    Security mechanism in access control based on non-cooperative game by Yi-xuan ZHANG, Jing-sha HE, Bin ZHAO

    Published 2014-11-01
    “…Access control technology is an important information security technology to protect the sensitive information and critical resources in computer system and network.But traditional access control methods could only respond to access requests of users passively and can’t meet the changing dynamic network environment.In order to improve the ability to respond to malicious attacks and threats in access control system,a security mechanism is designed,which is suitable for access control,based on non-cooperative game theory in the game.When the subject makes an access request to the object,there will be a non-cooperative game between them to get Nash equilibrium.Then the security mechanism will compare the probabilities in the Nash equilibrium to the setting thresholds to get the conclusion that whether to authorize the subject or not.Experiment proves the effectiveness of the security mechanisms.…”

    Mechanisms of L-citrulline on phosphodiesterase 5 in erectile dysfunction intervention by Abdulhakeem Olarewaju Sulyman, Olawale Moshood Aliyu, Emmanuel Oladipo Ajani, Yusuf Folohunsho Abdulkareem, Isaac Ade Afe, Fathia Oluwakemi Abdulyakeen, Halimat Yusuf Lukman, Saheed Sabiu, Karishma Singh, Kuben Naidoo

    Published 2025-03-01
    “…Kinetic analyses further elucidated citrulline's non-competitive inhibition pattern while molecular dynamics analysis afforded assessment of the binding stability of citrulline with PDE5, both providing insights into its mechanism of action. Citrulline-PDE5 complex had a higher negative binding free energy (-45.06 ± 4.69 kcal/mol) relative to the conventional drug (sildenafil) (-13.86±10.23 kcal/mol). …”

    Mechanical Properties of Plastic Sand Brick Containing Plastic Waste by Kameshwar Sahani, Bhesh Raj Joshi, Kabiraj Khatri, Abiraj Thapa Magar, Sabin Chapagain, Nabanita Karmacharya

    Published 2022-01-01
    “…The purpose of this study was to investigate the environment-friendly potential use of plastic and demonstrate usefulness of plastic sand bricks as alternative structural elements, replacing standard clay brick. The physical and mechanical properties of plastic sand bricks were studied in different plastic sand ratios of 1 : 3, 1 : 4, and 1 : 5 by their weight, using plastic as a binder. …”

    Crowd-based collaboration caching mechanism in smart identifier network by Haifeng LI, Wei QUAN, Nan CHENG, Hongke ZHANG, Xuemin SHEN

    Published 2018-12-01
    “…Smart identifier network (SINET) is an innovative network architecture.Through dynamic collaboration of service resource,function groups and physical components,the network scalability,resource utilization and service quality were effectively improved by SINET,and an effective solution for the development of industrial Internet of things(IoT) could be provided.To promote content delivery in resource-constrained IoT,caching function was introduced in network components by SINET,and the bandwidth waste caused by traffic redundancy in resource-constrained node could be reduced.Therefore,how to efficiently cache content became an important research topic.Based on SINET architecture,a crowd-based collaboration cache (C2Cache) mechanism was proposed in this scheme.According to the actual network topology,the caching function group was dynamically created and optimized by C2Cache,and a function group as crowd minimum unit to execute the maximum benefit cache (MBC) algorithm was defined to maximize the caching space efficiency.With the self-developed emulation system,named EmuStack,the performance of C2Cache was evaluated.The experimental results show that,comparing with LCE,Random,Prob Cache,LCD and Greedy caching mechanisms,the cache hit rate can be improved effectively,then the average access time can be reduced significantly by C2Cache.In the simulated network scenario,the performance increases 15% to 30%.…”
