    Collaboration and interconnectivity: Nottinghamshire Fire and Rescue Services and higher education institutions in Nottingham

    No full text
    This paper will describe the developing relationship between Nottinghamshire Fire and Rescue Services and the two Higher Education Institutions in Nottingham. It will chronicle how a very traditional relationship has been transformed, initially by a simple consultancy project, into a much closer working relationship characterised by a much richer variety of collaborative projects. It demonstrates the potential mutual benefits that greater trust and reciprocity between the institutions can bring to both academia and to practice and the impact it has already had on curriculum development, teaching and learning in Nottingham

    OBJECTIVE: Purpose of this retrospective study was (1) to evaluate overall survival and survival to local recurrence of patients with unifocal and multifocal tumor and (2) to evaluate survival to local recurrence after intralesional or wide surgery. MATERIAL AND METHODS: We reviewed 62 patients with epithelioid hemangioendothelioma of bone, treated from 1985 to 2010. Histological sections and immunohistochemistry were evaluated. Tumor presented as unifocal in 49 patients and as multifocal in 13. RESULTS: Mean follow-up was 9 years. Five patients (10%) with unifocal tumor progressed to multifocal. Overall survival was 92% at 10 years. Survival with unifocal tumor was significantly higher than survival with multifocal tumor. Survival to local recurrence was 76% at 10 years, significantly higher after wide resection than after intralesional surgery, while there was no statistical difference comparing unifocal and multifocal tumor. At multivariate analysis both variables showed no statistically significance. CONCLUSION: Wide surgical excision reduces the risk of local recurrence, but functional results and morbidity need to be considered individually when defining surgical indications. Due to the risk of radiation-induced sarcomas, radiation therapy should be reserved to those cases not amenable to wide surgery or when lesions are seated locations difficult to treat. J. Surg.

    p-CARMA: Politely Scaling LoRaWAN

    No full text
    Long Range Wide Area Network (LoRaWAN) covers the needs of energy-constrained IoT-devices for operational longevity and extended communication range in a best-effort fashion. However, Lo- RaWAN’s minimalist design cannot handle the traffic from dense deployments with more than a few hundred devices connected to a single gateway, since each LoRa-device transmits data-packets without any information regarding the availability of the medium. In this paper, we try to improve the scalability of LoRaWAN by manifolds, serving thousands of devices per gateway. We present a novel protocol called p persistent-Channel Activity Recognition Multiple Access (p-CARMA) that exploits LoRaWAN’s Channel Activity Detection (CAD) as a crude mechanism to assess if the channel is free. Due to CAD’s imperfections (it only scans for preambles, not for any channel activity) p-CARMA operates probabilistically with each device deciding on a p value based upon local estimation. At the beginning of operation, this estimate is derived from pure local information, that is without involvement of the gateway, and devices automatically adapt to changes in the environment. Then, the adaptation of p-value is assisted by critical information on the cumulative device-delays, multicasted by the gateway at regular, large timespans. To evaluate the performance of p-CARMA, we implemented it in ns-3 based upon a detailed characterization of LoRaWAN’s CAD mechanism involving an extensive set of real-world experiments. We compared p-CARMA to vanilla LoRaWAN as well as a variant using the theoretically optimal p = 1=N (N being the total number of devices). The simulation results show that p-CARMA achieves from three-fold, up to a twenty-fold higher Packet Reception Ratio than LoRaWAN while handling thousands of devices. Further, its adaptivity outperforms the fixed p-value by a factor of 5.25 when scaling up. Moreover, p-CARMA does so while consuming 37.31%-58.17% less energy on average per device compared to vanilla LoRaWAN.Embedded SystemsElectrical Engineering, Mathematics and Computer Scienc
