Abstract Wide field of view and polarization imaging capabilities are crucial for implementation advanced devices. However, there still great challenges in the integration such optical systems. Here, we report a bionic compound eye metasurface that can realize full Stokes wide view. The consists bifocal metalens array which every three metalenses form subeye. phase is composed gradient hyperbol...

In different endocrine cells of the rat, Smith and interpreted as a cellular mechanism for disposing Farquhar (1) and Orci et al . (2) described the inof excess secretory product under certain expericorporation of secretory granules within lysosomal mental (1) or metabolic conditions (2, 3). Granubodies. This process, called granulolysis (2) or lolysis, at a low rate, is also present under norm...

In the Squilla heart ganglion, the pacemaker is located in the rostral group of cells. After spontaneous firing ceased, the electrophysiological properties of these cells were examined with intracellular electrodes. Cells respond to electrical stimuli with all-or-none action potentials. Direct stimulation by strong currents decreases the size of action potentials. Comparison with action potenti...
