    Opis:
    The present study aims to evaluate the mutagenic potential of secondary metabolites viz. anthraquinone, β-sitosterol and quercetin present in Alternanthera tenella and their related analogus compounds similar in their molecular structure. Nine similar putative allelochemicals analogus to each of anthraquninone, β-sitosterol and quercetin respectively were selected, a total of twenty seven similar chemicals were studied for mutagenicity prediction. Ames mutagenicity prediction was carried out by using T.E.S.T. (Toxicity Estimation Software Tool) of USEPA. All experimental metadata were obtained from Toxicity Benchmark and T.E.S.T. The results clearly indicated that the allelochemicals, anthraquinone and its related eight compounds were mutagenic positive except benzanthrone (mutagenic negative) but all experimental data were found mutagenic positive. β-sitosterol showed mutagenic negative in both experimental and predicted value. It’s three related compounds were mutagenic positive but rest six related compounds mutagenic negative in predicted value while in experimental data, seven compounds were found mutagenic positive and rest two mutagenic negative. In case of quercetin, both data were obtained mutagenic positive while in related compounds, seven compounds were found to be mutagenic positive and two compounds mutagenic negative in predicted value. All were found to be mutagenic positive in experimental metadata. Such findings poses a curiosity that are there any possibilities of conversion or substitution in the position of aromatic ring of allelochemicals when present in soil? Because allelopathy depends upon several environmental stressors and mutagenicity may be induced by allelochemicals. It is suggesting for future research to detect metabolic pathway and mechanism of allelochemicals formation in A. tenella in presence of toxins in soil and to validate with other available 2D and 3D softwares.

    Opis:
    The cellular users, on high speed railways and highways, travel at a very high speed and follow a nearly straight path, in general. Thus, they typically undergo a maximum frequency of handovers in the cellular environment. This requires a very fast triggering of the handover. In the existing method of handover in 5G cellular communication, for high speed users, neither the decision-making of handover nor the triggering of handover is sufficiently fast. This can lead to poor signal quality and packet losses and in the worst case, radio link failure (RLF) during a handover. This paper proposes a forward handover based method, combined with PN sequence detections, to facilitate a quicker handover for high speed users on railways and highways. The proposed method adds some complexity but can offer a significant improvement in the overall handover delay. A simplistic simulation is used to demonstrate the improvement of the proposed method.
