  In this study, we consider the design of a radio resource allocation technique for an Orthogonal Frequency Division Multiple Access (OFDMA) based Multiple Input Multiple Output (MIMO) multihop network. To avoid the inter-hop interference, the half-duplex orthogonal relay channel construction method and related multihop transmission scheme are designed. Over Nakagami-m fading channels, we propose a low-complexity resource allocation algorithm using Meijer G-function. And, the long term fairness performance is also investigated. Simulation shows that the proposed analytical algorithm is efficient and with good accuracy to Monte Carlo results. And, simulations also demonstrate that the spatial diversity gain offered by relay antenna array can effectively balance the tradeoff between the fairness performance and the system throughput.

  In the present study, the prevalence of coccidial infection was investigated in dairy cattle and Qinchuan cattle in Shaanxi province, Northwestern China. A total of 228 cattle (83 and 145 for dairy cattle and Qinchuan cattle, respectively) feces samples were collected and examined by flotation technique using saturated saline. Coccidial oocysts were seen in 90 faecal samples with overall prevalence of 34.94% (29/83) and 42.07% (61/145) for dairy cattle and Qinchuan cattle. About 12 Eimeria (namely, E. subspherica, E. ellipsoidalis, E. zurnii, E. pellita, E. bovis, E. canadensis, E. bukidnonensis, E. cylindrica, E. auburnensis, E. brasiliensis, E. bombayansis, E. alabamensis) and one Isospora (only found in Qinchuan cattle) species were identified according to the time of sporulation Coudert’s key and morphological features of sporulated oocysts with the most common species of E. bovis, E. ellipsoidalis, E. zurnii. Total >80 and 90% samples for two breeds were infected with ≥2 species. The coccidial Oocysts Per Gram (OPG) were ranged from 0-2150 with average of 276. These results suggested that integrated strategies should be implemented to prevent and control coccidial infection in cattle in this province.
