Local Thermal Equilibrium in Quantum Field Theory on Flat and Curved Spacetimes [PDF]
, 2010 The existence of local thermal equilibrium (LTE) states for quantum field theory in the sense of Buchholz, Ojima and Roos is discussed in a model-independent setting.

A new Power Efficient – Delay Aware Downlink Algorithm for 3GPP LTE Cellular Networks [PDF]
Port Said Engineering Research Journal, 2020 Scheduling in downlink transmission in long term evolution (LTE) is a very important process accomplished in the eNodeB. Through the scheduling process, the network dynamically allocates the available radio Resource Blocks (RBs) to users based on the ...

Iron abundances from optical Fe III absorption lines in B-type stellar spectra [PDF]
, 2007 The role of optical Fe III absorption lines in B-type stars as iron abundance diagnostics is considered. To date, ultraviolet Fe lines have been widely used in B-type stars, although line blending can severely hinder their diagnostic power. Using optical

Definition and Validation of an Exposure Measurement Method for a Typical Load of a Base Station. [PDF]
BioelectromagneticsABSTRACT In the context of risk communication in mobile radio, a discussion has emerged whether exposure at common load of a base station should be presented in addition to the theoretical maximum, especially with 5G massive‐MIMO. However, a reproducible measurement method for instantaneous exposure independent of the utilization of the cell has yet to

Vulnerability of LTE to Hostile Interference
, 2014 LTE is well on its way to becoming the primary cellular standard, due to its performance and low cost. Over the next decade we will become dependent on LTE, which is why we must ensure it is secure and available when we need it.
