Adaptive finite‐time stabilization of nonlinearly parameterized systems subject to mismatching disturbances
Authors: Min Huifang , Xu Shengyuan , Gu Jason , Zhang Zhengqiang 
Published: May 2019

SummaryThis paper gives a first try to the finite‐time control for nonlinear systems with unknown parametric uncertainty and external disturbances. The serious uncertainties generated by unknown parameters are compensated by skillfully using an adaptive control technique. Exact knowledge of the upper bounds of the disturbances is removed by employing a disturbance observer–based control method. Then, based on the disturbance observer–based control, backstepping technique, finite‐time adaptive control, and Lyapunov stability theory, a composite adaptive state‐feedback controller is strictly designed and analyzed, which guarantees the closed‐loop system to be practically finite‐time stable. Finally, both the practical and numerical examples are presented and compared to demonstrate the effectiveness of the proposed scheme.

AbstractWe previously demonstrated that intracardiac delivery of autologous peripheral blood-derived CD34+ stem cells (SCs), mobilized by granulocyte-colony stimulating factor (G-CSF) and collected by leukapheresis after myocardial infarction, structurally and functionally repaired the damaged myocardial area. When used for cardiac indication, CD34+ cells are now considered as Advanced Therapy Medicinal Products (ATMPs). We have industrialized their production by developing an automated device for ex vivo CD34+-SC expansion, starting from a whole blood (WB) sample. Blood samples were collected from healthy donors after G-CSF mobilization. Manufacturing procedures included: (a) isolation of total nuclear cells, (b) CD34+ immunoselection, (c) expansion and cell culture recovery in the device, and (d) expanded CD34+ cell immunoselection and formulation. The assessment of CD34+ cell counts, viability, and immunophenotype and sterility tests were performed as quality tests. We established graft acceptance criteria and performed validation processes in three cell therapy centers. 59.4 × 106 ± 36.8 × 106 viable CD34+ cells were reproducibly generated as the final product from 220 ml WB containing 17.1 × 106 ± 8.1 × 106 viable CD34+ cells. CD34+ identity, genetic stability, and telomere length were consistent with those of basal CD34+ cells. Gram staining and mycoplasma and endotoxin analyses were negative in all cases. We confirmed the therapeutic efficacy of both CD34+-cell categories in experimental acute myocardial infarct (AMI) in immunodeficient rats during preclinical studies. This reproducible, automated, and standardized expansion process produces high numbers of CD34+ cells corresponding to the approved ATMP and paves the way for a phase I/IIb study in AMI, which is currently recruiting patients.

System Dynamics Review and publications 1985–2017: analysis, synthesis and contributions
Authors: Torres Juan P. 
Published: May 2019

AbstractSystem Dynamics Review (SDR) is an important journal for the system dynamics field and its researchers. This article offers a systematic review of the system dynamics articles published in SDR and other related academic journals between 1985 and 2017. The study classifies the material by using a bibliometric analysis of 498 articles in SDR and 943 articles in other journals that are included in the Web of Science database. The results suggest that the most cited authors within SDR have published research in three broad areas: (i) model validity (confidence), tests, and other similar formal procedures; (ii) the modeling of dynamic problems of wide interest; and (iii) group model building. In other journals, an additional stream of system dynamics research proves to be highly influential. This stream focuses on better understanding and improving the process of dynamic decision making, addressing topics such as organizational learning and feedback misperceptions.© 2019 System Dynamics Society
Maternal exposure causes mitochondrial dysfunction in brain, liver, and heart of mouse fetus: An explanation for perfluorooctanoic acid induced abortion and developmental toxicity
Authors: Salimi Ahmad , Nikoosiar Jahromi Mahnia , Pourahmad Jalal 
Published: May 2019

