Lambson (1984) has derived the restrictive conditions under which cooperation may be maintained in a Cournot market with a large numbers of firms. He does this in the context of a repeated game, where a trigger strategy with infinite Nash reversion is the enforcement mechanism. In this paper, Lambson's (1984) result is reinterpreted, and it is argued that cooperation among a large number of Cou...
Effective and simple delivery of DNA vaccines remains a key to successful clinical applications. Previously, we developed novel class vaccines, sometimes called iDNA, which encodes the whole live-attenuated vaccine viruses. Compared standard vaccine, an iDNA required low dose launch in vitro or vivo . The goal this pilot study was investigate if encoding Venezuelan equine encephalitis virus (VE...
In this paper, we present a new method for modeling timeevolving correlation networks, using a Mean Reversion Autoregressive Model, and apply this to stock market data. The work is motivated by the assumption that the price and return of a stock eventually regresses back towards their mean or average. This allows us to model the stock correlation time-series as an autoregressive process with a ...
We estimate a behavioural heterogeneous agents model with boundedly rational traders who know the fundamental stock price, but disagree about the persistence of deviations from the fundamental. Some agents (fundamentalists) believe in mean-reversion of stock prices, while others (chartists) expect a continuation of the trend. Agents gradually switch between the two rules, based upon their relat...
It is unresolved whether recently transmitted human immunodeficiency viruses (HIV) have genetic features that specifically favour their transmissibility. To identify potential "transmission signatures", we compared 20 full-length HIV-1 subtype C genomes from primary infections, with 66 sampled from ethnically and geographically matched individuals with chronic infections. Controlling for recomb...
Quantitative mass conversion of intact bacterial cells of Bacillus subtilis and B. licheniformis to L-phase variants has been effected after lysozyme treatment. After subculture of the unstable L-phase variants for several months in the presence of methicillin, stable L-phase variants were obtained which grew in the absence of the antibiotic and were then unable to revert to the classical bacte...
An experiment is designed to test the implications of the equilibria typically studied in the repeated game literature (i.e. those based on Nash reversion and optimal symmetric two-phase punishment strategies). One hundred pairs of subjects repeatedly set prices in a differentiated demand duopoly setting. Unlike existing experiments there was no fixed end date or time constraint (some pairs pla...
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
