On the basis of the characteristic that X-rays radiate along a straight line and the principle that the contrast does not change when an object moves along an X-ray radiation direction, screw placement planes of surgical bone screws on two radiation directions at a 90 degree intersection angle...
Recently, the emergency of meta- optics provides an alternative to constructing compact and lightweight large-FOV metalens through elaborated phase modulation within a flat surface, showing great potential in surveillance, unmanned vehicles, onboard planes or satel- lites, medical science, and other ...
The conventional steel body of a car, on an average, contains 4500 spot weld joints. Resistance spot welding is the principle joining method used in automotive industries and has been for many years. In this method the joint is ...

tomography with a lower number of discrete exposures. This reduces the radiation exposure and operating costs. In addition, the use of approximation algorithms and digital processing allows a 3D image set to be reconstructed so that individual 2D planes of focus can be viewed through the 3D data...
This kind of welding is very popular in the industrial area. The technique is particularly useful for the manufacturers of aerospace & automotive, who use this welding to combine several metal parts within trucks, cars, planes & spacecraft. Because of the nature of electronic beam welding based...
In three-dimensional (3D) compounds, the bulk Rashba effect can depend on the inter-atomic orbital interaction, hindering the description of this effect by Equation (1) even in planes perpendicular to the electric dipole. Inspection of DFT results in Figure 1 shows, however, that this scaling ...
Obviously, the SU(2) invariance of each of the spin triplet states in Hilbert space represents the SO(3) invariant conservation of spin angular momentum 𝑆=1S=1 for each of the planes 𝑥𝑧xz (|𝜙+〉|ϕ+〉), 𝑦𝑧yz (|𝜙−〉|ϕ−〉), and 𝑥𝑦xy (|𝜓+...
Such procedure can minimize the distances from the photogrammetric matching points to the corresponding tangent planes of the terrestrial LiDAR data surface. However, the exact tangent plane corresponding to a certain photogrammetric matching point is difficult to identify, so the approximate tangent plane...
Figure 8 plots the difference charge density maps of the four new structures along selected planes at ambient pressure. In the present work, the charge density difference is defined as: Dr~rsc À ratom ð6Þ where rsc is the surface charge density obtained after self-consistent ...
