Where does atomic photoionization begin?
We perform a time-delay analysis of of strong field ionization of atomic hydrogen in the tunnelling regime. We obtain the values of the time delay from the quantum-mechanical calculation involving solution of the time-dependent Schrödinger equation, and use these values as parameters defining corresponding classical trajectories. We demonstrate that almost all the classical trajectories, define...
متن کاملWhere Does The Dark Matter Begin?
While there is convincing evidence that the central regions (r ≪ Re) of earlytype galaxies are dominated by stars and that the outer regions (r ≫ Re) are dominated by dark matter, the structure of early-type galaxies in the transition region (a few effective radii Re) between the stars and the dark matter is unclear both locally and in gravitational lenses. Understanding the structure of galaxi...
متن کاملWhere does architecture end and technology begin?
Over the last several years, the software architecture community has reached significant consensus about what we mean by architecture; what differentiates architecture from design; the role that architecture plays in the development of products and product lines; and how we can analyze architectures to anticipate development problems. One area where some confusion remains is differentiating an ...
متن کاملDoes the crayfish tail fan sense chemicals
Crayfish depend on sensilla, small cuticular structures occurring all over their bodies to acquire information about their outside environment. Sensilla contain sensory neurons that are either mechanoreceptive or chemoreceptive. The tail fan of crayfish houses numerous sensilla that contain mechanoreceptor neurons and their activation by animals approaching from behind elicits a tail-flip escap...
