We present a new case of a primary carcinoid tumour of the skin. The mitotic index (4/10 HPF) warrants classification of this case as atypical. The patient was a 58-year-old woman with a 1-year history of a mass on the scalp. Literature review showed this to be only the seventh case of primary carcinoid tumour of the skin. Importantly, the evolution has(More)
We present TRUSS, or Tracking Risk with Ubiquitous Smart Sensing, a novel system that infers and renders safety context on construction sites by fusing data from wearable devices, distributed sensing infrastructure, and video. Wearables stream real-time levels of dangerous gases, dust, noise, light quality, altitude, and motion to base stations that(More)
Wireless sensor networks (WSNs) have potential military, industrial, biomedical, environmental, and residential applications. However, implementing sensor networks and realizing their potential faces various challenges. Sensors nodes should be small in size, ultra-low-power, and WSNs should be comprised of large quantities of sensor nodes [1][2]. These(More)
Landscape conversion by humans may have detrimental effects on animal populations inhabiting managed ecosystems, but human-altered areas may also provide suitable environments for tolerant species. We investigated the spatial ecology of a highly mobile nocturnal avian species-the red-necked nightjar (Caprimulgus ruficollis)-in two contrastingly managed(More)
Landscape change provides a suitable framework for investigating population-level responses to novel ecological pressures. However, relatively little attention has been paid to examine the potential influence of landscape change on the geographic scale of population differentiation. Here, we tested for morphological differentiation of red-necked nightjars(More)
Organic substrates is one of the leading solutions to realize ultra-low-cost and “green” wireless sensor applications. Inkjet printing on paper would be particularly economically appealing if commercial antennas could be replaced with printed antennas with similar performance. This paper presents the replacement of an inkjet-printed, planar, inverted-F(More)
Intra-body electromagnetic propagation through dispersive tissue and studies of wireless power transmission have tended to focus on MHz frequencies due to relatively lower tissue absorption loss in this frequency range. Other studies have focused on the 2.4GHz frequency. The Medical Implant Communication Service, a standard specified by the U.S. Federal(More)
Owing to the lack of an ideal treatment for endometriosis when fertility must be preserved, there are differences of opinion between those in favour of a mainly surgical approach to therapy, those favouring expectant management of the disease's less severe forms and those who prefer an active medical approach. Such controversy has made endometriosis a(More)
