The PBFT (Practical Byzantine Fault Tolerance, PBFT) consensus algorithm, which addressed the issue of malicious nodes sending error messages to disrupt system operation in distributed systems, was challenging support massive network nodes, common participation over all mechanism would lead increased communication complexity, and arbitrary selection master also inefficient consensus. This paper...

accumulation of soft tissue or dentinal remnants in the apical region is a common event that can cause blockage of root canals. this event can be avoided if apical patency is performed during the root canal shaping procedures. however, there is no consensus on the role of apical patency in relation to the success of endodontic treatment of necrotic teeth with apical periodontitis. therefore, th...

Although role theory has long described how expectations shape role behavior, little empirical research has examined differences among work role requirements and how features of the discrete occupational context may influence the extent to which role expectations are shared among role holders. The authors examined consensus in work role requirements from a sample of over 20,000 incumbents acros...

A random rectangular graph (RRG) is a generalization of the random geometric graph (RGG) in which the nodes are embedded into a rectangle with side lengths a and b = 1/a, instead of on a unit square [0, 1]2 . Two nodes are then connected if and only if they are separated at a Euclidean distance smaller than or equal to a certain threshold radius r . When a = 1 the RRG is identical to the RGG. H...
