Open Shortest Path First (OSPF) is a popular link state routing protocol widely used in Internet infrastructure. OSPF implements several timers to limit the protocol overhead. With these timers, it usually takes several tens of seconds for OSPF network to recover from a failure. The convergence time is delayed mainly by the timers of failure detection and routing calculation scheduling. In this...

This conceptual paper addresses the question of how the competencies of old timers are transferred to newcomers in the context of a technology company. First, an individual’s personal competence is analysed and further illustrated by focusing on how it alters in the course of his or her working life. Second, competence transferring process is analysed by the tool ‘Holistic Concept of Man’. Thir...

A feature of current membrane systems is the fact that objects and membranes are persistent. However, this is not true in the real world. In fact, cells and intracellular proteins have a well-defined lifetime. Inspired from these biological facts, we define a model of systems of mobile membranes in which each membrane and each object has a timer representing their lifetime. We show that systems...

Silver(I) complexes with aromatic donors are thoroughly analyzed (with aid of the Cambridge Crystallographic Database) to identify the basic structural factors inherent to the bonding of an arene ligand. Most strikingly, the distance parameter d (which simply measures the normal separation of Ag from the mean aromatic plane) is singularly invariant at d = 2.41 +/- 0.05 A for all silver/arene co...

Neutrophils are able to release cytotoxic substances and inflammatory mediators, which, along with their delayed apoptosis, have a potential to maintain permanent inflammation. Therefore, treatment of diseases associated with chronic inflammation should be focused on neutrophils; formation of reactive oxygen species and apoptosis of these cells represent two promising targets for pharmacologica...

Several projects have tried to rework Linux time and timers code to add functions such as high-precision timers and dynamic ticks. Previous efforts have not been generally accepted, in part, because they considered only a subset of the related problems requiring an integrated solution. These efforts also suffered significant architecture dependence creating complexity and maintenance costs. Thi...
