Relatively little is known about the impact of global warming on the tropical cyclone(TC)outflow,despite its large contribution to TC *** this study,based on the International Best Track Archive for Climate Stewardship(IBTrACS)dataset and ERA5 reanalysis data,we show that the TC outflow height has risen significantly(48.20±22.18 m decades-1)in the past decades(1959-2021)over the western North Pacific,and the rising trend tends to be sharper for stronger TCs(the uptrend of severe typhoon is 61.09±40.92 m decades-1).This rising trend of the outflow height explains the contradiction between the decrease trend of the TC outflow temperature and the increase trend of the atmospheric troposphere ***,possible contribution of the TC outflow height uptrend to TC intensity has also been *** results show that the rise of outflow height leads to the decrease of outflow temperature,and thus an increased difference between underlying sea surface temperature(SST)and TC outflow temperature,which eventually favors the increase of TC intensity.

A campus bus network design and evaluation, taking Tsinghua University as an example, is investigated in this paper. To minimize the total cost for both passengers and operator, the campus bus system planning in a sequential approach is discussed, including the route network design, headway （i.e., the inverse of service frequency） optimization, and system evaluation. The improved genetic algorithm is proposed to optimize the route network based on the route property, and the impacts of the fluctuation of passenger demand and average traveling time are analyzed. The identity proportion in the headway optimization is then introduced with full consideration of its impacts. Based on the actual variety of passenger demand, a non-fixed schedule demonstrates its efficiency. VISSIM is finally adopted to simulate the campus bus system and a comprehensive evaluation system for the campus bus is developed. Compared with the current bus network and the one without considering the route property, the evaluation of the proposed approach shows an improvement of 18.7% and 10.1%, respectively. Moreover, the sequential approach shows an efficiency significance for the development of public transit systems passengers and operator. mprovement over the alternative method. It is of great n large industrial parks to decrease the total cost for both

目的:分析阑尾子宫内膜异位症的临床病理特点。方法:回顾分析2005年8月至2022年4月病理确诊的14例阑尾子宫内膜异位症患者的临床资料。结果:患者发现阑尾子宫内膜异位症时中位年龄43.5(35.0,46.0)岁,小于30岁占7.1%(1例),30~40岁占28.6%(4例),40~50岁占50.0%(7例),大于50岁占14.3%(2例)。9例(64.3%)患者术前存在痛经症状,术后痛经症状均缓解。12例(85.7%)患者病理证实阑尾存在急慢性炎症,4例(28.6%)临床诊断为原发性不孕症。患者术前检查均未提示阑尾子宫内膜异位症,均为术后病理诊断。1例(7.1%)患者术前主要诊断为阑尾肿物,1例(7.1%)主要诊断为卵巢肿物,术前主要诊断为卵巢囊肿、急慢性阑尾炎、卵巢恶性肿瘤、子宫肌瘤各3例(21.4%)。4例(28.6%)因阑尾急慢性炎症或阑尾肿物切除阑尾,6例(42.9%)因术中见阑尾形态异常而切除阑尾,3例(21.4%)因卵巢恶性肿瘤常规切除阑尾,1例(7.1%)为右侧附件切除术中见阑尾与卵巢粘连紧密而切除阑尾。3例合并剥除卵巢囊肿、1例合并切除右侧卵巢,病理证实均存在卵巢子宫内膜异位囊肿;4例同时切除子宫及一侧或双侧附件,其中3例同时存在卵巢子宫内膜异位囊肿及子宫腺肌病,1例存在子宫腺肌病。阑尾子宫内膜异位位置:肌层7例(50%),外膜3例(21.4%),浆膜1例(7.1%),3例(21.4%)位于肌层及外膜;1例合并阑尾黏液腺瘤,1例合并阑尾黏液腺瘤及阑尾类癌。患者均经腹腔镜手术切除阑尾。结论:对于临床确诊子宫内膜异位症的孕龄期妇女,尤其存在反复右下腹疼痛的患者,妇科与外科医师需仔细鉴别排查阑尾子宫内膜异位症的可能。如果阑尾存在子宫内膜异位,会引起阑尾急、慢性炎症,通常需要手术治疗,需引起妇科及外科医师的高度重视。
