Cross Recurrence Plot Based Synchronization of Time Series

The method of recurrence plots is extended to the cross recurrence plots (CRP), which among others enables the study of synchronization or time differences in two time series. This is emphasized in a distorted main diagonal in the cross recurrence plot, the line of synchronization (LOS). A non-parametrical fit of this LOS can be used to rescale the time axis of the two data series (whereby one of it is e.g. compressed or stretched) so that they are synchronized. An application of this method to geophysical sediment core data illustrates its suitability for real data. The rock magnetic data of two different sediment cores from the Makarov Basin can be adjusted to each other by using this method, so that they are comparable.Comment: Nonlinear Processes in Geophysics, 9, 2002, in pres

The Revolutionary Public Sphere: The Case of the Arab Uprisings

A comprehensive picture of dissent in the Arab uprisings requires an understanding of how revolutionaries have represented themselves and how various media, digital and otherwise, were incorporated in these communicative processes. Together, the articles in this Special Issue focus on the myths, ideologies, and histories that inspired slogans, murals, and poems of pointed social relevance and politically potency. Originally presented at the inaugural biennial symposium of what was then the Project for Advanced Research in Global Communication in 2014, these papers explore the creative permutations of symbols, words, images, colors, shapes, and sounds that revolutionaries deployed to contest despots, to outwit each other, to attract attention, and to conjure up new social and political imaginaries. The issue exemplifies one of the fundamental principles undergirding the institutional mission of the Center for Advanced Research in Global Communication: a robust dialogue between theoretical advances on one hand, and deep linguistic, cultural, historical knowledge of the world region under study, on the other.

Mediating Islamic State: Introduction

How does the group that calls itself “Islamic State” communicate? How has Islamic State been understood and contested? This Special Section gathers emergent scholarly voices, many deploying humanistic inquiry, to probe a phenomenon that has predominantly been the province of social scientists, to explore and understand the players, patterns, and practices that have mediated Islamic State: the communicative ways in which the group has been studied, reported on, visualized, narrated, mocked, spoofed, and resisted. We use “mediation” rather than “media” to shift public discourse on Islamic State beyond the focus on technology that has characterized research on media and sociopolitical change generally, and Islamic State communication in particular. We seek to understand the historical, ideological, technological, and cultural complexity of Islamic State, meshing translocal struggles with global geopolitics. Mediation connotes a broad approach to media, which includes words, images, bodies, platforms, and the expressive capacities and meaning-making practices that communicators generate when they deploy these media

Power-laws in recurrence networks from dynamical systems

Recurrence networks are a novel tool of nonlinear time series analysis allowing the characterisation of higher-order geometric properties of complex dynamical systems based on recurrences in phase space, which are a fundamental concept in classical mechanics. In this Letter, we demonstrate that recurrence networks obtained from various deterministic model systems as well as experimental data naturally display power-law degree distributions with scaling exponents $\gamma$ that can be derived exclusively from the systems' invariant densities. For one-dimensional maps, we show analytically that $\gamma$ is not related to the fractal dimension. For continuous systems, we find two distinct types of behaviour: power-laws with an exponent $\gamma$ depending on a suitable notion of local dimension, and such with fixed $\gamma=1$.Comment: 6 pages, 7 figure

CEDNIK: Phenotypic and molecular characterization of an additional patient and review of the literature

Synaptosomal-associated protein 29 (SNAP29) is a t-SNARE protein that is implicated in intracellular vesicle fusion. Mutations in the SNAP29 gene have been associated with cerebral dysgenesis, neuropathy, ichthyosis, and keratoderma syndrome (CEDNIK). In patients with 22q11.2 deletion syndrome, mutations in SNAP29 on the nondeleted chromosome are linked to similar ichthyotic and neurological phenotypes. Here, the authors report a patient with cerebral dysgenesis, neuropathy, ichthyosis, and keratoderma syndrome who presented with global developmental delay, polymicrogyria, dysgenesis of the corpus callosum, optic nerve dysplasia, gaze apraxia, and dysmorphic features. He has developed ichthyosis and palmoplantar keratoderma as he has grown. Exome sequencing identified a homozygous nonsense mutation in SNAP29 gene designated as c.85C>T (p.Arg29X). The authors compare the findings in the proband with previously reported cases. The previously unreported mutation in this patient and his phenotype add to the characterization of cerebral dysgenesis, neuropathy, ichthyosis, and keratoderma syndrome and the accumulating scientific evidence that implicates synaptic protein dysfunction in various neuroectodermal conditions

