The quantum theory of a damped harmonic oscillator has been continuously studied since 1939. For quantization, an oscillation usually uses reservoir that includes number finite and discrete oscillators. However, set oscillators is unable to study the Ohmic damping (damping proportional velocity). In this research, continuous used investigate damping. Using continuum instead will enrich results ...

in most cases atherosclerosis is the underlying cause of vascular diseases, including heart disease and stroke. it is believed that endothelial injury is the earliest change in the artery wall and that this precedes the formation of lesions of atherosclerosis. recent developments in the field of atherosclerosis have led to a renewed interest in the recognition of the parameter of time in the at...