AbstractPerfluorooctanoic acid (PFOA) is an octanoic acid and is found in wildlife and humans. We have investigated mitochondrial toxicity in isolated mitochondria from, placenta, brain, liver, and heart after oral exposure with PFOA in mice during gestational days (7‐15). Histopathological examination and mitochondrial toxicity parameters were assayed. Results indicated that PFOA decreased the weight of the fetus and placenta, the length of the fetus and the diameter of the placenta, dead fetuses and dead macerated fetuses in treated mice with 25 mg/kg. Histopathological examination showed that PFOA induced pathological abnormalities in liver, brain, heart, and placenta. Also, PFOA induced mitochondria toxicity in brain, liver, heart of mouse fetus. Our results indicate that PFOA up to 20 mg/kg exposure adversely affect embryofetal/developmental because for mitochondria dysfunction. These results suggested that mitochondrial dysfunction induced by PFOA in liver, heart, and brain lead to developmental toxicity and abnormality in tissues.
Control of skunk-vine (Paederia foetidaL.) with preemergence and postemergence herbicides in central Florida during the winter season
Authors: Marble S. Christopher , Chandler Annette 
Published: May 2019

AbstractSkunk-vine (Paederia foetidaL.) is an invasive vine native to eastern and southern Asia and is widely distributed in Florida, Hawaii, and other southeastern U.S. states; however, little research has focused on herbicide control. Greenhouse and field experiments were conducted to determine efficacy of aminocyclopyrachlor, aminopyralid, fluroxypyr, glyphosate, imazapic, triclopyr amine, and triclopyr ester at low and high labeled rates when foliar applied toP. foetidaat various growth stages in greenhouse experiments. Longer-term control was evaluated in field experiments in central Florida using the same herbicides. PRE herbicides labeled for use in landscape plantings, including dimethenamid-P, flumioxazin, indaziflam, isoxaben, and prodiamine, were also evaluated in greenhouse trials by seeding containers withP. foetidaseed. In greenhouse experiments, POST herbicides, including aminocyclopyrachlor, aminopyralid, glyphosate, both triclopyr formulations, and the high rate of fluroxypyr (0.24 kg ae ha−1), provided >90% control across all growth stages at 4 mo after treatment with no regrowth observed. Imazapic provided 49% to 89% control, with efficacy decreasing withP. foetidasize, and generally provided less control than other treatments. Field experiments confirmed results from greenhouse studies. In PRE trials, flumioxazin and prodiamine provided better control than all other PRE herbicides evaluated, reducing shoot weights by 99% and 84%, respectively, compared with nontreated controls. Our data suggest all herbicides evaluated POST could potentially be used to manageP. foetida, although less control was achieved with imazapic compared with other herbicides. Further research is needed to determine herbicide efficacy on more mature plants and to develop application methods that would be less injurious to non-target vegetation. In landscapes, flumioxazin or prodiamine could be used for PRE control, but POST options that are labeled for landscape use should be identified in future research.
Bone histology of Azendohsaurus laaroussii: Implications for the evolution of thermometabolism in Archosauromorpha
Authors: Cubo Jorge , Jalil Nour-Eddine 
Published: May 2019

AbstractThis paper is aimed at constraining the phylogenetic frame of the acquisition of endothermy by Archosauromorpha. We analyzed the bone histology of Azendohsaurus laaroussii. Stylopodial and zeugopodial bones show three tissue types: (1) avascular lamellar zonal bone formed at low growth rates; (2) a scaffold of parallel-fibered bone containing either small primary osteons or simple vascular canals; and (3) fibrolamellar bone formed at high growth rates. We used quantitative histology to infer the thermometabolic regime of this taxon. We define endothermy as the presence of any mechanism of nonshivering thermogenesis that increases both body temperature and resting metabolic rate. Thus, estimating the resting metabolic rate of an extinct organism may be a good proxy to infer its thermometabolic regime (endothermy vs. ectothermy). High resting metabolic rates have been shown to be primitive for the clade Prolacerta–Archosauriformes. Therefore, we inferred the resting metabolic rates of A. laaroussii, a sister group of this clade, and of 14 extinct related taxa, using phylogenetic eigenvector maps. All the inferences obtained are included in the range of variation of resting metabolic rates measured in mammals and birds, so we can reasonably assume that all these taxa (including Azendohsaurus) were endotherms. A parsimony optimization of the presence of endothermy on a phylogenetic tree of tetrapods shows that this derived character state was acquired by the last common ancestor of the clade Azendohsaurus–Archosauriformes and that there is a reversion in Crocodylia.
Introduction of the Boxtel Formation and implications for the Quaternary lithostratigraphy of the Netherlands

