Having explored the problems of RT-PCR normalization, the consistency of miRNA expression experiments between RT-PCR and microarray technologies was of further interest to us.
Very few works have explored the problem of test case selection given the constraint that source code analysis is not available.
Ceren Budak and two of her colleagues at University of California, Santa Barbara have explored the problem of how to contain the spread of misinformation in social networks.
Other researchers have explored the problem concerned with the classification of the dataset using rule-based machine-learning methods.
Previously, we have explored the problem of aligning two sequences simultaneously to a profile HMM, but we were not able to design a simple generative model for this purpose [ 16].
The network itself can be thought of as a simple qualitative model in its own right, and many investigators have explored the problem of network inference from gene expression data (for a review see Hecker et al. 2009 and references therein).
To get around these problems, the electronics industry has explored the possibilities of extreme ultraviolet light, X-rays and even the arcane quantum states of light called entangled photon pairs in the hope of making finer patterns on the wafers.
A small number of studies [ 32, 26, 33] have explored the data imbalance problem in the semi-supervised context and proposed effective solutions, but the imbalance degrees were moderate.
Few longitudinal studies of children in the general population have explored the stability of sleep problems, and with mixed findings.
Some previous work on natural gas markets have explored the idea of the "contracts problem" between producers and pipelines, as well as buyers and sellers, to determine pricing of "take-or-pay" contracts [12], or have explored regulatory gaps and prices with perfect and imperfect competition in the gas markets [13].
