Behavior and olfactory responses of grasshopper hatchlings, Melanoplus sanguinipes (F.), to odours from plant foliage and volatile compounds were tested using a
Assembly sequence planning will be more difficult due to the in-creasing complexity of products.An integrated approach to assembly sequence planning of complex
This paper discusses pseudo-randomness of a periodic sequence, named the fourth class of GSS sequence. We get the ollowing results: ① Its least period always r
We introduce a divergence-free Hardy space H1z,div(RN+, RN) and prove its divergence-free atomic decomposition. We also characterize its dual space and establis
Poisson algebras are fundamental algebraic structures in physics and symplectic geometry. However, the structure theory of Poisson algebras has not been well de
We gave a complete list of totally geodesic submanifolds of maximal rank in symmetric spaces of noncompact type. The compact cases can be obtained by the dualit
