    Abstract In this paper, we propose a novel joint data-hiding and compression scheme for digital images using side match vector quantization (SMVQ) and image inpainting. The two functions of data hiding and image compression can be integrated into one single module seamlessly. On the sender side, except for the blocks in the leftmost and topmost of the image, each of the other residual blocks in raster-scanning order can be embedded with secret data and compressed simultaneously by SMVQ or image inpainting adaptively according to the current embedding bit. Vector quantization is also utilized for some complex blocks to control the visual distortion and error diffusion caused by the progressive compression. After segmenting the image compressed codes into a series of sections by the indicator bits, the receiver can achieve the extraction of secret bits and image decompression successfully according to the index values in the segmented sections. Experimental results demonstrate the effectiveness of the proposed scheme.

    Abstract Galectin-3 consists of an unstructured N-terminal domain (NTD) and a structured carbohydrate-recognition domain and agglutinates neutrophils and glycosylated molecules in the extracellular milieu. Here the authors combine biophysical and biochemical experiments with NMR measurements and show that the galectin-3 NTD undergoes liquid-liquid phase separation (LLPS) and agglutinates other molecules through this process.

    Abstract Description and photos of main characters of Wiesnerella denudata (Mitt.) Steph. in Taiwan are provided. Sequence of chloroplast DNA rbcL and SEM photos of spores and elaters from Taiwan’s material are provided for the first time, which can be compared with materials from adjacent areas to show variation of the species. Three substitutions were found between plants of Taiwan and Nepal in rbcL sequences. Three morphological characters of spores are differentiated between the plants of Taiwan and mainland China. Spores are smaller in Taiwanese plant, 34-38 against 78.3-86.1 μm in diameter. Spore equatorial belt does not have any opening in Taiwan’s plant, but three openings are described in plant from mainland China. Exine is reticulate throughout the spore in Taiwanese plant, but it is restricted to the proximal surface of spore in plant from mainland China.
