Theoretical and Natural Science

- The Open Access Proceedings Series for Conferences

welcome Image

The proceedings series Theoretical and Natural Science (TNS) is an international peer-reviewed open access series which publishes conference proceedings from a wide variety of disciplinary perspectives concerning theoretical studies and natural science issues. The series publishes articles that are research-oriented and welcomes theoretical articles concerning micro and macro-scale phenomena. Proceedings that are suitable for publication in the TNS cover domains on various perspectives of mathematics, physics, chemistry, biology, agricultural science, and medical science. The series aims to provide a high-level platform where academic achievements of great importance can be disseminated and shared.

    Accurate segmentation for Functional Tissue Units (FTUs) is a challenging issue in past decades. In this study, a model using the dataset of tissue section images will be built to evaluate and mark FTUs across five human organs as clearly as possible. We have the Human Protein Atlas (HPA) as training data and the data from Human BioMolecular Atlas Program (HuBMAP) as testing data. To balance accuracy and inference speed, this study applied Unext, an efficient network based on Unet, as the basic model. We also aim to use some tricks to further improve the performance of the model. First, we used several image enhancement methods to diversify the input image. Second, several structures like Feature Pyramid Network (FPN) and the Atrous Spatial Pyramid Pooling are added to improve model performance and convergence speed. As a result, we successfully segment functional tissue units among images of different sizes. Our proposed model scored 0.56 out of 1.00 by the judge of the competition.

    Alzheimer's disease is one of the most common neuropsychiatric disorders in the elderly. The disease has a long course and brings a heavy burden to individuals, families and society, and there is no clinical cure for it. Currently, in families, family members often act as caregivers to take care of patients with Alzheimer's disease. Past studies have examined the care patterns, roles, strategies, and influence of family caregivers on Alzheimer's patients. However, there is little literature review to understand the care mode, effect and influence of family caregivers on Alzheimer's patients. Therefore, this study sorted out and recognized the impact and the role of current family caregivers' interventions on Alzheimer's patients. A range of intervention strategies and models employed in family care are included as well. It was shown that family caregivers can effectively alleviate the cognitive decline of Alzheimer's patients through cognitive-related intervention models and can help them return to normal life.

    Food production is an important factor in causing environmental pollution, and the processing of food contamination information data, classification, and ultimately rating of the degree of food contamination is an important way to recognize food contamination. Rating the environmental friendliness of food can help people to choose more environmentally friendly food in their daily life and allow companies, scholars, and research organizations to recognize which food can be reduced by technological advances. This study focuses on the contamination rating of foods that are most referenced to help scholars and people understand the environmental contamination capabilities of different foods. This study focuses on the different foods in the Kaggle data, and their contamination aspects of the data were processed. The study began with the classification of foods. This study uses data from Kaggle on various environmental pollutants of food. It uses the linear regression model in the R Studio to select the most suitable pollution objects for evaluation. Finally, this study scored different foods according to different contamination aspects and obtained the following results: 1) detailed food scoring graphs, 2) animal-based food has a greater total contamination capacity than plant-based food.

    As a non-renewable energy source, oil has an unshakable position in the development of human beings. Still, no one has noticed that the oil buried deep in the ground is also inextricably linked to the birds flying in the air. This article focuses on how oil, except diet, has been linked to bird deaths. The first research direction is to study the feather structure and function of birds. It is concluded that oil will damage the functionality of feathers and make the feathers of birds unable to function. The second research direction is about the inversely proportional relationship between the flight speed of birds and oil and the directly proportional relationship between energy consumption and oil. It is concluded that oil will affect the speed and energy consumption of birds and make birds more vulnerable to predation by natural enemies. The third research direction is the analysis of the damage degree of oil to birds' eggs and young. Based on these studies, it is possible to find out feasible methods that can effectively reduce the harm of oil extraction operations to birds without affecting normal human activities. Let birds have a way to reproduce healthily and safely without hindering human development.
