Automatic subscriptions in publish-subscribe systems
In this paper, we describe how to automate the process of subscribing to complex publish-subscribe systems. We present a proof-of-concept prototype, in which we analyze Web browsing history to generate zero-click subscriptions to Web feeds and video news stories. Our experience so far indicates that user attention data is a promising source of data for automating the subscription process
Reconstructing weak values without weak measurements
I propose a scheme for reconstructing the weak value of an observable without
the need for weak measurements. The post-selection in weak measurements is
replaced by an initial projector measurement. The observable can be measured
using any form of interaction, including projective measurements. The
reconstruction is effected by measuring the change in the expectation value of
the observable due to the projector measurement. The weak value may take
nonclassical values if the projector measurement disturbs the expectation value
of the observable.Comment: 6 pages. Accepted in Phys. Lett.
