Nanoimprinted Collagen Plasmonic Sensors
Small Structures, Volume 6, Issue 12, December 2025.A process to create collagen 3D nanostructures has been developed based on thermal nanoimprinting using mild conditions. This versatile process is suitable for transferring collagen patterns to both soft and rigid substrates, allowing for applications in various fields, including biomedicine and bio‐organic electronics.

Nitrergic Signaling Mediation of Neurobehavioral Responses to Stress in Zebrafish
Journal of Neurochemistry, Volume 169, Issue 10, October 2025.Nitric oxide (NO) production is regulated by a plethora of upstream mediators, including glutamate, serotonin, and inflammatory mediators, at both neurons and non‐neuronal cells. These mediators are regulated by stressors, and their activity can increase or decrease NO production in a nitric oxide synthase (NOS) isoform‐dependent way.

Journal of Control Science and Engineering, Volume 2012, Issue 1, 2012., 2012 One of the main advantages of predictive control approaches is the capability of dealing explicitly with constraints on the manipulated and output variables. However, if the predictive control formulation does not consider model uncertainties, then the constraint satisfaction may be compromised.

Journal of Electrical and Computer Engineering, Volume 2012, Issue 1, 2012., 2012 An enhanced genetic algorithm (EGA) is applied to solve the long‐term transmission expansion planning (LTTEP) problem. The following characteristics of the proposed EGA to solve the static and multistage LTTEP problem are presented, (1) generation of an initial population using fast, efficient heuristic algorithms, (2) better implementation of the ...
