Neuropathic pain was produced by chronic constriction injury of the sciatic nerve in rats. Behaviora tests showed that the thresholds for thermal and mechanical hyperalgesia were significantly reduced in neuropathic pain rats 3 28 days following model induction. The results of immunohistochemistry, western blot assays and reverse transcription-PCR showed that Nay1.7 protein and mRNA expression was significantly increased in the injured dorsal root ganglia. These findings indicated that Nay1.7 might play an important role in the model of chronic neuropathic pain

讨论了利用Zernike矩描述对称结构模态振型的方法,通过对结构的模态振型数据进行Zernike矩变换,将其分解成一系列Zernike矩的线性组合,而每一个Zernike矩反映模态振型的一部分形状特征。不同特征矩的线性组合,可以代表各阶模态的振型。在此基础上进一步提出了确定Zernike多项式最高阶数的方法,并讨论了Zernike矩描述对称结构模态振型的方法及其去噪声的能力。通过对简单圆盘结构的仿真实例研究,验证了应用Zernike矩描述对称结构模态振型的优越性。结果表明:利用Zernike矩描述对称结构的模态振型可以更有效地描述对称结构的模态,包括重模态,同时还能有效地消除测试数据中噪声的影响,对进一步实现对称结构有限元模型修正和模型确认具有重要的应用价值。

Improving zinc metal(Zn^(0))reversibility and minimizing the N/P ratio are critical to boosting the energy density of Zn^(0) ***,in reality,an excess Zn source is usually adopted to offset the irreversible zinc loss and guarantee sufficient zinc cycling,which sacrifices the energy density and leads to poor practicability of Zn^(0) *** address the above conundrum,here,we report a lean-Zn and hierarchical anode based on metal-organic framework(MOF)-derived carbon,where trace Zn^(0) is pre-reserved within the anode structure to make up for any irreversible zinc source *** allows us to construct low N/P ratio Zn^(0) full cells when coupling the lean-Zn anode with Zn-containing ***,high Zn^(0) reversibility(average Coulombic efficiency of 99.4% for 3000 cycles)and long full-cell lifetime(92% capacity retention after 900 cycles)were realized even under the harsh lean-Zn condition(N/P ratio:1.34).The excellent Zn reversibility is attributed to the hierarchy structure that homogenizes zinc ion flux and electric field distribution,as confirmed by theoretical simulations,which therefore stabilizes Zn^(0) *** lean-Zn anode design strategy will provide new insights into construction of high-energy Zn^(0) batteries for practical applications.

This paper proposes a chip correlation indicator （CCI）-based link quality estimation mechanism for wireless sensor networks under non-perceived packet loss. On the basis of analyzing all related factors, it can be concluded that signal-to-noise rate （SNR） is the main factor causing the non-perceived packet loss. In this paper, the relationship model between CCI and non-perceived packet loss rate （NPLR） is established from related models such as SNR versus packet success rate （PSR）, CCI versus SNR and CCI-NPLR. Due to the large fluctuating range of the raw CCI, Kalman filter is introduced to do de-noising of the raw CCI. The cubic model and the least squares method are employed to fit the relationship between CCI and SNR. In the experiments, many groups of comparison have been conducted and the results show that the proposed mechanism can achieve more accurate measurement of the non-perceived packet loss than existing approaches. Moreover, it has the advantage of decreasing extra energy consumption caused by sending large number of probe packets.

With the rapid evolution of WSNs technology, it is very important to evaluate link quality quickly and accurately, so that the routing protocols can take relevant strategies in time to keep the entire network working steadily and efficiently. However, the issue of layer is still open to research. To tackle this issue, a improving link quality assessment methods on physical novel link quality assessment metric called S3LQA is proposed, which estimates the link quality of wireless sensor networks by CC2420 wireless radio frequency transceiver principles and free space propagation theory. The metric adopts both complete and incomplete packages to improve the evaluation performance effectively based on IEEE802. 15.4 frame format and DSSS-O- QPSK mechanism. The experimental results show that the proposed method can improve energy cost and achieves hatter real-timin nerformance than traditional counting-based （PRR） link aualitv assessment metric.
