Autonomous and Communicative Microcapsule Systems for Life‐Like Homeostatic pH Regulation

open access: yesSmall, EarlyView.
A dual‐microcapsule system mimicking biological homeostasis is developed, enabling programmable pH oscillations through antagonistic enzymatic feedback. Monodisperse urease and esterase capsules, produced via hybrid‐junction 3D‐printed microfluidics with epoxy‐modified channels, exhibit adaptive shell permeability and inter‐capsule communication.

Depth from optical turbulence

2012 IEEE Conference on Computer Vision and Pattern Recognition, 2012
Turbulence near hot surfaces such as desert terrains and roads during the summer, causes shimmering, distortion and blurring in images. While recent works have focused on image restoration, this paper explores what information about the scene can be extracted from the distortion caused by turbulence.

Controlling optical turbulence

Physical Review A, 1997
A robust global control strategy, implemented as a spatial filter with delayed feedback, is shown to stabilize and steer the weakly turbulent output of a spatially extended system. The latter is described by a generalized complex Swift-Hohenberg equation [J. Lega, J. V. Moloney, and A. C. Newell, Phys. Rev. Lett.
