The first passage time process of a Lévy subordinator with heavy-tailed Lévy measure has long-range dependent paths. The random fluctuations that appear in a natural scheme of summation and time scaling of such stochastic processes are shown to converge weakly. The limit process, which is neither Gaussian nor stable and which does not have the self-similarity property, is possibly of independen...

Based on electric conductivity and wide potential window of ionic liquid (IL) and electric property of single-wall carbon nanotubes (SWCNTs), composite material of IL-SWCNTs was prepared, glucose sensor was built with this material for immobilizing glucose oxidase (GOx). It showed good response, sensitivity and stability for long time for glucose detection. Linear range for the detection of glu...

    Background and objectives: Halitosis as a common dentistry ailment which has a prevalence of around 50% of the adult population. There are many dental formulations in traditional Persian pharmacy called “Gharagher”, “Mazmazeh”, “Sonoun”, etc for treatment of halitosis. In the present study, we have tried to describe the step by step moder...

Ultra-low coefficient of thermal expansion (CTE) is an elusive property, and narrow temperature ranges of operation and poor mechanical properties limit the use of conventional materials with low CTE. We structured a periodic micro-array of bi-metallic cells to demonstrate ultra-low effective CTE with a wide temperature range. These engineered tunable CTE thin film can be applied to minimize th...

The spinning limit for three different fibres (cotton, viscose rayon and polyester) on a Dref-3 friction spinning machine has been investigated. The change in yarn properties with progressive change in count has also been reported. The count range has been seen to be dependent on fibre type. As one progresses from very coarse to fine counts, the yarn tensile property remain fairly unaltered for...

A complex high-dimensional chaotic behavior, phase chaos, is found in the finite-dimensional Kuramoto model of coupled phase oscillators. This type of chaos is characterized by half of the spectrum of Lyapunov exponents being positive and the Lyapunov dimension equaling almost the total system dimension. Intriguingly, the strongest phase chaos occurs for intermediate-size ensembles. Phase chaos...
