Lateral saccadic latencies were determined in 18 right-handers and 18 left-handers. Within the right-handed group the mean latency was significantly shorter when looking from the left to the right (242.7 msec) than from right to left (265.0 msec), whereas no significant directional difference was found in the left-handed group. An age effect was also found(More)
This experiment determined whether reaction to a novel stimulus was diminished in a dose-dependent fashion following 8 consecutive days of d-amphetamine administration. Thirty-two male rats were injected with saline, 0.5, 2.5, or 5.0 mg/kg of d-amphetamine (each N = 8). On the ninth day, all animals received saline injections and were tested (a) in the(More)
The deployment of IPv6 enabled devices and networks brings some issues, which must be addressed by security administrators in order to guarantee at least the same level of security obtained nowadays with IPv4 and network-based security schemes, allowing at the same time all the IPv6 advantages and possibilities. The most important issues are the rediscovery(More)
This paper aims to describe the main outputs of the work carried out inside the IST Euro6IX project with particular reference to a new possible architectural Internet Exchange model. This model is based on the IPv6 hierarchical and aggregatable routing and addressing model permitting to enhance the IX functionalities by proposing to directly assign(More)
This paper presents the "auto-transition" concept which tries to ensure that any network device can obtain IPv6 connectivity at any time and whatever network is attached to, even if such network is connected to Internet only with IPv4. The algorithm looks for the best possible transition mechanism according to performance criteria as well as the scenario(More)
The S-100 protein was measured in 7 discrete brain areas from rats raised in an enriched, social, or isolated environment for 21, 42, or 84 days after weaning. S-100 was measured at significantly higher concentrations under enriched than under social environmental conditions in cerebellum and brainstem at 21 days but not thereafter. The protein in(More)
SUMMARY Tunneling is commonly used in several transition mechanisms. Some of the mechanisms discover the tunnel endpoint automatically by their own means. This paper describes several tunnel discovery mechanisms for IPv6 traversal beyond IPv4 legacy networks and suggests a new mechanism by which the DHCPv4 server can automatically provide configuration(More)
The actual trends on telecommunications and electronics in general are the convergence to all-IP networks and protocols. Consequently, new devices are appearing requiring more and more IP addresses. This is the situation present around the home/industrial automation and in general remote monitoring. Nowadays more homes and buildings are entering into the(More)
The deployment of IPv6 has been a very slow process. However in the last months, very important signs of the progress are appearing, demonstrating that is no longer an utopia, but a fact, which just follows a natural process, equivalent to the take-off of any other new technology. One of the main issues has been the "chicken and egg" paradigm. The lack of(More)
