A Generalized Theory of DNA Looping and Cyclization [PDF]
, 2009 We have developed a generalized semi-analytic approach for efficiently computing cyclization and looping $J$ factors of DNA under arbitrary binding constraints. Many biological systems involving DNA-protein interactions impose precise boundary conditions

Modeling of the oxy-combustion calciner in the post-combustion calcium looping process [PDF]
, 2012 The calcium looping process is a fast-developing post-combustion CO2 capture technology in which combustion flue gases are treated in two interconnected fluidized beds. CO2 is absorbed from the flue gases with calcium oxide in the carbonator operating at

Chemical-looping combustion — a thermodynamic study
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2008 The poor performance of internal combustion (IC) engines can be attributed to the departure from equilibrium in the combustion process. This departure is expressed numerically, as the difference between the working fluid's temperature and an ideal ‘combustion temperature’, calculated using a simple expression.

Numerical simulations of fluidization dynamics in a hot model of a CLC process
E3S Web of Conferences, 2017 Chemical Looping Combustion (CLC) is one of the most promising alternatives for solid fuel combustion. CO2 concentration in the exhaust gas is high in CLC technology which enables high efficiency of CO2 capture from flue gas.
