提出一种用于JPEG图像的高容量可逆水印算法。该算法利用JPEG图像DCT系数的零系数间隔确定修改的位置,利用间隔中零系数的个数确定水印嵌入量,进而嵌入水印信息。这样做不会带来如位置图等任何额外信息。该算法利用零系数间隔准确地提取水印,并能在水印提取后无损地恢复原始JPEG图像。实验结果表明,该算法在嵌入大量水印信息的情况下仍能取得满意的PSNR值,且图像文件大小的增加较小。

The mammalian central nervous system(CNS) is considered an immune privileged system as it is separated from the periphery by the blood brain barrier(BBB). Yet,immune functions have been postulated to heavily infiuence the functional state of the CNS, especially after injury or during neurodegeneration. There is controversy regarding whether adaptive immune responses are beneficial or detrimental to CNS injury repair. In this study, we utilized immunocompromised SCID mice and subjected them to spinal cord injury(SCI). We analyzed motor function, electrophysiology, histochemistry, and performed unbiased RNA-sequencing. SCID mice displayed improved CNS functional recovery compared to WT mice after SCI. Weighted gene-coexpression network analysis(WGCNA) of spinal cord transcriptomes revealed that SCID mice had reduced expression of immune function-related genes and heightened expression of neural transmission-related genes after SCI,which was confirmed by immunohistochemical analysis and was consistent with better functional *** analyses also indicated heightened expression of neurotransmission-related genes before injury in SCID mice, suggesting that a steady state of immune-deficiency potentially led to CNS hyper-connectivity. Consequently, SCID mice without injury demonstrated worse performance in Morris water maze test. Taken together, not only reduced infiammation after injury but also dampened steady-state immune function without injury heightened the neurotransmission program, resulting in better or worse behavioral outcomes respectively. This study revealed the intricate relationship between immune and nervous systems, raising the possibility for therapeutic manipulation of neural function via immune modulation.

[Objectives] The paper was to explore the control effects of different botanical pesticides against Empoasca pirisuga Matumura. [Methods] 5% Eucalyptol SL, 0.5% matrine SL and 50% thiacloprid WDG were used to control E. pirisuga , and the decline rate of insect population was investigated. [Results] Eucalyptol had good control effect on E. pirisuga , with slow effect but long duration. It was harmless to natural enemies in tea gardens, with high safety and no chemical injury. [Conclusions] The study provides a theoretical basis for the application of botanical pesticides in tea production.
