Privacy has become an emerging challenge in both information theory and computer science due to massive (centralized) collection of user data. In this article, we overview privacy-preserving mechanisms and metrics from the lenses of information theory, and unify different privacy metrics, including f-divergences, Rényi divergences, and differential privacy (...

Group testing is the technique of pooling together diagnostic samples in order to increase the efficiency of medical testing. Traditionally, works in group testing assume that the infections are i.i.d. However, contagious diseases like COVID-19 are governed by community spread and hence the infections are correlated. This survey presents an overview of recen...

The initial vision of cellular communications was to deliver ubiquitous voice communications to anyone anywhere. In a simplified view, 1G delivered voice services for business customers, and only 2G for consumers. Next, this also initiated the appetite for cellular data, for which 3G was designed. However, Blackberry delivered business smartphones, and 4G ma...

It is already winter in the Northern Hemisphere, and I cannot believe how fast this year is going by. This is my second column, which traditionally congratulates on awards and highlights new initiatives.

X-ray fluorescence (XRF) analysis of art objects has rapidly gained popularity since the late 2000s due to its increased accessibility to scientists. This introduced an imaging component whereby the XRF image volume provides clues as to which chemical elements are present and where they are located spatially in the object. However, as is the nature of collec...
