A biologically-inspired approach to designing wireless sensor networks [PDF]

, 2005
In this paper, we contend that there are significant advantages in treating some classes of sensor networks as biological-like systems-- both in structural design characteristics and in operational processes.

Real-time information processing of environmental sensor network data using Bayesian Gaussian processes

, 2012
In this article, we consider the problem faced by a sensor network operator who must infer, in real time, the value of some environmental parameter that is being monitored at discrete points in space and time by a sensor network.

Chemotherapy for Spinal Cord Intramedullary Pediatric Low‐Grade Glioma—A Systematic Literature Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.
