Rolling-based seismic isolation systems, in which rollers of circular or non-circular section are used, are less expensive and easier to manufacture. However, this type of isolation suffers from either lack of restoring or re-centering capability, or weakness against uplift forces. To resolve the first shortcoming the use of elliptical as well as pillow-shape rolling parts has been suggested, a...

Cameras with rolling shutters are becoming more common as low-power, low-cost CMOS sensors are being used more frequently in cameras. The rolling shutter means that not all scanlines are exposed over the same time interval. The effects of a rolling shutter are noticeable when either the camera or objects in the scene are moving and can lead to systematic biases in projection estimation. We deve...

The present study examined the development of the axonal torpedoes of the cerebellar Purkinje cells in a Cav2.1 channel mutant, rolling mouse Nagoya. Calbindin D-28k immunostaining revealed a few torpedoes in both the cerebellar white matter and all three subdivisions of the deep cerebellar nuclei of rolling mice on postnatal day (PD) 21, while there was no difference in either number among the...

The present paper analyzes the existence of a long-run relationship between the trade balance and exchange rate of Iran and South Korea by a new approach. It proposes an asymmetric co-integrating NARDL model by two positive and negative partial sum decompositions which can use mixed I (0) and I (1) variables by bounds testing approach. The proposed tests are based on calculated F –statistics an...

We report the design and synthesis of nanorotors based upon on-wire lithography. Because of their asymmetric structure, the nanorotors exhibit rotation in a H2O2 bath instead of linear motion. By observing the leading edge of rotation and comparing this result to the nanorotor design, we have concluded that the driving force for motion is dynamic catalytic decomposition of H2O2 which propels, r...
