In contrast, an inverse relation with the R0 value is noted for the parameters δ1, δ2, and σ (negative indices). The sensitivity index of R0 for the parameter β is 1, meaning that the basic reproduction number increases or decreases by the same percentage as the transmission rate ...
1b. Extreme severity indicates a case of increased extreme precipitation over the upper bound of the national standard, meaning that the national standard cannot explain extreme precipitation properties. This is implemented assuming the CIs are the effective range (black lines in Fig. 1a) of the ...
In contrast, North AmericanAythyaspp. tend to occupy larger, more stable water bodies and spend less time in shallow areas, particularly during winter.Aythyaspp. are highly philopatric, meaning habitat quality plays a lesser role in site selection, and their local movement is more restricted compa...
根据文章第一句 “About 90% of the population in the world is right- handed.”可知,世界上大约90%的人口是右撇 子。由此可知,全世界大约有10%的人是左 撇子。 2.D 细节理解题。根据第二段的最后两句 "There was no difference when they looked at the easier math problems. But left-handed ...
When you use statistics with this meaning, it is an uncountable noun. You use a singular form of a verb with it. Statistics has never been taught here before. 2. 'statistical' Don't use 'statistic' as an adjective to mean 'relating to statistics'. Use statistical. Statistical techniques ...
Data sets can be characterized by their central tendency, meaning the average location of the data points, and their dispersion, the amount of scatter or spread of the data points around the central average. In many situations, knowing the average of a data set is simply not enough to make...
During a session, players take turns to ‘lead’ sets of tunes, with other players joining in with tunes they recognise (Gagne 1996; Vallely 2011). Importantly for the present study, session tunes are almost always performed from memory, meaning that despite increasing commercialisation and ...
In general, DE and PSO are global optimization algorithms, meaning they aim to find the global optimum of a function rather than get stuck in local optima. However, some landscapes are harder to reach the global optimum when the population converges into a far region. In this paper, the ...
PE is estimated to increase from 0.6 to 0.8 billion by 2050 and then remain fairly constant to 2100 (Fig.2c). In addition, the ratio between the combined flood total PE and urban PE is relatively constant in time, meaning that PE is expected to remain split between urban and nonurban ...
This suggests that the population distribution among urban clusters also exhibits a centralization trend, meaning that the sources of population inflow into urban clusters include areas outside the clusters as well. Table 10 Centralization of population distribution across urban clusters. Full size table...
