Regulating the Internet: China’s Law and Practice  [PDF]
Haiping Zheng
Beijing Law Review (BLR) , 2013, DOI: 10.4236/blr.2013.41005
Abstract:

Though internet was not commercially available in China until 1995, it has been growing tremendously over the years. At the same time, the Chinese government has never ceased regulating or even censoring internet. This paper provides an overview of the development of internet in China, and the major regulatory schemes that have a direct impact on internet speech. Further, it describes some of the specific measures the Chinese government uses to control the internet: filtering and blocking, imposing liabilities on private parties, access control, internet “police”, and “guiding” public opinion. Finally, it concludes that internet censorship does more harm than good.

Modern Applied Science , 2010, DOI: 10.5539/mas.v4n9p103
Abstract: According to the characteristics of beer brewing wastewater, Up-flow Anaerobic Sludge Bed and Membrane Bio-Reactor integrated technics (UASB+MBR) was applied. This paper investigated various operating parameters during the process of wastewater treatment in MBRs. The sludge loading and the membrane fouling were analyzed by detecting the sludge concentration and sludge characteristics. The results showed that when CODCr, NH4-N, T-P and T-N concentrations of the feed water were 500~1000mg/L, 20~30mg/L, 0.6~14mg/L and 19.5~41.1mg/L, respectively, it got some conclusions in the process.(1)The CODCr , NH4-N , T-P and T-N of MBR effluent could reduce to 40mg/L, 2.3mg/L , 0.3mg/L, 3mg/L, respectively. The quality of the effluent water in this system met the reuse of urban recycling water—Water quality standard landscaping water according to GB/T18921-2002; (2)The DO of the aerobic pool should be controlled at the range of 2~4mg/L, which could increase the removing efficiency of the NH4-N. (3)Appropriate adjustments to the volume of sludge and maintain the sludge concentration of membrane pool at 6~8g /L, which could reduce the velocity of membrane fouling. (4) With 1000mg/L of sodium hypochlorite and 2000mg/L hydrochloric acid alternate cleaning, the recovery of membrane flux can maintain above 95%.
Sinorhizobium meliloti nifA gene exerts a pleiotropic effect on nodulation through the enhanced plant defense response
XiaoTao Chen,HuaSong Zou,ZhenHua Yao,HaiPing Cheng,XiaoMi Dai,JiaBi Zhu,GuanQiao Yu
Chinese Science Bulletin , 2007, DOI: 10.1007/s11434-007-0427-2
Abstract: Sinorhizobium meliloti nifA gene is required for the expression of a bunch of nif and fix genes. Here, we report its pleiotropic effects on the nodule formation. Compared with wild type strain, nifA mutant significantly reduced nodule suppression rate in split-root system. The plants inoculated with mutant strain produced lower amount of daidzein and less necrotic cells on their roots. In addition, the defense genes failed to be evoked by nifA mutant at the early nodulation stage. These findings indicated that host defense response was one of the mechanisms mediated by nifA gene to regulate nodule formation during symbiosis. Even though nifA mutant could increase the number of nodules in host plant, it synthesized lower Nod factors than wild type. This suggested that nifA gene mediated multiple and diverse instances in nodulation formation.

Abstract: Six types of bovine somatic cell lines, including a granulosa cell line of Chinese red-breed yellow cattle (YGR), a granulosa cell line of Holstein cow (HGR), two skin fibroblast cell lines of two adult Holstein cows respectively (AFB1 and AFB2), a skin fibroblast cell line (FFB) and an oviduct epithelial cell line (FOV) of a Holstein fetus, were established. Somatic cell nuclear transfer (SCNT) was carried out using these cells as nuclei donor, and a total of 12 healthy calves were cloned. The effects of different types of donor cells on developmental potential of bovine SCNT embryos were investigated, (i) There was no significant difference in development rates to the blastocyst stage for SCNT embryos from YGR and HGR (33.2% and 35.1%, respectively). Pregnancy rates of them were 33.3% and 30.2%, respectively; and birth rates were 16.7% and 11.6%, respectively, (ii) Development rates to the blastocyst stage for SCNT embryos from diffetent individuals (AFB1 and AFB2) differed significantly (27.9% and 39.4%, respectively, P < 0.05). Pregnancy rates of them were 36.2% and 36.4%, respectively; and birth rates were 14.9 % and 27.3%, respectively, (iii) There was significant difference in development rates to the blastocyst stage for SCNT embryos from FFB and FOV of the same fetus (37.9% and 41.5%, respectively,P < 0.05). Pregnancy rates of them were 45.7% and 24.1%, respectively; and birth rates were 22.9 % and 10.3%, respectively. Finally, developmental potential of bovine SCNT embryos from all four types of somatic cells from Holstein cows (HGR, AFB, FFB and FOV) were compared. Forin vitro development stage, development rates to the blastocyst stage for SCNT embryos from HGR, AFB, FFB and FOV were 35.1%A, 29.4%B, 37.9%A and 41.5%C, respectively (P ABC < 0.05); forin vivo development stage, pregnancy rates of them were 30.2%, 36.2%, 45.7% and 24.1%, respectively; and birth rates of them were 11.6%, 17.2%, 22.9% and 10.3% respetively.

