It begins by offering a brief overview of the research history on quark-gluon plasma (QGP) and the corresponding research tool, heavy ion collisions. The paper mainly focuses on data analysis of a significant process within the hadronic collisions, namely, the charged-particle production. The investigation of this process is an integral part of QGP research, as it occurs promptly after the formation of QGP. By applying the tracklet method to the datasets collected by ALICE detector, an estimate of the charged-particle multiplicity density is presented. The finding then suggests a positive correlation between the number of participating nucleons in the collision and the normalized charged-particle multiplicity density. Notably, this dependence on centrality is similar to the research conducted by the ALICE collaboration, but derived from a distinct dataset. It indicates that there should be an underlying mechanism behind the intriguing phenomenological trend waiting for further exploration. These studies have the potential to enhance the understanding of quantum chromodynamics (QCD) and provide insights into the true nature of the universe.","PeriodicalId":341023,"journal":{"name":"Theoretical and Natural Science","volume":"28 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141800759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the multifaceted factors contributing to diabetes is pivotal for effective prevention strategies. In this study, we leverage a comprehensive dataset (952 instances, 17 predictor variables) and employ a multifaceted statistical approach to explore the intricate interplay among stress levels, blood pressure (BP), body mass index (BMI), age, sleep quality, and physical activity in relation to diabetes, with a focus on classification and predictive implications. Our research begins by establishing fundamental relationships between discrete variables using crosstabs and chi-square tests. We uncover close associations between stress levels and BP, heightened diabetes risk with increased BMI values, and the influence of age on sleep quality. Subsequent analysis, based on descriptive data, reveals a robust correlation between physical activity and stress levels, with the paradoxical observation that excessive exercise may increase stress levels. Factor analysis further elucidates the pivotal roles of sound sleep and regular exercise in diabetes prevention, supported by asymptotic significance levels below 0.05. To culminate our study, we construct a logistic regression model with an impressive 89.3% accuracy rate for predicting diabetes risk. Notably, age, family history of diabetes, and regular medication usage emerge as the most influential factors, with regular medication demonstrating significant potential for reducing diabetes risk. Our research underscores the intricate web of factors shaping individual health and offers valuable insights for a comprehensive understanding of health and well-being in the context of diabetes prevention. Moreover, it highlights the importance of considering multiple factors in health-related research. Future research could delve into the long-term effects of interventions targeting the identified risk factors, explore the impact of socio-economic factors on diabetes risk, and investigate the potential role of emerging technologies in personalized diabetes prevention strategies.","PeriodicalId":341023,"journal":{"name":"Theoretical and Natural Science","volume":"21 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141800952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Now, we are facing an energy crisis. Nuclear fusion has the advantages of cleanliness and efficiency, and has the potential to become our ultimate energy source. Nuclear fusion is a process in which two nuclei combine to form one nucleus, resulting in mass loss and energy generation. It requires high temperature, high pressure, and high density as reaction conditions. At present, people have achieved uncontrollable nuclear fusion - hydrogen bombs, and only controllable nuclear fusion can provide us with stable energy. The main technological routes of controllable nuclear fusion are inertial confinement fusion and magnetic confinement fusion, each with its own characteristics and facing its own problems. The development of controllable nuclear fusion is also constrained by issues such as how to achieving net energy gain and tritium self-sufficiency.

Due to neurotherapy and dysfunction of the immune system, impaired wound sensation is caused. Over time, such factors hinder wound detection and create a condition prone to infection and inflammation. Consequently, these wounds demand specialized interventions for successful resolution. Self-healing hydrogels appear as a solution, possessing the remarkable ability to autonomously repair damage sustained during use, mimicking the regenerative ability of native tissues. These advanced materials offer extensive benefits in wound management. Their rapid restoration of the structure upon mechanical disruption ensures prolonged contact with wound sites, maintaining an optimal healing environment. This review explores the current advances made in self-healing hydrogels as an effective and efficient biomaterial through their properties for addressing these challenges in diabetic wound treatment. With wound dressings playing an important role in promoting healing and preventing infections, this review focuses on self-healing hydrogels potential to revolutionize wound care practices.","PeriodicalId":341023,"journal":{"name":"Theoretical and Natural Science","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141801223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is one of the most prevalent and lethal cancers worldwide. Its cases and mortality rates vary significantly across different regions, reflecting differences in diet, genetics, and medicine access. Gastric cancer presents substantial challenges in medical treatment. The disease's complexity also leads to the exploration of various treatment methods. Among many pharmacological options, Fluorouracil and Docetaxel are two significant medicines that are worth discussing in depth. Fluorouracil and Docetaxel are both used in chemotherapy. However, they have distinct mechanisms and properties. Fluorouracil is a pyrimidine analog used to inhibit DNA synthesis of cancerous cells, while Docetaxel is a taxane that targets microtubules. They all played a vital role in treating cancer. Nevertheless, their comparative effectiveness and safety remain in debate.
