Abstract:
Unification Models of Active Galactic Nuclei postulate that all the observed differences between type 1 and type 2 objects are due to orientation effects with respect to the line of sight to the observer. The key ingredient of these models is the obscuring medium, historically envisaged as a toroidal structure on a parsec scale. However, many results obtained in the last few years are clearly showing the need for a more complex geometrical distribution of the absorbing media. In this paper, we review the various pieces of evidence for obscuring media on different scales, from the vicinity of the black hole to the host galaxy, in order to picture an updated unification scenario explaining the complex observed phenomenology. We conclude by mentioning some of the open issues.

Abstract:
This paper addresses the cryptanalysis of a secure communication scheme proposed by Wu (2006), where the information signal is modulated into a system parameter of a unified chaotic system. It is demonstrated that a parameter observer can be designed to identify the parameter determined by the transmitted information and then the transmitted information can be obtained. Compared with the existing analysis using adaptive observer, the cryptanalysis based on parameter observer is much simpler and needs less structure information of the transmitter system. With numerical simulations, it is shown that the parameter observer has stronger practicality and robustness. Furthermore, it is still possible to obtain the transmitted information, even if the derivative of the transmitted signal is unknown.

Abstract:
This study evaluated the reliability and comprehensiveness of the Unified classification system (UCPF), Wright & Cofield, Worland and Kirchhoff classifications and related treatment recommendations for periprosthetic shoulder fractures (PPSFx). Two shoulder arthroplasty specialists (experts) and two orthopaedic residents (non-experts) assessed 20 humeral-sided and five scapula-sided cases of PPSFx. We used the unweighted Cohen’s Kappa (κ) for measuring the intra-observer reliability and Krippendorff’s alpha (α) for measuring the inter-observer reliability. The inter-rater reliabilities for the Wright & Cofield and Worland classifications were substantial for all groups. The expert and non-expert groups for UCPF also showed substantial inter-rater agreement. The all-rater group for the UCPF and the expert and non-expert group for the Kirchhoff classification revealed moderate inter-rater reliability. For the Kirchhoff classification, only fair inter-rater reliability was found for the non-expert group. Almost perfect intra-rater reliability was measured for all groups of the Wright & Cofield classification and the all-rater and expert groups of the UCPF. All groups of the Kirchhoff and Worland classifications and the group of non-experts for the UCPF had substantial intra-rater reliabilities. Regarding treatment recommendations, substantial inter-rater and moderate intra-rater reliabilities were found. Simple classification systems for PPSFx (Wright & Cofield, Worland) show the highest inter- and intra-observer reliability but lack comprehensiveness as they fail to describe scapula-sided fractures. The complex Kirchhoff classification shows limited reliability. The UCPF seems to offer an acceptable combination of comprehensiveness and reliability.

