Graphene Biosensors for Early Ketosis Detection in Cows
THE CHALLENGE The challenge facing dairy producers today is the lack of a reliable, affordable, and easy-to-use solution for early detection of subclinical ketosis in cows during early lactation, a period when animals are especially vulnerable due to negative energy balance. Elevated levels of beta-hydroxybutyrate or BHB in blood and milk are key...

Highly Sensitive 3D Sensors for Prevention of Hypocalcemia in Dairy Cows
THE CHALLENGE Hypocalcemia, colloquially known as Milk Fever, is a common metabolic disorder caused by severe calcium deficiency most prevalent in dairy cows. This disorder has clinical and subclinical levels of severity, the latter often going undetected due to lack of symptoms. Without treatment, up to 60-80% of cases result in death. Further, milk...

PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids
The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers
Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

All-Fiber Multicore Fiber Laser Devices
Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
