Branching Ratios in Activated Systems
The Journal of Physical Chemistry A, 1997Branching between reaction channels in activated systems is often observed to vary with changes in the potential energy surface as Δln(k1/k2) ∝ Δ(Δ − Δ ). RRKM calculations demonstrate that in many, but not all, cases the log−linear relationship accurately describes branching in nonthermal distributions of reactants with energies well above the ...

Comparison of Pulse Active Ratio Similarity Measurement
2013 1st International Conference on Artificial Intelligence, Modelling and Simulation, 2013Distance measurement is a quantitative tool to measure similarity or dissimilarity between two objects. A correct selection of distance measurement will enhance the performance of a biometric authentication system. In this paper, various types of distance measurement methods such as Euclidean distance, City block distance, Chebyshevdistance ...

Influencing the monophenolase/diphenolase activity ratio in tyrosinase
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2013Tyrosinase is a type 3 copper enzyme with great potential for production of commercially valuable diphenols from monophenols. However, the use of tyrosinase is limited by its further oxidation of diphenols to quinones. We recently determined the structure of the Bacillus megaterium tyrosinase revealing a residue, V218, which we proposed to take part in

Influence of spontaneous activity on peak-ratio analysis
Electroencephalography and Clinical Neurophysiology, 1998To prove or disprove this assumption that in neuropathy patients with abundant spontaneous activity, peak-ratio interference pattern analysis may lead to false negative results.Spontaneous activity >100 microV, automatically analysed by turn/amplitude analysis and expressed as (turns/second)/2 ((T/S)/2), and interference patterns, analysed by the peak ...

Critical Cation Activity Ratios
1972Publisher Summary This chapter (1) recapitulates the problems of measuring the free energies of single ions in the soil that have led to the use of cation activity ratios; (2) explores the conditions that must be met if the rate of uptake or the total uptake of a nutrient or if plant growth is to be regulated, by activity ratios or free energy ...
