What is the evolutionary advantage of having one's brain left hemisphere control the right side of the body & right hemisph. control the left side?

What is the reason for the two brain hemisoheres to control the sides of the body opposite to them? Is this phenomenon also true for lower mammals such as mice, rats and squirrels, for example?

Has anybody applied Fourier transformation on stock market graphs?

If it can be resolved into simple sinusoids, it might be possible to predict stock market behavior, even if only with partial success. But I am sure that there is a straight line component with a...

Can someone recommend a good and clearly-written textbook on "Digital Signal Processing"?

I have no formal training in electrical engineering (where DSP is staple) but I do have a bachelor's degree in mathematics. I prefer a textbook with plenty of examples. Thanks very much in advance!

Are there any good and well-written books or treatises on 'Signal Detection Theory' and 'Theory of Maximizing Signal-to-Noise Ratio' ?

I believe (as do many others) that these two topics are crucial to unraveling key information from data mining results, especially biological DM. However, my observation is that these 2 key...

Is there any electromagnetic radiation with higher energy than gamma rays and lower energy than ELF?

I was wondering if the upper and lower limits of the electromagnetic spectrum have been extended through modern research. Gamma rays, with energies of 1.24 MeV, constitute the upper limit, and ELF...
