On the basis of three-dimensional analysis of the humerus bones was shown that the plate, placed on posterior-and-medial surface of the lower section of these bones, should be twisted in terminal portions and bended on both ends in the contact surfac

A critical analysis is given of the well-known expression for the electron-impact ionization rate constant α i of neutral atoms and ions, derived by linearization of the ionization cross section σ i (e) as a function of the electron energy near the

This work suggests a method for construction of two-dimensional interpolation filters having isotropic spectral characteristics. Use of these filters makes it possible to avoid many artifacts arising during interpolation by traditional methods. Numer

A new representation for the complex Fresnel integral, allowing for its transformation into the trigonometric form, and its new interpretation based on the 2D Cornu spiral and a 3D spiral with a smooth envelope surface have been obtained. Within this

Our measurements of the arrival-time delays of radio pulses from the Crab pulsar, PSR B0531+21, at low frequencies 111, 63, and 44 MHz revealed additional delays compared to the usual quadratic frequency relation, Δt(v) ∝ v−2. These additional d
