Abstract: A gene editing system of Candida viswanathii includes a Candida viswanathii, a first gene editing fragment and a second gene editing fragment. The first gene editing fragment successively includes a first homology arm and a screening gene. The second gene editing fragment is connected to a C-terminus of the first gene editing fragment and includes a second homology arm, a Cas9 expression cassette and a sgRNA cassette. The Cas9 expression cassette successively includes a Cas9 promoter, a Cas9 gene and three nuclear localization sequences. The sgRNA cassette successively includes a sgRNA promoter, a first ribozyme, a targeting sequence, a scaffold and a second ribozyme. The first gene editing fragment and the second gene editing fragment are constructed as a linear fragment for gene editing of a chromosome of the Candida viswanathii.

Abstract: A compact optical imaging device with shortened focal length, for use in an imaging module and an electronic device, comprises first to fifth lenses. An image-side surface of the first lens is concave near an optical axis. An image-side surface of the third lens is concave near the optical axis. The second and fourth lenses have a negative refractive power. The third and fifth lenses have a positive refractive power.

Abstract: The present invention provides a multiply built up buffer structure and a manufacturing thereof. The buffer structure includes at least two buffer members and a pair of end caps. The buffer member is made of paper material, having an elongate strip configuration having a U-shaped cross-section forming a hollow chamber shaped to correspond to the configuration thereof. The hollow chamber extends between and completely through opposite ends of the buffer member. One of the buffer members is movably received in the hollow chamber of the other buffer member to form an extendible strip. The end cap is made of paper material, having a U-shaped configuration forming therein a hollow chamber corresponding in shape to the configuration thereof. The hollow chamber extends between and completely through opposite ends of the end cap. The hollow chamber of the end cap receives at least one reinforcement piece made of paper material therein.
