In the present study, we examined the potential contribution of irradiated medium to the bystander effect using custom-made double-Mylar stainless steel rings. Exponentially growing human-hamster hybrid (A(L)) cells were plated on either one or both sides of double-Mylar dishes 2-4 days before irradiation. One side (with or without cells) was irradiated with alpha particles using the track segm...

The paper studies the possibility of propagation of torsional surface waves in an elastic layer with void pores over an elastic medium with void pores using the mechanics of the medium as derived by Cowin and Nunziato. The velocity equation has been derived and the results have been discussed. The study reveals that there may be more than one torsional surface wave fronts and one Love wave fron...

In this work, we investigate the effect of broadband antireflection of a medium by a layer of embedded nano-cavities arranged near the surface. It is shown that this structure is versatile and allows near 100% transmittance in a wide spectral range practically for any dielectric material. The approximate model of nano-structured layer is suggested that allows to determine the parameters of the ...

In this paper we communicate recent developments in theory, experiment, and computer simulations of V-shaped waves in excitable media. The waves appear as the result of oblique collisions of two plane waves, and constitute a one-parametric family of V-like patterns distinguishable by the angle of collision. The shape and position of V-patterns are stable with respect to localized perturbations ...

A simple synthesis route for growth of Ag/AgO nanoparticles (NPs) in large quantitative yields with narrow size distribution from a functional, non-activated, Ni (II) based highly flexible porous coordination polymer (PCP) as a template has been demonstrated. This template is a stable storage media for the NPs larger than the pore diameters of the PCP. From EPR study it was concluded that NPs w...

The ever-increasing demand for high data storage capacity has spurred research on development of innovative technologies and new storage materials. Conventional GByte optical discs (DVDs and Bluray) can be transformed into ultrahigh capacity storage media by encoding multi-level and multiplexed information within the three dimensional volume of a recording medium. However, in most cases the rec...

A linear stability analysis is applied to a system consisting of three horizontal layers, a viscous fluid layer sandwiched between two porous medium permeated by the fluid that the lower layer is heated uniformlly from below. Flow in the porous medium is assumed to be governed by Darcy’s law. The Beavers-Joseph condition is applied at the interface between any two different layers.Spectral meth...

ABSTRACT In this paper, we report multi-level storage (MLS) in multi-layer (ML) and single-layer (SL) phase-change memories (PCM). For the former ML-PCM device, the active medium with two layers of chalcogenide consists of a top 30-nm TiN/180-nm SbTeN/20-nm TiN/bottom 120-nm SbTeN stacked multi-layer. Three stable and distinct resistance states are demonstrated in both static and dynamic switch...

Routing in Wireless Networks is challenging because of the unpredictable behavior of the medium and the random variations in channel condition. All of these factors lead to poor performance in multi-hop wireless mesh networks specially with the conventional routing. In order to exploit all the advantages that the wireless medium offers, new routing metrics must be explored. These metrics should...
