Retinal meteor

Indian Journal of Ophthalmology, 2017
We describe a case of a 65-year old man diagnosed with retinal vasoproliferative tumour secondary to posterior uveitis. The fluorescein angiography shows an interesting meteor-like leak emanating from the tumour and rising towards the superior retina in the later frames of the angiogram.

Biosynthesis of retinoic acid by intestinal enzymes of the rat

Journal of Lipid Research, 1967
The incubation of Β-carotene-14C with the soluble fraction of the intestinal mucosa resulted in the formation of small amounts of acidic material. The addition of NAD or NADH to the soluble fraction caused a tenfold increase in this material.

Neuromorphic Light‐Responsive Organic Matter for in Materia Reservoir Computing

Advanced Materials, EarlyView.
In this work we show that light‐responsive adaptive organic matter can store and process information at the matter level, and emulate neuromorphic functionalities such as short term memory, long term memory and visual memory. Besides demonstrating that material dynamics can be exploited for spatio‐temporal event detection and motion perception, we show

Additive Manufacturing of Neuromorphic Systems

Advanced Materials, EarlyView.
The crossover of additive Manufacturing (AM) and neuromorphic engineering promises a new paradigm in the fabrication of intelligent hardware—one that is sustainable, scalable, cost‐efficient, and customizable. The AM‐printed neuromorphic hardware (electronics and mechanical systems) is examined, and we discussed the technological integration.
