En la actualidad el empleo de vehículos aéreos no tripulados (VANT) es muy recurrente en diversas aplicaciones industriales, comerciales, ambientales, académicas, investigación, entre otras. Uno de los temas centrales de estos vehículos es su correcta manipulación/control en ausencia del ser humano. Sin embargo, esto no se puede alcanzar sin la puesta en operación y el empleo de modelos matemáticos. En este manuscrito se presenta la puesta en operación del VANT conocido como Matrice 100 de DJI, además del empleo de las técnicas más recurrente encontradas en la literatura para la obtención de su modelo matemático correspondiente. Este VANT es una plataforma experimental con base de fibra de carbón y cuatro rotores, cuenta con un software (simulador de vuelo) de arquitectura abierta para la comunicación/manipulación; desarrollado en el entorno integral libre Android Studio. Para el modelo matemático se considera una configuración en CRUZ y se emplea la metodología propuesta por Euler-Lagrange para describir las dinámicas traslacionales y rotacionales caracterizando las energías cinéticas y potenciales involucradas, teniendo como resultado un modelo no lineal subactuado de orden doce. Para corroborar el buen funcionamiento y la manipulación de la plataforma experimental; así como su correspondencia con el modelo matemático, se presentan simulaciones desarrolladas en Simulink-Matlab y el simulador de vuelo del fabricante, además de pruebas experimentales. Para lo anterior, se emplea un control clásico PD sintonizado solo para alcanzar una altura z en el VANT (considerando solo dinámicas traslacionales).

Questo articolo nasce dall'esigenza di informare un più ampio pubblico sul pericolo rappresentato da queste sostanze, far conoscere le NPS (Novel Psychoactive substances) agli operatori del settore (personale di laboratorio, personale delle unità di emergenza/ urgenza, operatori sanitari, ricercatori, ecc.) al fine di agevolare l'analisi di campioni sconosciuti e divulgare i dati scientifici che cominciano ad emergere da studi clinici e preclinici sui loro effetti tossici e farmacologici. Dal 2009 sono comparsi nel gruppo delle N.P.S., i nuovi oppioidi sintetici, molecole estremamente potenti che comportano una seria minaccia per la salute pubblica. Si tratta di prodotti dalla notevole potenza (il fentanyl, per esempio, capostipite di questa famiglia, ha un'azione circa 100 volte maggiore rispetto a quella della morfina) che vengono utilizzati sia per sé sia come adulteranti di partite di sostanze classiche, soprattutto eroina, causando scie di decessi per overdose.

Human eyeballs move relative to the head, resulting in optimal changes in the viewpoint. We tested similar vestibular ocular reflex (VOR)-based movement on Zenmuse-X3 gimbal camera relative to pre-defined YAW movements of the DJI Matrice-100 unmanned aerial vehicle (UAV). Changes in viewpoint have various consequences for visual and graphical rendering. Therefore, this study investigated how to minimize these changes. OpenGL visualization was performed to simulate and measure viewpoint changes using the proposed VOR-based eyeball movement algorithm and compared with results of VOR based gimbal movement. The gimbal camera was setup to render images (scenes) on flat monitors. Positions of pre-fixed targets in the images were used to measure the viewpoint changes. The proposed approach could successfully control and significantly reduce the viewpoint changes and stabilize the image to improve visual tracking of targets on flat monitors. The proposed method can also be used to render real-time camera feed to a head-mounted display (HMD) in an ergonomically pleasing way.

In this article, we design a low-cost navigation system for a quadrotor working in unknown outdoor environments. To reduce the computing burden of the quadrotor, we build a separated system and transfer the computing resources from onboard side to ground station side. Both sides’ communication is guaranteed by 5G wireless networks. We utilize a stereo camera to acquire point clouds and build Octomap for the quadrotor’s navigation. Then, the trajectory is generated in two stages. In the first stage, a modified RRT*-CONNECT algorithm is adopted to generate a set of collision-free waypoints. In the second stage, a curve fitting algorithm is utilized to get a smooth piecewise Bezier trajectory. The advantage of the proposed method is to optimize the path into a safe, smooth, and dynamically feasible trajectory in real time. The modules of the state estimation, dense mapping, and motion planning are integrated into a DJI Matrice 100 quadrotor. Finally, simulation and experiments are both conducted to show the validity and practicality of our method.

