The two-loop massless off-shell QCD operator matrix elements to finite terms

Nuclear Physics B, 2022
We calculate the unpolarized and polarized two–loop massless off–shell operator matrix elements in QCD to O(ε) in the dimensional parameter in an automated way.

Large deflection analysis of frames by elements containing higher-order terms

Vietnam Journal of Mechanics, 2003
In this paper, the beam elements using higher-order terms for large deflection analysis of elastic frames are discussed. The elements based on the co-rotational method are derived using the strain energy and effective strains.

Fractional generalization of memristor and higher order elements [PDF]

Communications in Nonlinear Science and Numerical Simulation, 2013
Abstract Fractional calculus generalizes integer order derivatives and integrals. Memristor systems generalize the notion of electrical elements. Both concepts were shown to model important classes of phenomena. This paper goes a step further by embedding both tools in a generalization considering complex-order objects.

Steerable Higher Order Mode Dielectric Resonator Antenna With Parasitic Elements for 5G Applications

IEEE Access, 2017
This paper presents the findings of a steerable higher order mode (TE1δ3y) dielectric resonator antenna with parasitic elements. The beam steering was successfully achieved by switching the termination capacitor on the parasitic element.

Higher Order Lagrange Finite Elements In M3D [PDF]

, 2004
The M3D code has been using linear finite elements to represent multilevel MHD on 2-D poloidal planes. Triangular higher order elements, up to third order, are constructed here in order to provide M3D the capability to solve highly anisotropic transport ...

Polarization converter for higher-order laser beams based on the use of forming binary diffractive optical elements as beam splitter

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012
We propose a new approach to generating a pair of initial beams for a polarization converter that operates by summing up two opposite-sign circularly polarized beams.

Evaluation of hierarchical vector basis functions for quadrilateral cells [PDF]

, 2011
New hierarchical vector basis functions for quadrilateral cells are introduced, and the matrix condition numbers associated with their use are compared to those of existing vector basis families to assess the relative linear independence of the functions.
