Anti-CREM polyclonal antibody

To study the activated dynamics of mean-field glasses, which takes place on times of order exp(N), where N is the system size, we introduce a new model, the correlated random energy model (CREM), that allows for a smooth interpolation between the REM and the p-spin models. We study numerically and analytically the CREM in the intermediate regime between REM and p-spin. We fully characterize its energy landscape, which is like a golf course but, at variance with the REM, has metabasins (or holes) containing several configurations. We find that an effective description for the dynamics, in terms of traps, emerges, provided that one identifies metabasins in the CREM with configurations in the trap model.

The effect of application of the out-of-phase electromagnetic field in HDC on the process and the metallurgical quality of 7075 alloy ingots was investigated in detail. The results show that when out-of-phase electromagnetic field was applied, the effect of gravity on the HDC casting process was eliminated effectively, the temperature distribution in the pool became more uniform, the cooling difference between upper and bottom surface and depth of sump were decreased, the sump shape was changed to be more symmetric about geometrical center of the mold, the thickness of segregation layer decreased and the surface quality and the microstructures of the ingots were improved, the area of feathery grains decreased and the area of equiaxed grains increased, the equiaxed grains were refined and the floating grains eliminated so that the quality of the ingots was improved.
