C57BL/6 mice were whole-body irradiated with 75 mGy X-rays with or without SRBC immunization. The splenic lymphocytes were analyzed by flow cytometry with fluorescent monoclonal antibodies 4 and 7 days after irradiation. No significant changes were found in the ratio of helper to suppressor T lymphocytes after irradiation, no matter it was calculated from the percentage or the absolute number of the subsets. However, 4 days after irradiation plus immunization, the ratio was higher than that in the group with irradiation alone and that in the group with immunization alone probably due to the significant increase in number of the helper T cells in the spleen. The present study demonstrated that ionizing radiation per se in a dose within 0. 1 Gy would not significantly change the ratio of regulatory T subsets.

International Journal of Automation and computing 2010年第1期7卷 39-46页

Inspired by human behaviors, a robot object tracking model is proposed on the basis of visual attention mechanism, which is fit for the theory of topological perception. The model integrates the image-driven, bottom-up attention and the object-driven, top-down attention, whereas the previous attention model has mostly focused on either the bottom-up or top-down attention. By the bottom-up component, the whole scene is segmented into the ground region and the salient regions. Guided by top-down strategy which is achieved by a topological graph, the object regions are separated from the salient regions. The salient regions except the object regions are the barrier regions. In order to estimate the model, a mobile robot platform is developed, on which some experiments are implemented. The experimental results indicate that processing an image with a resolution of 752 × 480 pixels takes less than 200 ms and the object regions are unabridged. The analysis obtained by comparing the proposed model with the existing model demonstrates that the proposed model has some advantages in robot object tracking in terms of speed and efficiency.
