    Master of ScienceDepartment of Computer ScienceHande McGintyOptimal routing of goods is crucial when addressing supply chain challenges. Within this context, grain transportation stands out as a significant sub-issue. For this research,grain transportation is defined as the process of determining the best routes between grain elevators and railway stations. As in most supply chain and path finding problems, this process is also challenging due to the complexity and dynamics of the domain. In this work, we propose a novel application that uses the KNowledge Acquisition and Representation Methodology (KNARM) and the KnowWhereGraph to enhance the path-finding process during transportation of goods, in this specific case grain. KNARM is a methodology that allows for creating and maintaining modular ontologies that can represent complex domains and support reasoning. KnowWhereGraph, is a densely connected, cross-domain knowledge graph and geo-enrichment service stack that provides rich and up-to-date geospatial information. By integrating these two components, our application aims to leverage the semantic and spatial knowledge to find more accurate and efficient paths for grain transportation. To find the optimal path, we use the A* algorithm, which is a heuristic search algorithm that can find the optimal path between two locations, taking into account the criteria of cost, time, and risk. The A* algorithm can also adapt to dynamic and uncertain situations, such as changes in weather, traffic, or security conditions by updating the paths. We also discuss the challenges and limitations that we faced during the ontology development and data integration process, and how we resolved or mitigated them. Our work demonstrates the potential of using ontologies and knowledge graphs to enhance path-finding problems in complex and dynamic domains. We show that our application can find accurate, efficient, and robust paths for grain transportation, based on the feedback from domain experts and GIS experts. We also provide new insights into the modeling of the factors that may affect grain transportation in Ukraine, such as weather, traffic, and security conditions

    Metabolic characterization of different-aged Monascus vinegars via HS-SPME-GC-MS and CIL LC-MS approach

    Yongchun Monascus vinegar is one of famous Chinese vinegar types because of its unique flavor and special bioactivity. Aging process has been regarded as crucial for enhancing the flavor and quality of vinegar. However, changes in the metabolites along the aging of the vinegar are still poorly understood. In this study, a combination of headspace solid-phase micro-extraction gas chromatography-mass spectrometry and chemical isotope labeling liquid chromatography-mass spectrometry methods was used for investigating the metabolomes of one-year-old, five-year-old and thirty-year-old YMVs. DPPH radical-scavenging activity, total phenolics content, and total flavonoids content correlated positively with the aging time. The metabolite compositions in the different-aged vinegars were clearly separated in the PCA analysis. A total of 1133 volatile and non-volatile metabolites changed along the aging; 392 metabolites were in common whereas 126, 84, and 54 changed metabolites were unique to one-to-five year, one-to-thirty year, and five-to-thirty year-old vinegar comparisons, respectively. Organic acids and dipeptides, exhibiting taste characteristics, with constant increase or decrease with aging time and correlated with antioxidant capacities could be used as biomarkers for differentiating the different-aged vinegars. The results revealed aging time related changes in volatile and non-volatile metabolites in YMVs, providing useful knowledge for improving their quality.Peer reviewe

    Agents of May Fourth. Jing Yinyu, Xu Zhongnian, and the Early Introduction of Modern Chinese Literature in France

    Get PDF
    Jing Yinyu (1901-1931?) and Xu Zhongnian (1904-1981) played a pivotal role in the dissemination of modern Chinese literature in France at the turn of the 1930s. Best known as Lu Xun’s first translator into a Western language and a friend of Romain Rolland’s, Jing compiled the Anthologie des conteurs chinois modernes in 1929. In his Anthologie de la littĂ©rature chinoise. Des origines Ă  nos jours, published in 1932, Xu also devoted a section to recent literary developments. By analyzing the nature of the two projects, the translated corpora, and their paratexts, I will describe the features of Jing’s and Xu’s dissemination of May Fourth literature in France and scrutinize their artistic and ideological stance vis-Ă -vis the new literary scene. Ultimately, I will attempt to pinpoint in what terms the two scholars-cum-translators’ agency contributed to foreign readers’ awareness of the cultural, social and political experience of the May Fourth Movement

    Large-scale mapping of human protein–protein interactions by mass spectrometry

    Mapping protein–protein interactions is an invaluable tool for understanding protein function. Here, we report the first large-scale study of protein–protein interactions in human cells using a mass spectrometry-based approach. The study maps protein interactions for 338 bait proteins that were selected based on known or suspected disease and functional associations. Large-scale immunoprecipitation of Flag-tagged versions of these proteins followed by LC-ESI-MS/MS analysis resulted in the identification of 24 540 potential protein interactions. False positives and redundant hits were filtered out using empirical criteria and a calculated interaction confidence score, producing a data set of 6463 interactions between 2235 distinct proteins. This data set was further cross-validated using previously published and predicted human protein interactions. In-depth mining of the data set shows that it represents a valuable source of novel protein–protein interactions with relevance to human diseases. In addition, via our preliminary analysis, we report many novel protein interactions and pathway associations
