Definition Of

Cell proliferation is essential for the development and maintenance of all organisms and is dysregulated in cancer. Using synchronized cells progressing through the cell cycle, pioneering microarray studies defined cell cycle genes based on cyclic variation in their expression. However, the concordance of the small number of synchronized cell studies has been limited, leading to discrepancies in definition of the transcriptionally regulated set of cell cycle genes within and between species. Here we present an informatics approach based on Boolean logic to identify cell cycle genes. This approach used the vast array of publicly available gene expression data sets to query similarity to CCNB1, which encodes the cyclin subunit of the Cdk1-cyclin B complex that triggers the G2-to-M transition. In addition to highlighting conservation of cell cycle genes across large evolutionary distances, this approach identified contexts where well-studied genes known to act during the cell cycle are expressed and potentially acting in nondivision contexts. An accessible web platform enables a detailed exploration of the cell cycle gene lists generated using the Boolean logic approach. The methods employed are straightforward to extend to processes other than the cell cycle.

This chapter introduces several modules that can be used to supplement an introductory logic course. The modules cover advanced topics such as rule heuristics, association rules, polythetic vs. monothetic grouping, and subsective adjectives. These topics are all approached using ordinary propositional logic, Boolean algebra with 0-1 variables. The topics are presented using a computational approach. The computations and concepts are elementary and accessible to an undergraduate without further prerequisites. The modules besides introducing advanced topics also facilitate discussion of other logic topics such as the law of the excluded middle, the concept of vagueness, and privative adjectives. This chapter presents new solutions to these problems. The chapter reviews the place of these modules within the context of introductory logic courses and the history of science. The supplementation of an introductory logic course with these modules is expected to strongly motivate students to pursue advanced topics and to increase interest in topics related to logic.

Blind forensic-investigation in a digital image is a new research direction in image security. It aims to discover the altered image content without any embedded security scheme. Block and key point based methods are the two dispensation options in blind image forensic investigation. Both the techniques exhibit the best performance to reveal the tampered image. The success of these methods is limited due to computational complexity and detection accuracy against various image distortions and geometric transformation operations. This article introduces different blind image tampering methods and introduces a robust image forensic investigation method to determine the copy-move tampered image by means of fuzzy logic approach. Empirical outcomes facilitate that the projected scheme effectively classifies copy-move type of forensic images as well as blurred tampered image. Overall detection accuracy of this method is high over the existing methods.
