Existence of Optimal Energy Saving Parameters for Different Industrial Processes
energy saving optimal operational mode incubation time brittle fracture rocks
2012/9/24
It is demonstrated that energy input for fracture in many industrial processes can be optimised so that the energy cost of the process is minimised. Using a simple example of central crack it is show...
Existence of Periodic Solution for a Predator-prey System with Feedback Control
Hassell-Varely type predator-prey coincidence degree theorem Lyapunov function global stability
2012/9/24
A Hassell-Varely type predator-prey system with feedback controls is studied. Using the comparison, continuation theorems and coincidence degree theorem, the existence of positive periodic solutions f...
Existence and Uniqueness of the Positive Solution to a Predator-prey Model with Stochastic Perturbation
Itos formula Brownian motion existence and uniqueness
2012/9/24
In this paper, a predator-prey model is estab lished with the modified Holling-type II schemes with stochastic perturbation. We mainly use Lyapun ov function and comparison theorem to show that there ...
Classification of Saccharomyces cerevisiae promoter regions into distinct chromatin classes reveals the existence of nucleosome-depleted hotspots of transcription factor occupancy
Classification Saccharomyces cerevisiae promoter regions distinct chromatin classes existence nucleosome-depleted hotspots factor occupancy
2010/11/15
Transcription factors (TF) play an essential role in the cell as locus- and condition-specific recruiters of transcriptional machinery or chromatin-modifying complexes. However, predicting the in vivo...
