ABSTRACT Melt electrowriting (MEW) is an emerging 3D printing technology that can precisely fabricate micro‐nano fibrous scaffolds and has significant application prospects in tissue engineering. This paper reviews the latest progress of MEW engineering scaffold fabrication, including its working principle, key design factors, various processable biomaterials. The enhancement function through filler addition, post‐treatment modification, combining with other manufacturing technologies are...
Terahertz (THz) communication is becoming a key technology for future 6G wireless networks because of its ultra-wide band.However, the implementation THz systems confronts formidable challenges, notably beam splitting effects and high computational complexity associated with them.Our primary objective to design hybrid precoder that minimizes Euclidean distance from fully digital precoder.The analog precoding part adopts delay-phase alternating minimization (DP-AltMin) algorithm, which...
As mobile nodes roam in a wireless network, they continuously associate with different access points and perform handoff operations. However, frequent handoffs can potentially incur unacceptable delays even interruptions for interactive applications. To alleviate these negative impacts, we present novel association control algorithms that minimize the frequency of occurred to devices. Specifically, show greedy LookAhead algorithm is optimal offline setting, where user's future mobility...
Reconfigurable intelligent surface (RIS) holds great promise as communication aid which is capable of controlling the electromagnetic propagation environment by adjusting phase shift reflective elements. However, in RIS-assisted multi-user wireless systems, channel estimation challenging due to inclusion a large number passive elements within RIS. To address this problem, we take advantage sparsity inherent cascade channels and propose novel strategy with low pilot overhead. Specifically,...
