Nevertheless, the use of such a technology raises new challenges regarding the development of reliable and secure systems. Securing WSN is thus imperative and challenging. Unfortunately, he conventional security measures based on data encryption are not well suitable to WSNs due to energy and computational resource constraints. However, watermarking techniques usually have light requirements of resource. This approach is focused on ensuring integrity and authenticity of data. Moreover, in our approach watermark techniques is discussed. The proposed approach is implemented and simulated with the MatLab The simulation results show the comparative analysis energy efficient wireless sensor network.

Undiagnosed asymptomatic HCV sero-positive cases outnumber the diagnosed cases. Hypocoagulability because of hepatitis, can cause detrimental effect on cataract surgery. Objective: To analyze the cataract surgery complications in HCV infected cases. Methods: This was a prospective, observational study conducted in the department of Ophthalmology of Muzaffarnagar Medical College, Uttar Pradesh from January 2019 to January 2020. After taking permission from the ethical committee and informed-written consent from the patients, total 200 eyes of 158 patients having (116 unilateral and 42 bilateral) cataract and incidentally diagnosed positive for HCV infection were enrolled in the study.Results: Out of 200 eyes, 48 eyes had no complications and 152 (76%) eyes had one or more complications like intra...

Many institutions across the world and particularly in India have successfully developed their own IRs but have not attempted to assess their importance and impact on the Users. This study conveys the findings of the survey conducted at research centric CSIR (Council of Scientific and Industrial Research) laboratories of India to determine the scientists’ and research scholars’ preference for publishing their research materials; to measure the impact of IRs on their scholarly practices and to recommend future changes for inviting more participation in an IR. The study deduced that ‘PeerReview scholarly Journals’ are preferred medium for publishing research content and ‘Increase in the access to grey literature’ is the most significant impact of IR on respondents. The findings of this research paper provide insight to the IR m...

Any thyroid dysfunction can result in abortion, preterm labor or affects fetal neurodevelopment. Various anthropometric factors or genetic factors apart from iodine intake are known to affect the size of thyroid gland. Changes in thyroid gland morphology can be easily measured using ultrasonography as clinically the enlargement can be labelled as goiter. In this review, we aimed to evaluate the changes in thyroid gland during pregnancy and assess the different factors affecting its size across the various studies as the literature data concerning the thyroid gland enlargement during pregnancy is controversial. Various articles on thyroid volume changes during pregnancy from literature were reviewed along with a cross-sectional observation done in a government hospital setup in India, on 240 patients who were divided into...

Frequent spread of disease from sinonasal mucosa to bone, neck spaces, orbit, and brain occurs along the perivascular/perineural routes or through direct invasion. Brain involvement represents severe manifestation and is often associated with poor functional outcomes and high mortality rates. Magnetic resonance imaging (MRI) is the modality of choice for the intracranial assessment of disease severity in mucormycosis. Early and accurate identification of intracranial extension is imperative to improve survival rates. With this pictorial essay, we aim to familiarize the readers with the cross-sectional imaging features of intracranial complications of mucormycosis. The radiological details in this essay should serve as a broad checklist for radiologists and clinicians while dealing with this fulminant infection.

Although age-related, systemic, iatrogenic, and hormonal causes are more common and can be diagnosed by readily available lab tests, structural causes (either benign or malignant) are of concern to the patients in perimenopausal age women, when imaging (TVS, and MRI) comes into play. This study aims to compare the role of TVS and MRI in the characterization of uterine lesions presented as perimenopausal bleeding. Results: This observational prospective study was performed at a single tertiary care centre, comprising 52 consecutive patients of perimenopausal bleeding. All patients were subjected to TVS and MRI examination and correlation with histopathology was done. Most of the patients (44.2%) in our study belonged to age group of 40 to 49 years, with mean age for benign and malignant lesions was 46.81±8.5 and 52.10 ±7.05 r...

Ovarian lesions display a myriad of findings on imaging. Knowledge of these is essential to make a diagnosis or list the differentials. USG remains the mainstay imaging modality in this war on cancer. Aims & Objectives: To assess the diagnostic accuracy of USG B-mode and doppler in characterisation of ovarian mass lesions. Methods: 103 women with ovarian lesions were evaluated with USG B-mode and doppler. The interpretation was compared with histopathology reports wherever possible. Results: With sensitivity and NPV of 81.82% and 84.62% of USG B-mode, it is a good primary imaging modality. By showing an increase in specificity to 94.23%, PPV to 89.29% and accuracy to 87.06%, the addition of doppler in the evaluation acts as a tool in confirmation of malignancy. Conclusion: With good diagnostic performance, USG proves to be a good primary imaging modality. Also, doppler evaluation forms a promising add-on that can ...

High-density hot spots resulting from these power densities cause serious performance degradation or reliability issues, if not handled efficiently. Co-optimizing performance, power consumption, and the cooling capability can lead to enhanced performance without violating thermal constraints. This paper introduces a new EDA tool that facilitates co-design of highperformance processors with highly-efficient novel cooling techniques. The proposed tool is under-development and contains accurate thermal models of emerging cooling technologies such as liquid cooling, thermo-electric coolers, two-phase cooling, phase change material, or a hybrid cooling design. The planned tool is also capable of reducing simulation times by decoupling power/performance from thermal simulations. Further, we also plan to include several optimi...
