Introduction: Aiming at starting the ball rolling and contributing humble effort to promote Chinese traditional medicine(CTM), we performed the present study to assess the therapy response of Chinese herbal decoction of Removing Blood Stasis compared to conventional therapy on critical ill patients of advanced cerebral tumor of glioma in ICU. Methods: A total of 6 patients(1 females and 5 males) of glioma were included in this retrospective observational clinical trial. We administered Chinese medicine(Decoction of Removing Blood Stasis, mixed with a variety of effective herbal components) to help them to recover from poor condition. In the meantime, conventional treatment of surgical resection and radio-chemotherapy was applied in cases compared. Results: In 3 cases of CTM, after taking the Chinese herbal decoction for months, most residual intracranial tumor mass reduced according to MRI/CT imaging, and the patient felt free from the complaint of discomfort. The quality of life has been greatly improved, we managed to have prolonged the PFS(Progression-Free-Survival) and TTP(Time-to-Progression) from the onset to date. While in 3 cases compared, conventional treatment of surgical resection and radio-chemotherapy were not able to decrease the metastatic lesions, and the patient’s condition worsen more. We failed in having prolonged the PFS and TTP in the compared cases of conventional treatment. Conclusion: Chinese medicine considers human body as a dynamic platform in which all organs are correlative and bind each other. Our report suggested that Decoction of Removing Blood Stasis might be an additional choice with better benefits and tolerability in the treatment of glioma.

Sparse Reconstructive Evidential Clustering for Multi-View Data

引用

IEEE/CAA Journal of Automatica Sinica 2024年第2期11卷 459-473页

作者： Chaoyu gong yang you School of Computing National University of SingaporeSingapore

Although many multi-view clustering(MVC) algorithms with acceptable performances have been presented, to the best of our knowledge, nearly all of them need to be fed with the correct number of clusters. In addition, these existing algorithms create only the hard and fuzzy partitions for multi-view objects,which are often located in highly-overlapping areas of multi-view feature space. The adoption of hard and fuzzy partition ignores the ambiguity and uncertainty in the assignment of objects, likely leading to performance degradation. To address these issues, we propose a novel sparse reconstructive multi-view evidential clustering algorithm(SRMVEC). Based on a sparse reconstructive procedure, SRMVEC learns a shared affinity matrix across views, and maps multi-view objects to a 2-dimensional humanreadable chart by calculating 2 newly defined mathematical metrics for each object. From this chart, users can detect the number of clusters and select several objects existing in the dataset as cluster centers. Then, SRMVEC derives a credal partition under the framework of evidence theory, improving the fault tolerance of clustering. Ablation studies show the benefits of adopting the sparse reconstructive procedure and evidence theory. Besides,SRMVEC delivers effectiveness on benchmark datasets by outperforming some state-of-the-art methods.

Tropical cyclone genesis over the western north Pacific in la Ni?a decay summers: Comparison between 2018 and 2021

引用

Science China Earth Sciences 2024年第10期67卷 3098-3109页

作者： yunyun lIU Zhensong gong China Meteorological Administration Key laboratory for Climate Prediction Studies National Climate CentreBeijing 100081China Collaborative Innovation Center on Forecast and Evaluation of Meteorological Disasters Nanjing University of Information Science&TechnologyNanjing 210044China

As the primary interannual signal of variability in the tropical ocean-atmosphere interaction, the El Ni?o-Southern Oscillation has a considerable impact on tropical cyclone(TC) activity over the western North Pacific(WNP). Both 2018 and2021 were la Ni?a decay years, but TC activity over the WNP during the two summers(June–August) showed notable differences. In 2018, summer TC activity was unusually high with a total of 18 TCs, and the region of TC genesis was mainly in the central and eastern WNP. In contrast, only 9 TCs were generated in summer 2021, and the region of TC genesis was primarily in the western WNP. By comparing the characteristics of the large-scale environmental conditions over the regions of TC genesis, the thermal factors of the tropical oceans, and the activity of the Madden-Julian Oscillation(MJO), this study revealed the possible causes for the marked differences in TC genesis over the WNP during the two summers, which both had a similar background of la Ni?a decay. The Indian Ocean Basin Mode(IOBM) transitioned of a cold anomaly in the winter of 2017/2018and persisted until summer 2018. At the same time, the Pacific Meridional Mode(PMM) maintained a positive phase, leading to eastward and northward displacement of the Western Pacific Subtropical High in summer, and eastward extension of the tropical monsoon trough, which presented conditions conducive to TC genesis over the Northwest Pacific. Moreover, the days when the MJO stagnated in phases 5 and 6 in the summer of 2018 increased by approximately 150% relative to climatological state,providing dynamic conditions favorable for TC formation. In 2021, the IOBM quickly turned to a warm anomaly in March and persisted until summer, whereas the PMM became a negative phase in January and remained so until summer. At the same time,the MJO stagnated in phases 2 and 3 for up to 47 days, with the center of convection located over the western Maritime Continent, producing conditions unconducive to TC ge
