This study investigated the phenology, patterns of haul-out habitat use and distribution of the grey seal around Cornwall and the Isles of Scilly. A full census of the coast was carried out by boat over 4 days, in order to make a full count of seals hauled out and close to the coast, and to document all haul-out sites. Regular land-based surveys were made of three haul-out sites in Cornwall, to...

Offspring size affects survival and subsequent reproduction in many organisms. However, studies of offspring size in large mammals are often limited to effects on juveniles because of the difficulty of following individuals to maturity. We used data from a long-term study of individually marked gray seals (Halichoerus grypus; Fabricius, 1791) to test the hypothesis that larger offspring have hi...

During automated driving (SAE Level 3), drivers can delegate control of the vehicle and monitoring road to an system. They may then devote themselves tasks other than gradually lose situational awareness (SA). This could result in difficulty regaining when system requires it. In this simulator study, level SA was manipulated through time spent performing a non-driving task (NDRT), which alterna...

Tor is a well-known anonymous communication system used by millions of users, including journalists and civil rights activists all over the world. The Tor Browser gives non-technical users an easy way to access the Tor Network. However, many government organizations are actively trying to compromise Tor not only in regions with repressive regimes but also in the free world, as the recent FBI in...

Although Tor is the most widely used system for providing anonymity services, its users often experience very high delays. Because much of Tor usage is for Web applications, which are sensitive to latency, it is critical to reduce delays in Tor. To take an important step in this direction, we seek an in-depth understanding of delays in Tor. By taking snapshots of the entire Tor network within a...

Methods Fly stocks All crosses were carried out at 25oC under standard conditions. tor mutants were obtained by crossing tor with tor mutants. tor is the strongest constitutively activated tor mutation. pgc null mutant allele corresponds to the P-element insertion EY7794 (Martinho et al., 2004). pgc and tor double mutants stocks were obtained by recombination with tor or tor mutant alleles, and...

Based on Tor, an anonymous DDoS attack is proposed, and the attacker of this very difficult to trace due strong anonymity Tor. Through conducting experiments in different network environment making analyzation security, results demonstrate effectiveness attack, strategy defense also discussed.
