To accurately describe such a spatiotemporal process of diffusion, a couple of key elements are needed, such as the source of infection, the intensity, the time and the distance of propagation as well as the propagated channels (paths). The end result is the whole process either “disappears...
2). These epidemic diseases rapidly spread to different territories across the globe, resulting in thousands of cases of infection and deaths (Zhang et al., 2019). These infections can spread exponentially among community by multiple ways like direct contact, cough, or sneeze or even sometime ...
Usually, the wavelength spectrum of the emitted light and that of the light source are different. It is generally necessary to place a filter between the sample and the CMOS image sensor to filter out the original wavelength spectrum of the light source in a fluorescent lens-less microscope [...
