Researchers used repeating microearthquakes to estimate the deep slip rate of the Lijiang-Ninglang fault, yielding a value of 5 mm/yr at 23 km depth. This discovery provides a new method for inferring slip rates along active faults and sheds light on earthquake recurrence.
This study measured contrast sensitivity in individuals with different levels of visual acuity, revealing stark differences in color frequency and brightness. The results showed that contrast sensitivity values increased significantly as visual acuity improved, particularly for spatial frequencies above 1 cpd.
Phycologists and algal biotechnologists in China are addressing pressing issues in algae research, including resource exhaustion and environmental impact. The country's largest seaweed cultivation industry has become a crucial driver of innovation and growth in the field.
The study analyzed the angular rotation of gecko joints during locomotion on horizontal surfaces, revealing spatio-temporal rotation trajectories. It also compared the movement patterns of geckos on vertical walls, showing differences in joint angles and limb phases.
Researchers used a VHF radio interferometer system to study cloud-to-ground lightning flashes, revealing new characteristics and progression speeds of different types of leaders. The system allows for microsecond-order time and space reconstruction, enabling detailed analysis of lightning flash processes.
Researchers detected large gas reservoirs in mid-crust rocks using seismic method, contradicting conventional wisdom about gas-anomaly locations. Gas-filled tiny fissures in rocks cause significant decrease in seismic wave velocity.
The study found that magnetized water exhibits magnetism, a saturation effect, and memory properties. New phenomena, such as irreversible infrared absorption and exponential UV absorption, were also discovered. These findings support the theory of magnetization of water proposed by Professor Pang Xiao-Feng.
This special issue explores the fundamental research of new-generation Internet architecture, addressing major technical challenges such as scalability, security, and high-performance. The studies aim to provide theoretical foundations and scientific-proof support for solving these challenges and carry out technological innovation.
Papers in this special issue cover data analysis and investigations of the Double Star Program, as well as CMEs, Solar wind, and magnetosphere topics. The conference brought together prominent researchers, including Z.X.LIU and S.T. WU, to share their latest findings on solar and magnetospheric physics.
Scientists have discovered a new mineral, xieite, with a post-spinel structure in the Suizhou meteorite. The mineral is a high-pressure polymorph of chromite-spinel with a density about 10% denser than chromite.
This study investigates the 3D rupture conformations of a surface fault under biaxial compression, revealing three stages of crack growth and introducing the concept of anti-wing cracks. The results provide fundamental understanding of surface fault propagation and have significant implications for future studies on active fault movement.
Numerical simulations of nutrient transport changes in Honghu Lake Basin revealed that human activities increased rapidly and became a dominant factor in changes of the nutrient transportation. The study found variations in nutrient production and concentration, with increasing rates of eutrophication over time.
The coercivity mechanism of HDDR Nd-Fe-B permanent magnetic alloy is greatly related to its microstructure defect at the grain boundary, according to the study. For a fixed lex, coercivity reaches maximum at 2r0/lex=1.67, controlled by pinning and nucleation mechanisms.
The study reveals that the Liujiang brain shares morphological features with modern humans, including a round shape and enlarged frontal lobes. The virtual endocast also shows a high brain capacity, suggesting a Late Homo sapiens classification.
Researchers have discovered wheel-shaped structures with octa- and enneacoordinate planar cobalt, iron and nickel centered in perfect octagonal and enneagonal boron rings. The stability of these structures is attributed to the contribution from two kinds of orbitals, resulting in aromaticity with six delocalized p electrons.
The discovery of Eoconfuciusornis zhengi provides evidence for the evolution of Confuciusornithidae family and its link to early avian flight. The fossil's unique features, such as increased deltopectoral crest size and keel, indicate a significant adaptation for improved flight capabilities.
The study found that key codons responsible for antigenic drift were identified in the HA1 gene of H3N2 influenza viruses. The mutations occurred over eight flu seasons and affected four times of antigenic drift in Fujian, China.
