The ability to accurately and rapidly acquire leaf area index (LAI) is an indispensable component of process-based ecological research facilitating the understanding gas-vegetation exchange phenomenon at array spatial scales from landscape. However, LAI difficult directly for large extents due its time consuming work intensive nature. Such efforts have been significantly improved by emergence optical active remote sensing techniques. This paper reviews definitions theories measurement with...
The last two decades have witnessed increasing awareness of the potential terrestrial laser scanning (TLS) in forest applications both public and commercial sectors, along with tremendous research efforts progress. It is time to inspect achievements remaining barriers TLS-based investigations, so further application are clearly orientated operational uses TLS. In such context, international TLS benchmarking project was launched 2014 by European Spatial Data Research Organization coordinated...
Abstract Growing urban population and the distinct strategies to accommodate them lead diverse development patterns worldwide. While local evidence suggests presence of signatures in rainfall anomalies, there is limited understanding how responds divergent Here we unveil a divergence exposure extreme for 1790 inland cities globally, attributable their respective patterns. Cities that experience compact tend witness larger increases frequency over downtown than rural surroundings, while...
We present the point cloud slicing (PCS) algorithm, to post process data (PCD) from terrestrial laser scanning (TLS). then test this tool for forest inventory application in urban heterogeneous forests. The methodology was based on a voxel structure derived TLS PCD. retrieved biophysical tree parameters including diameter at breast height (DBH), height, basal area, and volume. Our results showed that TLS-based metrics explained 91.17% (RMSE = 9.1739 cm, p < 0.001) of variation DBH...
Terrestrial laser scanner (TLS)-based leaf area index (LAI) retrieval is an appealing concept, due to the ability capture structural information of canopies as 3-D point cloud data (PCD). TLS-based LAI estimation methods promise a nondestructive tool for spatially explicit calibration estimated by aerial or satellite remote sensing techniques. These also overcome sky condition restrictions on-ground optical instruments such hemispherical photography frequently used estimation. This paper...
Accurate separation of photosynthetic and nonphotosynthetic components in a forest canopy from 3-D terrestrial laser scanning (TLS) data is challenging but key importance to understand the spatial distribution radiation regime, processes, carbon water exchanges canopy. The objective this paper was improve current methods for separating TLS canopies by adding two additional filters only based on its geometric information. By comparing proposed approach with eigenvalues plus color...
Tree leaf orientation, including the distribution of inclinational and azimuthal angles in canopy, is an important attribute forest canopy architecture critical determining within below solar radiation regimes. Characterizing orientation a key step to retrieval area index (LAI) based on remotely sensed data, particularly discrete point data such as that provided by light detection ranging. In this paper, we present new method indirectly nondestructively retrieves foliage elements' from cloud...
Abstract Determining oil slick thickness plays an important role in assessing spill volume and its environmental impacts on the ocean. In this study, we used a Hyperion image of accident area seawater fresh crude samples collected Bohai Sea China. A well-controlled laboratory experiment was designed to simulate spectral responses different thicknesses. Spectral resampling normalization methods were reduce differences reflectances between experimental background sample real seawater. Fitting...
Quantifying the 3-D forest canopy structure and leaf area index of an individual tree or a stand is challenging. The structural information implicitly contained within point cloud data (PCD) generated from terrestrial laser scanning (TLS) makes it possible to characterize directly spatial distribution foliage elements. In this paper, new voxel-based method titled "point slicing" presented retrieve biophysical characteristics including extinction coefficient, gap fraction, overlapping effect,...
Zheng, which is also called a syndrome or pattern, the basic unit and key concept of traditional Chinese medicine (TCM) theory. Zheng can be considered further stratification patients when it integrated with biomedical diagnoses in clinical practice to achieve higher efficacies. In an era evidence-based medicine, confronted vast increasing volume TCM data, there urgent need explore these resources effectively using techniques knowledge discovery databases. The application effective data...
Forests play a critical role in mitigating climate change because of their high carbon storage and productivity. China has experienced pronounced increase forest area resulting from afforestation reforestation activities since the 1970s. However, few comprehensive analyses have been made to assess recent dynamics biomass sinks China's forests. This study refined forests based on eight inventories 1973 2013. These increased 25.0 166.5 Tg C yr−1 between 2008, then decreased 130.9 for period...
Different oil spill pollution types could be produced in transport and weathering processes. Investigation of these is beneficial for recovery processing. Optical remote sensing techniques play an important role marine monitoring have the ability to identify different types. Recently, research on optical has made much progress detecting targets, identifying spectral response characteristics, formulating theories. Floating black oil, slicks, oil-water mixture accidents are main targets...

The spatial distribution of the photosynthetic components a forest canopy plays key role in ecological related processes such as gas exchange, photosynthesis, and evapotranspiration through affecting radiation regimes canopy. However, quantitative evaluation woody materials' contribution to effective leaf area index (LAIe) using 3-D terrestrial laser scanning (TLS) is challenging work. In this paper, we first identified differences between directional gap fraction (DGF) angular (AGF) then...
The scan angle information implicitly contained within the 3-D point cloud data (PCD) generated from light detection and ranging strongly affects retrieval accuracy of forest canopy structural parameters. Using overlapping aerial laser scanning (ALS) flight paths with multiple angles over a can help to remove occlusion effects between foliage elements, ultimately creating relative comprehensive PCD.

Separating foliage and woody components can effectively improve the accuracy of simulating forest eco-hydrological processes. It is still challenging to use deep learning models classify canopy from point cloud data collected in forests by terrestrial laser scanning (TLS). In this study, we developed a convolution neural network (CNN)-based model separate (FWCNN) combing geometrical return intensity (LRI) information local sets TLS datasets. Meanwhile, corrected LRI proposed contribution...
Using different explants of in vitro seed grown Scutellaria baicalensis Georgi plantlets, hairy roots were induced following inoculation Agrobacterium rhizogenes strains A4GUS, R1000 LBA 9402 and ATCC11325. The A4GUS proved to be more competent than other the highest transformation rates observed cotyledonary leaf explant (42.6 %). transformed appeared after 15-20 d incubation on hormone free Murashige Skoog medium.

One important concept in traditional Chinese medicine (TCM) is "treating different diseases with the same therapy". In TCM practice, some patients Rheumatoid Arthritis (RA) and other Coronary Heart Disease (CHD) can be treated similar therapies. This suggests that there might something commonly existed between RA CHD, for example, biological networks or basis. As amount of biomedical data leading databases (i.e., PubMed, SinoMed, etc.) growing at an exponential rate, it possible to get...
