Remote sensing image segmentation is the basis of image understanding and analysis. However,the precision and the speed of segmentation can not meet the need of image analysis,due to strong uncertainty and rich texture details of remote sensing images. We proposed a new segmentation method based on Adaptive Genetic Algorithm(AGA) and Alternative Fuzzy C-Means(AFCM) . Segmentation thresholds were identified by AGA. Then the image was segmented by AFCM. The results indicate that the precision and the speed of segmentation have been greatly increased,and the accuracy of threshold selection is much higher compared with traditional Otsu and Fuzzy C-Means(FCM) segmentation methods. The segmentation results also show that multi-thresholds segmentation has been achieved by combining AGA with AFCM.

Recent studies showed that pseudogenes can regulate the expression of their coding gene partners by competing for miRNAs. The E2F family plays a crucial role in the control of cell cycle checkpoint. E2F3P1 is a pseudogene of E2F3. Few studies focused on genetic variations on pseudogenes. In this study, we performed a case-control study to assess the association between single nucleotide polymorphisms （SNPs） in E2F3P1 and hepatocellular carcinoma （HCC） risk in 1050 hepatitis B virus （HBV）-positive HCC cases and 1050 chronic HBV carders. Logistic regres- sion analysis was applied to estimate odds ratios （ORs） and 95% confidence intervals （CIs） for the associations between genotypes and HCC risk. We found that the variant CT/TT genotypes of rs1838149 were associated with a significantly decreased risk of HCC （adjusted OR = 0,66, 95% CIs = 0.51-0.86, P = 0.002） compared to those with wildtype CC homozygote. Furthermore, the AA genotype of rs9909601 had an increased HCC risk with an adjusted OR of 1.41 （95% CIs = 1.07-1.86）, and the A allele of rs9909601 was significantly associated with HCC risk com- pared to those with the G allele （adjusted OR = 1.17, 95% CIs = 1.03-1.33, P = 0.017）. These results indicate that genetic variations in the pseudogene E2F3P1 may confer HCC risk.

Certain pseudogenes may regulate their protein-coding cousins by competing for miRNAs and play an active biological role in cancer. However, few studies have focused on the association of genetic variations in pseudogenes with cancer prognosis. We selected six potentially functional single nucleotide polymorphisms （SNPs） in cancerrelated pseudogenes, and performed a case-only study to assess the association between those SNPs and the prognosis of hepatocellular carcinoma （HCC） in 331 HBV-positive HCC patients without surgical treatment. Log-rank test and Cox proportional hazard models were used for survival analysis. We found that the A allele of rs9909601 in E2F3P1 was significantly associated with a better prognosis compared with the G allele [adjusted hazard ratio （HR） = 0.69, 95% confidence interval （CI） = 0.56-0.86, P = 0.001]. Additionally, this protective effect was more predominant for patients without chemotherapy and transcatheter hepatic arterial chemoembolization （TACE） treatment. Interestingly, we also detected a statistically significant multiplicative interaction between genotypes of rs9909601 and chemotherapy or TACE status on HCC survival （P for multiplicative interaction 〈 0.001）. These findings indicate that rs9909601 in the pseudogene E2F3P1 may be a genetic marker for HCC prognosis in Chinese.

In this paper, we propose a strategy of maintaining cache consistency in wireless mobile environments, which adds a validation server （VS） into the GPRS network, utilizes the location information of mobile terminal in SGSN located at GPRS backbone, just sends invalidation information to mobile terminal which is online in accordance with the cached data, and reduces the information amount in asynchronous transmission. This strategy enables mobile terminal to access cached data with very little computing amount, little delay and arbitrary disconnection intervals, and excels the synchronous IR and asynchronous slate （AS） in the total performances.
