The scaled boundary finite element method(SBFEM) is a semi-analytical numerical method,which models an analysis domain by a small number of large-sized subdomains and discretises subdomain boundaries *** a subdomain,all fields of state variables including displacement,stress,velocity and acceleration are semi-analytical,and the kinetic energy,strain energy and energy error are all integrated *** advantages are taken in this study to develop a posteriori h-hierarchical adaptive SBFEM for transient elastodynamic problems using a mesh refinement procedure which subdivides *** only a small number of subdomains are subdivided,mesh refinement is very simple and efficient,and mesh mapping to transfer state variables from an old mesh to a new one is also very simple but *** 2D examples with stress wave propagation were *** results show that the developed method is capable of capturing propagation of steep stress regions and calculating accurate dynamic responses,using only a fraction of degrees of freedom required by adaptive finite element method.

AIM： To investigate the feasibility and safety of monopolar electrocautery shovel （ES） in laparoscopic total mesorectal excision （TME） with anal sphincter preservation for rectal cancer in order to reduce the cost of the laparoscopic operation, and to compare ES with the ultrasonically activated scalpel （US）. METHODS： Forty patients with rectal cancer, who underwent laparoscopic TME with anal sphincter preservation from June 2005 to June 2007, were randomly divided into ultrasonic scalpel group and monopolar ES group, prospectively. White blood cells （WBC） were measured before and after operation, operative time, blood loss, pelvic volume of drainage, time of anal exhaust, visual analogue scales （VAS） and surgery-related complications were recorded. RESULTS： All the operations were successful; no one was converted to open procedure. No significant differences were observed in terms of preoperative and postoperative d I and d 3 WBC counts （P = 0.493, P = 0.375, P = 0.559）, operation time （P = 0.235）, blood loss （P = 0.296）, anal exhaust time （P = 0.431）, pelvic drainage volume and VAS in postoperative d 1 （P = 0.431, P = 0.426） and d 3 （P = 0.844, P = 0.617） between ES group and US group. The occurrence of surgery-related complications such as anastomotic leakage and wound infection was the same in the two groups.CONCLUSION： ES is a safe and feasible tool as same as US used in laparoscopic TME with anal sphincter preservation for rectal cancer on the basis of the skillful laparoscopic technique and the complete understanding of laparoscopic pelvic anatomy. Application of ES can not only reduce the operation costs but also benefit the popularization of laparoscopic operation for rectal cancer patients.

一致性(agreement)和相关性(correlation)是两个广泛使用的概念,用来评估变量之间的关联。虽然二者相似且相关,但是它们代表关联完全不同的概念。评估变量之间的一致性假设变量测量的是相同的结构,而在变量测量完全不同的结构时也可以评估它们之间的相关性。这种概念上的差异就要求使用不同的统计方法,并且当评估一致性或相关性时,统计方法根据数据的分布和研究者的兴趣可能会有所不同。例如,Pearson相关性,作为评估连续变量之间相关性的一种普遍测量方法,只有用于符合线性关系的变量时才能提供有用的信息;当用于不符合线性关系的变量时就无法提供准确信息甚至会产生误导。同样地,内部相关性,作为一种评估连续变量之间一致性的常用方法,如果一致性不好的实质正好是研究兴趣所在,那么该测量就不能为研究者提供充分的信息。本报告回顾了一致性和相关性的概念,并讨论了几种常用方法在应用中的差异。

目的:以医学指标为参照依据,建立与健康密切相关的肥胖评价标准,为国内制定肥胖评价标准提供了一种新的理论与方法。方法:调查于2002-11在西安市完成。调查对象为无明显严重急、慢性疾患、无肥胖遗传史、居住5年或以上的常住女性居民108人,均知情同意。调查指标:①血压。②血脂、胰岛素:应用7170生化分析仪测定总胆固醇、三酰甘油、高密度脂蛋白胆固醇,应用FJ-2008Pγ放射免疫计测定胰岛素。依据《全国临床检验操作规程》中血压、血脂、胰岛素等临床医学指标的标准将受试者分为两组,在正常范围内者为正常组,超出正常范围者为异常组。③肥胖:体质量指数18.5￣23.9kg/m2为正常,24￣27.9kg/m2为轻度肥胖即超重,≥28kg/m2为肥胖。结果:①西安市中老年女性的体质量指数与收缩压、舒张压、三酰甘油、高密度脂蛋白胆固醇、胰岛素等医学指标呈正相关(P<0.05￣0.01)。②医学指标异常组调查对象的体质量指数均大于正常组(P<0.05￣0.01)。③随调查对象体质量指数的增加,医学指标异常率也不断增加。④医学指标异常数达到临界值以上时引发相关疾病的可能性很大。结论:西安地区中老年女性临床医学指标与体质量指数相关性较高,且随着肥胖程度增加其异常率同步提高。临床医学指标可以作为建立肥胖评价标准的重要科学依据。

High-quality,normalized differential vegetation index (NDVI) time-series data are fundamental for environmental remote sensing applications;however,their quality is often influenced by complicated factors such as atmospheric aerosols and cloud coverage. Hence,in the current study,a robust reconstruction method based on envelope detection and the Savitzky-Golay filter (ED-SG) was developed to reduce noise in the NDVI time-series. To verify the performance of ED-SG,simulation experiments were implemented and NDVI time-series samples were selected for different land cover types derived from MOD09gq,Sentinel-2 and Landsat 8 OLI of Yangtze River Basin,between December 2018 and December 2019. The experimental results yielded an agreement coefficient and variance of 0.9599 and 0.0006,respectively on simulated time-series,Additionally,the smoothness metrics of evergreen broadleaf forests,evergreen needleleaf forests,deciduous broadleaf forests,herbaceous,and croplands were 0.0019,0.0017,0.0012,0.0012,and 0.0013,respectively. Ultimately,the reconstructed time-series metrics showed significant improvements in robustness and smoothness over conventional methods. Moreover,the simplistic mechanisms of the ED-SG model enabled it to run effectively in the Google Earth Engine over the NDVI time-series of the whole Yangtze River Basin.
