From their observations, the scientists find that the matter ejected by the explosion shows significant peripheral asymmetry but a nearly spherical interior, most likely implying that the explosion finally propagates at supersonic speed.
Chinese Tech Incubator Vs 'Information Asymmetry ' In Short-Seller Attacks.
Clashes of arms magnify asymmetries as nothing else does.
But the asymmetry in each of the cases here – the US and Soviet submarine forces and the Israeli and Lebanese armies – is more profound than a mere difference in the quality of weapons and training.
Given the common presentation of limb asymmetry, these panelists describe how leg length discrepancy affects orthotic prescription.
If one scans the literature it readily becomes obvious that leg length discrepancy /asymmetry is a common finding.
The overthrow of the book would have happened long ago but for the great user asymmetry inherent in all media.
Physicists had suspected they had some time asymmetry, and now find first solid proof of it.

In science:

The main influence on the shear modulus is due to relaxation in potentials with asymmetries smaller than kB T ; for larger asymmetries the influence decreases rapidly because of the square of the hyperbolic cosine in the denominator.
Energy landscape - a key concept for the dynamics of glasses and liquids
In a Gedankenexperiment, let the thermally equilibrated relaxation center return from the actual asymmetry ∆ + γ ǫ in the strained state to its original asymmetry ∆, say by appropriate jumps in the surroundings which change the local strain at the center.
Energy landscape - a key concept for the dynamics of glasses and liquids
The importance of investigating neutrino asymmetries goes from astrophysics to cosmology where the direction of the rotation of the universe can be determined by this asymmetry.
Neutrino asymmetry in general relativistic rotating radiative stars
Therefore, the reason of time-asymmetry is the asymmetry of the universe, namely, a global reason.
The cosmological origin of time-asymmetry
As we have seen, the time-asymmetry of the global energy flux is a consequence of the time-asymmetry of the geometry of the universe.
The cosmological origin of time-asymmetry
In this way, the global time-asymmetry of the universe defines the local time-asymmetry in each one of its points.
The cosmological origin of time-asymmetry
The quantum process tomography results indicate a large asymmetry in the process and also the required operation to correct for this asymmetry.
Diagnosis, prescription and prognosis of a Bell-state filter by quantum process tomography
We just show the numerical results in Figure 3, where we plot the CP asymmetry divided by sin(φ′ − 2δ), to show better the connection between the sign of the CP asymmetry and the low energy CP violation.

The asymmetry in these rˆoles is, as Deutsch and Hayden point out, analogous to the asymmetry in the rˆoles of the key and cyphertext in classical encryption based on a shared secret random string11 .
Nonlocality and information flow: The approach of Deutsch and Hayden
The latter is governed by the difference in topology of the free energy surface due to the joint effect of the asymmetry in initial state energy about OP90, which almost disappears at L > 16 (Fig. 2(e)), and the asymmetry by a finite displacement in OP theta position of the watershed from 90◦ .
