Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A short-chain peptide capable of controlling spermatozoa fertilization performance is supplied in an in vitro culture medium of spermatozoa and oocytes to increase the success rates of in vitro fertilization. The short-chain peptide comprises an amino acid sequence H-Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-X-NH2 (SEQ ID NO: 1), where X denotes Tyr or Phe, and the sequence ends with an amide. The short-chain peptide is conducive to adjustment of the concentration of free calcium ions inside the cells of the spermatozoa and thus enhancement of the success rates of in vitro fertilization.

Abstract: A circuit substrate includes an electrically conductive layer having electrically conductive patterns formed therein, an insulating layer having a through hole, and a composite layer positioned between the electrically conductive layer and the insulating layer. The through hole is configured for having an electronic component mounted thereon. The composite layer includes a polymer matrix and at least one carbon nanotube bundle embedded in the polymer matrix. One end of the at least one carbon nanotube bundle contacts the electrically conductive patterns, and the other is exposed in the through hole of the insulation layer.
