A New Specific Property of Schweizer-Sklard Operators
Chunli WANG,Shiqiang ZHANG
Studies in Mathematical Sciences , 2011, DOI: 10.3968/1975
Abstract: A new specific property of Schweizer-Sklard operators is discovered that Schweizer-Sklard operations are continued fuzzy operators. The relation between Schweizer-Sklard operators and other Fuzzy operators is analysis. The conclusion that Schweizer-Sklard operations could partly replace other fuzzy operations most in use is given. At the same time the relation between Schweizer-Sklard operations and Zadeh operations as well as probability operators is given.
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 $\mathcal{C}$.
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.
The Ring-Opening Reaction of 7,7’-Dimethyl-2, 5-bis(trimethylsilyl)-dithieno[2,3-b:3’,2’-d]silole in the Presence of NXS (X = Cl, Br, I)  [PDF]

International Journal of Organic Chemistry (IJOC) , 2011, DOI: 10.4236/ijoc.2011.14024
Abstract: In this paper, the synthetic method for making 7,7’-dimethyl-2,5-bis(trimethylsilyl)-dithieno[2,3-b:3’,2’-d] silole (1) was developed by using 2,2’-dibromo-5,5’-bis-trimethyl-silanyl[3,3’]bithiophenyl as starting material in one pot reaction. In the presence of NXS (X = Cl, Br, I), a novel ring-opening reation was occurred on the silole ring of 1 in DMF or THF. By using such kind of reaction, two types of ring opened products, (2’-halo-5,5’-bis(trimethylsilanyl)[3,3’]bithiophenyl-2-yl)-dimethylsilanols and 2,2’-dihalo-5,5’-bis(trimethylsi- lanyl)[3,3’]bithiophenyls were obtained efficiently.
Dynamic evolution of adhesion force between protein films studied by atomic force microscope
Ming Su,Chen Wang,Chunli Bai
Chinese Science Bulletin , 1998, DOI: 10.1007/BF02883464
Abstract: The approaching of two hydrophobic surfaces in water will lead to the combination of air bubbles adsorbed on the surfaces, thus additional long-range attraction is induced due to the bridging capillary force. Theoretical analysis shows that the process is a first-order phase transition, while no direct experiment supports the predication. The interaction between protein modified tip of atomic force microscope and protein film on mica was studied. The results demonstrate that the adhesion force between them increases to a stable value during the calibration process and the evolution clearly indicates the character of first-order transition.
Positive solutions to nonlinear second-order three-point boundary-value problems for difference equation with change of sign
Chunli Wang,Xiaoshuang Han,Xiaoshuang Li
Electronic Journal of Differential Equations , 2008,
Abstract: In this paper we investigate the existence of positive solution to the discrete second-order three-point boundary-value problem $$displaylines{ Delta^2 x_{k-1}+ h(k) f(x_k)=0, quad k in [1, n], cr x_0 =0, quad a x_l = x_{n+1}, }$$ where $n in [2, infty)$, $l in [1, n]$, $0 < a < 1$, $(1-a)l geq 2$, $(1+a)lleq n+1$, $f in C(mathbb{R}^+,mathbb{R}^+)$ and $h(t)$ is a function that may change sign on $[1, n]$. Using the fixed-point index theory, we prove the existence of positive solution for the above boundary-value problem.

Influence of low energy ballistic electron on the transmittance properties of Au/Si interface studied by ballistic-electron-emission microscope
Xiaohui Qiu,Guangyi Shang,Chen Wang,Naixin Wang,Chunli Bai
Chinese Science Bulletin , 1997, DOI: 10.1007/BF02882760
Abstract: The electronic properties of Au/Si interface are investigated with a homemade ballistic-electron-emission microscope. The spatial distribution of Schottky barrier height is detected. Irreversible changes of ballistic transmittance of local interface with typical size of a few hundred of angstroms in diameter are observed by raising the tip voltage temporarily. Ballistic-electron-emission spectroscopy indicates that the electron transmission probabilities are reduced significantly inside the modified region, which is attributed to the Au-Si intermixing and other chemical reactions occurring at the interfacial layer stimulated by the injected energetic hot electrons.
Temperature Calculation of Pellet Rotary Kiln Based on Texture  [PDF]
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%.
Investigation on the Competition Interaction of Synthetic Food Colorants and Ciprofloxacin Hydrochloride with Bovine Serum Albumin by Fluorescence Spectroscopy
Baosheng Liu,Chao Yang,Jing Wang,Chunli Xue,Yunkai Lü
Journal of Thermodynamics , 2011, DOI: 10.1155/2011/137531
Abstract: The effects of synthetic food colorants like tartrazine (TTZ), sunset yellow (SY), and erythrosine (ETS) on the binding reaction between ciprofloxacin hydrochloride (CPFX) and bovine serum albumin (BSA) were investigated by fluorescence spectroscopy in the aqueous solution of pH = 7.40. Results showed that CPFX caused the fluorescence quenching of BSA through a static quenching procedure and the primary binding site was located at subdomain IIA of BSA (site I). According to the calculated thermodynamic parameters, it confirmed that CPFX bound to BSA by electrostatic interaction. In addition, the colorants affected the formation of BSA-CPFX complex. This resulted in an increase of the free, biological active fraction of CPFX. The binding distance of BSA-CPFX systems was evaluated according to Förster's theory. Results suggested that the binding distance were increased in the presence of synthetic food colorants.
