WebMar 23, 2024 · For steel members, a slenderness ratio below 50 can be considered “short”. A slenderness ratio greater than 200 tells us the member is “long”, and buckling from compressive forces should be considered. Members with slenderness ratios between those two values are considered “intermediate”, where engineering judgment should be used. WebApr 28, 2024 · Methods: Here we investigate the effect of gene length bias in scRNA-Seq across a variety of datasets that differ in terms of capture technology, library preparation, cell types and species. Results: We find that scRNA-seq datasets that have been sequenced using a full-length transcript protocol exhibit gene length bias akin to bulk RNA-seq data. grainless breakfast cereal
