TV synchronization system features stability and noise immunity [PDF]
, 1967 Horizontal jitter in the video presentation in television systems is prevented by using an additional sync level. This circuitry uses simultaneous signals at both sync and porch frequencies, providing a sync identification from which a coincidence ...

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

Flexible Selenium Nanowires with Tuneable Electronic Bandgaps
Advanced Materials, EarlyView.Nanotubes serve as effective test tubes for selenium nanowires, as their diameter precisely controls the width of the nanowires and the Se─Se bonding, resulting in a variety of different structures. An electron beam can be used to modify the nanotubes, allowing real‐time observation of the nanowire extrusion process. Additionally, optically transparent

Noise Reduction Techniques for Video Coding Applications [PDF]
, 1998 Granular noise is visually bothersome with respect to high quality rendition, and it is a well known source of visual artifacts for coding algorithms. This work considers the application of nonlinear filtering techniques to granular noise reduction and their effects on video coding.
