Segmentation and feature extraction of fluid-filled uterine fibroid–A knowledge-based approach

Uterine fibroids are the most common pelvic tumours in females. Ultrasound images of fibroids require image segmentation and feature extraction for analysis. This paper proposes a new method for segmenting the fluid-filled fibroid found in the uterus. It presents a fully automatic approach in which there is no need for human intervention. The method used in this paper employs a number of knowledge-based rules to locate the object and also utilises the concepts in mathematical morphology. It also extracts the necessary features of the fibroid which can be used to prepare the radiological report. The performance of this method is evaluated using area-based metrics

Moral Principles in the Politics of Kings in Puranaanooru

A man should always act with good intentions. It is good thoughts and virtuous actions that ultimately bring good to a person. Realizing this, the scholars guided the kings with the help of the tool of knowledge. Apart from that, they paved the way for the blossoming of virtuous thoughts in the minds of the kings and the establishment of good governance. And the Purananooru suggests that the poets imparted to the rulers the moral principles that a king should protect his subjects like a mother who protects her child with little self-interest. Poets highlighted many morals to make society in good order during the Sangam period. When the king failed to perform his duty in political rule and deviated from the principles to be followed in war, even if he had forgotten charity, the Sangam poets are credited with advising the kings in a proper manner and changing their rule in a righteous way, even if they had not shown mercy to the enemy. Even the kings who listened to the pious thoughts of the poets are worthy of admiration even today. Many of the works that propose the superiority of Tamil are among the works that guide the norms that are followed even today. Even though it is a book that talks about Purananooru war stories and bad news, it takes all the principles of human life. The rule of the kings led to the happiness of the people. The ancient Tamil kings were not only brave but full of courage, and the purpose of this article is to investigate the political principles and practises followed by the kings during their reign

Malware Detection Using Tlenet On Image Data

The prevalence of malicious software is referred to as malware and has seen a notable increase today. It is a significant threat to the overall integrity of internet security in modern time is significant. Malware is a dangerous threat to the whole internet users due to its unauthorized data acquisition and inflict damage upon computer systems. Malware detection has gathered a significant attention within academic fields due to the growing prevalence of malware. Threats pose risks to the individual computer users, corporations and governmental entities, etc., to detect the unidentified malware in real-time is difficult. The malware detection systems depend on the examination of the malware signatures and behavioral patterns is by the combination of dynamic and static analysis.  The problem is to identify and categorise the malicious software by image analysis techniques. Deep learning (DL) are used for image recognition after the conversion of executable files into image formats in the mailimg and ImageNet datasets. Transfer learning is used to train deep learning models for large-scale datasets. The problem within this method is slow and laborious. In pursuit of the objective, the study investigates the implementation of deep convolutional neural networks to classify the malware. Additionally, it provides methodologies for effectively using transfer learning techniques to compromise the challenges associated with detecting and categorizing the different types of malware. To enhance the classification of malware, a pre-trained convolutional neural network (CNN) in transfer learning is used to categorize the malware images from the Malimg and ImageNet datasets are proposed. The Malimg dataset consists of malicious programs in the form of images are classified using the portable executable files. EfficientNet3 classifier has scored an impressive accuracy of 99.60 percentage

ROLE OF VITAMIN C AND VITAMIN E ON HYPERTENSION

Objective: Both Vitamin C and Vitamin E supplementation were associated with reduction in blood pressure (BP) in observational studies, although, results of clinical trials are inconsistent. The objective of our study is to conduct a clinical trial to observe the effects of oral supplementation of Vitamin C and Vitamin E on BP. Methods: About 60 non-teaching staffs of our college with systolic BP more than 130 mmHg and diastolic BP more than 90 mmHg were taken as subjects and divided into two groups. Initial BP and BP after oral Vitamin C, 500 mg/day for a period of 12weeks to Group 1 and initial BP and BP after oral Vitamin E, 200 IU/day, for a period of 12 weeks to Group 2 were recorded. Results: Statistical analysis was done by paired t-test, analysis of variance (ANOVA), and least significant difference (LSD) tests. *p<0.05 was considered statistically significant. Systolic 2 and diastolic 2 – after 3 months of supplementation showed 0.161 and 0.161 which is not significant. ANOVA and LSD tests show no significant results. Conclusion: Long-term trials on the effects of Vitamin C and Vitamin E supplementation on BP and clinical events are needed

