纤维化影响着数以百万计的心脏病患者，但目前抗纤维化疗法旨在限制纤维化进展，而并非在形成初始就对其进行重塑。为此，已有研究报道特异性消除活化成纤维细胞的嵌合抗原受体 (chimeric antigen receptor, CAR) T细胞可以作为心力衰竭的治疗方法【1】，但问题就在于CAR T细胞在体内的持久生命力。成纤维细胞活化是许多组织中正常伤口愈合过程的一部分，而持久的抗纤维化CAR T 细胞...

基于CAR-DEA方法的环境效率评价研究
数据包络分析 不期望产出 保证域 CAR-DEA

2012/8/3
现有环境效率评价的DEA方法没有考虑多维偏好约束问题，即不同决策单元对不同期望产出和不期望产出的偏好不同. 以地区为例，不同地区对GDP、废水和废气赋予的权重偏好各不相同. 在这种情况下，由于各决策单元的偏好约束不同，形成多维偏好约束集，在传统DEA模型中容易出现无可行解现象. 针对这一问题，基于CAR-DEA方法，结合保证域理论，提出一种解决多维偏好约束集问题的环境效率评价模型. 采用中国工业系...

基于SVR和CAR的多维时间序列分析及其在生态学中的应用
多维时间序列 支持向量回归

2007/12/10
摘要 基于支持向量回归（SVR）并融合带受控项的自回归模型（CAR），建立了一种既反映样本集动态特征又体现环境因子影响的非线性多维时间序列分析预测方法（SVR-CAR）。用一步预测法对两个生态学样本集的预测结果表明，SVR-CAR在所有参比模型中预测精度最高，并具结构风险最小、非线性、避免过拟合、泛化推广能力优异等诸多优点。SVR-CAR在生态学、农业科学、经济学等多维时间序列预测领域有较广泛的应...
