With the rapid increasing of maritime activities, maritime wireless networks(MWNs) with high reliability, high energy efficiency, and low delay are required. However, the centralized networking with fixed resource scheduling is not suitable for MWNs due to the special environment. In this paper,we introduce the collaborative relay communication in distributed MWNs to improve the link reliability, and propose an orthogonal time-frequency resource block reservation based multiple access(RRMA) scheme for both one-hop direct link and two-hop collaborative relay link to reduce the interference. To further improve the network performance, we formulate an energy efficiency(EE) maximization resource allocation problem and solve it by an iterative algorithm based on the Dinkelbach method. Finally, numerical results are provided to investigate the proposed RRMA scheme and resource allocation algorithm, showing that the low outage probability and transmission delay can be attained by the proposed RRMA scheme. Moreover,the proposed resource allocation algorithm is capable of achieving high EE in distributed MWNs.

Non-orthogonal multiple access(NOMA)based fog radio access networks(F-RANs)offer high spectrum efficiency,ultra-low delay,and huge network throughput,and this is made possible by edge computing and communication functions of the fog access points(F-APs).Meanwhile,caching-enabled F-APs are responsible for edge caching and delivery of a large volume of multimedia files during the caching phase,which facilitates further reduction in the transmission energy and *** need of the prevailing situation in industry is that in NOMA-based F-RANs,energy-efficient resource allocation,which consists of cache placement(CP)and radio resource allocation(RRA),is crucial for network performance *** this end,in this paper,we first characterize an NOMA-based F-RAN in which F-APs of caching capabilities underlaid with the radio remote heads serve user equipments via the NOMA ***,we formulate a resource allocation problem for maximizing the defined performance indicator,namely network profit,which takes caching cost,revenue,and energy efficiency into *** NP-hard problem is decomposed into two sub-problems,namely the CP sub-problem and RRA ***,we propose an iterative method and a Stackelberg game based method to solve them,and numerical results show that the proposed solution can significantly improve network profit compared to some existing schemes in NOMA-based F-RANs.

As a subset of the proteome, peptidomics is the best tool to analyze peptides in different food matrices. Milk peptides are produced by protease hydrolysis in the mammary gland, which plays an important role in the growth and development of infants. However, methods of probing endogenous peptides are limited because the concentration of peptides is low, the peptides are easily lost during extraction/enrichment, and database searches are complicated. Based on the peptidomics analysis process, this paper reviews the research progress and applications of endogenous peptides with a focus on extraction, fractionation, identification, and bioinformatics analysis. Additionally, in-depth analysis of endogenous peptides in milk and milk-related products using joint strategies (a combined analysis of proteome/peptidomics/metabolomic approaches) was also introduced. New methodologies are provided to study peptides through bioinformatics and tracking the release of bioactive peptides from various milk sources by in vitro digestion models, which can better track the utilization of endogenous peptides in vivo. Challenges and future perspectives are also discussed, with a goal of exploring more bioactive peptides in milk and dairy products as well as simulating human milk in formula milk powder in the future.

在水下近场爆炸载荷的研究中,高速破片侵彻问题异常复杂,由于爆炸实验的不可重复性和危险性,如何运用数值仿真较好地模拟侵彻问题一直备受关注。运用耦合的欧拉-拉格朗日(CEL)算法,开展了高速破片侵彻液舱实验模型的仿真,验证了CEL算法在处理侵彻问题的可靠性和准确性;在此基础上,开展了不同破片速度和液体装载量对穿透压力和空穴演化的影响研究。结果表明:破片速度衰减规律、空穴演化以及侵彻过程中压力时历曲线与实验值基本一致;弹道远离液面时,液体装载量并不影响速度衰减规律;随着与自由液面距离减小,近自由液面入射弹道非对称性差异可由20%增加到48%;破片初始速度增加,前置隔板的变形略有增加,后置隔板的变形呈非线性增长。
