Interestingly, the age distribution of mortality by COVID-19 (the distribution of the proportion of deaths per age group among all deaths), is similar between Italy, Japan, and Spain, even though the number of deaths are quite different among them23–25 (Fig. 1). The reported ...
The rapid development of China's HSR benefits from government investment and support. One of the reasons is that the government believes that HSR not only serves as an important bridge for economic linkage between cities to promote their economic development, but also promotes the construction of ...
Therefore, the difference should be taken into account when a comparison is made between the simulation results of the k − ε model and the classical theory of river mechanics. Keywords: resistance k − ε model; mixing length model; turbulence; open-channel uniform flow 1. Introduction In...
Landsat NDVI appeared to be dominated by the signal from the interspace and was insensitive to subtle changes in the pinyon and juniper tree canopy. However, for short-statured sagebrush shrub and meadow communities, there was good agreement between the phenocam and Landsat NDVI as reflected in ...
The function relation has been detected between MC value for a mapped eigenvector and its corresponding eigenvalue as follows: MCj = n 1TC1 λj (3) Based upon these properties, the eigenvectors can be interpreted as follows: The first eigenvector E1 is the set of real numbers that has ...
Electrical characteristic experiments show that the discharge duration, the evolution of the gliding arc and the fracture frequency are affected by the pressure difference between the inlet and outlet of the igniter (∆p). With the increase in ∆p, the frequency of the trapezoidal envelope in ...