This paper summarizes the concept of swarm robotics and its applicability to crop inspections. To increase the agricultural yield it is essential to monitor the crop health. Hence, precision agriculture is becoming a common practice for farmers providing a system that can inspect the state of the plants (Khosla and others, 2010). One of the rising technologies used for agricultural inspections is the use of unmaned air vehicles (UAVs) which are used to take aerial pictures of the farms so that the images could be processed to extract data about the state of the crops (Das et al., 2015). For this process both fixed wings and quadrotors UAVs are used with a preference over the quadrotor since it’s easier to operate and has a milder learning curve compared to fixed wings (Kolodny, 2017). UAVs require battery replacement especially when the environmental conditions result in longer inspection times (“Agriculture - Maximize Yields with Aerial Imaging,” n.d., “Matrice 100 - DJI Wiki,” n.d.). As a result, inspection systems for crops using commercial quadrotors are limited by the quadrotor´s maximum flight speed, maximum flight height, quadrotor´s battery time, crops area, wind conditions, etc. (“Mission Estimates,” n.d.).Keywords: Swarm Robotics, Precision Agriculture, Unmanned Air Vehicle, Quadrotor, inspection.

For years, urban air quality networks have been set up by private organizations and governments to monitor toxic gases like NO2. However, these networks can be very expensive to maintain, so their distribution is usually widely spaced, leaving gaps in the spatial resolution of the resulting air quality data. Recently, electrochemical sensors and their integration with unmanned aerial vehicles (UAVs) have attempted to fill these gaps through various experiments, none of which have considered the influence of a UAV when calibrating the sensors. Accordingly, this research attempts to improve the reliability of NO2 measurements detected from electrochemical sensors while on board an UAV by introducing rotor speed as part of the calibration model. This is done using a DJI Matrice 100 quadcopter and Alphasense sensors, which are calibrated using regression calculations in different environments. This produces a predictive r-squared up to 0.97. The sensors are then calibrated with rotor speed as an additional variable while on board the UAV and flown in a series of flights to evaluate the performance of the model, which produces a predictive r-squared up to 0.80. This methodological approach can be used to obtain more reliable NO2 measurements in future outdoor experiments that include electrochemical sensor integration with UAV’s.

L’amélioration de la prise en charge médicamenteuse est un objectif constant des équipes en charge de la qualité et de la gestion des risques liés aux soins. En psychiatrie, le circuit du médicament concerne à la fois les secteurs intra et extrahospitaliers, pour lequel l’analyse des risques est parfois moins maîtrisée. L’objectif de ce travail est d’établir une cartographie des risques, a priori, du circuit du médicament du secteur extrahospitalier de notre établissement (800 lits) afin d’aboutir à l’élaboration de recommandations pour la sécurisation de ce circuit. Un état des lieux du fonctionnement du circuit du médicament en secteur extrahospitalier a été réalisé en collaboration avec la cellule qualité de janvier à juin 2015 au sein de 11 centres médico-psychologiques et 10 centres et/ou hôpitaux de jour. Les données recueillies lors de cette étude observationnelle ont été analysées selon la méthode AMDEC (analyse des modes de défaillance, de leurs effets, et de leur criticité). Après pondération (construction d’une matrice), les divers circuits ont été modélisés en logigrammes intégrant différents points (conciliation médicamenteuse, conditions de prescriptions, de délivrance, et d’administration) et comportant sept issues potentielles allant de la situation la plus à risque vers la plus sécurisée (pondérée à 100 %). Les étapes du circuit les plus critiques sont l’absence de conciliation, la non-informatisation des prescriptions et l’administration médicamenteuse sans prescription. Dans seulement 2 situations sur 28 (7 %) le circuit extrahospitalier est sécurisé à 100 % et dans 13 cas sur 28 (46 %), un niveau de sécurisation supérieur à 50 % (seuil d’acceptabilité défini) est atteint. Si le choix de la valeur seuil (50 %) et la pertinence d’un tel outil restent critiquables, ce travail préliminaire a permis la mise en évidence des situations les plus à risque, la création d’un groupe de travail pluridisciplinaire et l’élaboration de mesures correctives.

