Spark Transformer: Reactivating Sparsity in FFN and Attention

Chong You, Kan Wu, Z. Jiao, Lin Chen et autres

The discovery of the lazy neuron phenomenon in trained Transformers, where the vast majority of neurons in their feed-forward networks (FFN) are inactive for each token, has spurred tremendous interests in activation sparsity for enhancing large model efficiency. While notable progress has …

Analysis of time characteristics during the breakdown process of argon gas switches

Zhaoxiang Wang, Guisheng Jiang, Yijun Zheng, Hongliang Ma et autres

Abstract This study establishes a two-dimensional fluid theoretical model for a two-electrode spark gap switch, linking the behavior of microscopic particles with the macroscopic discharge phase through multiscale dynamic coupling. It further investigates the temporal characteristics of the switch’s conductive process and …

Surface Functionalization of Graphene Oxide with Polymer Brushes for Improving Thermal Properties of the Polymer Matrix

Shuangshuang Wang, Houfang Chi, Lin Chen, Wei Li et autres

In this work, polymethyl methacrylate (PMMA) and polystyrene (PS) with controlled structures would be grafted on graphene material. The hybrid materials were prepared by coating graphene oxide (GO) with polydopamine (PDA) as a reactive underlayer and reducing agent, subsequently, surface-initiated polymerization of …

Gate-polarity-dependent doping effects of H 2 O adsorption on graphene/SiO 2 field-effect transistors

Mengjian Xu, Xuguang Guo, Lin Chen, Anqi Yu et autres

Abstract Due to its huge surface-to-volume ratio, graphene has become one of the most popular materials for sensors. However, H 2 O molecules in atmospheric environments can cause the instability of graphene devices, which greatly limits the practical applications of graphene devices. …
