—In this paper we focus on the analysis of the end-to-end outage probability of hybrid automatic repeat request (HARQ) in a multi-hop, block-fading channel. First, we use a Markov chain to model the multi-hop system with truncated HARQ type-I (HARQ-I) and derive closed-form expressions for the outage probability and throughput; we also obtain lower and(More)
Changes in environmental conditions may lead to modifications in structural development of plant root. Effects of supplementary irrigation and soil depths (0–90 cm) on anatomical changes in xylem were investigated in rain-fed Vitis vinifera L. cv. Yaghooti-Syah Shiraz. Irrigated and control roots were prepared according to routine histological procedure.(More)
