Evolution Korea In the fight over evolution, Korean scientists aren't taking their chances. The Society for Textbook Revise has been fighting to eliminate Archaeopteryx as well as horses and other evolutionary icons from textbooks. Confucian practices that emphasize global success and the value of learning, still dominate the country's culture. However, Korea is looking for a new development paradigm. Origins The growth of Iron Age cultures brought more sophisticated states to the Korean Peninsula, such as Goguryeo and Baekje. Each of them developed a unique cult

We propose an eight-spatial-mode ring-core few-mode fiber (RC-FMF), utilizing the cross-arranged different-material-filling side holes (CA DMFSH) for effective index difference improvement. Two GeO2-doped-silica side holes and two air-filling side holes are arranged orthogonally around the ring core, which have directionally different effects on the refractive index and the mode field distribution in the RC-FMF. The results indicate that the effective index difference (Δneff) between adjacent spatial modes is larger than 1.96×10-4, a
