Current studies have shown that the spatial-temporal graph convolutional network (ST-GCN) is effective for skeleton-based action recognition. However, existing ST-GCN-based methods, their temporal kernel size usually fixed over all layers, which makes them cannot fully exploit dependency between discontinuous frames and different sequence lengths. Besides, most of these methods use average pooling to obtain global feature from vertex features, resulting in losing much fine-grained...
We report the formation of large, branched silver aggregates after deposition Ag on silicone oil surfaces. The origin these ramified is traced to a two stage process, first which involves nucleation and growth disk-shaped clusters during deposition. In subsequent deposition, continue diffuse liquid surface by Brownian motion finally aggregate.
We present a template-based approach for preparing highly structured metallic films as effective surface-enhanced Raman scattering (SERS) substrates on the surface of uncured polydimethylsiloxane (PDMS). In contrast to commonly used liquid substrates, such silicone oil and ionic liquid, PDMS is distinguished by its controlled viscosity, rendering it suitable an adjustable stable substrate. On other hand, curing at appropriate times, can be easily transferred into cured substrate with high...
High-quality and catalyst-free fabrication of transition-metal dichalcogenides at room temperature has been a goal in the two-dimensional material research field. In this work, we report an efficient approach to synthesize high-quality tungsten disulfide (WS2) via optimized low-pressure chemical vapor deposition (LP-CVD) technique on ionic liquid surface near temperature. It is found that single- few-layered bulk-shaped (triangular hexagonal) WS2 crystals may be prepared simultaneously. The...

The anomalous deposition rate, which strongly depends nominal film thickness, can be interpreted under assumption of second evaporating penetrating effects. We find...
The surge of interest towards Multi-modal Large Language Models (MLLMs), e.g., GPT-4V(ision) from OpenAI, has marked a significant trend in both academia and industry. They endow (LLMs) with powerful capabilities visual understanding, enabling them to tackle diverse multi-modal tasks. Very recently, Google released Gemini, its newest most capable MLLM built the ground up for multi-modality. In light superior reasoning capabilities, can Gemini challenge GPT-4V's leading position learning?...
During the operation of gas insulated switchgear (GIS) and line (GIL), conducting bar generates joule heat, a non-uniform distribution temperature forms in bulk insulators. As load varies, changes, it has an influence on conductivity Moreover, surface charge accumulation can be affected. In order to clarify this, measurement system which could achieve control was constructed, model insulator with truncated cone type employed, as well two types high-voltage electrodes, i.e. plate needle...
