Summary: In this paper, a high-accuracy white-box TLP algorithm called DMAB is proposed by shifting the perspective of link prediction to the microscopic level of nodes. Two dynamic properties, node activity and node loyalty, are extracted and quantified to build the DMAB model. Comparative experiments with six state-of-the-art black-box methods on 12 real networks demonstrate that DMAB achieves excellent prediction performance and effectively captures network evolution mechanisms.

Summary: Cooperative communication among nodes on roads is crucial in vehicular networks, but selfish nodes greatly reduce network performance. Therefore, this paper proposes a novel detection scheme that takes into account link quality, mobility, and vehicle behaviors using fuzzy logic in a decentralized manner. Additionally, a perception module based on probabilistic calculations is deployed to improve detection decisions. Simulation results demonstrate that the proposed scheme outperforms conventional schemes in terms of Precision, Recall, and F1-score, with acceptable communication overhead.

Summary: As an important non-metallic strategic mineral resource, boron plays a vital role in the development of national emerging strategic industries. The international demand and trade volume of boron ore are increasing yearly, with closer trade relations and higher efficiency. Turkey holds the absolute export initiative in the boron ore international trade, while China and the United States are major importers and European countries serve as important transit countries. The import competition of boron ore is intensifying and concentrated, mainly with Turkey as the common import source, and future competition may shift to Latin America and Africa.

Summary: This study proposes an overlapping community detection method CDMG based on Graph Convolutional Networks (GCN) to maximize the Markov stability of community structure. Extensive experiments demonstrate the superiority of CDMG compared to other established community detection algorithms.

Summary: Neural implicit representations have gained attention due to their expressive, continuous, and compact properties. However, there is still a lack of research on city-scale continual implicit dense mapping based on sparse LiDAR input. In this study, a city-scale continual neural mapping system with a panoptic representation is developed, incorporating environment-level and instance-level modeling. A tailored three-layer sampling strategy and category-specific prior are proposed to address the challenges of representing geometric information in city-scale space and achieving high fidelity mapping of instances under incomplete observation.

Summary: This paper proposes a novel unsupervised context-aware quality phrase mining framework called LMPhrase, which is built upon large pre-trained language models. The framework mines quality phrases as silver labels using a parameter-free probing technique on the pre-trained language model BERT, and formalizes the phrase tagging task as a sequence generation problem by fine-tuning on the Sequence to-Sequence pre-trained language model BART. The results of extensive experiments show that LMPhrase consistently outperforms existing competitors in two different granularity phrase mining tasks.
