The Logarithmic Number System (LNS) can be considered a simplification of the Floating Point (FP) Number System that assumes the mantissa is always equal to one, and has a binary fixed-pointâ€¦ (More)

Drug synthesis and discovery represents today one of the most rapidly evolving scientific areas. This is primarily due to the interdisciplinary collaboration between chemists, pharmacologists,â€¦ (More)
