The thin lens equation is an equation that locates the image of a given object formed when it is placed in front of a lens. The "thin" part of a thin lens is an approximation that ignores almost all of the lens' properties...
water nanolayer, the capillary force is nonnegligible and contributes to the dynamic evolution of buckles. The capillary force, which is mainly ascribed to the negative pressure induced by the curvature of the water nanolayer (Fig.3d, inset)40, can be estimated by the following equation: ...
Step 6.Solve the appropriate equation for the quantity to be determined (the unknown), and enter the knowns. Slits, gratings, and the Rayleigh limit involve equations. Step 7.For thin film interference, you will have constructive interference for a total shift that is an integral number of wa...

This equation has been successfully applied in prior studies to model the relationship between the PCAS and the cooling rate for 316L stainless steels [16]. A Bruker D8 Advance diffractometer operating at V = 40 kV and I = 40 mA with Cu-Kα radiation was used for X-ray ...
Thouless (BKT)-like transition, as described in the following equation:31 $${R}_{xy}(T)={R}_{{\rm{N}}}\exp [-b{(\frac{T-{T}_{{\rm{BKT}}}{{T}_{{\rm{BKT}}})}^{(-1/2)}],$$ (1) Fig. 3 Electrical transport measurements.aTemperature dependence of the resistanceRxxfro...
C1represents the total capacitance of a picture element. RON1 and ROFF1 represent ON resistance and OFF resistance respectively of a TFT. Equation (1) should be satisfied by all of the picture elements of the matrix while in a holding operation (holding condition). If this condition is satisf...
