The growth dynamics of tumor subject to both immune surveillance and external therapy intervention
YuanZhi Shao,WeiRong Zhong,FengHua Wang,ZhenHui He,ZhongJun Xia
Chinese Science Bulletin , 2007, DOI: 10.1007/s11434-007-0234-9
Abstract: Considering the growth of tumor cells modeled by an enzyme dynamic process under an immune surveillance, we studied in anti-tumor immunotherapy the single-variable growth dynamics of tumor cells subject to a multiplicative noise and an external therapy intervention simultaneously. The law of tumor growth of the above anti-tumor immunotherapy model was revealed through numerical simulations to the relevant stochastic dynamic differential equation. Two simulative parameters of therapy, i.e., therapy intensity and therapy duty-cycle, were introduced to characterize a treatment process similar to a tumor clinic therapy. There exists a critical therapy boundary which, in an exponent-decaying form, divides the parameter region of therapy into an invalid and a valid treatment zone, respectively. A greater critical therapy duty-cycle is necessary to achieve a valid treatment for a lower therapy intensity while the critical therapy intensity decreases accordingly with an enhancing immunity. A primary clinic observation of the patients with the typical non-hodgekin’s lymphoma was carried out, and there appears a basic agreement between clinic observations and dynamic simulations.
Research on the Relationship between External Compensation Gap of Executives and Enterprise Innovation  [PDF]
Yangyang Gu, Zhongjun Yang
Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.68022
Abstract: How to use the pay contract to encourage executives to implement innovation activities has become an important issue to be solved by the theoretical and practical circles. Based on the data of Shanghai and Shenzhen A-share listed companies from 2006 to 2015, this paper examines the impact of external compensation gap on corporate innovation, and further discusses the contextual effects of executive talent and property rights. The study finds that the external compensation gap of executives has a positive effect on enterprise innovation. Moreover, the higher talent executives possess, the more obvious the external compensation gap will promote the innovation of enterprises. In addition, compared with state-owned enterprises, the external compensation gap of non-state-owned enterprise executives has a more significant effect on corporate innovation. This paper not only expands the economic consequences of the external compensation gap, but also provides inspiration for companies to adjust the compensation structure and encourage executives to promote enterprise innovation.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808016139
Abstract: In the molecule of the title compound, [Sn(C6H5)2(C6H5N2O2)2], two O and one N atoms from the two 5-methylpyrazine-2-carboxylate ligands and one C atom of a phenyl group form a distorted square-planar arrangement in the equatorial plane around the Sn atom, while the distorted octahedral coordination is completed by an N atom of one of the 5-methylpyrazine-2-carboxylate ligands and a C atom of the other phenyl group in the axial positions. In the crystal structure, intermolecular C—H...O hydrogen bonds link the molecules into centrosymmetric dimers.
Research on the Website Keywords Seeding System Based on SEO

Journal of Computers , 2011, DOI: 10.4304/jcp.6.1.75-82
Abstract: Website Information Island leads to information partition between sites and customers, and holds back the improvement of website popularity. To solve this problem, the paper proposes website keywords seeding system based on internal and external SEO, and provides data structure, operation process and key algorithm inside model; According to external customers' high-frequency search terms and internal customers' demand, this model uses multi-dimensional vector overlay space to match and extract information required by customers, has internal website optimized automatically and issues keywords. Theoretical analysis and experimental results both show that, the model has a high feedback speed for demand, which can improve sites' customer satisfaction and search rankings effectively.

Abstract: The clinicopathological features of 83 Chinese patients with PGL were retrospectively reviewed. Staging was performed according to the Lugano staging system for gastrointestinal non-Hodgkin's lymphoma.The predominant pathologic subtype among Chinese patients with PGL in our study was diffuse large B cell lymphoma (DLBCL), followed by mucosa-associated lymphoid tissue (MALT) lymphoma. Among the 57 patients with gastric DLBCL, 20 patients (35.1%) were classified as the germinal center B cell-like (GCB) subtype and 37 patients (64.9%) as the non-GCB subtype. The 83 patients had a five-year overall survival (OS) and event-free survival (EFS) of 52% and 59%, respectively. Cox regression analysis showed that stage-modified international prognostic index (IPI) and performance status (PS) were independent predictors of survival. In the 67 B-cell lymphoma patients who received chemotherapy, 36 patients treated with rituximab (at least 3 cycles) had a mean OS of 72 months (95% CI 62-81) versus 62 months (95% CI 47-76) for patients without rituximab treatment (P = 0.021).The proportion of Chinese gastric DLBCL cases with non-GCB subtype was higher than the GCB subtype. Stage-modified IPI and PS were effective prognostic factors in Chinese patients with PGL. Our data suggested that primary gastric B-cell lymphoma might have an improved outcome with rituximab in addition to chemotherapy. More studies are necessary, preferentially large prospective randomized clinical trials to obtain more information on the impact of the rituximab in the primary gastric B-cell lymphoma.Primary gastric lymphoma (PGL) originates in the stomach, with or without perigastric and/or abdominal lymph node involvement [1]. PGL is an uncommon tumor, accounting for less than 15% of gastric malignancies and about 2% of all lymphomas [2]. However, PGL is the most common extranodal lymphoma, representing 30%-40% of all extranodal lymphomas and 60%-75% of all gastrointestinal lymphomas [3-6]. The incidence of
Modeling and Control of pH in Pulp and Paper Wastewater Treatment Process  [PDF]
Jiayu KANG, Mengxiao WANG, Zhongjun XIAO
Journal of Water Resource and Protection (JWARP) , 2009, DOI: 10.4236/jwarp.2009.12016
Abstract: Pulp and paper industry is responsible for large discharge of highly polluted effluents, which often be treated by biological treatment process. For biological treatment system, pH is an important environmental factor that can influence the activity of microorganisms. In general, the optimal pH for aerobic processes is around neutral pH (7_7.8) and for the anaerobic process is between 6.8_7.2. The control of pH is a difficult link in the biological treatment system due to its nonlinearity and large time-delay. Aiming at the difficult point in the pH control of the biological wastewater treatment system, a mathematical model of pH control is estab-lished in the essay. On this basis, a traditional PID control and a cascade control are adopted to carry out simulation and comparison with MATLAB. The results show that the cascade control has better comprehen-sive effect in terms of response speed, stability and disturbance resistance.
