Over the last several decades, increased agricultural production has been driven by improved agronomic practices and a dramatic increase in the use of nitrogen-containing fertilizers to maximize the yield potential of crops. To reduce input costs and to minimize the potential environmental impacts of nitrogen fertilizer that has been used to optimize yield,(More)
This paper presents an efficient carbon nanotube (CNT) transistor modeling technique that is based on cubic spline approximation of the nonequilibrium mobile charge density. The approximation facilitates the solution of the self-consistent voltage equation in a CNT so that calculation of the CNT drain–source current is accelerated by at least two orders of(More)
This paper presents a new carbon nanotube transistor (CNT) modelling technique which is based on an efficient numerical piece-wise non-linear approximation of the non-equilibrium mobile charge density. The technique facilitates the solution of the self-consistent voltage equation in a carbon nanotube such that the CNT drain-source current evaluation is(More)
This paper introduces a novel numerical carbon nanotube transistor (CNT) modelling approach which brings in a flexible and efficient cubic spline non-linear approximation of the non-equilibrium mobile charge density. The spline algorithm creates a rapid and accurate solution of the numerical relationship between the charge density and the self-consistent(More)
Recently proposed circuit-level models of carbon nanotube transistor (CNT) for SPICE-like simulators suffer from numerical complexities as they rely on numerical evaluation of integrals or internal Newton-Raphson iterations to find solutions of non-linear dependencies or both. Recently an approach has been proposed which eliminates the need for numerical(More)
Our study aimed to produce the commercially promising platform chemical 3-hydroxypropionic acid (3-HP) via the propionyl-CoA pathway in genetically engineered Escherichia coli. Recombinant E. coli Ec-P overexpressing propionyl-CoA dehydrogenase (PACD, encoded by the pacd gene from Candida rugosa) under the T7 promoter produced 1.33 mM of 3-HP in a shake(More)
This contribution presents a VHDL-AMS implementation of a novel numerical carbon nanotube transistor (CNT) modelling approach which relies on a flexible and efficient cubic spline non-linear approximation of the non-equilibrium mobile charge density. The underlying algorithm creates a rapid and accurate solution of the numerical relationship between the(More)
This paper presents the algorithms of an implementation of a numerically efficient carbon nanotube transistor (CNT) model in HSPICE. The model is derived from cubic spline non-linear approximation of the non-equilibrium mobile charge density. The spline algorithm exploits a rapid and accurate solution of the numerical relationship between the charge density(More)
