We examine a rod piston-rotaxane system, where the positions of several mobile rings on the axle are controlled by an external force acting on one of the rings.This allows us to access the translational entropy of the rings.For a simple rotaxane molecule with an axle that has uniform ring-axle interactions along its length, the molecule behaves lik
In this article, the pull-in instability and dynamic characteristics of electrostatically actuated suspended microchannel resonators are studied.A theoretical model is presented to describe the pull-in effect of suspended microchannel resonators by considering the electrostatic field and the internal fluid.The results indicate Dinnerware Sets that
Abstract The ancestral sarbecovirus giving rise to SARS-CoV-2 is posited to have originated in bats.While SARS-CoV-2 causes asymptomatic to severe respiratory disease in humans, little is known about the biology, virus tropism, and immunity of SARS-CoV-2-like sarbecoviruses in bats.SARS-CoV-2 has been shown to infect multiple mammalian species, inc
Background: As the world is still being ravaged by the coronavirus disease 2019 (COVID-19) pandemic, the first line of prevention TV Remote lies in understanding the causative and preventive factors of the disease.However, given varied socioeconomic circumstances, there may be some inequality in the level of proper knowledge of COVID-19.Despite a p
Tabibzadeh and Baradaran Hemmati (2015) argue that the Persian Genitive constructions can be divided into attributive genitives and nominal genitives based on six criteria including the possibility of displacing the nominal and attributive dependents, adding the plural suffix, and the possibility of scrambling or topicalization.Attributive genitive