Comparative evaluation of antimicrobial efficacy of various phytochemical irrigants and 3% sodium hypochlorite against an endodontic biofilm model and scanning electron microscopic observation of surface morphology of root canal dentin after treatment with different irrigants: An Ex Vivo study

AIM OF THE STUDY: To determine the optimum concentration of herbal extracts namely Acacia nilotica (Babool), Azadirachta indica (Neem), Cinnamomum zeylanicum (Cinnamon), and Syzygium aromaticum (Clove) for their antimicrobial activity and to test the efficacy of herbal irrigation against 3% Sodium Hypochlorite, together with instrumentation in the removal of multispecies endodontic biofilm. MATERIALS AND METHODS: Ethanolic extract of A.nilotica, A.indica, C.zeylanicum and S.aromaticum was prepared and the susceptibility of mixed microbial strain to different antibiotics Vs herbal extracts was tested using well diffusion method to determine the optimum concentration of the extract. Sixty single-rooted human mandibular premolars were decoronated, prepared and randomly grouped into five groups consisting of 12 teeth each. Two teeth in each group were selected and prepared for viewing under Scanning Electron Microscope (SEM) after the irrigation protocol. Group I – conventional irrigation consisting 3% Sodium Hypochlorite (NaOCl), Group II – irrigation with Acacia nilotica extract, Group III – irrigation with Azadirachta indica extract, Group IV – irrigation with Cinnamomum zeylanicum extract, Group V – irrigation with Syzygium aromaticum extract. All the prepared teeth were sterilized and the canals were inoculated with mixed human subgingival plaque bacteria and incubated at 37ᵒC for 24 hours to allow the biofilm to form. The teeth specimens were treated with the various irrigants to be tested and the antibacterial efficacy of the herbal extracts compared to NaOCl was evaluated by Culture Study (Colony Counting) and Turbidity Testing (Optical Density at 600nm). RESULTS: The results showed that complete elimination of bacteria was not achieved in any of the experimental groups. The best antibacterial activity through Optical Density was shown by Group I, followed by Group II and the least by Group III. The best antibacterial activity through Colony Counting was shown by Group I, followed by Group II and the least by Group V. Scanning Electron Microscopy analysis showed moss like depositions on the dentin surface in Group IV and V and mat like depositions in Group I and II, whereas dentin surface in Group I showed relatively clear dentinal surface with patent dentinal tubules. CONCLUSION: Within the limitations of this study, 3% sodium hypochlorite showed maximum antibacterial activity, followed by Acacia nilotica which showed almost similar results. The use of herbal alternatives as a root canal irrigant might prove to be advantageous considering the several undesirable characteristics of Sodium Hypochlorite. Further research is needed to overcome the deposition of extracts on the dentin surface and conclusively recommend herbal solutions as root canal irrigants

Multi-Biometric System Based On The Fusion Of Fingerprint And Finger-Vein

Biometrics is the process of measuring the unique biological traits of an individual for identification and verification purposes. Multiple features are used to enhance the security and robustness of the system. This study concentrates exclusively on the finger and employs two modalities - fingerprint and finger vein. The proposed system utilizes feature extraction for finger vein and two matching algorithms, namely ridge-based matching, and minutiae-based matching, to derive matching scores for both biometrics. The scores from the two modalities are combined using four fusion approaches: holistic fusion, non-linear fusion, sum rule-based fusion, and Dempster-Shafer theory. The ultimate decision is made by the performance metrics and the Receiver Operating Characteristics (ROC) curve of the fusion technique with the best results. The proposed technique is tested on images collected from the "Nanjing University Posts and Telecommunications- Fingerprint and Finger vein dataset (NUPT-FPV)." According to the results, which were obtained for 840 input images the proposed system accomplishes the Equal Error Rate (EER) of 0% while using Dempster Shafer-based fusion and 14% while using the other three fusion techniques. Also, the False Acceptance Rate (FAR) is very low at 0% for all the fusion techniques which are crucial for security and preventing unauthorized access
