The dramatic Mass Mortality Event, MME, of Pinna nobilis populations initially detected in the western Mediterranean basin, has also spread rapidly to the central and eastern basin. Unfortunately, there is still a significant lack of information on the s
GIS Based Analysis on Spatial Structure Urban Internal Population——A Case Study in Shenzhen City基于GIS 的城市内部人口空间结构研究 ———以深圳市为例 The population distribution reflects the mode of the urban internal population and social spatial structure.Because the population data is very easy ...
Finally, based on the quantitative measurement of the tourism economic resilience in urban agglomerations from 2006 to 2019, this paper uses MATLAB software to fit the improved climbing function curve simulation formula. It has passed the chi-square fitting goodness-of-fit test and obtained the opti...

To monitor signal drift during measurement, Rh was used as an internal standard. Whole rock standards GSR-1 (granite), BHVO-2 (basalt), and G-2 (granite) were processed together with samples and analytical accuracy was generally better than 5%. More details of the analytical procedure were ...
We begin by defining the population standard deviation of a random variable Z, denoted [[sigma].sub.Z], as the square root of the variance of Z: Computation of standard errors If the assumption of constant standard deviations of measurement errors is relaxed, the heteroscedasticity is characteriz...
15. Arbon.16described community resilience to disasters as “…where members of its population are connected to one another and work together, so that they are able to function and sustain critical systems, even under stress; adapt to changes in the physical, social or economic environment…”....
Here we tested the diagnostic performance of MDW in adult patients requiring hospital admission for community-acquired infections and sepsis, evaluated sources of heterogeneity in the estimates of diagnostic accuracy, and assessed the meaning of MDW in a patient population presenting to the emergency ...
