Abstract The effects of second-neighbor interactions in Kekulé-Y patterned graphene electronic properties are studied starting from a tight-binding Hamiltonian. Thereafter, low-energy effective Hamiltonian is obtained by projecting the high energy bands at ? point into subspace defined Kekulé wave vector. spectrum low excellent agreement with one numerical diagonalization full main effect secon...

there are many different ways to subdivide the spectrum of a bounded linear operator; some of them aremotivated by applications to physics (in particular, quantum mechanics). in this study, the relationship betweenthe subdivisions of spectrum which are not required to be disjoint and goldberg's classification are given.moreover, these subdivisions for some summability methods are studied.

I N i earlier publication it was pointed out that x-ray spectroscopy was, potentially, a practical tool for the routine analysis of the elements in biologic systems (1), and was particularly applicable to the problems of the clinical laboratory (2). This is the first of a series of studies designed to evaluate this method of analysis for the routine laboratory of clinical chemistry. Specificall...

The purpose of the present study was to re-examine diagnostic data from a state-wide autism prevalence study (n = 489) conducted in the 1980s to investigate the impact of broader diagnostic criteria on autism spectrum disorder (ASD) case status. Sixty-four (59 %) of the 108 originally "Diagnosed Not Autistic" met the current ASD case definition. The average IQ estimate in the newly identified g...
