A Hybrid Model of Limited Burst Retransmission and Deflection Routing in Optical Switching Network

Cybernetics and Information Technologies
Optical Burst Switching (OBS) is considered a promising optical switching technology for the future. However, a key issue of the OBS network is reducing dropped bursts due to contentions because there is no optical buffer at intermediate nodes.

Adsorption and Separation by Flexible MOFs

Advanced Materials, EarlyView.
Flexible metal–organic frameworks (MOFs) present significant potential for gas storage and separation due to their structural dynamic. This review explores the rationale behind the flexible MOFs' enhanced working capacity and separation factors. It also addresses key challenges, including phase transition kinetics, crystal robustness, cycling, shaping,

Super pulses of orbital angular momentum in fractional-order spiroid vortex-beams [PDF]

, 2017
We consider optical properties of Hypergeometric-Gaussian beam compositions with spiral-like intensity and phase distributions that were called the spiroid beams. Their orbital angular momentum as a function of a fractional-order topological charge has a chain of supper-pulses (bursts and dips).The form of the supper-pulses can be controlled by the ...