Crop monitoring and appropriate agricultural management practices of elite germplasm will enhance bioenergy’s efficiency. Unmanned aerial systems (UAS) may be a useful tool for this purpose. The objective of this study was to assess the use of UAS with true color and multispectral imagery to predict the yield and total cellulosic content (TCC) of newly created energy cane germplasm. A trial was established in the growing season of 2016 at the Texas A&M AgriLife Research Center in Weslaco, Texas, where 15 energy cane elite lines and three checks were grown on experimental plots, arranged in a complete block design and replicated four times. Four flights were executed at different growth stages in 2018, at the first ratoon crop, using two multi-rotor UAS: the DJI Phantom 4 Pro equipped with RGB camera and the DJI Matrice 100, equipped with multispectral sensor (SlantRange 3p). Canopy cover, canopy height, NDVI (Normalized Difference Vegetation Index), and ExG (Excess Green Index) were extracted from the images and used to perform a stepwise regression to obtain the yield and TCC models. The results showed a good agreement between the predicted and the measured yields (R2 = 0.88); however, a low coefficient of determination was found between the predicted and the observed TCC (R2 = 0.30). This study demonstrated the potential application of UAS to estimate energy cane yield with high accuracy, enabling plant breeders to phenotype larger populations and make selections with higher confidence.

Tendo como base contextual a crise ambiental contemporânea, a qual tem características de crise civilizatória, este trabalho teve como principal objetivo colocar em debate a noção de Desenvolvimento Sustentável (DS), visto que este importante conceito foi politicamente construído e consensuado de forma a ser a principal resposta para a questão ambiental. Dessa maneira, dado que a crise ambiental pede a emergência de um novo paradigma (o qual supere o chamado paradigma da simplificação), que leve em consideração uma mudança de cunho cognitivo, e compreenda o espaço em sua dinâmica de produção e reprodução da vida e em suas múltiplas territorialidades, esta pesquisa buscou analisar a possível constituição da sustentabilidade como este paradigma complexo, ou, ao contrário, se tal noção se resume a uma matriz discursiva que, como tal, obscurece as principais questões que deveriam ser consideradas por um paradigma da complexidade com um, conseqüente, novo aporte teórico-metodológico. Nesse sentido, o caminho metodológico traçado incluiu a discussão das diferentes concepções acerca das noções de matriz discursiva e paradigma, relacionando-se, posteriormente, tais temáticas com a questão ambiental e com a noção de DS em si, em seu viés político e científico. Apesar de dúvidas permanecerem, se considerou que a sustentabilidade parece, realmente, se apresentar muito mais como uma matriz discursiva do que como um paradigma, integrando uma matriz discursiva do meio ambiente. Assim, se pode apontar que o DS se encontra delimitado em um campo institucional específico, com pesquisas e políticas públicas orientadas e influenciadas pelos agentes determinantes hegemônicos de tal campo, como o Banco Mundial, por exemplo. Estes, de acordo com determinada visão de desenvolvimento (como sinônimo de crescimento econômico e se utilizando do viés da economia neoclássica) e da problemática ambiental (relegada a uma questão de gestão ou planejamento ambiental adequado, sem maiores entendimentos com relação a dinâmica territorial em sua totalidade) influenciam os discursos que devem permear o campo ambiental, pautando, inclusive, o conhecimento científico. A noção de DS colocada desta forma não representa, assim, qualquer ruptura com o paradigma da simplificação, sendo apenas uma matriz discursiva que encobre (e desenvolve na prática) o núcleo de tal paradigma, influenciando a práxis dos diversos agentes sociais presentes nos territórios. Como possíveis rupturas com a matriz discursiva do meio ambiente, se procurou apresentar e discutir, também, duas linhas de pensamento, ou coletivos do pensamento, que se apresentam como possíveis novos aportes teórico-metodológicos, condizentes, talvez, com um paradigma da complexidade que leve em conta, principalmente, as noções de totalidade e de complexidade ambiental
With the contextual basis the contemporary environmental crisis, which has characteristics of civilizing crisis, this work aimed to put in discussion the idea of Sustainable Development (SD); following that, this important concept has been politically built and conceived in order to be the main answer to this environmental issue. Therefore, since the environmental crisis asks for the emergence of a new paradigm (which exceeds the so-called paradigm of simplification), that takes into account a change of cognitive mark and take in the space in its dynamics of production and reproduction of life and in their multiple territories. This research sought to check over the possible formation of sustainability as this complex paradigm, or, oppositely, if such notion comes down to a discursive matrix that, as such obscures the mains issues that should be considered by a paradigm of complexity and, consequently, new theoretical and methodological support. In this sense, the trace of methodological approach included the discussion of different conceptions about the notions of discourse and paradigm matrix, relating subsequently such topics to environmental issues and the notion of SD itself in its political and scientific bias. Although doubts remain, it was taken into account that the sustainability seems to really perform much more as a discursive matrix than a paradigm, which integrates a discursive matrix of the environment. Consequently, one can point that the SD is found in a limited specific institutional field, with research and policy oriented and influenced by hegemonic determinant agents of such a field, such as the World Bank, for instance. These, according to certain development vision (as a synonym for economic growth and using the bias of neoclassical economics) and environmental issues (relegated to a management issue or appropriate environmental planning, without further understandings with respect to territorial dynamics in your all) influence the discourses that should pass through the environmental field, guiding even scientific knowledge. The notion of SD placed in this way does not represent, so any break with the paradigm of simplification, just being a discursive matrix that covers (and develops in practice) the core of such paradigm, which influences the practice of various social agents present in the territories. Considering as possible disruptions to the discursive matrix of the environment, an attempt to present and discuss also two schools of thought, or collective thinking, posing as potential new theoretical and methodological contributions, observing perhaps with a paradigm of complexity that takes into account mainly the notions of wholeness environmental complexity

