The formula above allows for two straightforward extensions. First, the same methodology can be used to calculate average carbon prices for ad hoc groups of countries; \({e}_{total}^{g}\) is then total emissions of that country group. Second, it can be used to calculate the average price...
Annual average temperature and precipitation, human activities, and slope had a positive impact on vegetation EVI changes, while solar radiation and aspect had a negative inhibitory effect. The effects of climate, terrain, and human activities on EVI changes exhibited significant spatial heterogeneity ...
while it showed high-intensity staining in ovarian cancer tissues, and the proportion of stained cells was greater than 75%. The antibody HPA07951 was found in normal colon tissues. The
Its calculation formula is as follows: 𝑆𝐴𝑂𝐷=𝑀𝑒𝑑𝑎𝑖𝑛(𝐴𝑂𝐷𝑗−𝐴𝑂𝐷𝑖𝑗−𝑖),2000≤𝑖<𝑗≤2021SAOD=MedainAODj−AODij−i,2000≤i<j≤2021 where 𝐴𝑂𝐷𝑖AODi and 𝐴𝑂𝐷𝑗AODj, respectively, present the annual average values...
The high 𝜎−σ-convergence rate and low 𝜆−λ-convergence rate in the central area indicate that the energy efficiency of the central area has converged toward a better average level. The 𝜆−λ-convergence rates of the central and western areas mean that the energy efficiency of ...
; avg., average value; sd., standard deviation; se., standard error; cv., coefficient of variance. It could be seen that fermentation at 60 h appeared to be a key observation point to distinguish different MonAzPs production profiles, as well as the watershed between the ascending phase ...
The average mean absolute error (MAE), mean relative error (MRE), and the root mean square error (RMSE) decrease with scaling from monthly to daily time steps by 36%, 56%, and 35%, respectively, and the same statistical indexes decrease by 13%, 15%, and 14%, respectively, when ...
These studies use traditional approaches to examine the convergence in terms of per capita CO2 emissions or emissions intensity. However, these traditional approaches, such as σ-convergence, β-convergence, and stochastic convergence, are based on models for average or representative economies, which ...
The regression coefficient of foreign capital utilization ranges from −0.437 to 0.294, with an average value of 0.036. Most of the significant impact areas are coastal regions and show different effects (Figure 9). The influence channels of FDI on industrial eco-efficiency are mainly divided int...
where Moran’s I is the global Moran’s index, n is the number of ancient trees, xi and xj denote the ancient trees in the ith and jth cells, respectively, 𝑥̲x¯ is the average of all ancient trees, wij is the spatial weight matrix, Gi* is the Getis–Ord hotspot analysis ...
