A combination weighting model based on iMOEA/D-DE Research Article

Mingtao DONG, Jianhua CHENG, Lin ZHAO,hbdmt@hrbeu.edu.cn,chengjianhua@hrbeu.edu.cn

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 4,   Pages 604-616 doi: 10.1631/FITEE.2000545

Abstract: This paper proposes a (CW) model based on i (i.‍e., improved multiobjective evolutionary algorithm based on decomposition with differential evolution) with the aim to accurately compute the weight of evaluation methods. Multi-expert weight considers only subjective weights, leading to poor objectivity. To overcome this shortcoming, a multiobjective optimization model of CW based on improved is proposed while considering the uncertainty of combination coefficients. An improved mutation operator is introduced to improve the convergence speed, and thus better optimization results are obtained. Meanwhile, an adaptive mutation constant and crossover probability constant with are proposed to improve the robustness of . Since the existing weight evaluation approaches cannot evaluate weights separately, a new weight evaluation approach based on is presented. Taking the evaluation method of integrated navigation systems as an example, certain experiments are carried out. It is proved that the proposed algorithm is effective and has excellent performance.

Measurement of bone alkaline phosphatase and relative study with osteosarcoma

YANG Zhiping, LI Jianmin, LI Xin, HUO Yanqing, SUN Guangzhi

Frontiers of Medicine 2007, Volume 1, Issue 1,   Pages 54-57 doi: 10.1007/s11684-007-0011-9

Abstract: The objective of this paper is to explore the value of bone alkaline phosphatase (BALP) for diagnosing osteosarcoma, evaluating the effect of the chemotherapy, judging the prognosis and supervising the relapse and metastasis. The immunoassay was used to check the BALP of the blood serum that was from 42 primary osteosarcoma patients. Alkaline phosphatase (ALP) in blood serum was checked with auto biochemistry equipment. The biopsy tissue and the lesion resected in operation were treated with pathology and histological response was counted. The patients were followed up from five months to 49 months with an average of 24.3 months. Eighteen cases relapsed and transferred, among which, 16 of them were dead, and others were survival to the end of the follow-up. BALP was more sensitive than ALP in diagnosing osteosarcoma ( = 0.015). Fifteen cases decreased to normal value in ALP after preoperative chemotherapy, and 34 cases decreased in BALP. Both ALP and BALP in all cases decreased to normal value in postoperative. There was significant difference in positive correlation between the decrease of BALP and the increase of histological response ( = 0.001, = 0.642). In the followup, there was significant difference in BALP between the group of relapse and transfer and the group of free disease survival ( = 0.000). As a check marker in blood serum, BALP, reflecting the process of ossification, has a higher sensitivity than ALP. It has applied value in the diagnosis of osteosarcoma, reflection of the effect of chemotherapy and forecast the prognosis.
