A position of the detected target vegetation is determined within the one or more images. An applicator disposed on an agrochemical applicator system that is mapped to the position of the detected target vegetation within the one or more images is determined. The applicator is activated based on a current speed of a vehicle coupled to the agrochemical applicator system, and further based on configuration data associated with the applicator. Activating the applicator selectively applies an agrochemical to the detected target vegetation.

Abstract: The subject invention pertains to a Molecular Cell Diary System (MCDS), which allows identification of the history of somatic alterations in the cell. MCDS comprises one or more combinations of a DNA cutter and a DNA writer expressed under the control of a promoter controlled a cellular event of interest. The DNA cutter and the DNA writer are in a combination are co-expressed when an even of interest occurs. The DNA cutter creates double strand breaks (DSB) in a target DNA in a sequence specific manner and the DNA writer incorporates DNA sequences in the DSB. The endogenous DNA repair machinery synthesizes repairs the DSB. As such, the combination of the DNA cutter and the DNA writer modifies the target DNA and leaves “marks” of the occurrence of the cellular event of interest. These marks are sequenced and the cellular event history of the cell is deciphered.

Abstract: A treatment efficacy of a treatment for treating a parkinsonian disease is determined. A first set of imaging information/data associated with a dMRI scan of an individual's brain captured at a first time and a second set of imaging information/data associated with a dMRI scan of the individual's brain captured at a second time are received. The individual underwent the treatment for a time period comprising at least part of the time between the first and second times. An expected change between the first and second times is determined based on a natural progression of the parkinsonian disease. The first and second sets of imaging information/data are analyzed to determine a first free-water pattern and a second free-water pattern. Based on the first and second free-water patterns, a disease progression score is determined. Based on the disease progression score and the expected change, a treatment efficacy for treating the individual with the treatment is determined.
