Retrieval optical solitons of perturbed Radhakrishnan-Kundu-Lakshmanan equation
No full textIn this paper, the soliton behavior of the (2+1)-dimensional perturbed Radhakrishnan-Kundu-Lakshmanan equation utilizing by the new Kudryashov method is investigated. First of all, the nonlinear ordinary differential equation form of the perturbed Radhakrishnan-Kundu-Lakshmanan equation has been obtained by inserting the complex wave transformation into nonlinear partial differential equation form of the perturbed Radhakrishnan-Kundu-Lakshmanan equation. The algorithm of the proposed method has been expressed and applied to the obtained nonlinear ordinary differential equation. Then, a polynomial expression has been achieved and converted to linear algebraic system. After solving and selecting the appropriate solution set, different soliton solutions of the investigated perturbed Radhakrishnan-Kundu-Lakshmanan equation has been derived. Finally, 3D and 2D graphics of some solutions are depicted for chosen suitable parameters.</p

Ultrastructure of male reproductive accessory glands and ejaculatory duct in the Queensland fruit fly, Bactrocera tryoni (Diptera: Tephritidae)
No full textUltrastructure of male reproductive accessory glands and ejaculatory duct in the Queensland fruit fly (Q-fly), Bactrocera tryoni, were investigated and compared with those of other tephritid flies. Male accessory glands were found to comprise one pair of mesodermic glands and three pairs of ectodermic glands. The mesodermic accessory glands consist of muscle-lined, binucleate epithelial cells, which are highly microvillated and extrude electron-dense secretions by means of macroapocrine transport into a central lumen. The ectodermic accessory glands consist of muscle-lined epithelial cells which have wide subcuticular cavities, lined with microvilli. The electron-transparent secretions from these glands are first extruded into the cavities and then forced out through small pores of the cuticle into the gland lumen. Secretions from the two types of accessory glands then flow into the ejaculatory duct, which is highly muscular, with epithelial cells rich in rough endoplasmic reticulum and lined with a thick, deeply invaginated cuticle. While there are some notable differences, reproductive accessory glands of male Q-flies generally resemble those of the olive fruitfly, Bactrocera oleae, and to a lesser extent the Mediterranean fruit fly, Ceratitis capitata

P-type poly-Si/SiOx contact by aluminium-induced crystallization of amorphous silicon
No full textIn this work, we explored aluminium-induced crystallization (AIC) of amorphous Si (a-Si) as a low-temperature alternative to make p-type poly-Si/SiOx contacts for Si solar cells. In this approach, a stack of Al and a-Si deposited on a SiOx-passivated Si wafer surface is annealed at temperatures below 577 degrees C (the eutectic temperature of Al-Si mixture), which induces the exchange of Al and Si layer positions in the stack and the simultaneous crystallization of a-Si to Al-doped p-type poly-Si, potentially leading to the formation of an Al/polySi/SiOx passivating contact. The Al-doped AIC poly-Si has low carrier concentration, and thus to compensate for this, we used highly B-doped a-Si for AIC and could achieve a tenfold increase in the carrier concentration. We found that the typical thickness of 1.5 nm of the passivating SiOx layer is too low for this AIC-based approach, as Al reduces SiOx during the process and degrades its passivation quality. By starting with a thicker SiOx layer, we could demonstrate that AIC poly-Si/SiOx contacts with low contact recombination is achievable. However, the contact characteristic remains non-ohmic. This can be improved by extended annealing after AIC, during which Al diffuses into the Si substrate. The Al diffusion, however, damages the SiOx layer and in turn severely increases contact recombination. We conclude that with AIC poly-Si/SiOx contacts the process window to achieve low contact resistivity and low contact recombination seems to be very narrow, if existing at all.The authors gratefully acknowledge the funding from the Kuwait Foundation for the Advancement of Sciences (KFAS) under the project number CN18-15EE-01.
