Comparative Study on the Present Situation in the Development of the Chinese Long River Delta Women Football Team  [PDF]
Hongxia Zhang
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.37B012
Abstract:

Chinese Long River Delta has three Women Football Teams. The present situation of Chinese Long River Delta Women Football Team attending the 2005 spring training was investigated and studied through questionnaires,observations and visiting. The present management system,fund sources, basic conditions of the coaches and players in the Chinese Long River Delta Women Football Teams are clear. It was found that at present the management system of Shanghai and Jiangsu Women football teams are come up to the professional management system. But Zhejiang Women football hasn’t been very well popularized. An orderly system of succession hasn’t been formed. The unstable coach population requires to be trained and to raise their level. And their manage policy and measures is insufficient compare with Shanghai and Jiangsu women football team.

An Optimal Inventory Control Model for a Supply Chain with Shortage Constraints
Yinkuan Gu,Hongxia Zhang
Journal of Computers , 2011, DOI: 10.4304/jcp.6.9.1862-1867
Abstract: The article studies, with the level constraints in short supply, the inventory decision model of the minimum total annual cost of the supply chain which, composed of a single supplier and multiple buyers, involving supplier’s lead time as a decision variable, replacing the cost of shortages with the level in short supply, and has solved the difficult problem in the practice.
Studying dynamic process of photosensitization by ESR method
Hongyu Zhang,Hongxia Zhao,Zhiyi Zhang
Science China Life Sciences , 1997, DOI: 10.1007/BF02881728
Abstract: By kinetic methods, functional relation of TAN radical, produced in the process of TEMPONE trapping1O2, vs. time during photosensitization was established. Accordingly relative rate constants of generating all kinds of active intermediates through types I and II mechanism of photosensitization can be calculated. Using the formula and experimental results, the relative rate constants of generating1O2, and of three kinds of perylenequinone photosensitizer: HA, HB and CP in DMF-H2O and DMSO-H2O system were calculated, and then the structure-activity relationship of perylenequinone photosensitizer and the relation between photosensitivity and solvent was studied.

Abstract:

In this paper, it is proved that every nonlinear Jordan triple derivation on triangular algebra is an additive derivation.

Raman spectroscopic study of DNA photodamage sensitized by hypocrellin B and 5-brominated-hypocrellin B
Hongxia Zhao,Yiming Xu,Zhiyi Zhang
Chinese Science Bulletin , 1998, DOI: 10.1007/BF02883087
Abstract: Hypocrellin B (HB) is a highly effective photosensitizer. One of its derivatives, 5-brominated-hypocrellin B (5-Br-HB) has better photosensitive characterlstics than it. Using Raman spectroscopy, the microcosmic photodamage to DNA sensitized by HB and 5-Br-HB was studied at molecular level. The results showed that when HB and 5-Br-HB were added to the solution of DNA and irradiated, the characteristic Raman frequencies and intensities of DNA changed to various degrees. The photodamage occurred on the whole DNA molecule, including phosphate backbone, deoxyribose and four bases. Not only the conformation but also the configuration of DNA was photodamaged: breakage of some H-bonds, disappearance of B-form conformation, scission of double or single strand and serious damage of four bases. The damage to A-T pairs was stronger than that to C-G pairs and DNA became polynucleotides finally. The 5-Br-HB-photosensitized damage to DNA was stronger than HB, which suggested the better photosensitive characteristics of 5-Br-HB in bioactive environment. The molecular mechanisms of photodamage to DNA sensitized by 5-Br-HB and HB were also elucidated.
The ecological sequence of Hipparion fauna in the middle reaches of the Yellow River during Neogene
Yunxiang Zhang,Leping Yue,Hongxia Cao
Chinese Science Bulletin , 2002, DOI: 10.1360/02tb9016
Abstract: The faunal ecological type and sequence in the Tertiary red clay indicate that Hipparion fauna during the period 7.4–6.1 Ma in the middle reaches of the Yellow River is composed mainly of dorcadoides and mixed types. This represents semiarid veld environment with small fluctuation. The fossil assemblages characterized by the abundance of gaudryi types and even the occurrence of some Hominoid and Chalicotherium indicate an obviously warm and humi period since 5.3 Ma. The fossil assemblages during 3.4 Ma show the typical steppe fauna representing dry climate. It is indicated by the changes of ecological sequence that the climatic conditions in Pliocene are drier than that in late Miocene. The clay-skin content of red clay, which has a synchronous change with faunal features, is a rather good replacing palaeoclimatic index.

Hongxia Zhang,Donghui Qu,Jing Ma
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812037981
Abstract: In the title molecule, C22H17ClN2O5, the nitro-substituted benzene ring makes a dihedral angle of 79.22 (1)° with the benzoyl ring and 53.03 (1)° with the chloro-substituted benzene ring. An intramolecular C—H...O hydrogen bond occurs. The crystal structure features weak C—H...Cl and C—H...O interactions.
Study of An Improved Genetic Algorithm Based on Fixed Point theory and hJ1 triangulation in Euclidean Space
Jingjun Zhang,Hongxia Wang,Ruizhen Gao
Journal of Computers , 2011, DOI: 10.4304/jcp.6.10.2173-2179
Abstract: Aiming at the convergence precision defects of standard genetic algorithm, the fixed point theory is introduced into the genetic algorithms. The population of individual is regarded as the triangulation of the point. Hence the vertex label information of the individual simplex would guide the algorithm to the optimization researching and convergence judgment which could be calculated with the hJ1 triangulation and integer label. When the loading simplexes of individuals are transferred into the completely labeled simplexes, the algorithm will be terminated and the global optimal solution will be got. Finally, some functions are used to demonstrate the effectiveness and strong stability of the algorithm through solving the minimum points distinguished by using the Hessian Matrix and then compared with the standard genetic algorithms and J1 triangulation.
Compressed Sensing Based on the Single Layer Wavelet Transform for Image Fusion  [PDF]
Guohui Yang, Wude Xu, Bo Zheng, Fanglan Ma, Xuhui Yang, Hongwei Ma, Hongxia Zhang, Genliang Han
Journal of Computer and Communications (JCC) , 2016, DOI: 10.4236/jcc.2016.415010
Abstract:
In this paper, a new method of combination single layer wavelet transform and compressive sensing is proposed for image fusion. In which only measured the high-pass wavelet coefficients of the image but preserved the low-pass wavelet coefficient. Then, fuse the low-pass wavelet coefficients and the measurements of high-pass wavelet coefficient with different schemes. For the reconstruction, by using the minimization of total variation algorithm (TV), high-pass wavelet coefficients could be recovered by the fused measurements. Finally, the fused image could be reconstructed by the inverse wavelet transform. The experiments show the proposed method provides promising fusion performance with a low computational complexity.
