Vasomotion is the regular variation in tone of arteries. In our study, we suggest a model for the initiation of vasomotion. We suggest that intermittent release of Ca(2+) from the sarcoplasmic reticulum (SR, cytosolic oscillator), which is initially unsynchronized between the vascular smooth muscle cells, becomes synchronized to initiate vasomotion. The(More)
We have determined whether the nitroxide antioxidant, tempol, can oppose tissue loss and improve recovery of locomotor function following contusion injury of the spinal cord. Contusion injury was produced in rats at the level of T10 with a weight-drop device and locomotor recovery was determined with the 21-point Basso, Beattie and Bresnahan (BBB) scale.(More)
The gene expression data are usually provided with a large number of genes and a relatively small number of samples, which brings a lot of new challenges. Selecting those informative genes becomes the main issue in microarray data analysis. Recursive cluster elimination based on support vector machine (SVM-RCE) has shown the better classification accuracy(More)
This paper proposes a new method for document categorization, based on support vector machine (SVM) using a concept vector model (CVM). The traditional document classification usually ignores the semantic relations among the keywords or documents. To effectively solve the semantic problem, the domain ontology is used to capture the semantic information(More)
Automatic keyphrase extraction from documents is a task with many applications in information retrieval and natural language processing. Previously, Several keyphrase extraction methods have been proposed based on different techniques. In this paper a keyphrase extraction algorithm based on the least squares support vector machine is proposed. In order to(More)
PURPOSE To explore the effects of Icaritin on chronic myeloid leukemia (CML) cells and underlying mechanisms. METHOD CML cells were incubated with various concentration of Icaritin for 48 hours, the cell proliferation was analyzed by MTT and the apoptosis was assessed with Annexin V and Hoechst 33258 staining. Cell hemoglobinization was determined.(More)
In this paper, we compare and contrast SPIN and VIS, two widely used formal verification tools. In particular, we devote special attention to the efficiency of these tools for the verification of communications protocols that can be implemented either in software or hardware. As a basis of our comparison, we formally describe and verify the Asynchronous(More)
