The IPv4 address space is quickly getting exhausted, putting a tremendous pressure on the adoption of even more NAT levels or IPv6. On the other hand, many authors propose the adoption of new Internet addressing capabilities, namely content-based addressing, to complement the existing IP host-based addressing. In this paper we propose the introduction of a(More)
Otosclerosis (OTSC) is one of the most common causes of hearing loss in white adults. The COL1A1 and COL1A2 genes coding for type-I collagen have been proposed as candidate genes in the development of OTSC. The COL1A1 gene was recently reported to be associated with the condition on the basis of a population-based case-control study. We report here an(More)
A critical component in the design of the Chemical Effects in Biological Systems (CEBS) Knowledgebase is a strategy to capture toxicogenomics study protocols and the toxicity endpoint data (clinical pathology and histopathology). A Study is generally an experiment carried out during a period of time for the purpose of obtaining data, and the Study Design(More)
Wi-Fi hotspots deployed by domestic networks are an attractive approach to foster ubiquitous Internet access for mobile computers. However, it raises several security issues, since the owners of such hotspots cannot be trusted to be honest; therefore, visitors should consider them as potential Man-in-the-Middle attackers. On the other hand, the owners of(More)
IP reconfiguration using DHCP is the usual approach followed by mobile nodes (MNs) when they roam from one network to another one. However, DHCP is too slow for cooping with fast handover requirements. This article describes a cross-layer approach for accelerating DHCP-based IP reconfigurations in a mobility scenario across 802.11 access points (APs). DHCP(More)
Outsourcing of support services (non-core activities) has now become an established trend for many UK organisations, both in the private and public sectors. The public healthcare sector is not excluded from this. Outsourcing, once used as a means to reduce costs, has now acquired strategic significance in organisations. Very little research has been carried(More)
