With the help of fuzzy approximation method, the minimax matching control problem of immune systems could be easily solved by the proposed fuzzy dynamic game method
via the linear matrix inequality (LMI) selleck chemicals llc technique with the help of Robust Control Toolbox in Matlab. Finally, in silica examples are given to illustrate the design procedure and to confirm the efficiency and efficacy of the proposed method. (C) 2008 Elsevier Ltd. All rights reserved.”
“Viral-vector-mediated gene delivery into Purkinje cells is a promising method for exploring the pathophysiology of the cerebellum; however, it is generally difficult to achieve sufficiently high levels of gene expression in Purkinje cells using viral vectors with a cell-type-specific promoter because of the weakness of transcriptional activity. In this study, we prepared lentiviral vectors that express GFP under the control of various
ubiquitous promoters derived from murine stem cell GSK461364 virus (MSCV), cytomegalovirus (CMV), CMV early enhancer/chicken beta actin (CAG), and Rous sarcoma virus (RSV) and compared their potential to transduce Purkinje cells. Mice were sacrificed 7 days after lentiviral injection and the ratios of GFP(+) Purkinje cells to all transduced cells were determined. The highest transduction ratio was observed when we used lentivectors containing the MSCV promoter: similar to 70% of GFP(+) cells were Purkinje cells, the next highest ratio was for the CMV promoter (similar to 40%), then the CAG promoter (similar to 35%), and the lowest ratio was for the RSV promoter (similar to 10%). Moreover, the highest levels of GFP expression were also caused by the MSCV promoter. Thus, among the ubiquitous promoters examined, the MSCV promoter was the best for the expression of a foreign gene in Purkinje cells in vivo. (C) 2008 Elsevier Ireland Ltd. All rights reserved.”
“A new technique for the modeling
of perennial vegetation patchiness in the arid/semiarid climatic zone is suggested. Incorporating the stochasticity that affects life history of seedlings and the deterministic dynamics of Selleckchem BLZ945 soil moisture and biomass, this model is flexible enough to yield qualitatively different forms of spatial organization. In the facilitation-dominated regime, scale free distribution of patch sizes is observed, in correspondence with recent field studies. In the competition controlled case, on the other hand, power-law statistics is valid up to a cutoff, and an intrinsic length scale appears. (C) 2008 Elsevier Ltd. All rights reserved.”
“We investigate the relationship between visually induced perceptual illusions of body motion (vection) and visually induced postural responses (VEPRs). Ten standing healthy subjects were tested in two visual conditions known to induce directionally opposite VEPRs: subjects fixated either a static head-mounted or an earth-fixed visual display in front of a horizontally translating visual background.
