1东亚夏季风的模拟研究──3个区域气候模式的对比显示文摘全球环流模式在东亚地区模拟可靠性评估研究表明存在不确定性,尤以降水更明显.该模式更难于模拟小范围(如一个省)和小时间尺度(如日)的气候变化.本研究用3个区域气候模式作1991年东亚夏季(5~8月)季风洪涝气候的模拟.其模拟结果与观测场作了严格的对比并进行了3个模式的相互对比.研究表明,3个区域气候模式成功地模拟了1991年夏季发生在我国江淮流域及日本南部的洪涝和几次特大暴雨过程以及相应的大气环流形势的分布.赵宗慈 罗勇 R.Leung S.Ghan W.C.Wang H.Wei 1997应用气象学报1997,8,A00:27
2Venetoclax联合低剂量阿糖胞苷治疗不耐受强化化疗的初治急性髓系白血病患者:一项Ⅲ期随机、安慰剂对照试验中中国队列结果显示文摘目的:探讨Venetoclax联合低剂量阿糖胞苷(LDAC)在不能耐受强化诱导化疗的中国急性髓系白血病(AML)患者中的疗效及安全性。方法:一项Ⅲ期随机、双盲安慰剂对照试验(VIALE-C)中中国队列的结果。在本项国际临床试验中,入组了不适合接受强化化疗、新诊断为AML的18岁或以上的成人患者。在全球范围内,患者(211例)按2∶1的比例随机分配接受Venetoclax+LDAC或安慰剂+LDAC(28 d为1个周期),在第1~10天接受LDAC。主要研究终点为总生存(OS);次要研究终点包括缓解率、无事件生存期及不良事件(AE)。结果:入组15例中国患者(Venetoclax组9例;安慰剂组6例)。中位年龄为72(61~86)岁。与安慰剂组相比,Venetoclax组的死亡风险下降38%(HR=0.62,95%CI 0.12~3.07)。对延长6个月随访进行的计划外分析显示,Venetoclax组的中位OS时间为9.0个月,安慰剂组为4.1个月。完全缓解(CR)率与血细胞计数未完全恢复的CR(CRi)率分别为33%(3/9)和0(0/6)。最常见的非血液学AE(Venetoclax组与安慰剂组)为低钾血症(5/9和4/6)、呕吐(4/9和3/6)、便秘(2/9和4/6)和低白蛋白血症(1/9和4/6)。结论:Venetoclax联合LDAC在中国患者中表现出有意义的疗效和可管理的安全性特征,这与在全球VIALE-C人群中的观察结果一致,使其成为不适合接受强化化疗的新诊断AML患者的一个重要治疗选择。胡豫 金洁 张钰 胡建达 李军民 魏旭东 高素君 Zha Jiuhong Jiang Qi Wu Jun Wellington Mendes Andrew H.Wei 王建祥 2021中华血液学杂志2021,42,4:7
3Synthesis of Ni nanowires via a hydrazine reduction route in aqueous ethanol solutions assisted by external magnetic fields显示文摘One-dimensional Ni nanostructures were synthesized via a hydrazine reduction route under external magnetic fields. The mixture of de-ionized water and ethanol was used as the reaction solvent and hydrazine hydrate as reducing agents. The morphology and properties of Ni nanostructures were characterized by X-ray diffractometer(XRD), scanning electron microscopy(SEM), and vibrating sample magnetometer(VSM). It was found that the magnetic field strength, concentration of Ni ions,reaction time and temperature as well as p H values played key roles on formation, microstructures and magnetic properties of Ni nanowires. The optimal wires have diameter of ~200 nm and length up to ~200 μm. And their coercivity is ~260 Oe, which is much larger than the commercial Ni powders of 31 Oe. This work presents a simple, low-cost, environment-friendly and large-scale production approach to fabricate one-dimensional magnetic materials. The resulting materials may have potential applications in conductive filters, magnetic sensors and catalytic agents.L.Y.Zhang J.Wang L.M.Wei P.Liu H.Wei Y.F.Zhang 2009Nano-Micro Letters2009,1,1:4

7Real-time vehicle-to-grid control for frequency regulation with high frequency regulating signal显示文摘The large-scale popularization of electric vehicles(EVs)brings the potential for grid frequency regulation.Considering the characteristics of fast response and adjustment of EVs,two control strategies of automatic generation control(AGC)with EVs are proposed responding to two high frequency regulating signals extracted from area control error(ACE)and area regulation requirement(ARR)by a digital filter,respectively.In order to dispatch regulation task to EVs,the capacity of regulation is calculated based on maximum V2G power and the present V2G power of EVs.Finally,simulations based on a two-area interconnected power system show that the proposed approaches can significantly suppress frequency deviation and reduce the active power output of traditional generation units.H.Liu K.Huang Y.Yang H.Wei S.Ma 2018Protection and Control of Modern Power Systems2018,3,1:0
