Analysis of Natural Hydraulic Fracture Risk of Mudstone Cap Rocks in XD Block of Central Depression in Yinggehai Basin, South China Sea

Energies, 2021
The Yinggehai Basin is an important Cenozoic gas bearing basin in the South China Sea. With the gradual improvement of gas exploration and over-development in shallow layers, deep overpressured layers have become the main target for natural gas ...

Differences in the key volatile organic compound species between their emitted and ambient concentrations in ozone formation [PDF]

Atmospheric Chemistry and Physics
The emissions and secondary transformations of volatile organic compounds (VOCs) play a significant role in ozone (O3) formation. Previous studies have often relied on ambient VOC concentrations to identify key species.

Evolution of Miocene Submarine Fan Systems in the Northern Lingshui Sag, Qiongdongnan Basin, South China Sea

Journal of Marine Science and Engineering
The Miocene Sanya, Meishan, and Huangliu formations in the Qiongdongnan Basin (QDNB) record a complete evolutionary history of submarine fan systems, yet a continuous Miocene-scale depositional framework has not been established for the Northern Lingshui

Spatial differentiation of submarine fans and distribution patterns of high-quality reservoirs in Miocene Meishan Formation, block 13-2, Lingshui Sag, Qiongdongnan Basin

Shiyou shiyan dizhi
Since the discovery of high-yield gas flows from the Miocene Meishan Formation in well LS13-C of block 13-2 in the Lingshui Sag, Qiongdongnan Basin, subsequent exploration drilling has failed to achieve commercial breakthroughs.

Identification of a differentially expressed gene, ACL, between Meishan × Large White and Large White × Meishan F1 hybrids and their parents

Genetics Selection Evolution, 2008
ATP-citrate lyase (ACL), one of the lipogenic enzymes, catalyses the formation of acetyl-coenzyme A (CoA) involved in the synthesis of fatty acid and cholesterol. In pig, very little is known about the ACL gene.

CONODONT BIOSTRATIGRAPHY AND LITHOSTRATIGRAPHY ACROSS THE PERMIAN-TRIASSIC BOUNDARY AT THE LUKAC SECTION IN WESTERN SLOVENIA

Rivista Italiana di Paleontologia e Stratigrafia, 2011
Detailed conodont biostratigraphy and lithostratigraphy of the Late Permian and Early Triassic beds were studied at the LukaC section in western Slovenia. The analyzed section is composed of the Bellerophon Formation ("evaporite-dolomite member") and the

Fault characteristics and their control on accumulation in block LS13-2 of Lingshui Sag, Qiongdongnan Basin

Shiyou shiyan dizhi
In the northern part of the Qiongdongnan Basin, the block LS13-2 of the Lingshui Sag is the only exploration area in the Meishan Formation known to have natural productivity, representing an accumulation model of source in the lower section and reservoir

Investigation of gas-bearing properties of "bright spot"-type reservoirs in the Miocene Meishan Formation, Qiongdongnan Basin

Shiyou shiyan dizhi
The Miocene Meishan Formation is the main hydrocarbon-bearing interval in the Lingshui Sag, Qiongdongnan Basin. Its overall exploration degree is relatively low, and its hydrocarbon exploration potential is significant.

Intelligent recognition algorithm for rice diseases in farmland based on multileaf segmentation

Agronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Timely and accurate identification of specific types and development trends of rice (Oryza sativa L.) diseases in farmland is a critical prerequisite for implementing scientific control measures and reducing yield losses. Aiming at the problem of low recognition accuracy for rice diseases in farmland under natural lighting conditions, this ...
