Background & Aims: The orbital cavity is an important anatomic structure in the face. It is in close connection with the skull, paranasal sinuses, and the nose. Precise knowledge of the orbital cavity dimensions can be helpful in the diagnosis and treatment of diseases associated with the orbital cavity. Due to the lack of adequate research on orbital size in Iran and the city of Kerman, the ai...

Tsiganis et al. [Tsiganis, K., et al., 2005. Nature 435, 459–461] have proposed that the current orbital architecture of the outer solar system could have been established if it was initially compact and Jupiter and Saturn crossed the 2:1 orbital resonance by divergent migration. The crossing led to close encounters among the giant planets, but the orbital eccentricities and inclinations were d...

Gravitational wave detection experiments in space, including satellite Doppler-Tracking (Bertotti and Iess, 1999) and LISA (http://lisa.jpl.nasa.gov), will hopefully open a window on the low-frequency part of the gravitational wave (henceforth GW) spectrum of cosmic origin. In these frequency bands, binary stars are among the most promising continuous detectable source. A substantial fraction o...

PURPOSE To identify and explain the effects of eye and head position on smooth pursuit eye movements in normal humans. METHODS Horizontal and vertical smooth pursuit were measured in different eye-in-orbit positions in normal subjects, using a magnetic search coil technique with sinusoidal and step-ramp stimuli. Pursuit also was tested in different horizontal head-on-trunk positions. RESULT...

orbital lynphangioma is a low-flow or no-flow vascular malformation. it is a congenital and isolated hemodynamic lesion in which the clinical presentation and onset are related to orbital, peri-orbital or intracranial involvement. in addition, history of previous trauma and upper respiratory tract infection are important predictor factors. high resolution mri, doppler ultrasound and ct-scan are...

We present modeling results for the reprocessed radiation expected from magnetic flares above AGN accretion disks. Relativistic corrections for the orbital motion of the flare and for the curved space-time in the vicinity of the black hole are taken into account. We investigate the local emission spectra, as seen in a frame co-orbiting with the disk, and the observed spectra at infinity. We inv...

We show, assuming a mild set-theoretic hypothesis, that if an abstract elementary class (AEC) has a superstable-like forking notion for models of cardinality λ and a superstable-like forking notion for models of cardinality λ+, then orbital types over models of cardinality λ+ are determined by their restrictions to submodels of cardinality λ. By a superstable-like forking notion, we mean here a...

Palaeomagnetism of climatically sensitive sedimentary rock types, such as glacial deposits and evaporites, can test the uniformitarianism of ancient geomagnetic fields and palaeoclimate zones. Proterozoic glacial deposits laid down in near-equatorial palaeomagnetic latitudes can be explained by ‘snowball Earth’ episodes, high orbital obliquity or markedly non-uniformitarian geomagnetic fields. ...

This paper identifies and analyzes stable sun-synchronous orbits in aHill rotating frame that can be applied to any small body in the solar system. The stability of these orbits is due to the inclusion of solar radiation pressure effects. The stability of the orbits from escaping the comet are analyzed using the construction of zero-velocity curves for the system considered as well as spectral ...