Biagrupamento e coagrupamento são tarefas de mineração de dados que permitem a extração de informação relevante sobre dados e têm sido aplicadas com sucesso em uma ampla variedade de domínios, incluindo aqueles que envolvem dados textuais -- foco de interesse desta pesquisa. Nas tarefas de biagrupamento e coagrupamento, os critérios de similaridade são aplicados simultaneamente às linhas e às colunas das matrizes de dados, agrupando simultaneamente os objetos e os atributos e possibilitando a criação de bigrupos/cogrupos. Contudo suas definições variam segundo suas naturezas e objetivos, sendo que a tarefa de coagrupamento pode ser vista como uma generalização da tarefa de biagrupamento. Estas tarefas, quando aplicadas nos dados textuais, demandam uma representação em um modelo de espaço vetorial que, comumente, leva à geração de espaços caracterizados pela alta dimensionalidade e esparsidade, afetando o desempenho de muitos dos algoritmos. Este trabalho apresenta uma análise do comportamento do algoritmo para biagrupamento Cheng e Church e do algoritmo para coagrupamento de decomposição de valores em blocos não negativos (\\textit{Non-Negative Block Value Decomposition} - NBVD), aplicado ao contexto de dados textuais. Resultados experimentais quantitativos e qualitativos são apresentados a partir das experimentações destes algoritmos em conjuntos de dados sintéticos criados com diferentes níveis de esparsidade e em um conjunto de dados real. Os resultados são avaliados em termos de medidas próprias de biagrupamento, medidas internas de agrupamento a partir das projeções nas linhas dos bigrupos/cogrupos e em termos de geração de informação. As análises dos resultados esclarecem questões referentes às dificuldades encontradas por estes algoritmos nos ambiente de experimentação, assim como se são capazes de fornecer informações diferenciadas e úteis na área de mineração de texto. De forma geral, as análises realizadas mostraram que o algoritmo NBVD é mais adequado para trabalhar com conjuntos de dados em altas dimensões e com alta esparsidade. O algoritmo de Cheng e Church, embora tenha obtidos resultados bons de acordo com os objetivos do algoritmo, no contexto de dados textuais, propiciou resultados com baixa relevância
Biclustering e coclustering are data mining tasks that allow the extraction of relevant information about data and have been applied successfully in a wide variety of domains, including those involving textual data - the focus of interest of this research. In biclustering and coclustering tasks, similarity criteria are applied simultaneously to the rows and columns of the data matrices, simultaneously grouping the objects and attributes and enabling the discovery of biclusters/coclusters. However their definitions vary according to their natures and objectives, being that the task of coclustering can be seen as a generalization of the task of biclustering. These tasks applied in the textual data demand a representation in a model of vector space, which commonly leads to the generation of spaces characterized by high dimensionality and sparsity and influences the performance of many algorithms. This work provides an analysis of the behavior of the algorithm for biclustering Cheng and Church and the algorithm for coclustering non-negative block decomposition (NBVD) applied to the context of textual data. Quantitative and qualitative experimental results are shown, from experiments on synthetic datasets created with different sparsity levels and on a real data set. The results are evaluated in terms of their biclustering oriented measures, internal clustering measures applied to the projections in the lines of the biclusters/coclusters and in terms of generation of information. The analysis of the results clarifies questions related to the difficulties faced by these algorithms in the experimental environment, as well as if they are able to provide differentiated information useful to the field of text mining. In general, the analyses carried out showed that the NBVD algorithm is better suited to work with datasets in high dimensions and with high sparsity. The algorithm of Cheng and Church, although it obtained good results according to its own objectives, provided results with low relevance in the context of textual data

