Prevailing neural approaches have made significant strides in relation extraction by representing sentences in compact, low-dimensional vectors. However, the incorporation of syntactic nuances when modeling entities remains underexplored. Our study introduces a novel method for crafting syntax-aware entity embeddings to boost neural relation extraction. We start by encoding entity contexts within dependency trees through tree-GRU to generate sentence-level entity embeddings. We then apply both intra-sentence and inter-sentence attention mechanisms to distill entity embeddings at the sentence set level, considering every occurrence of the pertinent entity pair. The culmination of our methodology is the fusion of sentence and entity embeddings for relation classification. Our experiments on a benchmark dataset indicate that our approach harnesses the full potential of informative instances, thereby setting new benchmarks for relation extraction performance.","PeriodicalId":500086,"journal":{"name":"Research Square (Research Square)","volume":"9 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136228770","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}

Many serial algorithms have been developed to solve CTSP instances. This work presents a distributed solving method for CTSP for the first time. First, a cloud container-based distributed solving framework for CTSP is designed and implemented in a pipeline style. A superscale CTSP can be decomposed into many TSPs to solve in parallel to reduce computational complexity dramatically. Second, following the framework, we develop a distributed Delaunay-triangulation-based variable neighborhood search (DDVNS) algorithm. In DDVNS, a two-stage initialization is exploited to generate each TSP solution. Then, Delaunay-triangulation-based variable neighborhood search (DVNS) is applied to search for the local TSP optima within a neighborhood delicately. In addition, the solutions are improved further by reallocating the multicolor cities and repeating the search progress. Finally, the extensive experiments show that DDVNS outperforms the state-of-the-art serial algorithms regarding search efficiency and solution quality. Notably, We can achieve a satisfactory solution in a superscale case of 16 salesmen and 160000 cities within 15 minutes, which breaks the existing solving record of CTSPs.","PeriodicalId":500086,"journal":{"name":"Research Square (Research Square)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136229344","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}

The conceptual framework is based on the null hypothesis which states that there is no relationship between implementing artificial intelligence in healthcare and doctor’s redundancy. Having used the 2-tailed One-Sample T-Test to test that hypothesis on IBM SPSS, in order to successfully reject the hypothesis, and present an alternatively more accurate hypothesis that is more accurately representative. Additionally, DICE framework has also been presented in order to calculate the success/failure likelihoods of implementing artificial intelligence in healthcare. We conclude that artificial intelligence significantly impacts cost reduction in the long term, as well as only ever displacing behind-the-curve doctors who are unwilling to broaden their knowledge and develop their skills. Finally, we conclude that people’s resistance to change significantly affects the efficient and effective implementation of artificial intelligence in healthcare.","PeriodicalId":500086,"journal":{"name":"Research Square (Research Square)","volume":"2 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136229207","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}

For decades, it has been known that female tissue is less sensitive to AKI 4,5 , but the underlying mechanisms have remained elusive. As a specific feature, ATN is characterized by dynamic cell death propagation along the tubular compartment, mediated by ferroptosis in male mice 6,7 . Herein we demonstrate that ferroptotic cell death propagation is abrogated in female kidney tubules. Ferroptosis sensitivity in females was decreased by estradiol and its derivatives, which function as radical-trapping antioxidants (RTAs). Female sex-specific tubular expression of ferroptosis suppressor protein 1 (FSP1, also AIFM2) functions to regenerate the estradiol derivatives from their oxidation products, thereby potentiating RTA capacity. In addition, females exhibited much higher levels of anti-ferroptotic hydropersulfides detected directly from the most sensitive tubular compartment. In contrast, male proximal tubules express alkylglycerone phosphate synthase (AGPS) and fatty acyl-CoA reductase 1 (FAR1), key enzymes required for the generation of ether lipids which sensitize to ferroptosis. In summary, we uncover three independent mechanisms that collectively explain higher ferroptosis sensitivity of male over female tubular tissue and may function as therapeutic targets.","PeriodicalId":500086,"journal":{"name":"Research Square (Research Square)","volume":"2 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136229210","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}

Recent advancements have considerably enhanced its effectiveness. However, a gap remains in these systems' ability to fully leverage the recursive dynamics of linguistic structures. This study introduces a novel approach, intertwining the recognition of entities with a deeper understanding of linguistic syntax and tree-like structures. Utilizing a Tree-LSTM that operates under the guidance of dependency trees, we capture the intricate syntactic relationships between words. This process is further refined through the dual application of relative and global attention mechanisms. The relative attention zone is on critical words in the context of each evaluated word, whereas global attention identifies keywords throughout the entire sentence. By projecting these attention-modulated features into a tagging space, our model employs a conditional random field classifier to determine entity labels. We discover that our model adeptly highlights verbs that reveal the types of entities, influenced by their syntactic roles within sentences. Our model sets a new benchmark for performance on two prominent datasets, substantiating our approach.","PeriodicalId":500086,"journal":{"name":"Research Square (Research Square)","volume":"7 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136229244","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}

The proposed method in [11] is based on state reduction of a monolithic supervisor with respect to each set of controllable events corresponding to each component agent. A supervisor is localizable if state cardinality in each local controller is less than the number of states in the reduced supervisor, constructed by the proposed method in [10]. A supervisor is reducible if state cardinality of the constructed generator by the supervisor reduction procedure is less than the number of states of the original supervisor. In this paper, we define exclusive control consistency (ECC) property for a pair of states and prove that this property is a sufficient condition to guarantee reducing the event cardinality in each local controller comparing to the reduced supervisor. It is shown that reducibility and localizability properties are stronger than having ECC states in the original supervisor. The implementation of local controllers on industrial systems is facilitated by state reduction, whereas communication traffic between each pair of local controllers is reduced by event reduction.","PeriodicalId":500086,"journal":{"name":"Research Square (Research Square)","volume":"10 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136227758","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}
