Simultaneous Determination of Four Ingredients in Plantago Depressa by Single Marker

Objective. To establish a quantitative analysis of multicomponents by single marker (QAMS) method for the simultaneous determination of 4 active components such as protocatechuic acid, catechin, quercetin, and luteolin in Plantago depressa. Method. 4 active components in Plantago depressa were studied. Quercetin was used as an internal reference to establish the relative correction factors among protocatechuic acid, catechin, and luteolin and calculate the contents of each component; the results were compared with those measured by the external standard method. Results. 4 components showed a good linear relationship in their respective concentration ranges (r > 0.9995). The relative correction factors (fs/k) of protocatechuic acid, catechin, and luteolin were 1.1992, 0.8613, and 1.6069, respectively. The method had good durability. The contents of protocatechuic acid, catechin, and luteolin calculated by QAMS were not significantly different from those measured by the external standard method. Conclusion. QAMS can be used to determine the content of 4 components in Plantago depressa at the same time, and the method is simple, accurate, and can be used for quality control.

The QCD corrections of the process h → ηbZ

We investigate the 125 GeV Higgs boson decay to a pseudoscalar quarkonium [Formula: see text] and [Formula: see text] boson. We calculate the quantum chromodynamics (QCD) one-loop corrections to the branching ratio of the process, [Formula: see text], both in the Standard Model (SM) and in the two Higgs double models (THDM). Adding the QCD one-loop corrections, the branching ratio of [Formula: see text] in the SM is [Formula: see text]. The relative correction of that QCD one-loop level relative to the tree level of [Formula: see text] is around 76% in the SM. Similarly, the relative correction in the THDM also can be around 75%. The key parameter, [Formula: see text], can affect the relative correction in the THDM.

RADIOMETRIC CORRECTION OF MULTITEMPORAL HYPERSPECTRAL UAS IMAGE MOSAICS OF SEEDLING STANDS

Novel miniaturized multi- and hyperspectral imaging sensors on board of unmanned aerial vehicles have recently shown great potential in various environmental monitoring and measuring tasks such as precision agriculture and forest management. These systems can be used to collect dense 3D point clouds and spectral information over small areas such as single forest stands or sample plots. Accurate radiometric processing and atmospheric correction is required when data sets from different dates and sensors, collected in varying illumination conditions, are combined. Performance of novel radiometric block adjustment method, developed at Finnish Geospatial Research Institute, is evaluated with multitemporal hyperspectral data set of seedling stands collected during spring and summer 2016. Illumination conditions during campaigns varied from bright to overcast. We use two different methods to produce homogenous image mosaics and hyperspectral point clouds: image-wise relative correction and image-wise relative correction with BRDF. Radiometric datasets are converted to reflectance using reference panels and changes in reflectance spectra is analysed. Tested methods improved image mosaic homogeneity by 5 % to 25 %. Results show that the evaluated method can produce consistent reflectance mosaics and reflectance spectra shape between different areas and dates.

PRODUCTION OF $ht\bar{t}$ AND $ht\bar{T}$ IN THE LEFT–RIGHT TWIN HIGGS MODEL IN γγ COLLISIONS AT ILC

In the left–right twin Higgs (LRTH) model, we first examine the effects in [Formula: see text] production in γγ collision and find that, in the favorable parameter spaces, the absolute values of the relative correction can be significantly large. We also estimate the new production process [Formula: see text], our results show that its cross-section can reach the level of a few fb for M = 150 GeV . A simply phenomenological analysis is also given for the decay modes T→ϕ+b and T→W+b. As long as the new T-quark is not too heavy, we conclude that this new channel might be used to test the LRTH model in the future ILC experiment.

PROBING NEW GAUGE BOSON Z′ FROM THE LEFT–RIGHT TWIN HIGGS MODEL AT HIGH-ENERGY e+e- COLLIDERS

The left–right twin Higgs (LRTH) model predicts the existence of the new neutral gauge boson Z′. In this paper, we calculate the contributions of this new particle to the processes e+e-→l+l-, [Formula: see text] and [Formula: see text] and study the possibility of detecting this new particle via these processes in the future high-energy linear e+e- collider (LC) experiments with [Formula: see text] and £ int = 340 fb-1, both for unpolarized and polarized beams. We find that the new gauge boson Z′ is most sensitive to the process [Formula: see text] with suitably polarized beams. As long as MZ′ ≤ 1.9 TeV , the absolute value of the relative correction parameter is larger than 5%. We calculate the forward–backward asymmetries for the process [Formula: see text], the results show that the possible signals of Z′ might be detected via measuring the deviations of A FB from its SM prediction for [Formula: see text]. Bounds on Z′ masses are also estimated within 95% confidence level. From our analysis, we conclude that the new gauge boson is most sensitive to the process [Formula: see text] and its virtual effects are most easy to be observed via this process in the future LC experiments.
