整群抽样cluster sampling多阶段抽样 multi-stage sampling
A clustered sampling method was used to select the monitoring sites. During data collection, a random sampling procedure was used to identify schoolchildren for the collection of urine samples. Urine samples were transported to the laboratory, and a 10 mL syringe was then used to extract 10 mL...

For UMI-based methods the scmapCell followed by scmapCell2Cluster method was used with w = 2. Multiple datasets were used to draw conclusions with scmap, and transcriptionally similar clusters (such as trophoblast or amnion) may map incorrectly if both are not present due to the limited ...

This is a flaw with the method. Michael Spaeth posted on Friday, February 05, 2010 - 7:20 am I have the same problems with MLR-testing as described above (negative chi-square). In this situation, is it o.k. to use the Wald-test in combination with MLR and COMPLEX/CLUSTER in ...
The annotations of cell identity on each cluster were defined by the expression of known marker genes. We compared the results for cell lineage annotations based on independent cell clusters from different clustering methods as follows: Seurat, CIDR61, RCA62, and SC3 (ref. 63) (Supplementary ...
Landslide susceptibility zonation method based on C5.0 decision tree and K-means cluster algorithms to improve the efficiency of risk management[J]. Geoscience Frontiers, 2021, 12(6): 101249. DOI: 10.1016/j.gsf.2021.101249 Citation: Zizheng Guo, Yu Shi, Faming Huang, Xuanmei Fan, Jinsong ...
We derive sparse variational inference with decoupled functional sampling to represent vector field posteriors. We also introduce a probabilistic shooting augmentation to enable efficient inference from arbitrarily long trajectories. The method demonstrates the benefit of computing vector field posteriors, with...
We used the aforementioned LC-IM-MS/MS method to acquire the RTs, CCS values, and MS/MS spectra of 97 derivatized sterol standards. RTs and CCS values of sterol standards were acquired by the “Alternating frames” mode. MS/MS spectra of sterol standards were acquired by targeted MS/MS ac...
