| 1 | 基于温度的天气衍生品指数定价:以埃塞俄比亚巴赫达尔为例(英文)显示文摘本文提出了一个基于温度的导数来计算温度指数的日平均温度随机模型,该模型提出了一个季节性均值及其波动率的计算方法,使用均值回归的Ornstein-Uhlenbeck过程来刻画日平均温度的变化。本文还采用连续的三阶自回归过程来模拟去除趋势和季节性影响后的温度演变过程,模型的模拟结果与从埃塞俄比亚国家气象厅获得的2005年1月1日至2015年12月31日11年间埃塞俄比亚Bahir Dar记录的数据非常吻合。验证后的近似公式很容易根据热日和冷日(heating degree days (HDD) and cooling degree days (CDD))等典型温度指数推导期货价格,也给出了数值例子来说明该方法的准确性。结果表明,本文提出的模型比其他模型能更好地预测CDD指数。 | Tesfahun BERHANE Aemiro SHIBABAW Gurju AWGICHEW | 2019 | Journal of Resources and Ecology2019，10，4： | 4 |
| 2 | International validation of the Chinese University Prognostic Index for staging of hepatocellular carcinoma: a joint United Kingdom and Hong Kong study显示文摘The outcome of hepatocellular carcinoma(HCC) patients significantly differs between western and eastern population centers. Our group previously developed and validated the Chinese University Prognostic Index(CUPI) for the prognostication of HCC among the Asian HCC patient population. In the current study, we aimed to validate the CUPI using an international cohort of patients with HCC and to compare the CUPI to two widely used staging systems, the Barcelona Clinic Liver Cancer(BCLC) classification and the Cancer of the Liver Italian Program(CLIP). To accomplish this goal, two cohorts of patients were enrolled in the United Kingdom(UK; n = 567; 2006-2011) and Hong Kong(HK; n = 517; 2007-2012). The baseline clinical data were recorded. The performances of the CUPI, BCLC, and CLIP were compared in terms of a concordance index(C-index) and were evaluated in subgroups of patients according to treatment intent. The results revealed that the median follow-up durations of the UK and HK cohorts were 27.9 and 29.8 months, respectively. The median overall survival of the UK and HK cohorts were 22.9 and 8.6 months, respectively. The CUPI stratified the patients in both cohorts into three risk subgroups corresponding to distinct outcomes. The median overall survival of the CUPI low-, intermediate-, and high-risk subgroups were 3.15, 1.24, and 0.29 years, respectively, in the UK cohort and were 2.07, 0.32, and 0.10 years, respectively, in the HK cohort. For the patients who underwent curative treatment, the prognostic performance did not differ between the three staging systems, and all were suboptimal. For those who underwent palliative treatment, the CUPI displayed the highest C-index, indicating that this staging system was the most informative for both cohorts. In conclusion, the CUPI is applicable to both western and eastern HCC patient populations. The performances of the three staging systems differed according to treatment intent, and the CUPI was demonstrated to be optimal for those undergoing palliative treatment. A more precise staging system for early-stage disease patients is required. | Stephen L.Chan Philip J.Johnson Frankie Mo Sarah Berhane Mabel Teng Anthony W.H.Chan Ming C.Poon Paul B.S.Lai Simon Yu Anthony T.C.Chan Winnie Yeo | 2014 | Chinese Journal of Cancer2014，33，10： | 4 |
