The unique wettability of organisms gives inspiration to design and create new interface materials. This review focuses on the recent research progress of femtosecond laser micro/nano fabrication for bioinspired superhydrophobic or underwater superoleophobic surfaces. This review starts with a presentation of the related background including the advantages of femtosecond laser and wettability theoretical basis. Then, organisms with unique wettability in nature, the preparation of superhydrophobic or underwater superoleophobic surfaces by femtosecond lasers on different materials, and their related important applications are introduced. Finally, the current challenges and future prospects with regard to this field are provided.展开更多

The code can greatly reduce the encoding complexity while maintaining the same decoding complexity as traditional regular LDPC （H-LDPC） codes defined by the sparse parity check matrix. Simulation results show that the performance of the proposed irregular LDPC codes can offer significant gains over traditional LDPC codes in low SNRs with a few decoding iterations over an additive white Gaussian noise （AWGN） channel.展开更多

As a result, marine accidents, such as collisions or grounding, may occur, particularly in inshore areas. On coasts where earthquakes and tsunamis occur frequently, such as the Japanese coast, a tsunami that advances into a bay from the open sea is influenced by the submarine topography. It grows into a huge wave that could cause tremendous damage to ships under way and at anchorage. A massive earthquake occurred in the Tohoku and Kanto regions of Japan on March 11,2011. In response, a tsunami alert, a tsunami warning and an advisory were issued for the entire Pacific coast region. This research investigates the evacuation behaviour of ships by AIS （automatic identification system） data in Tokyo Bay after the tsunami warning was issued. The unusual behaviour observed was attributed to the emergency evacuation of ships.展开更多

The experiment was designed to evaluate NAA, over a range of concentrations （15, 20 and 30 ppm） when applied alone, and BA ＋ NAA combinations （BA--60, 100, 120 or 140 ppm ＋ NAA 5 ppm） for thinning the assessed apple cultivars. All the applied treatments with NAA and BA ＋ NAA adequately thinned ＂Senabija＂ and ＂Ko2ara＂, whereas application of NAA 20 ppm and 30 ppm and combined treatment BA 140 ppm ＋ NAA 5 ppm were effective fruit thinners for ＂Pasinka＂. In terms of the average fruit weight and number of fruits categorized as large （〉 75 mm or 〉 65 ram）, as well as from the aspect of fruit number per trunk cross-sectional area, the variant of treatment BA 140 ppm ＋ NAA 5 ppm was most effective on ＂Senabija＂ and ＂Paginka＂, whereas BA 100 ppm ＋ NAA 5 ppm had the best effect on ＂Kozara＂.展开更多
