The tumor suppressor p53.mediates the cellular response to various stresses. It was experimentally shown that the concentration of p53.can show oscillations with short or long periods upon DNA damage. The underlying mechanism for this phenomenon is still not fully understood. Here, we construct a network model comprising the ATM-p53.Wip1 and p53.Mdm2 negative feedback loops and ATM autoactivation. We recapitulate the typical features of p53.oscillations including p53.birhythmicity. We show the dependence of p53.birhythmicity on various factors such as the phosphorylation status of ATM. We also perform stochastic simulation and find the noise-induced transitions between two modes of p53.oscillation, which increases the p53.variability in both the amplitude and period. These results suggest that p53.birhythmicity enhances the responsiveness of p53.network, which may facilitate its tumor suppressive function.

对已经取得较普遍应用的Si体太阳电池来说,开发新技术以降低电池的制造成本是目前该领域最重要的努力方向之一。尽管通过优化制造工艺可以在一定程度上进一进降低单晶Si和多晶Si体太阳电池的成本,但要进一大幅度地降低Si太阳电池的成本似乎是只能依赖于新一代的多晶Si薄膜电池。多晶Si薄膜电池因其转换效率高、寿命长和工艺简化等优点而极具潜力。本文从材料制备、材料性能和有关工艺等方面对多晶Si薄膜太阳电池的发展现状作了介绍。

We calculate the magnetic properties of small Fe N clusters( N =2～7,9,13.15) by using a parameterized Hubbard tight binding spd band model Hamiltonian, with the parameters obtained from nonorthogonal Hamiltonian parameters. the average magnetic moments, and the spin polarized charge distribution within clusters are in agreement with those obtained by first principle and tight binding calculations. The effect of the nonorthogonal basis is discussed.
