifications qui touchent au déroulement de la quête initiatique à divers moments. C’est à partir de cette étude qu’il sera possible d’établir s’il y a une évolution dans le traitement de la quête initiatique de même que de formuler des hypothèses quant à la modélisation du roman initiatique franco-canadien pour adolescents. Le tout permettra de déterminer si le schéma proposé par Vierne est toujours pertinent dans le contexte actuel.

The Seiberg-Witten equations on end-periodic manifolds and an obstruction to positive scalar curvature metrics
Creators: name: Lin, Jianfeng
Publisher: name: arXiv
Year: 2016
Subjects: subject: Geometric Topology (math.GT)
subject: FOS: Mathematics

description: By studying the Seiberg-Witten equations on end-periodic manifolds, we give an obstruction on the existence of positive scalar curvature metric on compact $4$-manifolds with the same homology as $S^{1}\times S^{3}$. This obstruction is given in terms of the relation between the Frøyshov invariant of the generator of $H_{3}(X;Z)$ with the $4$-dimensional Casson invariant $λ_{SW}(X)$ defined by Mrowka-Ruberman-Saveliev. Along the way, we develop a framework that can be useful in further study of the Seiberg-Witten theory on general end-periodic manifolds.

description: Der Schmerz, etwas endgültig nicht zu bekommen, das wir unendlich begehren, wird am Beispiel der unglücklichen Liebe in drei Phasen veranschaulicht. In einer ersten Phase sind wir gefangen in der Qual der vergeblichen Hoffnung sowie der Hoffnungslosigkeit. In einer zweiten Phase stellt sich eine Art Verzweiflung ein, der Verlust jeder Hoffnung und zugleich des Vertrauens in uns selbst, wenn uns unser verzweifeltes Verhalten besser bewusst wird. Schließlich kann es mit einigem zeitlichen Abstand in einer dritten Phase zu einem Einbruch des Neuen kommen. Dieses Geschehen wird durch die Analogie der Entdeckung Amerikas durch Kolumbus veranschaulicht, welches lange für das gesuchte Indien gehalten wurde. Der Text versucht, die beschriebene Entwicklung parallel psychoanalytische (Lacans Objekt klein a) und philosophisch zu beschreiben. Ergebnis sind drei Bedeutungen einer Transformation des Begehrten.
description: Unrequited love can lead to a trap of hope and hopelessness, to despair and to a loss of confidence and trust in ourselves. These feelings can lead to a conversion and reconstruction of ourselves. Presumably, after a period of time a new perspective is possible. In the text, this view is delineated by the historic event of Columbus discovering America which was for a long time considered to be India. The mentioned development is described both, by psychoanalytical (Lacans object small a) and philosophical terms. As a result, three meanings of a transformation of what is desired are presented in detail.
Reliability of a Visual Observation Pitching Assessment in Adolescent Pitchers
Creators: name: Quatromoni, Emily
Publisher: name: University of North Carolina at Chapel Hill Graduate School

Subjects: Medicine

description: Pitching mechanical errors are potential risk factors for upper extremity injury in baseball pitchers. Creating a reliable assessment tool will allow coaches and sports medicine professionals to identify faulty pitching mechanics and correct these mechanics before injury occurs. The purpose of this study was to establish the intra- and inter-rater reliability of previously studied biomechanical errors that have been linked to injurious stresses. Each participant pitched a minimum of ten pitches that included a minimum of three strikes, while frontal and sagittal video was collected. Separate Cohen's kappa coefficients were used to establish reliability. Acceptable intra-rater reliability was established for all six biomechanical errors. Acceptable inter-rater reliability was established for three out of the six errors. This study lays the foundation for the development of a clinically applicable assessment tool which has the potential of identifying faulty pitching mechanics to decrease the injury associated with pitching.

description: Die Fülle des Lebens ist ein berechtigter Wunsch. Das Problem ist, dass wir diese Fülle oft im Sinne einer Logik der Steigerung suchen in einem 'immer mehr'. So arbeiten wir immer mehr und unsere freiwilligen Verpflichtungen in der Familie und in der Freizeit steigen immer weiter. Das Ergebnis ist das 'Hamsterrad', die Falle eines uns überanstrengenden Lebens. Der Text versucht aufzuzeigen, wir wir die Fülle des Lebens in eine andere Richtung suchen können: nicht im 'immer mehr', sondern in der Tiefe des Lebens. Davon halten wir uns oft selbst ab: durch die Haltung eines Aktivismus, durch den Wunsch nach schmerzfreien Erlebnissen und durch den Druck der Selbstoptimierung.
description: We long for the abundance of our life. Trouble is that we look for it with a logic of increase. We work harder and harder and we play harder and harder. The result is the well known rat race, the trap of an overexerting life. In the text, it is shown how to look for the abundance of life in an alternative direction. That means to open up the depth of life instead of the logic of 'more and more'. But our daily life and usual attitude deters us from this alternative direction. These attitudes are activism, the wish for experiences without suffering and the pressure of self-optimization.

description: La résistance au feu d'un élément de charpente peut être définie par sa capacité de résistance à l'exposition au feu sans perdre sa fonction de support de charge ni sa capacité de servir d'obstacle à la propagation du feu. Cet élément de charpente doit donner le temps aux gens d'évacuer le bâtiment avant qu'il ne s'effondre, et il est essentiel pour confiner le feu au compartiment où il a pris naissance. La résistance au feu de divers éléments de charpente, tels que les poutres, les poteaux ou les murs, peut être déterminée par des essais ou, dans beaucoup de cas, par calcul, ce qui est de loin meilleur marché et plus rapide. Bien que la détermination expérimentale de la résistance au feu soit encore la méthode la plus commune, les progrès dans le domaine de la prédiction théorique ont été rapides ces dernières années. Nous avons l'intention de présenter un rapport du niveau actuel des connaissances et de décrire quelques aspects des études liées à la résistance au feu qui sont en cours à la Division des recherches sur le bâtiment, du Conseil national de recherches du Canada.
