政府间跨域通办合作协议在社会各要素跨区域流动背景下的兴起是现代行政向服务行政转变的必然趋势,然而目前法学界对于政府间合作协议的类型化研究并不充分,不能及时有效回应行政管理实践中涌现的新问题,理论与实践存有的缺口需要通过行之有效的法律制度予以缝合。因此,文章在明确跨域通办合作协议的法律定位后,梳理跨域通办合作协议存在的法律问题,以全过程人民民主与依法行政理念为价值指引,为跨域通办合作协议的法律依据、内容程序、监督保障等方面的法律制度完善提供革新思路。

基于2001—2021年Landsat遥感数据,研究巢湖流域植被覆盖多年变化,利用时空地理加权模型探讨地形、气候及人类活动的驱动影响。结果表明:(1)流域内平均植被覆盖度0.75,近20 a总体呈增加趋势,增速0.12%/a;2009年前,呈下降趋势,2009年后,呈增加趋势。(2)流域内89.79%的区域植被覆盖度高于0.6,不同土地利用的植被覆盖度为林地>旱作农田>稀疏植被>灌溉农田>城市建成区>湿地,湿地受蓄水排涝功能的影响,植被覆盖度相对较低。(3)近20 a,34.78%的区域植被覆盖度发生变化,以增加趋势为主,面积占比62.73%,集中在合肥市老城区、山区林地、沿江北岸平原地带以及环巢湖湿地区域,政策上的生态环境保护和流域治理对植被覆盖产生正影响成效显著;减少趋势发生在城市外围和部分耕地区域,体现城镇化建设、耕地种植模式等人类活动对植被覆盖的负影响,对于引江济淮(派河—东淝河)段施工沿线和柘皋河流域植被覆盖度减少,应值得关注。(4)2010年前,地形因素的影响逐年降低,气候作用逐年增加,2010年后,地形因素持续增加并成为主要因素。(5)人类活动对植被覆盖的影响程度整体呈增强趋势,生态环境得到改善,增强幅度为0.013%/(10 a)。

以城市隧道深基坑升级改造工程为依托,对SMW工法桩围护加固过程中基坑围护结构、地表沉降及建筑物沉降的纵横向变形进行了分析,并基于有限差分理论,采用FLAC 3D软件分析了SMW工法桩围护加固过程中水泥土搅拌桩桩体桩径、H型钢分布及内支撑间距3种支护参数对基坑力学响应的影响。结果表明:SMW工法桩的应用能够有效控制由于土体开挖引起的坑底隆起、侧壁水平侧移以及地表沉降;围护结构和周边地表因处于不同的受力状态,表现出不同的沉降变形特征,靠近基坑未开挖处坑底隆起最大,未开挖处的支护结构和地表沉降的位移量最大;合理的SMW围护结构桩径和H型钢分布形式可以有效地控制基坑变形,最大控制提升率分别能达到73.9%和41.1%,但改变内支撑水平间距对深基坑变形的控制效果并不明显。

为探究异味奶粉是否存在耐热芽孢杆菌污染,本实验通过对异味奶粉进行100℃,10min热处理,并结合微生物分离纯化和形态观察共筛选得到6株耐热芽孢杆菌,经生化鉴定均为热葡糖苷酶地芽孢杆菌,并对其进行耐热性和耐酸性研究。结果表明:经118℃/10min热处理后除分离株HP3仍有芽孢残留,其余菌株均被100%杀灭;各分离株在pH≥4.5时均可良好生长,而在pH≤3.5时大部分菌株的生长都受到抑制,仅分离株HP3在pH为2.5时仍可缓慢生长。以耐受性最强的分离株HP3为实验对象,采用汽化过氧化氢消毒装置可完全杀灭空间内不同点位的钢片上接种的热葡糖苷酶地芽孢杆菌,杀菌效率高达6lg。实验为有效防控奶粉生产车间中热葡糖苷酶地芽孢杆菌的污染提供参考依据。

对酸碱滴定法测定葡萄发酵饮料中二氧化硫含量不确定度进行有效评定,找出影响其不确定度的关键因素。通过酸碱滴定法测定葡萄发酵饮料中二氧化硫的含量,建立相关的数学模型,并对各不确定度分量进行计算和评定。结果显示:当置信水平为95%,包含因子为k=2时,葡萄发酵饮料中二氧化硫的含量为(39.1±0.4)mg/L。检测结果的不确定度主要来源于样品重复性测定和滴定过程,另外,标准溶液的标定和稀释过程也是影响不确定度的关键因素。

BACKGROUND The neutrophil to lymphocyte ratio(NLR)has been reported as a novel predictor for atherosclerosis and car-diovascular *** study aimed to determine the effects of NLR on long-term clinical outcomes of chronic total occlusion(CTO)*** A total of 670 patients with CTO who met the inclusion criteria were included at the end of the follow-up *** were divided into tertiles according to their baseline NLR levels at admission:low(n=223),intermediate(n=223),and high(n=224).The incidence of major adverse cardiac events(MACEs)during the follow-up period,including all-cause death,nonfatal myocardial infarction(MI),or ischemia-driven revascularization,were compared among the three *** Major adverse cardiac events were observed in 27 patients(12.1%)in the low tertile,40(17.9%)in the intermediate tertile,and 61(27.2%)in the high NLR tertile(P<0.001).Kaplan-Meier analysis demonstrated a significantly higher incidence of MACE,ischemia-driven coronary revascularization,non-fatal MI,and mortality in patients within the high tertile than those in the low and intermediate groups(all P<0.001).Multivariable COX regression analysis showed that the high tertile of baseline NLR level showed a strong association with the risk of MACE(hazard ratio[HR]=2.21;95%confidence interval[CI]:1.21-4.03;P=0.009),ischemia-driven coronary revascularization(HR=3.19;95%CI:1.56-6.52;P=0.001),MI(HR=2.61;95%CI:1.35-5.03;P=0.043)and mortality(HR=3.78;95%CI:1.65-8.77;P=0.001).CONCLUSION Our findings suggest that NLR is an inexpensive and readily available biomarker that can independently pre-dict cardiovascular risk in patients with CTO.

Cross-matching is a key technique to achieve fusion of multi-band astronomical catalogs. Due to different equipment such as various astronomical telescopes, the existence of measurement errors, and proper motions of the celestial bodies, the same celestial object will have different positions in different catalogs, making it difficult to integrate multi-band or full-band astronomical data. In this study, we propose an online cross-matching method based on pseudo-spherical indexing techniques and develop a service combining with high performance computing system(Taurus) to improve cross-matching efficiency, which is designed for the Data Center of Xinjiang Astronomical Observatory. Specifically, we use Quad Tree Cube to divide the spherical blocks of the celestial object and map the 2D space composed of R.A. and decl. to 1D space and achieve correspondence between real celestial objects and spherical patches. Finally, we verify the performance of the service using Gaia 3 and PPMXL catalogs. Meanwhile, we send the matching results to VO tools-Topcat and Aladin respectively to get visual results. The experimental results show that the service effectively solves the speed bottleneck problem of crossmatching caused by frequent I/O, and significantly improves the retrieval and matching speed of massive astronomical data.
