  1. Smooth-supported multiplicative functions in arithmetic progressions beyond the $x^{1/2}$-barrier

    Drappeau, S; Granville, A; Shao, X
    We show that smooth-supported multiplicative functions $f$ are well-distributed in arithmetic progressions $a_1a_2^{-1} \pmod q$ on average over moduli $q\leq x^{3/5-\varepsilon}$ with $(q,a_1a_2)=1$.

  2. Endovenous laser ablation therapy in children: applications and outcomes.

    Patel, PA; Barnacle, AM; Stuart, S; Amaral, JG; John, PR
    BACKGROUND: Endovenous laser ablation is well recognized as the first-line treatment for superficial venous reflux with varicose veins in adults. It is not widely reported and is not an established practice in pediatric patients. OBJECTIVE: To illustrate a variety of pediatric venous conditions in which endovenous laser ablation can be utilized and to demonstrate its feasibility and safety in children. MATERIALS AND METHODS: We conducted a retrospective review of endovenous laser ablation procedures performed between January 2007 and July 2014 at two large pediatric institutions. RESULTS: We included 35 patients (17 males) who underwent endovenous laser ablation to 43 veins....

  3. Comparison of Maximum Likelihood and GAN-based training of Real NVPs

    Danihelka, I; Lakshminarayanan, B; Uria, B; Wierstra, D; Dayan, P
    We train a generator by maximum likelihood and we also train the same generator architecture by Wasserstein GAN. We then compare the generated samples, exact log-probability densities and approximate Wasserstein distances. We show that an independent critic trained to approximate Wasserstein distance between the validation set and the generator distribution helps detect overfitting. Finally, we use ideas from the one-shot learning literature to develop a novel fast learning critic.

  10. Corticosteroids and hip fracture risk in elderly respiratory patients: EPIC-Greece cohort.

    Karakatsani, A; Katsoulis, M; Klinaki, E; Trichopoulou, A
    INTRODUCTION: In an ageing population the prevalence of osteoporosis and chronic respiratory diseases is expected to increase in the near future. Interestingly, several forms of corticosteroids, drugs implicated in osteoporosis pathogenesis, are prescribed to respiratory patients without taking into consideration their age and risk for osteoporotic fractures. The aim of this study was to investigate the risk for hip fracture of the elder individuals who are taking corticosteroids for respiratory disease, including inhalers. MATERIAL AND METHODS: Data on incident hip fractures were collected through the active follow-up for all individuals participating in the Greek segment of the European Prospective Investigation...

  11. The effect of smoking on bone healing: A systematic review.

    Patel, RA; Wilson, RF; Patel, PA; Palmer, RM
    OBJECTIVES: To review the systemic impact of smoking on bone healing as evidenced within the orthopaedic literature. METHODS: A protocol was established and studies were sourced from five electronic databases. Screening, data abstraction and quality assessment was conducted by two review authors. Prospective and retrospective clinical studies were included. The primary outcome measures were based on clinical and/or radiological indicators of bone healing. This review specifically focused on non-spinal orthopaedic studies. RESULTS: Nine tibia studies and eight other orthopaedic studies were considered for systematic review. Of these 17 studies, 13 concluded that smoking negatively influenced bone healing. CONCLUSIONS: Smoking has...

  12. Sudden cardiac death in inherited cardiomyopathy.

    Collis, R; Elliott, PM
    Cardiomyopathy is an important cause of sudden cardiac death particularly in adolescents and young adults. The risk of sudden cardiac death varies between individual cardiomyopathies and is dependent on the severity of disease, age and gender. Although rare in cardiomyopathies, a fundamental aspect of clinical management is a systematic and thorough clinical assessment to identify the small number of individuals who are at risk and who can be protected with prophylactic ICD therapy.

  17. Visual Deception and the Beholder in Cinematic Space: the role of imaginative perception in film viewing

    Cammack, J
    This thesis investigates the experience of viewing unstable moving-images and proposes a provisional framework for how they are perceived. The term ‘unstable’ is used to indicate cinematic images whose representational content is not immediately recognized, and which do not readily resolve into a single, reliable interpretation. The perception of ambiguous images is investigated within the broader context of cognitive film theory, and from the distinct and often contrasting viewpoints of neuroscience and phenomenology. Framed by the Direct and Constructivist models of perception, the research draws on aspects of both approaches to analyse the phenomenal experience of the film viewer in...

  18. Cross-national comparison of internal migration: Issues and measures

    Bell, M; Blake, M; Boyle, P; Duke-Williams, O; Rees, P; Stillwell, J; Hugo, G
    Our objectives are to identify the issues that researchers encounter when measuring internal migration in different countries and to propose key indicators that analysts can use to compare internal migration at the 'national' level. We establish the benefits to be gained by a rigorous approach to cross-national comparisons of internal migration and discuss issues that affect such comparisons. We then distinguish four dimensions of internal migration on which countries can be compared and, for each dimension, identify a series of summary measures. We illustrate the issues and measures proposed by comparing migration in Australia and Great Britain.

  19. Anticipation mobile digital health: Towards personalized proactive therapies and prevention strategies

    Pejovic, V; Mehrotra, A; Musolesi, M
    © Springer International Publishing Switzerland 2017.Recent advances in healthcare illuminated the role that individual traits and behaviors play in a person’s health. Consequently, a need has arisen for, currently expensive and non-scalable, continuous long-term patient monitoring and individually tailored therapies. Equipped with an array of sensors, high-performance computing power, and carried by their owners at all times, mobile computing devices promise to enable continuous patient monitoring, and, with the help of machine learning, build predictive models of patient’s health and behavior. Moreover, through their close integration with a user’s lifestyle, mobiles can be used to deliver personalized proactive therapies. In...
