Functional additives have recently been regarded as emerging candidates to improve the performance and stability of perovskite solar cells(PSCs).Herein,nicotinamide(N),2-chloronicotinamide(2Cl),and 6-chloronicotinamide(6Cl)were employed as O-ligands to facilitate the deposition of MAPbI_(3)(MA=methylammonium)and MA-free FA_(0.88)Cs_(0.12)PbI_(2.64)Br_(0.36)(FA=formamidinium)perovskite films by multifunctional *** density functional theory(DFT)calculations and ultraviolet photoelectron spectroscopy(UPS)measurements,it is identified that the highest occupied molecular orbital(HOMO)level for additive modified MAPbI_(3)perovskite could reduce the voltage deficit for hole ***,due to the most favorable charge distribution and significant improvements in charge mobility and defect passivation,the power conversion efficiency(PCE)of 2Cl-MAPbI_(3)PSCs was significantly improved from 19.32%to 21.12%.More importantly,the two-dimensional grazing-incidence wide-angle X-ray scattering(GIWAXS)analysis showed that PbI_(2) defects were effectively suppressed and femtosecond transient absorption(TA)spectroscopy demonstrated that the trap-assisted recombination at grain boundaries was effectively inhibited in the 2Cl-MA-free *** a result,the thermally stable 2Cl-MA-free PSCs achieved a remarkable PCE of 23.13%with an open-circuit voltage(V_(oc))of 1.164 V and an ultrahigh fill factor(FF)of 85.7%.Our work offers a practical strategy for further commercializing stable and efficient PSCs.

Myocardial bridge （MB） is regarded as a common .anatomic variant rather than a congenital conditionanomaly, defined as the intrainyocardial course of a portion of the coronary artery. It was first mentioned by Rayman in 1737 and first described by Grainicianu in the early 1920s. The current gold standard tor diagnosing MB is coronary angiography with the typical systolic compression of the epicardial coronary vessel （milking effect）.

Functional Characterization of CRISPR-Cas System in the Ethanologenic Bacterium Zymomonas mobilis ZM4

Advances in Microbiology 2016年第3期6卷 178-189页

作者： ge Dong Mingxiong He Hong Feng Sichuan Key Laboratory of Molecular Biology and Biotechnology The Key Laboratory for Bio-Resources and Eco-Environment of the Ministry of Education College of Life Sciences Sichuan University Chengdu China Biomass Energy Technology Research Center Biogas Institute of Ministry of Agriculture Chengdu China

CRISPR-Cas (clustered regularly interspaced short palindromic repeats—CRISPR associated proteins) is a RNA-guided defense immune system that prevents some genetic elements such as plasmids and virus from getting into the bacterial cells. Zymomonas mobilis is an ethanologenic bacterium, which encodes a subtype I-F CRISPR-Cas system containing three CRISPR loci and a far distant cas gene cluster. Reverse transcription (RT)-PCR analysis revealed that the CRISPR loci were transcribed on both strands. The Cas proteins were suggested to be expressed based on the previous transcriptomic analysis. Challenging with the invader plasmids containing the artificial protospacer with the protospacer adjacent motif (PAM) of NGG or GG exhibited immune interference activity. However, PAM motif of GG seems more effective than NGG in interference activity. Further, the artificial CRISPR arrays with the spacer sequences targeting to the specific genome sites could also lead to strong immune activity, resulting in almost no transformant grown on the agar plates. It was suggested that bacteria like Z. mobilis ZM4 are lack of the rejoining function to heal the double breakage of genomic DNA made by the CRISPR system. Conclusively, the Type I-F CRISPR-Cas system in Z. mobilis ZM4 is active to functionally defense the invading DNA elements.

