CD4 T Helper Cells Instruct Lymphopenia-Induced Memory-Like CD8 T Cells for Control of Acute LCMV Infection.

Lymphopenic conditions lead to expansion of memory-like T cells (T), which develop from naïve T cells by spontaneous proliferation. T cells are often increased in the elderly population, AIDS patients, and patients recovering from radio- or chemotherapy. At present, it is unclear whether T cells can efficiently respond to foreign antigen and participate in antiviral immunity. To address this quest...

A "Tuned" Mask Learnt Approach Based on Gravitational Search Algorithm.

Texture image classification is an important topic in many applications in machine vision and image analysis. Texture feature extracted from the original texture image by using "Tuned" mask is one of the simplest and most effective methods. However, hill climbing based training methods could not acquire the satisfying mask at a time; on the other hand, some commonly used evolutionary algorithms li...
