Lasers that transmit data on optical fibers do not produce monochromatic light. Instead, they provide a narrow spectrum that includes many wavelengths. The physical characteristics of optical fibers ...

To know the properties of a particle or a wave, one should measure how its energy changes with its momentum. The relation between them is called the dispersion relation, which encodes essential ...

The aim of this study was to investigate the effect of obesity on dispersion of P-wave duration and QTc interval in obese women. Forty-two obese women (Body mass index (BMI)=40±3 kg/m 2, mean age 45±9 ...
