Multivariable equations are recommended by primary prevention guidelines to assess absolute risk of cardiovascular disease (CVD). However, current equations have several limitations. Therefore, we ...

Abstract: Based on deep neural network, elliptic partial differential equations in complex regions are solved. Accurate and effective strategies and numerical methods for elliptic partial differential ...

Abstract: The accuracy of the passive ranging solution obtained by using the difference approximation to the Doppler change rate is not good. By means of the frequency shift recurrence equation, the ...
