    Abstract: A reacting canister utilizing transparent optical fiber technology coated with a photo-catalyst and a plasmonic layer, including yttrium aluminum garnet nanoparticles, disposed between the optical fiber and the photo-catalyst to degrade off-flavor compounds in aquacultured aquatic life. The degradation of off-flavored compounds—including 2-methylisoborneol—can be significantly enhanced by increasing the surface area of the catalyst. Coating individual transparent optical fibers and aligning those fibers in a canister configuration allows the treatment of large volumes of water in portable and scalable reactors. Once the fluid is treated, the fluid is returned to the reservoir containing the aquacultured aquatic life.

    Abstract: An in vitro microfluidic device includes a device configured to model a blood-brain barrier. The device includes a center well in fluidic communication with each of an inlet and an outlet. Each of the center well, inlet, and outlet includes a porous membrane that separates a “blood” portion (a fluid flow portion) from a “brain” portion (a fluid containing portion). The porous membrane is seeded with endothelial cells such as the human venule endothelial cells (HUVECs) on the blood side, and with astrocytes on the brain side, to accurately model the blood-brain barrier. Fluid flows between the inlet, the center well, and the outlet to test the permeability of the porous membrane, thereby providing an accurate in vitro model of a blood-brain barrier.

    Abstract: A mobile phone-based system for ELISA (MELISA). The MELISA system can perform all steps of ELISA procedure and output hormone concentration values. The system includes a heater that keeps the temperature required for sample incubation, illumination system for sample image capturing, and a digital camera system. All components are enclosed in a dark box to create optimal light conditions for image capturing. After sample images are captured, they are digitally processed, and hormone concentration values are reported based on colorimetric data from the samples. The system can be used to complete all steps of the assay, including incubation and reading. It is lightweight, can be fabricated at low cost, is portable, and can transfer test results via mobile phone. MELISA can be calibrated for accurate measurements of progesterone and has demonstrated successful measurements with the calibrated system.

    Abstract: A new system and method for FWI of common-offset GPR data, particularly targeting the dimensions and infilling material of buried objects. The method is useful in situations where clear isolated diffraction hyperbolas indicate the presence of an underground object, but the object's dimensions and filling may be unknown. The present invention acquires GPR data and applies advanced numerical methods to get the depth and size of the underground object in a very accurate manner. An embodiment of the invention includes five main steps: GPR data processing, ray-based analysis to set a good initial model, 3D to 2D transformation of data, effective SW estimation, and FWI.
