The experimental results showed that the ratio of the impact force of the cube to the sphere was mostly between 1.2 and 2.0 and that of the cuboid to the sphere was mostly between 1.0 and 1.5. Combined with our fitting formula, the contact area of the square and cuboid rockfall used by ...
Henan Province, situated in the central part of China, is a developing region with a population density of approximately 595 individuals per square kilometer and a permanent resident count of 98.72 million. It ranks third in terms of population size in China and has one of the highest carbon ...
The manuscript “Credibility of results in emotion science: A z-curve analysis of results in the journals Cognition & Emotion and Emotion” (CEM-DA.24) presents results from a z-curve analysis on reported statistics (t-tests, F-tests, and chi-square tests with df < 6 and 95% confidence ...
Wildfire burns between3.94 million and 5.19 million square kilometresof land every year worldwide. If that area were a single country, it would be the seventh largest in the world. In Australia, most fire occurs in the vast tropical savannas of the country’s north. Innew researchpublished in...

Thus there exists a non-trivial collection of these vectors that sums to zero, which implies that the corresponding elements of the sequence multiply to a square. From (1), (2) we can find sequences of -smooth numbers in , with each sequence being to the right of the previous sequence...
Statistical analysis performed using Student’s t-test and Chi-square. Results: Median age 60 years (37–87 yrs). 139 (88.5%) screen-detected cases; 142 (90.4%) had mammographic calcification. 111 (70.7%) had high-grade DCIS, 89 (56.6%) had comedonecrosis. Out of 157, 101 (64.3%) ...
Several quantitative techniques such as classic Ordinary Least Square (OLS), Genetic Algorithm (GA), Harman's single-factor test, Probit estimation, multivariate regression and simulation are used to observe competencies and skills for the coexistence of worker-AI in the workplace. Table 3. ...
The Knight-Alzheimer Disease Research Center (Knight-ADRC) at Washington University in St. Louis has pioneered and led worldwide seminal studies that have expanded our clinical, social, pathological, and molecular understanding of Alzheimer Disease. Over
The error of improving public sports effect under exercise intervention is divided into mean square error Em and relative error percentage EC. Em is the error between the estimated value and the actual value, reflecting the overall error of the result; EC is the error percentage of a single ...
