(二)容重(假比重)bulk density(ρb)(BD)概念:田间自然垒结状态下单位容积土体(包括土粒和孔隙)的质量或重量(克/厘米3或吨/米3)。曾称土壤假比重(appare specific gravity)。质量以105-110℃下烘干土计,也有人叫干容重。 湿容重(wet bulk density).t=Mt/Vt=Ms+Mw/(Vs+Vw+Va)也有文献叫土壤总容重(...

PURPOSE: To easily adjust the bulk density of ground foamed resin product to desired value by a method wherein the predetermined amount of the ground foamed resin product is agitated under the predetermined heating condition and, during the agitation, the ground foamed resin product is partially he...
Searchlight2 exactly which differential comparisons to include in the MDE. It does so by listing the specific numerator=,denominator= combination of each DE to be included. This DE must also be included in a valid --de parameter. For the sample dataset the broken down command might look like...
Mapping cell type-specific gene expression quantitative trait loci (ct-eQTLs) is a powerful way to investigate the genetic basis of complex traits. A popular method for ct-eQTL mapping is to assess the interaction between the genotype of a genetic locus and the abundance of a specific cell typ...
2b). Thus, patient-specific transcriptomic clusters formed by tumor epithelial cells likely represent biological differences between patients, rather than batch effects.

It is important to ensure that the AF provides new information and does not simply recapitulate the geometry imposed by the embedding coordinates. This may occur, for example, when some cells are expressing a cell-specific marker that is not expressed at all in other cells. In this case, a...
