An increasing number of terrestrial- and space-based radio-communication systems are influenced by the ionospheric space weather, making state increasingly important to forecast. In this study, a novel extended encoder-decoder long short-term memory (ED-LSTME) neural network, which can predict total electron content (TEC) is proposed. Useful inherent features were automatically extracted from h...

An accurate estimation of ionospheric variables such as the total electron content (TEC) is important for many space weather, communication, and satellite geodetic applications. Empirical physics-based models are often used to determine TEC in these However, it known that cannot reproduce all variability due various reasons their simplified model structure, coarse sampling inputs, dependencies ...

ethanolic extract of leaves of elaeocarpus ganitrus was analyzed for their total antioxidant capacity, reducing power, metal chelating, abts+ (2, 2-azinobis-(3-ethylbenzothiazoline-6-sulphonate) radical scavenging and hydroxyl radical scavenging activities. the extract at 500 ?g/ml showed maximum iron chelating activity (76.70%) followed by the scavenging of the abts+ radical (55.77%) at the sa...

total phenolic contents (tpc) of five different extracts (petroleum ether, dichloromethane, ethyl acetate, ethanol and ethanol-water) of artemisia biennis willd were measured in this work. the antioxidant activity was investigated by three different methods: β-carotene bleaching (bcb) test, 2,2-diphenyl-1-picrylhydrazyl (dpph) radical scavenging method and ferrous ion chelating (fic) assay. amo...
