pseudo-steady state assumption may be used. This condition can be quantified as follow: Let td be the average time it takes for molecule A to travel the diffusion.

The class Math contains methods for performing basic numeric operations such as the elementary exponential, logarithm, square root, and trigonometric functions. Unlike some of the numeric methods of class StrictMath, all implementations of the equivalent functions of class Math are not defined to return the bit-for-bit same results. This relaxation permits better-performing implementations.

The best molecule has won. Whether one should adjust for the time value of money (present value discount), and if so at what rate, is up to each of us. Traditionally, Humira has needed none of that.

For example, Illinois-based Annikki is developing a bioadvantaged molecule – furandicarboxylic acid (FDCA. which is slightly quicker than the average time line. “From the time we first make contact.
