In this paper, the performance of C-band synthetic aperture radar (SAR) Gaofen-3 (GF-3) quad-polarization Stripmap (QPS) data is assessed for classifying late spring and summer sea ice types. The investigation based on 18 scenes GF-3 QPS acquired in Arctic Ocean 2017. study, floe (FI), brash (BI) between floes open water (OW, ice-free area) were classified a mini residual convolutional network, which we call MSI-ResNet. While investigating optimal patch size MSI-ResNet, found that, as...
Despite the rapid development of China's digital economy and many studies involving economy, there is no unified standard on measurement existing accounting methods all have certain shortcomings. In view this, this paper constructs a set system to measure scale industry, from perspective industrialization industrial digitization, based input-output tables. We separate traditional industries by splitting merging IO tables using data such as Economic Census Yearbook SAT calculate industry....
The presence or absence of sea ice introduces a substantial perturbation to surface‒atmosphere energy exchanges. Comprehending the effect varying cover on interactions is an important consideration for understanding Arctic climate system. recurring North Water Polynya (NOW) serves as natural laboratory isolating cloud responses rapid, near-step in ice. In this study, we employed high-resolution System Reanalysis version 2 (ASRv2) data estimate turbulent heat fluxes over NOW and...
The mid-depth ocean circulation is critically linked to actual changes in the long-term global climate system. However, past few decades, predictions based on models highlight lack of data, knowledge, and implications change assessment. Here, using 842,421 observations produced by Argo floats from 2001-2020, Lagrangian simulations, we show that only 3.8% oceans, including part equatorial Pacific Ocean Antarctic Circumpolar Current, can be regarded as accurately modelled, while other regions...
Abstract. Using satellite observations from 2003 to 2020 and cruise 2019 2021, this study reveals an unexpected minor role of upwelling in seasonal interannual variations chlorophyll a (Chl a) concentrations the coastal region east Hainan Island (UEH) northwestern South China Sea (NWSCS). The results show strong variability Chl concentration core area UEH. Different strongest summer, UEH reaches maximum 1.18 mg m−3 autumn winter, with minimum value 0.74 summer. summer increases as high 1.0...
In this paper, the sea surface wind speed (SSWS) retrieval from Gaofen-3 (GF-3) quad-polarization stripmap (QPS) data in vertical-vertical (VV), horizontal-horizontal (HH), and vertical-horizontal (VH) polarizations is investigated detail based on 3170 scenes acquired October 2016 to May 2018. The radiometric calibration factor of VV polarization examined first. This generally meets requirement SSWS accuracy with an absolute bias less than 0.5 m/s but shows highly dispersed characteristics....
This study evaluated three satellite precipitation products, namely, TRMM, CMORPH, and PERSIANN, over the Three Gorges Reservoir area in China at multiple timescales. The assessment covered following aspects: rainfall amount, extreme precipitation, rainy-day detection ability. Results indicated that CMORPH TRMM estimates of amount were reasonably good, but PERSIANN showed a larger bias than other two products. data precision was slightly better TRMM. All products could reproduce diurnal...
Geothermal resources have significant development and usage potential. It is critical to conduct geological investigation of geothermal prior mining, so as deepen our knowledge comprehension resources. Ground water heated by magmatic rocks can be created in rock areas. However, their communication weak, the depth burial typically great. difficult for traditional geophysical methods, such induced polarization method, achieve useful exploration depths, they low accuracy. In this article, a...
When magmatic rock intrudes a coal seam, it destroys the seam's structure, reduces quality, and brings hidden dangers to safe production processes of mine. In this study, mechanism intrusion into seams was briefly described. addition, changes in composition, geophysics characteristics following were summarized. This study also performed forward modeling performed. Then, effectiveness seismic attributes detecting ranges intruded by rocks theoretically analyzed. It observed that after seams,...
Ficus hirta Vahl. (FHV) is widely consumed because of its functional and aromatic compounds. The incorporation adjuncts contributes to the flavor properties beers. This study aims enrich FHV extractions develop beers with satisfactory physicochemical, antioxidant, sensory characteristics. As a result, 0.1 g/mL (P1) 0.067 (P3) extraction showed highest values physicochemical including °Brix, antioxidant activity, foam, lightness, color intensity. Electronic nose tongue results show that aroma...
In order to measure the scale and development trend of China's inter-provincial digital economy, this paper calculates economy core industries added value four different categories 30 provinces in China from 2007 2017 based on division standard National Bureau Statistics. results more accurately reflect characteristics each province's industrial structure, uses input-output tables than 100 departments province 2007, 2012 data Economic Census Yearbook split non-digital parts industry. The...
Egocentric action anticipation aims at predicting the near future based on past observation in first-person vision. While actions may be wrongly predicted due to dataset bias, we present a counterfactual analysis framework for egocentric (CA-EAA) enhance capacity. In factual case, can predict upcoming visual features and semantic labels from observation. Imagining one situation where no representation had been observed, would obtain only using labels. this way, reduce side-effect caused by...
The Duolong mineral district in western Tibet is one of the largest porphyry Cu–Au deposit fields with significant metallogenic potential China. Its tectonic environment relevant to Early Cretaceous mineralization remains controversial. Here we report new whole-rock major and trace element, Sr-Nd-Hf-Pb isotopic data for newly discovered basalt Nadun area, district, decipher their genesis further constrain environment. A contemporaneous rhyolite sample interbedded lower part volcanic section...
Biomechanical properties of corneal scar are strongly correlated with many diseases and some types surgery, however, there is no elasticity information available about to date. Here, we proposed an acoustic radiation force optical coherence elastography system evaluate elasticity. Elasticity quantification was first conducted on ex vivo rabbit corneas, the results validate efficacy our system. Then, experiments were performed human scarred cornea, where structural features, elastic wave...
The aim of this article was to investigate the potential polarimetric decomposition Chinese Gaofen-3 (GF-3) C-band fully synthetic aperture radar (PolSAR) data for Arctic sea ice classification during summer season. Five different approaches, including Cloude-Pottier (Cloude), Freeman three-component (Freeman3), using extended Bragg model (Freeman3X), Yamaguchi (Yamaguchi3), and nonnegative eigenvalue (NNED) were analyzed 35 scenes GF-3 PolSAR collected over Fram Strait, from June 14–18,...

The Bailingshan complex is located to the south of Jueluotage tectonic belt Eastern Tianshan, consisting quartz monzodiorite, granodiorite, monzogranite, and granite. Mafic microgranular enclaves (MME) are commonly found in granodiorites monzogranites have sharp contacts with host rocks. Sometimes, fine veins rocks cut through enclaves. MMEs mainly fine‐grained dioritic rocks, including diorite pyroxene igneous textures, having condensing edges rich dark minerals. Among enclaves, orthoclase...

Researchers agree that there are two main causes to sea-level rise: melting of land-ice and thermal expansion ocean water due global climate warming. However exist several secondary can result in sea level rise, which used be ignored. In this study we firstly qualitatively analyzed reasons also cause rise such as land reclamation projects, coastal erosion, river sediment, so on. Then a mathematical model was built, by the quantitatively estimated rates caused sediment all terrestrial...
The wind wake on the lee side of Hainan Island in winter covers southwest entrance Beibu Gulf (or Tonkin) and is essential to regional ocean dynamics. Using multiple satellite observations including advanced synthetic aperture radar (ASAR), we revisited process during 2011. Asymmetric oceanic thermal responses were found with a warm band expanding northwestwardly while cold tongue formed southeast. Combining observations, model simulations, reanalysis data, heat advection terms (ADV) are...
