Soil aggregate stability is an ideal integrative soil quality indicator, but little known about the relevance of such indicator with depth for salt-affected soils. The objective this study was to determine and identify preponderant aggregation factors, both in topsoil subsoil horizons conditions. We conducted field investigations by describing profiles pedological pits collecting samples from d...

The stability region of the two-user degraded Gaussian broadcast channel is characterized in this paper. Two simple power allocation schemes are considered, namely fixed and queue-aware power control. We then provide convexity/concavity conditions for the stability region and we investigate the aggregate stable throughput of the