Published: May 2019

AbstractApplication of the traditional lithostratigraphic framework to subdivide the Middle- and Upper-Quaternary locally-derived fine-grained deposits in the Netherlands is problematic. Deposits of many formations cannot be distinguished from each other based on lithological characteristics and stratigraphie position alone. To overcome this problem, we present a new, well-defined lithostratigraphy for these deposits, based on detailed research in the central part of the Roer Valley Graben. This area contains an up to 35 m-thick sedimentary record of Middle- and Upper-Quaternary sand, loam and peat deposits. These have mainly been formed by aeolian and small-scale fluvial processes and have been preserved as a result of tectonic subsidence. The traditional lithostratigraphic subdivision of these deposits into three formations (Eindhoven Formation, Asten Formation and Twente Formation) was based on a combination of litho-, bio- and chronostratigraphic evidence and the presumed widespread presence of a horizon of organic-rich interglacial sediments of Eemian age. To avoid intermingling of criteria regarding lithological characteristics, genesis and age, we now incorporate all fine-grained sediments into the new Boxtel Formation. The implications for the lithostratigraphic framework in other parts of the country are explored and discussed. Eight lithostratigraphic members are introduced that describe the most characteristic parts of the formation. To fully illustrate the sedimentary sequence in the Roer Valley Graben, two new members are defined here. The Best Member incorporates alternating floodloam deposits and sandy aeolian deposits in the lower part of the Boxtel Formation. The Liempde Member includes reworked aeolian loess and sandy loess deposits (‘Brabant loam’) that occur in the upper part of the sedimentary sequence.
Downstream changes of meandering styles in the lower reaches of the River Vecht, the Netherlands
Authors: Wolfert H.P. , Maas G.J. 
Published: May 2019

AbstractThe morphodynamics of the lower River Vecht, the Netherlands, and the influence of geomorphological setting and bank composition on meander migration were studied by means of reconstructing the pre-channelization landform configuration on a scale of 1 : 25,000, using historical maps from 1720, 1850 and 1890 A.D. and other data.A downstream sequence of reaches was observed, each with a typical fluvial style and channel migration rate: (a) a narrow meander belt and a highly sinuous channel with intermediate migration rate, in the middle of an extensive floodbasin; (b) a wide meander belt and high rates of lateral channel migration, especially where large meanders impinged upon valley bluffs, as part of an incised setting; (c) a low sinuosity, embanked channel with low rates of downstream migration because of confinement by dikes, occurring in an inland delta with sandy sediments.Local variation in meander migration rates was observed within reach B. This was caused by the spatial variability of bank resistance as reflected by the width-depth ratio of the channel and the silt-clay ratios of deposits. River banks are: 1) very erodible when consisting of channel deposits, aeolian dune deposits or when coarse fluvio-periglacial deposits occur at their base; 2) erodible when dominated by overbank deposits or aeolian sand sheet deposits; 3) resistant when a plaggen-layer is exposed; and 4) very resistant when dominated by floodbasin deposits.These implications of meander variability enable to assess the effects of the rehabilitation of the meandering process.
Opposite hysteresis of sand and gravel transport upstream and downstream of a bifurcation during a flood in the River Rhine, the Netherlands

