Suppression of Third-Order Intermodulation in a Klystron by Third-Order Injection

Physical Review Letters, 2003
The first observations and measurements are reported on suppression of the third-order intermodulation (IM3) product arising from nonlinear mixing of two drive frequencies in a klystron, by externally injecting a wave at the IM3 product frequency. Optimum amplitude and phase of the injected wave for maximum suppression are examined.

Third order linkage disequilibrium*

Tissue Antigens, 1984
For third order linkage disequilibrium there is a constraint on the maximum value the disequilibrium can take, given pairwise disequilibria values and allele frequencies. As distinct from second order disequilibrium (considered in the context of a two locus model) there is also in some cases a constraint on the minimum value. The appropriate procedures

Information and third order ontology

Biosystems, 1998
The question of 'a unified theory of information' is addressed from the logical position of many-valued ontologies. Information is described as an operational factor which forms a trans-contextural bridge between disjunct ontological systems (or monocontextures).

A Third Order Point Process Characteristic

Scandinavian Journal of Statistics, 1998
Second order characteristics, in particular Ripley's K‐function, are widely used for the statistical analysis of point patterns. We examine a third order analogue, namely the mean number T(r) of r‐close triples of points per unit area. Equivalently this is the expected number of r‐close point pairs in an r‐neighbourhood of the typical point.

Gaussian third-order Jacobsthal and Gaussian third-order Jacobsthal–Lucas polynomials and their properties

Asian-European Journal of Mathematics, 2020
In this paper, the Gaussian third-order Jacobsthal and Gaussian third-order Jacobsthal–Lucas polynomials are defined. Then Binet formula and generating functions of these numbers are given. Also, some summation identities for Gaussian third-order Jacobsthal and Gaussian third-order Jacobsthal–Lucas polynomials are obtained by using the recurrence ...

Theory of Third‐Order Nonlinear Photoconductivity and Third‐Order Photogalvanic Effect in Glass

physica status solidi (b), 1995
AbstractThe general theory of a third‐order generalized photoconductivity in glass is developed using a density matrix approach in the generalized master equation approximation. The theory is applied to third‐order photogalvanic effect in glass in connection with photoinduced second‐harmonic generation in silica.

Third Order Design

1985
The third order design (THOD) has been defined as the problem of improving, extending or densifying an existing network in an optimal way by introducing additional points and/or additional observations. Two generally different problems are coming up in the THOD: The one is the optimal improvement of the network the other is the optimal design of a ...

On a Nonlinear Binomial Equation of Third Order

Zeitschrift für Analysis und ihre Anwendungen, 1992
A necessary and sufficient condition for the solution of equation u''' + p(t)u^{\alpha} = 0 (\alpha > 0 an odd integer, p ≤ 0 on (a,\infty)) to be oscillatory and some ...

Third‐order aberrations of pseudophakic eyes

Ophthalmic and Physiological Optics, 1989
The aberrations of pseudophakic eyes were analysed by third‐order theory assuming thin intraocular lenses. Third‐order aberrations with spherical surfaced lenses are quadratic functions of lens shape. Spherical aberration and coma are generally the most rapidly changing aberrations, at small field positions, with change in lens shape.
