Hidden Markov models are used to describe the "stepping" behavior of molecular motors, as measured by single-molecule fluorescence techniques. Our HMM implementation is more versatile than the one described by Milescu, et al. Biophys. J. 91:3135-3150 and can be used as a "blind" step detector or...

We solve a binary distillation problem using the solution of a Riccati equation. We find that four plates are needed to achieve the desired product purity. We also compute the number of stages with the classical approach by stepping off stages using the equilibrium curve and the operating line....

The code is written to find one mixed Nash equilibrium strategy apart from all pure Nash equilibria in a bimatrix or general sum two person matrix game. It is based upon the algorithm presented by O.L. Mangasarian in 1964. It uses quadprog to solve a quadratic programming problem for a two person...

We use the SRK equation of state to compute the correction factor due to gas-phase nonideality as a result of the high pressure applied in the ammonia synthesis. We also compute the extent of reaction. Plots of these two quantities versus pressure for temperature equal to 800K are presented. The...

Gas absorption is a very ubiquitous unit operation in any chemical plant. It has in common with liquid-liquid extraction that there are two carrier streams and one solute to be partioned between them. Here, we use the McCabe and Thiele graphical method to study the separation of acetone from air....

The Hardy Weinberg equilibrium is a fundamental law in genetic.This function was deeply rewrited.If a locus is biallelic the function use the exact Hardy Weinberg test (similar to Fisher exact test) analyzing all possible tables. If you download TERNPLOT functions (ID:2299) the function plots a...

The program shows how to plot figure 14.4 page 248 presented in T. L. Hill, An Introduction to Statistical Thermodynamics, Dover, New York, 1986. The Bragg-Williams approximation gives pressure-volume isotherms similar to those obtained using the van der Waals equation and it predicts first-order...
