Secure IR Communication Design For Pre-Cardiac Arrest Detection In Wireless Body Area Network

This paper has got its vision and practical implementation from the basic idea with regard to Wireless Body Area Sensor Networks (WBASNs). The remote Body Area Sensor nodes are non-invasive which contributes to this project by making it more efficient in prototype design. The added features of low operating power and wireless intra IR communication have modified, the design and patient monitoring to a simplified version. Due to its low operating power and highly infrequent usage of the rechargeable battery power, the idea of zero maintenance is deployed. This system was developed for the earlier detection of cardiac arrest in human body. Though, numerous models were in existence, they are not practically suitable or considered as unique design for this highly secured and more miscommunicated wireless node communication. In this paper we have proposed a novel generation of a unique key for each of the patient to communicate with its own nearby node (mobile) and then to emergency unit. The basic demerit that existed in all the primitive models of direct communication with high power node has been eliminated in this proposed idea. When Wireless Body Area Sensor within two patients comes in more close proximity, there is a chance of cross communication or miscommunication i.e. picking up of sign signal of one patient by another patient (mobile) receiver. This leads to a chaotic situation and may even lead to the death of the patient if the other patient’s mobile sensor node is activated. For this reason, a unique ID is build which communicates with the mobile IR unit, where an android app is created to communicate through SMS with the patient caretaker, hospital and nearby ambulance network.

Analysis of challenging reconstruction of soft tissue defects around the knee joint and evolving a treatment algorithm

Background: The soft tissue defects around knee joint give a challenging experience to reconstruct. There are various ways to reconstruct soft tissue defects around knee joint. In this study, a reconstructive algorithm is formed for soft tissue defect around knee joint using pedicled flaps.Methods: Reconstructive procedures were done for 15 cases of soft tissue defects around knee joints following different etiologies during the tenure of January 2017 to December 2018 in the Department of Burns, Plastic and Reconstructive Surgery, Kilpauk Medical College, Chennai.Results: Soft tissue defects around knee joint need flap to have a durable cover, to protect the underlying structures – bones, vessels, tendon, and to enable ease of free movement of knee joint without producing contracture. There are various etiologies for soft tissue defects around knee joint-post traumatic injuries, post total knee replacement, post electric burn injuries, post burn scar contracture release of knee joint. 15 cases of soft tissue defects around knee joint were reconstructed using various pedicled flaps-medial thigh rotation flap, gastrocnemius muscle and myocutaneous flap, reverse anterolateral thigh flap, propeller flap. In this retrospective study, reconstructive algorithm for soft tissue defects around knee joint is provided.Conclusions: The reconstruction of soft tissue defects around knee joint is difficult one. In this study, a simple reconstructive algorithm is provided based on the experience in Department of Burns, Plastic, and Reconstructive Surgery, Kilpauk Medical College, Chennai

IMPROVING THE SCALABILITY BY CONTACT INFORMATION COMPRESSION IN ROUTING

ABSTRACT The existence of reduced scalability and delivery leads to the development of scalable routing by contact information compression. The previous work dealt with the result of consistent analysis in the performance of DTN hierarchical routing (DHR). It increases as the source to destination distance increases with decreases in the routing performance. This paper focuses on improving the scalability and delivery through contact information compression algorithm and also addresses the problem of power awareness routing to increase the lifetime of the overall network. Thus implementing the contact information compression (CIC) algorithm the estimated shortest path (ESP) is detected dynamically. The scalability and release are more improved during multipath multicasting, which delivers the information to a collection of target concurrently in a single transmission from the source

Characterization of Cold Sprayed CuCrAl-Coated and Uncoated GRCop-84 Substrates for Space Launch Vehicles

A newly developed Cu-23(wt.%)Cr-5%Al (CuCrAl) alloy is currently being considered as a protective coating for GRCop-84 (Cu-8(at.%)Cr-4%Nb). The coating was deposited on GRCop-84 substrates by the cold spray deposition technique. Cyclic oxidation tests conducted in air on both coated and uncoated substrates between 773 and 1073 K revealed that the coating remained intact and protected the substrate up to 1073 K. No significant weight loss of the coated specimens were observed at 773 and 873 K even after a cumulative cyclic time of 500 h. In contrast, the uncoated substrate lost as much as 80% of its original weight under similar test conditions. Low cycle fatigue tests revealed that the fatigue lives of thinly coated GRCop-84 specimens were similar to the uncoated specimens within the limits of experimental scatter. It is concluded that the cold sprayed CuCrAl coating is suitable for protecting GRCop-84 substrates

Non-coding and Coding Transcriptional Profiles Are Significantly Altered in Pediatric Retinoblastoma Tumors.

Retinoblastoma is a rare pediatric tumor of the retina, caused by the homozygous loss of the Retinoblastoma 1 (RB1) tumor suppressor gene. Previous microarray studies have identified changes in the expression profiles of coding genes; however, our understanding of how non-coding genes change in this tumor is absent. This is an important area of research, as in many adult malignancies, non-coding genes including LNC-RNAs are used as biomarkers to predict outcome and/or relapse. To establish a complete and in-depth RNA profile, of both coding and non-coding genes, in Retinoblastoma tumors, we conducted RNA-seq from a cohort of tumors and normal retina controls. This analysis identified widespread transcriptional changes in the levels of both coding and non-coding genes. Unexpectedly, we also found rare RNA fusion products resulting from genomic alterations, specific to Retinoblastoma tumor samples. We then determined whether these gene expression changes, of both coding and non-coding genes, were also found in a completely independent Retinoblastoma cohort. Using our dataset, we then profiled the potential effects of deregulated LNC-RNAs on the expression of neighboring genes, the entire genome, and on mRNAs that contain a putative area of homology. This analysis showed that most deregulated LNC-RNAs do not act locally to change the transcriptional environment, but potentially function to modulate genes at distant sites. From this analysis, we selected a strongly down-regulated LNC-RNA in Retinoblastoma, DRAIC, and found that restoring DRAIC RNA levels significantly slowed the growth of the Y79 Retinoblastoma cell line. Collectively, our work has generated the first non-coding RNA profile of Retinoblastoma tumors and has found that these tumors show widespread transcriptional deregulation
