Detection techniques of selective forwarding attacks in wireless sensor networks: a survey

The wireless sensor network has become a hot research area due its wide range of application in military and civilian domain, but as it uses wireless media for communication these are easily prone to security attacks. There are number of attacks on wireless sensor networks like black hole attack, sink hole attack, Sybil attack, selective forwarding attacks etc. in this paper we will concentrate on selective forwarding attacks In selective forwarding attacks, malicious nodes behave like normal nodes and selectively drop packets. The selection of dropping nodes may be random. Identifying such attacks is very difficult and sometimes impossible. In this paper we have listed up some detection techniques, which have been proposed by different researcher in recent years, there we also have tabular representation of qualitative analysis of detection techniquesComment: 6 Page

AMELIORATIVE EFFECTS OF STEM BARK OF THE WONDER TREE, PROSOPIS CINERARIA (L.) DRUCE AGAINST LPS-INDUCED TOXICITY: AN IN VITRO STUDY

Objective: The present experimental investigation was planned to unravel and analyze the therapeutic potential of hydro-ethanol extract prepared from the stem bark of Prosopis cineraria against LPS-induced toxicity under in vitro conditions. Methods: Liver tissue samples from healthy Swiss albino male mice (Mus musculus) were used for the study. Liver homogenate (0.9 ml) was treated with 0.05 mg/ml of LPS along with 0.01 to 0.05 mg/ml of hydro-ethanol plant extract and allowed to incubate at 37˚C. The reactions were terminated at different time points at 0 min, 30 min, 1 h, 2 h, 4 h, 8 h and 24 h and alterations in oxidative stress (LPO, CAT, SOD, GSH, GST, and GPx) and biochemical parameters of hepatic toxicity (AST and ALT, ACP and ALP) were studied. Results: The results demonstrated that the obliterations in the levels of oxidative and biochemical parameters due to LPS induced toxicity were restored by the treatment with hydro-ethanol extract of Prosopis cineraria under in vitro conditions. The altered levels were biochemical parameters were observed at 0.05 mg/ml LPS concentration after 2 h; but administration of hydro-ethanol plant extract at concentration 0.04 mg/ml effectively reduced its level when compared to LPS treated samples under in vitro conditions Conclusion: The present research work unravelled the alleviating potential of a hydro-ethanol extract of Prosopis cineraria against LPS-induced toxicity by combating oxidative stress under in vitro environment

Statistical approximation properties of Stancu type qq-Baskakov-Kantorovich operators

In the present paper, we consider Stancu type generalization of Baskakov-Kantorovich operators based on the q-integers and obtain statistical and weighted statistical approximation properties of these operators. Rates of statistical convergence by means of the modulus of continuity and the Lipschitz type function are also established for said operators. Finally, we construct a bivariate generalization of the operator and also obtain the statistical approximation properties.Comment: 16. arXiv admin note: substantial text overlap with arXiv:1508.0586

THE MAJOR HISTOCOMPATIBILITY COMPLEX: A REVIEW

One of the important components of the immune system, the major histocompatibility complex (MHC) molecules allow T-lymphocytes to detect cells, such as macrophages, B-lymphocytes, and dendritic cells that ingest infectious microorganisms or the self-cells infected with microorganism. On being engulfed a microorganism, macrophage partially digests it and displays peptide fragments of the microbe on its surface, bound to MHC molecules and the T-lymphocyte recognizes the foreign fragment attached to the MHC molecule and binds to it, lead to stimulation of an immune response. The MHC molecule presents peptides from its own cell (self-peptides) in healthy self-cells to which T-cells do not normally react.Keywords: MHC, B Cells, T Cells, Antigen Processing.Â
