An acidic solution based method towards flexible lithium ion battery(LIB)cathodes is developed in this work with perylene diimide(PDI)as the electroactive component and carbon cloth(CC)as the current *** this approach,PDI is firstly dispersed in concentrated sulfuric acid(H2S04)and then deposited on CC substrate after the dilution of H2S04,which provides an organic solvent-free strategy to construct integrated LIB *** acdic solution based fabrication process also allows the facile adjusting of loading amounts of PDI in the cathodes,which can effectively influence the battery performances of the PDI/CC *** the result,the acidic solution processed PDI/CC cathode can deliver a high specific capacity of-36 mAh·g^-1 at the current density of 50 mA·g^-1 in both half cell with lithium foil as anode and full cell with pre-lithiated CC as *** both types of the batteries,the PDI/CC cathodes show good cycling stabilities by retaining^84%of the initial capacities after 300 charge-discharge cycles at 500 mA·g^-***,the excellent mechanical stability of the PDI/CC cathode enables the LIBs in pouch cell to maintain the electrochemical performances under various bending states,demonstrating their potentials for flexible LIBs.

Background： Patients with Alzheimer＇s disease （AD） manifest progressive decline in writing abilities. Most studies on agraphia in AD have been performed in the alphabetic system, such as English. However, these findings may not be applicable to other written language systems. The unique features of the Chinese written script could affect the patterns of agraphia in Chinese AD patients. The aim of this study was to explore the features of writing errors in Chinese patients with AD and amnestie mild cognitive impairment （a-MCI）, as well as to study the relationship between their writing errors and neuropsychological functions. Methods： In this study, we performed an observational study in a group of subjects including 17 AD patients, 14 patients with a-MCI, and 16 elderly healthy controls. We analyzed the writing errors in these subjects and also studied the relationship between their writing errors and neuropsychological functions. Results： Our study showed that in patients whose mother tongue is Chinese, writing ability was comparatively well preserved in the MCI phase but significantly impaired when the disease progressed to the stage of AD. The writing errors showed corresponding increase with the severity of cognition decline, both in the types of errors and rate of occurrence. Analysis of the writing errors showed that word substitution and unintelligible words were the most frequent error types that occurred in all the three study groups. The occurrence rate of unintelligible words was significantly higher in the AD group compared with the a-MCI group （P = 0.024） and control group （P = 0.018）. In addition, the occurrence rates of word substitution were also significantly higher in AD （P = 0.013） and a-MCI groups （P = 0.037） than that of control group. However, errors such as totally no response, visuospatial impairment, paragraph agraphia, ideograph, and perseverative writing errors were only seen in AD group. Besides, we also found a high occurrence rate of vi

研究了一种低计算量的宽带最小方差无畸变波束形成(MVDR)算法,利用频移和线性相位FIR低通滤波对阵列接收信号的复包络作窄带分解,对各子带信号的基带信号作最小方差波束形成,所以可将原始信号的采样频率降到接近处理频段的带宽大小,选择信号主要能量频带,可以减少处理子带个数,大大降低了运算量。仿真和湖试数据分析结果证明了该方法的有效性,且对弱目标分辨性能较好。