The cartilage damage and destruction are common in osteoarthritis (OA) and are associated with elevated levels of matrix metalloproteinases (MMPs), proteinases that can degrade all components of the extracellular matrix (ECM). The objective was to study the effect of low level laser therapy (LLLT) at 50mW and 100mW in joint damage evaluated by histopathological analysis, and protein expression of metalloproteinases (MMPs) 2 and 9 in the articular lavage. We used 60 male Wistar rats randomly divided into 4 groups of 15 animals each: a control group, an injury group, and two treated groups, one with LLLT 50mW and other with 100mW. The animals underwent OA induction (papain solution 4%) and, on the euthanasia day was collected the articular lavage, which was immediately centrifuged and the supernatant saved for analysis of protein expression by Western blot. The material was stained with hematoxylin and eosin for histopathologic description and Picrosirius Red, to estimate the percentage of collagen fibers. As a result, it was observed that both laser groups were efficient on tissue repair, decreasing the expression of collagen type III and increasing type I at all the experimental times, however, the group LLLT 50mW was better in reducing MMP - 9 in relation to the LLLT 100mW group in 21 days. In conclusion, LLLT 50 mW was more efficient on modulating matrix metalloproteinases and repair of the cartilaginous tissue.
A lesão da cartilagem e a sua destruição são comuns em osteoartrite (OA) e estão associadas com níveis elevados de metaloproteinases de matriz (MMPs), proteinases que podem degradar todos os componentes da matriz extracelular (ECM). O objetivo foi estudar o efeito do laser de baixa intensidade (LBI) com 50mW e 100mW em lesões articulares por meio da análise histopatológica, bem como pela expressão proteíca de metaloproteinases 2 e 9 no lavado articular. Utilizou-se 60 ratos Wistar machos, distribuídos aleatoriamente em 4 grupos de 15 animais, sendo: um grupo controle; um grupo lesão, e dois grupos tratados, um com LBI de 50mW, e outro com LBI de 100mW. Os animais foram submetidos a OA (solução de papaína a 4%) e, no dia da eutanásia, coletou-se o lavado articular, que foi imediatamente centrifugado e o sobrenadante armazenado para análise de expressão protéica por Western Blot. O material foi corado com HE para a descrição histopatológica e Picrosirius Red, para estimar o percentual de fibras colágenas. Como resultado, observou-se que os dois grupos laser foram eficientes na reparação tecidual, diminuindo a expressão de colágeno tipo III e aumentando a do tipo I em todos os tempos experimentais, no entanto, o grupo LBI 50mW foi melhor em relação à redução da metaloproteinase 9 em relação ao grupo LBPI 100mW em 21 dias. Podemos concluir que o LBI 50 mW foi mais eficiente na modulação de metaloproteinases de matriz e reparação do tecido cartilaginoso.

E' evidenziata l'importanza della raccolta differenziata e della scelta delle matrici compostabili nell'ottimizzazione di questa biotecnologia spontanea per il trattamento di rifiuti e reflui organici putrescibili. E' sottolineato, inoltre, come una corretta gestione del processo permetta di valorizzare residui di varia natura trasformandoli in un buon compost, prodotto valido dal punto di vista agronomico e ambientale. Nella parte finale della relazione verrà inoltre descritto un impianto di compostaggio, presente nel territorio regionale, la Nuova Geovis di Sant'Agata Bolognese e dal punto di vista applicativo, verrà costruito un modello, che permetta di legare l'andamento della temperatura all'andamento dell'IRD, Indice di Respirazione Dinamico, attraverso dati raccolti presso l'impianto, relativi ovviamente a Indice di Respirazione Dinamico (IRD) e temperatura. Questo anche per valutare il corretto del processo stesso.

