Abstract In many noise scenarios, ventilation is necessary. The practical realization of noise attenuation under the premise of ensuring ventilation is an urgent problem to be solved. In this paper, a ventilated acoustic metamaterial labyrinth (VAML)

Abstract Despite the existence of various super‐resolution (SR) methods, most of them focus on designing models for specific upscaling factors rather than fully exploiting inter‐scale correlation to improve efficiency. In contrast, multi‐scale

Low-frequency noise absorbers often require large structural dimensions, constraining their development in practical applications. In order to improve space utilization, an acoustic metamaterial with a spatial double helix, called a spatial double he

In many noise scenarios, it is necessary to ensure ventilation and noise suppression. In this paper, a ventilated acoustic metamaterial labyrinth plate (VAMLP), formed by an array of labyrinth cells (LCs), is presented. Each labyrinth cell contains f

Abstract Compared with convolutional operation, non‐local operation can directly capture long‐range dependencies and thus has a larger receptive field. However, the computation and memory consumption of non‐local operation is much higher than c

The objective of this study was to prepare high-elasticity and high-strength ovalbumin (OVA) gels by comparing the gelling behaviors under the four treatments (alkali-induced, AI; heat-induced, HI; alkali-heat-induced, AHI; and alkali-heat-induced in

The heat flux rises dramatically as electronic circuits become more integrated. Flat micro-heat pipe (FMHP) is a popular device for high heat flux management. A novel sintered multi-size copper powder wick (SMW) is designed in this paper. The evapora

The operating parameters of the active direct methanol fuel cell (DMFC) are essential factors that affect cell performance. However, it is challenging to maintain the optimal maximum output power density due to the system’s complexity, the operatin
