Background:In order to maximize capacity carried in fiber-optic communication systems, spectrally efficient modulation formats are being intensely investigated. One such modulation format is called Nyquist-WDM (Wavelength Division Multiplexing) which results in a rectangular-like spectrum and concur.....

Infra-red (IR) imaging (in the LWIR and MWIR bands) is widely used for observation and surveillance applications. Most of IR optical materials are very sensitive to temperature changes. This sensitivity is reflected in a temperature dependent refractive index, that in turn it affects the focal lengt.....

Streptococcus pneumoniae (S. pneumonia) is part of the flora of the human respiratory tract, and can cause mucosal and invasive infections such as otitis media, pneumonia, sepsis and meningitis. The mucosal epithelial surfaces, with their tight junctions, constitute the first line of defense that pr.....
