With years of vegetation restoration and check dam construction on the Loess Plateau, the sediment load of the middle reaches of the Yellow River have decreased sharply; however, the effects of check dam on this decrease of sediment load with such extensive vegetation restoration remains unclear.In order to further clarify the effects of check dam
Digital watermarking technique emerged as a tool for protecting the multimedia data from copyright infringement.In digital watermarking an imperceptible signal is embedded into the host image, which uniquely identifies the ownership.In the proposed algorithms, DNA sequence is used as a digital watermark, as the DNA sequences are unique and difficul

Abstract Hip joint replacements represent the most effective way of treatment for patients suffering from joint diseases.Despite the rapid improvement of implant materials over the last few decades, limited longevity associated with wear-related complications Fountain persists as the main drawback.Therefore, improved tribological performance is req
Crassulacean acid metabolism (CAM) photosynthesis is a modification of the core C3 photosynthetic pathway that improves the ability of plants to assimilate carbon in water-limited environments.CAM plants fix CO2 mostly at night, when transpiration rates are low.All of the CAM pathway genes exist in Accessories ancestral C3 species, but the timing a
