Dynamical fluctuations in critical regime and across the 1st order phase transition
In this proceeding, we study the dynamical evolution of the sigma field
within the framework of Langevin dynamics. We find that, as the system evolves
in the critical regime, the magnitudes and signs of the cumulants of sigma
field, and , can be dramatically different from the equilibrated
ones due to the memory effects near . For the dynamical evolution across
the 1st order phase transition boundary, the supercooling effect leads the
sigma field to be widely distributed in the thermodynamical potential, which
largely enhances the cumulants , correspondingly.Comment: 4 pages, 2 figures, proceedings for Quark Matter 201
Enhancements of high order cumulants across the 1st order phase transition boundary
In this proceeding, we investigate the dynamical evolution of the
field with a trajectory across the 1st order phase transition boundary, using
Langevin dynamics from the linear sigma model. We find the high order cumulants
of the field are largely enhanced during the dynamical evolution,
compared with the equilibrium values, due to the supercooling effect of the
first order phase transition.Comment: 4 pages, 2 figures, SQM proceeding, with minor change
Rehabilitation recognition skeleton data depth learning based on RNN
With the extensive application of deep learning in the field of human rehabilitation, skeleton based rehabilitation recognition is becoming more and more concerned with large-scale bone data sets. The key factor of this task is the two intra frame representations of the combined co-and the inter-frame. In this paper, an inter frame representation method based on RNN is proposed. Pointtion of each joint is joint-coded they are assembled into semantic both spatial and temporal domains.we introduce a global spatial aggregation which is able to learn superior joint co features over local aggregation
Original Article Angiotensin receptor blockers (ARBs) reduce the risk of lung cancer: a systematic review and meta-analysis
Abstract: Angiotensin receptor blockers (ARBs) are the most commonly used blood pressure-lowering drugs in the world. However, the preventive value of ARBs on lung cancer is still controversial. Therefore, it was necessary for us to perform a meta-analysis to evaluate the value of ARBs on lung cancer risk. We searched the PubMed database as well as the Web of Science database. The overall effect was measured by odds ratio (OR) and corresponding 95% confidence intervals (CI). The significance of the pooled ORs was determined by the Z test with a P value less than 0.05 considering statistically significant. In this meta-analysis, we found ARBs could decrease the lung cancer risk (OR=0.81, 95% CI 0.69-0.54). The stability of the results was tested by sensitivity analysis. The result was not a significant change, suggesting that the result of our meta-analysis was stable. In conclusion, our meta-analysis demonstrated that ARBs was significantly associated with lower lung cancer
Quantitative analysis of multi-components by single marker method combined with UPLC-PAD fingerprint analysis based on saikosaponin for discrimination of Bupleuri Radix according to geographical origin
Background: Saikosaponins are regarded as one of the most likely antipyretic constituents of Bupleuri Radix, establishing a comprehensive method that can reflect both the proportion of all constituents and the content of each saikosaponin is critical for its quality evaluation.Methods: In this study, the combination method of quantitative analysis of multiple components with a single marker (QAMS) and fingerprint was firstly established for simultaneous determination of 7 kinds of saikosaponins in Bupleuri Radix by ultra-high performance liquid chromatography (UPLC).Results: The results showed that saikosaponin d was identified as the optimum IR by evaluating the fluctuations and stability of the relative calibration factors (RCFs) under four different conditions. The new QAMS method has been confirmed to accurately quantify the 7 kinds of saikosaponins by comparing the obtained results with those obtained from external standard method and successfully classify the 20 batches of Bupleuri Radix from 8 provinces of China. The experimental time of fingerprint was significantly reduced to approximate 0.5Â h through UPLC-PAD method, a total of 17 common peaks were identified.Conclusion: The QAMS-fingerprint method is feasible and reliable for the quality evaluation of Bupleuri Radix. This method could be considered to be spread in the production enterprises of Bupleuri Radix
Snap: an integrated SNP annotation platform
Snap (Single Nucleotide Polymorphism Annotation Platform) is a server designed to comprehensively analyze single genes and relationships between genes basing on SNPs in the human genome. The aim of the platform is to facilitate the study of SNP finding and analysis within the framework of medical research. Using a user-friendly web interface, genes can be searched by name, description, position, SNP ID or clone name. Several public databases are integrated, including gene information from Ensembl, protein features from Uniprot/SWISS-PROT, Pfam and DAS-CBS. Gene relationships are fetched from BIND, MINT, KEGG and are integrated with ortholog data from TreeFam to extend the current interaction networks. Integrated tools for primer-design and mis-splicing analysis have been developed to facilitate experimental analysis of individual genes with focus on their variation. Snap is available at and at
