Ground-penetrating radar (GPR) has been regarded as a potentially efficient way of evaluating the growth status trees and preventing deterioration associated with trunk defects. The majority current GPR data inversions, however, focused on imaging macroscale location As first attempt to seek preferable quantitative inversion methodology for specifying tree protection remedies, this article proposes full-waveform (FWI) approach involving dual-parameter attributes applied common-offset from...
Improving the accuracy and efficiency of numerical simulation ground penetrating radar (GPR) becomes a pressing need with rapidly increased amount inversion data growing demand for migration imaging quality. In this article, we present spectral element time-domain (SETD) procedure GPR forward modeling further apply it to reverse time (RTM) complex geoelectric models. This approach takes into account flexibility finite methods high precision methods. Meanwhile, in procedure, frequency shifted...
With the outbreak of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), coronaviruses have begun to attract great attention across world. Of known human coronaviruses, however, Middle East coronavirus (MERS-CoV) is most lethal. Coronavirus proteins can be divided into three groups: nonstructural proteins, structural and accessory proteins. While number each these varies greatly among different are closely related pathogenicity virus. We found for first time that ORF3 protein...
High thermal conductivity liquid crystal epoxy resins (LCERs) and their composites are essential for efficient management in electronic devices. The production of LCERs currently depends on combining monomers hardeners or catalysts. However, these curing agents catalysts destroy the phase crosslinked network, thereby limiting LCERs. Here, a novel self-curing strategy is developed by incorporating Schiff base into monomers, enabling without additional This method effectively retains ordered...
Point clouds are subject to various distortions during point cloud processing missions, any of which may lead quality degradation. Consequently, predicting has attracted a lot attention. In this paper, layered projection-based metric (LP-PCQM) is proposed. We layer the distorted and its original version firstly then extract geometry color features layers. The feature obtained using method extracted upon RGB by point-based method. Finally, LP-PCQM weighted linear combination an optimal subset...
Reverse time migration (RTM) has the advantage of high-precision imaging, and it can converge radar wave back to its actual position, making widely used in exploration. However, there are artifacts, low-frequency noise fuzzy deep imaging RTM results. Researchers have proposed full wavefield separation condition total variation (TV) technique, both which could suppress artifacts. original method was considerably limited by extensive calculation, cannot solve problem weak energy zone;...
Due to the unique adsorption and desorption characteristics of coal, coal reservoir permeability changes dynamically during coalbed methane (CBM) development. Coal reservoirs can be classified using a dynamic characterization in different production stages. In single-phase water flow stage, four demarcating pressures are defined based on damage from effective stress permeability. into vulnerable, alleviative, invulnerable reservoirs. gas two used quantitatively characterize recovery...
Matrix metalloprotease (MMP) is the key endogenous protease that boosts autolysis of sea cucumber, while its action and mechanism in vivo are still unclear. MMP inhibitor (1,10-phenanthroline) was injected into coelomic cavity cucumber (Stichopus japonicus) effects on were investigated for first time by using scanning electron microscopy, multi-functional imaging system, confocal laser microscopy. In response to external stimuli, level Ca2+ live dermis increased, which may activate activity....
A reliable inspection of the tree trunk internal defects is often considered vital in health condition assessment for living tree. There has been a desire to reconstruct structure quantitatively using non-destructive testing technology. This paper intends apply wavefield reconstruction inversion (WRI) obtain high-precision information from detection ground penetrating radar data. The variational projection method and grouped multi-frequency strategy are adopted strengthen algorithm stability...

The coseismic slip on the main fault related to 2017 Iran-Iraq Mw7.3 earthquake has been investigated by previous studies using DInSAR (differential interferometric synthetic aperture radar) ground deformation measurements. However, observation is not sensitive in along-track (AT) direction. Therefore, only one-dimensional (1D) field measurements, derived LOS (line-of-sight) direction of radar, was applied source parameters estimation. To further improve accuracy inversion, 3D...
The influence of interphase on the level and distribution thermal residual stress (TRS) in SiCp/6061Al composites was studied by using a three-dimensional (3D) interface-phase model. expansion coefficient elastic modulus components were main factors affecting TRS composites. formed SiC-MgO-6061Al has highly concentrated TRS, SiC-Si-6061Al had lowest level. With increase thickness, for most components, showed trend first decreased then increased. When thickness 1.2 μm, it SiC particle aspect...
Symbiosis of marine algae is inevitable in the environment, and species may occur interaction on growth. In this study, macroalgae Ulva pertusa microalgae Heterosigma akashiwo were selected as target to study mechanism between them. After 8 days co-cultivation, inhibition growth was observed for both U.
