Heterochromatin and associated gene silencing processes play roles in development, genome defense, and chromosome function. In many species, constitutive heterochromatin is decorated with histone H3 tri-methylated at lysine 9 (H3K9me3) and cytosine methylation. In Neurospora crassa, a five-protein complex, DCDC, catalyzes H3K9 methylation, which then directs DNA methylation. Here, we identify a...

In this paper presents new topologies Multilevel DC-DC buck-boost converter which consists of an inductor based boost circuit and a switched capacitor circuit has high voltage gain and flexible output voltage. Operation of these switching devices causes inherently nonlinear characteristic to the DC-DC Converters include buck-boost converter. It is suitable for a low voltage power source such as...

High gain DC-DC converters are increasingly being used in solar PV and other renewable generation systems. Satisfactory steady-state dynamic performance, along with higher efficiency, is a pre-requirement for selecting the converter these applications. In this paper, non-inverting high boost has been proposed. The proposed only one switch continuous input current reduced voltage stress across s...
