Inner dusty regions of protoplanetary discs -- II. Dust dynamics driven by radiation pressure and disc winds [PDF]
, 2020 We explore dust flow in the hottest parts of protoplanetary discs using the forces of gravity, gas drag and radiation pressure. Our main focus is on the optically thin regions of dusty disc, where the dust is exposed to the most extreme heating conditions and dynamical perturbations: the surface of optically thick disc and the inner dust sublimation ...

Acta Ophthalmologica, EarlyView.Abstract Purpose To evaluate choroidal changes in high myopic (HM) patients with posterior staphyloma (PS) and explore their association with Gaussian curvature (K) using ultra‐wide‐field optical coherence tomography angiography (UWF‐OCTA). Methods HM patients with wide macular PS (Type I PS) and without any PS (control) were recruited.

Coexistence of optic disc drusen and idiopathic intracranial hypertension in a non-obese female
Journal of Clinical Ophthalmology and Research, 2015 Idiopathic intracranial hypertension (IIHT) is a headache syndrome characterized by elevated intracranial pressure with normal cerebrospinal fluid (CSF) content, normal neuro imaging with optic disc edema.

Rapid grain growth in post-AGB disc systems from far-infrared and sub-millimetre photometry [PDF]
, 2020 The timescales on which astronomical dust grows remain poorly understood, with important consequences for our understanding of processes like circumstellar disk evolution and planet formation.A number of post-asymptotic giant branch stars are found to host optically thick, dust- and gas-rich circumstellar discs in Keplerian orbits.

In-vivo high resolution imaging of optic nerve head drusen using spectral-domain Optical Coherence Tomography [PDF]
, 2010 Background Optic nerve head drusen (ONHD) are white calcareous deposits, seen either superficially on the optic nerve head or buried within it. Diagnosis of ONHD is made by one or more ways: clinical exam, autofluorescence, ultrasound of the optic nerve,
