Using physiological assays coupled with ultrathin tissue sections, we investigated the impacts of exogenous selenium (Se) on the growth, antioxidant enzymes, osmotic regulation and ultrastructural modifications of leaf mesophyll and root tip cells of 100 mM NaCl-stressed sorrel (Rumex patientia × R. tianshanicus) seedlings. At low concentrations (1–5 μM),(More)
To investigate the roles of protein phosphatases 1 and 2A in the development of pollen tubes of Picea wilsonii Mast., pollen grains were cultured in standard medium in the presence and absence of the protein phosphatase inhibitors okadaic acid and calyculin A. At nanomolar concentrations, these compounds blocked pollen tube growth, causing abnormal(More)
We report a mechanism to obtain optical pulling or pushing forces exerted on the active dispersive chiral media. Electromagnetic wave equations for the pure chiral media using constitutive relations containing dispersive Drude models are numerically solved by means of Auxiliary Differential Equation Finite Difference Time Domain (ADE-FDTD) method. This(More)
Coronary flow (CF) measured ex vivo is largely determined by capillary density that reflects angiogenic vessel formation in the heart in vivo. Here we exploit this relationship and show that CF in the rat is influenced by a locus on rat chromosome 2 that is also associated with cardiac capillary density. Mitochondrial tryptophanyl-tRNA synthetase (Wars2),(More)
In order to pull objects towards the light source a single tractor beam inevitably needs to be strongly nonparaxial. This stringent requirement makes such a tractor beam somewhat hypothetical. Here we reveal that the cylindrical shape of dielectric particles can effectively mitigate the nonparaxiality requirements, reducing the incidence angle of the(More)
This paper firstly introduces elementary knowledge of bio-electromagnetic dose, and then elaborates on the method and steps of theoretical bio-electromagnetic dose used to compute the electromagnetic dose absorbed by human body at the frequency 300MHz and 3GHz. Afterwards, the finite-difference time-domain (FDTD) method is utilized to analyze the dielectric(More)
Polar Mesosphere Summer Echoes (PMSE) are strong radar echoes that have been observed typically by the VHF radar in summer polar mesosphere and have closely relation with charged dust particles. Theoretical analysis and extensive experimental data show that polar mesosphere summer echoes (PMSE) present some kind of regular periodic changes, such as(More)
Polar summer mesopause region belong to dusty plasma, the impact of dusty plasma on the electromagnetic signals have been verified by lots of experiments. If the system of space microwave energy transmission will be used in high latitudes of both hemispheres in the future, we need to pay more attention on dusty plasma in polar mesosphere. In the paper we(More)
