A new apparent relativistic paradox is presented involving only one space-time event. This different from earlier ‘relativistic paradoxes' extended bodies or events at positions. collision between a rod and ring impacting an oblique angle to each other considered in the context of special theory relativity. question arises as where along length point impact will be according two observers inert...

Rod signals in the mammalian retina are thought to reach ganglion cells over the circuit rod-->rod depolarizing bipolar cell-->AII amacrine cell-->cone bipolar cells-->ganglion cells. A possible alternative pathway involves gap junctions linking the rods and cones, the circuit being rod-->cone-->cone bipolar cells-->ganglion cells. It is not clear whether this second pathway indeed relays rod s...

In vitro generation of photoreceptors from stem cells is of great interest for the development of regenerative medicine approaches for patients affected by retinal degeneration and for high throughput drug screens for these diseases. In this study, we show unprecedented high percentages of rod-fated cells from retinal stem cells of the adult ciliary epithelium. Molecular characterization of rod...

In this paper, KENOV.a module of SCALE code system was used to perform Monte Carlo simulation of the TRIGA MARK II research reactor benchmark experiments [1,2] in steady state operation conditions. Robert Jeraj and his coworkers have presented a similar simulation of the TRIGA MARK II research reactor benchmark experiments via MCNP4A in 1997. [3] The core excess reactivity measurement experimen...

Current understanding suggests that mammalian rod photoreceptors connect only to an ON-type bipolar cell. This rod-specific bipolar cell excites the All amacrine cell, which makes connections to cone-specific bipolar cells of both ON and OFF type; these, in turn, synapse with ganglion cells. Recent work on rabbit retina has shown that rod signals can also reach ganglion cells without passing th...
