This paper describes an extension to Kent Retargetable occam Compiler [1] (KRoC), which enables the execution of a blocking call, without blocking the occam-kernel. This allows a process to make a blocking system call (eg, read, write), without blocking processes running in parallel with it. Blocking calls are implemented using Linux clones which communicate using shared memory, and synchronise...

   Two omega-3 fatty acids including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential for the physiologic function of neuronal cell membrane. Normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. Present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine...

Objective(s):Gingivitis is an inflammatory disease that affects tooth-supporting tissues and is caused by a microbe-immune response. The aim of this study was to evaluate the effects of omega-3 fatty acids on immune system regulation and the prevention and treatment of gingivitis using an animal model. Materials and Methods: Gingival inflammation was induced by lipopolysaccharide (LPS) injectio...

Most embedded systems are designed to perform one or fewer specific functions. It is important that the hardware and the software must closely interact to achieve maximum efficiency in all of these realms and overcome the drawbacks found in each aspect. This research focuses on designing a totally new Instruction Set Architecture (ISA) as well as hardware that can closely tie together with the ...

Internet censorship is on the rise as websites around the world are increasingly blocked by government-level firewalls. Although popular anonymizing networks like Tor were originally designed to keep attackers from tracing people’s activities, many people are also using them to evade local censorship. But if the censor simply denies access to the Tor network itself, blocked users can no longer ...

Three main methods of content blocking are used on the Internet: blocking routes to particular IP addresses, blocking specific URLs in a proxy cache or firewall, and providing invalid data for DNS lookups. The mechanisms have different accuracy/cost trade-offs. This paper examines a hybrid, two-stage system that redirects traffic that might need to be blocked to a proxy cache, which then takes ...

We propose a framework for a geometric theory of hybrid systems. Given a deterministic, non-blocking hybrid system, we introduce the notion of its hybrifold with the associated hybrid flow on it. This enables us to study hybrid systems from a global geometric perspective as (generally non-smooth) dynamical systems. This point of view is adopted in studying the Zeno phenomenon. We show that it i...

BACKGROUND Several studies have demonstrated clinical benefits of fish consumption for the cardiovascular system. These effects are attributed to the increased amounts of polyunsaturated fatty acids in these foods. However, the concentrations of fatty acids may vary according to region. OBJECTIVE The goal of this study was to determine the amount of,cholesterol and fatty acids in 10 Brazilian...
