In nested hierarchies in the brain, consciousness is a confluence of wakefulness, arousal, and awareness. Disorders of consciousness, such as the Unresponsive Wakefulness Syndrome (UWS), present profound challenges in the medical domain. UWS patients experience severe disturbances in awareness and reactivity, often due to traumatic or non-traumatic brain injuries. Central to the debate on consciousness is the thalamus, a neural relay pivotal to cognitive function. Recent research emphasizes the thalamuss role in disorders like UWS, particularly when stemming from thalamic injuries. Novel thalamic interventions, like Deep Brain Stimulation (DBS) and Stereotactic Thalamotomy, have been explored for therapeutic potential, showing varying outcomes. The transition towards targeted thalamic treatments, underscored by advanced imaging insights, marks a shift in UWS therapeutic strategies. However, the intricacies of the thalamus and the heterogeneity of UWS necessitate a comprehensive and individualized approach. As researchers delve deeper, the thalamus stands central to potential breakthroughs in restoring consciousness in UWS patients.","PeriodicalId":341023,"journal":{"name":"Theoretical and Natural Science","volume":"34 44","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141800482","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}

Here, we used publicly available data on air pollution and breast cancer incidence to investigate the impact of industrialization on the development of breast cancer in the county. This paper used three air pollutants, carbon monoxide, ozone, and nitrogen dioxide, as indicators of the industrialization of counties. The study covered 135 counties from 2015 to 2019. Through statistical analysis and related evaluation, the relationship between the industrialization index and breast cancer incidence and regional distribution was discussed. The ecological design of the study limits the establishment of causality at the individual level. Limitations of the study include considering only three air pollutants as a proxy for industrialization and not taking other potential breast cancer risk factors into account. The results of this study contribute to the existing papers on environmental factors associated with breast cancer risk and have implications for public health and policymaking. Key areas for future research include exploring other pollutants, addressing limitations in study design, and considering other potential risk factors for breast cancer incidence.","PeriodicalId":341023,"journal":{"name":"Theoretical and Natural Science","volume":"13 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141801002","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}

Amidst the physiological and psychological transitions characteristic of adolescence, there is a heightened risk of depressive disorders. These shifts, coupled with the dynamic nature of their online expressions, create a compelling case for detecting latent signs of depression within their digital footprints. This thesis delves into the intersection of Natural Language Processing (NLP) and adolescent depression detection, introducing an innovative hierarchical ensemble model tailored for the intricate task of identifying depressive markers in adolescent social media content. This model amalgamates traditional word embeddings with state-of-the-art pretrained models, encapsulating both sentence-level and word-level representations. Empirical validation, conducted on a unique dataset centered on adolescent depression detection, indicates the models superior efficacy over existing baselines. By offering an ensemble approach that captures the nuances of adolescent linguistic expressions, this research illuminates the potential for timely and non-intrusive interventions in adolescent mental health.","PeriodicalId":341023,"journal":{"name":"Theoretical and Natural Science","volume":"13 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141801105","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}

Its synthetic structure and broad range in absorption has made it harmful to both tumor and healthy cells and tissues. The study aims to see whether a natural and herbal extract like Chlorophyllin, used in primarily bladder cancer, can become an alternative to Verteporfin. Methods: This study uses HSC-2 cell lines and mice models. The cancer cells in vitro and in vivo will be treated with increasing amounts and various durations of Chlorophyllin and Verteporfin. Killing in vitro is measured by MTT assay and in vivo is measured by xenograft tumor size. Positive control is Verteporfin, and negative control is DMSO in vitro or saline solution for the xenograft experiment. Possible results: The three main possible results: (1) Chlorophyllin kills more cancer cells in vitro and in vivo and it has less killed normal tissue. (5) Verteporfin kills more cancer cells but also has more damage to normal tissues when compared to Chlorophyllin. (8) Verteporfin kills more cancer cells in vitro and in vivo and it has less killed normal tissue. Conclusion: The results of the study will determine if natural alternatives are worth investing research into as they can be low-cost extraction, low toxicity, and high selectivity of cells to kill. Chlorophyllin can pave the way to more intensive research of natural photosensitizers in different types of cancers.","PeriodicalId":341023,"journal":{"name":"Theoretical and Natural Science","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141801559","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}

In this paper, we consider the length of strictly monotone factorization from the perspective of Cayley graph theory. We represent the factorization problem using a Cayley graph, where vertices are permutations and edges are transpositions. Our focus is proving the unique monotone factorization theorem, which states that for a given permutation, there is only one monotone factorization of minimal length. To prove this, we employ inductive arguments on the structure of the Cayley graph. The key insight is using the connectivity of the graph and properties of shortest paths to characterize the uniqueness of the minimal factorization. This inductive approach allows us to rigorously connect the combinatorial Hurwitz problem to foundational graph concepts. Overall, this paper makes important theoretical advances in enumerating Hurwitz numbers by using Cayley graphs and induction to prove the novel unique monotone factorization theorem. The connections drawn between combinatorics, graphs, and inductive proofs are technically innovative. This theoretical foundation will hopefully stimulate further research into the deep links between the Hurwitz problem and other branches of mathematics.","PeriodicalId":341023,"journal":{"name":"Theoretical and Natural Science","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141801864","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}
