Abstract: Methods, systems, and computer readable media for performing FDG positron emission tomography (PET) quantification, segmentation, and classification of abnormalities are disclosed. One method includes receiving a plurality of magnetic resonance (MR) images corresponding to a target site of a subject and generating three dimensional (3D) area masks of abnormality volumes from the plurality of MR images. The method further includes segmenting the 3D area masks into one or more individual seed images for each of the abnormality volumes and overlaying the one or more individual seed images onto co-registered parametric PET maps to generate kinetic rate parameters for each of the abnormality volumes. The method also includes utilizing the kinetic rate parameters to train a logistic regression engine to predict a target site condition assessment based on a classification of the abnormality volumes.

Abstract: A controller for an indoor grow lighting system is provided and can include a digital communication module and an analog communication module that are each configured to communicate with a plurality of light fixtures. The controller also includes a controller area network communication module that facilitates communication with a plurality of sensors. The controller is configured to conduct different testing procedures on the light fixtures.

Abstract: A VPD sensor for a horticultural environment is provided. The VPD sensor includes an upper housing, a lower housing, and a vapor pressure deficit sensing module. The lower housing is coupled with the upper housing and includes a lower sidewall and a bottom wall that cooperate to define an interior. The vapor pressure deficit sensing module is coupled with the lower housing and is disposed in the interior. The upper housing and the lower housing are spaced from each other along a centerline to define an air gap therebetween that is in fluid communication with the interior. The lower sidewall defines an opening that is in fluid communication with the interior and cooperates with the interior and the air gap to define a fluid pathway that extends through the interior and between the opening and the air gap.

Abstract: A soil sensor for a horticultural environment is provided. The soil sensor includes at least one probe, a sensing module, and an onboard controller. The at least one probe is configured for insertion into a soil substrate. The sensing module is associated with the at least one probe and is configured to detect an environmental parameter of the soil substrate via the at least one probe. The onboard controller is in signal communication with the sensing module and is configured to determine a value of the environmental parameter from the measured environmental parameter.

Abstract: A continuous dynamic positron emission tomography (PET) assembly for imaging a target region of a subject. The assembly includes a radioactive tracer isotope injector configured to administer a radioactive isotope into the subject and a scintillator crystal configured to absorb ionizing radiation from the subject and emit scintillator light. The scintillator crystal undertakes the absorption substantially at the same time of the start of administering the radioactive isotope. The assembly also includes a photo detector in communication with the scintillator crystal, wherein the photodetector is configured to detect the emitted scintillation light as input and provide electrical signals as output. The assembly further includes a signal digitizing circuitry converting the output electrical signals into digital data. Moreover, the assembly includes a processor configured to receive the digital data and implement a model to convert the digital data into a three dimensional, tomographic image reconstruction.

Abstract: The gesture-based input device for a user interface of a computer comprises two pairs of electrodes scalable for any screen size wherein the electrodes are arranged to capture the quasi-electrostatic field surrounding the user in order for the graphic user interface to provide different options or tasks to be selected by a user, a platform for supporting a user, a quasi-electrostatic field generator source connected to the platform and a circuitry connected to the electrodes for determining, relative to each of the electrodes, the position of that part of a user supported by the platform, e.g. a user's hand, being closest to the electrodes.
