The flight muscles, dorsal air sacs, wing blades, and thoracic cuticle of the Drosophila adult function in concert, and their progenitor cells develop together in the wing imaginal disc. The wing disc orchestrates dorsal air sac development by producing decapentaplegic and fibroblast growth factor that travel via specific cytonemes in order to signal to the air sac primordium (ASP). Here, we re...

The Drosophila wing primordium is subdivided into adjacent territories called compartments (García-Bellido et al., 1973). Anteroposterior (AP) and dorsoventral (DV) compartment subdivisions are primarily established by the activity of the selector genes engrailed in P cells and apterous in D cells (reviewed by Blair, 1995). Short-range interactions between adjacent compartments induce expressio...

The rise of wing-rock motion in delta-wing aircraft has an adverse effect on the manoeuvrability and it may result its crash. This study presents a finite-time control design to tackle dynamic due Wing-Rock aircraft. is developed based methodology Super Twisting Sliding Mode Control (STSMC). Lyapunov stability analysis been pursued ensure asymptotic convergence errors determine finite time. STS...

The use of pheromone trap catches to reliably predict damage by the Nantucket pine tipmoth,Rhyacionia frustrana (Comstock), in loblolly pine (Pinus taedaL.)plantationswouldprovide forest managers with a valuable integrated pest management tool. At 17 sites throughout four states in the southern United States, in areas where R. frustrana has four annual generations, adult moths were monitored th...

Delta and Notch are required for partitioning of vein and intervein cell fates within the provein during Drosophila metamorphosis. We find that partitioning of these fates is dependent on Delta-mediated signalling from 22 to 30 hours after puparium formation at 25 degrees C. Within the provein, Delta is expressed more highly in central provein cells (presumptive vein cells) and Notch is express...
