All field emission experiments are noisy, … are any meaningful?

Avascular Necrosis of the Femoral Head: Are Any Genes Involved?

Avascular necrosis of the femoral head (ANFH) is a pathologic process that results from interruption of blood supply to the femur bone resulting in the death of bone cells and collapse of the femoral head. Nontraumatic ANFH continuesto be a significant challenge to orthopedic surgeons. While the exact mechanisms remain elusive, many new insights have emerged from research in the last decade tha...

Finite groups all of whose proper centralizers are cyclic

‎A finite group $G$ is called a $CC$-group ($Gin CC$) if the centralizer of each noncentral element of $G$ is cyclic‎. ‎In this article we determine all finite $CC$-groups.

Are all noisy quantum states obtained from pure ones?

We ask what type of mixed quantum states can arise when a number of separated parties start by sharing a pure quantum state and then this pure state becomes contaminated by noise. We show that not all mixed states arise in this way. This is even the case if the separated parties actively try to degrade their initial pure state by arbitrary local actions and classical communication.

All of Us Are Smarter than Any of Us: Nondeterministic Wait-Free Hierarchies Are Not Robust

A wait-free hierarchy Herlihy91, Jayanti93] classiies object types on the basis of their strength in supporting wait-free implementations of other types. Such a hierarchy is robust if it is impossible to implement objects of types that it classiies as \strong" by combining objects of types that it classiies as \weak". We prove that, if nondeterministic types are allowed, the only wait-free hier...
