The vast majority of organic molecules (based on a carbon structure) are not flat, but have a three-dimensional geometry.

105, Issue. 1, p. 98. This is the first full-length book on the major theme of symmetry in graphs. Forming part of algebraic graph theory, this fast-growing field is concerned with the study of highly ...

Symmetry is when one side of a shape is a mirror image of the other side. Lots of buildings and everyday objects use symmetry because it looks appealing to the human eye. But, if you step outside ...

The line is called a line of symmetry. This is sometimes called a 'mirror line' or 'mirror symmetry', because if you put a mirror on the line, the reflection would show the whole shape.

Recently, Prof. Changqing Chen's group at Tsinghua University has developed a theory to characterize the localized static ...

Hydra are small, invertebrate, predatory animals that live in water. They're tubular, radially symmetric and up to 10 mm long ...

Between-limb and between-group differences were explored using mixed models analyses. Results At the time of return to sport after ACLR, athletes still presented significant differences favouring the ...

利用溶质偏析技术设计晶界（GBs）结构是一种定制多晶材料性能的颇具前景的方法。从理论上讲，溶质偏析触发GB相变可为设计界面提供不同的途径，但缺乏对其本征原子性质的理解。