Abstract:
Les lois de contrôle des machines à courant alternatif, asynchrones et synchrones, sont aujourd'hui assez mûres. Le contrôle vectoriel est un cadre général pour la modélisation, l'analyse et le contrôle des machines à courant alternatif. Une approche de synthèse basée sur le modèle est souvent utilisée, et les paramètres de la loi de commande sont définis en fonction des paramètres de la machine. Un variateur de vitesse standard est utilisé dans la plupart des applications industrielles pour contrôler la vitesse du moteur alimenté par le réseau électrique. Dans ce cas, le variateur est appelé « variateur polyvalent ». Selon le type de machine à courant alternatif, un contrôleur spécifique est nécessaire. Pour ce faire, les fabricants de variateurs devront inclure différentes lois de commande dans leur variateur. Par conséquent, l'ajout de ces lois nécessitera beaucoup de mémoire et de capacité de calcul. En outre, le changement de type de machine modifierait la loi de commande. Ce problème peut entraîner de nombreuses difficultés, telles que des coûts d'installation plus élevés, des délais de mise en service et des réglages supplémentaires. C'est pourquoi la recherche d'un « universal drive » se poursuit depuis plus d'une décennie. Cette thèse présente une étude approfondie sur le sujet de la commande unifiée pour les machines à courant alternatif. Notre objectif est d'innover une loi de commande unifiée pour les machines électriques, en particulier les machines asynchrones et synchrones, à utiliser dans les futurs produits de variateurs de vitesse à usage général. Dans le cadre de cette thèse, nous abordons l'unification de la modélisation, la conception d'observateurs et les aspects de contrôle dans le contexte des machines à courant alternatif. Pendant des décennies, les modèles CA ont été étudiés séparément dans la littérature. Cependant, grâce aux similitudes entre les machines électriques, un cadre de modélisation unifié est proposé. Le modèle unifié repose sur des paramètres équivalents du stator facilement identifiables, quel que soit le type de machine. Sur la base du modèle unifié, une contribution clé a été apportée dans cette étude, à savoir la conception de trois nouveaux observateurs de flux unifiés pour suivre les positions du flux du rotor ou du stator, quel que soit le type de moteur. Grâce à l'observateur de flux unifié, une loi de commande vectorielle unifiée pour les machines à courant alternatif devient possible. Les données expérimentales vérifient la loi de commande proposée pour les machines à induction et les machines synchrones à aimant permanent. Théoriquement, la solution proposée met en évidence le potentiel d'une «universel drive » qui n'a besoin d'aucune information sur le type de moteur. Cependant, la loi de commande unifiée donne de mauvais résultats à faible vitesse, alors qu'une méthode de démarrage unifiée est nécessaire
The control laws of AC machines, asynchronous and synchronous, are pretty mature today. Vector control is a general framework for AC machines' modeling, analysis, and control. A model-based synthesis approach is often used, and the control law parameters are defined according to the machine parameters. A standard variable speed drive is used in most industrial applications to control the speed of the motor powered by the electrical network. In this case, the drive is called a “general-purpose drive”. Depending on the type of AC machine, a specific controller is needed. This will require the drive's manufacturers to include different control laws in their drive. Consequently, adding these laws will require a lot of memory and computing capacity. Furthermore, changing the machine type would alter the control law. This problem could lead to many issues such as higher installation costs, commissioning time, and additional tuning. For this reason, the search for a "universal drive" scheme has been going on for more than one decade.This thesis presents an in-depth study on the subject of unified control for AC machines. Our goal is to innovate a unified control law for electric machines, particularly asynchronous and synchronous machines, for use in future general-purpose variable speed drive products. As a part of this thesis, we address the unification of modeling, observer design, and control aspects in the context of AC machines. For decades, the AC models have been studied separately in the literature. However, thanks to the similarities between electric machines, a unified modeling framework is proposed. The unified model relies on easily identifiable stator equivalent parameters regardless of the specific type of machine. Based on the unified model, a key contribution was made in this study, which is the design of three novel unified flux observers to track rotor or stator flux positions, regardless of the motor type. Thanks to the unified flux observer, a unified vector control law for AC machines becomes possible. Experimental data verify the proposed control law for induction machines and permanent magnet synchronous machines. Theoretically, the proposed solution highlights the potential for a “universal AC motor drive" that doesn't need any information on the motor type. However, the unified control law performs poorly at low speeds, where a unified startup method is needed

