Abstract The light absorption of the water medium often caused underwater image enhancement to become challenging due loss in color channels where red vanished faster than others. affected quality especially having cast like greenish, bluish, and yellowish. Therefore, this paper introduced a Generalized Color Compensation (GCC) technique which will recompense based on maximum channel then remov...

The wavelength demultiplexer, using cascaded optical fiber gratings and circulators, was proposed and developed for application to optically amplified wavelength-division multiplexing (WDM) submarine cable systems with 100GHz channel spacing. Our proposed demultiplexer cannot only achieve high wavelength selectivity, small excess loss and effective allocation of dispersion compensation fibers f...

At the plasmon resonance, high Joule losses in a metal nanoparticle of a spaser result in its low Q-factor. Due to the latter, to achieve the spasing regime, in which the number of coherent plasmons exceeds the number of incoherent plasmons, unsustainably high pump rates may be required. We show that under the condition of loss compensation by a spaser driven by an external optical wave, the nu...

Dosage compensation refers to the equalization of X-linked gene transcription among heterogametic and homogametic sexes. In Drosophila, the dosage compensation complex (DCC) mediates the twofold hypertranscription of the single male X chromosome. Loss-of-function mutations at any DCC protein-coding gene are male lethal. Here we report a population genetic analysis suggesting that four of the fi...

1128 Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 13, No. 7, July 2007 Failure to report poultry deaths should be addressed and has several possible explanations. Farmers are accustomed to common yearly poultry deaths, which are not reported. In the absence of an offi cial compensation statement, farmers may fear income loss from massive poultry culling. Our results emphasize the need ...

The structure and regulation of the insurance system for financing workers' compensation affects the costs of workers' benefits. Using the example of Maine's insurance market restructuring in response to a crisis of the early 1990s, this commentary explores how changes in insurance regulation might better support the goals of workers' compensation. The commentary analyzes how insurance and its ...
