In the principal investigation phase, these were then used as a basis for assessing the previously defined pools of characteristics with regard to their individual degree of relevance.
This large amount of variability explained by the second level variable could be attributable to some unknown, or not-directly measurable characteristics (such as surgeon's ability), or to a "pool of unfavourable characteristics", whose effects are negligible if considered individually.
ATLANTA — The task force assigned the difficult task of deciding how much to compensate the victims of a North Carolina sterilization program, which was intended to reduce welfare costs and cleanse the gene pool of undesirable characteristics, settled on a number on Tuesday.
Moreover, research has still not been able to clearly identify a pool of teacher characteristics and classroom practices that consistently improve student learning across countries (Goe 2007).
Four statistical methods were specifically searched for as part of the appraisal: pooling of performance characteristics using a fixed effects [ 14] or random effects [ 15] model; SROC method as described by Moses and colleagues [ 16, 17]; bivariate random effects model (BRM) [ 18, 19]; the HSROC curve as proposed by Rutter and Gatsonis [ 20].
Similarly to what has been done to rationalize the determinants of protein aggregation (Chiti et al., 2003), the cleverSuite identifies the most relevant properties for a specific problem with the main differences being that: (i) fitting parameters are avoided and (ii) features are selected from a large pool of physico-chemical characteristics.
At such characteristic sites, a residue that is highly conserved within the human group but rarely observed in the pool of avian strains (a characteristic variant) is likely to be associated with an important adaptive mutation, whose loss would affect the ability of viruses to propagate amongst human hosts.
Typing of suspected samples was performed by PCR [ 19] on a pool of four isolates having characteristic colony morphology on Columbia agar (shiny, grey, double-haemolytic colonies).
Many of the centrosome irradiated cells, especially those with actin bundles, lost the actin pool characteristic of the lamellae at the cell's leading edge.
The alphaherpesvirus pyrimidine deoxynucleoside kinase, popularly known as thymidine kinase (TK) phosphorylates a wide range of nucleoside substrates, as well as TMP (TK + TMPK activity), and is responsible for the rise in the TTP pool characteristic of HSV-infected cells [ 45].
