We estimate the fluctuation width of an energy level as a function of the number of electrons added to a Coulomb-blockade quantum dot. A microscopic calculation in the limit of Koopmans’ theorem predicts that the standard deviation of these fluctuations is linear in the number of added electrons, in agreement with a parametric random-matrix approach. We estimate the number of electrons it takes...

This paper aims to establish the relationship between two apparent disparate problems: (i) the aggregation of uncertain information modelled by type-1 fuzzy sets via OWA mechanism, and (ii) the computation of the centroid of type-2 fuzzy sets. In order to cut down the computational complexity of the direct approach to performing type-1 OWA operation, the α-level approach to type-1 OWA operators...

α-Fe2O3 (hematite) nanoparticles were synthesized using tragacanth gel as biotemplate andiron chloride as the iron source by the sol-gel method. This method has many advantages suchas nontoxic, economic viability, ease to scale up, less time consuming and environmentalfriendly approach for the synthesis of α-Fe2O3 nanoparticles without using any organicchemicals. Nanoparticles were characterize...

Let G= (V,E,σ,μ) be a simple connected undirected fuzzy graph. In this paper, we use a fuzzy graph model to represent a traffic network of a city and discuss a method to find the different type of accidental zones in a traffic flows. Depending on the possibility of accident, this paper classifies accidental zone of a traffic flow into three type’s namely α-strong, β-strong and δ-strong accident...

In this paper, the ratio of product of two α-k-μ random variables and α-k-μ random variable is analyzed. The closed form expression for average level crossing rate (LCR) of the ratio of product of two α-k-μ random variables and α-k-μ random variable is determined. The expression for level crossing rate of the ratio of product of two α-k-μ random variables and α-k-μ random variable can be used f...

Increasing evidence points to inflammation as a chief mediator of Parkinson's disease (PD), a progressive neurodegenerative disorder characterized by loss of dopamine neurons in the substantia nigra pars compacta (SNpc) and widespread aggregates of the protein α-synuclein (α-syn). Recently, microRNAs, small, noncoding RNAs involved in regulating gene expression at the posttranscriptional level,...
