An economic technique for calculation of polarized bremsstrahlung process is proposed, assuming typical atomic momentum transfer q ≪ m. The adopted approach is based on the natural reduction of the matrix element to the form V γ + A5γ . Polarization distribution in the fully differential cross-section is analyzed. It is found that at a given momentum transfer to the atom polarization in the pla...

In recent work on the area of approximation methods for the solution of nonlinear differential equations, it has been suggested that the so-called generalized Taylor series approach is equivalent to the homotopy analysis method. In the present paper, we demonstrate that such a view is only valid in very special cases, and in general the homotopy analysis method is far more robust. In particular...

Nanocomposites provide new properties and exploit unique synergism between materials. Polyvinylidene fluoride (PVDF) is an ideal piezoelectric matrix applicable in nanocomposites in a broad range of industries from oil and gas to electronics and automotive. And boron nitride nanotubes (BNNTs) show high mechanical, electrical and chemical properties. In this paper, the critical torsional load of...

The effect of surface tension (theKelvin effect) on the equilibrium radius of an aqueous solution drop at fractional relative humidity h less than unity is analyzed mathematically. Expressions for the lowest-order corrections to the equilibrium radius and radius ratio (relative to the volume-equivalent dry radius rdry) due to the Kelvin effect are presented and compared with data for solution d...

BACKGROUND Symptomatic extensor tendon irritation is a frequent complication in volar plate osteosynthesis of distal radius fractures. It is typically caused by dorsal screw protrusion and overdrilling of the dorsal cortex. The use of self-drilling locking screws (SDLS) could overcome both causes. The practical applicability of SDLS depends on two prerequisites: (1) the feasibility of preoperat...

Abstrac tAn in-situ procedure for calibrating the equivalent radius and width of the coil transducer in rotating mode measurements for magnetic field quality analysis is proposed. The standard calibration procedure is not suitable when the coil is longer than the magnet under test, because an average value of the radius and of the width along the length as a whole is obtained. This problem incr...

A reiterative technique is developed for finding in normalized form the differential phase shift provided by the circular waveguide, completely filled with azimuthally magnetized ferrite which propagates normal TE01 mode. It consists in a repeated numerical solution of the structure’s characteristic equation, derived in terms of a definite complex Kummer confluent hypergeometric function, follo...

We developed a search-based technique to automatically synthesize sequences of method calls that are functionally equivalent to a given target method. This paper presents challenges and results of applying our technique to Google Guava. Guava heavily uses Java generics, and the large number of classes, methods and parameter values required us to tune our technique to deal with a search space th...