Published: May 2019

AbstractAt river bifurcations water and sediment is divided among the downstream branches. Prediction of the sediment transport rate and division thereof at bifurcations is of utmost importance for understanding the evolution of the bifurcates for short-term management purposes and for long-term fluvial plain development. However, measured sediment transports in rivers rarely show a uniquely determined relation with hydrodynamic parameters. Commonly a hysteresis is observed of transport rate as a function of discharge or shear stress which cannot be explained with the standard sediment transport predictor approach. The aim of this paper is to investigate the causes of hysteresis at a bifurcation of the lower Rhine river, a meandering river with stable banks, large dunes during flood, and poorly sorted bed sediment. The hydrodynamics and bed sediment transport were measured in detail during a discharge wave with a recurrence interval larger than 10 years. Surprisingly, the hysteresis in bedload against discharge was in the opposite direction upstream and downstream of the bifurcation. The upstream clockwise hysteresis is caused by the lagging development of dunes during the flood. The counter-clockwise hysteresis downstream of the bifurcation is caused by a combination of processes in addition to dune lagging, namely 1) formation of a scour zone upstream of the bifurcation, causing a migrating fine sediment wave, and 2) vertical bed sorting of the bed sediment by dunes with avalanching lee-sides, together leading to surface-sediment fining and increased transport during and after the flood. These findings lead to challenges for future morphological models, particularly for bifurcations, which will have to deal with varying discharge, sediment sorting in the channel bed, lagging dunes and related hydraulic roughness.
Do music festival communities address environmental sustainability and how? A Scottish case study
Authors: Brennan Matt , Scott Jo Collinson , Connelly Angela , Lawrence Gemma 
Published: May 2019

AbstractThis article discusses the findings of an Arts and Humanities Research Council project researching how music festival communities in Scotland can address issues of environmental sustainability and climate change. It investigates how music festival communities are constructed with a focus on what role, if any, they might play in responding to the global challenge of environmental sustainability. Using music festivals in Scotland as a case study, we employed a variety of research methods to interrogate different constituents in music festival communities about their views and behaviours regarding climate change and environmental sustainability. These included festival audiences via onsite questionnaires; festival organisers and promoters via interviews and focus groups; and musicians via creative practice-led research. We conclude that rather than necessarily being a site for progressive or utopian socio-cultural experimentation (as they are occasionally portrayed in festival literature), music festival communities engage in complex and often contradictory behaviours when it comes to responding to – and making sense of – their own complicity in social challenges such as climate change.
A sound track to ecological crisis: tracing guitars all the way back to the tree
Authors: Gibson Chris 
Published: May 2019

AbstractAnalyses of music and environment are proliferating, yet new conceptions are needed to make sense of growing ecological crisis in the Anthropocene. From an empirical project tracing guitars all the way back to the tree, I argue for deeper conceptual and empirical integration of music into the material and visceral processes that constitute ecological crisis itself. Musicians are not only inspired by environmental concerns for compositional or activist purposes. They are entangled in environmental crisis through material and embodied relations with ecosystems, especially via the musical instruments we depend upon. I foreground three ‘more-than-musical’ themes to make sense of unfurling forces: materiality, corporeality and volatility. Musical instruments are gateway objects that invite contemplation of material and corporal relations. Such relations bind together musicians and non-human others. Material and corporeal relations with increasingly threatened upstream forests, and endangered tree species, are being confronted and reconfigured. In the context of ecological crisis, guitars do much more than make pleasing acoustic sounds. Via guitars we co-generate, with non-human others, a sound track of crisis both melancholy and hopeful.
Retour à Waterloo. Histoire militaire et théorie des jeux
Authors: Mongin Philippe 
Published: May 2019

RésuméL’article propose d’appliquer à l’histoire militaire et, plus précisément, aux récits de campagne à la manière de Clausewitz, les modèles venus des théories mathématiques des jeux et de la décision. Il illustre la méthode en revenant sur la campagne de Waterloo et les hypothèses qu’a suscitées l’échec de Napoléon chez les historiens. Ils ne s’accordent pas sur le sens rationnel de la décision qu’il prit le 17 juin 1815 de lancer le détachement de Grouchy contre les Prussiens battus le 16 à Ligny, mais la théorie des jeux permet dans une certaine mesure de les départager. Une fois obtenu ce résultat, l’article se développe sur le plan réflexif et méthodologique. Il compare les objections qu’on peut faire à sa formalisation et celles déjà élevées contre l’école du « récit analytique », puis amplifiant ses réponses, il examine le conflit des modèles mathématisés du choix rationnel avec le récit, mode d’expression canonique de l’historien. La réconciliation qu’il propose finalement se fonde sur une analyse des concepts de narration, de récit explicatif et de modèle.
Pouvoir et propriété dans l’entreprise. Pour une histoire internationale des sociétés à responsabilité limitée
Authors: Guinnane Timothy W. , Harris Ron , Lamoreaux Naomi R. , Rosenthal Jean-Laurent 
Published: May 2019

