Unidirectional acoustic metamaterials based on nonadiabatic holonomic quantum transformations
...
Published in Science China Physics, Mechanics & Astronomy
Nonadiabatic holonomic quantum transformations (NHQTs) have attracted wide attention and have been applied in many aspects of quantum computation, whereas related research is usually limited to the field of quantum physics. Here we bring NHQTs into constructing a unidirectional acoustic metamaterial (UDAM) for shaping classical beams. The UDAM is m...
Spin current Kondo effect in frustrated Kondo systems
Published in Science China Physics, Mechanics & Astronomy
Magnetic frustrations can enhance quantum fluctuations in spin systems and lead to exotic topological insulating states. When coupled to mobile electrons, they may give rise to unusual non-Fermi liquid or metallic spin liquid states whose nature has not been well explored. Here, we propose a spin current Kondo mechanism underlying a series of non-F...
Event-triggered robust MPC of nonlinear cyber-physical systems against DoS attacks
Published in Science China Information Sciences
This paper proposes an event-triggered robust nonlinear model predictive control (NMPC) framework for cyber-physical systems (CPS) in the presence of denial-of-service (DoS) attacks and additive disturbances. In the framework, a new robustness constraint is introduced to the NMPC optimization problem in order to deal with additive disturbances, and...
Learning practically feasible policies for online 3D bin packing
Published in Science China Information Sciences
We tackle the online 3D bin packing problem (3D-BPP), a challenging yet practically useful variant of the classical bin packing problem. In this problem, the items are delivered to the agent without informing the full sequence information. The agent must directly pack these items into the target bin stably without changing their arrival order, and ...
Label propagation dictionary learning based process monitoring method for industrial process with between-mode similarit...
Published in Science China Information Sciences
With the development of the industrial cyber-physical systems, a small amount of labeled data and a large amount of unlabeled data are collected from the industrial process. Due to the variation of internal operation conditions and external environment, there is a between-mode similarity between data samples. The scarcity of labeled data and the ex...
Reinforcement learning based energy efficient robot relay for unmanned aerial vehicles against smart jamming
Published in Science China Information Sciences
Unmanned aerial vehicles (UAVs) with limited energy resources, severe path loss, and shadowing to the ground base stations are vulnerable to smart jammers that aim to degrade the UAV communication performance and exhaust the UAV energy. The UAV anti-jamming communication performance, such as the outage probability, degrades if the robot relay is no...
Survey on rain removal from videos or a single image
Published in Science China Information Sciences
Rain can cause performance degradation of outdoor computer vision tasks. Thus, the exploration of rain removal from videos or a single image has drawn considerable attention in the field of image processing. Recently, various deraining methodologies have been proposed. However, no comprehensive survey work has yet been conducted to summarize existi...
Wireless/wired integrated transmission for industrial cyber-physical systems: risk-sensitive co-design of 5G and TSN pro...
Published in Science China Information Sciences
The growing popularity of intelligent manufacturing is driven by deterministic transmission demands of applications in industrial cyber-physical systems (ICPS). However, the ossified shortages of industrial wireless communication such as diverse quality of service (QoS) and complex signaling processes incur a severe long tail of transmission delay ...
Three-dimensional ultrasound subwavelength arbitrary focusing with broadband sparse metalens
Published in Science China Physics, Mechanics & Astronomy
Ultrasound focusing in three-dimensional (3D) space is of crucial and enduring significance in a variety of biomedical and industrial applications. Conventional ultrasound focusing based on active phase array or passive geometry of bulky size is unable to realize the 3D arbitrary focusing with subwavelength resolution. Acoustic metamaterial of comp...