Abstract:
Un système de puissance électrique est un réseau complexe de composants électriques utilisés pour fournir, transmettre et utiliser l'énergie électrique. Son objectif final est d'offrir un service fiable, sécurisé et ininterrompu à l'utilisateur final, cela signifie, tension constante et fréquence constante en tout temps. Aujourd'hui, la tendance de la production d'électricité est vers un réseau interconnecté de lignes de transmission reliant la génération et les charges dans des grands systèmes intégrés. En fait, un réseau de système de puissance est considéré comme la machine la plus complexe et plus jamais construite par l'homme car elle peut s'étendre sur tout un continent. Pour cette raison, l'amélioration de la stabilité transitoire des réseaux électriques est d'une grande importance dans la société humaine, car si la stabilité est perdue, le collapse de la puissance peut se produire dans une grande zone peuplée et de graves dommages seront portées à l'économie régionale et les conforts des consommateurs. Par conséquent, compte tenu de tous les problèmes présentés avant, ce travail de recherche aborde la stabilisation transitoire des systèmes de puissance multi-machines soumises à des perturbations du réseau à partir de deux approches: la centralisation, qui considère aucune limitation dans l'échange d'informations d'un réseau donné, et d'autre part, la décentralisation, qui suppose l'échange d'informations n'est pas disponible. À cette fin, d'abord, nous introduisons une nouvelle théorie de commande pour stabiliser globalement systèmes triangulaires non linéarisables globalement en utilisant une commande de rétroaction d'état dynamique non linéaire, qui diffère de backstepping puisque la forme stricte de rétroaction n'est plus nécessaire. Ensuite, sur la base de ces nouvelles idées, le problème de stabilisation transitoire des systèmes de puissance est résolu d'un point de vue centralisé, en assurant la stabilité asymptotique globale du point de fonctionnement, dans certaines conditions sur les paramètres physiques du système. Postérieurement, en utilisant uniquement les mesures locales disponibles avec la technologie existante, le contrôleur central précédent est transformé en un décentralisé, à condition que la dérivée de la puissance active à chaque générateur peut être appropriement estimée. La performance des deux contrôleurs est testée par des simulations numériques envisagent plusieurs scénarios de défaut en utilisant le système de 10 machines de Nouvelle-Angleterre. Contrairement aux solutions non linéaires ci-dessus, nous proposons une méthodologie basée sur observateur pour la stabilisation décentralisée des systèmes linéaires invariants dans le temps. L'originalité de ce travail repose sur le fait que chaque contrôleur local est fourni avec des mesures locales disponibles, il met en œuvre un observateur pour reconstruire l'état des autres sous-systèmes et utilise de manière équivalente ces estimations dans la loi de commande. Les observateurs sont conçus en suivant les principes de l'immersion et l'invariance. De plus, la classe des systèmes est identifiée par une solution d'une inégalité matricielle linéaire, à partir de laquelle on obtient les gains d'observateurs
An electric power system (EPS) is a complex network of electrical components used to supply, transmit and use electric power. Its final goal is to provide reliable, secure and uninterrupted service to the end-user, this means, constant voltage and frequency at all time. Nowadays, the trend in electric power production is toward an interconnected network of transmission lines linking generators and loads into large integrated systems. Actually, a power system network is considered the most complex and bigger machine ever built by man since it can span an entire continent. For this reason, improving power system transient stability is of great significance in human society, since if the stability is lost, power collapse may occur in a large populated area and serious damages will be brought to a regional economy and the consumer's comforts. Therefore, considering all issues presented before, this research work tackles the transient stabilization of a multi-machine EPS subject to network disturbances from two approaches: centralization which considers no limitation in information exchange at any point of a given network, and on the other hand, decentralization which assumes the information exchange is not available. To this end, first we introduce a novel control theory to globally stabilize non-globally linearizable triangular systems employing a nonlinear dynamic state-feedback controller, which differs from standard backstepping since the strict-feedback form is no longer required. Then, based on these new ideas, the transient stabilization problem of EPS is solved from a centralized point of view ensuring, under some conditions on the physical parameters of the system, global asymptotic stability of the operating point. Subsequently, using only local measurements available with existing technology, the previous central controller is transformed into a truly decentralized one, provided that the derivative of the active power at each generator can be suitable estimated. Performance of both controllers is tested via numerical simulations considering several fault scenarios using the 10-machine New England benchmark. In contrast to the nonlinear solutions above, we offer an observer--based methodology for decentralized stabilization of large--scale linear time--invariant systems. The originality of this work relies on the fact that each local controller is provided with available local measurements, it implements a deterministic observer to reconstruct the state of the other subsystems and uses in a certainty--equivalent way these estimates in the control law. The observers are designed following the principles of immersion and invariance. Furthermore, the class of systems to which the design is applicable is identified via a linear matrix inequality solution, from which the observer gains are obtained

