Metaheuristic Hybrids

Over the last years, so-called hybrid optimization approaches have become increasingly popular for addressing hard optimization problems. In fact, when looking at leading applications of metaheuristics for complex real-world scenarios, many if not most of them do not purely adhere to one specific classical metaheuristic model but rather combine different algorithmic techniques. Concepts from di...

Interspecific Hybrids

The regulation of gene expression is essential for organismal form, function, and fitness. Complex organismal development from zygote to adult requires finely tuned expression of genes in space, time, and abundance. Proper expression of genes is also required for most other aspects of physiology and function. Even minor changes in gene expression have the potential to significantly impact pheno...

Sturgeon Species and Hybrids: Can Hybrids Produce Caviar?

Heavy Hybrids from NRQCD

We present a quenched lattice calculation for the lowest lying bb̄g-hybrid states in the framework of NRQCD using the leading order Hamiltonian up to O(mv). We demonstrate the existence of a nearly degenerate rotational band of states with an excitation energy approximately 1.6 GeV above the Υ ground state. This lies around the BB̄ J threshold but well above the BB̄-threshold. Therefore a heavy hy...

Selecting Corn Hybrids

Corn is physiologically mature when kernels reach maximum dry weight and are safe from frost. All milky fluid disappears from the kernel, and the black layer, a dark layer of cells, forms near the tip of mature kernels. Most hybrids adapted to Wisconsin reach this stage when kernel moisture decreases to 30–32%, but it may not occur until moisture content decreases to 28% for some early hybrids....
