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)
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Abstract— 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.(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 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)
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)
1. This work examines the effects of fenoterol on the isolated skin of the Chilean toad Pleurodema thaul. 2. A dose-dependent increase in the potential difference and in the short-circuit current of the skin was found. Furthermore, sodium potential (ENa) and sodium conductance (GNA) also rose. 3. The increase in bioelectric parameters was reversibly blocked(More)
Almost all the earthquakes included in the catalog for the Iberian±Maghrebian area up to 2000 have been used in order to know the structure of the Alboran Sea area after the veri®cation of the aleatory nature of the errors in their spatial localization. A new focal mechanisms catalog has also been used as well as many of the available geological data.(More)
