Biochar and pyroligneous acid contributed to the sustainable reduction of ammonia emissions: From compost process to soil application.

Aerobic composting is vital for resource recycling but struggles with high ammonia (NH) emissions. Biochar (BC) and pyroligneous acid (PA), products of waste pyrolysis, have great potential for reducing NH emissions. However, the effective utilization of BC and PA to reduce NH emissions in both compost process and product application remains unclear.

Progressive Temporal-Spatial-Semantic Analysis of Driving Anomaly Detection and Recounting.

For analyzing the traffic anomaly within dashcam videos from the perspective of ego-vehicles, the agent should spatial-temporally localize the abnormal occasion and regions and give a semantically recounting of what happened. Most existing formulations concentrate on the former spatial-temporal aspect and mainly approach this goal by training normal pattern classifiers/regressors/dictionaries with large-scale availably labeled data. However, anomalies are context-related, and it is difficult to distinguish the margin of abnormal and normal clearly.
