| 1 | IMPROVED GENETIC ALGORITHM TO OPTIMAL PORTFOLIO WITH RISK CONTROL显示文摘A modified model of optimal investment port folio in a random market with risk constraints is presented. An improved genetic algorithm (GA) is proposed to solve this nonlinear optimal problem. The numerical simulation of a large-scale investment combination for Shanghai stock market shows that GA has the advantage of faster convergence and wider adaptability than traditional optimization algorithm. This result alsodemonstrates that the improved GA performs better than the basic GA. | Ye Zhongxing Zhang Yijun(Dept. of Applied Mathematics) (Application Solution & Technolodge Inc., Shanghai) | 1996 | Journal of Shanghai Jiaotong university(Science)1996，1，2： | 2 |

| 7 | Integrated circulating tumor DNA and T cell repertoire predict radiotherapeutic response and outcome in non-small cell lung cancer patients with brain metastasis显示文摘Dear editor,The scarcity of routinemetastatic biopsies or resection limits the finding of biomarkers of diagnosis and prognosis in patients with brain metastases.Derived from necrosis,apoptosis,and secretion of tumor cells,circulating tumor DNA(ctDNA)is widely distributed in various body fluids,including peripheral blood and cerebrospinal fluid(CSF),as an alternative biomarker for tumor-associated analysis[1].Fortunately,genomic alterations of blood ctDNA and CSF ctDNA have been proven as prognostic markers in non-small cell lung cancer(NSCLC)patients with brain metastasis[2,3]. | Ling Peng Yawen Bin Peng Ding Lingjuan Chen Hao Zeng Zelong Xu Liyan Ji Xuan Gao Pian Liu Ye Wang Sheng Zhang Zhongxing Liao Xuefeng Xia Ruiguang Zhang Fan Tong Xiaorong Dong | 2023 | Cancer Communications2023，43，5： | 0 |
| 8 | Replacement of Flake Graphite in Aluminacarbon Refractories by Hexagonal Boron Nitride显示文摘Three kinds of composite alumina refractories were prepared with tabular alumina( 3- 1 and 1- 0 mm) as aggregates, tabular alumina powder, α-Al2O3 micropowder,and Si powder as matrix,adding 3 mass%hexagonal boron nitride( h-BN), 3 mass% flake graphite and 10 mass% flake graphite, respectively.Cold physical properties,hot modulus of rupture,oxidation resistance,thermal shock resistance and slag corrosion resistance of the specimens were compared. The results show that:( 1) physical properties and hot modulus of rupture of Al2O3- h-BN refractories are slightly different from those of low carbon Al2O3- C refractories,but better than those of traditional Al2O3- C refractories with 10 mass% graphite;( 2) Al2O3- h-BN refractories have better thermal shock resistance and oxidation resistance than the carbon containing refractories,while similar slag resistance with low carbon Al2O3- C refractories;( 3) h-BN can replace flake graphite as a starting material for the preparation of composite alumina refractories,considering the overall properties of the material. | LIANG Feng XUE Zhengliang ZHAO Lei FANG Wei YE Linfeng LEI Zhongxing | 2014 | China's Refractories2014，23，4： | 0 |
