中国海洋文明是推动海洋强国建设的内生动力,是建设中华民族现代文明的重要组成部分。由于时代变迁,学界对海洋文化概念内涵的认知不断变化,加强海洋文化建设,需要对中国海洋文明的概念话语有正确的认知。融合历史与当代的概念内涵变迁,对海洋文明的概念话语加以重新审视、修正和重构,分别不同类型,排列组合为海洋环境、海洋经济、海洋社会、海洋文化四个层级的概念话语体系,使之成为思考和研究的工具,打破西方话语霸权,发展和创新海洋文明理论,顺应时代要求,推动中国海洋文明在新时代开启新征程,取得新成就。

当今社会,对象化的技术因能提高生产效率、使人的欲望得到虚拟满足等而备受重视,但因导致人的异化而受到技术哲学的指责。人的生命兼顾精神性与肉身性,武术是“身体-技术-艺术”技道合一的身体技术,能以“联觉”拓展“外在”,体悟万物一体的生命存在,“体-身-神”形神合一而与道贯通。技术至上背景下,武术一定程度被抽离了“体”之当下全息感知觉与“身”之共情整全性的生命体验与精神意义,异化为符号化的操化技术。新时代,武术应借助触觉复归身体感作为身体技术的使命与选择,拓展以人为目的的多维感知空间,具身体证“始于情、终于情”的生命情感,在切身感的身体直觉和世界互渗的精神自由中贯通生命之道,践行武术“锻炼行道、练以成人”的生命理想与精神追求。

With the advances in the field of flexible fibre technology in recent years,a variety of flexible fibres with different preparation processes have emerged[1,2].However,most of the flexible fibres in the past have structural breaks,making them unsuitable for long-term use as wearable fabrics[3,4].Glass semiconductors are widely used in thermally stretched fibres due to their advantages such as controllable fluidity,but they suffer from electronic defects compared with crystalline semi conductors in electronic semiconductors such as silicon(Si)and germanium(Ge)[5].Obviously,the semiconductor component in flexible optic fibres is a key component in regulating their mechanical and electrical properties[6].

Photons with variable energy, high coherency, and switchable polarization provide an ideal tool-kits for exploring the cutting-edge scientific questions in the condensed matter physics and material sciences. Over decades, extensive researches in the sample fabrication and excitation have employed the photon as one of the important means to synthesize and explore the low-dimensional quantum materials. In this review, we firstly summarize the recent progresses of the state-of-the-art thin-film deposition methods using excimer pulsed laser, by which syntactic oxides with atomic-unit-cell-thick layers and extremely high crystalline quality can be programmatically fabricated. We demonstrate that the artificially engineered oxide quantum heterostructures exhibit the unexpected physical properties which are absent in their parent forms. Secondly, we highlight the recent work on probing the symmetry breaking at the surface/interface/interior and weak couplings among nanoscale ferroelectric domains using optical second harmonic generation. We clarify the current challenges in the insitu characterizations under the external fields and large-scale imaging using optical second harmonic generation. The improvements in the sample quality and the non-contact detection technique further promote the understanding of the mechanism of the novel properties emerged at the interface and inspire the potential applications, such as the ferroelectric resistive memory and ultrahigh energy storage capacitors.

Respiratory diseases rank as the third leading cause of adult mortality[1],while cardiopulmonary and gastrointestinal issues are the primary cause of death within the first five years of a child’s life[2].The monitoring of cardiac,respiratory,and gastrointestinal sounds plays a vital role in routine care,as alterations or absence of these body sounds can serve as indicators of underlying diseases.
