Abstract: The present invention relates to methods of testing medications to evaluate authenticity and identify counterfeits. The testing methods employ a reactive system comprising a solvent and an acid. Optionally, the reactive system can also comprise an organometallic agent. The testing methods can provide rapid results verifying the authenticity of an antimalarial medication. Further the test method can provide clear results that can be implemented and interpreted without special training, anywhere in the world. The test methods can offer quantitative and qualitative results. The test methods are based on reactions that yield different colors where the color can indicate the presence of an active ingredient, and the intensity of the color can indicate the concentration of the active ingredient.

Abstract: An apparatus with either a graphene sheet or an epsilon-near-zero layer sandwiched in a waveguide structure and a tuning device. The tuning device is configured to selectively control application of at least first and second gate voltages across the waveguide structure. The graphene sheet has a first dielectric constant which is zero and the waveguide structure operates at a first absorption state and a first propagation distance with application of the first voltage by the tuning device and has a second dielectric constant and the waveguide structure operates at a second absorption state and a second propagation distance with application of the second voltage. The second dielectric constant is larger than the first dielectric constant, the second absorption state is smaller than the first absorption state, the second propagation distance is longer than the first propagation distance, and the second voltage which is zero or smaller than the first voltage.

Abstract: A method for modifying the refractive index of an optical, hydrogel polymeric material. The method comprises irradiating predetermined regions of an optical, polymeric material with a laser to form refractive structures. To facilitate the formation of the refractive structures the optical, hydrogel polymeric material comprises a photosensitizer. The presence of the photosensitizer permits one to set a scan rate to a value that is at least fifty times greater than a scan rate without the photosensitizer in the material, yet provides similar refractive structures in terms of the observed change in refractive index. Alternatively, the photosensitizer in the polymeric material permits one to set an average laser power to a value that is at least two times less than an average laser power without the photosensitizer in the material, yet provide similar refractive structures. The method can be used to form refractive structures in corneal inlays and intraocular lenses following the insertion of such optical devices in an eye of a patient.

Abstract: An example of an apparatus including a communication interface to receive an image file is provided. The image file represents a scanned image of a output generated by a printing device. The apparatus further includes an identification engine to process the image file with a convolutional neural network model to identify a feature. The feature may be indicative of a potential failure. The apparatus also includes an image analysis engine to indicate a life expectancy of a part associated with the potential failure based on the feature. The image analysis engine uses the convolutional neural network model to determine life expectancy.
