Subarea Tree Routing (STR) in Multi-hop Wireless Ad hoc Networks  [PDF]
Guikai LIU, Chunli SHAN, Gang WEI, Hongjiang WANG
Wireless Sensor Network (WSN) , 2009, DOI: 10.4236/wsn.2009.11006
Abstract: Subarea Tree Routing (STR), a new routing protocol for multi-hop wireless ad hoc networks, is proposed. The novelty of the STR protocol is to divide the whole network into many subareas constructed as a result of establishing subarea trees. Its main idea is to identify root nodes by manual configuration or auto-discovery process firstly, then the root nodes originate the process of establishing subarea trees, and finally each node either joins in a subarea tree or become an interconnect node. STR belongs to hierarchical routing protocol and does not attempt to consistently maintain routing information in every node. Furthermore, through the use of tree’s intrinsic routing function, the STR protocol exhibits hybrid behavior of proactive and on-demand routing protocols. We prove the correctness of STR, and our simulation results show that the pro-posed scheme achieves lower route discovery delays, lower route discovery load and better performance of normalized routing load in large, mobile, ad hoc networks as compared with AODV.

Chunli Lin, Yufan Wu
Intelligent Control and Automation (ICA) , 2017, DOI: 10.4236/ica.2017.82005
Abstract: In order to improve the quality of clinker produced by pellet rotary kiln, flame temperature that it is a very important factor of affecting on the quality of clinker is studied. The flame images collected from pellet rotary kiln are decomposed into three gray images by the method of RGB, so we can get more information of flame. Taking advantage of gray level co-occurrence matrix, the monitoring model for flame temperature based on image texture is established with RGB channels. In order to test the universality of the algorithm, candle flame temperature is detected by this method. The maximum error of the model is less than 3%.

Chunli Yang
Journal of Language Teaching and Research , 2010, DOI: 10.4304/jltr.1.5.738-742
Abstract: Terms of address are frequently used in social communication to show the identity, rank and relationship between the speaker and the hearer. It is important to have a profound understanding of addressing terms, especially in cross-cultural communication. However, due to the difference in history, religion and culture, terms of address vary in different countries and regions. In this paper, the author discusses the translation of English and Chinese addressing terms from the aspect of cultural background. First, the author defines terms of address and gives the reason why people use terms of address in social communication. Then, the differences between English and Chinese terms of address are analyzed from the point of kinship terms and social terms of address. Last, four translation methods are given according to different situations, namely, literal translation, translating flexibly, specification or generalization and domestication and foreignization.

International Business Research , 2009, DOI: 10.5539/ibr.v1n4p104
Abstract: This paper take enterprise's collective brain drain as the research object, by using of questionnaire method, historical data, experts consultation method, and other methods of construct the collective brain drain of forewarning indicators, and then use the alternative ranking method to determine and evaluate comprehensively system of indicators to the weight. By constructing the forewarning system to real-time monitor, identify, diagnose and evaluate the trend of enterprise's collective brain drain and on this basis to pre-control, the prior development of corrective measures, the crisis will be resolved in the embryonic stage. Therefore, constructing the forewarning system of enterprise's collective brain drain for the long-term stable development of enterprises has important practical significance.
Stability of Gorenstein objects in triangulated categories
Zhanping Wang,Chunli Liang
Mathematics , 2014,
Abstract: Let $\mathcal{C}$ be a triangulated category with a proper class $\xi$ of triangles. Asadollahi and Salarian introduced and studied $\xi$-Gorenstein projective and $\xi$-Gorenstein injective objects, and developed Gorenstein homological algebra in $\mathcal{C}$. In this paper, we further study Gorenstein homological properties for a triangulated category. First, we discuss the stability of $\xi$-Gorenstein projective objects, and show that the subcategory $\mathcal{GP}(\xi)$ of all $\xi$-Gorenstein projective objects has a strong stability. That is, an iteration of the procedure used to define the $\xi$-Gorenstein projective objects yields exactly the $\xi$-Gorenstein projective objects. Second, we give some equivalent characterizations for $\xi$-Gorenstein projective dimension of object in $\mathcal{C}$.

Ischemic cerebrovascular disease is a global health problem. According to the World Health Organization, ischemic stroke is actually the most common cause of death in the world. Ginkgo biloba extract (GbE) is a traditional Chinese medicine for angina pectoris. Ginkgo biloba plays a role in expanding blood vessels, increasing coronary and cerebral blood flow, preventing platelet aggregation, inhibiting thrombosis, and improving the microcirculation. In the present study, we investigated the mechanisms involved in the neuroprotective effects of GbE in a model of hypoxic-ischemic brain disease. We used NGF(100 ng/ml for 6 days)and OGD(5% CO2and 95% N2, 1 mmol/l NaS2O4insugar-free DMEM for 16 h) to stimulate PC12 cells and convert them into neurons in order to establish an ischemia model. The results showed that PC12 cells transformed into cells that looked like neurons and that MAP2 was up-regulated in NGF-treated PC12 cells. Cell apoptosis was found to be up-regulated after NGF stimulation and OGD. The apoptosis rate after 16 hours of OGD was 19.44%. GbE (50ng/ml) reduces apoptosis rate to 11.35%. These results may help to show that NGF treatment can be combined with OGD to establish anin vitromodel of acute ischemic brain damage. In the present study, we find that GbE effectively increases the survival rate of PC12 cells and relieves OGD damage. These results suggest that GbE has the neuroprotective effects of ischemic brain damage.

Chinese Studies (ChnStd) , 2013, DOI: 10.4236/chnstd.2013.24031
Abstract: The major purpose of this study was to understand what the reading strategies the EFL students use more or less among EFL college students in Taiwan. The study focused on three hundred and ninety-eight EFL college students coming from seven colleges located in the north, central, and south Taiwan. The research instrument was a questionnaire modified from Wan-Yin Lin’s Chinese reading strategies questionnaire (2005). The collected data used the Statistical Package for the Social Sciences (SPSS) version 13.0 to analyze the results. The findings of study included the following: first, higher grade students had more variety in using reading strategies than lower grade students; and second, the higher grade students tended to use integrated strategies more than lower grade students. According to the research findings, the researcher provided some recommendations, such as teachers could be better guiders to help students understand the importance of reading in language learning. They can not just focus on teaching listening and speaking, and should enhance the balance development in integrated reading strategies that helped students could read fluently any English materials.
Absence of Perfect Conductance Quantization of Helical-edge Transport in Graphene under a Strong, Tilted Magnetic Field
Chunli Huang,Miguel. A. Cazalilla
Physics , 2015, DOI: 10.1103/PhysRevB.92.155124
Abstract: In a recent experiment, Young et al. [Nature {\bf 505}, 528 (2014)] observed a metal to insulator transition as well as transport through helical edge states in monolayer graphene under a strong, tilted magnetic field. Under such conditions, the bulk is a magnetic insulator which can exhibit metallic conduction through helical edges. It was found that two-terminal conductance of the helical channels deviates from the expected quantized value at low-temperatures ($=e^2/h$ per edge, at zero temperature). Motivated by this observation, we study the effect of disorder on the conduction through the edge channels. We show that, unlike the situation in semiconducting quantum wells, a disorder Rashba spin-orbit coupling does not lead to backscattering, at least to leading order. Instead we find the lack of perfect anti-alignment of the electron spins in the helical channels to be the most likely source for backscattering arising from scalar (i.e. spin-independent) impurities. The intrinsic spin-orbit coupling and other time-reversal symmetry breaking and/or sublattice-parity breaking potentials also lead to (sub-leading) corrections to the channel conductance.
