Ecology and Evolution, Volume 15, Issue 12, December 2025.This study was conducted in an extremely heterogeneous karst forest ecosystem. We found asynchronous changes in taxonomic and functional dissimilarities along the succession pathway and the functional redundancy dominated the functional resemblance structure.

Distribution and Kinematics of Classical Cepheids in the Galactic Outer Ring
Open Astronomy, 2015 The existence of an outer ring in the Galaxy can explain the kinematics of OB associations in the Perseus and Sagittarius stellar-gas complexes. Moreover, it can also explain the orientation of the Carina arm with respect to the major axis of the bar. We

NUCLEAR RINGS IN GALAXIES—A KINEMATIC PERSPECTIVE [PDF]
The Astrophysical Journal, 2011 We combine DensePak integral field unit and TAURUS Fabry-Perot observations of 13 nuclear rings to show an interconnection between the kinematic properties of the rings and their resonant origin. The nuclear rings have regular and symmetric kinematics, and lack strong non-circular motions.

A review of multiscale numerical modeling of rock mechanics and rock engineering
Deep Underground Science and Engineering, Volume 4, Issue 3, Page 382-405, September 2025.Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Influence of Magnetic Fields on the Gas Rotation in the Galaxy NGC 6946
The Astrophysical Journal, 2023 Magnetic fields can play an important role in the energy balance and formation of gas structures in galaxies. However, their dynamical effect on the rotation curve of galaxies is immensely unexplored.
