Archetypes are the images or patterns recurring again and again in literature through the ages. It also focuses on the minute difference between archetype and archetypal image as discussed by Jung with special reference to the characters and other images in the play beating relevance with the universal archetypes. This article also highlights the play as a connective link in the series of the different pieces of literature via the unique use of the psychic remnants. It emphasises on the different use of those remnants interwoven in the mosaic of the characters and plot of the play.展开更多

The Thomas-Fermi equation and the corresponding boundary conditions are derived for the crystal planar channels. The numerical solution for the electric field in the channels between (110) planes of the single crystal silicon and the critical angles of channelling protons in them arc shown. Reasonable agreements with the experimental data are obtained. The results show that the Thomas-Fermi method for the crystal works well in this study, and a microscopic research of the channel electric field with the contribution of all atoms and the atomic ionization being taken into account is practical.展开更多

Although embryonic stem cells can differentiate into motor neurons, alternative sources of motor neurons may be controllable for disease modeling and transplantation. Here, we show that human and mouse fibroblasts can be efficiently and directly converted into motor neurons by a cocktail of five small molecules, without the involvement of the neural progenitor stage. The chemically-induced motor neurons display the distinct neuronal morphology and express motor neuron markers. Interestingly, when the same chemical compounds were soaked in beads and implanted in the hypodermis of the back skins of mice, surrounding cells begin to express motor neuron markers,indicating in vivo motor neuron reprogramming. Taken together, we provide an efficient approach for chemically converting human and mouse fibroblasts into motor neurons suitable for cell replacement therapy and neurodegenerative disease modeling.展开更多

The Markovian and non-Markovian master equations for this composite system are solved and compared with the exact solution. The solving approach can be directly generalized to the solution of a V-type multilevel system dynamics interacting with a reservoir. The results further testify that these two kinds of master equations are exploited in different coupling regime, providing guidance for further application of these variants master equations to solve multilevel system dynamics without the exact solution.展开更多
