Abstract

Systems and methods include a computer-implemented method for determining hydrocarbon fuel concentrations. A thin Cyclic Olefin Copolymer (COC) film of a COC layer with a conductive trace that completes an electrical circuit is sputtered. The thin COC film is positioned under tension so that the thin COC film is configured to dissolve upon contact with alkyl aromatic compounds present in hydrocarbon fuels. A sample of a hydrocarbon fuel is positioned on the thin COC film. A determination is made, in response to positioning the sample, that a dissolution of the thin COC film has broken the conductive trace and has rendered the electrical circuit open. A time duration is measured from an introduction of the sample during positioning to an opening of the electrical circuit. A concentration of the hydrocarbon fuel in the sample is determined based on the time duration.

Abstract

A method for diagnosing a disease, such as breast cancer, in a biological sample using spectroscopic data is described. The method involves a computer-implemented method that converts spectroscopic vibrational from the sample into a profile and scores the profile using a pair of reference profiles. Based on the score and a threshold, it can be determined whether the subject from which the sample was obtained has a disease, and, if so, to what extent. The method also allows detection of early and pre-disease states in subjects based on the detection of the signal of low concentration analytes that are indicative of early or incipient disease states. The method is non-invasive, non-subjective, highly specific, and sensitive. The method affords the application of a single standard of diagnostic accuracy, independent of the availability of expert pathologists.

Abstract

Rapid, sensitive, and specific point-of-care testing for pathogens is crucial for disease control. Lateral flow assays (LFAs) have been employed for nucleic acid detection, but they have limited sensitivity and specificity. A fusion of catalytically inactive Cas9 endonuclease and a relaxase for example, VirD2 are used for sensitive, specific nucleic acid detection by LFA. VirD2-dCas9 specifically binds the target nucleic acid sequence via dCas9 and covalently binds to a FAM-tagged oligonucleotide via VirD2. The biotin label and FAM tag are detected using a LFA. This system, termed Vigilant (VirD2-dCas9 guided and LFA-coupled nucleic acid test) is coupled to reverse transcription-recombinase polymerase amplification to detect pathogenic nucleic acid of interest in a sample, it exhibits an impressive limit of detection and shows no cross-reactivity, thus reducing incidents of false positives. Vigilant offers an easy-to-use, rapid, cost-effective, and robust detection platform for SARS-CoV2.

Abstract

An air breathing filtering system includes a housing having an air input and an air output, a first filtering stage that filters out particles from a first air stream to generate a second air stream, and a second filtering stage that filters out germs from the second air stream to generate a third air stream, wherein the second filtering stage uses a different filtering process than the first filtering stage. The first air stream is received at the air input and the third air stream is discharged outside the housing at the air output. The second filtering stage uses a liquid to disable the germs from the second air stream.

Abstract

Systems and methods for identifying an oil spill in a body of water include obtaining an image of the body of water from a multispectral satellite for a first time period and a second time period. One or more features are extracted the from the image to form a first feature vector for the first time period and a second feature vector for the second time period with the one or more features representing a physical feature of a surface of the body of water. The feature vectors are processed using a machine learning model trained with labeled image data representing instances of oil on the surface of the body of water to determine the type and location of oil in the body of water.

Abstract

Systems and methods for quantifying and remediating an oil spill in a body of water can include obtaining a synthetic aperture radar image of the body of water and/or a multispectral image of the body of water. One or more features representing a physical feature of a surface of the body of water can be extracted from the image(s). The extracted features can be processed using a machine learning model trained with labeled image data representing instances of oil on the surface of the body of water to associate oil appearances code with portions of the surface of the water body based on the extracted features. Based on the processing, areas of the body of water associated with each oil appearance code as well as locations and volumes of oil in the body of water can be determined.

Abstract

Systems and methods for tracking and remediating oil in a body of water include monitoring the data from the satellite for indications of an oil spill. In response to determining that the indications of oil spill are present, assessing whether criteria for triggering a forecasting process are met. In response to determining that criteria for triggering a forecasting process have been met, running a forecasting process including: (i) delineating polygons where oil is determined to be present based on the data from the satellite; (ii) receiving meteorological and hydrodynamic data for the body of water; (iii) running a trajectory model using the polygons as initial conditions for the oil spill to forecast future locations of the oil spill; and sending instructions to a vessel in the body of water.
