Human behavior is known to be heterogeneous and fluctuates temporally. Many studies have focused on the fluctuation of Inter-Event Times (IETs), times between one action next in various types human behavior. The existence this cannot explained by a stationary random Poisson process called burstiness. In study, we collected physical activity data while specifying age subjects their situations (e...

Regarding the growing uses of the nanoclay for different applications nanoclay characterization has become highly important. However, there is not enough information about a developed characterization methodology of nanoclay materials. In this study the montmorillonite was purified using different physical or chemical methods and the purity of montmorillonite in the nanoclay samples were charac...

In this essay I first discuss the physical relevance of the inequality m ≥ √ |J | for axially symmetric (non-stationary) black holes, where m is the mass and J the angular momentum of the spacetime. Then, I present a proof of this inequality for the case of one spinning black hole. The proof involves a remarkable characterization of the extreme Kerr black hole as an absolute minimum of the tota...

Small-angle neutron scattering (SANS) has been used to extend the structural characterization of the MS2 phage by examining its physical characteristics in solution. Specifically, the contrast variation technique was employed to determine the molecular weight of the individual components of the MS2 virion (protein shell and genomic RNA) and the spatial relationship of the genomic RNA to its pro...
