    The concept of Wijsman I2- Statistical Convergence (WI2StC), Wi[1]jsman I2 - Lacunary Statistical Convergence (WI2LStC), Wijsman Strongly I2 - Lacunary Convergence (WSI2LC) and Wijsman Strongly I2 - Cesaro Convergence (WSI2CeC) of double sequences in the Neutrosophic Metric Spaces (NMS) are examined in this paper. Ad[1]ditionally, we introduce the concepts of Wijsman Strongly I ∗ 2 - La[1]cunary Convergence (WSI∗ 2LC), Wijsman Strongly I2- Lacunary Cauchy (WSI2LCa), and Wijsman Strongly I ∗ 2 - Lacunary Cauchy (WSI∗ 2LCa) sequence in NMS and establish impressive results

    A Survey and New Perspectives on Classifying the DDOS Attack with Their Characteristics

    In network Distributed Denial of Service (DDoS) attacks has been a major threat to the Internet society. The DoS attack produces a large number of client bases due to the enslavement of major users on Web society. In such a DoS attack, the malicious invader targets a system to corrupt its services to the proposed users. These types of attacks are mainly motivated by the existence of different groups of hackers and crackers present on the network. The current research has progressed in this field; researchers have come across many ways through which attacks have been successfully launched. In early days of its origin, the Internet was not planned to face different vulnerable problems, in this aspect networks are need to protect. In this research paper covers the initiation of the DDoS attacks together with their types, and also deliberate certain model scenarios based on flooding based DDoS attacks to compute its impact on valid users and also we classified the different types of DDoS attacks with their environment and tabulated the results

    The Effectiveness of Teleglaucoma versus In-Patient Examination for Glaucoma Screening: A Systematic Review and Meta-Analysis

    BACKGROUND: Glaucoma is the leading cause of irreversible visual impairment in the world affecting 60.5 million people worldwide in 2010, which is expected to increase to approximately 79.6 million by 2020. Therefore, glaucoma screening is important to detect, diagnose, and treat patients at the earlier stages to prevent disease progression and vision loss. Teleglaucoma uses stereoscopic digital imaging to take ocular images, which are transmitted electronically to an ocular specialist. The purpose is to synthesize literature to evaluate teleglaucoma, its diagnostic accuracy, healthcare system benefits, and cost-effectiveness. METHODS: A systematic search was conducted to help locate published and unpublished studies. Studies which evaluate teleglaucoma as a screening device for glaucoma were included. A meta-analysis was conducted to provide estimates of diagnostic accuracy, diagnostic odds ratio, and the relative percentage of glaucoma cases detected. The improvements to healthcare service quality and cost data were assessed. RESULTS: Of 11237 studies reviewed, 45 were included. Our results indicated that, teleglaucoma is more specific and less sensitive than in-person examination. The pooled estimates of sensitivity was 0.832 [95% CI 0.770, 0.881] and specificity was 0.790 [95% CI 0.668, 0.876]. The relative odds of a positive screen test in glaucoma cases are 18.7 times more likely than a negative screen test in a non-glaucoma cases. Additionally, the mean cost for every case of glaucoma detected was 1098.67USandofteleglaucomaperpatientscreenedwas1098.67 US and of teleglaucoma per patient screened was 922.77 US. CONCLUSION: Teleglaucoma can accurately discriminate between screen test results with greater odds for positive cases. It detects more cases of glaucoma than in-person examination. Both patients and the healthcare systems benefit from early detection, reduction in wait and travel times, increased specialist referral rates, and cost savings. Teleglaucoma is an effective screening tool for glaucoma specifically for remote and under-services communities

    PEGylated polymer capsules encapsulating LaVO4:Tb3+, GdVO4:Tb3+, Gd2O3:Tb3+, GdF3:Tb3+, YVO4:Tb3+ and iron oxide nanoparticles are promising new fluorescence, magnetic and magnetofluorescence imaging agents. Recently, we have reported the in vitro and in vivo level toxicity profile which shows the non-toxic nature of polymer capsules encapsulating nanoparticles. However, prior to clinical use, it is essential to ensure that these agents are unlikely to activate immune responses. Herein, we investigated the immuno-compatibility of polymer capsules with dendritic cells (DC) and macrophages (MO), major antigen presenting cell (APC) subsets required for activation of innate and adaptive immunity. Capsules were efficiently internalized by both DC and MO in vitro. Importantly, despite the presence of intracellular capsules, there was no significant impact on the viability of cells. We studied the impact of different capsules on the cytokine profile of DC and MO, known to be important for the polarization of T-cell immunity. None of the capsules elicited change in cytokine secretion from DC. Furthermore, capsules did not alter the polarization of either M1 or M2 MO subsets as determined by the balance of IL-12 and IL-10 secretion. These data support the notion that PEGylated polymer capsules loaded with nanoparticles have the potential to remain immunologically silent as they do not activate APC and neither do they hinder the response of DC or MO to pathogen activating signals. These systems, therefore, exhibit promising characteristics for bioimaging applications. KEYWORDS: PEGylated polymer capsules, M1 and M2 macrophages, dendritic cells, immune respons
