Abstract: A wide-band and finely gain-flattened hybrid fiber amplifier is realized. The seamless 3.0-, 1.3-, and 1.0-dB bandwidths of 80, 76, and 69 nm with relative gain-flatness of 11.3%, 4.7%, and ...

In this paper, a regular dodecahedron solar simulator structure with five spot light sources is presented to provide uniform flux. To analyze light distribution without a dodecahedron cavity, a cubic ...

Deformational plagiocephaly is when a baby develops a lasting flat spot on one side the head or the back of the head. It happens when a baby sleeps in the same position most of the time or because of ...
