Revisiting demand rules for gene regulation.
Starting with Savageau's pioneering work regarding demand rules for gene regulation from the 1970s, here, we choose the simplest transcription network and ask: how does the cell choose a particular regulatory topology from all available possibilities? According to the demand rules, a cell chooses an activator based regulation of a target if the target protein is required for most of the time. O...
متن کاملRevisiting Generic Bases of Association Rules
As a side effect of unprecedented amount of digitization of data, classical retrieval tools found themselves unable to go further beyond the tip of the Iceberg. Data Mining in conjunction with the Formal Concept Analysis, is a clear promise to furnish adequate tools to do so and specially to be able to derive concise generic and easy understandable bases of ”hidden” knowledge, that can be relia...
متن کاملRevisiting Acyclicity and Guardedness Criteria for Decidability of Existential Rules
Existential rules, i.e. Datalog extended with existential quantifiers in rule heads, are currently studied under a variety of names such as Datalog+/–, ∀∃rules, and tuple-generating dependencies. The renewed interest in this formalism is fuelled by a wealth of recently discovered language fragments for which query answering is decidable. This paper extends and consolidates two of the main appro...
متن کاملRevisiting stopping rules for iterative methods used in emission tomography
The expectation maximization algorithm is commonly used to reconstruct images obtained from positron emission tomography sinograms. For images with acceptable signal to noise ratios, iterations are terminated prior to convergence. A new quantitative and reproducible stopping rule is designed and validated on simulations using a Monte-Carlo generated transition matrix with a Poisson noise distri...
متن کاملDemand for and Regulation of Cardiac Services
Efforts to regionalize cardiac services can increase access costs for patients. This study quantifies this trade off by estimating the effects of changes in the regulation of hospital services on treatments and outcomes. A demand model for surgery services is specified in which heart attack victims form expectations of the need for and productivity of surgery in their choice of hospital and tre...
