Butterfly effect

Butterfly effect

That the flap of a butterfly’s wing might lead to a storm or other event halfway around the globe is a popular image used to introduce chaos theory. But two small lepidopterans appear to have played a major part in the scrapping of plans to build a new nuclear power station on a shingle bank in the south-east of England, which is becoming an increasing focus in the International Year of Biodive...

Butterfly Effect Fractal

In this paper, a new concept of integration of fractal and the butterfly effect is proposed and implemented. A new fractal program was designed and developed to perform such integration. Among many existing fractal and chaos software programs, none of them allow us to achieve the resulting patterns demonstrated in this paper. Moreover, it is the first time that a fractal program provides functi...

The Security Butterfly Effect

MicroRNAs and the butterfly effect

MicroRNAs are nature’s dimmer switches for protein translation. When expressed in sufficient abundance, these singlestranded small RNAs bind to complementary nucleotide sequences in the 3' untranslated regions of target mRNAs and direct them to RNA-induced silencing complexes (RISCs) for translational suppression and degradation. Although much has been learned about the molecular mechanisms of ...

Portfolio Optimization, Heuristics, and the "Butterfly Effect"

The same effect is at work with portfolio optimizers that perform asset allocation and portfolio allocation chores. A small change to an input works its way through the system of equations and results in a large change in allocations. As a result, it is very easy to arrive at a set of "non-intuitive" allocations; i.e. they don't exhibit common sense. Once a set of portfolio allocations is put i...
