摘要：Bioprinting has been widely investigated for tissue engineering and regenerative medicine ***,it is still difficult to reconstruct the complex native cell arrangement due to the limited printing resolution of conventional bioprinting techniques such as extrusion-and inkjet-based ***,an electrohydrodynamic(EHD)bioprinting strategy was reported for the precise deposition of well-organized cell-laden constructs with microscale filament size,whereas few studies have been devoted to developing bioinks that can be applied for EHD bioprinting and simultaneously support cell *** study describes functionalized alginate-based bioinks for microscale EHD bioprinting using peptide grafting and fibrin incorporation,which leads to high cell viability(>90%)and cell *** printed filaments can be further refined to as small as 30μm by incorporating polyoxyethylene and remained stable over one week when exposed to an aqueous *** utilizing the presented alginate-based bioinks,layer-specific cell alignment along the printing struts could be observed inside the EHD-printed microscale filaments,which allows fabricating living constructs with cell-scale filament resolution for guided cellular orientation.

摘要：可变混响音质设计是建筑声学本科教学的重头戏。将可变混响音质设计建筑声学课堂教学从教室移至厦门大学科艺中心音乐厅及报告厅现场,结合教学大纲理论和实验环节要求,力争为学生创造身临其境的“情景化教学”的教学氛围,从而加深学生对MLS扩散体、QRD扩散体,以及可变混响音质设计的理解与认知,对接现有厦门大学科艺中心音乐厅可变混响虚拟仿真系统,实现音乐厅虚拟仿真数据模型、现场声学体验及实测数据的相互验证,是丰富教学手段的有益尝试。
