Database normalization is a central part of database design in which we re-organise the data stored so as to progressively ensure that as few anomalies Occur as possible upon insertions, deletions and/or modifications. Successive normalizations of a database to higher normal forms continue to ...

The implications of this assumption have been discussed for RNA-Seq data in detail (13, 14) and specific subset normalization methods have been proposed (15). These methods, however, are based on either spike-in controls or the a priori definition of sample conditions. The latter is intrinsica...

In the one extreme, a database can be set up to provide the results of a single known query so that the use of available of resources are maximized and response time minimized, but at the cost of all other queries being suboptimally executed. In the other extreme, when no query is ...

Therefore, we benchmark how well the ALDEx2 package, a transformation-based DA tool, detects differential expression in high-throughput RNA-sequencing data (RNA-Seq), compared to conventional RNA-Seq methods such as edgeR and DESeq2. Results: To evaluate the performance of log-ratio ...
In the case of testing, ground truth landmarks were used from the corresponding dataset. Exp 1. Testing Benchmark: LFW. The LFW [8] database contains about 13,000 images for about 1680 sub- jects with a total of 6,000 defined matches. The primary nuisance transformations are illumination...
Unfortunately, there is no available database of normal pediatric hippocampal volumes for comparison. Absolute hip- pocampal volumes corrected using cranial volumes have been reported to yield the greatest reduction in variance of corrected hippocampal volumes (8). Although the weights of the patients ...
