W ith the advent of near-equilibrium growth techniques, it is now possible to synthesize virtually any type of crystalline nanostructure. Researchers can exert a fine control over size, shape and surface chemistry to tailor the properties of their nanomaterial to specific applications relevant to energy conversion, sensing, electronics and photonics. Once in a device, these nanostructures are f...

most codes such as api and bsi recommend morison’s equation to estimate hydrodynamic forces on offshore structures. significant differences exist among these codes due to using different methods of analysis and estimation of force coefficients. in this paper, data from full scale tests have been used to evaluate random waves and uniform current actions on the smooth piles. four time and frequen...

| The use of multiple transmitter and receiver antennas allows to transmit multiple signal substreams in parallel and hence to increase communication capacity. In order to distribute the multiple signal substreams over the MIMO channel, linear spacetime codes have been shown to be a convenient way to reach high capacity gains with a reasonable complexity. The space-time codes that have been int...

Background Late onset sepsis is a frequent complication of prematurity, associated with increased mortality and morbidity. Probiotics may prevent late onset sepsis in premature infants. The aim of this study was to determine prophylactic effect of oral probiotics in prevention of late onset sepsis of very preterm infants. Materials and Methods This study was a randomized, double blinded, placeb...

Exciting recent developments in wireless multiantenna communications have led to designs aiming mainly at one of two objectives: either high-performance by enabling the diversity provided by multi-input multi-output (MIMO) channels or high-rates by capitalizing on space-time multiplexing gains to realize the high capacity of MIMO fading channels. By concatenating a linear complex-field coder (a...

The journal has made several important changes this year. First, we moved to a rolling article publication mode; that is, articles are published as soon they fully reviewed, accepted and copyedited. This allows quicker diffusion of the studies authors’ work. Our second innovation been removing need register reader access contents. original rationale for was assess number readers journal; howeve...
