| Supernode transformation has been proposed to reduce the communication startup cost by grouping a number of iterations in a perfectly nested loop with uniform dependencies as a supern-ode which is assigned to a processor as a single unit. A supernode transformation is speciied by n families of hyperplanes which slice the iteration space into parallelepiped supernodes, the grain size of a supe...

A thermodynamic criterion is developed to define the finest grain size that can be achieved during phase transformation, as a function of the driving force, interfacial energies and the parent phase grain size. It is found that at large undercoolings below the equilibrium temperature, the grain size achieved in practice is far greater than predicted theoretically. This is because of the heat of...

Grain shape and size are involved in the main components of the domestication syndrome in cereals. Wheat grain shape has been dramatically altered at each stage of the domestication of tetraploid wheat and through common wheat speciation. To elucidate the evolutionary change of wheat grain shape, principal component (PC) analysis of grain shape-related traits was first conducted using wild and ...

Of special interest within the field of avalanche research and avalanche warning are properties related to snow grain type and snow grain size at the surface. In continental and intermountain avalanche climates weak layers or interfaces are the main cause of avalanches. Knowledge about such weak layers helps to increase the precision of avalanche forecasting. Some of these potential weak layers...

Shape is an important morphological characteristic both in animals and plants. In the present study, we examined a method for predicting biological contour shapes based on genome-wide marker polymorphisms. The method is expected to contribute to the acceleration of genetic improvement of biological shape via genomic selection. Grain shape variation observed in rice (Oryza sativa L.) germplasms ...

The grain size is one of the complex trait of rice yield controlled by a plethora of interaction of several genes in different pathways. The present study was undertaken to investigate the influence of seven known grain size regulating genes: DEP1, GS7, GS3, GW8, GL7, GS5 and GW2. A wide phenotypic variation for grain length, grain width and grain length-width ratio were observed in 89 germplas...

the purpose of this study was to investigate the effect of heat treatment including solution treatment and aging on the microstructure of cast nickel-based in100 superalloy including size, volume fraction and morphology of primary γ' and different kinds of carbides. for this purpose, different solution heat treatment cycles and a constant aging cycle were implemented on cast ingot samples and t...
