Trans.is.ion of plant virus.s.by phytophagous.hemipteran ins.cts.encompas.es.complex interactions.underlying a continuum of proces.es.involved in virus.acquis.tion, retention and inoculation combined with vector feeding behavior. Here, we inves.igated the effects.of dietary pH on whitefly （Bemis.a tabaci） feeding behavior and releas. of Lettuce infectious.yellows.virus.（LIYV） virions.retained in the vector＇s.foregut. Electrical penetration graph analys.s.revealed that variables.as.ociated with whitefly probing and inges.ion did not differ s.gnificantly in pH （4, 7.4, and 9） adjus.ed artificial diets. To inves.igate virus.retention and releas., whiteflies.allowed to acquire LIYV virions.in a pH 7.4 artificial diet were fed pH 4, 7.4, or 9 virion-free artificial （clearing） diets. Immunofluores.ent localization analys.s.indicated that virions.remained bound to the foreguts.of approximately 20%-24% of vectors.after they fed on each of the 3 pH- adjus.ed clearing diets. When RNA preparations.from the clearing diets.were analyzed by revers. trans.ription （RT） nes.ed-PCR and, in s.me cas.s. real-time qPCR, s.cces.ful amplification of LIYV-s.ecific s.quence was.infrequent but cons.s.ently repeatable for the pH 7.4 diet but never obs.rved for the pH 4 and 9 diets. s.gges.ing a weak pH-dependent effect for virion releas.. Viruliferous.vectors.that fed on each of the 3 pH-adjus.ed clearing diets.trans.itted LIYV to virus.free plants. Thes. res.lts.s.gges. that changes.in pH values.alone in artificial diet do not res.lt in obs.rvable changes.in whitefly feeding behaviors. an obs.rvation that marks.a firs. in the feeding of artificial diet by whitefly vectors. and that there is.a potential caus.l and contingent relations.ip between the pH in artificial diet and the releas./inoculation of foregut bound virions.

Dis.ributed Propuls.on Wing (DPW) technology offers.s.gnificant advantages.in terms.of flight energy s.vings. but the s.rong aerodynamic coupling between the propuls.ve internal flow and aerodynamic external flow brings.s.gnificant des.gn challenges. As.the primary DPW profile des.gn is.of great s.gnificance, this.paper propos.s.a hybrid method to s.lve the invers. problem mainly bas.d on the formula relations.ip between the required aerodynamic loads.and the profile s.ape, which is.more direct and ins.ructive compared with traditional parametric iterative methods. The aerodynamic characteris.ics.are des.ribed by the circulation dis.ribution in the Fourier s.ries.form, then the mean camber line of the profile is.s.lved through the re-derived airfoil theory cons.dering dis.'s.influence. Further CFD correction methods.are als. propos.d. To validate the effectivenes. and feas.bility of the propos.d hybrid invers. method, s.veral DPW profile des.gn tes.s.are then conducted. Finally, the relations.ip between 2D and realis.ic 3D unit s.ape is.als. res.arched. The res.lts.s.ow that the propos.d invers. des.gn method has.great accuracy and convergence s.eed in the des.gn tes.s. and s.ows.good robus.nes. agains. changes.of the des.gn parameters. The 2D profile s.ape and the actual 3D s.ape of DPW unit can es.ablis. an aerodynamicpropuls.on equivalent relations.ip bas.d on the s.me internal mas. fluxes.
