Higher-order terms in mode conversion
Physics of Plasmas, 1998The development of model equations to describe mode conversion and tunneling in an inhomogeneous plasma usually uses expansions of the Modified Bessel functions in the parameter λ=12k⊥2ρL2, keeping only the lowest possible order to demonstrate tunneling.

Higher order hyperfine terms in the spin Hamiltonian
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1978Abstract The higher order hyperfine terms in the spin Hamiltonian are evaluated for the general case where the hyperfine interaction raises from the electron orbital angular momentum and the electron spin dipolar-nuclear spin angular momentum interactions of a d-electron associated dominantly with one nucleus coupling with another ...

Remainder terms in a higher order Sobolev inequality
Archiv der Mathematik, 2010A remainder term for a higher-order Sobolev embedding is obtained in this paper. More precisely, if \(\Omega\) is a bounded domain in \(\mathbb{R}^N\) with \(\mathbb{C}^m\) boundary (\(m>1\) is an integer), then there exists a constant \(c(\Omega, m)> 0\) such that \(\| u\|^2- S|u|^2_{2^*}\geq C|u|_w\) for any \(u\) in the space \(\{u\in H^m\Omega\mid ...

Long-term attraction in higher order neural networks
IEEE Transactions on Neural Networks, 1998Recent results on the memory storage capacity of higher order neural networks indicate a significant improvement compared to the limited capacity of the Hopfield model. However, such results have so far been obtained under the restriction that only a single iteration is allowed to converge.

Significant term extraction by Higher Order SVD
2009 7th International Symposium on Applied Machine Intelligence and Informatics, 2009In this paper, we present a novel method for term importance, called Tensor Term Indexing (TTI). This extracts significant terms from a document as well as a coherent collection of document set. The basic idea of this approach is to represent the whole document collection in a Term-Sentence-Document tensor and employs higher-order singular value ...

Higher Order Terms in the Lamb Shift Calculation
Physical Review Letters, 1960Following previously described techniques, the atomic energy level displacements of order alpha (Z alpha )/sup 6/ ln/sup 2/ (Z alpha )mc/sup 2/ have been calculated and yield a result in agreement with that of Layzer. An addition is introduced which corresponds to a change of gauge of the virtual photon defining one-photon Lamb shift and serves to ...

Higher order terms in the saddle point approximation
Proceedings of the IEEE, 1967An integral of the type which commonly occurs in radiation theory is evaluated by the method of steepest descent to optain a well-known asymptotic expansion. The coefficients of the first three terms of this expansion are given in terms of functions and derivatives of functions which appear in the integrand; the coefficient of the third term does not ...
