During the last decade, several studies have argued that sticky information model proposed by Mankiw and Reis (2002), in which firms update their information occasionally rather than instantaneously, explains some stylized facts about the inflation dynamics. Sticky information pricing model successfully captures the sluggish movement of aggregate prices in response to monetary policy shocks. De...

It is proved in a quite general Feynman diagram model that the presence of diffractively produced inelastic channels at high energies leads to a decrease in the total cross section below as well as above the threshold for the process. A nondiffractive channel is shown to lead to the opposite effect, namely, the total cross section is increased at large energies. Asymptotically, the former behav...

We describe calculations of cc production to next-to-next-to-leading order (NNLO) and next-to-next-to-leading logarithm (NNLL) near threshold in pp and πp interactions. We study the relevance of these calculations for existing cc total cross section data by examining their sensitivity to partonic threshold kinematics, their convergence properties and scale dependence.

Turbocharged CNG engines produce high NOx emission due to the fuel type and high combustion temperature. In this research, the effects of lean-burn and waste gate opening pressure threshold on NOx emission are studied theoretically and experimentally at WOT condition as well as 13-mode ECE-R49 test cycle. A code is developed in MATLAB environment for predicting engine NOx and the results are va...
