    Notes: Abstract Site-selected insertion (SSI) is a PCR-based technique which uses primers located within the transposon and a target gene for detection of transposon insertions into cloned genes. We screened tomato plants bearing single or multiple copies of maize Ac or Ds transposable elements for somatic insertions at one close-range target and two long-range targets. Eight close-range Ds insertions near the right border of the T-DNA were recovered. Sequence analysis showed a precise junction between the transposon and the target for all insertions. Two insertions in separate plants occurred at the same site, but others appeared dispersed in the region of the right T-DNA border with no target specificity. However, insertions showed a preference for one orientation of the transposon. Use of plants with multiple Ac (HiAc) or Ds (HiDs) elements allowed detection of somatic insertions at two single-copy genes, PG (polygalacturonase) and DFR (dihydroflavonol 4-reductase). Certain HiDs plants showed much higher rates of insertion into PG than others. Insertions in PG and DFR were found throughout the gene regions monitored and, with the exception of one insertion in PG, the junctions between transposon and target were exact. SSI analysis of progeny from the HiDs parents revealed that in some cases the tendency to incur high levels of somatic insertions in PG was inherited. Inheritance of this character is an indication that SSI could be used to direct a search for germinal PG insertions in tomato.

    Description: Author(s): Susanne Still, David A. Sivak, Anthony J. Bell, and Gavin E. Crooks A system responding to a stochastic driving signal can be interpreted as computing, by means of its dynamics, an implicit model of the environmental variables. The system’s state retains information about past environmental fluctuations, and a fraction of this information is predictive of future one... [Phys. Rev.

    Computer based human-centered display system (2002)
    In:  CASI
    Details
    Publication Date: 2019-07-12
    Description: A human centered informational display is disclosed that can be used with vehicles (e.g. aircraft) and in other operational environments where rapid human centered comprehension of an operational environment is required. The informational display integrates all cockpit information into a single display in such a way that the pilot can clearly understand with a glance, his or her spatial orientation, flight performance, engine status and power management issues, radio aids, and the location of other air traffic, runways, weather, and terrain features. With OZ the information is presented as an integrated whole, the pilot instantaneously recognizes flight path deviations, and is instinctively drawn to the corrective maneuvers. Our laboratory studies indicate that OZ transfers to the pilot all of the integrated display information in less than 200 milliseconds. The reacquisition of scan can be accomplished just as quickly. Thus, the time constants for forming a mental model are near instantaneous. The pilot's ability to keep up with rapidly changing and threatening environments is tremendously enhanced. OZ is most easily compatible with aircraft that has flight path information coded electronically. With the correct sensors (which are currently available) OZ can be installed in essentially all current aircraft.