RésuméUne longue tradition admet la supériorité de la société anonyme comme forme d’organisation. Une autre, plus récente, estime que les systèmes juridiques anglo-américains donnent aux investisseurs une meilleure protection que les systèmes de droit civil. Cet article remet en cause ces deux idées. Il s’intéresse à l’introduction des sociétés à responsabilité limitée en France, en Allemagne, au Royaume-Uni et aux États-Unis à la fin du XIXe siècle et au XXe siècle. Ces sociétés combinent les avantages de la personnalité juridique et de la société par actions avec des règles de gouvernance interne flexibles. Sont ainsi évités la menace de dissolution inhérente aux sociétés en partenariat et le danger propre aux sociétés anonymes d’une oppression des minoritaires. La SARL fut introduite avec succès d’abord en Allemagne, régie par un code juridique, et en dernier lieu seulement aux États-Unis, pays où domine la common law. La SARL fut partout privilégiée par les sociétés petites et moyennes, même dans les pays où les sociétés anonymes étaient faciles et peu coûteuses à créer et où les règles juridiques les régissant étaient assez légères.
Anthropologie du totalitarisme. Lectures de Vincent Descombes et Louis Dumont
Authors: de Lara Philippe 
Published: May 2019

RésuméY a-t-il une anthropologie du totalitarisme ? Louis Dumont a peu écrit sur le sujet, mais y portait un intérêt constant dans ses travaux. L’article montre que la théorie du totalitarisme est un problème crucial pour une oeuvre consacrée à une perspective comparative sur les sociétés modernes : le totalitarisme est selon Dumont « une maladie de la société moderne », et le totalitarisme et la modernité relèvent du même cadre d’analyse, « l’hybridation »de l’individualisme et du holisme. La première partie présente l’anthropologie de la modernité selon Dumont et sa portée philosophique, telle qu’elle apparaît dans une discussion avec Vincent Descombes. La deuxième partie présente et évalue les hypothèses d’une anthropologie du totalitarisme en les comparant à la théorie politique classique de Hannah Arendt.
La mer Égée au xviiesiècle: Parcours, liens familiaux et recomposition sociale
Authors: Sinarellis Maroula 
Published: May 2019

RésuméLa Méditerranée orientale forme un espace de relations d’une grande plasticité, structuré par d’importants déplacements d’individus et de familles qui affectent considérablement l’univers insulaire. Le passage de la domination latine au pouvoir ottoman constitue, entre la dernière décennie du xviesiècle et tout au long du xviiesiècle, un long processus marqué par l’aliénation des domaines seigneuriaux, la préservation des terres acquises avant l’arrivée des Ottomans, le renforcement de l’institution communautaire, la formation de nouveaux réseaux marchands, etc. Ce texte essaye de saisir les mécanismes de ces phénomènes par l’étude des parcours géographiques qui représentent un aspect de la mobilité sociale. La documentation notariale a permis de reconstituer toute sorte de liens entre familles traditionnelles et nouvellement arrivées (alliances, acquisition de terres, héritages, associations, différentes formes de solidarité et de conflits, etc.), ainsi que de mouvements croisés entre les îles. Entre ces liens et ces mouvements s’est construit une importante recomposition des élites insulaires. Cette modification du paysage social est suivie à travers, d’une part, l’histoire de deux familles et, de l’autre, le voyage en Italie d’un groupe d’étudiants. La notabilité des premières est le produit d’une intense mobilité spatiale, tandis que les déplacements des seconds mettent en évidence l’ampleur des parcours géographiques et l’apparition d’un nouveau profil de notable.
