精美·朦胧·空幻·飘逸——浅谈印象派大师德彪西的钢琴音乐创作

德彪西是法国民族的天才，是在世纪之交时最具有独创性的伟大作曲家，他那精美、朦胧、空幻、飘逸的艺术风格特征，在钢琴艺术史上独树一帜。德彪西的钢琴音乐不但对钢琴演奏技术提出了新的课题，而且要理解和体验它们，还要从听觉感受、观念意识、心灵体验上，都要超越传统进行全方位的更新。     

Innovators and innovated: Newspapers and the postdigital future beyond the “death of print”

Along with other cultural organizations, newspapers, through waves of digital disruption, have become subject to a dominant narrative of crisis. But newspapers have long participated in change. A constructivist approach, qualified by consideration of media materiality, draws attention to diverse but essential processes of innovation around them. We see a contraflow of migration from digital to print, opening up a shared media space; bonding strategies are bringing multimedia to ink on paper, while bridging via boundary objects such as QR (Quick Response) codes are connecting the two. Among other initiatives, development of automation of news production and experiments with transparency are further evidence of an active embrace of change by newspapers that calls into question the discourse on their demise. This analysis inductively develops a nuanced account of the role of the newspaper as an object and as an institution. It suggests a hybrid, multifaceted, enduring presence of print in the complex media ecology of the future.     

Drone-based entanglement distribution towards mobile quantum networks

Satellites have shown free-space quantum-communication ability; however, they are orbit-limited from full-time all-location coverage. Meanwhile, practical quantum networks require satellite constellations, which are complicated and expensive, whereas the airborne mobile quantum communication may be a practical alternative to offering full-time all-location multi-weather coverage in a cost-effective way. Here, we demonstrate the first mobile entanglement distribution based on drones, realizing multi-weather operation including daytime and rainy nights, with a Clauser-Horne-Shimony-Holt S-parameter measured to be 2.41 ± 0.14 and 2.49 ± 0.06, respectively. Such a system shows unparalleled mobility, flexibility and reconfigurability compared to the existing satellite and fiber-based quantum communication, and reveals its potential to establish a multinode quantum network, with a scalable design using symmetrical lens diameter and single-mode-fiber coupling. All key technologies have been developed to pack quantum nodes into lightweight mobile platforms for local-area coverage, and arouse further technical improvements to establish wide-area quantum networks with high-altitude mobile communication.     

Unmanned Aerial Vehicles

Unmanned aerial vehicles (UAVs), commonly referred to as “drones,” have gained media attention over the last several years with much of the focus centering on their military uses and their emerging role in newsgathering. News organizations, journalists, and private citizens have employed UAVs to capture and share breaking news, to provide glimpses of natural disasters that would otherwise be too hazardous for journalists to obtain, and to offer unique perspectives that enrich news storytelling. At the same time, media scholars have emphasized the need to better understand the privacy and ethical concerns surrounding UAVs. Legal restrictions to and implications of their use have been relatively unexplored. Given that evolving rules and regulations put in place by the Federal Aviation Administration (FAA) may ground UAVs for journalistic purposes, it is important to understand what those legal barriers are and what they mean for the future of UAVs as tools for journalism. This paper advances by noting key benefits UAVs offer journalism before explicating the evolving rules and regulations of the FAA and how those are shaping the use of UAVs for journalism by private citizens, journalists, and news organizations.
