We explore the structural evolutions of stoichiometric LiMO_(2)using the first-principles calculations combined with the cluster expansion *** automatically obtain the ground state structures of the stoichiometric LiMO_(2)by just considering the cation orderings in the quasi rock-salt structures and the following structural relaxations due to both the atomic size mismatches and the Jahn–Teller *** point out that,on the one hand,the cation orderings are mainly determined by the nearest,the second nearest,and the third nearest cation interactions and can be obtained from the‘phase diagram’we have built using the relative strengths of effective cluster interaction(ECI).On the other hand,the structural relaxations are dominated by the crystal field splitting(CFS)energies,i.e.,structures with larger CFS energies are more *** calculating the ECIs and CFS energies for various structures of LiMO_(2),we clearly show how ECI and CFS play roles in determining the structural evolution mechanism of these systems.

In this paper, the authors introduce a new definition of ∞-tilting(resp. cotilting) subcategories with infinite projective dimensions(resp. injective dimensions) in an extriangulated category. They give a Bazzoni characterization of ∞-tilting(resp. cotilting)subcategories. Also, they obtain a partial Auslander-Reiten correspondence between ∞-tilting(resp. cotilting) subcategories and coresolving(resp. resolving) subcategories with an E-projective generator(resp. E-injective cogenerator) in an extriangulated category.

Timestamps play a key role in process mining because it determines the chronology of which events occurred and subsequently how they are ordered in process *** timestamp in process mining gives an insight on process performance,conformance,and *** therefore means problems with the timestamp will result in misrepresentations of the mined process.A few articles have been published on the quantification of data quality problems but just one of the articles at the time of this paper is based on the quantification of timestamp quality *** article evaluates the quality of timestamps in event log across two axes using eleven quality dimensions and four levels of potential data quality *** eleven data quality dimensions were obtained by doing a thorough literature review of more than fifty process mining articles which focus on quality *** evaluation resulted in twelve data quality quantification metrics and the metrics were applied to the MIMIC-ll dataset as an *** outcome of the timestamp quality quantification using the proposed typology enabled the user to appreciate the quality of the event log and thus makes it possible to evaluate the risk of carrying out specific data cleaning measures to improve the process mining outcome.

Objective: To evaluate the effectiveness and safety of Chinese medicine(CM) in the treatment of coronavirus disease 2019(COVID-19) in China. Methods: A multi-center retrospective cohort study was carried out, with cumulative CM treatment period of 3 days during hospitalization as exposure. Data came from consecutive inpatients from December 19, 2019 to May 16, 2020 in 4 medical centers in Wuhan, China. After data extraction, verification and cleaning, confounding factors were adjusted by inverse probability of treatment weighting(IPTW), and the Cox proportional hazards regression model was used for statistical analysis. Results:A total of 2,272 COVID-19 patients were included. There were 1,684 patients in the CM group and 588 patients in the control group. Compared with the control group, the hazard ratio(HR) for the deterioration rate in the CM group was 0.52 [95% confidence interval(CI): 0.41 to 0.64, P<0.001]. The results were consistent across patients of varying severity at admission, and the robustness of the results were confirmed by 3 sensitivity analyses. In addition, the HR for all-cause mortality in the CM group was 0.29(95% CI: 0.19 to 0.44, P<0.001).Regarding of safety, the proportion of patients with abnormal liver function or renal function in the CM group was smaller. Conclusion: This real-world study indicates that the combination of a full-course CM therapy on the basic conventional treatment, may safely reduce the deterioration rate and all-cause mortality of COVID-19patients. This result can provide the new evidence to support the current treatment of COVID-19. Additional prospective clinical trial is needed to evaluate the efficacy and safety of specific CM interventions.(Registration No. ChiCTR2200062917)
