Genes in multicellular organisms are expressed as part of a developmental program that is largely dependent on self-perpetuating higher-order chromatin states. The mechanism of establishing and maintaining these epigenetic events is well studied in Drosophila. The first known example of an epigenetic effect was that of (PEV) in Drosophila, which has been shown to be due to gene silencing via he...

The acute hemodynamic effects of either ethacrynic acid or furosemide were studied in 27 patients who underwent diagnostic right and transseptal left heart catheterization. Twenth-three patients had postcapillary pulmonary hypertension secondary to isolated or predominant mitral stenosis. Of these, 21 patients were in New York Heart Association functional class III, and one each in class II and...

BACKGROUND Following the declaration that President Mwai Kibaki was the winner of the Kenyan presidential election held on December 27, 2007, a period of post-election violence (PEV) took place. In this study, we aimed to identify whether the period of PEV in Kenya was associated with systematic changes in sexual assault case characteristics. METHODS AND FINDINGS Medical records of 1,615 pati...

in this paper, plug-in fuel cell electric vehicle (pfcev) is considered with dual power sources including fuel cell (fc) and battery energy storage. in order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. in order to simulate the...

Battery second use-putting used plug-in electric vehicle (PEV) batteries into secondary service following their automotive tenure-has been proposed as a means to decrease the cost of PEVs while providing low cost energy storage to other fields (e.g., electric utility markets). To understand the value of used automotive batteries, however, we must first answer several key questions related to ba...

Isotropic diffuse gamma-ray flux in the PeV energy band is an important tool for multimessenger tests of models origin high-energy astrophysical neutrinos and new-physics searches. So far, this has not yet been observed. Carpet-2 air-shower experiment capable detecting gamma rays with energies above 0.1 PeV. Here we report upper limits on isotropic from data obtained 1999-2011 2018-2022. These ...