The work developed in this manuscript addresses the synchronization of chaotic systems. It is organized around two main axes: the observer synthesis and the mode detection. In a first step, we recall the main architectures of chaotic encryption systems and show how chaotic systems with polynomial nonlinearities or switched affine dynamics can be rewritten in a polytopic LPV form. A review of the main LMI based results for polytopic LPV observers synthesis is made. An extension to polytopic unknown input observers, both in the deterministic case and noisy or uncertain case, is proposed. These observers ensure chaos synchronization and information recovering in the framework of the following encryption systems: "parametric modulation", "chaotic switching", "two channels transmission" and "inclusion encryption". For affine switched systems used as a generator of chaos, the case where the discrete state is not available is considered. A unified presentation of mode detection methods based on parity spaces proposed in the literature for linear and affine switched discrete time systems is proposed. The problem of discernibility is the subject of a complete study. An approach to estimate time varying delays for affine switched discrete time systems, formulated in terms of mode detection, is proposed as a solution for delay injection encryption

Abstract:
A osteomielite possui elevada prevalência e morbidade. O tratamento depende de apropriada terapia antimicrobiana por tempo prolongado e frequentemente requer cirurgia para remoção de tecidos necróticos. A aderência dos pacientes com osteomielite à prescrição do antibiótico, embora fundamental para o sucesso terapêutico, tem sido pouco estudada. O objetivo deste estudo foi mensurar a aderência à terapia antimicrobiana oral em pacientes adultos com osteomielite; identificar se alguns fatores relacionados na literatura estavam associados com a não aderência; estabelecer o valor preditivo dos fatores associados a não aderência ao tratamento em pacientes com osteomielite. Foi realizado um estudo transversal, fundamentado na avaliação por meio de métodos indiretos da aderência para 83 pacientes. Foram considerados pelo menos 30 dias de uso do antimicrobiano à entrevista e os pacientes foram classificados como aderentes de acordo com o questionário de Morisky, que é constituído por 4 questões com respostas dicotômicas para avaliar a aderência. Os pacientes com < 2 pontos foram considerados de baixa aderência e os que obtiverem > 3 pontos, de alta aderência. O presente estudo identificou uma prevalência de alta aderência de 83,1% (n=63). O ajuste dos modelos de regressão logística múltipla não resultou em variáveis conjuntas influenciando a aderência ao tratamento, porém pacientes do gênero masculino sugeriram apresentar maior frequência de baixa aderência ao tratamento em relação aos pacientes do gênero feminino (p = 0,053). Com relação à idade, a análise dos dados mostrou que os pacientes com idade entre 31 e 59 anos possuíam probabilidade de baixa aderência 68% menor que pacientes com idade entre 18 e 30 anos. A aderência observada foi semelhante à encontrada na literatura. Os fatores sociodemográficos podem interferir na aderência de pacientes em uso de antibióticos orais para tratamento de osteomielite
Osteomyelitis is a highly prevalent disease and a major cause of morbidity. Clinical treatment is based on appropriate antimicrobial therapy. Adherence of patients with osteomyelitis to the prescribed treatment, although critical for successful treatment, has been little studied. The aim of the study was: to measure the adherence to oral antimicrobial therapy in adult patients with osteomyelitis; to identify whether some of the factors listed in health literature were associated with non-adherence; to establish the predictive values associated with non-adherence to antimicrobial therapy in patients with osteomyelitis. We conducted a cross-sectional study, based on evaluation through indirect methods of adherence for 83 patients. We included patients receiving at least 30 days of antimicrobial use. Patients were interviewed and classified as adherent according to the Morisky questionnaire, that consists of 4 questions with dichotomous responses to assess adherence. Patients with 3 points, with high adherence. This study identified a prevalence of high adherence of 83.1% (n = 63). The multivariate logistic regression analysis did not result in multiple variables influencing adherence to treatment. Gender was the only variable with an suggested association with low adherence, male gender was more associated with low adherence than female (p = 0,053). Regarding age, data analysis showed that patients aged between 31 and 59 years had low adherence probability 68% lower than patients aged between 18 and 30 years. The high adherence observed in this study was similar than previous reported in the literature. Social and demographic factors may interfere in the adherence with patients using oral antibiotics for the treatment of osteomyelitis

Abstract:
The chapter explains how the Principle of Least Action yields a unique answer to a physical problem irrespective of the frame of reference. The motivation arises from d’Alembert’s rousing words: “To someone who could grasp the Universe from a unified standpoint the entire creation would appear as a unique truth and necessity.” The requirement is that one “algorithm” can cope with all the specificity, variety, and complexity across the whole of physics. That one algorithm could ever be up to the task is made plausible by use of an allegory involving a King, the princess, and some suitors. Finally, the link with Least Action is made. Note that the terms extremal, objectivity, observer, and viewpoint are explained.

