(2) Little research has been conducted on the spatio-temporal dynamic evolutionary pathways, evolutionary laws, and driving mechanisms of ecological welfare performance. (3) The mainstream measurement method, the DEA model, does not take into account the influence of random factors, which makes the...
The induction equation is an evolutionary equation for the magnetic field 𝐁B. For a perfect electrical conductor, 𝜎→∞σ→∞, i.e., 𝜂→0η→0. This limit defines the so-called ideal Magnetohydrodynamics (MHD), and the induction equation becomes ∂𝐁∂𝑡=∇×(𝐮×𝐁)...
A flat-topped peak gives researchers a chance to identify new species and unlock secrets of evolution. The biggest challenge: getting there.
Evolutionary strategy is frequently used in human-in-the-loop control as it can manage many objective functions41. However, objective functions based on measurements of human performance typically require a mass of online and offline calculations, making it a lengthy evaluation period50. To improve ...
Changing climates in the past affected both human and faunal population distributions, thereby structuring human diets, demography, and cultural evolution. Yet, separating the effects of climate-driven and human-induced changes in prey species abundances
2018), both by dynamic competitive equilibrium models (Jovanovic 1982; Ericson and Pakes 1995) and evolutionary theory (Nelson and Winter 1982; Dosi et al. 1995). In our empirical setting, PRODUCTIVITYg, where g = {L, M, H}, is proxied by the ratio of sales to employees, ...

[125], which may contribute to their pleiotropy in functional activity between cell types and stages of development, thereby increasing evolutionary sequence constraints [1,126]. Despite high sequence conservation, mutagenesis at many of these regions does not lead to embryonic lethality, which ...
What kind of temporal and spatial characteristics and evolutionary trends does the HQD of city clusters show? How can the HQD of city clusters be promoted under the goal of modernization? The scientific answers to the above questions are of great practical significance to the construction of city...
Evolutionary Approaches (EA), Swarm intelligence (SI) approaches, and Physics-based Approaches (PHA) are the classes of metaheuristic approaches. SI approaches are a group inspired by swarms and animals’ behavior habits [13]. Multiple SI methods have been proposed in the literature and above. Th...
