We have studied morphological evolution in clusters simulated in the adiabatic limit and with radiative cooling. Cluster morphology in the redshift range, 0 < z < 0.5, is quantified by multiplicity and ellipticity. In terms of ellipticity, our result indicates slow evolution in cluster shapes compared to those observed in the X-ray and optical wavelengths. The result is consistent with Floor, M...

We measure the morphology–density relation of galaxies at z=1 across the full three orders of magnitude in projected galaxy density available in low–redshift studies. Our study adopts techniques that are comparable with those applied at lower redshifts, allowing a direct investigation of how the morphological segregation of galaxies has evolved over the last 8 Gyr. Although the morphology–densi...

Functional coupling, where a single morphological trait performs multiple functions, is a universal feature of organismal design. Theory suggests that functional coupling may constrain the rate of phenotypic evolution, yet empirical tests of this hypothesis are rare. In fish, the evolutionary transition from guarding the eggs on a sandy/rocky substrate (i.e. substrate guarding) to mouthbrooding...

The NbSe2 nanoplates with novel hexagonal morphology have been obtained via solid-state assembly of NbSe2 ultrathin nanosheets, which were prepared by a simple calcination process using micro-sized Nb and Se powders as the precursors. The influence of high-temperature annealing upon morphology of single-crystal NbSe2 was investigated. On the basis of experimental results of different temperatur...
