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 ...
Molecular phylogeny indicates that metazoans (animals) emerged early in the Neoproterozoic era1, but physical evidence is lacking. The search for animal fossils from the Proterozoic eon is hampered by uncertainty about what physical characteristics to expect. Sponges are the most basic known animal ty...
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 ...
Genetic organisation of the genes involved in metabolism of LNnT. Based on the results of the microarray analyses performed and functional annotation of LNnT/LacNAc-upregulated genes, we propose that the products of the gene clusters Bbr_0526-0530, Bbr_1551-1553 and Bbr_1554-1560 (...
One of the five samples of the WT was identified as an outlier by a Grubb’s test with alpha at 0.05 and thus excluded from the analysis. Because the signal in WGA-stained sections was clustered, we analyzed the percent volume occupied by these clusters: we generated the extended focus ...
Metropolis–Hastings algorithm : used to generate a sequence of samples from the probability distribution of one or more variables Midpoint circle algorithm : an algorithm used to determine the points needed for drawing a circle Minimum bounding box algorithms : find the oriented minimum bounding bo...
("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...
