Traditionally, this is provided by maritime satellites. Besides, shore and island-based base stations (BSs) can be built to extend the coverage of terrestrial networks providing the fourth-generation (4G) or even the fifth-generation (5G) services. Unmanned aerial vehicles (UAVs)-aided and ship-borne BSs can also be exploited to serve as relaying nodes in maritime mesh/ad-hoc networks. Despite all these approaches, there are still open issues towards the establishment of an agile maritime communication network (MCN). Different from terrestrial communications for urban or suburban coverage, the MCN faces several challenges due to the complicated electromagnetic propagation environment, the limited geometrically available BS sites, and rigorous service demands from mission-critical applications. To address all these challenges, conventional communications and networking theories and methods need to be tailored for maritime application scenarios or new ones should be explored. The goal of this feature topic is to present the state-of-the-art original research, and the latest advances and innovations in key theories, technologies, and innovative applications for agile MCNs, as well as identify emerging research topics and point out the future research directions. Extended versions of papers published in conferences, symposiums, or workshop proceedings are encouraged for consideration.展开更多

In this experiment, we used mouse oocytectomized complexes (OOX), which were incapable of CEEF production, to assess the secretion of CEEF by evacuated zona, oocytes of different quality and somatic cells in the porcine follicles. The results showed that: (i) Evacuated zonae from both porcine and mouse oocytes did not produce CEEF. (ii) Porcine oocytes of A, B and C types from 3-6 mm follicles were not significantly different in both production and activity of CEEF. (iii) Both porcine OOX from 3-6 mm follicles and granulose cells from 【 1 mm follicles secreted CEEF in a large quantity, independent of gonadotro-pins; mural granulose cells from 3-6 mm follicles, however, produced neglectable amount of CEEF. (iv) The follicular fluid from 3-6 mm porcine follicles contained CEEF activity that was concentration-dependent,展开更多
