Effects of Bacillus subtilis F-1 and F-2 on inhibiting the growth of Fusarium oxysporum f. sp. cucumerinum (F. o. c) were studied by a co-culture experiment. The results showed that the growth of F. o. c could be strongly inhibited by the specific metabolites of Bacillus subtilis F-2, but not by Bac...

A bacterial strain BD-24, which was able to use decabromodiphenyl ether (BDE-209) as the sole carbon and energy source, was isolated from activated sludge in an oil refinery at Hangzhou, China by selective enrichment method. Based on morphological, physiological and biochemical characteristics, phyl...

Virus-like particles (VLPs) are hollow nanoparticles composed of one or several virus structural proteins, which have a morphological structure similar to natural viruses but do not contain any genetic material. Due to the excellent innate immunogenicity and safety of VLPs, they are often used in th...

The effects of epibrassinolide on ultrastructure of epidermous cell in hypocotyl segments of mung bean seedlings were studied. Hypocotyl segments treated with epibrassinolide (1 mg/L) maintained the integrity of ultrastructure of cell, and retarded the senescence, whereas the various organelles of t...

The embryonic cerebral cells (ECC) of pregnant SD rats (17-19 days) were cryopreserved by vitrification. After cryopreservation for 3,10,20,30 and 60 days, the individual ECC samples were separately thawed in 38℃ water bath or by microwave treatment in 300 mL 10℃ water under microwave power of 800W,...

Here, we research a novel cavity magnomechanical system, where the magnon mode with Kerr nonlinearity driven by a microwave field couples to a phonon mode with a magneostrictive nonlinear interaction (radiation pressure-like). Based on these nonlinear properties, we numerically demonstrate magnon ch...

Recent studies using the Gaia DR3 data have revealed a two-armed phase spiral in the Z – V _Z phase space in the inner disk. In this study, we present new features of the two-armed phase spiral revealed by the Gaia data and a new mechanism to explain such features with multiple external perturbation...

Microwave nonreciprocity is in high demand for applications in information processing. Here, we propose an effective approach to realize robust microwave transmission nonreciprocity in a three-mode non-Hermitian cavity magnetic system (CMS). We show that, around the exceptional point, robust microwa...
