Many applications give rise to structured, in particular T-palindromic, matrix polynomials. In order to solve a polynomial eigenvalue problem P (λ)x = 0, where P (λ) is a T-palindromic matrix polynomial, it is convenient to use palindromic linearizations to ensure that the symmetries in the eigenvalues, elementary divisors, and minimal indices of P (λ) due to the palindromicity are preserved. I...

The interest in self-reciprocal polynomials in coding theory originated with Massey (1963, 1964), who has shown tha t whenever a self-reciprocal polynomial is used as a convolutional code-generating polynomial, the resulting code may be decoded backward us well as forward, with the same hardware and the same probabil i ty of decoding error. Let G( D ) = go 4glD 4g~D ~ 4" . . 4g , D ' , where n ...

Stimulation in the hypothalamus elicits locomotor stepping. Before stepping is initiated, head scanning movements occur. We determined the relationships between the latency of locomotor initiation and the number, extent and direction of the head scanning movements. Chronic stimulation electrodes were stereotaxically implanted in and around the hypothalamus of 29 rats. Under awake conditions, 38...

Nine subjects (6 males, 3 females) ranging in body mass from 90.9 to 45.5 kg ran repeated trials across a force platform while being filmed at 50 fps. The subjects ran five barefooted trials at each of three speeds: 3.35, 3.83, and 4.47 m s-I. Force data were collected on-line and analyzed for the magnitude and temporal characteristics of the initial impact (FZ1) peak and the active (Fz2) peak ...

In this paper new semi-empirical formulas are developed to evaluate the variation of both real and imaginary parts of soil complex permittivity with depth inside the earth's surface. Computed values using these models show good agreement with published measured values for soils of the same textures and same frequency band. Use of these models may serve to handle more accurate results especially...
