activation threshold
1.The paper introduces the dynamic clonal selection algorithm called DynamiCS in order to extend the N-AIS. The effects of three important system parameters of toleration period, activation threshold and life span are tested and analyzed on artificially created scenarios that reflect two common real circumstances of IDS.
2.The methane molecular beam scattering experiments of La2O3 surface have been made. The adsorption of methane on the clean surface of La2O3 is the translational energy activation adsorption ,its threshold value is 53. 58 kJ/mol. The adsorption of oxygen on the clean surface of La2O3 is suited to the Arrhenius equation ,the desorption peak of oxygen is on 960K.
3.M current is a low threshold, slow-activated, non-inactivating, voltage- and time-dependent potassium current first described in bullfrog sympathetic neurons by Brown and Adam in 1980. Activation of M_1-type muscarinic receptor profoundly inhibits M current, hence it is named "M current", and the channel underlying is called M channel.
