      • A Comparative Study of Existing Cluster-Based Routing Protocols in Wireless Sensor Networks

        Pooja Mishra,Sanjiv Sharma 보안공학연구지원센터 2016 International Journal of Future Generation Communi Vol.9 No.7

        Wireless Sensor Network (WSN) has grown vastly in the past few years and pointing out the crucial need for scalable and energy efficient network. Routing in WSN is challenging task because of limited resources of available energy and processing power. On the basis of network structure, routing protocol in WSN can be classified into two different categories such as flat routing and cluster-based or hierarchical routing. In literature review, researchers proposed a number of routing protocols in WSN. In which cluster-based routing protocols shows better performance as compare to other routing protocols. Therefore, the objective of this paper is to provide a review on some efficient cluster-based routing protocols with advantages and limitations.

        Quantum Information Entropy and Entropy Squeezing of Isospectral Modified Hylleraas Plus Exponential Rosen Morse Potential and Isospectral Eckart Potential

        Pooja Thakur,Rama Gupta,Aarti Sharma,Anil Kumar 한국물리학회 2020 새물리 Vol.70 No.9

        We have numerically evaluated the position space and momentum space information entropy of the isospectral Modified Hylleraas plus exponential Rosen Morse potential and established that each level can be re-arranged as a function of the deformation parameter. The information densities of this potential have been graphically demonstrated and their properties thoroughly analyzed. An asymmetric shape dependence on the values of quantum number (n; l) is observed for the position space information densities. The characteristic features of the information entropy in position and momentum space have been analyzed, and the lower bound of the sum of the entropies, expressed by using the Bialynicki-Birula and Mycielski inequality is satisfied. Compared to undeformed potential exhibiting squeezing phenomena in momentum space only the information entropy squeezing has been realized for position space, as well as momentum space, as a function of the deformation parameter with the choice of the same set of parameters. Interestingly, squeezed coherent states are obtained for the isospectral Eckart potential.

        A comparative study of smica in various body fluids of diagnosed cervical cancer patients and healthy women

        ( Pooja A. Pachani ),( Rajendra R. Godbole ),( Jeevitaa Kshersagar ),( Rakhi Jagdale ),( Amita Gosavi ),( Somshekhar Patil ),( Rakesh K Sharma ),( Meghnad G. Joshi ) 대한산부인과학회 2022 Obstetrics & Gynecology Science Vol.65 No.1

        Objective Cervical cancer (CC) is a major public health problem in women, and its early detection can help reduce morbidity and mortality. The objective of this study was to compare serum levels of soluble major histocompatibility complex class I-related chain A (sMICA) levels in various body fluids between women diagnosed with CC and healthy women. Methods A case-control study was conducted at a tertiary care hospital and a cancer center in Kolhapur, India. Overall, 150 individuals (100 CC patients and 50 healthy women) participated after providing informed written consent. Demographic data, histopathology history, parity, and tumor, node, and metastasis (TNM) staging data were collected. Pap smears, saliva, blood, and urine samples were collected. Pap smears were examined microscopically, and sMICA levels in all samples were determined by enzyme-linked immunoassay (ELISA). Results The mean age of women with cervical cancer was 49.86±8.18 years. Squamous cell carcinoma (70%) was the most common histological variant in CC patients. Serum soluble sMICA levels differed significantly with parity and TNM staging (P<0.05). Mean levels of sMICA were significantly different in samples (CC cases vs. healthy patients; saliva: 166.721±108.718 vs. 0.039±0.005 pg/mL; urine: 82.921±45.580 vs. 0.010±0.005 pg/mL; serum: 35.756±10.799 vs. 0.039±0.005 pg/mL, P<0.001). Conclusion Levels of sMICA in body fluids can be considered as a diagnostic or prognostic tool to determine disease progression or tumor regression.

