| 1 | Power hardware in the loop validation of fault ride through of VSC HVDC connected offshore wind power plants显示文摘This paper presents the power hardware in the loop(PHIL)validation of a feed forward DC voltage control scheme for the fault ride through(FRT)of voltage source converter(VSC)high voltage DC(HVDC)connected offshore wind power plants(WPPs).In the proposed FRT scheme,the WPP collector network AC voltage is actively controlled by considering both the DC voltage error and the AC current from the WPP AC collector system which ensures fast and robust FRT of the VSC HVDC connected offshore WPPs.The PHIL tests were carried out in order to verify the efficacy of the proposed feed forward DC voltage control scheme for enhancing the FRT capability of the VSC HVDC connected WPPs.The PHIL test results have demonstrated the proper control coordination between the offshore WPP and the WPP side VSC and the efficient FRT of the VSC HVDC connected WPPs. | Ranjan SHARMA Qiuwei WU Seung Tae CHA Kim H.JENSEN Tonny W.RASMUSSEN JacobØSTEGAARD | 2014 | Journal of Modern Power Systems and Clean Energy2014，2，1： | 26 |
| 2 | Adjuvant chemotherapy for intrahepatic cholangiocarcinoma: approaching clinical practice consensus?显示文摘Background:Intrahepatic cholangiocarcinoma(ICC)is rare with limited evidence-based guidelines.This retrospective study evaluates the use of chemotherapy in patients with resected ICC.Methods:The Surveillance Epidemiology and End Results(SEER)program database was used to identify patients with resected ICC.Patients were stratified by date of diagnosis(2000-2004,2005-2009,2010-2014),T,and N stage.Multivariable logistic regression models identified predictors of chemotherapy use.Kaplan-Meier and Cox proportional hazard models were used to identify survival trends.Results:One thousand and two hundred twenty-three patients met inclusion criteria.Chemotherapy utilization increased over time(33%to 41%,P≤0.05).Chemotherapy use increased in lymph node(LN)positive patients[32%to 60%in 2010-2014;(P≤0.05)and T3/T4 disease(40%to 60%in 2010-2014;P≤0.01)],but not in patients with LN negative or T1/T2 disease.LN positivity was associated with utilization of chemotherapy in 2005-2009 and 2010-2014.Overall survival increased from 32 to 41 months(P≤0.05).In LN positive patients,chemotherapy was associated with a decreased hazard ratio of death(P≤0.05)and T3/T4 disease was associated with an increased hazard ratio of death(P≤0.05).Conclusions:Adjuvant chemotherapy use in ICC has increased.More LN positive or patients with T3/T4 tumors are receiving chemotherapy,which may explain the improvement in overall survival. | Ariella M.Altman Scott Kizy Schelomo Marmor Jane Y.C.Hui Todd M.Tuttle Eric H.Jensen Jason W.Denbo | 2020 | Hepatobiliary Surgery and Nutrition2020，9，5： | 10 |

| 11 | 激励与公共部门外包合同的效率显示文摘在工业化国家,将传统上由公共部门提供的服务外包已是非常普遍的现象。尽管这种外包非常盛行,但在学术研究上关于外包带来的预期成本节约程度以及成本节约的来源等问题上,仍没有一致的结论。本文讨论了关于支持和反对外包的观点并对与外包是否会产生成本节约以及这种节约能否持续的相关实证证据进行了验证;此外,还论证了'收入分配假说'和'质量下降假说'的相关证据。这两个理论认为外包主要是通过降低工资和服务质量来减少政府的支出。最后,我们考虑了合同设计对外包结果的影响。激励的强度在经济学中是一个重要的研究主题,最近的研究工作表明了高强度激励对于很多公共服务来说可能是次优的,因为高强度激励挤出了内在动机,特别是在那些具有高度主动性的代理人的情形中更是如此。我们最后讨论了关于这个观点的政策含义。 | Paul H.Jensen Robin E.Stonecash 叶婷婷 谢贞发 | 2010 | 经济资料译丛2010，，4： | 1 |
| 12 | Neurological consequences of human calmodulin mutations显示文摘When calcium ions enter the cytosol,it is a stimulatory signal for cellular events.The calcium sensor calmodulin picks up the change in calcium concentration and relays this information to its more than 300 downstream interaction partners.In this way,calmodulin affects cellular processes such as fertilization,muscle contraction,neuronal firing,and apoptosis.That is,calmodulin is involved in(nearly)everything!The significance of calmodulin is emphasized by the fact that we all carry three different genes(CALM1,2,3)on different chromosomes that encode the exact same calmodulin protein,and these are all expressed in all cell types.Moreover,throughout vertebrate evolution,the protein sequence has remained completely unchanged. | Helene H.Jensen Anders Olsen | 2024 | Neural Regeneration Research2024，19，5： | 0 |
