We consider the Vlasov–Poisson–Ampère system of equations, and we seek solutions for the electric field E(x ,t) that are periodic in space and asymptotically almost periodic in time. Introducing the representation E(x ,t)5T(x ,t)1A(x ,t) ~where T and A are, respectively, the transient and time-asymptotic parts of E! enables us to decompose the nonlinear Poisson equation into a transient equatio...

We have tested whether affinity-matured TCRs that retain peptide specificity improve the ability of primary human CD8(+) T cells to mount antigen-specific responses. We found that TCR affinity correlated with the speed of T-cell responses. High affinity TCR-antigen interactions rapidly initiated T-cell responses, but low affinity TCR/antigen interactions required longer time periods to elicit t...

Background: Multiple sclerosis (MS) is an autoimmune disease of the central nervous system. Psychological manifestations such as depression, anxiety and stress are common in patients with MS. Social support is involved in the well-being of patients with MS. This study aimed to assess the relation between perceived social support with depression, anxiety and stress in patients with MS. Methods:...

One of the goals of organic crop production is to grow species which combinetraditional pro-healthy properties, innovative cultivation practices and harmonywith the environment. Among the ancient species the spring spelt is especiallypredisposed for organic farming. In comparison with common wheat spring spelthas a relatively short research history on physiological analysis of growth anddevelop...

We start from the observation that Zadeh’s compositional rule of inference (CRI) is a strategy to determine approximately a roughly given control function. From this point of view the problem to solve a system of fuzzy relation equations also becomes the problem to determine approximately such a control strategy. This gives a natural interpretation for approximate solutions of unsolvable system...
