Demonstration of sustained and useful converter responses during balanced and unbalanced faults in microgrids [PDF]

open access: yes, 2012
In large power grids where converter penetration is presently low and the network impedance is predominantly reactive, the required response from converters during faults is presently specified by phrases such as “maximum reactive output”.

Management strategy evaluation for salmon habitat restoration and hatchery supplementation

open access: yesConservation Science and Practice, EarlyView.
Building on three previously published studies, this paper applies population modeling work to evaluate the effects of different habitat and hatchery management strategies on achieving recovery goals for endangered Chinook salmon. We find that it would require a >150% improvement in juvenile survival to achieve recovery goals for population abundance ...

Multilayer Soft Photonic Arrays Inspired by Cephalopod Skin for High‐Density, Independent, and Multimodal Actuation

open access: yesAdvanced Functional Materials, Volume 36, Issue 31, 16 April 2026.
A vertically stacked, DEA‐driven photonic array inspired by cephalopod skin, featuring highly crystalline colloidal crystal gels with vivid color, low FWHM and scalability is presented. The multilayer design removes lateral pixel interference, achieving near‐100% fill factor with fully independent RGB actuation.
