In essence, it employs computer algorithms to identify the \"best\" match between two molecules, akin to solving intricate three-dimensional jigsaw puzzles. At a more stringent level, the molecular docking challenge entails predicting the accurate bound association state based on the atomic coordinates of two molecules. This process assumes particular significance in unraveling the mechanistic intricacies of physicochemical interactions at the atomic scale. Notably, the application of docking, especially in the context of protein-small molecule interactions, holds wide-ranging implications for structure-based drug design, given the prevalent use of small compounds as drug candidates. This study provides an overview of docking methodologies, delves into recent key developments, elucidates the physicochemical underpinnings of molecular recognition in protein-ligand interactions, and concludes by addressing the applications of docking in virtual screening, alongside current challenges within existing docking methods.","PeriodicalId":45018,"journal":{"name":"Communications in Information and Systems","volume":"24 3","pages":"199-230"},"PeriodicalIF":0.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11583305/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142711419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prior investigations leveraged smFRET to study the conformational dynamics of single truncated Ubc4 pre-mRNA molecules during splicing, yet these efforts did not prioritize structural modeling. In this study, we develop an smFRET-assisted RNA prediction method to predict the 2D and 3D structures of this pre-mRNA. To achieve this, we initiate the process by generating RNA structural ensembles through coarse-grained molecular dynamics (MD) simulations. Subsequently, inter-dye distances are calculated for these RNA structural ensembles by performing all-atom MD simulations of the dye groups. The ultimate determination of the 2D and 3D structures for the pre-mRNA is achieved by comparing the calculated inter-dye distances with experimental counterparts. Notably, our computational results demonstrate a significant alignment with experimental findings, which involve a conformational change at the 2D level.","PeriodicalId":45018,"journal":{"name":"Communications in Information and Systems","volume":"24 3","pages":"163-179"},"PeriodicalIF":0.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11545564/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142636149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our approach is designed for scenarios where agents are used to collect data using an RGB-D camera and then transmit the information over the regular network to a high-performance server, where a global, dense, and volumetric model of a real-world scene is reconstructed. Our approach uses a content-aware communication planning framework in which agents can prune the gathered RGB-D information according to the transmission policy generated by the server. To generate the transmission policy, we introduce a confidence value to estimate how much each RGB-D pixel contributes to the reconstruction quality, and present an algorithm to find the confidence value. As a result, agents can transmit less RGB-D information without blindly compromising the reconstruction quality as the key-frame method and down-sampling method do. We implement our TSDFFilter framework to achieve real-time agent-assisted 3D reconstruction. Extensive evaluations show that comparing with the key-frame and down-sampling methods, our TSDFFil-ter framework can reduce the bandwidth requirement by up to 36% with similar reconstruction Chamfer distance, and reduce the reconstruction Chamfer distance by up to 78% with similar bandwidth requirement.","PeriodicalId":45018,"journal":{"name":"Communications in Information and Systems","volume":"1 1","pages":"213-239"},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70404404","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}
