N- and p-type regions have been produced in GaN using Si+ Mg+/P+ implantation, respectively, subsequent annealing at ∼1100 °C. Carrier activation percentages of 93% for Si 62% Mg were obtained implant doses 5×1014 cm−2 each element. Conversely, highly resistive (≳5×109 Ω/⧠) can be initially n- or p- type by N+ implantation ∼750 The energy the deep states controlling resistivity these implant-isolated materials is range 0.8–0.9 eV. These process modules are applicable to fabrication a variety...
Melanization, an important insect defense mechanism, is mediated by clip-domain serine protease (cSP) cascades and regulated serpins. Here we show that proteolytic activation of prophenoloxidase (PPO) PO-catalyzed melanization kill the baculovirus in vitro. Our quantitative proteomics biochemical experiments revealed infection cotton bollworm, Helicoverpa armigera, reduced levels most cascade members host hemolymph PO activity. By contrast, serpin-9 serpin-5 were sequentially upregulated...
W was found to produce low specific contact resistance (ρc∼8.0×10−5 Ω cm2) ohmic contacts n+-GaN (n=1.5×1019 cm−3) with limited reaction between the metal and semiconductor up 1000 °C. The formation of β–W2N W–N interfacial phases were deemed responsible for electrical integrity observed at these annealing temperatures. No Ga out-diffusion on surface thin (500 Å) even after °C, 1 min anneals. Thus, appears be a stable high temperature applications.
Abstract Background Ticks serve as vectors for a diverse array of pathogens, including viruses responsible both human and livestock diseases. Symbiotic bacteria hold significant potential controlling tick-borne disease. However, the alteration tick gut bacterial community in response to pathogen infection has not been analyzed any viruses. Here, impact severe fever with thrombocytopenia syndrome virus (SFTSV) on diversity Haemaphysalis longicornis is investigated. Methods Unfed females were...
Skin immunity protects animals from airborne pathogen infection. Unlike mammals, arthropods, including insects, undergo periodic ecdysis to grow and develop. Newly-molted insects emerge with un-sclerotized thin cuticles but successfully escape pathogenic infections during the post-molt period. Here we show that prophenoloxidases in molting fluids remain bioactive on integument impede fungal infection after ecdysis. We found purified plasma or recombinant could effectively bind spores...
Over the past decades, Helicoverpa armigera nucleopolyhedrovirus (HearNPV) has been widely used for biocontrol of cotton bollworm, which is one most destructive pest insects in agriculture worldwide. However, molecular mechanism underlying interaction between HearNPV and host remains poorly understood. In this study, high-throughput RNA-sequencing was integrated with label-free quantitative proteomics analysis to examine dynamics gene expression fat body H. larvae response challenge HearNPV....
Melanization is a prominent insect humoral response for encapsulation of and killing invading pathogens. It mediated by protease cascade composed modular serine (SP), clip domain SPs (cSPs), which converts prophenoloxidase (PPO) into active phenoloxidase (PO). To date, melanization pathway in cotton bollworm Helicoverpa armigera, an important agricultural pest, remains largely unclear. biochemically reconstitute the vitro, putative proteases along with modified containing factor Xa cleavage...
Baculoviruses are natural enemies of agricultural and forest insect pests play an important role in biological pest control. Oral infection by baculovirus the midgut is necessary for establishing systemic eventually killing insect. Since continuously encounters microbiota, gut microbiota could affect infection. Here, we demonstrated that modulates immune responses promotes cotton bollworm, Helicoverpa armigera. After oral infection, numerous host immunity-related genes including encoding...
Severe fever with thrombocytopenia syndrome (SFTS) caused by the SFTS virus (SFTSV) is an emerging tick-borne disease a high mortality rate. Haemaphysalis longicornis primary reservoir and vector of SFTSV. Here, we found that targeting subolesin (SUB), anti-tick vaccine candidate, affects infection transmission SFTSV in H. longicornis. RNAi-mediated knockdown SUB repressed salivary glands but not gut longicornis, which may be associated modulation protein processing endoplasmic reticulum...
With global climate warming and the alteration of precipitation regime, Three-North Shelter Forest in China has been degraded recent years, which is a primary challenge for shelterbelt construction. Our understan-ding physiological mechanisms behind forest decline remains limited. In this study, we employed dendrochronological methods to measure basal area increment (BAI) tree-ring width both healthy Pinus sylvestris var. mongolica Populus L. We developed corresponding standardized...
Abstract We report a molecular modelling study to validate the forcefields [condensed-phase optimised potentials for atomistic simulation studies (COMPASS) and polymer-consistent forcefield (PCFF)] in predicting physical thermophysical properties of polymers. This work comprises two key steps: (1) generating validating model material bulk amorphous emeraldine base polyaniline (2) glass–rubber transition polymer. From all dynamics results, it clearly shows that more recent COMPASS provides...