        An Improved Approach to Ranking Web Documents

        Pooja Gupta,Sandeep K. Singh,Divakar Yadav,A. K. Sharma 한국정보처리학회 2013 Journal of information processing systems Vol.9 No.2

        Ranking thousands of web documents so that they are matched in response to a user query is really a challenging task. For this purpose, search engines use different ranking mechanisms on apparently related resultant web documents to decide the order in which documents should be displayed. Existing ranking mechanisms decide on the order of a web page based on the amount and popularity of the links pointed to and emerging from it. Sometime search engines result in placing less relevant documents in the top positions in response to a user query. There is a strong need to improve the ranking strategy. In this paper, a novel ranking mechanism is being proposed to rank the web documents that consider both the HTML structure of a page and the contextual senses of keywords that are present within it and its back-links. The approach has been tested on data sets of URLs and on their back-links in relation to different topics. The experimental result shows that the overall search results, in response to user queries, are improved. The ordering of the links that have been obtained is compared with the ordering that has been done by using the page rank score. The results obtained thereafter shows that the proposed mechanism contextually puts more related web pages in the top order, as compared to the page rank score

        Comparison of Endoscopic and Histological Findings between Typical and Atypical Celiac Disease in Children

        Pooja Semwal,Raj Kumar Gupta,Rahul Sharma,Kapil Garg 대한소아소화기영양학회 2018 Pediatric gastroenterology, hepatology & nutrition Vol.21 No.2

        Purpose: Celiac disease is a common non-communicable disease with varied presentations. Purpose of this study was to find the duodeno-endoscopic features in celiac disease and to compare duodeno-endoscopic and histological findings between typical and atypical celiac disease in children. Methods: Hospital based observational study was conducted at Sir Padampat Mother and Child Health Institute, Jaipur from June 2015 to May 2016. Patients were selected and divided in two groups- typical and atypical celiac disease based upon the presenting symptoms. Upper gastrointestinal endoscopy and duodenal biopsy was per-formed for serology positive patients. Results were analysed using appropriate statistical test of significance.Results: Out of 101 enrolled patients, 47.5% were male. Age ranged from 1 to 18 years. Study showed that 54.5% were typical and 45.5% were atypical. Patients presenting with atypical symptoms were predominantly of older age group. On endoscopy, scalloping, mosaic pattern, reduced fold height and absent fold height; and in histology, ad-vanced Marsh stage were significantly higher in the typical group. Conclusion: Awareness of atypical presentations as well as duodeno-endoscopic features may have considerable practical importance for the diagnosis of celiac disease in children. Scalloping, mosaic pattern, reduced fold height and nodularity are main endoscopic markers of celiac disease in children. Endoscopic markers of duodenal mucosa may be important in early diagnosis of celiac disease, in children subjected to endoscopy for atypical presentations or indication other than suspected celiac disease.

        Prevalence of Sleep Disturbances During COVID-19 Pandemic in a Nepalese Population: A Cross-Sectional Study

        Avinash Chandra,Pooja Prakash,Nabina Sharma,Ayush Chandra 대한수면연구학회 2021 Journal of sleep medicine Vol.18 No.3

        Objectives: The coronavirus disease (COVID-19) pandemic and news of daily increasing cases inside Nepal and worldwide is adding to the fear that leads to anger, anxiety, frustration, and stress, emotions that directly affect sleep quality. This study aimed to assess sleep disturbances during the COVID-19 pandemic in a Nepalese population.Methods: This cross-sectional study recruited 206 Nepali residents who completed anonymous self-administered questionnaires. The Insomnia Severity Index (ISI) questionnaire was used to measure sleep disturbances before and after the COVID-19 pandemic. The gathered data were analyzed using descriptive statistics and inferential statistics using SPSS version 20 statistical software.Results: There was a significant variation in sleep disturbances among Nepalese residents before versus after the COVID-19 pandemic (p<0.001). The prevalence of clinical moderate insomnia has increased tremendously in Nepalese individuals. Before the pandemic’s onset, only 3.9% of the participants had moderate to severe levels of clinical insomnia; after its onset, this value increased to 17.5%. The mean ISI scores were 6.35±4.65 and 8.01±6.01 before and after the pandemic’s onset, respectively.Conclusions: Our study findings suggest that people are suffering tremendously with sleep disturbances and calls for further research and active measures to help increase sleep quality during the COVID-19 pandemic.
