Preprocessing of Separating Leukocytes Based on Setting Parameters of Lightness Transformation  [PDF]
Jianyong Cai, Lili Luo, Rongtai Cai, Lijin Lin, Juan Cai
Journal of Signal and Information Processing (JSIP) , 2013, DOI: 10.4236/jsip.2013.44051
Abstract: This paper proposed a new algorithm to separate leukocytes from cytological image by setting parameters of lightness transformation based on the RGB color space, which can make the targets’ color in different areas. In our procedure, an operator is employed in using color features. According to their histogram distribution of hue component in HSL color space after enhancing the contrast of image in RGB color space, the threshold of segmentation between leukocyte and erythrocyte could be achieved well. Especially, this algorithm is more efficient than monochrome for leukocyte segmentation, and the results of experiments show that it provides a good tool for cytological image, which can increase accuracy of segmentation of leukocyte.
Object-Guided Ant Colony Optimization Algorithm with Enhanced Memory for Traveling Salesman Problem
Lijin Wang,Rongying Cai,Lin Jing,Hui Zhang
Research Journal of Applied Sciences, Engineering and Technology , 2012,
Abstract: In this study, we presents an object-guided ACO algorithm which is consisted of ants with enhanced memory. In the process of solution construction, each ant stores a complete solution in its enhanced memory. Each time ant selects a solution component probabilistically, it will calculate the difference between current solution and the new solution after adding the selected component and then Metropolis accepting rule, which has been used in simulated annealing algorithm successfully, is used to decide whether to accept the component or discard it. The simulation results, which were carried on benchmark traveling salesman problems, show that the improvement of individual intelligence can improve the performance of ACO algorithm remarkably.

Weiyu Chen, Lijin Zhang
American Journal of Industrial and Business Management (AJIBM) , 2016, DOI: 10.4236/ajibm.2016.68081
Abstract: With the coordinated progress in advancing comprehensively deepening reform and the implementation for fully advancing the law-based governance of the country, the process of the modernization of national governance is comprehensively advancing, and great change has occurred in economic, social, political and some other fields. The development of national audit is facing new opportunities and challenges. In order to adapt to the new changes in the governance of the country, the national audit should break its restrictions about its theoretical framework, range, key, and methods, and make positive change and innovation development towards the direction of policy following audit, high pressure anti-corruption audit, and information-based audit.
The base-scale entropy analysis of short-term heart rate variability signal
科学通报(英文版) , 2005,
Abstract: The complexity of heart rate variability (HRV) signal can reflect physiological functions and healthy status of heart system. Detecting complexity of the short-term HRV signal has an important practical meaning. We introduce the base-scale entropy method to analyze the complexity of time series. The advantages of our method are its simplicity, extremely fast calculation for very short data and anti-noise characteristic. For the well-known chaotic dynamical system- logistic map, it is shown that our complexity behaves similarly to Lyapunov exponents, and is especially effective in the presence of random Gaussian noise. This paper addresses the use of base-scale entropy method to 3 low-dimensional nonlinear deterministic systems. At last, we apply this idea to short-term HRV signal, and the result shows the method could robustly identify patterns generated from healthy and pathologic states, as well as aging. The base-scale entropy can provide convenience in practically applications.
A Pragmatic Account of Anaphora: The Cases of the Bare Reflexive in Chinese*
Lijin Liu
Journal of Language Teaching and Research , 2010, DOI: 10.4304/jltr.1.6.796-806
Abstract: Most, if not all, of the existing research on anaphoric constructions containing the bare reflexive ‘ziji’ in Chinese has been done on a formalist basis and some found in the literature has as it were not given a cogent explanation. The present article, largely based on some discourse and/or pragmatic principles and following a close examination of data drawn from various texts, describes and analyzes its anaphoric uses in two domains: the local and the long-range. The findings suggest that in either case, this bare or simplex reflexive occurs, anaphorically, much more frequently than an alternate complex reflexive or a plain pronoun, which results from the fact that it serves a twofold role, as an alternative to a complex reflexive, on one hand, to minimalize communicative reference and to a pronoun, on the other, to save time for discourse understanding. Such anaphora facts are regulated by a neo-Gricean-like pragmatic principle re the uses of third-person pronouns in Chinese: (a) where the grammar permits the occurrence of both a bare and a complex reflexive, the speaker intending locally bound anaphora tends to use the bare to produce the minimal linguistic information enough to achieve the communicational ends, unless motivated otherwise; (b) where the context permits the occurrence of both a bare reflexive and a pronoun, the speaker intending long-range coreference tends to use the bare reflexive to ease discourse interpretation, unless prevented doing so by other considerations.
Effective Computation of Stochastic Protein Kinetic Equation by Reducing Stiffness via Variable Transformation
Lijin Wang
Mathematics , 2014,
Abstract: The stochastic protein kinetic equations can be stiff for certain parameters, which makes their numerical simulation rely on very small time step sizes, resulting in large computational cost and accumulated round-off errors. For such situation, we provide a method of reducing stiffness of the stochastic protein kinetic equation by means of a kind of variable transformation. Theoretical and numerical analysis show effectiveness of this method. Its generalization to a more general class of stochastic differential equation models is also discussed.

