Helical self-assembly plays a unique role in regulating the localized excitations of π functional systems, which can also bring highly multi-scale orders, and show a special effect to tune the energy of electronics, vibration, and rotation of molecules. Due to controllable and dynamic property of chiral self-assembly, highly ordered and helical assemblies can be obtained to exhibit amplificatio...

background:diabetic foot affects more than 25% of diabetic patients and finally up to 20% of cases result in amputation. the most important factor resulting in severe complications or even death is lack of self-care. health locus of control has been introduced as one of health factors and predicting factors of self-care. this research was performed for analyzing the correlation between self-car...

Direct drives applications are more and more common and rise up the control weakness to parameters variation. New method have been created but are most of time complex to tune and need powerful processor. In this paper, state feedback controllers optimized by Linear Quadratic principle are shown up. These methods achieve cost requirements due to constant gain coefficients. Methods tune criterio...
