We summarize recent contributions in the broad area of age of information (AoI). In
particular, we describe the current state of the art in the design and optimization of low …

We consider a cache updating system with a source, a cache and a user. There are n files.
The source keeps the freshest version of the files which are updated with known rates λ i …

We consider a resource-constrained updater, such as Google Scholar, which wishes to
update the citation records of a group of researchers, who have different mean citation rates …

We consider an information update system where an information receiver requests updates
from an information provider in order to minimize its age of information. The updates are …

We consider an information updating system where a source produces updates as
requested by a transmitter. The transmitter further processes these updates in order to …

The problem of goal-oriented semantic filtering and timely source coding in multiuser
communication systems is considered here. We study a distributed monitoring system in …

An information source generates independent and identically distributed status update
messages from an observed random phenomenon which takes n distinct values based on a …

We study age of information in a multiple source-multiple destination setting with a focus on
its scaling in large wireless networks. There are n nodes uniformly and independently …

We consider a communication system in which the destination receives status updates from
an information source that observes a physical process. The transmitter performs semantics …

This paper lists in alphabetical order by the name of the first author, 745 papers dealing with
fractional programming and its applications. This covers mainly the period 2005-2012 but it …
