Actinomycosis of the Orbit [PDF]

Ophthalmic Plastic & Reconstructive Surgery, 1992
Actinomycosis is a very rare cause of orbital abscess usually attributable to direct spread from adjacent structures. A case of actinomycosis of the orbit is presented, which was treated as orbital pseudotumour for 3 months before progression of signs and symptoms, despite high dose steroids, led to the diagnosis being reconsidered.

A Study on the Derivation of Atmospheric Water Vapor Based on Dual Frequency Radio Signals and Intersatellite Communication Networks

Aerospace, 2023
The atmospheric total water vapor content (TWVC) affects climate change, weather patterns, and radio signal propagation. Recent techniques such as global navigation satellite systems (GNSS) are used to measure TWVC but with either compromised accuracy ...

Spatially and time-resolved magnetization dynamics driven by spin-orbit torques. [PDF]

Nature Nanotechnology, 2017
Current-induced spin-orbit torques are one of the most effective ways to manipulate the magnetization in spintronic devices, and hold promise for fast switching applications in non-volatile memory and logic units.

Shadowing Lemma and Chaotic Orbit Determination

, 2015
Orbit determination is possible for a chaotic orbit of a dynamical system, given a finite set of observations, provided the initial conditions are at the central time.

Visualizing the invisible: inner plexiform layer stratification with conventional spectral-domain optical coherence tomography

International Journal of Retina and Vitreous
Background The inner plexiform layer (IPL) of the retina plays a key role in visual processing, consisting of five stratified sub-bands (S1-S5) that segregate ON and OFF visual pathways.
