Life 10 that are fixed in one place or that move very slowly, such as trees or jellyfish, tend to have a different kind of symmetry, similar to that of a cone (球果)— they produce similar reflections in any mirror passing through their central axis....
The proper motion is aligned with the axis of symmetry of the inner Crab nebula and, presumably, with the pulsar spin axis.doi:10.48550/arXiv.astro-ph/9811379PATRIZIA A. CARAVEORoberto MignaniarXivPhysics
With a position angle of 292 +/- 10 deg, the proper motion vector appears aligned with the axis of symmetry of the inner Crab nebula, as defined by the direction of the X-ray jet observed by ROSAT. Indeed, if the neutron star rotation is to be held responsible both for the X-ray ...

Perturbation of symmetry of cell division results in dysmorphia even tumors1,2. The symmetry of cell division is determined by the division axis relative to the cell polarity axis. In principle, the cell division axis is ruled by mitotic spindle orientation, which is mainly mediated by LGN-NuMA...
symmetry ( 对称 ) and order. There are lots of symmetric buildings along the axis. The Forbidden City is the most well-known. ‘The unique and magnificent spatial order of Beijing was generated by this central axis,’ said an architect. 相关知识点: 试题来源: 解析 1. (f)amous 2. ...
These profiles are coupled with prior measurements along the line of sight and the surface-brightness profile, and fit all together with self-consistent models specifically constructed to describe quasi-relaxed stellar systems with realistic differential rotation, axisymmetry and pressure anisotropy. The ...
aUnder the assumption of local minima for the pressure on the axis of symmetry with respect to the radial variations we show that the solution blows-up in finite time. 在之下地方极小值的做法为压力在对称轴关于辐形变异我们表示,解答在有限时间鼓起。[translate] ...
(Fig.6). A pri-miR contains two ss–dsRNA junctions at each end of the stem, and Drosha must bind the basal junction to make the correct cut. The inherent structural symmetry near the branch points poses a unique challenge for MP to distinguish the basal junction from the apical junction...
study, we consider the two sets of operators, i.e., one set consisting of the new spin and OAM operators and another set consisting of the Dirac spin and OAM operators, because only two spin operators are derived from the parity-extended Poincaré group, i.e., the space-time symmetry28...
