    Global phase diagrams of run-and-tumble dynamics: equidistribution, waves, and blowup

    Full text link
    For spatially one-dimensional run-and-tumble dynamics with mass conservation we develop a coarse phase diagram, that discriminates between global decay to equidistributed constant states, existence of spatially non-trivial waves, and finite time blowup of solutions. Motivated by counter-migrating ripples of high and low population density and fruiting body formation in myxobacteria, we identify phase boundaries as particular critical tumbling dynamics that allow for switching between these spatio-temporal phases upon slight changes in mass densities or parameter values.Comment: 14 pages, 3 figure

    Qualitative Behavior of a Keller-Segel Model with Non-Diffusive Memory

    Get PDF
    In this paper a one-dimensional Keller-Segel model with a logarithmic chemotactic-sensitiviy and a non-diffusing chemical is classified with respect to its long time behavior. The strength of production of the non-diffusive chemical has a strong influence on the qualitative behavior of the system concerning existence of global solutions or Dirac-mass formation. Further, the initial data play a crucial role

    Musical chinoiserie

    Chinoiserie remains relatively unexplored in the context of music and is usually isolated as a mid-eighteenth-century phenomenon characterized by the use of decorative Chinese motifs and concepts in Western art, porcelain, furniture, and architecture. This thesis enriches possible readings of musical chinoiserie by exploring its relationship to the intense fashion for Chinese commodities, its correlation to particular social and political climates, and its connection to the eternal themes of the feminine and utopian pastoral. As a recurring and evolving phenomenon, chinoiserie has been manifested across the past three centuries in various genres and works central to Western music. The following chapters provide case studies which draw attention to particularly rich constellations of ideas about chinoiserie, and analyse the various ways that 'the West' has confronted, represented, and appropriated Chinese difference in music. Chapter two examines the emergence of eighteenth-century European music theatre/ drama inspired by China and its interrelation with royalty and nobility, consumer goods, fashion, and aesthetic sensibility. Chapter three explores early twentieth-century French musical works by Debussy, De Falla, and Roussel, which are inspired by nostalgic and utopian Chinese landscapes. In chapter four, the music of Mahler, Puccini, and Stravinsky reveal alternative fin de siĂšcle approaches to chinoiserie. Common themes include an increased interest in authenticity; overt and subsumed Chinese elements; and the integration of chinoiserie into existing programmes. As a counterpoint to this, chapter five turns to popular music genres which directly responded to the social and political reality of Chinese immigration to America. The straightforward, formulaic, and market driven style of Tin Pan Alley songs provides the most explicit examples of musical chinoiserie, which upon examination reveal a variety of hidden beliefs, prejudices, aspirations and idealized visions of China. By no means are these chapters intended to offer a comprehensive survey of musical chinoiserie, but they provide case studies which demonstrate the ways in which a musical work can interact with a multiplicity of intellectual and emotional responses to the West's encounter with China during important social, political, and historical events

    Enhanced heart rate prediction model using damped least-squares algorithm

    Monitoring a patient’s vital signs is considered one of the most challenging problems in telehealth systems, especially when patients reside in remote locations. Companies now use IoT devices such as wearable devices to participate in telehealth systems. However, the steady adoption of wearables can result in a significant increase in the volume of data being collected and transmitted. As these devices run on limited battery power, they can run out of power quickly due to the high processing requirements of the device for data collection and transmission. Given the importance of medical data, it is imperative that all transmitted data adhere to strict integrity and availability requirements. Reducing the volume of healthcare data and the frequency of transmission can improve a device’s battery life via an inference algorithm. Furthermore, this approach creates issues for improving transmission metrics related to accuracy and efficiency, which are traded-off against each other, with increasing accuracy reducing efficiency. This paper demonstrates that machine learning (ML) can be used to overcome the trade-off problem. The damped least-squares algorithm (DLSA) is used to enhance both metrics by taking fewer samples for transmission whilst maintaining accuracy. The algorithm is tested with a standard heart rate dataset to compare the metrics. The results showed that the DLSA provides the best performance, with an efficiency of 3.33 times for reduced sample data size and an accuracy of 95.6 %, with similar accuracies observed in seven different sampling cases adopted for testing that demonstrate improved efficiency. This proposed method significantly improve both metrics using ML without sacrificing one metric over the other compared to existing methods with high efficiency

    The Criteria to Identify Pornography That Can Support Healthy Sexual Development for Young Adults: Results of an International Delphi Panel

    Get PDF
    Pornography is not homogenous. There is a paucity of research that offers guidance to young adults and adult stakeholders interested in navigating the available range of pornography to find materials that support healthy sexual development for young adults. Drawing on the expertise of a Delphi Panel of experts from a range of relevant areas this article offers six criteria for assessing whether pornography can support healthy sexual development: includes a variety of sexual practices; includes a variety of body types, genders and races; shows negotiation of consent on screen; is known to be ethically produced; focuses on pleasure for all participants; shows safe sex. The article identifies four pornographic websites that meet these criteria: Sex School, Make Love Not Porn, PinkLabel.TV and Lust Cinema
