A review on kinetic models of dynamic recrystallization for magnesium alloys

Journal of Materials Research and Technology
Mg alloys are the lightest metallic structural material with tremendous application value. Dynamic recrystallization (DRX) is the most important grain refining and texture weakening mechanism for Mg alloys.

A comprehensive simulation analysis of LTE Discontinuous Reception (DRX)

Computer Networks, 2014
In an LTE cell, Discontinuous Reception (DRX) allows the central base station to configure User Equipments for periodic wake/sleep cycles, so as to save energy. DRX operations depend on several parameters, which can be tuned to achieve optimal performance with different traffic profiles (i.e., CBR vs. bursty, periodic vs. sporadic, etc.).
