As the title says, while I am using Gaussian Mixture Model emissions, I sometimes get errors such as: n_samples=31 should be >= n_clusters=32 Here is the full error report: ---...
By considering waves which propagate through sample surfaces as light interacts with them, a new technique could make it easier for researchers to create real-time images of microscopic samples. How did the COVID pandemic end so abruptly? New York | Heidelberg, 21 August 2024 New analysis sugges...
If the populations are identical in location, the ranks of combined observations should be randomly mixed between the two samples. The number of times a score from group 1 precedes a score from group 2 and the number of times a score from group 2 precedes a score from group 1 are ...
ion feature intensity (LC-MS1 peak area) can be aggregated by GROUPS from the metadatable with either a 离子特征强度(LC-MS1峰面积)可以由 GROUPS 从元可测数据中聚集得到Sum 总之 or 或者Average 一般 (RECOMMENDED, because it is more robust to the difference in the number of samples per GROUPS...
Reef framework, which is generally not discernible in natural exposures, was documented from slabbed hand samples and thin sections35. Fig. 1: Geographic and stratigraphic location of the study material. a, Location of Little Dal reefs in northwestern Canada. Scale bar, 100 km. b, Stratigraphic...
Levels in serum samples from 40 healthy subjects obtained after overnight fast and 3 hours after a high-fat meal. Both APOB-48 and IAP were greater in subjects without blood antigen A (blood groups B and O) than in those with this antigen (blood groups A and AB). The non-A group ...
To examine the impacts of the “plus” intervention over and above those of the PSSN alone, 130 villages (clusters) were randomized into two study arms: (1) Cash Plus communities receiving the PSSN combined with adolescent-targeted “plus” components (treatment arm); and (2) PSSN-only ...
("Methods" section), are grown on a 1μμm thick GaN buffer, deposited onto ac-plane sapphire (Al2O3) substrate. The samples are covered with a GaN capping layer with thickness ranging between 40 and 300 nm to prevent the formation ofα-Fe NCs at the sample surface9,27. A schematic...
