Optimal Design Of English Auctions With Discrete Bid Levels [PDF]

, 2007
This paper considers a form of ascending price English auction widely used in both live and online auctions. This discrete bid auction requires that the bidders submit bids at predetermined discrete bid levels, and thus, there exists a minimal increment ...

Systematic evaluation of the isolated effect of tissue environment on the transcriptome using a single-cell RNA-seq atlas dataset

BMC Genomics
Background Understanding cellular diversity throughout the body is essential for elucidating the complex functions of biological systems. Recently, large-scale single-cell omics datasets, known as omics atlases, have become available.

Dynamic behaviors of a discrete Lotka-Volterra competitive system with the effect of toxic substances and feedback controls

Advances in Difference Equations, 2017
By noting the fact that the intrinsic growth rate are not positive everywhere, we revisit Lotka-Volterra competitive system with the effect of toxic substances and feedback controls.

Yet another approach to compositional synthesis of discrete event systems [PDF]

, 2008
A two-pass algorithm for compositional synthesis of modular supervisors for large-scale systems of composed finite-state automata is proposed. The first pass provides an efficient method to determine whether a supervisory control problem has a solution ...
