Background: Boolean network (BN) modeling is a commonly used method for constructing gene regulatory networks from time series microarray data. However, its major drawback is that its computation time is very high or often impractical to construct large-scale gene networks. We propose a variable selection method that are not only reduces BN computation times significantly but also obtains optim...

background adulterated herbal weight loss products with containing undeclared synthetic drugs are common and responsible for many serious health damages. objectives the purpose of the study was to determine five synthetic adulterants in eight common herbal weight loss supplements, which are currently sold in iran markets, to verify their presence in supplements, without mentioning on the labels...

Ferrocene is a popular template in material science due to its exceptional characteristics that offer the ability to optimize the selectivity and activity of catalysts by the addition of carefully selected substituents. In combinatorial catalyst development, the high susceptibility to electrophilic substitution reactions offers the opportunity for the rapid introduction of molecular diversity. ...
