In this paper, we research the characteristics of the Laguerre-Gaussian (LG01) beams generated in an Er:YAG ceramic solid state laser pumped by an annular beam.The generated two LG01 beams dustin johnson spider putter (LG0,+1 and LG0,-1 modes) were found to have different thermally induced polarization behaviors and alternately existed in the reson
Copper-based polycrystalline shape memory alloys (SMAs) have limitations for many practical applications due to their low superelasticity and low 5.7 procharger ductility.In order to overcome this situation, in recent years, the production of copper-based SMAs by directional solidification process has attracted the interest of many researches.In th
Abstract Pathogen-pathogen interactions represent a critical but little-understood feature of infectious disease dynamics.In particular, experimental evidence suggests that influenza virus and respiratory syncytial virus (RSV) compete with each other, such that infection with one confers temporary protection against the other.However, such interact
