The RcsCDB phosphorelay system controls an extremely large regulon in Enterobacteriaceae that involves processes such as biofilm formation, flagella production, synthesis of extracellular capsules and cell division. Therefore, fine-tuning of this system is essential for virulence in pathogenic microorganisms of this group. The final master effector of the RcsCDB system is the response regulator...

Scalability is a fundamental problem for information systems when the amount of managed data increases. Peer to Peer systems are usually used to solve scalability problems as centralized approaches do not scale without large dedicated infrastructure. But most current Peer to Peer systems do not take into account that indexed data can be dynamic and change their values very often. Thus, we propo...

The traditional view that proteins possess absolute functional specificity and a single, fixed structure conflicts with their marked ability to adapt and evolve new functions and structures. We consider an alternative, "avant-garde view" in which proteins are conformationally dynamic and exhibit functional promiscuity. We surmise that these properties are the foundation stones of protein evolva...

Information systems (IS) building, as described in the literature, consist of two main phases: IS strategic planning and IS development. The IS strategic planning phase is performed every few years and produces a long-term strategic plan. The IS development phase is performed annually by IS management and produces a development plan for the next year and outlines development activities. The act...

Studies of human decision making have demonstrated that stress exacerbates risk taking. Since all decisions involve some element of risk, stress has critical impact on decision quality. Decisions are found to improve with stress up to an optimal threshold beyond which deterioration is observed. However, few studies have examined the psychological experiences underlying risk-taking behavior in c...