Guidelines for Sustainable Construction Methods to Build Over Difficult Topographies

Sustainable construction development is a recent term that is required to create an eco-friendly built environment using renewable and recyclable resources and to reduce energy consumption and waste within protecting the natural environment. This term means such an improvement that pleases the current requirements without limitation of the prospect of sustaining requirements in future. Many problems face builders while executing projects, especially these projects were decided to be built over difficult topographies, such as rivers, falls, inclinations, caves, ridges, cliffs, and mountains. Construction challenges to build a project over a difficult topography are diverse starting by executing piles, retaining walls, conserving stability, and choosing the proper sustainable materials that can withstand the natural environmental factors. This paper sheds the light on the potential of any site\u27s certain criteria; mostly its topography and slope on the provision of sustainable and ecological buildings. It seeks to recognize the sustainable and ecological variables of site topography, consuming a set of characteristics for each building type. The main aim of this research is to propose guidelines of sustainable construction methods that can be used to enable builders to build over difficult topographies, particularly on mountains. The research therefore depended on a scientific methodology through analyzing a sort of literature sources to structure a theoretical base, and then certain parameters were concluded. These parameters were used to analyze a concentrated case study on a site attaching (Beaufort Castle-Chkif), located in Arnoun South of Lebanon. Data of this field-work was conducted by site-visits, capturing photos, interviews, and questionnaire. This site is envisioned to be tested for building projects over sloped contour lines of Chkif Mountain. The paper provides an application for the development of the guidelines for passive and sustainable capability on favorite orientations on the buildings in difficult sloped areas with respect to the climatic local data, Application of the idea of the sustainable and ecological development in the building construction will be an origin of engineering and scientific inspiration for many coming years. One of the conclusion points is the preferable typology of projects to be built over mountains is touristic and entertainment activity to attract people. The sloped contour lines may be employed to be a potential not threat

Extended Recurrence Plot Analysis and its Application to ERP Data

We present new measures of complexity and their application to event related potential data. The new measures base on structures of recurrence plots and makes the identification of chaos-chaos transitions possible. The application of these measures to data from single-trials of the Oddball experiment can identify laminar states therein. This offers a new way of analyzing event-related activity on a single-trial basis.Comment: 21 pages, 8 figures; article for the workshop ''Analyzing and Modelling Event-Related Brain Potentials: Cognitive and Neural Approaches`` at November 29 - December 01, 2001 in Potsdam, German

Pin-fin shape and orientation effects on wall heat transfer predictions of gas turbine blade

Turbine blades are often exposed to the ‘hot’ gas environment and thus it is essential to apply effective cooling technique to extend the blade lifetime. In the present work, wall heat transfer characteristics inside a blade trailing-edge coolant passage were investigated by analyzing two baseline configurations experimentally studied by previous researchers. In addition, three new configurations were proposed by varying shape and orientation against an incoming airflow. All these five configurations adopted similar layout with five-row elliptic pin-fins in the main coolant region and one-row fillet circular pin-fin in the exit region. Validation study was started by two baseline configurations by comparing CFD predictions with experimental measurements, followed by wall heat transfer predictions of three newly proposed configurations. It was found that pin-fin shape and its orientation have considerable effects on the wall heat transfer characteristics, and that by rotating the pin-fin against incoming flow, some compromises could be achieved, such as higher heat transfer coefficient and lower pressure loss