Full text
Abstract:
An examination of vowel harmony in Nata (Bantu, E45), reveals a fairly straightforward pattern of harmony in tongue root values for adjacent mid vowels. A problem arises, however, when we look at the behavior of harmony in prefixes. In some nouns, the class prefixes are retracted when the initial root vowel is retracted and advanced when the initial root vowel is advanced. Problematic, however, are other forms in which roots with initial retracted vowels condition the appearance of high vowels in the noun class prefixes. In earlier work, Gambarage argued that to account for the distinction between cases where mid vowels retract and cases where mid vowels raise to high, it is necessary to invoke two distinct co-phonologies. It is argued that the two patterns observed in Nata are readily accounted for within an “allomorphy account,” without the need to invoke multiple co-phonologies. The integration of general phonotactics governing vowel harmony with allomorphy appropriate for particular roots derives the two patterns in a unified fashion.

Abstract:
Emotion dysregulation—which is often defined as the inability to modulate strong affective states including impulsivity, anger, fear, sadness, and anxiety—is observed in nearly all psychiatric disorders. These include internalizing disorders such as panic disorder and major depression, externalizing disorders such as conduct disorder and antisocial personality disorder, and various other disorders including schizophrenia, autism, and borderline personality disorder. Among many affected individuals, precursors to emotion dysregulation appear early in development, and often predate the emergence of diagnosable psychopathology. Collaborative work by Drs. Crowell and Beauchaine, and work by many others, suggests that emotion dysregulation arises from both familial (coercion, invalidation, abuse, neglect) and extrafamilial (deviant peer group affiliations, social reinforcement) mechanisms. These studies point toward strategies for prevention and intervention. The Oxford Handbook of Emotion Dysregulation brings together experts whose work cuts across levels of analysis, including neurobiological, cognitive, and social, in studying emotion dysregulation. Contributing authors describe how early environmental risk exposures shape emotion dysregulation, how emotion dysregulation manifests in various forms of mental illness, and how emotion dysregulation is most effectively assessed and treated. This is the first text to assemble a highly accomplished group of authors to address conceptual issues in emotion dysregulation research; define the emotion dysregulation construct at levels of cognition, behavior, and social dynamics; describe cutting-edge assessment techniques at neural, psychophysiological, and behavioral levels of analysis; and present contemporary treatment strategies. Conceptualizing emotion dysregulation as a core vulnerability to psychopathology is consistent with modern transdiagnostic approaches to diagnosis and treatment, including the Research Domain Criteria and the Unified Protocol, respectively.

Abstract:
Abstract Science is largely a bipartisan endeavor. Most scientists have no difficulty identifying with one of two camps, which can be called, with about as much accuracy as names attached to political parties, theorists and experimentalists. An astute observer of scientists and their ways, Freeman Dyson, has offered a roughly equivalent, but more inspired, division of scientific allegiances and attitudes. In Dyson’s view, science has been made throughout its history in almost equal measure by “unifiers” and “diversifiers.” The unifiers, mostly theorists, search for the principles that reveal the unifying structure of science. Diversifiers, likely to be experimentalists, work to discover the unsorted facts of science. Efforts of the scientific unifiers and diversifiers are vitally complementary. From the great bodies of facts accumulated by the diversifiers come the unifier’s theories; the theories guide the diversifiers to new observations, sometimes with disastrous results for the unifiers.

