基于1991-2020年伊犁河谷及其周边20个国家气象观测站的气象资料,根据树上干杏的生物学特性及影响其生长发育的主要气象因子,筛选出树上干杏种植气候适宜性区划指标,建立树上干杏气候适宜性区划指标的空间分布模型,通过重分类法将4类区划指标叠加处理,绘制伊犁河谷树上干杏种植气候适宜性区划图,为提高气候资源的利用率,合理划分伊犁河谷树上干杏的气候适宜种植区提供参考。结果表明:伊犁河谷树上干杏种植可划分为最适宜种植区、适宜种植区、次适宜种植区和不适宜种植区。最适宜、适宜种植区位于伊犁河谷北部、乌孙山北部及新源县东部海拔700-1200m河谷平原及浅山地带;次适宜区分别位于海拔<700m和1200-1500m的河谷平原及低山地带;不适宜区位于河谷海拔1500m以上的中高山区。

针对传统GPS多径抑制算法无法在复杂短时延多径情况下准确估计出Galileo BOC(1,1)多径信号,提出一种隐含多径数量参数的多径模型,并构造自适应遗传算法对实际多径信号进行估计。当实际多径参数变化不大时,引用上次估计的多径参数,直到多径模型发生较大变化时,再启动遗传算法进行多径估计。城市峡谷中多径信号频繁消失和出现,而文算法中隐含对消失多径信号的估计,当消失的多径信号再次出现时,可以快速获得多径估计模型。本算法对于BOC(1,1)多径信号估计更加准确,有效地减小复杂短时延多径环境下每个通道的伪距测量误差,从而提高了Galileo接收机的定位精度,并且在一定程度上减小了计算量。

基于位置的服务(LBS)变得日益普及,越来越多的研究开始关注如何对空间中的兴趣点(POI)做有效的检索.现有的方法提出了空间数据上的关键词检索,研究如何根据查询的位置和关键词找到相关的POI点.然而,现有方法主要对查询关键词进行精确匹配,不能支持模糊查询:当查询关键词与底层数据存在微小差异的时候,LBS系统不能返回相关的结果.为了满足移动用户的模糊查询需求,文中对空间数据上的Top-k关键词模糊查询问题进行研究:给定一组POI点,检索与查询关键词近似匹配且空间上距离相近的Top-k个结果.为了提供高效的模糊查询,文中首先定义了一种新型的相关性函数,综合考虑了文本相似性和空间距离,进而提出了一种有效的索引结构RegionTrie,并基于RegionTrie设计了高效的Top-k算法.真实数据集上的实验结果表明,文中提出的Top-k算法十分高效,性能远好于对比方法.

AIM To perform a meta-analysis assessing the value of gadoxetic acid-enhanced magnetic resonance imaging(Gd-EOB-MRI)in detecting small hepatocellular carcinoma(HCC)(≤2.0 cm)in patients with chronic liver *** Databases,including MEDLINE and EMBASE,were searched for relevant original articles published from January 2008 to February *** were extracted,and summary estimates of diagnostic accuracy indexes such as sensitivity,specificity,diagnostic odds ratio,predictive value,and areas under summary receiver operating characteristic curve were obtained using a random-effects model,with further exploration employing meta-regression and subgroup *** In 10 studies evaluating 768 patients,pooled perlesion sensitivity of Gd-EOB-DTPA was 91%(95%CI:83%-95%),with a specificity of 95%(95%CI:87%-98%).Overall positive likelihood ratio was 18.1(95%CI:6.6-49.4),for negative likelihood ratio(NLR)of 0.10(95%CI:0.05-0.19)and diagnostic odds ratio of182(95%CI:57-581).Subgroup analysis suggested that diagnostic performance of Gd-EOB-MRI for sub-centimeter HCC(≤1.0 cm)detection was low,with a sensitivity of69%(95%CI:59%-78%).In studies with both Gd-EOBMRI and diffusion-weighted imaging(DWI)performed,Gd-EOB-MRI/DWI combination was more sensitive than Gd-EOB-DTPA alone,whether for small lesions(86%vs77%)or sub-centimeter ones(80%vs 56%).CONCLUSION A limited number of small studies suggested that GdEOB-MRI has good diagnostic performance in the detection of small HCC(≤2.0 cm)among patients with chronic liver disease,but relatively lower performance for detection of sub-centimeter HCC(≤1.0 cm).Combination of Gd-EOB-MRI and DWI can improve the diagnostic sensitivity of MRI.

Twenty-three progressive extractions were performed to study individual humic acids (HAs) and humin fractions from a typical black soil (Mollisol) in Heilongjiang Province, China using elemental analysis and spectroscopic techniques. After 23 HA extractions the residue was separated into high and low organic carbon humin fractions. HA yield was the highest for the first extraction and then gradually decreased with further extractions. Organic carbon (OC) of the humin fractions accounted for 58% of total OC even after 23 successive HA extractions. In addition, the atomic C/H ratio decreased during the course of extraction while C/O increased; the E4/E6 ratio from the UV analysis decreased with further extraction while E2/E3 increased; the band assigned to aliphatic carbon (2930 cm-1) in the diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) spectra gradually increased with progressive extraction; the calculated ratio of the sum of aromatic carbon peak heights to that of aliphatic carbon
