This paper introduces a simple notion of layering as a tool for analyzing well-behaved runs of a given model of distributed computation. Using layering, a model-independent analysis of the consensus problem is performed and then applied to proving lower bounds and impossibility results for consensus in a number of familiar and less familiar models. The proofs are simpler and more direct than ex...

in this paper, the optimal adaptive leader-follower consensus of linear continuous time multi-agent systems is considered. the error dynamics of each player depends on its neighbors’ information. detailed analysis of online optimal leader-follower consensus under known and unknown dynamics is presented. the introduced reinforcement learning-based algorithms learn online the approximate solution...

In a new 340B controversy, OPA rebuffs a court ruling.

Beta2-toxin, encoded by cpb2, is implicated in the pathogenesis of Clostridium perfringens enteritis. However, cpb2 genes from nonporcine C. perfringens isolates were not always expressed, at least in vitro. Nucleotide sequencing identified atypical cpb2 genes with 70.2 to 70.7% DNA identity to previously identified (consensus) cpb2. Atypical beta2-toxin displayed 62.3% identity and 80.4% simil...

The ∆-timed uniform consensus is a stronger variant of the traditional consensus and it satisfies the following additional property: Every correct process terminates its execution within a constant time ∆ (∆-timeliness), and no two processes decide differently (Uniformity). In this paper, we consider the ∆-timed uniform consensus problem in presence of fc crash processes and ft timing-faulty pr...

OBJECTIVES The study aimed to assess usage of inhalation devices in asthma and chronic obstructive pulmonary disease (COPD). METHODS In this two-round Delphi survey, 50 experts in asthma and COPD completed a 13-item, Internet-based, self-administered questionnaire about choice of inhalation device, training and monitoring of inhalation techniques, the interchangeability and the role of costs ...

In the 1980s, a fundamental shift took place in Dutch economic policy: Keynesian demand-management was exchanged for neoliberal supply-side approach. The single most influential account of this transformation has focused on consensus among corporatist policymakers as key to reforms. It is origin story ‘polder model’. problem however, that there surprisingly little evidence 1980s. Instead consen...

We give a simple and intuitive proof of an f + 2 round lower bound for uniform consensus. That is, we show that for every uniform consensus algorithm tolerating t failures, and for every f t − 2, there is an execution with f failures that requires f + 2 rounds.  2002 Elsevier Science B.V.

Research on human reasoning is dominated by demonstrations of the errors people make in various judgment and decision-making tasks. The area of social cognition is not an exception: the list of apparent errors is long and includes a number of contradictory phenomena. Here we explore a prominent example of the contradictory pairs of biases: false consensus and false uniqueness. We show in an emp...
