132 133 During positive and negative selections within the thymus gland, self-reactive T cells are first removed (negative selection) before T cells with functional receptors are selected (positive selection).
To test explanation (3) we looked at the relative powers of the LRTs using simulations with a weakly selected positive selection class (ω distribution of 40% ω = 0, 40% ω = 0.25, 10% ω = 1.0 and 10% ω = 1.5).
Details of the number of backcross progenies planted in each generation for all the 12 RP varieties and the number of plants selected positive for both foreground and recombinant selection markers for each cross are shown in Additional file 6: Table S1.
Additionally random selected positive PCRs were sequenced.
When asked to describe their work, respondents typically selected positive or neutral words.
The selected positive clones were end-sequenced to check the overlap between the fosmid clones and the adjacent BAC clones.
The company 's corporate citizenship report from 2004 failed to mention supplier auditing or child labour policies, but focuses instead on selected, positive "case studies" of the company's impact on society.
Still, even carefully selected positive data can be useful.
Following this, for each word form the lexicon, denoted as w, its frequency among the selected positive and negative messages was calculated.
The advanced backcross progenies of BC2 and BC3 were generated from the crosses of selected positive BC1F1 (16 plants from 40) and BC2F1 (14 plants from 40) by MAS (Figure 1).