Annotation:

A sign pattern matrix is a matrix whose entries are from the set {+,-,0}. For a real matrix B, sgn(B) is the sign pattern matrix obtained by replacing each positive(respectively, negative, zero) entry of B by + (respectively, -, 0). For a sign pattern matrix A, the sign pattern class of A, denoted Q(A), is defined as {B: sgn(B) = A}. An n by n sign pattern matrix A requires all distinct eigenvalues if every real matrix whose sign pattern is represented by A has n distinct eigenvalues. In this thesis, a number of sufficient and/or necessary conditions for a sign pattern to reuiqre all distinct eigenvalues are reviewed. In addition, for n=2 and 3, the n by n sign patterns that require all distinct eigenvalues are surveyed. We determine most of the 4 by 4 irreducible sign patterns that require four distinct eigenvalues.

Coagrupamento é uma estratégia para análise de dados capaz de encontrar grupos de dados, então denominados cogrupos, que são formados considerando subconjuntos diferentes das características descritivas dos dados. Contextos de aplicação caracterizados por apresentar subjetividade, como mineração de texto, são candidatos a serem submetidos à estratégia de coagrupamento; a flexibilidade em associar textos de acordo com características parciais representa um tratamento adequado a tal subjetividade. Um método para implementação de coagrupamento capaz de lidar com esse tipo de dados é a fatoração de matrizes. Nesta dissertação de mestrado são propostas duas estratégias para coagrupamento baseadas em fatoração de matrizes não-negativas, capazes de encontrar cogrupos organizados com sobreposição de colunas em uma matriz de valores reais positivos. As estratégias são apresentadas em termos de suas definições formais e seus algoritmos para implementação. Resultados experimentais quantitativos e qualitativos são fornecidos a partir de problemas baseados em conjuntos de dados sintéticos e em conjuntos de dados reais, sendo esses últimos contextualizados na área de mineração de texto. Os resultados são analisados em termos de quantização do espaço e capacidade de reconstrução, capacidade de agrupamento utilizando as métricas índice de Rand e informação mútua normalizada e geração de informação (interpretabilidade dos modelos). Os resultados confirmam a hipótese de que as estratégias propostas são capazes de descobrir cogrupos com sobreposição de forma natural, e que tal organização de cogrupos fornece informação detalhada, e portanto de valor diferenciado, para as áreas de análise de agrupamento e mineração de texto
Coclustering is a data analysis strategy which is able to discover data clusters, known as coclusters. This technique allows data to be clustered based on different subsets defined by data descriptive features. Application contexts characterized by subjectivity, such as text mining, are candidates for applying coclustering strategy due to the flexibility to associate documents according to partial features. The coclustering method can be implemented by means of matrix factorization, which is suitable to handle this type of data. In this thesis two strategies are proposed in non-negative matrix factorization for coclustering. These strategies are able to find column overlapping coclusters in a given dataset of positive data and are presented in terms of their formal definitions as well as their algorithms\' implementation. Quantitative and qualitative experimental results are presented through applying synthetic datasets and real datasets contextualized in text mining. This is accomplished by analyzing them in terms of space quantization, clustering capabilities and generated information (interpretability of models). The well known external metrics Rand index and normalized mutual information are used to achieve the analysis of clustering capabilities. Results confirm the hypothesis that the proposed strategies are able to discover overlapping coclusters naturally. Moreover, these coclusters produced by the new algorithms provide detailed information and are thus valuable for future research in cluster analysis and text mining

Annotation:

Over the past decades, a great body of theoretical and mathematical work has been devoted to random-matrix descriptions of open quantum systems. This chapter reviews the physical origins and mathematical structures of the underlying models, and collects key predictions which give insight into the typical system behaviour. In particular, the aim is to give an idea how the different features are interlinked. The chapter mainly focuses on elastic scattering but also includes a short detour to interacting systems, which are motivated by the overarching question of ergodicity. The first sections introduce general notions from random matrix theory, such as the 10 universality classes and ensembles of Hermitian, unitary, positive-definite, and non-Hermitian matrices. The following sections then review microscopic scattering models that form the basis for statistical descriptions, and consider signatures of random scattering in decay, dynamics, and transport. The last section touches on Anderson localization and localization in interacting systems.

