1. A symbol appearing next to a stock listed on NASDAQ indicating that the share being traded has a miscellaneous right, warrant, or receipt attached to it.

Despite the limited power of linkage analysis to detect QTLs with only 416 DZ twin pairs, we found a region of suggestive linkage on chromosome 3 with an LOD score of 2.
4 Mb, less than 2 Mb from HFE), none of the candidate genes are situated in genomic regions with LOD scores above 1.
To provide significant evidence for such genes, the LOD scores should have exceeded the more conservative experiment-wise threshold level (Lander & Kruglyak 1995).
Listed are the markers and their associated LOD scores, 5% and 1% group-wise threshold LOD scores, and sample sizes, means, and standard errors for V.
Out of 101 polymorphic microsatellites developed, 67 and 48 were grouped in 14 linkage groups using CRIMAP with a LOD score of 3.
The correction constants for computing empirical LOD scores were 0.
LOD] is the number of trios in which the true sire was identified by assigning paternity to the putative sire with the highest LOD score among non-excluded putative sires.
Presence of renal failure (as measured by serum creatinine), serum albumin, LOD score, APACHE II score and use of heparin, frusemide and beta-lactam antibiotics were not independent risk factors for development of thrombocytopenia after adjusting for age and gender.
