This paper considers a model of economic network characterized by an endogenous architecture and frictions in the relations among agents as described in Bala and Goyal (2000). We propose a similar network model with the difference that frictions in the relations among agents are endogenous. Frictions are modeled as dependent on the result of a coordination game, played by every pair of directly...

This paper considers a stylized model of network formation in which relations among agents are subject to frictions, as described in Bala and Goyal [A non cooperative model of network formation, Econometrica 68 (2000) 1181–1231]. We analyze the process of network formation in a dynamic framework where selfinterested individuals can form or delete links and, occasionally, make mistakes. Then, us...

Structural transitions and the melting behavior of crystalline poly(ethylene oxide), (CH2-CH2-O)n, (PEO) has been investigated using fully atomistic, constant pressure-constant temperature (NPT) molecular dynamics (MD) simulations. Melting of PEO proceeds in two stages; Order parameters reveal the loss of interchain orientational correlations and of chain helicity in the first and second stages...

Seasame oil is the most stable vegetable oil against oxidation. It has been revealed that the oxidative stability of seasame oil is due to the lignans such as sesamole, sesamilinol, pynoresional, sesaminol, etc., contained in it. Sesamol is obtained by the hydroxylation of sesamolin. The reaction is hydroxylation which is generally promoted by acid and heat. The changes of the concentration of ...
