We have performed a linear pulsational stability survey of 6 series of long period variable models with M = 1.0M⊙, L = 3000 − 8000L⊙, and (X,Z) = (0.700, 0.020), (0.735, 0.005). The dynamic and thermodynamic couplings between convection and oscillations are treated by using a statistical theory of nonlocal and time-dependent convection. The results show that the fundamental and all the low over...

In this paper we revisit observational data concerning RR Lyrae stars in Galactic globular clusters, presenting frequency histograms of fundamentalized periods for the 32 clusters having more than 12 pulsators with well recognized period and pulsation mode. One finds that the range of fundamentalized periods covered by the variables in a given cluster remains fairly constant in varying the clus...

Plasmonics is a promising field of nanophotonics dealing with light interaction with metallic nanostructures. In such material systems, hybridization of photons and collective free-electron oscillation can result in sub-wavelength light confinement. The strong light-matter interaction can be harnessed for, among many applications, high-density photonic integration, metamaterial design, enhanced...

In this paper, both experimental and modeling works were resorted to analyze the warpage and wire sweep of QFN molded strip. The effect of QFN package size was investigated to provide the relation between warpage and metal to mold compound ratio. Design guideline for optimum metal to mold compound ratio has been obtained. Nonlinear large deformation of finite element analysis has been performed...

We demonstrate possible scenarios for production of pure spin current and large tunnelling magnetoresistance ratios from elastic co-tunnelling and crossed Andreev reflection across a superconducting junction comprising of normal metal-superconductor-normal metal, where, the normal metal is a one-dimensional interacting quantum wire. We show that there are fixed points in the theory which corres...

Introduction: Microstrip have been developed due to specific features: high Q factor, low mutual coupling (often used at high field MRI for parallel imaging), and radiation losses are significantly reduced (which enhances SNR). Balanced feeding of the microstrip preserves the electrical symmetry with respect to the strip center, making the probe invariant under different loading conditions (dif...
