REVOLVING TABLE FOR FLUSHING OPERATIONS.

Do Hardware Cache Flushing Operations Actually Meet Our Expectations?

We investigate how different categories of microarchitectural state on recent ARM and x86 processors can be used for covert timing channels and how effective architecture-provided mechanisms are in closing them. We find that in recent Intel processors there is no effective way for sanitising the state of the branch prediction unit and that, contrary to often held belief, flushing the translatio...

Revolving Door Scenario for

IN THIS ISSUE In this issue of Physics & Society, we continue our series on the risks of nuclear weapons after the Cold War. In their article Illicit Trafficking of Weapons-Usable Nuclear Material: Facts and Uncertainties, Lyudmila Zaitseva and Friedrich Steinhausler have provided us with a very detailed look at what is known about the smuggling of fissile materials. They have also provided a r...

The Revolving Door

The revolving door between the government and the private sector has long been presumed to lead to the capture of regulators by industry interests. A growing body of empirical literature, however, either finds no conclusive evidence of a capture effect or finds evidence of an opposite effect that the revolving door indeed results in more aggressive, not less aggressive, regulatory actions. To a...

Inductive Signals: Revolving vertebrates

An old idea about the relationship between arthropod and vertebrate body plans has been given new life by studies of the signalling genes controlling dorsal and ventral development in Drosophila and Xenopus.
