An efficient actuation method for millimetric droplets is described: Single are driven on a liquid infused surface by small bead that acts as carrier, like rickshaw. When the moved at fixed velocity droplet follows its trajectory, up to critical value of which and lose contact. The predicted from balance between bead/droplet adhesion force friction acting where it in contact with substrate.

A one-trial learning task, where chicks learn that a bead of a particular shape and/or colour has a bitter taste (because it has been coated in 100% methyl anthranilate, MeA) and subsequently avoids it on test, has been widely used by research groups across the world. However, there are some differences in the results reported by different research laboratories. One important difference is foun...

We describe an apparatus that combines microelectrophoresis and laser trap technologies to monitor the activity of phosphoinositide-specific phospholipase C-delta1 (PLC-delta) on a single bilayer-coated silica bead with a time resolution of approximately 1 s. A 1-microm-diameter bead was coated with a phospholipid bilayer composed of electrically neutral phosphatidylcholine (PC) and negatively ...

The measurement of modulation transfer functions (MTFs) in computed tomography (CT) is often performed by scanning a point source phantom such as a thin wire or a microbead. In these methods the region of interest (ROI) is generally placed on the scanned image to crop the point source response. The aim of the present study was to examine the effect of ROI size on MTF measurement, and to optimiz...

We have examined a new method for generating coarse-grained models of polymers. The resulting models consist of bead-spring chains with the spring force law taken from the force-extension behavior in the constant extension ensemble. This method, called the polymer ensemble transformation method, is applied to the freely jointed chain. The resulting model illustrates why current bead-spring chai...
