| 1 | Non-equal-interval direct optimizing Verhulst model that x(n) be taken as initial value and its application显示文摘To overcome the deficiencies of the existing Verhulst GM(1,1) model, based on the existing grey theory, a non-equal-interval direct optimum Verhulst GM(1,1) model is built which chooses a modified n-th component x(n) of X(0) as the starting condition of the grey differential model. It optimizes a modified β value and the background value, and takes two times fitting optimization. The new model extends equal intervals to non-equal-intervals and is suitable for general data modelling and estimating parameters of the direct Verhulst GM(1,1). The new model does not need to pre-process the primitive data, nor accumulate generating operation (AGO) and inverse accumulated generating operation (IAGO). It is not only suitable for equal interval data modelling, but also for non-equal interval data modelling. As the new information is fully used and two times fitting optimization is taken, the fitting accuracy is the highest in all existing models. The example shows that the new model is simple and practical. The new model is worth expanding on and applying in data processing or on-line monitoring for tests, social sciences and other engineering sciences. | Luo, Youxin Chen, Mianyun Che, Xiaoyi He, Zheming | 2008 | Journal of Southeast University(English Edition)2008，24，S1： | 2 |

| 4 | Preparation of hollow-fiber nanofiltration membranes of high performance for effective removal of PFOA and high resistance to BSA fouling显示文摘Nanofiltration(NF)process has become one of the most promising technologies to remove micro-organic combined water pollution.Developing a NF membrane material with efficient separation for perfluorooctanoic acid(PFOA)combined pollution is highly desired,this manuscript targets this unmet need specifically.In this work,hydrophilic SiO_(2)nanoparticles with various contents blended with carboxylic multiwalled carbon nanotube were used to modify poly(m-phenylene isophthal amide)(SiO_(2)/CMWCNT/PMIA)hollow fiber NF membrane.The modified membrane with 0.1 wt%SiO_(2)doping exhibits way better fouling resistance with irreversible fouling ratio decreased dramatically from 18.7%to 2.3%,and the recovery rate of water flux increases significantly from 81.2%to 97.7%.The separation experiment results had confirmed that the modified membrane could improve the rejection from 97.2%to 98.6%for perfluorooctanoic acid(PFOA)and its combined pollution with bovine serum albumin(BSA).It is clear that this reported SiO_(2)/CMWCNT/PMIA hollow fiber NF membrane potentially could be applied in water treatment.This research also provides a theoretical basis for efficiently removal of PFOA and its combined pollution by NF membrane. | Wenjing Tang Yunyi Meng Bin Yang Dongyu He Yan Li Bojun Li Zheming Shi Changwei Zhao | 2022 | Journal of Environmental Sciences2022，34，12： | 0 |
| 5 | Phytoestrogen-derived multifunctional ligands for targeted therapy of breast cancer显示文摘Nano-targeted delivery systems have been widely used for breast tumor drug delivery.Estrogen receptors are considered to be significant drug delivery target receptors due to their overexpression in a variety of tumor cells.However,targeted ligands have a significant impact on the safety and effectiveness of active delivery systems,limiting the clinical transformation of nanoparticles.Phytoestrogens have shown good biosafety characteristics and some affinity with the estrogen receptor.In the present study,molecular docking was used to select tanshinone IIA(Tan IIA)among phytoestrogens as a target ligand to be used in nanodelivery systems with somemodifications.Modified Tan IIA(Tan-NH2)showed a good biosafety profile and demonstrated tumor-targeting,anti-tumor and anti-tumor metastasis effects.Moreover,the ligand was utilized with the anti-tumor drug Dox-loaded mesoporous silica nanoparticles via chemical modification to generate a nanocomposite Tan-Dox-MSN.Tan-Dox-MSN had a uniform particle size,good dispersibility and high drug loading capacity.Validation experiments in vivo and in vitro showed that it also had a better targeting ability,anti-tumor effect and lower toxicity in normal organs.These results supported the idea that phytoestrogens with high affinity for the estrogen receptor could improve the therapeutic efficacy of nano-targeted delivery systems in breast tumors. | Ying Zhang Hao Pan Changxiang Yu Rui Liu Bin Xing Bei Jia Jiachen He Xintao Jia Xiaojiao Feng Qingqing Zhang Wenli Dang Zheming Hu Xiuping Deng Pan Guo Zhidong Liu Weisan Pan | 2023 | Asian Journal of Pharmaceutical Sciences2023，18，4： | 0 |