Although autogenous arteriovenous fistula creation is the gold-standard dialysis access, catheters represent between 40% and 60% of dialysis access in the United States. Catheters are placed for a variety of reasons, commonly as temporary access for acute renal failure or as a bridge to a more permanent access in patients with end-stage renal disease. Fibrin sheaths represent a heterogeneous matrix of cells and debris that form around catheters and are a known common cause of catheter failure and central venous stenosis. Their formation is ubiquitous in the dialysis population, occurring with 80–100% of catheters within 1 week of implantation. This chapter presents several techniques for the management of the fibrin sheath—the traditional catheter stripping technique, the internal catheter stripping technique, and the fibrin sheath angioplasty technique.

Annotation:

Calcium pyrophosphate (CPP) dihydrate crystals form extracellularly. Their formation requires sufficient extracellular inorganic pyrophosphate (ePPi), calcium, and pro-nucleating factors. As inorganic pyrophosphate (PPi) cannot cross cell membranes passively due to its large size, ePPi results either from hydrolysis of extracellular ATP by the enzyme ectonucleotide pyrophosphatase/phosphodiesterase 1 (also known as plasma cell membrane glycoprotein 1) or from the transcellular transport of PPi by ANKH. ePPi is hydrolyzed to phosphate (Pi) by tissue non-specific alkaline phosphatase. The level of extracellular PPi and Pi is tightly regulated by several interlinked feedback mechanisms and growth factors. The relative concentration of Pi and PPi determines whether CPP or hydroxyapatite crystal is formed, with low Pi/PPi ratio resulting in CPP crystal formation, while a high Pi/PPi ratio promotes basic calcium phosphate crystal formation. CPP crystals are deposited in the cartilage matrix (preferentially in the middle layer) or in areas of chondroid metaplasia. Hypertrophic chondrocytes and specific cartilage matrix changes (e.g. high levels of dermatan sulfate and S-100 protein) are related to CPP crystal deposition and growth. CPP crystals cause inflammation by engaging with the NALP3 inflammasome, and with other components of the innate immune system, and is marked with a prolonged neutrophilic inflitrate. The pathogenesis of resolution of CPP crystal-induced inflammation is not well understood.

El estudio de los territorios y las fronteras conduce de manera irremisible a hablar de estructuras configuradas históricamente en el largo tiempo. Este libro surge desde distintas miradas con la pretensión de incursionar en el campo del conocimiento sociohistórico e historiográfico mediante trabajos relacionados con Mesoamérica desde su inicial configuración prehispánica cultural y arqueológica hasta su dimensión histórica, pasando por diferentes etapas hasta llegar a la época contemporánea. Se presentan análisis de territorios cargados de representación simbólica principalmente a partir de las culturas originarias, a la vez que se consideran procesos de apropiación territorial enmarcados en las fronteras, en las que se encuentran ancladas añejas disputas que arrancan en la división político-administrativa de las antiguas colonias americanas; posteriormente, el periodo republicano surgido tras las independencias dio lugar a la invisibilización de los pueblos que presentaban matrices culturales diferentes, lo que condujo al establecimiento de relaciones de dominación de unos individuos sobre otros basadas en un pacto que definió una territorialidad y una soberanía propias. En cuanto al período contemporáneo, en este libro se ponen de relieve algunos acontecimientos ocurridos en el siglo XX y lo que va del siglo XXI que han trascendido las fronteras nacionales, como la incidencia de la política exterior estadounidense, la actuación de los organismos de seguridad y los grupos paramilitares en Guatemala y en México en lo que podría considerarse una contrainsurgencia regional, o la consideración de El Salvador como “la más extendida república pretoriana” de América Latina, que abrió el espacio para que los militares se mantuvieran desde 1931 hasta 1982.

