1 A method is presented for blind system identii-cation in an impulsive environment, where the system output is described by a symmetric-stable(SS) law. The method employs either the phase or the magnitude of the recently proposed-Spectrum 1] of the system output. It is much simpler than the method proposed in 1] that also relies on the phase or magnitude of the-Spectrum, and provides the syste...
The putative occurrence of methane in the Martian atmosphere has had a major influence on the exploration of Mars, especially by the implication of active biology. The occurrence has not been borne out by measurements of atmosphere by the MSL rover Curiosity but, as on Earth, methane on Mars is most likely in the subsurface of the crust. Serpentinization of olivine-bearing rocks, to yield hydro...
The aim of the present paper is to study a Bochner Ricci semi-symmetric quasi-Einstein Hermitian manifold (QEH)n, a Bochner Ricci semi-symmetric generalised quasi-Einstein Hermitian manifold G(QEH)n and a Bochner Ricci semisymmetric pseudo generalised quasi-Einstein Hermitian manifold P (GQEH)n.
This paper analyzes English symmetrical predicates such as collide and match. Its point of departure is an analysis of the concept 'similar' from Tversky (1977) that appears to show that similarity is psychologically asymmetrical. One basis for this claim from Tversky is that the sentences North Korea is similar to Red China and Red China is similar to North Korea are assessed as differing in m...
Antinuclear antibodies (ANA) were demonstrated in 3 out of 10 Gordon setters with symmetrical lupoid onychodystrophy and in 5 out of 13 Gordon setters with black hair follicular dysplasia. Two dogs showed both symmetrical lupoid onychodystrophy and black hair follicular dysplasia, and one of these was ANA positive. The results suggest that symmetrical lupoid onychodystrophy and black hair folli...
~-RF power is usually transmitted into ,an accelerator section from a rectangular waveguide through a single coupling iris. This arrangement introduces phase and amplitude asymmetries into the coupler fields with which the beam interacts. Field distortion can be reduced by machining an offset into the cavity wall opposite the iris. However, the compensation is imperfect. In this paper we descri...
The edges of highly-connected symmetrical graphs are colored so that they form Hamiltonian cycles. As an introduction we discuss the coloring of the complete graphs K2m+1 for m>1, but the focus is on the graphs resulting from symmetrical perspective projections of the edges of the regular 4-dimensional polytopes into 3-space. The goal is to color all edges in these graphs with multiple congruen...
A 47 year-old woman with normal neurological examination and normal intelligence developed medically refractory seizures at the age of 13 years. Over time, six distinct types of partial seizure were identified: left cheek myoclonus, forced tongue movements followed by lower extremity thrashing movements, left arm numbness and tingling, rising epigastric sensation, visual distortion, and graying...
Clinical observations and findings on imaging are reported in six newborns with symmetrical thalamic lesions (STL). In three cases the diagnosis was confirmed by postmortem examination. Characteristic observations in this series and 17 previously reported cases include no evidence of perinatal asphyxia, high incidence of polyhydramnios, absent suck and swallow, absent primitive reflexes, apprec...
Neurology India | June 2005 | Vol 53 | Issue 2 Ring-enhancing lesions pose a common diagnostic challenge. This sign is invaluable in differentiating demyelination from other similar lesions, which usually show complete ring enhancement. The ring is complete towards the white matter, indicating active demyelination. An open-ring pattern of enhancement is more likely to be associated with demyeli...