Chinese Science Bulletin , 2005, DOI: 10.1007/BF03183656
Abstract: Somatic cell clone technology is a viable approach to preserving endangered livestock and wildlife genetic resources. In the present research, somatic cell nuclear transfer (SCNT) was performed using granulose cells from the critical endangered Chinese red-cross yellow cattle as donor cells. A total of 211 oocytes were manipulated and 166 (79%) of them were successfully enucleated. 112 (67.4%) SCNT embryos were reconstructed, 94 (83%) of them cleaved, and 48 (43%) of them developed to blastocyst stage. SCNT blastocysts were transferred to 6 Holstein recipients, and 2 (33%) of them were found to be pregnant. One of them maintained to term and delivered a calf, whereas another aborted. Effect of different fusion buffer (mannitol vs. Zimmerman fusion buffer) and different activation methods (calcium ionophore+6-DMAP vs. cycloheximide+CB) on fusion rate and development of SCNT embryos were investigated. The results indicated that: (i) on condition of two DC pulses of 2.5 kV/cm for 10 μs each, fusion rates were higher in mannitol solution than in Zimmerman fusion buffer (71% vs. 61%, respectively, p<0.05=, but the blastocysts rates did not differ between two treatments (36% vs. 39%, p>0.05); (ii) There was no significant difference in development rates to the blastocyst stage for SCNT embryos activated by calcium ionophore+6-DMAP or by cycloheximide+CB (42% vs. 46%, respectively, p>0.05). Microsatellite DNA analysis examining 28 loci confirmed that the cloned calf was genetically identical to the donor Jinan red-cross yellow cattle and different from the recipient females. Growth and reproductive performance of cloned cow were evaluated, and there were no differencei cross-red n it between cloned and normal control Jinan yellow cattle. Furthermore, the cloned yellow cow has delivered a healthy yellow calf.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0061341
Abstract: The purpose of the present work was to determine the incidence and clinical implications of somatic EZH2 mutations in 714 patients with de novo acute myelogenous leukemia by sequencing the entire coding region. EZH2 mutations were identified in 13/714 (1.8%) of AML patients were found to be more common in males (P = 0.033). The presence of EZH2 mutations was significantly associated with lower blast percentage (21–30%) in bone marrow (P<0.0001) and -7/del(7q) (P = 0.025). There were no differences in the incidence of mutation in 13 genes, ASXL1, CBL, c-KIT, DNMT3A, FLT3, IDH1, IDH2, MLL, NPM1, NRAS, RUNX1, TET2, and WT1, between patients with and without EZH2 mutations. No difference in complete remission, event-free survival, or overall survival was observed between patients with and without EZH2 mutation (P>0.05). Overall, these results showed EZH2 mutation in de novo acute myeloid leukemia as a recurrent genetic abnormality to be associated with lower blast percentage in BM and -7/del(7q).

Journal of Clinical Hepatology , 2013,
Abstract: ObjectiveTo evaluate the abnormal methylation of p14, p15, p16, and RB in the cancerous tissues of liver cancer patients and to investigate the significance of detection of multigene methylation for the early diagnosis of liver cancer. MethodsMethylation-specific PCR was used to evaluate the methylation status of p14, p15, p16, and RB in the cancerous tissues of 44 liver cancer cases and the cirrhotic tissues of 41 liver cirrhosis cases as well as the paracancerous tissues of the 44 liver cancer cases. The obtained data were subjected to chi-square test and Fisher′s exact test. ResultsAmong the 41 liver cirrhosis cases, the methylation of p14, p15, p16, and RB was detected in 7 cases (17.1%), 11 cases (28.9%), 15 cases (36.6%), and 3 cases (7.3%), respectively. Among the 44 liver cancer cases, the methylation of p14, p15, p16, and RB was detected in 15 cases (34.1%), 25 cases (56.8%), 31 cases (70.5%), and 12 cases (273%), respectively. In the 44 paracancerous tissues, p16 methylation was detected in 4 cases, and p15 methylation in 1 case. The methylation rates of the four genes were significantly higher in liver cancer tissues and liver cirrhosis tissues than in paracancerous tissues (P<0.05). There were no significant differences in the methylation rates of the four genes among liver cancer patients with different ages, sexes, degrees of tumor differentiation, and clinical stages (P>0.05). ConclusionThe methylation of p14, p15, p16, and RB is frequent in the pathogenesis of liver cancer. The detection of multigene methylation is of certain significance for early diagnosis of liver cancer.
Message passing algorithms for the Hopfield network reconstruction: threshold behavior and limitation
Haiping Huang
Physics , 2010, DOI: 10.1103/PhysRevE.82.056111
Abstract: The Hopfield network is reconstructed as an inverse Ising problem by passing messages. The applied susceptibility propagation algorithm is shown to improve significantly on other mean-field-type methods and extends well into the low temperature region. However, this iterative algorithm is limited by the nature of the supplied data. Its performance deteriorates as the data becomes highly magnetized, and this method finally fails in the presence of the frozen type data where at least two of its magnetizations are equal to one in absolute value. On the other hand, a threshold behavior is observed for the susceptibility propagation algorithm and the transition from good reconstruction to poor one becomes sharper as the network size increases.
