Deep learning (DL) has exhibited huge potentials for hyperspectral image (HSI) classification due to its powerful nonlinear modeling and end-to-end optimization characteristics. Although the superior performance of DL-based methods been witnessed, some limitations can still be found. On one hand, existing DL frameworks usually resorted first-order statistical features, whereas they rarely considered second-order or higher order features. other complex hyperparameters (e.g., layer number...
An advanced enhanced oil recovery (EOR) method was investigated, employing a surfactant–polymer (SP) system in combination with viscosity reducer for application heavy reservoir within the Haiwaihe Block, Liaohe Oilfield, China. Significant advantages were observed through of LPS-3 (an anionic surfactant) and OAB (a betaine reducing interfacial tension enhancing emulsion stability, optimal results achieved at ratio 9:1. The BRH-325 polymer found to exhibit superior enhancement, temperature...
The Sichuan Basin is a prime gas-producing basin in China. Besides the giant Neoproterozoic Weiyuan gas field discovered central paleo-uplift, an extra reservoir Cambrian this area has been confirmed recent years. Although lower Paleozoic southwest (Weiyuan area) normally pressured, it overpressured (Moxi–Gaoshiti area). Combined with seal distribution, five pressure systems, including three overpressure can be divided based on drill-stem test, mud weight, and sonic transit time data....
The seasonal migration of the westerly jet (WJ) over East Asia is recognized as a substantial factor in historical climate region, especially regarding spatial and temporal variability regional rainfall dust cycle Northern Hemisphere. However, evolution Asian WJ since Last Glacial Maximum (LGM) remains debated. To enhance our understanding, we investigate changes sources sediments from southern Mariana Trench utilizing trace elements Sr-Nd isotopes.According to geochemical analyses, eolian...
Understanding the thermal evolution of sedimentary basins is critical to hydrocarbon accumulation, as it influences basin development, generation, migration, and formation source rocks reservoirs. While paleothermometry, primarily applied organic matter heavy minerals, has traditionally been standard method for reconstructing basin-scale histories, marine carbonate strata lack conventional paleothermometers, posing a significant challenge. Clumped isotope analysis, however, offers promising...
Background: Diabetic cardiomyopathy (DCM) is a prevalent complication observed in diabetic patients. The long non-coding RNA maternally expressed gene 3 (lncMEG3) has been found to be intricately associated with myocardial infarction and heart failure. However, the role of lncMEG3 DCM remains unclear. present study was designed investigate elucidate underlying molecular mechanisms. Methods: mouse model established through intraperitoneal injection streptozotocin (STZ). heart-targeted...
Lung cancer is the most common and leading cause of death in China, as well world. Late diagnosis main obstacle to improving survival. Currently, early detection methods for lung have many limitations, example, low specificity, risk radiation exposure overdiagnosis. Exhaled breath analysis one promising non-invasive techniques cancer. The aim this study identify volatile organic compound (VOC) biomarkers construct a predictive model based on exhaled analysis.The will recruit 389 patients...
Under the combined impact of climatic, socioeconomic, and environmental factors, vegetation NPP change process its responses to drive factors in sub-regions Mainland China are not clear. This study analyzes changing pattern from 2000 2022 perspective zoning clarifies response mechanism climate-human interaction based on gravity center model, third-order partial correlation coefficient geographical detector. The results showed that: (1) There was an overall decreasing trend southeast...
The Gasi reservoir in the Qinghai oilfield is a typical high-temperature and high-salinity reservoir, with an average temperature salinity of 70.0 °C 152,144 mg/L, respectively. For over 30 years since 1990, water flooding has been primary method for enhancing oil recovery. Recently, turned into mature oilfield. It possesses high cut 76% total recovery rate 47%. However, main developing enhanced (EOR) technology development next stage yet to be determined. Surfactant–polymer (SP) flooding,...
Most of the previous studies exploring changing patterns wetland in Yellow River Delta (YRD) were conducted based on sparse time-series images, which ignored its severe environmental gradient and rapid evolution process wetland. The changes dominant factors YRD are not clear. This study used dense Sentinel-2 images to establish a database YRD, then analyzed spatial distribution characteristics of, temporal in, during 2015–2022. Finally, spatio-temporal evolutions explored revealed. results...
Abstract We re-evaluate the Raman spectroscopic quantification of molar ratio and pressure for CH 4 –CO 2 mixtures. Firstly, factors CO increase with rising at room temperature, indicating that /CO can be applied to those fluid inclusions (FIs) high internal (i.e., > 15 MPa). Secondly, v 1 (CH ) peak position shifts lower wavenumber increasing constant confirming used calculate pressure. However, this method should carefully calibrated before applying FI analyses because large...
The temperature history of samples and maximum palaeogeothermal profiles boreholes were reconstructed based on low‐temperature thermochronology vitrinite reflectance data, the results provide limits for timescale amount uplift–denudation eastern Sichuan Basin. thermal showed that uplifting cooling Basin began around Late Cretaceous (approximately 100–80 Ma). region had experienced a continuous process from until present, with geothermal gradient decreasing 32–36 °C/km to 20–23 °C/km....
