MAC Frame Resolution and PHY Protocol Type Detection of IEEE 802.11  [PDF]
Ling Li, Shi Peng, June Li, Kai Yuan, Zhihao Wang, Yinbin Liu, Ping Chen, Xianbing Wang
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2017, DOI: 10.4236/ijcns.2017.105B005
Abstract:
Frame resolution and physical layer (PHY) protocol type detection are the basis of research and development of intrusion prevention systems for IEEE 802.11 wireless network. Aiming at the problems which cannot be solved by the specifications export, this paper proposed a MAC frame analytical method and a PHY protocol type detection algorithm based on parsing the IEEE 802.11packets captured by the library Libpcap. The packet structure and the length of the frame preamble (18 or 26 bytes) are presented. Then the methods of transforming byte-order and resolving sub-fields are given. A detection algorithm of PHY protocol type is proposed based on the experiments and examples are given to verify these methods. This work can be a reference for the R & D related to link layer frame analysis.
Citizen Complaints about Environmental Pollution: A Survey Study in Suzhou, China
Xianbing Liu,Yanli Dong,Can Wang,Tomohiro Shishime
Journal of Current Chinese Affairs , 2011,
Abstract: This paper discusses environmental complaints made by citizens living close to industrial polluters in China. Data collected from a questionnaire survey in Suzhou City is used for the analysis. The results confirm a marginal level of citizen environmental complaints in the study area at present. Meaningful findings include the fact that citizens have a tendency to complain collectively, and that perception of the level of environmental information provided by companies significantly determines a citizen’s likelihood of lodging environmental complaints. Therefore, the disclosure of corporate environmental information must be emphasized continuously; citizens must be encouraged to correctly understand the environmental performance of companies so that they might make appropriate complaints. Governments need to show their support for citizen-led environmental complaint initiatives. The successful cases would convince them to keep a closer eye on their neighbouring polluters.
Exploring scientists' working timetable: Do scientists often work overtime?
Xianwen Wang,Shenmeng Xu,Lian Peng,Zhi Wang,Chuanli Wang,Chunbo Zhang,Xianbing Wang
Computer Science , 2012, DOI: 10.1016/j.joi.2012.07.003
Abstract: A novel method is proposed to monitor and record scientists' working timetable. We record the downloads information of scientific papers real-timely from Springer round the clock, and try to explore scientists' working habits. As our observation demonstrates, many scientists are still engaged in their research after working hours every day. Many of them work far into the night, even till next morning. In addition, research work also intrudes into their weekends. Different working time patterns are revealed. In the US, overnight work is more prevalent among scientists, while Chinese scientists mostly have busy weekends with their scientific research.
Exploring Scientists' Working Timetable: A Global Survey
Xianwen Wang,Lian Peng,Chunbo Zhang,Shenmeng Xu,Zhi Wang,Chuanli Wang,Xianbing Wang
Computer Science , 2013, DOI: 10.1016/j.joi.2013.04.003
Abstract: In our previous study (Wang et al., 2012), we analyzed scientists' working timetable of 3 countries, using realtime downloading data of scientific literatures. In this paper, we make a through analysis about global scientists' working habits. Top 30 countries/territories from Europe, Asia, Australia, North America, Latin America and Africa are selected as representatives and analyzed in detail. Regional differences for scientists' working habits exists in different countries. Besides different working cultures, social factors could affect scientists' research activities and working patterns. Nevertheless, a common conclusion is that scientists today are often working overtime. Although scientists may feel engaged and fulfilled about their hard working, working too much still warns us to reconsider the work - life balance.

