We measured stereoscopic slant detection thresholds for surfaces slanting about a horizontal or a vertical axis. For random-dot covered surfaces, 1.25 deg of slant was required to detect slant about a horizontal axis, whereas 2.1 deg of slant was required to detect slant about a vertical axis. This anisotropy could be due to the fact that orientation disparities, which contain information about...

objective rubinstein-taybi syndrome is a rare genetic disorder with characteristic featuresincluding downward slanting palpebral fissures, broad thumbs and halluces,and mental retardation. systemic features may involve cardiac, auditory,ophthalmic, endocrine, nervous, renal and respiratory systems. this syndromeis sporadic in nature and has been linked to microdeletion at 16p 13.3 encodingcreb-...

BACKGROUND Patients with 'A' or 'V' pattern esotropia without vertical muscle overaction have traditionally been treated with medial rectus recession and vertical transposition of the muscle insertions. METHOD Seven cases are presented treated by slanting muscle insertions, whereby the lower margin of the medial rectus is preferentially recessed more than the upper margin in esotropia, and th...

A new Arabidopsis thaliana (L.) Heynh. root mutant, named clg1, was isolated from the Feldmann-Du Pont T-DNA insertional mutagenesis collection. It is characterized by primary roots that make early right-handed coils, show increased right-handed slanting, and reduced positive gravitropism. The mutant roots however did not exhibit increased resistance to IAA, but only a modest increment of resis...

Roots of wild-type Arabidopsis thaliana seedlings in the Wassilewskija (WS) and Landsberg erecta (Ler) ecotypes often grow aslant on vertical agar surfaces. Slanted root growth always occurs to the right of the gravity vector when the root is viewed through the agar surface, and is not observed in the Columbia ecotype. Right-slanted root growth is surface-dependent and does not result directly ...

The local defect correction (LDC) method is used to solve a convection-diffusion-reaction problem that contains a high activity region in a relatively small part of the domain. The improvement of the solution on a coarse grid is obtained by introducing a correction term computed from a local fine grid solution. This paper studies problems where the high activity region is covered with a rectang...

Automated optical inspection is a very important technique. For this reason, this study proposes an optical non-contact slanting surface measuring system. The essential features of the measurement system are obtained through simulations using the optical design software Zemax. The actual propagation of laser beams within the measurement system is traced by using a homogeneous transformation mat...
