在当代商业与科技语境中,传统静态标识设计越来越多地向动态设计延展。在视觉传播中,静态与动态设计随环境不同而各具优势弊端。但根本上,二者还是在形式层面上的观照,并未触及数字媒介统领时代标识设计的责任与文化内涵。在此背景下,费城艺术博物馆的"开放性"标识为设计、艺术与公众之间建立了一种连接关系,为设计与文化的相互介入提供一种新的可能性。

Background Extensive research toward creating a biological pacemaker by enhancement of inward depolarizing current has been performed. However, studies have mainly focused on inducing spontaneous activity and have not adequately addressed ways to improve pacemaker function. In this study we attempted to improve pacemaker function by altering connexin expression in rat mesenchymal stem cells （MSCs） to a phenotype similar to native sinus node pacemaker cells. Methods To generate a biological pacemaker, MSCs were transduced with a cardiac pacemaker gene- hyperpolarization-activated cyclic nucleotide-gated channel 4 （HCN4）, via transfection with a lentiviral vector. Funny current （If） in HCN4~ MSCs was recorded by voltage-clamp. Overexpression of connexin 45 （gene Gja7） in MSCs was achieved by transfection with the plasmid pDsRED2-N1-Gja7-RFP. Double-immunolabelling with anti-connexin 43 and anti-connexin 45 antibodies were used to identify the gap junction channels. The effects of the genetically modified MSCs on cardiomyocyte excitability were determined in MSCs cocultured with neonatal rat ventricular myocytes. Spontaneous action potentials of neonatal rat ventricular myocytes were recorded by current-clamp. Results High level time- and voltage-dependent inward hyperpolarization current that was sensitive to 4 mmol/L Cs＋ was detected in HCN4＋ MSCs, confirming that HCN4 acted as Ir channels in MSCs. Connexin 43 and connexin 45 were simultaneously detected in CX45＋ MSCs. Beating frequency was （82±8） beats per minute （n=-5） in myocytes cocultured with non-transfected control MSCs, versus （129±11） beats per minute （n=-5） in myocytes cocultured with HCN4＋ MSCs. Myocytes cocultured with MSCs cotransfected with HCN4 and connexin 45 had the highest beating frequency at （147±9） beats per minute （n=5）. Conclusion These findings demonstrate that overexpression of connexin 45 and subsequent formation of heteromeric connexin 45/connexin 43 gap junction channels in HCN4 expressing

在分析车辆荷载对沥青面层结构作用模式的基础上,设计了沥青混合料同轴剪切重复荷载试验,提出以剪切回弹模量和塑弹比为评价指标来判别沥青混合料剪切变形特性.基于3种沥青、2种级配混合料的同轴剪切重复荷载试验结果,评判剪切回弹模量与塑弹比指标的合理性,分析它们的影响因素及变化规律.结果表明:剪切回弹模量与塑弹比指标可以反映沥青混合料剪切变形黏弹性本质特征,并与混合料动稳定度存在良好的相关性;采用改性沥青、增大沥青混合料最大公称粒径、降低峰值荷载、缩短荷载周期,将提高沥青混合料剪切回弹模量、降低塑弹比.

Background, Motivation and Objective Drilling causes variation of the rock properties in the vicinity of a wellbore. Usually, acoustic velocities, including P-and S-wave ones near the borehole wall are smaller than those of the virgin formation. In order to understand the velocity profile along the borehole radial direction for formation characterizations, we investigate the influence of the thickness of the transition zone on monopole longitudinal waves at varying source-to-receiver separations and frequency range based on the radial stepped sonic model. This research may be applied for radial tomography of longitudinal wave velocity with monopole logging tools. Statement of Contribution/Methods In this article, we use the radial cylindrical layered model to examine monopole logging response with a two-dimensional axisymmetric finite difference method. Three variables are set, and they are the transition zone thickness, the source frequency and source-to-receiver spacing, respectively. We also use the slowness-time correlation-method to evaluate sound speed variations under different conditions. At last, based on the ray theory, the variation characteristics of the arrival time of the first wave under different conditions are analyzed. Results For a certain source-to-receiver offset, there is a critical value for the intermediate layer thickness. When the intermediate layer thickness is less than that value, the first wave is the outermost layer formation compressional wave. When the intermediate layer thickness is greater than that value, the first wave is the compressional wave of the formation closest to the wellbore. The longitudinal waves sliding along different interfaces can be separated from each other in the time domain with the appropriate source to receiver offset. According to this result, one can possibly obtain different speeds of the intermediate layers. Meanwhile, the first wave amplitude is gradually weakened as the spacing increases. For sources w
