    It is sometimes the case that a theory proposes that the population means on two variables should have the same rank order across a set of experimental conditions. This paper presents a test of this hypothesis. The test statistic is based on the coupled monotonic regression algorithm developed by the authors. The significance of the test statistic is determined by comparison to an empirical distribution specific to each case, obtained via non-parametric or semi-parametric bootstrap. We present an analysis of the power and Type I error control of the test based on numerical simulation. Partial order constraints placed on the variables may sometimes be theoretically justified. These constraints are easily incorporated into the computation of the test statistic and are shown to have substantial effects on power. The test can be applied to any form of data, as long as an appropriate statistical model can be specified.free access is valid until January 8, 2016:http://authors.elsevier.com/a/1S3XC53naPWGhFunding agencies: Australian Research Council [0877510, 0878630, 110100751, 130101535]; National Science Foundation [1256959]; Linkoping University</p

    Improvement of modern technical systems and technologies. Increasing the productivity of modern agricultural machines with increasing their weight, which leads, in the course of their work, to a significant compaction of the soil. The heterogeneity of the soil, as a bearing surface, causes not adjustable fluctuations in the workplace, which makes automation of the application of robotics more difficult. Modern solutions to the problems of reducing the negative impact on the soil, increasing the permeability of aggregates due to the reconstruction of the propulsors do not give the proper effect. More cardinally solve these problems, as well as the ability to implement automation and robotics bridge systems such as ABAC, moving along rail tracks, AASP on vertical piles and point gravel-halide supports with concrete platforms. The most promising of these is the AAS platform, which is a 30x10 m bridge structure that moves by step-by-step extension, the beams onto 3 subsequent pads located 10 m away. After entering the new position of the bridge platform, along the long 30-meter span beams Moves the work-technological module with a set of working elements, performing the programmed operations. Thus, in the AASP bridge system under consideration, the soil area subjected to compaction at reference points is just over 1% of the 70% protraction of modern machines. Compared to the ABAC system, moving along railways, the equipment of point supports is much less expensive and requires insignificant operating costs. At the same time, the rigidity of AASP design ensures stable operation of technological mechanisms in a programmed robotic mode with a minimum of unproductive energy costs associated with movement

    The article describes transformation of the ideology of liberalism and the associated practices of economic domination at the transition stage from the socio-philosophical Modern paradigm to Postmodern paradigm.Aim. Identify the link between the rhetoric of modern liberalism, Postmodern paradigms and trends in the evolution of the world economic system.Tasks. Consider the historical conditions for the formation of liberal and neo liberal ideology; determine the place of neoliberal discourse in the ideological landscape of our time; correlate it with other relevant discourses that claim to explain economic, social and cultural processes; to analyze the features of modern practices of developed countries economic domination in relations with the others world countries.Methods. The article, using logical analysis, establishes the main features of modern liberal ideology, allowing us to talk about a new stage in the history of the liberalism development. Comparative analysis allows us to find out the points of liberalism convergence at this stage with other ideological directions in present time. However, statistical analysis reveals important economic factors impeding the reduction of the distance between developed and developing countries.Results. The study showed that to date, the liberal discourse has undergone significant changes, which allows us to talk about a completely new stage in the development of liberal ideology. On the one hand, it was significantly influenced by a general paradigm shift that affected the entire spectrum of socio-economic thought in the 20th century, which we define as an intensifying transition from the Modern paradigm to the Postmodern paradigm. On the other hand, the analysis of the historical path of imperialism and its inherent practices of domination also allows us to talk about its sig nificant transformation in the conditions of the post-industrial economy and the information society. Parallel consideration of these aspects (ideological and practical), the continuous correlation of theory with economic realities allows the authors to define such a complex concept as hyper imperialism. This term is proposed to be used to refer to a specific form of imperialism in a post-industrial manner. At the same time, the intrinsic inseparability of various types of expansion — economic, ideological and, more broadly, civilizational — is taken as its key feature.Conclusion. In the context of a large-scale socio-economic and ideological transformation of a global nature, the need for new forms and means of confronting economic hegemony and finding a path to independent economic and social development is increasing

