Menstruation at the Age of 3½ Years

Pulsar Death at an Advanced Age

I summarize the theory of acceleration of non-neutral particle beams by starvation electric fields along the polar magnetic field lines of rotation powered pulsars, including the effect of dragging of inertial frames which dominates the acceleration of a space charge limited beam. I apply these results to a new calculation of the radio pulsar death line, under the hypotheses that pulsar “death”...

LTE-Advanced 8×8 MIMO Measurements in an Indoor Scenario

The potential link performance gains obtained with up to 8×8 MIMO transmissions as standardized in 3GPP LTE Release 10 have been evaluated in an indoor measurement campaign using a testbed implementation. For well-separated antennas, the results show increasing downlink throughput when increasing the number of transmit and receive antennas, up to a median throughput of 335 Mbps for an 8×8 MIMO ...
