A method and apparatus, especially suited for computers that can execute fused multiply-add instructions, for performing a fast Fourier transform (FFT) are disclosed. Divisions by zero that create a risk of error in other methods are avoided. In a first example embodiment, a zero divisor is detected and the division circumvented by performing an alternate computation. In a second example embodiment, a zero divisor is detected replaced by a safe finite value. In a third example embodiment, two optimized FFT kernels are used, one avoiding division by a zero real part of a root of unity and one avoiding division by a zero imaginary part. In a fourth example embodiment, a first kernel computes some kernel iterations without multiplication, and a second, optimized kernel computes the remaining iterations without risk of division by zero.

To prevent intimal hyperplasia within a dialysis graft, a flexible tube comprising the dialysis graft is coated interiorly before placement with an anticarcinogen or mitosis-inhibiting agent for preventing cell division. The graft can also be irradiated with light energy by directing light into the lumen of the tube that has been grafted in place, thereby preventing or reducing dialysis graft intimal hyperplasia and reducing inflammation. The light source can be a light emitting diode (LED) or a chemical light source, i.e., a chemiluminescent substance for producing cool light energy within the graft to prevent or reduce the symptoms of GIH. When phototherapy is used, the body is exposed to light radiation at the site of the graft in sufficient amount to prevent undesired cell proliferation within the vessels, the graft, or surrounding tissue where the invention is used without detectable damage to body tissue. For various applications, visible light can be used, e.g., visible blue or red light or the combination is employed. Blue and red light can be produced by an incandescent lamp or other suitable lamp, an LED, a laser or chemical light source with wavelengths predominantly between about 300 nm to about 800 nm.
