| 1 | Multi-agent reinforcement learning for edge information sharing in vehicular networks显示文摘To guarantee the heterogeneous delay requirements of the diverse vehicular services,it is necessary to design a full cooperative policy for both Vehicle to Infrastructure(V2I)and Vehicle to Vehicle(V2V)links.This paper investigates the reduction of the delay in edge information sharing for V2V links while satisfying the delay requirements of the V2I links.Specifically,a mean delay minimization problem and a maximum individual delay minimization problem are formulated to improve the global network performance and ensure the fairness of a single user,respectively.A multi-agent reinforcement learning framework is designed to solve these two problems,where a new reward function is proposed to evaluate the utilities of the two optimization objectives in a unified framework.Thereafter,a proximal policy optimization approach is proposed to enable each V2V user to learn its policy using the shared global network reward.The effectiveness of the proposed approach is finally validated by comparing the obtained results with those of the other baseline approaches through extensive simulation experiments. | Ruyan Wang Xue Jiang Yujie Zhou Zhidu Li Dapeng Wu Tong Tang Alexander Fedotov Vladimir Badenko | 2022 | Digital Communications and Networks2022，8，3： | 3 |
| 2 | Analytical solution of axisymmetric contact problem about indentation of a circular indenter into a soft functionally graded elastic layer显示文摘The paper addresses a contact problem of the theory of elasticity,i.e.,the penetration of a circular indenter with a flat base into a soft functionally graded elastic layer.The elastic properties of a functionally graded layer arbitrarily vary with depth,and the foundation is assumed to be elastic,yet much harder than a layer.Approximated analytical solution is constructed,and it is shown that the solutions are asymptotically exact both for large and small values of characteristic dimensionless geometrical parameter of the problem.Numerical examples are analyzed for the cases of monotonic and nonmonotonic variations of elastic properties.Numerical results for the case of homogeneous layer are compared with the results for nondeformable foundation. | Sergey Volkov Sergey Aizikovich Yue-Sheng Wang Igor Fedotov | 2013 | Acta Mechanica Sinica2013，29，2： | 2 |
| 3 | Renal artery denervation suppresses intractable ventricular arrhythmia in patients with left heart thrombosis显示文摘Transcutaneous renal artery denervation (RND) has beeninitially developed for destruction of efferent nerve fireswith luminal delivery of radiofrequency or ultrasonic energyaiming blood pressure reduction in patients with refractoryhypertension. However, other positive results of RNDwere described afterwards, and they include suppression ofatrial fibrillation and ventricular tachycardia (VT) storm. | Marianna A Vander Petr A Fedotov Tamara A Lyubimtseva Maria A Bortsova Maria Yu Simikova Dmitry S Lebedev Evgeny N Mikhaylov | 2017 | Journal of Geriatric Cardiology2017，14，9： | 2 |
| 4 | 基于平面超材料的Fano谐振可调谐研究显示文摘基于两段相同金属分裂环谐振器构成的单层结构,从理论及实验方面研究了平面超材料的可调谐Fano谐振.实验测量了平面超材料对TE和TM入射波的电磁响应,利用电磁波的入射角度控制Fano谐振的强度,实现了谐振的开关特性,谐振频率红移可达到21%.基于有限元法给出了平面超材料的场分布,强的正常色散表明平面超材料的电磁响应可类比经典电磁诱导透明现象,仿真与实验结果相符合.对称结构超材料Fano谐振的开/关特性为超材料性能的可调谐控制提供了有效途径. | 刘冉 史金辉 E.Plum V.A.
