2Ambient Backscatter Communications over NOMA Downlink Channels显示文摘In this paper,we investigate the performance of commensal ambient backscatter communications(AmBC)that ride on a non-ortho go nal multiple access(NOMA)downlink transmission,in which a backscatter device(BD)splits part of its received signals from the base station(BS)for energy harvesting,and backscatters the remaining received signals to transmit information to a cellular user.Specifically,under the power consumption constraint at BD and the peak transmit power constraint at BS,we derive the optimal reflection coefficient at BD,the optimal total transmit power at BS,and the optimal power allocation at BS for each transmission block to maximize the ergodic capacity of the ambient backscatter transmission on the premise of preserving the outage performance of the NOMA downlink transmission.Furthermore,we consider a scenario where the BS is restricted by a maximum allowed average transmit power and the reflection coefficient at BD is fixed due to BD’s low-complexity nature.An algorithm is developed to determine the optimal total transmit power and power allocation at BS for this scenario.Also,a low-complexity algorithm is proposed for this scenario to reduce the computational complexity and the signaling overheads.Finally,the performance of the derived solutions are studied and compared via numerical simulations.Weiyu Chen Haiyang Ding Shilian Wang Daniel Benevides daCosta Fengkui Gong Pedro Henrique Juliano Nardelli 2020China Communications2020,17,6:4
3Factors affecting the direct mineralization of CO_2 with olivine显示文摘Olivine, one of the most abundant minerals existing in nature, is explored as a CO2 carbonation agent for direct carbonation of CO2 in flue gas. Olivine based CO2 capture is thermodynamically favorable and can form a stable carbonate for long-term storage. Experimental results have shown that water vapor plays an important role in improving CO2 carbonation rate and capacities. Other operation conditions including reaction temperature, initial CO2 concentration, residence time corresponding to the flow rate of CO2 gas stream, and water vapor concentration also considerably affect the performance of the technology.Soonchul Kwon Maohong Fan Herbert F.

4Concise review on short bowel syndrome: Etiology, pathophysiology, and management显示文摘Adults have approximately 20 feet of small intestine,which is the primary site for absorbing essential nutrients and water.Resection of the intestine for any medical reason may result in short bowel syndrome(SBS),leading to loss of major absorptive surface area and resulting in various malabsorption and motility disorders.The mainstay of treatment is personalized close dietary management.Here we present SBS with its pathophysiology and different nutritional management options available.The central perspective of this paper is to provide a concise review of SBS and the treatment options available,along with how proper nutrition can solve major dietary issues in SBS and help patients recover faster.Saraswathi Lakkasani Deeksha Seth Imran Khokhar Masara Touza Theodore Jr Dacosta 2022World Journal of Clinical Cases2022,10,31:2
