We present the first catalog of very-high energy and ultra-high gamma-ray sources detected by Large High Altitude Air Shower Observatory (LHAASO). The was compiled using 508 days data collected Water Cherenkov Detector Array (WCDA) from March 2021 to September 2022 933 recorded Kilometer Squared (KM2A) January 2020 2022. This represents main result most sensitive large coverage survey sky above 1 TeV, covering declination $-$20$^{\circ}$ 80$^{\circ}$. In total, contains 90 with an extended...
Abstract Aims Intensive soybean/maize intercropping, a specific form of holds promise in addressing the challenges posed by increasing food demands, diminishing cropland areas, deteriorating soil quality, and escalating environmental pollution. Methods To evaluate potential this system, we conducted national meta-analysis, quantifying its absolute yield gain (net effect, NE) land use efficacy (land equivalent ratio, LER). We further investigated underlying mechanisms examining local climate,...
Abstract The first source catalog of the Large High Altitude Air Shower Observatory (LHAASO) reported detection a very high energy gamma-ray source, 1LHAASO J1219+2915. This Letter presents further detailed study spectral and temporal behavior this pointlike source. best-fit position TeV (R.A. = 185.°05 ± 0.°04, decl. 29.°25 0.°03) is compatible with NGC 4278 within ∼0.°03. Variation analysis shows an indication variability on timescale few months in band, which consistent low-frequency...
Automatic monitoring of feeding behavior especially rumination and eating in cattle is important to keep track animal health growth condition disease warnings. The noseband pressure sensor not only able accurately sense the change cattle's jaw movements, which can directly reflect chewing behavior, but also has strong resistance interference. However, it difficult same initial while wearing sensor, this will pose a challenge process data. This article proposed machine learning approach...
Surface vegetation has a substantial impact on soil aggregate stability, which is an important indicator of quality. However, there still limited research the response stability indicators and organic carbon, total nitrogen, phosphorus content in aggregates for different patterns rocky desertification fragile ecological areas. Therefore, order to study effects restoration models related nutrient their promoting relationships karst areas southwest China, samples under three artificial...
The identification and monitoring of cyanobacterial blooms (CBs) is critical for ensuring water security. However, traditional methods are time-consuming labor-intensive not ideal large-scale monitoring. In operational monitoring, the existing remote sensing also due to complex surface features, unstable models, poor robustness thresholds. Here, a novel algorithm, pseudo-Forel-Ule index (P-FUI), developed validated identify based on Terra MODIS, Landsat-8 OLI, Sentinel-2 MSI, Sentinel-3 OLCI...
Soil erosion poses a global threat to arable land and its sustainability, particularly in China, where the most severe soil exists worldwide. No-tillage (NT) mulching (NTS) are considered effective management techniques for reducing erosion, but only 10% of area utilizes them. Therefore, comparison conventional tillage (CT), we conducted comprehensive national assessment NT NTS evaluate their impact on water across China’s croplands period spanning 2000 2018, through using Revised Universal...
Algal blooms are the vertical movement of algae and three-dimensional redistribution biomass based on a certain amount. Compared with algal bloom area, is more stable can reflect eutrophication water body scientifically. How to estimate accurately, stably, quickly currently lacking sufficient research or evaluation. This paper proposed machine algorithm Moderate Resolution Imaging Spectrometer (MODIS) data measure inland eutrophic bodies, which was successfully applied typical lake in China...
One of the primary challenges our time is to feed a growing and more demanding world population with degraded soil environments under variable extreme climate conditions. Conservation tillage (CS) deep (DT) have received strong international support help address these but are less used in major global food production China. Hence, we conducted large-scale literature search English Chinese publications synthesize current scientific evidence evaluate effects CS DT on protection yield...
Abstract In this study, the data of typical paddy fields from 63 soil series hydragric anthrosols (paddy soil) and 26 under tobacco-rice rotation in Huan province China were used to assess current thickness plough layers fields, set up criterion deep-ploughing (30 cm study) feasibility for predict possible changes nutrient contents new after deep-ploughing. The results showed that mean Ap1 was 15.3 cm, 93.2% lower than ideal depth 20 cm. established by comparing textures bulk densities...
The Southern Wide-field Gamma-ray Observatory (SWGO) is an international collaboration working on a ground-based gamma-ray observatory that will be located in the southern hemisphere. A crucial step analysis to identify showers produced by gamma rays and separate them from abundant background of hadronic showers. In this work, we propose adapt observable $S_b$ used successfully composition studies Pierre Auger SWGO detector. This takes into account signal position each triggered It...
