“…Moreover, the matrix converter can also be utilized for the pulse magnet power supply of ion 2 Complexity accelerators. Bidirectional flowage of energy in the matrix converter can transmit excessive energy of the magnet back to the grid [18][19][20]. e study is a continuation of our preliminary researches [21,22].…”

The current topology schemes of heavy ion accelerator power supply have serious pollution to the power grid caused by low power factor of the grid side. Considering the characteristics of adjustable power factor and bidirectional energy transfer of the matrix converter, the possibility of which applied to the accelerator DC power supply is studied and three kinds of backup topology schemes including the preceding regulated matrix rectifier (MR) are proposed in this article. Given the actual situation of accelerator power supply, research has been focused on the modulation strategy suitable for the topology of the preceding regulated MR and simulation validation. Based on simulation of the preceding regulated MR scheme, a matrix power prototype is developed. A power factor tester is utilized to test grid side power factor. According to the experimental results, it is prospectively feasible to apply the preceding regulated MR topology to accelerator DC power supply, with excellent performance of the grid side.

“…However, existing methods mainly focus on summarization from a single document (without title) instead of considering various event elements contained in multiple documents of the same topic, which means they may meet challenges in the recognition of core event information and further coordination. Besides, a perfect short event description usually has more constraint in conciseness and event-centric expression than headlines, and has wider potential applications (Niu et al, 2014;Yang et al, 2021). For example, "Beirut explosion victim Isaac Oehlers was fatally struck by glass in his highchair."…”

Succinct event description based on multiple documents is critical to news systems as well as search engines. Different from existing summarization or event tasks, Multi-document Event Summarization (MES) aims at the query-level event sequence generation, which has extra constraints on event expression and conciseness. Identifying and summarizing the key event from a set of related articles is a challenging task that has not been sufficiently studied, mainly because online articles exhibit characteristics of redundancy and sparsity, and a perfect event summarization needs high level information fusion among diverse sentences and articles. To address these challenges, we propose a two-phase framework for the MES task, that first performs event semantic graph construction and dominant event detection via graph-sequence matching, then summarizes the extracted key event by an event-aware pointer generator. For experiments in the new task, we construct two large-scale real-world datasets for training and assessment. Extensive evaluations show that the proposed framework significantly outperforms the related baseline methods, with the most dominant event of the articles effectively identified and correctly summarized.

“…In the past few decades, the cooperative control of multi-agent systems (MASs) has aroused much concern due to its broad applications in diverse fields, such as distributed micro-grid systems [1], multi-robotic systems [2] and multiple unmanned aerial systems [3]. From the above-mentioned research, some significant theoretical results are involved, such as flocking [4], consensus [5][6][7][8][9][10], coordinated detection [11,12] and formation control [13][14][15][16]. Consensus control, as one of the most important problems for the cooperative control of MASs, is a group of agents working together to achieve synchronization of certain concerned states.…”

The guaranteed-performance consensus tracking (GPCT) for non-linear multi-agent systems (MASs) with switching communication topologies is presented. Different from the existing work, the non-linear range of one-sided Lipschitz non-linear MASs is wider than the Lipschitz ones, and the upper bound of the tracking performance is given while achieving the consensus tracking. First, a guaranteed-performance tracking control protocol is proposed, where consensus tracking regulation performance is involved. Then, by the linear matrix inequality (LMI), sufficient conditions are provided to achieve the GPCT under the one-sided Lipschitz and quadratic inner bounded conditions. It is worth noting that a special LMI structure is directly constructed by introducing these two conditions to simplify the complexity of the derivation. Finally, two simulation examples are provided to demonstrate the effectiveness of the proposed results.