随着数字信息与云存储技术的发展与成熟,密文域可逆信息隐藏算法正逐渐成为通信传输中数据隐私保护的研究热点。如何根据不同载体图像像素的分布特征,对局部区域内像素进行自适应识别编码,实现对载体更彻底的压缩以提升嵌入容量仍具有较大挑战。本文针对密文域可逆信息隐藏算法因载体图像冗余空间压缩不充分而导致嵌入容量较低的问题,提出一种基于差分编码和块压缩的密文域可逆信息隐藏算法。首先,根据自然图像局部区域内像素强相关性邻位作差,并基于块内最大差值对差值图像矩阵进行分类和自适应编码,同时设计分块置乱和块内像素扩散加密机制保证图像信息安全。然后,将自适应编码结果在对应的密文图像块上进行标记,压缩冗余空间。最后,通过位替换嵌入秘密信息。不同于其他算法,本算法对差分编码后的图像进行比特位重排列,从密文图像像素最低有效位开始,标记差值像素的符号位,其余各位面依次标记最小差值比特位。由于加密操作与自适应编码的可逆性,合法接收者可实现对原始明文图像的无损重构和秘密信息的无误提取。实验结果表明,与现有的几类算法相比,本文提出的算法具有更高的嵌入率和更好的安全性,在BOSSbase和BOWS-2两个数据集上的平均嵌入率达到3.027位/像素和2.937位/像素,在测试图像上平均嵌入率也均提高了0.57位/像素以上。

Left ventricular hypertrophy in relation to systolic blood pressure and the angiotensin converting enzyme I/D polymorphism in Chinese

Journal of geriatric Cardiology 2009年第3期6卷 131-136页

作者： Alexander P. Headley Yan Li Yi Zhang Ji-Yong ge Qi-Fang Huang Ji-Guang Wang Centre for Epidemiological Studies and Clinical Trials Ruijin Hospital Shanghai Jiaotong University School of Medicine Shanghai 200025 China

Objective There is little population-based data on the prevalence and the environmental or genetic determinants of left ventricular hypertrophy （LVH） in China. The purpose of this paper is to study LVH in relation to systolic blood pressure and the angiotensin converting enzyme （ACE） insertion/deletion（I/D） polymorphism in Chinese. Methods We recorded 12- lead ECG （CardioSoft, v4.2） in 1365 residents in the Jingning County, Zhejiang Province, China. LVH was defined according to the gender-specific Sokolow-Lyon and Cornell product ECG criteria. Results Regardless of whether the Sokolow-Lyon or Cornell product ECG criteria was used, the prevalence of LVH （20.7% and 4.8%, respectively） significantly （P〈0.0001） increased with male gender （odds ratio [OR] 2.33 and 7.15） and systolic blood pressure （per 10 mm Hg increase, OR 1.46 and 1.33）. If the Sokolow-Lyon criteria was used, the prevalence of LVH was also influenced by alcohol intake （OR 1.44, P=-0.03） and body mass index （OR 0.83, P=0.0005）. The association between the Sokolow-Lyon voltage amplitude and the ACE I/D polymorphism was dependent on antihypertensive therapy （P=0.01）. In 1262 untreated subjects, but not 103 patients on antihypertensive medication, the ACE DD compared with II subjects had significantly higher Sokolow-Lyon voltage amplitudes （29.8：-0.6 vs. 28.0-3：0.5 mV, P=-0.02） and higher risk of LVH （OR 1.74, 95% CI： 1.12-2.69, P=-0.01）. Conclusion LVH is prevalent in Chinese, and is associated with systolic blood pressure and the ACE D allele. The genetic association might be modulated by antihypertensive therapy（J geriatr Cardio12009; 6：131-136）.

微震震源定位受定位方法、微震台网布置、波速模型和到时等因素的影响,单一指标很难对震源定位结果进行全面评价,因此提出了一种包含事件残差指标、敏感度指标和触发序列指标的震源定位可靠性综合评价方法。采用改进的L1范数统计准则计算微震事件残差,并根据事件残差的取值范围确定了可评价震源定位精度的事件残差指标;根据给定波速误差后震源定位结果之间差值的大小,提出了敏感度指标,主要对定位稳定性进行评价;基于观测触发序列和计算触发序列匹配度,并结合微震台网布置和有效传感器数量,提出了触发序列指标,该指标能够同时反映定位精度和稳定性;综合以上3种评价指标,建立了微震震源定位可靠性综合评价模型。通过现场试验验证,表明该模型能够对定位精度和稳定性进行全面有效评价,评价结果可以作为衡量微震监测系统定位可靠性的实用依据。
