Species in the tail of rank-abundance curves. Investigates the abundance and distribution of species in the tail of rank-abundance curves in other location within their respective geographical ranges. ... Murray,R Brad,Rice,... - 《Ecology》 被引量: 104发表: 1999年 Properties of species in ...
[6, 7], which overwhelmingly contribute to biogenic gas in coals with elevatedvitrinite reflectance(Ro~0.6%–0.8%)[7, 25], the chemical gas composition and the ratio of the abundance of CH4relative to higher hydrocarbons (i.e., “gas dryness”) became indispensible proxies for evaluating the...
Data truncation as in a p-log transform can be avoided via a generalized log (g-log) transformation (Eqn. 5). S rj ≈ I rj = a j A rj η rj + φ rj where a: probe affinity; A: abundance; η: multiplicative noise; φ: additive noise Eqn. 3...
For cells delivering pro-tumor suppression, compared with TFP tumors, the abundance of macrophage was greater in TFN tumors (Fig. 5A). Furthermore, using xCell, we found the relative fraction of M1 macrophage in TFP tumors was significantly lower than TFN tumors (one-sided Wilcoxon rank-...
The choice of the smoother span supplied to the lowess function (see Methods section) can also effect the calibration curves. We have evaluated a range of values for this parameter (data not shown) and have chosen 0.25 as the default for GRSN. However, in a few cases, this default value...
