Smart Director: An Event-Driven Directing System for Live Broadcasting

Live video broadcasting normally requires a multitude of skills and expertise with domain knowledge to enable multi-camera productions. As the number of cameras keeps increasing, directing a live sports broadcast has now become more complicated and challenging than ever before. The broadcast directors need to be much more concentrated, responsive, and knowledgeable, during the production. To relieve the directors from their intensive efforts, we develop an innovative automated sports broadcast directing system, called Smart Director, which aims at mimicking the typical human-in-the-loop broadcasting process to automatically create near-professional broadcasting programs in real-time by using a set of advanced multi-view video analysis algorithms. Inspired by the so-called “three-event” construction of sports broadcast [ 14 ], we build our system with an event-driven pipeline consisting of three consecutive novel components: (1) the Multi-View Event Localization to detect events by modeling multi-view correlations, (2) the Multi-View Highlight Detection to rank camera views by the visual importance for view selection, and (3) the Auto-Broadcasting Scheduler to control the production of broadcasting videos. To our best knowledge, our system is the first end-to-end automated directing system for multi-camera sports broadcasting, completely driven by the semantic understanding of sports events. It is also the first system to solve the novel problem of multi-view joint event detection by cross-view relation modeling. We conduct both objective and subjective evaluations on a real-world multi-camera soccer dataset, which demonstrate the quality of our auto-generated videos is comparable to that of the human-directed videos. Thanks to its faster response, our system is able to capture more fast-passing and short-duration events which are usually missed by human directors.

Intestinal organoids in co-culture: Redefining the boundaries of gut mucosa ex vivo modeling

All-time preservation of an intact mucosal barrier is crucial to ensuring intestinal homeostasis and, hence, the organism's overall health maintenance. This complex process relies on an equilibrated signaling system between the intestinal epithelium and numerous cell populations inhabiting the gut mucosa. Any perturbations of this delicate crosstalk, particularly regarding the immune cell compartment and microbiota, may sustainably debilitate the intestinal barrier function. As a final joint event, a critical rise in epithelial permeability facilitates the exposure of submucosal immunity to microbial antigens, resulting in uncontrolled inflammation, collateral tissue destruction and dysbiosis. Organoid-derived intestinal co-culture models have established themselves as convenient tools to re-enact such pathophysiological events, explore interactions between selected cell populations and assess their roles with a central focus on intestinal barrier recovery and stabilization.

Rebuilding Post-Pandemic Societies: Editorial Section

INDONESIAN SCHOLARS SCIENTIFIC SUMMIT (I3S) 2021 & OISAA ASIA-OCEANIA SYMPOSIUM 2021 DefinitionIndonesian Scholars Scientific Summit (I3S) 2021 is a scientific conference involving Indonesian scholars who currently work or study in Taiwan and outside of Taiwan, such as Indonesia and other countries. This event is conducted by Perhimpunan Pelajar Indonesia (PPI) Taiwan, which is the Overseas Indonesian Student’s Association Alliance in Taiwan, in collaboration with Perhimpunan Pelajar Indonesia Dunia Kawasan (PPIDK) Asia-Oceania or the Overseas Indonesian Student’s Association Alliance for Asia-Oceania Region, who have their annual symposium in 2021. These two associations are referred to as PPI Taiwan and OISAA Asia-Oceania, throughout this conference. The joint event of I3S 2021 and the OISAA Asia-Oceania Symposium 2021 is scheduled to be conducted on June 21-27, 2021 and being hosted by PPI Taiwan. The main event is taking place on June 25-27, 2021 which is prompted by four days of pre-event series on June 21-23, 2021. BackgroundDated back on December 31, 2019, the World Health Organization (WHO) received a notification of pneumonia disease, whose source was unidentified, in Wuhan, China. Then, the disease which was caused by the SARS-CoV-2 virus was referred by WHO as COVID-19. The COVID-19 was designated by WHO as a pandemic on March 11, 2020. Furthermore, by January 29, 2021, as many as 102.6 million cases of COVID-19 worldwide with more than 2.2 million deaths have been reported by WHO. Globally, five countries experiencing the highest number of COVID-19 positive cases are the United States, India, Brazil, Russia and Great Britain. The COVID-19 pandemic has caused not only casualties but also opens up opportunities, among others are in the fields of technology, education and health. In the field of technology, we can observe the increasing use of technology for distance or remote education and the utilization of Artificial Intelligence (AI) in various fields including health. In the health sector, technology related to telemedicine and vaccines has also begun to develop. There has also been an expectation that within the post- COVID-19 period, the novel ideas keep developing, and Indonesia can take an active role in developing this. Regarding the aforementioned situation, the establishment of the 2021 Indonesian Scholar Scientific Summit (I3S 2021) is expected to serve as a scientific forum for exchanging ideas among scientists, students and industry practitioners in all relevant fields in order to generate innovative ideas that can be developed in the post-COVID-19 pandemic situation. Objectives To promote the development of scientific ideas from and among the participants and speakers. To disseminate new knowledge to the participants, committees, and speakers. To establish a network among the participants, committees, and speakers. To increase awareness on current issues related to the conference’s theme.

Passport to the oceans of the future: delivering marine energy with science linked to policy

In February 2021, a group from MASTS, Environmental Interactions of Marine Renewables (EIMR) and Marine Scotland began exploring options for a joint event on marine energy science and policy development. The original concept was to bridge the gap between events that each group would normally arrange ‘in person’ and the virtual world in which we were all currently existing. Encouraged by the online support and experience available from MASTS, a steering group decided to arrange a workshop. In order to straddle our interests, the starting point was the capacity of the North Sea to deliver renewable energy. We wanted to include emerging science and the timing of the review of Scotland’s National Marine Plan provided an excellent context. We sought to deliver a wide range of content but encourage participant conversation. We aimed for a range of speakers delivering 7-minute recorded talks. Talks included findings from funded research, ongoing projects, and some emerging thinking across the science policy interface for marine planning. Marine energy was interpreted in the widest of senses, but the main focus was on offshore wind in UK waters, with particular detail about Scotland.

TDJEE: A Document-Level Joint Model for Financial Event Extraction

Extracting financial events from numerous financial announcements is very important for investors to make right decisions. However, it is still challenging that event arguments always scatter in multiple sentences in a financial announcement, while most existing event extraction models only work in sentence-level scenarios. To address this problem, this paper proposes a relation-aware Transformer-based Document-level Joint Event Extraction model (TDJEE), which encodes relations between words into the context and leverages modified Transformer to capture document-level information to fill event arguments. Meanwhile, the absence of labeled data in financial domain could lead models be unstable in extraction results, which is known as the cold start problem. Furthermore, a Fonduer-based knowledge base combined with the distant supervision method is proposed to simplify the event labeling and provide high quality labeled training corpus for model training and evaluating. Experimental results on real-world Chinese financial announcement show that, compared with other models, TDJEE achieves competitive results and can effectively extract event arguments across multiple sentences.
