In this paper, the crack initiation at contact surface of solids is investigated on the basis of the concept of potential energy release rate. The expressions for ...

We prove that the lowest upper bound for the number of isolated zeros of the Abelian integrals associated to quadratic Hamiltonian vector fields having a center and an invariant straight line after ...

Five main classes of clinically applicable virus vector have been engineered over recent years to improve the efficiency and safety of gene delivery. Hybrid vectors that combine the properties of ...
