It is shown that the temporal subaperture steering vector [[bar.a].sub.1] ([v.sub.p]) is still conjugate centrosymmetric. Subsequently, the smoothed data will be transformed into beam-Doppler domain, and unitary ESPRIT will be implemented for estimation of spacetime parameters.
(3) The parameter [phi] determines the symmetry of the concerned Gabor filter: [phi] = 0, [pi], the filter is centrosymmetric; [phi] = -[pi]/2,[pi]/2, the filter is anti-centrosymmetric.
In the present paper, we restrict ourselves to centrosymmetric T + H Bezoutians whose inverses are centrosymmetric T + H matrices.

The extensively delocalized [pi]-electron systems of these centrosymmetric compounds confer upon them, besides chemical and thermal stability, some other interesting spectroscopic, optical, and electrical properties that allow a great number of applications in fields such as optics [5, 6], electrochemistry [7], catalysis [8], and sensoring [9,10].
Collagen has highly crystalline triple-helix structure that is not centrosymmetric, which makes it extremely bright in SHG.
Below, we derive the Lagrangian and Hamiltonian of a hydrogen atom in the Earth gravitational field, taking into account couplings of kinetic and potential Coulomb energies of an electron with a weak centrosymmetric gravitational field.
