Cryptographic Interweaving of Messages
During the past several decades, the information and communication technology sector has advanced significantly, enabling extensive information interchange over the internet, including message sharing and electronic transactions. These days, the main issue is how to transmit information securely. From ancient times, there has been interest in the field of cryptography research. A masterwork of cryptography is Muni Kumudendu's original work, Siribhoovalaya. His study served as the basis for the method suggested in this publication. Several messages can be sent using different keys utilising a single matrix. Encryption uses a variety of matrix traversal techniques, making it challenging for cryptanalysis to map the plaintext and ciphertext
Evaluation of the wound healing effect of Jasminum grandiflorum by wound contraction studies and wound breaking strength
Background: Wound is a common process leading to inflammation and healing process. Jasminum grandiflorum is a plant widely grown in Karnataka and is mention in ancient medical systems to promote healing. So the study was taken up to confirm the anti-inflammatory effect of the plant.Methods: Excision and incision wound models in albino rats were used to study the wound healing effect. It was mainly studied by the degree of epithelisation at various intervals and compared with control group. The strength of the wound was assessed by its wound breaking strength at the end.Results: It was found that jasmine extract increased the degree of epethelisation and thus promoting wound healing. It was also found that the wound breaking strength was more in the drug treated group compared to normal.Conclusions: Jasminum grandiflorum leaf extract is known to have wound healing property. Â

NIT COVID-19 at WNUT-2020 Task 2: Deep Learning Model RoBERTa for Identify Informative COVID-19 English Tweets
This paper presents the model submitted by the NIT_COVID-19 team for
identified informative COVID-19 English tweets at WNUT-2020 Task2. This shared
task addresses the problem of automatically identifying whether an English
tweet related to informative (novel coronavirus) or not. These informative
tweets provide information about recovered, confirmed, suspected, and death
cases as well as the location or travel history of the cases. The proposed
approach includes pre-processing techniques and pre-trained RoBERTa with
suitable hyperparameters for English coronavirus tweet classification. The
performance achieved by the proposed model for shared task WNUT 2020 Task2 is
89.14% in the F1-score metric.Comment: 5 pages, one figures, conferenc
Identifying Implementation Bugs in Machine Learning based Image Classifiers using Metamorphic Testing
We have recently witnessed tremendous success of Machine Learning (ML) in
practical applications. Computer vision, speech recognition and language
translation have all seen a near human level performance. We expect, in the
near future, most business applications will have some form of ML. However,
testing such applications is extremely challenging and would be very expensive
if we follow today's methodologies. In this work, we present an articulation of
the challenges in testing ML based applications. We then present our solution
approach, based on the concept of Metamorphic Testing, which aims to identify
implementation bugs in ML based image classifiers. We have developed
metamorphic relations for an application based on Support Vector Machine and a
Deep Learning based application. Empirical validation showed that our approach
was able to catch 71% of the implementation bugs in the ML applications.Comment: Published at 27th ACM SIGSOFT International Symposium on Software

Thought control study of medical students in Shimoga Institute of Medical Sciences (SIMS)
Background: Thought is a mental process which occurs in the Neo-cortex of the Brain [Cerebral cortices] based on the background knowledge, perception of the event or the action and understanding influenced by the individual traits or personality. Individual thoughts differ from person to person, time to time, and the events in life. Mainly thought is interpreted or understood based on the behaviour or when the person explains about it. Thought process in the brain can be acknowledged by an individual to have acceptable behavioural norms in the society, but cannot be explained by patients with disorder of thought processes. The behaviour of these individuals is acknowledged as the thought of the individual. Abnormal thought process occurs in psychiatric conditions like Psychosis, Anxiety disorder, Post traumatic disorder, mood disorders in varied manners. It also has implications or influences of the hormonal status and age of the person. In this study we are evaluating the thought control in the teenagers.Methods: the study was carried out in the medical students of SIMS-Shimoga. It is a questionnaire based study using a thought control questionnaire (TCQ).Results: The results were studied in five domains namely Distraction, Social, Worrying, Punishment and Re-appraisal, were found to vary within the acceptable limits and comparable with earlier studies.Conclusion: The findings in this study reflect the positive approach, handling of the unwanted and distracting thoughts in the teenagers.
Catalysis and mechanistic studies of ruthenium and osmium on synthesis of anthranilic acids
Ruthenium, osmium and ruthenium + osmium catalyzed synthetic methodology was developed for the synthesis of anthranilic acids from indoles in good to excellent yields using bromamine-B in alkaline acetonitrile-water (1 : 1) at 313 K. Detailed catalysis studies of ruthenium, osmium and the mixture of both were carried out for the synthetic reactions. The positive synergistic catalytic activity of Ru(III) + Os(VIII) was observed to a large extent with the activity greater than the sum of their separate catalytic activities. Detailed kinetic and mechanistic investigations for each catalyzed reactions were carried out. The kinetic pattern and mechanistic picture of each catalyzed reaction were found to be different for each catalyst and to obey the underlying rate laws

Background: Avulsion fractures of tibial insertion of the posterior cruciate ligament are rare among the knee injuries. Purpose of this study is to determine the functional outcome of arthroscopic reattachment of tibial avulsion of the Posterior cruciate ligament by ABS button (Arthrex) and tight rope.Methods: 15 Patients with PCL avulsion fracture were included. The Inclusion criteria were: 1) Displaced avulsion fractures (type-2 and type-3). They were followed at regular intervals using IKDC score, Lysholm score and subjective questionnaire.Results: All cases showed complete osseous union during follow up. All knees are stable on examination by posterior sag sign and posterior drawer test. Two patients had loss of about 100 flexion. According to the IKDC form assessment 13 patients classified as normal and 2 were classified as near normal.Conclusions: Arthroscopic reattachment of tibial avulsion fractures of the posterior cruciate ligament using ABS button and tightrope gives fairly good clinical outcomes.
Study on self-medication among 2nd year medical students
Background: Self-medication is use of medicines by individuals to treat self-recognized symptoms and illness. Self-medication is a common type of self-care behavior in the general public, but medical students differ in such practice, as they have knowledge about drugs and diseases.Methods: The present study involved 100 2nd year final term medical students in “Shivamogga Institute of Medical Sciences,” Shivamogga, Karnataka. Study was questionnaire based, and the results were analyzed by descriptive statistical methods.Results: In our study, 57% were female, and 43% were male. About 60% had knowledge about over the counter (OTC) drugs and considered Ayurveda drugs also OTC drugs. 25% considered self-medication entirely safe, whereas 61% considered self-medication have advantages. Self-medication was preferred by 72% as they felt that there is no need to consult health care professionals for a simple ailment. Self-medication was practiced by 62% students, among which 86% were appropriate, and 48% among them utilized knowledge from previous consultation. In 28% fever was the most common condition and paracetamol was the most commonly used drug.Conclusions: Self-medication was widely practiced among the students. They had good knowledge of OTC drugs. The practice of self-medication was almost appropriate. In general self-medication must be accompanied by appropriate information. Educating benefits and risks of self-medication is very much needed for medical students and the public now a day
