An application of bioimage simulation: cooperative binding measurement
نویسندگان
چکیده
For the past century, biologists have attempted to identify and document qualitative properties that underlie molecular binding processes in living cells. Cooperativity in the binding processes represents a primary and highly general mechanism for achieving the collective behaviour that emerges in systemslevel properties of macromolecules, pathways, cells and organisms. Recent progress in robotics and automated techniques for sampling and analyzing complex biological data can reduce statistical uncertainties (or errors) in measuring cooperativity. An identification of the systematic uncertainties that arise from inaccuracy in the measurement processes, however, has been often non-empirical. Here, we propose a comprehensive method to quantitatively evaluate the systematic variances computed not only from a computer simulation of live-cell imaging systems, but also image processing and pattern recognition algorithms for biological images. We then demonstrate that such non-statistical variances can affect our biological interpretation of cooperativity in a binding system of interest. Within this computational scheme, the biological interpretation can be more objectively evaluated and understood under a specific configuration of the measurement processes.

An Adaptive-Robust Control Approach for Trajectory Tracking of two 5 DOF Cooperating Robot Manipulators Moving a Rigid Payload
In this paper, a dual system consisting of two 5 DOF (RRRRR) robot manipulators is considered as a cooperative robotic system used to manipulate a rigid payload on a desired trajectory between two desired initial and end positions/orientations. The forward and inverse kinematic problems are first solved for the dual arm system. Then, dynamics of the system and the relations between forces/momen...

متن کاملIdentification of RNA-binding sites in artemin based on docking energy landscapes and molecular dynamics simulation
There are questions concerning the functions of artemin, an abundant stress protein found in Artemiaduring embryo development. It has been reported that artemin binds RNA at high temperatures in vitro, suggesting an RNA protective role. In this study, we investigated the possibility of the presence of RNA-bindingsites and their structural properties in artemin, using docking energy ...
متن کاملCooperative Control of Multiple Quadrotors for Transporting a Common Payload
This paper investigates the problem of controlling a team of Quadrotors that cooperatively transport a common payload. The main contribution of this study is to propose a cooperative control algorithm based on a decentralized algorithm. This strategy is comprised of two main steps: the first one is calculating the basic control vectors for each Quadrotor using Moore–Penrose theory aiming at coo...
