Study of axisymmetric underexpanded sonic jets with Mach disks (Density field measurements by rainbow schlieren deflectometry)

The underexpanded sonic jet issued from an axisymmetric convergent nozzle are experimentally investigated in which the nozzle is operated at a pressure ratio of 4.0 to produce a Mach disk in the jet plume.Multidirectional rainbow schlieren pictures of the jet acquired by rotating the nozzle about its longitudinal axis in equal angular intervals are

Driver lines for studying associative learning in Drosophila

The mushroom body (MB) is the center for associative learning in insects.In Drosophila, intersectional split-GAL4 drivers and electron microscopy (EM) connectomes have laid the foundation for precise interrogation of the MB neural circuits.However, investigation of many cell Headphone Lead types upstream and downstream of the MB has been hindered d

Chromosome segregation in plant meiosis

Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles.In plants, defective chromosome segregation caused by gene mutations or other factors leads to the ornament formation of unbalanced or unreduced gametes creating aneuploid or polyploid progeny, respectively.Accurate segregation requires the coordina
