Rain attenuation is an important aspect of signal propagation mainly above 10 GHz frequency. It has also been found that the rain rate and attenuation profiles along the vertical and slant propagation path, especially at a higher rain rates and at tropical location. In this study, a simple approach is taken to study rain attenuation at various frequencies from propagation data and ground based radar...
. Negatively charged DNA can be compacted by positively charged dendrimers and the degree of compaction is a delicate balance between the strength of the electrostatic interaction and the elasticity of DNA. We report various elastic properties of short double-stranded DNA (dsDNA) and the effect of dendrimer binding using fully atomistic molecular dynamics and numerical simulations. In equilibrium...
Nucleic acid interaction with nanoscale objects like carbon nanotubes (CNTs) and dendrimers is of fundamental interest because of their potential application in CNT separation, gene therapy and antisense therapy. Combining nucleic acids with CNTs and dendrimers also opens the door towards controllable self-assembly to generate various supra-molecular and nano-structures with desired morphologies....
