Journal of Jilin University Science Edition. 2017, 55 (04):  909-914. 
Abstract ( 222 )   PDF (1960KB) ( 158 )  
In order to segment the information of skin color in the image effectively, we proposed a algorithm of skin color segmentation based on texture and neighborhood information of skin point. Firstly, according to the distribution of skin color point in the image in RGB color space, we used the statistical histogram model to segment the part of skin color in the image initially. And then, in order to extract the texture information in the image, we used the Gabor filter to further filter out the part of closing to human skin color but the texture was rough. Finally, we used the  skin color point in the mask image as the seed point to diffuse neighborhood information, and then got the final mask image. The experimental results show that, compared with the skin color model of statistical histogram, the method is better in skin color segmentation.

In the case of large area and low distribution density of nodes, the accuracy of localization algorithm was too low because of the excessive measurement error between nodes. The author proposed a node localization algorithm based on dividing the information of each neighbor node into several local network blocks. The algorithm first combined wireless sensor network node localization technology with the dimensionality reduction method in machine learning domain, and then according to the rule of the closer the distance between the nodes, the measurement accuracy would be the higher, relying on the information related to a certain communication radius of each neighbor node to build network blocks. Finally, the network block was built into a global coordinate system, and the coordinates of each node were mapped by using the global as well as the detailed information of anchor nodes.

Journal of Jilin University Science Edition. 2017, 55 (04):  957-963. 
Abstract ( 186 )   PDF (1267KB) ( 292 )  
We proposed a directed diffusion routing protocol based on clusterhead path transformation in wireless sensor network (DDCPT) to resolve the problem of huge energy consumption at interests flood stage and the maintenance of optimal path in directed diffusion. Firstly, the protocol divided the network into clusters by combining uneven clustering, and spread the interest messages to clusterhead at interests flood stage, thus reducing the energy consumption. Secondly, the next hop clusterhead with the highest priority was selected in clusterhead to build optimal path, and then the followup data was transmitted. Until a clusterhead’s remaining energy of the optimal path was close to the threshold, the network converted the optimal path to continue transferring the data through selecting the succeed transmission node with clusterhead’s backtracking iterative query mechanism based on time. The simulation results show that the protocol can effectively prolong the network lifetime, improve the energy utilization efficiency, and balance the energy consumption of network.

Applying the compressive sensing theory to the decoding of the linear block code, we proposed the compressive sensing model of the reconstructing the error pattern [WTHX]E[WT], the check matrix [WTHX]H[WT] as the form and properties of the measurement matrix. The syndrome [WTHX]S[WT] was used as the measurement signal, the check matrix [WTHX]H[WT] was used as the measurement matrix, and the cyclic code (15,7) was used as the example to reconstruct the estimation of the error pattern [WTHX]E[WT] by using the basis pursuit (BP) algorithm. The simulation experiment scheme of the decoding of the linear block code was designed. The simulation experiment results show that the linear block codes can be decoded well by the compressive sensing theory and the BP algorithm.

Using urea as the starting material, we prepared the lamellar structure of graphite carbon nitride (g-C3N4) by hightemperature pyrolysis method. The structures and morphologies of the samples were characterized by X-ray diffraction (XRD), X photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR). Rhodamine was used to test the photocatalytic and cyclic catalytic performances of the sample.

ZHU Ying, LI Hongliang, CAO Dianjun
Journal of Jilin University Science Edition. 2017, 55 (04):  1005-1011. 
Abstract ( 179 )   PDF (2826KB) ( 185 )  
Using the B3LYP method of density functional theory,  we investigated the chiral transition process of the methionine molecule under the cooperative a
ction of monoH2O at the level of 6-311+-G(2-df-). We drawed a complete chiral transition path reaction potential energy surface by finding structures of the extreme value points including the transition states and intermediates, and analyzed the geometric and electronic structure properties of extreme value points. The results show that the hydrogen atom on the chiral carbon atom of Smethionine molecule can transfer to the other side of the carbon atom via the 10O-19O atoms of carboxyl atoms as a bridge, and achieve the chiral transition of methionine molecule from Stype to Rtype. On this path there are four intermediates and five transition states. The maximum reaction energy barrier is 199.275 5 kJ/mol, which comes from the second transition state TS2-S-Met&1H2O2.

GAO Feng, JIANG Lisha, YAN Hongyan, YANG Xiaocui, WANG Zuocheng, TONG Hua
Journal of Jilin University Science Edition. 2017, 55 (04):  1012-1019. 
Abstract ( 190 )   PDF (3156KB) ( 149 )  
We studied the optical isomerism reaction of two kinds of the most stable configurations of methionine molecules based on amino group as proton transfer bridge by using the B3LYP method of density functional theory and the MP2 method of perturbation theory. The results show that there are two channels a and b in the optical isomerism reaction  of methionine molecules based on amino group as proton transfer bridge. The dominant reaction channel of
the configuration one is channel a, the ratedetermining step is the first elementary reaction, and the free energy barrier is 264.2 kJ/mol that is generated by the transition state of proton transfer from the chiral C to the amino N. The dominant reaction channel of the configuration two is the channel a, the ratedetermining step is the second elementary reaction, and the free energy barrier is 266.1 kJ/mol that is generated by the transition state of proton transfer from the chiral C to the amino N after carboxyl group isomerism. The reaction rate constants of the optical isomerism ratedetermining step of two configurations of methionine molecules are 3.04×10-34,1.41×10-34 s-1, respectively.

The orthogonal experiments were carried out with 3 single factors of time, temperature and ratio of material to liquid. The optimum conditions for the extraction of flavonoids from Pueraria lobata were m(material)∶V(liquid)=(1∶40)g/mL, 60 ℃ as exaction temperature and 3 h as exaction time. The crude extraction rate of P.lobata was 82%, and the highest extraction rate of flavonoids was 1804%. Using the model organism Caenorhabditis elegans as a model, we investigated the antioxidant effects of mass concentrations of 1,2,5 mg/mL of extraction of flavonoids on C.elegans, respectively. The results show that 1 mg/mL flavonoids extracts are fed to C.elegans and cultured 12 h at 35 ℃, the survival rate of C.elegans is significantly higher than that of the control group, i.e., flavonoids extract has obvious antioxidant effect.

Journal of Jilin University Science Edition. 2017, 55 (04):  1031-1036. 
Abstract ( 184 )   PDF (559KB) ( 158 )  
By potting experimental method, we studied effect of nanoTiO2 on the activity of Azotobacter in sandy soil, black soil and peaty soil. The results show that nanoTiO2 inhibit the activity of Azotobacter in different types of soil, and the order of inhibition is sandy soil>black soil>peaty soil. The inhibitory rate of Azotobacter increases with the increase of the dosage of nanoTiO2 at different doses (0.5,1.0,2.0 g/kg) in sandy soil and peaty soil. 2.0 g/kg nano TiO2 are added to sandy soil and peaty soil, and the inhibition ratio reaches the maximum at the 15th day, 25.73% and 12.76% respectively. After planting of alfalfa in three soils, the rhizosphere effect and root exudates can indirectly reduce the inhibitory effect of nanoTiO2 on Azotobacter. The difference is extremely significant between the planted group and the unplanted group (P<0.01) in the black soil and peaty soil, and the difference is significant between the planted group and the unplanted group (P<0.05) in the sandy soil.
