Similar to the movement of water, the fluctuation orbit of liquefied soil particles is elliptical with a horizontal major axis, and the orbit radius gradually decreases with depth. Although some researchers have constructed theories to describe the fluctuation of liquefied soils, no corresponding data ...
The deep learning DFT Hamiltonian (DeepH) method has been developed to improve the efficiency of electronic-structure calculation, which shows great potential to address the accuracy-efficiency dilemma of DFT8,9. A substantial generalization of the method is required to study a broad class of magne...
The matrix element Hiα,jβ (α and β refer to localized orbitals centered at atoms i and j) vanishes when the distance between atoms i and j is larger than a cutoff radius RC. RC is determined by the spread of localized orbitals, which is on the order of ångstroms, much smaller ...

Roughly speaking, the moon's orbit relative to the ecliptic is 18.6 years (like the precession of the earth, also known as the elevation of the equinoxes). Recently, moon will cyclical movement. The main items for about 8.85 years. In addition, the orbital radius of the moon around the ...
We can calculate the total amount of energy radiated by measuring the quantity of solar energy/second reaching every square meter of Earth and then multiplying that by the total surface area of a sphere with radius equal to the radius of Earth orbit. We get the astonishingly huge amount of ...

40.2.2 Positive Photon Velocity The principle of a positive photon obtaining speed c+ is the same as that of negative photons, (40.4), except that the radius of a proton rp is smaller, the mass of a proton mp is larger, and the charge-to-mass ratio is much smaller, taking rp = ...
Rξ and Rη are radius of curvatures. For a spherical effective surface, Rξ = Rη = R, where R is the radius of the sphere. For a parabolic effective surface, (22) with . xc and yc are the global coordinates of the centroid (gravity center) of the triangular facet. F′ is ...
