Comprehensive Summary,Great efforts have been lately devoted to fabricating well-defined nanostructures using crystallization-driven self-assembly(CDSA)*** influence of self-assembly on crystallization is also of great ***,a series of amphiphilic diblock copolypeptoids poly(N-allylglycine)-b-poly(N-octylglycine)modified with cysteamine hydrochloride((PNAG-g-NH_(2))-b-PNOG)were synthesized by ring-opening polymerization(ROP)and post-polymerization *** diblock copolypeptoid is comprised of one hydrophobic crystalline PNOG block and one hydrophilic amorphous block,which can aggregate into nanostructured assemblies with soluble PNAG-g-NH_(2) as the corona layer and PNOG as the inner core in aqueous *** a systematic study by differential scanning calorimetry(DSC)and wide-angle X-ray scattering(WAXS),we demonstrated that the self-assembly of the block copolymers strengthens the crystallization of the PNOG block.

作者： HUANG Shuigen lin min WANG Ruoyu CHEN Zhuojun DONG Yemin Shanghai Institute of Microsystem and Information Technology Chinese Academy of Sciences Shanghai University

A fully-integrated 400MHz transceiver for high definition video transmission in Unmanned aerial vehicle（UAV） is presented. The transceiver integrates a Receiver（RX）, a Transmitter（TX）, a tunable multi-mode complex filter, two sigma-delta fractional-N PLL frequency synthesizers and some baseband calibration circuits, which is applicable for both Time division duplex（TDD） and Frequency division duplex（FDD） systems. In order to meet different data rate and sensitivity requirements for control signal and video signal transmission, the transceiver supports BPSK/QPSK/QAM *** receiver sensitivity is –75dBm and the transmitter provides emission power up to 12dBm. Besides, the Error vector magnitude（EVM） of –35dB is measured under 64QAM modulation with 54Mbps data *** in a standard 130nm CMOS process and operated at 1.2V supply for most circuits excluding PA,3.3V supply for PA, the receiver and the transmitter consume 68.2mW and 164.3mW, including the frequency synthesizer, respectively. The total chip area with pads is 6.25 mm;.

寒冷地区海上风机结构受到复杂环境荷载作用,易出现振动安全性问题。文章以某6.45 MW海上单桩风机结构为例,施加风、冰荷载联合作用,对比分析多重调谐质量阻尼器(MTMD)系统减振前后的结构振动响应。结果表明:风、冰荷载会引起风机塔架的剧烈振动响应,最大位移响应出现在风机塔顶,最大加速度响应出现在结构二阶振型幅值点附近;除了前两阶频率,风、冰荷载还会激起塔架结构的更高阶响应;同时控制结构一二阶频率的MTMD方案可有效控制塔架位移、加速度和倾覆力矩响应,减振效果明显,但调谐质量阻尼器(TMD)装置存在频率敏感性,无法控制更高阶频率引起的结构振动响应。

Pd作为高活性的贵金属催化剂广泛用于铃木偶联反应等有机反应。为提高Pd催化剂对铃木偶联反应的催化性能,采用具有光热效应的MoS_(2)作为载体,设计并制备Pd/MoS_(2)复合纳米催化剂。首先通过水热法合成MoS_(2)花状超结构,该结构由纳米片(片径为200~300 nm,厚度约为7 nm)组装而成。利用还原法在MoS_(2)花状超结构的表面负载Pd纳米颗粒,其直径约为11 nm。随后,以Pd/MoS_(2)花状超结构为催化剂研究了激光加热和油浴加热两种条件下的铃木偶联反应效率。随着波长808 nm的激光的强度从1增加到4 W/cm^(2),激光加热使溶液平衡温度从29.4升高到60.8℃,相应的光热催化产率从30.5%提高到86.3%,明显高于油浴加热同等温度下的热催化产率(24.3%~60.4%)。当反应温度为40℃时,光热催化速率是热催化的1.5倍。综上,Pd/MoS_(2)花状超结构展现了较好的光热催化性能,为设计高活性的铃木偶联反应催化剂提供了新思路。

A simple model for a set of interacting idealized neurons in scale-free networks is introduced. The basic elements of the model are endowed with the main features of a neuron function. We find that our model displays powerlaw behavior of avalanche sizes and generates long-range temporal correlation. More importantly, we find different dynamical behavior for nodes with different connectivity in the scale-free networks.

A simple model for a set of integrate-and-fire neurons based on the weighted network is introduced. By considering the neurobiological phenomenon in brain development and the difference of the synaptic strength, we construct weighted networks develop with link additions and followed by selective edge removal. The network exhibits the small-world and scale-free properties with high network efficiency. The model displays an avalanche activity on a power-law distribution. We investigate the effect of selective edge removal and the neuron refractory period on the self-organized criticality of the system.

A modified evolution model of self-organized criticality on generalized Barabasi-Albert （GBA）.scale-free networks is investigated. In our model, we find that spatial and temporal correlations exhibit critical behaviors. More importantly, these critical behaviors change with the parameter b, which weights the distance in comparison with the degree in the GBA network evolution.
