Erythropoietin "hyporesponders", whose mean ERI of 31.46?IU/kg per week per gram hemoglobin placed them in the lowest decile, had a relative risk for cardiovascular death of 1.7 and an overall relative mortality risk of 1.6, compared with patients who were not receiving EPO ( P ?.001 for both measures). The hyporesponders also had significantly lower body mass indexes and serum albumin levels and higher C-reactive protein levels than patients not taking EPO ( P ?.001 for all).

Dielectric, piezoelectric and electrmechanical coupling properties of PZT and PSZT systems at high Zr content region were studied. The feature of high Kt and low Kp of PZT-based materials near F-AF phase boundary was exploited and examined, and electromachanical coupling anisotropy Kt/Kp is higher than that at the morphotropic phase boundary , Kt≥0.40, Kt/Kp≥3. 0. This phenomenon can be realized by electric field -induced AF-F phase transition and explained by coupling effect of two-sublattice in antiferroelectric unit cell.

However, currently, the retrieval of multiangular remote sensing seldom considers the use of spectral information. We use MSAVI2 as an index to get the a priori knowledge of LAI. As a result, the a priori knowledge is more objective. From the comparison of using or not using this MSAVI predicted a priori knowledge, we found that this approach is effective.

Based on the return map and the principle of closed vectors, a new method is proposed to extract unstable periodic orbits embedded in chaotic attractors. As examples, the UPOs embedded in chaotic attractors of Logistic, Hénon and Lorenz are extracted respectively by this method. And our results of Skewed Hénon map also be compared with Nusse's. These results suggest that this method is valid for unstable periodic orbits from period one to period infinite of arbitrary dimension chaotic system. The dynamic considerations of spiking and UPO coding for individual neuron and neural system under external periodic and chaotic exciting stimulus also be studied in this dissertation. A lot of spiking phenomena, such as synchronization, period, and chaos appear alternatively with the changing of the stimulus frequency. For the small stimulus frequency the neuron could completely convey the periodic signal in synchronous anti-phase into interspike intervals sequences. For the slow time–scale chaotic input, the output two ISI sequences are reciprocally related to input signals, and their oscillation wave shape in time course can be derived from that of the input signals variation, furthermore, the similar input sequence and order of UPOs, distribution of LES and value of KYD remain in attractors reconstructed from ISI sequences.
发现周期信号在单个神经元传递过程中,随着激励频率的改变,神经元输出的峰峰间期interspike interval时间序列呈现出周期、混沌和准周期的交错变化,特别当外加激励信号频率较低时,周期信号可以通过神经元ISI序列以反相同步的周期运动形式传递下去;同时无论是周期还是混沌激励信号,在神经系统中的传递均与其自身强度和神经元之间的耦合强度的大小密切相关;快变时间尺度的混沌激励信号在耦合的神经系统传递过程中,会造成大量基本信息的丢失;而慢变时间尺度的混沌激励信号在神经系统传递中,它的非线性特征信息,如混沌吸引子、不稳定周期轨道、Lyapunov指数谱和分形维数,会通过系统输出的ISI序列部分地重现出来,如与输入慢变时间尺度的混沌激励信号相比,神经系统输出的ISI序列具有:相似几何形状的混沌吸引子、相近的Lyapunov指数谱和分形维数、局部结构相同的不稳定周期轨道的排列方式。
