The environmental impacts of foreign direct investment (FDI) and trade have attracted much attention recently. This paper employs panel quantile regression to explore the effects FDI on Chinese provincial CO 2 emissions for period 1997‐2014. results indicate that effect is negative significant except at 5 th 10 quantiles. Foreign has a upper quantiles, degree increases gradually with increase emissions. also suggest inverted U‐shaped Kuznets curve (EKC) valid only in least most polluted...
Traditional Chinese medicine has been used for Coronavirus disease 2019 (COVID-19) as a therapeutic option. Lianhuaqingwen capsules (LHQW) are well-recognized their efficacy, while Kegan Liyan oral liquid (KGLY), widely influenza treatment, emerged promising candidate COVID-19 therapy. This trial aims to assess whether KGLY is non-inferior LHQW in treating mild COVID-19. A total of 127 participants (63 group and 64 group) were randomly allocated receive either therapy or 1:1 ratio. The...
The Least Squares Reverse Time Migration (LSRTM) can obtain high resolution and true amplitude imaging results. However, LSRTM for full model domain data requires simulation throughout the entire space, resulting in significant computational costs. In addition, Born approximation, which is based on single scattering theory, cause artifacts by treating multiple reflections from overburden as primary reflections. To address these issues, Marchenko redatuming method be used to separate...
Metal films perforated with two types of Sierpinski carpet patterns (SCP) are fabricated on silicon wafer, where one pattern possesses open square aperture as the building block and other has ring-shaped block. Enhanced transmissions observed in both structures. However, for SCP made apertures, resonance surface plasmon localized modes been identified. This feature does not exist apertures. finding provides an effective way to control extraordinary transmission through metal film fractal-like
The Marchenko method can retrieve Green’s functions among virtual sources in the subsurface and receivers at surface from single-sided reflection data. This process, called redatuming, allows estimation of full-wavefield information inhomogeneous subsurface. retrieved form input for creating image free artifacts caused by internal multiples. However, when using crosscorrelation imaging condition imaging, shallower regions obtained suffer reduced resolution due to unwanted interference, which...
Purpose In practical engineering, there are various sequences. The purpose of this paper is to improve and put forward a new model. Design/methodology/approach Based on the generalized accumulated generating operation, improved GM(1,1) cosine model proposed GAGM(1,1) Findings It found that can satisfy many kinds periodic sequences precision higher than Originality/value shows has important theoretic significance.
Identification of the different components from mixed fiber depends on parameter measurement fiber. As these are always overlapped or intersected in a magnified image obtained by microscope, appropriate processing technology is very important to realize segmentation. This paper firstly extracts contour, then finds all corner points contour. Accordingly concave found out ones means Vector Triangle Area Method. On other hand, skeleton also extracted, bifurcation chosen, and two judge rules...
Based on the generalized accumulated generating operation, in this paper GAGM(1,1) cosine model is proposed to improve classical GM(1,1) model. The can fit many kind of periodic sequences, such as non-equidistant sequences and with jump point or multi-stage. Also model's parameter space solving process are discussed details. At last used predict oil production. results showed that precision higher than confirmed has important theoretic practical significance.
When seismic waves propagate through the highly heterogeneous shallow layers, multiple orders of scattering will be developed along wave paths, leading to a very complex pattern on reflection data received by geophones surface. The scattered noise exhibits non-uniform shot gathers from near far offset over recording time. frequency content typically span entire band, greatly compromising quality data. In desert regions, serious heterogeneity surface sand layers contributes great much...
Using polymer droplets formed in dewetting of film on silicon surface as template, the columns capped with circular plates are fabricated via plasma etching. By blanket deposition a gold layer structure, an array metallic microcavities featured by metal plate separated column bottom is achieved. The geometrical parameters stereo structures can be tuned. We show that electric field at edge cap greatly enhanced, which used hot spot for trace amount chemical detection.
Local full-waveform inversion (FWI) methods use redatumed seismic responses of virtual receivers within the subsurface to build local objective function based on convolution-type representation theorem. The Marchenko method is widely used obtain data. only requires a smoothed velocity model with correct kinematic characteristics for redatuming single-sided reflection However, standard insensitive lateral propagation wavefield. By injecting wavefield along boundary target, modeling produces...
In the process of smoke detection, brightness and texture are varying in each frame, which brings interference to feature extraction reduces accuracy detection. this paper, adaptive learning rate model associated with those noise objects is established, provides a good regularization background adaptation for Gaussian Mixture Models (GMM). Next, linear fitting method combined motion shape features detect objects. Experiments have shown that algorithm can adapt illuminative changes various...