    Get PDF
    Fluorinated graphene (FG) has been obtained by a fluorination of thermally exfoliated graphite fluoride C2F layers using a gaseous mixture of BrF3 and Br2 at room temperature. Comparative study of electromagnetic (EM) response of thin FG films after recovering their conductivity via different methods is presented in microwave (GHz) and terahertz (THz) frequency ranges. We discovered that fluorination can be used as promising tool for producing tunable EM interference (EMI) shielding materials, combining reflective and absorptive layers

    Three-Dimensional Dynamical Instabilities in Galactic Ionization Fronts

    Ionization front instabilities have long been of interest for their suspected role in a variety of phenomena in the galaxy, from the formation of bright rims and 'elephant trunks' in nebulae to triggered star formation in molecular clouds. Numerical treatments of these instabilities have historically been limited in both dimensionality and input physics, leaving important questions about their true evolution unanswered. We present the first three-dimensional radiation hydrodynamical calculations of both R-type and D-type ionization front instabilities in galactic environments (i.e., solar metallicity gas). Consistent with linear stability analyses of planar D-type fronts, our models exhibit many short-wavelength perturbations growing at early times that later evolve into fewer large-wavelength structures. The simulations demonstrate that both self-consistent radiative transfer and three-dimensional flow introduce significant morphological differences to unstable modes when compared to earlier two-dimensional approximate models. We find that the amplitude of the instabilities in the nonlinear regime is primarily determined by the efficiency of cooling within the shocked neutral shell. Strong radiative cooling leads to long, extended structures with pronounced clumping while weaker cooling leads to saturated modes that devolve into turbulent flows. These results suggest that expanding H II regions may either promote or provide turbulent support against the formation of later generations of stars, with potential consequences for star formation rates in the galaxy today.Comment: 16 pages, 9 figures, accepted to Ap

    The difficulties in translating the attributive group of nouns, known as "nouns chain", – the chain of nouns, in the titles of documents on the material of English-language editions of scientific and technical literature entering the electronic catalog of BEN RAS are discussed. For the first time, the peculiarities of translation of titles are considered under the condition that unions and prepositions are included in the constituent title of the attribute group, as a result of which the "rule of a number" does not work. This situation suggests the emergence of structural and lexical units of a new type, which the authors distinguish as attribute groups with branching nouns. In the practical work of the cataloger it is recommended to use an approach to avoid possible confusion in the translation of these structural and lexical units. In the process of translation it is recommended: to carry out grammatical analysis of the English title, to select the attribute group and to structure it in the proposed template in order to establish logical and semantic links between individual words. A visual representation of the links allows the cataloging translator to see and evaluate the information order of words within the framework of the discussed phenomenon. The recommended analysis makes it possible to identify phrases that meet the known terminological constructions, adequate translation of which contributes to the choice of the correct index of systematization.Обсуждаются трудности, возникающие при переводе атрибутивной группы существительных, известной как «noun chain» – цепочка существительных, в заглавиях документов на материале англоязычных изданий научно-технической литературы, поступающей в электронный каталог БЕН РАН. Впервые рассмотрены особенности перевода заглавий в случае, когда в составляющую заглавие атрибутивную группу входят союзы и предлоги, вследствие чего «правило ряда» не работает. Такая ситуация говорит о появлении структурно-лексических единиц нового типа, которые авторы выделяют как атрибутивные группы с ветвлением существительных. В практической работе каталогизатора рекомендуется использовать подход, позволяющий избежать возможной путаницы при переводе этих структурно-лексических единиц. В процессе перевода рекомендуется: провести грамматический анализ английского заглавия, выделить атрибутивную группу и структурировать её в предложенном шаблоне для установления логических и семантических связей между отдельными словами. Наглядное представление связей позволяет переводчику-каталогизатору увидеть и оценить информационный порядок слов в рамках обсуждаемого явления. Рекомендуемый анализ позволяет выявлять словосочетания, отвечающие известным терминологическим конструкциям, адекватный перевод которых способствует выбору верного индекса систематизации

