The Lefschetz zeta function associated to a continuous self-map f of a compact manifold is a rational function P/Q. According to the parity of the degrees of the polinomials P and Q, we analize when ...

A strategy of multiscale collaborative design which combines high-entropy effect, dual-phase composition, highly porous structure and foam-gelcasting-freeze drying technique leads to uniform element ...

The scanning-tunneling microscope (STM), which is used to study changes in the shape of a single molecule at the atomic scale, impacts the ability of that molecule to make these changes, researchers ...