Abstract:
Abstract Systems theorists generally assume that a distinction must be made between the legal system and the political system. These systems are seen as different sub-systems of society. This is especially true if we embrace the concept of autopoiesis and insist upon the autonomy and historical individuality of all social systems. However, most other social theorists reject this viewpoint because of the close and obvious relationship between politics and law. A theory of the autopoietic, operatively closed legal system envisages that this system is able to draw a distinction between itself and other functioning systems. Hence if any external observer of the system wants to observe and describe it appropriately, he will eventually confront this distinction, which is produced in the system itself. Even if this is plausible on the whole, it creates a problem regarding the relationship between politics and law. A long tradition, going back to early modem times, makes us inclined to see only a unified politico-legal system.

Abstract:
Abstract National identity is frequently asserted through the collective singing of meaningful songs. While national anthems are the most prominent, many other types of repertoire—folk songs, “fakesongs” (imitation folks songs), popular songs, patriotic songs, and choral compositions—can also serve to construct and broadcast national identity. The act of collective singing impacts both the participant and the observer. The participant embodies text and sound that signify national identity, although they might do so either willingly or under coercion. The observer perceives a unified expression of national identity, voiced by a collective, that might inspire reactions ranging from pride to terror. As chapters in this section demonstrate, collective singing is employed to assert national identity in a wide variety of formal and informal settings.

Abstract:
A solution framework using Hamiltonian paths and strand grids (HAMSTR) is presented for three-dimensional flows on overset and hybrid meshes. The methodology creates a volume mesh starting from an unstructured surface mesh that can be comprised of mixed triangular-quadrilateral elements. "Linelets" through the meshes are found in a robust manner and the solver uses line-implicit schemes and high-order reconstruction schemes along these linelets, similar to a structured solver. The mesh system is also extended to utilize overset meshes. This overset technique allows for multiple mesh systems, which consists of a near-body Hamiltonian/Strand grid and off-body Cartesian nested meshes. The generalized approach to obtaining the Hamiltonian paths allows for initially structured and unstructured meshes to be quilted together to form a unified grid. In such cases, Hamiltonian paths can cross themselves; however, no changes are necessary for the flow solver. Finally, the integration framework between the various components of the code suite is performed using Python to allow for ease of integration in the future to other codes. Aerodynamic flows past an airfoil, sphere, wing and non-lifting rotor are presented using the Hamiltonian/Strand approach and good agreement was observed against experimental results as well as solutions obtained from traditional structured solvers.

Abstract:
In times of crisis, decision-making becomes paramount, yet it is often influenced by two distinct behavioural patterns: analysis paralysis and risk aversion. Drawing a parallel between the studies presented in this brief, it is possible to discern the interplay of analysis paralysis and risk aversion within institutional responses to crises. The research from the African School of Economics (ASE) examines the phenomenon of analysis paralysis within the context of democratic institutions. It highlights the correlation between democratic rights and long-term economic prosperity while cautioning against the negative consequences of reversing these rights. The study delves into potential mechanisms contributing to the deterioration of democratic institutions during crises, including limited collective action and the acceptance of repressive policies. By analysing survey results from Benin, Burkina Faso, and South Africa, the research uncovers varying degrees of acceptance of perceived repressive policies and willingness to protest, shedding light on the vulnerability of democratic institutions when faced with analysis paralysis. These findings underscore the importance of addressing decision-making bottlenecks, encouraging timely action, and fostering an environment where collective action is possible. Contrasting this, the research from Colabora.Lat focuses on the impact of risk aversion in institutional responses to the pandemic. The findings emphasise the importance of collaboration, highlighting how governments and various actors working together can effectively address the multifaceted challenges posed by crises. Through the lens of risk aversion, the study explores how collaboration enabled governments to combine resources, knowledge, and experiences to produce unified messages and mitigate the worst health impacts. It showcases the successes observed in countries such as Argentina, Bolivia, Chile, Colombia, Guatemala, and Mexico, where collaborative governance fostered effective policy outcomes, including lower mortality rates. By combining the insights from these texts, we gain a comprehensive understanding of the challenges and opportunities faced by institutions during times of crisis. Acknowledging the potential pitfalls of analysis paralysis and the transformative potential of collaborative responses, policymakers and decision makers can navigate crises with more agility, ensuring the preservation of democratic institutions and mechanisms while effectively addressing the health and socioeconomic impacts of crises.
