Nystagmus intensities at various gaze angles were studied both preoperatively and postoperatively, using accurate ocular motility recordings, in three cases of congenital nystagmus. In addition to shifting the nystagmus null, the surgery broadened the null region and resulted in an overall reduction in nystagmus intensity at all gaze angles. Surgical rotation also resulted in improved visual ac...

The answer to the main research question on how wildlife is officially classified in South Africa lies in the process of boundary making. Within this work I have dissected boundary making into three particular types of boundaries, namely material boundaries, policy boundaries and imagined boundaries. I noted that the three boundaries are closely related and sometimes overlapping. Stemming from ...

In this work we study the departure for the ideal φ − ω mixing angle in the frame of the Nambu-Jona-Lasinio model. We have shown that in that context, the flavour symmetry breaking is unable to produce the shifting in the mixing angle. We introduce a nonet symmetry breaking in the neutral vector sector to regulate the non-strange content of the φ meson. The phenomenon is well reproduced by our ...

In this paper, the structural behavior of beam joint using bearing bolts was investigated by bending test. From test results, slip against linear that high strength bolts, rotation angle increases with increase clearance bolt holes and decrease depth were confirmed. addition, evaluated accounting for slip, shifting range from contact to pressure state rotational stiffness under pressure.

The excitation of multiple surface-plasmon-polariton (SPP) waves guided by the interface of a metal and a onedimensional photonic crystal in the grating-coupled configuration was studied both experimentally and theoretically. Only p-polarized incident light was considered in the visible and near-infrared regimes. When the absorptance was plotted against the angle of incidence, the excitation of...

We demonstrate an on-chip optical phased array fabricated in a CMOS compatible process with continuous, fast (100 kHz), wide-angle (51°) beam-steering suitable for applications such as low-cost LIDAR systems. The device demonstrates the largest (51°) beam-steering and beam-spacing to date while providing the ability to steer continuously over the entire range. Continuous steering is enabled by ...

The fractional Fourier transform (FrFT) can be thought of as a generalization of the Fourier transform to rotate a signal representation by an arbitrary angle in the time–frequency plane. A lower bound on the uncertainty product of signal representations in two FrFT domains for real signals is obtained, and it is shown that a Gaussian signal achieves the lower bound. The effect of shifting and ...
