    • Embodiments provide techniques for measuring and characterizing the dynamics of cell traction forces. Tunable elastic gel substrates can be disposed in multi-well plates. The gels can be of a uniform predetermined thickness. A multi-well plate can be loaded with gels of different shear moduli. An array of punch indenters can be attached to a loading platen such that the each indenter is aligned to a gel substrate. The indenters can apply tensile or compressive strains to the gel substrates. The magnitude, duration, and frequency of the strain can be controlled by a motor assembly coupled to a control system. The apparatus can be disposed in an incubator for long term cell culture experiments. The cell culture can be observed while a strain is applied. A ring-shaped indenter can be mounted on a microscope, coaxial to the objective lens, and lowered by a calibrated amount onto the underlying gel.
    • 实施例提供了用于测量和表征细胞牵引力的动力学的技术。 可调谐的弹性凝胶基材可以设置在多孔板中。 凝胶可以具有均匀的预定厚度。 多孔板可装载不同剪切模量的凝胶。 可以将一组冲头压头连接到加载压板,使得每个压头与凝胶基板对准。 压痕可以对凝胶基质施加拉伸或压缩应变。 应变的幅度,持续时间和频率可以通过耦合到控制系统的电机组件来控制。 该装置可以放置在用于长期细胞培养实验的培养箱中。 可以在应用菌株时观察细胞培养物。 环形压头可以安装在与物镜同轴的显微镜上,并通过校准量下降到下面的凝胶上。

    • A mobile communication terminal includes a main member and a moving member movably joined to the main member. An antenna connector connects and disconnects an antenna to a PCB according to a movement of the moving member. The antenna connector includes: a rail provided in one of the second member and the first member; a connection member moveable along the rail, the connection member being electrically conductive; and a holder to support the connection member on the rail and to which a first cable extending from one of the antenna and the PCB is connected; and a terminal, disposed adjacent to the rail, of a second cable extending from the other of the antenna and the PCB.
