Abstract: Laser scanning confocal fluorescence microscopy (LSCM) is now an important method for tissue and cell imaging when the samples are located on the surfaces of glass slides. In the past decade, there has been extensive… read more here.

Abstract: Achieving exact balance between spatially separated gain and loss is generally regarded as a necessary condition for parity–time (PT)-symmetric optical systems [1]-[12]. We introduce generalized PT (gPT)-symmetric optical structures, which have an asymmetric and unbalanced… read more here.
