We analyse a recent image authentication scheme designed by Chang et al. [Chang, C.-C., Hu, Y.-S., Lu, T.-C., 2006, A watermarkingbased image ownership and tampering authentication scheme. Pattern Recognition Letters. 27, 439-446] whose first step is based on a watermarking scheme of Maniccam and Bourbakis [Maniccam, S.S., Bourbakis, N., 2004, Lossless compression and information hiding in imag...

The diagnostic characters of the Chinese planthopper genus Tetricodes Fennah, 1956 are redefined. Three new species of this genus, T. ansatus Chang & Chen, sp. n.

Wild, liquid state culture and solid state culture of Taiwanofungus camphoratus (Chang-chih) were sequentially extracted with cold water, methanol, and hot water to get cold water soluble, methanol soluble, and hot water soluble extracts respectively. The extracts from three Chang-chih were used to determine 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, semicarbazide sensitive amine ...

The use of the Cartesian diver as a micromanometer was first described by Linderstrem-Lang (1937). Boell, Needham & Rogers (1939) adapted the method to the measurement of the respiration of fragments of amphibian embryos and, in this and subsequent papers, many details of technique were worked out (see Needham, Rogers & Shen Shih-Chang, 1939). Boell, with other collaborators, has used the techn...
