Android applications are developing rapidly across the mobile ecosystem, but Android
malware is also emerging in an endless stream. Many researchers have studied the …

Random walks are ubiquitous in the sciences, and they are interesting from both theoretical
and practical perspectives. They are one of the most fundamental types of stochastic …

The book systematically introduces theories of frequently-used modern signal processing
methods and technologies, and focuses discussions on stochastic signal, parameter …

Stochastic differential equations are differential equations whose solutions are stochastic
processes. They exhibit appealing mathematical properties that are useful in modeling …

By providing ultra-high transmission data rate, millimeter wave (mmWave) and terahertz
(THz) communications are promising to enable backhaul data transmission in cellular …

Age of information (AoI) was introduced in the early 2010s as a notion to characterize the
freshness of the knowledge a system has about a process observed remotely. AoI was …

In this paper, we provide the theoretical framework for the performance comparison of
reconfigurable intelligent surfaces (RISs) and amplify-and-forward (AF) relaying wireless …

The received signal strength (RSS) based technique is extensively utilized for localization in
the indoor environments. Since the RSS values of neighboring locations may be similar, the …

Automatic weather stations are essential for fine-grained weather forecasting; they can be
built almost anywhere around the world and are much cheaper than radars and satellites …

Diverse cognitive processes set different demands on locally segregated and globally
integrated brain activity. However, it remains an open question how resting brains configure …