    Background. Severe fractures of the shin bones are often accompanied by the formation of defects in the tibia, suppuration and soft tissue necrosis. In the case of surgical treatment of fractures, infectious complications reach 3.6-9.1%. One of the methods of treatment of infected defects is resection of the ends of the tibia with shortening. This operation has proven to be effective in the treatment of fresh fractures. The relevance of the work is due to the prospects of using this technique in the treatment of the consequences of fractures with the formation of infected defects of the tibia.Aim of the study. Improving the results of treatment of patients with post-traumatic defects of the tibia complicated by osteomyelitis by performing a shortening resection with simultaneous or sequential correction of the segment length.Material and methods. The results of treatment of 65 patients with diaphyseal post-traumatic tibial defects complicated by osteomyelitis were analysed. They were divided into 2 groups. Group 1 was formed by 31 (47.7%) patients, they underwent shortening resection of the ends of bone fragments in the defect zone with simultaneous lengthening at another level. Group 2 included 34 (52.3%) patients who underwent a shortening resection of the tibia without lengthening. In all cases, the Ilizarov apparatus was used as a fixator.Results. The technique for assessing the size of the true defect of the tibia was optimized taking into account the initial shortening of the segment and the distance between the proximal and distal fragments after resection of their ends. A treatment regimen was developed depending on the level of localization of the tibial defect, and the results of treatment of patients in the compared groups were assessed.Conclusion. Shortening resection is an effective treatment for patients with post-traumatic tibial defects complicated by osteomyelitis. Depending on the level of localization of the defect, it is advisable to carry out treatment according to one of two possible options. When the defect is localized in the upper and middle third of the tibia, shortening resection in an isolated form is shown. If the defect is localized in the lower third of the tibia, it is possible to supplement the shortening resection with an osteotomy in the upper third with Ilizarov lengthening. Актуальность. Тяжелые переломы костей голени нередко сопровождаются образованием дефектов большеберцовой кости, нагноением и формированием некрозов мягких тканей. При оперативном лечении переломов инфекционные осложнения достигают частоты 3,6–9,1%. Одним из методов лечения инфицированных дефектов является резекция концов большеберцовой кости с укорочением с одновременной или последовательной коррекцией длины сегмента. Эта операция доказала свою эффективность при лечении свежих переломов. Актуальность работы обусловлена перспективностью применения данной методики при лечении последствий переломов с образованием инфицированных дефектов большеберцовой кости.Цель работы. Улучшение результатов лечения пациентов с посттравматическими дефектами большеберцовой кости, осложненными остеомиелитом, путем выполнения укорачивающей резекции с одновременной или последовательной коррекцией длины сегмента.Материал и методы. Проанализировали результаты лечения 65 пациентов с диафизарными посттравматическими дефектами большеберцовой кости, осложненными остеомиелитом, которых разделили на две группы. Группу 1 сформировал 31 пациент (47,7%), им выполнили укорачивающую резекцию концов костных фрагментов в зоне дефекта с одновременным удлинением на другом уровне. В группу 2 вошли 34 пациента (52,3%), которым выполнили укорачивающую резекцию большеберцовой кости без удлинения. Во всех случаях в качестве фиксатора использовали аппарат Илизарова.Результаты. Оптимизировали методику оценки величины истинного дефекта большеберцовой кости с учетом исходного укорочения сегмента и расстояния между проксимальным и дистальным фрагментами после резекции их концов. Разработали схему лечения в зависимости от уровня локализации дефекта большеберцовой кости, оценили результаты лечения пациентов в сравниваемых группах.Выводы. Укорачивающая резекция является эффективным методом лечения пациентов с посттравматическими дефектами большеберцовой кости, осложненными остеомиелитом. В зависимости от уровня локализации дефекта целесообразно проводить лечение по одному из двух возможных вариантов. При локализации дефекта в верхней и средней трети большеберцовой кости показана укорачивающая резекция в изолированном виде. При локализации дефекта в нижней трети большеберцовой кости возможно укорачивающую резекцию дополнить остеотомией в верхней трети с удлинением по Илизарову.
