An associative memory based on the immune networks: perspectives on internal image with antibody dynamics

Immune memory can be regarded as an equilibrium state of immune network system with nonlinear dynamical behavior. The rapid response of immune systems to the second-time antigen is owing to the stable structure of memory state forming by a closed idiotypic immune network. Internal image of an antigen is defined while memory state is formed via such network. A dynamical system of cell population based on antibody chains and tree structure is proposed which explains how the memory state is formed in the immune network. We also propose a network dynamics model of idiotypic immune network based on cross-reactive correlation matrix to fill the gap of weaker assumption for artificial immune memory. Mathematical theory of associative memory is also explored, particularly, combining network structure and dynamical systems are some breakthrough in this paper. We realize that cyclic idiotypic immune network and dynamical systems can be a cooperative description for immune memory.

NOVEL APPROACH FOR t–J MODEL WITH ELECTRON SCATTERINGS

This report proposes a graphical-like approach for simulating the Hamiltonian of the t–J model. The two spin states are modeled by the two emitting layer, the kinematics of the electrons and the causalities between the operators are satisfied through the event cone. Operators and the event cone are integrated together, and the results indicate that this approach can provide information during the evolution of the t–J model. In addition, parameters that can be accessed by this approach are consistent with general requirements on values of t and J in the t–J model. Furthermore, our approach also includes the solution with vanishing hopping amplitude (tij = 0) and the H∞ solution.

Effects of Poly-L-Ornithine and Fibronectin Coatings for Human Melanocyte Cell Illuminating Experiments

The uses of light spots to stimulate cell activity, such as optogenetic or optical neural guiding, have recently received considerable attention. The dynamic behavior of the cells depends on appropriate attachment conditions for the induction of appropriate biochemical and physiological responses. This article reports the possible effects of two different substrate coatings (poly-L-Ornithine and Fibronectin) on cell activity in cell illuminating experiments. The results using Human Melanocyte Cells (HMCs) indicate that these two coatings influence cell activity in different ways.

Immune Response and Memory: Perspectives on Stability of Cyclic Idiotypic Network

Immune memory can be regarded as an equilibrium state of immune network system with nonlinear behavior. The rapid response of immune systems to the second-time antigen is owing to the stable structure of memory state forming by a closed loop of the idiotypic immune network. A dynamical system is proposed which explains how the memory state is formed and stabilized in the immune network.

HMC and fibroblast illuminating experiments using microdisplay

Techniques like optical neural guiding, photodynamic therapy and photosynthesis of the cell all required specific spatial energy distribution. Influences factors like the wavelength, polarization, spatial intensity distribution are all required, and the appropriate illumination condition for the cells inside the incubator are required to meet more complicated conditions. We report the system that using of the spatial light modulator to provide a multi-points control for the cell culturing. This system is modified from the commercialized projection system to reduce the cost. It is now possible to apply it to other bio-culturing related applications. Results for Human Melanocyte HMC, Glia cell and fibroblast cell are discussed.
