Mesothelioma is a form of cancer that is aggressive and fatal. It is a thin layer of tissue that covers the majority of the patient's internal organs. The treatments are available; however, a cure is not attainable for the majority of patients. So, a lot of research is being done on detection of mesothelioma cancer using various different approaches; but this paper focuses on optimization techniques for optimizing the biomedical images to detect the cancer. With the restricted number of samples in the medical field, a Relief-PSO head and mesothelioma neck cancer pathological image feature selection approach is proposed. The approach reduces multilevel dimensionality. To begin, the relief technique picks different feature weights depending on the relationship between features and categories. Second, the hybrid binary particle swarm optimization (HBPSO) is suggested to automatically determine the optimum feature subset for candidate feature subsets. The technique outperforms seven other feature selection algorithms in terms of morphological feature screening, dimensionality reduction, and classification performance. [ABSTRACT FROM AUTHOR]

Forest fires due to pine needles in the northwestern Himalayas during summers are a very common phenomenon every year causing major harm to flora and fauna. They are a major contributor to climate change as forest fires destroy hectares of land covered by forest and emit greenhouse gases in the atmosphere. One possible solution to this problem is to generate energy from the bio residue of pine tree. This paper intends to identify, categorize and prioritize the major factors that hinders and are barriers to energy generation using pine needles in the state of Uttarakhand, India. This paper adopts a multi-criteria decision-making approach based on the technique of fuzzy Analytical Hierarchy Process. Sensitivity analysis is also used to test the robustness of this technique. The study finds that Legal and regulatory factors are the most critical and categorized as major influences of such renewable energy generation project, which includes government policy, project guidelines, financial support, technical support, and government clearances. The second barrier is economic which majorly includes cost factor associated with the development and sustenance of such energy generation projects. Technological and market related factors are next on the priority to energy generation using pine needles through limitations such as topography, hilly terrain, seasonal availability, supply chain, poor marketing. Human resource barriers stands at the fifth place and has less influence on such energy generation initiatives. This paper will help the policy makers to understand the priorities while solving energy generation issues to reduce forest fires and contribute to mitigate climate change. • To categorize the major factors negatively affecting energy generation using Pine needles. • To assess and prioritize these barriers. • To deliver managerial and practical implications for these barriers. • Legal and regulatory most critical barrier to pine needle based energy generation. • Lack of proper marketing has topmost global ranking as barrier.
