This study highlighted the role of consumers' characteristics and their association with social experience in Social Commerce (SC) usage. A theoretical model was developed using Social Exchange and Social Impact theory to disclose the factors influencing user intention in SC by made use of 532 Indonesian respondents. The results showed that the social experience factors were discovered to have enhanced individual personal constructs associated with SC intention, including Habit, Self-efficacy, and Trust. In detail, Perceived Herd and Informational Support were found to have both direct and indirect impacts on user intention through individual personality characteristics. In contrast, Emotional Support has only an indirect effect. Even though prior studies already observe constructs proposed in the theoretical model, the exploration of the extensive association between social experience on the personal element concerning individual intention to use SC has not been adequately addressed. Therefore, it is considered as a contribution of this study toward the body of knowledge.

This paper proposes a new training algorithm for artificial neural networks based on an enhanced version of the grey wolf optimizer (GWO) algorithm. The proposed model is used for classifying the patients of diabetes disease. The results showed that the proposed training algorithm enhanced the performance of ANNs with a better classification accuracy as compared to the other state of art training algorithms for the classification of diabetes on publicly available “Pima Indian Diabetes (PID) dataset”. Several experiments have been executed on this dataset with variation in size of the population, techniques to handle missing data, and their impact on classification accuracy has been discussed. Finally, the results are compared with other nature-inspired algorithms trained ANN. EGWO attained better results in terms of classification accuracy than the other algorithms. The convergence curve proved that EGWO had balanced the local and global search abilities because it was faster to reach better positions than the original GWO.

Cardiac Magnetic Resonance Imaging is a popular non-invasive technique used for assessing the cardiac performance. Automating the segmentation helps in increased diagnosis accuracy in considerably less time and effort. In this paper a novel approach has been proposed to improve the automated segmentation process by increasing the accuracy of segmentation and laying focus on efficient pre-processing of the cardiac Magnetic Resonance (MR) image. The pre-processing module in the proposed method includes noise estimation and efficient denoising of images using discrete total variation based Non local means method.Segmentation accuracy is evaluated using measures such as average perpendicular distance and dice similarity coefficient. The performance of all the segmentation techniques is improved. Further segmentation comparison has also been performed using other state-of-the art noise removal techniques for pre-processing and it was observed that the proposed pre-processing technique outperformed other noise removal techniques in improving the segmentation accuracy.

The novel Corona virus SARS-CoV-2 has started with strange new pneumonia of unknown cause in Wuhan city, Hubei province of China. On March 11, 2020, the World Health Organization declared the COVID-19 outbreak as a pandemic. Due to this pandemic situation, the countries all over the world suffered from economic and psychological stress. To analyze the growth of this pandemic, this paper proposes a supervised LSTM model and its variants to predict the infectious cases in India using a publicly available dataset from John Hopkins University. Experimentation has been carried out using various models and window hyper-parameters to predict the infectious rate ahead of a week, 2 weeks, 3 weeks and a month. The prediction results infer that, every individual in India has to be safe at home and to follow the regulations provided by ICMR and the Indian Government to control and prevent others from this complicated epidemic.

Based on iceberg theory and the questionnaire of competency’s elements, hierarchical index system of evaluation of teachers' innovation and entrepreneurship competency in universities is established. Through researches, we think that analytic hierarchy process(AHP) is a more scientific and reasonable evaluation method whose rationality is checked by satisfactory consistency while the evaluation model of artificial neutral network doesn’t consider weighting. If the samples are more than 30, the evaluation of neural network model of teachers' innovation and entrepreneurship competency can achieve the accurate results and satisfactory requirements. Since the method of artificial neutral network has advantages of strong operability, simple rules and minor errors, it can greatly reduce the workload because it not only eliminates human subjectivity of evaluation and greatly simplifies the process of evaluation, but also improves working efficiency and provides a new way of thinking for evaluation of the teachers' innovation and entrepreneurship competency in universities

It is necessary to systematically review the literature since the information and communication technology (ICT) assisted flipped pedagogical approach in English education has been increasingly popular. By way of visualization through CiteSpace and other qualitative research methods, we arrived at the conclusion that most of the studies support the ICT-assisted flipped pedagogical approach in EFL education although there are still some different findings. The flipped classroom pedagogy in EFL education may bring many advantages to students, teachers, and researchers. Disadvantages of the ICT-assisted flipped pedagogical approach include difficulty in supervising students’ learning activities, organization of in-class academic activities, cautious attitudes, and some negative learning outcomes. We also explored the number of recent publications and citations, co-citation clusters of the cited literature, citation counts, and rankings by bursts, centrality, and sigma. Future research may focus on the interdisciplinary research into the ICT-assisted flipped pedagogical approach.

A novel method for integrating multi-omics data, including gene expression, copy number variation, DNA methylation, and miRNA data, is proposed to identify biomarkers of cancer prognosis. First, survival analysis was performed for these four types of omics data to obtain survival-related genes. Next, survival-related genes detected in at least two types of omics data were selected as candidate genes. The four types of omics data only composed of candidate genes were subjected to dimension reduction using an autoencoder to obtain a one-dimensional data representation. The mRMR algorithm was used to screen for key genes. This method was applied to lung squamous cell carcinoma and 20 cancer-related genes were identified. Gene function analysis revealed that the genes were related to cancer. Using survival analysis, the genes were verified to distinguish between high- and low-risk groups. These results indicate that the genes can be used as biomarkers for cancer.