Tension-compression fatigue behavior of a non-oxide ceramic composite with a multilayered matrix was investigated at 1200°C in laboratory air. The composite was produced via chemical vapor infiltration (CVI). The composite had an oxidation inhibited matrix, which consisted of alternating layers of silicon carbide and boron carbide and was reinforced with laminated Hi-Nicalon™ fibers woven in an eight-harness-satin weave (8HSW). Fiber preforms had pyrolytic carbon fiber coating with boron carbon overlay applied. Tension-compression fatigue behavior was studied for fatigue stresses ranging from 80 to 200 MPa at a frequency of 1.0 Hz. The R ratio (minimum stress to maximum stress) was −1.0. Fatigue run-out was defined as 2×105 cycles. Fatigue limit was 80 MPa. Specimens that achieved fatigue run-out were subjected to tensile tests to failure to characterize the retained tensile properties. The material retained 100% of its tensile strength. Reductions in tensile modulus and in compressive modulus were negligible. Composite microstructure, as well as damage and failure mechanisms were investigated.

Uma S-Box (caixa de substituição) deve ter pelo menos valores ótimos para não linearidade (N L), uniformidade diferencial e grau algébrico. Segundo a literatura, uma S-Box criptograﬁcamente forte deve ter N L > 100. O AES (Advanced Encryption Standard) usa uma matriz binária não singular S para construir sua S-Box. Muitos trabalhos escolhem S em aproximadamente 262 matrizes não singulares ou constroem S-Box aleatoriamente, sem garantir N L > 100. Neste trabalho, identiﬁcamos que S pode ser estudada como uma matriz de adjacência (A(G)) de um multigrafo de Ramanujan e veriﬁcamos esta relação com outras A(G) do tipo rotacionais. Dessa forma, reduzimos a busca por S para a ordem de 1011 e construímos S-Boxes com N L > 100.

Most engine health monitoring systems used for land based systems are based on steady state operation. Diagnostic analysis has traditionally been conducted under steady state conditions with on-line systems tending to concentrate on map based performance diagnostics using pattern analysis, fault matrices or expert systems. Transient analysis is a relatively a new technique and is being applied to some aeroengines. There is significant diagnostic content in turbine startup and shutdown data and in data obtained during power or speed changes. This data can be captured if an automatic on-line system is employed. This paper provides an overview of the use of both performance and mechanical transient analysis as a means to detect gas turbine problems. The paper covers the need for transient analysis and covers transient analysis techniques. Examples and a discussion of how transient analysis can be integrated within an existing on-line monitoring system is made.

This paper reflects the findings of the first phase of the REJUVENATE project, which set out to understand and map approaches to integrating children, youth, and community participation in child rights initiatives. We did this through a scoping of existing practitioner and academic literature (developing a project-based literature review matrix), a mapping of key actors, and the development of a typology of existing approaches. All three of these elements were brought together into a ‘living archive’, which is an evolving database that currently comprises 100 matrices, and a ‘collection’ of key field practitioners (many of whom we have interviewed for this project). In this paper we: (1) present a user-friendly summary of the existing tradition of substantive children’s participation in social change work; (2) share case studies across various sectors and regions of the world; (3) highlight ongoing challenges and evidence gaps; and (4) showcase expert opinions on the inclusion of child rights and, in particular, child/youth-led approaches in project-based work.

Annotation:

Herein the matrix effects on the kinetics of aqueous photolysis for the individual munitions constituents of IMX-101: nitroguanidine (NQ), dinitroanisole (DNAN), and nitrotriazolone (NTO) are reported along with the environmentally relevant kinetics and quantum yields. Photolysis potentially represents a major degradation pathway for these munitions in the environment and further understanding the complex matrices effects on photolytic kinetics was needed. Aqueous systems are of particular interest due to the high solubility of NQ (3,800 ppm) and NTO (16,642 ppm) compared to the traditional munitions trinitrotoluene (TNT, 100.5 ppm) and 1,3,5-trinitro-1,3,5-triazine (RDX, 59.9 ppm). Environmental half-lives (and quantum yields) were found to be 0.44 days, 0.83 days, and 4.4 days for NQ, DNAN, and NTO, respectively, under natural sunlight. In laboratory experiments using nominally 300 nm bulbs in a merry-go-round style reactor in DI water the relative rate of photolysis for the three munitions constituents followed the same order NQ > DNAN > NTO, where DNAN and NTO reacted 57 and 115 times more slowly, respectively, than NQ. In the various environmentally relevant matrices tested in the laboratory experiments NQ was not significantly affected, DNAN showed a faster degradation with increasing ionic strength, and NTO showed a modest salinity and pH dependence on its rate of photolysis.
