This paper studies interference alignment scheme and minimum mean square error (MMSE) improvement in Internet of Things (IoT)-oriented cognitive systems, where IoT devices share the licensed spectrum by cognitive radio in spectrum underlay. Target to manage the inter-tier interference caused by cognitive spectrum sharing as well as ensure an MMSE at receivers, the interference alignment algorit...

The existence (or not) of infinite clusters is explored for two stochastic models intersecting line segments in $d \ge 2$ dimensions. Salient features the phase diagram are established each case. based on site percolation ${\mathbb Z}^d$ with parameter $p\in (0,1]$. For occupied $v$, and $2d$ possible coordinate directions, declare entire segment from $v$ to next given direction be either blue ...

Purpose: Changes in lower extremity alignment in individuals with abnormality of this segments are unclear. The present study aimed to compare lower extremity alignment in subjects with genu valgum and genu varum deformities and healthy subjects  in order to understand the lower extremity alignment changes in this group.  Methods: This was a causal-comparative study. The sample comprised 120 m...
