The human immunodeficiency virus (HIV) is the agent of the global epidemic of the immune disease AIDS (acquired immunodeficiency syndrome). Therefore further investigations on the viral structure and molecular mechanisms are of particular importance in the search for medical therapies.
A novel strategy based on defect engineering is proposed for high-performance multilevel data storage in oxide-based resistive random access memory (RRAM). Key innovations are (i) material-oriented cell engineering for desired modification of physical locations of generated oxygen vacancies in resistive switching layer and (ii) innovative operation scheme to control the distribution of oxygen vacancy...
We report that the endurance degradation behaviors of transitional metal oxide (TMO) based resistive random access memory (RRAM) is dominated by three different steps and correlated with extra oxygen vacancy accumulation during SET/RESET switching process. The physical origin of endurance degradation due to the pulse voltage effect is verified by the measured data. The optimized operation schemes...
3D structured illumination microscopy (SIM) was used to image pores in liver sinusoidal endothelial cells that separate blood plasma from cells and debris before the plasma encounters the underlying hepatocytes. These structures have previously only been accessible to electron microscopy, but somewhat hampered by its low throughput, sample fixation, and the difficulty to simultaneously label multiple...
Theoretical model of symmetrical constrained damping structure for railway wheel is established based on complex stiffness method. Four parameters are related to the noise-restraint performance of wheel with damping treatment, which are the thickness of constrained layer, the thickness of damping layer, the loss factor and the complex shear module of damping material. Optimal calculation in the frequency...
