A Scalar Field Dark Matter Model and Its Role in the Large-Scale Structure Formation in the Universe by Mario A. Rodríguez-Meza

“…With this scalar field dark matter model we study the non-linear evolution of the large-scale structures in the universe. The equations that govern the evolution of the scale factor of the universe are derived together with the appropriate Newtonian equations to follow the nonlinear evolution of the structures. …”

The Impact of Capital Structure on the Performance of Chinese E-Commerce Industry Companies (2013–2019 Panel Data) by Meng-Yao Zhang, Li-Wei Lin, Huei-Ping Chen, Xuan-Ze Zhao

“…This research examined how to estimate performance in China’s e-commerce industry, by taking 2013–2019 e-commerce listed companies as the research samples and using an empirical research method to study the relationship between capital structure and firm performance. The empirical results show that the debt-to-asset ratio and the long-term interest-bearing debt ratio have a negative impact on firm performance, but the impact of the long-term interest-bearing debt ratio is not significant. …”

Improved 2D Discrete Hyperchaos Mapping with Complex Behaviour and Algebraic Structure for Strong S-Boxes Generation by Musheer Ahmad, Eesa Al-Solami

“…Lastly, the security strength of obtained S-box is further elevated through the action of proposed algebraic group structure. The standard set of performance parameters such as nonlinearity, strict avalanche criterion, bits independent criterion, differential uniformity, and linear approximation probability is quantified to assess the security and robustness of proposed S-box. …”

Characterization of Complex Image Spatial Structures Based on Symmetrical Weibull Distribution Model for Texture Pattern Classification by Jinping Liu, Jiezhou He, Zhaohui Tang, Pengfei Xu, Wuxia Zhang, Weihua Gui

“…Visually, the visual appearance of the complex spatial structure (CSS) of texture pattern (TP) generally depends on the random organization (or layout) of local homogeneous fragments (LHFs) in the imaged surface. …”

Beyond variance: simple random distributions are not a good proxy for intraspecific variability in systems with environmental structure by Girard-Tercieux, Camille, Vieilledent, Ghislain, Clark, Adam, Clark, James S., Courbaud, Benoit, Fortunel, Claire, Kunstler, Georges, Pélissier, Raphaël, Rüger, Nadja, Maréchaux, Isabelle

“…Communities simulated with unstructured IV never reached the community diversity and composition of those where all the variation was explained and structured (perfect knowledge model). This highlights that incorporating unstructured IV (i.e. a random noise) to account for unexplained (but structured) variation can lead to incorrect simulations of community dynamics. …”

Preventing Escape of Non-Native Species from Aquaculture Facilities in Florida, Part 3: Structural Strategies by Quenton M. Tuckett, Carlos V. Martinez, Jared L. Ritch, Katelyn M. Lawson, Jeffery E. Hill

“… Non-native species sometimes escape from aquaculture facilities, but producers can prevent these potentially harmful escapes by placing barriers like screens, covers, control structures, and ponds at vulnerable points. Aquaculture producers use these structures to prevent release of non-native species in compliance with Florida Aquaculture Best Management Practices. …”