Chinese Science Bulletin , 2005, DOI: 10.1007/BF02897570
Abstract: Functional analysis for gene silencing suppressor of P14 geneof Beet necrotic yellow vein virus and S6 gene ofRice black streak dwarf virus was carried out by agro-infiltration with recombinant vectors ofPotato virus X. The phenotype observation of green fluorescent protein (GFP) expression and Northern blot showed that the gene silencing ofgfp transgenicNicotiana benthamiana induced by homologous sequence was strongly suppressed by the immixture infiltration of either the P14 or the S6. In the suppressed plants, thegfp mRNA accumulation was higher than that in the non-suppressed controls and the symptoms caused by PVX infection became more severe, especially thegfp DNA methylation of plant genome was significantly inhabited when co-infiltrated with RBSDV S6 gene. These results suggested that these two virus genes were potentially to encode for proteins as RNA silencing suppressors.

Abstract: Background Beet necrotic yellow vein virus (BNYVV), encodes either four or five plus-sense single stranded RNAs and is the causal agent of sugar beet rhizomania disease, which is widely distributed in most regions of the world. BNYVV can also infect Nicotiana benthamiana systemically, and causes severe curling and stunting symptoms in the presence of RNA4 or mild symptoms in the absence of RNA4. Results Confocal laser scanning microscopy (CLSM) analyses showed that the RNA4-encoded p31 protein fused to the red fluorescent protein (RFP) accumulated mainly in the nuclei of N. benthamiana epidermal cells. This suggested that severe RNA4-induced symptoms might result from p31-dependent modifications of the transcriptome. Therefore, we used next-generation sequencing technologies to analyze the transcriptome profile of N. benthamiana in response to infection with different isolates of BNYVV. Comparisons of the transcriptomes of mock, BN3 (RNAs 1+2+3), and BN34 (RNAs 1+2+3+4) infected plants identified 3,016 differentially expressed transcripts, which provided a list of candidate genes that potentially are elicited in response to virus infection. Our data indicate that modifications in the expression of genes involved in RNA silencing, ubiquitin-proteasome pathway, cellulose synthesis, and metabolism of the plant hormone gibberellin may contribute to the severe symptoms induced by RNA4 from BNYVV. Conclusions These results expand our understanding of the genetic architecture of N. benthamiana as well as provide valuable clues to identify genes potentially involved in resistance to BNYVV infection. Our global survey of gene expression changes in infected plants reveals new insights into the complicated molecular mechanisms underlying symptom development, and aids research into new strategies to protect crops against viruses.

Abstract: In order to investigate COD removal and nitrification efficiencies in single(C/N) and two-stage BAF(C+N) processes for treating domestic wastewater,two parallel operated BAF processes were carried out under the same aeration rate,HRT,temperature and influent wastewater quality.The results showed that the separation of COD removal and nitrification led to higher treatment performance than single-stage BAF process.BAF C had higher organic removal loading rate than BAF C/N,and the effluent COD concentration was stably lower than 50 mg/L.The effluent NH+4-N concentration of BAF C/N and BAF C+N processes were 5~12 mg/L and lower than 5 mg/L,respectively,and nitrification occurred in BAF N at pH<6.3.The lower part of BAF N had highly microbial activity,the average specific oxygen uptake rate(SOUR) was 32 mg O2/(g VAS·h).Backwash of BAF C was the same as BAF C/N,while the backwash intervals of BAF N was extended to 5~7 days,which may reduce the energy and water consumption.

Abstract: Sewage sludge was pretreated by steam explosion and then developed into the organo inorganic compound fertilizer through incorporating with a given amount of chemical fertilizers. The field experiment was conducted to assess the effect of pretreated sludge and the compound fertilizer on the no heading Chinese cabbage yield,soil fertility and nutrient bioavailability. The process of steam explosion can eliminate pathogen and disgusted odor in sewage sludge within a relative short time. The loss of total organic C, N and P of sewage sludge is negligible by steam\|exploded treatment, but the dissolved organic C, available N and P in the pretreated sludge can be increased significantly by 87%, 19% and 35%, respectively. Compared to inorganic compound fertilizer on basis of equal nutrient input, the application of the sludge compound fertilizer elevated vegetable yield by 38%, the bioavailablity of N and P and reduced nitrate content in plant by about 50%. The higher concentration of Vc and total sugar in the plants grown in the plots amended with sludge, pretreated sludge, and sludge compound fertilizer were also observed in this study.
