To assess the genetic diversity among China’s cultivated barley, sequence tagged site (STS) marker analysis was carried out to characterize 109 morphologically distinctive accessions originating from five Chinese eco-geographical zones. Fourteen polymorphic STS markers representing at least one in each chromosome were chosen for the analysis. The 14 STS(More)
BACKGROUND Vascular cognitive impairment-no dementia (VCIND) refers to the early or mild cognitive impairment induced by cerebral vascular injury. Research shows that serum total homocysteine (tHcy) level is an independent risk factor for cerebral vascular disease and may be closely related to cognitive function.Current studies on the tHcy level in VCIND(More)
Smart antennas (SA) has not been applied widely in 3G except TD-SCDMA. As to the application of SA in CDMA system, we argued that people hold certain incorrect view, especial the reciprocity characteristic. Generally, people consider that only using a set of SA, we can simultaneously realize multiple CDMA channels directional transmission on a single(More)
This paper focuses on energy efficiency of device-to-device (D2D) underlay massive multiple-input multiple-output (MIMO) hybrid networks with power beacons (PBs). The D2D transmitters harvest the energy from the signals of dedicated power beacons, but also the ambient radio frequency (RF) interference of cellular users (CUs). The inverse power control(More)
Based on amplify-and-forward network coding (AFNC) protocol, the outage probability and ergodic capacity of two-way network coding opportunistic relaying (TWOR-AFNC) systems are investigated as well as the corresponding closed-form solutions. For the TWOR-AFNC systems, it is investigated under two scenarios, namely, the TWOR-AFNC systems without direct link(More)