Cardiovascular Diabetology , 2007, DOI: 10.1186/1475-2840-6-16
Abstract: Diabetic porcine model was created with an intravenous administration of a single dose of streptozotocin in 15 Chinese Guizhou minipigs (diabetic group); each of them received 2 SES (Firebird, Microport Co, China) implanted into 2 separated major epicardial coronary arteries. Fifteen non-diabetic minipigs with SES implantation served as controls (control group). At 6 months, the degree of neointimal hyperplasia was determined by repeat coronary angiography, intravascular ultrasound (IVUS) and histological examination. Tumor necrosis factor (TNF)-α protein level in the aortic intima was evaluated by Western blotting, and TNF-α, interleukin (IL)-1β and IL-6 mRNA levels were assayed by reverse transcription and polymerase chain reaction.The distribution of stented vessels, diameter of reference vessels, and post-procedural minimal lumen diameter were comparable between the two groups. At 6-month follow-up, the degree of in-stent restenosis (40.4 ± 24.0% vs. 20.2 ± 17.7%, p < 0.05), late lumen loss (0.33 ± 0.19 mm vs. 0.10 ± 0.09 mm, p < 0.001) by quantitative angiography, percentage of intimal hyperplasia in the stented area (26.7 ± 19.2% vs. 7.3 ± 6.1%, p < 0.001) by IVUS, and neointimal area (1.59 ± 0.76 mm2 vs. 0.41 ± 0.18 mm2, p < 0.05) by histological examination were significantly exacerbated in the diabetic group than those in the controls. Significant increases in TNF-α protein and TNF-α, IL-1β and IL-6 mRNA levels were observed in aortic intima in the diabetic group.Neointimal hyperplasia persisted at least up to 6 months after SES implantation in diabetic porcine, which may be partly related to an exaggerated inflammatory response within the blood vessel wall. Our results provide theoretical support for potential direct beneficial effects of anti-diabetic and anti-inflammation medications in reducing the risk of restenosis after stenting.Diabetes mellitus has now been a worldwide epidemic and is growing as a public problem. Coronary artery disease is highly p

Photophysics, photochemistry and photobiology of hypocrellin photosensitizers
Lijin Jiang,Yuying He
Chinese Science Bulletin , 2001, DOI: 10.1007/BF03183199
Abstract: Hypocrellins are novel photosensitizers from China, which are demonstrated to have significant antitumor and anti-virus activity and to be potential photodynamic therapy (PDT) agents. As compared with hematoporphyrin, the only approved photosensitizer, hypocrellins have several advantages, such as easy preparation and easy purification, high triplet quantum yield, high singlet-oxygen quantum yield, high phototoxicity but low dark toxicity, and rapid clearance from normal issues. This article reviews briefly the photophysics, photochemistry and photobiology of hypocrellins on the basis of the domestic and international research results.
