We call Π the preconditioning matrix, because, as it will be explained in Section 3.2, it is used to increase the convergence rate of the recursions (8).
However, some exposure misclassification is possible with the job exposure matrix because of uncertainty in expert assessment (Van Tongeren et al. 2002).
In this paper, we assumed normal CPDFs with equal covariance matrices, because in many cases this choice provides a simple and robust method of discrimination, especially when many variables are available and have to be selected [ 17- 19].
The derived transition function is generally a full matrix, because changes in load and generation buses influence multiple SVs.
The inability to mineralize woven bone matrix because of a decrease in BSP would account for the decrease in mineralized nodules identified by von Kossa staining.
In conclusion, although open agricultural land-use types tend to have fewer species in lower numbers, all land-use types contribute to overall biodiversity of the agricultural matrix because of distinct communities in shaded vs. non-shaded land-use types.
Most assays for intracellular analytes use peripheral blood mononuclear cells (PBMCs) as a matrix because of their role in the immune system and because their nucleoside metabolism is fully functional, as opposed to that of red blood cells and platelets.
The existence of missing data is unavoidable, especially in a large data matrix, because of gene loss and difficulty in obtaining the sequences, but information about the amount and distribution of incompleteness should be clearly stated and their potentially misleading effects should be studied and/or carefully discussed.
When the UFPNBR/HNCC nanocompound powder is mixed with crude NBR, UFPNBR particles are easily dispersed well in NBR matrix because of their good compatibility, thus the HNCC particles are also dispersed in NBR matrix because of the carrier aidance of UFPNBR particles in 7 phr HNCC loading range, then the novel NBR/UFPNBR/HNCC ternary nanocomposites is fabricated.
When the temperature decreases from room temperature to liquid nitrogen temperature (77 K), a strong CNT epoxy interfacial bonding is observed due to the thermal contraction of epoxy matrix because of the big differences in thermal expansion coefficients of epoxy and MWCNTs, resulting in a higher reinforcing efficiency.
